    Full Text Available Over a two year period, the incidence of hepatitis C virus (HCV infection was evaluated in 29 hemodialysis patients, aged between 15 and 75 years (mean ± SD: 45 ± 39.5 years, from the University Hospital Hemodyalisis Unit, Maracaibo, Zulia State, Venezuela. Anti-HCV antibodies were determined using a fourth generation ELISA (Innotest HCV Ab IV kit and positive blood samples were tested using a recombinant assay kit (Inno-LIA HCV Ab III, both kits from Innogenetics N.V., Belgium. The findings indicate a lack of HCV seroconversion in the hemodialysis patients over the study period, confirmed by the recombinant assay. Risk factors for HCV infection were 0.3270 (95% confidence interval: 0.01323-8.080 in patients undergoing hemodialysis. The findings suggest a lack of significant sources for HCV infection due to the preventive measures to avoid its transmission in the hemodialysis unit.

  6. La producción informal de viviendas: caso Maracaibo, Venezuela

    Oteiza San José, Ignacio

    1989-10-01

    Full Text Available In housing production in Venezuela and particularly in Maracaibo, we can recognize two main sectors: the "formal" sector production carried out by private and national enterprises, and the "informal" sector, which produces houses in marginal areas and uncontrolled suburbs in town. The production in this sector has become larger than the formal one. In act, in Maracaibo more than 60% of population is living in these types of suburbs. These people have resolved their housing need accordingly to their low income and outside of offer sector of formal production. This paper analyses the house from a physical point of view by studying the constructives components in relation to the socioeconomical aspects of the families and their direct participation in building and financing their house. Four stages of the physical consolidation of housing in suburbs were distinguish. This contribution as an analytic description of the physical situation of housing in studied areas, concluded giving some recommendations for the improvement of the informal process of housing production in Maracaibo.

    En la producción de viviendas en Maracaibo (Venezuela existen dos sectores: el SECTOR FORMAL se refiere a la producción de la empresa privada más la producción estatal y el SECTOR INFORMAL que es la producción de viviendas en las áreas de barrios; la producción de este sector es mayor que la formal, llegando a ser el 60% de la población de Maracaibo. En Latinoamérica este fenómeno se presenta en la mayoría de las grandes ciudades. Este trabajo analiza la vivienda desde el punto de vista físico, relacionando los aspectos constructivos con los socioeconómicos, de participación en la construcción y del financiamiento. Se establecieron 4 etapas de consolidación de la vivienda de producción informal, caracterizando cada una de las etapas de acuerdo a los promedios y porcentajes obtenidos.

  7. The Cogollo Group and the oceanic anoxic events 1a and 1b, Maracaibo basin, Venezuela

    José Alejandro Méndez Dot

    Full Text Available ABSTRACTCarbonates of Cogollo Group (Apón, Lisure and Maraca formations constitute the broader calcareous platform system originated during Aptian and Albian of Cretaceous in north-western South America, Maracaibo Basin, Venezuela. On the shallow shelf, a variety of calcareous sedimentary facies were deposited during marine transgressive and regressive cycles. Some of them developed porosity and constitute important hydrocarbon reservoirs. Due to some major marine transgressions, from early Aptian, the anoxic environment and characteristic facies of a pelagic environment moved from the outer slope and basin to the shallow shelf, during specific time intervals, favouring the sedimentation of organic matter-rich facies, which correspond to the oceanic anoxic events (OAEs 1a and 1b. The source rock of Machiques Member (Apón Formation was deposited during early Aptian OAE 1a (~ 120 Ma. The source rock of Piché Member, located at the top of the Apón Formation, was deposited during late Aptian OAE 1b (~ 113 Ma. Finally, La Luna Formation, from Cenomanian, that covers the OAE 2 (~ 93 Ma, represents the most important source rock in the Maracaibo Basin. In this way and based on sedimentological and organic geochemistry results from the determinations performed on 247 samples belonging to six cores in the Maracaibo Basin, we propose these two organic-rich levels, deposited on the shallow shelf of the Cogollo Group, as "effective source rocks", additional to La Luna Formation, with oil migration in relatively small distances to the porosity facies.

  8. Environmental planning related to the oil industry activities at Maracaibo Lake Venezuela

    German, F.

    1993-01-01

    Maracaibo Lake has been the center of most of the hydrocarbon exploration and production activities in Venezuela since the early twenties, with a total cumulative oil extraction of nearly 40 billion barrels. The intensive activities related to production have brought a wide variety of ecosystem perturbations, as a consequence of the construction of facilities for exploration, transport, treatment, storage, and oil refining, as well as the generation of effluents, emissions, and solid wastes therein associated. The Venezuelan Petroleum Corporation (PDVSA) has recognized the importance of preventing further potential damage from its current operations and future expansions, with an additional concern for restoring affected areas. Herein, actual and future restoration/mitigation environmental planning will be discussed, emphasizing a research program focused on the Maracaibo Lake region, being conducted by PDVSA's R ampersand D Corporative branch. Research main objective is to gather, for PDVSA operating companies, a priority setting, as a function of environmental or ecological risks, related to the oil industry activities. To this end, efforts will be directed from a multidisciplinary approach, taking into account some of the major links structuring ecosystem complexity

  9. Prevalence and Associated Factors of Insulin Resistance in Adults from Maracaibo City, Venezuela

    Valmore Bermudez

    2016-01-01

    Full Text Available Background and Aim. Insulin resistance (IR is a prominent pathophysiologic component in a myriad of metabolic disorders, including obesity, prediabetes, and type 2 diabetes mellitus, which are common in our locality. The objective of this study was to determine the prevalence of IR and factors associated with this condition in an adult population from Maracaibo city, Venezuela. Methodology. A cross-sectional, descriptive study with multistaged randomized sampling was carried out in 2026 adults. IR was defined as HOMA2-IR ≥ 2. A multiple logistic regression model was constructed in order to evaluate factors associated with IR. Results. The prevalence of IR was 46.5% (n=943, with 46.7% (n=450 in the general population, 46.4% (n=493 in females, and 47.90% (n=970 in males (p=0.895. IR prevalence tended to increase with age and was significantly greater in subjects aged ≥30 years (χ2=16.726; p=2.33×10-4. Employment, alcohol consumption, obesity, high triacylglycerides, low HDL-C, and dysglycemia were associated with greater odds of IR, whereas a high level of physical activity appeared to be weak protective factor against IR. Conclusions. The prevalence of IR is elevated in our locality. The main determinants of this condition appear to be the presence of obesity, high triacylglycerides, low HDL-C, dysglycemia, and alcohol intake.

  10. Household energy use in urban Venezuela: Implications from surveys in Maracaibo, Valencia, Merida, and Barcelona-Puerto La Cruz

    Figueroa, M.J.; Sathaye, J.

    1993-08-01

    This report identifies the most important results of a comparative analysis of household commercial energy use in Venezuelan urban cities. The use of modern fuels is widespread among all cities. Cooking consumes the largest share of urban household energy use. The survey documents no use of biomass and a negligible use of kerosene for cooking. LPG, natural gas, and kerosene are the main fuels available. LPG is the fuel choice of low-income households in all cities except Maracaibo, where 40% of all households use natural gas. Electricity consumption in Venezuela`s urban households is remarkably high compared with the levels used in households in comparable Latin American countries and in households of industrialized nations which confront harsher climatic conditions and, therefore, use electricity for water and space heating. The penetration of appliances in Venezuela`s urban households is very high. The appliances available on the market are inefficient, and there are inefficient patterns of energy use among the population. Climate conditions and the urban built form all play important roles in determining the high level of energy consumption in Venezuelan urban households. It is important to acknowledge the opportunities for introducing energy efficiency and conservation in Venezuela`s residential sector, particularly given current economic and financial constraints, which may hamper the future provision of energy services.

  11. Las ciudades disidentes durante la independencia de Venezuela: el caso de Maracaibo

    Zulimar Maldonado Viloria

    2005-01-01

    Full Text Available En este estudio de caso se analizan las particularidades del proceso histórico que vivió Maracaibo durante los primeros años de la Independencia Venezolana. Es de interés para la historiografía venezolana y latinoamericana profundizar en el análisis de la realidad que explica la reacción de una “ciudad disidente” como Maracaibo, cuya elite prefirió seguir los lineamientos de la Regencia, elegir su diputado para las Cortes de Cádiz y defender su autonomía, antes que aceptar la propuesta de emancipación caraqueña. Bajo esta perspectiva se pretende esclarecer si la elite maracaibera fue realmente “disidente” del movimiento caraqueño por inercia histórica, larga herencia hispánica, o su actuación estuvo apegada a la legitimidad del momento como una opción política para lograr reafirmar y acrecentar su autonomía dentro del régimen monárquico. La investigación se ubica en la actual corriente historiográfica europea e hispanoamericana que sale al paso a los tradicionales análisis sustentados en una visión fáctica y localista, ignorando la amplitud temporal y espacial del proceso; se centra en el conocimiento que aporta el estudio comparado de la actitud de Maracaibo ante la Independencia con su desarrollo en el resto del país y acontecimientos en el mundo hispánico.

    Incidence of anencephaly in the State of Zulia, and specifically in the Eastern Coast of Lake Maracaibo, an oil exploitation area, has been declared high since the beginning of the 80's, coincident with the generalized use of ultrasound as a diagnostic tool for fetal evaluation. Through the Birth Defects Preventive Program, established at the Hospital Chiquinquira in Maracaibo, we have developed a fourfold strategy for the study of birth defects: i) analysis of more than 32,332 ultrasound evaluations within the Ultrasound Service, between 1993 and 1996, ii) a case-control malformation registry beginning in 1995, iii) a study of malformed stillbirths at the Pathology Service, observed after 4232 deliveries within this hospital, and iv) a registry of over 638 mothers with high risk pregnancy for fetal defects detected at the prenatal clinic and carried out at the Perinatal Medical Genetics Service. As a reference population we study 345 medical histories obtained from the Medical Genetics and Prenatal Diagnostic Service at Hospital Coromoto, and oil companies related medical facility. This approach has led us to conclude that the incidence of anencephaly in the State of Zulia is 0.75/1000, significantly similar to that expected for most populations

    To detect the presence of microsporidia and other enteric parasites in patients with HIVAIDS of the Autonomous Services University Hospital of Maracaibo (SAHUM), where there are no previous studies in this field. Fecal samples were analyzed by means of direct exam, concetration method with formal-ether, Kinyoun coloration and fast Gram-Chromotrope coloration. Separate PCR were perfomed to differentiate Entamoeba histolytica and Entamoeba dispar , when the E. histolytica/E. dispar complex was observed in the microscope. Information on the patient was obtained trough clinical history. Of 56 individuals that participated, 38 (67.86%) presented some commensal parasite and/ or pathogenic species in their fecal sample. Carriers of pathogenic species were predominat (26/38). Protozoa such as Isospora belli protozoa (17.65%), Blastocystis spp. (17.65%), Cryptosporidium spp. (7.84%), E. histolytica/E. dispar (5.88%), Entamoeba coli (3.92%), Giardia lamblia (3.92%), Endolimax nana (3.92%), Cyclospora cayetanensis (3.92%), and Chilomastix mesnilli (1.96%) were diagnosed. Among the helminths, Ascaris lumbricoides, Trichuris trichiura and Strongyloides stercoralis , had a percentage of 27.27% each, and Hymenolepis nana , 18.18%. Entamoeba histolytica was only detected in one of three cases presenting complex microscopic examination. By Gram-chromotrope, 17 samples showed spores of the Microsporidia phylum, equivalent to 33.33% prevalence. Microsporidia may be first prevalente in HIV positive patients when specific diagnostic techniques are used.

  15. Geochemical and geological control on filling history of Eocene reservoirs, Maracaibo Basin, Venezuela

    Alberdi, M.; Maguregui, J.; Toro, C.; Marquina, M. [Intevep S.A., Caracas (Venezuela)

    1996-08-01

    Crude oils of Eocene fluvio-deltaic reservoirs in {open_quotes}Bloque V{close_quotes} and {open_quotes}Centro Lago{close_quotes} fields in the center of the Maracaibo Lake show many differences in composition, which are due to stratigraphically and structurally controlled reservoir geometry and a low rate of in-reservoir mixing of at least two successive petroleum charges. Oils produced from the top of structural highs contain 18(H) oleanane, higher Pr/Ph and C{sub 23-3}/C{sub 24-4} ratios, a lower proportion of DBT/P compounds, and clearly different fingerprint patterns in the C{sub 6}-C{sub 15} range, than those observed in oils produced from the lower parts of the structures. These compositional differences suggest that two source rocks, or two distinctive organic facies within the same Cretaceous La Luna Formation, generated and filled vertically poorly connected Eocene reservoirs. On the other hand, saturate-biomarkers ratios, triaromatics (C{sub 21}/C{sub 21}+C{sub 28}), n-paraffins (n-C{sub 20}/n-C{sub 29}) and n-heptane index suggest that oils in upper reservoirs are slightly less mature than oils in lower reservoirs and, consequently filled the structure first. Additional evidence from formation water analysis and tectonic basin evolution allow us to interpret at least two petroleum pulses from Cretaceous source rocks during Upper Miocene to present day kitchens located in the Andes foredeep at the southeast of the study area.

    Full Text Available El objetivo de la investigación fue evaluar el efecto de diferentes tratamientos pregerminativos, así como las características morfológicas de las plántulas emergidas en cuatro leguminosas forrajeras arbóreas: lara ruidosa (Albizia lebbeck, cují (Prosopis juliflora, samán (Samanea saman y carocaro (Enterolobium cyclocarpum, presentes en la altiplanicie de Maracaibo, estado Zulia, Venezuela. El diseño experimental fue de bloques al azar, con cuatro repeticiones. Los tratamientos aplicados fueron: escarificación con lija (EL, remojo en agua (RA e inmersión en agua caliente (IAC, en semillas con distintos tiempos de almacenamiento (TA. Se evaluó el porcentaje de emergencia (PE, la tasa de emergencia (TE, la altura de la plántula (AP, el largo de la raíz (LR, el número de hojas (NH, el número de nudos (NN y el grosor del tallo (GT. En lara ruidosa el tiempo del RA y la interacción entre la EL y la IAC presentaron diferencias significativas en el PE. En las semillas de cují, los efectos individuales del TA, el RA y la IAC mostraron diferencias en el PE. La EL influyó en el PE de las semillas de cují sin artejo, y en las de carocaro y samán. Se concluye que la EL en las semillas de lara ruidosa, cují sin artejo, carocaro y samán; así como la utilización de semillas de cují con artejo frescas o almacenadas durante tres meses y tratadas con agua caliente por cinco minutos permitieron incrementar la emergencia. Las plántulas mostraron un desarrollo normal y homogéneo.

    Full Text Available Con el propósito de evaluar la capacidad de degradar madera de los moluscos bivalvos perforadores de madera en comunidades de manglar, se realizó un estudio en el manglar Ana María Campos, Lago de Maracaibo, Venezuela, utilizando como sustratos bloques de madera de pino. Dos especie de teredos, Bankia fimbriatula y Psiloteredo healdi fueron encontradas en el manglar de la península Ana María Campos, siendo P. healdi la especie dominante. A pesar de estar presente durante todo el período de estudio su capacidad de invadir sustrato varió y la tasa de consumo de madera fluctuó en función del número de individuos por colector. P. healdi fue capaz de consumir hasta 17.1x10-3 g de madera/individuo/día.The degradation rate of wood substrates by the two species of bivalve molluscan borers, Bankia fimbriatula and Psiloteredo healdi was studied in the mangrove forest of Ana María Campos Peninsula (Lake of Maracaibo, Venezuela. Pine wood substrates were placed in adjacent waters and the rate of infestation and growth (wood consumption was recorded. The second species was dominant and occurred throughout the entire study (april to october, 1993, but rates of larval invasion and growth of individuals were influenced by the size of the population present. P. healdi is capable of consuming as much 17.1x10-3 g of wood/day.

  18. Relative yield-per-recruit and management strategies for Cynoscion acoupa (Perciformes: Sciaenidae in Lake Maracaibo, Venezuela

    Orlando José Ferrer Montaño

    2013-03-01

    Full Text Available Acoupa weakfish, Cynoscion acoupa, in Lake Maracaibo is subject to intense commercial fishing by an artisanal fleet, and a recent decrease in fish size observed from landings is of concern. This fishery has not yet been modeled, and its assessment and the establishment of management practices to overcome the current overfished condition are urgently needed. To address this, we used recent and past empirical growth estimates to model relative yield-per-recruit under different lengths at first capture. Our results from relative yield-perrecruit analysis showed evidence that growth and recruitment overfishing occur under current fishing practices in Lake Maracaibo. Particular attention was given to fishing practices in El Tablazo Bay where young, small fish predominate in the commercial catches (mean total length=33.7cm, well below the length at first sexual maturity (~40cm TL for both sexes. As management strategies, we propose to set a mesh size limit at or above 8.89cm (3.5in, which will reduce fishing mortality of immature fish, increase yield-per-recruit, and will result in an increase of Acoupa weakfish recruitment for the long term in Lake Maracaibo.La curvina, Cynoscion acoupa, en el Lago de Maracaibo se encuentra sometida a una intensa actividad pesquera comercial. No obstante, antes de este estudio no se había examinado el potencial efecto de la sobrepesca a través del modelado. Utilizamos estimados empíricos de crecimiento actuales y pasados para modelar el rendimiento-por-recluta relativo bajo diferentes longitudes de primera captura. Presentamos evidencia a partir de resultados de rendimiento-por-recluta relativo que indica que existe sobrepesca por crecimiento y reclutamiento bajo las prácticas pesqueras actuales en el Lago de Maracaibo. Se puso particular atención a las pesquerías en la Bahía El Tablazo donde predominan peces jóvenes pequeños en las capturas (longitud total promedio=33.7cm, muy por debajo de la longitud de

    The atmospheric gases and aerosols coming from various natural and anthropogenic emissions are incorporated into raindrops through various physicochemical processes during rain events. Knowledge of the chemical composition of precipitation is critical to understand regional and local air pollution and its effects on the ecosystems. Sulfur, nitrogen and chlorine compounds are mainly involved in rain acidity production as acidic or potentially acidic species. An important factor in the acid-base characteristics of rain is the emission of alkaline materials such as calcium-magnesium carbonates and ammonia, generally found as a vapour responsible to sulfuric and nitric acids neutralizing. Rain chemistry reported in this work originates from several sites of the city of Maracaibo and the rainwater samples were gathered in three periods between 1989 and 2001, using manual and automatic samplers. The different analyses were made using a flame atomic absorption spectrometer, Perkin-Elmer 3110 and an ion chromatography equipment with a conductivity detector, Dionex 2000i/SP. The pH-PPV in Maracaibo rainwater was 4.8, indicating an atmosphere lightly acid and influenced by SO{sub 4}{sup -2}, Cl{sup -} and NO{sub 3}{sup -} in 86 %. NH{sub 3} is the most important neutralizing species, though the concentrations of Ca{sup +2} and Mg{sup +2} are additional contributions to atmospheric neutralizing process. The major flow of wet deposition was exhibited by NH{sub 4}{sup +}, SO{sub 4}{sup -2}, Cl{sup -} and NO{sub 3}{sup -} with 67.5 %. Statistically, a high correlation was found between SO{sub 4}{sup *}, Cl{sup *} and NO{sub 3}{sup -} ions with the H{sup +} ion (p<0.05), ratifying its influence in the acidity of Maracaibo's rain. It is concluded that a small fraction of the acid potentially ions contributes to free acidity of the rains, due to the neutralizing capacity of NH{sub 3}, Ca{sup *} and Mg{sup *}.

    Full Text Available INTRODUCCIÓN: el infarto agudo del miocardio constituyó más del 12 % de los fallecimientos por cardiopatía isquémica en Venezuela en 2006, sin evidenciarse disminución en la mortalidad a pesar del mejoramiento tecnológico de los servicios de urgencias. OBJETIVO: caracterizar su comportamiento en los centros de diagnóstico integrales del Estado de Vargas, en el período comprendido de junio de 2006 a junio de 2009. MÉTODOS: se realizó un estudio descriptivo, retrospectivo para caracterizar el comportamiento del infarto agudo del miocardio en los servicios de urgencia y emergencia de los centros de diagnóstico integrales utilizando las estadísticas de la Misión Barrio Adentro. RESULTADOS: fueron atendidos 186 pacientes por infarto agudo del miocardio, predominaron los ingresos en la terapia intensiva (2,4 % sobre los servicios de hospitalización. Los fallecidos por esta causa fueron 35 personas, 17,1 % del total de fallecidos. Fueron trombolizados el 39,2 %, con el mayor número alcanzado en el 2008 con 51,2 %. La letalidad por infarto agudo del miocardio osciló entre tasas de 17,3 y 20 por cada 100 pacientes vistos. La tasa de mortalidad bruta fue de 9,58 x 100 000 habitantes. CONCLUSIONES: el número de casos atendidos por infarto tuvo un comportamiento ascendente de manera estable, representaron el 0,7 % del total de ingresos en estos centros, con predominio de los ingresos en la terapia intensiva sobre los servicios de hospitalización. Se le aplicó el tratamiento trombolítico con estreptoquinasa recombinante a un por ciento importante de enfermos. En los servicios de hospitalización fue superior la letalidad por esta causa. No disminuyó el riesgo de morir para los pacientes con esta enfermedad y la mortalidad general en el período estudiado fue de 35 pacientes para una tasa de 9,58 × 100 000 habitantes.INTRODUCTION: the acute myocardial infarction was over the 12 % of deceased from ischemic heart disease in Venezuela in

  1. [Detection of Entamoeba histolytica and Entamoeba dispar by PCR in children, less than five years of age with diarrhea, in Maracaibo, Venezuela. A preliminary study].

    2013-12-01

    To determine the prevalence of Entamoeba histolytica as a producer of diarrhea, a study was conducted in children, less than five years of age, with diarrhea who attended several out patient clinics of the Servicio Aut6nomo Hospital Universitario, Maracaibo, Venezuela. A macroscopic and microscopic examination with physiological saline, lugol and Kinyoun staining were performed to the stool samples obtained. The remainder of the sample was frozen until DNA extraction, and PCR amplification was performed separately for E. histolytica and E. dispar. Microscopic examination showed no trophozoites and/or cysts of Entamoeba histolytica/dispar/moshkovskii, or intestinal coccidians in any of the 50 samples analyzed. Parasites detected were Giardia lamblia (6%), Blastocystis sp. (4%), Pentatrichomonas hominis (2%), Ascaris lumbricoides (2%) and Trichuris trichiura (2%). By PCR, six samples (12%) had DNA of E. dispar and two (4%) had DNA from E. histolytica; no child showed association of both amoebae. The two children who had E. histolytica were one-year-old. E. dispar was detected in younger children. We suggest that the prevalence of E. histolytica in children under five years is really low.

  2. Honor femenino y economía de bienes simbólicos en Maracaibo, Venezuela, a finales del siglo XIX (1880 – 1900

    Luis Rincón Rubio

    2008-05-01

    Full Text Available Se presenta en este trabajo una aproximación antropológica a las representaciones culturales del honor femenino circulantes en la ciudad de Maracaibo, Venezuela, a finales del siglo XIX. La investigación realizada adopta un enfoque teórico-metodológico de corte estructuralista-constructivista, abordando el orden social como un sistema simbólico organizado según una lógica de la diferencia y partiendo de la premisa de que prácticas y representaciones están orientadas externamente por las estructuras objetivas de la sociedad, e internamente por esquemas de percepción, pensamiento y acción de origen social. Al tratarse de un trabajo de antropología histórica, los informantes fueron sustituidos por fuentes documentales ubicadas en diferentes archivos venezolanos. Se encuentra que las representaciones culturales del honor femenino en la sociedad en cuestión asociaban este concepto con la castidad sexual, reproduciendo esquemas culturales vigentes en la órbita del mundo occidental y proporcionando una lógica para el mantenimiento de relaciones desiguales de género y poder en la vida pública y privada de los marabinos. El capital social y el capital simbólico habrían sido componentes fundamentales del capital total de que se disponía entonces en la lucha cotidiana por la obtención de recursos y por el reconocimiento social, en una economía de bienes simbólicos que atribuía al parecer preferentemente a los hombres el trabajo oficial de conservación o incremento de dichas formas de capital.

    Full Text Available In order to evaluate the analytical performance in the determination of total cholesterol (CT and triglycerides (TG in clinical laboratories in the city of Maracaibo, Venezuela , applying an external quality assessment ( EQA, six comercial controls sera normal (CN and six abnormal (CA were distributed to thirteen laboratories using automated equipment for these measurements. To assess the performance inter-and intralaboratory, the precision was determined through the coefficient of variation (CV and accuracy by calculating the relative percent deviation (DRP. The analytical goal for the interlaboratory evaluation was following Aspen ́s criteria, (CV for CT up to 8.3 % and for TG up to 12.5 % and for intralaboratory using six sigma criteria: 2.8 % for CT and 4.2 % for TG. In interlaboratory precision, the CV obtained was 7.88% and 9.35% for CT and TG, respectively; and for intralaboratory, CV for CT was 4.87% and 5.84% for TG. From the laboratories evaluated, only 15.38% for CT and 46.15% for TG reached the the intralaboratory precision. The percentage of laboratories with acceptable DRP to CT was 73.08% and 92.11% for TG. Most laboratories did not reach the analytical goal in relation to intralaboratory precision and the accuracy was satisfactory for both determinations and both controls. It was concluded that the transferability of results between laboratories in the region is possible for CT and TG, getting the best analytical performance for TG. It was also shown internal quality control failures, requiring the implementation of EQA programs in the region

The research shows an emerging paradigm with an interpretative, quantitative and qualitative focus, which lead to the use of methodological triangulation. This is an exploratory research on its first phase, and a descriptive one on its second phase, the field work. A non-experimental, transversal design was structured. The population was composed by seven (7 Directors: four (4 of hospitals, three (3 of the national health clinics, as well as four hundred (400 patients. The collection of data was carried out through the technique of interviews, with open questions for the first population, so as to measure the quality of service offered by the health centers. The technique used for the second population was a survey and the questionnaire was the instrument. This instrument was structured by means of a scale combination, which allowed first to measure the perception the patients have for the service they receive, and second to determine the factors that impact the quality of this service. The test of dependability was applied by means of the coefficient of the two halves throwing 0.90% for the second. As a conclusion, it was determined that the administrators don’t perceive service as a main variable or strategy, but rather as an obligation, so it is necessary to make changes both at the level of moral values, and at the perceptive process. Therefore, it is recommended that hospitals and national health clinics respond with actions on aspects where

    Agroforestry systems are environment-friendly production systems which help to preserve biodiversity while providing people with a way of earning a living. Cacao is a historically important crop in Venezuela that traditionally has been produced in agroforestry systems. However, few studies have evaluated how different trees used in those systems affect the dynamics and abundance of insects. The present study evaluated the entomofauna assemblages associated with different combinations of four timber-yielding trees and four Criollo cacao cultivars established in a lowland tropical ecosystem in Venezuela. A randomized block design with two replicates was used, each block having 16 plots which included all 16 possible combinations of four native timber trees ( Cordia thaisiana , Cedrela odorata , Swietenia macrophylla , and Tabebuia rosea ) and four Criollo cacao cultivars (Porcelana, Guasare, Lobatera and Criollo Merideño). Insects were collected with yellow pan traps and sorted to order. Coleoptera and parasitoid Hymenoptera were determined to the family level. In total, 49,538 individuals of seven orders were collected, with Hymenoptera, Diptera, and Hemiptera being the most abundant, although only Lepidoptera and Coleoptera abundances were significantly influenced by the timber tree species. Twenty-three families of parasitoid Hymenoptera and 26 of Coleoptera were found. Significant differences in insects’ assemblages were found both in parasitoid Hymenoptera and Coleoptera families associated to every shade tree, with the families Eulophidae and Lycidae being indicators for Cordia , and Chalcididae for Swietenia . The entomofauna relationship with the cacao cultivar was barely significant, although Scydmaenidae and Scarabaeidae were indicators for Lobatera and Merideño, respectively. No significant effects were found for interaction with cacao cultivars and native trees. We concluded that the particular insect assemblages found in Cedrela odorata and Cordia

    Lack of adequate information about the taxonomic and evolutionary relationships, ecology, biology, and distribution of several species belonging to the family Potamotrygonidae makes these species vulnerable to anthropic activities, including commercial overexploitation for the ornamental fish market. The aim of this study was to investigate the systematic relationships among genera and species belonging to this family by analyses of three mitochondrial gene regions. Samples were collected from the main river basins in Colombia and Venezuela for four genera and seven species of the family, as well as for what appear to be unidentified species. Three mitochondrial molecular markers COI, Cytb, and ATP6 were amplified and sequenced. Maximum likelihood and Bayesian inference analysis were performed to obtain topologies for each marker and for a concatenated dataset including the three genes. Small dataset may compromise some methods estimations of sequence divergence in the ATP6 marker. Monophyly of the four genera in Potamotrygonidae was confirmed and phylogenetic relationships among members of the Potamotrygon genus were not clearly resolved. However, results obtained with the molecular marker Cytb appear to offer a good starting point to differentiate among genera and species as a tool that could be used for barcoding. The application of this gene as a barcode could be applied for management and regulation of extraction practices for these genera. Sequencing complete mitochondrial genomes would be the next step for testing evolutionary hypothesis among these genera. Population structure analyses should be undertaken for Paratrygon, Potamotrygon magdalenae and motoro.

