    Several species of microsporidia and coccidia are protozoa parasites responsible for cholan-giopathy disease in patients infected with human immunodeficiency virus (HIV). The goals of this work were to identift opportunistic protozoa by molecular methods and describe the clinical manifestations at the gastrointestinal tract and the biliary system in patients with AIDS-associated cholangiopathy from Buenos Aires, Argentina. This study included 11 adult HIV-infected individuals with diagnosis ofAIDS- associated cholangiopathy. An upper gastrointestinal endoscopy with biopsy specimen collection and a stool analysis for parasites were performed on each patient. The ultrasound analysis revealed bile ducts compromise. An endoscopic retrograde cholangiopancreatography and a magnetic resonance cholangiography were carried out. The identification to the species level was performed on biopsy specimens by molecular methods. Microorganisms were identified in 10 cases. The diagnosis in patients with sclerosing cholangitis was cryptosporidiosis in 3 cases, cystoisosporosis in 1 and microsporidiosis in 1. In patients with sclerosing cholangitis and papillary stenosis the diagnosis was microsporidiosis in 2 cases, cryptosporidiosis in 2 and cryptosporidiosis associated with microsporidiosis in 1. In 3 cases with cryptosporidiosis the species was Cryptosporidium hominis, 1 of them was associated with Enterocytozoon bieneusi, and the other 2 were coinfected with Cryptosporidium parvum. In the 4 cases with microsporidiosis the species was Enterocytozoon bieneusi. These results suggest that molecular methods may be useful tools to identify emerging protozoa in patients with AIDS-associated cholangiopathy.

    Historic time series (1970-2006) emissions of greenhouse gases and air pollutants arising from stationary and mobile combustion sources were estimated at national level for Argentina and at regional level for the metropolitan area of Buenos Aires (MABA). All emissions were estimated using a bottom-up approach following the IPCC good practice guidance. For mobile sources, national emissions include all transport categories. Regional emissions account thus far only for on-road. For national emissions, methodologies and guidance by the IPCC were employed, applying the highest possible tier and using: i)country-specific emission factors for carbon and sulphur and technology-based information for other species, ii)activity data from energy balance series (1970-2007), and iii)complementary information concerning the non-energy use of fuels. Regional emissions in 2006 were estimated in-depth using a technology-based approach for the city of Buenos Aires (CBA) and the 24 neighboring districts composing the MABA. A regional emissions factors database was developed to better characterize Latin American fleets and driving conditions employing COPERT III-IV algorithms and emission factors measured in dynamometers and circulating vehicles in Argentina, Brazil, Chile and Colombia. Past emissions were back estimated from 2005 to 1970 using the best available information, which differs greatly among categories, spatial disaggregation and time periods. The time series of stationary and mobile combustion sources at the national and regional level allowed the identification of distinct patterns. National greenhouse gas emissions in 2006 amounted to ~ 150 million ton CO2-equivalent, 70% of which were contributed by stationary sources. On-road transport was the major contributor within mobile sources (28.1 %). The increasing emissions trends are dominated by on-road transport, agriculture and residential categories while the variability is largely associated with energy industries

    Mycobacterioses can produce nonspecific clinical signs in dogs and cats that make diagnosis difficult. Furthermore, the full characterization of mycobacterial agents is not always possible or practical. We characterized mycobacteria detected through cytology in 12 dogs and 7 cats with generalized clinical signs from the province of Buenos Aires in Argentina. In dogs, molecular testing confirmed the presence of Mycobacterium avium subsp. hominissuis (MAH) in 8 cases and M. fortuitum in 1 case. All dogs were Miniature Schnauzers, suggesting that this breed may be more susceptible to M. avium than other dog breeds. The cat isolates were 2 M. bovis, 1 M. fortuitum, and 1 MAH. Mycobacterial interspersed repetitive unit-variable-number tandem repeat patterns suggested possible links with cattle, swine, and humans studied previously in Argentina. The results show that pets may act as susceptible hosts with the potential risk of transmitting the infection to humans and other animals.

    Due to low population density, total air pollutant emissions in Argentina are still low if compared with highly industrialised countries. Although a significant deterioration of air quality has been observed for a long time, air monitoring did not begin until the 90's and only in a few cities. The use of air pollution biomonitors represents an important contribution to Argentina, as measurements of air pollutants in large areas would require especial technical equipment not easily available and operated. In this project, two lichen species (Ramalina ecklonii (Spreng) Mey and Flot and Usnea amblyoclada (Muell. Rg.) Zahlbr.) and a Bromeliaceae (Tillandsia capillaris) are used as biomonitors of air pollution at a 50, 000 km 2 area in Cordoba province (central Argentina). AAS and INAA have been applied for the analysis of samples, determining As, Ba, Br, Ce, Co, Cr, Cs, Cu, Eu, Fe, Hf, Gd, K, La, Lu, Mn, Na, Ni, Pb, Rb, Sb, Sc, Sm, Ta, Tb, Th, U, Yb and Zn. The following physiological parameters were also determined: chlorophyll a, chloropyll b, phaeophytin a, phaeophytin b, hydroperoxy conjugated dienes, malonaldehide and sulphur. Some of these parameters were used for calculating a pollution index. These determinations were carried out on pools collected at the sampling sites. AAS and physiological parameters were also applied to the analysis of five-replicate samples in order to study variability sources. For data evaluation, different statistical and other evaluating tools were used: descriptive statistics and Spearman's correlation analysis were used on data from the three biomonitor species while factor analysis and mapping, only for R. ecklonii results.

    Full Text Available This paper is about the representations, practices and cultural expressions carried out by groups of Bolivian immigrants and their descendants in the cities of Olavarria, Tandil and Azul in the province of Buenos Aires, Argentina. For this purpose, the three case studies presented are analyzed based on the theoretical notions of identities and ethnic groups proper to the field of social anthropology. It thus seeks to contribute to knowledge about the construction of the identities of Bolivian immigrants in Argentina and, especially, to the discussion of those perspectives that propose the cultural assimilation of these groups into the host society.

    Claudia Irene Menghi

    Full Text Available Hydatidosis is a parasitic infection caused by the tapeworm larva of Echinococcus spp. Its relevance lies in its wide distribution, great number of clinical cases and outstanding morbility. Hydatid infection of the orbit comprises far less than 1% of the total incidence. This is a case of a patient from Argentina complaining of a two-week evolution proptosis of the right eye. A microscopic examination revealed the presence of protoscolices of Echinococcus spp. in the fluid obtained during the surgical proceedings. The patient was treated with oral albendazole. To our knowledge, this is the first case of occular hydatidosis diagnosed in the city of Buenos Aires, Argentina.

    A cross-sectional study was carried out on cats attending the Small Animal Hospital at the Faculty of Veterinary Sciences of the University of Buenos Aires to assess the prevalence and associated risk factors of Feline immunodeficiency virus (FIV) and Feline leukemia virus (FeLV) in the city of Buenos Aires, Argentina. Blood samples from 255 cats with symptoms compatible with FIV or FeLV infection, collected between 2009 and 2013 were analyzed by serology (immunochromatography, IA) and by hemi-nested PCR (n-PCR). The IA and n-PCR assays showed similar percentages of positivity for FIV while the n-PCR test was more sensitive for FeLV. Differences between the diagnostic tests and their choice according to the age of the animal are discussed. The clinical histories of ninety of the 255 cats showed blood profiles similar to others previously reported and revealed a higher risk of infection in male adult cats with outdoor access.

    Full Text Available The blueberry, Vaccinium corymbosum L. (Ericaceae, is a shrub native to the northern Hemisphere introduced in Argentina, where it occupies small cultivated areas mainly in the provinces of Buenos Aires, Entre Ríos and Tucumán. At present, little is known about insects associated with this crop in Argentina. The aim of this study was to identify the species of Chrysomelidae present in blueberry crops in different regions of Argentina, and to present new chrysomelids-blueberry associations. Identification diagnosis, geographical distribution, association with other plants and aspects of their biology is given for each species. Seven species of crop-damaging Chrysomelidae were recorded in blueberry crops of Buenos Aires and Entre Rios. They belong to the subfamilies Galerucinae: Diabrotica speciosa (Germar, Disonychodes exclamationis (Boheman, Caeporis stigmula Germar, and Cacoscelis melanoptera Germar; Eumolpinae: Percolaspis varia (Lefèvre, and Spintherophyta semiaurata (Klug; and Cryptocephalinae: Lexiphanes coenobita Suffrian.El arándano, Vaccinium corymbosum L.

    The study of carrion fauna associated with buried human corpses from a forensic perspective could provide useful information in criminal investigations. Insects and other arthropods remains sampled of 44 legally exhumed infant skeletons from La Plata (Buenos Aires, Argentina). They were identified at different taxonomic levels depending on the state of preservation. The specific diversity, abundance and frequency were analyzed and each taxon was assigned to the hypothetical colonization sequence: burial colonization, post-exhumation contamination at cemetery deposit or soil fauna. The phorid Dohrniphora sp. is mentioned for the first time in Argentina as carrion fauna of underground colonization, and the assemblage of Dohrniphora sp., Megaselia scalaris and Hydrotaea aenescens is proposed as indicator of buried cadavers. These findings provide new useful data to be applied in forensic entomology research. Copyright © 2017 Elsevier Ltd and Faculty of Forensic and Legal Medicine. All rights reserved.

    2011-01-01

    Included within the field of research on changes in drug use patterns and vulnerability are conditions of emergency related to economic crisis, wars, and political conflict. This study addresses the complex connections between the rapid propagation of freebase cocaine (FBC)-locally known as "pasta base" or "Paco" in Argentina and the normalization of the consequences of Argentina's 2001-2002 political-economic crisis. On the basis of the results of an ethnographic study carried out in three neighborhoods of the Greater Buenos Aires area between 2001 and 2005, this article aims to analyze how changes in the material and social living conditions are interrelated with the high toxicity of FBC/Paco and engender the emerging compulsion of its consumption and deterioration to the bodies, subjectivities, and social activities of active drug users from these shantytowns. By analyzing the changes in transactions directly or indirectly involving drugs-specifically those ranging from cocaine to FBC/Paco-we can argue how structural poverty, "new poverty," is not only associated with the expansion of FBC/Paco but is also shaped by its use, modes of consumption, associated health problems, and sufferings.

    This qualitative study of low-income mothers in Buenos Aires, Argentina, examines the influence of socio-economic conditions, organizational structures, family relationships, and food insecurity on child feeding practices and weight status. Thirty-eight mothers of preschool children living in urban Buenos Aires participated in four focus group discussions. The results indicated that many mothers were aware that obesity may be detrimental to the child's health, but most of them are unclear about the specific consequences. Maternal employment, family pressures, food insecurity and financial worries seem to influence child feeding practices. These findings have important implications for developing strategies for nutritional assistance that could benefit the health of children and provide opportunities for educational programs that are directed to nutritional awareness in Buenos Aires, Argentina. The right to eat regularly and properly is an obligation of the State and must be implemented taking into account the notion of food sovereignty and respecting the importance of preserving the culture and eating habits of a country and its diverse population groups.

    To determine tobacco point of sale advertising prevalence in Guatemala City, Guatemala and Buenos Aires, Argentina. Convenience stores (120 per city) were chosen from randomly selected blocks in low, middle and high socioeconomic neighbourhoods. To assess tobacco point of sale advertising we used a checklist developed in Canada that was translated into Spanish and validated in both countries studied. Analysis was conducted by neighbourhood and store type. All stores sold cigarettes and most had tobacco products in close proximity to confectionery. In Guatemala, 60% of stores had cigarette ads. High and middle socioeconomic status neighbourhood stores had more indoor cigarette ads, but these differences were determined by store type: gas stations and supermarkets were more prevalent in high socioeconomic status neighbourhoods and had more indoor cigarette ads. In poorer areas, however, more ads could be seen from outside the stores, more stores were located within 100 metres of schools and fewer stores had 'No smoking' or 'No sales to minors' signs. In Argentina, 80% of stores had cigarette ads and few differences were observed by neighbourhood socioeconomic status. Compared to Guatemala, 'No sales to minors' signs were more prevalent in Argentina. Tobacco point of sale advertising is highly prevalent in these two cities of Guatemala and Argentina. An advertising ban should also include this type of advertising.

    Buenos Aires, the capital city of Argentina, is surrounded by 24 neighboring districts forming the so-called Buenos Aires metropolitan area (AMBA) that holds a population of 14 million people. In this work, the atmospheric aerosol of this metropolitan area was characterized through the determination of mass concentration, black carbon and elemental concentrations, on PM10 and PM2.5 samples taken using a 'Gent' sampler. The sampling site was located at an urban area characterized by fast and heavy traffic and samples were collected each third day, along 24 hours, between October 2005 and February 2006. A number of elements (As, Ba, Br, Ce, Co, Cr, Cs, Eu, Fe, Hf, La, Na, Rb, Sb, Sc, Se, Sm, Th, Yb and Zn) were determined by Neutron Activation Analysis and their results, as well as those of gravimetric mass concentrations, were compared with historical data. Enrichment factors were calculated for both fractions, using Sc as reference element and Mason's crustal concentration values, showing enrichment for As, Br, Sb, Se and Zn. Although the number of analyzed filters is still small, a preliminary factor analysis was run on both fraction results and different source profiles were found. The attribution of the sources to soil, high temperature processes including refuse incineration, fuel combustion and others, metal processes, traffic and other anthropogenic ones is discussed.

    2012-10-01

    The annual cycle, annual and seasonal frequency and geographical distribution of hail in Argentina during the 1960-2008 period are examined. Eight regions covering the whole territory were defined based on the correlation of the mean annual hail frequency between all weather stations. Regions lying between 30° and 40°S as well as those dominated by mountains present the highest hail frequencies in Argentina. The eastern and coastal areas of the country experience hail events mainly during springtime but they may start in late winter and continue through the beginning of summer. Events in western and central Argentina also predominate in spring but the maximum frequencies are observed during summer months. Trends in the annual number of hail events calculated for each region indicate that events in northwestern and northeastern Argentina have been increasing as well as in southern Patagonia. On the other hand, in central Argentina, southern Buenos Aires-La Pampa, northern Buenos Aires-Litoral and northern Patagonia trends are negative and statistically significant in the first two regions, basically by the decrease of events during spring and summer.

    Leptospirosis is an infectious disease of wide global distribution, which is endemic in Argentina. The objective of this study was to obtain the genetic profiles of Leptospira spp. strains isolated from clinical cases of dogs in the province of Buenos Aires by the multiple-locus variable-number tandem repeat analysis (MLVA). Eight isolated canine strains were genotyped by MLVA, obtaining the identical profile of Leptospira interrogans serovar Canicola Hond Utrecht IV in the strains named Dogy and Mayo. The strains named Bel, Sarmiento, La Plata 4581 and La Plata 5478 were identical to the profile of the genotype of L. interrogans serovar Portlandvere MY 1039.The strain named Avellaneda was identical to the genotype profile of L. interrogans serovar Icterohaemorrhagiae RGA and the strain named SB had the same profile as the L. interrogans serovar Pomona Baires genotype and was similar to the profile of serovar Pomona Pomona genotype. It would be useful to include a larger number of isolates from different dog populations in various provinces of Argentina and to characterize the genetic profiles of the strains circulating in the country. The information obtained will be useful for the control of leptospirosis in the dog population. Copyright © 2014 Asociación Argentina de Microbiología. Publicado por Elsevier España.

  9. Epidemiology of Epstein-Barr virus-associated pediatric lymphomas from Argentina.

    Science.gov (United States)

    Chabay, Paola; Preciado, María Victoria

    More than 90% of the population is infected by Epstein-Barr virus (EBV), which has sophisticatedly evolved to survive silently in B cells for the life of infected individuals. However, if the virus-host balance is disturbed, latent EBV infection could be associated with several lymphomas. The age at primary infection varies substantially worldwide, and exposure to EBV is likely to be due to socioeconomic factors. In Argentina, EBV infection is mostly subclinical and 90% of patients are seropositive by the age of 3 years; therefore, its epidemiological characteristics resemble those of an underdeveloped or developing population. EBV-positive Hodgkin lymphoma (HL) in young adults from developed populations has been attributed to delayed primary EBV infection as suggested by the association with recent mononucleosis development. EBV-associated Burkitt lymphoma and Hodgkin lymphoma in children from Argentina display frequencies similar to those observed in developed countries, whereas EBV presence in pediatric diffuse large B-cell lymphoma is slightly increased compared to those populations. However, EBV presence is statistically associated particularly with patients < 10 years of age in all three entities. Therefore, a relationship between low age of EBV seroconversion and B-cell lymphoma development risk could be suggested in children from Argentina.

METODOLOGÍA: Se procesaron y analizaron fuentes estadísticas secundarias: se utilizaron dos encuestas domiciliarias que contenían un módulo sobre la utilización de servicios de salud y gastos asociados diseñado por el Ministerio de Salud y aplicado al Área Metropolitana de Buenos Aires en 1989 y 1995. RESULTADOS: Se constató un aumento del carácter socialmente regresivo del gasto de bolsillo en medicamentos entre 1989 y 1995, en un mercado farmacéutico que ha duplicado sus precios medios en el nuevo contexto de liberación de precios y apertura de las importaciones. Esta regresión se manifestó en el crecimiento del gasto directo de la compra de medicamentos, el aumento de la parte correspondiente a los medicamentos en la estructura del gasto privado para la salud y el incremento desigual del peso relativo de dicho gasto en los ingresos familiares. CONCLUSIONES: El gasto de bolsillo en medicamentos resulta un indicador eficiente de equidad financiera para el estudio de la protección de la población urbana argentina frente al riesgo de enfermar, y puede contribuir a la adecuación del marco regulador del mercado farmacéutico, mediante la incorporación de criterios sociales de evaluación a la ecuación farmacológica de seguridad y eficacia terapéutica.OBJECTIVE: To assess the level of equity in drug consumption patterns in the Metropolitan Area of Buenos Aires, Argentina, given the transformation of the Argentine pharmaceutical market since the deregulation of the country's economy in 1991.

We surveyed 35 transects located along secondary roads. Bird pest abundance was significantly higher at those sites with presence of woodlots (p<0.0001. Species-specific analyses revealed that abundance of both monk parakeet and picazuro pigeon was sensitive to the frequency of woodlots of tall and perennial tree species (Eucalyptus spp.; p<0.001, whereas eared dove abundance increased significantly with the frequency of woodlots composed by short and perennial tree species (Pinus spp., Casuarina spp.; p=0.002. Most bird pest species in the study area are more sensitive to the presence of woodlots rather than to the presence of croplands in the rural landscape. These results have practical implications, suggesting that an effective control of bird pest species in Buenos Aires province could be attained by managing exotic perennial tree species woodlots.

    Argentina has embarked on an ambitious domestic nuclear research and energy program. The venture promises to provide the nation with the infrastructure to play an important role in the nuclear export market in the years ahead. Buenos Aires built its program on a foundation of international support and assistance that overlay an emerging sophisticated industrial and scientific establishment. The foreign contribution sensitized Argentina to opportunities in the global market. This paper reports that Argentina operates two heavy-water/natural uranium reactors, Atucha I and Embalse. Producing, respectively, 320 MW(e) and 600 MW(e), they supply roughly 10 percent of the country's electricity. With a capacity factor of 84 percent, Atucha I is among the best operated plants in the world. Plans call for a third, 745 MW(e) power plant, Atucha II, to go on line in the early 1990s. During this period, construction also may begin on three 300 MW(e) plants, although the country's foreign indebtedness plus cost overruns in earlier construction will place a heavy burden on these plans

    Over the past 20 years the Fundacion Salud de Ayurved Prema Argentina has spread the knowledge of Ayurveda throughout Latin America. The Fundacion is based in Buenos Aires in the Argentine Republic, where it now runs courses in two of the country’s major medical schools - at the School of Medicine of the University of Buenos Aires, and the National University of Cordoba’s School of Medicine. Based on an MoU with Gujarat Ayurveda University, at Jamnagar, Gujarat, the Fundacion has been accredited as a Collaborating Center for teaching, assistance and research in the field of Ayurvedic Medicine in Argentina. This has led to successful missions to other countries in the region where the Fundacion and its associates have been able to start dialogues with governments, and in places hold sizeable courses. The knowledge of Ayurveda is now spreading throughout South and Central America and hardly a country remains untouched by it. PMID:21547054

    The coast of the Province of Buenos Aires, Argentina, has been studied to determine the wave-power potential. Using wave data (4 yr) from accelerometers, pressure sensors (1 yr) and a visual observation program (10 yr), the wave-power density was calculated at five locations. The annual average increases southwards, ranging between 2.3 kW/m at Mar de Ajo and 7.5 kW/m at Puerto Quequen. Annual averages of maximum wave power give 69 and 61.3 kW/m for Punta Medanos and Puerto Quequen, respectively. (Author).

    Full Text Available Objective: To show the toxicological and phylogenetic characterization of a native Microcystis aeruginosa (M. aeruginosa strain (named CAAT 2005-3 isolated from a water body of Buenos Aires province, Argentine. Methods: A M. aeruginosa strain was isolated from the drainage canal of the sewage treatment in the town of Pila, Buenos Aires province, Argentina and acclimated to laboratory conditions. The amplification of cpcBA-IGS Phcocyanin (PC, intergenic spacer and flanking regions was carried out in order to build a phylogenetic tree. An exactive/orbitrap mass spectrometer equipped with an electrospray ionization source (Thermo Fisher Scientific, Bremen, Germany was used for the LC/ESI-HRMS microcystins analysis. The number of cell/mL and [D-Leu1] Mcyst-LR production obtained as a function of time was modelled using the Gompertz equation. Results: The phylogenetic analysis showed that the sequence clustered with others M. aeruginosa sequences obtained from NCBI. The first Argentinian strain of M. aeruginosa (CAAT 2005-3 growing under culture conditions maintains the typical colonial architecture of M. aeruginosa with profuse mucilage. M. aeruginosa CAAT 2005-3 expresses a toxin variant, that was identified by LC-HRMS/Orbitrapas as [D-Leu1] microcystin-LR ([M+H]+=1 037.8 m/z. Conclusions: [D-Leu1] microcystin-LR has been also detected in M. aeruginosa samples from Canada, Brazil and Argentina. This work provides the basis for technological development and production of analytical standards of toxins present in our region.

    Four million people in Argentina are exposed to arsenic contamination from drinking waters of several center-northern provinces. A systematic review to examine the geographical distribution of arsenic-related diseases in Argentina was conducted, searching electronic databases and gray literature up to November 2013. Key informants were also contacted. Of the 430 references identified, 47 (mostly cross-sectional and ecological designs) referred to arsenic concentration in water and its relationship with the incidence and mortality of cancer, dermatological diseases and genetic disorders. A high percentage of the water samples had arsenic concentrations above the WHO threshold value of 10 μg/L, especially in the province of Buenos Aires. The median prevalence of arsenicosis was 2.6% in exposed areas. The proportion of skin cancer in patients with arsenicosis reached 88% in case-series from the Buenos Aires province. We found higher incidence rate ratios per 100 μg/L increment in inorganic arsenic concentration for colorectal, lung, breast, prostate and skin cancer, for both genders. Liver and skin cancer mortality risk ratios were higher in regions with medium/high concentrations than in those with low concentrations. The relative risk of mortality by skin cancer associated to arsenic exposure in the province of Buenos Aires ranged from 2.5 to 5.2. In the north of this province, high levels of arsenic in drinking water were reported; however, removal interventions were scarcely documented. Arsenic contamination in Argentina is associated with an increased risk of serious chronic diseases, including cancer, showing the need for adequate and timely actions. - Highlights: • Arsenic content in Argentina was associated with increased risk of chronic diseases. • The median arsenicosis prevalence was 2.6% in exposed areas. • The relative risk of mortality by skin cancer was 2.5 to 5.2 in affected areas. • The median percentage of water samples above the cut

    During the last decades, a significant deterioration of ambient air quality has been observed in Argentina. However, the availability of air pollution monitoring stations is still limited to only few cities. In this study, we investigated the genotoxicity of ambient levels of air pollution in Córdoba using the Tradescantia micronucleus assay. The experiment was performed from October, 2004 to April 2005. Pots with Tradescantia pallida were placed in three sites: Córdoba city center, characterized by important avenues with high traffic activity (cars, taxis, and public transport vehicles); the university campus, along a side road with heavy traffic of gasoline and diesel powered vehicles, buses and trucks; and a residential area, with no significant local sources of air pollution. Twenty young T. pallida inflorescences were collected from each sampling site in November, February and April. Micronuclei frequencies were determined in early tetrads of pollen mother cells and expressed as MCN/100 tetrads. Simultaneously, the environmental levels of total suspended particles (24 h mean) were determined for each site. A significant difference in micronuclei frequency was observed among sites ( p=0.036). Post-hoc analysis revealed that the residential area exhibited a lower micronuclei frequency than the university and city center areas. In conclusion, we found that the gradients of ambient air pollution of Córdoba are associated with changes in the spontaneous micronuclei frequency of Tradescantia pollen mother cells. These results indicate that in situ biomonitoring with higher plants may be useful for characterizing air pollution in areas without instrumental monitoring techniques, or for exploring the distribution of air contaminants at a microscale.

The content of Fe, Mg, Al, Mn, Zn, Pb, Ba, Cr, Hg, Cu, Ni, Cd and Sb was determined by inductively coupled plasma atomic emission spectrometry (ICP-OES in Morus alba tree bark collected in the cities of Buenos Aires and Mendoza. The main air pollutants detected in the Buenos Aires urban area were Ba, Cr, Cu and Ni and indicate significative difference from the Mendoza urban and periurban areas. Significantly, higher concentrations of Zn, Ba, Cr and Cu were recorded in the periurban area of the city of Buenos Aires than in Mendoza. Bark samples were strongly influenced by dust and show Al, Fe, Mg and other element accumulations that indicate that soil particles were carried out by wind. Elements like Ba and Zn, commonly linked to traffic emissions, showed the highest concentrations in the Buenos Aires metropolitan area, possibly due to more intensive vehicular traffic. Our results indicated that intensity of vehicular traffic and not city structure is responsible for air pollution.Um estudo comparativo dos elementos depositados nas cascas das árvores foi realizado nas áreas urbanas e na periferia de duas cidades das mais importantes da Argentina.

    Full Text Available The aim of this paper is to quantify one of the characteristics of the production function of the tourism sector in the province of Buenos Aires: the dominant factor content of their touristic resources, one simplified concept which shows the factors of production incorporated in goods. For its estimation and the touristic characterization of the different municipalities of the province, the following elements are used: the inventory of touristic resources of 134 municipalities of the province; their classification into the five categories listed by OEA; and the factor intensity of each category. One interesting result is that most municipalities with high touristic GDP show a dominant factor content of capital, the implication being that comparative advantage in the Province of Buenos Aires in Argentina is based on contemporary technical, scientific and artistic work. It may be concluded that there is place to exploit tourism in Argentina, what points to the need to accompany them with a correct design of public policies.

São mostradas experiências em áreas com cobertura de trigo, localizadas na área agrícola serrana da Província o Buenos Aires, Argentina. Os valores de RMS encontrados (29 mm Use of SAR images for soil surface moisture estimation requires taking into account the other factors that influence the radar backscattering signal, among which the surface cover roughness at centimeter scale is very important. There are several methods to determine the roughness, but many are expensive or complex field operation. A versatile and economic method that uses a photographic camera and a girded screen is presented. Each picture is numerically processed obtaining the RMS height, as parameter of the crop-soil complex roughness. By means of krigging geostatistics techniques the spatial distribution of roughness is estimated. Experiences in parcels with wheat cover, located in the hill agricultural area of Buenos Aires Province, Argentina are shown. The found RMS values (29 mm < RMS < 48 mm are analyzed with four roughness approaches. Their utility in order to estimate soil surface moisture status in agricultural parcels by means of their application like input into the SAR images backscattering models is stated.

Stands of Eucalyptus viminalis Labill. were identified, with ages between 4 and 14 years-old. Twenty-one individuals were felled with diameters ranging from 9,2 to 32,5 cm. Simple and multiple regression models were developed and volume, branch leaf and stem biomass were estimated. The best volume equations were based on lineal models and the most adequate behavior was obtained with d2. To estimate leaf, branch and stem, ln-ln models have been suggested, with diameter and h or only diameter. The leaf biomass presented the weakest adjustment. The distribution of trees biomass agrees with the bibliography. The proportion of crown biomass decreases with age; on the other hand, the proportion of stem biomass increases with age.

    During the period 2007-2008 several epizootics of Yellow fever with dead of monkeys occurred in southeastern Brasil, Paraguay, and northeastern Argentina. In 2008 after a Yellow fever outbreak an exhaustive prevention campaign took place in Argentina using 17D live attenuated Yellow fever vaccine. This vaccine is considered one of the safest live virus vaccines, although serious adverse reactions may occur after vaccination, and vaccine-associated neurotropic disease are reported rarely. The aim of this study was to confirm two serious adverse events associated to Yellow fever vaccine in Argentina, and to describe the analysis performed to assess the origin of specific IgM against Yellow fever virus (YFV) in cerebrospinal fluid (CSF). Both cases coincided with the Yellow fever vaccine-associated neurotropic disease case definition, being clinical diagnosis longitudinal myelitis (case 1) and meningoencephalitis (case 2). Specific YFV antibodies were detected in CSF and serum samples in both cases by IgM antibody-capture ELISA. No other cause of neurological disease was identified. In order to obtain a conclusive diagnosis of central nervous system (CNS) infection the IgM antibody index (AI(IgM) ) was calculated. High AI(IgM) values were found in both cases indicating intrathecal production of antibodies and, therefore, CNS post-vaccinal YFV infection could be definitively associated to YFV vaccination.

    Canine hepatozoonosis is an expanding tick-borne disease in Argentina. Hepatozoonosis was studied during 1 year in six dogs from the same household in Buenos Aires. Blood parasitemia with Hepatozoon gamonts was found in five dogs and all six were positive by PCR for Hepatozoon sp. Although the levels of parasitemia fluctuated during the year, no clinical signs of disease were detected during the follow up period. Amplification and sequencing of a 650 bases fragment of the 18S rRNA gene from all six dogs yielded fragments that were 99% identical to H. canis. The results of the partial 18S rRNA genotyping with the sub-clinical course of infection and lack of severe hematological abnormalities are compatible with clinical and molecular descriptions of Hepatozoon canis infection from other areas of the world. This is the first molecular characterization of Hepatozoon from Argentina.

