Ecuador, the smallest of the Andean countries, is located in the northwest portion of South America. The nation's 14.5 million people have a tremendous need for high quality primary care. To describe the profound advances as well as the persistent needs in medical education in Ecuador that have occurred with globalization and with the modernization of the country. Through an extensive search of the literature; medical school data; reports from the Ecuador Ministry of Public Health and Ministry of Education; and information from the National Secretary of Higher Education, Science, and Innovation (SENESCYT), the medical education system in Ecuador has been thoroughly examined. The National System of Higher Education in Ecuador has experienced significant growth over the last 20 years. As of 2009 the system boasts 19 medical schools, all of which offer the required education needed to obtain the title of Physician, but only 12 of which offer postgraduate clinical training. Of these 19 universities, nine are public, five are private and self-financed, and five are private and co-financed. Post-graduate options for medical students include: (1) Clinical specialization, (2) Higher diploma, (3) Course specialization, (4) Master's degree, and (5) PhD degree. The rapid growth of Ecuador's system of medical education has led to inevitable gaps that threaten its ability to sustain itself. Chief among these is the lack of well-trained faculty to supply its medical schools. To ensure an adequate supply of faculty exists, the creation of sufficient postgraduate, sub-specialization, and PhD training positions must be created and maintained.

Vulnerability assessments have become necessary to increase the understanding of climate-sensitive systems and inform resource allocation in developing countries. Challenges arise when poor economic and social development combines with heterogeneous climatic conditions. Thus, finding and harmonizing good-quality data at local scale may be a significant hurdle for vulnerability research. In this paper we assess vulnerability to climate change at a local level in Ecuador. We take Ecuador as a case study as socioeconomic data are readily available. To incorporate the spatial and temporal pattern of the climatic variables we use reanalysis datasets and empirical orthogonal functions. Our assessment strategy relies on the statistical behavior of climatic and socioeconomic indicators for the weighting and aggregation mechanism into a composite vulnerability indicator. Rather than assuming equal contribution to the formation of the composite indicator, we assume that the weights of the indicators vary inversely as the variance over the cantons (administrative division of Ecuador). This approach captures the multi-dimensionality of vulnerability in a comprehensive form. We find that the least vulnerable cantons concentrate around Ecuador's largest cities (e.g. Quito and Guayaquil); however, approximately 20 % of the national population lives in other cantons that are categorized as highly and very highly vulnerable to climate change. Results also show that the main determinants of high vulnerability are the lack of land tenure in agricultural areas and the nonexistence of government-funded programs directed to environmental and climate change management.

Background Tropical and zoonotic diseases are major problems in developing countries like Ecuador. Poorly designed houses, the high proportion of isolated indigenous population and under developed infrastructure represent a fertile environment for vectors to proliferate. Control campaigns in Ecuador over the years have had varying success, depending on the disease and vectors targeted. Aims In our study we analyse the current situation of some neglected diseases in Ecuador and the efficiency of the control campaigns (by measuring changes in numbers of cases reported) that the Ecuadorian government has been running to limit the spread of these infectious and parasitic diseases. Results Our study reveals that Brucellosis, Chagas Disease, Rabies and Onchocerciasis have been controlled, but small outbreaks are still detected in endemic areas. Leptospirosis and Echinococcosis have been increasing steadily in recent years in Ecuador since the first records. The same increase has been reported world-wide also. Better diagnosis has resulted in a higher number of cases being identified, particularly with regard to the linking of outdoor activities and contact with farm animals as contributing vectors. Improvements in diagnosis are due to regular professional training, implementation of automatized systems, establishing diagnosis protocols and the creation of an epidemiological vigilance network that acts as soon as a case is reported. Conclusion Control campaigns performed in Ecuador have been successful in recent years, although natural phenomena limit their efficiency. Leptospirosis and Echinococcosis infections remain a growing problem in Ecuador as it is worldwide. PMID:26394405

There is a lack of published information on the causes of blindness in Ecuador and the Latin American region in general. This study is designed to enumerate the proportions of ocular conditions contributing to blindness in an outpatient population of an ophthalmology hospital in the coastal region of Ecuador. All cases presenting to an ophthalmology outpatient clinic over a 3-week period during September 2004 were reviewed (n = 802). Visual acuity was measured using a Snellen acuity chart and those who met the criteria for blindness were included in the study (n = 118). Blindness was defined under the World Health Organization protocol as visual acuity of glaucoma (15%). Among those considered to have bilateral blindness (n = 30), refraction was the most common cause (37%), followed by cataract (23%) and glaucoma (17%). The major causes of blindness found in this study reflected those in estimated data for the region. More studies are needed to improve the quality and quantity of epidemiological data on blindness in Ecuador and Latin America. Many obstacles to successful implementation of prevention of blindness programmes in South America still need to be overcome.

Full Text Available Bovine tuberculosis (BTB is a chronic and contagious disease that affects domestic animals, wildlife, and humans. Caused by Mycobacterium bovis, BTB causes major economic losses and poses a serious constraint to international livestock trade. Moreover, in developing countries where BTB controls are lacking, M. bovis is a public health concern. In most developing countries, the prevalence of BTB in livestock is unknown because the information is either not reported or not available. In Ecuador, there is no national BTB control program. This article reviews the BTB situation in Ecuador by examining exhaustive data from tuberculin testing surveys and slaughterhouse surveillance studies conducted in 1972-2008 in a variety of the country's geographic areas. In Ecuador, several factors, including the dairy industry's expansion (preempted by the high demand for milk and its by-products, intensified efforts to increase the cattle population, the presence of M. bovis, and a lack of BTB controls, have caused a rise in BTB prevalence, and consequently, a growing push for the implementation of a national BTB control program.La tuberculosis bovina es una enfermedad contagiosa crónica que afecta a los animales domésticos, los animales salvajes y los seres humanos. Es producida por Mycobacterium bovis; causa grandes pérdidas económicas y plantea una grave limitación para el comercio ganadero internacional. Por otro lado, en los países en desarrollo donde no hay controles de la tuberculosis bovina, la infección por M. bovis representa un problema de salud pública. En la mayoría de los países en desarrollo, la prevalencia de tuberculosis en el ganado se desconoce porque la información no se comunica o no se consigue. En el Ecuador no hay un programa nacional de control de la tuberculosis bovina. En este artículo se revisa la situación de la tuberculosis bovina en el Ecuador, sobre la base de un análisis de los datos exhaustivos obtenidos de

Biogeography of Triatominae (Hemiptera: Reduviidae in Ecuador: implications for the design of control strategies

Full Text Available Chagas disease control strategies strongly depend on the triatomine vector species involved in Trypanosoma cruzi transmission within each area. Here we report the results of the identification of specimens belonging to various species of Triatominae captured in Ecuador (15 species from 17 provinces and deposited in the entomological collections of the Catholic University of Ecuador (Quito, Instituto Oswaldo Cruz (Brazil, the Natural History Museum London (UK, the London School of Hygiene and Tropical Medicine (UK, the National Institute of Hygiene (Quito, and the Vozandes Hospital (Quito. A critical review of published information and new field records are presented. We analysed these data in relation to the life zones where triatomines occur (11 life zones, excluding those over 2,200 m altitude, and provide biogeographical maps for each species. These records are discussed in terms of epidemiological significance and design of control strategies. Findings relevant to the control of the main vector species are emphasised. Different lines of evidence suggest that Triatoma dimidiata is not native to Ecuador-Peru, and that synanthropic populations of Rhodnius ecuadoriensis in southern Ecuador-northern Peru might be isolated from their sylvatic conspecifics. Local eradication of T. dimidiata and these R. ecuadoriensis populations might therefore be attainable. However, the presence of a wide variety of native species indicates the necessity for a strong longitudinal surveillance system.

Diet is an important factor related to the development of numerous diseases. In developing countries like Ecuador, this aspect is not considered as priority however, the study of the incidence of certain diet-related diseases could help to assess consumption habits of a country from a Public Health perspective and support national nutrition policies and programs. The objective the present study is to investigate the mortality rate of certain diet-related diseases in Ecuador and its possible relationship with Ecuadorian consumption habits. For that, mortality rates (2001-2008) associated with five different disease groups related to dietary factors (cancer of colon, cerebrovascular diseases, cardiovascular diseases, diabetes mellitus and liver diseases) were collected, analyzed and compared to consumption patterns in Ecuador. According to results, Ecuador has a low level of cancer of colon in comparison with developed countries (e.g. Spain). The group with the highest number of deaths corresponded to cardiovascular diseases followed by cerebrovascular diseases. The mortality study per province revealed that Amazonian provinces showed few deaths in relation to other provinces in Ecuador. This could be due to different factors including fails in the disease surveillance information systems, environmental factors and consumption patterns. In this sense, further investigation on native products consumption such as "chontaduro" might help to find valuable foods contributing to healthier Ecuadorian diet. These results, though preliminary, evidence that a major effort should be made by national and international organisations to collect data on consumption patterns and nutritional aspects of the Ecuadorian population in order to better support the development of effective food security and nutrition policies.

To determine the prevalence of metabolic syndrome and prediabetes in a population of the city of Guayaquil, Ecuador, aged 55-65 years; to observe if there are differences in prevalence between males and females, and to describe the frequency with which each component of the metabolic syndrome is found in this population. population-based cross-sectional study in Guayaquil. We recruited people of both genders, with ages ranging from 55 to 65 years. Through clinical history, physical examination and laboratory tests, we obtained necessary data to diagnose metabolic syndrome and/or prediabetes. Statistical analysis was performed using SPSS(®) 22. we obtained a sample of 213 patients, 64.5% were females and 35.5% were males. Mean age was 60.3 years (±3.1). A total 65.8% of patients had increased waist circumference, and 45% were diagnosed with metabolic syndrome. Hypertriglyceridemia was the most prevalent condition in males, while women more commonly had low HDL. Prediabetes was diagnosed in 45.9% of our patients, and 19.5% had both disorders. There was no significant difference on metabolic syndrome prevalence between genders, but prediabetes was significantly more common in women. we found a high prevalence of metabolic syndrome and prediabetes in Guayaquil, higher than what was reported in other areas. Abdominal obesity is even more prevalent. Women have prediabetes more frequently than men. Our patients, given their age, are at higher risk of cardiovascular disease and cognitive decline by having metabolic syndrome and/or prediabetes. Copyright © 2016 Diabetes India.

Cerebral small vessel disease is probably one of the most common pathogenetic mechanisms underlying stroke in Latin America. However, the importance of silent markers of small vessel disease, including white matter hyperintensities of presumed vascular origin, has not been assessed so far. The study aims to evaluate prevalence and correlates of white matter hyperintensities in community-dwelling elders living in Atahualpa (rural Ecuador). Atahualpa residents aged ≥ 60 years were identified during a door-to-door survey and invited to undergo brain magnetic resonance imaging for identification and grading white matter hyperintensities and other markers of small vessel disease. Using multivariate logistic regression models, we evaluated whether white matter hyperintensities is associated with demographics, cardiovascular health status, stroke, cerebral microbleeds, and cortical atrophy, after adjusting for the other variables. Out of 258 enrolled persons (mean age, 70 ± 8 years; 59% women), 172 (67%) had white matter hyperintensities, which were moderate to severe in 63. Analyses showed significant associations of white matter hyperintensities presence and severity with age and cardiovascular health status, as well as with overt and silent strokes, and a trend for association with cerebral microbleeds and cortical atrophy. Prevalence and correlates of white matter hyperintensities in elders living in rural Ecuador is almost comparable with that reported from industrialized nations, reinforcing the concept that the burden of small vessel disease is on the rise in underserved Latin American populations. © 2014 World Stroke Organization.

The global urban population is increasing rapidly, but patterns of urban expansion differ greatly among countries. Urban transition theory predicts that the shift from low to high urbanization depends on a country's history and level of economic development. This study describes urban expansion in Colombia, Ecuador, Peru, and Bolivia between 1992 and 2009. Urban dynamics were analyzed by combining nighttime lights and census data from 4032 municipalities. High-lit areas (>52-63 pixel values) were correlated with urban populations across municipalities and years (R (2) > 0.90). Analyses showed that between 1992 and 2009 Bolivia and Ecuador had rapid population growth and rapidly increasing high-lit areas, while Peru and Colombia had lower rates of population growth and urbanization (i.e., expansion of high-lit areas). We demonstrate how nighttime lights can be a useful tool, providing a homogeneous platform for multi-scale analyses of urban growth.

Current status of Paragonimus and paragonimiasis in Ecuador

Full Text Available A review of national and international publications on paragonimiasis in Ecuador, epidemiological records from the Ministry of Public Health and unpublished research data was conducted to summarise the current status of the parasite/disease. The purpose of the review is to educate physicians, policy-makers and health providers on the status of the disease and to stimulate scientific investigators to conduct further research. Paragonimiasis was first diagnosed in Ecuador 94 years ago and it is endemic to both tropical and subtropical regions in 19 of 24 provinces in the Pacific Coast and Amazon regions. Paragonimus mexicanus is the only known species in the country, with the mollusc Aroapyrgus colombiensis and the crabs Moreirocarcinus emarginatus, Hypolobocera chilensis and Hypolobocera aequatorialis being the primary and secondary intermediate hosts, respectively. Recent studies found P. mexicanus metacercariae in Trichodactylus faxoni crabs of the northern Amazon. Chronic pulmonary paragonimiasis is commonly misdiagnosed and treated as tuberculosis and although studies have demonstrated the efficacy of praziquantel and triclabendazole for the treatment of human infections, neither drug is available in Ecuador. Official data recorded from 1978-2007 indicate an annual incidence of 85.5 cases throughout the 19 provinces, with an estimated 17.2% of the population at risk of infection. There are no current data on the incidence/prevalence of infection, nor is there a national control programme.

AFLP analysis of Genetic Diversity Among Different Jatropha curcas L. Genotypes from Africa and Ecuador

2018-01-01

Full Text Available Six populations amounting to a total number of seventy genotypes of Jatropha curcas L. originating from Africa (Senegal, Mali, Burkina Faso and Madagascar and Ecuador were investigated for genetic diversity using two AFLP primer combinations. The results revealed a high genetic diversity in the populations studied. The population with greatest genetic diversity was Madagascar (He = 0.2638 and I = 0.4066 and the least diverse was Senegal-Tamba (He = 0.1962 and I = 0.3079. AMOVA (analysis of molecular variance detected the highest proportion of variation within populations (81% of the total molecular variation. This may be attributed to the high level of allogamy observed in this species. The Nei's standard unbiased genetic distance (D between the populations ranged from 0.010 (Senegal-Tamba and Burkina Faso to 0.131 (Mali and Ecuador; the average was 0.063. Analysis of the genetic relationships among the 6 populations using both neighbor-joining cluster analysis and principal component analysis (PCoA showed five clusters with globally, groupings of i most of Burkina Faso and Senegal-Tamba genotypes, ii most of Mali and Senegal-Diobass genotypes , iii most of Madagascar and Ecuador genotypes, and iv some mixings of genotypes with different origins. Considering the distance existing between the different origins there are prospects to develop F1 hybrids. The greatest heterosis might be expected from crossing involving genotypes of cluster I and cluster V which group the more distant genotypes. Such crossing schemes might produce greater success in the production of genetic variability and might maximize the exploitation of heterosis and segregation.

This study was carried out since 1990 to 1997. The goal was to figure out different species of fruit fly that inhabit in Ecuador. For the identification we put special emphasis in the female genitalia. We recommend to do more research into this subject, because of the few studies done in our country and the importance of fruit cultivation. We mention 32 genus in the family Tephritidae in Ecuador, including the introduced genus Ceratitis. Into Toxotrypaninae are pointing out the presence of one specie of the Toxotrypana genus and 31 species of the Anastrepha genus, detailing brilly the 27 species most common. General notions about taxonomic bases are mentioned in order to identify species of the Anastrepha Schiner, pointing out certain fenotipic characteristics that prove variability among the ecuadorian's population, mainly A. fraterculus, A. distincta, A. obliqua, A. striata, and others.

Students seeking degrees in healthcare in Ecuador participate in community improvement projects and provide free health services under the supervision of faculty health professionals. The aim of this study is to determine the impact of a community-based intervention delivered by nursing students on health-related quality of life (HRQoL) and perceived social support of a rural population in Ecuador. A quasi-experimental non-equivalent control group design study was conducted in two rural communities in Tumbaco, Ecuador. Families from one rural community were invited to participate in the intervention, receiving 8 weekly home visits from nursing students. Families from a neighboring community were similarly recruited as wait-list controls. One member of each family was consented into the study; the final sample included 43 intervention participants and 55 control participants. HRQoL and perceived social support were assessed before and after the intervention in both groups. The SF-12 was used to measure HRQoL, including eight domain scores and two composite scores, and the Interpersonal Support Evaluation List was used as an indicator of perceived social support. Difference-in-differences (DD) analyses were conducted to mitigate the effects of any baseline differences in the non- equivalent control group design. When compared to the control group, the intervention group realized significant improvements in the physical component summary score of the SF-12 (4.20, p based learning on recipient populations.

This paper reports that oil companies operating in Ecuador plan to quicken the pace of oil development this year. After delays in 1991, companies plan a series of projects to develop reserves discovered the past 3 years estimated at more than 600 million bbl. Oil and Gas Journal estimated Ecuador's proved crude reserves at 1.55 billion bbl as of Jan. 1, 1992. The development push is part of a larger effort needed to ensure Ecuador's status as an oil exporter into the next century. Ecuador is the smallest crude oil producer and exporter in the Organization of Petroleum Exporting Countries

We have identified 56 patients with GH receptor deficiency (Laron syndrome) from two provinces in southern Ecuador, one group of 26 (Loja province) with a 4:1 female predominance and 30 patients from neighboring El Oro province with a normal sex ratio. There were no significant differences between the Loja and El Oro populations in stature (-5.3 to -11.5 standard deviation score), other auxologic measures, or in biochemical measures. GH binding protein, the circulating extracellular domain of the GH receptor, was measured by ligand immunofunction assay and found to be comparably low in children and adults. Levels of insulin-like growth factor (IGF)-I and -II and the GH-dependent IGF binding protein-3 (measured by RIA) were significantly greater, and GH and IGF binding protein-2 levels significantly lower in adults than children. Levels of IGF-I (adults) and IGF binding protein-3 (children and adults) correlated inversely with statural deviation from normal (P < 0.01). School performance was at an exceptionally high level, 41 out of 47 who had attended school being in the top 3 in classes of 15-50 persons.

Cockroaches are an understudied group and the total number of described taxa increases every year. The last checklist of Ecuador species was published in 1926. The main aim of this study was to complete a new checklist of cockroach species recorded in Ecuador supplemented with a research history of cockroaches (Blattaria) on the territory of continental Ecuador. In addition, the checklist contains comments on Ecuadorian faunistic records, including the Galápagos Islands. A total of 114 species (105 in continental Ecuador and 18 in Galápagos Islands) belonging to 6 families and 44 genera are listed. Forty species (38.1 %) occur solely in continental Ecuador and five (27.8 %) are endemic on Galápagos Islands. The results indicate that further research on the cockroach fauna of Ecuador as well as determination of museum collections from this territory is needed.

2016-10-01

Full Text Available The development of biofertilizers based on Rhizobium strains for common bean (Phaseolus vulgaris L. requires studies about bacterial interaction with target cultivars. For these reason, the aim of this paper was to determine the effect of the inoculation of Rhizobium native strains, isolated from southern Ecuador, on P. vulgaris cultivar Mantequilla. An assay was performed in greenhouse. It were evaluated the parameters of nodulation, biomass, nitrogen fixation and efficiency of the symbiosis. All inoculated strains were able to nodulate bean seedlings. The total number of nodules, nodular biomass and plant biomass, were favourably affected by inoculation of Rhizobium strains. The best results were obtained with R. mesoamericanum NAM1, R. leguminosarum COL 6 and R. etli PIN 1 strains. The experimental evidences shows the potential of native strains of Rhizobium for it use as biofertilizers because they are able to raise the rates of nitrogen fixation in common bean in southern Ecuador.

Full Text Available OBJECTIVE:A decision-analytic model was constructed to evaluate the economic impact of post-introduction pneumococcal conjugate vaccine (PCV programs in Ecuador, Honduras, and Paraguay from the societal perspective. METHODS: Hypothetical birth cohorts were followed for a 20-year period in each country. Estimates of disease burden, vaccine effectiveness, and health care costs were derived from primary and secondary data sources. Costs were expressed in 2014 US$. Sensitivity analyses were performed to assess the impact of model input uncertainties. RESULTS: Over the 20 years of vaccine program implementation, the health care costs per case ranged from US$ 764 854 to more than US$ 1 million. Vaccination prevented more than 50% of pneumococcal cases and deaths per country. At a cost of US$ 16 per dose, the cost per disability-adjusted life year (DALY averted for the 10-valent PCV (PCV10 and the 13-valet PCV (PCV13 ranged from US$ 796 (Honduras to US$ 1 340 (Ecuador and from US$ 691 (Honduras to US$ 1 166 (Ecuador respectively. At a reduced price (US$ 7 per dose, the cost per DALY averted ranged from US$ 327 (Honduras to US$ 528 (Ecuador and from US$ 281 (Honduras to US$ 456 (Ecuador for PCV10 and PCV13 respectively. Several model parameters influenced the results of the analysis, including vaccine price, vaccine efficacy, disease incidence, and costs. CONCLUSIONS: The economic impact of post-introduction PCV needs to be assessed in a context of uncertainty regarding changing antibiotic resistance, herd and serotype replacement effects, differential vaccine prices, and government budget constraints.

2007-01-01

This paper describes the current energy sector in Ecuador, its present structure, the oil industry, subsidies, and renewable energy, focusing on the evolution and reform of the electricity sector. Currently, 86% of the primary energy originates from nonrenewable sources. In 2005, the gross electricity generation was 15 127 GWh (45.5% hydropower, 43.11% thermal, and 11.39% imported). Ecuador is the fifth largest oil producer in South America but lacks sufficient oil refining capacity. Reserves of natural gas (NG) are small, and most of NG is produced from oil fields without energy recovery. Several projects are underway to increase the utilization of NG and renewable energies to meet Ecuador commitments to the Kyoto Protocol

Full Text Available A total of 108 individuals from the Ecuadorian population from rural and urban places were analyzed for two CYP1A1 gene polymorphisms. The frequency of the val allele at codon 462 was 0.50, while the frequency of the Msp I restriction site, m2 allele at the T6235C position was 0.70. These polymorphisms in Ecuador have higher frequencies if we compare with others around the world, with the exception of some South American population in Brazil and Chile.

Ecuador still grappling over privatization as oil flow rises

1993-01-01

Ecuador continues to grapple with efforts to privatize its petroleum sector a year after disclosing its plans to withdraw from the Organization of Petroleum Exporting Countries. One of OPEC's smallest members, Ecuador last year said it would leave the group in March 1993, citing high membership costs and minimal benefits. Industry observers also noted at the time Ecuador's plans to sharply boost production this century might run afoul of its OPEC quota. Political controversy is stalling efforts to implement a new reform oriented hydrocarbon law in Ecuador that would open the country's petroleum sector to greater participation by foreign companies and privatize state petroleum companies, including Petroleos del Ecuador (Petroecuador). That comes even as foreign contractors' participation in Ecuador's upstream sector are making a significant contribution to boosting the country's oil production, which had remained flat for a number of years. The paper discusses the status of the new law, the controversy surrounding reforms, the master plan, environmental concerns, reserves and production, Petroecuador activity, planned pipeline work, service contracts, start-up of Oxy, details of Oxy development, and Elf's start-up

This paper examines the traditional use of medicinal plants in Loja province, Southern Ecuador.Two hundred fifteen plant species were collected, identified and their vernacular names and traditional uses recorded. This number of species indicates that the healers, market vendors and members of the public interviewed still have a very high knowledge of plants in their surroundings, which can be seen as a reflection of the knowledge of the population in general. However, the area represents only an outlier of the larger Northern Peruvian cultural area, where more than 500 species of plants are used medicinally, indicating that in Ecuador much of the original plant knowledge has already been lost.Most plant species registered are only used medicinally, and only a few species have any other use (construction, fodder, food). The highest number of species is used for the treatment of "magical" (psychosomatic) ailments (39 species), followed by respiratory disorders (34), problems of the urinary tract (28), Fever/Malaria (25), Rheumatism (23) and nervous system problems (20).

The main vectors of Chagas disease in Ecuador are Triatoma dimidiata and Rhodnius ecuadoriensis. The latter species occupies domestic and peridomestic habitats, as well as sylvatic ecotopes--particularly associated with Phytelephas aequatorialis palm trees--in the western coastal region of Ecuador. In the southern highlands, however, such palm tree habitats are uncommon, and sylvatic populations of R. ecuadoriensis have not previously been reported to date. This study was carried out in five rural communities in Loja Province in southern Ecuador, where manual triatomine searches were conducted in various sylvatic habitats. A total of 81 squirrel nests (Sciurus stramineus) and > 200 bird nests and other habitats were searched. One hundred three R. ecuadoriensis individuals were found in 11 squirrel nests (infestation index = 13.6%, density = 2 bugs per nest searched, crowding = 9.5 bugs per infested nest, colonization index = 72.7% of infested nests with nymphs). No triatomines were found in bird nests or other sylvatic habitats. The presence of sylvatic R. ecuadoriensis in the southern highlands of Ecuador has important implications for the long-term control of Chagas disease in the region because of the possibility of reinfestation of dwellings after insecticide-based control interventions.

Migration decisions, agrarian structure, and gender: the case of Ecuador.

Science.gov (United States)

Bravo-ureta, B E; Quiroga, R E; Brea, J A

1996-07-01

This article briefly reviews the literature on migration in Latin America and examines migration decision making in Ecuador. Aggregate data are obtained from the 1974 census of agriculture and population for cantones. Individual level data are obtained from the 1982 census of population. Migration refers to all census persons who recorded differences in their present and previous place of residence during 1974-82. Migration is modeled as dependent upon gender, age, education, marital status, income at origin and at destination, and population pressure or agrarian reform. Logistic model findings indicate that migration decisions are influenced by individual characteristics of migrants and contextual variables. Migration varied by gender. The results confirm Todaro's hypothesis that the probability of migrating is related to income differences between place of destination and origin, but only for males. Findings suggest that females migrate for primary reasons other than economic ones. The probability of migration was greater with increased levels of education. The decision to migrate was affected by quality of life differences, such as literacy rates and levels of urbanization. The probability of migration was reduced by the effects of land reform. Population pressure had a significant effect in increasing migration. The effects of land reform differ from findings in Mexico by William E. Cole and Richard D. Sanders. Land reforms were initiated in 1964 in Ecuador, but by 1974 there was still considerable inequality in land distribution and increased population pressure. Traditional haciendas were modernized, and peasants increased their dependency on non-farm income.

Ecuador, in its first full year outside the fold of the Organization of Petroleum Exporting Countries, stands poised for a significant expansion of production in the 1990s. While preparing for Ecuador's eventual withdrawal from OPEC last fall, the government since early summer 1992 has moved quickly to approve a number of key development projects. It was, perhaps, no coincidence that the most important conference on Ecuadorian petroleum prospects in recent years was timed to coincide with the government's public confirmation of the pullout. All foreign companies operating in Ecuador attended, with details disclosed of projects planned or under way. This article summarizes these projects and other key issues raised at the conference

Shadows of the colonial past--diverging plant use in Northern Peru and Southern Ecuador.

Bussmann, Rainer W; Sharon, Douglas

2009-02-02

This paper examines the traditional use of medicinal plants in Northern Peru and Southern Ecuador, with special focus on the Departments of Piura, Lambayeque, La Libertad, Cajamarca, and San Martin, and in Loja province, with special focus on the development since the early colonial period. Northern Peru represents the locus of the old Central Andean "Health Axis." The roots of traditional healing practices in this region go as far back as the Cupisnique culture early in the first millennium BC. Northern Peru and Southern Ecuador share the same cultural context and flora but show striking differences in plant use and traditional knowledge. Two hundred fifteen plant species used for medicinal purposes in Ecuador and 510 plant species used for medicinal purposes in Peru were collected, identified,. and their vernacular names, traditional uses, and applications recorded. This number of species indicates that the healers, market vendors, and members of the public interviewed in Peru still have a very high knowledge of plants in their surroundings, which can be seen as a reflection of the knowledge of the population in general. In Ecuador much of the original plant knowledge has already been lost. In Peru, 433 (85%) were Dicotyledons, 46 (9%) Monocotyledons, 21 (4%) Pteridophytes, and 5 (1%) Gymnosperms. Three species of Giartina (Algae) and one species of the Lichen genus Siphula were used. The families best represented were Asteraceae with 69 species, Fabaceae (35), Lamiaceae (25), and Solanaceae (21). Euphorbiaceae had 12 species, and Poaceae and Apiaceae each accounted for 11 species. In Ecuador the families best represented were Asteraceae (32 species), Euphorbiaceae, Lamiaceae, and Solanaceae (11 species each), and Apiaceae, Fabaceae, Lycopodiaceae (9 species each). One hundred eighty-two (85%) of the species used were Dicotyledons, 20 Monocotyledons (9.3%), 12 ferns (5.5%), and one unidentified lichen was used. Most of the plants used (83%) were native to Peru

A Primary Care System to Improve Health Care Efficiency: Lessons from Ecuador.

Aldulaimi, Sommer; Mora, Francisco E

2017-01-01

Ecuador is a country with few resources to spend on health care. Historically, Ecuador has struggled to find a model for health care that is efficient, effective, and available to all people in the country, even those in underserved and rural communities. In 2000, the Ecuador Ministry of Public Health implemented a new system of health care that used primary care as its platform. Since then, Ecuador has been able to increase its health care efficiency, increasing its ranking from 111 of 211 countries worldwide in 2000, to 20 of 211 countries in 2014. This article briefly reviews the new components of the system implemented in Ecuador and examines the tools used to accomplish this. The discussion also compares and contrasts the Ecuador and US systems, and identifies concepts and policies from Ecuador that could improve the US system. © Copyright 2017 by the American Board of Family Medicine.

Uranium exploration in Ecuador

International Nuclear Information System (INIS)

Severne, B.; Penaherrera, P.F.; Fiallos, V.S.

1981-01-01

The 600-km segment of the Andean Cordillera in Ecuador includes zones that can be correlated, geologically, with uranium districts elsewhere in the Andes. It is believed that these essentially unexplored zones have the potential for economic uranium mineralization. Exploration activity to date has been limited, although it has involved both geochemical and radiometric techniques to evaluate geological concepts. Minor uranium occurrences (with chemical analyses up to 100 ppm) have been encountered, which provide further incentive to commence large-scale systematic exploration. It is recognized that a very large exploration budget and considerable technical expertise will be required to ensure exploration success. Consequently, participation by groups of proven capability from other countries will be sought for Ecuador's national exploration programme. (author)

Estimating the benefits of preventing child maltreatment (CM) is essential for policy makers to determine whether there are significant returns on investment from interventions to prevent CM. The aim of this study was to estimate the benefits of preventing CM deaths in an Ecuadorian population, and to compare the results to a similar study in a US population. The study used the contingent valuation method to elicit respondents’ willingness to pay (WTP) for a 1 in 100,000 reduction in the risk of CM mortality. After adjusting for differences in purchasing power, the WTP to prevent the CM mortality risk reduction in the Ecuador population was $237 and the WTP for the same risk reduction in the US population was $175. In the pooled analysis, WTP for a reduction in CM mortality was significantly impacted by country (p = 0.03), history of CM (p = 0.007), payment mechanism (p Ecuador, may be better served by developing their own benefits estimates for use in future benefit-cost analyses of interventions designed to prevent CM.

The US Agency for International Development (AID) has discontinued its contraceptive social marketing project in Ecuador after 2 1/2 years without a sale. USAID had awarded a 3-year US$1.2 million grant to the program's contractor, the John Snow Public Health Group Inc. The project was run by Ecuador's national family planning association. This is only the 3rd time USAID has terminated a social marketing program since entering this field in 1973. Impediments to the program's operation included product price hikes and supply shortages as a result of teh inflation and currency devaluation in Ecuador in recent years. Government opposition to the sales of donated contraceptive supplies further set back the program. The name chosen for the condom distributed by the program, Liber, had to be changed since a company importing sanitary napkins was using the name Liberty and objected. The program's peculiar organizational structur is also considered to have played a role in the program's failure. Rather than having a single authority responsible for the program, a 2-headed organizational design was used. Program funds were controlled by the contractor, but the family planning organization managed day to day operations. Unified management has enabled programs in other countries to survive problems such as inflation, brand registration, and product and price approvals.

IAEA Completes Nuclear Security Advisory Mission in Ecuador

International Nuclear Information System (INIS)

2018-01-01

An International Atomic Energy Agency (IAEA) team of experts today completed a nuclear security advisory mission in Ecuador. The mission was carried out at the request of the Government of Ecuador. The scope of the two-week International Physical Protection Advisory Service (IPPAS) mission included the legislative and regulatory framework for the security of radioactive material, regulatory licensing, inspection and enforcement as well as coordination among authorities and other stakeholders involved in nuclear security. In September 2017, Ecuador ratified the 2005 Amendment to the Convention on the Physical Protection of Nuclear Material (CPPNM) and its incorporation into the nuclear security regime was also included in the scope of the mission. The IPPAS team carried out a number of visits, including to a steel company that uses gamma radiography, two hospitals, the National Polytechnic University and a company that transports radioactive material. In addition, the team visited a temporary storage facility for disused radioactive sources in Alóag, a town about 50 km south of the capital, Quito. The team observed that Ecuador is making efforts towards enhancing its national nuclear security regime. The team provided recommendations and suggestions to support Ecuador in enhancing and sustaining nuclear security. Good practices were identified that can serve as examples to other IAEA Member States to help strengthen their nuclear security activities.