    The background notes by the U.S. State Department on Venezuela emphasize the unique economic conditions in this oil-rich nation, and include information on its people, geography, history, government politics, defense and foreign relations. Venezuela, located on the north coast of South America, has 17,791,000 people, growing at a rate of 2.7%. Infant mortality is 2.7/1000, and life expectancy is 70 years. Geography ranges from the scarcely populated highlands between the Orinoco river and Guyana, the Orinoco plains, to the populated Andes mountains and coast. 80% of the population is urban. Literacy is a priority at 88.4%; Technical and university education is increasing; emigration from other countries is common because of relatively good working conditions. Venezuela has a long history of self government, having become independent in 1921. Now the democratic constitutional government is effective in improving both internal and regional development and human rights. The economy is based on oil production and refining, as well as steel and aluminum, all nationalized industries. Self-sufficiency in agriculture is a national goal. Because of the rapid population growth rate, however, per capita income and GNP are stagnating.

    The La Luna Formation, main source rock of the Maracaibo Basin was studied by conventional geochemical parameters, used to determine the maturity, and they were compared with the physic-chemical and molecular properties of the asphaltenes present in the bitumen of the rocks. Three wells were studied (A, B and C) with a total of 13 samples. Based on Rock-Eval results the organic matter in well A (455 deg C Tmax) shows a relatively high level of maturation (top of the oil window), whereas the organic matter in well B (435 - 436 deg C Tmax) is in the beginning of the oil window. Tmax values in well C (438 - 446 deg C) and well C suggest an intermediate maturity level. The biomarkers identified in well B and C show ratios indicating an equilibrium state in the maturity level. A good correlation was found comparing the conventional analytical data with the determination of maturity level obtained from the asphaltenes precipitated from the bitumen of the samples. With increased maturity levels the H1 NMR analysis showed enrichment in aromatic molecules in relation to aliphatic, due to the bitumen aromatization process. Similarly, the asphaltenes molecular weight has higher values in samples characterized by elevated maturity levels. This confirms earlier studies that showed that asphaltenes may be utilized as maturity parameter of organic matter. (author)

  16. Horizontal drilling in Miocene thin sand of Lake Maracaibo

    Partidas, C. [PDVSA Exploration and Production (Venezuela)

    1998-12-31

    Horizontal drilling in the mature Lake Maracaibo field in Venezuela as a means of stimulating production are discussed. The Miocene sand where the horizontal well technology was applied, presented a number of intervals of unconsolidated sand of varied continuity, pay intervals at ten to twenty feet thickness, and reservoir pressures mostly at hydrostatic or below hydrostatic values. This paper evaluates a horizontal drilling program in the Lagunallis Lago Production Unit of Maracaibo, involving 91 wells to date (since 1995). When assessed in economic terms, results indicate that horizontal wells are a better economic alternative than vertical wells. The same results also showed that drainage from thin sand reservoirs resulted in better production with horizontal well technology than production from vertical wells. Payout was less than two years for 50 per cent of the horizontal wells while 40 per cent had payouts of between two and four years. Profit to investment ratio was greater than two in the case of about 70 per cent of the horizontal wells drilled in 1996. 2 tabs., 10 figs.

    Full Text Available The objective of the investigation was to evaluate the suitability of the water for human consumption in the community of San Valentin which is located in the sector of Ancon Bajo II, in the municipality of Maracaibo in Venezuela. Ten samples of different water supply sources were tested and evaluated from the physical, chemical and bacteriological points of view. The standard method was used for the analysis. The test results were compared with the values set by Venezuelan Drinking Water Quality Standards and water quality catalogues issued by the World Health Organization. It is concluded that the water supply pipe requires an overall conventional treatment for purification while pit water requires desalinization treatment. Irragorry ravine is highly contaminated so it is not an alternative water supply source.

    Full Text Available INTRODUCTION: Obesity is a worldwide public health issue. Since the epidemiological behaviour of this disease is not well established in our country, the purpose of this study was to determinate its prevalence in the Maracaibo City, Zulia State- Venezuela. MATERIALS AND METHODS: A cross-sectional study was undertaken using the data set from the Maracaibo City Metabolic Syndrome Prevalence Study. The sample consists of 2108 individuals from both genders and randomly selected: 1119 (53.09% women and 989 (46.91% men. The participants were interrogated for a complete clinical history and anthropometric measurements. To classify obesity, the WHO criteria for Body Mass Index (BMI, and Waist Circumference (WC from the IDF/NHLBI/AHA/WHF/IAS/IASO-2009 (IDF-2009 and ATPIII statements were applied. RESULTS: For BMI, obesity had an overall prevalence of 33.3% (n = 701, and according to gender women had 32.4% (n = 363 and men had 34.2% (n = 338. Overweight had a prevalence of 34.8% (n = 733, Normal weight had 29.8% (n = 629, and Underweight had 2.1% (n = 45. Adding Obesity and Overweight results, the prevalence of elevated BMI (>25 Kg/m(2 was 68.1%. Using the IDF-2009 WC's cut-off, Obesity had 74.2% prevalence, compared to 51.7% using the ATPIII parameters. CONCLUSIONS: These results show a high prevalence of abdominal obesity in our locality defined by the WHO, IDF-2009 and ATPIII criteria, which were not designed for Latin-American populations. We suggest further investigation to estimate the proper values according to ethnicity, genetic background and sociocultural aspects.

  2. Zulia rich coal seams to fuel Venezuela

    1983-06-16

    In March, 1982, Carbozulia awarded a contract to Fluor Corp. to provide basic engineering services, including mine planning and geology, for the two-phase project. The open pit mine and ancillary facilities, valued at more than $200 million, will provide steam and metallurgical coal for domestic use. The site, Mina Paso Diablo, is located about 60 miles northwest of Maracaibo. Upon phase one completion sometime in 1987, the mill will start production, gradually increasing to 4 million metric-tons-per-year. This will increase to 6.4 million metric tons when phase two is completed. In addition to the mine, the Venezuelan government plans to build an industrial complex along Lake Maracaibo. Corpozulia will build a steel-rolling mill and add a 350,000 metric tons-per-year coking oven, which will consume about 7% of the mine's metallurgical-coal production. Another government-owned firm, Electric Energy of Venezuela, plans to build a thermo-electric plant nearby. Two 250-megawatt units are planned initially, with potential to add another six units. At full capacity, the plant will burn more than 90% of the coal produced from the mine. Mina Paso Diablo contains one of Latin America's largest proven coal reserves - about 350 million metric tons - with guesstimates running as high as 4 billion metric tons for the Zulia coal basin. The coal is of superior quality, running about 12,000 to 13,000 Btu's per lb. with a low ash and sulphur content.

  5. Republic of Venezuela. Country profile.

    Hakkert, R

    1985-06-01

    Venezuela's current economic and demographic situation is described. Venezuela is a major oil country, and the oil industry accounts for 90% of the country's foreign exchange, 70% of the government's revenues, and 15% of the gross domestic product. The economy experienced a sudden and high rate of economic growth in the mid-1970s as a result of high oil prices; however, in recent years, declining oil prices have had a negative effect on the economy. The country is now faced with a serious trade deficit, and the government recently imposed restrictions on imports. Imports in recently years had increased markedly. The emphasis on the oil industry weakened the agricultural sector and, as a result, food imports increased. In addition, the rapid economic growth experienced during the 1970s greatly increased the demand for imported consumer goods. Venezuela has the 4th highest foreign debt in the world (US$35 billion). Despite these problems Venezuela has a relatively high per capita income (US$4,140) and living standard, compared to other countries in the region. Venezuela's total population is 14.6 million, and the population is unevenly distributed. 86% of the population lives in cities of 2500 or more. 37.4% of the population and 70% of the industry is concentrated in the Federal District which contains Caracas, and in the surrounding states of Aragua, Miranda, and Carabobo. This area constitutes only 2.36% of the country's territory. Most of the oil fields are located in the state of Zulia which also contains the country's 2nd largest city (Maracaibo). The country's coastal area contains most of the agricultural lands, and the prairies just south of the coastal mountain ranges are devoted primarily to cattle raising. The remaining 58.2% of the country's territory is essentially jungle and contains only 6.9% of the country's population. The annual population growth rate is 3.11%. Although the rate declined in recent years it is higher than in most of the other

  12. Monitoring of Land Deformation Due to Oil Production by InSAR Time Series Analysis Using PALSAR Data in Bolivarian Republic of Venezuela

    Deguchi, Tomonori; Narita, Tatsuhiko

    2015-05-01

    The target area of this study is the Maracaibo sedimentary basin located in the western part of Bolivarian Republic of Venezuela. The full-scale exploration and development for oil resources in Venezuela which was the greatest oil-producing country in South America had begun at the Maracaibo sedimentary basin in the 1910s, and it was a center of the oil product in Venezuela until the 1980s. But, in most of oil fields in the Maracaibo sedimentary basin, there is concern over the drain on recoverable reserves due to deterioration, and the production amount of petroleum in Venezuela has been diminishing these days. Leveling and GPS surveying were carried out in the past, and they revealed that the large-scale subsidence phenomenon of which cumulative subsidence amount was approximately 5 meter had occurred. The authors applied the vertical displacement measurement by InSAR time series analysis using PALSAR data obtained in the Fine-beam and ScanSAR observation mode. As a result, it could be confirmed clear ground deformation in the surrounding of three oil fields (Tia Juana, Lagunillas and Bachaquero) and easily recognized that the areas of phase anomalies detected by this analysis had expanded and the number of interference fringes had increased over time. The annual velocity of vertical ground surface displacement measured by InSAR time series analysis was -51 mm per year, -103 mm per year and -58 mm per year in Tia Juana, Lagunillas and Bachaquero oil field respectively. The tendency that an earth surface shifted towards the center of phase anomalies was detected from the result of the horizontal ground change measurement. It was interpreted from Google Earth and Landsat images that oil-related facilities (mainly bowling stations) were built intensively over the areas where phase anomalies were detected. Therefore, it was inferred that there was a high association between the operation activity of the oil field and ground deformation. In addition, the deterioration

  13. [Immigration to Venezuela].

    Picouet, M; Pellegrino, A; Papail, J

    1986-11-01

    Immigration to Venezuela is examined using census data with the focus on the period 1971-1981. A brief overview of trends since the beginning of the twentieth century is first presented. The analysis indicates that "immigration to Venezuela is clearly of a short-term nature. Flows follow job opportunities and adjust to the labour market and to the financial capacity of the exchange market. The large increase of migratory movements to Venezuela in the 1970's is characterized by a diversification of their places of origin and by a greater instability. To a large extent, the migrants are illegal, especially those coming from Colombia and the Caribbean islands. Because of the crisis of the early 1980's, which is now worsened by the down trend of both oil prices and the U.S. dollar, Venezuela has become less attractive to immigrants, particularly from neighbouring countries." The authors observe that migrants in Venezuela are not well integrated and may depart, disrupting the labor supply in certain technical and specialized occupations (SUMMARY IN ENG AND SPA) excerpt

  14. LDC nuclear power: Venezuela

    Roche, M.

    1982-01-01

    Venezuela had an aggressive nuclear program when it was under a dictatorship in the 1950s, but it is currently assuming a wait-and-see stance. The country has one small research reactor, but it may have a reactor on-line in the mid-1990s. CONADIN, Venezuela's nuclear energy planning agency, has commissioned feasibility studies and requested proposals for a reactor-siting survey. A recent study for the Venezuelan state oil company suggests tha a natural-uranium, gas-cooled reactor could provide process steam to extract oil from the bituminous tar sands of the Orinoco Basin. Venezuela is also exploring for uranium reserves. 23 references, 1 figure, 2 tables

  15. Distribution, status, and traditional significance of the West Indian manatee Trichechus manatus in Venezuela

    O'Shea, Thomas J.; Correa-Viana, Martín; Ludlow, Mark E.; Robinson, John G.

    1988-01-01

    Aerial and interview surveys were conducted in 1986 to determine the current distribution, status, and traditional significance of the West Indian manatee Trichechus manatus in Venezuela. Aerial surveys provided just eight tentative sightings in 73 hours of searching. These discouraging results may have been due to poor visibility, small populations, and perhaps reduced dry season manatee activity. Results of interview surveys, however, permitted a number of important generalizations. A remnant manatee population exists in Lake Maracaibo, but none occur along the more than 1500 km of Caribbean coastline. Abundance is greatest in eastern Venezuela bordering the Golfo de Paria, in the Orinoco Delta, and in the middle Orinoco and tributaries. Local market hunting in the middle of this century probably greatly reduced manatee populations in these areas. Recent protection laws, education efforts, and manatee scarcity have resulted in a declining interest in manatee hunting. Much excellent manatee habitat persists in these regions, and a continued decline in hunting could result in an optimistic outlook for future manatee populations if the incidental take in net fisheries is controlled. Traditional beliefs and legends concerning manatees in Venezuela, including hunting taboos, show that these animals remain a colorful part of the folk culture. However, manatee protection does not pose economic hardships or infringe upon traditional spiritual beliefs.

  18. Seasonal prediction of lightning activity in North Western Venezuela: Large-scale versus local drivers

    Muñoz, Á. G.; Díaz-Lobatón, J.; Chourio, X.; Stock, M. J.

    2016-05-01

    The Lake Maracaibo Basin in North Western Venezuela has the highest annual lightning rate of any place in the world (~ 200 fl km- 2 yr- 1), whose electrical discharges occasionally impact human and animal lives (e.g., cattle) and frequently affect economic activities like oil and natural gas exploitation. Lightning activity is so common in this region that it has a proper name: Catatumbo Lightning (plural). Although short-term lightning forecasts are now common in different parts of the world, to the best of the authors' knowledge, seasonal prediction of lightning activity is still non-existent. This research discusses the relative role of both large-scale and local climate drivers as modulators of lightning activity in the region, and presents a formal predictability study at seasonal scale. Analysis of the Catatumbo Lightning Regional Mode, defined in terms of the second Empirical Orthogonal Function of monthly Lightning Imaging Sensor (LIS-TRMM) and Optical Transient Detector (OTD) satellite data for North Western South America, permits the identification of potential predictors at seasonal scale via a Canonical Correlation Analysis. Lightning activity in North Western Venezuela responds to well defined sea-surface temperature patterns (e.g., El Niño-Southern Oscillation, Atlantic Meridional Mode) and changes in the low-level meridional wind field that are associated with the Inter-Tropical Convergence Zone migrations, the Caribbean Low Level Jet and tropical cyclone activity, but it is also linked to local drivers like convection triggered by the topographic configuration and the effect of the Maracaibo Basin Nocturnal Low Level Jet. The analysis indicates that at seasonal scale the relative contribution of the large-scale drivers is more important than the local (basin-wide) ones, due to the synoptic control imposed by the former. Furthermore, meridional CAPE transport at 925 mb is identified as the best potential predictor for lightning activity in the Lake

    No federal government officials showed up at the Oct. 29 ceremony to lauch the Responsabilidad Integral program of Asoquim, the Venezuelan chemical industry association. But that did not discourage industry representatives. Industry has tried to keep the Ministry of Environment Affairs involved as much as possible, says Danay Zoppi de Perez, corporate v.p. with Grupo Quimico. But industry was proud to be doing it anyway, despite the absence of government. It's a private, proactive initiative. Asoquim's program is based on the six Responsible Care codes. At the ceremony, 56 companies from Asoquim's membership of 150, which represents 90% of chemicals production in the country, signed on. Signatories include stateowned Petroquimica de Venezuela (Pequiven), domestic private-sector firms, and most of the multinationls operating in Venezuela.

    Strong performances by small and medium sized oil companies in Venezuela have contributed to the success of its oil industry. This paper considers the historical progress of the industry since its nationalisation twenty-one years ago, charting its attractiveness to investors and plans for expansion. Its very success has brought the Venezuelan oil industry into conflict with OPEC's quota system, which it argues, needs to be charged. (UK)

    Percent variation of the consumer price index (CPI) is the inflation indicator most widely used. This indicator, however, has some drawbacks. In addition to measurement errors of the CPI, there is a problem of incongruence between the definition of inflation as a sustained and generalized increase of prices and the traditional measure associated with the CPI. We use data from 1991 to 2005 to estimate a complementary indicator for Venezuela, the highest inflation country in Latin America. Late...

  2. HYDROCARBONS RESERVES IN VENEZUELA

    Gonzalez Cruz, D.J.

    2007-07-01

    Venezuela is an important player in the energy world, because of its hydrocarbons reserves. The process for calculating oil and associated gas reserves is described bearing in mind that 90% of the gas reserves of Venezuela are associated to oil. Likewise, an analysis is made of the oil reserves figures from 1975 to 2003. Reference is also made to inconsistencies found by international experts and the explanations offered in this respect by the Ministry of Energy and Petroleum (MENPET) and Petroleos de Venezuela (PDVSA) regarding the changes that took place in the 1980s. In turn, Hubbert's Law is explained to determine peak production of conventional oil that a reservoir or field will reach, as well as its relationship with remaining reserves. Emphasis is placed on the interest of the United Nations on this topic. The reserves of associated gas are presented along with their relationship with the different crude oils that are produced and with injected gas, as well as with respect to the possible changes that would take place in the latter if oil reserves are revised. Some recommendations are submitted so that the MENPET starts preparing the pertinent policies ruling reserves. (auth)

  3. Country watch: Venezuela.

    1996-01-01

    Since 1990, ACCSI has worked to safeguard the rights of people living with HIV/AIDS in Venezuela. The Pan American Health Organization (PAHO) had recognized ACCSI's program by 1992, enabling the nongovernmental organization (NGO) to establish fixed office hours during which it can receive clients. ACCSI does not distinguish between people living with HIV/AIDS and others, but considers it important to regulate AIDS as a public health issue within the context of human rights and ethics. Almost all of the Legal Office's initial cases were related to discrimination in the workplace, health centers, and educational institutions, but the ACCSI now also addresses family problems related to adoption, insurance, and inheritance, among others. To cope with the increase in service caseload, services have been extended through collaboration with specialized organizations concerned with human rights, women, children, prisons, and indigenous people. ACCSI influences governmental policy-making through its participation in the National AIDS Program. Moreover, ACCSI's networking activities ensure that the topic of HIV/AIDS and human rights is now always included in seminars and conferences in Venezuela, even when they are concerned with sexually transmitted diseases or other medical issues. Almost every time the press report upon AIDS, they consult the NGO. Everyday more people in Venezuela are standing up for their rights and denouncing discrimination against people infected with HIV.

    The incidence of type 2 diabetes (T2D) and its economic burden have increased in Venezuela, posing difficult challenges in a country already in great turmoil. The aim of this study was to review the prevalence, causes, prevention, management, health policies, and challenges for successful management of diabetes and its complications in Venezuela. A comprehensive literature review spanning 1960 to 2015 was performed. Literature not indexed also was reviewed. The weighted prevalence of diabetes and prediabetes was estimated from published regional and subnational population-based studies. Diabetes care strategies were analyzed. In Venezuela, the weighted prevalence of diabetes was 7.7% and prediabetes was 11.2%. Diabetes was the fifth leading cause of death (7.1%) in 2012 with the mortality rate increasing 7% per year from 1990 to 2012. In 2012, cardiovascular disease and diabetes together were the leading cause of disability-adjusted life years.T2D drivers are genetic, epigenetic, and lifestyle, including unhealthy dietary patterns and physical inactivity. Obesity, insulin resistance, and metabolic syndrome are present at lower cutoffs for body mass index, homeostatic model assessment, and visceral or ectopic fat, respectively. Institutional programs for early detection and/or prevention of T2D have not been established. Most patients with diabetes (∼87%) are cared for in public facilities in a fragmented health system. Local clinical practice guidelines are available, but implementation is suboptimal and supporting information is limited. Strategies to improve diabetes care in Venezuela include enhancing resources, reducing costs, improving education, implementing screening (using Latin America Finnish Diabetes Risk Score), promoting diabetes care units, avoiding insulin levels as diagnostic tool, correct use of oral glucose tolerance testing and metformin as first-line T2D treatment, and reducing health system fragmentation. Use of the Venezuelan adaptation of

    There are few longitudinal studies of dementia in developing countries. We used longitudinal data from the Maracaibo Aging Study to accurately determine the age- and sex-specific incidence of dementia in elderly Latin Americans. The Diagnostic and Statistical Manual of Mental Disorders (Fourth Edition, Text Revision) was used to diagnose dementia, which was classified as Alzheimer's disease, vascular dementia, or other. Age- and sex-specific incidence was estimated as the number of new cases of dementia divided by person-years (p-y) of follow-up. The incidence of all dementia diagnoses was 9.10 per 1000 p-y (95% confidence interval [CI] 7.13-11.44; 8026 total p-y), 5.18 for Alzheimer's disease (95% CI 3.72-7.03; 7916 total p-y), and 3.35 for vascular dementia (95% CI 2.19-4.91; 7757 total p-y). Among Maracaibo Aging Study participants younger than 65 years, the incidence of dementia was higher than that of US Whites. Among individuals older than 65 years, the incidence was comparable to the mean of previous incidence estimates for other populations worldwide. Copyright © 2017 the Alzheimer's Association.

  14. Pleistocene slip rates on the Boconó fault along the North Andean Block plate boundary, Venezuela

    Pousse-Beltran, Lea; Vassallo, Riccardo; Audemard, Franck; Jouanne, François; Carcaillet, Julien; Pathier, Erwan; Volat, Matthieu

    2017-07-01

    The Boconó fault is a strike-slip fault lying between the North Andean Block and the South American plate which has triggered at least five Mw > 7 historical earthquakes in Venezuela. The North Andean Block is currently moving toward NNE with respect to a stable South American plate. This relative displacement at 12 mm yr-1 in Venezuela (within the Maracaibo Block) was measured by geodesy, but until now the distribution and rates of Quaternary deformation have remained partially unclear. We used two alluvial fans offset by the Boconó fault (Yaracuy Valley) to quantify slip rates, by combining 10Be cosmogenic dating with measurements of tectonic displacements on high-resolution satellite images (Pleiades). Based upon a fan dated at >79 ka and offset by 1350-1580 m and a second fan dated at 120-273 ka and offset by 1236-1500 m, we obtained two Pleistocene rates of 5.0-11.2 and <20.0 mm yr-1, consistent with the regional geodesy. This indicates that the Boconó fault in the Yaracuy Valley accommodates 40 to 100% of the deformation between the South American plate and the Maracaibo Block. As no aseismic deformation was shown by interferometric synthetic aperture radar analysis, we assume that the fault is locked since the 1812 event. This implies that there is a slip deficit in the Yaracuy Valley since the last earthquake ranging from 1 to 4 m, corresponding to a Mw 7-7.6 earthquake. This magnitude is comparable to the 1812 earthquake and to other historical events along the Boconó fault.

  15. Lithospheric Expressions of the Precambrian Shield, Mesozoic Rifting, and Cenozoic Subduction and Mountain Building in Venezuela

    Levander, A.; Masy, J.; Niu, F.

    2013-05-01

    The Caribbean (CAR)-South American (SA) plate boundary in Venezuela is a broad zone of faulting and diffuse deformation. GPS measurements show the CAR moving approximately 2 cm/yr relative to SA, parallel to the strike slip fault system in the east, with more oblique convergence in the west (Weber et al., 2001) causing the southern edge of the Caribbean to subduct beneath northwestern South America. The west is further complicated by the motion of the triangular Maracaibo block, which is escaping northeastward relative to SA along the Bocono and Santa Marta Faults. In central and eastern Venezuela, plate motion is accommodated by transpression and transtension along the right lateral San Sebastian- El Pilar strike-slip fault system. The strike-slip system marks the northern edge of coastal thrust belts and their associated foreland basins. The Archean-Proterozoic Guayana Shield, part of the Amazonian Craton, underlies southeastern and south-central Venezuela. We used the 87 station Venezuela-U.S. BOLIVAR array (Levander et al., 2006) to investigate lithospheric structure in northern South America. We combined finite-frequency Rayleigh wave tomography with Ps and Sp receiver functions to determine lithosphere-asthenosphere boundary (LAB) depth. We measured Rayleigh phase velocities from 45 earthquakes in the period band 20-100s. The phase velocities were inverted for 1D shear velocity structure on a 0.5 by 0.5 degree grid. Crustal thickness for the starting model was determined from active seismic experiments and receiver function analysis. The resulting 3D shear velocity model was then used to determine the depth of the LAB, and to CCP stack Ps and Sp receiver functions from ~45 earthquakes. The receiver functions were calculated in several frequency bands using iterative deconvolution and inverse filtering. Lithospheric thickness varies by more a factor of 2.5 across Venezuela. We can divide the lithosphere into several distinct provinces, with LAB depth

    Drug-induced liver injury (DILI) is an important cause of morbidity and mortality worldwide, with varied geographical differences. The aim of this prospective, descriptive, cross-sectional study was to identify and characterize cases of DILI in a hospital of Zulia state, Venezuela. Thirteen patients with a presumptive diagnosis of DILI attended by the Department of Gastroenterology, Hospital Universitario, Zulia state, Venezuela, from December-2012 to December-2013 were studied. Ibuprofen (n = 3; 23.1%), acetaminophen (n = 3; 23.1), isoniazid (n = 2; 15.4%) and Herbalife products (n = 2; 15.4%) were the main drugs involved with DILI. Acetaminophen and ibuprofen showed a mixed pattern of liver injury (n = 3; 23.1%) and isoniazid presented a hepatocellular pattern (n = 2; 15.4%). The CIOMS/RUCAMS allowed the identification of possible (n = 7; 53.9%), probable (n = 4; 30.8%) and highly-probable cases (n = 2; 15.4%) of DILI. Amoxicillin/clavulanate, isoniazid, isotretinoin, methotrexate and Herbalife nutritional products were implicated as highly-probable and probable agents. The highest percentage of DILI corresponded to mild cases that recovered after the discontinuation of the agent involved (n = 9; 69.3%). The consumption of Herbalife botanical products is associated with probable causality and fatality (n = 1; 7.7%). In conclusion, the frequency of DILI cases controlled by the Department of Gastroenterology of the Hospital Universitario of Maracaibo was low, being ibuprofen, acetaminophen, isoniazid and products Herbalife the products most commonly involved. It is recommended to continue with the prospective registration of cases, with an extended follow up monitoring period and to facilitate the incorporation of other hospitals in the Zulia State and Venezuela.