    Full Text Available An approach is proposed on the study of financial consumption in the low-income sectors of Argentina. As mentioned in multiple research studies conducted in different Latin American countries, the study of this recent and widespread phenomenon demands to highlight some of the common places that have caused the characterization of the economic life of the popular sectors. We propose some theoretical guidelines to reconsider such consumption and analyze the results of our still ongoing investigation regarding consumption and indebtedness in the lower sectors of the metropolitan area of Buenos Aires.

    Mallo, Andrea C; Elíades, Lorena A; Nitiu, Daniela S; Saparrat, Mario C N

    Biological agents, such as fungal spores in the air in places where scientific collections are stored, can attack and deteriorate them. The aim of this study was to gather information on the indoor air quality of the Herbarium of Vascular Plants of the Museo de Ciencias Naturales de La Plata, Argentina, in relation to fungal propagules and inert particles. This study was made using a volumetric system and two complementary sampling methods: (1) a non-viable method for direct evaluation, and (2) a viable method by culture for viable fungal propagules. The non-viable method led to ten spore morphotypes being found from related fungal sources. A total of 4401.88spores/m 3 and 32135.18 inert suspended particles/m 3 were recorded. The viable method led to the finding of nine fungal taxa as viable spores that mostly belonged to anamorphic forms of Ascomycota, although the pigmented yeast Rhodotorula F.C. Harrison (Basidiomycota) was also found. A total count of 40,500fungal CFU/m 3 air was estimated for all the sites sampled. Both the non-viable and viable sampling methods were necessary to monitor the bio-aerosol load in the La Plata Herbarium. The indoor air of this institution seems to be reasonably adequate for the conservation of vascular plants due to the low indoor/outdoor index, low concentrations of air spores, and/or lack of indicators of moisture problems.

    2017-08-01

    The geomorphological evolution of a sand-dune barrier in Buenos Aires, Argentina, is analyzed as a factor regulating the fresh groundwater reserves available. The impact of geomorphological evolution and the consequences for the social and economic development of two coastal areas are assessed. This is one of the most important tourist destinations in the country; for study purposes, it was divided into a northern sector and a southern sector. In the southern sector, the exploitable groundwater is associated with the Holocene and upper Pleistocene geomorphological evolution, which generated three interrelated aquifer units, constituting a system whose useful thickness reaches at least 45 m. In contrast, the northern sector is restricted to two Holocene aquifer units, whose total thickness is on the order of 12 m. The morphological characteristics and the occurrence of the largest fresh groundwater reserves in the southern sector are indicators of better conditions for economic growth, which is mainly reflected on the expansion of real estate ventures. The relationships of transmissivity vs area of real estate ventures (Arev), and total water consumption vs Arev, are indicators for the sustainable management of the water resources. The approach chosen may be used by decision makers in other regions to assess the feasibility of future tourism projects on the basis of the availability of water resources associated with geomorphological features.

On behalf of the Argentine Radiation Protection Society (SAR), I would like to share with you the story of a dream that came true. Ten years ago, a few dedicated Argentine scientists started dreaming of having an IRPA International Congress in Argentina - the first time in Latin America. At the IRPA International Congress in Hiroshima, an informal presentation was made, which was only supported by SAR and encouraged by IRPA. There was already a bid for the IRPA International Congress in Madrid, strongly supported by the Argentine Government, through the Minister of Foreign Affairs, the Government of the City of Buenos Aires and national academic institutions. At that moment, many countries supported our proposal, sharing with us our dream. We worked very hard in these four years, but we were not alone. The strong support of authorities and staff of the Nuclear Regulatory Authority in Argentina was essential in the organization of IRPA12. Around the world, the cooperation of the International Atomic Energy Agency, the Pan-American Health Organization and the World Health Organization was also fundamental for fulfilment our dream. I would like to mention each of the national and international institutions and colleagues that are supporting IRPA12 with their work, with their funds or with their sponsorship, but there are so many! So, many thanks to all the national and international institutions that are supporting IRPA12; many, many thanks to all the Argentine colleagues and colleagues from all over the world of the different IRPA12 committees, and especially many thanks to all the authorities and colleagues who are here today, with us, sharing this IRPA12 and making real the motto of the Congress: Strengthening Radiation Protection Worldwide. Many thanks and welcome. (author)

    A partial report from a study dealing with Psychology's current status in Argentina is presented. Pursuant to this preliminary study 36,128 psychologists have taken their degree at both State and private universities in Argentina--between 1956, when the first Department of Psychology was created, and 1992. So, over a 32.5-million population (as per the 1991 census), there is a psychologist every 897 inhabitants, or 111 psychologists every 100,000 inhabitants. According to psychologists' geographical distribution, the highest density is to be found in the capital city of Buenos Aires (one psychologist every 246 inhabitants) while the lowest density is to be found in the Province of Chaco (one psychologist every 17,465 inhabitants). During year 1993, a total of 26,726 students have been studying Psychology at the different Argentine universities: Of these, 6,858 have taken their Psychology degree during this academic year. A great majority of psychologists work in the clinical field, being Psychoanalysis their prominent theoretical orientation. Ladies psychologists supposedly account for 85% of the overall number of psychologists. Psychological Associations have 24,878 active psychologists recorded, of which a great majority work in the clinical field.

    Full Text Available ABSTRACT The mainland population of the ruddy-headed goose (Chloephaga rubidiceps breeds in southern Patagonia and winters in the south of Buenos Aires province (Argentina, with a recent estimated size at around 900 individuals. This population is considered "in danger of extinction", while the Malvinas (Falkland Islands population is in well conservation status, with an estimated size of 40,000 birds. The aim of this work is to contribute with updated information about the ruddy-headed goose's population wintering in southern Buenos Aires province. The specific objectives were to better delimit its wintering area, to look for sites with large numbers, to study its habitat used, and to identify main threats to the species. Two intensive surveys were conducted during the austral winter of 1999. The results: (1 confirm the low abundance of the ruddy-headed goose supporting its critical conservation status, (2 corroborate its very restricted distribution, with more than 80 % of sightings concentrated in an area of 13,000 ha in southern Buenos Aires province, and (3 suggest that changes in the species' habitat use during the wintering season appear to be a response to changes in habitat availability, resulting from the growth of crops and pastures. The overlap between the species wintering distribution and the main wheat cropping areas of Argentina results in serious threats to this goose. Management actions are discussed to contribute to the conservation of this endangered species.La población continental del Cauquén colorado (Chloephaga rubidiceps cría en el sur de la Patagonia e inverna en el sur de la provincia de Buenos Aires (Argentina, con un tamaño poblacional estimado recientemente en alrededor de 900 individuos.

    Buyers are lining up for Argentina's two big state-controlled petrochemical groups, Buenos Aires-based Petroquimica General Mosconi (PGM) and Petroquimica Bahia Blance (PBB). However, feedstock supply contracts with government-owned oil group Yacientos Petroliferos Fiscales (YPG) and gas group Gas del Estado hold the key to both sales. Shell Compania Argentina Petroleo SA (CAPSA), Perez Companc, and Global Petroleum have already bought PGM tender documentation. Shell says it will bid for PGM if the feedstock contract with YPF is acceptable. In addition to price and volume, Shell says the length is critical; it wants a 15-year deal, but would settle for 11. YPF initially sought a five-year contract. PGM, which produces 300,000 m.t./year of aromatics, plus oxo alcohols, methanol, and methyl tert-butyl ether, has sales of $150 million/year

    Full Text Available This paper analyses popular wisdom and memory transmission regarding State terrorism and forced disappearance, which are circulating among youth living around Hospital Posadas, located in Haedo, a province to Buenos Aires, Argentina. At this hospital, there was, under the military dictatorship (1976-1983, a Clandestine Imprisonment Center, where people were kept prisoner as disappeared. Therefore, at this facility both practices of health restoration and torture and murder perpetration coexisted. Through thirty indepth interviews carried out among neighbor young people, the existence of manifold knowledge fractures and memory transmission about State violence is verified, being a result from the social relations breakthrough that used to articulate the neighborhood and the hospital, and from the material life conditions promoting undifferentiated historical and political time awareness.

    Full Text Available We analyzed 391 samples from 12 Argentinian populations from the Center-West, East and North-West regions with the Illumina Human Exome Beadchip v1.0 (HumanExome-12v1-A. We did Principal Components analysis to infer patterns of populational divergence and migrations. We identified proportions and patterns of European, African and Native American ancestry and found a correlation between distance to Buenos Aires and proportion of Native American ancestry, where the highest proportion corresponds to the Northernmost populations, which is also the furthest from the Argentinian capital. Most of the European sources are from a South European origin, matching historical records, and we see two different Native American components, one that spreads all over Argentina and another specifically Andean. The highest percentages of African ancestry were in the Center West of Argentina, where the old trade routes took the slaves from Buenos Aires to Chile and Peru. Subcontinentaly, sources of this African component are represented by both West Africa and groups influenced by the Bantu expansion, the second slightly higher than the first, unlike North America and the Caribbean, where the main source is West Africa. This is reasonable, considering that a large proportion of the ships arriving at the Southern Hemisphere came from Mozambique, Loango and Angola.

    This stakeholder assessment of HIV/AIDS service providing institutions in Argentina offers insights into the HIV/AIDS crisis in Spanish-speaking Latin America from an institutional level and makes recommendations for strengthening the work and functioning of these institutions. This stakeholder assessment was conducted to determine how HIV/AIDS prevention and management in Argentina affects and is affected by relevant HIV/AIDS institutions. Semi-structured qualitative interviews were conducted with 13 key leaders of organizations working in HIV/AIDS prevention in Buenos Aires including non-governmental, governmental, and academic institutions. Analyses of interviewee comments are presented according to four major themes: network connections, program resources, perceptions of success, and challenges. Key findings include the need for strengthening formal networks, increasing the involvement of other non-AIDS related social institutions in promoting HIV prevention, finding more sustainable funding options, working more effectively with the public sector to create policies and regulations favorable to the HIV/AIDS field, and addressing the lack of perceived susceptibility to HIV/AIDS in Argentine culture. From leaders' comments, recommendations are made for strengthening the HIV/AIDS network among key institutions including adapting the UNAIDS "Three Ones" principal to create one crosssector office responsible for coordinating HIV/AIDS work, formalizing agreements with institutions outside of Buenos Aires, increasing the role of schools in HIV/AIDS awareness, and designing programs that address lack of perceived susceptibility to HIV/AIDS among Argentines.

Este indicador es obtenido en función de observaciones meteorológicas estándar a partir de un modelo que incluye la alteración del perfil vertical del viento ocasionada por la presencia de partículas de suelo en el aire y es expresado en términos de la probabilidad de que la potencia del viento supere las condiciones umbrales para el comienzo del proceso. Si bien el índice fue obtenido para suelo seco y desnudo, la metodología permite avanzar hacia un modelo de evaluación de riesgo más general, si se determinan previamente los valores de velocidad de fricción umbral que corresponden a distintas condiciones que afectan la resistencia del suelo tales como la humedad del suelo, el contenido de materia orgánica, cobertura y uso de la tierra. Este modelo ha sido utilizado para evaluar la distribución espacial del riesgo de erosión eólica en la Provincia de Buenos Aires, Argentina.This paper proposes a climatic index to estimate the wind erosion risk based upon physical laws that quantify the effect of environment's aggression (atmospheric turbulence on system resistance (soil texture. This index is obtained as a function of standard meteorological observations including the alteration of the wind profile produced by the presence of soil particles in the air and it is expressed in terms of the probability for the wind power to exceed the threshold conditions. Although this index was obtained for dry and bare soil, it may mean an advance towards a more general model for risk evaluation if other factors intervening in soil resistance, such as soil humidity, organic material content, land cover and use are included.

Material y métodos: Se utilizó un modelo ecológico, que evaluó las tasas estandarizadas de muerte prematura (≤ 74 añosdurante el período 2000-2010. Asimismo, se examinó la relación entre la condición socioeconómica medida en deciles denecesidades básicas insatisfechas por departamento geográfico y la muerte prematura. La unidad de análisis fueron los 512departamentos de la Argentina y las 15 comunas de la ciudad de Buenos Aires. Resultados: La condición socioeconómica estuvo significativamente asociada con la muerte prematura en la Argentina durante el período analizado. En todas las provincias y regiones se observó un gradiente lineal entre la muerte precoz y la condición socioeconómica. Sin embargo, la pendiente de desigualdad entre los componentes de la condición socioeconómica varió significativamente entre los distintos departamentos. Mientras que en toda la Argentina la diferencia absoluta en la tasa estandarizada de muerte prematura entre los componentes extremos de condición socioeconómica fue de 10 muertes (rango:7,81-12,36 por cada 10.000 personas por año, en la ciudad de Buenos Aires esa diferencia fue de 61 muertes (rango: 53-69.Las comunas del sur de la ciudad de Buenos Aires fueron las zonas con mayor desigualdad social y sanitaria de la Argentina. Conclusiones: Aunque la inequidad social tuvo un impacto significativo en la muerte prematura en todo el período en toda la Argentina, la ciudad de Buenos Aires se mostró como la región más desigual.

    Full Text Available The population of Argentina is the result of the intermixing between several groups, including Indigenous American, European and African populations. Despite the commonly held idea that the population of Argentina is of mostly European origin, multiple studies have shown that this process of admixture had an impact in the entire Argentine population. In the present study we characterized the distribution of Indigenous American, European and African ancestry among individuals from different regions of Argentina and evaluated the level of discrepancy between self-reported grandparental origin and genetic ancestry estimates. A set of 99 autosomal ancestry informative markers (AIMs was genotyped in a sample of 441 Argentine individuals to estimate genetic ancestry. We used non-parametric tests to evaluate statistical significance. The average ancestry for the Argentine sample overall was 65% European (95%CI: 63-68%, 31% Indigenous American (28-33% and 4% African (3-4%.

    Diana María Hohl

    Full Text Available Abstract The aim of this work was to describe the phenotypic and genotypic variability related to iris color for the population of Buenos Aires province (Argentina, and to assess the usefulness of current methods of analysis for this country. We studied five Single Nucleotide Polymorphisms (SNPs included in the IrisPlex kit, in 118 individuals, and we quantified eye color with Digital Iris Analysis Tool. The markers fit Hardy-Weinberg equilibrium for the whole sample, but not for rs12913832 within the group of brown eyes (LR=8.429; p=0.004. We found a remarkable association of HERC2 rs12913832 GG with blue color (p < 0.01 but the other markers did not show any association with iris color. The results for the Buenos Aires population differ from those of other populations of the world for these polymorphisms (p < 0,01. The differences we found might respond to the admixed ethnic composition of Argentina; therefore, methods of analysis used in European populations should be carefully applied when studying the population of Argentina. These findings reaffirm the importance of this investigation in the Argentinian population for people identification based on iris color.

Los hallazgos han corroborado resultados previos y han aportado nuevos conocimientos. Se confirmó la ambivalencia de los discursos sobre el aborto, ya que primaron una opinión favorable a su despenalización, y una representación social fundada en un eje moral opuesto al aborto. De los resultados se desprende la necesidad de investigar los puntos de vista de los varones sobre los derechos de mujeres y varones, y de profundizar los sondeos de opinión a través de estudios cualitativos en los que se indaguen sus representaciones sociales en el campo de los derechos sexuales y reproductivos.

    Using the approaches of history of the present, this article recovers the discussions surrounding the 12th International Conference on Cancer carried out in Buenos Aires in 1978, in reaction to which Georges Périès organized a "counter-conference" in Paris. In order to understand this discussion, the political situation of the time is described, as is the state of human rights at the time in Argentina, the role of the media - in particular the newspapers La Nación and Clarín and the magazine Gente - and the institutional position adopted by the National Academy of Medicine, as expressed in a letter sent to the presidents of the primary scientific societies of the world. The letter is reprinted in this text as a documentary source, taken from Memoria: Año 1978 (Presidencia de Dr. José E. Rivarola) [Acta: Year 1978 (Presidency of Dr. José E. Rivarola)]. The framework of the discussion makes reference to science's social policy versus science's supposed neutrality and the role of scientific societies.

    The Infectious Diseases Hospital Francisco Javier Muñiz, Buenos Aires, Argentina, is the oldest in Latin America. It is over 100 years old and has a history worthy of pride. It became known as "Hospital of the pests" and was preceded by the old House of Insulation, which served as a quarantine station during epidemics of cholera, yellow fever and smallpox. The new House of Insulation, built in the neighborhood of Parque Patricios ("Barracks Hospital"), was renamed in 1904 in memory of Francisco Javier Muñiz, a former military doctor, naturalist and paleontologist. Its technical name is "Porteño Care Centre and National Reference Regional Infectious-Contagious Disease". It receives numerous national and foreign undergraduate and postgraduate students in its Departments of Infectious Diseases and Respiratory Diseases.

  2. Comments on Environmental and Sanitary Aspects of the Scorpionism by Tityus trivittatus in Buenos Aires City, Argentina

    Full Text Available Deaths by venomous animals are medical emergencies that can lead to death and thus constitute sanitary problems in some regions of the world. In the South of America, the accidents by these animals are a common sanitary problem especially in warm, tropical or subtropical regions, related with rural work in several countries. Argentina is located in the extreme South of South America and a minor part of the continental surface is in tropical or subtropical regions, where most of the accidents by venomous animals happen. However, in the big cities in the center and South of the country, with no relation to rural work, scorpionism, mostly due to the synanthropic and facultative parthenogenetic scorpion Tityus trivittatus, has become a sanitary problem in the last few decades. This scorpion is present in the biggest cities of Argentina and in the last decades has killed over 20 children in provinces of the center and north of the country, mostly in big cities. In addition, it seems that this species is growing and spreading in new regions of the cities. In this revision, some characteristics of this scorpion regarding its habitat, spreading in Buenos Aires city, combat measures and available treatments are discussed.

    Goats, called “the cow of the poor”, are the livestock species with the most significant population growth worldwide in recent years. Gastrointestinal parasitism constitutes one of the main constraints to its outdoor and extensive breeding in temperate and tropical countries. Despite a Creole goat population of nearly 4 million heads, local reports on parasitological prevalence are scarce, and while Fasciola hepatica infection is spread all over Argentina, the goat is usually neglected as a reservoir and economic losses are not considered. To evaluate gastrointestinal parasitism prevalence and associations between parasite genera and species, with emphasis on fascioliasis, Creole goats from the plateau and Andean regions from western Argentina were investigated by coprological techniques, and associations were statistically assessed. Eighty-five percent (85%) of the animals harbored one or more parasite types, while 46% showed mixed infections. Significant positive associations between F. hepatica + Strongyle eggs, Eimeria sp. + Nematodirus sp. and Nematodirus sp. + Trichuris ovis were detected. Further studies are required to define the causality of these associations and their relevance in epidemiology. F. hepatica is rarely considered as goat parasite in the country, but a 33% prevalence poses an interrogation on the role goats play on the transmission and dissemination of this zoonotic trematode.

    1986-06-01

    This discussion of Argentina covers geography, the people, history and political conditions, government, economy, foreign relations, and relations between the US and Argentina. In 1985, the population of Argentina was estimated to be 30.6 million with an estimated annual growth rate of 1.5%. The infant mortality rate is 34.1/1000, and life expectancy is 70.2 years. Argentina, which shares land borders with Bolivia, Brazil, Chile, Paraguay, and Uruguay, is bounded by the Atlantic and the Antarctic Oceans. Descendants of Italian and Spanish immigrants predominate in Argentina, but many trace their origins to British and West and East European ancestors. In recent years, there has been a substantial influx of immigrants from neighboring Latin American countries. The native Indian population, estimated to be 50,000, is concentrated in the peripheral provinces of the north, northwest, and south. What is now Argentina was discovered in 1516 by the Spanish navigator Juan de Solia. The formal declaration of independence from Spain was made on July 9, 1816. In the late 19th century, 2 forces worked to create the modern Argentine nation: the introduction of modern agricultural techniques and the integration of Argentina into the world economy. Argentina has impressive human and natural resources, but political conflict and uneven economic performance since World War II have impeded full realization of its considerable potential. Yet, it is one of the wealthiest countries in Latin America. Among the reasons for the military coup of March 1976 was the deteriorating economy, caused by declining production and rampant inflation. Under the leadership of the Minister of the Economy, the military government focused attention on those immediate problems, and, in 1978, embarked on a new development strategy focusing on the establishment of a free market economy. There was little improvement in the economy, and a new economic plan was introduced in 1985 which has capped inflation by

    Full Text Available Cemeteries with many water-filled containers, flowers, sources of human blood, and shade are favorable urban habitats for the proliferation of Aedes aegypti, a vector of yellow fever and dengue. A total of 22,956 containers was examined in the five cemeteries of the city of Buenos Aires, Argentina. The vector was found in four cemeteries that showed an average infestation level of 5.5% (617 positive out of 11,196 water-filled containers. The four cemeteries positive for Ae. aegypti showed significantly different (p<0.01 infestation levels. Vegetation cover and percentage of infestation were significantly correlated (p<0.01, but neither cemetery area nor number of available containers were significantly related to the proportion of positive vases. Our results suggest that the cemeteries of Buenos Aires represent a gradient of habitat favorableness for this vector species, some of which may act as foci for its proliferation and dispersal.

    ía relativamente más a la calidad del aire que a la del suelo. La magnitud de este proceso estaría regida, principalmente, por el área disponible para la erosión. En suelos sometidos a manejos agrícolas, frecuentemente desnudos y de bajo grado de evolución como los Ustipsammentes y Haplustoles, la erosión eólica tendría efectos intermedios, afectando tanto a la calidad del suelo como a la del aire. Finalmente, en suelos relativamente más evolucionados y sometidos a manejos agrícolas como los Hapludoles, la erosión afectaría en mayor medida a la calidad del suelo, siendo la emisión de partículas finas de relativa menor importancia.Wind erosion can impact soil and air quality. The magnitude of these effects depends on the soil type and management conditions, and is associated with the transport conditions of soil particles: saltation and rolling affect soil quality to a greater extent while suspension tends to increase the emission of fine particles to the atmosphere. The objective of this research was to determine the magnitude of both type of movements in soils of Argentina, in order to predict potential effects on soil or air quality. This study was carried out in four provinces of Argentina: Chaco (CHA, San Luis (SLU, La Pampa (LPA and Río Negro (PAT. In each case, wind erosion was measured in the 1 ha-square fields by means of BSNE samplers. Results indicated that the total amount of transported material, the so-called mass flux (FM as well as the absolute amount of eroded soil (Q were higher in sites with less developed soils of SLU (Ustipsamment and LPA (Haplustoll and lower in sites with a better developed soil of CHA (Hapludoll or with less developed soil but with permanent soil cover with natural grasses of PAT (Haplargid. Saltation and rolling were the main transport forms in SLU, LPA and CHA and suspension in PAT. Though low (10%, the plant coverage existing in this last site was enough to increase the height of the wind profile and to favor the transport

    2011-11-01

    One of the most important and active pioneers of the space activities in Argentina was Miguel Sánchez Peña, an aeronautical engineer and an officer of the Argentine Air Force. Sánchez Peña was the organizer of Argentina's governmental space program in the 1970s and part of the 80s, and contributed immeasurably to the Nation's sounding rocket program. Born in Mendoza, Argentina in 1925, Sánchez Peña attended the Military Aviation School (Escuela de Aviación Militar) in Córdoba, and later the Air Force Engineering School. Graduated as an engineer in 1959 he was sent to the University of Michigan in the United States to complete his graduate studies earning a Masters of Science degree in Aerospace Engineering. There he had the opportunity to study with several future NASA astronauts such as Theodore Freeman, Edward White and James McDivitt. After his return to Argentina in 1961 he was put in charge of the Space Development Group (Grupo de Desarrollos Espaciales) of the Air Force in Córdoba. While with the Air Force he managed the development of a family of various sounding rockets for high altitude research. Sánchez Peña was also in charge of the first Argentine rockets launched from Antarctica in 1965, as well as the first tests on an Argentine-fabricated rocket (Orión) from Wallops Island in the United States, in 1966. The Orion was the first operational sounding rocket constructed in South America. In the middle of the 1970s Miguel Sánchez Peña was named president of the CNIE (National Space Research Commission). Starting with just a modest one-desk office at the Argentine Air Force headquarters, in only a few years he turned CNIE into a multi-center organization with several hundred employees, three operational launch centers across the country and a family of research rockets open to the international scientific community. He was also actively representing Argentina in many IAF congresses, and was a member of the International Academy of

    Full Text Available This article discusses the changes in injecting drug use from 1998 to 2003 in Buenos Aires, Argentina. The Rapid Situation Assessment and Response methodology was used to obtain the information. Quantitative and qualitative techniques were triangulated: 140 current IDUs and 35 sex partners of injection drug users (IDUs were surveyed; 17 in-depth interviews with the surveyed IDUs and 2 focus groups were held, as well as ethnographic observations. The way in which risk and care practices among injecting drug users changed and the influence of the HIV/ AIDS epidemic on this process are described. In recent years, the frequency of injection practices and sharing of injecting equipment has decreased, while injecting drug use is a more hidden practice in a context of increasing impact of the disease in the injecting drug use social networks and changes in the price and quality of drugs. Knowledge about these changes helps build harm reduction activities oriented to IDUs in their particular social context.Este artículo refleja los cambios en el uso inyectable de drogas producidos entre 1998 y 2003 en Buenos Aires, Argentina.

    One of the most important developers of liquid propellant rocket engines in Argentina was Polish-born Ricardo Dyrgalla. Dyrgalla immigrated to Argentina from the United Kingdom in 1946, where he had been studying German weapons development at the end of the Second World War. A trained pilot and aeronautical engineer, he understood the intricacies of rocket propulsion and was eager to find practical applications to his recently gained knowledge. Dyrgalla arrived in Argentina during Juan Perón's first presidency, a time when technicians from all over Europe were being recruited to work in various projects for the recently created Argentine Air Force. Shortly after immigrating, Dyrgalla proposed to develop an advanced air-launched weapon, the Tábano, based on a rocket engine of his design, the AN-1. After a successful development program, the Tábano was tested between 1949 and 1951; however, the project was canceled by the government shortly after. Today, the AN-1 rocket engine is recognized as the first liquid propellant rocket to be developed in South America. Besides the AN-1, Dyrgalla also developed several other rockets systems in Argentina, including the PROSON, a solid-propellant rocket launcher developed by the Argentine Institute of Science and Technology for the Armed Forces (CITEFA). In the late 1960s, Dyrgalla and his family relocated to Brazil due mostly to the lack of continuation of rocket development in Argentina. There, he worked for the Institute of Aerospace Technology (ITA) until his untimely death in 1970. Ricardo Dyrgalla deserves to be recognized among the world's rocket pioneers and his contribution to the science and engineering of rocketry deserves a special place in the history of South America's rocketry and space flight advocacy programs.

    This study examined the lifetime prevalence and correlates of attempted suicide among transgender persons in Argentina. Data were derived from a nation-wide, cross-sectional survey conducted in 2013. We assessed individual, social, and structural correlates of reporting a history of attempting suicide using logistic regression. Among 482 participants, the median age was 30, 91% identified as transwomen, and 32% resided in the Buenos Aires metropolitan area. A lifetime suicide attempt was reported by 159 (33%), among whom the median age at first attempt was 17. In a multivariate model, internalized stigma was positively associated with a history of suicidal behavior, while participants with stable housing had reduced odds of prior suicide attempt(s). These findings suggest that reducing stigma and mitigating structural vulnerabilities (through, for example, the enactment and enforcement of laws that prohibit discrimination based on gender identity to ensure equitable access to housing) could be effective targets for intervention to reduce suicide attempts among transgender individuals in Argentina.

The methodology was applied to the emissions the particulate material with a size smaller than 10 μm (PM10 generated from the operation of open pit quarries, near General Roca town (Argentina; and then evaluates their dispersion and possible impact on human health and / or the environment. The seasonal variations of the dispersion were analyzed and the Gaussian dispersion model used is AERMOD. The results showed that PM10 dispersion in different atmospheric conditions and emissions in 2010, don´t influence urban areas near quarries and don´t that exceed the legal limit. From the analysis of the seasonal variations of the dispersion changes were observed in the extension of the plume and in the maximum hourly concentration, especially in the autumn and winter seasons. The results of the modeling (maximum hourly concentration values were compared with aerosol concentration data, obtained by remote sensors; Resulting in a determination coefficient (R2 ~ 0.7. The proposed work methodology can be incorporated as a control tool in government agencies for the evaluation and management of air quality so as to prevent unsatisfactory scenarios.

    Full Text Available OBJETIVO: Medir la equidad manifestada por los patrones de consumo de medicamentos en el Área Metropolitana de Buenos Aires, Argentina, a la luz de las transformaciones operadas en el mercado farmacéutico argentino después de la desregulación de la economía en 1991. METODOLOGÍA: Se procesaron y analizaron fuentes estadísticas secundarias: se utilizaron dos encuestas domiciliarias que contenían un módulo sobre la utilización de servicios de salud y gastos asociados diseñado por el Ministerio de Salud y aplicado al Área Metropolitana de Buenos Aires en 1989 y 1995. RESULTADOS: Se constató un aumento del carácter socialmente regresivo del gasto de bolsillo en medicamentos entre 1989 y 1995, en un mercado farmacéutico que ha duplicado sus precios medios en el nuevo contexto de liberación de precios y apertura de las importaciones. Esta regresión se manifestó en el crecimiento del gasto directo de la compra de medicamentos, el aumento de la parte correspondiente a los medicamentos en la estructura del gasto privado para la salud y el incremento desigual del peso relativo de dicho gasto en los ingresos familiares. CONCLUSIONES: El gasto de bolsillo en medicamentos resulta un indicador eficiente de equidad financiera para el estudio de la protección de la población urbana argentina frente al riesgo de enfermar, y puede contribuir a la adecuación del marco regulador del mercado farmacéutico, mediante la incorporación de criterios sociales de evaluación a la ecuación farmacológica de seguridad y eficacia terapéutica.

