Cystic echinococcosis is a highly endemic parasitic zoonosis that is present in the Southern Cone countries of America. For several decades, various prevention and control programmes have been implemented in different countries and regions, with varying results. In Uruguay, a new control programme was implemented in 2006 that employed new strategies for canine diagnosis and treatment, dog population control, diagnosis in humans, epidemiological surveillance, and health education, including community participation. The control programme in Uruguay addresses the control and surveillance of the disease from a holistic perspective based on Primary Health Care, which has strengthened the community's participation in developing and coordinating activities in an interdisciplinary manner. Similarly, the control programme that is currently implemented is based on a risk-focused approach. The surveillance and control measures were focused on small villages and extremely poor urban areas. In this study, the strategies used and the results obtained from 2008-2013 are analysed and discussed.

Background FCTC Article 11 Guidelines recommend that health warning labels (HWLs) should occupy at least 50% of the package, but the tobacco industry claims that increasing the size would not lead to further benefits. This article reports the first population study to examine the impact of increasing HWL size above 50%. We tested the hypothesis that the 2009/2010 enhancement of the HWLs in Uruguay would be associated with higher levels of effectiveness. Methods Data were drawn from a cohort of adult smokers (≥18 years) participating in the International Tobacco Control (ITC) Uruguay Survey. The probability sample cohort was representative of adult smokers in 5 cities. The surveys included key indicators of HWL effectiveness. Data were collected in 2008/09 (pre-policy: Wave 2) and 2010/11 (post-policy: Wave 3). Results Overall, 1746 smokers participated in the study at Wave 2 (n=1,379) and Wave 3 (n=1,411). Following the 2009/2010 HWL changes in Uruguay (from 50% to 80% in size), all indicators of HWL effectiveness increased significantly [noticing HWLs: odds ratio (OR)=1.44, p=0.015; reading HWLs: OR=1.42, p=0.002; impact of HWLs on thinking about risks of smoking: OR=1.66, p<0.001; HWLs increasing thinking about quitting: OR=1.76, p<0.001; avoiding looking at the HWLs: OR=2.35, p<.001; and reports that HWLs stopped smokers from having a cigarette “many times”: OR=3.42, p<0.001]. Conclusions The 2009/2010 changes to HWLs in Uruguay, including a substantial increment in size, led to increases of key HWL indicators, thus supporting the conclusion that enhancing HWLs beyond minimum guideline recommendations can lead to even higher levels of effectiveness.

Defending strong tobacco packaging and labelling regulations in Uruguay: transnational tobacco control network versus Philip Morris International.

Crosbie, Eric; Sosa, Particia; Glantz, Stanton A

2018-03-01

Describe the process of enacting and defending strong tobacco packaging and labelling regulations in Uruguay amid Philip Morris International's (PMI) legal threats and challenges. Triangulated government legislation, news sources and interviews with policy-makers and health advocates in Uruguay. In 2008 and 2009, the Uruguayan government enacted at the time the world's largest pictorial health warning labels (80% of front and back of package) and prohibited different packaging or presentations for cigarettes sold under a given brand. PMI threatened to sue Uruguay in international courts if these policies were implemented. The Vazquez administration maintained the regulations, but a week prior to President Vazquez's successor, President Mujica, took office on 1 March 2010 PMI announced its intention to file an investment arbitration dispute against Uruguay in the International Centre for the Settlement of Investment Disputes. Initially, the Mujica administration announced it would weaken the regulations to avoid litigation. In response, local public health groups in Uruguay enlisted former President Vazquez and international health groups and served as brokers to develop a collaboration with the Mujica administration to defend the regulations. This united front between the Uruguayan government and the transnational tobacco control network paid off when Uruguay defeated PMI's investment dispute in July 2016. To replicate Uruguay's success, other countries need to recognise that strong political support, an actively engaged local civil society and financial and technical support are important factors in overcoming tobacco industry's legal threats to defend strong public health regulations. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Slates from Uruguay: a traditional natural stone

NASA Astrophysics Data System (ADS)

Morales Demarco, M.; Oyhantçabal, P.; Stein, K.-J.; Siegesmund, S.

2012-04-01

Slates were traditionally used as roofing material or for cladding worldwide and also in Uruguay. In regions where this resource was easily mined, the widespread application of slates in constructions resulted in the development of characteristic cultural landscapes. The application of slates in a wider sense is nowadays open for all uses of dimensional stone, compared to the restricted use as roofing or cladding material in the past. This has been achieved by the discovery and mining of new deposits within the last 25 years worldwide. Furthermore, the optimization of mining techniques that allows the excavation of larger blocks and the technical development for further handling of the blocks has contributed to an open spectrum of applications. The slate deposits from Uruguay are associated with the Neoproterozoic thrust and fold belt of the Dom Feliciano Belt. The slates are linked to calc-silicate strata in a greenschist facies volcano-sedimentary sequence and the deposits are located in the limb of a regional fold, where bedding and cleavage are parallel. The main lithotype is a layered and fine-grained calcareous phyllite with a quite diverse palette of colors: light green, grey, dark grey, reddish and black. The mined slate is split into slabs 0.5 - 2cm thick. The technical properties were investigated in a very systematic way with respect to the new European standards, showing values comparable to those registered for internationally known slates. In the past, the average production in Uruguay was around 4000 tons/year and a historical maximum of 13,000 tons was reached in 1993. The oscillations in the regional demand were the cause of several flourishing and decay cycles in the activity, but our investigation shows a considerable volume of indicated resources and therefore a very good potential. Exploration for colors and qualities and quantification of reserves is a prerequisite for the development of the sector.

To assess the impact of different health warning labels (HWL). Data from the International Tobacco Control Survey (ITC Survey) were analyzed from adult smokers in Brazil, Uruguay and Mexico, each of which used a different HWL strategy (pictures of human suffering and diseased organs; abstract pictorial representations of risk; and text-only messages, respectively). Main outcomes were HWL salience and cognitive impact. HWLs in Uruguay (which was the only country with a HWL on the front of the package) had higher salience than either Brazilian or Mexican packs. People at higher levels of educational attainment in Mexico were more likely to read the text-only HWLs whereas education was unassociated with salience in Brazil or Uruguay. Brazilian HWLs had greater cognitive impacts than HWLs in either Uruguay or Mexico. HWLs in Uruguay generated lower cognitive impacts than the text-only HWLs in Mexico. In Brazil, cognitive impacts were strongest among smokers with low educational attainment. This study suggests that HWLs have the most impact when they are prominent (i.e., front and back of the package) and include emotionally engaging imagery that illustrates negative bodily impacts or human suffering due to smoking.

The purpose of this study was to evaluate the availability and stability of fluoride in children's toothpastes in Uruguay. Six commercial brands of children's toothpaste available in Uruguay were tested. Analyses were made when the dentifrices were purchased (fresh samples) and after one year of storage (aged samples). Total fluoride (TF) and total soluble fluoride (TSF) concentrations were determined using an ion specific electrode. Four of the children's dentifrices showed TF concentration similar to that specified on the package. Three products showed similar concentrations of TF and TSF with no variations after the one-year storage period. Two dentifrices showed an initial insoluble fluoride concentration greater than 50 percent, which increased with toothpaste aging. Most tested toothpastes showed a decrease in the soluble fluoride content with aging. The high quantity of insoluble fluoride found in two tested dentifrices may compromise their anti-caries efficacy.