    To determine which nocturnal blood pressure (BP) parameters (low levels or extreme dipper status) are associated with an increased risk of glaucomatous damage in Hispanics. Observational cross-sectional study. A subset (n = 93) of the participants from the Maracaibo Aging Study (MAS) who met the study eligibility criteria were included. These participants, who were at least 40 years of age, had measurements for optical tomography coherence, visual field (VF) tests, 24-hour BP, office BP, and intraocular pressure 20% compared with daytime BP) were significant risk factors for glaucomatous damage (odds ratio, 19.78 and 5.55, respectively). In this population, the link between nocturnal BP and GON is determined by extreme dipping effects rather than low nocturnal BP levels alone. Further studies considering extreme decreases in nocturnal BP in individuals at high risk of glaucoma are warranted. Copyright © 2017 American Academy of Ophthalmology. Published by Elsevier Inc.

  7. Venezuela natural gas outlook

    Silva, P.

    1991-01-01

    This paper reports on the natural gas outlook for Venezuela. First of all, it is very important to remember that in the last few years we have had frequent and unforeseen changes in the energy, ecological, geopolitical and economical fields which explain why all the projections of demand and prices for hydrocarbons and their products have failed to predict what later would happen in the market. Natural gas, with its recognized advantages over other traditional competitors such as oil, coal and nuclear energy, is identified as the component that is acquiring more weight in the energy equation, with a strengthening projection, not only as a resource that covers demand but as a key element in the international energy business. In fact, natural gas satisfies 21% of overall worldwide energy consumption, with an annual increase of 2.7% over the last few years, which is higher than the global energy growth of other fossil fuels. This tendency, which dates from the beginning of the 1980's, will continue with a possibility of increasing over the coming years. Under a foreseeable scenario, it is estimated that worldwide use of natural gas will increase 40% over the next 10 years and 75% on a longer term. Specifically for liquid methane (LNG), use should increase 60% during this last decade. The LPG increase should be moderate due to the limited demand until 1995 and to the stable trends that will continue its use until the end of this century

    2014-03-01

    Full Text Available In the above article author describes evolution of legal regulation of international commercial arbitration in Venezuela. Author cites statistics of arbitration centers in Venezuela activities. In past two decades many Latin American countries have reformed their arbitration law. In an effort to modernize its arbitral institutions several Latin American countries adopted Model Law on International Commercial Arbitration of the UN Commission on International Trade Law (UNCITRAL. In addition, many Latin American countries have adopted the monistic system. Author pays detailed attention to this issue, discusses concept of a monistic system - a system in which a unique set of rules governs both domestic and international arbitration. Author argues that legal system of Venezuela fits this definition. Venezuelan law on arbitration in 1998 makes no distinction between domestic and international arbitration. Arbitration was included in judicial system under the Constitution of Venezuela of the 1999. Art. 258 of the Venezuelan Constitution states that arbitration, conciliation and mediation are alternative ways of resolving disputes.

  1. Nuevos antiagregantes plaquetarios en síndrome coronario agudo

    Andrés F Buitrago

    2013-06-01

    Full Text Available En la actualidad las enfermedades cardiovasculares son la principal causa de muerte en los países industrializados y para 2020, lo serán en países en vía de desarrollo. El síndrome coronario agudo se caracteriza por la ruptura o erosión de una placa aterosclerótica que trae consigo grados variables de trombosis y embolización distal, que llevan a una disminución en la perfusión miocárdica. Posterior a la disrupción vascular, empieza un proceso de agregación, activación y adhesión plaquetaria que inicia la formación del trombo mural. Dado que el primer paso en la formación del trombo coronario involucra la activación y la agregación plaquetaria, el tratamiento con medicamentos antiplaquetarios es una de las piedras angulares del síndrome coronario agudo. La antiagregación dual con ácido acetil salicílico y un inhibidor del receptor P2Y12, hacen parte del manejo actual de los pacientes con síndrome coronario agudo y de aquellos sometidos a intervención coronaria percutánea. El clopidogrel es el inhibidor del receptor P2Y12 más utilizado; sin embargo, sus beneficios clínicos se ven limitados por varios factores que interfieren con la conversión del medicamento a su metabolito activo. Es por esto que recientemente se han desarrollado nuevos inhibidores del receptor P2Y12, como prasugrel y ticagrelor, con un efecto antiplaquetario más potente y mayores beneficios clínicos. Las actualizaciones recientes de las guías de manejo basadas en la evidencia los han incluido como parte del tratamiento de esta patología con un grado de recomendación incluso mayor que el de clopidogrel.

    Sporotrichosis is one of the most common subcutaneous mycoses in Venezuela. It is a granulomatous chronic infection with cutaneous or subcutaneous tissue lesions. Regional lymphatic involvement may be present; extracutaneous disease is rare. The causal fungus Sporothrix schenckii has been isolated from soil, vegetation, and animals on numerous occasions and in many localities throughout the world. The aim of this study is to describe clinical and epidemiological features of cases of sporotrichosis observed in Venezuela and review of the literature. We included the demographic data, clinical features, diagnostic methods, treatment, and follow-up of patients with sporotrichosis from 1963 to 2009, diagnosed at the Department of Medical Mycology. One-hundred and thirty-three sporotrichosis cases were diagnosed. Most patients were under the age of 30 years (66.15%). In 61.6% of them, the mode of transmission was not identified. The predominant clinical form in this population was lymphocutaneous (63.15%). Direct microscopic diagnosis was performed in 123 cases, and 57.9% yielded positive results for asteroid body. Sporotrichosis is an endemic subcutaneous mycosis in Venezuela. There are no reports to this date of disseminated forms of the disease, even amongst patients with acquired immunodeficiency syndrome. Direct microscopic examination of wet mount slides with saline solution or distilled water in the search for asteroid bodies is paramount. Saturated sodium and potassium iodine solutions continue to be extremely efficacious and affordable to most of our patients, therefore our treatment of choice. © 2013 The International Society of Dermatology.

  9. Venezuela opens up to explorers

    Kielmas, M.

    1995-01-01

    The opening of Venezuela's first exploration bidding round since oil nationalisation in 1976 was a turning-point in the country's energy policy. The state oil company, Petroleos de Venezuela (PdVSA), has said that the bidding round could generate investment of some $11 billion eventually in development investment and that over the next 10 years, nearly 20 percent of a planned $55 billion, 10-year state oil company investment programme could also come from foreign or private sector oil investment. Should this optimistic prediction materialise, Venezuela, whose 2.75 million b/d oil production in October was some 400,000 b/d over its Opec quota, will remain both the dominant oil producer in Latin America and the top-ranking oil exporter to the US market. In May this year, Venezuelan oil exports topped 1.43 million b/d, or some 16.8 percent of the US market, compared with Saudi Arabia's 15.7 percent. (author)

Se estima que en los países desarrollados una de cada 4 personas ha utilizado drogas recreativas en algún momento de su vida. Por tanto, es frecuente que los médicos se enfrenten a cuadros de intoxicación secundaria al abuso de estas drogas. Además de sus efectos en el sistema nervioso central, también producen cambios significativos a nivel cardiovascular, responsables de una cantidad no despreciable de morbimortalidad relacionada con estas. En este artículo se expone un caso de infarto agudo de miocardio secundario al consumo de heroína, se revisan los efectos sistémicos de esta droga y se examinan el manejo y los mecanismos estudiados que explican esta relación.

  16. Importance of energy efficiency in Venezuela

    Corrie, R.

    1991-01-01

    Venezuela's economic development relies heavily on oil. The nation's energy production equals 3.5 million barrels of oil equivalent (boe) per day. Oil comprises 71% of the energy Venezuela produces, natural gas 20%, hydro 9% and coal 1%. Of the energy produced, Venezuela exports three quarters and consumes the remainder. Over 99% of Venezuela's energy exports are crude oil and oil products. Economic problems have constrained Venezuela's development in recent years. Saddled with an external debt of $US 32 billion, Venezuela will continue to encounter barriers for years to come. The nation is, however, in the process of restructuring its economy. As part of this process, the Venezuelan government has begun to integrate opportunities for improving the efficiency of its energy use. As a major oil producer and exporter, Venezuela is conscious of its responsibility to the international community to limit its emissions of energy-related CO 2 into the atmosphere. For this reason, the Venezuelan government is in the process of creating a program to conserve and ration the use of energy. This effort incorporates a number of measures including the substitution of natural gas for liquid fuels for all end uses (including transportation activities), the increased reliance on hydropower in the generation of electricity and the reduction of waste in the production of natural gas to 2% of the economically recollectable volume

  17. Quality of democracy in Venezuela

    Daniel H. LEVINE

    2013-01-01

    Full Text Available Discussions of democracy in contemporary Venezuela lack a settled definition of the subject, how to study it, or indeed of what counts as «democracy» in the first place. The regime has been described as everything from participatory democracy, hybrid, mixed, and personalist to populist, illiberal, or no longer democratic but rather competitive authoritarian. The goal of this article is to measure the quality of democracy in Venezuela, within the terms of a procedural concept of democracy as detailed in our earlier work. Empirical measurement of the quality of democracy on five dimensions (electoral choice, participation, responsiveness, accountability, sovereignty reveals a low level overall and deep institutional weakness under a personalist leadership, with little change from 2005 to 2010. Future scenarios, after the 2012 presidential election result, include reinforcement of authoritarian trends, open militarization, liberalization and institutional strengthening, or long term volatility and polarized conflict. All scenarios are contingent on the health of President Chávez, who is a central unifying factor for his movement and regime

    2012-04-01

    Full Text Available OBJECTIVE: To describe the epidemiological and clinical characteristics of Venezuelan pediatric patients with multiple sclerosis (MS. METHODS: Database records from the National Program for MS were searched for patients with an established diagnosis of MS whose first symptoms appeared before age 18. RESULTS: The national database held records of 1.710 patients; 3.8% had onset of the first symptoms before age 18. 46.7% were boys, yielding an F:M ratio of 1.13:1. Many children had a disease onset characterized by motor impairment (30.7%, brainstem/cerebellum and spinal cord affectation (27.6%, headache (26%. Less frequent symptoms were sensory symptoms (8% and optic neuritis (7%. DISCUSSION: Pediatric MS patients in Venezuela represent a significant proportion of all MS cases. The clinical pattern is characterized by motor symptoms at onset, and predominantly monosymptomatic presentation with a relapsing-remitting pattern. This is the first systematic attempt to estimate the prevalence of pediatric MS in Venezuela.

  19. Venezuela: World Oil Report 1991

    Anon.

    1991-01-01

    This paper reports on Venezuela's expansion by state oil company PDVSA has gone from a mere concept a year ago to a well-defined plan. The five-year project that began this year and runs through 1995 received a $4-billion upgrading last fall to $25 billion. Money will be spent in increments of $5 billion/year, and all sectors are involved. Largest share, about $10.5 billion, will go to upstream projects, with $6 billion to be invested in refining, $6 billion in petrochemicals, $1.5 billion in coal and $800 million in domestic marketing. PDVSA intends to finance most of the spending directly from its cash flow. The upstream spending will go toward boosting oil production to more than 3.6 MMbpd by the beginning of 1996, with capacity topping at 4.2 MMbopd. Such heavy spending should prove a boon to the Venezuelan economy. The oil industry constitutes 23% of Venezuela's GNP, accounts for 75% of governmental revenues and produces 70% of the nation's annual foreign exchange earnings. The Ministry of Planning already is forecasting a 7% leap in real growth of the GNP this year

    Differential identification of Entamoeba histolytica and Entamoeba dispar is essential for both appropriate patient treatment and epidemiological purposes. To determine the prevalence of these amoeba infections in Santa Rosa de Agua (Maracaibo, Zulia State, Venezuela), a PCR assay using specific primers for each species was standardized and applied. 204 stool samples were analyzed through direct microscopic examination with SSF (0.85%) and lugol, formol-ether concentration, and PCR. Under direct microscopy, 42 individuals (20.58%) presented the E. histolytica/E. dispar complex. Meanwhile PCR showed 47 positive cases for these amoebas: 22 E. histolytica (10.78%), 16 E. dispar (7.84%), and 9 (4.41%) mixed infections. There was no significant difference in the presence of E. histolytica and/or E. dispar according to either gender or age. There were no cases of these amoebas in children under 2 years of age. Observed frequency of E. histolytica (31/204) shows the endemic nature of amoeba infection in this community.

    Full Text Available Based on LANDSAT ETM and Digital Elevation Model (DEM data derived by the Shuttle Radar Topography Mission (SRTM, 2000 of the coastal areas of Northern Venezuela were investigated in order to detect traces of earlier tsunami events. Digital image processing methods used to enhance LANDSAT ETM imageries and to produce morphometric maps (such as hillshade, slope, minimum and maximum curvature maps based on the SRTM DEM data contribute to the detection of morphologic traces that might be related to catastrophic tsunami events. These maps combined with various geodata such as seismotectonic data in a GIS environment allow the delineation of coastal regions with potential tsunami risk. The LANDSAT ETM imageries merged with digitally processed and enhanced SRTM data clearly indicate areas that might be prone by flooding in case of catastrophic tsunami events.

  18. Can Venezuela's oil sector endure Chavez' ambitions any longer?

    Honkoop, J.

    2009-07-01

    The author describes the decline of Venezuela's oil industry as well as President Chavez' reaction to Venezuela's budgetary crisis. Politicization, falling investment and the obligation to take upon itself a plethora of social spending have left national oil company Petroleos de Venezuela, S.A. unable to produce efficiently and maintain production levels. Falling oil production and lower oil prices have in turn left president Hugo Chavez unable to spread the wealth to Venezuela's poor and he is searching desperately for ways to extract yet more from Venezuela's dysfunctional economy. As funds run out, Venezuela's expensive foreign policy, supporting regional allies, in particular Cuba, and seeking to export anywhere but the United States, proves overly expensive. Venezuela's impoverished masses, still supportive of Chavez during February's elections, may become less so as funds for social programmes run out. For Chavez it is a time for making choices... otherwise the people of Venezuela will choose for him. [nl

    Full Text Available Introducción: las enfermedades cardiovasculares y dentro de estas, el infarto agudo del miocardio han sido el mayor problema de salud y la principal causa de muerte en muchos países del mundo durante varias décadas. Objetivo: determinar la efectividad de la estreptoquinasa recombinante cubana en la morbilidad y mortalidad del infarto agudo del miocardio. Material y método: se realizó una investigación observacional, descriptiva y transversal en los pacientes con diagnóstico de Infarto Agudo del Miocardio, que acudieron al servicio de emergencias del Policlínico Universitario Pedro Borrás, entre septiembre 2009 y agosto 2010. El universo lo integraron 56 pacientes con síndrome coronario agudo con elevación del ST, y la muestra 42 pacientes trombolizados. Las técnicas de procesamiento y análisis fueron la distribución en frecuencias absolutas y relativas y la prueba de ji cuadrado. Resultados: predominaron los pacientes del sexo masculino y edades comprendidas entre 45 y 60 años. Prevaleció la implantación del tratamiento por debajo de las seis horas, siendo tratados un número pequeño de pacientes durante la primera hora, efectiva en todos los casos. Sobresalieron como reacciones adversas la hipotensión arterial y las contracciones auriculares y ventriculares prematuras. Preponderó la desaparición del dolor y regresión de los cambios isquémicos electrocardiográficos como criterios de reperfusión. Conclusiones: el uso de la estreptoquinasa recombinante cubana contribuyó a disminuir la mortalidad en pacientes con infarto agudo al miocardio quedando así demostrado su efectividad.

    Legros, E

    1984-06-01

    Venezuela is Latin America's second greatest oil producer and its dependence on oil production is extreme. Hydrocarbons account for over 90% of its foreign currency earnings, and oil revenue represents the bulk of the state's resources. Statistics on petroleum exploration, production, refining, consumption, and exports are given and related to the status quo and predicted development in Venezuela. The potential contribution of the Orinoco heavy crude oil reservoir is assessed. A decreased independence on oil production as an income market for the country is being sought.

    This paper reports that Venezuela will accept bids under a second round next year from private foreign and domestic companies for production contracts to operate marginal active as well as inactive oil fields. The first such round came earlier this year, involving about 55 other marginal, inactive fields. It resulted in two contractors signed with domestic and foreign companies. It represented the first time since nationalization of the petroleum industry in Venezuela in 1976 that private companies were allowed to produce oil in the country. A public bid tender was expected at presstime last week

  11. Malaria in Sucre State, Venezuela

    Robert H. Zimmerman

    2000-12-01

    Full Text Available The author reviews the malaria research program in Sucre State, Venezuela, taking an ecosystem approach. The goal was to determine which methods could have been introduced at the onset that would have made the study more ecological and interdisciplinary. Neither an ecosystem approach nor integrated disease control were in place at the time of the study. This study began to introduce an ecosystem approach when two contrasting ecosystems in Sucre State were selected for study and vector control methods were implemented based on research results. The need to have a health policy in place with an eco-health approach is crucial to the success of research and control. The review suggests that sustainability is low when not all the stakeholders are involved in the design and implementation of the research and control strategy development. The lack of community involvement makes sustainability doubtful. The author concludes that there were two interdependent challenges for malaria control: development of an ecosystem approach for malaria research and control, and the implementation of an integrated disease control strategy, with malaria as one of the important health issues.O autor faz uma revisão do programa de pesquisa sobre malária no Estado de Sucre, Venezuela, à luz de uma abordagem ecossistêmica. O objetivo era determinar quais métodos poderiam ter sido introduzidos no início do estudo para torná-lo mais ecológico e interdisciplinar. A fase inicial do estudo não incluía uma abordagem ecossistêmica ou controle integrado da doença, que só foram incorporados quando dois ecossistemas contrastantes no Estado de Sucre foram selecionados para pesquisa, junto com um método de controle de vetores com base nos resultados. Uma política de saúde bem-definida com uma abordagem ecossistêmica é crucial para o sucesso de uma estratégia de pesquisa e controle.

    2015-06-01

    Full Text Available As for most batoid species, little is known about the basic biology of the Venezuela round stingray Urotrygon venezuelae (Urotrygonidae. This study presents information about the reproductive biology of the species, including fecundity, embryonic development stage, relationship between maternal size and fecundity, gonadosomatic (GSI and hepatosomatic (HSI indices, sex ratios, maturity size and size at birth. With all this information, a preliminary reproductive cycle is proposed. A total of 269 specimens were caught with beach seine in Salguero beach, Colombian Caribbean Sea, between August 2005 and October 2006. We propose for U. venezuelae a biological cycle with three reproductive peaks: November-December, March-April and August. Size at sexual maturity was calculated in 176 mm (total length for females and 227 mm for males; fecundity ranged between one and six embryos per female. We found that cloacal diameter and liver weight were better predictors for fecundity than total length for U. venezuelae.

  13. Variations of Lipoprotein(a Levels in the Metabolic Syndrome: A Report from the Maracaibo City Metabolic Syndrome Prevalence Study

    Valmore Bermúdez

    2013-01-01

    Full Text Available Background. Lipoprotein(a [Lp(a] is a known risk factor for cardiovascular disease, yet its influence on metabolic syndrome (MS is still controversial. The purpose of this study was to assess the impact generated by this diagnosis in serum Lp(a concentrations. Materials and Methods. A total of 1807 subjects of both genders (55.3% women and 44.7% men belonging to the Maracaibo City Metabolic Syndrome Prevalence Study were evaluated. Results were expressed as Mean ± SD, determining differences through Student’s t-test and One-Way ANOVA test. Multiple logistic regression models were utilized for analyzing factors associated with elevated serum Lp(a levels and MS. Total cholesterol and LDL-C were corrected according to Lp(a-Cholesterol when necessary. Results. No differences were found in Lp(a values between genders; P=0,292. The association between MS and the classification of Lp(a was statistically significant (χ2=28.33; P<0,0001, with greater levels in subjects with this diagnosis. In the univariate analysis, subjects with each of the separate diagnostic criteria showed higher serum Lp(a concentrations, except for hyperglycemia. Conclusions. Lp(a values exhibit important variations regarding MS and each of its components. Impaired fasting glucose appeared as a protecting factor against elevated Lp(a concentrations, whereas its association with LDL-C and hs-CRP suggests a potential pro-inflammatory role.

    Full Text Available RESUMEN: El fracaso renal agudo es un problema frecuente en el paciente oncológico, que plantea limitaciones en el pronóstico y en el planteamiento terapeútico. El desarrollo de registros de pacientes oncológicos con fracaso renal agudo permite analizar el perfil clínico y plantear aspectos a desarrollar desde el punto de vista terapeútico y sobre todo preventivo. El empleo de determinados índices pronósticos como el ISI (Liaño o el de fallo multiorgánico permite evaluar mejor este perfil clínico. En nuestra experiencia el fracaso renal agudo en el paciente oncológico es una complicación frecuente y relacionada con el proceso de base. Mediante este registro de pacientes hemos identificado un perfil clínico de alto riesgo consistente en un paciente con un fallo renal asociado a un proceso infeccioso, con insuficiencia respiratoria, oligúrico y con una puntuación elevada de esos índices pronósticos.

    Full Text Available To assemble Volkswagen cars for the Venezuela market, a large hall has been built, which is fitted with full facilities for its purpose, such as painting and greasing installations, and large parking area for the finished vehicles. The siting of this hall was carefully studied, and such factors as nearness to industrial zones, climate, and ease of access were decisive aspects that were taken into account. The final choice was a site near Morón, in the Carabobo Department, close to the sea. The main constructional item is the roof of the large hall. It is made of a series of hyperbolic-parabolic reinforced concrete thin shells, of rectangular planform, and slightly inclined towards the north, to produce a saw edge profile. Each of these shells is supported by a central column. The hollow spaces along the saw edge profile have been used for ventilation. The enclosing walls consist of trellice material, which also provide ample facility for additional ventilation.Para el montaje de los coches Volkswagen destinados al mercado venezolano, se ha construido una gran nave dotada de todos los servicios necesarios: pintura, engrases, aparcamiento de los vehículos terminados, etc. La elección del lugar más apropiado para la situación de la nave y edificios anexos fue motivo de un detenido estudio, en el que la proximidad a zonas industriales, clima, fácil entrada de materiales procedentes de ultramar y salida para los acabados, fueron los factores decisivos. Definitivamente se eligió un solar en las cercanías de Morón, del departamento de Carabobo, y próximo al mar. Lo más notable es la cubierta de la gran nave, formada por una serie de láminas parabólico-hiperbólicas de hormigón armado, de planta rectangular, inclinadas ligeramente hacia el norte para formar un perfil en diente de sierra.

  4. Occupational Safety and Health in Venezuela.

    Caraballo-Arias, Yohama

    2015-01-01

    Venezuela has pioneered a preventive-focused and comprehensive movement for Occupational Safety and Health (OSH) in Latin America. However, despite being an oil-rich country, it has some of the lowest salaries for their workers and highest levels of hyperinflation, devaluation, crime, and violence of the world. Review the current status and challenges on relevant aspects of OSH in Venezuela. Review of literature and documents from national governments, UN agencies, NGOs, and the Venezuelan government concerning OSH and related topics since 1986. Reformed in 2005, the Organic Law on Prevention, Conditions and Environment (LOPCYMAT) was a fundamental moment of change for OSH. Factors which have impacted OSH the strongest are (i) the creation of the National Institute of Occupational Safety and Health (INPSASEL) and (ii) the socioeconomic crisis Venezuela is going through. Venezuela's laws are innovative and yet non-compliance is enormous. Almost half of the population works in the informal sector. Following the International Labor Office projections, 5 people die per day in Venezuela due to occupational accidents or diseases, making health and safety at work a luxury rather than a right. The quality of life for the average worker has deteriorated, affecting not only health but the overall well-being of all Venezuelans. The political and socio-economic situation has led to a mass exodus of more than 1.6 million highly qualified and talented professionals. Many statistics concerning OSH are not updated and are unreliable regarding occupational accidents and diseases. There is a substantial difference between what is written to protect individual Venezuelans in the workplace and the reality of workplace conditions. Substantial governmental actions are needed in the immediate future to improve occupational safety and health of Venezuelan workers. Copyright © 2015 The Author. Published by Elsevier Inc.

    The combination of seismic, gravimetric and geologic data allowed the construction of a crustal model from the Venezuela Andes. This model is aiming to improve the knowledge from this problematic region. The profile is 160 Km long and it cuts perpendicularly the Andes, across the Soledad, Celoso, Bocono, Virtudes and Gavilan faults. The interpreted reflexions seismic profiles lie both flanks of the Venezuelan Andes. Bouguer anomaly lows do not occurs along the central axis but on the satellite basins located along the Northwestern and Southeastern flanks. The contours tend to group on these flanks reflecting a system related to reverse faults. It was also observed a density contrast separating the Cretaceous-Tertiary from the basement lying at depths greater than 5 Km in the northern Barinas Basin. The same contrast was detected around 10 km along the southern Lake Maracaibo area. The Venezuelan Andes is an asymmetric northern vergent Neogene structure generated under compression, transmitted along basement involved thrusts dipping Southeast. In consequence the tectonic transport is from the Southeast to the Northwest. (author). 7 refs., 5 figs., 2 tabs

  13. National Oil Companies: the view from Venezuela

    Rodriguez, M.

    1994-01-01

    National oil companies were key elements in the initial OPEC strategy and they brought a de-integration of oil industry. These companies have tried to move from crude marketing to product marketing through new investments at home and abroad in order to get higher value added and more secure markets for crude. Low prices bring new challenges. Venezuela's answers are strategic associations, operating contract for marginal fields and profit sharing agreements. (Author)

    Full Text Available The article is devoted to the specificity of Venezuela's energy policy and the features of the evolution of its approaches to solving problems of energy security. Special attention is paid to the projects of Caracas in the energy sector which are aimed at the creating of common energy zone in Latin America. The author has revealed the interaction of internal political processes in Venezuela as the country's leader in the region, with its integration policy, and also identified trends in the further development of energy policy and strategy of Latin American countries. The research of energy resources of Latin America determined that the main factor that works in favor of convergence states within the South American "geopolitical ring" is to ensure energy security. Venezuela is among the richest resources of Latin America. In the research it was determined that Petrosur, Petrocaribe and Petroandina provide the basis for a range of bilateral agreements to promote cooperation, creation ventures based on the state oil companies of these states.

    Full Text Available Las especies del género Callinectes sostienen pesquerías importantes en varias partes del mundo. En el occidente de Venezuela, Callinectes sapidus es capturado con palangre y sostiene una pesquería artesanal importante en el Lago de Maracaibo; mientras que en la Isla de Margarita, Callinectes danae es capturado con nasa en zonas cercanas a lagunas costeras y su pesca está limitada por la oferta y la demanda. Estos recursos son de considerable importancia económica entre los crustáceos comestibles; sin embargo, pocos estudios han sido reportados sobre la dinámica poblacional y potencialidad pesquera en ambientes costeros de Venezuela que contribuyan a la toma de decisiones en la administración pesquera. En este documento se presenta información de los parámetros de crecimiento del cangrejo Callinectes danae Smith, 1869, con el fin de obtener un conocimiento detallado del patrón de crecimiento y lograr estimaciones más precisas sobre el tamaño de la población y su disponibilidad para la explotación. Se analizó una muestra constituida por 3 623 ejemplares capturados con nasa cangrejera por la flota artesanal, entre octubre 2007 y septiembre 2008. Se estableció la relación longitud-peso y se estimaron los parámetros de crecimiento de las curvas en longitud y peso del modelo de von Bertalanffy. La proporción sexual global mostró que no existe diferencia significativa entre machos y hembras (χ2=0.04, p>0.05. Los valores de las pendientes b entre machos y hembras presentaron diferencias significativas (ts=2.75, p<0.05 igualmente los interceptos a (ts=2.44, p<0.05; por lo que se estableció la relación longitud-peso por separado: P=7.48e-5*L2.98 para machos y P=1.21e-4*L2.87 para hembras, evidenciándose un crecimiento alométrico negativo en ambos sexos.