    Argentina is a large country situated at the southern end of the Americas. It is highly urbanized, and almost one-third of the population lives in the capital city and its surrounding area (Buenos Aires). The population is composed of heterogeneous groups, formed primarily by descendants of European immigration who constitute 85% of the inhabitants. In the last 30 years, Argentina has witnessed a growth in the elderly population from less than 7% to nearly 10% of the total population. Additionally, in Buenos Aires City, more than 17% are aged 65 or older. The healthcare systems for the elderly lack nationwide coverage. The Programa de Atención Médica Integral (PAMI) is the largest program for elderly care. It is a state-run program for disabled and senior citizens. PAMI serves 65% of the approximately 3.6 million older people in Argentina. The quality of PAMI healthcare delivery has decreased in the last 2 decades and has largely declined since the Argentinean economic crisis of late 2001. The rehabilitation and long-term care services are relatively underdeveloped, and fewer than 2% of senior citizens live in residential or nursing homes. Recently, the government has proposed a system of care built up from the primary care resources of the community.

    Full Text Available Las relaciones argentino-iraníes se encuentran, a nivel político, en el punto más bajo de su historia. Suele afirmarse que tal situación es la relación directa de los atentados terroristas ocurridos en Buenos Aires en 1992 y 1994 donde las autoridades judiciales argentinas han presentado indicios que relacionarían a funcionarios iraníes. En este trabajo se afirma que aunque tales hechos han tenido influencia las relaciones argentino iraníes constituyen una variable dependiente de los modelos de inserción internacional de Argentina. En tal sentido, la década del gobierno de Carlos Menem (1989-1999 es estudiada como modelo para analizar tales cambios en la política exterior argentina y su impacto en las relaciones argentino-iraníes.

    Bats are potential reservoirs of many vector-borne bacterial pathogens. The aim of the present study was to detect species of Anaplasma, Ehrlichia, Neorickettsia, Rickettsia, Borrelia and Bartonella in Brazilian free-tailed bats (Tadarida brasiliensis, Molossidae) from Buenos Aires city, Argentina. Between 2012 and 2013, 61 T. brasiliensis from urban areas of Buenos Aires city were studied. The samples were molecularly screened by PCR and sequencing. Five bats (8.2%) were positive to Neorickettsia risticii, one (1.6%) was positive to Rickettsia sp. and three bats (4.9%) to Bartonella sp. For molecular characterization, the positive samples were subjected to amplification and sequencing of a fragment of p51 gene for N. risticii, a fragment of citrate synthase gene (gltA) for Rickettsia genus and a fragment of gltA for Bartonella genus. Phylogenetic tree was constructed using the maximum-likelihood method. Phylogenetic analysis of N. risticii detect in our study revealed that it relates to findings in the USA West Coast; Rickettsia sp. detected is phylogenetically within R. bellii group, which also includes many other Rickettsia endosymbionts of insects; and Bartonella sp. found is related to various Bartonella spp. described in Vespertilionidae bats, which are phylogenetically related to Molossidae. Our results are in accordance to previous findings, which demonstrate that insectivorous bats could be infected with vector-borne bacteria representing a potential risk to public health. Future research is necessary to clarify the circulation of these pathogens in bats from Buenos Aires. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Nuclear activities in Argentina are restarted. After almost two decades of near stagnation, the governments political decision of August 2006 regarding electrical energy production, considered the nuclear option as a valid one to solve the problems of the growing demand of electrical energy. This decision triggered again the activities related to the finalization of the third nuclear power reactor (Atucha-II), now actively progressing, the construction of a prototype of the CAREM integral advanced reactor, the life extension of the Embalse CANDU nuclear power plant (NPP) and the studies for the emplacement of a fourth NPP in an appropriate site. In all those years of near stagnation, there were notable exceptions related to the design and construction of experimental and radioisotope production reactors, led by INVAP, a state-owned industry, which exported its production. The accompanying industries of nuclear fuel elements production also remained active, given the demand of the two active NPPs. Meanwhile, the National Atomic Energy Commission of Argentina continued the efforts on research and development that were at the base of the technological achievements of the nuclear activities in Argentina. Nuclear safety studies associated with Atucha II and Embalse NPPs and radiological safety were also a substantive part of the continued efforts by Nucleo-Electrica de Argentina SA and the Nuclear Regulatory Authority of Argentina

    A paleoenvironmental reconstruction of the southeast coast of Buenos Aires province, Argentina, is made mainly on the basis of paleontological and paleoichnological studies, supported by sedimentological analyses and radiocarbon dating. Continental late Pleistocene and continental, transitional, and marine Holocene stratigraphic units are identified. The former comprises fossil mammals and ichnites of 16000-12,000 BP. The continental early Holocene time, ca. 8100 BP, is represented by an interdune paleoenvironment in which shallow brackish ponds were colonized by diatoms, fish, rodents, and birds. A transitional paleoenvironment in the middle Holocene—6930-6570 BP—is recorded by deposits formed by estuarine crabs. During the late Holocene, between 5000 and 4800 BP, a marine transgression was recorded by a rich mollusc fauna.

    Results of the first stable isotopes analysis (δ""1"3C and δ"1"5N) of archaeological sites located in the southwest of the province of Buenos Aires (Argentina) are presented. Both the construction of an isotopic ecology and prehistoric human diets of the sector are explored. The isotopic ecology indicates diverse environments in which marine animals have enriched δ"1"3C col. values; while terrestrial species such as coypo, greater rhea and large-sized herbivores have the poorest values that are indistinguishable among the different taxa. Furthermore, ducks and a hairy armadillo showed intermediate values. Human isotopic values indicate a diet based on the consumption of meat. These proteins came predominantly from terrestrial animals complemented by marine resources. The local archaeological record is consistent with this information, as the main faunal resources are terrestrial species; nevertheless a scarce representation of marine fauna, mainly Otariids, is registered. In this paper we present the first isotopic values for the studied area and thus it is a preliminary contribution that must be further investigated with new samples

    Concentrations of 21 Pb and 137 Cs in sediment samples collected from two cores at a drainage channel to the La Plata river estuary in Buenos Aires, Argentina, were measured using ultralow-background detection systems. The 21 Pb data were used to determine the rate of sediment accumulation of the sites. These results were correlated with some heavy metal (chromium and lead) concentrations of the samples in an attempt to characterize the historical input of contaminants due to the industrial development, which has taken place in this area over the last century. The 137 Cs measurements demonstrate that cesium dating is not adequate in regions of the southern hemisphere

    Full Text Available In this work, we analyzed data from ethnobotanical surveys of functional and nutraceutical legumes (Leguminosae commercialized in the metropolitan area of Buenos Aires, Argentina. The surveys took place in outlets of the general commercial circuit and the restricted circuits belonging to Bolivian and Chinese immigrants. We recorded the species, its products, local therapeutic uses, and available published data on biological activity and effects. Nineteen species were found: Arachis hypogaea var. hypogaea, Cicer arietinum, Glycine max, Lablab purpureus, Lens culinaris, Lupinus albus, L. mutabilis, Medicago sativa, Phaseolus lunatus, P. vulgaris, Pisum sativum, Prosopis alba, Tamarindus indica, Trifolium repens, Trigonella foenum-graecum, Vicia faba, Vigna angularis, V. radiata and V. unguiculata var. unguiculata. Most of these species (15 were found in the general commercial circuit, whereas the rest (4 only in the restricted commercial circuits of immigrants, including L. mutabilis, which deserves a wider diffusion. In most cases, the local uses assigned to a surveyed species correspond to the information available in the literature on the species’ biological activity and effects. This paper provides new insights for ethnobotanical studies and highlights the therapeutic relevance of legumes in the study area.

    Full Text Available Las agallas son estructuras anormales que se desarrollan en las plantas como respuesta a la acción de un agente inductor. La fauna de insectos cecidógenos de la región Neotropical es poco conocida en comparación a otras regiones, y en la Argentina, los registros son particularmente incompletos. Con el objetivo de identificar y caracterizar los insectos cecidógenos presentes en la región Rioplatense, se realizaron relevamientos a campo y revisión bibliográfica. En La Plata, Punta Lara, Punta Indio, isla Paulino, Bernal, isla Martín García e isla Oyarvide se recorrieron transectas al azar de una hora por visita. Las agallas se recolectaron para obtención de adultos, que luego se identificaron empleando claves taxonómicas y material de referencia. Se listaron 33 morfoespecies de insectos cecidógenos sobre 26 especies vegetales, de las cuales 8 son interacciones registradas por primera vez de la Argentina y en 3 especies vegetales se registra por primera vez la presencia de agallas. La mayoría de los insectos inductores pertenecieron al Orden Hemiptera y entre ellos, el grupo más frecuente fue Psylloidea. Las familias vegetales Asteraceae y Anacardiaceae concentraron la mayor riqueza de especies cecidógenas. El 55% de las agallas fueron foliares, y el 33% fueron clasificadas morfológicamente como globoides. Se destaca la necesidad de continuar estos estudios en la Argentina.

    There was a significant increase in the number of women demanding gynecological care in public hospital of the Great Buenos Aires, Argentina, between 1997 and 1998. It was necessary to update the prevalence of associated microorganisms in order to review the laboratory support and adjust prevention and control guidelines. Samples from vaginal and endocervical discharge, from total cases: 84 adolescents (15 to 19 years) and 784 adults (20-60 years) attended in 1997-1998, were studied. Neisseria gonorrhoeae, Streptococcus agalactiae, Trichomonas vaginalis, Candida spp, and bacterial vaginosis, were diagnosed applying direct detection methods and specific culture isolation. Chlamydia trachomatis (antigen detection), Ureaplasma urealyticum and Mycoplasma hominis (culture) were also studied in part of the population. Patient care increased steadily from 1997 and there was an increase of 2.1 times from the first semester to the last one in 1998. Bacterial vaginosis was the most prevalent disease in the adult group, with 23.8%; followed by Candida spp 17.8%; S. agalactiae 5.6%; T.vaginalis 2.4%. In 50.3% of total adult cases neither bacterial vaginosis or presence of any sought microorganisms, was detected. In the adolescents group the most frequent detection was Candida spp with a 29.7%; bacterial vaginosis in 17.8%; followed by S. agalactiae 3.6%, T.vaginalis 2.4%. Also in this group on an important number of cases, 46.4%, none bacterial vaginosis or the presence of the sought microorganism were found. In some of the adult group, C. trachomatis (7/400) 1.76%, U. urealyticum (209/340) 61.4% and M. hominis (45/272) 16.5% were detected. Bacterial vaginosis and Candida spp prevalence is important in both groups. The absence of N. gonorrhoeae and lower prevalence of T. vaginalis and C. trachomatis is remarkable. A high prevalence of U. urealyticum and M. hominis were also detected, but the actual pathogenic role in adult women is still under discussion. The significant

Uno de ellos está sometido a agricultura permanente y el otro conserva un pastizal natural bajo pastoreo y quemas no programados. Este último sector presentó en promedio una densidad de 70.000 sem m-2 contra 36.720 sem m-2 en el primero. La representación de semillas de especies nativas se redujo notablemente en el ambiente agrícola. Stipa caudata con 31360 sem m-2 resultó la especie más abundante en el pastizal. En el ambiente de cultivo, su densidad se redujo a 9940 sem m-2 y fue superada por Chenopodium album con 10560 sem m-2. La similitud en la composición del banco fue de 55% en términos cualitativos y 27% en términos cuantitativos. Estos resultados evidencian que, en el área de estudio, el reemplazo del pastizal natural por agricultura reduce notoriamente las reservas de semillas y modifica la composición cualitativa y cuantitativa del banco con una elevada pérdida en la proporción de especies nativas.In order to evaluate the impact of agriculture on the potential flora of grasslands of the sierras of Azul (Buenos Aires Province, Argentina, the soil seed bank in the top 20 cm from two adjacent areas on the first foothill spurs were compared.

    As a consequence of YF outbreaks that hit Brazil, Argentina, and Paraguay in 2008-2009, a significant demand for YF vaccination was subsequently observed in Argentina, a country where the usual vaccine recommendations are restricted to provinces that border Brazil, Paraguay, and Bolivia. The goal of this paper is to describe the adverse events following immunization (AEFI) against YF in Argentina during the outbreak in the northeastern province of Misiones, which occurred from January 2008 to January 2009. During this time, a total of nine cases were reported, almost two million doses of vaccine were administered, and a total of 165 AEFI were reported from different provinces. Case study analyses were performed using two AEFI classifications. Forty-nine events were classified as related to the YF vaccine (24 serious and 1 fatal case), and 12 events were classified as inconclusive. As the use of the YF 17D vaccine can be a challenge to health systems of countries with different endemicity patterns, a careful clinical and epidemiological evaluation should be performed before its prescription to minimize serious adverse events.

    This paper reports that like so many other countries, Argentina is in the throes of privatization and restructuring of its economic programs. This has had a direct effect on the LPG industry. Argentina is a country with many natural resources. However, natural gas and crude, while present, are not in abundance. Imports of these and their associated products are needed to satisfy the growing need of the population from time to time. This is especially true with LPGs. Production of the fuel averages about 1 million tons, not enough to satisfy internal needs in the winter but enough to permit some exports in the summer to nearby Brazil. The Country's Congress approved a plan to sell-off or lease parts of the natural gas distribution network and other businesses of Gas del Estado. Subsequent new legislation has called for ten new natural gas distribution zones. Included in the sell-off is the company's propane distribution division. What is left of Gas del Estado and YPF will become a corporation in the true sense of the word. Stocks in YPF are to be sold to the public

    Due to the absence of alerts or volcanic impacts during 60 years (from 1932, Quizapu-Descabezado Grande -one of the major eruptions of the XX Century- until 1991 Hudson eruption) there was mild remembrance of volcanic hazards in the collective memory of the Argentina citizens. Since then and until April 2015, the social perception changed according to different factors: age, location, education, culture, vulnerability. This variability produces a maze of challenges that go beyond the scientific knowledge. Volcanic health hazards began to be understood in 2008 after the eruption of Chaiten volcano. The particle size of ashfall (concern on epidemiological monitoring. In 2011 the volcanic complex Puyehue - Cordon Caulle eruption produced ashfall through plumes that reached densely populated cities like San Carlos de Bariloche and Buenos Aires. Farther away in South Africa and New Zealand ash plumes forced airlines to cancel local and international flights for several weeks. The fear of another eruption did not wait long when Calbuco volcano started activity in April 2015, it came at a time when Villarrica volcano was also in an eruptive phase, and the SERNAGEOMIN Chile, through the Observatory OVDAS of the Southern Andes, faced multiple natural disasters at the same time, 3 volcanoes in activity, lahars, pyroclastic flows and floods in the North.

    Argentina is currently undergoing an intensive development of coastal-oriented tourism due to the temperate climate and coastal sceneries of the Southwestern Atlantic and particularly its wide ocean-open sandy beaches, which may turn into an important contributor of marine debris to the beaches. This study was designed to assess at four spatial scales (i) the variation of the abundance and mass of marine debris and (ii) the composition and sources of these items in sandy-tourist beaches of coastal zones of the province of Buenos Aires, in northern Argentina. The abundance and mass of marine debris shifted between sampling localities (separated by ~1.5×10 5 m) and beaches (~3×10 4 m). Debris was primarily from recreational and fishing activities and over 20mm in size. Tackling the complications associated with marine debris in northern Argentina may include intensive educational and advertising campaigns oriented chiefly to beach users and fisherman.

    Full Text Available Tuberculosis (TB remains a cause of illness and death across the world, especially in developing countries and vulnerable population groups. In 2013, 1.5 million died from the disease worldwide. In Argentina, the largest proportion of TB-related deaths occurred in the northern provinces. Several international studies reported that TB mortality was related to the presence of certain comorbidities and socio-demographic characteristics. Our aim was to investigate the main risk factors associated with TB mortality in adults from six provinces in Argentina, especially those with higher TB mortality rates. A retrospective case-control study was conducted. It included all patients of =18 years with clinical and/or bacteriological TB diagnosis who underwent treatment from January 1st, 2012 to June 30th, 2013. Socio-demographic, clinical and bacteriological variables were surveyed. Information on 157 cases and 281 controls was obtained. Patients reported as deceased to the TB Control Program were considered cases, and those whose treatment result was reported as successful in the same time period were considered controls. For 111 deaths, the average time elapsed between the start of treatment and death was 2.3 months; median: 1. TB-related mortality was associated with poor TB treatment adherence (OR: 3.7 [1.9-7.3], p: 0.000, AIDS (OR: 5.29 [2.6-10.7], p: 0.000, male gender (OR: 1.7 [1.1-2.5], p: 0.009, belonging to indigenous people (OR: 7.2 [2.8-18.9], p:0. 000 and age = 50 (OR: 2.2 [1.4-3.3], p: 0.000. By multivariate analysis the two first associations were confirmed. This study sets up the basis for planning inter-program and inter-sector work to accelerate the decline in the inequitable TB mortality.

    Since 2007, more than half of the world's population live in urban areas. Urban atmospheres are dominated by pollutants associated with vehicular emissions. Transport emissions are an important source of non-methane volatile organic compounds (NMVOCs) emissions, species of high interest because of their negative health effects and their contribution to the formation of secondary pollutants responsible for photochemical smog. NMVOCs emissions are generally not very well represented in emission inventories and their speciation presents a high level of uncertainty. In general, emissions from South American countries are still quite unknown for the international community, and usually present a high degree of uncertainty due to the lack of available data to compile emission inventories. Within the Inter-American Institute for Global Change Research (IAI, www.iai.int) projects, UMESAM (Urban Mobile Emissions in South American Megacities) and SAEMC (South American Emissions, Megacities and Climate, http://saemc.cmm.uchile.cl/), the effort was made to compute on-road transport emission inventories for South American megacities, namely Bogota, Buenos Aires, Lima, Sao Paulo and Santiago de Chile, considering megacities as urban agglomerations with more than 5 million inhabitants. The present work is a continuation of these projects, with the aim to extend the calculated NMVOCs emissions inventory into the individual species required by CTMs. The on-road mobile sector of the metropolitan area of Buenos Aires (MABA), Argentina, accounted for 70 Gg of NMVOCs emissions for 2006, without considering two-wheelers. Gasoline light-duty vehicles were responsible for 64% of NMVOCs emissions, followed by compressed natural gas (CNG) light-duty vehicles (22%), diesel heavy-duty vehicles (11%) and diesel light-duty vehicles (7%). NMVOCs emissions were speciated according to fuel and technology, employing the European COPERT (Ntziachristos & Samaras, 2000) VOCs speciation scheme for

    Freshwater habitats are important elements within urban green space and they are endangered by various types of human activity. With the aim to increase the knowledge about species biodiversity in urban ecosystems, we characterised the assemblages of aquatic insects in four permanent man-made ponds in Buenos Aires city (Argentina) during a 1-year period. We recorded 32 species with Sigara spp. (Hemiptera) as the most abundant. The removal of aquatic vegetation from the studied ponds may have affected both the establishment and permanence of the insect community. Swimmers were the dominant group in the studied sites, followed by burrowers and sprawlers, and only a few strictly climbers were collected. Therefore, all sampled ponds were dominated by collectors (principally gatherers), secondarily by predators and only few shredders were detected, which was much affected by the removal of macrophytes. Non-parametric abundance indexes estimated a number of species very close to the observed number in each site. Conversely, the incidence indexes estimated more species because there were many more taxa present only in one sample than those represented by few individual in a sample. Our data provides some insights on the community of man-made ponds that can improve the management of these aquatic urban habitats. Considering that macrophytes affect animal assemblages due to their role as physical structures that increase the complexity or heterogeneity of habitats, they should not be removed by authorities in order to promote biodiversity.

    Groundwater pollution is a major concern in peri-urban environments. Thus, water quality is being investigated at several domestic wells in Brandsen, 70 km south of Buenos Aires, Argentina. To present, about 20 water sources were sampled in orchards and small farms of the area. There is limited data about the wells construction, although collected information suggests that groundwater is derived from the superficial sandy loams of the Pampean Aquifer. Samples were analysed for major inorganic elements using ion chromatography and ICP-MS. Titration was used to estimate alkalinity. Physical characteristics (EC, pH, temperature) were measured on site. Results show that groundwater pH ranges from 6.5 to 7.8, with a specific conductance of 180 to 255 mS/m. A peak of 360 mS/m in one horticultural parcel is associated to local NO3- concentrations up to 140 mg/L. This value exceeds the maximum recommendations set by the WHO (50 mg/L). Considering that fertilizer inputs in that property are negligible, the high levels of NO3- might be attributed to effluents from a neighbour septic tank. An increase in NO3- (>150mg/L) was also detected in two conventional farms. This increase correlates to elevated SO42- concentrations (>300 mg/L) suggesting thus, fertilizers percolation into the saturated zone. The leaching of these fluids might be exacerbated by irrigation during new planting, and accumulations of fertilizer-solids in the root zones from previous seasons. Chloride concentrations average ~90 mg/L and would not pose a threat to health at the moment. Its main origin would be related to connate waters in the loam matrix, although some anthropogenic inputs might occur in the previously described farms. In general, the rest of the analysed elements fall within acceptable levels for drinking purposes as well. Nevertheless, further work is still necessary to better define the fate of the potential harmful elements and assess seasonal variations in water quality.

    In this paper, evidence of paleoearthquake-induced soft-sediment deformation structures associated with the Magallanes-Fagnano Fault System in the Isla Grande de Tierra del Fuego, southern Argentina, has been identified. Well-preserved soft-sediment deformation structures were found in a Holocene sequence of the Udaeta pond. These structures were analyzed in terms of their geometrical characteristics, deformation mechanism, driving force system and possible trigger agent. They were also grouped in different morphological types: sand dykes, convolute lamination, load structures and faulted soft-sediment deformation features. Udaeta, a small pond in Argentina Tierra del Fuego, is considered a Quaternary pull-apart basin related to the Magallanes-Fagnano Fault System. The recognition of these seismically-induced features is an essential tool for paleoseismic studies. Since the three main urban centers in the Tierra del Fuego province of Argentina (Ushuaia, Río Grande and Tolhuin) have undergone an explosive growth in recent years, the results of this study will hopefully contribute to future analyses of the seismic risk of the region.

    Polymorphisms at Major Histocompatibility Complex (MHC) genes have been associated with resistance/susceptibility to infectious diseases in domestic animals. The aim of this investigation was to evaluate whether polymorphisms of the DRA gene the Equine Lymphocyte Antigen is associated with susceptibility to Equine Arteritis Virus (EAV) infection in horses in Argentina. The equine DRA gene was screened for polymorphisms using Pyrosequencing® Technology which allowed the detection of three ELA-DRA exon 2 alleles. Neither allele frequencies nor genotypic differentiation exhibited any statistically significant (P-values=0.788 and 0.745) differences between the EAV-infected and no-infected horses. Fisher's exact test and OR calculations did not show any significant association. As a consequence, no association could be established between the serological condition and ELA-DRA.

    Full Text Available This is a first approach to the application of virtual reconstruction techniques of a colonial house. In Argentina it is still uncommon to perform 3D modeling of archaeological sites and especially in historical archeology. As a first step, we used the Google SketchUp to model the country house located on the banks of the Río de la Plata (Buenos Aires. It has historical significance because it belonged to a Spanish councilman, housed hundreds of slaves and was the place where stayed the troops that carried out the Second British Invasion of Buenos Aires. In this case, the 3D modeling was useful for evaluating the future excavationa and activities of preservation of cultural heritage.

    The aim of this study is to measure in two samples of Sardinian immigrants in Buenos Aires and representatives of the population in Sardinia the prevalence of depressive symptoms at the time of an economic crisis in Sardinia and to compare these results with those collected at the time of a similar crisis in Argentina more than 10 years before. Observational study. The associations of Sardinian immigrants in Buenos Aires provided the lists of families of Sardinian origin. A random sample of one fifth of registered families was selected. The sample of a study carried out in Sardinia was used as the control. The results were compared with those of the previous study performed in 2001-2002. The Patient Health Questionnaire (PHQ9) was used for the screening of depression. The Sardinian immigrants show a lower rate of scoring positively on PHQ9 (i.e. less risk of being depressed) and reach statistical significance after standardization (8.7% vs. 13.1%, P = 0.046). Young women (≤40) are at higher risk. On the contrary, the risk of depression was higher in Sardinian immigrants in Argentina during the 2001-2002 crises. The study indicates a risk for depressive episodes linked to the fallout of the economic crisis (in Argentina in 2001-2002, in Sardinia in 2015) and specifically more in females than in males. Due to the associated socio-demographic risk factors, these results could be interpreted as due to an increase in non-bipolar depression.

    The morphologic features of Talaromyces udagawae Stolk and Samson are here described and illustrated. This teleomorphic Ascomycota fungus was isolated from soil obtained in Buenos Aires province (Argentina) from beneath a human cadaver in an advanced state of decomposition. After washing and serial dilution of the soil along with moist-chamber techniques for fungal cultivation, T. udagawae formed very restricted colonies of bright yellow color on different growth media with 8-ascospored asci. The ascospores were ellipsoidal and ornamented. The anamorphic state was not observed. Molecular-genetic techniques identified the species. The present record is the first of the species in Argentina, pointing it as a tool to identify soils where cadaver decomposition occurs. Copyright © 2015 Asociación Argentina de Microbiología.

    Cessation of tobacco use has the potential to provide the greatest immediate benefits for tobacco control. Understanding the social determinants of smoking cessation is an essential requirement for increasing smoking cessation at the population level. The purpose of this study was to analyze the socio-economic dimensions associated with cessation success among adults in Argentina and Uruguay. Data from the Global Adult Tobacco Survey (GATS), a cross-sectional, population-based, nationally representative survey conducted in Argentina (n=5,383) and Uruguay (n=4,833) was utilized. Univariable and multivariable logistic regression analyses with results being presented as odds ratios (OR) with 95% confidence intervals were applied to study differences among those respondents who sustained smoking abstinence (≥1 year) and those who continued smoking. The GATS study revealed that social gradients in tobacco quitting exist in Argentina and Uruguay. Being aged 25-34, particularly men in Uruguay, women in Argentina, low educated men in Argentina and having a lower asset index were associated with reduced odds for quitting. Factors that are driving differences in smoking cessation between diverse social groups in Latin America countries need to be considered when implementing relevant interventions to ensure tobacco control strategies work effectively for all population segments.

    Sarmiento believed that Copernican astronomy was one of the critical scientific disciplines to the formation of a "modern" citizen. In this work, we shall study astronomical science from two points of view: from the scientific knowledge and the educational presentation of such knowledge. Our study will address in Argentina in 19th century, starting from the initiative of Bernardino Rivadavia in 1821, who founded an astronomic observatory at Buenos Aires, until the first activities of the observatories at Córdoba and La Plata. On both lines, scientific and educative, we shall analyze the influence of positivist ideas. We shall highlight epistemological differences between both observatories, Córdoba's based on French positivism and La Plata's based on German positivism. We shall also show the different attitude of both observatories towards education. We shall see the way in which positivist ideas had great relevance in the training of elementary school teachers. We shall also establish the relevant influence of the socio-historical context over the astronomical development, and show that astronomy was a fundamental social factor at Argentina history. Domingo F. Sarmiento consideraba que la astronomía copernicana era una de las disciplinas científicas fundamentales para la conformación de un ciudadano "moderno". En este trabajo estudiaremos la ciencia astronómica desde dos vertientes: la referida específicamente al conocimiento científico y aquella vinculada con la presentación educativa de dicho conocimiento. Nuestro estudio se desarrollará en Argentina durante el siglo XIX, desde la iniciativa de Bernardino Rivadavia en 1821, de establecer en Buenos Aires un observatorio astronómico, hasta las primeras actividades de los observatorios de Córdoba y de La Plata.

    The current situation of nuclear medicine in Argentina, taking into account the facilities, their equipment and human resources available is presented in this paper. A review and analysis of the equipment, including technical characteristics and a survey of the professionals and technicians of the area, was carried out. In Argentina, there are 266 centers of nuclear medicine distributed all over the country. The operating licenses are granted by the Nuclear Regulatory Authority (Autoridad Regulatoria Nuclear - ARN). Forty four percent of the installed equipment are SPECT of 1 or 2 heads and 39,4 % are gamma camera. Besides, there are eleven PET operating in Argentina. There are 416 nuclear medicine physicians with individual permit for diagnostic purposes and 50% of them has also individual permit for treatment purposes. With the purpose of analyzing the regional distribution of the available resources in nuclear medicine, the country was divided into 7 geographical regions: City of Buenos Aires, Province of Buenos Aires, Pampa, Cuyo, Northeast, Northwest and Patagonia. From the analysis of the gathered information it is possible to conclude that the nuclear medicine equipment as well as the personnel present an irregular distribution, with a major concentration in the City of Buenos Aires and Province of Buenos Aires. The Northeast region presents the lowest number of Nuclear Medicine centers and the Patagonia region has the lowest number of medicine nuclear physicians with individual permits. The number of SPECT and gamma cameras is 7,3 per million of inhabitants. The information about the available resources in nuclear medicine presented in this paper and its comparison with the international information available provide elements for a better planning of the future activities in the area not only for the operators but also from the regulatory point of view.

    This study examined whether healthier family dynamics were associated with higher personal strengths of resilience, sense of coherence, and optimism among dementia caregivers in Argentina. Caregivers are usually required to assist individuals with dementia, and family members have typically fulfilled that role. Personal strengths such as resilience, sense of coherence, and optimism have been shown to protect caregivers from some of the negative experiences of providing care, though the family-related variables associated with these personal strengths are largely unknown. Hierarchical multiple regressions investigated the extent to which family dynamics variables are associated with each of the caregiver personal strengths after controlling for demographic and caregiver characteristics. A sample of 105 caregivers from Argentina completed a set of questionnaires during a neurologist visit. Family dynamics explained 32% of the variance in resilience and 39% of the variance in sense of coherence. Greater family empathy and decreased family problems were uniquely associated with higher resilience. Greater communication and decreased family problems were uniquely associated with higher sense of coherence. Optimism was not found to be significantly associated with family dynamics. These results suggest that caregiver intervention research focused on the family may help improve caregiver personal strengths in Argentina and other Latin American countries. PMID:27413574

    Varni, Marcelo R.; Usunoff, Eduardo J.