Uruguay's military physicians. Cogs in a system of state terror.

PubMed

Bloche, M G

The military junta that ruled Uruguay until March 1985 was engaged in a systematic program of clandestine detention and torture of political detainees. Bloche went to Uruguay in December 1985 on behalf of the American Association for the Advancement of Science to investigate claims that physicians collaborated in this program. He reports on the extent to which evidence supported allegations that physicians engaged in performing clinical examinations on detainees that yielded information used for planning torture, prepared pathological reports that covered up acts of brutality, failed to provide adequate medical assistance, designed a prison regimen to harm inmates' mental health, and abused neuroleptic drugs. He concludes that, although evidence regarding some of the allegations was inconclusive, the investigation proved overall that clinicians played a significant role in the Uruguayan apparatus of physical and psychological torture.

Double burden of undernutrition and obesity in Uruguay.

Severi, Cecilia; Moratorio, Ximena

2014-12-01

Uruguay is at an advanced stage of the epidemiologic transition; like other Latin American countries, it bears a nutritional double burden composed of undernutrition and overweight or obesity. The aim was to estimate whether a double burden of nutritional problems exists in Uruguay and to identify if governmental programs and policies for nutrition take this double burden into account. Existing studies were reviewed, and other data were processed specifically for the purpose of this article. Several data sources were used to include a broad, comprehensive population range. The prevalence of stunting in children aged <2 y is 10.9%. There is a high frequency of obesity, which increases with age (9.5% in children <2 y old, 18.8% in those aged 6 y, 20.4% in those aged 11 y, 26.6% in those aged 13-15 y, and 35.3% in adults). In addition, 13.8% of women start pregnancy underweight and the rate of obesity increases during pregnancy from 36.7% at the beginning to 46.5% at the end. Anemia is very frequent in the selected population we examined, as follows: 31% of children <2 y old and 20.9% of pregnant women in their third trimester. An obese mother with a stunted child are present in 6.3% of households; 1.9% of stunted children are obese at age 6 y and 3.1% are obese at the age of 11. Multiple logistic analysis applied to children <2 y showed an association between stunting and obesity (OR: 2.0; 95% CI: 1.2, 3.6). The data suggest that there is a nutritional double burden in Uruguay. This nutritional burden is similar to that of other countries in the region. This important public issue should be tackled, and it should be addressed in early infancy. © 2014 American Society for Nutrition.

Tucci, Carlos Eduardo Morelli; Clarke, Robin Thomas; Collischonn, Walter; da Silva Dias, Pedro Leite; de Oliveira, Gilvan Sampaio

2003-07-01

This paper describes a procedure for predicting seasonal flow in the Rio Uruguay drainage basin (area 75,000 km2, lying in Brazilian territory), using sequences of future daily rainfall given by the global climate model (GCM) of the Brazilian agency for climate prediction (Centro de Previsão de Tempo e Clima, or CPTEC). Sequences of future daily rainfall given by this model were used as input to a rainfall-runoff model appropriate for large drainage basins. Forecasts of flow in the Rio Uruguay were made for the period 1995-2001 of the full record, which began in 1940. Analysis showed that GCM forecasts underestimated rainfall over almost all the basin, particularly in winter, although interannual variability in regional rainfall was reproduced relatively well. A statistical procedure was used to correct for the underestimation of rainfall. When the corrected rainfall sequences were transformed to flow by the hydrologic model, forecasts of flow in the Rio Uruguay basin were better than forecasts based on historic mean or median flows by 37% for monthly flows and by 54% for 3-monthly flows.

A Chilling Example? Uruguay, Philip Morris International, and WHO's Framework Convention on Tobacco Control.

The World Health Organization's Framework Convention on Tobacco Control (FCTC) is the first international public health treaty to address the global spread of tobacco products. Ethnographic research at the fourth meeting of the FCTC's Conference of the Parties in Uruguay highlights the role of the FCTC in recalibrating the relationship between international trade and investment agreements and those of global public health. Specifically, we chart the origins and development of the Punta del Este Declaration, tabled by Uruguay at the conference, to counter a legal request by Philip Morris International, the world's largest tobacco transnational, for arbitration by the International Centre for the Settlement of Investment Disputes over Uruguay's alleged violations of several international trade and investment treaties. We argue that medical anthropologists should give greater consideration to global health governance and diplomacy as a potential counterweight to the 'politics of resignation' associated with corporate capitalism. © 2014 by the American Anthropological Association.

Traditional application of slates in Uruguay

NASA Astrophysics Data System (ADS)

Morales Demarco, Manuela; Cardenes Van den Eynde, Víctor

2017-04-01

Commercial slates in Uruguay are represented by dolomitic and pelitic slates, which are known in the local market with the generic name of "piedra laja". The dolomitic slates, or more precisely the "slaty dolomitic semipelites" and "slaty dolomitic metacarbonate rocks" (following the nomenclature of the British Geological Survey for metamorphic rocks, Robertson 1999), dominates the production since 1960. The mining started in a quarry called "Libro Gigante", which means "giant book" in Spanish, as the slaty cleavage of these rocks is almost vertical, which resembles a book when looked from far away. These slates integrate the Lavalleja Group, a unit that comprises the schist belt of the Neoproterozoic Dom Feliciano Belt that crops out in south-eastern Uruguay. According to Morales Demarco et al (2013), there are two active slate mining districts in this region: the northern, called "Arroyo Minas Viejas Mining District", from where light grey, light and dark green and green-red slate varieties are mined, and the southern called "Arroyo Mataojo Mining District" and where only dark grey slates are extracted. Few kilometres eastern from these districts, and still in Lavalleja Group, a quarry of slaty dolomitic pelite is found with sporadic production. Far to the east, the slaty muscovitic pelites of Rocha Group are mined from one quarry in "Puntas del Chafalote". The traditional applications of these slates in the country are as façade cladding and floor slabs, both indoor and outdoor. The potential use of the dolomitic slates as roofing slates has been investigated and discarded by Morales Demarco et al (2013), as the slabs resulting from splitting are too thick (0.5 to 2 cm) and thus too heavy for this application. The parameter that controls the fissility of slates is the mass value (Bentz and Martini, 1968; DIN EN 12326-2, 2000) and is very important to determine their potential applications. It takes into account the number of mica layers per mm and the average

Latin American special project: kidney health cooperation project between Uruguay and Bolivia.