    2012-04-01

    Full Text Available La hiperglucemia con o sin diabetes preexistente es un hallazgo frecuente en pacientes que cursan un síndrome coronario agudo. Estudios previos han demostrado que la hiperglucemia es altamente prevalente y se asocia a un mayor riesgo de muerte y complicaciones hospitalarias. Los mecanismos fisiopatológicos mediante los cuales la hiperglucemia provoca resultados adversos no son claros, y se desconoce si es un marcador de eventos o su causa. Los efectos perjudiciales de la hiperglucemia en el sistema cardiovascular son múltiples, y el control de los niveles de glucosa con insulina parece mejorar el pronóstico en estos pacientes. Se han desarrollado numerosos protocolos para el control de glucemia que demostraron ser seguros y efectivos. En una iniciativa originada en el Consejo de Emergencias de la Sociedad Argentina de Cardiología, se convocó a expertos de nuestro medio con el propósito de debatir estrategias para el control de la glucemia en pacientes que cursan un síndrome coronario agudo. Este documento refleja lo discutido en este evento académico con la intención de resumir los principales aspectos del control de la glucemia y ofrecer recomendaciones generales de tratamiento en la Unidad Coronaria.

    Bidegain Greising, G; Freitez Landaeta, A

    1988-08-01

    Figures of Colombian immigrants in Venezuela in the period 1981-1986 as well as the development of their socio-demographic profile and their integration into the labor market are analyzed by means of ad hoc tables drawn from a Sample Home Survey by the Oficina Central de Estadisticas e Informatica and information from the civil record office. It is estimated that in 1987 there are only half a million Colombians in Venezuela and, contrary to what is generally assumed, not only has the afflux decreased (3/4 of the Colombians entered before 1981), but also a return migration can be observed. Colombian immigration is not homogeneous, but is made up of different groups as far as their professional skills and occupations are concerned. The number of Colombians engaged in household service and those living in rural areas has decreased, but not the number of active farm workers. A greater proportion of Colombians engaged in trade and sales activities is observed, but artisans and skilled labor are still the majority.

    Valero Nereida

    2015-09-01

    Current health conditions of Venezuela, together with the tropical proliferation of different types of Aedes (aegypti and albopictus), suggest the arrival to this country of ZIKA virus (ZIKV). The Pan American Health Organization urges Latin American countries to take measures to prevent the ZIKV entry and advises that these measures must be designed to detect the introduction of ZIKV in an area, track its spread and actively monitor the disease. In Venezuela and other Latin-American countries, where endemicity is high for other arboviruses such as dengue arid chikungunya, health authorities should strengthen their surveillance systems to detect early and timely introduction of ZIKV ap.d refine diagnostic methods to confirm the infection rate; however, the high incidence of cases due those viral agents reflects weakened and poorly timed insensitive monitoring systems, as well as, poor vector control measures, arising the questions: will this arbovirus pop in our country, will it set as the other as edemicepidemic and lead to alter their clinical behavior and severity of the disease?

  1. [Three phases of homicidal violence in Venezuela].

    Briceño-León, Roberto

    2012-12-01

    Venezuela was considered one of the least violent countries in Latin America, however by 2010 it was among the countries with the highest homicide rate. This article analyzes the evolution of homicides in Venezuela between 1985 and 2010 and proposes the existence of three stages which correspond to trends in social and political institutions of the country. The first from 1985 to 1993, characterized by the looting of 1989 and the coups d'état of 1992, when for the first time the homicide rate rose from 8 to 20. The second phase from 1994 to 1998 was a recovery period of the institutional and political stability when the homicide rate remained constant at around 20. The third phase began in 1999 with the H Chavez government and the institutional destruction that comes with the Bolivarian revolution and caused an increase in the rate of 20 to 57 homicides per 100 thousand inhabitants. This article argues that the explanation for the changes in the phases is to be found in the transformation of social and political institutions.

São revisados modelos de serviços hospitalares para admissão e manuseio de casos agudos em idosos, com ênfase na discussão sobre o papel e o posicionamento da medicina geriátrica (incluindo sua interface com especialidades e com a clínica médica no âmbito da atenção hospitalar. Foi realizada pesquisa na base de dados Medline (1989-1999, bem como nos principais livros-texto de geriatria e de gerontologia, buscando identificar descrições de serviços hospitalares para cuidado agudo de pacientes idosos. As características dos modelos identificados foram compiladas e descritas à luz de sua adequação à realidade dos serviços de saúde no Brasil. Exemplos de intervenções em geriatria, com efetividade demonstrada através de revisões sistemáticas, foram também citadas. Os modelos mais freqüentemente relatados foram cuidado prolongado, tradicional, baseado na idade cronológica, não especializado e integrado. Adaptações e variantes de alguns desses modelos foram freqüentemente relatadas, assim como seu impacto potencial na efetividade do cuidado geriátrico. Evidências sobre o melhor modelo a seguir não foram identificadas, mas aqueles modelos favorecendo a integração da geriatria com a clínica geral pareceram mais adequados à nossa realidade. Ressalta a necessidade de reestruturação de serviços de saúde para responder às novas demandas que surgem com o envelhecimento da população, bem como do delineamento de serviços hospitalares para casos agudos, importantes para a efetividade do cuidado geriátrico e que devem ser objeto de maior debate e pesquisa no Brasil.

    This study presents the results of an integrated reservoir study of the Eocene B-Inferior/VLG-3659, Area 7, Ceuta filed. This field located in the Maracaibo Lake in the western side of Venezuela. The objective was to evaluating the feasibility to implement a secondary recovery project by means of water flooding. Core information was used for this study (194 ft), PVT analysis, RFI, build-up and statistic`s pressure analysis, modem logs and production history data. Using geostatistical techniques (Kriging) it was defined a low uncertainty geological model that was validated by means of a black oil simulator (Eclipse). The results showed a good comparison of historical pressure of the reservoir against those obtained from the model, without the need of {open_quotes}history matching{close_quotes}. It means without modifying neither the initial rock properties nor reservoir fluids. The results of this study recommended drilling in two new locations, also the reactivation of four producing wells and water flooding under peripherical array by means of four injection wells, with the recovery of an additional 30.2 MMSTB. The economical evaluation shows an internal return rate of 31.4%.

    Full Text Available La presente investigación muestra los patrones geográficos de las hospitalizaciones por infarto agudo al miocardio en el seguro público de salud de Costa Rica en el trienio 2010-2012. Para el análisis geográfico por área de salud se utiliza un modelo bayesiano jerárquico espacial. Se estiman razones estandarizadas suavizadas y, como medida de precisión, la probabilidad de que cada área de salud registre un riesgo de hospitalización estadísticamente diferente al promedio nacional. En la determinación de presencia de autocorrelación espacial se utiliza el indicador de la I de Moran. La amplitud entre las variaciones observadas se estima mediante la razón interpercentil (percentil 95/percentil 5 y el coeficiente de variación. La tasa bruta de hospitalizaciones es de 5,8 por 10 mil habitantes en hombres y 2,6 / 10 mil en mujeres. Se registra un rango de variación de más de dos veces en las hospitalizaciones entre las áreas con mayores y menores egresos. Se presenta un patrón de bajas tasas de hospitalizaciones por infarto agudo al miocardio en áreas de salud fuera del Área Metropolitana, donde se encuentran los hospitales nacionales de mayor complejidad. Este elemento podría estar asociado a dificultades en el acceso de los servicios de hospitalización.

  13. Nostalgic Venezuela. Reelection, rupture and revolution

    Ángel Dámaso Luis León

    2017-09-01

    Full Text Available The Republic of Venezuela was an oasis in Latin America, a stable, democratic and prosperous country for several decades until the coming of the 1980s’ crisis. The new context and the erosion of traditional actors forced profound political changes. The crisis, the adjustments made during the 1990s and the population’s hopes of one day returning to the path of prosperity generated increasingly radical policy responses. This article seeks to analyse the political responses of the Venezuelan people to the challenges posed by their new socioeconomic reality and how these connect with visions derived from past experience and the approach to the roles of state and leader. It also explores the frustration caused by failure to meet their expectations, leading to the election of increasingly radical options.

    Each day cities inhabitants are exposed to visual pollution. This work assess the environmental impact caused by visual pollution in public spaces, using as a case of study a mixed-use neighborhood in San Cristobal, the capital of Tachira state, Venezuela. Such assessment was made using a qualitative approach, where special emphasis was paid to the perception of these impacts by a purposive sample of users of this area. The compilation and analysis of information reveal the main visual pollutants existing in these public spaces where, in addition to outdoor advertising, overhead wires, rubbish, graffiti, vacant land, among others, cars and outdoor kiosks. Neighborhood users are sensitive to the presence of visual pollutants, which affects them physically and psychologically, as well as for the visual quality of their environment. Such signs were used to guide a qualitative appraisal of environmental impacts generated by these circumstances and to propose policies to mitigate them.

Durante esta coyuntura, la nueva actividad minera actuó como elemento dinamizador del centro mercantil lacustre debido al incremento de los negocios de criollos y extranjeros que lograron reactivar el comercio de importación de bienes y servicios al acentuarse la demanda local. El método histórico permitió la identificación de los factores que intervinieron en la reactivación económica y la explicación del proceso de reacomodo que se dio en el circuito, a través de la información que aportaron las diversas fuentes analizadas.The article pretends to approach the historical process of the Maracaibo's agricultural exporting circuit during the first decades of XX century and its strengthening generated by the incorporation of the petroleum exploitation that stirred the Zulia's trade debilitated in the last stage of the nineties. During this conjuncture, the new mining activity acted as a revitalizing and of integration element of the lacustrine mercantile center due to the increase of the business of creoles and foreigners who managed to reactivate the trade of import on having invested the capitals in goods and services with local, regional and international demand. In the investigation it was used the historical method that allowed the identification of the factors that intervened in the process of rearrangement that was given in the circuit across the information that the diverse analyzed sources contributed.

    Full Text Available Los debates sobre la democracia en la Venezuela de hoy carecen de una definición común sobre el tema, sobre cómo estudiarlo, e incluso respecto a qué es democracia. El régimen ha sido descrito de muchas formas: democracia participativa, híbrido, mixto, personalista, populista, iliberal, autoritarismo competitivo. El objetivo de este trabajo es determinar el nivel de calidad de la democracia en Venezuela, en el marco de una concepción procedimental de la democracia. La evaluación empírica de cinco dimensiones de calidad de la democracia (decisión electoral, participación, respuesta a la voluntad popular, rendición de cuentas y soberanía revela un nivel bajo en conjunto, con escasa variación entre 2005 y 2010. Los escenarios posibles luego de las elecciones de 2012 incluyen: reforzamiento de las tendencias autoritarias, militarización abierta, liberalización política con fortalecimiento institucional, o volatilidad duradera con conflicto polarizado y debilidad institucional. La salud del presidente Chávez afectará estos escenarios, dado su carácter de factor central unificador de su movimiento y del régimen.Discussions of democracy in contemporary Venezuela lack a settled definition of the subject, how to study it, or indeed of what counts as «democracy» in the first place. The regime has been described as everything from participatory democracy, hybrid, mixed, and personalist to populist, illiberal, or no longer democratic but rather competitive authoritarian. The goal of this article is to measure the quality of democracy in Venezuela, within the terms of a procedural concept of democracy as detailed in our earlier work. Empirical measurement of the quality of democracy on five dimensions (electoral choice, participation, responsiveness, accountability, sovereignty reveals a low level overall and deep institutional weakness under a personalist leadership, with little change from 2005 to 2010.

    Full Text Available JUSTIFICATIVA E OBJETIVOS: A ocorrência de infarto agudo do miocárdio (IAM durante a gravidez é rara. Os autores descrevem o caso de IAM numa grávida de 31 semanas e a importância da existência de uma equipe multidisciplinar para sua abordagem. RELATO DO CASO: Grávida de 31 semanas, com antecedentes de tabagismo, alcoolismo e hipertensão, internada após um episódio de síncope. Na admissão, encontrava-se consciente e assintomática, embora hipotensa. O eletrocardiograma evidenciou marcada elevação do segmento ST em DI, AVL, V1-V6. Pesquisa de enzimas cardíacas foi positiva. O ecocardiograma transtorácico demonstrou redução da contratilidade ventricular esquerda e septal e uma fração de ejeção de 30%. A angiografia revelou oclusão proximal da artéria descendente anterior. Por insucesso da angioplastia por balão, foi colocado um stent metálico. A paciente iniciou terapêutica com b-bloqueadores, aspirina e clopidogrel. Em relação ao parto, optou-se por realizar cesariana eletiva, quatro semanas após o IAM. Suspendeu-se o clopidogrel sete dias antes do parto. A função cardíaca pré-operatória foi otimizada com infusão de levosimendana iniciada no dia anterior. A cesariana decorreu sob bloqueio peridural. O período intraoperatório decorreu sem complicações, à exceção de moderada hipotensão facilmente corrigida com fenilefrina. O índice de Apgar do recém-nascido foi de 9/10. CONCLUSÕES: Este é um dos poucos casos de infarto agudo do miocárdio e angioplastia descritos durante a gravidez. Os autores discutem as decisões tomadas pela equipe multidisciplinar, constituída por anestesiologistas, obstetras, cardiologistas e neonatologistas, notadamente no que se refere à dupla antiagregação plaquetária, ao tipo de parto e à anestesia.

Se caracteriza por síntomas de comienzo agudo y curso fluctuante con inatención, pensamiento desorganizado, y con distintos niveles de alteración de la conciencia.En la bibliografía consultada, el SCA como manifestación de un síndrome de abstinencia aguda nicotínica fue descripto en solo ocho casos. Presentamos el caso de un tabaquista grave que, internado por una reagudización de su enfermedad pulmonar obstructiva crónica (EPOC, presentó un cuadro de SCA al tercer día de abstinencia tabacal, cediendo los síntomas tras la administración de un parche de nicotina. Lo descripto sugiere que en pacientes internados que presentan SCA y agitación, con fuertes antecedentes de tabaquismo, un simple ensayo con un parche de nicotina puede ofrecer en pocas horas una notable respuesta terapéutica y a su vez un test confirmatorio. El reconocimiento del SCA como forma de presentación de la abstinencia nicotínica permitirá identificar casos habitualmente complejos en los que se podrá implementar una sencilla y eficaz alternativa terapéutica.Delirium or acute confusional state among hospitalized patients is a frequent and serious problem. It is characterized by acute onset symptoms, fluctuating course, impaired attention, unorganized thinking, and altered level of conciousness. Delirium, as a manifestation of acute nicotine withdrawal syndrome has been reported in the reviewed literature only in eight cases. We report the case of a heavy smoker admitted because of a reagudization of his chronic obstructive pulmonary disease. At the third day of nicotine abstinence, he developed delirium with a rapid improvement of his symptoms after treatment with a transdermal nicotine patch. This description suggests that in hospitalized heavy smokers who develop delirium with agitation, a simple trial with a nicotine patch can offer a dramatic

    Onchocerciasis is caused by Onchocerca volvulus and transmitted by Simulium species (black flies). In the Americas, the infection has been previously described in 13 discrete regional foci distributed among six countries (Brazil, Colombia, Ecuador, Guatemala, Mexico and Venezuela) where more than 370,000 people are currently considered at risk. Since 2001, disease control in Venezuela has relied on the mass drug administration to the at-risk communities. This report provides empirical evidence of interruption of Onchocerca volvulus transmission by Simulium metallicum in 510 endemic communities from two Northern foci of Venezuela, after 10-12 years of 6-monthly Mectizan (ivermectin) treatment to all the eligible residents. In-depth entomologic and epidemiologic surveys were serially conducted from 2001-2012 in selected (sentinel and extra-sentinel) communities from the North-central (NC) and North-east (NE) onchocerciasis foci of Venezuela in order to monitor the impact of ivermectin treatment. From 2007-2009, entomological indicators in both foci confirmed that 0 out of 112,637 S. metallicum females examined by PCR contained L3 infection in insect heads. The upper bound of the 95% confidence intervals of the infective rate of the vector reached values below 1% by 2009 (NC) and 2012 (NE). Additionally, after 14 (NC) and 22 (NE) rounds of treatment, the seasonal transmission potential (±UL CIs) of S. metallicum was under the critical threshold of 20 L3 per person per season.

    Venezuela had the highest number of human malaria cases in Latin American before 1936. During 1891–1920,malaria was endemic to >600,000 km2 of this country; malaria death rates led to major population decreases during 1891–1920. No pathogen, including the influenza virus that caused the 1918 pandemic, caused more deaths than malaria during 1905–1945. Early reports of malaria eradication in Venezuela helped spark the world's interest in global eradication. We describe early approaches to malaria epidemiology in Venezuela and how this country developed an efficient control program and an approach to eradication.Arnoldo Gabaldón was a key policy maker during this development process. He directed malaria control in Venezuela from the late 1930s to the end of the 1970s and contributed to malaria program planning of the World Health Organization.We discuss how his efforts helped reduce the incidence of malaria in Venezuela and how his approach diverged from World Health Organization guidelines.

    Full Text Available Este artículo analiza quién toma las decisiones en los hogares y los factores que afectan la decisión. Esta investigación se condujo en Venezuela, donde se preguntó a las mujeres sobre las decisiones de los hogares en cuatro áreas. Los resultados indican que la mayoría de los hogares toman decisiones conjuntamente. Excluyendo esta categoría, la mayoría de las mujeres toman decisiones concernientes a la compra de bienes y la educación de los hijos, mientras que los hombres dominan las decisiones acerca de las finanzas del hogar y el cambio de residencia. También se encontró que la mayoría de las parejas que trabajan comparten los gastos del hogar. Además, se identifican factores que afectan el poder de decisión de las mujeres como la participación femenina en el mercado laboral y la edad, no obstante, el nivel de educación no afecta su poder decisión.

  17. [Increasing difficulties for scientific publication in Venezuela].

    Ryder, Elena

    2014-03-01

    A very important increase in the costs of the edition of scientific journals has taken place in Venezuela, due to difficulties in obtaining imported free acid paper and other materials used for handling documents. Like other journals, Investigaci6n Clinica has been considering switching completely to a digital publication format; however there are several reasons that prevent us to doing it at this time: the journal is distributed in printed form to many national institutions, which do not have immediate access to digital information. In addition, there exists a commitment of shipment of printed issues for some international indices and in exchange with other national and foreign journals, whose printed format we receive. Another important aspect is that our University maintains a weak technological platform that makes difficult the immediacy required for the interchange with authors and consulted referees of received papers; and there is a latent danger of limitations in the use of digital technologies, due to current national politic problems. Consequently, we need to continue with the printed format, but must reduce the amount of printed issues, so as not to limit the number of papers published in each edition. Nevertheless, there is an ever increasing number of contributions from foreign researches and Investigaci6n Clinica has been recently included in two new international indices, the SEIIC from Argentina and the Infobase Index from India, reasons that obligate us to maintain our levels of excellence and commitment to our authors and readers.

  18. Social Change and Health Policy in Venezuela

    Nuramy J. Gutiérrez

    2008-07-01

    Full Text Available This work reviews social changes occurring in Venezuela during the last two decades, examining how they led to the development of a new health policy. Initially, the political context of the nineties is examined; this was a time when the neoliberal politics of the 1980’s had a demonstrable impact on the living conditions and health status of the population. By 1999 social and political events led to a new Constitution which provided the juridical and legal framework for a new health policy. The conceptualization of health and the model of health care which arose from the constitutional process are considered, as well as the reaction of the dominant economic and political sectors to the new policies imposed by constitutional mandate. The emergence of Barrio Adentro and other social missions is analyzed as an essential factor in the initiation of structural changes within the country and its health institutions. The Barrio Adentro program is described in detail, along with key steps in the development of the Venezuelan National Public Health System. Finally, the impact of these new health policies on the quality of life of the Venezuelan population is delineated.

    In the last years opioids have become of great importance in the relief of postoperative and other forms of acute pain. Reasons for this trend have been the availability of agonist opioids like phentanyl. sulphentanyl and alphentanyl and the results of research on the physlology. The pharmacology and the chemistry of drug receptors and neurotransmitters. The studies on chemicals other than opioids that contribute to pain relief when administered through different ways. specially the spinal. Have also influenced such a trend.

    En los últimos años los opiáceos han adquirido gran importancia en el alivio del dolor agudo especialmente del tipo postoperatorio. Una de las razones ha sido la disponibilidad de morfínicos agonistas como el fentanil, el sufentanil y el alfentanil; otra es la investigación de la fisiología, la farmacología y la química de los receptores y los neurotransmisores como de sustancias diferentes a los opláceos, aplicadas por diferentes vías en especial la espinal, que coadyuvan al alivio del dolor.

  2. Assessing Whether Oil Dependency in Venezuela Contributes to National Instability

    Adam Kott

    2012-08-01

    Full Text Available The focus of this article is on what role, if any, oil has on Venezuela's instability. When trying to explain why a resource-rich country experiences slow or negative growth, experts often point to the resource curse. The following pages explore the traditional theory behind the resource curse as well as alternative perspectives to this theory such as ownership structure and the correlation between oil prices and democracy. This article also explores the various forms of instability within Venezuela and their causes. Finally, the article looks at President Hugo Chavez's political and economic policies as well as the stagnation of the state oil company, Petroleos de Venezuela (PDVSA. This article dispels the myth that the resource curse is the source of destabilization in many resource dependent countries. Rather than a cause of instability, this phenomenon is a symptom of a much larger problem that is largely structural.

    Full Text Available This paper suggests a variation of the IMO index (Okun's Misery Index, adapting it to markets with these characteristics, adding the ESI level (Employment in the Informal Sector to the unemployment level. This research compares the evolution of several standard misery indexes in several zones during the last decades, with emphasis on the case of Venezuela, for which the new proposed index is also estimated. Results show improvement in the well-being of groups of countries under study, compared to the deterioration of the indicator in Venezuela. In general terms, the IMO is controlled by unemployment, except in Venezuela. However, preponderance of inflation over unemployment in this country seems to occur by the underestimate that the unemployment rate has on the Venezuelan labor market situation.

    This paper has been presented at DEGIT-X held in México 2005.-- Revised: 2008-08. Venezuela's growth experience over the past fifty years is characterized by a high economic growth rate from 1950 to 1970 and a low economic growth rate in the last thirty years. Although Venezuela is an oil abundant economy, this growth experience is largely accounted for by the evolution of its real non-oil GDP. We use growth accounting to quantify the extent to which the growth experience in non-oil sector...

  9. Events affecting gold exploration in Venezuela since 1999

    Wilburn, David R.

    2014-01-01

    The structure of the gold mining industry in Venezuela has changed significantly since 1999 as a result of Government policy changes and industry response to these changes. This report documents the policy decisions that have affected the mining industry, discusses the response of the industry on a site by site basis, and suggests possible effects of these changes on the global economy. For the short term, at least, it appears that these changes have made Venezuela a more difficult place to invest for U.S. and Canadian companies, while investment by Chinese entities has been encouraged.

  10. The Bocono Fault Zone, Western Venezuela

    Schubert, C. (I.V.I.C., Caracas (Venezuela)); Estevez, R. (Universidad de los Andes, Merida (Venezuela)); Henneberg, H.G. (Universidad del Zulia, Maracaibo (Venezuela))

    1993-02-01

    The Bocono Fault Zone, the western part of the Bocono Moron-El Pilar Fault System of the southern Caribbean plate boundary, consists of aligned valleys, linear depressions, pull-apart basins and other morphological features, which extend for about 500 km in a N45[degrees]E direction, between the Tachira depression (Venezuela-Colombia border) and the Caribbean Sea. It crosses obliquely the Cordillera de Merida and cuts across the Caribbean Mountains, two different geologic provinces of Late Tertiary-Quaternary and Late Cretaceous-Early Tertiary age, respectively. Therefore, the maximum age that can be assigned to the Bocono Fault Zone is Late Tertiary (probably Pliocene). A total maximum right-lateral offset rate of 3.3 mm/a. The age of the sedimentary fill o[approximately] the La Gonzalez pull-apart basin suggests that the 7-9 km right-lateral offset necessary to produce it took place in Middle to Late Pleistocene time. The majority of seismic events are well aligned with the main fault trace; minor events are distributed in a belt several kilometers wide. Focal depth is typically 15 km and focal mechanisms indicate an average east-west compression across the zone. Return periods of 135-460 a (Richter M = 8), 45-70 a (M = 7), and 7-15 a (M = 6) have been calculated. Geodetic studies of several sites along the zone indicate compressive and right-lateral components; at Mucubaji the rate of right-lateral displacement observed is about 1 mm every 5 months (15 a of measurements).

  11. pobres y nuevas coaliciones en Venezuela

    Charles L. Briggs

    2007-01-01

    Full Text Available En Venezuela, los gobiernos locales junto con el gobierno nacional, crearon un sistema nacional de salud paralelo, Misión Barrio Adentro (MBA, ubicando a unos 33.000 profesionales de la salud, inicialmente cubanos, en vecindarios de bajos ingresos. A través de la etnografía y entrevistas, se concluye que MBA proporcionó acceso a la atención médica y logró obtener apoyo popular a consecuencia de: movimientos sociales de los pobres; cooperación entre trabajadores comunitarios, residentes, profesionales de salud y funcionarios públicos; la integración de la atención médica con programas sociales y económicos; la ubicación de médicos como residentes en barrios pobres; interacciones positivas y equitativas médico-paciente; el papel clave de los Comités de Salud; y el impacto de la hostilidad de la prensa, un segmento grande de los médicos venezolanos y la oposición en transformar a la salud en un tema político esencial. Todo esto nos sugiere que el Estado puede confrontar las inequidades de salud cuando se unen perspectivas teóricas de la medicina social y la epidemiología crítica con los saberes populares dentro de las comunidades afectadas. Estructuras institucionales flexibles, no burocráticas y creativas aumentan la efectividad de las intervenciones.

    It is study the feasibility of development of the alternative energies, AE, in Venezuela based on its potential of exploitation, the analysis of its energetic system, and the attitude of the State before the AE. The results indicate that the country has a high potential of AE, that the hidroenergy in great scale is the unique one with an important participation in the energy system, and that the solar energy and the eolic are those of greater possibility of development. However, an assembly of factors impede the development in firm of the AE, fundamentally related to its historic condition of producer and consumer of fuel fossil in great scale at low cost. It is concluded that only with a change of attitude of the State and the concourse of all the actors involved in the sector, the {sup c}lean energies{sup w}ould be able to have an important weight in the national energetic balance.

    Full Text Available Objetivos: Determinar la frecuencia de secuela renal después del evento agudo de Síndrome Urémico Hemolítico (SUH en niños y los factores asociados a la presencia de secuelas. Material y métodos: Estudio descriptivo y retrospectivo. Se revisaron las historias clínicas de los pacientes con SUH en el HNCH de 1997 al 2012, y se registraron datos de características clínicas, hallazgos de laboratorio y parámetros de función renal al ingreso, al alta y a los seis meses después del alta. En los casos que no contaban con control a los 6 meses, se intentó contactar a los pacientes para tomar nuevos controles. Resultados: Siete de 12 pacientes presentaron disminución en la tasa de filtración glomerular (TFG o proteinuria o hipertensión a los 6 meses o más después del episodio agudo, con un promedio de 30,75 meses de seguimiento. Tanto en los pacientes con secuelas como con recuperación renal se encontró una distribución similar de los factores asociados a secuelas como hipertensión al alta, proteinuria al alta, necesidad de diálisis, oligoanuria, leucocitosis > 20 000 cel/mm3 y síntomas neurológicos. Sin embargo algunas variables como oligoanuria y necesidad de diálisis se encontraron a niveles por debajo de los descritos en la literatura. Conclusiones: Es claro que existen pacientes con secuelas renales luego del episodio agudo de SUH que además presentan varios factores predictores de secuelas descritos en la literatura.