BACKGROUND This study explored factors affecting the health and well being of recent refugees from Colombia in Ecuador. Data collection focused on how sending-country violence and structural violence in a new environment affect immigrant health vulnerability and risk behaviors. METHODS A qualitative approach included ethnographic observation, media content analysis, focus groups, and individual interviews with refugees (N=137). The focus groups (5) provided perspectives on the research domains by sex workers; drug users; male and female refugees; and service providers. RESULTS Social and economic marginalization are impacting the health and well being of this growing refugee population. Data illustrate how stigma and discrimination affect food and housing security, employment and health services, and shape vulnerabilities and health risks in a new receiving environment. DISCUSSION Widespread discrimination in Ecuador reflects fears, misunderstanding, and stereotypes about Colombian refugees. For this displaced population, the sequelae of violence, combined with survival needs and lack of support and protections, shape new risks to health and well-being. PMID:23377565

A large-scale study in Loja and El Oro Provinces, Ecuador, demonstrated that population-based treatment of human taeniasis with a low dose of praziquantel is feasible and effective for the short-term control of transmission of Taenia solium in hyperendemic areas. Chemotherapeutic intervention also effectively promoted local preventive measures and contributed greatly to the elaboration of a long-term control programme. PMID:2805217

Central Bank of Ecuador, 1927: among Dictatorship, Revolution and Crisis

Full Text Available On July 9th, 1925, a coup d’état overthrew the Ecuadorian government of the president Gonzalo S. Córdova. The Military Junta chose the new president, Dr. Isidro Ayora, who founded the Central Bank of Ecuador in 1927. The majority of historians emphasize the patriotic spirit of the military forces in order to eliminate the influence of private banks. Nonetheless, there is a less popular view of the Julian Revolution, which understands the coup d’état, and the foundation of the Central Bank of Ecuador, as the result of struggles between bankers due to controversies around currency emissions. The arguments behind the Julian Revolution were based on some economic facts. Even though real GDP did not decrease in any year from 1913 to 1927, there was a generalized perception of a critical economy due to the constant fluctuation in prices, the increasing of fiscal deficit, and the reduction of revenues from the trade balance. The economic crisis was a common factor in the urban areas, which represented less than half percent of the total population.

Cardiovascular risk assessment in elderly adults using SCORE OP model in a Latin American population: The experience from Ecuador.

Science.gov (United States)

Sisa, Ivan

2018-02-09

Cardiovascular disease (CVD) mortality is predicted to increase in Latin America countries due to their rapidly aging population. However, there is very little information about CVD risk assessment as a primary preventive measure in this high-risk population. We predicted the national risk of developing CVD in Ecuadorian elderly population using the Systematic COronary Risk Evaluation in Older Persons (SCORE OP) High and Low models by risk categories/CVD risk region in 2009. Data on national cardiovascular risk factors were obtained from the Encuesta sobre Salud, Bienestar y Envejecimiento. We computed the predicted 5-year risk of CVD risk and compared the extent of agreement and reclassification in stratifying high-risk individuals between SCORE OP High and Low models. Analyses were done by risk categories, CVD risk region, and sex. In 2009, based on SCORE OP Low model almost 42% of elderly adults living in Ecuador were at high risk of suffering CVD over a 5-year period. The extent of agreement between SCORE OP High and Low risk prediction models was moderate (Cohen's kappa test of 0.5), 34% of individuals approximately were reclassified into different risk categories and a third of the population would benefit from a pharmacologic intervention to reduce the CVD risk. Forty-two percent of elderly Ecuadorians were at high risk of suffering CVD over a 5-year period, indicating an urgent need to tailor primary preventive measures for this vulnerable and high-risk population.

Hashiguchi, Yoshihisa; Velez, Lenin N; Villegas, Nancy V; Mimori, Tatsuyuki; Gomez, Eduardo A L; Kato, Hirotomo

2017-02-01

This article reviews current knowledge about leishmaniases in Ecuador, proceeding from 1920, when the first human case was described, to the present, mainly focusing on the recent research events published. Regarding basic situations, it appears that 23 of Ecuador's 24 provinces have leishmaniasis-case reports. The disease is one of the mandatory notification infectious diseases in the country since 2005. All the 21,305 cases notified to the Ministry of Public Health, during the period from 2001 through 2014, were said to involve different clinical features of cutaneous leishmaniasis (CL) but not visceral (VL). Eight Leishmania species, L. (Viannia) guyanensis, L. (V.) panamensis, L. (V.) braziliensis, L. (Leishmania) mexicana, L. (L.) amazonensis, L. (L.) major-like, L. (V.) naiffiand L. (V.) lainsoni were characterized. The last two species were most recently reported from the Ecuadorian Amazon regions. Of the 73 Ecuadorian Lutzomyia species (43 man-biting species) recorded, only four, Lu. trapidoi, Lu. gomezi, Lu. ayacuchensis, and Lu. tortura were incriminated as vectors of the Leishmania parasites. Current knowledge on the reservoir hosts of Leishmania in Ecuador is extremely poor. Recently, in Ecuador different kinds of molecular techniques were developed for diagnosis and mass screening of the disease, employing various materials derived from patients and sand fly vectors. These are PCR-RFLP, colorimetric FTA-LAMP etc. Brief comments and recommendations were also given, for future research and control of leishmaniases in Ecuador. Copyright © 2016 Elsevier B.V.

Full Text Available In six Amazonian indigenous communities that call to their selves as membership of nación Kichwa, located in Pastaza province, in Ecuador, it is analyzed the process of inhabitation, population characteristics, how much the territory is enough for food requirements for the indigenous families, and their use of land, to determine important factors to improve strategies for local sustainable development. It is considered important because Ecuador has constitutional protection for plural ethnicity and it is looking for improving a new productivity matrix that let down extraction and contamination and raise another matrix based on knowledge and richness from natural renewable resources. Survey used statistics information, qualitative analysis around reality in process, participant research, documentary analysis, oral history and surveys to leadership and family`s chiefs. Results confirm that communities hold standing their identity and knowledge systems of the Amazonian environment, whose conservation they need. Those are factors to be included in local development strategies that let people become safe from effects of extractives activities that are dangerous for culture and environment, in the geographic and biological diversity of the high Ecuadorian Amazonia.

Offshore Aquaculture Development in Ecuador

Julio López Alvarado

2016-03-01

Full Text Available Ecuador has a long tradition in aquaculture, mainly related to the cultivation of shrimp and tilapia in earthen ponds. Land-based production methods have a large environmental, economic and social impact due to the extensive use of land and its effects on the ecosystems. In order to increase the production of fish without further land use and with a lower environmental impact, a good alternative is the culture of fish in floating cages, adopting technologies used successfully in many other countries. This article analyses the current situation of offshore aquaculture (the production of fish and other aquatic organisms in the open sea in Ecuador, and the prospects for the future of this sector in the country.

Sending-country violence and receiving-country discrimination: effects on the health of Colombian refugees in Ecuador.

Shedlin, Michele G; Decena, Carlos U; Noboa, Hugo; Betancourt, Óscar

2014-02-01

This study explored factors affecting the health and well being of recent refugees from Colombia in Ecuador. Data collection focused on how sending-country violence and structural violence in a new environment affect immigrant health vulnerability and risk behaviors. A qualitative approach included ethnographic observation, media content analysis, focus groups, and individual interviews with refugees (N = 137). The focus groups (5) provided perspectives on the research domains by sex workers; drug users; male and female refugees; and service providers. Social and economic marginalization are impacting the health and well being of this growing refugee population. Data illustrate how stigma and discrimination affect food and housing security, employment and health services, and shape vulnerabilities and health risks in a new receiving environment. Widespread discrimination in Ecuador reflects fears, misunderstanding, and stereotypes about Colombian refugees. For this displaced population, the sequelae of violence, combined with survival needs and lack of support and protections, shape new risks to health and well-being.

Ortiz-Prado, Esteban; Armijos, Luciana; Iturralde, Ana Lucia

2015-05-01

To describe the demographic, risk factor, occupational, and morbidity and mortality characteristics of burns in adults in Ecuador using national data. These data are from the only specialized public hospital in Ecuador that has a 12-bed burn unit. The National Institute of Statistics and Census provided data from the burn unit of the Hospital Eugenio Espejo, in Quito. Three different datasets pertaining to burn deaths, burn unit inpatient admissions, and hospital discharge were analyzed. Patients who died or were discharged before entering the burn unit were not included in this analysis. During the 10-year period, 1106 patients were admitted to the burn unit, men represent 69.37% with 768 cases and women represent 30.62% with 337 patients; the number of patients per year was on average 123 cases; the average age was 33-34 years old, with a range between 16 and 96 years old. Heat (thermal) burns represent 65.78% followed by electrical with 30.53%, friction burns with 2.06%, and chemical burns with 1.62%. Domestic methane gas was the most frequent agent causing thermal burns and the most affected occupational groups are construction workers and people who stay at home. The overall mortality is 10.2% and the average length of stay was 23 days. Thermal burns are more frequent than any other cause of burns. Electrical burns are more frequent in Ecuador than anywhere else according to our research, meaning that control and prevention of workplace safety, urban planning, and home safety are scarce. The most affected groups are those dedicated to labor work. Finally, mortality in hospitalized patient is higher when compared with developed countries. Copyright © 2014 Elsevier Ltd and ISBI.

Percepciones hemisfericas sobre la crisis colombiana: el caso de Ecuador.

Directory of Open Access Journals (Sweden)

Pablo Andrade A.

2004-07-01

Full Text Available The essay describes the securitization of Ecuador's policy regarding the Colombian conflict. The author argues that since 1999, distinct governments have adopted a policy that treats the Colombian conflict as a threat to the existential survival of Ecuador. In the first part of the essay, the author discusses the assumptions underlying this policy in light of the available empirical evidence on the effects of the armed conflict over the past five years. The second part deals with the process of securitization itself, illustrating the effects of perceptions of threat on the part of Ecuador's decision-makers, in particular the Armed Forces. The last two sections examine the links existing between Ecuador's policy and the regional interests of the United States, and the effects of the securitization process and its likely continuation in the future.

Ecuador: una democracia inestable

Full Text Available En 1979, tras una década de dictaduras militares, se inició la fase constitucional más larga en la historia del Ecuador. Ésta se levantó sobre las herencias del pasado y se caracterizó, de manera fundamental, por el tránsito desde un modelo estatal-desarrollista hacia uno de tipo empresarial, por el aparecimiento de nuevos agentes sociales, el multipartidismo político, la regionalización nacional, la presencia multicultural y la inserción del país en nuevas relaciones internacionales. Pero esos procesos trajeron como consecuencias centrales: la edificación de una economía inequitativa, una sociedad tensionada, la desestructuración institucional, la precarización del trabajo y la debilidad con la que la nación ha enfrentado el nuevo mundo unipolar. Todo ello ha configurado un cuadro de riesgos para la incipiente democracia. El Ecuador contemporáneo tiene, por tanto, una serie de desafíos económicos, sociales y políticos para escapar a la inestabilidad que ha acompañado a la construcción de su modernización democrática.___________________ABSTRACT:In 1979, after one decade of military dictatorships, the longest constitutional phase in the history of Ecuador was initiated. It was built upon the inheritance of the past and can be fundamentally characterized by the transition from a model that focused on the state as developing the economy (State-model to a model that focused on private business (enterprise-model. The appearance of new social agents, a multiparty system, national regionalization, multicultural presence and the country´s new international relationships are processes which show some important consequences: the establishment of an unequal economy, a society under tension, the breakdown of institutional structures, the vulnerability of working conditions and the weakness with which the nation faced the new polarized world. All this might put into danger this incipient democracy. And this is why Ecuador in these

To shed light on the epidemiology of ascariasis in Ecuador and Zanzibar, 177 adult worms retrieved by chemo-expulsion from either people or pigs were collected, measured and subjected to polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis of the ribosomal internal transcribed spacer (ITS) region. Upon double digestion with RsaI and HaeIII, PCR-RFLP analysis revealed the presence of A. lumbricoides in people and A. suum in pigs in Ecuador. In contrast, while there are no pigs on Zanzibar, of the 56 worms obtained from people, one was genotyped as A. suum. No additional genetic variation was detected upon further PCR-RFLP analysis with several other restriction enzymes. Upon measurement, worm mass and length differed by location and by species, A. suum being lighter and longer. While there is no evidence to suggest zoonotic transmission in Ecuador, an enduring historical signature of previous zoonotic transmission remains on Zanzibar.

Burden of disease studies intend to improve public health decision-making and to measure social and economic impact in population. The objective of this study was to describe the burden of acute respiratory infections (ARI) in Ecuador between 2011 and 2015. Five-year period morbidity and mortality data available from national agencies of statistics was analyzed to estimate the burden of disease attributable to acute respiratory infections. Cases and deaths registered were grouped according to their ICD-10 code into three diagnostic groups: Acute upper respiratory infections (J00-J06), Influenza and pneumonia (J09-J18), and Bronchitis and other acute lower respiratory infections (J20-J22, J85, J86). Disability-adjusted life years stratified by diagnostic and age group were calculated using the "DALY" package for R. The productivity loss in monetary terms was estimated using the human capital method. Over the 5-year period studied there were a total of 14.84 million cases of acute respiratory infections, with 17 757 deaths reported (0.12%). The yearly burden of disease ranged between 98 944 to 118 651 disability-adjusted life years, with an estimated average loss of productivity of US$152.16 million (±19.6) per year. Approximately 99% of the burden can be attributed to years life lost due to premature mortality in population under 5 years old and over 60 years-old. The burden of acute respiratory infections remained steady during the analyzed period. Evidence-based prevention and control policies to tackle acute respiratory infections in Ecuador should focus on the population at extreme ages of life.

To assess the epidemiology of acromegaly in the city of Guayaquil, Ecuador, and to compare our results to those reported in the literature. An analysis was made of retrospective and prospective data from all patients with acromegaly attending endocrinology clinics at the 4 main hospitals of the public health network of Guayaquil from January 2000 to December 2014. Age at diagnosis, estimated delay in diagnosis, imaging studies of pituitary gland, basal growth hormone (GH) level, GH after an oral glucose tolerance test (OGTT-GH), and serum levels of insulin-like growth factor 1 (IGF-1) were recorded. Incidence and prevalence of the disease were estimated using information from the 2010 census of population and housing. Forty-eight cases were recorded in the study period in 17 males (35.4%) and 31 females (64.5%); M/F ratio=1.8:1. Mean age at diagnosis was 47.3±16.8 years (range 18-86). Delay in diagnosis was 7.3±6.3 years (range 1-30). Mean age at diagnosis was 47.9±18.2 years in males and 46.3±15.8 years in females. Delay in diagnosis was 10.2±7.9 and 5.7±3.9 years in males and females, respectively. Prevalence of acromegaly is 18.7 cases per million inhabitants, and incidence of acromegaly 1.3 cases per million people per year. Acromegaly predominates in females, and is diagnosed in the fourth decade with a delay of approximately 8 years, usually even longer in males. Incidence and prevalence are lower than reported in international series. The disease is underdiagnosed and underreported in Ecuador. Copyright © 2016 SEEN. Publicado por Elsevier España, S.L.U.

2014-01-01

Full Text Available Objectives. To estimate the prevalence and determinants of fall-related injuries in the previous year among adults aged 60 years or older in Ecuador. Methods. The prevalence of fall-related injuries was estimated using cross-sectional data from the first national survey of Health, Wellbeing, and Aging study. Logistic regression models were used to examine the associations between participants’ demographic characteristics and fall-related injuries. Results. Of 5,227 participants with a mean age of 72.6 years, 11.4% (95% CI, 10.3%–12.7% reported a fall-related injury in Ecuador, representing an estimated 136,000 adults aged 60 years or older. Fall-related injuries were more frequently reported among older adults residing in the most urbanized and populated provinces of the country. After controlling for potential confounders, self-reported race as Indigenous (OR 2.2; 95% CI, 2.11–2.31, drinking alcohol regularly (OR 2.54; 95% CI, 2.46–2.63, subjects with greater number of comorbid conditions (OR 2.03; 95% CI, 1.97–2.08, and urinary incontinence (OR 1.83; 95% CI, 1.79–1.87 were factors independently associated with increased odds of sustaining fall-related injuries. Conclusions. Fall-related injuries represent a considerable burden for older adults in Ecuador. The present findings may assist public health authorities to implement fall prevention programs among subjects at higher risk for this type of injury.

Human brucellosis in northwest Ecuador: typifying Brucella spp., seroprevalence, and associated risk factors.

Human brucellosis in Ecuador is underreported and based only on passive surveillance. Since 2008, brucellosis was removed from the list of communicable diseases in the country. Until now, the true human brucellosis picture has not yet been determined. The aim of this study was to determine the seroprevalence of the disease, identify risk factors associated with brucellosis seropositivity in humans, and isolate circulating strains of Brucella spp. in the northwestern part of Ecuador. Between 2006 and 2008, a large transect survey was conducted, based on blood sampling of people from the northwestern part of Ecuador (n=3733) together with an epidemiological inquiry. On the basis of three diagnostic tests used in parallel, the overall seroprevalence was estimated as 1.88% (95% confidence interval [CI] 1.48-2.38). Based on a multivariable random effects logistic regression analysis, the main risk factors associated with human brucellosis seropositivity were contact with livestock (odds ratio [OR]=3.0; CI 1.25-7.08), consumption of fetus and placenta (OR=2.5; CI 1.18-5.22), and involvement in activities at risk for brucellosis infection (OR=1.8; CI 1.00-3.35). Noticeable variation in brucellosis seropositivity among humans within cantons was observed. The circulating strain was Brucella abortus biotype 4. This study emphasized that contact with livestock, consumption of fetus and placenta, and occupational hazard group were all significant risk factors for the transmission of brucellosis among individuals in the northwestern part of Ecuador. Alongside encouraging the launching of educational campaigns against brucellosis, especially in rural areas where 36% of the population lives, controlling this zoonotic disease in animals will directly benefit its prevention in humans, especially because there is no safe and efficacious vaccine against brucellosis in humans.

Geodynamic control of the chemical composition of Tertiary continental arc magmas of Ecuador?

International Nuclear Information System (INIS)

Chiaradia, M.; Fontbote, L

2001-01-01

Whereas an abundant literature has been produced on the Tertiary magmatism of the Central Andes, no comparable studies exist for the Tertiary continental magmatism of the Northern Andes in general and of Ecuador in particular. In this contribution we present the first extensive data on lead and strontium isotopes of Paleocene to Pliocene magmatic rocks of Ecuador together with their major, trace and rare earth element geochemistry. The main interest of carrying out a geochemical and isotopic investigation on the magmatism of Ecuador is that, different from the Central Andes, Ecuador consists of several accreted terranes both of continental and oceanic affinity. The fragmented nature of the recently assembled crust of Ecuador, composed of lithologies such as Paleozoic schists, Triassic anatexites, and Jurassic metabasalts, could have variably affected the chemistry of the Ecuadorian magmas (au)

Zurita, Jeannete; Barba, Pedro; Ortega-Paredes, David; Mora, Marcelo; Rivadeneira, Sebastián

The spread of pandemic Staphylococcus aureus clones, mainly methicillin-resistant S. aureus (MRSA), must be kept under surveillance to assemble an accurate, local epidemiological analysis. In Ecuador, the prevalence of the USA300 Latin American variant clone (USA300-LV) is well known; however, there is little information about other circulating clones. The aim of this work was to identify the sequence types (ST) using a Multiple-Locus Variable number tandem repeat Analysis 14-locus genotyping approach. We analyzed 132 S. aureus strains that were recovered from 2005 to 2013 and isolated in several clinical settings in Quito, Ecuador. MRSA isolates composed 46.97% (62/132) of the study population. Within MRSA, 37 isolates were related to the USA300-LV clone (ST8-MRSA-IV, Panton-Valentine Leukocidin [PVL] +) and 10 were related to the Brazilian clone (ST239-MRSA-III, PVL-). Additionally, two isolates (ST5-MRSA-II, PVL-) were related to the New York/Japan clone. One isolate was related to the Pediatric clone (ST5-MRSA-IV, PVL-), one isolate (ST45-MRSA-II, PVL-) was related to the USA600 clone, and one (ST22-MRSA-IV, PVL-) was related to the epidemic UK-EMRSA-15 clone. Moreover, the most prevalent MSSA sequence types were ST8 (11 isolates), ST45 (8 isolates), ST30 (8 isolates), ST5 (7 isolates) and ST22 (6 isolates). Additionally, we found one isolate that was related to the livestock associated S. aureus clone ST398. We conclude that in addition to the high prevalence of clone LV-ST8-MRSA-IV, other epidemic clones are circulating in Quito, such as the Brazilian, Pediatric and New York/Japan clones. The USA600 and UK-EMRSA-15 clones, which were not previously described in Ecuador, were also found. Moreover, we found evidence of the presence of the livestock associated clone ST398 in a hospital environment. Copyright © 2016 Sociedade Brasileira de Infectologia.

Exploration and development at crossroads in Ecuador

International Nuclear Information System (INIS)

Anon.

1992-01-01

This paper reports that Ecuador's oil and gas sector has reached a pivotal point in its history. After several years of fairly brisk activity, foreign operators recently began scaling back exploration in Ecuador. They cited results that haven't met expectations and persistent delays in obtaining approval by state owned Petroecuador for development of reserves that have been discovered. Foreign oil companies had anticipated the pace of development would accelerate in Ecuador in early 1992, but major projects generally remained in limbo for most of this year. At presstime, however, there were signs of an encouraging follow-through in promised reforms in the permitting process. Petroecuador in April-May approved two of those projects and a third in June. Of the 13 oil companies or groups that had signed exploration contracts with the state oil company since 1985, several companies have terminated their operations in the country, and only one company, Oryx Energy Co., Dallas, is producing a small volume of oil. Two other companies have been negotiating exploration rights for about 2 years, with contracts yet to be signed

Full Text Available The tomato leafminer, Tuta absoluta (Meyrick (Lepidoptera: Gelechiidae, is a economically important pest of processed and fresh tomatoes, both in greenhouses and open field crops. Currently, the pest threatens other cultivated solanaceous plants such as eggplant and potato. In this article we review pheromone control strategies for species-specific and environmentally safe management of the tomato leafminer, Tuta absoluta (Lepidoptera: Gelechiidae. This insect pest originates from South America and is now considered to be one of the most damaging invasive pests of tomatoes in the Mediterranean Basin countries of Europe and North Africa. In this article we describestrategies used to control T. absoluta including pest detection and population monitoring. Monitoring of Tuta absoluta was carried out in Imbabura Province in Ecuador. The parameters of using the pheromone traps Delta VI are described.

The Vital Minimum Amount of Drinking Water Required in Ecuador

Directory of Open Access Journals (Sweden)

Andrés Martínez Moscoso

2018-02-01

Full Text Available In 2017, the government of Ecuador established the minimum quantity of water required to be provided for free by drinking water utilities. Ecuador recognized the access to water as a fundamental human right because it guarantees the good living, known as “Sumak kawsay”, an indigenous Andean concept, in the Ecuadorian Constitution. This represents a novel approach to water rights in the world, as it is the first attempt to establish a minimum quantity of water under a constitutional guarantee by legislation, rather than regulation or judicial decision. However, this novel legislative approach raises the question of how this minimum amount of free water will impact the most vulnerable members of the Ecuadorian community. This paper provides the results of the first comprehensive research of the minimum required water provision in Ecuador. In order to measure the impact on the income of households, we built a methodology integrating: doctrinaire analyses, normative studies, and economic analyses. According to the Ecuadorian legislation, over-consumption of raw water generates additional costs that must be paid by water companies to the central government. In that regard, there is an inevitable relationship between the efficiency of the service and those additional costs. Efficiency, on this case, is the capacity of water companies (public or private to provide water services at an adequate price, observing the following parameters: quantity, quality and sufficiency. Our research found that with this legislation in three Ecuadorian local governments (Cuenca, Gualaceo and Suscal, the most vulnerable households (i.e., low-income and/or indigenous households will be affected the most. This means that and those families will spend the most part of their income on water services otherwise they would have to reduce their water consumption.

To estimate smoking prevalence by gender, describe patterns of cigarette use, and identify predictors of current smoking in reproductive-age adults in four Latin American countries. Self-reported smoking was examined using data from Reproductive Health Surveys of women aged 15-49 years in Ecuador (2004), El Salvador (2002-2003), Guatemala (2002), and Honduras (2001), and of men aged 15-59 years in El Salvador, Guatemala, and Honduras for the same years. Current smoking was assessed by demographic characteristics, and independent associations were examined using logistic regression. Data were weighted to be nationally representative of households with reproductive-age women and men. Current smoking prevalence ranged from 2.6% (Guatemala) to 13.1% (Ecuador) for women and from 23.1% (Guatemala) to 34.9% (El Salvador) for men. In Ecuador, 67.6% of female smokers were non-daily users; in other countries, daily use was more prevalent than non-daily use for both men and women. In daily users, the median number of cigarettes smoked per day ranged from 1.9 (Ecuador, Honduras) to 2.3 (Guatemala) for women and from 2.1 (Guatemala) to 3.6 (Honduras) for men. In bivariate analysis, smoking prevalence in all countries was highest in women who lived in urban areas, were previously married, and/or had high socioeconomic status. Risk factors for smoking varied by country and gender. National tobacco control programs in these countries should aggressively target high-risk populations (reproductive-age men) and maintain low prevalence in low-risk populations (reproductive-age women). More research is needed to understand addiction patterns in non-daily smokers.

Los Derechos Humanos en Ecuador: una visión pesimista

Directory of Open Access Journals (Sweden)

Fredy RIVERA VÉLEZ

2009-11-01

Full Text Available RESUMEN: La reivindicación de los derechos humanos en Ecuador tiene que ver con la percepción generalizada que se tiene de esos derechos y de la idiosincrasia de la sociedad. Para el autor, la vulneración de los derechos humanos no sólo proviene del Estado, sino también concierne a los ciudadanos. Así, la cultura política y social del Ecuador ha estado permeada por el clientelismo, sistema que ha generado relaciones de dependencia y dominación que confirman el poder en un sector, que impiden el desarrollo de la ciudadanía y hacen imposible la democratización del poder. La legalidad está al margen de la vida política y social, lo que permite que reglas mínimas como son los derechos humanos sean desconocidos y la sociedad no se plantee su reivindicación. La cultura política y social es fundamental para entender el escepticismo y la entrega a normas de conducta contrarias al ejercicio de la ciudadanía y en últimas a la consolidación de la dignidad.ABSTRACT: The reivindication of human rights in Ecuadror relates to the generalized vision of the population regarding those rights. For the author, the transgression of these rights does not only stem from the state, but also from the citizens. Social and political culture in Ecuador has been characterized by clientelism, dependence, and domination. This cultural system hampers the development of citizenship and makes democratization impossible. Social and political life is not affected by the rule of law, which prevents human rights from being widely known and demanded. Social and political culture is crucial to understand the scepticism and the prevalence of behaviors which are inimical to citizenship and human dignity.

Use of spatial capture–recapture to estimate density of Andean bears in northern Ecuador

Molina, Santiago; Fuller, Angela K.; Morin, Dana J.; Royle, J. Andrew

2017-01-01

The Andean bear (Tremarctos ornatus) is the only extant species of bear in South America and is considered threatened across its range and endangered in Ecuador. Habitat loss and fragmentation is considered a critical threat to the species, and there is a lack of knowledge regarding its distribution and abundance. The species is thought to occur at low densities, making field studies designed to estimate abundance or density challenging. We conducted a pilot camera-trap study to estimate Andean bear density in a recently identified population of Andean bears northwest of Quito, Ecuador, during 2012. We compared 12 candidate spatial capture–recapture models including covariates on encounter probability and density and estimated a density of 7.45 bears/100 km2 within the region. In addition, we estimated that approximately 40 bears used a recently named Andean bear corridor established by the Secretary of Environment, and we produced a density map for this area. Use of a rub-post with vanilla scent attractant allowed us to capture numerous photographs for each event, improving our ability to identify individual bears by unique facial markings. This study provides the first empirically derived density estimate for Andean bears in Ecuador and should provide direction for future landscape-scale studies interested in conservation initiatives requiring spatially explicit estimates of density.

2017-08-01

To evaluate the prevalence of hyperglycemia and dyslipidemia in the population of Isabela, Galápagos, Ecuador, across gender and age (above or below 50). In this population-based retrospective cross-sectional study among individuals in Isabela, Galápagos, Ecuador, demographic and metabolic factors were evaluated based on World Health Organization (WHO) Global Guidelines. The population overall exceeded the WHO guidelines for cardiovascular health. As to be expected, there was significance in the trend of increasing dyslipidemia and hyperglycemia with age except postprandial glucose. In those individuals below the age of 50, 8.0%, 49% and 26% had hyperglycemia, hypercholesterolemia and hypertriglyceridemia, respectively. However, in those above 50, they measured 24%, 68% and 36% respectively, showing a significant increase. Hyperglycemia and dyslipidemia appear to be prevalent in Isabela, Galápagos, Ecuador and this pilot study supports further research into metabolic syndrome and diabetes. Such data may help in healthcare planning and screening to ensure not only timely diagnosis, but prevention. The limitations of this data illustrate modalities that data collection can be improved, such as having a linked clinical history to the data itself and better patient follow up for such entities as post prandial glucose, for example. However, this pilot study presents a starting point for future directions of research, such as ascertaining prevalence of diabetes type II, metabolic syndrome and cardiovascular disease.

1992-01-01

This paper reports that the Organization of Petroleum Exporting Countries, which has agreed to maintain its present combined production of 24.2 million b/d of oil in the fourth quarter, will soon see the first pullout of a member. The 13 member group will shrink to 12, probably in November, when Ecuador withdraws. Ecuador President Sixto Duran Ballen issued notice of the pullout Sept. 17, a little more than 1 month after he took office. Ecuador, strapped for cash, wants to save OPEC membership dues reported to be $2-3 million/year. It plans to remain an associate member, although it wasn't immediately clear what that means. No other countries are regarded as associate members

Molecular epidemiology at the community level has an important guiding role in zoonotic disease control programmes where genetic markers are suitably variable to unravel the dynamics of local transmission. We evaluated the molecular diversity of Trypanosoma cruzi, the etiological agent of Chagas disease, in southern Ecuador (Loja Province). This kinetoplastid parasite has traditionally been a paradigm for clonal population structure in pathogenic organisms. However, the presence of naturally occurring hybrids, mitochondrial introgression, and evidence of genetic exchange in the laboratory question this dogma. Eighty-one parasite isolates from domiciliary, peridomiciliary, and sylvatic triatomines and mammals were genotyped across 10 variable microsatellite loci. Two discrete parasite populations were defined: one predominantly composed of isolates from domestic and peridomestic foci, and another predominantly composed of isolates from sylvatic foci. Spatial genetic variation was absent from the former, suggesting rapid parasite dispersal across our study area. Furthermore, linkage equilibrium between loci, Hardy-Weinberg allele frequencies at individual loci, and a lack of repeated genotypes are indicative of frequent genetic exchange among individuals in the domestic/peridomestic population. These data represent novel population-level evidence of an extant capacity for sex among natural cycles of T. cruzi transmission. As such they have dramatic implications for our understanding of the fundamental genetics of this parasite. Our data also elucidate local disease transmission, whereby passive anthropogenic domestic mammal and triatomine dispersal across our study area is likely to account for the rapid domestic/peridomestic spread of the parasite. Finally we discuss how this, and the observed subdivision between sympatric sylvatic and domestic/peridomestic foci, can inform efforts at Chagas disease control in Ecuador.

2015-01-01

In the highlands of southern Colombia and northern Ecuador, soils developed on volcanic ash deposits have specific properties: high water retention, high hydraulic conductivity and high carbon (C) contents. The main role of the soils is to regulate the water available for the dense population living in the valleys. Soil properties and land use depend on their altitudes. Any important modification of land-use change has a serious effect on soil properties and consequently the ecosystem propert...

This first approach has as a problem What does Loja provides, that distinguish from the rest of the provinces of Ecuador in the musical field, to be considered its capital? This first delivery aims to build a framework of computer concepts that open up posterity to a field of research on music and that translate into policies, plans and programs that empower it. They develop three concepts derived from the thesis: the power to construct music that refers to the generic and specific competences in different instruments and genres, the amount of music that is produced and the human talent in musical formation that is developed in Loja. Empirical evidence is collected to corroborate or reject the hypothesis: Loja is the musical capital of Ecuador. Data are collected on musical skills and compared at the global level, as well as music production and music training scenarios. At the end the hypothesis is checked. The task of the Lojanos is to innovate the capital. Keywords: Music, musical competitions, musical talent in training, amount of music, musicalperformance, musical instrument, songs.

Laron-type dwarfism, which is characterized by the clinical appearance of isolated growth hormone deficiency with elevated serum levels of growth hormone and decreased serum levels of insulin-like growth factor I (IGF-I), has been described in approximately 50 patients. This condition is caused by a deficiency of the cellular receptor for growth hormone, and it is transmitted as an autosomal recessive trait, as indicated by an equal sex distribution and a high rate of consanguinity in affected families. We studied 20 patients (19 females and 1 male, 2 to 49 years of age), from an inbred Spanish population in southern Ecuador, who had the clinical features of Laron-type dwarfism. Seventeen patients were members of two large pedigrees. Among the 13 affected sibships, there were 19 affected and 24 unaffected female siblings and 1 affected and 21 unaffected male siblings. The patients' heights ranged from 10.0 to 6.7 SD below the normal mean height for age in the United States. In addition to the previously described features, 15 patients had limited elbow extensibility, all had blue scleras, affected adults had relatively short extremities, and all four affected women over 30 years of age had hip degeneration. Basal serum concentrations of growth hormone were elevated in all affected children (30 to 160 micrograms per liter) and normal to moderately elevated in the adults. The serum level of growth hormone-binding protein ranged from 1 to 30 percent of normal; IGF-I concentrations were low--less than or equal to 7 micrograms per liter in the children and less than or equal to 66 micrograms per liter in the adults (normal for Ecuadorean women, 98 to 238). Serum levels of IGF-II and growth hormone-dependent IGF-binding protein-3 were also low. We describe an inbred population with a high incidence of growth hormone-receptor deficiency resulting in a clinical picture resembling Laron-type dwarfism but differing principally in showing a marked predominance of affected

Genetic and phenotypic diversity of Rhizobium isolates from Southern Ecuador

Roldán Torres-Gutiérrez

Full Text Available ABSTRACT Rhizobium-legume symbioses play relevant roles in agriculture but have not been well studied in Ecuador. The aim of this study was to characterize the genetic and phenotypic diversity of Rhizobium isolates associated with Phaseolus vulgaris from southern Ecuador. Morpho-cultural characterization, biochemical tests and physiological analyses were conducted to authenticate and determine the diversity of bacteria Rhizobium-like isolates. The genetic diversity of the isolates was determined by molecular techniques, which consisted of bacteria DNA extraction and amplification and sequencing of the 16S rRNA gene. The nodulation parameters and nitrogen fixation for P. vulgaris under greenhouse conditions were also assessed to determine the phenotypic diversity among isolates. Furthermore, bacteria indole-acetic-acid production was evaluated by the colorimetric method. Morpho-cultural and biochemical characteristic assessments demonstrated that Rhizobium-like bacteria was associated with the P. vulgaris nodules. The diversity among the isolates, as determined by physiological analyses, revealed the potential of several isolates to grow at different pH values, salinity conditions and temperatures. Partial sequencing of the 16S rRNA gene identified the Rhizobium genus in every sampling site. From a total of 20 aligned sequences, nine species of Rhizobium were identified. Nodule formation and biomass, as well as nitrogen fixation, showed an increase in plant phenotypic parameters, which could be influenced by IAA production, especially for the strains R. mesoamericanum NAM1 and R. leguminosarum bv. viciae COL6. These results demonstrated the efficiency of native symbiotic diazotrophic strains inoculants for legume production. This work can serve as the basis for additional studies of native Rhizobium strains and to help spread the use of biofertilizers in Ecuadorian fields.