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

Tobacco cessation intervention for pregnant women in Argentina and Uruguay: study protocol

PubMed Central

2013-01-01

Background Argentina and Uruguay are among the countries with the highest proportion of pregnant women who smoke. The implementation of an effective smoking cessation intervention would have a significant impact on the health of mothers and infants. The “5 A’s” (Ask, Advise, Assess, Assist, Arrange) is a strategy consisting of a brief cessation counseling session of 5–15 minutes delivered by a trained provider. The “5 A’s” is considered the standard of care worldwide; however, it is under used in Argentina and Uruguay. Methods We will conduct a two-arm, parallel cluster randomized controlled trial of an implementation intervention in 20 prenatal care settings in Argentina and Uruguay. Prenatal care settings will be randomly allocated to either an intervention or a control group after a baseline data collection period. Midwives’ facilitators in the 10 intervention prenatal clinics (clusters) will be identified and trained to deliver the “5 A’s” to pregnant women and will then disseminate and implement the program. The 10 clusters in the control group will continue with their standard in-service activities. The intervention will be tailored by formative research to be readily applicable to local prenatal care services at maternity hospitals and acceptable to local pregnant women and health providers. Our primary hypothesis is that the intervention is feasible in prenatal clinics in Argentina and Uruguay and will increase the frequency of women receiving tobacco use cessation counseling during pregnancy in the intervention clinics compared to the control clinics. Our secondary hypotheses are that the intervention will decrease the frequency of women who smoke by the end of pregnancy, and that the intervention will increase the attitudes and readiness of midwives towards providing counseling to women in the intervention clinics compared to the control clinics.

Neuronavigation is the application of image guidance to neurosurgery where the position of a surgical tool can be displayed on a preoperative image. Although this technique has been used worldwide in the last ten years, it was never applied in Uruguay due to its cost. In an ongoing project, the Engineering Faculty (Universidad de la República), the Hospital de Clínicas (Medicine Faculty - Universidad de la República) and the Regional Hospital of Tacuarembó are doing the first experimental trials in neuronavigation. In this project, a prototype based on optical tracking equipment and the open source software IGSTK (Image Guided Surgery Toolkit) is under development and testing.

Vernonia plantaginoides (Less.) Hieron, previously known as Vernonia squarrosa, is a rhizomatous subshrub with purple flowers that is prevalent in the natural grassland of Uruguay, Argentina, and southern Brazil. We report an outbreak of V. plantaginoides (yuyo moro) intoxication in sheep in Treinta y Tres Department, northeastern Uruguay. A total of 54 of 463 (12%) recently weaned lambs died 2-7 days after entering a natural pasture that had been invaded by sprouting V. plantaginoides The first cases were found dead. Affected lambs showed marked jaundice, edema of the face, ears, and eyelids, and severe photodermatitis. At the autopsies of 3 lambs, the carcass was yellow, the liver was enlarged with a marked acinar pattern ("nutmeg liver"), and hemorrhages were observed on serous membranes. Microscopic lesions were characterized by diffuse periacinar hepatocellular necrosis and cholemic nephrosis. Three female lambs were experimentally dosed with the aerial parts of V. plantaginoides collected immediately after the outbreak. The lamb that was dosed once with 40 g/kg body weight died after 36 h with severe hepatic necrosis. The lamb dosed with 20 g/kg daily for 4 days showed clinical signs and microscopic lesions in the liver with multiple apoptotic hepatocytes in the periacinar zone. The third lamb, dosed with 30, 17, and 15 g/kg daily over 3 days, respectively, showed transient clinical signs and a rise in liver enzymes, but recovered, and no lesions were found postmortem. These results demonstrate that V. plantaginoides was responsible for severe field outbreaks of poisoning in sheep in Uruguay. © 2016 The Author(s).

Paleomagnetic and Tectonic studies in Uruguay: a brief synthesis of the last decade

NASA Astrophysics Data System (ADS)

Sanchez Bettucci, L.

2013-05-01

The paleomagnetic studies in Uruguay have been applied as a complementary tool to geological studies. Paleomagnetic data can be very useful for geodynamic reconstructions, fundamentally for determine the latitudinal tectonic transport, rotations of crustal blocks. This technique has been applied to Paleoproterozoic, Neoproterozoic and Paleozoic units. The geology of the Uruguayan territory is divided into four tectonic units of Uruguay that include a) the Piedra Alta tectonostratigraphic terrane (PATT) and b) Nico Pérez tectonostratigraphic terrane (NPTT), separated by the Sarandí del Yí high-strain zone. Both terranes are well exposed in the Río de La Plata craton (RPC) and have paleoproterozoic ages, the last was reworked in Neoproterozoic times (metacraton). The most thoroughly investigated Neoproterozoic sections are located in the eastern and southeastern regions of Uruguay. The c) Dom Feliciano Belt shows a tectonic evolution from back-arc to foreland basin characterized by fold-and-thrust, thick-skinned belts developed during the Brasiliano/Pan-African orogenic cycle. And finally d) The high metamorphic grade Punta del Este terrane where its most notable feature is their African affinity. There is a significant shortage of geochemical and geochronological data for the existing geological complexity.

A New "Shield of the Weak": Continued Paternalism of Domestic Violence Services in Uruguay.

PubMed

Bloom, Allison

2018-03-01

Drawing on ethnographic and historical research, this article illuminates the limitations of the Uruguayan domestic violence services system. In spite of how advocates in Uruguay successfully used a human rights platform to secure legislation and services, this system now faces significant critique. Using Iris Marion Young's work on the "logic of masculinist protection" and historical parallels in Uruguay's welfare system, I discuss how a paternalistic approach may be to blame. I highlight how this paternalism contributes to the paternalism that problematically underlies gendered violence-reinforcing rather than addressing oppressive ideologies and structures that impede improving conditions for women.

Argentina and Uruguay have a high prevalence of smoking during pregnancy, as well as of secondhand smoke (SHS) exposure. In this secondary analysis of a trial to implement brief smoking cessation counseling during antenatal care in Argentina and Uruguay, we aim to evaluate the effects of the intervention on the rates of self-reported SHS exposure at home and at work, and on attitudes recalled by non-smoker women enrolled in the intervention group compared with the control group. We randomly assigned (1:1) 20 antenatal care clusters in Argentina and Uruguay to receive a multifaceted intervention to implement brief smoking cessation counseling, which also included questions and counseling regarding SHS exposure, or to receive the standard of care. There was not a statistically significant difference between groups of the intervention's effect (reduction of exposure to SHS) on any of the three exposure outcome measures (exposure at home, work or other indoor areas) or on the attitudes of women regarding exposure (avoiding breathing SHS and having rooms where smoking is forbidden). This analysis shows that we should not expect reductions in SHS exposure with this modest intervention alone. To achieve such reductions, strategies engaging partners and other household members may be more effective.

To determine the prevalence, correlates and changes in secondhand smoke (SHS) exposure over the period after comprehensive smoke-free policy implementation in two Latin American countries. Data were analysed from population-based representative samples of adult smokers and recent quitters from the 2008 and 2010 waves of the International Tobacco Control Policy Evaluation Survey in Mexico (n = 1766 and 1840, respectively) and Uruguay (n = 1379 and 1411, respectively). Prevalence of SHS exposure was estimated for regulated venues, and generalized estimating equations were used to determine correlates of SHS exposure. Workplace SHS exposure in the last month was similar within and across countries (range: Mexico 20-25%; Uruguay 14-29%). At the most recent restaurant visit, SHS exposure was lower where comprehensive smoke-free policies were implemented (range: Uruguay 6-9%; Mexico City 5-7%) compared with Mexican cities with weaker policies, where exposure remained higher but decreased over time (32-17%). At the most recent bar visit, SHS exposure was common (range: Uruguay 8-36%; Mexico City 23-31%), although highest in jurisdictions with weaker policies (range in other Mexican cities: 74-86%). In Uruguay, males were more likely than females to be exposed to SHS across venues, as were younger compared with older smokers in Mexico. Comprehensive smoke-free policies are more effective than weaker policies, although compliance in Mexico and Uruguay is not as high as desired.