Frente al nivel de adherencia al tratamiento, predominó la adherencia total (54 %, adherencia parcial (45%; en cuanto a la calidad de vida relacionada con la salud, el 27 % tuvo un bajo nivel; respecto a la correlación de Spearman, se estableció un coeficiente de -0,315 con una significancia de p=0,00, donde el número negativo es reflejo de la naturaleza de las escalas con las que fueron medidas las variables, por lo que la correlación es positiva, significativa, pero numéricamente modesta. Conclusión: la asociación entre adherencia al tratamiento y calidad de vida relacionada con la salud evidencia en una correlación estadísticamente significativa, pero catalogada como modesta, siendo estos resultados coherentes con la multidimensionalidad de los fenómenos.

    Full Text Available Fundamento: el tratamiento trombolítico practicado a menos de dos horas, tras el inicio del infarto tiene resultados similares a la reperfusión mecánica. Objetivo: describir aspectos relevantes de la terapia trombolítica en pacientes con infarto agudo de miocardio con elevación del segmento ST en Cienfuegos. Métodos: estudio descriptivo, prospectivo, en 225 pacientes egresados (vivos y fallecidos desde el 1o de abril de 2012 al 31 marzo de 2013, de la Unidad de Cuidados Integrales del Corazón y la Unidad de Cuidados Intensivos Polivalentes, del Hospital Dr. Gustavo Aldereguía Lima. Las variables estudiadas se obtuvieron de la revisión de las historias clínicas e incluyeron: variables demográficas y clínicas, tiempos de demora, sitio, motivo de exclusión y nivel de prioridad para la trombolisis. Resultados: la media de edad superó los 60 años. Predominaron los hombres, hipertensos y de alto riesgo según la escala GRACE. El 29,7 % de los pacientes no recibió terapia trombolítica, debido mayormente al factor tiempo y la mayoría (82,3 % se trató en el Hospital. Las medianas de los tiempos de demora: síntomas-puerta, puerta-droga y síntomas-droga fueron 90, 35 y 140 minutos respectivamente. Conclusiones: la trombolisis extrahospitalaria acorta el tiempo total de isquemia, pero pocos pacientes se beneficiaron de ella. Los retrasos para la terapia trombolítica en Cienfuegos continúan por encima de los estándares requeridos.

    2000-09-01

    Full Text Available Se realizó una revisión acerca de la formación de radicales libres de oxígeno en el organismo, así como el aumento exagerado de su génesis durante la exposición a altas concentraciones de oxígeno y en el desarrollo de la explosión respiratoria que acompaña la fagocitosis. Se analiza además la formación de estos radicales en el pulmón durante la evolución del distress respiratorio agudo. Se abordó, posteriormente, el uso actual, sobre todo en el ámbito internacional, de los antioxidantes y bloqueadores de la lipoperoxidación para disminuir los efectos adversos de los radicales libres. A pesar de estas nuevas medidas, se corrobora que la disminución experimentada en la mortalidad por esta entidad, obedece a la optimización de los cuidados respiratorios, en especial la ventilación mecánica.The formation of free oxygen radicals in the body and the excessive increase of its genesis during exposure to high concentrations of oxygen and in the development of respiratory burst accompanying phagocytosis were reviewed. Also the formation of these radicals in lung during acute respiratory distress was analyzed. Similarly, the present use at the international level of antioxidants and lipoperoxidation blockers to diminish adverse effects of free radicals are addressed in this paper. In spite of these new measures, it was confirmed that the reduction of mortality rate from this disease was due to the improvement of respiratory care particularly the mechanical ventilation.

    2013-06-01

    The data of accidents caused by snakebites in Venezuela, registered at the morbidity statistics of the Direction of Epidemiology and Strategic Analysis of the Ministry of Health and Social Development were analyzed. During the years of 1996-2004, 53,792 snakebites were registered in Venezuela (5,976 cases average per year), with a higher incidence during the year 2004 (7,486 incidents). Zulia reported the highest frequency of all the states (5,975 cases); meanwhile the Midwestern region, constituted by Lara, Portuguesa, Falc6n and Yaracuy states, had a higher morbidity for snake bites. The highest incidence, distributed per states was registered in Cojedes, during the year 2001, with 228.72 cases per 100,000 inhabitants. When it was determined by regions, the highest incidence occurred during the year 2004 at los Llanos with 63.81 per 100,000 inhabitants. The median of the incidence rate for Venezuela during the period was of 21.46 accidents per 100,000 inhabitants. The classification of the endemic areas for ophidism, according to the percentiles 23, 50, 75 and 90, organized the country in: (a) states and regions of very high endemicity, (b) high endemicity, (c) middle, (d) low and (e) very low endemicity. These epidemiological data indicated that the accidents caused by snakes constitute a collective health problem in Venezuela.

  16. CYP2D6 variability in populations from Venezuela.

    Moreno, Nancy; Flores-Angulo, Carlos; Villegas, Cecilia; Mora, Yuselin

    2016-12-01

    CYP2D6 is an important cytochrome P450 enzyme that plays an important role in the metabolism of about 25% of currently prescribed drugs. The presence of polymorphisms in the CYP2D6 gene may modulate enzyme level and activity, thereby affecting individual responses to pharmacological treatments. The most prevalent diseases in the admixed population from Venezuela are cardiovascular and cancer, whereas viral, bacterial and parasitic diseases, particularly malaria, are prevalent in Amerindian populations; in the treatment of these diseases, several drugs that are metabolized by CYP2D6 are used. In this work, we reviewed the data on CYP2D6 variability and predicted metabolizer phenotypes, in healthy volunteers of two admixed and five Amerindian populations from Venezuela. The Venezuelan population is very heterogeneous as a result of the genetic admixture of three major ethnical components: Europeans, Africans and Amerindians. There are noticeable inter-regional and inter-population differences in the process of mixing of this population. Hitherto, there are few published studies in Venezuela on CYP2D6; therefore, it is necessary to increase research in this regard, in particular to develop studies with a larger sample size. There is a considerable amount of work remaining before CYP2D6 is integrated into clinical practice in Venezuela.

  1. Diversity of avian haemosporidians in arid zones of northern Venezuela.

    Belo, Nayara O; Rodríguez-Ferraro, Adriana; Braga, Erika M; Ricklefs, Robert E

    2012-07-01

    Arid zones of northern Venezuela are represented by isolated areas, important from an ornithological and ecological perspective due to the occurrence of restricted-range species of birds. We analysed the prevalence and molecular diversity of haemosporidian parasites of wild birds in this region by screening 527 individuals (11 families and 20 species) for parasite mitochondrial DNA. The overall prevalence of parasites was 41%, representing 17 mitochondrial lineages: 7 of Plasmodium and 10 of Haemoproteus. Two parasite lineages occurred in both the eastern and western regions infecting a single host species, Mimus gilvus. These lineages are also present throughout northern and central Venezuela in a variety of arid and mesic habitats. Some lineages found in this study in northern Venezuela have also been observed in different localities in the Americas, including the West Indies. In spite of the widespread distributions of some of the parasite lineages found in northern Venezuela, several, including some that are relatively common (e.g. Ven05 and Ven06), have not been reported from elsewhere. Additional studies are needed to characterize the host and geographical distribution of avian malaria parasite lineages, which will provide a better understanding of the influence of landscape, vector abundance and diversity, and host identity on haemosporidian parasite diversity and prevalence.

  4. Poverty rates in Venezuela: getting the numbers right.

    Weisbrot, Mark; Sandoval, Luis; Rosnick, David

    2006-01-01

    This article looks at household and individual poverty rates in Venezuela over the past seven years. For more than a year, the statement that poverty in Venezuela has increased under the government of President Hugo Chávez has appeared in scores of major newspapers, on major television and radio programs, and even in publications devoted to foreign policy. There are no data to support such statements, and in fact the available data show a decline in poverty for both individuals and households over the seven-year period: the percentage of people in poverty declined from 50 percent in the first quarter of 1999 to 43.7 percent in 2005. Further, there is no evidence to suggest any change in the methodology for measuring poverty during this period, as has been alleged in a number of reports. The article also examines briefly the impact of significant changes in non-cash benefits such as free health care, which are not taken into account in the measured poverty rate, on poor people in Venezuela. Finally, the authors look at how the mistakes in reporting on Venezuela's poverty rate were made; an appendix gives examples of mistakes in major media and foreign policy publications.

  6. More oil sand cooperation between Canada and Venezuela

    1977-07-01

    Venezuela has pioneered the production of heavy oil, according to Dr. A. Guzman-Reyes, director general of hydrocarbons for the Venezuelan government. The first heavy oil production began in Venezuela 60 yr ago and the oil industry has steadily improved methods of producing and handling heavy oil. The country's producing fields are capable of yielding almost one million barrels of heavy oil daily, although actual production, largely because of market limitations, is about 650,000 bpd. Canada's daily heavy oil production, including the 60,000 bbl of synthetic crude produced daily by the Great Canadian Oil Sands plant, is about 200,000 bbl. Dr. Guzman-Reyes stated that Venezuela intends to rapidly develop heavy oil production and upgrade facilities to maintain its export markets. The national oil company, Petroleos de Venezuela, plans to invest 4 times the amount spent on oil development over the last 60 yr during the next 10 yr, a total of $3 billion by 1980.

In this sense, this article aims to develop a mapping of micro and small enterprises in the industrial sector in the cities of Agudo and Silveira Martins – Rio Grande do Sul (RS. For this, we used a descriptive research on the purposes and literature as to the means being prepared a questionnaire for collecting data from the sample studied. As results obtained ten micro companies and three small businesses were found in Agudo – RS, and the main industries are the timber industry and the manufacture of bakery products, influenced 65.5% of the employees of micro and small companies analyzed in the municipality. Already in Silveira Martins – RS were found seven micro and small enterprises, where six are classified as micro company and only one as small business. It was found also that the main industrial branch is the timber sector (six companies, in which 96% of employees work in any activity related to wood processing.

  17. EJERCICIO Y LA DETECCION DEL MAL AGUDO DE MONTAÑA GRAVE

    Garófoli, Adrián; Montoya, Paola; Elías, Carlos; Benzo, Roberto

    2012-01-01

    El Mal Agudo de Montaña (MAM) es un conjunto de síntomas inespecíficos padecidos por sujetos que ascienden rápidamente desde baja a alta altura sin adecuada aclimatación. Usualmente es autolimitado, pero las formas graves (edema pulmonar y cerebral) pueden causar la muerte. La hipoxemia exagerada en reposo está relacionada con el desarrollo de MAM pero su valor predictivo es limitado. Dado que el ejercicio en altura se acompaña de mayor hipoxemia y síntomas, postulamos el valor predictivo de un simple test de ejercicio para pronosticar MAM grave. Se estudió el valor predictivo de la saturación de oxígeno en reposo y ejercicio submáximo a 2 700m y 4 300m en 63 sujetos que ascendían al cerro Aconcagua (6 962m). Se consideró desaturación de oxígeno con ejercicio a una disminución >=5% respecto al reposo. Se utilizó la escala de Lake-Louise para establecer la presencia de MAM grave. 6 sujetos presentaron MAM grave (9.5%) y requirieron evacuación. La saturación de oxígeno en reposo a 2 700m no fue significativa para clasificar sujetos que luego desarrollaron MAM grave. Por el contrario, la asociación de desaturación durante el ejercicio a 2 700m más la saturación inapropiada en reposo a 4 300m fue significativa para clasificar a los sujetos que desarrollaron MAM grave con un valor predictivo positivo de 80% y un valor predictivo negativo del 97%. Nuestros resultados son relevantes para el montañismo y sugieren la adición de un simple test de ejercicio en la predicción del MAM grave. PMID:20228017

    Full Text Available Con muy diversas investigaciones se han demostrado los efectos agudos del ejercicio físico en los procesos cognitivos (memoria, inteligencia, tiempo de reacción, creatividad, etc. según la edad. Sin embargo, gran cantidad de variables se ven involucradas en los diferentes tratamientos. Es, por esto, que se pretendió realizar una investigación específica y homogénea, de manera que los cambios obtenidos en la inteligencia y la memoria en las diferentes edades se deban al tratamiento en sí, y no a la influencia de otros factores. Para esto, se aplicó un tratamiento que consistió en realizar ejercicio aeróbico subiendo y bajando una grada de 27 cm. de alto x 30 cm. de ancho, durante 10 minutos, a una intensidad del 60% de la frecuencia cardíaca máxima. Los sujetos fueron 100 hombres con edades entre la niñez y la edad avanzada. Se ubicaron en 5 subgrupos que realizaron un 'pretest', el tratamiento indicado y un 'postest'. Las pruebas fueron el test de Raven para la inteligencia y el Verbal Script Digit Span para medir la memoria auditiva. Para conocer los resultados se realizó un análisis de varianza Anova 5x2x2 para grupos independientes, utilizando los puntajes obtenidos en las diferencias entre 'pretest' y 'postest', para ambas variables, con su respectivo 'post-hoc' en los casos requeridos. Y para determinar la magnitud del cambio, se obtuvo los tamaños del efecto. Se encontró que con ejercicio aeróbico submaximal, la totalidad de los grupos etarios mejoraron sus resultados en el test de memoria con mejor resultado los de edades promedio de 25.5 y 63.25 años. Para la variable de inteligencia los sujetos de 34.75 y 52.4 años en promedio lograron los mejores resultados, mientras que los jóvenes de 25.5 años y los adultos mayores no tuvieron cambio significativo en este aspecto.

    2005-01-01

    Faced with the need to import increasing volumes of crude oil and the desire to avoid over-dependence on the Middle East, the United States is looking to its own hemisphere for more oil. Unfortunately for Washington, the continent's largest oil exporter does not appear to want to co-operate. Venezuela's President, Hugo Chavez, wants to reduce his country's political and economic ties with the US and is seeking other markets for its oil. He has also picked a fight with US oil companies operating in Venezuela, disputing their taxes and refusing to approve their upstream investment programmes, giving rise to fears that oil and gas production will not grow as planned, thereby reducing future export levels.

    2010-12-01

    Full Text Available El delito de secuestro es un flagelo social que ha experimentado mutaciones en el tiempo. El año 2009 terminó con una cifra sin precedentes en cuanto a los secuestros reportados en Venezuela. Los datos aportados por los organismos oficiales revelan que durante el 2008 hubo 537 secuestros, lo cual representa un aumento de 52% respecto al total del 2007, mientras que en el 2009 la cifra se incrementó en un 62,82%, en relación con el año anterior. Esta investigación tiene como objetivo describir el delito de secuestro en Venezuela, con especial referencia al Estado Zulia, población fronteriza limítrofe con Colombia. Para ello se emplea una metodología de tipo documental- descriptiva. Se revela que no existen esquemas predefinidos que permitan caracterizar este tipo penal, pues, tal y como ha venido sucediendo, es susceptible de llevarse a cabo en cualquier momento y circunstancia, no de modo exclusivo en sujetos de alto estatus socioeconómico, sino con mínimos medios para responder a las exigencias de los plagiarios; de aquí la proliferación de la modalidad del llamado secuestro exprés. El delito de secuestro en Venezuela ha cambiado en forma notable sus patrones: de ser un delito predominantemente político, fronterizo y ejecutado por grupos organizados, ha pasado a ser uno de objetivos sobre todo económicos, urbano, y ejecutado con un fin de lucro por la delincuencia común. En verdad, el Estado Zulia sigue repuntando en la lista de los estados con mayor incidencia de este delito en Venezuela, pero no es el principal, pues ha sido desplazado en posicionamiento por otras urbes del país, encabezadas en la actualidad por la ciudad capital de Caracas.

  8. Decúbito prono en pacientes con síndrome de distrés respiratorio agudo

    Mariano Setten

    Full Text Available RESUMEN El síndrome de distrés respiratorio agudo ocupa gran atención en la unidad de cuidados intensivos. A pesar del amplio conocimiento alcanzado sobre la fisiopatología de éste síndrome, el enfoque en la unidad de cuidados intensivos consiste, en gran parte, en un tratamiento de soporte vital y en evitar los efectos secundarios de las terapéuticas invasivas. Si bien, durante los últimos 20 años, se generaron grandes avances en ventilación mecánica con un impacto importante sobre la mortalidad, ésta continúa siendo elevada. Una característica de los pacientes con síndrome de distrés respiratorio agudo, sobre todo los más severos, es la presencia de hipoxemia refractaria debido a la existencia de shunt, pudiendo requerir tratamientos adicionales a la ventilación mecánica, entre ellos la ventilación mecánica en decúbito prono. Este método, recomendado para mejorar la oxigenación por primera vez en 1974, puede ser implementado fácilmente en cualquier unidad de cuidados intensivos con personal entrenado. El decúbito prono tiene un sustento bibliográfico sumamente robusto. Varios ensayos clínicos randomizados han demostrado el efecto del decúbito prono sobre la oxigenación en pacientes con síndrome de distrés respiratorio agudo medida a través de la relación PaO2/FiO2 e incluso su impacto en el aumento de la sobrevida de estos pacientes. Los integrantes del Comité de Kinesiología Intensivista de la Sociedad Argentina de Terapia Intensiva realizaron una revisión narrativa con el objetivo de exponer la evidencia disponible en relación a la implementación del decúbito prono, los cambios producidos en el sistema respiratorio por la aplicación de la maniobra y su impacto sobre la mortalidad. Por último, se sugerirán lineamientos para la toma de decisiones.

  12. Risk, Activism, and Empowerment: Women's Breast Cancer in Venezuela.

    Eid, Mahmoud; Nahon-Serfaty, Isaac

    2015-01-01

    The prevalence of breast cancer in Venezuela is particularly alarming, which is attributed to healthcare inequalities, low health literacy, and lagging compliance with prevention methods (i.e., screening and mammography). While the right to health is acknowledged by the Venezuelan constitution, activism beyond governmental confines is required to increase women's breast cancer awareness and decrease mortality rates. Through the development of social support and strategic communicative methods enacted by healthcare providers, it may be possible to empower women with the tools necessary for breast cancer prevention. This paper discusses issues surrounding women's breast cancer, such as awareness of the disease and its risks, self-advocacy, and the roles of activists, healthcare providers, and society. Specifically, it describes a four-year action-oriented research project developed in Venezuela, which was a collaborative work among researchers, practitioners, NGOs, patients, journalists, and policymakers. The outcomes include higher levels of awareness and interest among community members and organizations to learn and seek more information about women's breast cancer, better understandings of the communicated messages, more media coverage and medical consultations, increasing positive patient treatments, expansion of networking of NGOs, as well as a widely supported declaration for a national response against breast cancer in Venezuela.

  14. Egalitarian policies and social determinants of health in Bolivarian Venezuela.

    Muntaner, Caries; Benach, Joan; Páez Victor, María; Ng, Edwin; Chung, Haejoo

    2013-01-01

    In 1999, newly-elected Venezuelan President Hugo Chávez initiated a far-reaching social movement as part of a political project known as the Bolivarian Revolution. Inspired by the democratic ideologies of Simón Bolívar, this movement was committed to reducing intractable inequalities that defined Venezuela's Fourth Republic (1958-1998). Given the ambitious scope of these reforms, Venezuela serves as an instructive example to understand the political context of social inequalities and population health. In this article, we provide a brief overview of the impact of egalitarian policies in Venezuela, stressing: (a) the socialist reforms and social class changes initiated by the Bolivarian Movement; (b) the impact of these reforms and changes on poverty and social determinants of health; (c) the sustainability of economic growth to continue pro-poor policies; and (d) the implications of egalitarian policies for other Latin American countries. The significance and implications of Chávez's achievements are now further underscored given his recent passing, leading one to ask whether political support for Bolivarianism will continue without its revolutionary leader.

  15. Violence in Venezuela: oil rent and political crisis

    Roberto Briceño-León

    2006-06-01

    Full Text Available This article analyzes the changes in violence in Venezuela during the last forty years. It links the ups and downs of the oil revenues and the political crisis of the country to the changes in the homicide rates, which increased from 7 per 100 thousand inhabitants in 1970 to 12 in 1990, 19 in 1998 and 50 in 2003. The article characterizes Venezuela as a rentist society and shows its trajectory from rural violence to the beginning of urban violence, the guerilla movements of the 60s, the delinquent violence related to the abundance of oil revenues and the violence during the popular revolt and the sackings of 1989 in Caracas. After this, we analyze the coups d'état of 1992 and the influence the political violence exerted upon criminal violence. We describe the political and party changes in the country, their influence upon the stabilization of homicide rates since the mid-90s and their remarkable increase during the H. Chávez government. The article finishes with an analysis of the current situation, the official prohibition to publish statistics on homicides and with some thoughts about the perspective of greater violence in Venezuela.

  16. Interruption of Onchocerca volvulus transmission in Northern Venezuela

    2013-01-01

    Background Onchocerciasis is caused by Onchocerca volvulus and transmitted by Simulium species (black flies). In the Americas, the infection has been previously described in 13 discrete regional foci distributed among six countries (Brazil, Colombia, Ecuador, Guatemala, Mexico and Venezuela) where more than 370,000 people are currently considered at risk. Since 2001, disease control in Venezuela has relied on the mass drug administration to the at-risk communities. This report provides empirical evidence of interruption of Onchocerca volvulus transmission by Simulium metallicum in 510 endemic communities from two Northern foci of Venezuela, after 10–12 years of 6-monthly Mectizan® (ivermectin) treatment to all the eligible residents. Methods In-depth entomologic and epidemiologic surveys were serially conducted from 2001–2012 in selected (sentinel and extra-sentinel) communities from the North-central (NC) and North-east (NE) onchocerciasis foci of Venezuela in order to monitor the impact of ivermectin treatment. Results From 2007–2009, entomological indicators in both foci confirmed that 0 out of 112,637 S. metallicum females examined by PCR contained L3 infection in insect heads. The upper bound of the 95% confidence intervals of the infective rate of the vector reached values below 1% by 2009 (NC) and 2012 (NE). Additionally, after 14 (NC) and 22 (NE) rounds of treatment, the seasonal transmission potential (±UL CIs) of S. metallicum was under the critical threshold of 20 L3 per person per season. Serological analysis in school children < 15 years-old demonstrated that 0 out of 6,590 individuals were harboring antibodies to Ov-16. Finally, epidemiological surveys made during 2010 (NC) and 2012 (NE) showed no evidence of microfilariae in the skin and eyes of the population. Conclusions These results meet the WHO criteria for absence of parasite transmission and disease morbidity in these endemic areas which represent 91% of the population previously at

    Full Text Available Fundamento: Pacientes com insuficiência cardíaca (IC apresentam disfunção ventricular esquerda e redução da pressão arterial média (PAM. O aumento do estímulo adrenérgico causa vasoconstrição e resistência dos vasos, mantendo a PAM, enquanto aumenta a resistência vascular periférica e a rigidez dos vasos condutores. O aumento da pressão de pulso (PP reflete a complexa interação do coração com os sistemas arteriais e venosos. O aumento da PP é um importante marcador de risco em pacientes com insuficiência cardíaca crônica (ICC. A ventilação não invasiva (VNI tem sido utilizada para IC aguda descompensada para melhorar a congestão e a ventilação pelos efeitos respiratórios e hemodinâmicos. No entanto, nenhum desses estudos relatou o efeito da VNI na PP. Objetivo: O objetivo deste estudo foi determinar os efeitos agudos da VNI com CPAP (pressão positiva contínua nas vias aéreas sobre a PP em pacientes ambulatoriais com ICC. Métodos: Seguindo um protocolo randomizado, duplo-cego, cruzado e controlado com placebo, 23 pacientes com ICC (17 homens, 60 ± 11 anos, IMC 29 ± 5 kg/cm2, classes II e III da NYHA foram submetidos à CPAP via máscara nasal durante 30 minutos na posição reclinada. A pressão da máscara foi de 6 cmH2O, enquanto o placebo foi fixado em 0-1 cmH2O. PP e outras variáveis hemodinâmicas não invasivas foram avaliadas antes, durante e depois do placebo e do modo CPAP. Resultados: A CPAP diminuiu a frequência cardíaca de repouso (pré: 72 ± 9; pós 5 min: 67 ± 10 bpm , p < 0,01 e PAM (CPAP: 87 ± 11; controle 96 ± 11 mmHg , p < 0,05 pós 5 min. A CPAP diminuiu a PP (CPAP: 47 ± 20 pré para 38 ± 19 mmHg pós; controle: 42 ± 12 mmHg, pré para 41 ± 18 pós p < 0,05 pós 5 min. Conclusão: A VNI com CPAP diminuiu a pressão de pulso em pacientes com ICC estável. Ensaios clínicos futuros devem investigar se esse efeito está associado com melhora no desfecho clínico.

    Full Text Available RESUMO Introdução: O exercício físico é um fator importante do tratamento do diabetes mellitus. Objetivo: Verificar o efeito agudo dos exercícios intermitentes sobre glicemia e oxidação de substratos energéticos em adolescentes com diabetes tipo 1. Métodos: Foram avaliados 10 adolescentes diabéticos com idade entre 10 e 15 anos. Foram avaliadas as medidas antropométricas, hemoglobina glicosilada (HbA1c, VO2máx e o teste de exercício intermitente. Nesse teste, os indivíduos permaneceram pedalando por 30 minutos em cicloergômetro com carga de 60% do VO2máx, intercalados com tiros de intensidades máximas de 10 segundos a cada 5 minutos. Os substratos energéticos foram avaliados durante o teste e a glicemia capilar foi medida antes, imediatamente após o exercício e 30 minutos depois. Foi observada redução média da glicemia de 39,2 ± 41,92 mg/dl, isto é, média de 21,61% da glicemia inicial. Ocorreu diferença significativa (0,0001 entre os substratos energéticos oxidados, com predominância da utilização de CHO. Há uma forte correlação direta entre a HbA1c e o escore z do IMC (r = 0,821, p = 0,004 e entre HbA1c e glicose observadas pós-exercício (r = 0,702, p = 0,024 e também há forte correlação entre os níveis de glicose pré-exercício e pós-exercício (r = 0,851, p = 0,002 e entre pós-exercício e 30 minutos depois do exercício (r = 0,874, p = 0,001. O teste de regressão linear mostrou que o escore z do IMC explica 67% dos valores de HbA1c (r² = 0,675. Resultados: De acordo com os resultados observados, 30 minutos de exercícios aeróbicos intermitentes intercalados com tiros curtos de 10 segundos promovem redução média de 21% da glicemia, com tendência de aumento na fase de recuperação. O substrato energético predominante na atividade são os carboidratos (CHO. Conclusão: Quanto melhor for o escore z do IMC do adolescente, espera-se melhor controle glicêmico em adolescentes com diabetes tipo 1.