Clausen, Drew; Wade, Richard A.; Kopparapu, Ravi Kumar; O'Shaughnessy, Richard

2012-01-01

Binaries that contain a hot subdwarf (sdB) star and a main-sequence companion may have interacted in the past. This binary population has historically helped determine our understanding of binary stellar evolution. We have computed a grid of binary population synthesis models using different assumptions about the minimum core mass for helium ignition, the envelope binding energy, the common-envelope ejection efficiency, the amount of mass and angular momentum lost during stable mass transfer, and the criteria for stable mass transfer on the red giant branch and in the Hertzsprung gap. These parameters separately and together can significantly change the entire predicted population of sdBs. Nonetheless, several different parameter sets can reproduce the observed subpopulation of sdB + white dwarf and sdB + M dwarf binaries, which has been used to constrain these parameters in previous studies. The period distribution of sdB + early F dwarf binaries offers a better test of different mass transfer scenarios for stars that fill their Roche lobes on the red giant branch.

Diversity and distribution of the Caddisflies (Insecta: Trichoptera of Ecuador

Directory of Open Access Journals (Sweden)

Blanca Ríos-Touma

2017-01-01

Full Text Available Background Aquatic insects and other freshwater animals are some of the most threatened forms of life on Earth. Caddisflies (Trichoptera are highly biodiverse in the Neotropics and occupy a wide variety of freshwater habitats. In Andean countries, including Ecuador, knowledge of the aquatic biota is limited, and there is a great need for baseline data on the species found in these countries. Here we present the first list of Trichoptera known from Ecuador, a country that harbors two global biodiversity “hotspots.” Methods We conducted a literature review of species previously reported from Ecuador and supplemented these data with material we collected during five recent field inventories from about 40 localities spanning both hotspots. Using species presence data for each Ecuadorian province, we calculated the CHAO 2 species estimator to obtain the minimum species richness for the country. Results We recorded 310 species, including 48 new records from our own field inventories for the country. CHAO 2 calculations showed that only 54% of the species have been found. Hydroptilidae and Hydropsychidae were the most species rich families. We report the family Xiphocentronidae for the first time from Ecuador as well as several new records of genera from different families. Discussion As in the neighboring Andean countries of Colombia and Peru, it is common to find undescribed species of caddisflies. There are vast areas of Ecuador and the northern Andes that are completely unexplored, and we expect that hundreds of new species are yet to be discovered.

2015-04-01

Natural resources are deteriorating very rapidly in the Gulf of Guayaquil and the area of influence in the Guayas Basin due to human activity. Specific problems are generated by the mismanagement of the aquaculture industry affecting the traditional agricultural sectors: rice, banana, sugarcane, cocoa, coffee, and soya also studied, and by human and industrial settlements. The development of industrial activities such as aquaculture (shrimp building for shrimp farming in ponds) and agriculture, have increasingly contributed to the generation of waste, degrading and potentially toxic elements in high concentrations, which can have adverse effects on organisms in the ecosystems, in the health of the population and damage the ecological and environmental balance. The productive Guayas ecosystem, consists of three interrelated ecosystems, the Gulf of Guayaquil, the Guayas River estuary and the Guayas Basin buffer. The objective of this study was to evaluate the environmental quality of the productive Guayas ecosystem (Ecuador), through operational and specific objectives: 1) Draw up the transition coastal zone in the Gulf of Guayaquil, 2) Set temporal spatial variability of soil salinity in wetlands rice, Lower Guayas Basin, 3) evaluate the heavy metals in wetland rice in the Lower Basin of Guayas. The physical and chemical parameters of the soils have been studied. These are indicators of environmental quality. The multivariate statistical method showed the relations of similarities and dissimilarities between variables and parameter studies as stable. Moreover, the boundaries of coastal transition areas, temporal spatial variability of soil salinity and heavy metals in rice cultivation in the Lower Basin of Guayas were researched. The sequential studies included and discussed represent a broad framework of fundamental issues that has been valued as a basic component of the productive Guayas ecosystem. They are determinants of the environmental quality of the Guayas

Full Text Available Objectives: The objectives of this report were to document the potential presence of Mayaro virus infection in Ecuador and to examine potential risk factors for Mayaro virus infection among the personnel of a military garrison in the Amazonian rainforest. Materials and Methods: The study population consisted of the personnel of a garrison located in the Ecuadorian Amazonian rainforest. The cross-sectional study employed interviews and seroepidemiological methods. Humoral immune response to Mayaro virus infection was assessed by evaluating IgM- and IgG-specific antibodies using ELISA. Results: Of 338 subjects studied, 174 were from the Coastal zone of Ecuador, 73 from Andean zone, and 91 were native to the Amazonian rainforest. Seroprevalence of Mayaro virus infection was more than 20 times higher among Amazonian natives (46% than among subjects born in other areas (2%. Conclusions: Age and hunting in the rainforest were significant predictors of Mayaro virus infection overall and among Amazonian natives. The results provide the first demonstration of the potential presence of Mayaro virus infection in Ecuador and a systematic evaluation of risk factors for the transmission of this alphavirus. The large difference in prevalence rates between Amazonian natives and other groups and between older and younger natives suggest that Mayaro virus is endemic and enzootic in the rainforest, with sporadic outbreaks that determine differences in risk between birth cohorts of natives. Deep forest hunting may selectively expose native men, descendants of the Shuar and Huaronai ethnic groups, to the arthropod vectors of Mayaro virus in areas close to primate reservoirs.

Books and other documents suggested by health systems experts were also included. Review of the financing model enabled identifying the historical segmentation of Ecuador's health system; out of this, the Ministry of Public Health conceived its proposal to reform the financing model. The Ministry's proposed solutions are pooling of funds and payment of services at the first level of care through payment per capita adjusted for socioeconomic and demographic risks. Progress made in reforming the financing model includes design of the proposals and their implementation mechanisms, and discussions with stakeholders. Implementation of these changes may produce improvements for the health system in efficiency, spreading of risks, incentives for meeting health objectives, as well as contribute to its sustainability and advance toward universal health coverage. Nevertheless, legal, political, and operational constraints are hampering their implementation.

Keys of educational change in Ecuador

2018-01-01

Full Text Available The article analyzes the educational system in Ecuador. The Ecuadorian education system arouses international interest, especially in Latin America. In this essay we will try to answer these questions: What might be the relevant keys from the public education in Ecuador? Why has it reached its present level of development, particularly in inclusive education? What fundaments and policies are behind the results of the goals from Education for All (EFA 2000-2015 From the Dakar framework for Action? (World Education Forum, 2000. In light of these issues, the goal is to understand key factors and reasons that have contributed to the development of the Ecuadorian public education. In terms of methodology, the approach is qualitative, dialectical, documentary and descriptive (Mc Millan and Schumacher, 2005. The research is proposed as a case study, where the choice of the case is justified by its novelty, its degree of development and its emphasis on inclusion and equity in all educational levels. With this aim, it is made a descriptive analysis of the rules underlying the changes in the educational system in Ecuador in the last three decades and it is carried out, particularly since 2008, following the last Constitution (Constituent Assembly, 2008. Tables as an analytical contribution of the authors are offered. Also data endorsed by authors and agencies of maximum national and international prestige are detailed and they realize the effectiveness of policies and such changes.

Neoliberalism and shrimp industry in Ecuador

Full Text Available Analysis of the effects of the shrimp industry development in the mangrove ecosystem, the socio-environmental conflicts generated and its relationship with neoliberalism and the financial crisis of 1999 in Ecuador. After a review of the importance of the mangrove ecosystem, the stages of the shrimp expansion, its promoters, the mangrove deforestation and the socio-environmental effects caused, I will analyze the shrimp crisis, its parallels with the financial crisis of 1999 and its subsequent recovery. I will show that the shrimp industry expanded in mangrove areas in order to reduce costs, even breaking the law and creating environmental degradation, vulnerability of the costs and loss of natural resources, based on the exploitation and privatization of a public good. This created unemployment, migration and impoverishment to local populations and costs that the State will have to assume. Therefore, it is a process of “accumulation by dispossession” characteristic of neoliberalism.

The Instituto de Energia Solar has been dealing with quality control issues for rural electrification for many years. In the framework of project DOSBE (Development of Electricity Service Operators for Poverty Alleviation in Ecuador and Peru), a technical toolkit has been developed to implement adapted integral quality control procedures for photovoltaic systems (covering all components and equipment, installation and servicing), applicable at a local and regional scale, with the overall aim of increasing the confidence in photovoltaic systems. This toolkit was applied in the evaluation of an existing microgrid in Ecuador, which is described in this paper. The toolkit and the detailed results of its application are presented in a published document which is being widely distributed among the stakeholders of rural electrification in Ecuador and Peru. It can be downloaded from the web page of the DOSBE project: www.dosbe.org (orig.)

Sensitivity analysis of effective population size to demographic parameters in house sparrow populations.

The ratio between the effective and the census population size, Ne/N, is an important measure of the long-term viability and sustainability of a population. Understanding which demographic processes that affect Ne/N most will improve our understanding of how genetic drift and the probability of fixation of alleles is affected by demography. This knowledge may also be of vital importance in management of endangered populations and species. Here, we use data from 13 natural populations of house sparrow (Passer domesticus) in Norway to calculate the demographic parameters that determine Ne/N. Using the global variance-based Sobol' method for the sensitivity analyses, we found that Ne/N was most sensitive to demographic variance, especially among older individuals. Furthermore, the individual reproductive values (that determine the demographic variance) were most sensitive to variation in fecundity. Our results draw attention to the applicability of sensitivity analyses in population management and conservation. For population management aiming to reduce the loss of genetic variation, a sensitivity analysis may indicate the demographic parameters towards which resources should be focused. The result of such an analysis may depend on the life history and mating system of the population or species under consideration, because the vital rates and sex-age classes that Ne/N is most sensitive to may change accordingly. © 2017 John Wiley & Sons Ltd.

Challenges for an Active Role of Women in Physics in Ecuador

Ayala, Paola; Guaño, Sonia; Apolo, Alberto Celi

2009-04-01

The social reality of Ecuador is not far from the experience of most countries of the Andean region in South America. Many factors contribute to a preference for short-learning-curve or business-oriented careers, and also make traditional and time-demanding careers less appealing. Physics is one of the least attractive professions in a country like Ecuador. However, in the last few years, the number of bachelor's-degree candidates in physics has increased significantly. This result, together with the new postgraduate courses offered inland, show promising changes for the future of this career. Developed countries face challenges that involve mainly gender issues in the scientific daily routine, whereas in Ecuador the challenge is still to attract students to this scientific path regardless of their gender.

In Ecuador, Helicobacter pylori infections are highly prevalent. A total of 42 H. pylori clinical isolates from 86 patients attending the outpatient clinic of the gastroenterology department of the university hospital of Guayaquil in Ecuador were characterized. Their susceptibility, and cagA and vacA status were determined. Resistance to metronidazole and clarithromycin was found in 80.9% and 9.5% of strains, respectively. Neither amoxicillin- nor tetracycline-resistant strains were found. The most prevalent genotype was the cagA(+), vacA s1b,m1 type. This genotype was associated with gastric cancer and peptic ulcer. Typing by random amplified polymorphic DNA showed no genetic relationship among the strains.

Is it possible for a country in the process of development to comply with the environmental Kuznets curve (EKC) hypothesis in the medium term? This is the question that inspired this study. This paper is an extension of a previous study focused on economic development and CO 2 emissions in the coming years in Ecuador (Robalino-López et al., submitted for publication). The main goal of this paper is to analyze whether the EKC hypothesis holds within the period 1980–2025 under four different scenarios. This paper uses co-integration techniques (Stock and Watson, 2010) to test the existence of the EKC hypothesis in Ecuador in the medium term using Jaunky's (2011) specification. Our proposal goes a step further than previous contributions, and intends to see under which conditions a country could approach the fulfilment of this hypothesis in the medium term. Results do not support the fulfilment of the EKC, nevertheless, our estimations show that Ecuador could be on the way to achieving environmental stabilization in the near future if economic growth is combined with an increase in the use of renewable energies, an improvement of the productive sectoral structure, and the use of a more efficient fossil fuel technology. - Author-Highlights: • We model the CO 2 emissions in Ecuador for the next decade under several scenarios. • We study the environmental Kuznets curve in the medium term in Ecuador. • We show that Ecuador will enter into stage 2 of the environmental Kuznets curve in the near future

Marín-Armijos, Diego; Quezada-Ríos, Noelia; Soto-Armijos, Carolina; Mengual, Ximo

2017-01-01

Abstract Syrphidae is one of the most speciose families of true flies, with more than 6,100 described species and worldwide distribution. They are important for humans acting as crucial pollinators, biological control agents, decomposers, and bioindicators. One third of its diversity is found in the Neotropical Region, but the taxonomic knowledge for this region is incomplete. Thus, taxonomic revisions and species checklists of Syrphidae in the Neotropics are the highest priority for biodiversity studies. Therefore, we present the first checklist of Syrphidae for Ecuador based on literature records, and provide as well the original reference for the first time species citations for the country. A total of 201 species were recorded for Ecuador, with more than 600 records from 24 provinces and 237 localities. Tungurahua, Pastaza, and Galápagos were the best sampled provinces. Although the reported Ecuadorian syrphid fauna only comprises 11.2 % of the described Neotropical species, Ecuador has the third highest flower fly diversity density after Costa Rica and Suriname. These data indicate the high species diversity for this country in such small geographic area. PMID:29200924

Full Text Available ABSTRACT First records of parasitoids attacking the Asian citrus psyllid in Ecuador. The objective of the current study was to investigate the presence of natural enemies of Diaphorina citri (Hemiptera: Liviidae (the Asian citrus psyllid in Ecuador. Incidence of parasitoid Diaphorencyrtus aligarhensis (Hymenoptera: Encyrtidae was assessed between November 2015 and March 2016, in Letamendi, Febres-Cordero and Tarqui, urban districts of Guayaquil. Highest incidence of parasitism occurred in those regions and seasons of the year with the highest temperatures commensurate with increase of citrus plant shoots. Similar to their host, these parasitoids appear to have established in Ecuador by accident, and were not the result of purposeful introduction. This fortuitous introduction is a potentially helpful tool in controlling the Asian citrus psyllid, and potentially Huanglongbing.

Between April 2001 and March 2004, the Directly Observed Therapy-Short course (DOTS) program was successfully implemented by the National Tuberculosis control program, with assistance from the Canadian Lung Association, in three provinces of Ecuador, where 52% of the population of the country reside. Markov modelling was used to project TB-related morbidity, mortality and costs if the former TB control program (status quo) had continued or if the newly expanded DOTS program is maintained over 20 years. Extensive sensitivity analyses were used to determine the effect on projected outcomes of varying key assumptions. If DOTS is maintained over the next 20 years, we predict that 18,760 cases and 15,812 TB-related deaths will be prevented, resulting in societal savings of dollars 203 million and government savings of dollars 7.1 million (all costs in dollars US). These findings were robust in extensive sensitivity analyses. Given the initial investment of dollars 3 million for DOTS implementation, this would mean a cost of dollars 190 per life saved. Implementation of DOTS could yield very substantial public health and economic benefits for Ecuador. These results demonstrate the benefits from Canadian government support for DOTS implementation in low- and middle-income countries.

Medicinal plants of the Achuar (Jivaro) of Amazonian Ecuador: ethnobotanical survey and comparison with other Amazonian pharmacopoeias.

Giovannini, Peter

2015-04-22

This paper presents the first ethnobotanical survey conducted among the Achuar (Jivaro), indigenous people living in Amazonian Ecuador and Peru. The aims of this study are: (a) to present and discuss Achuar medicinal plant knowledge in the context of the epidemiology of this population (b) to compare the use of Achuar medicinal plants with the uses reported among the Shuar Jivaro and other Amazonian peoples. The author conducted field research in 9 indigenous villages in the region of Morona Santiago and Pastaza in Ecuador. Semi-structured interviews on local illnesses and herbal remedies were carried out with 82 informants and plant specimens were collected and later identified in Quito. A literature research was conducted on the medicinal species reported by Achuar people during this study. The most reported medicinal plants are species used by the Achuar to treat diarrhoea, parasites infection, fractures, wounds, and snakebites. Informants reported the use of 134 medicinal species for a total of 733 recorded use-reports. Of these 134 species, 44 are reported at least 3 times for one or more specific disease condition for a total of 56 uses. These species are considered a core kit of medicinal plants of the Achuar of Ecuador. Most of these medicinal species are widely used in the Amazon rainforest and in many other parts of Latin America. The author documented a core kit of 44 medicinal plants used among the Achuar of Ecuador and found that this core set of medicinal plants reflects local epidemiological concerns and the pharmacopoeias of the Shuar and other Amazonian groups. These findings suggest that inter-group diffusion of medicinal plant knowledge had a prominent role in the acquisition of current Achuar knowledge of medicinal plants.

An oil spill of 11,700 barrels of heavy crude oil occurred at an OCP Ecuador S.A. pipeline in a high biodiversity area in eastern Ecuador on February 25, 2009. The pipeline breakage was due to stress caused by an earth movement. The aim of this paper is to present the methodology used by the company for the emergency response. First of all, medical assistance was provided to the inhabitants of the area as a safety precaution and water was distributed to them while other workers contained the spill and cleaned the area. Residents were then offered temporary jobs participating in the cleaning efforts. Throughout the cleanup process, the media and the population were kept informed of how the process was progressing in an open and transparent manner. This methodology ensured the success of the cleanup and restoration work in a timely manner and this methodology can now be used and further developed for handling future events.

The Joint United Nations Program on HIV/AIDS estimates that between 0.3% and 0.7% of adults aged 15 to 49 years were living with HIV in Ecuador in 2013. However, very little is known about the HIV prevalence rate among men who have sex with men (MSM) in that country. A cross-sectional survey was conducted to investigate the knowledge, attitudes, and practices regarding HIV/AIDS as well as to estimate the prevalence of HIV among MSM in one of the cities with high HIV prevalence rates in Ecuador. In this study, questionnaires were administered to 307 adult MSM. An HIV prevalence of 10% was observed. Knowledge about HIV was high; 91% of participants could identify how HIV is transmitted. Although consistent condom use for anal sex was relatively high (89%) among participants who reported having pay-for-service clients, only 64% reported using a condom during oral sex with a client. Participants who had multiple male sexual partners (i.e., their stable male partners plus other partner[s]) had 3.7 times higher odds of testing positive for HIV compared with those who did not. They also had reduced odds of condom use. Participants who were forced to have anal receptive sex had 3 times higher odds of testing positive for HIV. Despite the finding that participants exhibited high knowledge about HIV/AIDS, a high prevalence rate of HIV was observed, which warrants targeted behavioral interventions. These data are consistent with MSM being one of the highest at-risk population groups for HIV in this region of Ecuador.

Environmental nickel exposure from oil refinery emissions: a case study in Ecuador.

Harari, Raúl; Harari, Florencia; Forastiere, Francesco

2016-01-01

Nickel is a strong skin and respiratory sensitizer and a recognized carcinogen. Oil refineries are important sources of atmospheric emissions of toxic pollutants, including nickel. Populations residing close to oil refineries are at potential risk. The aim of this study was to evaluate the exposure to nickel in a population living close to the largest oil refinery in Ecuador, located in the city of Esmeraldas. We recruited 47 workers from the oil refinery as well as 195 students from 4 different schools close to the plant and 94 students from another school 25 km far from the industry. Urinary nickel concentrations were used to assess the exposure to nickel. Students from the school next to the oil refinery showed the highest urinary nickel concentrations while workers from the refinery showed the lowest concentrations. Median nickel concentrations were > 2µg/L in all study groups. The populations living close to the oil refineries are potentially exposed to nickel from atmospheric emissions. Further studies investigating nickel-related health effects in the population residing close to the refinery of Esmeralda are needed.

2009-02-01

To compare cancer mortality rates in Amazon cantons (counties) with and without long-term oil exploration and extraction activities. Mortality (1990 through 2005) and population census (1990 and 2001) data for cantons in the provinces of the northern Amazon Region (Napo, Orellana, Sucumbios, and Pastaza), as well as the province with the capital city of Quito (Pichincha province) were obtained from the National Statistical Office of Ecuador, Instituto Nacional del Estadistica y Censos (INEC). Age- and sex-adjusted mortality rate ratios (RR) and 95% confidence intervals (CI) were estimated to evaluate total and cause-specific mortality in the study regions. Among Amazon cantons with long-term oil extraction, activities there was no evidence of increased rates of death from all causes (RR = 0.98; 95% CI = 0.95-1.01) or from overall cancer (RR = 0.82; 95% CI = 0.73-0.92), and relative risk estimates were also lower for most individual site-specific cancer deaths. Mortality rates in the Amazon provinces overall were significantly lower than those observed in Pichincha for all causes (RR = 0.82; 95% CI = 0.81-0.83), overall cancer (RR = 0.46; 95% CI = 0.43-0.49), and for all site-specific cancers. In regions with incomplete cancer registration, mortality data are one of the few sources of information for epidemiologic assessments. However, epidemiologic assessments in this region of Ecuador are limited by underreporting, exposure and disease misclassification, and study design limitations. Recognizing these limitations, our analyses of national mortality data of the Amazon Region in Ecuador does not provide evidence for an excess cancer risk in regions of the Amazon with long-term oil production. These findings were not consistent or supportive of earlier studies in this region that suggested increased cancer risks.

To generate normative data for the Stroop Word-Color Interference test in Spanish-speaking pediatric populations. The sample consisted of 4,373 healthy children from nine countries in Latin America (Chile, Cuba, Ecuador, Guatemala, Honduras, Mexico, Paraguay, Peru, and Puerto Rico) and Spain. Each participant was administered the Stroop Word-Color Interference test as part of a larger neuropsychological battery. The Stroop Word, Stroop Color, Stroop Word-Color, and Stroop Interference scores were normed using multiple linear regressions and standard deviations of residual values. Age, age2, sex, and mean level of parental education (MLPE) were included as predictors in the analyses. The final multiple linear regression models showed main effects for age on all scores, except on Stroop Interference for Guatemala, such that scores increased linearly as a function of age. Age2 affected Stroop Word scores for all countries, Stroop Color scores for Ecuador, Mexico, Peru, and Spain; Stroop Word-Color scores for Ecuador, Mexico, and Paraguay; and Stroop Interference scores for Cuba, Guatemala, and Spain. MLPE affected Stroop Word scores for Chile, Mexico, and Puerto Rico; Stroop Color scores for Mexico, Puerto Rico, and Spain; Stroop Word-Color scores for Ecuador, Guatemala, Mexico, Puerto Rico and Spain; and Stroop-Interference scores for Ecuador, Mexico, and Spain. Sex affected Stroop Word scores for Spain, Stroop Color scores for Mexico, and Stroop Interference for Honduras. This is the largest Spanish-speaking pediatric normative study in the world, and it will allow neuropsychologists from these countries to have a more accurate approach to interpret the Stroop Word-Color Interference test in pediatric populations.

Suicide affects people from different backgrounds, ethnical groups, socio-economic status and geographical locations. In Latin America, suicide reports arescarce, specially in Andean countries. In Ecuador, very few reports have partially described this phenomenon, nonetheless, estimation of the burden of disease (BoD) hasnever been reported in the country. A country-wide comparison was performed using the Ministry of Public Health's national databases of overall mortality, Hospital Discharges Database, and the Population Census of the National Institute of Census and Statistics (INEC). The study variables analyzed were age, geographical distribution to provincial level, sex, means of suicide, educational attainment, marital status and mortality. Linear Regression and relative Risk analysis were used to predict outcome and the likelihood that suicide occur among study variables. In the last 15 years, 13,024 suicides were officially reported. Men were 3 times more likely than women to die by suicide. The overall age-adjusted suicide ratio in Ecuador corresponds to 7.1 per 100,000 per year. The sex-specific rates were 5.3 in women and 13.2 in men. The primary mean of suicide was hanging X70 (51.1%), followed by self-poisoning X68-X69 (35.2%) and firearms X72-X74 (7.6%). Provinces located at higher altitude reported higher rates than those located at sea level (9 per 100,000 vs 4.5 per 100.000). The total economic loss due to suicide was estimated to be $852.6 million during the 15 years' analysis. This is the first geodemographic study exploring the complete burden of suicide in Ecuador and one of the very few in Latin-America. In the last 15 years of available data, Ecuador ranks above the regional average with an adjusted suicide rate of 7.1 per 100,000 inhabitants. An important finding is that Suicide affects rather younger populations, adding more than 10,000 years of premature years of life lost (YYL) between 2001 and 2015, becoming the first and fourth

el uso consistente del condón en esta población.OBJECTIVE: Whilst existing data suggests that the HIV epidemic in Ecuador is concentrated amongst men who have sex with men (MSM, there is very little available information on the situation of key populations, i.e. those most at risk of HIV infection and/or transmitting the infection. In particular, there is very little known about sex workers (SWs, their rate of condom use and other behaviors and characteristics with respect to the risk of acquiring sexually transmitted infections (STIs. This study presents findings from a survey carried out with SWs in eight cities in Ecuador. MATERIAL AND METHODS: Using a cross-sectional design, a questionnaire focusing on behaviours, attitudes and socio-economic and demographic characteristics was administered to SWs in eight cities in Ecuador. These eight cities together account for the majority of the population in the country, and they were also identified as the locations with high reported levels of HIV. RESULTS: Information from a total of 2867 SWs was obtained, the majority were captured in their workplaces. Most of SWs interviewed carry out their activities in closed settings dedicated to sex work (i.e. not in the street. The average age of respondents was 28 (95%CI 27-29, and around half of them live with a male partner (married or not. The rate of condom use with the last client was 88% (82% consistently with the last three, whilst with regular partners it was 6%. A high index of life-skills, high socio-economic status and having an official document that allows them to work, were positively associated with condom use with clients (PR [CI 95%] 1.40 [1.40-1.40], 1.37 [1.36-1.37], y 7.26 [6.87-7.46], respectively. CONCLUSIONS: Whilst condom use with clients amongst Ecuadorian SWs is high, this diminishes if one analyzes consistent condom use and is notably low with respect to regular partners. Condom use appears to be related to variables that can be linked to

To differentiate the effects of food vouchers and training in health and nutrition on consumption and dietary diversity in Ecuador by using an experimental design. Interventions involved enrolling three groups of approximately 200 randomly selected households per group in three provinces in Ecuador. Power estimates and sample size were computed using the Optimal Design software, with a power of 80 %, at 5 % of significance and with a minimum detectable effect of 0·25 (sd). The first group was assigned to receive a monthly food voucher of $US 40. The second group was assigned to receive the same $US 40 voucher, plus training on health and nutrition issues. The third group served as the control. Weekly household values of food consumption were converted into energy intake per person per day. A simple proxy indicator was constructed for dietary diversity, based on the Food Consumption Score. Finally, an econometric model with three specifications was used for analysing the differential effect of the interventions. Three provinces in Ecuador, two from the Sierra region (Carchi and Chimborazo) and one from the Coastal region (Santa Elena). Members of 773 households randomly selected (n 4343). No significant impact on consumption for any of the interventions was found. However, there was evidence that voucher systems had a positive impact on dietary diversity. No differentiated effects were found for the training intervention. The most cost-effective intervention to improve dietary diversity in Ecuador is the use of vouchers to support family choice in food options.

Ecuador's current nutrition policies have not taken adequate notice of the double burden of malnutrition and continue to focus on stunting and to a lesser extent on overweight, without addressing the simultaneous presence of undernutrition, micronutrient deficiencies, and overweight or obesity (OW/OB). The aim of this article was to describe the prevalence and distribution of undernutrition (stunting, anemia, and zinc deficiency), overweight, and obesity in Ecuador to explore the evolving double burden of malnutrition at the national, household, and individual levels and to discuss whether current public health policies are addressing the double burden. Data from the 2012 Ecuadorian National Health and Nutrition Survey (ENSANUT-ECU) was used to estimate the dual burden of malnutrition at the national, household, and individual levels in children Ecuador. Although integrated approaches to address the emerging double burden are required, public health policies to date have not responded adequately. © 2014 American Society for Nutrition.

Ecuador's energy policy mix: Development versus conservation and nationalism with Chinese loans

International Nuclear Information System (INIS)

Escribano, Gonzalo

2013-01-01

Ecuador's energy policy faces a complex variety of political and economic objectives that are difficult to reconcile in a consistent manner. Ecuador is a small oil producer and exporter with significant renewable (mainly hydropower) resources, hosting some of the richest biodiversity areas in the world, part of which are inhabited by so far indigenous un-contacted people. Being a developing country, tensions arise between conservation aims and development imperatives, as well as between resource nationalism and much-needed foreign financing. However, the really limiting factor for the country's energy development seems to be its constraints in financing the government's development and redistributive policies. Resorting to Chinese loans-for-oil may be part of the solution in the short term, but it does not substitute for a more consistent energy policy. Ecuador's case illustrates the dilemmas of energy policy in natural resource-rich developing countries when confronted with diverging political economy, social, environmental and macro-financial goals. - Highlights: ► Ecuador's energy policy lacks coherence and is plagued with inconsistencies. ► Its three main drivers are development, conservation and resource nationalism. ► Fulfilling President Correa's social agenda requires increasing oil production. ► Conservation demands have been subjected to developmental imperatives. ► Chinese loans and investments limit resource nationalism and favour pragmatism

This study set out to describe the association between the maternal mortality ratio (MMR) estimates and a set of socioeconomic indicators and compute the MMR inequalities among the provinces of Ecuador. A cross-sectional ecological study was conducted, using data for 2014 from the country's 24 provinces. The MMR estimate was calculated for each province, as well as the association and its strength between MMR and specific socioeconomic indicators. For the indicators that were found to be significantly associated with MMR, inequality measurements were computed. Despite a relatively low MMR for Ecuador overall, ratios differed substantially among the provinces. Five socioeconomic indicators proved to be statistically significantly associated with MMR: total fertility rate, the percentage of indigenous population, the percentage of households with children who do not attend school, gross domestic product, and the percentage of houses with electrical service. Of these five, only three had MMR inequalities that were significant: total fertility rate, gross domestic product, and the percentage of households with electricity. This study supports research arguing that national averages can be misleading, as they often hide differences among subgroups at the local level. The findings also suggest that MMR is significantly associated with some socioeconomic indicators, including ones linked with significant health outcome inequalities. In order to reduce health inequities, it is crucial that countries look beyond national averages and identify the subgroups being left behind, explore the particular social determinants that generate these health inequalities, and examine the specific barriers and other factors affecting the subgroups most vulnerable to maternal health inequalities.

Simulating progressive social transfers. Gas subsidies and solidarity bonds in Ecuador

Cuesta, J.; Ponce, J.; Leon, M.

2004-02-01

After two decades of neglect, social expending has become a cornerstone in the current fight against poverty in Ecuador. Ecuador is presently considering the elimination of regressive gas subsidies and the shift of these resources into pro-poor targeted Solidarity Bonds. Great distributive gains are expected from this reform. There are, however, a number of considerations that may prevent this policy shift from obtaining substantial poverty and equality gains. Despite their regressivity, implicit gas subsidies still represent a considerable proportion of total household consumption among poor households. Also, solidarity bonds siphon off a substantial share of their total benefits to middle income groups. This paper estimates the redistributive consequences of policy reforms on gas subsidies and solidarity bonds in Ecuador. A simulation methodology estimates both direct and indirect (labour-driven) distributive effects of four alternative scenarios: (1) total elimination of gas subsidies; (2) selective elimination of gas subsidies among non-poor households; (3) total elimination of gas subsidies and shift of resources to solidarity bonds targeted to the poor; (4) selective elimination of gas subsidies and shift of resources to solidarity bonds targeted to the poor. Estimates confirm that the redistributive gains from these reforms are rather small both for poverty and inequality. Incentives to work following the elimination of subsidies compensate, or even outdo, immediate poverty rises. Also, the elimination of gas subsidies without further expansion of subsidy bonds will unambiguously increase poverty in Ecuador between one and one and a half percent points

Full Text Available RESUMEN: El presente trabajo analiza el impacto que en la actualidad tiene la cooperación internacional para el desarrollo en la definición de agendas locales de seguridad ciudadana en Ecuador. En Ecuador se observa una heterogeneidad de proyectos que de alguna manera buscan apoyar y fortalecer iniciativas de prevención de la violencia social. No obstante, en una escala nacional siguen predominando los esfuerzos antinarcóticos apoyados por las donaciones de países como los Estados Unidos. Se cuestiona entonces la injerencia que tiene la cooperación en el desbalance que se genera entre los esfuerzos locales y nacionales y que dificulta la consolidación de agendas locales de seguridad ciudadana más ajustadas a las necesidades y demandas de los y las ciudadanos/as.ABSTRACT: This article analyzes the current impact foreign aid has on the definition of local «citizen security» agendas in Ecuador. Regarding citizen security, Ecuador has heterogeneous projects that seek to strengthen and support social violence prevention initiatives. However, at the national level antidrug efforts prevail, receiving the support of important donors such as the Unites States. The article thus questions the role played by foreign aid in the imbalances found between local and national efforts, that in turn create great difficulty in the definition of a local citizen security agenda more in tuned with citizen’s needs and demands.