Uruguay is a South American country (3241003 inhabitants) where renal replacement treatment is universally available. The aim of this study was to analyze the incidence and outcome of peritonitis, and the causative organisms and their sensitivity, in order to recommend an empiric initial antibiotic treatment. A retrospective descriptive study of all peritonitis during the period 2004-2005 was performed (144 peritonitis, 44% due to gram-positive bacteria). We conclude that the high prevalence of methicillin-resistant coagulase-negative staphylococci justifies the use of vancomycin in the national empiric initial antibiotic protocols.

Fascioliasis is a pathogenic disease transmitted by lymnaeid snails and recently emerging in humans, in part due to effects of climate changes, anthropogenic environment modifications, import/export and movements of livestock. South America is the continent presenting more human fascioliasis hyperendemic areas and the highest prevalences and intensities known. These scenarios appear mainly linked to altitude areas in Andean countries, whereas lowland areas of non-Andean countries, such as Uruguay, only show sporadic human cases or outbreaks. A study including DNA marker sequencing of fasciolids and lymnaeids, an experimental study of the life cycle in Uruguay, and a review of human fascioliasis in Uruguay, are performed. The characterization of Fasciola hepatica from cattle and horses of Uruguay included the complete sequences of the ribosomal DNA ITS-2 and ITS-1 and mitochondrial DNA cox1 and nad1. ITS-2, ITS-1, partial cox1 and rDNA 16S gene of mtDNA were used for lymnaeids. Results indicated that vectors belong to Lymnaea neotropica instead of to Lymnaea viator, as always reported from Uruguay. The life cycle and transmission features of F. hepatica by L. neotropica of Uruguay were studied under standardized experimental conditions to enable a comparison with the transmission capacity of F. hepatica by Galba truncatula at very high altitude in Bolivia. On this baseline, we reviewed the 95 human fascioliasis cases reported in Uruguay and analyzed the risk of human infection in front of future climate change estimations. The correlation of fasciolid and lymnaeid haplotypes with historical data on the introduction and spread of livestock into Uruguay allowed to understand the molecular diversity detected. Although Uruguayan L. neotropica is a highly efficient vector, its transmission capacity is markedly lower than that of Bolivian G. truncatula. This allows to understand the transmission and epidemiological differences between Andean highlands and non

Differences by sex in tobacco use and awareness of tobacco marketing -Bangladesh, Thailand, and Uruguay, 2009.

PubMed

2010-05-28

The majority of the world's 1.3 billion tobacco users are men, but female use is increasing. To examine differences in tobacco use and awareness of tobacco marketing by sex, CDC and health officials in Bangladesh, Thailand, and Uruguay (among the first countries to report results) analyzed 2009 data from a newly instituted survey, the Global Adult Tobacco Survey (GATS). This report summarizes the results of that analysis, which indicated wide variation among the three countries in tobacco use, product types used, and marketing awareness among males and females. In Bangladesh and Thailand, use of smoked tobacco products was far greater among males (44.7% and 45.6%, respectively) than females (1.5% and 3.1%, respectively). In Uruguay, the difference was smaller (30.7% versus 19.8%). Use of smokeless tobacco products in Bangladesh was approximately the same among males (26.4%) and females (27.9%), but females were significantly more likely to use smokeless tobacco in Thailand (6.3% versus 1.3%), and use in Uruguay by either sex was nearly nonexistent. Males in Bangladesh were twice as likely as females to notice cigarette advertising (68.0% versus 29.3%), but the difference between males and females was smaller in Thailand (17.4% versus 14.5%) and Uruguay (49.0% versus 40.0%). In all three countries, awareness of tobacco marketing was more prevalent among females aged 15--24 years than older women. Comprehensive bans on advertising, sponsorship, and promotion of tobacco products, recommended by the World Health Organization (WHO), can reduce per capita cigarette consumption if enforced.

First approach to exhaust emissions characterization of light vehicles in Montevideo, Uruguay.

2018-03-15

According to Act No. 17283 of November 28th, 2000, air quality protection is a general concern in Uruguay. Road transport is the main emitter of nitrogen oxides (NO x ), as the National Inventory of Air Emissions 2006 stated. Actually, it is responsible for the emissions of 59.8% of NO x and 28% of carbon monoxide (CO). The number of households owning a car in Uruguay increased from 29% in 2005 to 39% in 2013, enhancing the importance of characterizing the vehicular emissions of the national fleet. In this paper, a first approach for this characterization is presented. It was carried out on a sample of 11 light vehicles currently in use in Montevideo city, Uruguay. On-road emissions measurements of nitrogen monoxide (NO), carbon monoxide (CO) and carbon dioxide (CO 2 ) were carried out for calculating the emission factors. The fitness of the set of calculated emission factors values to different probability distributions was tested. When possible, the 95% confidence intervals were obtained for the mean emission factors (CO: 2.0g/km±0.3g/km; NO: 0.05g/km±0.01g/km). This procedure was useful to obtaining accurate confidence intervals from a relatively small sample size. Finally, the link between atmospheric emissions and some other parameters of the tested vehicles was studied using a multivariate statistical tool, highlighting the strong increase in carbon monoxide emissions observed for low vehicles speeds and fuel efficiencies.

Uruguay Roselli 1938 and Rosellichnus, N. Ichnogenus: Two ichnogenera for clusters of fossil bee cells

USGS Publications Warehouse

Genise, Jorge F.; Bown, Thomas M.

1996-01-01

The systematics of the fossil bee nest ichnogenus Uruguay from the Uruguayan Cretaceous or lower Tertiary is reviewed and two new ichnospecies of a new ichnogenus, Rosellichnus, are proposed for fossil bee nests from the Miocene of the United Arab Emirates and Patagonian Argentina. Uruguay contains U. auroranormae(the ich‐notype) and U. rivasi, which differs from the type ichnospecies in having clustered cells arranged in three rows, with one central and two marginal rows of subparallel cells. No bee nest architecture known to us unequivocally fits with any ichnospecies described herein. Uruguay was constructed in the subsoil and may be of halictid origin; however, its large cell size, thick cell walls, and the presence of a vestibular cell do not fit the architecture of nests of extant halictids. Rosellichnus arabicus lacks the complete cavity surrounding the cell cluster that is typical in nests of Old World halictids, but it may, nonetheless, still be of halictid origin. R. pa‐tagonicus has an architecture more similar to nests of anthophorine bees than to those of Neotropical Halictidae. Therefore, the ichnogenus Rosellichnus may include both halictid and anthophorine constructions. Although the smooth inner cell walls, spiral cell caps, and clustering of cells indicate that both Uruguay and Rosellichnus are trace fossils of bee origin, it is likely that both represent nest architectures that are no longer employed by extant bees, or those that are as yet unknown. The paleoenvironments of both the Argentine and Emirates species of Rosellichnus indicate that the trace‐makers of this ichnogenus constructed their nests in open ground sandy soils.