  3. O que todo intensivista deve saber a respeito da síndrome do desconforto respiratório agudo e dano alveolar difuso?

    Fernando Rios

    2017-09-01

    Full Text Available RESUMO A síndrome do desconforto respiratório agudo é um desafio para o intensivista. A característica principal desta doença aguda é o dano alveolar difuso, presente em cerca de metade dos pacientes com a síndrome. É claro que o suporte respiratório à síndrome do desconforto respiratório agudo tem melhorado gradualmente nas últimas décadas. É também evidente que todos estes procedimentos são benéficos, já que reduzem a lesão pulmonar e mantêm o paciente vivo. Isto deve ser interpretado como uma estratégia de ganho de tempo, até que o fator desencadeante ou de risco causal melhore, assim como a tempestade inflamatória diminua e o pulmão se cure. Por outro lado, todos - exceto dois tratamentos farmacológicos (bloqueadores neuromusculares e esteroides - são incapazes de melhorar o desfecho da síndrome do desconforto respiratório agudo. A hipótese de que os resultados farmacológicos negativos podem ser explicados pela heterogeneidade histológica da síndrome do desconforto respiratório agudo tem sido apoiada pelas recentes demonstrações de que a síndrome com dano alveolar difuso tem característica clínico-patológica específica. O dano alveolar difuso é um diagnóstico patológico, e a biópsia pulmonar a céu aberto (a técnica mais comum para obtenção de tecido pulmonar tem efeitos colaterais graves, sendo necessário que se desenvolvam biomarcadores substitutos para o dano alveolar difuso. O objetivo desta revisão é discutir três tópicos relacionados à síndrome do desconforto respiratório agudo: o relacionamento entre a síndrome do desconforto respiratório agudo e o dano alveolar difuso; como o dano alveolar difuso pode ser representado no quadro clínico; e como o enriquecimento pode melhorar os resultados de estudos clínicos farmacológicos realizados com pacientes com a síndrome e com dano alveolar difuso.

    1991-01-01

    This paper reports on Venezuela which continues efforts to position itself in world markets to capitalize on fallout from the Persian Gulf war. The central government and state oil company Petroleos de Venezuela SA have accelerated already ambitious plans to expand activities in upstream and downstream oil and gas sectors. Pvdsa has sharply increased its 1991-96 investment program from the level planned at the end of last year. The goal is to put Venezuela on a par with major Persian Gulf oil exporters in terms of productive capacity. Linchpin of those efforts could well be further steps toward privatization of Venezuela's oil sector. For the first time since nationalization in 1976, private foreign and domestic companies are being permitted to participate in Venezuelan exploration and development. In addition, the government is trimming the onerous tax burden the oil sector has carried in Venezuela, as well as its heavy subsidy of domestic petroleum products

    1993-01-01

    The number of cadaveric kidneys available for transplantation has become insufficient around the world. Despite concerted efforts, we have been unsuccessful in greatly improve the supply of organ donors, and consequently the number of end stage renal failure patients awaiting for kidney transplantation continues to increase. The primary objective of this paper is to quantify the need and supply of kidneys for transplant in Venezuela. An overview of the current level of kidney transplant activity in Venezuela is presented, observing that the activity with cadaveric donors had been predominant since 1983, although not to an optimal level. The annual activity in kidney transplant between 1989-1991 remained stable in 6 transplants/million people, but went sharply down to 4.6 in 1992. An estimate of the current need is around 10 donors/million people. This is in contrast with an effective donation rate of only 2.01 and 1.92 donors/million achieved in 1990 and 1991 respectively. The most frequent cause for no donation was the lack of familiar consent. Based on an analysis of the factors involved in the shortage of donor supply in Venezuela, we present some recommendations to increase the availability of cadaveric organ donors in the country. These measures include an improvement of education and legal regulation in the field of organ donation and transplantation, and following the Spanish model, the creation of a program of hospital transplant coordinators that can detect and evaluate potential organ donors as well as coordinate the logistical aspects of transplantation.

    SSNTD were used across tectonic features of different degree of activity and lithology in four localities north of Caracas, Venezuela. The homemade dosimeters with LR115 film were buried 20-30 cm in the ground. This cheap and low- tech method proved very useful to understand the tectonic features involved, measuring higher Radon concentration above traces of active faults while in old and sealed faults the results only show the effect of the surrounding lithology. Radon concentration range is 4.3 - 27.2 kB/m 3 . (Author)

    Uranium exploration started in Venezuela in 1951. The activities began with enthusiasm but interest waned because of the unfavourable economic conditions of the uranium market. In 1975, with the establishment of the National Council for the Development of the Nuclear Industry, emphasis was once again placed on exploration for radioactive minerals. Systematic exploration began 18 months ago, and so far exploratory targets have been found in phosphate rocks in Tachira state and in Palaeozoic granites at El Baul (Cojedes state); very favourable occurrences have been encountered in the Precambrian in Merida and Bolivar states, and in continental Tertiary rocks in Trujillo state.

    Shelley MCCONNEL

    2015-08-01

    Full Text Available International election monitoring has been touted as a regional norm in the Western hemisphere, but recent reforms in Venezuela and Nicaragua substituted a diminished international role of electoral accompaniment. This article traces the initial acceptance and later limitation of international election monitoring in those countries to explore whether the change constitutes norm localization or norm defection. It concludes that the norm is not as well institutionalized in the hemisphere as conventionally thought, and that models need to assess together national and international monitoring capacities.

    Two native Yanomami children from the Venezuelan Amazonia with erythroderma were hospitalized on our service. Clinical, histologic, and immunofluorescence studies diagnosed endemic pemphigus foliaceous. Human leukocyte antigen class II showed DRB1*04 subtype *0411, which has not been previously associated with this disease. However, it shares a common epitope with all the human leukocyte antigen DRB1 alleles that have been involved in this disease among Brazilian populations. Although this condition is endemic in Brazil, our patients are the first two reported in Venezuela.

    Sarabia, A.; Cifuentes, H.; Altez Ortega, R.; Palme, C.; Dimate, C.

    2013-05-01

    After the publication of the SISRA (CERESIS-1985) regional project, a unified catalog of seismic parameters and intensities for South America, researchers in historical seismicity have continued advancing on different scales in the area of this study of seismic hazard. The most important initiatives carried out in this area in Colombia and Venezuela can be grouped as follows: a) Reviews of destructive earthquakes in national and international historic archives, principally by Altez and FUNVISIS in Venezuela and Espinosa, Salcedo, and Sarabia et al in Colombia, leading to the preparation of seismologic catalogues, scientific and dissemination articles, reports, books, among others. b) Organization and systematization of historic information to develop public domain data bases and information, specifically the Historic Seismologic Teleinformation System in Venezuela, carried out between 2004 and 2008 under the coordination of Christl Palme and accessible on-line: http://sismicidad.ciens.ula.ve. As well, the "Historia Sísmica de Colombia 1550-1830" (Seismic History in Colombia 1550-1830) data base, in CD-ROM, by Espinosa Baquero (2003) and the historic seismicity information system of Colombia (Servicio Geológico Colombiano-Universidad Nacional de Colombia), published on the internet in 2012: http://agata.ingeominas.gov.co:9090/SismicidadHistorica/. c) Macroseismic studies for the development of intensity attenuation equations and the quantification and revaluation of basic historic earthquake parameters using isoseismal maps (Rengifo et al., Palme et al., Salcedo et al., among others) and procedures such as Boxer and Bakun & Wentworth (Palme et al., Dimaté, among others), which have produced significant changes in the parameters of some of the large earthquakes. d) Symposiums of researchers to promote interest and development in the discipline, including Jornadas Venezolanas de Sismología Histórica (Venezuelan Congress of Historical Seismology), held

  12. Interrupting Chagas disease transmission in Venezuela A interrupção da transmissão da doença de Chagas na Venezuela

    Alberto ACHÉ

    2001-02-01

    Full Text Available The interruption of vectorial transmission of Chagas disease in Venezuela is attributed to the combined effects of ongoing entomoepidemiological surveillance, ongoing house spraying with residual insecticides and the concurrent building and modification of rural houses in endemic areas during almost five decades. The original endemic areas which totaled 750,000 km², have been reduced to 365,000 km². During 1958-1968, initial entomological evaluations carried out showed that the house infestation index ranged between 60-80%, the house infection index at 8-11% and a house density index of 30-50 triatomine bugs per house. By 1990-98, these indexes were further reduced to 1.6-4.0%, 0.01-0.6% and 3-4 bugs per house respectively. The overall rural population seroprevalence has declined from 44.5% (95% C.I.: 43.4-45.3% to 9.2% (95% C.I.: 9.0-9.4% for successive grouped periods from 1958 to 1998. The annual blood donor prevalence is firmly established below 1%. The population at risk of infection has been estimated to be less than four million. Given that prevalence rates are stable and appropriate for public health programmes, consideration has been given to potential biases that may distort results such as: a geographical differences in illness or longevity of patients; b variations in levels of ascertainment; c variations in diagnostic criteria; and d variations in population structure, mainly due to appreciable population migration. The endemic areas with continuous transmission are now mainly confined to piedmonts, as well as patchy foci in higher mountainous ranges, where the exclusive vector is Rhodnius prolixus. There is also an unstable area, of which landscapes are made up of grasslands with scattered broad-leaved evergreen trees and costal plains, where transmission is very low and occasional outbreaks are reported.A interrupção da transmissão da doença de Chagas é atribuida aos efeitos conjuntos da vigilância soroepidemiol

    Full Text Available Embora a atenção ao idoso seja uma prioridade emergente no Brasil, pouca ênfase tem sido dada a modelos de organização de serviços hospitalares para pacientes geriátricos. São revisados modelos de serviços hospitalares para admissão e manuseio de casos agudos em idosos, com ênfase na discussão sobre o papel e o posicionamento da medicina geriátrica (incluindo sua interface com especialidades e com a clínica médica no âmbito da atenção hospitalar. Foi realizada pesquisa na base de dados Medline (1989-1999, bem como nos principais livros-texto de geriatria e de gerontologia, buscando identificar descrições de serviços hospitalares para cuidado agudo de pacientes idosos. As características dos modelos identificados foram compiladas e descritas à luz de sua adequação à realidade dos serviços de saúde no Brasil. Exemplos de intervenções em geriatria, com efetividade demonstrada através de revisões sistemáticas, foram também citadas. Os modelos mais freqüentemente relatados foram cuidado prolongado, tradicional, baseado na idade cronológica, não especializado e integrado. Adaptações e variantes de alguns desses modelos foram freqüentemente relatadas, assim como seu impacto potencial na efetividade do cuidado geriátrico. Evidências sobre o melhor modelo a seguir não foram identificadas, mas aqueles modelos favorecendo a integração da geriatria com a clínica geral pareceram mais adequados à nossa realidade. Ressalta a necessidade de reestruturação de serviços de saúde para responder às novas demandas que surgem com o envelhecimento da população, bem como do delineamento de serviços hospitalares para casos agudos, importantes para a efetividade do cuidado geriátrico e que devem ser objeto de maior debate e pesquisa no Brasil.Although the implementation of geriatric services is an emerging priority in Brazil, little emphasis has been put on the type of acute care that should be provided for elderly

  17. The periodicity of Plasmodium vivax and Plasmodium falciparum in Venezuela.

    Grillet, María-Eugenia; El Souki, Mayida; Laguna, Francisco; León, José Rafael

    2014-01-01

    We investigated the periodicity of Plasmodium vivax and P. falciparum incidence in time-series of malaria data (1990-2010) from three endemic regions in Venezuela. In particular, we determined whether disease epidemics were related to local climate variability and regional climate anomalies such as the El Niño Southern Oscillation (ENSO). Malaria periodicity was found to exhibit unique features in each studied region. Significant multi-annual cycles of 2- to about 6-year periods were identified. The inter-annual variability of malaria cases was coherent with that of SSTs (ENSO), mainly at temporal scales within the 3-6 year periods. Additionally, malaria cases were intensified approximately 1 year after an El Niño event, a pattern that highlights the role of climate inter-annual variability in the epidemic patterns. Rainfall mediated the effect of ENSO on malaria locally. Particularly, rains from the last phase of the season had a critical role in the temporal dynamics of Plasmodium. The malaria-climate relationship was complex and transient, varying in strength with the region and species. By identifying temporal cycles of malaria we have made a first step in predicting high-risk years in Venezuela. Our findings emphasize the importance of analyzing high-resolution spatial-temporal data to better understand malaria transmission dynamics. Copyright © 2013 Elsevier B.V. All rights reserved.

    Chagas disease is an endemic zoonosis native to the Americas and is caused by the kinetoplastid protozoan parasite Trypanosoma cruzi. The parasite is also highly genetically diverse, with six discrete typing units (DTUs) reported TcI – TcVI. These DTUs broadly correlate with several epidemiogical, ecological and pathological features of Chagas disease. In this manuscript we report the most comprehensive evaluation to date of the genetic diversity of T. cruzi in Venezuela. The dataset includes 778 samples collected and genotyped over the last twelve years from multiple hosts and vectors, including nine wild and domestic mammalian host species, and seven species of triatomine bug, as well as from human sources. Most isolates (732) can be assigned to the TcI clade (94.1%); 24 to the TcIV group (3.1%) and 22 to TcIII (2.8%). Importantly, among the 95 isolates genotyped from human disease cases, 79% belonged to TcI - a DTU common in the Americas, however, 21% belonged to TcIV- a little known genotype previously thought to be rare in humans. Furthermore, were able to assign multiple oral Chagas diseases cases to TcI in the area around the capital, Caracas. We discuss our findings in the context of T. cruzi DTU distributions elsewhere in the Americas, and evaluate the impact they have on the future of Chagas disease control in Venezuela. PMID:22745843

    Free-living amoebae of Acanthamoeba genus are opportunistic pathogens distributed worldwide. Strains included in this genus are causative agents of a fatal encephalitis and a sight-threating keratitis in humans and other animals. In this study, 550 clinical samples which were collected between 1984 and 2014 from different patients with suspected infections due to Acanthamoeba were initially screened for the presence of this amoebic genus at the Laboratorio de Amibiasis-Escuela de Bioanálisis at the Universidad Central de Venezuela. Samples were cultured in 2% Non-Nutrient agar plates seeded with a layer of heat killed Escherichia coli. From the 550 clinical samples included in this study, 18 of them were positive for Acanthamoeba genus after culture identification. Moreover, positive samples were confirmed after amplification of the Diagnostic Fragment 3 (DF3) of the Acanthamoeba18S rDNA genus and sequencing was carried out in order to genotype the isolated strains of Acanthamoeba. Furthermore, the pathogenic potential of the strains was checked by performing thermotolerance and osmotolerance assays. Sequencing of the DF3 region resulted in the identification of genotype T4 in all the isolated strains. Moreover, most isolates were thermotolerant or both thermotolerant and osmotolerant and thus were classified as potentially pathogenic strains. To the best of our knowledge, this is the first report on the molecular characterization at the genotype level of Acanthamoeba strains in Venezuela.

  20. AMINOGLYCOSIDE RESISTANCE GENES IN Pseudomonas aeruginosa ISOLATES FROM CUMANA, VENEZUELA.

    Teixeira, Bertinellys; Rodulfo, Hectorina; Carreño, Numirin; Guzmán, Militza; Salazar, Elsa; De Donato, Marcos

    2016-01-01

    The enzymatic modification of aminoglycosides by aminoglycoside-acetyltransferases (AAC), aminoglycoside-adenyltransferases (AAD), and aminoglycoside-phosphotransferases (APH), is the most common resistance mechanism in P. aeruginosa and these enzymes can be coded on mobile genetic elements that contribute to their dispersion. One hundred and thirty seven P. aeruginosa isolates from the University Hospital, Cumana, Venezuela (HUAPA) were evaluated. Antimicrobial susceptibility was determined by the disk diffusion method and theaac, aadB and aph genes were detected by PCR. Most of the P. aeruginosa isolates (33/137) were identified from the Intensive Care Unit (ICU), mainly from discharges (96/137). The frequency of resistant P. aeruginosaisolates was found to be higher for the aminoglycosides tobramycin and amikacin (30.7 and 29.9%, respectively). Phenotype VI, resistant to these antibiotics, was the most frequent (14/49), followed by phenotype I, resistant to all the aminoglycosides tested (12/49). The aac(6´)-Ib,aphA1 and aadB genes were the most frequently detected, and the simultaneous presence of several resistance genes in the same isolate was demonstrated. Aminoglycoside resistance in isolates ofP. aeruginosa at the HUAPA is partly due to the presence of the aac(6´)-Ib, aphA1 andaadB genes, but the high rates of antimicrobial resistance suggest the existence of several mechanisms acting together. This is the first report of aminoglycoside resistance genes in Venezuela and one of the few in Latin America.

  1. End-stage renal disease and its treatment in Venezuela.

    Bellorin-Font, Ezequiel; Milanés, Carmen Luisa; Rodríguez-Iturbe, Bernardo

    2002-09-01

    In Venezuela there are 3234 new cases (132 per million population [pmp]) requiring renal replacement therapy each year, and only 40% of these are admitted to the different modalities of dialysis. In the year 2000, there were 195 patients pmp in chronic hemodialysis (4700 patients). Diabetes, glomerular diseases, and hypertension account for more than 60% of the patients in chronic dialysis. Gross mortality in hemodialysis is around 20%, and cardiovascular causes are the primary cause of death (39.5%). Hospital admission in the dialysis patients amounts to 4.6 days/patient/year. Rehabilitation is inadequate. Only 45% of the dialysis patients report normal home or work activities. Transplantation in Venezuela has a general graft survival rate of 83% at 1 year (90% for living related grafts) and 50% (64% for living related grafts) at 10 years. Future tendencies include emphasis in preventive strategies, including early detection and treatment of diabetes and hypertension, as well as efforts to increase the rate of renal transplantation.

  2. Urban movements and disempowerment in Perú and Venezuela

    Daniel H. LEVINE

    2010-10-01

    Full Text Available This paper addresses a core puzzle: why is continued citizen mobilization accompanied by growing disempowerment of those same citizens? Why do movements fail, leaders burn out and members disperse, and what are the implications of this organizational failure for demo¬cratic representation? Our consideration of the issues is rooted in a close examination of urban movements, mobilization, empowerment and disempowerment in the recent experience of Venezuela and Perú. The puzzle that concerns us is of course not limited to these two countries: it is common to all the Andean republics, and in different ways, to much recent experience of urban mobilization in Latin America and beyond. After a brief account of urban citizen move¬ments and politics in our two cases, we outline general reflections on the nature of empowerment and disempowerment, on the peculiar combination of strengths and weaknesses that mark many contemporary movements. A close examination of types of movements and their links with poli¬tical parties and protest follows. The character of city life is important here. We close with analysis of recent waves of urban mobilization in Perú (that sparked the ouster of president Alberto Fujimori and in Venezuela (both for and against president Hugo Chávez Frías, and with reflections on the likely future of empowerment and disempowerment for urban citizens and the implications of this perspective for democratic representation

    The integration and use of different space technology applications for disasters management, play an important role at the time of prevents the causes and mitigates the effects of the natural disasters. Nevertheless, the space technology counts with the appropriate technological resources to provide the accurate and timely information required to support in the decision making in case of disasters. Considering the aforementioned aspects, in this research is presented the design and implementation of an Emergency Communications Network for Disasters Management in Venezuela. Network based on the design of a topology that integrates the satellites platforms in orbit operation under administration of Venezuelan state, such as: the communications satellite VENESAT-1 and the remote sensing satellites VRSS-1 and VRSS-2; as well as their ground stations with the aim to implement an emergency communications network to be activated in case of disasters which affect the public and private communications infrastructures in Venezuela. In this regard, to design the network several technical and operational specifications were formulated, between them: Emergency Strategies to Maneuver the VRSS-1 and VRSS-2 satellites for optimal images capture and processing, characterization of the VENESAT-1 transponders and radiofrequencies for emergency communications services, technologies solutions formulation and communications links design for disaster management. As result, the emergency network designed allows to put in practice diverse communications technologies solutions and different scheme or media for images exchange between the areas affected for disasters and the entities involved in the disasters management tasks, providing useful data for emergency response and infrastructures recovery.

    Eid, Mahmoud; Nahon-Serfaty, Isaac

    2015-07-01

    Breast cancer incidence and mortality rates are of concern among Latin American women, mainly due to the growing prevalence of this disease and the lack of compliance to proper breast cancer screening and treatment. Focusing on Venezuelan women and the challenges and barriers that interact with their health communication, this paper looks into issues surrounding women's breast cancer, such as the challenges and barriers to breast cancer care, the relevant ethics and responsibilities, the right to health, breast cancer risk perception and risk communication, and the media interventions that affect Venezuelan women's perceptions and actions pertaining to this disease. In particular, it describes an action-oriented research project in Venezuela that was conducted over a four-year period of collaborative work among researchers, practitioners, NGOs, patients, journalists, and policymakers. The outcomes include positive indications on more effective interactions between physicians and patients, increasing satisfactions about issues of ethical treatment in providing healthcare services, more sufficient and responsible media coverage of breast cancer healthcare services and information, a widely supported declaration for a national response against breast cancer in Venezuela, and the creation of a code of ethics for the Venezuelan NGO that led the expansion of networking in support of women's breast cancer healthcare.

  6. Venezuela recasts itself as a new frontier in the Americas

    Reinsch, A.E.

    1996-01-01

    In January of this year, Venezuela captured the attention of the international energy community by welcoming back the foreign oil companies that, 20 years earlier, it had shut out of the country by nationalizing the hydrocarbon sector. The tool used to attract that attention, a new exploration bidding round, is the most publicized event staged to date in the country's aperture process. However, it is only the latest in a series of steps taken by officials to bring international oil and gas companies back to Caracas. Venezuela's physical attraction is easily understood. The country possesses roughly one-half of Latin America's (including Mexico) 125 billion bbl of established, conventional crude oil reserves, plus an estimated 300 billion bbl of additional, nonconventional reserves in the ultra-heavy crude belt of the Orinoco basin. Averaging 2.8 million bpd in 1996, Venezuelan crude production represents over 35% of regional oil output. Natural gas reserves total 138 Tcf, or just over one-half of the region's total reserves of 274 Tcfg. Annual gas output averages just under 5 Tcf, of which roughly 30% is reinjected as part of tertiary oil recovery schemes. This paper reviews the incentives, deregulation, and government policies to restore the oil and gas industry to the country

    Full Text Available Urban development together with uncontrolled construction in endemic areas of leishmaniasis has resulted in a series of environmental transformations that have promoted the spread of cutaneous leishmaniasis, with the adaptation sandflies transmitters to these urban environments. This study aims to determine the presence of sandflies and the epidemiological factors associated with the transmission of leishmaniasis in an urban area of Zea, Venezuela. Five methods of catching sandflies were used indoors in two urbanizations in Zea, Venezuela. Through a survey-type instrument, the epidemiological variables associated with the transmission of leishmaniasis in the housing estates were determined. The presence in the urban dwellings of Lutzomyia youngi, Lutzomyia spinicrassa, Lutzomyia migonei, Lutzomyia ovallesi, Lutzomyia walkeri, Lutzomyia venezuelensis, Lutzomyia atroclavata and Lutzomyia lichyi were demonstrated. 62.5% of the species caught in urbanized areas have antropohematophagy habits. A 67% and 80% of infestation was determined in the dwellings of the studied urbanizations. It was evidenced a low level of knowledge in the inhabitants mainly on the sandflies, which increases the risk of domiciliation and transmission of leishmaniasis, the control entities are warned to implement preventive and educational measures.

    2009-03-01

    Full Text Available A síndrome do desconforto respiratório agudo é caracterizada por uma reação inflamatória difusa do parênquima pulmonar, podendo ser induzida por um insulto direto ao epitélio alveolar (síndrome do desconforto respiratório agudo pulmonar ou indireto através do endotélio vascular (síndrome do desconforto respiratório agudo extrapulmonar. Acredita-se que uma terapia eficaz para o tratamento da síndrome do desconforto respiratório agudo deva atenuar a resposta inflamatória e promover adequado reparo da lesão pulmonar. O presente artigo apresenta uma breve revisão acerca do potencial terapêutico das células-tronco na síndrome do desconforto respiratório agudo. Essa revisão bibliográfica baseou-se em uma pesquisa sistemática de artigos experimentais e clínicos sobre terapia celular na síndrome do desconforto respiratório agudo incluídos nas bases de dados MedLine e SciELO nos últimos 10 anos. O transplante de células-tronco promove melhora da lesão inflamatória pulmonar e do conseqüente processo fibrótico, induzindo adequado reparo tecidual. Dentre os mecanismos envolvidos, podemos citar: diferenciação em células do epitélio alveolar e redução na liberação de mediadores inflamatórios e sistêmicos e fatores de crescimento. A terapia com células-tronco derivadas da medula óssea pode vir a ser uma opção eficaz e segura no tratamento da síndrome do desconforto respiratório agudo por acelerar o processo de reparo e atenuar a resposta inflamatória. Entretanto, os mecanismos relacionados à atividade antiinflamatória e antifibrogênica de tais células necessitam ser mais bem elucidados, limitando, assim, o seu uso clínico imediato.Acute respiratory distress syndrome is characterized by an acute pulmonary inflammatory process induced by the presence of a direct (pulmonary insult that affects lung parenchyma, or an indirect (extrapulmonary insult that results from an acute systemic inflammatory response

    2017-11-01

    Full Text Available It is a fact that the social dynamic of human life, in its constant evolution promotes special and particular circumstances that the law must regulate, such as tourism. The latter, as multifaceted activity, develops into different scopes of human activities: economic, social, cultural, environmental, political and obviously, in the judicial, and requires to be regulated, supervised, encouraged and coordinated by the law. This compendium of rules integrates what is known as the Legal System Structure of the Tourism in Venezuela and they are organized in a hierarchical way, into a legal level that gives a determinate rank, which can be the same or different, and could be seen in the pyramidal model created by Hans Kelsen. The understanding of this legal system that regulates tourism through the compressive hermeneutics of its rules, allowed to find out that the legal structure is well defined within the Venezuelan touristic context. The analysis of results allowed to conclude that the norm that regulates the tourism activity in Venezuela responds to the Kelsen pyramidal model and there is a diverse number of legal instruments which contain rules that regulates it in direct way and others indirectly.

  18. The Crustal Structure and Seismicity of Eastern Venezuela

    Schmitz, M.; Martins, A.; Sobiesiak, M.; Alvarado, L.; Vasquez, R.

    2001-12-01

    Eastern Venezuela is characterized by a moderate to high seismicity, evidenced recently by the 1997 Cariaco earthquake located on the El Pilar Fault, a right lateral strike slip fault which marks the plate boundary between the Caribbean and South-American plates in this region. Recently, the seismic activity seems to migrate towards the zone of subduction of the Lesser Antilles in the northeast, where a mb 6.0 earthquake occurred in October 2000 at 120 km of depth. Periodical changes in the seismic activity are related to the interaction of the stress fields of the strike-slip and the subduction regimes. The seismic activity decreases rapidly towards to the south with some disperse events on the northern edge of the Guayana Shield, related to the Guri fault system. The crustal models used in the region are derived from the information generated by the national seismological network since 1982 and by microseismicity studies in northeastern Venezuela, coinciding in a crustal thickness of about 35 km in depth. Results of seismic refraction measurements for the region were obtained during field campains in 1998 (ECOGUAY) for the Guayana Shield and the Cariaco sedimentary basin and in 2001 (ECCO) for the Oriental Basin. The total crustal thickness decreases from about 45 km on the northern edge of the Guayana Shield to some 36 km close to El Tigre in the center of the Oriental Basin. The average crustal velocity decreases in the same sense from 6.5 to 5.8 km/s. In the Cariaco sedimentary basin a young sedimentary cover of 1 km thickness with a seismic velocity of 2 km/s was derived. Towards the northern limit of the South-American plate, no deep seismic refraction data are available up to now. The improvement of the crustal models used in that region would constitute a step forward in the analysis of the seismic hazard.