Chagas disease is a neglected tropical disease caused by the protozoan parasite Trypanosoma cruzi. In Ecuador, Triatoma dimidiata and Rhodnius ecuadoriensis are the main vector species, responsible for over half of the cases of T. cruzi infection in the country. T. dimidiata is believed to have been introduced in Ecuador during colonial times, and its elimination from the country is thus believed to be feasible. We investigated here the molecular ecology of T. dimidiata and T. cruzi in costal Ecuador to further guide control efforts. Analysis of the Internal Transcribed Spacer 2 (ITS-2) of 23 specimens from Progreso, Guayas, unambiguously supported the likely importation of T. dimidiata from Central America to Ecuador. The observation of a very high parasite infection rate (54%) and frequent feeding on humans (3/5) confirmed a continued risk of transmission to humans. All genotyped parasites corresponded to TcI DTU and Trypanosoma rangeli was not detected in T. dimidiata. TcI subgroups corresponded to TcIa (25%), and mixed infections with TcIa and TcId (75%). Further studies should help clarify T. cruzi genetic structure in the country, and the possible impact of the introduction of T. dimidiata on the circulating parasite strains. The elevated risk posed by this species warrants continuing efforts for its control, but its apparent mobility between peridomestic and domestic habitats may favor reinfestation following insecticide spraying.

Maritza Barrera

2017-01-01

Full Text Available In 2010, new Chinese strains of porcine epidemic diarrhea virus (PEDV, clinically more severe than the classical strains, emerged. These strains were spread to United States in 2013 through an intercontinental transmission from China with further spreading across the world, evidencing the emergent nature of these strains. In the present study, an analysis of PEDV field sequences from Ecuador was conducted by comparing all the PEDV S gene sequences available in the GenBank database. Phylogenetic comparisons and Bayesian phylogeographic inference based on complete S gene sequences were also conducted to track the origin and putative route of PEDV. The sequence from the PED-outbreak in Ecuador was grouped into the clade II of PEDV genogroup 2a together with other sequences of isolates from Mexico, Canada, and United States. The phylogeographic study revealed the emergence of the Chinese PEDV strains, followed by spreading to US in 2013, from US to Korea, and later the introduction of PEDV to Canada, Mexico, and Ecuador directly from the US. The sources of imports of live swine in Ecuador in 2014 were mainly from Chile and US. Thus, this movement of pigs is suggested as the main way for introducing PEDV to Ecuador.

Adolescent-Friendly Health Services (AFHSs) are those that are accessible, acceptable, equitable, appropriate and effective for different youth sub-populations. This study investigated the process through which four clinics in two countries - Peru and Ecuador - introduced, developed and sustained AFHSs. A multiple case study design was chosen, and data from each clinic were collected through document review, observations and informant interviews. National level data were also collected. Data were analysed following thematic analysis. The findings showed that the process of introducing, developing and sustaining AFHSs was long term, and required a creative team effort and collaboration between donors, public institutions and health providers. The motivation and external support was crucial to initiating and sustaining the implementation of AFHSs. Health facilities' transformation into AFHSs was linked to the broader organisation of country health systems, and the evolution of national adolescent health policies. In Peru, the centralised approach to AFHSs introduction facilitated the dissemination of a comprehensive national model to health facilities, but dependency on national directives made it more difficult to systemise them when ideological and organisational changes occurred. In Ecuador, a less centralised approach to introducing AFHSs made for easier integration of the AFHSs model.

Full Text Available The lack of information about the media landscape in Ecuador has prompted the Department of Communication Sciences at the Private Technical University of Loja to map the country's media, production companies, and advertising and public relations agencies. The need for a database on communication issues is still latent in Ecuador. Some public and private agencies have made some contributions to the construction of physical or virtual repositories, but the data provided have been limited to basic, often outdated, contact information. Based on a sample of over one thousand media companies, this study describes their structure, legal and corporate organisation, geographical location, contents, reach, and provided services. This study is an approximation to the country’s media reality and is part of a wider research project entitled “Mapa de la Comunicación de Ecuador” (“Ecuador’s Media Map”.

The frequency of mutations in pfCRT and DHFR/DHPS genes of Plasmodium falciparum associated with resistance to chloroquine and sulfadoxine-pyrimethamine was evaluated in 83 strains from the districts of Esmeralda and Machala, located on the borders of Ecuador-Peru and Ecuador-Colombia in 2002. Polymerase chain reaction (PCR), conventional and its variants, was used. Mutations in the pfCRT gene were found in more than 90% of the samples from Esmeralda and Machala. For the DHFR gene, 90% of the strains were mutant samples from Esmeralda, 3 were double mutations and 1 was a triple mutation. In Machala, 25% were simple mutant forms and 75% mixed mutant forms (wild forms/mutant). In conclusion, resistance to chloroquine has been fixed in strains carrying K76T pfCRT mutation, whereas genetic imprinting for resistance to pyrimethamine is evolving, particularly in the district of Esmeralda.

Estimating demographic parameters from large-scale population genomic data using Approximate Bayesian Computation

2012-03-01

Full Text Available Abstract Background The Approximate Bayesian Computation (ABC approach has been used to infer demographic parameters for numerous species, including humans. However, most applications of ABC still use limited amounts of data, from a small number of loci, compared to the large amount of genome-wide population-genetic data which have become available in the last few years. Results We evaluated the performance of the ABC approach for three 'population divergence' models - similar to the 'isolation with migration' model - when the data consists of several hundred thousand SNPs typed for multiple individuals by simulating data from known demographic models. The ABC approach was used to infer demographic parameters of interest and we compared the inferred values to the true parameter values that was used to generate hypothetical "observed" data. For all three case models, the ABC approach inferred most demographic parameters quite well with narrow credible intervals, for example, population divergence times and past population sizes, but some parameters were more difficult to infer, such as population sizes at present and migration rates. We compared the ability of different summary statistics to infer demographic parameters, including haplotype and LD based statistics, and found that the accuracy of the parameter estimates can be improved by combining summary statistics that capture different parts of information in the data. Furthermore, our results suggest that poor choices of prior distributions can in some circumstances be detected using ABC. Finally, increasing the amount of data beyond some hundred loci will substantially improve the accuracy of many parameter estimates using ABC. Conclusions We conclude that the ABC approach can accommodate realistic genome-wide population genetic data, which may be difficult to analyze with full likelihood approaches, and that the ABC can provide accurate and precise inference of demographic parameters from

Full Text Available Tropical countries are thought to play an important role in the global behavior of respiratory infections such as influenza. The tropical country of Ecuador has almost no documentation of the causes of acute respiratory infections. The objectives of this study were to identify the viral agents associated with influenza like illness (ILI in Ecuador, describe what strains of influenza were circulating in the region along with their epidemiologic characteristics, and perform molecular characterization of those strains.This is a prospective surveillance study of the causes of ILI based on viral culture of oropharyngeal specimens and case report forms obtained in hospitals from two cities of Ecuador over 4 years. Out of 1,702 cases of ILI, nine viral agents were detected in 597 patients. During the time of the study, seven genetic variants of influenza circulated in Ecuador, causing six periods of increased activity. There appeared to be more heterogeneity in the cause of ILI in the tropical city of Guayaquil when compared with the Andean city of Quito.This was the most extensive documentation of the viral causes of ILI in Ecuador to date. Influenza was a common cause of ILI in Ecuador, causing more than one outbreak per year. There was no well defined influenza season although there were periods of time when no influenza was detected alternating with epidemics of different variant strains.

Endemic goiter is a health problem in many areas of the world; in some areas the disease is so severe that cretinism and other defects are found. In many areas geographic, economic, and other factors prevent the use of iodized salt as a preventive measure. Field studies were begun in 1966 to determine the feasibility and effectiveness of parenteral administration of iodized oil in goiter prevention. Studies were carried out in Ecuador and Peru. In Ecuador 2 villages were chosen in which the prevalence of goiter was about 60%; in Peru 3 villages were chosen where incidence was about 50%. Prevalence of goiter decreased for 20 months during the study but then began to rise again with the maximum reduction seen up to age 18 and minimal reduction after 40 years of age. The control groups in the study experienced only slight decreases in rate of incidence. Cretinism has not yet appeared among the progeny of the population injected with iodized oil but several instances have appeared in control groups. The use of iodized oil as a public health procedure for the prevention of endemic goiter and its associated defects is an acceptable measure in regions where salt iodization cannot be done.

We mapped leukemia risk among children and youths in the Azuay province, Rio Paute river basin, Ecuador, in 2000-2010, using a Bayesian disease mapping model. We assessed the comprehensiveness of the list of leukemia cases from the Sociedad de Lucha contra el Càncer en el Ecuador (SOLCA) Hospital in Cuenca, the only referral center for oncology in the whole Rio Paute area, by comparison to the Quito cancer registry. Risk of leukemia did not vary significantly by canton within the Azuay province. However, a moderate increase in risk of borderline statistical significance was observed in the city of Cuenca and particularly among males in a heavily industrialized parish, who had an almost eight-fold excess (95% CI 3.03, 20.39, p = 0.01) of AML. Analytical studies are warranted to properly address specific etiological factor of leukemia among children and youths of the Azuay province of Ecuador.

To explore socioeconomic and lifestyle factors associated with the prevalence of self-reported chronic conditions among older adults in Ecuador. The sample was drawn from the nationally representative observational cross-sectional data of the Health, Well-Being, and Aging survey conducted in Ecuador in 2009. Logistic regression models were used to explore the association between socioeconomic and lifestyle factors and the prevalence of selected chronic conditions. Older women in Ecuador are more likely than men to have been previously diagnosed with diabetes, heart disease, high blood pressure, and arthritis. Results suggest no difference by education or health insurance on number and type of self-reported chronic conditions. However, older adults who resided in the coastal area were more likely to report having diabetes, heart disease, high blood pressure, and stroke than those in the highlands. Living in rural areas was associated with lower odds of having diabetes and high blood pressure. Compared to white older adults, indigenous older adults were less likely to report having high blood pressure, but more likely to report having arthritis. Older age in Ecuador is marked by low educational levels and poverty. Female gender and living in coastal areas were associated with higher risks of self-reported chronic conditions.

Fully populated VCM or the hidden parameter

Full Text Available Least-squares estimates are trustworthy with minimal variance if the correct stochastic model is used. Due to computational burden, diagonal models that neglect correlations are preferred to describe the elevation dependency of the variance of GPS observations. In this contribution, an improved stochastic model based on a parametric function to take correlations between GPS phase observations into account is presented. Built on an adapted and flexible Mátern function accounting for spatiotemporal variabilities, its parameters can be fixed thanks to Maximum Likelihood Estimation or chosen apriori to model turbulent tropospheric refractivity fluctuations. In this contribution, we will show in which cases and under which conditions corresponding fully populated variance covariance matrices (VCM replace the estimation of a tropospheric parameter. For this equivalence “augmented functional versus augmented stochastic model” to hold, the VCM should be made sufficiently largewhich corresponds to computing small batches of observations. A case study with observations from a medium baseline of 80 km divided into batches of 600 s shows improvement of up to 100 mm for the 3Drms when fully populated VCM are used compared with an elevation dependent diagonal model. It confirms the strong potential of such matrices to improve the least-squares solution, particularly when ambiguities are let float.

Tapeworms Taenia solium and Taenia saginata are the causative agents of taeniasis/cysticercosis. These are diseases with high medical and veterinary importance due to their impact on public health and rural economy in tropical countries. The re-emergence of T. solium as a result of human migration, the economic burden affecting livestock industry, and the large variability of symptoms in several human cysticercosis, encourage studies on genetic diversity, and the identification of these parasites with molecular phylogenetic tools. Samples collected from the Ecuadorian provinces: Loja, Guayas, Manabí, Tungurahua (South), and Imbabura, Pichincha (North) from 2000 to 2012 were performed under Maximum Parsimony analyses and haplotype networks using partial sequences of mitochondrial DNA, cytochrome oxidase subunit I (COI) and NADH subunit I (NDI), from Genbank and own sequences of Taenia solium and Taenia saginata from Ecuador. Both species have shown reciprocal monophyly, which confirms its molecular taxonomic identity. The COI and NDI genes results suggest phylogenetic structure for both parasite species from south and north of Ecuador. In T. solium, both genes gene revealed greater geographic structure, whereas in T. saginata, the variability for both genes was low. In conclusion, COI haplotype networks of T. solium suggest two geographical events in the introduction of this species in Ecuador (African and Asian lineages) and occurring sympatric, probably through the most common routes of maritime trade between the XV-XIX centuries. Moreover, the evidence of two NDI geographical lineages in T. solium from the north (province of Imbabura) and the south (province of Loja) of Ecuador derivate from a common Indian ancestor open new approaches for studies on genetic populations and eco-epidemiology.

Full Text Available This article identifies the main variables that explain judicial corruption in Chile, Peru, and Ecuador. Improving the current methodological strategies used to measure judicial corruption and incorporating endogenous and exogenous variables in the model, this article argues that legal training of the judges, respect for the judicial career, and the fragmentation of political power explain different degrees of judicial corruption. Through a comparative diachronic and synchronic research design of Chile, Peru and Ecuador, the article shows institutional designs with more legal steps will be more inclined to illegal payments or other types of judicial corruption.

Abstract Adults and nymphs of the Asian citrus psyllid, Diaphorina citri Kuwayama (Hemiptera: Psyllidae), were collected in the Guayaquil, Samborondón, and Durán cantons in coastal Ecuador. Psyllids were found in high numbers in citrus ( Citrus spp., Sapindales: Rutaceae) and orange jasmine ( Murraya exotica [L.] Jack, Sapindales: Rutaceae) trees within the Guayaquil-Samborondon-Duran conurbation; however, none was found during scoutings in the main citrus producing areas in coastal Ecuador. To the best of our knowledge, this is the first report of D. citri in Ecuador and the Pacific coastal plain of South America. PMID:25527601

The sufficient sample size that is needed to closely estimate the statistics for particular parameters are use to be an issue. Although sample size might had been calculated referring to objective of the study, however, it is difficult to confirm whether the statistics are closed with the parameter for a particular population. All these while, guideline that uses a p-value less than 0.05 is widely used as inferential evidence. Therefore, this study had audited results that were analyzed from various sub sample and statistical analyses and had compared the results with the parameters in three different populations. Eight types of statistical analysis and eight sub samples for each statistical analysis were analyzed. Results found that the statistics were consistent and were closed to the parameters when the sample study covered at least 15% to 35% of population. Larger sample size is needed to estimate parameter that involve with categorical variables compared with numerical variables. Sample sizes with 300 to 500 are sufficient to estimate the parameters for medium size of population.

2001-12-01

Full Text Available Objective. To explore the knowledge, beliefs, and practices (KBPs regarding cutaneous leishmaniasis (CL treatment held by an endemic population in Ecuador. Methods. A follow-up to research done several years before, this study used random cluster sampling to select 529 adults who lived in rural northwestern Ecuador. Data were collected over a 24-month period using in-depth interviews supplemented with qualitative methods. Results. Most of the subjects were familiar with CL. The interviewed persons described a large, diverse ethnomedical treatment inventory. Contrary to expectations, few treatment KBPs were predicted by gender, age, or prior CL experience. Factors reported as important in treatment decisions included female reproductive status, CL "type" (perceived form of the illness, lesion location, number of other infected household members, cost of the various treatments, treatment availability, and perceived treatment effectiveness. Subjects' strong motivation for prompt treatment appeared to be associated with beliefs regarding the inability of CL lesions to heal spontaneously, the disease's propensity to progress into fatal illnesses, and disfigurement. Despite increased familiarity with Glucantime® (meglumine antimonate, the conventional pentavalent antimonial drug used to treat CL in Ecuador, the proportion of subjects who had used it in their treatment remained low (20% while the prevalence of premature drug discontinuance appeared to have doubled in comparison to our earlier study. Conclusions. By itself, increased access to Glucantime® is unlikely to increase usage of the drug and to reduce its frequent premature discontinuance unless public health planners accommodate the health and illness world views of local populations. Efficacy and safety studies should be undertaken to investigate promising traditional remedies as possible alternatives to Glucantime®.Objetivo. Investigar los conocimientos, creencias y pr

Prenatal care is a pillar of public health, enabling access to interventions including prevention of mother-to-child transmission of HIV and congenital syphilis. This paper describes social factors related to use of prenatal care in Ecuador. In 2011 and 2012, participant clinical history and interview information was analyzed from a national probability sample of 5 998 women presenting for delivery or miscarriage services in 15 healthcare facilities in Ecuador, to estimate prevalence of HIV, syphilis, and Chagas disease, and prenatal care coverage. The study found that 94.1% of women had attended at least one prenatal visit, but that attendance at no less than four visits was 73.1%. Furthermore, lower educational level, greater number of pregnancies, occupation in the agriculture or livestock sector, and membership in ethnic indigenous, Afro-Ecuadorian, or other minority groups were factors associated with lack of use (no prenatal visits) or insufficient use of prenatal care (fewer than four visits or first visit at >20 weeks gestation) in Ecuador. These results point to persistence of marked inequalities in access to and use of prenatal health services attributable to socioeconomic factors and to the need to strengthen strategies to address them, to reach the goal of universal prenatal care coverage.

Globalization and local response to epidemiological overlap in 21st century Ecuador

Waters William F

2006-05-01

Full Text Available Abstract Background Third World countries are confronted by a complex overlay of two sets of health problems. Traditional maladies, including communicable diseases, malnutrition, and environmental health hazards coexist with emerging health challenges, including cardiovascular disease, cancer, and increasing levels of obesity. Using Ecuador as an example, this paper proposes a conceptual framework for linking epidemiologic overlap to emerging social structures and processes at the national and global levels. Discussion Epidemiologic trends can be seen as part of broader processes related to globalization, but this does not imply that globalization is a monolithic force that inevitably and uniformly affects nations, communities, and households in the same manner. Rather, characteristics and forms of social organization at the subnational level can shape the way that globalization takes place. Thus, globalization has affected Ecuador in specific ways and is, at the same time, intimately related to the form in which the epidemiologic transition has transpired in that country. Summary Ecuador is among neither the poorest nor the wealthiest countries and its situation may illuminate trends in other parts of the world. As in other countries, insertion into the global economy has not taken place in a vacuum; rather, Ecuador has experienced unprecedented social and demographic change in the past several decades, producing profound transformation in its social structure. Examples of local represent alternatives to centralized health systems that do not effectively address the complex overlay of traditional and emerging health problems.

José Estrada

2016-06-01

Full Text Available Telephony is a global service and thus telephone networks have been a coveted target for criminals. Now that voice can be transported over IP and that multiple services are integrated in a convergent model through Internet, there are more incentives to attack and more attackers. Moreover, the development of open source telephone applications has encouraged the massive use of IP telephony, but not an increased awareness about embedded security risks. Due to the current and intensive adoption of IP telephony systems in Ecuador, we conducted an exploration based on public information to obtain statistics about telephone systems connected to Internet in Ecuador. Additionally, using a deliberately vulnerable IP telephony system, we collected more data to do a preliminary analysis of threats to such systems. We found that hundreds of telephone systems were publicly available on the Internet and using outdated versions of Asterisk-based applications. We also found thousands of malicious interactions on the IP telephony system we deployed on the Internet.

The complex influence of ENSO on droughts in Ecuador

KAUST Repository

Vicente-Serrano, S. M.

2016-03-26

In this study, we analyzed the influence of El Niño–Southern Oscillation (ENSO) on the spatio-temporal variability of droughts in Ecuador for a 48-year period (1965–2012). Droughts were quantified from 22 high-quality and homogenized time series of precipitation and air temperature by means of the Standardized Precipitation Evapotranspiration Index. In addition, the propagation of two different ENSO indices (El Niño 3.4 and El Niño 1 + 2 indices) and other atmospheric circulation processes (e.g., vertical velocity) on different time-scales of drought severity were investigated. The results showed a very complex influence of ENSO on drought behavior across Ecuador, with two regional patterns in the evolution of droughts: (1) the Andean chain with no changes in drought severity, and (2) the Western plains with less severe and frequent droughts. We also detected that drought variability in the Andes mountains is explained by the El Niño 3.4 index [sea surface temperature (SST) anomalies in the central Pacific], whereas the Western plains are much more driven by El Niño 1 + 2 index (SST anomalies in the eastern Pacific). Moreover, it was also observed that El Niño and La Niña phases enhance droughts in the Andes and Western plains regions, respectively. The results of this work could be crucial for predicting and monitoring drought variability and intensity in Ecuador. © 2016 Springer-Verlag Berlin Heidelberg

Ecuador's economic history has been closely linked to Theobroma cacao L cultivation, and specifically to the native fine flavour Nacional cocoa variety. The original Nacional cocoa trees are presently in danger of extinction due to foreign germplasm introductions. In a previous work, a few non-introgressed Nacional types were identified as potential founders of the modern Ecuadorian cocoa population, but so far their origin could not be formally identified. In order to determine the putative centre of origin of Nacional and trace its domestication history, we used 80 simple sequence repeat (SSR) markers to analyse the relationships between these potential Nacional founders and 169 wild and cultivated cocoa accessions from South and Central America. The highest genetic similarity was observed between the Nacional pool and some wild genotypes from the southern Amazonian region of Ecuador, sampled along the Yacuambi, Nangaritza and Zamora rivers in Zamora Chinchipe province. This result was confirmed by a parentage analysis. Based on our results and on data about pre-Columbian civilization and Spanish colonization history of Ecuador, we determined, for the first time, the possible centre of origin and migration events of the Nacional variety from the Amazonian area until its arrival in the coastal provinces. As large unexplored forest areas still exist in the southern part of the Ecuadorian Amazonian region, our findings could provide clues as to where precious new genetic resources could be collected, and subsequently used to improve the flavour and disease resistance of modern Ecuadorian cocoa varieties.

Background Tropical countries are thought to play an important role in the global behavior of respiratory infections such as influenza. The tropical country of Ecuador has almost no documentation of the causes of acute respiratory infections. The objectives of this study were to identify the viral agents associated with influenza like illness (ILI) in Ecuador, describe what strains of influenza were circulating in the region along with their epidemiologic characteristics, and perform molecular characterization of those strains. Methodology/Findings This is a prospective surveillance study of the causes of ILI based on viral culture of oropharyngeal specimens and case report forms obtained in hospitals from two cities of Ecuador over 4 years. Out of 1,702 cases of ILI, nine viral agents were detected in 597 patients. During the time of the study, seven genetic variants of influenza circulated in Ecuador, causing six periods of increased activity. There appeared to be more heterogeneity in the cause of ILI in the tropical city of Guayaquil when compared with the Andean city of Quito. Conclusions/Significance This was the most extensive documentation of the viral causes of ILI in Ecuador to date. Influenza was a common cause of ILI in Ecuador, causing more than one outbreak per year. There was no well defined influenza season although there were periods of time when no influenza was detected alternating with epidemics of different variant strains. PMID:21887216

The Economic Burden of Intimate Partner Violence in Ecuador: Setting the Agenda for Future Research and Violence Prevention Policies

Directory of Open Access Journals (Sweden)

Phaedra Corso

2013-08-01

Full Text Available Introduction: Intimate partner violence (IPV is a widespread social structural problem that affects a great proportion of Ecuadorian women. IPV is a sexually, psychologically, or physically coercive act against an adult or adolescent woman by a current or former intimate partner. Not-for-profit groups in Ecuador report that 70% of women experience 1 of the forms of IPV sometime during their lifetime, but population-based surveys suggest that 41% of Ecuadorian women are exposed to emotional violence, 31% physical violence, and 12% sexual violence by their spouse or partner over their lifetime. Despite the high prevalence, the response of the Ecuadorian government has been insufficient to reduce the number of victims and to provide adequate legal and health services for the prevention and treatment of IPV. Given the power of economic data to influence policy making, the goal of this study is to produce the first estimate of the economic impact of IPV in Ecuador and to identify the policy paths in which these estimates would have the greatest impact for Ecuador.Methods: Using a bottom-up method for estimating the economic burden of IPV and a national prevalence of IPV based on a population-based survey in the 2003–2004 year, the total economic burden is estimated at approximately $109 million adjusted to the 2012 United States (U.S. currency rate. Results: Based on a prevalence of 255,267 women who were victims of IPV in the 2003–2004 year, the total economic burden is estimated at approximately $109 million adjusted to the 2012 the U.S. currency rate. The largest cost category contributing to the economic burden was the costs of healthcare services to treat injuries associated with IPV events.Conclusion: The asymmetry between the economic burden of IPV and the amount of government resources devoted to IPV prevention efforts suggests the need for a greater role to be played by the government and other factors in society in the area of IPV

Full Text Available ABSTRACT Objective To analyse the nutritional status of the adult population in Esmeraldas by means of anthropometric measurements, the input of macro and micronutrients in the diet, and the adequacy estimation of nutrient intake by hispanic Dietary Reference Instakes along with the sex and the age influence. Methods Nutrient intake data were obtained by personal interview with the application of two 24 hour recalls (weekend and weekday. The anthropometric indicators analysed were body mass index, waist circumference and blood pressure. Nutriplato version 2.0 software was used for the two 24-hours food recall surveys data processing, and for the respective calculations of macronutrients, micronutrients and Dietary Reference Intakes. Means and standard deviations were calculated for anthropometry, nutrient intakes and Dietary Reference Instakes. The General Linear Model was applied to identify differences in relation to nutrient intakes considering sex, profession, body mass index, group, origin and day of the week as factors. Results Statistical analysis showed significant differences mainly in carbohydrates, fiber, calcium, phosphorus, iron, sodium, iodine, and vitamin E. Dietary intakes were compared with the Federación Española de Sociedades de Nutrición, Alimentación y Dietética Dietary Reference Intakes requirements and calcium, potassium, iodine, riboflavin, pantothenic acid, biotin, vitamin D, vitamin E, fiber, monounsaturated fatty acids and polyunsaturated fatty acids are below the Dietary Reference Instakes in all ages and gender subgroups. The anthropometric results obtained indicated that 67.0% of the population were overweight and obese, the 87.7% of the adults suffered from prehypertension and the waist circumference indicated that 73.0% of the subjects were established in the range of high risk of cardiovascular disease.

Since the nematodes Trichuris trichiura and T. suis are morphologically indistinguishable, genetic analysis is required to assess epidemiological cross-over between people and pigs. This study aimed to clarify the transmission biology of trichuriasis in Ecuador. Adult Trichuris worms were collected during a parasitological survey of 132 people and 46 pigs in Esmeraldas Province, Ecuador. Morphometric analysis of 49 pig worms and 64 human worms revealed significant variation. In discriminant analysis morphometric characteristics correctly classified male worms according to host species. In PCR-RFLP analysis of the ribosomal Internal Transcribed Spacer (ITS-2) and 18S DNA (59 pig worms and 82 human worms), nearly all Trichuris exhibited expected restriction patterns. However, two pig-derived worms showed a "heterozygous-type" ITS-2 pattern, with one also having a "heterozygous-type" 18S pattern. Phylogenetic analysis of the mitochondrial large ribosomal subunit partitioned worms by host species. Notably, some Ecuadorian T. suis clustered with porcine Trichuris from USA and Denmark and some with Chinese T. suis. This is the first study in Latin America to genetically analyse Trichuris parasites. Although T. trichiura does not appear to be zoonotic in Ecuador, there is evidence of genetic exchange between T. trichiura and T. suis warranting more detailed genetic sampling.

This paper reports on an investigation into the chronology of El Niño/Southern Oscillation (ENSO) events, during the period from the arrival of conquistadores in Ecuador in 1532 until the year 1900. A number of probable El Niño events and drought years can be dated from anecdotal reports of significant rainfall and drought in the equatorial region. The evidence of ENSO has been documented from early reports in the South America archives. A large number of books and articles have been reviewing from the Ecuadorian archives to obtain information on El Niño events that have occurred over the past centuries. This information is based on evidence obtained from the equatorial region, where strong and very strong El Niño events clearly separate the northern part of the Ecuadorian coast from the southern region, the normally rainy season specially from west-central to the south coast of Ecuador, as well as the drought years, reported in this region which is climatologically and oceanographically different from the moist Northern coast of Ecuador. Given the normal occurrence of rains in the southern coast of Ecuador, it is reasonable to expect that at least some of the major rainy seasons would be recorded in local chronicles and publications. This information has been compared with reports obtained from Peru. Relative strengths of events are based on such considerations as wind and current effects on travel times of ancient sailing ships, degree of physical damage and destruction, amounts of rainfall and flooding, human disease epidemic, mass mortality of endemic marine organism, rises in sea temperatures and sea levels, effects on coastal fisheries. This paper is the first survey of the historical sources concerned the rainfall and drought in Ecuador. In the course of this investigation we also noted some extended periods of time, near decadal or longer over the past records, when the amount and/or strength of El Niño and its resulting effects appeared to represent

On April 16th, 2016, Ecuador's coastal provinces were struck by a devastating earthquake with 7.8 Mw magnitude. This event caused the earthquake-related largest dead toll in Ecuador (663 fatalities) since 1987 inland event. It provoked also a widespread destruction of houses, hotels, hospitals, affecting economic activities. Damaged was very worthy in the city of Pedernales, one of the nearest localities to the epicenter. Rupture area extended about a 100 km from the southern limit marked by the aftershock area of the 1998, 7.1 Mw earthquake to its northern limit controlled by the Punta Galera-Mompiche seismic zone, which is one of the several elongated swarms oriented perpendicular to the trench that occurred since 2007. Historical accounts of the Ecuador Colombia subduction zone have few mentions of felt earthquakes in the XVIII and XIX century likely related to poor communication and urban settlements in this area. A cycle of noticeable earthquakes began in 1896, including the 1906 8.8 Mw event and three earthquakes with magnitudes larger than 7.7 in the period 1942-1979, that preceded the 2016 earthquake. The Instituto Geofiísico of the Escuela Politécnica Nacional (IGEPN) has been monitoring the coastal area through the National Seismic Network (RENSIG) since 30 years back and recently enhanced through SENASCYT and SENPLADES supported projects. International collaboration from Japanese JICA and French IRD also contributed to expand the network and implement research projects in the area. Nowadays, the RENSIG has 135 seismic stations including 105 broadband and 5 strong motion velocimeters. Processing performed by Seiscomp3 software allows an automatic distribution of seismic parameters. A joint cooperation between IGEPN, the Navy Oceanographic Institute and the National Department for Risk Management is in charge of tsunami monitoring.

Prevalence of cerebral microbleeds (CMB) in white and Asian populations range from 4% to 15%. However, there is no information from indigenous Latin American people. We aimed to assess prevalence and cerebrovascular correlates of CMB in stroke-free older adults living in rural Ecuador. Of 311 Atahualpa residents aged ≥60 years identified during a door-to-door survey, 258 (83%) underwent brain magnetic resonance imaging. Twenty-one were further excluded for a diagnosis of overt stroke. Using multivariate logistic regression models, adjusted for demographics and cardiovascular risk factors, we evaluated whether CMB were independently associated with silent strokes, white matter hyperintensities, and global cortical atrophy. Twenty-six (11%) of 237 participants had CMB, which were single in 54% of cases. CMB were deep in 11 patients, cortical in 9, and located both deep and cortical in 6. In univariate analyses, CMB were associated with age, systolic blood pressure, moderate-to-severe white matter hyperintensities, silent lacunar infarcts, and cortical atrophy. Mean (±SD) values for systolic blood pressure were 155±27 mm Hg in patients who had CMB versus 142±26 mm Hg in those who did not (P=0.017). In the adjusted models, moderate-to-severe white matter hyperintensities (P=0.009), silent lacunar infarcts (P=0.003), and global cortical atrophy (P=0.04) were independently associated with CMB. Prevalence of CMB in stroke-free older adults living in Atahualpa is comparable with those reported from other ethnic groups. There is a strong relationship between CMB and increased age, high systolic blood pressure, silent markers of cerebral small vessel disease, and cortical atrophy. © 2015 American Heart Association, Inc.

Full Text Available Abstract Pastaza is the largest and least populated province in Ecuador, with seven native indigenous nationalities. The Kichwas from the Rio Chico community live near to the capital city Puyo, are recognized for their knowledge on stingless honey bees. From the 400 species of Neotropical Meliponini that make honey in cerumen pots, almost 100 thrive in Southern Ecuador, and confer such biodiversity to pot-honey. In this study sensory characteristics of Ecuadorian false and genuine honeys with diverse entomological origin: Apis mellifera – light amber and amber, Geotrigona leucogastra, Melipona grandis and Scaptotrigona sp. (S. ederi np Schwarz were investigated with Kichwa assessors (four female and four male, aged 18–62 years old. The panel was asked to taste and to identify sensory attributes of honey (appearance, taste, smell, aroma, mouthfeel, other tactile sensations, and to score their intensities in 10 cm unstructured line scales anchored with the words weak and strong, using the Free-Choice Profile methodology The Generalized Procrustes Analysis was used on the data. The first and second dimensions accounted for by 61.1% of the variance. In the descriptive sensory evaluation, darker honeys (amber A. mellifera, false and Geotrigona were separated from (light amber A. mellifera, Melipona and Scaptotrigona by the first dimension; whereas thicker honeys (A. mellifera and false were discriminated from thinner honeys (Geotrigona, Melipona and Scaptotrigona by the second dimension. The assessors were able to evaluate and differentiate honey types without previous sensory training. Remarkably, two Kichwa ladies immediately spit out the false honey, in contrast to an acceptance study on 18-honeys, where the false honey was scored among the preferred ones by 58 participants of the First Congress on Apiculture and Meliponiculture in Ecuador. Therefore, results suggest that Ecuadorian native Kichwas keep a sensory legacy of ancestral knowledge

Full Text Available The migration pattern between Ecuador and Spain has undergone changes since the start of the 2008 crisis. A slowdown in inflows to Spain and increasing Ecuadorian returnees, today add the Spanish skilled migration to this country in entering higher education as well as the exit of young Ecuadorians to acquire fourth level´s degree in Spain, or Europe in general. The context of crisis and unemployment in education in Spain and education reform policies being carried out in Ecuador is articulated in shaping this circularity between the two countries. Through a quantitative and qualitative multi-situated methodology based on a poll and in-depth interviews, this paper estimates the volume of these displacements and explores the motivations, conditions and strategies that are influencing.