During 5,230 trapping nights, 672 small mammals were trapped in the areas where most hantavirus pulmonary syndrome (HPS) cases occur in Uruguay. Yellow pygmy rice rats (Oligoryzomys flavescens) were the only rodents that showed evidence of antibodies to hantavirus, with a seroprevalence of 2.6%. The rodents were trapped in all the explored environments, and most of the seropositive rodents were found in habitats frequented by humans. Nucleotide sequences were obtained from four HPS case-patients and four yellow pygmy rice rats of the M genome segment. Sequence comparison and phylogenetic analysis showed that rodent-borne viruses and viruses from three HPS case-patients form a well-supported clade and share a 96.4% identity with the previously characterized Central Plata hantavirus. These results suggest that yellow pygmy rice rat (O. flavescens) may be the host for Central Plata, a hantavirus associated with HPS in the southern area of Uruguay.[ PMID:12890326

New Long-Term Care Policies in Latin America: The National System of Care in Uruguay.

2016-07-01

Uruguay is the Latin American country with the largest share of elderly population and it has the greatest pressure for formal long-term care services in the region. For this reason, last year the government approved a law creating a National System of Care. This article describes and analyzes the long-term care policy in the recently created National System of Care of Uruguay. The Director of the National System of Care was asked to complete a questionnaire with a description and management of long-term care programs. This information was completed with official information and peer-reviewed articles of long-term care in Uruguay. The National System of Care includes long-term care services. The main services are carried out through a cash-for-care system for home-based services, but in the future the benefits will expand to day centers and residential and nursing homes. The system follows international trends in terms of universality, services, and regulations dealing with care. However, the current and future financing is low, and this condition could undermine its development capacity. Copyright © 2016 AMDA – The Society for Post-Acute and Long-Term Care Medicine.

In Argentina and Uruguay, 10.3 and 18.3 %, respectively, of pregnant women smoked in 2005. Brief cessation counseling, based on the 5A’s model, has been effective in different settings. This qualitative study aims to improve the understanding of factors influencing the provision of smoking cessation counseling during pregnancy in Argentina and Uruguay. In 2010, we obtained prenatal care providers’, clinic directors’, and pregnant smokers’ opinions regarding barriers and promoters to brief smoking cessation counseling in publicly-funded prenatal care clinics in Buenos Aires, Argentina and Montevideo, Uruguay. We interviewed six prenatal clinic directors, conducted focus groups with 46 health professionals and 24 pregnant smokers. Themes emerged from three issue areas: health professionals, health system, and patients. Health professional barriers to cessation counseling included inadequate knowledge and motivation, perceived low self-efficacy, and concerns about inadequate time and large workload. They expressed interest in obtaining a counseling script. Health system barriers included low prioritization of smoking cessation and a lack of clinic protocols to implement interventions. Pregnant smokers lacked information on the risks of prenatal smoking and underestimated the difficulty of smoking cessation. Having access to written materials and receiving cessation services during clinic waiting times were mentioned as promoters for the intervention. Women also were receptive to non-physician office staff delivering intervention components. Implementing smoking cessation counseling in publicly-funded prenatal care clinics in Argentina and Uruguay may require integrating counseling into routine prenatal care and educating and training providers on best-practices approaches.

Cannabis clubs in Uruguay: The challenges of regulation.

PubMed

Queirolo, Rosario; Boidi, Maria Fernanda; Cruz, José Miguel

2016-08-01

The Uruguayan Cannabis Clubs (UCCs) constitute one of three ways to obtain cannabis under the new cannabis regulation laws. These organizations, formed by up to 45 adults and with a legal limit to grow up to 99 plants, appear to provide a safe method of procuring cannabis in a country that is trying to regulate aspects of cannabis production and distribution. This article describes the operations of the UCCs and the challenges these organizations face. The paper draws on data from in-depth interviews conducted with representatives of UCCs and conversations with government officials conducted between March and August of 2015. We collected information about membership, facilities and forms of organization, methods of cannabis cultivation and distribution, and activities within the community. This article describes how UCCs are formed, their resources, rules for cannabis production and distribution; and their relationships with government institutions and the community. Data show that UCCs face four main challenges: compliance with the extant regulation, financial sustainability, tolerance from the community, and collective action dilemmas. Organizational challenges are as frequent in Uruguay as in other country where cannabis clubs exist, however this paper shows that in order to be sustainable, UCCs need to address issues of collective action, financial sustainability, and possible competition with cannabis distribution via pharmacies that could diminish membership. In the case of Uruguay, UCCs are part of a regulation effort, though they may not be preferred over other legal alternatives already in place. Copyright © 2016 Elsevier B.V. All rights reserved.

2008-01-01

Lead, ubiquitous in the environment as a result of mining and industrialization, is found as a contaminant in humans although it has no known physiological function there. Lead-exposed children are known to be the population with the highest potential health risks. The recommended biomarker to assess environmental lead exposure in animals is lead level in blood. Before 2001, the Department of Toxicology and Environmental Hygiene was the only team to produce human monitoring data on Uruguayan populations (Manay 2001a,b; Mañay et al. 1999). Lead pollution in Uruguay first received official attention during the 2001 La Teja poisoning episode. It was in the La Teja neighbourhood of Montevideo that high BLL were found in children (as high as 20 microg/dL), prompting corrective responses from Health and Environmental authorities. Growing awareness of environmental lead pollution and consequential human health effects from that event, resulted in public debate and demands for solutions from Health and Environmental authorities. Citizens demanded public disclosure of information concerning lead pollution and wanted action to address contaminated Uruguayan sites. In response, the Ministry of Health assembled an interinstitutional multidisciplinary committee, with delegates from health, environmental, labor, educational, and social security authorities, as well as community nongovernmental organizations (NGOs), among others. The University of the Republic was designated to serve as the main responsible entity for technical advice and support. After 2001, new research on lead pollution was undertaken and included multidisciplinary studies with communities in response to health risk alerts. The main emphasis was placed on children exposed to environmental lead. Major sources of Uruguayan lead contamination, similar to those in other developing countries, result from metallurgical industries, lead-acid battery processing, lead wire and pipe factories, metal foundries, metal

2012-01-01

Background Stimulated by the WHO Framework Convention on Tobacco Control, many countries in Latin America adopted comprehensive smoke-free policies. In March 2006, Uruguay became the first Latin American country to adopt 100% smoke-free national legislation, which ended smoking in all indoor public places and workplaces, including restaurants and bars. The objective of this study was to evaluate trends in hospital admissions for cardiovascular disease 2 years before and 2 years after the policy was implemented in Uruguay. Methods Reports of hospital admissions for acute myocardial infarction (AMI) (International Classification of Disease-10 I21) from 37 hospitals (79% of all hospital admissions in the country), representing the period 2 years before and 2 years after the adoption of a nationwide smoke-free policy in Uruguay (between 1 March 2004 and 29 February 2008), were reviewed. A time series analysis was undertaken to compare the average monthly number of events of hospital admission for AMI before and after the smoke-free law. Results A total of 7949 hospital admissions for AMI were identified during the 4-year study period. Two years after the smoke-free policy was enacted, hospital admissions for AMI fell by 22%. The same pattern and roughly the same magnitude of reduction in AMI admissions were observed for patients seen in public and private hospitals, men, women and people aged 40–65 years and older than 65 years. Conclusions The national smoke-free policy implemented in Uruguay in 2006 was associated with a significant reduction in hospital admissions for AMI. PMID:22337557