    2011-10-01

    Full Text Available En la presente revisión se presenta información sobre superficie, producción, y rendimiento de los frutales en Venezuela. Además se hacen consideraciones sobre los sistemas de producción, destacando limitaciones, avances y sugerencias. La fruticultura en Venezuela ocupa el 3er. lugar dentro del sector agrícola vegetal. Existen 167.691 Ha de frutales y una producción 2.232.088 TM por año. Se producen comercialmente una docena de rubros frutícolas, siendo los principales: plátano, banano, naranjo y piña. Las áreas de producción van desde zonas bajas y áridas, en donde se obtienen uvas y piñas; hasta zonas altas y húmedas donde se hallan duraznos y fresas. Ha habido reducción de la superficie plantada, con excepción de lechosa, piña y aguacate. El manejo hortícola de los huertos frutícolas es heterogéneo, ya que se observa desde bajo hasta alto nivel de tecnología. La incorrecta aplicación de las prácticas hortícolas origina baja productividad y calidad de fruta. La poscosecha podría mejorarse a través del desarrollo e implementación de normas de clasificación, empaque, embalaje, y cadena de frío. La exportación de frutas venezolanas se ha reducido en los últimos años y se concentra en mango, naranja y lima Tahití. Los principales destinos son Colombia, Europa, Norteamérica y las islas del Caribe. Sólo la naranja se procesa de manera importante en Venezuela. Las perspectivas para la fruticultura venezolana es continuar como una actividad dirigida al mercado interno, no se vislumbra una mayor participación del país en el mercado internacional.

  7. Paralytic Shellfish Poisoning (PSP in Margarita Island, Venezuela

    Amelia La Barbera-Sánchez

    2004-09-01

    Full Text Available A severe outbreak of Paralytic Shellfish Poisoning (PSP occurred in Manzanillo and Guayacán, northwestern coast of Margarita Island, Venezuela, between August and October 1991. A bloom of dinoflagellates including Prorocentrum gracile, Gymnodinium catenatum and Alexandrium tamarense seemed to be responsible for this outbreak. Levels of PSP toxins in mussels (Perna perna exceeded the international safety limit of saxitoxin, 80 µg STX/100 g meat. PSP toxin values varied between 2 548 and 115 µg STX/100 g meat in Manzanillo, and between 1 422 and 86 µg STX/100 g meat in Guayacán. At both locations, the highest levels were detected in August, when 24 patients exhibited typical symptoms of PSP toxicity after consuming cooked mussels (16 required hospitalization. A high pressure liquid chromatographic (HPLC procedure was recently used on the 1991 samples. The major toxin detected in samples of both locations was decarbamoyl saxitoxin (dcSTX, but low concentrations of saxitoxin were also found in Manzanillo samples. Gonyautoxins GTX1, GTX2 and GTX3 were detected only at Guayacán, while in both locations, decarbamoylgonyatouxin (dcGTX2,3 toxins were detected. These findings represent the first time that causative toxins of PSP in Venezuela have been chemically identified, and confirm the presence of dcSTX and dcGTX in mussels from the Caribbean Sea. The presence of dcSTX and dcGTX in shellfish is indicative that Gymnodinium catenatum was a causative organism for outbreak of PSPUn severo brote de intoxicación paralizante por moluscos (PSP en inglés ocurrió en Manzanillo y Guayacán en la costa noroeste de la Isla de Margarita, Venezuela entre agosto y octubre de 1991.

    2004-09-01

    The mineral content of the honey produced in five zones of the Zulia state, Venezuela, during dry and rainy seasons was determined. The analyzed elements were: sodium, potassium (by emission spectroscopy), calcium, magnesium, copper, iron, manganese (by atomic absorption spectroscopy), phosphorus (phosphate ions, by colorimetric method), and ash content of raw honey samples directly collected from different beekeepers. The mean values for Na, K, Ca, Mg, Cu, Fe, Mn, and P were 353+84; 1774+138; 237+66; 52+24; 0.76+0.43; 13.5+10.23; 0.92+0.42 and 1642+323 mg/kg respectively. The mean ash content was 0.431+0.15%. Potassium was the most abundant of the elements determined. This results confirm that Zulian honey can be considered a good source of minerals.

  9. Gamma environmental dosimetry and radon concentration in Venezuela

    Sajo B, L.; Greaves E, D.

    1996-01-01

    The environmental radiation levels have been determined in Venezuela by means of different techniques including the passive dosimeters and the alpha and gamma dosimetry besides the gross alpha/beta counting. The most important conclusion is that the presence of artificial radionuclides (Cesium-137, Beryllium-7 and Cadmium-109) was observed in different environmental samples and in food considered contaminant. The values of gamma levels are between 28 and 40 mGy/day and the mean value of radon concentration in closed environment is 36 Bq/m 3 ; the higher values of a factor 10 have been measured in the Andes region. The 20% of analysed drinking water has a concentration of alpha radionuclides emitters less than 0.005 Bq/l and only the 8% is greater than 0.450 Bq/l. (authors). 6 refs., 1 fig

  10. Transmission of Guanarito and Pirital Viruses among Wild Rodents, Venezuela

    Milazzo, Mary L.; Cajimat, Maria N.B.; Duno, Gloria; Duno, Freddy; Utrera, Antonio

    2011-01-01

    Samples from rodents captured on a farm in Venezuela in February 1997 were tested for arenavirus, antibody against Guanarito virus (GTOV), and antibody against Pirital virus (PIRV). Thirty-one (48.4%) of 64 short-tailed cane mice (Zygodontomys brevicauda) were infected with GTOV, 1 Alston’s cotton rat (Sigmodon alstoni) was infected with GTOV, and 36 (64.3%) of 56 other Alston’s cotton rats were infected with PIRV. The results of analyses of field and laboratory data suggested that horizontal transmission is the dominant mode of GTOV transmission in Z. brevicauda mice and that vertical transmission is an important mode of PIRV transmission in S. alstoni rats. The results also suggested that bodily secretions and excretions from most GTOV-infected short-tailed cane mice and most PIRV-infected Alston’s cotton rats may transmit the viruses to humans.

  11. Potential options to reduce GHG emissions in Venezuela

    Pereira, N.; Bonduki, Y.; Perdomo, M.

    1996-12-31

    The Government of Venezuela ratified the United Nations Framework Convention on Climate Change (UNFCCC) in December, 1994. The Convention requires all parties to develop and publish national inventories of anthropogenic greenhouse gas emissions (GHG) as well as national plans to reduce or control emissions, taking into account their common but differentiated responsibilities and their specific national and regional development priorities, objectives, and circumstances. Within this context, the Ministry of Environment and Renewable Natural Resources and the Ministry of Energy and Mines developed the `Venezuelan Case-Study to Address Climate Change`. The study was initiated in October 1993, with the financial and technical assistance of the Government of United States, through the U.S. Country Studies Program (USCSP), and the Global Environment Facility (GEF), through the United Nations Environment Programme (UNEP).

  12. Embodying racism: race, rhinoplasty, and self-esteem in Venezuela.

    Gulbas, Lauren E

    2013-03-01

    In this article, I examine how race motivates women's decisions to undergo aesthetic rhinoplasty in Caracas, Venezuela. Through a combination of cultural domain analysis and thematic analysis of qualitative interviews, I explore how the preference for whiteness and associated facial features dovetail with the aesthetic ideals promoted by cosmetic surgeons. Rhinoplasty is offered by physicians and interpreted by patients as a resolution to body dissatisfaction and low self-esteem. The clinical ethos of objectivity established by cosmetic surgeons fails to acknowledge how perceptions of the self and body are strongly tied to racial marginalization: patients' efforts to alter the nose reveal attempts to change not only how the body looks, but how it is lived. As a result, cosmetic surgery only acts as a stop-gap measure to heighten one's self-esteem and body image.

  13. Estados Unidos y Venezuela: Una relación necesaria.

    Carlos Romero.

    2002-09-01

    Full Text Available The author identifies Hugo Chavez's electoral victory and the implementation of a new type of democracy as two factors that transformed Venezuelan foreign policy, and in particular, the bilateral relationship with the United States. Chavez's international activism, in addition to his Bolivarian policy signaled a shift from "safe partner" to "partner with reservations" in the country's relations with Washington. Although Venezuela considered itself a Latin American showcase in previous years, the text argues that Chavez's populist tendencies, his critical posture towards the promotion of democracy and human rights, and his supposed links with Colombian guerrillas has led to a "wait-and-see" policy characterized by high levels of caution on the part of the United States.

    Full Text Available The eggshell fine structure of five sand fly species from Venezuela belonging to the genus Lutzomyia (L. migonei, L. ovallesi, L. absonodonta, L. gomezi and L. panamensis was examined by scanning electron microscopy. The chorionic sculpturing of L. migonei, L. ovallesi, L. absonodonta and L. gomezi was characterized by series of columns arranged in palisade to form sinuous ridges. In inter-ridge areas, the basal layer was covered with fibrous material. The outer chorion of L. panamensis had a pattern known as "mountain- or volcano-like". The morphology of the posterior pole and aeropyle had a common structure in the five species, with some species-specific characters. The eggshell features of the five species are compared with those of other phlebotomine sand flies.

  15. What does the failure to reduce homicides in Venezuela teach?

    Roberto Briceño-León

    2017-09-01

    Full Text Available This article addresses the paradox of increased homicides in Venezuela in a period of wealth and redistribution. To do so, theories that explain criminality through poverty and inequality are reviewed and refuted and weighed against theories of institutionalism. Thus, the article analyses the situation of homicides between 1985 and 2010 and establishes three periods in which the rules regulating access to a goods, b political power, and c social and penal control were broken. The theories are discussed with statistical information and interpreted within the economic and political context of the time. It is concluded that the reduction in homicides requires institutionalism based on sensitivity and certain formal and informal rules that allow the construction of legitimacy around social difference and punishment, and a citizens’ culture that favours social control by peers over penal control by the State.

    2016-01-01

    Full Text Available The enzymatic modification of aminoglycosides by aminoglycoside-acetyltransferases (AAC, aminoglycoside-adenyltransferases (AAD, and aminoglycoside-phosphotransferases (APH, is the most common resistance mechanism in P. aeruginosa and these enzymes can be coded on mobile genetic elements that contribute to their dispersion. One hundred and thirty seven P. aeruginosa isolates from the University Hospital, Cumana, Venezuela (HUAPA were evaluated. Antimicrobial susceptibility was determined by the disk diffusion method and theaac, aadB and aph genes were detected by PCR. Most of the P. aeruginosa isolates (33/137 were identified from the Intensive Care Unit (ICU, mainly from discharges (96/137. The frequency of resistant P. aeruginosaisolates was found to be higher for the aminoglycosides tobramycin and amikacin (30.7 and 29.9%, respectively. Phenotype VI, resistant to these antibiotics, was the most frequent (14/49, followed by phenotype I, resistant to all the aminoglycosides tested (12/49. The aac(6´-Ib,aphA1 and aadB genes were the most frequently detected, and the simultaneous presence of several resistance genes in the same isolate was demonstrated. Aminoglycoside resistance in isolates ofP. aeruginosa at the HUAPA is partly due to the presence of the aac(6´-Ib, aphA1 andaadB genes, but the high rates of antimicrobial resistance suggest the existence of several mechanisms acting together. This is the first report of aminoglycoside resistance genes in Venezuela and one of the few in Latin America.

  2. Reactor, radioactive isotopes and nuclear energy: their avatars in Venezuela

    Roche, M

    1981-03-01

    The decision to bring a fair sized (3MW) research reactor to Venezuela, made in 1954 by a single, ambitious and prestige seeking individual working with a dictatorial government, is a clear case of cargo cult, an implicit desire to import industralized countries' science and technology by purchasing key in hand their expensive machine. The reactor has never ceased to experience difficulties since then, not so much of a physical or mechanical, but rather of a human nature and due to the almost grotesque distance between the machine's potentialities and the quantity and quality of personnel available. Demand and motivation have been scarce, because fossil and hydro energy have been so far plentiful. Military motivation was in theory absent. Perspectives have apparently improved, not that a scientific community has been trained and an infrastructure exists. Radioactive isotopes have been widely used in Venezuela, beginning in 1953, for medical practice and biological research. At present about 2.5 million bolivars worth of radioisotopes are imported annually, mostly from the US and to a lesser extent, from UK. Steps are being taken to train nuclear engineers, since most studies thus far indicate the last few years of the century as the time when nuclear energy will begin to enter the picture, and since a period of at least ten years is needed between the decision to build an atomic power plant and the time it goes into operation. Choice of technique has not been made, but an active, although still small, uranium prospecting program has been initiated. It seems as if, by the end of the century, either nuclear energy will have to supplement other sources, or standard of living of Venezuelans - at least that relative minority who can afford to live well - will drop. 2 figures, 2 tables.

  3. Applicability and optimization of SAGD in eastern Venezuela reservoirs

    Pina R, J.A.; Bashbush, J.L.; Fernandez, E.A. [Schlumberger, Caracas (Venezuela)

    2008-10-15

    Steam-assisted gravity drainage (SAGD) is one of the most effective enhanced oil recovery (EOR) methods. In Venezuela, a significant amount of heavy oil in place has been mapped, but limited areas have been developed. Suitable EOR methods need to be applied to extend the productive life of these reservoirs and increase their recovery factors. This paper presented and described an evaluation and stepwise optimization process for a steam-assisted gravity drainage (SAGD) project using a representative sector model from a field with fluid and reservoir characteristics from an eastern Venezuela formation. The purpose of the study was to understand the impact of key parameters in the process specific to the selected area and to understand the effects on the recovery factor in these reservoirs, which have previously produced with primary recovery mechanisms. The paper discussed a sensitivity analysis that was performed using thermal simulation. Thermal simulation and pressure-volume-temperature (PVT) analysis were described. Parameters that were analyzed included vertical well spacing, injection steam rate, well flowing pressure, and horizontal length of the well pair. The paper also presented a brief analysis of the effect on oil recovery from the angle of dip in the reservoir and the orientation of the well pair with regard to the direction of dip. A comparison between two- and three- pseudocomponent model results was also provided. The authors recommended that economic analyses should accompany the final optimization sequence, to incorporate financial and technical considerations for the selection design of the SAGD pilot. 7 refs., 12 tabs., 18 figs.

  5. Urban movements and disempowerment in Perú and Venezuela Movimientos urbanos y desempoderamiento en Perú y Venezuela

    2010-11-01

    Full Text Available This paper addresses a core puzzle: why is continued citizen mobilization accompanied by growing disempowerment of those same citizens? Why do movements fail, leaders burn out and members disperse, and what are the implications of this organizational failure for demo¬cratic representation? Our consideration of the issues is rooted in a close examination of urban movements, mobilization, empowerment and disempowerment in the recent experience of Venezuela and Perú. The puzzle that concerns us is of course not limited to these two countries: it is common to all the Andean republics, and in different ways, to much recent experience of urban mobilization in Latin America and beyond. After a brief account of urban citizen move¬ments and politics in our two cases, we outline general reflections on the nature of empowerment and disempowerment, on the peculiar combination of strengths and weaknesses that mark many contemporary movements. A close examination of types of movements and their links with poli¬tical parties and protest follows. The character of city life is important here. We close with analysis of recent waves of urban mobilization in Perú (that sparked the ouster of president Alberto Fujimori and in Venezuela (both for and against president Hugo Chávez Frías, and with reflections on the likely future of empowerment and disempowerment for urban citizens and the implications of this perspective for democratic representationEste artículo plantea un puzzle principal: ¿por qué la movilización ciudadana continuada viene acompañada de un crecimiento del desempoderamiento de estos mismos ciudadanos? ¿Por qué los movimientos fracasan, los líderes se desgastan y los miembros se dispersan, y cuáles son las implicaciones del fracaso organizativo para la representación democrática? Nuestra consideración del asunto encuentra sus raíces en un profundo análisis de los movimientos urbanos, de la movilización, del empoderamiento y del

    Full Text Available O objetivo do artigo é analisar a emergência do problema do trabalho infantil no cultivo de tabaco em Agudo, desencadeado pela promulgação do Decreto n. 6.481/2008, que trata das piores formas de trabalho infantil. Os procedimentos metodológicos utilizados foram a revisão bibliográfica, pesquisa documental e um estudo de caso, realizado no município de Agudo, Rio Grande do Sul. No estudo de caso, procurou-se obter dados quantitativos e qualitativos, por meio de questionários e entrevistas abertas, dirigidos para 27 agricultores familiares fumicultores, com filhos com menos de 18 anos de idade. Os resultados da pesquisa indicam a existência de um confronto entre diferentes concepções sobre o trabalho da criança no âmbito da agricultura familiar. Os dispositivos legais, os termos de compromissos e os contratos de integração na cadeia produtiva do fumo proíbem o trabalho de menores de 18 anos, fundamentando-se nos princípios internacionais da garantia do pleno desenvolvimento das crianças. Na perspectiva das famílias, o trabalho das crianças é entendido como "ajuda", forma de socialização e formação dos herdeiros. Portanto, os pais não concordam que se trata de uma forma perversa de exploração do trabalho dos próprios filhos.The aim of this paper is to analyze the emergence of the child labor problem in tobacco growing in Agudo (Rio Grande do Sul state, triggered by the promulgation of Act 6.481/2008, which addresses the worst child labor conditions.

    Mijares-Urrutia, A; Celsa Señaris, J; Arends, A

    2000-01-01

    Only two species of the microteiid lizard genus Euspondylus (E. acutirostris and E. phelpsorum) had been reported from Venezuela. New records of the poorly known gymnophthalmid lizard Euspondylus acutirostris are reported extending its known range along the Coastal Range and Sierra de Aroa (north-central Venezuela) and Sierra de San Luis (northwestern Venezuela), all records occurring at the cloud forest above 1000 m. Seven body measurements were included and morphological variation is described based on at least 17 new specimens. Sexual dimorphism is determined in, at least, eight characteristics of size and squamation. Specimens were found in epiphytic bromeliads and the ground. The populations from Sierra de Aroa and Sierra de San Luis (only one specimen known from each locality), differ from those of the Coastal Range (supposedly the nominal population) in some morphological and coloration features, suggesting that the former two could represent different taxonomical entities. A new species of Euspondylus is described based on a female (taken within a bromeliad) from Cerro El Humo, Sucre, northeastern Venezuela. It differs from congeners mainly by having keeled scales on the limbs and a very acute snout.

    Full Text Available RESUMEN: Partiendo de la afirmación de Levine y Molina (2006, según la cual la calidad de la democracia depende del funcionamiento de los procesos mediante los cuales la población selecciona y controla sus gobernantes, en este trabajo se examina el caso venezolano, haciendo especial énfasis en el análisis de la dinámica electoral del período marcado por la presidencia de Chávez (1999-2006. Dicho examen nos lleva a concluir que el régimen sociopolítico venezolano actual puede ser caracterizado más adecuadamente como un «régimen autoritario electoral», más que como una democracia representativa convencional. Los rasgos autoritarios del gobierno venezolano actual explicarían la baja puntuación obtenida por Venezuela en los índices de Freedom House. Sin embargo, este examen también nos lleva a considerar la pertinencia de los supuestos de la calidad de la democracia en el contexto de un cambio de régimen que explícitamente se aleja de las aspiraciones e ideales que sustentan el concepto, dimensiones e indicadores de la calidad de la democracia propuestos.ABSTRACT: Taking off from the affirmation by Levine and Molina that «the quality of democracy depends on the operation of procedures whereby the population selects and controls its government», this article examines the dynamics of elections during the Presidency of Chávez, (1999-2006. This examination leads to the conclusion that the current regime is better characterized as «an autoritarian electoral regime» than as a conventional representative democracy. This re-definition explains the low scores obtained by Venezuela both in Freedom House. At the same time, this study throws light on the bases of democracy and of definitions of quality of democracy in a regime that explicitly rejects the very ideals and aspirations that underlie the definitions, dimensions and indicators of democracy itself.

El Joropo se caracteriza por un sistema de estructuras cristalizadas a lo largo de la historia a partir de canciones y danzas tradicionales que se erigieron en formas musicales, sirviendo como base para a variantes en la letra, o convirtiéndose en formas puramente instrumentales. El Joropo es una tradición que abarca casi la totalidad del territorio venezolano y al menos la cuarta parte del territorio colombiano. En Venezuela el Joropo es considerado el baile nacional por excelencia y existen tres tipos de Joropo clasificados por regiones con importantes variantes de instrumentación y estilo: el Joropo Oriental, el Joropo Central y el Joropo Llanero. Solamente el Joropo Llanero, extendido alrededor de la cuenca central del Orinoco, es común a Colombia y Venezuela, siendo el más difundido de todos, tanto por la amplia discografía y radiodifusión como por la abundancia de festivales, concursos y torneos que involucran a ambos países. Además es notable el auge y desarrollo urbano que ha tenido esta música en los últimos años en las respectivas capitales. Sus orígenes se remontan a las músicas ibéricas del Siglo XVII y XVIII, tales como el múltiple Fandango, las Folías, Peteneras, Jotas y Malagueñas andaluzas, sazonadas con la influencia de ocho siglos de dominación árabe y posteriormente transformadas en América con el mestizaje de elementos africanos e indígenas, bajo el sol abrasador de la Cuenca del Orinoco y la vastedad infinita de sus horizontes y llanuras. Los antecesores del Joropo incluyen la música de marineros y trovadores que llega en los galeones provenientes de España, transformándose en música arraigada en el suelo americano y dando lugar a

    Se presenta un mapa geologico digital de Venezuela sobre un fondo de relieve sombreado. Los datos geologicos e hidrologicos del norte del rio Orinoco proceden de la digitalizacion de mapas geologicos en papel a escala 1:500.000. Estos datos fueron integrados con el mapa geologico digital del Escudo de Guayana Venezolano, a su vez derivado de hojas en papel a escala 1:500.000. La informacion sobre los tipos de fallas mostrados en el mapa es igual que en las fuentes originales. Los poligonos geologicos fueron atribuidos por edad, litologia y nombre de la unidad siguiendo el Codigo geologico de Venezuela. Se incorporaron revisiones significativas de la geologia de la Cordillera de la Costa a partir de las nuevas hojas integradas a escala 1:25.000. Toda esta informacion geologico-estructural se sobrepuso a una imagen de relieve sombreado, producida por el procesamiento de los datos de radar interferometrico con 90 m (3 arcosegundos) de resolucion espacial obtenidos por la mision topografica de radar del transbordador espacial (SRTM). Las areas de la base de datos del SRTM carentes de informacion fueron llenadas por medio de la interpolacion de los datos de las celdas adyacentes. Para producir la imagen de relieve sombreado se uso una direccion de iluminacion de 315 deg con un angulo de 65 deg sobre el horizonte. La proyeccion usada en el mapa es conica equidistante, con latitudes de 4 y 9 deg norte como paralelos estandar y una longitud de 66 deg al oeste como meridiano central. Los datos en el mapa proceden primordialment de hojas a escala 1:500.000 y el producto esta preparado para una impresion optima en escala 1:750.000. Los usuarios pueden obtener ampliaciones mayores, sin embargo no se garantiza la precision del mapa a escalas mas detalladas. Especialmente en la region de Guayana, al sobreponer los mapas geologicos sobre la reciente imagen SRTM, se notan grandes discrepancias no sistematicas tanto en contactos como en fallas. Esto es debido a que los mapas

    Full Text Available La enfermedad cardiovascular es la principal causa de muerte a nivel mundial. De ella, el Infarto Agudo al Miocardio (IAM y el Accidente Cerebrovascular (AVC se encuentran fuertemente asociados a los cambios ambientales y sociales del último tiempo, tales como aumento de ingesta de comida rápida, sedentarismo, tabaquismo, entre otros. Algunos trastornos psiquiátricos que aparecen a corto y largo plazo posterior al evento coronario agudo tienen una implicancia directa en la morbimortalidad cardiovascular y global. De ellos, la depresión representa el trastorno psiquiátrico más frecuente, pudiendo encontrarse en 3 de cada 10 pacientes que tuvieron un IAM. La depresión aumenta las hospitalizaciones, disminuye la adherencia terapéutica y empeora el pronóstico cardiovascular a largo plazo.  La fisiopatología en lo anterior es explicada en parte por alteraciones en el eje neuroendocrino y la respuesta al estrés, mientras que otros fenómenos permanecen aún desconocidos. Dentro de otros trastornos psiquiátricos asociados a un IAM se encuentran el delirium, ansiedad y trastornos de la personalidad. En función de lo anterior, se hace necesaria la incorporación de un sistema continuo de monitoreo y apoyo en salud mental en este grupo de pacientes para mejorar tanto su pronóstico como la calidad de vida.

  11. Prevalence of Dyslipidemias in Three Regions in Venezuela: The VEMSOLS Study Results

    González-Rivas, Juan P.; Nieto-Martínez, Ramfis; Brajkovich, Imperia; Ugel, Eunice; Rísquez, Alejandro

    2018-01-01

    Background The prevalence of dyslipidemia in multiple regions of Venezuela is unknown. The Venezuelan Metabolic Syndrome, Obesity and Lifestyle Study (VEMSOLS) was undertaken to evaluate cardiometabolic risk factors in Venezuela. Objective To determine the prevalence of dyslipidemia in five populations from three regions of Venezuela. Methods During the years 2006 to 2010, 1320 subjects aged 20 years or older were selected by multistage stratified random sampling from all households in five municipalities from 3 regions of Venezuela: Lara State (Western region), Merida State (Andean region), and Capital District (Capital region). Anthropometric measurements and biochemical analysis were obtained from each participant. Dyslipidemia was defined according to the NCEP/ATPIII definitions. Results Mean age was 44.8 ± 0.39 years and 68.5% were females. The prevalence of lipids abnormalities related to the metabolic syndrome (low HDL-c [58.6%; 95% CI 54.9 - 62.1] and elevated triglycerides [39.7%; 36.1 - 43.2]) were the most prevalent lipid alterations, followed by atherogenic dyslipidemia (25.9%; 22.7 - 29.1), elevated LDL-c (23.3%; 20.2 - 26.4), hypercholesterolemia (22.2%; 19.2 - 25.2), and mix dyslipidemia (8.9%; 6.8 - 11.0). Dyslipidemia was more prevalent with increasing body mass index. Conclusion Dyslipidemias are prevalent cardiometabolic risk factors in Venezuela. Among these, a higher prevalence of low HDL is a condition also consistently reported in Latin America. PMID:29538522

    Hernández, Dalila; Rojas, Elina; Scorza, José Vicente; Jorquera, Alicia

    2006-10-01

    In Trujillo, Venezuela the prevalence for American tegumentary leishmaniasis (ATL) is 38 per 100,000 inhabitants. In a periurban, rural settlement of the capital city Trujillo, we studied the potential capability of the domestic dog (Canis familiaris) as a source of infection for Lutzomyia youngi, a phlebotomine sand fly species abundant in the study area and whose domestic vectorial activity has been proven. Dogs with dermal lesions suggestive of ATL and parasitological confirmation of infection, were selected for xenodiagnosis by allowing sylvatic phlebotomines from a ATL free area, to feed ad libitum over each animal's entire body surface. The insects' intestinal tracts were dissected 5 days after the blood meal in order to look for flagellate forms. When these were found, parasitological identification was performed by the multiplex-PCR technique. Four hundred and fifty five sand flies engorged over two dogs in three different assays; promastigotes were found in 4 (0.88%) of the specimens on only one occasion. PCR identified DNA of the Leishmania Viannia subgenus. The household dog has the potential of being a domestic risk factor in the ATL transmission cycle.

  13. Origin of ultramafic-hosted magnesite on Margarita Island, Venezuela

    Abu-Jaber, N. S.; Kimberley, M. M.