    A three-dimensional modular model (MODFLOW) was used to simulate groundwater flow in the Azul River basin, Buenos Aires Province, Argentina, in order to assess the correctness of the conceptual model of the hydrogeological system. Simulated heads satisfactorily match observed heads in the regional water-table aquifer. Model results indicate that: (1) groundwater recharge is not uniform throughout the region but is best represented by three recharge rates, decreasing downgradient, similar to the distribution of soils and geomorphological characteristics; and (2) evapotranspiration rates are larger than previous estimates, which were made by using the Thornthwaite-Mather method. Evapotranspiration rates estimated by MODFLOW agree with results of independent studies of the region. Model results closely match historical surface-flow records, thereby suggesting that the model description of the aquifer-river relationship is correct. Résumé Un modèle modulaire tridimensionnel (MODFLOW) a été utilisé pour simuler les écoulements souterrains dans le bassin de la rivière Azul (Province de Buenos Aires, Argentine), dans le but d'évaluer la justesse du modèle conceptuel du système hydrogéologique. La piézométrie simulée s'ajuste de façon satisfaisante à celle observée pour l'ensemble de la nappe. Les résultats du modèle indiquent que: (1) la recharge de la nappe n'est pas uniforme sur toute la région, mais qu'elle est mieux approchée par trois valeurs différentes, décroissant vers l'aval-gradient, en suivant la même distribution que les sols et les caractéristiques géomorphologiques et (2) l'évapotranspiration est nettement plus importante que prévu initialement à partir de la méthode de Thornthwaite-Mather. Les valeurs d'évapotranspiration fournies par MODFLOW concordent bien avec les résultats d'autres études portant sur la région. Les résultats du modèle reproduisent convenablement les chroniques de débit des écoulements de surface

    Full Text Available Debido a su rol como polinizador y productor de miel, la abeja Apis mellifera L. es considerado un insecto beneficioso. Si bien Argentina juega un papel de liderazgo en la producción de miel, existe un considerable vacío en el conocimiento acerca de las enfermedades de etiología protista que afectan las abejas en el país. La ameba Malpighamoeba mellificae Prell es un protista entomopatógeno que invade los túbulos de Malpighi de las abejas e interfiere con el proceso de excreción, debilitando al huésped y posiblemente facilitando la acción de otros patógenos. En esta contribución se presentan los primeros hallazgos de M. mellificae en Argentina y se brindan datos iniciales acerca de su frecuencia, intensidad de las infecciones, y co-ocurrencia con Nosema sp. Malpighamoeba mellificae se halló en dos de 36 localidades prospectadas: San Cayetano, al Sur de la provincia de Buenos Aires y San Carlos de Bariloche, en el Oeste de la provincia de Río Negro.Due to its role as a pollinator and honey producer, the honey bee Apis mellifera L. is considered a beneficial insect. Although Argentina plays a leading role in honey production, there is a considerable gap in knowledge regarding protistan diseases that affect honey bees in the country. The amoeba Malpighamoeba mellificae Prell is an entomopathogenic protist that invades the Malpighian tubules of honey bees and interferes with the excretory process, debilitating the host and possibly facilitating the action of other pathogens. In this contribution, we present the first reports of M. mellificae in Argentina, and provide some initial data about its frecuency, infection intensity, and co-occurrence with Nosema sp. Malpighamoeba mellificae was found in two out of 36 localities surveyed: San Cayetano, in southern Buenos Aires province, and San Carlos de Bariloche, in western Río Negro province.

Se identificaron rodales de Eucalyptus viminalis Labill. cuyas edades oscilaron entre 4 y 14 años. Se apearon 21 árboles con diámetros entre 9,2 y 32,5 cm. Se desarrollaron regresiones simples y múltiples y se estimó el volumen, la biomasa en ramas, hojas y fuste. Las ecuaciones de volumen de mejor comportamiento son basadas en modelos lineales en su forma normal, y el modelo más adecuado fue el que incorporó al d2 (R2 = 0,92. Para la estimación de la biomasa en hojas, ramas, copa y fuste se recomienda los modelos ln-ln que consideran el d y h o solo el d. El componente de la biomasa en hojas presentó una estimación más débil. La distribución de la biomasa en los individuos sigue el patrón de desarrollo que se encuentra en la bibliografía. La proporción de la biomasa en la copa disminuye con la edad, contrariamente a lo sucedido con el fuste.

    Full Text Available Snakes of the pseudoboine genera Clelia, which is probably polyphyletic, and Boiruna are distributed from southern Argentina, southern Brazil, and Uruguay northwards into central México. Six members occur in Paraguay and Argentina: B. maculata, Clelia bicolor, C. clelia, C. plumbea, C. quimi, and C. rustica. Historically, there has been taxonomic confusion among the larger species (B. maculata, C. clelia, C. plumbea, and C. rustica and between the small species (C. bicolor and C. quimi. All of the species except C. rustica have distinct ontogenetic color changes. Species can be distinguished on the bases of size, color, hemipenial spines, and loreal, supralabial, and ventral scale counts. Much of the morphological evolutionary differentiation in Boiruna and Clelia seems to have taken place in the snout region, as evidenced by the differing proportions of the scales of the loreal region. Boiruna maculata has the widest ecological amplitude. It is broadly distributed in most vegetation types north of the 38th parallel in central Argentina, being absent only from the deltaic sediments of Buenos Aires Province, Argentina and the broad valleys and rolling hills of eastern Paraguay. Clelia bicolor is most common in the Paraguay and Paraná river valleys, with a few records from the Andean foothills in northern Argentina. Clelia clelia is distributed along the Río Paraguay and the lower Paraná, and is also found throughout much of eastern Paraguay. Clelia plumbea is apparently parapatric with C. clelia along the Río Paraná in southeastern Paraguay and Misiones Province, Argentina. The ranges of C. quimi to the east and C. bicolor in the west about in this same region without apparent overlap. There are no vouchered records of Clelia rustica from Paraguay. In Argentina, it is a species of temperate climates; north of the 30th parallel, it occurs in the Andean foothills and the wet forests of Misiones Province. Southwards, it is widely distributed

    Full Text Available Japanese migration to Argentina started in the early Twentieth Century, with the arrival of Japanese men from other Latin American countries and did not stop until the 60’s even though as time passed the composition of the immigrant group changed and so did their objectives. Japanese immigrants soon created voluntary associations where they gathered, a trend that still survives to these days. The different kind of associations they created, their aims and later development as well as their relationship to the Japanese government, are broached in this paper. It focuses on the changes Japanese associations have suffered along the process, a as support devices for young men that arrived as dekaseguis in early times, and whose stay was extended indefinitely, b during the Second World War crisis c with the arrival of Japanese newcomers during the postwar period, d attending to the cases of Japanese migrants arriving from the Dominican Republic, Paraguay and Bolivia; and, finally, dealing with the dilemma aroused by the decision to settle definitively versus the desire to preserve Japanese traditions and identity

    1977-08-01

    Argentina is a predominantly lowland area of 2,789,240 square kilometers. The capital is Buenos Aires. The entire length of Argentina is bordered on the west by the Andes Mountains. Tile Northwest Andes-Piedmont region consists of deep valleys containing salt basins and volcanoes, and is an earthquake zone. Patagonia, in the south, is essentially an arid region of windy plateaus and valleys. The southern Andes are narrower and lower than the northern Andes and in the extreme south contain glaciers and ice fields. The east-central plain (Pampa) of Argentina has dry and humid sectors and contains most of the population. The largest rivers are chiefly in the northeast, many having only seasonal flow. There has been extensive surface and subsurface exploration for uranium in Argentina for over 20 years. Although most of the work has been performed by the CNEA, advisors from the U.S. and from the IAEA have also taken part. Private industry has been involved, but apparently only on a small scale. In the OECD report of 1970, it was stated that 400,000 square kilometers of Argentina appear very favorable for uranium while an additional 900,000 square kilometers offer fair possibilities. Uranium exploration to date suggests that sandstones of Permian and Cretaceous ages exposed in Western Argentina in the Cordillera are very promising for discovery of new deposits. Past CNEA estimates have indicated that there is considerable hope for new discoveries in those areas where reserves are now known. In addition to the known uraniferous provinces which are indeed favorable for further exploration, there are several other large areas that warrant attention. There are, for example, in the Santa Cruz area of about 15,500 square kilometers Cretaceous and Tertiary sediments with favorable facies for uranium deposition. In the Patagonia Cordillera, Jurassic, Cretaceous, and Tertiary sediments are of interest for prospecting, These rocks contain carbonaceous material and have been

    The current situation of nuclear medicine in Argentina, taking into account the facilities, their equipment and human resources available is presented in this paper. A review and analysis of the equipment, including technical characteristics and a survey of the professionals and technicians of the area, was carried out . In Argentina, there are 292 centers of nuclear medicine distributed all over the country. The operating licenses are granted by the Nuclear Regulatory Authority. Forty percent of the installed equipment are SPECT of 1 or 2 heads and 40 % are gamma camera. Besides, there are two PET operating in Argentina. There are 402 nuclear medicine physicians with individual permit for diagnostic purposes and 50% of them has also individual permit for treatment purposes. With the purpose of analyzing the regional distribution of the available resources in nuclear medicine, the country was divided into 7 geographical regions: City of Buenos Aires, Province of Buenos Aires, Pampeana, Cuyo, Northeast, Northwest and Patagonia. From the analysis of the gathered information it is possible to conclude that the nuclear medicine equipment as well as the personnel presents an irregular distribution, with a major concentration in the City of Buenos Aires and Province of Buenos Aires. The Northeast region presents the lowest number of Nuclear Medicine centers and the Patagonia region has the lowest number of nuclear medicine physicians with individual permits. The number of SPECT and gamma cameras is 8,65 per million of inhabitants. The information about the available resources in nuclear medicine presented in this paper and its comparison with the international available information provide elements for a better planning of the future activities in the area not only for the operators but also from the regulatory point of view.

    Full Text Available Backgound and Objectives: Individuals living in cities increasingly spend more time indoors in air-conditioned environments. Air conditioner contamination can be caused by the presence of aerosols from the external or internal environment, which may be associated with disease manifestations in patients present in this type of environment. Therefore, the aim of this review was to assess the air quality in air-conditioned hospital environments as a risk factor for hospital-acquired infections – HAI – as the air can be a potential source of infection, as well as assess the exposure of professionals and patients to different pollutants. Material and Methods: A literature review was performed in the LILACS, MEDLINE, SCIELO, SCIENCE DIRECT databases, CAPES thesis database and Ministry of Health – Brazil, including studies published between 1982 and 2008. The literature search was grouped according to the thematic focus, as follows: ventilation, maintenance and cleaning of systems that comprehend the environmental quality standard. Discussion and Conclusion: Outbreaks of hospital-acquired infections associated with Aspergillus, Acinetobacter, Legionella, and other genera such as Clostridium and Nocardia, which were found in air conditioners, were observed, thus indicating the need for air-conditioning quality control in these environments.

    Full Text Available Abstract We describe the genetic diversity of currently transmitted strains of HIV-1 in men who have sex with men (MSM in Buenos Aires, Argentina between 2000 and 2004. Nearly full-length sequence analysis of 10 samples showed that 6 were subtype B, 3 were BF recombinant and 1 was a triple recombinant of subtypes B, C and F. The 3 BF recombinants were 3 different unique recombinant forms. Full genome analysis of one strain that was subtype F when sequenced in pol was found to be a triple recombinant. Gag and pol were predominantly subtype F, while gp120 was subtype B; there were regions of subtype C interspersed throughout.

    Full Text Available Temporary ponds represent special environments that are inhabited by organisms adapted to changing environmental conditions. Ciliates are able to survive complete loss of water in these transient habitats through cyst formation. However, ciliates from the Neotropical region in general have been poorly studied with modern techniques. The main goal of this study is to describe the ciliates in dried sediments of a temporary pond from Buenos Aires Province, Argentina, through sampling efforts that were performed 2003-2005. Soil samples were obtained during drought phases and re wetted in laboratory to establish raw and enriched cultures. Ciliates were then studied both in vivo and after impregnation with protargol. In this study, we present 4 new records for Argentina (Gonostomum affine (Stein, 1859 Sterki, 1878, Stylonychia bifaria (Stokes, 1887 Berger, 1999, Pleurotricha lanceolata (Ehrenberg, 1835 Stein, 1859, Meseres corlissi Petz and Foissner, 1992, 1 for South America (Blepharisma americanum (Suzuki, 1954 Hirshfield, Isquith and Bhandary, 1965, and 2 for the Neotropical Realm (Gonostomum strenuum (Engelmann, 1862 Sterki, 1878, Stylonychia lemnae Ammermann and Schlegel, 1983.Los cuerpos de agua temporarios son ambientes particulares que se encuentran habitados por organismos adaptados a condiciones fluctuantes.

    Full Text Available Resumen La cuenca del río Reconquista es una de las tres grandes cuencas de la Región Metropolitana de Buenos Aires (Argentina gravemente afectada por las inundaciones y por la contaminación. En tanto pieza territorial de la ciudad metropolitana, la cuenca Reconquista fue abordada en los documentos de planificación urbana que se elaboraron para la región durante la segunda mitad del siglo XX: el Plan Regulador de Buenos Aires, el Esquema Director Año 2000, el Estudio del Sistema Metropolitano Bonaerense y el Proyecto 90. Independientemente de que se hayan concretado o no, esas instancias de planificación ilustran las formas de pensar y operar en la cuenca, como un ámbito dentro de la ciudad, como un problema de alcance metropolitano y como una propuesta de transformación territorial, en tres momentos: el de las inundaciones y la hidráulica, el del medio ambiente y la calidad de vida, y el de la ecología y el paisaje, donde cambian las relaciones que se establecen entre la urbanización, el urbanismo y las cuencas hídricas.

    Full Text Available El partido de Benito Juárez, ubicado en el centro-sur de la provincia de Buenos Aires (Argentina, es ambientalmente heterogéneo y productivamente mixto, con tradición predominantemente ganadera. A fin de evaluar las tendencias en el uso de la tierra, se describió la evolución de los diferentes rubros productivos y su diversidad durante el periodo 1998-2007, sobre la base de una selección de 30 establecimientos. El pastizal natural ocupó la mayor proporción de superficie promedio en el período considerado, pero reflejó una pérdida de 23 puntos porcentuales compensada sólo parcialmente por un aumento de pasturas perennes. La suma de ambos recursos forrajeros evidenció una caída en la superficie destinada a ganadería y, al final del periodo, fue ligeramente superada por la superficie destinada a cultivos anuales. Entre éstos, la soja fue el cultivo con mayor expansión pero su participación relativa alcanzó sólo el 11,02%. Paralelamente, la diversidad productiva, estimada mediante una adaptación del índice de diversidad de Shannon, aumentó 30,84%. Aunque es evidente el avance de cultivos anuales en desmedro de pastizales naturales, el reemplazo parcial de estos últimos por pasturas perennes y el aumento en la diversidad productiva limitan los riesgos ambientales potenciales, puestos de manifiesto en otras regiones del país.Benito Juarez county, in the central-south Buenos Aires province (Argentina, is environmentally and productively heterogeneous, with predominance of cattle farming.

    To determine human immunodeficiency virus (HIV) seroprevalence in a sample of men who have sex with men (MSM) in Buenos Aires City and to identify risk factors associated with HIV type 1 infection. Participants were invited to receive HIV counselling and testing at "NEXO" (a gay non-governmental organization) by means of informative leaflets distributed in gay nightclubs, porno cinemas, gymnasiums, and in the streets. During the encounter, the study was explained by a trained social worker and individuals were invited to volunteer for the study. Diagnosis of HIV was performed using two screening tests and Western Blot assay was used as confirmatory. Human immunodeficiency virus was detected in 96 (13.8%; 95% CI: 11.4-16.7) of 694 MSM. Fourteen (14.6%) of the 96 HIV-positive MSM were already aware of their HIV serostatus. In univariate analysis, HIV-1 infection (odds ratio [OR] >1.5) was found to be associated with older age (30-39 years), being unemployed, a previous sexually transmitted disease (STD) history, and having an HIV-positive partner. Cocaine consumption and irregular use of condoms with occasional partners were also found to be risk factors. In multivariate logistic regression analysis, being unemployed (OR = 3.42; 95% CI: 1.17-9.99) and having an HIV-positive partner (OR = 2.67; 95% CI: 1.09-6.52) remained significant risk factors. The high HIV-1 prevalence observed suggests an urgent need for implementation of effective prevention campaigns. This represents the first cross-sectional epidemiological study of HIV among the high-risk group of MSM in Argentina.

    Full Text Available La cuenca del arroyo Pescado Castigado se encuentra localizada en el Sureste de la provincia de Buenos Aires, Argentina. La peculiaridad de esta cuenca de llanura radica básicamente en su morfología poco definida, puesto que provoca que la red de drenaje sea muy versátil y dinámica. Esto afecta a la principal actividad económica: la agricultura y la ganadería a través de la cantidad de agua disponible, cantidad de superficie anegada o con erosión hídrica, hidromorfismo y halomorfismo. El área de estudio presenta cuatro unidades hidrográficas, la primera se caracteriza porque la escorrentía es laminar, la segunda presenta sistemas anárquicos de disipación o derrames areales, la tercera es un sistema mixto lineal y areal y la cuarta es un área poco inundable y anegable que presenta problemas de salinización. El objetivo de este trabajo es analizar los rasgos geomorfológicos de la cuenca que pueden estar asociados al funcionamiento de la escorrentía en estas cuatro unidades.

    In Argentina, unsafe abortions are the primary cause of maternal mortality, accounting for 32% of maternal deaths. During reform of the National Constitution in 1994, the women's movement effectively resisted the reactionary government/church position on abortion. Health professionals, including obstetrician-gynaecologists, played conflicting roles in this debate. This article presents results from a study carried out in 1998-1999 of the views of 467 obstetrician-gynaecologists from public hospitals in Buenos Aires and its Metropolitan Area, focus group discussions with 60 of them, and interviews with heads of department from 36 of the hospitals. The great majority believed abortion was a serious public health issue; that physicians should provide abortions which are not illegal; that abortion should not be penalized to save the woman's life, or in cases of rape or fetal malformations; and that women having illegal abortions and abortion providers should not be imprisoned. Some 40% thought abortion should not be penalized if it is a woman's autonomous decision. Those who were better disposed towards the de-penalization of abortion cited a combination of public health reasons and the need for social equity. The women's health and rights movement should do advocacy work with this professional community on women's needs and rights, given the prominent role they play in reproductive health care provision and in the public sphere.

    Soil microorganisms are vital for ecosystem functioning because of the role they play in soil nutrient cycling. Agricultural practices and the intensification of land use have a negative effect on microbial activities and fungal biomass has been widely used as an indicator of soil health. The aim of this study was to analyze fungal biomass in soils from southwestern Buenos Aires province using direct fluorescent staining and to contribute to its use as an indicator of environmental changes in the ecosystem as well as to define its sensitivity to weather conditions. Soil samples were collected during two consecutive years. Soil smears were prepared and stained with two different concentrations of calcofluor, and the fungal biomass was estimated under an epifluorescence microscope. Soil fungal biomass varied between 2.23 and 26.89μg fungal C/g soil, being these values in the range expected for the studied soil type. The fungal biomass was positively related to temperature and precipitations. The methodology used was reliable, standardized and sensitive to weather conditions. The results of this study contribute information to evaluate fungal biomass in different soil types and support its use as an indicator of soil health for analyzing the impact of different agricultural practices.

    In 1864, Lucio V. Mansilla y José Manuel Estrada created the Círculo Literario in Buenos Aires, Argentina, which endured until 1866. This cultural association shared the same concerns than other contemporary entities, also enacted by other men in the cultural life of Buenos Aires at that time. The Círculo Literario aspired to be an association that could gather politicians and men of culture, from different generations and political factions. The article examines the practices and initiatives of this cultural association, in a moment in which the Argentine culture was conceived as an open field for pioneers. The article evaluates the scope and the limits of this cultural entrepreneurship born outside from the State politics.

    High levels of scatter radiation in catheterization laboratories may lead to posterior subcapsular opacities in the lens of the staff. The international Retrospective Evaluation of Lens Injuries and Dose (RELID) was performed in Argentina for the first time in 2010 in the context of the congress of the Latin American Society of Interventional Cardiology (SOLACI) and recently, in 2014, was carried out for the second time (SOLACI-CACI 2014). The 2014 study included 115 participants: interventional cardiologists, technicians and nurses. Posterior subcapsular lens changes typical of ionizing radiation exposure were found in 91.5% of interventional cardiologists, in 77% of technicians and in 100% of nurses, according to the Merriam-Focht scale. This RELID study (Argentina 2014) has particular importance since it allowed the follow-up of 10 professionals evaluated in 2010. The results obtained in the study population highlight the importance of the availability and proper use of the elements of radiation protection, as well as staff training. (authors)

    The aim of this study was to describe an outbreak of Shigella sonnei that occurred in the city of Lujan, Buenos Aires, Argentina, in July 2012. Five individuals were affected after eating a hand-made Viennese-style pastry at a family gathering. All of them presented with fever, joint pain, chills and non-bloody diarrhea containing mucus. Stool cultures were performed in all cases and the samples taken from the pastry ingredients were analyzed microbiologically. S.sonnei was isolated and identified in all the patients involved as well as in the almond cream filling. The isolates were analyzed for determining the antimicrobial susceptibility and genetic profiles by pulsed field gel electrophoresis (PFGE). The results showed the genetic relationship among the isolates, confirming that the cases occurred due to the patients' exposure to the same source of infection, i.e., the almond cream. Being the almond cream an industrially-manufactured ingredient, an initial contamination could have been unlikely; however contamination might have occurred as a result of manipulation in the bakery.

Teachers’ reports to Yugoslav Embassy in Buenos Aires testify of Kingdom of Yugoslavia efforts to oppose assimilation and promote and strengthen “Yugoslav national unity”. The reports also describe general social circumstances of Yugoslav immigrants, show various details from their everyday life and contain valuable data on numerous political, economic, social and cultural problems of this diaspora in Argentina and their relationship with motherland. We believe that archive materials presented in this paper opens numerous questions which could be topics of separate researches. Some of them could be the following: To which extent the teachers’ reports represented the actual situation and to which they were shaped to match policy and expectations of Kingdom of Yugoslavia? What was the actual influence of teachers to spreading the “national unity” among immigrants? Have their work left trace in Yugoslav diaspora and in which way? Beside all of the open issues, it is certain that teachers’ reports contain valuable data on immigrants’ everyday life, curriculum, schooling conditions, relationship with motherland, etc. [Projekat Ministarstva nauke Republike Srbije, br. 47016: Interdisciplinarno istraživanje kulturnog i jezičkog nasleđa Srbije.

    Varroa destructor is considered one of the major threats for worldwide apiculture. Damage caused by varroa mite includes body weight loss, malformation and weakening of the bees. It was also suggested as the main cause associated with colony winter mortality and as an important vector for several honey bee viruses. Little is known about multiple factors and their interaction affecting V. destructor prevalence in apiaries from South America. The aim of this study was to identify risk factors associated with V. destructor prevalence in east-central Argentina. Parasitic mite infestation level and colony strength measures were evaluated in 63 apiaries distributed in 4 different regions in east-central Argentina in a cross sectional study. Data regarding management practices in each apiary were collected by means of a questionnaire. A mixed-effects logistic regression model was constructed to associate management variables with the risk of achieving mite infestation higher than 3%. Colonies owned by beekeepers who indicated that they did not monitor colonies after mite treatment (OR=2.305; 95% CI: 0.944-5.629) nor disinfect hives woodenware material (OR=2.722; 95% CI: 1.380-5.565) were associated with an increased risk of presenting high intensity infestation with V. destructor (>3%). On the other hand, beekeepers who reported replacing more than 50% of the queens in their operation (OR=0.305; 95% CI: 0.107-0.872), feeding colonies protein substitute containing natural pollen (OR=0.348; 95% CI: 0.129-0.941) and feeding colonies High Fructose Corn Syrup (HFCS) (OR=0.108; 95% CI: 0.032-0.364), had colonies that were less likely to have V. destructor infestations above 3%, than beekeepers who did not report using these management practices. Further research should be conducted considering that certain management practices were associated to mite infestation level in order to improve the sanitary condition in the colonies. Epidemiological studies provide key information to

    The assessment of baseline levels of atmospheric pollutants and the identification of polluted areas is a complex problem, as pollutant contents at a certain geographical location is usually a combination of contributions from various diverse sources, including long-range transport. Elemental chemical characterization of atmospheric pollutants is thus of great importance and Neutron Activation Analysis has proved to be a powerful technique for multielemental determination of trace elements in biomonitors and aerosols. The general objective of this project is to study the use of biomonitors, specially lichens, for evaluating pollutant levels over a wide geographic area of Argentina and for establishing baseline values and assessing time trends. Two lichen species (Usnea sp. and Ramalina ecklonii (Spreng.) Mey. and Flot) have been identified as suitable monitors of air pollution, with potential regional application at the central area of the country (province of Cordoba) and pilot studies have been initiated to test the practicability of sampling and sample collection. An area of approximately 40,000 km 2 will be covered by a sampling network, using in situ growing lichens. The distribution maps for the two selected species are already drawn and sampling of local soils will also be conducted. Current efforts at the Neutron Activation Analysis laboratory are put on assessing, for the selected lichen species, the influence of sample preparation methods on trace element concentrations. The use of other analytical techniques will allow the evaluation of the bioindicator chemical response and its relationship to different atmospheric quality levels. Source identification and apportionment will be done by statistical fingerprinting of the elemental concentrations, as sources of pollution are characterized by being composed of different mixtures of elements in different proportions. In this way and as a long-term objective, regional maps will be drawn showing the

    Three educational experiences are presented in this paper on the development of national and regional networks to incorporate renewable energy in curricular programmes. IASEE-Argentina, established in 1990 as the National Section of IASEE, the International Association for Solar Energy Education, was designated in 1993 as the Education Working Group of ASADES, the Argentine Association of Solar Energy. It holds annual meetings to coincide with the ASADES conference. Arquisur is a regional network established by Architectural Faculties of State Universities within the Mercosur Region, covering Argentina, southern Brazil, Paraguay and Uruguay, to promote exchange and development between the 19 faculties involved. A Working Group set up by Arquisur with members from four countries developed the programme for short post-graduate courses on bioclimatic design and rational energy use in buildings, which has been given in Argentina and Uruguay. Alfa-Built, a project supported by the European Union for promoting academic exchange in the field of energy efficient building is also introduced. This paper presents the development and initial results of these educational experiences. (author)

    Full Text Available BACKGROUND: The estimated prevalence of HCV infection in Argentina is around 2%. However, higher rates of infection have been described in population studies of small urban and rural communities. The aim of this work was to compare the origin and diversification of HCV-1b in samples from two different epidemiological scenarios: Buenos Aires, a large cosmopolitan city, and O'Brien, a small rural town with a high prevalence of HCV infection. PATIENTS AND METHODS: The E1/E2 and NS5B regions of the viral genome from 83 patients infected with HCV-1b were sequenced. Phylogenetic analysis and Bayesian Coalescent methods were used to study the origin and diversification of HCV-1b in both patient populations. RESULTS: Samples from Buenos Aires showed a polyphyletic behavior with a tMRCA around 1887-1900 and a time of spread of infection approximately 60 years ago. In contrast, samples from ÓBrien showed a monophyletic behavior with a tMRCA around 1950-1960 and a time of spread of infection more recent than in Buenos Aires, around 20-30 years ago. CONCLUSION: Phylogenetic and coalescence analysis revealed a different behavior in the epidemiological histories of Buenos Aires and ÓBrien. HCV infection in Buenos Aires shows a polyphyletic behavior and an exponential growth in two phases, whereas that in O'Brien shows a monophyletic cluster and an exponential growth in one single step with a more recent tMRCA. The polyphyletic origin and the probability of encountering susceptible individuals in a large cosmopolitan city like Buenos Aires are in agreement with a longer period of expansion. In contrast, in less populated areas such as O'Brien, the chances of HCV transmission are strongly restricted. Furthermore, the monophyletic character and the most recent time of emergence suggest that different HCV-1b ancestors (variants that were in expansion in Buenos Aires had the opportunity to colonize and expand in O'Brien.

    To ascertain lifetime prevalence of positivity to a screening questionnaire for bipolar disorders (BD) in Sardinian immigrants to Argentina and residents of Sardinia and assess whether such positivity affects quality of life (QoL) in either group. Our hypothesis is that screen positivity for BD may be more frequent in immigrants. Observational study. Subjects were randomly selected from the membership lists of associations of Sardinian immigrants in Argentina. A study carried out in Sardinia using the same methodology was used for comparison. The Mood Disorder Questionnaire was used to screen for mania/hypomania and the Short-Form Health Survey-12 to measure QoL. A higher prevalence of manic/hypomanic episodes was found in Sardinian immigrants to Argentina (p immigrants to Argentina and in residents of Sardinia. To the best of our knowledge, this is the first study to show a higher lifetime prevalence of manic/hypomanic episodes in a general-population sample of individuals who migrated to a foreign country. Our results are in agreement with the hypothesis that hyperactive/novelty-seeking features may represent an adaptive substrate in certain conditions of social change.

    Immunomodulatory effects of chemicals adsorbed to particles with aerodynamic diameter below 0.49 μm (PM 0.5 ) collected in winter 2001 at three sampling points (industrial area [LPIn], traffic-influenced urban area [LPCi], and control area [LPCo]) of La Plata, Argentina, were investigated. The sampling of particulate matter was carried out with high-volume collectors using cascade impactors. PM 0.5 -adsorbed compounds were hexane-extracted by accelerated solvent extraction. For immunological investigations, human peripheral blood lymphocytes were activated by phytohemagglutinin and exposed to dimethyl-sulfoxide dilutions of PM 0.5 -extracts for 24 h. Vitality/proliferation was quantified using MTT, released interferon-γ (IFN-γ) and interleukin-4 (IL-4) by ELISA. Cytokine production but not vitality/proliferation was significantly suppressed by all of the highest extract concentrations. Generally, suppression of IFN-γ by PM 0.5 -extracts was stronger than those of IL-4. Based on administered mass of PM 0.5 , all extracts suppressed IFN-γ production nearly uniform. Contrary, LPCi-extracts exerted maximum IFN-γ suppression based either on air volume or regarding PM 0.5 -adsorbed PAH. Also the ranking of PM 0.5 -associated effects on IL-4 production differs in dependence of the chosen reference points, either mass or [μg/ml] or air volume [m 3 /ml] related dust quantities in cell culture. Based on the corresponding air volume, LPCi-extracts inhibited IL-4 production to the maximum extend, whereas suppression of IL-4 was comparable based on concentrations. This indicates that not only the disparate PM 0.5 -masses in air cause varying impacts, but also that disparities in PM 0.5 -adsorbed chemicals provoke different effects on immune responses and shifts in the regulatory balance that might have implications for allergy and cancer development

  14. History of radiobiology in Argentina

    Radiobiology is a multidisciplinary science dealing with ionising radiation effects on biological material. The history of Radiobiology begins in Germany and France around 1886. Radiobiology was introduced in Argentina in 1926 at the Institute of Oncology Angel H. Roffo as a biomedical research branch. Later on in 1957 was incorporated at the National Atomic Energy Commission (CNEA) of Argentina as a result of the newly started nuclear activities in Argentina. Prior that time no Radiobiology research existed in Argentina. To fill this need a Project to create new laboratories was elaborated by the CNEA. New laboratories in Radiobiodosimetry, Cellular Radiobiology, Radiopathology, Radiomicrobiology, Genetics and Somatic Effects were created. Human resources on different areas of Radiobiology were formed with the assistance of IAEA. With professional and technical personnel specialized in Radiobiology at the beginning of the 1970 decade, the transference of fundamental and applied research to others laboratories started.