The traditional markets in southern Ecuador and within the Andean region are especially important for plant resource trading among local people, even since before Spanish colonization; therefore, ethnobotanical studies are currently necessary and important. These strategic spaces persist for the traditional medicine cultural value reflected in the higher consumption of medicinal plants, which span all socioeconomic levels of rural and urban people. The purpose of this study includes the following: 1) to create a novel list of medicinal plants sold at 33 traditional markets; 2) to establish medicinal plant use agreement amongst vendors with the Factor of Informant Consensus (FIC); and 3) to determine the most sold medicinal plant species using the Fidelity Level (FL). This study focus on traditional markets ethnobotany utilizes the largest sample of medicinal plants market vendors up to date in Ecuador, interviewing them at 33 traditional markets, located within the Loja province. In order to determine the most sold medicinal plants and their ethnobotanical information, structured questionnaires and personal conversations were conducted with 196 medicinal plant vendors, and voucher specimens were created. Agreement among vendors about the therapeutic use of medicinal plants was measured using the FIC, and the most sold medicinal plant species were assessed with the FL. This research registered 160 medicinal plant species, grouped in 126 genera and 57 families that were sold in 33 traditional markets. The uses of medicinal plants in southern Ecuador are related to a long history of traditional medicine health practices that has persisted until today as well as high plant diversity. The 53 therapeutic uses recorded were grouped into 12 medical categories that were adapted from the World Health Organization. Three medical categories shared the highest value for FIC = 0.92, which showed a high level of agreement of market vendors for 57 medicinal plant species sold

The Ecuadorian crust is a mosaic of NNE-SSW-trending terranes representing different geotectonic domains. These terranes, composed by oceanic and continental crust, were formed during the Triassic separation of the North and South American continents and were accreted to the Amazon craton during subduction of the Farallon/Nazca plate, from Early Cretaceous to Early Tertiary (Litherland et al., 1994). In the southwestern part of Ecuador, EW-striking crustal-scale faults, related to the Huancabamba deflection, mark the transition between the Central and Northern Andes. In this study we discuss more than 200 lead isotope compositions of ores as well as magmatic and metamorphic rocks of Ecuador. The interest of carrying out a large-scale isotope survey in the Northern Andes derives from a geotectonic evolution characterized by multi-accretionary episodes which is not recognized in the Central Andes (au)

Insight into the wild origin, migration and domestication history of the fine flavour Nacional Theobroma cacao L. variety from Ecuador.

Directory of Open Access Journals (Sweden)

Rey Gaston Loor Solorzano

Full Text Available Ecuador's economic history has been closely linked to Theobroma cacao L cultivation, and specifically to the native fine flavour Nacional cocoa variety. The original Nacional cocoa trees are presently in danger of extinction due to foreign germplasm introductions. In a previous work, a few non-introgressed Nacional types were identified as potential founders of the modern Ecuadorian cocoa population, but so far their origin could not be formally identified. In order to determine the putative centre of origin of Nacional and trace its domestication history, we used 80 simple sequence repeat (SSR markers to analyse the relationships between these potential Nacional founders and 169 wild and cultivated cocoa accessions from South and Central America. The highest genetic similarity was observed between the Nacional pool and some wild genotypes from the southern Amazonian region of Ecuador, sampled along the Yacuambi, Nangaritza and Zamora rivers in Zamora Chinchipe province. This result was confirmed by a parentage analysis. Based on our results and on data about pre-Columbian civilization and Spanish colonization history of Ecuador, we determined, for the first time, the possible centre of origin and migration events of the Nacional variety from the Amazonian area until its arrival in the coastal provinces. As large unexplored forest areas still exist in the southern part of the Ecuadorian Amazonian region, our findings could provide clues as to where precious new genetic resources could be collected, and subsequently used to improve the flavour and disease resistance of modern Ecuadorian cocoa varieties.

Rhipicephalus microplus is widely distributed in tropical and subtropical areas of the world where livestock is a principal activity with great veterinary and economic importance. In Ecuador, this hematophagous ectoparasite has been observed between 0 and 2600 masl. One of the main tick control measures is the use of acaricides, which have been indiscriminately used worldwide and in Ecuador. In this country, no studies on acaricide resistance in Rhipicephalus microplus have been published. The current study aims to characterise the level of resistance of R. microplus against three main acaricides commonly used in Ecuador i.e. amitraz, alpha-cypermethrin and ivermectin to determine the level and pattern of dose-responses for R. microplus in 12 field populations (farms). The level of acaricide resistance was evaluated using three different bioassays: adult immersion test (AIT), larval package test (LPT) and larval immersion test (LIT), as recommended by the FAO. The predictive dose-responses were analysed by binomial logistics regression of the larval survival rate (resistance). In general, we found resistance of 67% for amitraz; 50% for alpha-cypermethrin and from 25 to 42% for ivermectin in the twelve field populations analysed. Resistance levels were studied in larval and adult bioassays, respectively, which were slightly modified for this study. For larval bioassays based on corrected mortality i.e. high (above 51%), medium (21–50%) and low (11–20%) resistance, percentages less than 10% were considered as susceptible. For the adult test, two resistance levels were used i.e. high (more than 76%) and medium (51 to 75%) resistance. Percentages lower than 50% were considered as susceptible. In this context, for larval bioassays, amitraz showed 21%, 38% and 8% for high, medium and low resistance, respectively. Alpha-cypermethrin presented 8%, 4 and 38% for high, medium and low resistance, respectively. Ivermectin presented 8%, 25% and 8% for high, medium and low

Abstract A new species of Pristimantis is described from the highland paramos on the eastern slopes of the Cajas Massif, southern Andes of Ecuador, at 3400 m. This new species is characterized by having a distinctive reddish color, cutaneous macroglands in suprascapular region and surfaces of arm and legs, and by lacking dentigerous processes of vomers. The cutaneous macroglands are similar to those exhibited by several species of the Pristimantis orcesi group, and may suggest a close phylogenetic relationship. The new species could be a latitudinal substitution of Pristimantis orcesi in the southern Andes of Ecuador. PMID:29713233

For 11 years, a 38-year-old male residing in a subtropical region of Ecuador, was repeatedly diagnosed with chronic anemia, and treated with blood transfusions in a hospital of province of Cotopaxi, Ecuador. He was transferred to Quito for severe anemia, having hemoglobin of 4 g/dL. Duodenoscopy was performed and adult nematodes, identified later as Ancylostoma duodenale, were observed. The patient was successfully treated with albendazole for five consecutive days and given blood transfusions. In the control visit at eight months, without anemia and no hookworm ova in the stool examined were found.

. Vegetation cover in the area of Santa Elena should have been extensive, and even more so in the Guayas and Guayabamba valleys. The newly densely vegetated areas, and fluvial barriers, transformed the refugia into lethal traps for large animals already under biological stress, such as were mastodons, ground sloths and equids. Within the megafauna, only tapirs and artiodactyla (Cervidae and Camelidae) survived. In our opinion, the most suitable model to justify the great crisis of the mammal megafauna at the Pleistocene/Holocene transition, also in areas out of Ecuador, must be mainly based on the three parameters: high aridity, high humidity and geographic factors.

El Niño-Southern Oscillation and dengue early warning in Ecuador

Science.gov (United States)

Stewart, A. M.; Lowe, R.

2012-04-01

Dengue fever, a mosquito-borne viral disease, is one of the most important emerging tropical diseases. Dengue is hyper-endemic in coastal Ecuador, where all four serotypes co-circulate. The El Niño-Southern Oscillation (ENSO) influences climate in Ecuador, with positive phase ENSO (El Niño) associated with wetter and warmer conditions over the southern coastal region. In turn, greater rainfall increases the availability of mosquito breeding sites for the dengue mosquito (Aedes aegypti), while warmer temperatures increase rates of larval development, mosquito biting, and viral replication in the mosquito. We report a statistical model for assessing the importance of climate as a driver for inter-annual variability in dengue fever in southern coastal Ecuador. Climate variables from a local meteorology station (precipitation, number of rainy days, minimum/maximum/mean air temperature), combined with gridded climate products, and anomalies of Pacific sea surface temperatures (Oceanic Niño Index, ONI) were used to predict monthly dengue standardized morbidity ratios (SMR) (1995-2010). Non-climatic confounding factors such as serotype introduction and vector control effort were also considered. Preliminary results indicated a statistically significant positive association between dengue risk and the number of rainy days during the previous month. Both the number of rainy days and dengue SMR were positively associated with the Pacific SST anomalies with a lead time of several months. Due to time lags involved in the climate-disease transmission system, monitoring El Niño / La Niña evolution in the Pacific Ocean could provide some predictive lead time for forecasting dengue epidemics. This is the first study of dengue fever and climate in this region. This research provides the foundation to develop a climate-driven early warning system for dengue fever in Ecuador.

Full Text Available Introduction: This article aims to quantify racial discrimination in the labor market in Ecuador between 2010 and 2012. Methodology: Information is collected from quarterly household surveys on employment prepared by the National Institute of Statistics and Census of Ecuador, from which Mincer equations are estimated for labor income per hour. Subsequently, the Oaxaca-Blinder decomposition with Heckman correction is used to determine wage gaps attributable to observable and unobservable factors regarding two ethnic groups: mestizos and whites. Results: The wage gap is significant and positive for white people, and it increases during the period of analysis. 40 % of this difference is due to higher provisions in human capital. However, about 42 % of the gap remains unexplained.

Es un primer paso positivo, aunque las recomendaciones son meramente simples invitaciones o “música celestial”, al carecer de un carácter vinculatorio u obligatorio para los empresarios, directores y accionistas de control. Dichas recomendaciones solo se convierten en mandato para aquellas compañías que las implementen en sus estatutos sociales; pero aún ésta protección es muy débil, puesto que nada impide a que el accionista de control o una simple mayoría de socios reforme los estatutos a su conveniencia cuando lo estime conveniente a su gusto o arbitrio, para incumplir las disposiciones estatutarias. Incluso en Ecuador, donde la violación de las normas estatutarias no es sancionada, ya que con los actuales medios disponibles a los accionistas de minoría es casi imposible iniciar una acción judicial, es imperioso gozar de legitimidad activa para demandar a la sociedad; no hablemos si quiera de demandar a los accionistas de control. En materia de mercado de valores, Ecuador todavía está “en pañales” frente a otros países latinoamericanos, no hablar siquiera de mercados más desarrollados. Una adecuada regulación normativa de la legislación societaria y de mercado de valores, encaminada a la protección de los accionistas minoritarios, en resumen, un mejor gobierno corporativo, lo cual otorgaría mayores incentivos para ampliar y desarrollar el mercado de capitales.

The Hash security algorithm was analyzed in order to mitigate information security in a distributed architecture. The objective of this research is to develop a prototype for the Adoption of the algorithm Hash in a conceptual model for the Civil Registry of Ecuador. The deductive method was used in order to analyze the published articles that have a direct relation with the research project "Algorithms and Security Protocols for the Civil Registry of Ecuador" and articles related to the Hash security algorithm. It resulted from this research: That the SHA-1 security algorithm is appropriate for use in Ecuador's civil registry; we adopted the SHA-1 algorithm used in the flowchart technique and finally we obtained the adoption of the hash algorithm in a conceptual model. It is concluded that from the comparison of the DM5 and SHA-1 algorithm, it is suggested that in the case of an implementation, the SHA-1 algorithm is taken due to the amount of information and data available from the Civil Registry of Ecuador; It is determined that the SHA-1 algorithm that was defined using the flowchart technique can be modified according to the requirements of each institution; the model for adopting the hash algorithm in a conceptual model is a prototype that can be modified according to all the actors that make up each organization.

Climatic variability related to El Niño in Ecuador − a historical background

Full Text Available This paper reports on an investigation into the chronology of El Niño/Southern Oscillation (ENSO events, during the period from the arrival of conquistadores in Ecuador in 1532 until the year 1900. A number of probable El Niño events and drought years can be dated from anecdotal reports of significant rainfall and drought in the equatorial region. The evidence of ENSO has been documented from early reports in the South America archives. A large number of books and articles have been reviewing from the Ecuadorian archives to obtain information on El Niño events that have occurred over the past centuries. This information is based on evidence obtained from the equatorial region, where strong and very strong El Niño events clearly separate the northern part of the Ecuadorian coast from the southern region, the normally rainy season specially from west-central to the south coast of Ecuador, as well as the drought years, reported in this region which is climatologically and oceanographically different from the moist Northern coast of Ecuador. Given the normal occurrence of rains in the southern coast of Ecuador, it is reasonable to expect that at least some of the major rainy seasons would be recorded in local chronicles and publications. This information has been compared with reports obtained from Peru. Relative strengths of events are based on such considerations as wind and current effects on travel times of ancient sailing ships, degree of physical damage and destruction, amounts of rainfall and flooding, human disease epidemic, mass mortality of endemic marine organism, rises in sea temperatures and sea levels, effects on coastal fisheries. This paper is the first survey of the historical sources concerned the rainfall and drought in Ecuador. In the course of this investigation we also noted some extended periods of time, near decadal or longer over the past records, when the amount and/or strength of El Niño and its resulting effects

We describe the subsistence exploitation of an entire turtle fauna in Esmerald's Province, Ecuador. We collected first hand accounts and witnessed a number of capture techniques used by rural afroecuadorian and chachi inhabitants of the Cayapas Santiago River basin. The diversity of techniques indicated a practical knowledge of the ecology of the species. Chelydra acutirostris, Kinosternon leucostomum, Rhinoclemmys annulata, Melanosterna, and R. nasuta were captured and eaten. Poziando involved cleaning pools in a stream bed during the relatively dry season by removing live plants, organic detritus, and then seining with baskets; we observed R. melanosterna and K. leucostomum captured in this way. Pitfall traps baited with fruit were used to catch R. melanosterna during forays on land. Basket traps (Canasto tortuguero) with a wooden slat funnel across the opening are floated with balsa lashed to the sides. Banana or Xanthosoma leaf bait in the basket traps caught R. melanosterna, R. nasuta, and K. leucostomum. Marshy areas were probed for R. melanosterna and K. leucostomum. Direct capture by hand was also common. Turtles were relished as food items; all turtles captured were consumed, usually in soup or stew. Use of turtles for food in the region was pervasive, perhaps because fish and game populations were depleted.

Full Text Available ABSTRACT Estimating population parameters is essential for understanding the ecology of species, which ultimately helps to assess their conservation status. The seahorse Hippocampus reidi is directly exposed to anthropogenic threats along the Brazilian coast, but the species still figures as Data Deficient (DD at IUCN’s Red List. To provide better information on the ecology of this species, we studied how population parameters vary over time in a natural subtropical environment. By combing mark-recapture models for open and closed populations, we estimated abundance, survival rate, emigration probability, and capture probability. We marked 111 individuals, which showed a 1:1 sex ratio, and an average size of 10.5 cm. The population showed high survival rate, low temporary emigration probability and variable capture probability and abundance. Our models considering relevant biological criteria illuminate the relatively poorly known population ecology and life history of seahorses. It is our hope that this study inspires the use of mark-recapture methods in other populations of H. reidi in a collective effort to properly assess their conservation status.

The Chacana caldera, located immediately east of Quito, capital of Ecuador, forms the most-northern edifice of Ecuadoros rhyolite province. It is a 50X30 km Pleistocene structure that has remained active into historic times. Vitrophyres, welded tuffs, and ignimbrites of rhyolitic and dacitic composition constitute the outer flanks, meantime syngenetic breccias and tuffs, capped later by extensive dacite lava flows and basin sediments, filled the calderaos depression. A notable resurgence occurred that lifted quiet-water sediments to over 4000 m in elevation. The area has numerous hot springs, and little seismic activity.

Individuals with disabilities experience inequities in access to health care, education, employment, and social inclusion. Causes for Change International (CCI), a non-governmental Organization (NGO), using a community-based rehabilitation approach has worked for 20 years to build self-sufficiency, improve health-care services, and education for women, children, and persons with disabilities in Ecuador. CCI initially addressed health; advocacy for individuals with disabilities; and promoted educational opportunities for children with disabilities, starting in one rural community. CCI's outreach has expanded through Ecuador's coastal provinces, Andean provinces, and Galapagos Islands. CCI also focused on local health-care workforce development, developing employment skills for individuals with disabilities and social inclusion for this population. CCI collaborated with local organizations, government, and universities to provide resources, managed by local leadership. Key program elements of the CCI approach include (1) develop trust between CCI, local communities, local agencies, and government; (2) empower local groups to assume leadership and sustain programs; (3) support communities and groups invested in developing self-sufficiency; and (4) strengthen collaborations and partnerships between local and international organizations, universities, and government agencies. Key lessons learned by CCI are to be supportive of cultural differences; understand that limited financial and material resources may limit the program development; recognize that it is difficult not to foster dependent relationships with communities and appreciate the importance of working with and within the host country's governmental systems. CCI is expanding its service base to other regions of Ecuador and is focusing on development of the Ecuadorian health-care workforce and social inclusion opportunities for individuals with disability. The efforts of a small NGO have helped build

In Ecuador, Tapirus pinchaque is considered to be critically endangered. Although the species has been registered in several localities, its geographic distribution remains unclear, and the effects of climate change and current land uses on this species are largely unknown. We modeled the ecological niche of T. pinchaque using MaxEnt, in order to assess its potential adaptation to present and future climate change scenarios. We evaluated the effects of habitat loss due by current land use, the ecosystem availability and importance of Ecuadorian System of Protected Areas into the models. The model of environmental suitability estimated an extent of occurrence for species of 21,729 km2 in all of Ecuador, mainly occurring along the corridor of the eastern Ecuadorian Andes. A total of 10 Andean ecosystems encompassed ~98% of the area defined by the model, with herbaceous paramo, northeastern Andean montane evergreen forest and northeastern Andes upper montane evergreen forest being the most representative. When considering the effect of habitat loss, a significant reduction in model area (~17%) occurred, and the effect of climate change represented a net reduction up to 37.86%. However, the synergistic effect of both climate change and habitat loss, given current land use practices, could represent a greater risk in the short-term, leading to a net reduction of 19.90 to 44.65% in T. pinchaque’s potential distribution. Even under such a scenarios, several Protected Areas harbor a portion (~36 to 48%) of the potential distribution defined by the models. However, the central and southern populations are highly threatened by habitat loss and climate change. Based on these results and due to the restricted home range of T. pinchaque, its preference for upland forests and paramos, and its small estimated population size in the Andes, we suggest to maintaining its current status as Critically Endangered in Ecuador.

2015-11-01

The aim of this study was to investigate the prevalence of Vibrio spp. in shrimp at retail and in shrimp farms in Ecuador and to determine the antimicrobial agent resistance patterns of farm isolates. The presence of genes linked to early mortality syndrome (EMS) or acute hepatopancreatic necrosis disease (AHPND) also was evaluated. Vibrio spp. were isolated from retail shrimps in Cuenca, Ecuador, and farm shrimps originating from provinces El Oro and Guayas, Ecuador. A total of 229 shrimp samples were collected, of which 71 originated from retail markets in Cuenca and 158 came from shrimp farms. Overall, 219 (95.6%) samples tested positive for Vibrio spp. Vibrio parahaemolyticus (80.8%) was the most common species detected, followed by Vibrio alginolyticus (50.2%), Vibrio cholerae (11.3%), and Vibrio vulnificus (3.5%). None of the V. parahaemolyticus isolates carried the virulence-associated tdh and trh genes. In V. parahaemolyticus shrimp farm isolates, high resistance was found to ampicillin (92.2%), and intermediate resistance was found to tetracycline (51.3%) and amikacin (22.1%). Of the V. parahaemolyticus strains, 68 were resistant to at least three antimicrobial agents, and 2 were resistant to seven antimicrobial agents simultaneously. Up to 18 resistant isolates were found for V. alginolyticus, whereas V. vulnificus and V. cholerae isolates were more susceptible. None of the V. parahaemolyticus isolates carried the EMS-AHPND plasmid. The results of this study revealed the ubiquitous occurrence of Vibrio spp. in shrimps at retail and on shrimp farms in Ecuador.

Full Text Available After the 7.8 Mw Earthquake occurred in Ecuador on April 16 of 2016, the Ecuadorian Government declared the whole Island of Muisne into a risk hazard zone by a potential Tsunami impact and subsequent flooding. Based on the emitted resolution, human settlements in the affected area were prohibited, and a resettlement project in the village of Bunche is currently taking place. Nonetheless, our study demonstrates that the inundation chart used to release the mentioned resolution underestimate the flooding area in case of a real Tsunami impact. To support this conclusion, we present a new inundation chart for the three more probable scenarios, based on historical tsunami records and a seismic hazard assessment study in central coastal Ecuador.

Epidemiology of leishmaniasis in Ecuador: current status of knowledge - A review

Full Text Available Although leishmaniasis is regarded as a significant health problem in Ecuador by the Ministry of Health, and the incidence has increased over the last years, an official map on the geographic distribution of disease and sand fly vectors or a control strategy do not exist yet. This article reviews the current situation based on published information to improve our knowledge and understand the epidemiological situation of leishmaniasis in Ecuador in order to help future research and to develop a national control strategy. The disease is endemic in most provinces throughout Pacific coastal region, Amazonian lowlands, and some inter-Andean valleys with a total 21,805 cases reported during 1990-2003. Whereas cutaneous leishmaniasis (CL is found throughout Ecuador, mucocutaneous leishmaniasis (MCL appears to be restricted to the Amazon region; one, parasitologically unconfirmed case of visceral form was reported in 1949. Most human infections are caused by Leishmania (Viannia spp., which is distributed in the subtropical and tropical lowlands; infections due to L. (Leishmania spp. are found in the Andean highlands and in the Pacific lowlands as well. The proven vectors are Lutzomyia trapidoi and Lu. ayacuchensis. Canis familiaris, Sciurus vulgaris, Potos flavus, and Tamandua tetradactyla have been found infected with Leishmania spp. It is estimated that around 3000-4500 people may be infected every year, and that 3.1 to 4.5 millions people are estimated to be at risk of contracting leishmaniasis.

Dengue vector dynamics (Aedes aegypti influenced by climate and social factors in Ecuador: implications for targeted control.

Directory of Open Access Journals (Sweden)

Anna M Stewart Ibarra

Full Text Available BACKGROUND: Dengue fever, a mosquito-borne viral disease, is now the fastest spreading tropical disease globally. Previous studies indicate that climate and human behavior interact to influence dengue virus and vector (Aedes aegypti population dynamics; however, the relative effects of these variables depends on local ecology and social context. We investigated the roles of climate and socio-ecological factors on Ae. aegypti population dynamics in Machala, a city in southern coastal Ecuador where dengue is hyper-endemic. METHODS/PRINCIPAL FINDINGS: We studied two proximate urban localities where we monitored weekly Ae. aegypti oviposition activity (Nov. 2010-June 2011, conducted seasonal pupal surveys, and surveyed household to identify dengue risk factors. The results of this study provide evidence that Ae. aegypti population dynamics are influenced by social risk factors that vary by season and lagged climate variables that vary by locality. Best-fit models to predict the presence of Ae. aegypti pupae included parameters for household water storage practices, access to piped water, the number of households per property, condition of the house and patio, and knowledge and perceptions of dengue. Rainfall and minimum temperature were significant predictors of oviposition activity, although the effect of rainfall varied by locality due to differences in types of water storage containers. CONCLUSIONS: These results indicate the potential to reduce the burden of dengue in this region by conducting focused vector control interventions that target high-risk households and containers in each season and by developing predictive models using climate and non-climate information. These findings provide the region's public health sector with key information for conducting time and location-specific vector control campaigns, and highlight the importance of local socio-ecological studies to understand dengue dynamics.

Ethnicity, development and gender: Tsáchila indigenous women in Ecuador.

Science.gov (United States)

Radcliffe, Sarah; Pequeño, Andrea

2010-01-01

In recent decades, indigenous populations have become the subjects and agents of development in national and international multicultural policy that acknowledges poverty among indigenous peoples and their historic marginalization from power over development. Although the impact of these legal and programmatic efforts is growing, one persistent axis of disadvantage, male–female difference, is rarely taken into account in ethno-development policy and practice. This article argues that assumptions that inform policy related to indigenous women fail to engage with indigenous women's development concerns. The institutional separation between gender and development policy (GAD) and multiculturalism means that provisions for gender in multicultural policies are inadequate, and ethnic rights in GAD policies are invisible. Drawing on post-colonial feminism, the paper examines ethnicity and gender as interlocking systems that structure indigenous women's development experiences. These arguments are illustrated in relation to the case of the Tsáchila ethno-cultural group in the South American country of Ecuador.

Cytological and isoenzyme analysis of the Bucay and Quevedo cytotypes of the onchocerciasis vector Simulium exiguum (Diptera: Simuliidae in Ecuador

1993-03-01

Full Text Available Four cytotypes of Simulium exiguum occur in Ecuador, where this morphospecies is the primary vector of onchocerciasis. In this paper, we give the first full description of the banding pattern of the larval polytene chromosomes of the Quevedo cytotypes differ from the chromosomal standard sequence (of the Cayapa cytotype by the fixed inversions IIL-5 and IIL-6. The Quevedo cytotype additionally differs from the standard and Bucay cytotypes by processing a differentiated X chromosome, wich is indicated by the inversion IIS-A. As the degree of reproductive isolation between the Bucay and Quevedo cytotypes has not yet been estabilished, they must be regarded as intraspecific variants of the same species. In fact, isoenzyme characterizations showed that the Bucay and Quevedo cytotypes are differentiated only to the extent expected of incipient species or geographical populations. Moreover, the sibiling species status previously given to the Bucay cytotype needs be reassessed, there being inadequate analysis from areas in Ecuador where Bucay occurs in sympatry with the standard Cayapa cytotype. No isoenzyme electromorphs were discovered that identified all or mostadult females of any one (cytotype-pure collection.

To determine the predictors and prevalence of metabolic syndrome (MS) and the presence of vascular inflammation in apparently-normal children (10-15 years) of both sexes in Guayaquil, Ecuador. We included 395 apparently-healthy students from a middle-income school in a cross-sectional survey. Informed consent was obtained from students and parents. Anthropometric measurements including blood pressure (BP), body mass index (BMI) and waist-to-height ratio (WHtR), and blood tests were recorded. Vascular inflammation parameters were assessed. Percentiles of the different parameters were used, and MS was defined according to National Cholesterol Education Program Adult Treatment Panel III criteria (NCEP-ATPIII). Waist circumference>P 75, blood pressure>P 90, glucose>100mg/dl, triglycerides>100mg/dl, HDL100mg/dl were present in 70% of subjects with MS. The WHtR threshold≥0.5 was 100% sensitive in both sexes (67% specificity in boys and 69% in girls). There were significant associations between the WHtR and pre-hypertension and sedentary lifestyle (P<0.001 and P<0.003 respectively). A WHtR value of ≥0.50 indicated a 2.2-fold increased risk of MS compared with normal WHtR, and normal weight. A WHtR≥0.5 was 100% sensitive in detecting MS in 10-15 year-old boys and girls in the normal or overweight range of the BMI. This assessment is a simple and practical tool for use in population-based studies of cardiovascular risk. When combined with pre-hypertension and a sedentary lifestyle, the WHtR is highly sensitive in predicting MS. Copyright © 2017 SEH-LELHA. Publicado por Elsevier España, S.L.U. All rights reserved.

The mean distance between birthplaces of spouses (sigma, sigma'), the proportion of medium migrations (k), and the effective migration pressure (M(e)) have considerably increased, and the linear systematic pressure coefficient (b) has decreased in the human population of the Central Chernozem region during the past 50 years. However, the local inbreeding level (a), which is determined by both an increase in the migration intensity and a decrease in the effective population size (N(e)), has remained practically unchanged. A change in the regional administrative structure has affected the genetic structure of populations. In the 1950s, raions (administrative districts) of Kursk and Voronezh oblasts (regions) were similar with respect differentiation parameters, whereas the oblasts considerably differed from each other. At present, some Malecot's isolation-by-distance parameters for the populations of the districts that were included to Belgorod oblast in 1954 are lower and similar to those for the districts that remain in Kursk and Voronezh oblasts.

The aim of this study was to assess the possible mismatch of obstetrical skills between the training offered in Ecuadorian medical schools and the tasks required for compulsory rural service. Primary care, rural health centres in Southern Ecuador. A total of 92 recent graduated medical doctors during their compulsory rural year. A web-based survey was developed with 21 obstetrical skills. The questionnaire was sent to all rural doctors who work in Loja province, Southern Ecuador, at the Ministry of Health (n=92). 'importance of skills in rural practice' with a five-point Likert-type scale (1= strongly disagree; 5= strongly agree); and 'clerkship experience' using a nominal scale divided in five levels: level 1 (not seen, not performed) to level 5 (performed 10 times or more). Spearman's rank correlation coefficient (r) was used to observe associations. A negative correlation was found in the skills: 'episiotomy and repair', 'umbilical vein catheterisation', 'speculum examination', 'evaluation of cervical dilation during active labour', 'neonatal resuscitation' and 'vacuum-assisted vaginal delivery'. For instance 'Episiotomy and repair' is important (strongly agree and agree) to 100% of respondents, but in practice, only 38.9% of rural doctors performed the task three times and 8.3% only once during the internship, similar pattern is seen in the others. In this study we have noted the gap between the medical needs of populations in rural areas and training provided during the clerkship experiences of physicians during their rural service year. It is imperative to ensure that rural doctors are appropriately trained and skilled in the performance of routine obstetrical duties. This will help to decrease perinatal morbidity and mortality in rural Ecuador. Published by the BMJ Publishing Group Limited.

Full Text Available Genetic resources of Coffea canephora have been introduced in several tropical countries with potential for crop development. In Ecuador, the species has been cultivated since the mid-20th century. However, little is known about the diversity and genetic structure of introduced germplasm. This paper provides an overview of the genetic and phenotypic diversity of C. canephora in Ecuador and some proposals for implementing a breeding program. Twelve SSR markers were used to analyze 1491 plants of C. canephora grown in different living collections in Ecuador, compared to 29 genotypes representing the main genetic and geographic diversity groups identified within the species. Results indicated that most of the genotypes introduced are of Congolese origin, with accessions from both main subgroups, SG1 and SG2. Some genotypes were classed as hybrids between both subgroups. Substantial phenotypic diversity was also found, and correlations were observed with genetic diversity. Ecuadorian Robusta coffee displays wide genetic diversity and we propose some ways of improving Robusta in Ecuador. A breeding program could be based on three operations: the choice of elite clones, the introduction of new material from other countries (Ivory Coast, Uganda, and the creation of new hybrid material using genotypes from the different diversity groups.

Developing, testing and implementing evidence-based prevention interventions are important in decreasing substance use and sexual risk behavior among adolescents. This process requires research expertise, infrastructure, resources and decades of research testing, which might not always be feasible for low resource countries. Adapting and testing interventions proven to be efficacious in similar cultures might circumvent the time and costs of implementing evidence-based interventions in new settings. This paper describes the two-phase study, including training and development of the research infrastructure in the Ecuadorian university necessary to implement a randomized controlled trial. Familias Unidas is a multilevel parent-centered intervention designed in the U.S. to prevent drug use and sexual risk behaviors in Hispanic adolescents. The current study consisted of Phase 1 feasibility study (n=38) which adapted the intervention and study procedures within a single-site school setting in an area with a high prevalence of drug use and unprotected sexual behavior among adolescents in Ecuador, and Phase 2 randomized controlled trial of the adapted intervention in two public high schools with a target population of families with adolescents from 12 to 14 years old. The trial is currently in Phase 2. Study recruitment was completed with 239 parent-youth dyads enrolling. The intervention phase and the first follow-up assessment have been completed. The second and third follow-up assessments will be completed in 2016. This project has the potential of benefitting a large population of families in areas of Ecuador that are disproportionally affected by drug trafficking and its consequences.

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.

Santiago Ortiz Crespo

2013-12-01

Full Text Available Since 2006 the indigenous political vote has split between Pachakutik and Alianza País (AP. The latter is a political movement led by Rafael Correa, currently president of Ecuador. The article seeks an explanation for this distribution of the vote, examining the political behavior of the indigenous people of the Otavalo and Cotacachico unties of the northern Ecuadorean highlands. It argues that the support for Correa can be explained by several factors: (1 the historical relationship between indigenous people and the State; (2 an electoral behaviour that combines trust in ethnic leaders and pragmatism; and (3 an expectation of «more state presence». The study is based on two surveys of leaders and local population, participant observation and interviews, as well as a document review.

Egüez-Guevara, Pilar; Andrade, Flávia Cristina Drumond

2015-01-01

Knowledge on disability's impact among older women and men in Ecuador is limited. This paper provides gender-specific estimates of disability prevalence, life expectancy with and without disability, and the factors associated with gender differences in disability at older age in Ecuador (2009-2010). Data from the Health, Well-Being, and Aging Survey (SABE) Ecuador 2009 was used. Participants were 4480 men and women aged 60 and over. Life expectancy with and without disability was calculated using the Sullivan method. Logistic regression analyses were used to explore gender differences in disability prevalence. Two disability measures, indicating limitations in activities of daily living (ADL) and instrumental activities of daily living (IADL), were used. 60-year-old women in Ecuador can expect to live 16.3 years without ADL limitations compared to 16.9 years for men. Life expectancy without IADL limitations was 12.5 years for women and 15.5 years for men. At age 60, women's length of life with ADL and IADL disability was higher (7.9 years for women vs. 4.9 years for men with ADL, and 11.7 years for women vs. 6.3 years for men with IADL). After controlling for socioeconomic characteristics, chronic conditions and lifestyle factors, gender differences in ADL disability were not statistically significant. However, older women were 58% more likely (OR=1.58, 95% CI 1.27, 1.95) to report having IADL limitations than men, even after including control variables. Interventions should tackle chronic disease, physical inactivity, and socioeconomic differences to reduce women's vulnerability to disability in older age. Copyright © 2015 Elsevier Ireland Ltd.