    1992-06-01

    Ultramafic-hosted deposits of magnesite (MgCO3) have been studied on Margarita Island, Venezuela, to elucidate the source of carbon and conditions of formation for this type of ore. Petrographic, mineralogic, and δ18O data indicate that magnesite precipitated on Margarita in near-surface environments at low P and T. δ13C ranges from -9 to -16‰ PDB within the magnesite and -8 to -10‰ PDB within some calcite and dolomite elsewhere on the island. The isotopically light dolomite fills karst and the calcite occurs as stock-work veins which resemble the magnesite deposits. These carbon isotopic ratios are consistent with a deep-seated source rather than an overlying source from a zone of surficial weathering. However, there is not much enrichment of precious metals and no enrichment of heavy rare-earth elements, as would be expected if the carbon had migrated upward as aqueous carbonate ions. The carbon probably has risen as a gaseous mixture of CO2 and CH4 which partially dissolved in near-surface water before leaching cations and precipitating as magnesite and other carbonates. The process probably is ongoing, given regional exhalation of carbonaceous gases.

  15. Intestinal Parasitic Infections among Pregnant Women in Venezuela

    2006-01-01

    Full Text Available Introduction. Intestinal parasitic infections, especially due to helminths, increase anemia in pregnant women. The results of this are low pregnancy weight gain and IUGR, followed by LBW, with its associated greater risks of infection and higher perinatal mortality rates. For these reasons, in the setting of no large previous studies in Venezuela about this problem, a national multicentric study was conducted. Methods. Pregnant women from nine states were studied, a prenatal evaluation with a coproparasitological study. Univariated and multivariated analyses were made to determine risk factors for intestinal parasitosis and related anemia. Results. During 19 months, 1038 pregnant women were included and evaluated. Intestinal parasitosis was evidenced in 73.9%: A lumbricoides 57.0%, T trichiura 36.0%, G lamblia 14.1%, E hystolitica 12.0%, N americanus 8.1%, E vermicularis 6.3%, S stercoralis 3.3%. Relative risk for anemia in those women with intestinal parasitosis was 2.56 ( P<.01 . Discussion. Intestinal parasitoses could be associated with conditions for development of anemia at pregnancy. These features reflect the need of routine coproparasitological study among pregnant women in rural and endemic zones for intestinal parasites. Further therapeutic and prophylactic protocols are needed. Additional research on pregnant intestinal parasitic infection impact on newborn health is also considered.

  16. International migration data: their problems and usefulness in Venezuela.

    Torrealba, R

    1987-01-01

    During the 1940s and 1950s Venezuela was an important destination for migrants from Southern Europe, a flow that disappeared almost entirely during the 1960s, to be replaced by border movements and the largely illegal migration of Colombians. The oil boom of the 1970s saw an increase of the latter, which may have subsided during the 1980s due to the more difficult economic conditions that have also led to significant emigration levels of Venezuelans and former immigrants. Methods of data collection systems that provide information on migrants include the National Population and Housing Census, the National Household Survey, migration surveys, arrival and departure statistics, registration systems operated by the Direccion General Sectorial de identificacion y Control de Extranjeros, the 1980 regularization drive, statistics gathered by the Ministry of Labor, and vital and civil registration statistics. The lack of effective coordination among the different government agencies gathering information and the administrative nature of the data collected give rise to problems of comparability. Mechanisms to publish and disseminate the data available are not well developed, so that researchers often have no access to potentially useful sources of information. Problems of timeliness in the publication of the most widely used information are also present, as is the large gap existing in data pertaining to emigration, be it of Venezuelan nationals or of immigrants leaving the country.

    2003-01-01

    Overweight and obesity are a public health problem worldwide affecting adults and children as well. The aim of this study was to assess overweight, lipid profile and cardiovascular risk ratios in 390 preschool children from low socio-economic level from Valencia, Venezuela. Nutritional anthropometric evaluation measured by body dimensions, and serum determination of cholesterol, triglycerides, HDL-cholesterol, LDL-cholesterol and cardiovascular risk factors, were determined. 95% of the children were in relative and critical poverty. 14.3% of undernutrition and 20.8% of overweight was found. Lipid profile was in normal range, with no significant differences by sex, but higher values for HDL-cholesterol and risk ratios were found in children aged 1 to 3.99 years. Even though no differences were found by nutritional status, overweight children had higher values for lipids, except HDL-cholesterol. 6.3% of overweight children had cholesterol > or =170 mg/dL, 16.5% LDL-cholesterol > or =110 mg/dL, 40.5% triglycerides > or =75mg/dL and 100% HDL-cholesterol <45 mg/dL. Overweight and lipid profile alterations were present in an important group of the children, which increase their risk of obesity and chronic non-transmissible diseases. Nutritional and educational intervention should be addressed.

  18. en la Venezuela de Chávez

    Alfredo Ramos Jiménez

    2011-01-01

    Full Text Available Bajo el liderazgo carismático y plebiscitario, el experimento bolivariano de Chávez y del chavismo en el poder se mueve entre el desgobierno y el autoritarismo. La relevancia de esta fórmula política, en la experiencia de Venezuela en los años recientes, ha sido observada, si no adoptada, en otras experiencias recientes en las democracias andinas, como una alternativa exitosa frente al denunciado fracaso de la democracia representativa. Con las banderas y símbolos de un bolivarianismo retórico, que se combina con un indeterminado “socialismo del siglo xxi”, se ha pretendido impulsar lo que se ha convenido en llamar “revolución bolivariana”. En este artículo me propongo como objetivo interpretar tal fenómeno a partir de los resultados de las elecciones y referendos después de la reelección de Chávez en diciembre de 2006.

  20. Geochemical record of anthropogenic impacts on Lake Valencia, Venezuela

    Xu Yunping; Jaffe, Rudolf

    2009-01-01

    Bulk geochemical parameters and organic matter biomarkers in a short, high resolution gravity core (Lake Valencia, Venezuela) were examined to reconstruct anthropogenic impacts on the lake's conditions. During the period of ca. 1840-1990, sedimentary organic matter was characterized by high contents of total organic C (TOC) and total N (TN), low TOC/TN values as well as relatively enriched δ 13 C and δ 15 N signals, suggesting a primary autochthonous (algae and macrophytes) organic matter origin. The occurrence of large amounts of C 23 and C 25 relative to C 29 and C 31 n-alkanes indicated substantial inputs from submerged/floating macrophytes. The variations of C 32 15-keto-ol, tetrahymanol, diploptene, C 32 bishomohopanol, 2-methylhopane, dinosterol and isoarborinol concentrations over the investigated period record changes in the planktonic community structure, including Botryococcus braunii, bacteriavore ciliates, cyanobacteria, Eustigmatophytes and dinoflagellates. A principal shift occurred in the 1910s when cyanobacteria and dinoflagellates became more abundant at the expense and decline of B. braunii and Eustigmatophytes, likely related to increasing anthropogenic activity around the lake. A second shift (less obvious) occurred in the 1960s when cyanobacteria became the sole predominant planktonic class, coinciding with further deterioration of lake conditions

  1. Venezuela's Barrio Adentro: an alternative to neoliberalism in health care.

    Muntaner, Carles; Salazar, René M Guerra; Benach, Joan; Armada, Francisco

    2006-01-01

    Throughout the 1990s, all Latin American countries but Cuba implemented health care sector reforms based on a neoliberal paradigm that redefined health care less as a social right and more as a market commodity. These reforms were couched in the broader structural adjustment of Latin American welfare states as prescribed by international financial institutions since the mid-1980s. However, since 2003, Venezuela has been developing an alternative to this neoliberal trend through its health care reform program, Misión Barrio Adentro (Inside the Neighborhood). In this article, the authors review the main features of the Venezuelan health care reform, analyzing, within their broader sociopolitical and economic contexts, previous neoliberal health care reforms that mainly benefited transnational capital and domestic Latin American elites. They explain the emergence of the new health care program, Misión Barrio Adentro, examining its historical, social, and political underpinnings and the central role played by popular resistance to neoliberalism. This program not only provides a compelling model of health care reform for other low- to middle-income countries but also offers policy lessons to wealthy countries.

  3. Chavism and Criminal Policy in Venezuela, 1999-2014

    Martha Lia Grajales

    2017-03-01

    Full Text Available For a long time, the Venezuelan democracy was an exception in South America due to a party system that was based on what was known as the ‘Punto Fijo Pact’. At the start of the 1980s a series of economic, social and political events began to occur, which caused this ‘exceptionalism’ to stagger and disrupt the institutionality of the traditional Venezuelan democratic State. The events led to a deep national crisis and the birth of a new political era. By the end of the 1990s, there had been a significant shift towards left-wing governance. Hugo Chávez Frías subsequently won the presidential elections in 1998. This paper analyzes some aspects of the criminal policies that were implemented during the reign of left-wing leader Chávez till his death in 2013 and thereafter by Chavist party president elect, Nicolás Maduro during 2013-2014. Four stages can be identified in the behavior of incarceration rates. The first stage, from 1999 to 2000, was characterized by the lowest recordings of incarceration rates and the lowest measured percentage of preventive detention in Venezuela in thirty years. The second stage, from 2001 to 2005, saw a slight increase in the incarceration rate which then remained stable. The third stage, from 2006 to 2012, and the fourth stage, from 2013 to 2014, are characterized by sustained increases in preventive detention, incarceration and murder rates.

  4. Anatomy of 31 species from Mimosoideae (Leguminosae) subfamily on Venezuela

    Leon, H; Williams, J.

    2008-01-01

    This paper is about the wood anatomy of 31 species, belonging to 17 genera, of the Mimosoideae subfamily (Leguminosae), proceeding from different geographical regions of Venezuela. For each species, one to five individuals were studied. The descriptions were realized according to the IAWA Committee(1989). The studied species may be divided in two groups according to the presence or absence of septate fibers. All species of Inga showed septate fibers, whereas Albizia and Enterolobium included species with septate fibers and also species with non-septate fibers. The quantitative characteristics of the vessels and the width of rays showed sufficient variation as to be considered important characteristics from ataxonomic point of view. The most common parenchyma type was vasicetric, aliform and confluent. In Calliandra laxa, Prosopis juliflora and Zygia longifolia the main parenchyma type was in wide bands; whereas in Cedrelinga cateniformis, the main parenchyma type was thin vasicentric. All species studied, with the exception of Cedrelinga cateniformis, presented prismatic crystals in the parenchymatous axials cells. In spite of finding certain anatomical uniformity, it was possible to elaborate a key for the identification of the studied species.

  5. Integrality in Brazil and Venezuela: similarities and complementarities.

    Santos, Carla Targino Bruno Dos; Barros, Ione Silva; Amorim, Anne Caroline Coelho Leal Árias; Rocha, Dais Gonçalves; Mendonça, Ana Valéria Machado; Sousa, Maria Fátima de

    2018-04-01

    This study aims to compare Primary Health Care (PHC) in Brazil and Venezuela, considering its characteristics as to integrality. It has a qualitative approach, using documental analysis, semi-structured interviews with key informants and field diary notes. We observed the three realms of integrality inherent to the health work process: comprehensive and holistic care, the individual viewed as a complex being with multiple needs, requiring the connection of various health knowledge; continuity of care in institutional micro-policy with interprofessional articulation, in order to consider individual care; continuity of care in macro-policy, when a shift to other levels of care is needed; intersectoriality was also included, when the needs of an individual and community require a cross-sectoral coordination, with action on determinants and conditionants of the health-disease process. It is worth highlighting the natural tendency to include a comprehensive community medical training. We conclude that those countries strengthened by democracy draw their integrality practices closer, as well as the construction of social and health policies for underprivileged populations to achieve equity.

  6. Seroprevalence of Toxocara canis infection in tropical Venezuela.

    Lynch, N R; Eddy, K; Hodgen, A N; Lopez, R I; Turner, K J

    1988-01-01

    An enzyme-linked immunosorbent assay (ELISA) was used to determine the seroprevalence of Toxocara canis infection in different socio-economic groups of the tropical population of Venezuela. The lack of definitive independent diagnostic criteria for toxocariasis required the establishment of operational upper limits of normality for Toxocara ELISA values, based upon their log-normalized distribution in a presumptive "non-toxocariasis" sub-population. Only 1.8% of urban subjects of medium-high socio-economic level were considered to be clearly positive in Toxocara ELISA, compared to 20.0% of urban slum dwellers, 25.6% rural subsistence farmers and 34.9% Amazon Indians. As the test was performed using excretory-secretory antigen, and under conditions of competitive inhibition by soluble extracts of non-homologous parasites, co-infection by common intestinal helminths, protozoa or other organisms did not give rise to false positive results. However, strong cross-reactivity with Onchocerca volvulus may have influenced the prevalence figure obtained for the Amazon Indians. These results indicate that T. canis is yet another parasite that is widely distributed in economically underprivileged tropical populations.

    Introduction. Intestinal parasitic infections, especially due to helminths, increase anemia in pregnant women. The results of this are low pregnancy weight gain and IUGR, followed by LBW, with its associated greater risks of infection and higher perinatal mortality rates. For these reasons, in the setting of no large previous studies in Venezuela about this problem, a national multicentric study was conducted. Methods. Pregnant women from nine states were studied, a prenatal evaluation with a coproparasitological study. Univariated and multivariated analyses were made to determine risk factors for intestinal parasitosis and related anemia. Results. During 19 months, 1038 pregnant women were included and evaluated. Intestinal parasitosis was evidenced in 73.9%: A lumbricoides 57.0%, T trichiura 36.0%, G lamblia 14.1%, E hystolitica 12.0%, N americanus 8.1%, E vermicularis 6.3%, S stercoralis 3.3%. Relative risk for anemia in those women with intestinal parasitosis was 2.56 (P Intestinal parasitoses could be associated with conditions for development of anemia at pregnancy. These features reflect the need of routine coproparasitological study among pregnant women in rural and endemic zones for intestinal parasites. Further therapeutic and prophylactic protocols are needed. Additional research on pregnant intestinal parasitic infection impact on newborn health is also considered. PMID:17093349

  13. Susceptibility status of Aedes aegypti (L.) (Diptera: Culicidae) to temephos in Venezuela.

    Alvarez, Leslie C; Ponce, Gustavo; Oviedo, Milagros; Lopez, Beatriz; Flores, Adriana E

    2014-08-01

    Temephos is an insecticide widely used in Venezuela to control the proliferation of the larvae of Aedes aegypti (L.), the principal vector of dengue virus. The aim of this study was to identify the susceptibility to temephos of Ae. aegypti in four locations in western Venezuela: Lara, Tres Esquinas, Ureña and Pampanito. Larval bioassays were conducted on samples collected in 2008 and 2010, and the levels of α- and β-esterases, mixed-function oxidases, glutathione-S-transferase and insensitive acethyl cholinesterase were determined. Larval populations from western Venezuela obtained during 2008 and 2010 were found to be susceptible to temephos, with low resistance ratios and without overexpression of enzymes. The low RR values reveal the effectiveness of temephos in controlling the larval populations of Ae. aegypti. Control strategies must be vigorously monitored to maintain the susceptibility to temephos of these populations of Ae. aegypti. © 2013 Society of Chemical Industry.

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

    1985-01-01

    A report has recently been published which describes the findings of the International Uranium Resources Evaluation Project (IUREP) mission to Venezuela. The IUREP Orientation Phase mission to Venezuela estimates that the Speculative Resources of that country fall within the range 2,000 to 42,000 tonnes uranium.- The majority of this potential is expected to be located in the Precambrian crystalline and sedimentary rocks of the Guayana Shield. Other potentially favorable geologic environments include Cretaceous phosphorite beds, continental sandstone and granitic rocks. The mission recommends that approximately US $18 million be spent on exploration in Venezuela over the next five years. The majority of this expenditure would be for surface surveys utilizing geologic studies, radiometric and geochemical surveys and some drilling for geologic information. Additional drilling would be required later to substantiate preliminary findings. (author)

    Full Text Available AS ZONAS fronteiriças são zonas de empréstimos e apropriações culturais e, por isso, um lugar privilegiado para a compreensão do fenômeno migratório internacional. O objetivo deste trabalho é apresentar alguns aspectos do processo de deslocamentos transfronteiriços no norte do Brasil, no município de Pacaraima (Estado de Roraima e na fronteira sul da Venezuela, no município de Gran Sabana (Estado Bolívar, e, ao mesmo tempo, apontar as tendências e reflexos nas configurações socioculturais nessas zonas de contato. Nessa fronteira Brasil-Venezuela, podemos afirmar que o trânsito maior é de brasileiros para a Venezuela e para a Guiana, em decorrência das possibilidades de atuarem nas atividades de mineração, no comércio local e no setor de transportes, além das atividades ilegais, como tráfico de mulheres, contrabando de combustível e câmbio ilegal de moeda. Apresenta-se, no entanto, uma nova tendência que é a imigração de estrangeiros de outros países do continente, tais como peruanos e colombianos. Esses migrantes transfronteiriços percorrem os países fronteiriços em itinerários cuja porta de entrada é a Venezuela e a Guiana, mas também o Estado do Amazonas.BORDER zones are zones of cultural lending, borrowing and appropriation, and, therefore, a privileged vantage point for understanding the phenomenon of international migration. This essay attempts to examine certain aspects of the transborder dislocation process in northern Brazil (the city of Pacaraima, state of Roraima and in southern Venezuela (the city of Gran Sabana, state of Bolívar, and point out its trends and reflections on the sociocultural makeup of those contact zones. In this Brazil-Venezuela border, the largest movement is clearly that of Brazilians going into Venezuela and Guyana in search of job opportunities in mining, local business and transportation, not to mention illegal activities such as the traffic of women, fuel smuggling and

    2017-08-01

    Wild plants of the family Convolvulaceae are hosts for a few New World begomoviruses (genus Begomovirus, family Geminiviridae). In this work, we report the complete genome sequence of a new begomovirus infecting the wild convolvulaceous plant Jacquemontia tamnifolia in Venezuela. The cloned bipartite genome showed the organization of typical New World begomoviruses and was found to be phylogenetically related to those of begomoviruses from Venezuela and other Caribbean countries. Several recombination events have been shown to have occurred involving genome fragment exchange with related begomoviruses infecting crops such as tomato and cucurbits and wild plants, including Jacquemontia sp. We propose the name jacquemontia yellow vein virus (JacYVV) for this new begomovirus.

  7. STSHV a teleinformatic system for historic seismology in Venezuela

    Choy, J. E.; Palme, C.; Altez, R.; Aranguren, R.; Guada, C.; Silva, J.

    2013-05-01

    From 1997 on, when the first "Jornadas Venezolanas de Sismicidad Historica" took place, a big interest awoke in Venezuela to organize the available information related to historic earthquakes. At that moment only existed one published historic earthquake catalogue, that from Centeno Grau published the first time in 1949. That catalogue had no references about the sources of information. Other catalogues existed but they were internal reports for the petroleum companies and therefore difficult to access. In 2000 Grases et al reedited the Centeno-Grau catalogue, it ended up in a new, very complete catalogue with all the sources well referenced and updated. The next step to organize historic seismicity data was, from 2004 to 2008, the creation of the STSHV (Sistema de teleinformacion de Sismologia Historica Venezolana, http://sismicidad.hacer.ula.ve ). The idea was to bring together all information about destructive historic earthquakes in Venezuela in one place in the internet so it could be accessed easily by a widespread public. There are two ways to access the system. The first one, selecting an earthquake or a list of earthquakes, and the second one, selecting an information source or a list of sources. For each earthquake there is a summary of general information and additional materials: a list with the source parameters published by different authors, a list with intensities assessed by different authors, a list of information sources, a short text summarizing the historic situation at the time of the earthquake and a list of pictures if available. There are searching facilities for the seismic events and dynamic maps can be created. The information sources are classified in: books, handwritten documents, transcription of handwritten documents, documents published in books, journals and congress memories, newspapers, seismologic catalogues and electronic sources. There are facilities to find specific documents or lists of documents with common characteristics

  8. [Changes in lipid availability in Venezuela, 1970-1992].

    Abreu Olivo, E A; Ablan de Flórez, E

    1994-12-01

    The authors carry out a research focused on the quantification and analysis of the main changes in feeding and nutrition in Venezuela between 1970 and 1992. Such research started with the review and adjustment of the Food Balance Sheets (Hojas de Balance de Alimentos) elaborated by the Instituto Nacional de Nutrición (National Nutrition Institute) between 1970 and 1979 in order to homogenize them in a methodological way to make them similar to those elaborated by that institution and the Fundación Polar for the 1980-90 period. Estimates were made about the daily and per person availability of food for human consumption (DCH) for 1991 and 1992. This report, a partial product of that research, characterizes the evolution of the lipidic DCH in Venezuela for the 1970-1992 period. This period has been divided in seven stages of the evolution of the total energetic DCH, as this reflects well the course of the daily and per person Food Purchasing Power (PCA); there is a direct and strong functional relationship between these two variables. Along those stages the behaviour of the lipidic DCH is studied and we try to view possible relationships between the evolution of the Venezeluans economical situation and the absolute and relative variations observed in the level and the structure of the lipidic DCH. This structure is analyzed from several points of view: groups of food sources, origin, "visibility", and place of origin. One purpose is to determine also which food groups are mainly responsible for the venezuelan's external lipidic dependence. A general picture of the evolution of the DCH for saturated fatty acids and cholesterol is made, as well as of the variations experienced by the P/S and M/S relationships. It was found that the most dynamic elements, those that can explain a very high percentage of the variations observed in the level and the structure of the lipidic DCH were: the groups of foods of Visible Fats, Milk and dairy products, and Meats; vegetal lipids

    Full Text Available Se realizó un estudio epidemiológico descriptivo de corte transversal, con el objetivo de determinar la morbilidad oculta por parasitismo intestinal en Lagunita, municipio Girardot, Venezuela; en el período de enero a octubre de 2009. El universo fue de 286 niños, lo que se corresponde con la población total del grupo de edad de menores de 15 años. De estos se seleccionaron por muestreo aleatorio simple 43 pacientes, a los que se les aplicó un cuestionario y se confeccionó una guía de observación, para describir los factores epidemiológicos que influyen en la infestación por parasitismo intestinal. Además, se les realizaron análisis de las heces fecales seriadas para el diagnóstico del parasitismo. El método estadístico fue el cálculo de las frecuencias absolutas y relativas. A través del estudio de las heces fecales seriadas se obtuvo que 27 pacientes tenían parasitosis intestinal, para una morbilidad de 62,79%, con una mayor incidencia en los niños de cinco a nueve años de edad. El sexo femenino fue el más afectado. Los factores epidemiológicos que más influyeron fueron: los malos hábitos higiénicos personales, el entorno desfavorable y el consumo de agua no potable; existió relación entre el nivel socioeconómico, los factores epidemiológicos y la morbilidad por parasitismo intestinal. Predominó la parasitosis por Entamoeba Histolytica, con 11 casos, para un 40,74%. La diarrea, las molestias abdominales y la pérdida de apetito constituyeron los principales síntomas

  11. Cambios institucionales: La descentralización en Venezuela

    José Ramírez

    2002-01-01

    Full Text Available Este artículo presenta un esbozo de un conjunto de hechos históricos ocurridos en el transcurrir de los siglos XIX y XX, concebidos como antecedentes de la descentralización en Venezuela. Esos acontecimientos son interpretados y analizados dentro del amplio contexto político de la organización y consolidación del Estado desde los inicios de la República en el siglo XIX hasta la creación de la Comisión Presidencial para la Reforma del Estado (COPRE en 1984. Se parte de una noción sobre las bases teóricas de esas estrategias del desarrollo, se busca el vínculo a lo largo del proceso histórico republicano desde los tiempos del federalismo en adelante, se hace un diagnóstico e interpretación de la regionalización, y se aborda el origen de la descentralización y sus objetivos. A modo de conclusión se reafirma la apreciación teórica y metodológica de esas propuestas para el desarrollo, se insiste en su indisoluble unión a lo histórico, se deslinda el momento de inicio de la aceleración del crecimiento económico a partir de la regionalización, y se ratifica la descentralización como propuesta política para la modernización de la democracia partidista de finales del siglo XX.

  2. Abdome agudo em pós-operatório tardio de apendicite aguda: pode não ser bridas

    Bruno Castro Fernandes

    2014-10-01

    Full Text Available As ressecções intestinais em países desenvolvidos ocorrem devido às malformações congênitas. Em países em desenvolvimento essas resseções ocorrem por causas potencialmente evitáveis, como invaginação intestinal irredutível, trauma abdominal fechado, volvo de jejuno-íleo, enterocolite necrosante, hérnia inguinal estrangulada e obstrução por bridas pós-operatórias. O volvo intestinal na infância é raro e geralmente de causas iatrogênicas causado, por exemplo, pela presença de grampos soltos a cavidade intestinal após apendicectomia laparoscópica. O volvo de jejuno-íleo pode ser secundário à isquemia nos casos de gastrosquise tratadas com silo ou mesmo pela colocação de banda gástrica pós-laparoscopia, ou ainda pela presença de lipoma mesentérico. Não foi identificado trabalho na literatura recente sobre volvo jejuno-íleo e isquemia e necrose de segmento de alça intestinal. O autores relatam um caso de abdome agudo obstrutivo em criança de 6 anos, em pós-operatório tardio (4 anos de apendicectomia aberta e cuja ressecção de segmento de Alça intestinal foi necessária nas duas oportunidades mas por motivos diferentes. Situações adversas em abdome agudo pós-operatório podem não ser por aderências intestinais, mas por situações mais graves e o cirurgião deve estar preparado para corrigir sua tática operatória.

  6. Streptomyces venezuelae TX-TL - a next generation cell-free synthetic biology tool.

    Moore, Simon J; Lai, Hung-En; Needham, Hannah; Polizzi, Karen M; Freemont, Paul S

    2017-04-01

    Streptomyces venezuelae is a promising chassis in synthetic biology for fine chemical and secondary metabolite pathway engineering. The potential of S. venezuelae could be further realized by expanding its capability with the introduction of its own in vitro transcription-translation (TX-TL) system. TX-TL is a fast and expanding technology for bottom-up design of complex gene expression tools, biosensors and protein manufacturing. Herein, we introduce a S. venezuelae TX-TL platform by reporting a streamlined protocol for cell-extract preparation, demonstrating high-yield synthesis of a codon-optimized sfGFP reporter and the prototyping of a synthetic tetracycline-inducible promoter in S. venezuelae TX-TL based on the tetO-TetR repressor system. The aim of this system is to provide a host for the homologous production of exotic enzymes from Actinobacteria secondary metabolism in vitro. As an example, the authors demonstrate the soluble synthesis of a selection of enzymes (12-70 kDa) from the Streptomyces rimosus oxytetracycline pathway. © 2017 The Authors.

  14. Geographic distribution and host plants of Raoiella indica and associated mite species in northern Venezuela.

    Vásquez, Carlos; de Moraes, Gilberto J

    2013-05-01

    The red palm mite (RPM), Raoiella indica Hirst (Acari: Tenuipalpidae), is an invasive pest in the New World, where it is currently considered a serious threat to coconut and banana crops. It was first reported from northern Venezuela in 2007. To determine its current distribution in this country, surveys were carried out from October 2008 to April 2010 on coconut (Cocos nucifera L.), banana (Musa spp.), ornamental plants and weeds in northern Venezuela. Higher population levels of RPM were registered on commercial coconut farms in Falcón and Sucre states but also on other plant species naturally growing along the coastal line in Anzoategui, Aragua, Carabobo, Monagas and Nueva Esparta states. Out of 34 botanical species evaluated, all RPM stages were observed only on eight arecaceous, one musaceous and one streliziaceous species, indicating that the pest developed and reproduced only on these plants. Mite specimens found on weeds were considered spurious events, as immature stages of the pest were never found on these. Amblyseius largoensis (Muma) (Acari: Phytoseiidae) was the most frequent predatory mite associated with RPM in all sampling sites. The results indicate that RPM has spread to extensive areas of northern Venezuela since its initial detection in Güiria, Sucre state. Considering the report of this pest mite in northern Brazil in the late 2009, additional samplings in southern Venezuela should be carried out, to evaluate the possible presence of RPM also in that region.