    Argentina's chemical industry association, Camara de la Industria Quimica y Petroquimica (CIQYP; Buenos Aires), has started negotiations with the government aiming to stem industry-wide losses, which reached $236 million during the past 18 months. CIQYP blames the poor performance on worldwide over-supply and falling prices, which have curbed exports, and low tariffs, which have spurred imports. It is calling for higher import tariffs and export incentives. The talks will also focus on a possible bond issue that would support companies willing to restructure and modernize operations. The main factor hindering competitiveness is what CIQYP president Alejandro Achaval calls Argentinean cost, including high energy costs, high provincial and federal taxes, and high financing charges. Since 1988, the industry has cut prices by 30%, formed mergers and joint ventures, closed 11 plants and started five new ones, slashed the workforce by 27%, and engaged in the government's privatization program. Meanwhile, plans to privatize 64% of aromatics producer Petroquimica General Mosconi(PGM) were derailed when potential bidders Diamond Shamrock, Shell, and Perez Companc refused for the second time to make offers on February 2. Jorge Olazabal, planning secretary of the Ministry of Defense, says PGM will be put up for sale again by March

    Much of the published research on evidence-informed health policymaking in low- and middle-income countries has focused on policymakers, overlooking the role of health researchers in the research-to-policy process. Through 20 semi-structured, in-depth qualitative interviews conducted with researchers in Argentina's rural northwest and the capital of Buenos Aires, we explore the perspectives, experiences and attitudes of Argentine health researchers regarding the use and impact of health research in policymaking in Argentina. We find that the researcher, and the researcher's function of generating evidence, is nested within a broader complex system that influences the researcher's interaction with policymaking. This system comprises communities of practice, government departments/civil society organizations, bureaucratic processes and political governance and executive leadership. At the individual level, researcher capacity and determinants of research availability also play a role in contributing to evidence-informed policymaking. In addition, we find a recurrent theme around 'lack of trust' and explore the role of trust within a research system, finding that researchers' distrust towards policymakers and even other researchers are linked inextricably to the sociopolitical history of Argentina, which contributes to shaping researchers' identities in opposition to policymakers. For policymakers, national research councils and funders of national health research systems, this article provides a deeper understanding of researchers' perceptions which can help inform and improve programme design when developing interventions to enhance research utilization and develop equitable and rational health policies. For donors and development agencies interested in health research capacity building and achieving development goals, this research demonstrates a need for investment in building research capacity and training health researchers to interact with the public policy

    Determine the distribution of intestinal parasitosis in children in nine provinces representative of Argentina's mosaic of contrasting environments. Descriptive, observational, cross-sectional study of preschool children (5 years old or under) and school-age children (6-14 years) in the provinces of Buenos Aires (sample taken between 2005 and 2013), Chubut (2010-2013), Corrientes (2012), Entre Ríos (2010-2012), Formosa (2014), La Pampa (2006), Mendoza (2008-2011), Misiones (2005-2008 and 2013), and Salta (2012-2013). Serial samples, fecal samples, and anal swabs were processed using concentration techniques. The results were analyzed by sex, age interval, and province. Frequency of parasitosis (monoparasitosis and multiple parasitoses), wealth of species, and Sørensen similarity coefficient were calculated. Misiones presented the highest frequency of parasitized children and Chubut the lowest (82.0% vs 38.4%; p parasitosis in Formosa (69.2%). The most frequent species in the majority of provinces were Blastocystis sp. and Enterobius vermicularis. Misiones presented the highest frequency of soil-transmitted helminthes (23.3%) and Mendoza the lowest (0.6%); none were found in Chubut, La Pampa, or Salta. Buenos Aires, Formosa, and Misiones presented a similar species composition, as did Chubut and La Pampa. The frequency of parasitosis in Argentina corresponds to the country's complex mosaic of climatic and socioeconomic variability and shows a declining trend from north to south and from east to west.

In a context of limited national historiography related to the study of the empirical practices, we want to probe this problem in two different geographic spaces that formed part, —even today— of a country with strong regional inequalities. We wonder how journalistic representations defined "quackery" as a puzzle whose pieces refer to the State, graduate professionals, the society and the empirical healers themselves. In our reconstruction, we recognize that these discourses were influenced by the editorial course and the ideological affiliation to which the newspapers of two of the most important metropolis of Argentina asserted. Based on a qualitative methodology, we put into an analytical perspective a set of news with the aim to rescue "voices and looks" that contributed to build the empirical practices of heal as a social problem of the public sphere during the years of study.

  20. Air Pollution Episodes Associated with Prescribed Burns

    2017-12-01

    Air pollution events associated with wildfires have been associated with extreme health impacts. Prescribed burns are an important tool to reduce the severity of wildfires. However, if undertaken during unfavourable meteorological conditions, they too have the capacity to trigger extreme air pollution events. The Australian state of New South Wales has increased the annual average area treated by prescribed burn activities by 45%, in order to limit wildfire activity. Prescribed burns need to be undertaken during meteorological conditions that allow the fuel load to burn, while still allowing the burn to remain under control. These conditions are similar to those that inhibit atmospheric dispersion, resulting in a fine balance between managing fire risk and managing ambient air pollution. During prescribed burns, the Sydney air shed can experience elevated particulate matter concentrations, especially fine particulates (PM2.5) that occasionally exceed national air quality standards. Using pollutant and meteorological data from sixteen monitoring stations in Sydney we used generalized additive model and CART analyses to profile the meteorological conditions influencing air quality during planned burns. The insights gained from this study will help improve prescribed burn scheduling in order to reduce the pollution risk to the community, while allowing fire agencies to conduct this important work.

    The mullet Mugil liza is distributed along the Atlantic coast of South America, from Argentina to Venezuela, and it is heavily exploited in Brazil. We assessed patterns of distribution of neutral nuclear genetic variation in 250 samples from the Brazilian states of Rio de Janeiro, São Paulo, Santa Catarina and Rio Grande do Sul (latitudinal range of 23-31°S) and from Buenos Aires Province in Argentina (36°S). Nine microsatellite loci revealed 131 total alleles, 3-23 alleles per locus, He: 0.69 and Ho: 0.67. Significant genetic differentiation was observed between Rio de Janeiro samples (23°S) and those from all other locations, as indicated by FST, hierarchical analyses of genetic structure, Bayesian cluster analyses and assignment tests. The presence of two different demographic clusters better explains the allelic diversity observed in mullets from the southernmost portion of the Atlantic coast of Brazil and from Argentina. This may be taken into account when designing fisheries management plans involving Brazilian, Uruguayan and Argentinean M. liza populations.

    Evidence linking short-term exposure to outdoor air pollution with hemorrhagic stroke is inconsistent. We evaluated the associations between outdoor air pollution and specific types of stroke in Tokyo, Japan, from April 2003 to December 2008. We obtained daily counts of stroke mortality (n = 41,440) and concentrations of nitrogen dioxide as well as particles less than 2.5 μm in diameter. Time-series analysis was employed. Although same-day air pollutants were positively associated with ischemic stroke and intracerebral hemorrhage mortality, both air pollutants were more strongly associated with subarachnoid hemorrhage mortality: rate ratio was 1.041 (95% confidence interval: 1.011-1.072) for each 10 μg/m3 increase in the previous-day particles less than 2.5 μm. This study suggests that short-term exposure to outdoor air pollution increases the risks of hemorrhagic stroke mortality as well as ischemic stroke mortality.

    Full Text Available With few exceptions, the impact of the work of Antonio Gramsci in Argentina is generally associated with the so called “Argentinian gramscians”, many of whom met around the journal Pasado y Presente, headed by José Aricó, without considering Gramsci’s earlier influence. However, it is often forgotten that the first introduction of Gramsci to Argentina was by the hand of Héctor P. Agosti. Agosti influenced many young intellectuals who subsequently congregated around Aricó. Beyond the observations made in this article regarding Agosti’s detractors, the aim here is to contribute to the diffusion, and presentation to the public of the thought of one of the most remarkable intellectuals that have arisen in the Communist Party of Argentina. This article also delves into relatively unexamined connections between the works of Agosti and Grasmci, highlighting the role played by the former in introducing the works of this Italian intellectual into Argentina during that period.

    Full Text Available Examina la relación entre el avance en las tecnologías del transporte y el desarrollo de las expediciones de carácter científico entre fines del siglo XIX y principios del siglo XX en Argentina. Se muestra cómo la expansión a escala nacional de la red de ferrocarriles impactó en el desarrollo de las prácticas en el terreno, ampliando el acceso a sitios distantes de las instituciones científicas ubicadas en Córdoba, Buenos Aires y La Plata, simplificando el movimiento de equipamiento, colecciones y personal. Se toman como ejemplo las expedicións realizadas por Hermann Burmeister (1857-1860, por los científicos de la Academia Nacional de Ciencias de Córdoba y las exploraciones arqueológicas en las provincias del noroeste organizadas por instituciones científicas con sede en Buenos Aires y La Plata.The article explores the relation between the advance of transportation technology and the development of scientific expeditions between the late nineteenth and early twentieth centuries in Argentina. Expansion of the railway network on a national scale impacted the development of the earth sciences by facilitating access to distant places by scientific institutions located in Córdoba, Buenos Aires, and La Plata and also by simplifying the movement of equipment, scientific collections, and personnel. Hermann Burmeister's expedition (1857-60, expeditions by scientists from the Academia Nacional de Ciencias de Córdoba, and archeological digs in the northwestern provinces, organized by scientific institutions headquartered in Buenos Aires and La Plata, serve as examples.

    Full Text Available El estudio de los efectos de la pobreza sobre el desempeño cognitivo durante las primeras fases del desarrollo, ha sido efectuado predominantemente en base a la definición de pobreza según el ingreso y el uso de paradigmas de inteligencia basados en la hipótesis de un factor general de funcionamiento cognitivo. En el presente trabajo se utilizó el concepto de Necesidades Básicas Insatisfechas (NBI como criterio de pobreza y se aplicó un paradigma cognitivo de funcionamiento ejecutivo proveniente de la Neurociencia. El mismo plantea el análisis de componentes de comportamientos inteligentes orientados hacia objetivos y asociados a la activación de circuitos cerebrales que involucran centralmente a la región prefrontal. Se comparó el desempeño ejecutivo de 247 niños escolarizados de 3 a 5 años de edad, provenientes de hogares pobres (NBI y no pobres o con Necesidades Básicas Satisfechas (NBS, y de jardines de infantes del Distrito Escolar 4 de la Ciudad de Buenos Aires (Boca-Barracas y de distritos escolares de Vicente López y San Isidro del Gran Buenos Aires (Argentina. Se administró una batería de pruebas que evalúan componentes de flexibilidad cognitiva, logro de objetivos y control atencional. Los resultados obtenidos muestran perfiles de desempeño diferentes entre ambos grupos. El perfil de desempeño menos eficiente en términos de las variables estudiadas se observó en el grupo de niños proveniente de hogares pobres. Estos resultados constituyen un aporte significativo de un paradigma neurocientífico para la implementación de estrategias de intervención orientadas a estimular el funcionamiento cognitivo de tipo ejecutivo de niños de edad preescolar.

    The aim of this study was to survey and diagnostically characterize the green public spaces in the city of Tandil (Pcia. Bs. As, Argentina). The multivariate analysis (PCA) employed shows the relationships among environmental components (vegetation type and condition, soil, sidewalks and water bodies), infrastructure (benches, playgrounds, lighting) and activities, which reveals relationships bound to green spaces (GS). It was also assessed the degree of association between GS and. population. The results pointed out that, even though the area belonging to squares and small open places, where 83% of the population is concentrated, does not comply with the required percentage stated by the regulations, larger GS (such as parks) influence positively on this estimated index, regarding its function large GS (30%) are bound to a tourist purpose the intermediate ones (52da) to a recreational environmental function, and the smaller ones (20%) are associated with recreational activities or with the urban design. We consider that this research contributes towards the GS characterization, what can be de useful in future green space planning. Besides, it revalues their double function: creative and ecological role in the urban environmental quality

    The growing popularity of cognitive-behavioral therapy (CBT) has helped reshape the mental health scene in the city of Buenos Aires, historically the stronghold of psychoanalysis. In the early 1980s, CBT was infrequently used and sometimes overtly resisted in the field of mental health. Almost 3 decades later, the impact of CBT has increased dramatically in Argentina, not only in independent practice but also in the health system and in everyday life. This article aims to describe the process by which Argentine psychotherapists first adopted this new theoretical framework. (c) 2015 APA, all rights reserved).

    The airborne geophysical surveys developed in Argentina are described. They have got more than 500.000 km 2 acquiring data for U, Th, K and total background activity. Other types of published data are also mentioned (satellite imagery, seismic hazard, climate, soil distributions, etc.). The availability of maps with the abundances of elements analyzed at the country and also at laboratories from Canada is described, as well as data of analysis of several elements at two study areas proposed at the outset of the project. The availability of process rate data and epidemiological data is also explained. Argentina intended fully to participate in the CRP at the outset of the project. Due, however, to external resource constraints imposed on the participating organization (Comision Nacional de Energia Atomica, CNEA), the level of participation had to be significantly reduced. Nonetheless, in the first period of the CRP, Argentina undertook to collate existing geological and geochemical information within the country, and began to define potential areas for site specific natural systems safety indicator studies.

    To verify the association between the air leak objectively measured intraoperatively (IAL) using the ventilator and the air leak duration after pulmonary lobectomy. Prospective analysis on 111 patients submitted to pulmonary lobectomy (33 by video-assisted thoracic surgery). After resection, objective assessment of air leak (in milliliter per minute) was performed before closure of the chest by measuring the difference between a fixed inspired and expired volume, using a tidal volume of 8 ml/kg, a respiratory rate of 10 and a positive-end expiratory pressure of 5 cmH2O. A multivariable analysis was performed for identifying factors associated with duration of postoperative air leak. Average IAL was 158 ml/min (range 0-1500 ml/min). The best cut-off (receiver-operating characteristics analysis) associated with air leak longer than 5 days was 500 ml/min. Nine patients had IAL >500 ml/min (8%). They had a longer duration of postoperative air leak compared with those with a lower IAL (mean values, 10.1 days, SD 8.8 vs 1.5 days, SD 4.9 P leak duration after multivariable regression: left side resection (P = 0.018), upper site resection (P = 0.031) and IAL >500 ml/min (P leak duration was generated: 1.7 + 2.4 × left side + 2.2 × upper site + 8.8 × IAL >500. The air leak measurement using the ventilator parameters after lung resection may assist in estimating the risk of postoperative prolonged air leak. An IAL > 500 ml/min may warrant the use of intraoperative preventative measures, particularly after video-assisted thoracic surgery lobectomy where a submersion test is often unreliable. © 2017 European Society of Cardiology and European Atherosclerosis Association.

    Full Text Available OBJETIVO: Estimar la carga de la enfermedad, su proporción atribuible a los principales factores de riesgo cardiovascular modificables y los costos médicos directos por hospitalización, asociados con las enfermedades coronarias y los accidentes cerebrovasculares en Argentina. MÉTODOS: Se elaboró un modelo analítico a partir de los datos de mortalidad en Argentina en 2005 y la prevalencia de los principales factores de riesgo cardiovascular (hipertensión arterial, hipercolesterolemia, sobrepeso, obesidad, hiperglucemia, tabaquismo actual y pasado, sedentarismo y consumo inadecuado de frutas y verduras. Se estimaron la carga de la enfermedad -años potenciales de vida perdidos (APVP y años de vida saludable (AVISA perdidos- y los costos de hospitalización por las enfermedades cardiovasculares analizadas. RESULTADOS: En 2005 se perdieron en Argentina más de 600 000 AVISA y se contabilizaron casi 400 000 APVP por enfermedades coronarias y accidentes cerebrovasculares; 71,1% de los AVISA perdidos, 73,9% de APVP y 76,0% de los costos asociados son atribuibles a facto-res de riesgo modificables. La hipertensión arterial fue el factor de riesgo de mayor impacto, tanto en hombres como en mujeres: 37,3% del costo total, 37,5% de los APVP y 36,6% de los AVISA perdidos. CONCLUSIONES: La mayor parte de la carga de la enfermedad en Argentina por enfermedades cardiovasculares está relacionada con factores de riesgo modificables -por lo tanto evitables- y podría reducirse mediante intervenciones poblacionales y clínicas basadas en un enfoque de riesgo, que ya han demostrado ser efectivas en función del costo, asequibles y factibles en países como Argentina.OBJETIVE: Estimate the burden of disease, the proportion attributable to the principal modifiable cardiovascular risk factors, and the direct medical cost of hospitalization associated with coronary heart disease and stroke in Argentina.

Tomando el partido de Necochea inserto en la región, esta investigación propone analizar los cambios en el uso del suelo en dicho Partido entre 2003-2011, mediante sensores remotos, y estimar los impactos ambientales asociados con el proceso de agriculturización utilizando indicadores de sustentabilidad. Se realizó una clasificación supervisada sobre imágenes de satélite Landsat 5, se entrevistaron a informantes clave y se relevaron datos de terreno. Históricamente, el Partido ha sido netamente agrícola, y particularmente triguero; sin embargo en 2011 se evidencia que las áreas agrícolas, fundamentalmente sojeras, se incrementaron respecto de 2003 casi un 20% a expensas de las ganaderas. Los indicadores de sustentabilidad estimados para los dos años indican que impactos vinculados al riesgo de contaminación por agroquímicos, riesgo de intervención del hábitat e impactos sobre el ecosistema, fueron significativamente mayores en 2011.

    1991-01-01

    Argentine society in the 1920s experience strong political, cultural, and economic divisions between the littoral regional surrounding Buenos Aires and the interior provinces to the west and north. Economic recession through World War 1 sparked efforts to wean the economy from total dependence upon agricultural production and export, and petroleum deposits in the south and northwest corners of Argentina offered a wider economic base. Regional conflict quickly arose concerning oil production and control over oil revenues. By mounting a popular anti-imperialist campaign against Standard Oil of New Jersey, the primary interior oil producer, dominant political forces in Buenos Aires worked to nationalize all oil deposits to the detriment of interior provincial interests. To maintain the kinds of political control necessary to fend off this threat, interior conservatives reverted to electoral fraud and violence, especially in the major oil-producing province of Salta. This thesis reconstructs and analyzes the process by which political division on the oil issue hardened and gave way to a conservative reaction leading to an authoritarian regime

    Treatment engagement, retention and adherence to care are required for optimal HIV outcomes. Yet, patients may fall below the treatment recommendations for achieving undetectable viral load or not be retained in care. This study examined the most challenging patients in Buenos Aires, Argentina, those non-adherent to HIV care. Men (n = 61) and women (n = 59) prescribed antiretrovirals (ARVs) and non-adherent to treatment in the prior 3 to 6 months were enrolled and assessed regarding adherence, knowledge, motivation and attitudes regarding treatment. Private clinic patients had lower viral load and higher self-reported adherence than public clinic patients. Motivations to be adherent and positive beliefs regarding ARVs were associated with increased adherence in public clinic participants. Increased self-efficacy was associated with increased adherence among participants from both clinics. Results support patient and provider interventions that strengthen the characteristics supporting adherence, engagement and retention in public and private clinic settings. Resumen El compromiso, la retención en el cuidado y adherencia al tratamiento son esenciales para el manejo óptimo del paciente con VIH.

    Full Text Available In August 2007 an outbreak of neurological disease and sudden death in Arabian horses occurred in a farm located in Coronel Rosales County, Buenos Aires Province, Argentina. The animals were on a pasture of native grasses and supplemented ad libitum with corn kernels and wheat bran. Three horses were observed having acute neurologic signs including blindness, four leg ataxia, hyperexcitability, aimless walking and circling, followed by death in two of them. Four other horses were found dead overnight without a history of neurologic signs. The morbidity, mortality and lethality rates were 11.6%, 10% and 85.7%, respectively. Grossly, the brain showed focal areas of hemorrhage, brown-yellow discoloration and softening of the sub-cortical white matter. The microscopic brain lesions consisted of extensive areas of malacia within the white matter of the cerebral hemispheres, brainstem and cerebellum, characterized by rarefaction of the white matter with cavitations filled with proteinaceous edema, multifocal hemorrhages and mild infiltration by neutrophils, and rare eosinophils. Swollen glial cells with abundant eosinophilic cytoplasm, distinct cell borders, intracytoplasmic deeply eosinophilic globules and eccentric, hyperchromatic, occasionally pyknotic nucleus were present throughout the areas of rarefaction hemorrhage, edema and necrosis. The feed supplements contained 12,490µg/kg of fumonisin B1 and 5,251µg/ kg of fumonisin B2. This is the first reported outbreak of ELEM associated with consumption of feed supplements containing high concentrations of fumonisins in Argentina.

    Os planos de gestão costeira integrada (GCI na Argentina são quase inexistentes. No Sul da província de Buenos Aires (Argentina, o planejamento por causa da intensidade da erosão costeira, que afeta especialmente as áreas urbanizadas, é necessário. É fundamental ainda traçar estratégias de GCI que possam ser aplicadas em toda a área de forma sustentável. Neste processo, a participação e o compromisso dos atores sociais são fundamentais. Por esta razão, um guia metodológico foi construído para uma GCI com participação social e aplica-se à localidade de Pehuen Co. Obteve-se como resultado que a erosão costeira e a sazonalidade do turismo são os pilares tanto para a visão científica quanto para a social. Sobre isso, foram delineadas ações e estratégias a curto, médio e longo prazos e indicadores de acompanhamento. Concluiu-se que é necessário o compromisso das autoridades locais, trabalhando em conjunto com as partes interessadas, para o bom funcionamento do GCI.

    Argentina's 31-year-old nuclear research and power program makes it a Third World leader and the preeminent Latin American country. Easily accessible uranium fuels the heavy water reactor, Atucha I, which provides 10% of the country's electric power. Atucha II and III are under construction. Several domestic and international factors combined to make Argentina's program succeed, but achieving fuel-cycle independence and the capacity to divert fissionable material to military uses is a cause for some concern. 60 references

    Full text: Introduction: Stunting is a multifactorial phenomenon with a high prevalence in developing countries. Helicobacter pylori, a bacterium that colonizes the gastric mucosa, has been related to growth impairment due to micronutrient malabsorption. However this hypothesis remains controversial. Objective: The aim of our work was to determine anthropometric indicators in children referred to a Tertiary-level Public Health Care Institution from Buenos Aires, Argentina, for upper gastrointestinal symptoms evaluation. Methods: 525 children (4-16 y) assisting to the Gastroenterology Unit of the Hospital de Niños “Sor María Ludovica”, La Plata, Argentina, were diagnosed for H. pylori infection by the 13C-Urea Breath Test. Weight and height were measured for calculation of anthropometric indicators height for age (HAZ), weight for age (WAZ) and Body Mass Index for age (BMI) using the Anthro Plus 2007 software of the World Health Organization. Statistical analysis was performed by Student’s t Test, Mann-Whitney Test and lineal regression. Results: Prevalence of H. pylori infection was 25.1% (95% CI, 21.5-29.5), with a mean age of the children similar in both groups, 10.1y (95% CI, 9.8-10.3y). Mean HAZ and WAZ were -0.40 (95% CI, -0.57-[-0.22]) and -0.31 (95% CI, -0.51-[-0.11]) in the positive group, and -0.18 (95% CI, -0.28-[-0.09]) and -0.10 (95% CI, -0.21-0.01) in the negative group. HAZ was significantly lower in the positive group (p = 0.04), while no significant differences were found for WAZ (p = 0.07) and BMI for age (p = 0.20) between both groups. However, after adjusting for confounding factors these differences were no longer significant. Stunting was found in 4.5% (95% CI, 2.1-9.6) and 3.3% (95% CI, 1.9-5.6) of the H. pylori positive and negative children respectively, while underweight was observed in 5.3% (95% CI, 2.6-10.5) and 6.7% (95% CI, 4.6-9.6) of the above mentioned groups. Conclusions: Prevalence of stunting and underweight were low in

    The evolution of education in Argentina at the university level is described. The detailed search of the educational offer shows that less than half of the universities (35 out of 92) include chemistry and chemistry related undergraduate programmes in their curriculum. The revision of the position of radiochemistry in these programmes reveals that only seven courses on radiochemistry are currently offered. Radiochemistry is included only in few programmes in chemistry and biochemistry. With respect to the programmes in chemical engineering the situation is worse. This offer is strongly concentrated in Buenos Aires and its surroundings. (author)

    Full Text Available Twenty six isolates of Fusarium graminearum from grains of maize hybrids harvested in ±west Argentina were grown on autoclaved rice grain to assess their ability to produce type B trichothecenes. Chemical analysis indicated that 38% of isolates were nivalenol (NIV producers only, 31% were major NIV producers with high DON(deoxynivalenol/NIV ratios, 8% were major DON producers with minor NIV production, and 23% were DON producers only. Isolates showed a high variability in their toxigenic potential which was not related to fungal biomass. The distribution of the different chemotypes as well as the high and the low trichothecene-producing Fusarium isolates could not be associated to a geographical origin. Our results confirmed for the first time that isolates of Fusarium graminearum from maize of northwest Argentina are able to produce DON and NIV. A substancial contamination with both NIV and DON is likely in maize from northwest Argentina. Their contents should be quantified in regional surveillances for mycotoxin contamination.

    Rickettsia parkeri, a newly recognized tick-borne pathogen of humans in the Americas, is a confirmed cause of spotted fever group rickettsiosis in Argentina. Until recently, almost all cases of R. parkeri rickettsiosis in Argentina have originated from the Paraná River Delta, where entomological surveys have identified populations of R. parkeri-infected Amblyomma triste ticks. In this report, we describe confirmed cases of R. parkeri rickettsiosis from Córdoba and La Rioja provinces, which are located several hundred kilometers inland, and in a more arid ecological region, where A. triste ticks do not occur. Additionally, we identified questing A. tigrinum ticks naturally infected with R. parkeri in Córdoba province. These data provide evidence that another human-biting tick species serves as a potential vector of R. parkeri in Argentina and possibly, other countries of South America. PMID:25349376

    Full Text Available Goats, called “the cow of the poor”, are the livestock species with the most significant population growth worldwide in recent years. Gastrointestinal parasitism constitutes one of the main constraints to its outdoor and extensive breeding in temperate and tropical countries. Despite a Creole goat population of nearly 4 million heads, local reports on parasitological prevalence are scarce, and while Fasciola hepatica infection is spread all over Argentina, the goat is usually neglected as a reservoir and economic losses are not considered. To evaluate gastrointestinal parasitism prevalence and associations between parasite genera and species, with emphasis on fascioliasis, Creole goats from the plateau and Andean regions from western Argentina were investigated by coprological techniques, and associations were statistically assessed. Eighty-five percent (85% of the animals harbored one or more parasite types, while 46% showed mixed infections. Significant positive associations between F. hepatica + Strongyle eggs, Eimeria sp. + Nematodirus sp. and Nematodirus sp. + Trichuris ovis were detected. Further studies are required to define the causality of these associations and their relevance in epidemiology. F. hepatica is rarely considered as goat parasite in the country, but a 33% prevalence poses an interrogation on the role goats play on the transmission and dissemination of this zoonotic trematode.As cabras, nomeadas como “a vaca dos pobres”, são as espécies de gado com o crescimento populacional mais significativo nos últimos anos em todo o mundo. O parasitismo gastrintestinal constitui uma das principais limitações à sua criação extensiva em clima temperado e tropical. Na Argentina, apesar de uma população de caprinos crioulos de cerca de quatro milhões de cabeças, são escassos os relatórios locais de prevalências parasitológicas. Embora a infecção por Fasciola hepatica esteja espalhada em todo o país, as cabras s

    Health inequities are a common problem for all countries and are the result of not only adverse social conditions but also poor public policies. Today chronic diseases represent the most relevant threats and are a current challenge. Parasitic infections, a leading cause of child morbidity affecting low-income populations, can be transmitted because of an unhealthy environment. Notwithstanding, scarce data have been published on the epidemiological profile of intestinal parasitoses in asymptomatic children living in shantytowns. Vulnerable populations settled in slums are growing in Argentina, particularly in Buenos Aires city. Consequently, this work intended to screen healthy carriers of enteric parasites and determine the epidemiologic profile in asymptomatic children residing in one of those communities, to explore risk factors associated with the transmission of parasites, and to initiate a basic health education campaign to promote healthy behavior in the community. Fecal samples (n = 138) were analyzed by conventional parasitological methods and a survey gathered data on symptoms, family composition, and environmental and hygiene-related variables. High prevalence of feco-orally-transmitted parasitoses (83.3%) and polyparasitism were remarkable findings. The main environmental health determinants were those related to excreta disposal and water provision. Health promotion actions were performed through the diffusion of a set of posters with iconic images and brief messages for health education. Results suggest the need for an environmental sanitation policy to complement health promotion actions. It is essential to spread the results of investigations that address inequities and social determinants of health in order to integrate data with local political processes and alert on acceptable actions for developing appropriate interventions.