Strontium isotope data for recent andesites in Ecuador and North Chile

International Nuclear Information System (INIS)

Francis, P.W.; Thorpe, R.S.; Moorbath, S.

1977-01-01

New Sr isotope data are presented for andesite lavas from active volcanoes in Ecuador and North Chile. Twenty-three samples from five Ecuadorian volcanoes have 87 Sr/ 86 Sr ratios most of which are essentially within analytical error, and average 0.7044. In contrast, 16 samples from the San Pedro-San Pablo volcano complex in North Chile have 87 Sr/ 86 Sr ratios between 0.7058 and 0.7072. These samples show no correlation between 87 Sr/ 86 Sr and 87 Rb/ 86 Sr, nor between 87 Sr/ 86 Sr and other elements or ratios. The major difference in setting between the two volcanic provinces lies in the thickness of the continental crust; 40-50 km beneath Ecuador, 70 km beneath North Chile. Andesites from both areas are derived primarily from the mantle, but those from North Chile show evidence of a significant Sr isotopic contribution from the continental crust. (Auth.)

Hospital malnutrition is a global health problem affecting 30-50% of hospitalized patients. There are no estimates of the size of this problem in Ecuadorian hospitals. Hospital malnutrition might influence the quality of medical assistance provided to hospitalized populations. To estimate the current frequency of malnutrition among patients admitted to Ecuadorian public hospitals. The Ecuadorian Hospital Malnutrition Study was conducted between November 2011 and June 2012 with 5,355 patients (Women: 37.5%; Ages ≥ 60 years: 35.1%; Length of stay ≤ 15 days: 91.2%) admitted to 36 public hospitals located in the prominent cities of 22 out of the 24 provinces of the country. Malnutrition frequency was estimated by means of the Subjective Global Assessment survey. Malnutrition affected 37.1% of the surveyed patients. Malnutrition was dependent upon patient's age and education level; as well as the presence of cancer, sepsis, and chronic organic failure. Hospital areas showed different frequencies of hospital malnutrition. Health condition leading to hospital admission influenced negatively upon nutritional status. Malnutrition frequency increased as length of stay prolonged. Malnutrition currently affects an important proportion of patients hospitalized in public health institutions of Ecuador. Policies and actions are urgently required in order to successfully deal with this health problem and thus to ameliorate its negative impact upon quality of medical care.

What Population Reveals about Individual Cell Identity: Single-Cell Parameter Estimation of Models of Gene Expression in Yeast.

Directory of Open Access Journals (Sweden)

Artémis Llamosi

2016-02-01

Full Text Available Significant cell-to-cell heterogeneity is ubiquitously observed in isogenic cell populations. Consequently, parameters of models of intracellular processes, usually fitted to population-averaged data, should rather be fitted to individual cells to obtain a population of models of similar but non-identical individuals. Here, we propose a quantitative modeling framework that attributes specific parameter values to single cells for a standard model of gene expression. We combine high quality single-cell measurements of the response of yeast cells to repeated hyperosmotic shocks and state-of-the-art statistical inference approaches for mixed-effects models to infer multidimensional parameter distributions describing the population, and then derive specific parameters for individual cells. The analysis of single-cell parameters shows that single-cell identity (e.g. gene expression dynamics, cell size, growth rate, mother-daughter relationships is, at least partially, captured by the parameter values of gene expression models (e.g. rates of transcription, translation and degradation. Our approach shows how to use the rich information contained into longitudinal single-cell data to infer parameters that can faithfully represent single-cell identity.

Mucopolysaccharidosis type I (MPSI) is a rare autosomal recessive disorder caused by mutations in the gene encoding the lysosomal enzyme α-l-iduronidase (IDUA), which is instrumental in the hydrolysis of the glycosaminoglycans, dermatan and heparan sulfate. The accumulation of unhydrolyzed glycosaminoglycans leads to pathogenesis in multiple tissue types, especially those of skeletal, nervous, respiratory, cardiovascular, and gastrointestinal origin. Although molecular diagnostic tools for MPSI have been available since the identification and characterization of the IDUA gene in 1992, Colombia, Ecuador, and Peru have lacked such methodologies. Therefore, the mutational profile of the IDUA gene in these countries has largely been unknown. The goal of this study was to characterize genotypes in 14 patients with MPSI from Colombia, Ecuador, and Peru. The most common mutation found at a frequency of 42.8% was W402X. Six patients presented with seven novel mutations, a high novel mutational rate in this population (32%). These novel mutations were validated using bioinformatic techniques. A model of the IDUA protein resulting from three of the novel missense mutations (Y625C, P385L, R621L) revealed that these mutations alter accessible surface area values, thereby reducing the accessibility of the enzyme to its substrates. This is the first characterization of the mutational profile of the IDUA gene in patients with MPSI in Colombia, Ecuador, and Peru. The findings contribute to our understanding of IDUA gene expression and IDUA enzyme function, and may help facilitate early and improved diagnosis and management for patients with MPSI.

Report on the oil and gas sector in Ecuador

International Nuclear Information System (INIS)

1990-01-01

After a brief introduction on the economic and political situation in Ecuador, the state of the country's oil and gas sector is reviewed. Before 1967, all oil came from wells along the Pacific coast, but with discoveries in the Amazon Basin, the opening of the trans-Ecuador pipeline, and creation of the state oil company CEPE (renamed Petroecuador in 1990) by the early 1970s, a boom in the industry occurred. Current proven reserves stand at 1.2-1.5 billion bbl of oil and 140 billion ft 3 of natural gas. Current production is generally around 300,000 bbl/d, mostly from the Petroecuador-Texaco consortium block in the Amazon Basin. Petroecuador now operates the main oil export pipeline and has subsidiaries responsible for exploration and production, refining, and the marketing of petroleum and its derivatives. In recent years Petroecuador has imported about $60 million worth of goods annually, offering a market opportunity for foreign companies supplying goods and services to the oil and gas industry. Market opportunities of interest to Canadian companies are outlined, local procedures for doing business are presented, and lists of Canadian and Ecuadorian contacts are provided. 3 figs., 5 tabs

Natural infection of sand flies with Leishmania parasites was surveyed in an Amazonian area in Ecuador where leishmaniasis is endemic. Seventy-one female sand flies were dissected and one was positive for Leishmania protozoa. The species of this sand fly was identified as Lutzomyia (Lu.) tortura on the basis of morphologic characteristics. Analysis of the cytochrome b gene sequence identified the parasite as L. (Viannia) naiffi. We report the distribution of L. (V.) naiffi in Ecuador and detection of a naturally infected sand fly in the Ecuadorian Amazon and natural infection of Lu. tortura with Leishmania parasites in the New World.

There is a reemergence of syphilis in the Latin American and Caribbean region. There is also very little information about HIV/Syphilis co-infection and its determinants. The aim of this study is to investigate knowledge, attitudes, and practices regarding sexually transmitted infections (STIs), in particular syphilis infection and HIV/Syphilis co-infection, as well as to estimate the prevalence of syphilis among men who have sex with men (MSM) in a city with one of the highest HIV prevalence rates in Ecuador. In this study, questionnaires were administered to 291 adult MSM. Questions included knowledge about STIs and their sexual practices. Blood samples were taken from participants to estimate the prevalence of syphilis and HIV/syphilis co-infection. In this population, the prevalence of HIV/syphilis co-infection was 4.8%, while the prevalence of syphilis as mono-infection was 6.5%. Participants who had syphilis mono-infection and HIV/syphilis co-infection were older. Men who had multiple partners and those who were forced to have sex had increased odds of syphilis and HIV/syphilis co-infection. A high prevalence of syphilis and self-reported STI was observed, which warrants targeted behavioral interventions. Co-infections are a cause for concern when treating a secondary infection in a person who is immunocompromised. These data suggest that specific knowledge, attitudes, and behaviors among MSM are associated with increased odds of STIs (including HIV/syphilis co-infections) in this region of Ecuador.

In recent years, the country has migratory behavior of changing migratory characteristics, ranging from the gender composition, which is now more equitable, to changes in the regions of origin and destination of migrants. Thus, in the last decade the largest migration flows come from the high-productive provinces of Pichincha and Guayas, and the main destination is Spain. While the main benefit that generates phenomena of this nature is the remittance to the mother countries, its effect has not exceeded the purely economic level. In Ecuador it has achieved better results in the balance of payments, and also an increase in the consumerist levels of people, but it has also meant greater reliance of the regions from this type of income, which has stuck the autochthon productive development of the region. Additionally, the effects of variables of great importance for the socioeconomic development of nations, such as education, have not been more encouraging. The province of Canar is one of the Ecuadorian provinces to have the higher immigration history apart the highest rate of migrants over the total population, and the flow of remittances they generate represents about 70% of non-oil gross value added.

The wide and rapid spread of Chikungunya (CHIKV) and Zika (ZIKV) viruses represent a global public health problem, especially for tropical and subtropical environments. The early detection of CHIKV and ZIKV in mosquitoes may help to understand the dynamics of the diseases in high-risk areas, and to design data based epidemiological surveillance to activate the preparedness and response of the public health system and vector control programs. This study was done to detect ZIKV and CHIKV viruses in naturally infected fed female Aedes aegypti (L.) mosquitoes from active epidemic urban areas in Ecuador. Pools (n=193; 22 pools) and individuals (n=22) of field collected Ae. aegypti mosquitoes from high-risk arboviruses infection sites in Ecuador were analyzed for the presence of CHIKV and ZIKV using RT-PCR. Phylogenetic analysis demonstrated that both ZIKV and CHIKV viruses circulating in Ecuador correspond to the Asian lineages. Minimum infection rate (MIR) of CHIKV for Esmeraldas city was 2.3% and the maximum likelihood estimation (MLE) was 3.3%. The minimum infection rate (MIR) of ZIKV for Portoviejo city was 5.3% and for Manta city was 2.1%. Maximum likelihood estimation (MLE) for Portoviejo city was 6.9% and 2.6% for Manta city. Detection of arboviruses and infection rates in the arthropod vectors may help to predict an outbreak and serve as a warning tool in surveillance programs. Copyright © 2017 Elsevier B.V.

The city of Quito (3M inhabitants), capital of Ecuador has been damaged several times in the past by large earthquakes. It is built on the hanging-wall of an active reverse fault, constituting a piggy-back basin. The deep structure of this basin and its seismic response remains badly known. We first use the recordings of 170 events on 18 accelerometers from the Quito permanent network and perform spectral ratio analysis. We find that the southern part of Quito shows strong site amplification at low frequency ( 0.35 Hz). Yet, high frequency ( 5 Hz) amplifications also exist, but exhibit a complex spatial variability. We then propose a new calibrated method based on empirical Green's functions (EGF) to simulate the ground motions due to a future earthquake in Quito. The idea is to use the results of a global database of source time functions (i.e., the SCARDEC database, Vallée and Douet, 2016; Courboulex et al., 2016) to define the average values and the variability of the stress-drop ratio parameter, which strongly affects the resulting simulations. We test the method on a Mw 7.8 event, similar in location and focal mechanism to the Pedernales earthquake that occurred on April 16th 2016 on the subduction zone. For this aim, we use the recordings of 6 aftershocks of magnitude 5.6 to 6.2 as EGF's. The predicted Fourier spectra, peak values and response spectra we obtain are in good agreement with real data from the 2016 event recorded on the Quito network. With the constraints we impose on stress-drop ratios, we expect that the simulated ground motions be representative of the variability of other Pedernales-type events that could occur in the future. Our results also well reproduce the low frequency site effects amplification in the south of the basin. This amplification could be particularly dangerous in the case of a mega subduction earthquake, like the one that struck Ecuador in 1906.

Palm oil industry in Ecuador. Good business for small farmers?

Directory of Open Access Journals (Sweden)

Lesley P. Potter

2013-10-01

Full Text Available Ecuador is the second largest producer in Latin America of crude palm oil and is the seventh largest producer worldwide, but with yields per hectare still lower than Colombia and Costa Rica. Although producers with over 1 000 hectares have the leadership in the palm oil industry, 87% of producers produce with less than 50 hectares. Moreover, the deforestation rate in Ecuador is ranked by FAO as the ninth highest in the world and the highest in South America. The African palm plantations have been criticized for causing deforestation and worsening work conditions. However, government sectors see the oil palm companies as a source of employment and development for poor regions. This fieldwork shows that there is a difference in perception among small farmers. Farmers from Quinindé-La Concordia were satisfied with the income they earn and the rising prices of land planted with palm. Farmers in San Lorenzo, in contrast, are not happy since the survey shows that a disease devastated trees and as a result, land prices have fallen in San Lorenzo.

Political Ecologies of Global Health: Pesticide Exposure in Southwestern Ecuador's Banana Industry.

Science.gov (United States)

Brisbois, Ben Wesley; Harris, Leila; Spiegel, Jerry M

2018-01-01

Pesticide exposure in Ecuador's banana industry reflects political economic and ecological processes that interact across scales to affect human health. We use this case study to illustrate opportunities for applying political ecology of health scholarship in the burgeoning field of global health. Drawing on an historical literature review and ethnographic data collected in Ecuador's El Oro province, we present three main areas where a political ecological approach can enrich global health scholarship: perceptive characterization of multi-scalar and ecologically entangled pathways to health outcomes; critical analysis of discursive dynamics such as competing scalar narratives; and appreciation of the environment-linked subjectivities and emotions of people experiencing globalized health impacts. Rapprochement between these fields may also provide political ecologists with access to valuable empirical data on health outcomes, venues for engaged scholarship, and opportunities to synthesize numerous insightful case studies and discern broader patterns.

To estimate the reference intervals for commonly used blood haematology and biochemical parameters in an adult (18-55yrs) population of residents of Mampong Akuapem. This was a population based cross sectional study of a randomly selected sample of the adult population of Mampong. The sample was selected from an updated census list of the Mampong area. Median values (95% range) for measured parameters were established as follows: Haemoglobin, (males) 14.2 g/dl (females) 12.0 g/dl Alanine aminotransferase (ALT), (female) 19.6 U/L (males) 26.1 U/L and Creatinine, (males) 108 mmol/L (females) 93 mmol/L. In comparison to reference values that are commonly used in Ghana, the haemoglobulin levels from this study were lower, and liver function parameters higher. This could be a result of genetic or environmental differences and calls for the need to establish site specific reference values applicable to our population.

Telemedicine is becoming increasingly important in Ecuador, especially in areas such as rural primary healthcare and medical education. Rural telemedicine programs in the country need to be strengthened by means of a technological platform adapted to local surroundings and offering advantages such as access to specialized care, continuing education, and so on, combined with modest investment requirements. This present article presents the design of a Telemedicine Platform (TMP) for rural healthcare services in Ecuador and a preliminary technical validation with medical students and teachers. An initial field study was designed to capture the requirements of the TMP. In a second phase, the TMP was validated in an academic environment along three consecutive academic courses. Assessment was by means of user polls and analyzing user interactions as registered automatically by the platform. The TMP was developed using Web-based technology and open code software. One hundred twenty-four students and 6 specialized faculty members participated in the study, conducting a total of 262 teleconsultations of clinical cases and 226 responses, respectively. The validation results show that the TMP is a useful communication tool for the documentation and discussion of clinical cases. Moreover, its usage may be recommended as a teaching methodology, to strengthen the skills of medical undergraduates. The results indicate that implementing the system in rural healthcare services in Ecuador would be feasible.

2013-01-01

The present study based on a nationally representative sample of older adults living in the Andes mountains and coastal region of the country indicates that 34.7% of older adults had fallen in the previous year in Ecuador. Among fallers, 30.6% reported a fall-related injury. The prevalence of falls was higher in women and among older adults residing in the rural Andes mountains. In the multivariate model, women, subjects with cognitive impairment, those reporting urinary incontinence, and those being physically active during the previous year were variables found independently associated with increased risk of falling among older adults in Ecuador. Moreover, a gradual and linear increase in the prevalence of falls was seen as the number of risk factors increased. Falls represent a major public health problem among older adults in Ecuador. The present findings may assist public health authorities to implement programs of awareness and fall prevention among older adults at higher risk of falls.

Establishment of the Eastern Cordillera of Ecuador as an Andean topographic barrier caused significant drainage reorganization, perhaps even as dramatic as the reversal of the Amazon River. Cenozoic growth of this barrier coincided with substantial increases in speciation rates in Andean and Amazonian environments. Situated in the Interandean Depression between the Eastern Cordillera and Western Cordillera of Ecuador, a series of well-preserved Miocene intermontane basins offer a unique opportunity to constrain the along-strike development of the flanking north-trending cordilleras as drainage divides in the Northern Andes. Here were provide detrital zircon U-Pb geochronological results for 17 samples from Ecuadorian hinterland basins (Cuenca, Giron-Santa Isabel, Nabón, Loja, and Vilcabamba), supplemented with measured sections in the Cuenca Basin, to provide insights on orogenic development of the cordilleras of Ecuador during the Miocene. In addition, we characterize the age distributions of basement units to more precisely determine sediment routing patterns through time. Detrital zircon geochronological data yields regional upsection trends throughout Miocene stratigraphic sections marked by: (1) middle Miocene deposits containing a strong syndepositional age peak, with a complementary Eocene-Oligocene peak in varying abundances, and subsidiary low-intensity Paleozoic-Proterozoic age peaks; and (2a) upper Miocene deposits maintaining similar trends to that of the middle Miocene, or (2b) upper Miocene deposits showing a dramatic shutoff of most Cenozoic populations and a switch to Paleozoic-Proterozoic sources, as seen in the Nabón and Loja basins. Syndepositional signatures reflect derivation from the magmatic arc, while varying inputs of Eocene-Oligocene zircons were derived from the Eocene-Oligocene volcanic rocks that comprise the effective basement of much of the Interandean Depression. The late Miocene shift to Paleozoic-Proterozoic sources observed in

To explore knowledge, beliefs, perceptions, and attitudes about tuberculosis (TB) in a high-risk group in Ecuador. This included signs and symptoms, causation, transmission, treatment, treatment adherence, impact on lifestyle and role functioning, and stigma. A convenience sample of 212 adults undergoing diagnostic TB testing at a public health facility in Quito, Ecuador, was recruited for the study. Data were collected from subjects during face-to-face interviews using a structured instrument containing closed and openended questions. Descriptive and bivariate statistics were used for quantitative analyses; content analysis was used to analyze qualitative data. Most subjects were familiar with TB and some of its characteristics and treatment aspects. However, many also held misconceptions or lacked key knowledge which could adversely affect early diagnosis and treatment and adherence to treatment, and thereby allow the disease to spread. Subject education was the single most important predictor of knowledge, beliefs, perceptions, and attitudes followed by gender, age, and prior disease experience. The subjects linked TB to multiple adverse health, economic, psychological, and social consequences, including stigma. Although none knew if they had TB when interviewed, many reported feeling stigmatized just by being tested. The subjects identified a strong need for formal educational opportunities to learn about TB prevention and control but had little access to these. The study findings highlight a need for enhanced population access to TB education. Health education and social marketing directed toward increasing TB knowledge and changing perceptions and attitudes could ultimately contribute to improved early diagnosis, treatment adherence, prevention, and decreased stigma. This could be accomplished providing that the public health infrastructure is adequate to meet demands.

Deforestation and Forest Fragmentation in South Ecuador since the 1970s - Losing a Hotspot of Biodiversity.

Deforestation and fragmentation are major components of global change; both are contributing to the rapid loss of tropical forest area with important implications for ecosystem functioning and biodiversity conservation. The forests of South Ecuador are a biological 'hotspot' due to their high diversity and endemism levels. We examined the deforestation and fragmentation patterns in this area of high conservation value using aerial photographs and Aster satellite scenes. The registered annual deforestation rates of 0.75% (1976-1989) and 2.86% (1989-2008) for two consecutive survey periods, the decreasing mean patch size and the increasing isolation of the forest fragments show that the area is under severe threat. Approximately 46% of South Ecuador's original forest cover had been converted by 2008 into pastures and other anthropogenic land cover types. We found that deforestation is more intense at lower elevations (premontane evergreen forest and shrubland) and that the deforestation front currently moves in upslope direction. Improved awareness of the spatial extent, dynamics and patterns of deforestation and forest fragmentation is urgently needed in biologically diverse areas like South Ecuador.

We performed a cross-sectional study of Trypanosoma cruzi seroprevalence in 14 communities in three provinces of Ecuador and estimated the magnitude of the association of seropositive individuals within households. A total of 3,286 subjects from 997 households were included. Seroprevalence was 5.7%, 1.0%, and 3.6% in subjects in the Manabí, Guayas, and Loja provinces, respectively. Seroprevalence increased with increasing age in Manabí and Guayas, whereas in Loja, the highest prevalence occurred in children Loja, the odds of seropositivity were more than two times greater for an individual living in a household with another seropositive person. Our results indicate that transmission of T. cruzi is ongoing in Ecuador, although intensity of transmission and mechanisms of interaction between humans and the insect vectors of disease vary between geographic regions.

The people of Tumaco-La Tolita culture inhabited the borders of present-day Colombia and Ecuador. Already extinct by the time of the Spaniards arrival, they left a huge collection of pottery artifacts depicting everyday life; among these, disease representations were frequently crafted. In this article, we present the results of the personal examination of the largest collections of Tumaco-La Tolita pottery in Colombia and Ecuador; cases of Down syndrome, achondroplasia, mucopolysaccharidosis I H, mucopolysaccharidosis IV, a tumor of the face and a benign tumor in an old woman were found. We believe these to be among the earliest artistic representations of disease.

The ELAN Ecuadorian Study of Hospital Malnutrition returned a malnutrition rate of 37.1% in public hospitals of Ecuador [Gallegos Espinosa S, Nicolalde Cifuentes M, Santana Porbén S; para el Grupo Ecuatoriano de Estudio de la Desnutrición Hospitalaria. State of malnutrition in hospitals of Ecuador. Nutr Hosp (España) 2014;30:425-35]. Hospital malnutrition could be the result of institutional cultural practices affecting the patient's nutritional status. To present the current state of food and nutritional care provided to patients assisted in public hospitals of Ecuador. The state of food and nutritional care provided to 5,355 patients assisted in 36 hospitals of 23 provinces of the country was documented by means of the Hospital Nutrition Survey (HNS), conducted as part of the ELAN Study. HNS recorded the completion of nutritional assessment exercises, the use of food-bymouth, fasting, use of oral nutritional supplements, and implementation and conduction of Artificial nutritional schemes (Enteral/Parenteral); respectively. Less than 0.1% of clinical charts had a diagnosis of malnutrition included in the list of the patient's health problems. Less than half of the patients had been measured and weighted on admission. Serum Albumin values and Total Lymphocytes Counts were annotated on admission in only 13.5% and 59.2% of the instances, respectively. Current weight value was registered in only 59.4% of the patients with length of stay ³ 15 days. An oral nutritional supplement was prescribed in just 3.5% of non-malnourished patients in which significant metabolic stress and/or reduced food intakes concurred. Although up to 10 different indications for use of Artificial nutrition were identified in the sample study, any of these techniques was administered to just 2.5% (median of observed percentages; range: 1.3 - 11.9%) of surveyed patients. Currently, nutritional status of hospitalized patient is not included within therapeutic goals, nutritional assessment

The aim of the study was to elucidate the association between the zoonotic pathogen Salmonella and a population of land iguana, Colonophus subcristatus, endemic to Galápagos Islands in Ecuador. We assessed the presence of Salmonella subspecies and serovars and estimated the prevalence of the pathogen in that population. Additionally, we investigated the genetic relatedness among isolates and serovars utilising pulsed field gel electrophoresis (PFGE) on XbaI-digested DNA and determined the antimicrobial susceptibility to a panel of antimicrobials. The study was carried out by sampling cloacal swabs from animals (n = 63) in their natural environment on in the island of Santa Cruz. A high prevalence (62/63, 98.4%) was observed with heterogeneity of Salmonella subspecies and serovars, all known to be associated with reptiles and with reptile-associated salomonellosis in humans. Serotyping revealed 14 different serovars among four Salmonella enterica subspecies: S. enterica subsp. enterica (n = 48), S. enterica subsp. salamae (n = 2), S. enterica subsp. diarizonae (n = 1), and S. enterica subsp. houtenae (n = 7). Four serovars were predominant: S. Poona (n = 18), S. Pomona (n = 10), S. Abaetetuba (n = 8), and S. Newport (n = 5). The S. Poona isolates revealed nine unique XbaI PFGE patterns, with 15 isolates showing a similarity of 70%. Nine S. Pomona isolates had a similarity of 84%. One main cluster with seven (88%) indistinguishable isolates of S. Abaetetuba was observed. All the Salmonella isolates were pan-susceptible to antimicrobials representative of the most relevant therapeutic classes. The high prevalence and absence of clinical signs suggest a natural interaction of the different Salmonella serovars with the host species. The interaction may have been established before any possible exposure of the iguanas and the biocenosis to direct or indirect environmental factors influenced by the use of antimicrobials in agriculture

34 strains of aerobic chemoorganotrophic microorganisms were isolated from 23 soil and plant samples selected from highland biotopes of Ecuador-Andes massif (Papallacta, 4020 m), ash at the foot of the volcano Tungurahua, mountainous jungle (La Favorita, 1600 m), as well as in humid tropic botanical garden (state Puyo, 950 m). In mountain jungle samples the high number of bacteria--10(5)-10(7) CFU/g of sample were represented by 2-5 morphotypes. In highland (4020 m) samples the bacterial counts made from 10(2) to 10(7) CFU/g of sample. The current study describes resistance of isolated strains to high salinity, UV radiation and toxic metal ions. The majority of isolated strains were halotolerant. Isolates from volcanic ash showed high resistance level to UV radiation--LD99,99 made 1000-1440 J/m2; resistance level for isolates from the soil of Puyo Botanical Garden and isolates from rock lichen (Papallacta) LD99,99 made 1160 and 800 J/m2 respectively. Strains isolated from mountain jungle (La Favorita) showed lower UV-resistance. In highland biotopes of Ecuador occurred bacteria resistant to toxic metal ions. The highest resistance to Hg2+ was shown by isolate of lichen from mountain jungle, the maximal growth concentration was 0.025 g/L; to Cr(VI)--by isolate from lichen rock massif--3,0 g/L. Correlation between metal-resistance, halotolerace and UV resistance for studied strains was not detected, probably because of different microbial cell damage/repair mechanisms under the action of these factors.

The Waved Albatross (Phoebastria irrorata) is a critically endangered seabird in a rapidly shrinking population in the Galápagos Islands, Ecuador. The introduction of novel pathogens and parasites poses a threat to population persistence. Monitoring disease prevalence and guarding against the spread of such agents in endemic taxa are conservation priorities for the Galápagos, where recent increases in the prevalence of avian pox may have contributed to population declines and range contractions in other bird species. During November 2013-January 2014, we identified 14 Waved Albatross nestlings at our study site on Española Island with avian pox-like lesions and clinical signs. Other seabirds, landbirds, and adult Waved Albatrosses were apparently unaffected. Histopathology of tissue samples from five infected nestlings revealed inclusion bodies in all samples, consistent with avipoxvirus infection. We documented higher mortality (6 of 14 nestlings) in affected nestlings than in unaffected young in this small outbreak of avian pox, the first report of its kind in the world's only tropical albatross.

Studies investigating a possible correlation between metabolic syndrome and cognitive decline have been inconsistent. To determine whether metabolic syndrome or each of its components correlate with cognitive performance in community-dwelling older adults in rural Ecuador. Stroke-free Atahualpa residents aged ≥60 years were identified during a door-to-door survey. Metabolic syndrome was defined according to the International Diabetes Federation criteria. Cognition was evaluated by the use of the Montreal Cognitive Assessment (MoCA). Multivariate logistic regression models estimated the association between metabolic syndrome and each of its components with cognitive performance. A total of 212 persons (mean age: 69.2 ± 7.2 years, 64 % women) were enrolled. Of these, 120 (57 %) had metabolic syndrome. Mean scores in the MoCA were 18.2 ± 4.6 for persons with and 19 ± 4.7 for those without metabolic syndrome. In fully adjusted logistic models, MoCA scores were not associated with metabolic syndrome (p = 0.101). After testing individual components of metabolic syndrome with the MoCA score, we found that only hypertriglyceridemia was independently associated with the MoCA score (p = 0.009). This population-based study showed a poor correlation of metabolic syndrome with cognitive performance after adjusting for relevant confounders. Of the individual components of metabolic syndrome, only hypertriglyceridemia correlated with worse cognitive performance.

Ecuador is well known for its extensive extant biodiversity, however, its paleobiodiversity is still poorly explored. Here we report seven new Mesozoic and Cenozoic fossil localities from the Pacific coast, inter-Andean depression and Napo basin of Ecuador, including vertebrates, invertebrates, plants, and microfossils. The first of these localities is called El Refugio, located near the small town of Chota, Imbabura Province, from where we report several morphotypes of fossil leaves and a mycetopodid freshwater mussel of the Upper Miocene Chota Formation. A second site is also located near the town of Chota, corresponding to potentially Pleistocene to Holocene lake deposits from which we report the occurrence of leaves and fossil diatoms. A third locality is at the Pacific coast of the country, near Rocafuerte, a town in Esmeraldas Province, from which we report a late Miocene palm leaf. We also report the first partially articulated skull with teeth from a Miocene scombridid (Mackerels) fish from El Cruce locality, and completely preserved seeds from La Pila locality, both sites from Manabí Province. Two late Cretaceous fossil sites from the Napo Province, one near Puerto Napo showing a good record of fossil shrimps and a second near the town of Loreto shows the occurrence of granular amber and small gymnosperms seeds and cuticles. All these new sites and fossils show the high potential of the sedimentary sequences and basins of Ecuador for paleontological studies and for a better understanding of the fossil record of the country and northern South America.

Epidemiology of Chagas disease in Ecuador. A brief review

Full Text Available Chagas disease is a complex public health problem that has been underestimated in Ecuador. Here we review the relevant published information, and present unpublished and new data that help to understand the current Chagas disease epidemiological situation and its evolution in the country. Three main characteristics have been identified: (i persistence of Trypanosoma cruzi transmission in already known foci; (ii a marked endemicity in some urban areas of Guayaquil; and (iii the transformation of new Amazon foci into truly endemic areas. The situation in other suspect areas remains uncertain. Five Triatominae species have been implicated in the transmission of T. cruzi to people in Ecuador (Triatoma dimidiata, Rhodnius ecuadoriensis, R. pictipes, R. robustus and Panstrongylus geniculatus, but some others may also play a role in some areas (P. rufotuberculatus, P. howardi, T. carrioni and P. chinai. Other Triatominae reported seem to have little or no epidemiological relevance (T. venosa, T. dispar, Eratyrus mucronatus, E. cuspidatus, P. lignarius and Cavernicola pilosa. High frequency of acute cases and severe chronic disease has been observed. Although cardiomyopathy is more frequent, serious digestive disease is also present. It is estimated that around 120,000-200,000 people may be infected. 2.2 to 3.8 million people are estimated to live under transmission risk conditions.

Full Text Available This study seeks to understand conservative political language in Ecuador during the last third of the 19th century as an expression of political modernity and as a discourse involving dialogue with liberal concepts. The conservative ideas of "Catholic freedom", "Catholic civilization" and "perfect society" are explored, and the reciprocal manner in which these concepts were defined relative to liberal notions is investigated. Using conceptual history, polysemantic political categories are analyzed in a context of struggle and in relation to the rise of modernity.

The effects of animal agriculture on the spread of antibiotic resistance (AR) are cross-cutting and thus require a multidisciplinary perspective. Here we use ecological, epidemiological, and ethnographic methods to examine populations of Escherichia coli circulating in the production poultry farming environment versus the domestic environment in rural Ecuador, where small-scale poultry production employing nontherapeutic antibiotics is increasingly common. We sampled 262 "production birds" (commercially raised broiler chickens and laying hens) and 455 "household birds" (raised for domestic use) and household and coop environmental samples from 17 villages between 2010 and 2013. We analyzed data on zones of inhibition from Kirby-Bauer tests, rather than established clinical breakpoints for AR, to distinguish between populations of organisms. We saw significantly higher levels of AR in bacteria from production versus household birds; resistance to either amoxicillin-clavulanate, cephalothin, cefotaxime, and gentamicin was found in 52.8% of production bird isolates and 16% of household ones. A strain jointly resistant to the 4 drugs was exclusive to a subset of isolates from production birds (7.6%) and coop surfaces (6.5%) and was associated with a particular purchase site. The prevalence of AR in production birds declined with bird age (P resistance (AR) in E. coli isolates from small-scale poultry production environments versus domestic environments in rural Ecuador, where such backyard poultry operations have become established over the past decade. Our previous research in the region suggests that introduction of AR bacteria through travel and commerce may be an important source of AR in villages of this region. This report extends the prior analysis by examining small-scale production chicken farming as a potential source of resistant strains. Our results suggest that AR strains associated with poultry production likely originate from sources outside the study

Declines in avian populations are a global concern, particularly for species that migrate between Arctic-temperate and tropical locations. Long-term population studies offer opportunities to detect and document ecological effects attributable to long-term climatic cycles such as the El Niño/Southern Oscillation (ENSO). In this study, we report possible population-level effects of such climatic cycles on shorebird species that use two non-breeding season sites in Ecuador (Santa Elena peninsula area, near La Libertad). During our 9-year study period (1991/1992-1999/2000), there was a particularly strong ENSO warm phase event during 1997/1998. Population trend data for three species of shorebird, Western Sandpipers ( Calidris mauri), Semipalmated Sandpipers ( C. pusilla), and Least Sandpipers ( C. minutilla), indicated abundances generally declined during the 1990s, but there was an increase in the proportion of first-year birds and their abundance in the years following the 1997/1998 ENSO warm phase. There was some support for variation in apparent survivorship associated with the onset of the ENSO warm phase event in our population models, based on capture-mark-recapture data. Following the 1997/1998 ENSO event onset, individuals for all three species were significantly lighter during the non-breeding season ( F1,3789 = 6.6, p = 0.01). Least-squares mean mass (controlling for size, sex and day of capture) for first-year birds dropped significantly more than for adults following ENSO (first-year mass loss = 0.69 ± 0.12 g; adult mass loss = 0.34 ± 0.11 g, F1,3789 = 5.31, p = 0.021), and least-squares mean mass dropped most during the period when sandpipers prepare for northward migration by gaining mass and moulting into breeding plumage. Least Sandpipers may have declined the most in mean mass following ENSO (0.76 ± 0.19 g), whereas Semipalmated Sandpipers were 0.52 ± 0.12 g lighter, and Western Sandpipers 0.40 ± 0.13 g lighter, but overall variation among

The implementation of language policy: The case of Ecuador

Ecuador is implementing a programme of indigenous bilingual intercultural education. Work began systematically in 1978 through a research centre of the Catholic University, and throughout the 1980s the government has become increasingly committed to the principle of indigenous education. In 1980 agreement was reached on a common alphabet for all indigenous languages. In the same year the government accepted that vernacular languages might be used for education, and the "Macac" educational model was devised by the Catholic University's research centre. By 1984 there were 300 bilingual primary schools, but the government then suspended its experiment. This was restored four years later, with the addition of secondary education and teacher training colleges. What is stressed by NGOs active in promoting indigenous education is not only its use of vernacular languages, but the need for intercultural exchange, recognizing in a modified curriculum the cultural values of the indigenous population and their socioeconomic reality. This change has not been understood by all government agencies, although a new Directorate for Bilingual Intercultural Education was established in 1988 to provide education for people of all ages in indigenous communities. The traditional Spanish-language formal education system has exercised a restricting influence on innovation, and the response of the dominant Spanish-speaking majority has generally been indifference.