The aim of this study was to analyze the evolution of the legal framework, health system of donation, and transplantation of cells, tissues, and organs, measured based on processes and rates from 1978 to 2008 in Uruguay. We analyzed 3 decades (1978-1988/1989-1998/1999-2008) by the following evaluation: the legislation, donation and transplantation system, procurement, registration of pre-state of voluntary donations, actual donations and transplantation rates of solid organs (kidneys, heart, liver, and pancreas), and rates of donation and transplantation of tissues (corneal and laminar [skin, amniotic membrane, and fascialata]), of cardiovascular elements (valves and vases), and of ostearticular tissues (bones and tendons). Uruguay has maintained continuous governmental politics in donation and transplantation. In the last decade the elaboration of a strategic plan by promoting Laws and Decrees of Encephalic Death, Presumed Donation and Security of Cells and Tissues, as well as the creation of the Unit Procurement, the registration of nonrelated donors for hematopoietic stem cells, and the re-engineering of tissue banking, has shown a significant increase in deceased donation and cadaveric transplantation, reaching the first highest overall donor rate in Latin America with 24/pmp multiorgan donors.

We aimed to estimate for the first time the burden of fungal infections in Uruguay. Data on population characteristics and underlying conditions were extracted from the National Statistics Institute, the World Bank, national registries, and published articles. When no data existed, risk populations were used to estimate frequencies extrapolating from the literature. Population structure (inhabitants): total 3,444,006; 73% adults; 35% women younger than 50 years. Size of populations at risk (total cases per year): HIV infected 12,000; acute myeloid leukemia 126; hematopoietic stem cell transplantation 30; solid organ transplants 134; COPD 272,006; asthma in adults 223,431; cystic fibrosis in adults 48; tuberculosis 613; lung cancer 1400. Annual incidence estimations per 100,000: invasive aspergillosis, 22.4; candidemia, 16.4; Candida peritonitis, 3.7; Pneumocystis jirovecii pneumonia, 1.62; cryptococcosis, 0.75; severe asthma with fungal sensitization, 217; allergic bronchopulmonary aspergillosis, 165; recurrent Candida vaginitis, 6323; oral candidiasis, 74.5; and esophageal candidiasis, 25.7. Although some under and overestimations could have been made, we expect that at least 127,525 people suffer from serious fungal infections each year. Sporothrichosis, histoplasmosis, paracoccidioidomycosis, and dermatophytosis are known to be frequent but no data are available to make accurate estimations. Given the magnitude of the burden of fungal infections in Uruguay, efforts should be made to improve surveillance, strengthen laboratory diagnosis, and warrant access to first line antifungals.

To examine social gradients in tobacco use in Argentina and Uruguay, using newly available directly comparable data sets. Secondary analysis of Global Adult Tobacco Survey data from Argentina (N=6645) and Uruguay (N=5581). Social gradients in current tobacco use, exposure to secondhand smoke, and cessation attempt were examined with sex-stratified and age-adjusted logistic regression. Among men, there is evidence of higher odds of being a current smoker among respondents with lower levels of education, but the association is only statistically significant for respondents with less than primary education in Uruguay (OR=2.15, 95% CI 1.22 to 3.77). Similarly, women with lower levels of education have higher odds of being a current smoker in Uruguay. The association between education and exposure to secondhand smoke is broadly similar for both sexes in both countries, with generally higher odds among groups with low education, though the relationship is only statistically significant among men in Uruguay (OR=1.77, 95% CI 1.08 to 2.92). In both countries, respondents with lower levels of education in general have higher odds of having attempted to quit smoking in the past year, although these associations did not attain statistical significance. Social gradients in tobacco use, exposure to secondhand smoke and cessation attempts are broadly similar in both countries. Efforts to evaluate the long-term effects of tobacco control efforts in these countries should monitor how policies affect national averages, and the social gradients that are embedded in aggregate data.

2017-01-01

To analyze the strategies developed by the health centers to implement the law of legal abortion (LA) in public services of the primary care in Montevideo, Uruguay. A qualitative research was conducted combining techniques of document analysis, self-administered questionnaires to key informants, and in-depth interviews with directors of health centers. A simple summative index of accessibility to abortion services was built. The law approved in Uruguay in 2012 demanded the development of a strategy to promote women's accessibility to LA in the public primary care system. The services failed to fully implement the strategy, due to institutional barriers. Despite the wide availability of LA services in primary care and that they are an integral part of sexual and reproductive health benefits, there is an important barrier to their use in the number of gynecologists that appeal to conscientious objection.

Uruguay, a country with one of the highest lung cancer rates worldwide, initiated a series of comprehensive anti-smoking measures in 2005. We assess the tobacco control policies in the context of cohort-driven lung cancer incidence trends over a 25-year period, providing baseline predictions to 2035. Using data from the National Cancer Registry of Uruguay, an age-period-cohort analysis of trends 1990-2014 was performed. The NORDPRED package was used to predict the annual number of new cases of lung cancer and incidence rates up to 2035. In men, age-standardised (world) rates declined from a peak of 165.6 in 1995 to 103.1 by 2014, translating to a 70% reduction in the risk of lung cancer in men born in 1970 relative to the early-1940s. In females, rates increased steadily from 18.3 in 1991 to 30.0 by 2014, with successive increases in risk among generations of women born 1940-1960. There is however evidence of a decline in observed rates in women born recently. Extrapolations of the trends indicate an 8% reduction in the mean number of new lung cancer cases in men by 2035, but a 69% increase in women. Despite observed and predicted reductions in lung cancer incidence in Uruguayan men, rates among women are set to continue to increase, with a large rise in the annual number of female lung cancer diagnoses expected before 2035. There are signals of a diminishing risk among recent generations of women born after 1960. The current analysis provides important baseline information in assessing the future impact of the recent tobacco control initiatives in Uruguay. Copyright © 2018 Elsevier Ltd. All rights reserved.

In 1828, between 8,000 and 15,000 Indians from the Jesuit Missions were brought to Uruguay. There, they were settled in a village, presently named Bella Unión, in the northwest corner of the country. According to historic sources, the Indians abandoned the settlement shortly thereafter, with the village subsequently repopulated by "criollos" and immigrants from abroad. As a first approach to reconstruct the genetic history of the population, data about the living population genetic structure will be used. Based on the analysis of the maternal lineages of the inhabitants of Bella Unión, and of those from two nearby villages, we expect to partially answer what happened with the first and subsequent inhabitants. We analyzed the maternal lineages of the present inhabitants of Bella Unión and neighboring localities through the sequencing of the mitochondrial DNA control region. A total of 64.3%, 5.7%, and 30% of the mtDNAs were of Native, African, and West Eurasian origin, respectively. These figures are quite similar to that of the population of Tacuarembó, which is located in northeastern Uruguay. The four main Native American founding haplogroups were detected, with B2 being the most frequent, while some rare subhaplogroups (B2h, C1b2, D1f1) were also found. When compared with other Native American sequences, near- matches most consistently pointed to an Amazonian Indian origin which, when considered with historical evidence, suggested a probable Guaraní-Missionary-related origin. The data support the existence of a relationship between the historic and present inhabitants of the extreme northwest Uruguay, with a strong contribution of Native Americans to the mitochondrial DNA diversity observed there. © 2014 Wiley Periodicals, Inc.