    Full Text Available Debido a la importancia que la inocuidad de los alimentos entraña para la salud pública, se procuró determinar la calidad microbiológica de los alimentos que consumen los usuarios de los comedores comunitarios del conurbano de Buenos Aires, Argentina. Se trata de un estudio descriptivo, cuyo universo lo conformaron tres municipios con índices medianos y altos de pobreza, de los que se extrajo al azar una muestra de 52 comedores. La información se recolectó desde abril de 1994 hasta abril de 1995 inclusive, por medio de encuestas, observaciones directas y análisis microbiológicos del agua y los alimentos servidos. Los análisis del agua y los alimentos se ajustaron, respectivamente, a las recomendaciones del Código Alimentario Argentino y de la Comisión Internacional de Especificaciones Microbiológicas para Alimentos. Los resultados se interpretaron según los valores para alimentos cocidos acordados por el Grupo de Trabajo de Control de Alimentos. La parte microbiológica del estudio mostró que en 28 (54% de los comedores la comida o el agua era inadecuada y en 11 (21%, ambas eran inadecuadas. Bacillus cereus fue la bacteria patógena que se encontró con mayor frecuencia en los alimentos analizados. Los factores significativamente asociados con condiciones microbiológicas insatisfactorias de las comidas y el agua fueron no desinfectar el agua (P = 0,009, la falta de higiene en el ambiente (P = 0,03, la presencia de roedores e insectos (P = 0,05, el sistema de provisión de materias primas (P = 0,01 y un número de usuarios menor de 100 (P = 0,008.

    A prototype for an integrated system that includes air quality constraints to the procedure that is presently in use to determine the daily economic dispatch of power plants in Argentina is proposed. The recent incorporation of new machines to the installed capacity of the three power plants located in the densely populated metropolitan area of Buenos Aires, the thermal-based future expansion of the power sector and the relatively high nitrogen oxides concentrations that can be associated to electricity generation in the city of Buenos Aires, served to motivate this work. The prototype attempts to generate a dispatch that is compatible with the environment taking into account the present economic dispatch, weather forecast and dispersion models to evaluate ambient air concentrations of nitrogen oxides (NO x ) caused by the combined operation of the thermal power plants. Although the prototype deals exclusively with NO x , since these are the pollutants of primary concern considering the fuel consumption pattern of argentinean power plants, its structure is general enough to take into account other pollutants such as sulfur dioxide and particulate matter.

    Full Text Available Prior research focusing on men who have sex with men (MSM conducted in Buenos Aires, Argentina, used convenience samples that included mainly gay identified men. To increase MSM sample representativeness, we used Respondent Driven Sampling (RDS for the first time in Argentina. Using RDS, under certain specified conditions, the observed estimates for the percentage of the population with a specific trait are asymptotically unbiased. We describe, the diversity of the recruited sample, from the point of view of sexual orientation, and contrast the different subgroups in terms of their HIV sexual risk behavior.500 MSM were recruited using RDS. Behavioral data were collected through face-to-face interviews and Web-based CASI.In contrast with prior studies, RDS generated a very diverse sample of MSM from a sexual identity perspective. Only 24.5% of participants identified as gay; 36.2% identified as bisexual, 21.9% as heterosexual, and 17.4% were grouped as "other." Gay and non-gay identified MSM differed significantly in their sexual behavior, the former having higher numbers of partners, more frequent sexual contacts and less frequency of condom use. One third of the men (gay, 3%; bisexual, 34%, heterosexual, 51%; other, 49% reported having had sex with men, women and transvestites in the two months prior to the interview. This population requires further study and, potentially, HIV prevention strategies tailored to such diversity of partnerships. Our results highlight the potential effectiveness of using RDS to reach non-gay identified MSM. They also present lessons learned in the implementation of RDS to recruit MSM concerning both the importance and limitations of formative work, the need to tailor incentives to circumstances of the less affluent potential participants, the need to prevent masking, and the challenge of assessing network size.

    Full Text Available Habitat use of rodents is associated to environmental variables, species requirements and biological interactions. The aim of this study was to analyse the macro and microhabitat use and spatial variation in the abundance of small wild rodents that inhabit Otamendi Natural Reserve, Argentina. We studied the rodent communities in 6 habitats: riparian forest, Celtis tala forest, lowland grassland, salt marsh and 2 highland grasslands. We captured a total of 153 individual of Scapteromys aquaticus, Akodon azarae, Oxymycterus rufus, Oligoryzomys flavescens, Deltamys kempi and O. nigripes, with a trapping effort of 3636 trap-nights. The species richness is maintained by the presence of different habitats that satisfy specific requirements from specialist and generalist species, using differentially the reserve and forming communities of different specific composition in each habitat. A differential macrohabitat use was observed by all species, and a certain level of selectivity at microhabitat scale was observed in individuals of 2 species. This study shows that the diversity of environments in the Otamendi Natural Reserve, which allows the maintenance of many wild species of small rodents; confirming the high ecological and conservational value of the reserves inside an urban region.El uso del habitat de los roedores está asociado a variables ambientales, requerimientos específicos e interacciones biológicas.

    Indoor air pollution is associated with cardiovascular effects, however, little is known about the effects of improving indoor air quality on cardiovascular health. The aim of this study was to explore whether improving indoor air quality through air conditioning can improve cardiovascular health in human subjects. We recruited a panel of 300 healthy subjects from Taipei, aged 20 and over, to participate in six home visits each, to measure a variety of cardiovascular endpoints, including high sensitivity-C-reactive protein (hs-CRP), 8-hydroxy-2'-deoxyguanosine (8-OHdG), fibrinogen in plasma and heart rate variability (HRV). Indoor particles and total volatile organic compounds (VOCs) were measured simultaneously at the participant's home during each visit. Three exposure conditions were investigated in this study: participants were requested to keep their windows open during the first two visits, close their windows during the next two visits, and close the windows and turn on their air conditioners during the last two visits. We used linear mixed-effects models to associate the cardiovascular endpoints with individual indoor air pollutants. The results showed that increases in hs-CRP, 8-OHdG and fibrinogen, and decreases in HRV indices were associated with increased levels of indoor particles and total VOCs in single-pollutant and two-pollutant models. The effects of indoor particles and total VOCs on cardiovascular endpoints were greatest during visits with the windows open. During visits with the air conditioners turned on, no significant changes in cardiovascular endpoints were observed. In conclusion, indoor air pollution is associated with inflammation, oxidative stress, blood coagulation and autonomic dysfunction. Reductions in indoor air pollution and subsequent improvements in cardiovascular health can be achieved by closing windows and turning on air conditioners at home. Copyright © 2013 Elsevier B.V.

    Background/aim Argentina has one of the highest cigarette smoking rates among both men and women in the Americas and no legislated restrictions on tobacco industry advertising. The tobacco industry has traditionally expanded markets by targeting adolescents and young adults. The objective of this study was to determine whether and how the tobacco industry promotes cigarettes to adolescents in Argentina. Methods We conducted a systematic search of tobacco industry documents available through the internet dated between 1995 and 2004 using standard search terms to identify marketing strategies in Argentina. A selected review of the four leading newspapers and nine magazines with reported high readership among adolescents was completed. The selected print media were searched for tobacco images and these were classified as advertisements if associated with a commercial product or as a story if not. Results The tobacco industry used market segmentation as a strategy to target Argentinean consumers. British American Tobacco (BAT) undertook a young adult psychographic study and classified them as “progressives”, “Jurassics” or “conservatives” and “crudos” or “spoiled brats”. BAT marketed Lucky Strike to the “progressives” using Hollywood movies as a vehicle. The tobacco industry also targeted their national brands to the conservatives and linked these brands with “nationalistic values” in advertising campaigns. Philip Morris promoted Marlboro by sponsoring activities directed at young people and they launched the 10 cigarettes packet as a starter vehicle. Conclusions The tobacco industry used psychographic segmentation of the population and developed advertising strategies focused on youth. Tobacco control researchers and advocates must be able to address these strategies in counter-marketing interventions. PMID:18299308

    In Argentina, the epidemiological and molecular characteristics of Chlamydia psittaci infections are still not sufficiently known. A total of 846 respiratory and 10 ocular samples from patients with suspected human psittacosis were tested for C. psittaci from January 2010 to March 2015. Four samples of birds related to these patients were also studied. Forty-eight samples were positive for C. psittaci by a nested PCR. The molecular characterization of twelve C. psittaci PCR-positive samples received in the National Reference Laboratory INEI-ANLIS "Dr. Carlos G. Malbrán", Buenos Aires, Argentina was performed. Eight positive samples from humans and four from birds were genotyped by ompA gene sequencing. C. psittaci genotype A was found in all human samples and in the related birds. This report contributes to our increasing knowledge of the epidemiological and molecular characteristics of C. psittaci to conduct effective surveillance of its zoonotic infections.

    The aim of the study was to assessed the impact of short-term exposure to air pollution on ischemic stroke subtype, while focusing on stroke caused via cardioembolism. From a nationwide, multicenter, prospective, stroke registry database, 13 535 patients with acute ischemic stroke hospitalized to 12 participating centers were enrolled in this study. Data on the hourly concentrations of particulate matter <10 μm, nitrogen dioxide (NO 2 ), sulfur dioxide (SO 2 ), ozone (O 3 ), and carbon monoxide (CO) were collected from 181 nationwide air pollution surveillance stations. The average values of these air pollutants over the 7 days before stroke onset from nearest air quality monitoring station in each patient were used to determine association with stroke subtype. The primary outcome was stroke subtype, including large artery atherosclerosis, small-vessel occlusion, cardioembolism, and stroke of other or undetermined cause. Particulate matter <10 μm and SO 2 concentrations were independently associated with an increased risk of cardioembolic stroke, as compared with large artery atherosclerosis and noncardioembolic stroke. In stratified analyses, the proportion of cases of cardioembolic stroke was positively correlated with the particulate matter <10 μm, NO 2 , and SO 2 quintiles. Moreover, seasonal and geographic factors were related to an increased proportion of cardioembolic stroke, which may be attributed to the high levels of air pollution. Our findings suggest that the short-term exposure to air pollutants is associated with cardioembolic stroke, and greater care should be taken for those susceptible to cerebral embolism during peak pollution periods. Public and environmental health policies to reduce air pollution could help slow down global increasing trends of cardioembolic stroke. © 2016 American Heart Association, Inc.

    Full Text Available The aim of this study was to assemble data on the summer feeding ecology of the Great Pampa-finch, Embernagra platensis at the Laguna de Guaminí, Buenos Aires, Argentina, and to explore the differences related to the dietary patterns for each sex between winter and summer when possible. The stomach contents of 43 birds were analyzed. The animal fraction was composed of Hymenoptera (45.1%, Coleoptera (32.4%, Lepidoptera (6.0%, Araneae (5% and Orthoptera (3.2%. The application of the index of relative importance (IRI resulted in 1490.4 for Coleoptera, 428.5 for Hymenoptera and 162.5 for Lepidoptera caterpillars. The vegetal fraction consisted of Triticum aestivum (26.9%, Cyperaceous (25%, Poaceae (Gramineae (19.3% and Panicum sp. (11.2%. The IRI values were 893.8 for Triticum aestivum, 174.5 for Gramineae, 126.5 for Panicum sp. and 112.8 for Scirpus sp. The food niche width was 0.33 for both sexes; the diversity index resulted in 1.06 for females and 1.33 for males and specific diversity ranged from 1.87 to 2.84. A canonical component analysis (CCA was performed on environmental and morphometric variables, and a Monte Carlo test confirmed the canonical correlations. A t-test showed that some birds harmonized with a logarithmic model and some with a geometric curve. During the summer, Embernagra platensis ingests Hymenoptera and Coleoptera more often than seeds, suggesting that two biological mechanisms could be taking place in this bird.O objetivo deste estudo foi reunir dados referentes à ecologia alimentar do Sabiá-do-banhado, Embernagra platensis, na laguna de Guaminí, Buenos Aires, Argentina, e explorar as diferenças relacionadas aos padrões dietéticos para cada sexo entre inverno e verão, quando possível.

    Full Text Available The coastal spaces are fragile and complex areas that receive strong pressure because of the many uses and activities that are developed in them. The tourism of sun and beaches is one of the main economic practices present in these spaces that value the physical-natural conditions and their environmental variables. Of all of them, the sea surface temperature (SST has been the least studied variable, especially associated to tourist destinations. The coastal zone of the province of Buenos Aires, Argentina, concentrates numerous tourist centers like the Partido de la Costa, Pinamar and Villa Gesell that attract in the summer time, a great flow of population. The objective of the present paper was to perform a descriptive and comparative analysis of SST in these parties through the use of monthly satellite images obtained by the Aqua-MODIS satellite-sensor during the period 2003-2013. The results showed a spatial and seasonal behavior of the SST differentiated for the entire study area. The SST for the warm period (January-March ranged between 21.5 - 24.5°C and for the cold (July-September between 9.4 - 11.5°C. This difference was lower in the cold period, allowing distinguishing 3 thermal zones with variations smaller than 0.5°C between them: Costa Norte, Costa Centro- Costa Sur, and Pinamar-Villa Gesell. The warm period presented more intense spatial thermal variations between the studied tourist destinations. Four thermal zones with 0.5°C differences were identified: Costa Norte, Costa Centro, Costa Sur, and Pinamar-Villa Gesell.

    Ten Leptospira spp. strains were isolated from water samples from Nievas stream, Olavarría, Buenos Aires province (Argentina). The isolates showed the typical motility and morphology of the genus Leptospira under dark field microscopy, developing in liquid EMJH medium after eight days of incubation at 13°C and 30°C. All isolates were negative by the Multiple Locus Variable Number Tandem Repeat Analysis (MLVA). Molecular identification by 16S rRNA gene sequencing identified all isolates as nonpathogenic leptospires. Four isolates showed a genetic profile identical to that of the reference strain Leptospira biflexa serovar Patoc, and six isolates revealed sequence similarities within the 97-98% range, closely related to Leptospira yanagawae and Leptospira meyeri, respectively. Strains ScialfaASA42, ScialfaASA45, ScialfaASA44, ScialfaASA47, ScialfaASA49, ScialfaASA50 and ScialfaASA51 possibly represent a novel species of the genus Leptospira.

    In May 2012, Argentina passed its "Gender Identity" Law, which aimed to address the legal invisibility, discrimination and marginalization that transgender individuals have historically faced. The aim of this study was to explore factors associated with engagement with the Gender Identity Law among transwomen living in Argentina. Data were derived from a 2013 nationwide, cross-sectional study involving transwomen in Argentina. Using multivariate logistic regression, we assessed the prevalence and factors associated with acquiring a gender-congruent identity card within the first 18 months of enactment of the Gender Identity Law. Among 452 transwomen, 260 (57.5%) reported that they had obtained a new gender-congruent identity card. In multivariate analysis, factors positively associated with acquiring a new ID were: previously experiencing discrimination by healthcare workers (adjusted odd ratio [aOR] = 2.01, 95% CI: 1.27-3.20); having engaged in transition procedures (aOR = 3.06, 95% CI: 1.58-5.93); and having a job other than sex work (aOR = 1.81, 95% CI: 1.06-3.10). Foreign born transwomen were less likely to have obtained a new ID (aOR = 0.14, 95% CI: 0.06-0.33). More than half of transwomen in our sample acquired a new gender-congruent ID within the first 18 months of enactment of the Gender Identity Law. However, access to and uptake of this right has been heterogeneous. In particular, our findings suggest that the most empowered transwomen may have been among the first to take advantage of this right. Although educational level, housing conditions, HIV status and sex work were not associated with the outcome, foreign-born status was a strong negative correlate of new ID acquisition. Therefore, additional efforts should be made in order to ensure that benefits of this founding policy reach all transwomen in Argentina.

    Full Text Available In May 2012, Argentina passed its "Gender Identity" Law, which aimed to address the legal invisibility, discrimination and marginalization that transgender individuals have historically faced. The aim of this study was to explore factors associated with engagement with the Gender Identity Law among transwomen living in Argentina.Data were derived from a 2013 nationwide, cross-sectional study involving transwomen in Argentina. Using multivariate logistic regression, we assessed the prevalence and factors associated with acquiring a gender-congruent identity card within the first 18 months of enactment of the Gender Identity Law.Among 452 transwomen, 260 (57.5% reported that they had obtained a new gender-congruent identity card.

    Argentina's Congress has voted to fully privatize state petroleum company Yacimientos Petroliferos Fiscales (YPF), a move the government expects to net at least $8 billion. Despite some political opposition, the vote was 119-10 in favor, with one abstention and opposition party members refusing to participate in the vote. Argentina's President Carlos Menem had threatened to authorize YPF privatization by decree if there was no quorum for a vote. YPF is responsible for 40% of Argentina's oil production. The country h as been self-sufficient in crude since 1982. Current production is 563,472 b/d, and proved reserves of oil and gas are valued at $7 billion

    The concentration of radon gas in dwellings of several cities of Argentina was measured. For this purpose, different kind of detectors were used such as passive solid state nuclear track detectors, electrets and detectors which use activated charcoal. Since 1983, a total of 1630 dwellings were analysed. The cases monitored were dwellings where the main construction materials are reinforced concrete and brick. The average values found in each city are below 50 Bq/m 3 . The values above 200-Bqm 3 are very few, and none of them is above 300 Bq/m 3 . The average value of radon gas in air dwellings in our country is 33 Bq/m 3 , with a geometric mean of 23 Bq/m 3 , corresponding to an annual effective dose of 0.83 mSv. (author) [es

Revista de la nueva generación (1923-1927 to show the ambivalent reception of the movement in the River Plate. The Argentinean reaction ranged from the celebratory tribute to the rejection, differently from the Spanish Ultraism, that admired the futurist motifs. We will also mention the Argentine painters who accused the influence of the Italian movement as well as another phenomena that allows us to speak of a “warm local adaptation” of the Futurism in the pages of Rovente (1924, a magazine published in Buenos Aires by Pietro Illari.

    Full Text Available El aluvión inmigratorio italiano en Argentina marcó en el campo literario tensiones propias del mestizaje cultural que impactan en las sociedades receptoras. Es particularmente significativo, en esta ocasión, analizar dos casos de la literatura argentina de la segunda mitad del siglo XX. Las cartas de Manuel Puig (Querida Familia: Tomo 1, Cartas Europeas, Entropía, Bs.

    Full Text Available The study analyzes the migratory waves from Friuli which, from the 1870s up to the post-World War II years, extensively moved towards Argentina, settling in the areas around the cities of Santa Fe, Cordoba, Entre Ríos, Chaco and Buenos Aires, but reaching also regions as far away as Patagonia. The accurate and well diffused net of the Fogolār Furlan, besides its function as friendly society, also provides to the promulgation of ancient traditions and mores among the new generations, transmitting on to them the cultural, linguistic and ethnic memory of the motherland. Epistles, tales, novels and poems form a paideia which is thus constantly being enlivened, eveng among those who assumed Argentinian nationality or were born in the country. Of utmost interest is, therefore, the resulting literary corpus, representing as it does a renewed search for identity in the form of a dialogue with the world, extending itself well beyond the contingency of boundaries and transmitting the universal essence of logos.

    1997-01-01

    Argentina has been conducting nuclear activities for more than forty years, and as early as in 1956 established a Regulatory Authority. Procedures for compliance monitoring and enforcement have been in use in the regulatory control of radioactive sources, and regulatory standards and regulations had been set in Argentina, before the accident in Goiania. The conclusions drawn from that accident encouraged in Argentina the improvement of some regulatory procedures and helped to enhance the quality of the regulatory process. Therefore, the effectiveness of the control of spent radioactive sources has gradually increased, and enforcement actions to prevent radioactive sources ending up in the public domain improved. Some lessons learned in Argentina from the accident in Goiania and the main characteristics of an effective enforcement program helpful to prevent radiological accidents in industrial, medical, research and teaching uses of radioactive sources are presented.

Así, en el Hospital Posadas convivieron, simultáneamente, las prácticas relativas al cuidado y restauración de la salud y la perpetración de torturas y asesinatos. En este trabajo se analizarán los recuerdos y olvidos de estos hechos entre diversos vecinos que habitaban, en tiempos de la dictadura, en las inmediaciones del Hospital Posadas. Específicamente, se indagará qué experiencias tuvieron con la violencia de Estado, en particular con el sistema de desaparición de personas, y cómo ellas han quedado inscriptas en sus memorias personales. Por último, se analizarán la información que circulaba y los grados de conocimiento que poseían estos vecinos sobre los atributos, naturaleza y responsables de las desapariciones en el hospital mientras éstas se perpetraban.

    Full Text Available La equidad en educación es socialmente deseable debido a la relevancia de la formación en el desarrollo de las personas. Por ello, resulta interesante estudiar si la asignación del gasto destinado a educación tiene en cuenta este aspecto. Dado que el concepto de equidad no es un unívoco, es necesario definir una postura; en el trabajo se asume que existe equidad educativa si hay igualdad en los resultados educativos. Así, el objetivo de éste es analizar si la distribución del gasto educativo entre los distritos de la provincia de Buenos Aires, Argentina, es equitativa. Se planteó la hipótesis de que no lo es. Para contrastarla, se utilizó el coeficiente de GINI y una regresión de Mínimos Cuadrados Ordinarios (MCO. Se halló que la distribución de los fondos se vincula en forma directa con el grado de analfabetismo de los distritos, pero al mismo tiempo se encontró evidencia de que es independiente de la pobreza, de la tasa de abandono escolar, del porcentaje de matrícula en los niveles iniciales y de la proporción de establecimientos clasificados como desfavorables. Entonces, se concluye que la distribución de los fondos de gastos educativos no se rige, o lo hace muy débilmente, por el principio de equidad considerado en el trabajo. Es decir, que la evidencia empírica verifica la hipótesis propuesta.

En este contexto, han surgido numerosas estrategias de recuperación o generación de nuevas fuentes de trabajo, algunas de las cuales se las identifica como parte de un amplio y heterogéneo conjunto de experiencias de economía social. En particular, en este trabajo nos centraremos en el análisis de 611 emprendimientos Asociativos mercantiles y 50 empresas recuperadas de Argentina a fin de caracterizar estas experiencias y mostrar su desempeño en relación a la recuperación y creación de fuentes de trabajo. Para ello nos basaremos en los datos construidos en el estudio “Emprendimientos socioeconómicos asociativos: su vulnerabilidad y sostenibilidad” (ICO-UNGS, 2006.Towards the end of the twentieth century, Argentina faced a social, political and economic crisis of monumental dimensions. This emergency translated into increased poverty and inequality, and a structural crisis in the job market. In this context, a number of strategies arose, aimed at recuperating some of the loss, and generating new possibilities in the job market. Some of these strategies were identified as part of a wide-ranging and heterogeneous series of experiments in social economics. This work will focus on an analysis of 611 associate market initiatives and 50 recuperated companies in Argentina, for the purpose of characterizing these experiences and showing their drive to create and regenerate sources of employment. To achieve this, we will take as our starting point the data collected for the Study "Socio-Economic Associative Initiatives: Vulnerability and Sustainability" (ICO-UNGS, 2006.

  1. Higher fuel prices are associated with lower air pollution levels.

    2014-05-01

    Air pollution is a persistent problem in urban areas, and traffic emissions are a major cause of poor air quality. Policies to curb pollution levels often involve raising the price of using private vehicles, for example, congestion charges. We were interested in whether higher fuel prices were associated with decreased air pollution levels. We examined an association between diesel and petrol prices and four traffic-related pollutants in Brisbane from 2010 to 2013. We used a regression model and examined pollution levels up to 16 days after the price change. Higher diesel prices were associated with statistically significant short-term reductions in carbon monoxide and nitrogen oxides. Changes in petrol prices had no impact on air pollution. Raising diesel taxes in Australia could be justified as a public health measure. As raising taxes is politically unpopular, an alternative political approach would be to remove schemes that put a downward pressure on fuel prices, such as industry subsidies and shopping vouchers that give fuel discounts.

    HTLV-1 Cosmopolitan subtype Transcontinental subgroup A has been described among aboriginal communities from the northwest endemic area of Argentina. Moreover, Transcontinental subgroup A and the Japanese subgroup B were reported among blood donors from the nonendemic central region of the country. We carried out the first HTLV-1 phylogenetic study in individuals residing in Buenos Aires capital city. Phylogenetic analysis performed on the LTR region showed that all 44 new strains clustered within the Cosmopolitan subtype, with 42 (95.4%) belonging to Transcontinental subgroup A. Of them, 20 (45.5%) strains grouped in the large Latin American cluster and 4 (9.1%) in the small Latin American cluster. The majority of them belonged to individuals of nonblack origin, grouped with Amerindian strains. Three (6.8%) were closely related to South African references and two monophyletic clusters including only HIV/HTLV-1 coinfected individuals were observed. Interestingly, two (4.5%) new sequences (divergent strains) branched off from all five known Cosmopolitan subgroups in a well-supported clade. In summary, these findings show that HTLV-1 Cosmopolitan subtype Transcontinental subgroup A is infecting residents of Buenos Aires, a nonendemic area of Argentina, and confirm the introduction of divergent strains in the country.

    In 1879 Benjamin Apthorp Gould published in Buenos Aires, Argentina, the Uranometria Argentina catalog of 7756 stars south of declination +10 degrees. This included all those stars he considered magnitude 7 or brighter and some fainter stars which are close companions to brighter stars or to each other and have combined magnitude 7 or brighter. Star positions are in 1875 coordinates, and constellation boundaries also in 1875 coordinates were defined within the aforementioned declination range. With only a few small changes these were incorporated into the boundaries adopted by the IAU in 1930 and subsequently universally accepted. In terms of accurate photoelectric magnitude measurements the Uranometria Argentina is nearly complete to magnitude 6.5 in its declination range. In each constellation the individual stars considered to be magnitude 7 and brighter were numbered in sequence of increasing right ascension in 1875 coordinates, except that in a few cases this sequence was somewhat adjusted so that stars close together could be listed on adjacent lines of text. The numbering system is analogous to that in the Flamsteed Catalogus Brittanicus and now widely used. Star numbers from the Uranometria Argentina rarely appear in the 21st century despite the potential utility of their use. They were included in the American Ephemeris and Nautical Almanac until 1978, and in the FK5 catalog until 1999, always with the letter G following the number in the Uranometria Argentina catalog. This serves to distinguish Flamsteed numbers with no following letters from Gould numbers, and is utilized in this presentation and recommended for general use. The file catalog.dat includes every star in the original Uranometria Argentina. In the original the constellations were presented in sequence of increasing distance from the south pole and numbered accordingly. For the convenience of 21st century astronomers the constellations are presented here by alphabetical sequence in

The English version of the 1996 edition was published in December 1996 and the Spanish one in September 1997. Such edition was the culmination of a difficult consensus and harmonisation reached after an analysis process of the-years cycle between the IAEA Member Sates and related international organisations (United Nations, International Civil Aviation Organisation, International Air Transport Association, International Federation of Air Lines Pilots Associations, International Maritime Organisation) as well as regional organisations (Economic Commission for Europe, Commission of the European Communities). Both editions of the Regulations include a set of design, operational and administrative requirements that substantially do not differ as for their safety basic philosophy. However, the 1996 edition introduces numerous modifications of different magnitude, which will derive in technological, economic and operative consequences. Of such modifications the paper only analysed the relevant ones which update the state of art in the subject and allow the Regulations continue maintaining an acceptable level of control of the radiation, criticality and thermal hazards to persons, property and the environment during the transport of radioactive material. In addition, the paper briefly describes the possible impact that the main modifications induced in the 1996 edition of the Regulations should have, depending on the type of user considered either in Argentina or in other Latin America countries. However, it is desirable that the personal of competent authorities of each country involved in transport

    Full Text Available Human astroviruses have been increasingly identified as important agents of diarrheal disease in children. However, the disease burden of astrovirus infection is still incompletely assessed. This paper reports results on the epidemiological and clinical characteristics of astrovirus-associated diarrhea, as well as the impact of astrovirus infection on the ambulatory setting at a Public Hospital in Córdoba city, Argentina. From February 2001 through January 2002, 97 randomly selected outpatient visits for diarrhea among children 0.05. According to our estimation about one out of seventy-four children in this cohort would be assisted annually for an astroviral-diarrheal episode in the Public Hospital and one out of eight diarrheal cases could be attributed to astrovirus infection. Astrovirus is a common symptomatic infection in pediatric outpatient visits in the public hospital in the study area, contributing 12.37% of the overall morbidity from diarrhea.

    While pneumatosis cystoides intestinalis (PCI) is a rare disease entity associated with a wide variety of gastrointestinal and non-gastrointestinal disorders, PCI associated with massive intra- and retroperitoneal free air is extremely uncommon, and is difficult to diagnose differentially from perforated peritonitis. We present two cases of PCI associated with massive peritoneal free air and/or retroperitoneal air that mimicked perforated peritonitis. These cases highlight the clinical importance of PCI that mimics perforated peritonitis, which requires emergency surgery. Preoperative imaging modalities and diagnostic laparoscopy are useful to make an accurate diagnosis.

    The Autoridad Regulataria Nuclear (ARN) and the United States Department of Energy (DOE) are cooperating on the development of a Remote Monitoring System for nuclear nonproliferation efforts. A Remote Monitoring System for spent fuel transfer will be installed at the Argentina Nuclear Power Station in Embalse, Argentina. The system has been designed by Sandia National Laboratories (SNL), with Los Alamos National Laboratory (LANL) and Oak Ridge National Laboratory (ORNL) providing gamma and neutron sensors. This project will test and evaluate the fundamental design and implementation of the Remote Monitoring System in its application to regional and international safeguards efficiency. This paper provides a description of the monitoring system and its functions. The Remote Monitoring System consists of gamma and neutron radiation sensors, RF systems, and video systems integrated into a coherent functioning whole. All sensor data communicate over an Echelon LonWorks Network to a single data logger. The Neumann DCM 14 video module is integrated into the Remote Monitoring System. All sensor and image data are stored on a Data Acquisition System (DAS) and archived and reviewed on a Data and Image Review Station (DIRS). Conventional phone lines are used as the telecommunications link to transmit on-site collected data and images to remote locations. The data and images are authenticated before transmission. Data review stations will be installed at ARN in Buenos Aires, Argentina, ABACC in Rio De Janeiro, IAEA Headquarters in Vienna, and Sandia National Laboratories in Albuquerque, New Mexico. 2 refs., 2 figs

    Full Text Available Este artículo trata los movimientos sociales autónomos que surgieron después de la crisis económica y la posterior rebelión popular en Argentina en diciembre de 2001. Los movimientos autónomos en la Argentina, como tantos movimientos en el mundo de hoy, son movimientos basados en la creación de nuevas relaciones sociales y comunidades ahora, al mismo tiempo que proyectan nuevas sociedadesy las relaciones en y para el futuro. Son movimientos con una concepción diferente del tiempo y el espacio. Son movimientos queentienden lo individual y lo colectivo como vinculados entre sí. Hay mucho en común entre la experiencia en la Argentina y las prácticas eideas anarquistas. Eso no significa que los que están creando nuevas relaciones y comunidades en la Argentina sean anarquistas. Lo que este artículo intenta hacer es basarse en las experiencias de los movimientos sociales argentinos para iniciar una reflexión sobre lasprácticas e ideas que los anarquistas pueden prestar a los distintos movimientos y comunidades autónomas; y, a su vez, sobre lo que los movimientos autónomos en la Argentina puede dar a las ideas y prácticas anarquistas.