Full Text Available In Ecuador, a factor of great ecological wealth is linked to its tradition in the use of fibers and other organic waste composite character as filler element, reinforcement or insulation in the field of housing construction, which carries great potential under the most viable architecture. The climate variability in Ecuador and the low purchasing power of their inhabitants forced to use local available building materials inexpensive or at no cost, in order to achieve economic and comfortable housing. That is why we have analyzed the presence of natural resources and waste biomass confronting regional building tradition, later superimpose geographically with major climatic variables affecting energy efficiency. This makes it possible to determine what, where and how to use the different biomass resources to allow a response to build that has a strong social, economic, environmental and energy argument in order to facilitate the conditions for access to economic habitat efficient, safe and dignified.

Litterfall production under pine plantations in the southern Andes region of Ecuador

Pablo Quichimbo

2016-09-01

Full Text Available Litterfall research is an interesting aspect in environmental studies due to its significance in nutrient cycling specially in regions like the Andes where the interactions between biomass production and its decomposition is poorly understood. This study is focusing in the litterfall biomass production under pine plantations in southern Ecuador. The litterfall production was studied for five months at two-week intervals in three pine forest sites located in the southern Andes region of Ecuador. Monthly litterfall production ranged between 1067-1907 kg ha-1, in comparison with other coniferous stands around the world, this study revealed a higher litterfall production for tropical areas and particularly the highest production under pine plantations in the Andes region. This high litterfall production highlights the upmost importance of this forest component as a potential nutrient reservoir involved in the global nutrient cycling under landscapes dominated by this exotic forest specie in the tropical Andes.

Insights from the transnational migration literature were drawn in order to think through the implications of an increasingly contradictory context of economic modernization and its impact upon the sense of possibilities and belonging of migrants. In-depth interviews with urban-destined migrants in Ecuador were drawn to argue that mobility produces ambivalent development subjects. This argument is developed in three sections. First, the paper centers on the epistemological and theoretical basis for the relevance of migrant narratives in extending theorizations of migration. Second, in-depth interviews with migrants to Quito are drawn to explore migrants' sense of belonging and regional affiliation, identity formation through migration, and experiences of alienation and disruption in their lives. Lastly, this paper concludes with a retheorization of the role of migration places in the migrant identity construction.

A new view for the geodynamics of Ecuador: Implication in seismogenic source definition and seismic hazard assessment

Yepes, Hugo; Audin, Laurence; Alvarado, Alexandra; Beauval, Céline; Aguilar, Jorge; Font, Yvonne; Cotton, Fabrice

2016-05-01

A new view of Ecuador's complex geodynamics has been developed in the course of modeling seismic source zones for probabilistic seismic hazard analysis. This study focuses on two aspects of the plates' interaction at a continental scale: (a) age-related differences in rheology between Farallon and Nazca plates—marked by the Grijalva rifted margin and its inland projection—as they subduct underneath central Ecuador, and (b) the rapidly changing convergence obliquity resulting from the convex shape of the South American northwestern continental margin. Both conditions satisfactorily explain several characteristics of the observed seismicity and of the interseismic coupling. Intermediate-depth seismicity reveals a severe flexure in the Farallon slab as it dips and contorts at depth, originating the El Puyo seismic cluster. The two slabs position and geometry below continental Ecuador also correlate with surface expressions observable in the local and regional geology and tectonics. The interseismic coupling is weak and shallow south of the Grijalva rifted margin and increases northward, with a heterogeneous pattern locally associated to the Carnegie ridge subduction. High convergence obliquity is responsible for the North Andean Block northeastward movement along localized fault systems. The Cosanga and Pallatanga fault segments of the North Andean Block-South American boundary concentrate most of the seismic moment release in continental Ecuador. Other inner block faults located along the western border of the inter-Andean Depression also show a high rate of moderate-size earthquake production. Finally, a total of 19 seismic source zones were modeled in accordance with the proposed geodynamic and neotectonic scheme.

This study describes the heritability of audiometric shape parameters and the familial aggregation of different types of presbycusis in a healthy, otologically screened population between 50 and 75 years old. About 342 siblings of 64 families (average family-size: 5.3) were recruited through population registries. Audiometric shape was mathematically quantified by objective parameters developed to measure size, slope, concavity, percentage of frequency-dependent and frequency-independent hearing loss and Bulge Depth. The heritability of each parameter was calculated using a variance components model. Logistic regression models were used to estimate the odds ratios (ORs). Estimates of sibling recurrence risk ratios (lambda(s)) are also provided. Heritability estimates were generally higher compared to previous studies. ORs and lambda(s) for the parameters Total Hearing Loss (size), Uniform Hearing Loss (percentage of frequency-dependent hearing loss) and Bulge Depth suggest a higher heredity for severe types of presbycusis compared to moderate or mild types. Our results suggest that the separation of the parameter 'Total Hearing Loss' into the two parameters 'Uniform Hearing Loss' and 'Non-uniform Hearing Loss' could lead to the discovery of different genetic subtypes of presbycusis. The parameter 'Bulge Depth', instead of 'Concavity', seemed to be an important parameter for classifying subjects into 'susceptible' or 'resistant' to societal or intensive environmental exposure. 2010 Elsevier B.V.

Scorpionism in Ecuador: First report of severe and fatal envenoming cases from northern Manabí by Tityus asthenes Pocock.

Science.gov (United States)

Borges, Adolfo; Morales, Melva; Loor, Wilmer; Delgado, Miguel

2015-10-01

The presence in rural areas of western Ecuador of scorpions in the genus Tityus capable of producing pediatric mortality is hereby evidenced. The medical significance of scorpions in Ecuador has been underestimated partly because of the clinically unimportant stings delivered by Centruroides margaritatus and Teuthraustes atramentarius, which have venom with low toxicity to vertebrates. Five intra-domiciliary cases of scorpion envenoming in victims aged between 1.9 and 16 years old, including one fatality, are reported from rural settings in forest areas of Chone (n = 2) and Flavio Alfaro (n = 3) counties, northern Manabí province, western Ecuador. Three cases were graded as Class II (moderate) and two in Class III (severe) envenoming. Manifestations showed characteristic autonomic nervous system hyper-stimulation and the fatality (a 1.9-year-old boy from Flavio Alfaro) was due to cardio-respiratory failure. Marked leukocytosis in four of the cases (21,800-31,800 cells/mm(3)), with notable neutrophilia (58-82%), suggests induction of a venom-mediated systemic inflammatory response-like syndrome. Specimens responsible for cases in Flavio Alfaro County, including the fatality, were classified as Tityus asthenes Pocock, accountable for severe scorpionism in Colombia. These findings demand implementation of control and therapeutic measures in affected areas in Ecuador, including evaluation of available scorpion antivenoms. Copyright © 2015 Elsevier Ltd.

Using a large-scale population-based study, we aimed to assess prevalence and patterns of presentation of neurocysticercosis (NCC) and its relationship with epilepsy in community-dwellers aged ≥20 years living in Atahualpa (rural Ecuador). In a three-phase epidemiological study, individuals with suspected seizures were identified during a door-to-door survey and an interview (phase I). Then, neurologists evaluated suspected cases and randomly selected negative persons to estimate epilepsy prevalence (phase II). In phase III, all participants were offered noncontrast computed tomography (CT) for identifying NCC cases. The independent association between NCC (exposure) and epilepsy (outcome) was assessed by the use of multivariate logistic regression models adjusted for age, sex, level of education, and alcohol intake. CT findings were subsequently compared to archived brain magnetic resonance imaging in a sizable subgroup of participants. Of 1,604 villagers aged ≥20 years, 1,462 (91%) were enrolled. Forty-one persons with epilepsy (PWE) were identified, for a crude prevalence of epilepsy of 28 per 1,000 population (95% confidence interval [CI] = 20.7-38.2). A head CT was performed in 1,228 (84%) of 1,462 participants, including 39 of 41 PWE. CT showed lesions consistent with calcified parenchymal brain cysticerci in 118 (9.6%) cases (95% CI = 8.1-11.4%). No patient had other forms of NCC. Nine of 39 PWE, as opposed to 109 of 1,189 participants without epilepsy, had NCC (23.1% vs. 9.2%, p = 0.004). This difference persisted in the adjusted logistic regression model (odds ratio = 3.04, 95% CI = 1.35-6.81, p = 0.007). This large CT-based study demonstrates that PWE had three times the odds of having NCC than those without epilepsy, providing robust epidemiological evidence favoring the relationship between NCC and epilepsy.

Dalbergaria tessmanii, a shrub of the Gesneriaceae locally abundant in the tropical forests of Ecuador, is variously ethnomedicinally employed. For example, none of several Shuar (Jívaro) herbal healers know or use it, but the one Shuar Shaman consulted extols its importance in reducing vaginal bleeding. Although Mestizo native consultants from the provincial capital of Morona-Santiago report its use in alleviating heart problems, those from Pastaza Province employ it to reduce menstrual flow. The Lowland Quechua apparently use it for this purpose as well. This plant has apparently not yet been chemically examined. Its reported use in several different cultural context suggest that it should be phytochemically investigated.

This study was designed to investigate the phthalates exposure levels in general population in Chongqing City of China, and to determine the possible associations between phthalate exposure and male reproductive function parameters. We recruited 232 general men through Chongqing Family Planning Research Institute and Reproductive Center of Chongqing. In a single spot urine sample from each man, phthalate metabolites, including mono-butyl phthalate (MBP), mono-ethyl phthalate (MEP), mono-(2-ethylhexyl) phthalate (MEHP), mono-benzyl phthalate (MBzP), phthalic acid (PA), and total PA were analyzed using solid phase extraction and coupled with high-performance liquid chromatography and detection by tandem mass spectrometry. Semen parameters were dichotomized based on World Health Organization reference values. Sperm DNA damage were analyzed using the alkaline single-cell gel electrophoresis assay. Reproductive hormones were determined in serum by the radioimmunoassay kit. We observed a weak association between urinary MBP concentration and sperm concentration in Chongqing general population. MBP levels above the median were 1.97 times (95% confidence interval [CI] 0.97-4.04) more likely to have sperm concentration below the reference value. There were no other associations between phthalate metabolites and reproductive function parameters after adjusted for potential risk factors. Our study suggested that general population in Chongqing area of China exposure to the environmental level of phthalate have weak or without adverse effects on the reproduction.

Full Text Available Two snapshot surveys to establish the diversity and ecological preferences of mosquitoes (Diptera: Culicidae in the terra firme primary rain forest surrounding the Tiputini Biodiversity Station in the UNESCO Yasuní Biosphere Reserve of eastern Amazonian Ecuador were carried out in November 1998 and May 1999. The mosquito fauna of this region is poorly known; the focus of this study was to obtain high quality link-reared specimens that could be used to unequivocally confirm species level diversity through integrated systematic study of all life stages and DNA sequences. A total of 2,284 specimens were preserved; 1,671 specimens were link-reared with associated immature exuviae, all but 108 of which are slide mounted. This study identified 68 unique taxa belonging to 17 genera and 27 subgenera. Of these, 12 are new to science and 37 comprise new country records. DNA barcodes [658-bp of the mtDNA cytochrome c oxidase ( COI I gene] are presented for 58 individuals representing 20 species and nine genera. DNA barcoding proved useful in uncovering and confirming new species and we advocate an integrated systematics approach to biodiversity studies in future. Associated bionomics of all species collected are discussed. An updated systematic checklist of the mosquitoes of Ecuador (n = 179 is presented for the first time in 60 years.

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.

The methodology is presented of a large-scale study of epilepsy carried out in a highland area in northern Ecuador, South America, covering a population of 72,121 people; The study was carried out in two phases, the first, a cross-sectional phase, consisted of a house-to-house survey of all persons in this population, screening for epileptic seizures using a specially designed questionnaire. Possible cases identified in screening were assessed in a cascade diagnostic procedure applied by general doctors and neurologists. Its objectives were: to establish a comprehensive epidemiological profile of epileptic seizures; to describe the clinical phenomenology of this condition in the community; to validate methods for diagnosis and classification of epileptic seizures by a non-specialised team; and to ascertain the community's knowledge, attitudes and practices regarding epilepsy. A sample was selected in this phase in order to study the social aspects of epilepsy in this community. The second phase, which was longitudinal, assessed the ability of non-specialist care in the treatment of epilepsy. It consisted of a prospective clinical trial of antiepileptic therapy in untreated patients using two standard anti-epileptic drugs. Patients were followed for 12 months by a multidisciplinary team consisting of a primary health worker, rural doctor, neurologist, anthropologist, and psychologist. Standardised, reproducible instruments and methods were used. This study was carried out through co-operation between the medical profession, political agencies and the pharmaceutical industry, at an international level. We consider this a model for further large-scale studies of this type.

During the past 15 years, Ecuador has become the Western Hemisphere's leading producer and exporter of shrimp. Growth has come about largely through mariculture development. About 8,000 metric tons (MT) of shrimp have been captured off the Ecuadorian coast each year since the late 1970s. Meanwhile, pond output has increased several-fold, from less than 5,000 MT in 1979 to over 100,000 MT 12 years later (Table 1). Mariculture has expanded largely at the expense of renewable natural resources. ...

Abstract. Here, we report the findings from the first 2 years (2014–2015) of an arbovirus surveillance study conducted in Machala, Ecuador, a dengue-endemic region. Patients with suspected dengue virus (DENV) infections (index cases, N = 324) were referred from five Ministry of Health clinical sites. A subset of DENV-positive index cases (N = 44) were selected, and individuals from the index household and four neighboring homes within 200 m were recruited (N = 400). Individuals who entered the study, other than the index cases, are referred to as associates. In 2014, 70.9% of index cases and 35.6% of associates had acute or recent DENV infections. In 2015, 28.3% of index cases and 12.8% of associates had acute or recent DENV infections. For every DENV infection captured by passive surveillance, we detected an additional three acute or recent DENV infections in associates. Of associates with acute DENV infections, 68% reported dengue-like symptoms, with the highest prevalence of symptomatic acute infections in children aged less than 10 years. The first chikungunya virus (CHIKV) infections were detected on epidemiological week 12 in 2015; 43.1% of index cases and 3.5% of associates had acute CHIKV infections. No Zika virus infections were detected. Phylogenetic analyses of isolates of DENV from 2014 revealed genetic relatedness and shared ancestry of DENV1, DENV2, and DENV4 genomes from Ecuador with those from Venezuela and Colombia, indicating the presence of viral flow between Ecuador and surrounding countries. Enhanced surveillance studies, such as this, provide high-resolution data on symptomatic and inapparent infections across the population. PMID:29512482

The recent scale-up in malaria control measures in Latin America has resulted in a significant decrease in the number of reported cases in several countries including Ecuador, where it presented a low malaria incidence in recent years (558 reported cases in 2015) with occasional outbreaks of both Plasmodium falciparum and Plasmodium vivax in the coastal and Amazonian regions. This success in malaria control in recent years has led Ecuador to transition its malaria policy from control to elimination. This study evaluated the general knowledge, attitude and practices (KAP) about malaria, as well as its prevalence in four communities of an endemic area in northwest Ecuador. A total of 258 interviews to assess KAP in the community indicated that most people in the study area have a basic knowledge about the disease but did not use to contribute to its control. Six hundred and forty-eight blood samples were collected and analysed by thick blood smear and real-time PCR. In addition, the distribution of the infections was mapped in the study communities. Although, no parasites were found by microscopy, by PCR the total malaria prevalence was 7.5% (6.9% P. vivax and 0.6% P. falciparum), much higher than expected and comparable to that reported in endemic areas of neighbouring countries with higher malaria transmission. Serology using ELISA and immunofluorescence indicated 27% respondents for P. vivax and 22% respondents for P. falciparum. Results suggest that despite a great malaria reduction in Ecuador, transition from control to elimination would demand further improvement in malaria diagnostics, including active case detection to identify and treat parasite asymptomatic carriers, as well as community participation in its elimination.

Full Text Available In the context of coffee growing, Ecuador is characterized by planting two main commercial species of Coffea arabica L. (Arabica coffee, and Coffea canephora Pierre ex Froehner (Robusta coffee, where small production units and agroforestry systems predominate. To overcome the low national production, which constitutes the central problem of coffee growing in the country, the Ministry of Agriculture and Livestock of Ecuador, promoted the project «Reactivation of the Ecuadorian coffee industry», which contributes to food security and nutrition with integral approach. In these circumstances, the objective of this paper is to analyze the importance of coffee agroforestry systems for agro-alimentary and nutritional security in Ecuador. The proposal is born from the agro-economic diagnosis «case study», from the situation of the Coffee Production Units, from the Association of Peasants «Juntos Lucharemos» from the La Unión parish of the Jipijapa county, province of Manabí, in which they settled Main contributions to the agro-alimentary and nutritional security coming from the coffee agroforestry systems, this allowed to analyze characteristics related to the object of study. Based on the research results, gaps in national consumption needs were detected. This proposal contributed to articulate and promote the reactivation of coffee growing on agroecological bases, in harmony with the dimensions of sustainability in order to protect and conserve biodiversity and the coffee forest.

Full Text Available Purpose. Analysis of the dynamics of structural parameters as an integral property of the processes of recruitment and elimination of the reproductive and commercial population nuclei of pikeperch of the Kyiv reservoir. Methodology. Ichthyological material was collected during spring-summer period of 2015-2016 from survey catches done with gill nets with mesh sizes of 30-120 mm. Collection and processing of the field materials were carried out using conventional methods. In total, catches of 3.5 thousand net-days were processed during the study period and 1031 individual pikeperch were analyzed. Total mortality coefficient (Z was determined by graphic method based on the dynamics of the natural logarithms of the abundances of different age groups. Statistical processing of data was done in MS Excel. Findings. Commercial landings of pikeperch during last 10 years has a clear trend for a growth: from 20-25 to 80-100 tons. The catch of pikeperch per unit effort of survey gill nets in an interannual aspect is also characterized by a growth. At the same time, there is a certain improvement of the structural parameters of pikeperch population, e.g. an increase in the maximum age and extension of the modal frequency distribution. Age-3 and age-4 fish represented the major part of the population (71.6% in the catches of 2015, while the share of age-5-6 fish was also relatively high (10.8%. It resulted in an increase in the weighed mean age of the pikeperch population to 4.5 years. For 2016, there is a significant shift of the frequency distribution to its left wing – the major part of the population (64.7% was composed of age-2 to age-4 fish. The weighed mean age in 2016 decreased to 2.6 years that was due first of all to abundant recruitment and intensive elimination of middle age groups. Total mortality (Z of pikeperch in 2015-2016 was 0.53-0.56 that corresponded to normal conditions of the formation of the commercial stock of this species and

This study provides comprehensive information on the past and current status of the Andean cutaneous leishmaniasis (Andean-CL, uta) in Peru and Ecuador, mainly focusing on the causative Leishmania parasites and clinico-epidemiological features. Available information and data including our unpublished works were analyzed thoroughly. Endemic regions of the Andean-CL (uta) in Peru run from the north Piura/Cajamarca to the south Ayacucho at a wide range of the Pacific watersheds of the Andes through several departments, while in Ecuador those exist at limited and spotted areas in the country's mid-southwestern two provinces, Azuay and Chimborazo. The principal species of the genus Leishmania are completely different at subgenus level, L. (Viannia) peruviana in Peru, and L. (Leishmania) mexicana and L. (L.) major-like (infrequent occurrence) in Ecuador. The Peruvian uta is now prevalent in different age and sex groups, being not clearly defined as found in the past. The precise reasons are not known and should be elucidated further, though probable factors, such as emergence of other Leishmania parasites, non-immune peoples' migration into the areas, etc., were discussed briefly in the text. The Andean-CL cases in Ecuador are more rural than before, probably because of a rapid development of the Leishmania-positive communities and towns, and the change of life-styles of the inhabitants, including newly constructed houses and roads in the endemic areas. Such information is helpful for future management of the disease, not only for Leishmania-endemic areas in the Andes but also for other endemic areas. Copyright © 2017 Elsevier B.V.

Full Text Available A natural disaster leading to accumulation of environmental contaminants may have substantial effects on the male reproductive system. Our aim was to compare and assess semen parameters in a normospermic population residing in the Southern Louisiana, USA area pre- and post-Hurricane Katrina. We retrospectively evaluated semen analyses data (n = 3452 of 1855 patients who attended the Tulane University Andrology/Fertility Clinic between 1999 and 2013. The study inclusion criteria were men whose semen analyses showed ≥ 1.5 ml volume; ≥15 million ml -1 sperm concentration; ≥39 million total sperm count; ≥40% motility; >30% morphology, with an abstinence interval of 2-7 days. After the inclusion criteria applied to the population, 367 normospermic patients were included in the study. Descriptive statistics and group-based analyses were performed to interpret the differences between the pre-Katrina (Group 1, 1999-2005 and the post-Katrina (Group 2, 2006-2013 populations. There were significant differences in motility, morphology, number of white blood cell, immature germ cell count, pH and presence of sperm agglutination, but surprisingly there were no significant differences in sperm count between the two populations. This long-term comparative analysis further documents that a major natural disaster with its accompanied environmental issues can influence certain semen parameters (e.g., motility and morphology and, by extension, fertility potential of the population of such areas.

A new species of the genus Centrolene (Amphibia : Anura : Centrolenidae) from Ecuador with comments on the taxonomy and biogeography of Glassfrogs

Cisneros-Heredia, D.F.; McDiarmid, R.W.

2006-01-01

We describe a new species of Glassfrog, Centrolene mariaelenae n. sp., from the Contrafuerte de Tzunantza, southeastern Ecuador. The new species is assigned to the Centrolene gorzulai species group, a clade previously known only from the Guayana Shield region, because the parietal peritoneum is transparent and the hepatic peritoneum is covered by guanophores. We analyze the diversity patterns of Glassfrogs from eastern Ecuador. The distribution of the new species herein described supports previous hypothesis of a biogeographical connection between the Andes and the Guayana Shield for various groups of plants and animals; particularly a relationship between the Guayana Shield and the sandstone outcrops mountain ranges of southeastern Ecuador and northeastern Peru. We also comment on the infrageneric and generic classification of Glassfrogs, and propose the new combinations Centrolene balionotum n. comb., Cochranella antisthenesi n. comb., and Cochranella pulverata n. comb.

Abstract The detection and identification of natural infections in sand flies by Leishmania protozoan species in endemic areas is a key factor in assessing the risk of leishmaniasis and in designing prevention and control measures for this infectious disease. In this study, we analyzed the Leishmania DNA using nuclear ribosomal internal transcript spacer (ITS) sequences. Parasite DNA was extracted from naturally infected, blood-fed sand flies collected in nine localities considered leishmaniasis-endemic foci in Ecuador. The species of parasites identified in sand flies were Leishmania major-like, Leishmania naiffi, Leishmania mexicana, Leishmania lainsoni, and “Leishmania sp. siamensis”. Sand fly specimens of Brumptomyia leopoldoi, Mycropigomyia cayennensis, Nyssomyia yuilli yuilli, Nyssomyia trapidoi, Pressatia triacantha, Pressatia dysponeta, Psychodopygus carrerai carrerai, Psychodopygus panamensis, and Trichophoromyia ubiquitalis were found positive for Leishmania parasite. These findings contribute to a better understanding of the epidemiology and transmission dynamics of the disease in high-risk areas of Ecuador. PMID:28981860

BACKGROUND Asthma has emerged as an important public health problem of urban populations in Latin America. Epidemiological data suggest that a minority of asthma cases in Latin America may be associated with allergic sensitisation and that other mechanisms causing asthma have been overlooked. The aim of the present study was to investigate risk factors for atopic and non-atopic asthma in school-age children. METHODS A cross-sectional study was conducted among 3960 children aged 6-16 years living in Afro-Ecuadorian rural communities in Esmeraldas province in Ecuador. Allergic diseases and risk factors were assessed by questionnaire and allergic sensitisation by allergen skin prick reactivity. RESULTS A total of 390 (10.5%) children had wheeze within the previous 12 months, of whom 14.4% had at least one positive skin test. The population-attributable fraction for recent wheeze associated with atopy was 2.4%. Heavy Trichuris trichiura infections were strongly inversely associated with atopic wheeze. Non-atopic wheeze was positively associated with maternal allergic symptoms and sedentarism (watching television (>3 h/day)) but inversely associated with age and birth order. CONCLUSIONS The present study showed a predominance of non-atopic compared with atopic wheeze among schoolchildren living in a poor rural region of tropical Latin America. Distinct risk factors were associated with the two wheeze phenotypes and may indicate different causal mechanisms. Future preventive strategies in such populations may need to be targeted at the causes of non-atopic wheeze.

This paper reports that there has been considerable turbulence in Ecuador's E and P sector over the last year. For instance, Energy Minister Diego Tramariz was replaced by the country's Congress after he raised subsidized fuel prices. Ecuadoran and U.S. environmentalists, meanwhile, raised a firestorm of controversy over the on-again, off- again development of Conoco's Block 16 in Yasuni National Park. Finally, Unocal and PetroCanada this spring terminated their respective drilling operations after fruitless multiwell efforts. New Energy Minister Donald Castillo certainly has his work cut out in attempting to maintain stability in upstream activity. To that end, Castillo has stated that one of his top priorities will be to maintain a good working relationship with foreign operators. He also expected a seventh round of exploratory blocks to be offered before summer's end to shore up activity. Castillo reiterated in public statements that he stands by the administration's existing energy policies, including development of Block 16

The Ecuador-Peru Peace Process

Directory of Open Access Journals (Sweden)

Marcel Fortuna Biato

Full Text Available Abstract The 1998 Brasilia Peace Agreement ended a territorial dispute between Ecuador and Peru that, due to the size and location of the contested area, had remained a source of regional instability and continental tensions for decades. This paper examines the circumstances that finally allowed negotiations, beginning in 1995, to overcome an almost two-centuries-old conflict, long after almost all territorial disputes in South America had been laid to rest. It will focus in particular on the diplomatic endeavours by the guarantor countries of the 1942 Rio de Janeiro Protocol, which involved a unique set of negotiations, and the setting up of the first effective multilateral peace operation in South America. It also suggests that the peace agreement benefited from the dynamics of economic integration underway since the 1980s. Finally, it considers the implications for regional security arrangements, as well as Brazil’s leadership credentials in South America.

The relict forests of Northwest Peru and Southwest Ecuador

Maximilian Weigend

2013-05-01

Full Text Available The forest fragments or relict forests on the Western slopes of the Andes in northwest Peru and in south-west Ecuador are fragile ecosystems, which were largely continuous at some stage in the past. The importance and uniqueness of these forests as «refuges» and stable habitats roots partly in their complex diversity and their high levels of endemicity. These in turn are the outcome of a complex topography and ecology. In this introductory chapter 12 studies are analysed, which were presented at the Taller sobre Bosques Relictos de la Vertiente Occidental Andina del Norte del Perú y Sur del Ecuador in May 2004 at the X CONABOT, Trujillo-Perú. This helps to consolidate and update our knowledge on these over 20 forests fragments in northern Peru and two previously unknown fragments are presented for the first time: Bosque La Oscurana (Cajamarca and Kañaris (Lambayeque. Some ideas are exposed on the the relationships between the relict forests, how to analyse their dynamics, how to characterize their structure and how their conservation may be achieved. It is proposed that crucial elements in a conservation of these forests are a urgently inventorizing them to demonstrate their high diversity b emphasizing their economic potential with respect to the abundance of phytogenetic ressources c evaluating their role as catchment areas for the rivers which are the primary source of water for agriculture and urban life on the coast.

Biomass burning in the Amazon-fertilizer for the mountaineous rain forest in Ecuador.

Science.gov (United States)

Fabian, Peter; Kohlpaintner, Michael; Rollenbeck, Ruetger

2005-09-01

Biomass burning is a source of carbon, sulfur and nitrogen compounds which, along with their photochemically generated reaction products, can be transported over very long distances, even traversing oceans. Chemical analyses of rain and fogwater samples collected in the mountaineous rain forest of south Ecuador show frequent episodes of high sulfate and nitrate concentration, from which annual deposition rates are derived comparable to those found in polluted central Europe. As significant anthropogenic sources are lacking at the research site it is suspected that biomass burning upwind in the Amazon basin is the major source of the enhanced sulfate and nitrate imput. Regular rain and fogwater sampling along an altitude profile between 1800 and 3185 m has been carried out in the Podocarpus National Park close to the Rio SanFrancisco (3 degrees 58'S, 79 degrees 5'W) in southern Ecuador. pH values, electrical conductivity and chemical ion composition were measured at the TUM-WZW using standard methods. Results reported cover over one year from March 2002 until May 2003. Annual deposition rates of sulfate were calculated ranging between 4 and 13 kg S/ha year, almost as high as in polluted central Europe. Nitrogen deposition via ammonia (1.5-4.4 kg N/ha year) and nitrate (0.5-0.8 kg N/ha year) was found to be lower but still much higher than to be expected in such pristine natural forest environment. By means of back trajectory analyses it can be shown that most of the enhanced sulfur and nitrogen deposition is most likely due to forest fires far upwind of the ecuadorian sampling site, showing a seasonal variation, with sources predominantly found in the East/North East during January-March (Colombia, Venezuala, Northern Brazil) and East/SouthEast during July-September (Peru, Brazil). Our results show that biomass burning in the Amazon basin is the predominant source of sulfur and nitrogen compounds that fertilize the mountaineous rain forest in south Ecuador. The

Genetic characterization of Venezuelan equine encephalitis virus from Bolivia, Ecuador and Peru: identification of a new subtype ID lineage.

Directory of Open Access Journals (Sweden)

Patricia V Aguilar

2009-09-01

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.

Full Text Available El sistema de medios públicos en Ecuador está compuesto por 22 medios de diferente origen y estructura, constituyéndose un poder nuevo y sin límites claros, que intenta competir con medios privados y tradicionales del país, cuya administración es de carácter familiar y monopólico. Los medios públicos en Ecuador distan de las características universales planteadas para este tipo de medios, básicamente por la cercanía con los organismos del Estado, en general. La competencia entre medios públicos y privados es desigual, situación que modifica la agenda mediática nacional, dejando a la luz algunas debilidades y limitaciones del ejercicio periodístico y del manejo de la empresa periodística, en particular. El presente artículo se fundamenta en un análisis descriptivo de los medios de comunicación en Ecuador y el juego de poderes que ha desatado la presencia de medios públicos en esta última década. Analizan también el rol del periodismo y su posición frente a los temas vitales para el país, evidenciando la ausencia de una política integral a favor del ciudadano y debilidades en la profesión periodística. Concluye con recomendaciones para mejorar el papel de los medios en Ecuador.

Full Text Available In the paper we analyze the inequalities that emerge from and are reproduced in Ecuadorian’s higher education trajectories in the context of economic crises. We focus on the strategies that these youth and their families employ for social mobility as well as the role of public policy in these processes. We examine the trajectories of three groups: sons and daughters of the 2000 migration wave from Ecuador to Spain who study at universities in Spain, those who have returned to Ecuador for their studies, and Ecuadorians who move to Spain in order to carry out postgraduate studies, some of them funded by scholarships from the Ecuadorian government. The research project employed a qualitative methodology based on interviews, focus groups and a survey with Ecuadorians in Spain who took the entrance exam for admittance into Ecuador’s public university system. Our findings highlight the varied forms of capitals that these diverse students employ, as well as the social and economic constraints that they encounter. In a period of economic crisis in Spain, the first group of students must often downgrade their expectations in order to continue their studies. Their experience contrasts starkly with Ecuadorians undertaking postgraduate studies in Spain, whose heterogenous trajectories are upwardly and geographically mobile. The case of the return university students to Ecuador shows us that education is inserted into a broader strategy that depends on transnational networks shaped over more than a decade of Ecuador-Spain migration.

A lo largo de los siglos, el proceso de modernización del Ecuador ha estado bajo la mira de políticos, gobernantes, maestros, pensadores e historiadores. El primer paso de esta odisea se dio a mediados del S. XVIII y se presentó como ruptura y enfrentamiento con el pasado, en diversas áreas y tuvo como trasfondos la muerte del sistema colonial y el anuncio de nuevos referentes, fuerzas, actores y formas de organizar la realidad.

Although burnout is a widespread phenomenon among healthcare professionals, there are no studies about its prevalence in Ecuador. This study assesses the prevalence of burnout syndrome among Ecuadorian healthcare professionals and examine the relationship with their personal and organizational characteristics. A total of 2404 healthcare professionals (average age 40.0years; 68.4% women) from the capitals of all 24 provinces in Ecuador participated in this study. Trained psychologists assessed the presence of burnout by applying the Maslach Burnout Inventory. Sociodemographic variables, emotional distress, social support and coping styles as well as organizational variables were also collected. Of all healthcare professionals surveyed, 2.6% presented burnout syndrome. By dimensions, 17.2% of the participants presented a high level of emotional exhaustion, 13.5% of depersonalization, and 18.2% had reduced personal accomplishment. Being non-mestizo, being classified as a probable case of mental disorder and using more passive coping were associated with a greater probability of presenting burnout; having >10years of experience was associated with a lower probability of burnout. A significant number of active health professionals suffer from burnout. It is necessary to develop effective psychotherapeutic interventions for those who have the syndrome and to evaluate potential prevention strategies in those who have not yet developed it.