The freshwater cnidarian Craspedacusta sowerbii Lankester 1880, has invaded lakes and ponds as well as artificial water bodies throughout the world. The first record in Uruguay corresponding to the jellyfish was made in 1961 in two artificial fountains, with no mention of the polyp form. Although local reports of other related polyp species have been made, information on the benthic form of C. sowerbii is lacking. Here we report the finding of live frustules, solitary individuals, medusae and colonies from a natural lagoon in August 2010, allowing us to observe the morphology and behavior of the polyp stage in captivity. In addition, molecular identification and remarks on the potencial path of introduction are presented. This is the first record in Uruguay of both polyp and medusa stages of C. sowerbii in a natural water body, Del Medio Lagoon (Dpto. de Florida), Uruguay.

The purpose of this study was to analyze the evolution of donation and organ transplantation in Uruguay, after the initiation of a program of transplant coordination, which began in 2000. The total number of effective donors increased from 28.7 per million people (pmp) in 2000 to 48.1 pmp in 2005, which constituted an increase of 75%. The number of real donors also increased from 10 pmp in 2000 to 20.6 pmp in 2005, more than a 100% increase, with a cadaveric renal transplantation rate of 36 pmp (2005). The conversion of effective to real donors (RD/ED) increased from 0.125 to 0.42. Familial refusal decreased from 62.1% in 2000 to 19% in 2005, which constituted a decrease of 70%. We concluded that implementation of transplant coordinators and involvement of intensive care medical doctors in coordination have had a strong impact on these results.

Background Bladder cancer is the fourth most frequent malignancy among Uruguayan men. A previous study from Uruguay suggested a high risk of bladder cancer associated with maté drinking. We conducted an additional case-control study in order to further explore the role of non-alcoholic beverages in bladder carcinogenesis. Methods In the time period 1996–2000, 255 incident cases with transitional cell carcinoma of the bladder and 501 patients treated in the same hospitals and in the same time period were frequency matched on age, sex, and residence. Both cases and controls were face-to-face interviewed on occupation, tobacco smoking, alcohol drinking and intake of maté, coffee, tea, and soft drinks. Statistical analysis was carried out by unconditional multiple logistic regression. Results Ever maté drinking was positively associated with bladder cancer (odds ratio [OR] 2.2, 95% confidence interval [CI] 1.2–3.9) and the risk increased for increasing duration and amount of maté drinking. Both coffee and tea were strongly associated with bladder cancer risk (OR for coffee drinking 1.6, 95% CI 1.2–2.3; OR for tea drinking 2.3, 95% CI 1.5–3.4). These results were confirmed in a separate analysis of never-smokers. Conclusion Our results suggest that drinking of maté, coffee and tea may be risk factors for bladder carcinoma in Uruguay.

The ashes and dust resulting from the 2011 eruptions of the Puyehue volcano in Chile more than doubled monthly averages of PM10 concentrations in Montevideo, Uruguay. Few studies have taken advantage of natural experiments to assess the relationship between ambient air pollutant concentrations and birth outcomes. In this study we explored the effect of particulate matter with diameter of ≤ 10 μm (PM10) on perinatal outcomes in Uruguay, a middle-income country in South America with levels of PM10 that in general do not exceed the recommended thresholds. The analyzed outcomes are preterm birth, term birth weight, and term low birth weight. We took advantage of the sharp variation in PM10 concentrations due to the Puyehue eruptions to estimate the associations between mother's exposure to PM10 in each trimester of pregnancy and perinatal outcomes. We use birth registries for 2010-2013 and control for covariates, including maternal and pregnancy characteristics, weather, co-pollutants, and calendar quarter and hospital indicators. A 10-μg/m3 increase in exposure to PM10 during the third trimester was associated with a higher likelihood of a preterm birth [odds ratio (OR) = 1.10; 95% CI: 1.03, 1.19]. The association was robust to different model specifications, and increased with categorical exposure levels (OR for third-trimester PM10 ≥ 70 vs. < 30 μg/m3 = 5.24; 95% CI: 3.40, 8.08). Exposures were not consistently associated with birth weight or low birth weight among term births, though second-trimester exposures were associated with higher birth weight, contrary to expectations. Taking advantage of a natural experiment, we found evidence that exposure to high levels of PM10 during the third trimester of pregnancy may have increased preterm births among women in Montevideo, Uruguay.

Breast cancer (BC) shows very high incidence rates in Uruguayan women. The present factor analysis of ductal carcinoma of the breast, the most frequent histological type of this malignancy both in Uruguay and in the World, was conducted at a prepaid hospital of Montevideo, Uruguay. We identified 111 cases with ductal BC and 222 controls with normal mammograms. A factor analysis was conducted using 39 food groups, allowing retention of six factors analyzed through logistic regression in order to obtain odds ratios (OR) associated with ductal BC. The low fat and non-alcoholic beverage patterns were inversely associated (OR=0.30 and OR=0.45, respectively) with risk. Conversely, the fatty cheese pattern was positively associated (OR=4.17) as well as the fried white meat (OR=2.28) and Western patterns (OR 2.13). Ductal BC shared similar dietary risk patterns as those identified by studies not discriminating between histologic type of breast cancer.

Introduction The 5A’s (Ask, Advise, Assess, Assist, and Arrange) strategy, a best-practice approach for cessation counseling, has been widely implemented in high-income countries for pregnant women; however, no studies have evaluated implementation in middle-income countries. The study objectives were to assess smoking patterns and receipt of 5A’s among pregnant women in Buenos Aires, Argentina and Montevideo, Uruguay. Methods Data were collected through administered questionnaires to women at delivery hospitalizations during October 2011–May 2012. Eligible women attended one of 12 maternity hospitals or 21 associated prenatal care clinics. The questionnaire included demographic data, tobacco use/cessation behaviors, and receipt of the 5A’s. Self-reported cessation was verified with saliva cotinine. Results Overall, of 3400 pregnant women, 32.8% smoked at the beginning of pregnancy; 11.9% quit upon learning they were pregnant or later during pregnancy, and 20.9% smoked throughout pregnancy. Smoking prevalence varied by country with 16.1% and 26.7% who smoked throughout pregnancy in Argentina and Uruguay, respectively. Among pregnant smokers in Argentina, 23.8% reported that a provider asked them about smoking at more than one prenatal care visit; 18.5% were advised to quit; 5.3% were assessed for readiness to quit, 4.7% were provided assistance, and 0.7% reported follow-up was arranged. In Uruguay, those percentages were 36.3%, 27.9%, 5.4%, 5.6%, and 0.2%, respectively. Conclusions Approximately, one in six pregnant women smoked throughout pregnancy in Buenos Aires and one in four in Montevideo. However, a low percentage of smokers received any cessation assistance in both countries. Healthcare providers are not fully implementing the recommended 5A’s intervention to help pregnant women quit smoking. PMID:26117836