  16. The association of air temperature with cardiac arrhythmias

    2017-11-01

    The body response to meteorological influences may activate pathophysiological mechanisms facilitating the occurrence of cardiac arrhythmias in susceptible patients. Putative underlying mechanisms include changes in systemic vascular resistance and blood pressure, as well as a network of proinflammatory and procoagulant processes. Such a chain reaction probably occurs within the time window of several hours, so use of daily average values of meteorological elements do not seem appropriate for investigation in this area. In addition, overall synoptic situation, and season-specific combinations of meteorological elements and air pollutant levels probably cause the overall effect rather than a single atmospheric element. Particularly strong interrelations have been described among wind speed, air pressure and temperature, relative air humidity, and suspended particulate matter. This may be the main reason why studies examining the association between temperature and ventricular arrhythmias have found linear positive, negative, J-shaped or no association. Further understanding of the pathophysiological adaptation to atmospheric environment may help in providing recommendations for protective measures during "bad" weather conditions in patients with cardiac arrhythmias.

    2004-11-01

    At the suggestion of a social worker who witnessed abusive post-abortion care at a public hospital in Rosario, Argentina, two human rights NGOs collaborated to investigate women's experiences seeking treatment for abortion complications at area public hospitals. During the year-long enquiry, more than 300 women took part. Role play was successfully used to surmount women's initial reluctance to reveal pervasive discriminatory and humiliating mistreatment. Thirty-one women later gave personal testimonies about their experiences, which were contained in the report of the research and later dramatised in a public meeting and video. The report, Con Todo al Aire (With Everything Exposed), was disseminated widely, including to the media, and a formal complaint was made to the local Ombudsman, who called for high-level action to resolve the problems. Initial denial by some health professionals that there was a serious problem was replaced by critical self-assessment within the provincial government, hospitals and medical and nursing schools, who made commitments to reform hospital practices and the medical school curriculum. Women participants also gained an understanding of their right to appropriate and humane health care. The findings from Rosario are not isolated. They are now being shored with activists and researchers in other provinces of Argentina and other countries.

    1997-12-31

    Argentina has been conducting nuclear activities for more than forty years, and as early as in 1956 established a Regulatory Authority. Procedures for compliance monitoring and enforcement have been in use in the regulatory control of radioactive sources, and regulatory standards and regulations had been set in Argentina, before the accident in Goiania. The conclusions drawn from that accident encouraged in Argentina the improvement of some regulatory procedures and helped to enhance the quality of the regulatory process. Therefore, the effectiveness of the control of spent radioactive sources has gradually increased, and enforcement actions to prevent radioactive sources ending up in the public domain improved. Some lessons learned in Argentina from the accident in Goiania and the main characteristics of an effective enforcement program helpful to prevent radiological accidents in industrial, medical, research and teaching uses of radioactive sources are presented.

    Full Text Available We describe the characterization of the viral genotype involved in the first case of hantavirus pulmonary syndrome reported in Tucumán, a Northwestern province of Argentina. A 23-year-old woman, with no record of travel history and previously diagnosed with an antiphospholipid syndrome, died after 11 days of severe cardiopulmonary insufficiency. Among the four endemic regions of hantavirus pulmonary syndrome in Argentina, the Northwest Region has the highest incidence, exceeding 50% of all reported cases in the country. Until now, only Salta and Jujuy (2 out of the 6 provinces composing the Northwest Region, reported cases of hantavirus pulmonary syndrome, all of which occurred in the Yungas Forest area. Remarkably, the viral genotype characterized in this case showed higher nucleotide identity with the Andes-BsAs genotype most prevalent in Buenos Aires province, located 1400 km apart from Tucumán, than with any of the commonly found genotypes in the Northwest Region. The Andes-BsAs genotype has been associated with 30% lethality and interhuman transmission in Buenos Aires province. Interhuman transmission cannot be ruled out in the present case

    Full Text Available Cemeteries are ideal urban areas to study the importance of different types of containers as breeding sites of Aedes aegypti (L.. In the present study, the suitability of plastic, glass, ceramic and metal containers was evaluated in four patches within a cemetery of Buenos Aires City, Argentina. Between October 1998 and May 2000, we found 215 breeding sites of Ae. aegypti out of 13,022 water-filled containers examined. In two patches containing microenvironments sheltered from the sun, the use of the different types of containers was proportional to the offer (correlation coefficient = 0.99, P < 0.05 in both cases. In the remaining patches, plastic and metal containers were the most and less frequent breeding sites, respectively (P < 0.001 in both cases. The number of immatures per breeding site (median = 4.5 did not show significant differences among the four types of containers examined (H3, 215 = 1.216, P = 0.749. Differences found in patches from a same cemetery suggest that different microenvironmental conditions affect the suitability of each type of container for Ae. aegypti breeding. Plastic containers appeared as key breeding sites that should be removed to reduce the Ae. aegypti population in the study area.

    Cohorts based on administrative data have size advantages over individual cohorts in investigating air pollution risks, but often lack in-depth information on individual risk factors related to lifestyle. If there is a correlation between lifestyle and air pollution, omitted lifestyle variables may result in biased air pollution risk estimates. Correlations between lifestyle and air pollution can be induced by socio-economic status affecting both lifestyle and air pollution exposure. Our overall aim was to assess potential confounding by missing lifestyle factors on air pollution mortality risk estimates. The first aim was to assess associations between long-term exposure to several air pollutants and lifestyle factors. The second aim was to assess whether these associations were sensitive to adjustment for individual and area-level socioeconomic status (SES), and whether they differed between subgroups of the population. Using the obtained air pollution-lifestyle associations and indirect adjustment methods, our third aim was to investigate the potential bias due to missing lifestyle information on air pollution mortality risk estimates in administrative cohorts. We used a recent Dutch national health survey of 387,195 adults to investigate the associations of PM 10 , PM 2.5 , PM 2.5-10 , PM 2.5 absorbance, OP DTT, OP ESR and NO 2 annual average concentrations at the residential address from land use regression models with individual smoking habits, alcohol consumption, physical activity and body mass index. We assessed the associations with and without adjustment for neighborhood and individual SES characteristics typically available in administrative data cohorts. We illustrated the effect of including lifestyle information on the air pollution mortality risk estimates in administrative cohort studies using a published indirect adjustment method. Current smoking and alcohol consumption were generally positively associated with air pollution. Physical activity

    2013-01-01

    Argentina is one of the world's largest biodiesel producers and the largest exporter, using soybeans as feedstock. Using a computable general equilibrium model that explicitly represents the biofuel industry, this study carries out several simulations on two sets of issues: (i) international markets for biofuel and feedstock, such as an increase in prices of soybean, soybean oil, and biodiesel, and (ii) domestic policies related to biofuels, such as an introduction of biofuel mandates. Both sets of issues can have important consequences to the Argentinean economy. The simulations indicate that increases in international prices of biofuels and feedstocks would increase Argentina's gross domestic product and social welfare. Increases in international prices of ethanol and corn also can benefit Argentina, but to a lesser extent. The domestic mandates for biofuels, however, would cause small losses in economic output and social welfare because they divert part of biodiesel and feedstock from exports to lower-return domestic consumption. An increase in the export tax on either feedstock or biodiesel also would lead to a reduction in gross domestic product and social welfare, although government revenue would rise. - Highlights: ► Argentina is one of the largest biodiesel producer and exporter using soybeans. ► Economy-wide impacts are assessed using a CGE model for Argentina. ► Policies simulated are feedstock and biodiesel price change, and domestic mandates. ► Increases in international prices of biofuels and feedstock benefit the country. ► Domestic mandates for biofuels cause small losses in economic output

These roads differed in traffic volume and surrounding landscape management conditions. We also investigated the influence of environmental variables (mean monthly air temperature and monthly total rainfall on the incidence of road kills. Two people monitored the roads on foot (1 000-m line transects, 3 times a month (36 samples per road. We found 2 024 vertebrate road killed specimens representing 61 species (7 amphibians, 15 reptiles, 32 birds, and 7 mammals. The toad Rhinella fernandezae was the most frequently killed species (n = 1307, 64.57%. NR168 had a higher incidence of vertebrate road kills, particularity for amphibians, whereas birds had a higher incidence of road kills on PR1. We found a positive correlation between precipitation and temperature with vertebrate road kills on PR1. We suggest that vertebrate road mortality is a very serious problem for the conservation of the biodiversity in Santa Fe Province-Argentina, therefore implementing mitigation measures will be necessary.Se estudió la mortalidad de vertebrados en 2 rutas (RP1: Ruta Provincial N° 1 y RN168: Ruta Nacional N° 168 de la Provincia de Santa Fe (Argentina desde octubre de 2007 hasta agosto de 2008.

    2016-01-01

    This article first outlines that Argentina produces an important part of its hydrocarbon consumption and comment various aspects of this production: hydrocarbons are at the heart of the Argentinian energetic model; conventional hydrocarbon reserves are however decreasing; the public operator remains the main actor even though the market is opened to multinational companies. The article then describes the crisis faced by this energetic model: the energy balance is now a burden; the increasing unbalance between production and consumption can be explained by supply-related as well as demand-related factors; authorities must intervene on hydrocarbon prices and subsidize the oil price on the domestic market. It appears that the future for hydrocarbons in Argentina relies on non-conventional hydrocarbons. Bio-fuels, a key sector of the Argentinian economy, are a matter of trade dispute with the EU and the USA. Apart from hydroelectricity (some new projects are planned), renewable energies are very few developed in Argentina. Appendices propose a graph of the distribution of energy consumption among the different sources, a map indicating locations of the main exploited hydrocarbon deposits, a presentation of mechanisms implemented to subsidize hydrocarbon production

    In January 2009 during an oil well logging task in Rincon de los Sauces, Province of Neuquen, Argentina, and, as a result of the temporary loss of control of a 137 Cs sealed source of 92,5 GBq (2,5 Ci), two workers were allegedly exposed to ionizing radiation. The Health Emergency Coordination System in Neuquen activated the Radiological Emergency Intervention System of the Nuclear Regulatory Authority (NRA). An initial assessment of the accident scenario and the involved persons was performed. Two workers were were transfer to Buenos Aires for a biodosimetry evaluation. In Buenos Aires, the Burn Hospital performed the first diagnostic and therapeutic approach of the radioinduced skin injuries. The NRA estimated the biological absorbed doses and the studies of telethermography. The Italian Hospital was in charge of the studies using ultrasonography and Eco- Doppler. As a result of the multidisciplinary evaluation performed, one of the workers was diagnosed with superficial radioinduced dermatitis. The mentioned intervention highlighted the importance of multidisciplinary and multiparametric work for the evaluation of a radiological accident, as well as for the diagnosis and early treatment of the exposed persons.

    The 1977 Caucete (San Juan) earthquake considered in the present paper occurred near the Sierra Pie de Palo in the Sierras Pampeanas tectonic province of western Argentina. In the study reported, coseismic surface deformation is combined with seismic observations (main shock and aftershocks, both teleseismic and local data) to place constraints on the geometry and slip of the main fault responsible for the 1977 earthquake. The implications of the 1977 event for long-term crustal shortening and earthquake recurrence rates in this region are also discussed. It is concluded that the 1977 Caucete earthquake was accompanied by more than 1 m of vertical uplift.

    Full Text Available ABSTRACT Thelastomatidae is one of the largest families parasitizing insects, within the order Oxyurida. In this work we reported parasitism in nymphs and adults of Neocurtilla claraziana by two different thelastomatid species as a part of a field survey on agricultural pests. Nymphs and adults of this insect were isolated from grasslands of Buenos Aires State, Argentina using a tensio-active solution. The nematode species Gryllophila skrjabini Sergiev, 1923 and Cephalobellus magalhaesi Schwenk, 1926 are briefly described and measurements are given. Both nematodes are reported for the first time in Argentina with C. magalhaesi being the second isolation of this species in the world. Neocurtilla clarziana is a new host record for G. skrjabini.

    Full Text Available En este artículo se examinarán las transformaciones espaciales operadas en el Hospital Posadas y sus barrios adyacentes durante el ciclo de violencia política y dictadura militar en Argentina y su inscripción en las memorias de sus trabajadores y habitantes. El Hospital Posadas, ubicado en la localidad de Haedo, en la provincia de Buenos Aires, fue epicentro de un proceso de radicalización política hasta el golpe de Estado de 1976. Tras el golpe, funcionó en sus dependencias un centro clandestino de detención donde estuvieron personas cautivas en condición de desaparecidas mientras se seguían desarrollando las prácticas habituales relativas al centro de salud. Simultáneamente, en sus barrios adyacentes se desenvolvió una intensa represión política. Se considera aquí que el espacio constituye uno de los marcos sociales fundamentales de la memoria colectiva y que en sus permanencias y transformaciones se materializan, a la vez, las memorias sociales de los actores que luchan por dotar de sentido el pasado. Se entiende que, por ello, este análisis permitirá historizar y comprender el proceso de violencia política en la zona a partir de los cambios operados en la topografía del Hospital y del barrio y de su impacto en las memorias de sus trabajadores y habitantes.

    Levels of glyphosate were determined in water, soil and sediment samples from a transgenic soybean cultivation area located near to tributaries streams of the Pergamino-Arrecifes system in the north of the Province of Buenos Aires, Argentina. Field work took into account both the pesticide application and the rains occurring after applications. The pesticide was analysed by HPLC-UV detection, previous derivatization with 9-fluorenylmethylchloroformate (FMOC-Cl). In addition, SoilFug multimedia model was used to analyse the environmental distribution of the pesticides. In the field, levels of glyphosate in waters ranged from 0.10 to 0.70 mg/L, while in sediments and soils values were between 0.5 and 5.0 mg/Kg. Temporal variation of glyphosate levels depended directly on the time of application and the rain events. The results obtained from the application of the model are in accordance with the values found in the field. - Glyphosate concentrations in the environment from a region where little information exists about this and intensive cultivation activities predominate in large areas.

    2015-04-01

    To understand the evolution of the "passive" continental margin in Argentina low temperature thermochronology is an appropriate method, which might lead to new insights in this area. The Tandilia System, also called Sierras Septentrionales, is located south of the Río de la Plato Craton in eastern Argentina in the state of Buenos Aires. North of the hills the Salado basin is located whereas the Claromecó basin is situated south of the mountain range. In contrary to most basins along the South American "passive" continental margin, the Tandilia-System and the neighbouring basins trend perpendicular to the coast line. The topography is fairly flat with altitudes up to 350 m. The igneous-metamorphic basement is pre-Proterozoic in age and build up of mainly granitic-tonalitic gneisses, migmatites, amphibolites, some ultramafic rocks and granitoid plutons. It is overlain by a series of Neoproterozoic to early Paleozoic sedimentary rocks (Cingolani 2011), like siliciclastic rocks, dolostones, shales and limestones (Demoulin 2005). The aim of the study is to quantify the long-term landscape evolution of the "passive" continental margin in eastern Argentina in terms of thermal, exhumation and tectonic evolution. For that purpose, samples were taken from the basement of the Sierra Septentrionales and analyzed with the apatite fission-track method. Further 2-D thermokinematic modeling was conducted with the computer code HeFTy (Ketcham 2005; Ketcham 2007; Ketcham et al. 2009). Because there are different hypotheses in literature regarding the geological evolution of this area two different models were generated, one after Demoulin et al. (2005) and another after Zalba et al.(2007). All samples were taken from the Neoproterozoic igneous-metamorphic basement. Apatite fission-track ages range from 101.6 (9.4) to 228.9 (22.3) Ma, and, therefore, are younger than their formation age, indicating all samples have been thermally reset. Six samples accomplished enough confined

    Introduction Postpartum depression is a prevalent disorder with negative consequences for women, infants, and the family as a whole. Most studies of this disorder have been conducted in Western countries, and studies from developing countries are few. In this paper, we report the first – as far as we are aware – study of the prevalence and risk factors associated with postpartum depressive symptoms in Argentina. Materials and methods The study participants were 86 women attending 6 week checkups, (range 4–12 weeks) postpartum at a private health care center in the metropolitan area of Buenos Aires. The women completed the Edinburgh Postnatal Depression Scale (EPDS) and a questionnaire collecting demographic and obstetric data. Data were described as proportions (percentages). Differences between proportions were assessed with chi-squared tests. To control for possible confounders, we fitted bivariate logistic regression models in which the dependent variable was an EPDS sum score of depressive symptoms. A total of 32 women (37.2%) had an EPDS score of ≥10, 16 (18.6%) had a score between 10 and 12, and 16 (18.6%) had a score of ≥13. In our sample, an EPDS score of ≥10 was significantly associated with multiparity (odds ratio [OR] =3.58; 95% confidence interval [CI]: 1.13–11.30; P=0.030), pregnancy complications (OR =3.40; 95% CI: 1.03–11.26; P=0.045), labor complications (OR =11.43; 95% CI: 1.71–76.61; P=0.012), cesarean section (OR =4.19; 95% CI: 1.10–16.01; P=0.036), and incomplete breast-feeding (OR =5.00; 95% CI: 1.42–17.54; P=0.012). Conclusion Our results indicate that postpartum depression may be prevalent in Argentina, and may be associated with incomplete breast-feeding, cesarean section, perinatal complications and multiparity. The prevalence and risk factors for postpartum depression has not been described previously and is a considerable health-related problem among women. Argentinian health professionals should be aware of the high

    Radiation sterilization of human tissues in Argentina was a consequence of health care products sterilization by gamma radiation. Radiation technology was implemented in 1970 when the first multipurpose gamma facility was built at the Ezeiza Atomic Centre of CNEA. Organ and tissue transplantation is a well established effective therapy that saves lives and significantly improves the quality of life. Ionizing radiation is used for sterilization in order to provide clinically safe tissue for therapeutic purposes of implantation in every patient in need. Argentina radiation and tissue banking activity started in 1993 with the establishment of two tissue banks using radiation under the IAEA programme of technical cooperation, a skin bank and a bone one. Additionally to this start, other tissue banks have adopted tissue sterilization by irradiation. The compatible tissues sterilized with this methodology are mainly skin (frozen, glycerolized), bone (lyophilized, frozen), and amniotic membrane (glycerolized, frozen, dehydrated). The donation and transplant of human organ, tissue and cells is regulated and coordinated by the National Institute Unique Central Coordinator of Ablation and Implant (INCUCAI). In regards to radiation and nuclear safety, physical protection and nuclear non-proliferation issues are regulated and contorted by the Nuclear Regulatory Authority (ARN). Eight tissue banks use gamma radiation for sterilization of human tissues (6 musculoskeletal, 1 skin and 1 amniotic membrane). Argentina has participated actively in several IAEA projects regarding radiation and tissue banking program, and it has been selected by the IAEA to host the Regional Training Centre for the Latin American region. The following activities were implemented: regional training courses in Buenos Aires, face to face (five) and virtual (four) modalities; collaboration on several materials related to tissue banking and radiation sterilization of tissue allograft, codes of practice for

    Full Text Available INTRODUCTION: The Argentinean AIDS Program estimates that 110,000 persons are living with HIV/AIDS in Argentina. Of those, approximately 40% are unaware of their status, and 30% are diagnosed in advanced stages of immunosuppression. Though studies show that universal HIV screening is cost-effective in settings with HIV prevalence greater than 0.1%, in Argentina, with the exception of antenatal care, HIV testing is always client-initiated. OBJECTIVE: We performed a pilot study to assess the acceptability of a universal HIV screening program among inpatients of an urban public hospital in Buenos Aires. METHODS: Over a six-month period, all eligible adult patients admitted to the internal medicine ward were offered HIV testing. Demographics, uptake rates, reasons for refusal and new HIV diagnoses were analyzed. RESULTS: Of the 350 admissions during this period, 249 were eligible and subsequently enrolled. The enrolled population was relatively old compared to the general population, was balanced on gender, and did not report traditional high risk factors for HIV infection. Only 88 (39% reported prior HIV testing. One hundred and ninety (76% patients accepted HIV testing. In multivariable analysis only younger age (OR 1.02; 95%CI 1.003-1.05 was independently associated with test uptake. Three new HIV diagnoses were made (undiagnosed HIV prevalence: 1.58%; none belonged to a most-at-risk population. CONCLUSIONS: Our findings suggest that universal HIV screening in this setting is acceptable and potentially effective in identifying undiagnosed HIV-infected individuals. If confirmed in a larger study, our findings may inform changes in the Argentinean HIV testing policy.

    Nowadays, air pollution is a severe environmental problem in China. To investigate the effects of ambient air pollution on health, a time series analysis of daily outpatient and inpatient visits in 2015 were conducted in Shenzhen (China). Generalized additive model was employed to analyze associations between six air pollutants (namely SO2, CO, NO2, O3, PM10, and PM2.5) and daily outpatient and inpatient visits after adjusting confounding meteorological factors, time and day of the week effects. Significant associations between air pollutants and two types of hospital visits were observed. The estimated increase in overall outpatient visits associated with each 10 µg/m3 increase in air pollutant concentration ranged from 0.48% (O3 at lag 2) to 11.48% (SO2 with 2-day moving average); for overall inpatient visits ranged from 0.73% (O3 at lag 7) to 17.13% (SO2 with 8-day moving average). Our results also suggested a heterogeneity of the health effects across different outcomes and in different populations. The findings in present study indicate that even in Shenzhen, a less polluted area in China, significant associations exist between air pollution and daily number of overall outpatient and inpatient visits.

This evolutionary approach facilitates the analysis of the Argentinian export economy from an unusual perspective, namely the building of the domestic market, and the development of a sector which was not oriented to the export trade, in a province other than Buenos Aires or la Pampa. It is contended that both aspects were intimately related, since the export boom helped to consolidate a national State which favoured the expansion of the Tucuman sugar industry through reailroad construction, finance aid and tariff protection.

    Este artículo analiza el origen y consolidación de la industria azucarera en Tucumán entre 1860 y 1914. Su evolución permite contemplar el período de esplendor de la economía exportadora argentina desde perspectivas poco habituales: la construcción del mercado interno y el desarrollo de producciones no destinadas al comercio externo en una provincia del interior, en lugar de Buenos Aires o la Pampa. El estudio prueba que ambos aspectos estaban íntimamente relacionados, pues el citado boom exportador ayudó a consolidar un Estado nacional que, en última instancia, propició el auge de la manufactura cañera tucumana mediante el tendido de ferrocarriles, ayudas financieras y protección arancelaria.

    PM10 and PM2.5 samples were taken using a Gent sampler to characterize the atmospheric aerosol of Buenos Aires metropolitan area. A total of 114 samples were collected from October 2005 to October 2006 at one urban site, every third day, for 24 h. Samples were analyzed by neutron activation, and black carbon and mass concentration were determined. In both fractions, elemental and gravimetric mass concentrations were compared with historical data. Enrichment factors, backward trajectories and factor analysis were calculated. The attribution of pollution sources is discussed. (author)

    In 1989, the US Department of Energy (DOE) responded to the need to redirect resources from weapons production to environmental restoration and waste management by establishing the Office of Environmental Management (EM) and delegated to this office the responsibility of cleaning up the US nuclear weapons complex. Now in its eight year, EM's mission has three central facets: (1) to assess, remediate, and monitor contaminated sites and facilities; (2) to store, treat, and dispose of waste from past and current operations; and (3) to develop and implement innovative technologies for environmental cleanup. To this end, EM has established domestic and international cooperative technology development programs, including one with the Republic of Argentina. Cooperating with Argentine scientific institutes and industries meets US cleanup objectives by: (1) identifying and accessing Argentine EM-related technologies, thereby leveraging investments and providing cost-savings; (2) improving access to technical information, scientific expertise, and technologies applicable to EM needs; and (3) fostering the development of innovative environmental technologies by increasing US private sector opportunities in Argentina in EM-related areas

    The number of graduate programs in Optoelectronics in Argentina is scarce. The current Optics and Photonics Education Directory lists only three programs. One of them was launched in 2001 in the Facultad de Ingeniería (College of Engineering), Universidad de Buenos Aires (UBA). This was the first graduate program in the field, leading to a Master Degree in Optoelectronics. This decision arose from the demand of telecommunications industries and several estate- or private-funded research institutions working with us in the fields of lasers, optics, remote sensing, etc. A great bonus was the steady work, during several decades, of research groups in the College on the development of different type of lasers and optical non destructive tests and their engineering applications. As happened in many engineering graduate programs in Argentina at that time, few non full-time students could finish their studies, which called for 800 hours of traditional lecture-recitation classes, and the Master Thesis. In recent years Argentine Education authorities downsized the Master programs to 700 hours of blended learning and we redesigned the Graduate Optoelectronic Engineering Program to meet the challenge, dividing it in two successive one year programs, the first aimed at a professional training for almost immediate insertion in the labor market (called Especialización en Ingeniería Optoelectrónica), and the second (called Maestría en Ingeniería Optoelectrónica y Fotónica) aimed at a more academic and research target to comply with the UBA standards for Master degrees. The present work is a presentation of the new program design, which has begun in the current year.

    The first step from the neuropsychology in Argentina was in 1883 with the thesis of Antonio Piñeiro about the brain localization of the language and vision disorders, only few years after Broca. The aim of this work has been to describe the development of the neuropsychology in Argentina and its relation with the psychology, neurology and psychiatry. The first period was into the neurology with its French school in?uence. In 1907, Jose Ingeniero published in French his book about "amusia", Cristofredo Jakob the "folia neurobiologica" where he described the organization of the human brain, Vicente Dimitri in 1933 his book "aphasia" and Bernardo de Quiros in 1959 his works about dyslexia. The psychiatry at the hospices with the German influence from Jakob developed to the modern neuropsychiatry with Juan Carlos Goldar. The argentine school of psychology by the holism and the psychoanalysis influence do not accept the neuropsychology until 1960 where was included at the school of psychology from the university of Buenos Aires (UBA) with the first linguistics works of Juan Azcoaga. At the 80, began the North American influence of the neurology with authors like Carlos Mangone (dementia), Ramon Leiguarda (apraxia), Sergio Starkstein (depression and apathy) and Ricardo Allegri (memory and Alzheimer). In 1982 the Argentine Neuropsychological Society was founded and in 1987 was the working group of dementia from the Argentine Neurological Society. At this moment, Aldo Ferreres organized the chair of neuropsychology at the school of psychology (UBA). Nowadays, the growing as discipline is in context of the psychology, neurology and psychiatry in the way of the recent cognitive neurosciences.

    Full Text Available Nacida a fines del siglo 19, Mar del Plata ha devenido —en el término de un siglo— en balneario por excelencia de Buenos Aires y de la Argentina en general. La cultura estival de la playa la ha hecho evolucionar desde un turismo elitista hacia un turismo de masas, impulsando el desarrollo de espacios y estructuras destinadas a alojamiento y ocio para cerca de 3 millones de personas cada año. Con un espacio urbano fuertemente segregativo y en expansión, el litoral está sometido a una fuerte presión antrópica, a una erosión contínua y a una degradación en la calidad de sus aguas. La crisis social, económica y política que atraviesa Argentina crea condiciones poco favorables para la actividad turística y ensombrece el futuro de Mar del Plata.

    To describe the process of approval and implementation of a comprehensive smoke-free law in the province of Santa Fe, Argentina, between 2005 and 2009. Review of the Santa Fe smoke-free legislation, articles published in local newspapers and documentation on two lawsuits filed against the law, and interviews with key individuals in Santa Fe. Efforts to implement smoke-free policies in Santa Fe began during the 1990s without success, and resumed in 2005 when the provincial Legislature approved the first 100% smoke-free subnational law in Argentina. There was no strong opposition during the discussions within the legislature. As in other parts of the world, pro-tobacco industry interests attempted to block the implementation of the law using well known strategies. These efforts included a controversy media campaign set up, the creation of a hospitality industry association and a virtual smokers' rights group, the introduction of a counterproposal seeking modification of the law, the challenge of the law in the Supreme Court, and the proposal of a weak national bill that would 'conflict' with the subnational law. Tobacco control advocates sought media attention as a strategy to protect the law. Santa Fe is the first subnational jurisdiction in Latin America to have enacted a comprehensive smoke-free policy following the recommendations of the World Health Organization (WHO) Framework Convention on Tobacco Control. After 3 years of implementation, pro-tobacco industry forces failed to undermine the law. Other subnational jurisdictions in Argentina, as well as in Mexico and Brazil are following the Santa Fe example.

    The aging rate in Taiwan is the second highest in the world. As the population ages quickly, the prevalence of dementia increases rapidly. There are some studies that have explored the association between air pollution and cognitive decline, but the association between air pollution and dementia has not been directly evaluated. This was a case-control study comprising 249 Alzheimer's disease (AD) patients, 125 vascular dementia (VaD) patients, and 497 controls from three teaching hospitals in northern Taiwan from 2007 to 2010. Data of particulate matter Bayesian maximum entropy was used to estimate the individual exposure level of air pollutants, which was then tertiled for analysis. Conditional logistic regression models were used to estimate adjusted odds ratios (AORs) and 95% confidence intervals between the association of PM10 and ozone exposure with AD and VaD risk. The highest tertile of PM10 (≥49.23 μg/m(3)) or ozone (≥21.56 ppb) exposure was associated with increased AD risk (highest vs. lowest tertile of PM10: AOR = 4.17; highest vs. lowest tertile of ozone: AOR = 2.00). Similar finding was observed for VaD. The association with AD and VaD risk remained for the highest tertile PM10 exposure after stratification by APOE ɛ4 status and gender. Long-term exposure to the highest tertile of PM10 or ozone was significantly associated with an increased risk of AD and VaD.