Describe strategies implemented by Ecuador's Ministry of Public Health (MPH) to strengthen human resources for health leadership and respond to the new model of care, as a part of the reform process in the period 2012-2015. A documentary review was carried out of primary and secondary sources on development of human resources for health before and after the reform. In the study period, Ecuador developed a new institutional and regulatory framework for developing human resources for health to respond to the requirements of a model of care based on primary health care. The MPH consolidated its steering role by forging strategic partnerships, implementing human resources planning methods, and making an unprecedented investment in health worker training, hiring, and wage increases. These elements constitute the initial core for development of human resources for health policy and a health-services study program consistent with the reform's objectives. Within the framework of the reform carried out from 2012 to 2015, intersectoral work by the MPH has led to considerable achievements in development of human resources for health. Notable achievements include strengthening of the steering role, development and implementation of standards and regulatory instruments, creation of new professional profiles, and hiring of professionals to implement the comprehensive health care model, which helped to solve problems carried over from the years prior to the reform.

To determine that Paragonimus sp. is actively transmitted in a tropical area of the Pacific region of Ecuador where human cases of pulmonary paragonimiasis have recently been documented, a total of 75 freshwater crabs were collected from 2 different streams in the Pedernales area of Manabí Province, Ecuador. All collected crabs were identified as Hypolobocera guayaquilensis based on morphological characteristics of the male gonopods. The hepatopancreas of each crab was examined by compressing it between 2 glass plates followed by observation under a stereomicroscope. Excysted Paragonimus metacercariae were detected in 39 (52.0%) crabs and their densities varied from 1 to 32 per infected crab. There was a positive relationship between crab size and metacercarial density. Sequences of the second internal transcribed spacer region of the ribosomal RNA gene of the Paragonimus metacercariae obtained in this study were identical to those of Paragonimus mexicanus deposited in the DDBJ/EMBL/GenBank database. Thus, the present study is the first to confirm that the crab species H. guayaquilensis is the second intermediate host of P. mexicanus in Manabí Province, Ecuador. Because this crab might be the possible source of human infections in this area, residents should pay attention to improper crab-eating habits related with a neglected parasitic disease, i.e., paragonimiasis.

We report on empirical trends between the dynamically determined stellar initial mass function (IMF) and stellar population properties for a complete, volume-limited sample of 260 early-type galaxies from the ATLAS 3D project. We study trends between our dynamically derived IMF normalization α dyn ≡ (M/L) stars /(M/L) Salp and absorption line strengths, and interpret these via single stellar population-equivalent ages, abundance ratios (measured as [α/Fe]), and total metallicity, [Z/H]. We find that old and alpha-enhanced galaxies tend to have on average heavier (Salpeter-like) mass normalization of the IMF, but stellar population does not appear to be a good predictor of the IMF, with a large range of α dyn at a given population parameter. As a result, we find weak α dyn -[α/Fe] and α dyn –Age correlations and no significant α dyn –[Z/H] correlation. The observed trends appear significantly weaker than those reported in studies that measure the IMF normalization via the low-mass star demographics inferred through stellar spectral analysis

The populations were collected through two macro-sites (Central coastals: Quevedo, Ventanas, la Guayas; Andean surroundings: la Maná, Patricia Pilar, Pichincha. The populations showed the following traits: straight shaft (66%; round, irregular top shape (50%; and branch insertion angle 0° - 30° (86%. Four qualitative (straight shape, type of leaf edge, leaf width and leaf pubescence and four quantitative (commercial tree height, basal area, commercial volume and total volume traits were the most explicative traits present after Principal Component Analysis (PCA. PCA separated populations into two groups: one group included populations from Central Coastals which showed morphological traits highly and positively correlated with wood production, and the other group included populations with lower tree growth from the Andean surroundings. Populations from Central Coastals showed the highest values of genetic diversity indexes, AFLP markers separated populations based on the macro site of origin. For K = 2 Bayesian analysis separated FS populations into two groups; two populations from Central Coastals region and the other four the Andean surroundings region (3 and 1 from Central Coastals (La Guayas. For greater K values, the genetic fragmentation of populations by origins was evident since for K = 5 four groups were performed: one including populations from Quevedo and Ventanas and other from La Guayas (Coastals, the third group included trees from La Mana and Pichincha and the fourth, from Patricia Pilar (Andean surroundings. Results suggested the constant and effective genetic recombination or the genetic flow among and within Fernan Sanchez populations with a clear tendency

Full Text Available En Ecuador, el acceso de la población rural a servicios adecuados de atención secundaria de salud se ha hecho cada vez más difícil. A pesar de que los sectores público y privado han acertado en dedicar esfuerzos a la atención primaria y a la salud pública, la mayoría de las poblaciones rurales no tienen acceso a una adecuada atención secundaria. Por lo general, los modelos tradicionales de atención médica secundaria en zonas rurales no se han adaptado a las nuevas situaciones, como la tendencia general a la descentralización, el énfasis en el desarrollo de capacidades locales, el antagonismo entre el acceso universal y la autonomía financiera, las alternativas financieras innovadoras y los recién llegados médicos de familia. En 2001, la organización no gubernamental con sede en los Estados Unidos de América Andean Health & Development (Saludesa en Ecuador inauguró un hospital rural de 17 camas, construido conjuntamente con el municipio local y el Ministerio de Salud de Ecuador. El hospital atiende a una comunidad rural de 50000 personas que antes no tenían acceso local a servicios secundarios de salud. Los esfuerzos de AHD/Saludesa para desarrollar una red autosostenible pública/privada de atención primaria/secundaria de salud y de alta calidad han generado una considerable experiencia en la administración de un hospital rural. El proyecto piloto de AHD se concentró en un hospital rural y logró su autosostenibilidad total en 2007. Esto se logró mediante una combinación de mecanismos financieros, entre ellos la venta de paquetes prepagados de atención sanitaria, un contrato con el Instituto Ecuatoriano de Seguridad Social, contribuciones municipales y el pago tradicional por los servicios.

Bastidas Zelaya, E.

2016-07-01

Because of the growth of cities in size and population, people get used to perform several stage trips involving transfers due to advantages such as time or price paid, being multistage trips more attractive compared to single stage trips. In Quito, Ecuador, nowadays multistage trips represent one third of total daily trips. This paper seeks to identify main characteristics of multistage trips as well as find relationships and inferences that allow recommendations regarding best practices to policy makers and transport managers. The information used belong to the data collected in the Household Survey Mobility held in Quito in 2011. Based on these data, the present work starts using an analysis with descriptive statistics. The next phase of this research involves the search for a methodology in order to identify correlations between demographic, socioeconomic and transport variables related with traveler´s choice for making or not a transfer. Best methodology found was the use of Binary Logistic Regression (Logit) and specific computer software, with which different statistic's models were performed to find the strongest correlation. The paper ends with conclusions and recommendations as well as suggestions for future research. (Author)

Creating a Social Wasteland? Non-Traditional Agricultural Exports and Rural Poverty in Ecuador

Full Text Available Neoliberal economic policies in Latin America  have resulted in the rapid growth of nontraditional agricultural exports (NTAE. This  growth is often seen as contributing to the alleviation of rural poverty. The paper examines this  view with the focus on Ecuador, using the World  Bank’s definition poverty as a reference. It is  argued that the flower export expansion has created employment opportunities but did not allow  the rural poor to raise themselves above the poverty line. Moreover, flower employment has undermined the pre-existing social networks and community organizations, increasing the levels of insecurity among rural families and undermining  their ability to influence the processes of decision  making.  Resumen: Creando un páramo social?

En este artículo se  estudia esta visión para el caso de Ecuador, utilizando como referencia la definición de pobreza  del Banco Mundial. Aunque se dice que la expansión en la exportación de flores ha creado oportunidades de empleo, no ha logrado que los pobres  rurales crucen la línea de la pobreza. Además, el empleo en este sector ha socavado las redes sociales y organizaciones comunitarias anteriores,  elevando los niveles de inseguridad entre las  familias rurales y minando su capacidad de intervención en el proceso de toma de decisiones.

Economic reforms and change in the energy sector: the case of Ecuador

International Nuclear Information System (INIS)

Dahik, Alberto.

1993-01-01

The failure of both democracies and revolutions in Latin America is due to the fact that the State has been trusted with political, economic and social organization, instead of relying on the motivations and capabilities of intermediate associations and the individual members of society. Therefore, the process of change is not just a matter of national decision; it is something that must, and will, take place. Ecuador understands perfectly well the need for reform. Major laws have already been enacted, and a bill for modernization of the State is currently under consideration by congress. The concept of modernization and, therefore, change does not merely imply new laws, simplified procedures or easier operations; it basically means allowing the creative forces of individuals, enterprises and intermediate associations to play a more influential role. As in other Latin American countries, in Ecuador there can be no real modernization, no real change in society without a major revolution in energy and telecommunications. Thus, two important laws have been drafted to demonopolize petroleum and electric power operations and open them up both to national and foreign private sector participation

Full Text Available RESUMEN: Las élites y el sistema político ecuatoriano han, tradicionalmente marginado, la integración y la participación en el proceso de toma de decisiones de los indígenas aunque este sector de la población formara parte de la etapa fundacional de la sociedad ecuatoriana. En las tres últimas décadas la situación se ha ido transformando y, paralelamente al proceso de democratización experimentado por el sistema político en su conjunto, los indígenas han comenzado a organizarse y se han ido convirtiendo en un actor con gran capacidad de presión en la vida política del país. Este trabajo reflexiona acerca del proceso de incorporación política de los indígenas en el marco institucional del Ecuador y, en particular, analiza el período que abarca desde la utilización de "modos alternativos de acción política" hasta su integración a las instituciones a partir del empleo de los instrumentos de "participación política" del sistema político. En este marco se analiza el papel desempeñado las organizaciones indígenas como la Confederación de Nacionalidades Indígenas del Ecuador (CONAIE y por el Movimiento de Unidad Plurinacional Pachakutik-Nuevo País (MUPP-NP. La hipótesis principal de este trabajo es que el proceso de modernización rural llevado a cabo desde el Estado, la iglesia, las organizaciones no gubernamentales (ONG's y los organismos internacionales ha facilitado la incorporación del sector indígena campesino al sistema político a través del desarrollo organizativo de las comunidades.ABSTRACT: Elites and political system in Ecuador have traditionally marginalized integration and participation in process of decision-marking of indigenous people, even if this sector of population were part of the founders of ecuatorian society.

Estimating mutation parameters, population history and genealogy simultaneously from temporally spaced sequence data.

Drummond, Alexei J; Nicholls, Geoff K; Rodrigo, Allen G; Solomon, Wiremu

2002-07-01

Molecular sequences obtained at different sampling times from populations of rapidly evolving pathogens and from ancient subfossil and fossil sources are increasingly available with modern sequencing technology. Here, we present a Bayesian statistical inference approach to the joint estimation of mutation rate and population size that incorporates the uncertainty in the genealogy of such temporally spaced sequences by using Markov chain Monte Carlo (MCMC) integration. The Kingman coalescent model is used to describe the time structure of the ancestral tree. We recover information about the unknown true ancestral coalescent tree, population size, and the overall mutation rate from temporally spaced data, that is, from nucleotide sequences gathered at different times, from different individuals, in an evolving haploid population. We briefly discuss the methodological implications and show what can be inferred, in various practically relevant states of prior knowledge. We develop extensions for exponentially growing population size and joint estimation of substitution model parameters. We illustrate some of the important features of this approach on a genealogy of HIV-1 envelope (env) partial sequences.

Rural residence is protective against atopy and wheeze-rhinitis-eczema symptoms in developed countries, an effect attributed to farming and poor hygiene exposures. There are few data from developing countries addressing this question. We compared atopy and wheeze-rhinitis-eczema symptoms between urban and rural Ecuador, and explored the effects of farming and poor hygiene exposures. We performed cross sectional studies of schoolchildren living in rural and urban Ecuador. Data on symptoms and farming/hygiene exposures were collected by parental questionnaire, atopy by allergen skin prick test reactivity and geohelminth infections by stool examinations. Among 2526 urban and 4295 rural schoolchildren, prevalence was: atopy (10.0% vs 12.5%, p=0.06), wheeze (9.4% vs 10.1%, p=0.05), rhinitis (8.1% vs 6.4%, p=0.02) and eczema (5.9% vs 4.7%, p=0.06). A small proportion of symptoms were attributable to atopy (range 3.9-10.7%) with greater attributable fractions for respiratory symptoms observed in urban schoolchildren. Respiratory symptoms were associated with poor hygiene/farming exposures: wheeze with lack of access to potable water; and rhinitis with household pets, no bathroom facilities and contact with large farm animals. Birth order was inversely associated with respiratory symptoms. Area of residence and atopy had few effects on these associations. Urban schoolchildren living in Ecuador have a similar prevalence of atopy, eczema and wheeze but a higher prevalence of rhinitis compared with rural children. Some farming and poor hygiene exposures were associated with an increase in the prevalence of wheeze or rhinitis while birth order was inversely associated with these symptoms.

Background Rural residence is protective against atopy and wheeze–rhinitis–eczema symptoms in developed countries, an effect attributed to farming and poor hygiene exposures. There are few data from developing countries addressing this question. We compared atopy and wheeze–rhinitis–eczema symptoms between urban and rural Ecuador, and explored the effects of farming and poor hygiene exposures. Methods We performed cross sectional studies of schoolchildren living in rural and urban Ecuador. Data on symptoms and farming/hygiene exposures were collected by parental questionnaire, atopy by allergen skin prick test reactivity and geohelminth infections by stool examinations. Results Among 2526 urban and 4295 rural schoolchildren, prevalence was: atopy (10.0% vs 12.5%, p=0.06), wheeze (9.4% vs 10.1%, p=0.05), rhinitis (8.1% vs 6.4%, p=0.02) and eczema (5.9% vs 4.7%, p=0.06). A small proportion of symptoms were attributable to atopy (range 3.9–10.7%) with greater attributable fractions for respiratory symptoms observed in urban schoolchildren. Respiratory symptoms were associated with poor hygiene/farming exposures: wheeze with lack of access to potable water; and rhinitis with household pets, no bathroom facilities and contact with large farm animals. Birth order was inversely associated with respiratory symptoms. Area of residence and atopy had few effects on these associations. Conclusions Urban schoolchildren living in Ecuador have a similar prevalence of atopy, eczema and wheeze but a higher prevalence of rhinitis compared with rural children. Some farming and poor hygiene exposures were associated with an increase in the prevalence of wheeze or rhinitis while birth order was inversely associated with these symptoms. PMID:24105783

The objective of this study was to determine the presence of the variants of canine parvovirus (CPV)-2 in the city of Quito, Ecuador, due to the high domestic and street-type canine population, and to identify possible mutations at a genetic level that could be causing structural changes in the virus with a consequent influence on the immune response of the hosts. Thirty-five stool samples from different puppies with characteristic signs of the disease and positives for CPV through immunochromatography kits were collected from different veterinarian clinics of the city. Polymerase chain reaction and DNA sequencing were used to determine the mutations in residue 426 of the VP2 gene, which determines the variants of CPV-2; in addition, four samples were chosen for complete sequencing of the VP2 gene to identify all possible mutations in the circulating strains in this region of the country. The results revealed the presence of the three variants of CPV-2 with a prevalence of 57.1% (20/35) for CPV-2a, 8.5% (3/35) for CPV-2b, and 34.3% (12/35) for CPV-2c. In addition, complete sequencing of the VP2 gene showed amino acid substitutions in residues 87, 101, 139, 219, 297, 300, 305, 322, 324, 375, 386, 426, 440, and 514 of the three Ecuadorian variants when compared with the original CPV-2 sequence. This study describes the detection of CPV variants in the city of Quito, Ecuador. Variants of CPV-2 (2a, 2b, and 2c) have been reported in South America, and there are cases in Ecuador where CVP-2 is affecting even vaccinated puppies.

A countrywide epidemiological study was performed to elucidate the current geographic distribution of causative species of cutaneous leishmaniasis (CL) in Ecuador by using FTA card-spotted samples and smear slides as DNA sources. Putative Leishmania in 165 samples collected from patients with CL in 16 provinces of Ecuador were examined at the species level based on the cytochrome b gene sequence analysis. Of these, 125 samples were successfully identified as Leishmania (Viannia) guyanensis, L. (V.) braziliensis, L. (V.) naiffi, L. (V.) lainsoni, and L. (Leishmania) mexicana. Two dominant species, L. (V.) guyanensis and L. (V.) braziliensis, were widely distributed in Pacific coast subtropical and Amazonian tropical areas, respectively. Recently reported L. (V.) naiffi and L. (V.) lainsoni were identified in Amazonian areas, and L. (L.) mexicana was identified in an Andean highland area. Importantly, the present study demonstrated that cases of L. (V.) braziliensis infection are increasing in Pacific coast areas.

, erythromycin, norfloxacin, ciprofloxacin, gentamycin, chloramphenicol, and colistin. Results. In 1998 there were 3 755 cases reported in 17 of the 21 provinces of the country. This corresponds to an incidence rate of 53.96 per 100 000 population. Thirty-seven patients died, for a case fatality rate of 0.97%. A total of 301 strains of V. cholerae were isolated in the 637 suspected-cholera samples that were processed; all corresponded to V. cholerae O1, El Tor, subtype Ogawa. All of the strains were sensitive to tetracycline and to quinolones; 5.6% of the strains were resistant to erythromycin. The only strain resistant to amoxicillin was multiresistant. Officials in Ecuador implemented a series of preventive measures, and the surveillance system was strengthened in order to reduce the impact of the disease. Conclusions. The preventive measures helped to reduce the impact of the 1998 cholera epidemic in Ecuador, in terms of both incidence and the case fatality rate. Given the overall sensitivity of the strains to the antimicrobial drugs, there is no reason to change the current treatment regimens in the country. Taking into account the frequency of natural disasters in Ecuador and the relation that they have to the reappearance of cholera, interventions should be designed that make it possible to prevent and control the reappearance of the disease and its spread to the most vulnerable provinces of the central Sierra mountainous region and the eastern part of the country.

Full Text Available We studied the behavior of campaign hashtags on Twitter in the second round of Ecuador 2017 presidential elections. The study analyzed 10 trending hashtags attacking opponents. The data was captured and analyzed with NodeXL, an application used to analyze social network. The analysis verifies the central role of automated accounts or botnets in the creation of hashtags. The campaign against the opposing binomial, which combined real accounts of government party activists with botnets, was more effective versus the less coordinated opposition campaign against candidate Lenin Moreno. It also verifies the use of localized botnets, mainly in Argentina and Venezuela.

Fission track dating was applied in order to study obsidian samples originated from Mullumica and Callejones flows, Oyacachi, Ecuador. Preliminary data show that the ratio between the mean diameter os spontaneous and induced tracks is about 0.9, an indication that the analysed samples were submitted to small fading during their geological histories. Ages were obtained around 0.2 x 10 6 a, in agreement with Miller and Wagners's results. Ages ranging from 0.17 x 10 6 a up to 0.23 x 10 6 a were obtained correcting the apparent ages by means of the plateau method. (author)

Critical Phenomena of Rainfall in Ecuador

Serrano, Sh.; Vasquez, N.; Jacome, P.; Basile, L.

2014-02-01

Self-organized criticality (SOC) is characterized by a power law behavior over complex systems like earthquakes and avalanches. We study rainfall using data of one day, 3 hours and 10 min temporal resolution from INAMHI (Instituto Nacional de Meteorologia e Hidrologia) station at Izobamba, DMQ (Metropolitan District of Quito), satellite data over Ecuador from Tropical Rainfall Measure Mission (TRMM,) and REMMAQ (Red Metropolitana de Monitoreo Atmosferico de Quito) meteorological stations over, respectively. Our results show a power law behavior of the number of rain events versus mm of rainfall measured for the high resolution case (10 min), and as the resolution decreases this behavior gets lost. This statistical property is the fingerprint of a self-organized critical process (Peter and Christensen, 2002) and may serve as a benchmark for models of precipitation based in phase transitions between water vapor and precipitation (Peter and Neeling, 2006).

Fasciolosis is a widely distributed disease in livestock in South America but knowledge about the epidemiology and the intermediate hosts is relatively scarce in Ecuador. For three months, lymnaeid snails were sampled (n = 1482) in Pichincha Province at two sites located in a highly endemic area. Snails were identified (based on morphology and ITS-2 sequences) and the infection status was established through microscopic dissection and a multiplex polymerase chain reaction (PCR)-based technique. Techniques based on morphology were not useful to accurately name the collected snail species. Comparison with available DNA sequences showed that a single snail species was collected, Galba schirazensis. Live rediae were observed in 1.75% (26/1482) and Fasciola sp. DNA was detected in 6% (89/1482) of collected snails. The COX-1 region permitted identification of the parasite as Fasciola hepatica. The relative sensitivity and specificity of the microscope study, compared to PCR results, were 25.84% and 99.78%, respectively. The mean size of the snails recorded positive for F. hepatica through crushing and microscopy was significantly higher than the mean size of negative snails, but there was no such difference in PCR-positive snails. The role of G. schirazensis as an intermediate host of F. hepatica in Ecuador is discussed and the hypothesis of an adaptation of the parasite to this invasive snail is proposed. For the first time, an epidemiological survey based on molecular biology-based techniques assessed the possible role of lymnaeid snails in the epidemiology of fasciolosis in Ecuador. © Y.

Lessmann, Janeth; Muñoz, Jesús; Bonaccorso, Elisa

2014-01-01

Ecuador has the largest number of species by area worldwide, but also a low representation of species within its protected areas. Here, we applied systematic conservation planning to identify potential areas for conservation in continental Ecuador, with the aim of increasing the representation of terrestrial species diversity in the protected area network. We selected 809 terrestrial species (amphibians, birds, mammals, and plants), for which distributions were estimated via species distribution models (SDMs), using Maxent. For each species we established conservation goals based on conservation priorities, and estimated new potential protected areas using Marxan conservation planning software. For each selected area, we determined their conservation priority and feasibility of establishment, two important aspects in the decision-making processes. We found that according to our conservation goals, the current protected area network contains large conservation gaps. Potential areas for conservation almost double the surface area of currently protected areas. Most of the newly proposed areas are located in the Coast, a region with large conservation gaps and irreversible changes in land use. The most feasible areas for conservation were found in the Amazon and Andes regions, which encompass more undisturbed habitats, and already harbor most of the current reserves. Our study allows defining a viable strategy for preserving Ecuador's biodiversity, by combining SDMs, GIS-based decision-support software, and priority and feasibility assessments of the selected areas. This approach is useful for complementing protected area networks in countries with great biodiversity, insufficient biological information, and limited resources for conservation. PMID:25360277

Full Text Available The Intercultural Bilingual Education System in Ecuador is guaranteed by the Constitution and assured by the Organic Law of Intercultural Bilingual Education, in a process that took a few decades to the indigenous population. The Ecuadorian state currently counts with a Model of Intercultural Bilingual Education that has its own structure, attached to the Ministry of Education and responsible for generating educational guidelines for 35 indigenous nationalities that coexist in the country. The objective of this study is to analyze the social demand for the Bachelor in Intercultural Bilingual Education, offered by Universidad Politécnica Salesiana. The analysis was carried out through two studies, one of them quantitative, addressed to educational institutions, and the other one qualitative and directed to government officials. The research objectives were to determine the need for graduates in Intercultural Bilingual Education, identify the desired profile of graduates of the career and academic requirements for a successful career. The results highlighted that the current presence of professionals in bilingual intercultural education is 0,65 per institution, with an average necessity of 1,85, which determines the existence of a demand in the next three years of 3 315 professionals. The main conclusion is that there is a significant demand for this career. Although the deficiencies of the current educational system, there in a strengthening trend.

Full Text Available OBJECTIVE: To identify and describe the sociodemographic and nutritional characteristics associated with neurobehavioral development among young children living in three communities in the northeastern Andean region of Cayambe-Tabacundo, Ecuador. METHODS: Women in the study communities who had a child 3 to 61 months of age completed a questionnaire about maternal and child health and sociodemographic characteristics. The Ages and Stages Questionnaire (ASQ was directly administered to 283 children by two trained interviewers. Growth measurements and a hemoglobin finger-prick blood test were obtained in 2003-2004. Prevalence of developmental delay was calculated, and associations between child development and maternal, child, and household characteristics were explored. RESULTS: High frequencies of developmental delay were observed. Children 3 to 23 months old displayed delay in gross motor skills (30.1%, and children 48 to 61 months old displayed delay in problem-solving skills (73.4% and fine motor skills (28.1%. A high frequency of both anemia (60.4% and stunting (53.4% was observed for all age groups. Maternal educational level was positively associated with communication and problem-solving skills, and monthly household income was positively associated with communication, gross motor, and problem-solving skills. CONCLUSIONS: The results suggest a high prevalence of developmental delay and poor child health in this population. Child health status and the child's environment may contribute to developmental delay in this region of Ecuador, but sociodemographic factors affecting opportunities for stimulation may also play a role. Research is needed to identify what is causing high percentages of neurobehavioral developmental delay in this region of Ecuador.OBJETIVOS: Identificar y describir las características sociodemográficas y nutricionales asociadas con el desarrollo neuroconductual en niños pequeños de tres comunidades de la regi

We report on empirical trends between the dynamically determined stellar initial mass function (IMF) and stellar population properties for a complete, volume-limited sample of 260 early-type galaxies from the ATLAS{sup 3D} project. We study trends between our dynamically derived IMF normalization α{sub dyn} ≡ (M/L){sub stars}/(M/L){sub Salp} and absorption line strengths, and interpret these via single stellar population-equivalent ages, abundance ratios (measured as [α/Fe]), and total metallicity, [Z/H]. We find that old and alpha-enhanced galaxies tend to have on average heavier (Salpeter-like) mass normalization of the IMF, but stellar population does not appear to be a good predictor of the IMF, with a large range of α{sub dyn} at a given population parameter. As a result, we find weak α{sub dyn}-[α/Fe] and α{sub dyn} –Age correlations and no significant α{sub dyn} –[Z/H] correlation. The observed trends appear significantly weaker than those reported in studies that measure the IMF normalization via the low-mass star demographics inferred through stellar spectral analysis.

Full Text Available The study presents the population indices of the life quality of inhabitants of Dakhadaev district, Republic of Dagestan. The study was conducted using a questionnaire SF-36. The regularities of the age-and gender changes of parameters of the life quality were identified. The highest rate in the analyzed settlements was marked on a scale of social functioning, the lowest – on the scale of overall health. The integral indexes of men were higher in all age groups than those of women. The highest parameters of the integral index of the male and female population were fixed in the age-group to 35. The most gender differences are noted on the scale of the role-physical functioning, the least on the scale of social functioning. In whole with age increasing we saw lowering parameters of indices of the life quality as in male group, so in female one. Besides the most changes in indices of the life quality were on the scale of role-physical functioning. Minimal differences in age groups were observed on the scales of social functioning and mental health. Women have more age lowering of indices of the life quality than men exceptthe role-physical functioning and social functioning. The highest parameter of the integral index of the life quality was observed in Zilbachi administrative settlement, the lowest one – in Kharbuk settlement of Dakhadaev district, Republic of Dagestan. The data of population study of the life quality give the information about indices of the life quality of population, reflecting in such a way the degree of its physical, psychological and social wellbeing.

REDD+ and the Indigenous Question: A Case Study from Ecuador

Directory of Open Access Journals (Sweden)

Pablo Reed

2011-04-01

Full Text Available One of the main issues regarding the implementation of REDD+ in Latin America has been the growing concern that such projects may infringe upon the rights and negatively affect the livelihoods of forest-dependent communities. Various indigenous and civil society organizations are ardently opposed to the initiative. Such is the case in Ecuador, where indigenous opposition to REDD+ represents a considerable obstacle in the creation of a national strategy since more than 60% of the country’s remaining forest cover is on indigenous land or under indigenous occupation. Thus one of the most critical challenges remaining for Ecuador will be the construction of a strong legal, financial, and institutional framework—one that the greater indigenous community might be willing to accept. Closer examination of this topic however, reveals just how difficult this may become. Lack of information, a recent political split between national authorities and the indigenous sector, and the dissimilar organizational capacity levels of indigenous communities make the feasibility of carrying out REDD+ projects on these lands extremely complex. However, the biggest obstacle may be ideological. Many indigenous groups view REDD+, with its possible emphasis on international markets and neoliberal mechanisms, as a continuation of the type of policies that have impeded their quest for sovereignty and self determination. As such, indigenous people are only willing to consider such projects if they clearly see preconditions in place that would safeguard their cultures, territories, and autonomy.

Full Text Available OBJECTIVE: To explore knowledge, beliefs, perceptions, and attitudes about tuberculosis (TB in a high-risk group in Ecuador. This included signs and symptoms, causation, transmission, treatment, treatment adherence, impact on lifestyle and role functioning, and stigma. METHODS: A convenience sample of 212 adults undergoing diagnostic TB testing at a public health facility in Quito, Ecuador, was recruited for the study. Data were collected from subjects during face-to-face interviews using a structured instrument containing closed and open-ended questions. Descriptive and bivariate statistics were used for quantitative analyses; content analysis was used to analyze qualitative data. RESULTS: Most subjects were familiar with TB and some of its characteristics and treatment aspects. However, many also held misconceptions or lacked key knowledge which could adversely affect early diagnosis and treatment and adherence to treatment, and thereby allow the disease to spread. Subject education was the single most important predictor of knowledge, beliefs, perceptions, and attitudes followed by gender, age, and prior disease experience. The subjects linked TB to multiple adverse health, economic, psychological, and social consequences, including stigma. Although none knew if they had TB when interviewed, many reported feeling stigmatized just by being tested. The subjects identified a strong need for formal educational opportunities to learn about TB prevention and control but had little access to these. CONCLUSIONS: The study findings highlight a need for enhanced population access to TB education. Health education and social marketing directed toward increasing TB knowledge and changing perceptions and attitudes could ultimately contribute to improved early diagnosis, treatment adherence, prevention, and decreased stigma. This could be accomplished providing that the public health infrastructure is adequate to meet demands.OBJETIVO: Explorar los

Up to this date, there are no reports made about the use of media for recruiting research volunteers in Latin American populations. Given the emergence of clinical research in Ecuador, a study of this kind in the local population will be beneficial for future research, and is probably applicable to other countries in the region. Two public calls were made for a cross-sectional study on cognitive function and diabetes. We only included people between 55 and 65 years of age without previous neurocognitive conditions. We invited individuals through interviews on the radio, television broadcasts and local newspapers, along with social media ads. Each individual was asked about the method by which they learned of the project. We calculated the frequency in which each method was reported and a chi-square test was used to assess gender differences in the results. A total of 274 patients were enrolled in the study, 64.2% are women and 35.8% men. We found that 29.93% learned of it from third persons, 20.8% through radio, 8.76% through social media, 8.39% by newspaper, and 5.11% by television, while a remaining 27.01% had not previously heard of the recruitment call. Methods reported varied significantly between men and women (p = 0.03). Traditional media were the most common method of recruitment, with radio interviews being the most frequently reported. Individually, none of them surpassed the frequency of people learning of the project from other people (snowball effect). Social networks play an important role, exceeding certain traditional media. We have described for the first time in Latin America the use of media as methods to recruit volunteers for research, and the importance of project dissemination by the participants to reach more people.

The widespread of Fe(III)-reducing microorganisms in natural ecosystems of Ecuador of La Favorita, Tungurahua volcano and Papallacta areas was experimentally proved. High efficiency of microbial precipitation of soluble iron compounds was also demonstrated. Obtained results indicate the potential ability of Fe(III)-reducing microorganisms to influence the formation of carbon and iron vector fluxes in ecosystems, as well as development of effective biotechnologies of water purification from iron compounds.

Bali cattle (Bos javanicus) is Indonesian indigenous cattle with having superior genetics potential on fitness traits in tropical environment and low feed quality. Bali Cattle Breeding Center Pulukan Indonesia conducted progeny test per annum in order to select bulls using offspring’s phenotype. This paper aimed to estimate the genetic parameters of yearling weight in Bali cattle progeny test populations and to observe the variation between periods in the above breeding center. Data were collected from the year of 2013 to 2014. There were four bulls (3 tests, 1 AI control) in 2013 and five bulls (4 tests, 1 AI) in 2014. Thirty breeding females were allocated per paddock per bull and allowed to mate naturally. In total 80 and 104 offspring’s records were obtained from 2013 and 2014 data, respectively. We built half-sib family model to estimate the additive genetic variance due to the sire and later estimate the breeding value (EBV) of each sire. Results showed that in 2013 the heritability (h2) for yearling weight was 0.19 while in 2014 was 0.79. In both years, tested bulls had higher EBV compared to the control bulls. The remarkable difference of heritability between years was due to the variations among bull candidates which might differ every year with regards to their origins. The fact that the EBV of tested bulls were higher than the control bulls gave us insight that despite the conservation policy and the continuous departure of Bali cattle bulls outside the Island, the population could still maintain its genetic quality.

Cutaneous leishmaniasis is a neglected tropical disease transmitted by phlebotomine sand flies of the genus Lutzomyia. In South America, cutaneous leishmaniasis is endemic in the majority of countries. There are no previous reports of phlebotomine sand fly host feeding sources in Ecuador. We identified blood meal sources for phlebotomine sand fly species in Valle Hermoso, a hyper endemic area for leishmaniasis in Ecuador. Phlebotomine sand fly collections were carried out during the dry and rainy seasons. PCR and multiplex PCR were performed from DNA extracted from the abdomens of blood-fed females to specifically identify the avian and mammalian blood meal sources. Avian-blood (77%), mammalian-blood (16%) and mixed avian-mammalian blood (7%) were found in the samples. At the species level, blood from chickens (35.5%), humans (2.8%), cows (2.8%) and dogs (1.9%) was specifically detected. Nyssomyia trapidoi was the most common species of Lutzomyia found that fed on birds. The present results may aid the development of effective strategies to control leishmaniasis in Ecuador.