    In some countries, "Big Events" like crises and transitions have been followed by large increases in drug use, drug injection and HIV/AIDS. Argentina experienced an economic crisis and political transition in 2001/2002 that affected how people use their time. This paper studies how time use changes between years 2001 and 2004, subsequent to these events, were associated with drug consumption in poor neighbourhoods of Greater Buenos Aires. In 2003-2004, 68 current injecting drug users (IDUs) and 235 young non-IDUs, aged 21-35, who lived in impoverished drug-impacted neighbourhoods in Greater Buenos Aires, were asked about time use then and in 2001. Data on weekly hours spent working or looking for work, doing housework/childcare, consuming drugs, being with friends, and hanging out in the neighbourhood, were studied in relation to time spent using drugs. Field observations and focus groups were also conducted. After 2001, among both IDUs and non-IDUs, mean weekly time spent working declined significantly (especially among IDUs); time spent looking for work increased, and time spent with friends and hanging out in the neighbourhood decreased.We found no increase in injecting or non-injecting drug consumption after 2001. Subjects most affected by the way the crises led to decreased work time and/or to increased time looking for work--and by the associated increase in time spent in one's neighbourhood--were most likely to increase their time using drugs. Time use methods are useful to study changes in drug use and their relationships to every day life activities. In these previously-drug-impacted neighbourhoods, the Argentinean crisis did not lead to an increase in drug use, which somewhat contradicts our initial expectations. Nevertheless, those for whom the crises led to decreased work time, increased time looking for work, and increased time spent in indoor or outdoor neighbourhood environments, were likely to spend more time using drugs. These data suggest that

    The activity concentrations of both natural (238U and 232Th chains and 40K) and anthropogenic (137Cs) radionuclides down along the soil profile have been determined in soil samples collected from inland and coastal areas of the La Plata River, located in the Northeastern region of the Province of Buenos Aires, Argentina. These studies were complemented with 57Fe Mössbauer spectroscopy characterization, pH, texture and organic carbon content measurements. From Mössbauer results, the sample compositions differ from one area to the other. Spectra from both soil samples are dominated by the Fe3+ paramagnetic signal. For soil samples from the coastal area, the α-Fe2O3 contribution is lower, Fe3O4 was not detected, and the relative areas of each spectral contribution are nearly constant with depth. For samples from the inland area, the Fe3+ paramagnetic fraction increases up to 82%, mainly at the expense of the magnetically ordered phase. The main observed activity originates from the decay of 40K (540-750 Bq/kg), followed by 238U (60-92 Bq/kg) and 232Th (37-46 Bq/kg) chains. The activity of 235U was in all the cases lower than the detection limit (LD = 0.02 Bq/kg). The only determined anthropogenic nuclide was 137Cs, arising from the fallout of the Southern Hemisphere nuclear weapon tests. Three of the observed differences in the depth distributions can be described by the dispersion-convection model. A correlation between the natural nuclide activities and the Mössbauer relative fractions was found, whereas no correlation was found between the 137Cs profile and the relative fraction of Fe3O4 or with other iron species.

    We investigated temporal trends in BMI, and assessed hypothesized predictors of trends including socio-economic position (SEP) and province-level economic development, in Argentina. Using multivariable linear regression, we evaluated cross-sectional patterning and temporal trends in BMI and examined heterogeneity in these associations by SEP and province-level economic development with nationally representative samples from Argentina in 2005 and 2009. We calculated mean annual changes in BMI for men and women to assess secular trends. Women, but not men, exhibited a strong cross-sectional inverse association between SEP and BMI, with the lowest-SEP women having an average BMI 2.55 kg/m(2) greater than the highest-SEP women. Analysis of trends revealed a mean annual increase in BMI of 0.19 kg/m(2) and 0.15 kg/m(2) for women and men, respectively, with slightly greater increases occurring in provinces with greater economic growth. No significant heterogeneity in trends existed by individual SEP. BMI is increasing rapidly over time in Argentina irrespective of various sociodemographic characteristics. Higher BMI remains more common in women of lower SEP compared with those of higher SEP.

    Echinococcosis is a zoonosis caused by tapeworms of the genus Echinococcus. Echinococcus granulosus sensu lato (s. l.) has a world-wide distribution and its transmission is primarily maintained in a synanthropic cycle with dogs as definitive hosts and livestock species as intermediate hosts. However, many wild canids also function as definitive hosts for E. granulosus s. l. Echinococcosis in humans is mainly caused by E. granulosus sensu stricto (s. s.) G1 genotype. In the present work, we expanded the epidemiological study on echinococcosis reported cases in Pampas fox (Lycalopex gymnocercus) to provide a prevalence estimate for rural areas of southern Buenos Aires province, Argentina. Ninety-five whole intestines were analyzed using the sedimentation and counting technique with a result of 83 foxes (87.37%) harboring at least one helminth species. E. granulosus s. l. adults were found in one Pampas fox (1.05%). These adult helminthes were E. granulosus s. s. (G1) according to the genotyping analysis of a 450-bp region of the mitochondrial cytochrome c oxidase subunit 1 (cox1) gene. Copyright © 2016 Elsevier B.V. All rights reserved.

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

    1998-01-01

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

  8. Air pollution and mortality: Determination of a quantitative association

    Ostro, B.

    1994-01-01

    Over the last few decades, several epidemiologic studies have reported associations between daily concentrations of ambient particulate matter and mortality among the general population. Among these studies, statistically significant relationships have been found using several alternative measures of particulate matter including total suspended particulates (TSP) for particles of all sizes], fine particles (particles less than 25 microns in diameter), British smoke (BS), coefficient of haze (COH), and sulfates. None has involved measurement of the mass of particulate matter less than 10 microns in diameter (PM10), the metric used by the U.S. Environmental Protection Agency (EPA) in the National Ambient Air Quality Standards. The studies have been conducted in several different cities and seasons, thereby incorporating a wide range of climates, chemical compositions of particulate matter, and populations. The epidemiologic. investigations have used two principal study designs: time-series and cross-sectional. Time-series analysis examines changes in daily mortality rates within a specific area as air pollution levels fluctuate. A cross-sectional analysis compares differences in mortality rates across several cities at a selected point or period of time. This paper seeks to examine the air pollution-mortality association in view of these criteria, with particular focus on the consistency of the association. Replication of results in other environments and populations is a powerful test before causality can be inferred. The check for consistency will be accomplished by reviewing and comparing the results of the more recent empirical studies. Ultimately, the results of these calculations are presented in terms of the percent increase in mortality associated with changes in PM 10 . After examining the consistency of the associations, some of the other criteria will be briefly discuss

    Full Text Available Los objetivos del presente artículo son describir el sistema de justicia juvenil en la provincia de Buenos Aires (Argentina desde las perspectivas jurídica y ejecutiva, y comunicar avances científicos globales en la evaluación de los jóvenes que cometen actos disociales. En la provincia de Buenos Aires el sistema ha sido profundamente modificado en los últimos 15 años siguiendo las premisas de la Convención Internacional sobre los Derechos del Niño y dejando relegado el modelo del Patronato, que había regido previamente. Las instituciones encargadas de la ejecución de la intervención dispuesta por el Poder Judicial dependen actualmente de la Subsecretaria de Niñez y Adolescencia del Ministerio de Desarrollo Social y constan de centros cerrados, centros con régimen de semilibertad y centros de intervención ambulatoria (medidas alternativas a la prisión, tales como suspensión de juicio a prueba o tareas comunitarias. Las ciencias relacionadas con la salud mental y con el comportamiento vienen contribuyendo a la identificación de diversos factores influyentes en la conducta disocial y con el diseño de tipos de intervención para cada nivel de prevención. Sin embargo, hay una distancia importante entre las potencialidades del estado actual delconocimiento y la implementación. En las condiciones expuestas, queda configurado un período de transición que aún requiere optimización de la política de infancia con ajustes legislativos, judiciales y administrativos y con la capitalización de los aportes científicos.

  13. [Inequities in health: socio-demographic and spatial analysis of breast cancer in women from Córdoba, Argentina].

    Tumas, Natalia; Pou, Sonia Alejandra; Díaz, María Del Pilar

    To identify sociodemographic determinants associated with the spatial distribution of the breast cancer incidence in the province of Córdoba, Argentina, in order to reveal underlying social inequities. An ecological study was developed in Córdoba (26 counties as geographical units of analysis). The spatial autocorrelation of the crude and standardised incidence rates of breast cancer, and the sociodemographic indicators of urbanization, fertility and population ageing were estimated using Moran's index. These variables were entered into a Geographic Information System for mapping. Poisson multilevel regression models were adjusted, establishing the breast cancer incidence rates as the response variable, and by selecting sociodemographic indicators as covariables and the percentage of households with unmet basic needs as adjustment variables. In Córdoba, Argentina, a non-random pattern in the spatial distribution of breast cancer incidence rates and in certain sociodemographic indicators was found. The mean increase in annual urban population was inversely associated with breast cancer, whereas the proportion of households with unmet basic needs was directly associated with this cancer. Our results define social inequity scenarios that partially explain the geographical differentials in the breast cancer burden in Córdoba, Argentina. Women residing in socioeconomically disadvantaged households and in less urbanized areas merit special attention in future studies and in breast cancer public health activities.

Sierras Pampeanas Centrales (SPC mountains are located in Córdoba and San Luis provinces (Argentina and represent an area of unique biogeographic importance. In this paper we provide a synthesis about the knowledge of diversity and altitudinal distribution of anurans that inhabit SPC mountains. We compiled a species list through different information sources (field data, biological collections and bibliography. Using this information we characterize altitudinal distribution range of each species and analyze associations between species richness and composition and altitude gradient. We recorded 24 amphibians species belonging to five families. These species are heterogeneously distributed over the altitude gradient of SPC. We detect a linear negative relationship between altitude and species richness and defined assemblages associated with different altitude sectors. The results obtained in the paper represent basic information that will be useful to evaluate anthropogenic impact on this particular and fragile mountain system.

    2011-11-01

    A dozen multi-day pollution episodes occur from October to February in Hanoi, Vietnam due to prolonged anticyclonic conditions established after the northeast monsoon surges (cold surges). These winter pollution episodes (WPEs) account for most of the 24-h PM{sub 10} exceedances and the highest concentrations of gaseous pollutants in Hanoi. In this study, WPEs were investigated using continuous air quality monitoring data and information on upper-air soundings and air mass trajectories. The 24-h pollutant concentrations are lowest during cold surges; concurrently rise thereafter reaching the highest levels toward the middle of a monsoon cycle, then decline ahead of the next cold surge. Each monsoon cycle usually proceeds through a dry phase and a humid phase as Asiatic continental cold air arrives in Hanoi through inland China then via the East China Sea. WPEs are associated with nighttime radiation temperature inversions (NRTIs) in the dry phase and subsidence temperature inversions (STIs) in the humid phase. In NRTI periods, the rush hour pollution peak is more pronounced in the evening than in the morning and the pollution level is about two times higher at night than in daytime. In STI periods, broad morning and evening traffic peaks are observed and pollution is as high at night as in daytime. The close association between pollution and winter monsoon meteorology found in this study for the winter 2003-04 may serve as a basis for advance warning of WPEs and for forecasting the 24-h pollutant concentrations. - Highlights: {yields} Dozen pollution episodes from Oct. to Feb in Hanoi associated with anticyclones after monsoon surges. {yields} 24-h concentrations of PM{sub 10}, SO{sub 2}, NO{sub 2}, CO rise after surge and decline ahead of the next. {yields} Episodes caused by nighttime radiation and subsidence inversions in dry and humid monsoon phases. {yields} Distinct diurnal variations of pollutant concentrations observed in the two periods. {yields} Close

    Full Text Available We studied hantavirus seroprevalence and virus variability in rodent populations in Diego Gaynor, northwest of Buenos Aires province, Argentina. Rodent samplings were conducted in railroads and cropfield borders in March and July 1999, September and December 2000, and March 2001. Antibody detection was performed by an enzyme link immunosorbent assay (ELISA, using the recombinant nucleoprotein of Andes (AND virus as antigen. Tissue samples were taken from positive antibody individuals in order to confirm the presence of hantavirus genomic material and to identify virus genotypes. Akodon azarae was the most abundant species, followed by Oligoryzomys flavescens, while Calomys laucha and C. musculinus were rarely caught. We found a rate of seroprevalence of 9.3% for a total sample of 291 A. azarae and 13.5% for 37 O. flavescens. After molecular analyses of hantavirus, we confirmed the presence of hantavirus genomic material in 16 individuals with ELISA (+ results and two individuals with ELISA (-. Four amplimers for each species were sequenced and compared to the corresponding sequences of representative hantaviruses. We identified the AND Cent Lec from three O. flavescens, and the Pergamino virus from four A. azarae and from one O. flavescens. A. azarae males had higher seroprevalence than females, and heavier individuals showed higher seroprevalence than lighter ones. We did not find seroprevalence differences according to sex in O. flavescens, although this result may have been produced by the low sample size. The lowest seroprevalence was found in a period of high rodent density, when juveniles prevailed in the population. We found higher seroprevalences than those detected in previous studies for other localities of central Argentina where cases of hantavirus pulmonary syndrome (HPS have been reported. The presence of AND Cent Lec virus in rodent populations of the study area, which is responsible of HPS cases in central Argentina, suggests

Resultante de um balanço bibliográfico e de uma incursão exploratória na pesquisa de campo tanto em São Paulo como em Buenos Aires, o artigo pretende apontar para aspectos específicos do fenômeno, combinando olhares e perspectivas que cruzam as dimensões migratórias, geracionais e de gênero.The article aims to discuss a new immigration pattern from Bolivia to Brazil and to Argentina, specially related with precarious jobs and precarious labour market. This pattern can be considered as apparently new when compared with the classical forms of immigrants integration in Brazil, during all 20th century. The consequences of recent immigration from Bolivia to Brazil can be seen in São Paulo where these immigrants are confined to the sewing sector and precarious jobs in hidden small factories, where they often live with their families. The article is based on bibliographical informations and an exploratory field research in São Paulo and Buenos Aires about Bolivian immigrant labour, especially in the sewing sector, trying to understand some of its particularities. Specifically, the article treats with the phenomenon of immigration, precarious labour markets, generational and gender relations, as part of a global pattern introduced by the so called “Chinese cost”.

    This study investigated the acute effects of exposure to air pollution on ventricular tachyarrhythmias (VTAs) in an East Asian population. The association between air pollution and VTA has not yet been studied in an East Asian country affected by the Asian dust phenomenon, which worsens air quality. The study cohort consisted of 160patients with implantable cardioverter defibrillator (ICD) devices in the Seoul metropolitan area who were followed for 5.5±3.8years. We used ICD records of VTAs and matched these with hourly measurements of air pollutant concentrations and meteorological data. Fine particle mass and gaseous air pollution plus temperature and relative humidity were measured hourly during the study period. During the study period, 1064 VTA events including 204 instances of ventricular fibrillation (VF) were observed. We found a statistically significant association between overall VTA events and SO 2 (lag 24h; OR 1.49, 95%CI 1.16-1.92, p=0.002), PM 10 (lag 2h; OR 2.56, 95%CI 2.03-3.23, pair pollution and VTA were observed in a metropolitan area of an East Asian country. Exposures to SO 2 , PM 10 , NO 2 , and CO were significantly associated with VTAs in ICD patients with SHD. Copyright © 2017 Elsevier B.V. All rights reserved.

    The Chilean, Argentinean and Brazilian power matrixes presented in the last two decades a growth of the non-renewable energy sources share, especially fossil sources, mainly in installed capacity and in a lesser degree in energy production. Greenpeace and the European Renewable Energy Council have elaborated a reference energy scenario together with a scenario analyzing the institution of ample measures for the promotion of renewable energy sources. Feed-in tariffs and auction or bidding mechanisms implemented in Brazil and Argentina and the renewable portfolio standard implemented in Chile allied with the wind industry state in these countries indicate that Chile and Argentina will fulfill the 2020 wind power installed capacity predicted in the reference scenarios, while Brazil will reach the energy revolution scenario prediction. Important energy policy changes are required if the Chile and Argentina energy revolution scenarios wind power installed capacity are to become a reality in 2020. (author)

    Full Text Available ABSTRACT The Argentina-Alzheimer's disease neuroimaging initiative (Arg-ADNI study is a longitudinal prospective cohort of 50 participants at a single institution in Buenos Aires, Argentina. Longitudinal assessments on a neuropsychological test battery were performed on 15 controls, 24 mild cognitive impairment (MCI patients and 12 Alzheimer's disease (AD dementia patients. In our study population, there was a high prevalence of positive AD biomarkers in the AD group, 92.3% (12/13; and a low prevalence in the normal controls, 20%; almost half (48% of the patients diagnosed with MCI had positive amyloid detection. After a one year, the significant differences found at baseline on neuropsychological testing were similar at the follow-up assessment even though the AD group had significantly altered its functional performance (FAQ and CDR. The exception was semantic fluency, which showed greater impairment between the AD group and MCI and normal controls respectively. For these tests, the addition of AD biomarkers as a variable did not significantly alter the variations previously found for the established clinical group's model.

    Ostro, B

    1994-07-01

    Over the last few decades, several epidemiologic studies have reported associations between daily concentrations of ambient particulate matter and mortality among the general population. Among these studies, statistically significant relationships have been found using several alternative measures of particulate matter including total suspended particulates (TSP) for particles of all sizes], fine particles (particles less than 25 microns in diameter), British smoke (BS), coefficient of haze (COH), and sulfates. None has involved measurement of the mass of particulate matter less than 10 microns in diameter (PM10), the metric used by the U.S. Environmental Protection Agency (EPA) in the National Ambient Air Quality Standards. The studies have been conducted in several different cities and seasons, thereby incorporating a wide range of climates, chemical compositions of particulate matter, and populations. The epidemiologic. investigations have used two principal study designs: time-series and cross-sectional. Time-series analysis examines changes in daily mortality rates within a specific area as air pollution levels fluctuate. A cross-sectional analysis compares differences in mortality rates across several cities at a selected point or period of time. This paper seeks to examine the air pollution-mortality association in view of these criteria, with particular focus on the consistency of the association. Replication of results in other environments and populations is a powerful test before causality can be inferred. The check for consistency will be accomplished by reviewing and comparing the results of the more recent empirical studies. Ultimately, the results of these calculations are presented in terms of the percent increase in mortality associated with changes in PM{sub 10}. After examining the consistency of the associations, some of the other criteria will be briefly discuss.

    Full Text Available Inocutis jamaicensis (Murrill Gottlieb, J.E. Wright & Moncalvo was identified as the basidiomycetous species associated with ‘hoja de malvón’ grapevine disease in Argentina. Macro and micro-morphological characteristics of fruit bodies corresponded to those described for the white-rotting fungus associated with native plant species and Eucalyptus globulus Labill. planted in Uruguay. Monokariotic isolates were obtained from basidiospores produced by fruit bodies of I. jamaicensis collected from Vitis vinifera L. and E. globulus. Dikaryons and fruit bodies produced by pairing monokaryotic mycelium suggest that all these isolates belong to the same species. The analysis of RFLP of the dikaryon produced by pairing monokaryons derived from V. vinifera and E. globulus revealed fragments that corresponded to each monokaryon, confirming that isolates from Vitis mated with those from Eucalyptus. In order to compare grapevine and Uruguayan isolates, RFLPs from ITS region generated by restriction digestion with Alu I, Hae III, Hha I, Msp I and Taq I were performed. Differences found in some restriction pattern could reflect a certain degree of variability between dikariotic isolates, probably related with a particular lifestyle, host specificity or geographic origin.

    The Fiambala range is located in the central south part of the province of Catamarca, Western Sierras Pampeanas, Argentina. It is largely conformed by Precambrian metamorphic rocks, a Cambrian granitic intrusive, Ordovician basic and ultra basic rocks and epi zonal Carboniferous granites (Los Ratones, El Salto and Ayacucho Granites). The Carboniferous granites are sub alkaline, weakly peraluminous, high silica (except for the porphyritic facies of Los Ratones granite) and moderately enriched in K. Contents of trace elements and REE indicate that El S alto and Ayacucho granites and the granular facies of Los Ratones granite have characteristics of evolved and differentiated granite associated with hydrothermal systems. The variations of trace elements, particularly Sn, W, U, Rb, Ba, Zr and Sr suggest that they correspond to granites with mineralization potential. Genetically linked to these granites there are Sn, W, U and minor base metals greisen deposits. The hydrothermal process that yield to these deposits involved two main alteration stages, beginning with alkali metasomatism follow by greissenization. According to the isotopic ages the hydrothermal processes postdate about 1 Ma the magmatic activity. The analyses of the granites and the associated greisen deposits confirm that the post orogenic carboniferous magmatism is the major metallogenetic control of the ore deposits from the studied area. This metallogenetic control could be a useful tool in prospecting similar deposits in the rest of the Western Sierras Pampeanas. (Author)

    Full Text Available Direct forms of confrontation represent one of the main features of the social conflict in Argentina in the xxI century. Particularly, the hostile outbursts have constituted a dynamic that is present throughout the decade. The public system of railway transportation of passengers in the metropolitan area of Buenos Aires was one of the social spaces with the most recurrence of this kind of collective action. Between 2003 and 2009 a cycle of hostile outbursts took place, in which groups of passengers attacked goods and employees of the concessionary enterprise –and in some cases security forces involved– showing its social dissatisfaction with the quality of service. In this paper, we expose a hypothetical frame in order to explain these events while promoting a conceptual debate about this kind of action.Las formas directas de confrontación representan una de las características salientes de la conflictividad social en la Argentina del siglo XXI. En particular, los estallidos de hostilidad constituyen una dinámica presente a lo largo de toda la década. El transporte ferroviario de pasajeros del área metropolitana de Buenos Aires se erigió en uno de los espacios sociales con gran recurrencia de este tipo de acciones. Entre 2003 y 2009 se desarrollaron una serie de estallidos en los cuales grupos de pasajeros atacaban bienes y trabajadores de las empresas prestatarias –y en ocasiones a las fuerzas de seguridad que intervenían– con el objeto de expresar su disconformidad con la forma de prestación del servicio. En este artículo exponemos los resultados de nuestra investigación sobre dichos episodios, presentando un marco hipotético-conceptual que da cuenta de los mismos y promueve en simultáneo un debate conceptual sobre esta forma de acción directa.

    To determine the prevalence of metabolic syndrome among adolescents in a city in Argentina and to establish its association with certain risk factors linked to life style. Cross-sectional study of a representative sample of 532 middle and high school students from 11-20 years of age (mean: 15.3 years; females: 60%) in the city of Posadas, province of Misiones, Argentina, from July-October 2005. Surveys were conducted of individuals' dietary habits, anthropometric measurements, sedentary levels, blood pressure readings, and laboratory results. Metabolic syndrome was diagnosed if three or more of the following conditions were present: fasting glucose > or = 110 mg/dL; triglycerides > or = 110 mg/dL; HDL cholesterol 90th percentile; and waist circumference > 90th percentile. The prevalence of metabolic syndrome was 4.5%; significantly higher among males than among females (7.5% vs. 2.5%; P = 0.006) and among the 15-20 year old age group than among the 11-14 year old group (6.3% vs. 2.5%; P = 0.037). Of the adolescents, 44.7% had one or more components of metabolic syndrome. The risk of metabolic syndrome among obese adolescents was elevated (odds ratio = 119.73; 95% confidence interval: 27.6-519.41). Dietary habits and frequency of food consumption were similar among students with and without metabolic syndrome; however, the first group consumed fattening foods more frequently. Of all the adolescents in the sample, 84.8% were sedentary (100% of those with metabolic syndrome). In the city of Posadas, some 1 400 students suffer from metabolic syndrome and about 13 000 have at least one metabolic syndrome component. Joint efforts by the state government and the community are needed to change dietary habits and increase physical activity, mainly among boys, those 15-20 years of age, and the obese, to reverse the situation and reduce the morbidity/mortality that results from metabolic syndrome.

A través del escrutinio de distintas crónicas periodísticas, se reconstruirá el calendario de actividades del ilustre huésped, se desvelará su acogida por parte del campo intelectual bonaerense de las décadas del veinte y del treinta, y se observarán sus polémicas declaraciones de apoliticidad a la luz del proyecto de fascitización proyectado desde la Italia de Mussolini hacia las “colonias” de ultramar. This article examines the landings of Pirandello in Argentina as a key episode to think about his role and reception in Buenos Aires during his two South American tournées in 1927 and 1933. Through the reading of different journalistic Chronicles, we propose firstly to reconstruct the guest’s calendar, secondly to study his welcome by the Buenos Aires intellectual field of the 20’s and 30’s and, finally, to link his apolitical speeches with the Italian fascism interested in imposing its control over the Latin-American “colonies".

    Yellow anacondas (Eunectes notaeus) are large, semiaquatic boid snakes found in wetland systems in South America. These snakes are commercially harvested under a sustainable management plan in Argentina, so information regarding population structuring can be helpful for determination of management units. We evaluated genetic structure and migration using partial sequences from the mitochondrial control region and mitochondrial genes cyt-b and ND4 for 183 samples collected within northern Argentina. A group of landscape features and environmental variables including several treatments of temperature and precipitation were explored as potential drivers of observed genetic patterns. We found significant population structure between most putative population comparisons and bidirectional but asymmetric migration in several cases. The configuration of rivers and wetlands was found to be significantly associated with yellow anaconda population structure (IBD), and important for gene flow, although genetic distances were not significantly correlated with the environmental variables used here. More in-depth analyses of environmental data may be needed to fully understand the importance of environmental conditions on population structure and migration. These analyses indicate that our putative populations are demographically distinct and should be treated as such in Argentina's management plan for the harvesting of yellow anacondas. PMID:22675425

    Full Text Available This article examines how emotions are understood, in deeply gendered ways, within gender and clientelism debates in Argentina. By looking at the case study of the voluntary network of neighborhood representatives of Plan Vida, which distributes food aid in the Province of Buenos Aires, I distinguish two ways of conceiving affects in grassroots women’s political participation. While the first one emphasizes the management of the external expression of emotions as part of doing politics, the second one considers affective labour in a given urban territory as fostering connections among actors, creating social capital and allowing the flow of relevant information. The conclusion suggests that the second approach gives greater relevance to the possibilities of agency and transforming relations of domination of these women doing politics at the local level.

    This study observed the relationship between air pollutants and ischemic cardiac diseases such as angina and acute myocardial infarction in a representative cardiovascular center emergency room in Sao Paulo, Brazil. Daily emergency room admissions to the Institute of the Heart of the university of Sao Paulo, as well as data concerning daily air pollutant levels and meteorological variables, were collected from January 1994 to august 1995. Generalized additive Poisson regressions were fitted to the logarithm of the expected values of total emergency room visits due to angina or acute myocardial infarction, controlling for smooth functions of season and weather and indicators for days of the week. All investigated pollutants were positively associated with ischemic cardiovascular disease emergency room visits, and the time lags were relatively short, but only CO presented in effect that was statistically significant. An interquartile range increase n CO was associated with an increase of 6.4% (95% CI: 0.7-12.1) in daily angina or acute myocardial infarction emergency room visits. This result did not change when estimates were done using linear models and natural cubic plines. This study showed that air pollution has a role in cardiovascular morbidity in Sao Paulo, reinforcing the necessity for air pollutant mission-controlling polices in urban areas

  17. The regulatory control of radioactive sources in Argentina

    International Nuclear Information System (INIS)

    Rojkind, R.H.

    1998-01-01

    Argentina has been conducting nuclear activities for more than forty years, and had established a Regulatory Authority as early as in 1956. Procedures for compliance monitoring and enforcement have been in use in the regulatory control of radioactive sources, and regulatory standards and regulations were in force in Argentina before the accident in Goiania. The conclusions drawn from the Goiania accident encouraged the Argentine authorities to improve some regulatory procedures and helped to enhance the quality of the regulatory process. As a result, the effectiveness of the control of spent radioactive sources has gradually increased, and enforcement actions to prevent radioactive sources ending up in the public domain have improved. Lessons learned in Argentina from the accident in Goiania are presented as well as the main characteristics of an effective enforcement programme to prevent radiological accidents when radioactive sources are used for industrial, medical, research and teaching purposes.

Direct medical costs were obtained using administrative databases. Direct nonmedical and indirect costs were obtained from a semistructured questionnaire. Indirect costs included work absenteeism, permanent work disability, and housework lost for housewives, using the human capital approach. Costs are expressed in 2002 US dollars per patient per year.Results: A total of 165 patients (84% females, of mean age 61 ± 15 years and with a mean disease duration of 8.5 ± 8.3 years were included. Mean total direct medical costs were US$1862 (95% confidence interval [CI] 828–2899. Mean direct nonmedical costs were US$222 (95% CI 149–294. Mean indirect costs were US$1008 (95% CI 606–1412. The annual mean total cost was US$3093 without biologics. Hospitalizations represented 73% of total direct medical costs while drugs and outpatient procedures represented 16% and 8% of total direct medical costs, respectively. Sixty percent of the total costs were related to direct medical costs, while indirect costs represented 33% of total costs.Conclusion: In our population, annual mean total costs in the prebiologic therapy era were mainly driven by direct medical costs.

    2011-01-01

    Triatoma infestans is the main vector of Chagas' disease in South America between latitudes 10°S and 46°S. A multilocus microsatellite data set of 836 individuals from 27 populations of T. infestans, from all its range of distribution in Argentina, was analyzed. Our results favor the hypothesis of two independent migration events of colonization in Argentina and secondary contacts. The majority of the populations of the western provinces of Catamarca, La Rioja, San Juan and the west of Cordoba province, had almost no shared ancestry with the rest of the populations analyzed. Probably those populations, belonging to localities close to the Andean region, could have been established by the dispersal line of T. infestans that would have arrived to Argentina through the Andes, whereas most of the rest of the populations analyzed may have derived from the dispersal line of T. infestans in non-Andean lowlands. Among them, those from the provinces of Formosa, Chaco, Santiago del Estero and Santa Fe shared different percentages of ancestry and presented lower degree of genetic differentiation. The migratory movement linked to regional economies and possibly associated with passive dispersal, would allow a higher genetic exchange among these populations of T. infestans. This study, using microsatellite markers, provides a new approach for evaluating the validity of the different hypotheses concerning the evolutionary history of this species. Two major lineages of T. infestans, an Andean and non-Andean, are suggested. PMID:21224874