Smoke-free legislation eliminating tobacco smoke in all indoor public places and workplaces is the international standard to protect all people from exposure to secondhand smoke. Uruguay was the first country in the Americas and the first middle-income country in the world to enact a comprehensive smoke-free national legislation in March 2006. To compare air nicotine concentrations measured in indoor public places and workplaces in Montevideo, Uruguay before (November 2002) and after (July 2007) the implementation of the national legislation. Air nicotine concentrations were measured for 7-14 days using the same protocol in schools, a hospital, a local government building, an airport and restaurants and bars. A total of 100 and 103 nicotine samples were available in 2002 and 2007, respectively. Median (IQR) air nicotine concentrations in the study samples were 0.75 (0.2-1.54) microg/m(3) in 2002 compared to 0.07 (0.0-0.20) microg/m(3) in 2007. The overall nicotine reduction comparing locations sampled in 2007 to those sampled in 2002 was 91% (95% CI 85% to 94%) after adjustment for differences in room volume and ventilation. The greatest nicotine reduction was observed in schools (97% reduction), followed by the airport (94% reduction), the hospital (89% reduction), the local government building (86% reduction) and restaurants/bars (81% reduction). Exposure to secondhand smoke has decreased greatly in indoor public places and workplaces in Montevideo, Uruguay, after the implementation of a comprehensive national smoke-free legislation. These findings suggest that it is possible to successfully implement smoke-free legislations in low and middle-income countries.

The hepatitis A and E virus (HAV and HEV) share the fecal-oral mechanism. Hepatitis A is an endemo-epidemic disease in Uruguay but no data on the epidemiologic pattern of the HEV is available. The aims of this study were to update the epidemiologic behavior of the HAV in Montevideo and demonstrate the circulation of the HEV in Uruguay. Two hundred fourteen patients who consulted in the Policlínica de Nutrición y Digestivo were studied, 185 (86%) of whom were anti HAV (HAVAB, Abbot) positive. 81.8% (117/143) of those residents in Montevideo and 95.7% (68/71) of those who were from the inland were anti-HAV positive. From the Montevideo population 55.8% cases under the age of 40 years were anti-HAV positive and occurred in 97.6% of those older (p < 0.001). Considering the health care conditions of the positive patients in Montevideo, 95.6% (43/45) had septic chambers and 75.5% (74/98) disposed of toilet facilities (p < 0.001). It is concluded that although the global prevalence has been maintained since 1982, there is a change in the epidemiologic pattern with greater risk of infection in patients under the age of 40 years proceeding from areas without toilet facilities. The prevalence of total antibodies for HEV (EIA, Abbot) was 2.8% in this population. An association was observed with HAV in 2.2% (4/185). Moreover, a sample of 252 blood donors from the National Blood Service was analyzed with 5 being found to be anti HEV positive, with only 3 (1.2%) being confirmed in the Center for Disease Control in the United States. Although no definitive conclusions may be drawn from the present study, from an epidemiologic point of view, it has been shown that there is evidence of the circulation of HEV in Uruguay, in both the out patient and in blood donor populations.

Provenance and paleogeography of the Devonian Durazno Group, southern Parana Basin in Uruguay

A succession of Devonian cover rocks occurs in outcrop and in the subsurface of central-northern Uruguay where they were deposited in an intracratonic basin. This Durazno Group comprises three distinct stratigraphic units, namely the Cerrezuelo, Cordobés and La Paloma formations. The Durazno Group does not exceed 300 m of average thickness and preserves a transgressive-regressive cycle within a shallow-marine siliciclastic shelf platform, and is characterized by an assemblage of invertebrate fossils of Malvinokaffric affinity especially within the Lower Devonian Cordobés shales. The sedimentary provenance of the Durazno Group was determined using petrography, geochemistry, and morphological studies of detrital zircons as well as their U-Pb ages. Sandstone petrography of Cerrezuelo and La Paloma sequences shows that they have a dominantly quartz-feldspathic composition with a minor contribution of other minerals. Whole-rock geochemical data indicate that alteration was strong in each of the three formations studied; chondritic-normalized REE patterns essentially parallel to PAAS, the presence of a negative Eu-anomaly, and Th/Sc and La/Hf ratios point to an average source composition similar to UCC or slightly more felsic. Within the Cerrezuelo Formation, recycling of older volcano-metasedimentary sources is interpreted from Zr/Sc ratios and high Hf, Zr, and REE concentrations. U-Pb detrital zircon age populations of the Cerrezuelo and La Paloma formations indicate that the principal source terranes are of Neoproterozoic age, but include also minor populations derived from Mesoproterozoic and Archean-Paleoproterozoic rocks. A provenance from the Cuchilla Dionisio-Dom Feliciano, Nico Pérez and Piedra Alta terranes of Uruguay and southern Brazil is likely. This study establishes an intracratonic extensional tectonic setting during Durazno time. Considering provenance age sources, regional paleocurrent distributions and the established orogenic history recorded in SW

Comprehensive smoke-free laws have been followed by drops in hospitalisations for acute myocardial infarction (AMI), including in a study with 2 years follow-up for such a law in Uruguay. Multiple linear and negative binomial regressions for AMI admissions (ICD-10 code 121) from 37 hospitals for 2 years before and 4 years after Uruguay implemented a 100% nationwide smoke-free law. Based on 11 135 cases, there was a significant drop of -30.9 AMI admissions/month (95% CI -49.8 to -11.8, p=0.002) following implementation of the smoke-free law. The effect of the law did not increase or decrease over time following implementation (p=0.234). This drop represented a 17% drop in AMI admissions following the law (IRR=0.829, 95% CI 0.743 to 0.925, p=0.001). Adding two more years of follow-up data confirmed that Uruguay's smoke-free law was followed by a substantial and sustained reduction in AMI hospitalisations.

Uruguay exhibits one of the highest rates of breast cancer in Latin America, similar to those of developed nations, the reasons for which are not completely understood. In this study we investigated the effect that ancestral background has on breast cancer susceptibility among Uruguayan women. We carried out a case-control study of 328 (164 cases, 164 controls) women enrolled in public hospitals and private clinics across the country. We estimated ancestral proportions using a panel of nuclear and mitochondrial ancestry informative markers (AIMs) and tested their association with breast cancer risk. Nuclear individual ancestry in cases was (mean ± SD) 9.8 ± 7.6% African, 13.2 ± 10.2% Native American and 77.1 ± 13.1% European, and in controls 9.1 ± 7.5% African, 14.7 ± 11.2% Native American and 76.2 ± 14.2% European. There was no evidence of a difference in nuclear or mitochondrial ancestry between cases and controls. However, European mitochondrial haplogroup H was associated with breast cancer (OR = 2.0; 95% CI 1.1, 3.5). We have not found evidence that overall genetic ancestry differs between breast cancer patients and controls in Uruguay but we detected an association of the disease with a European mitochondrial lineage, which warrants further investigation.

The European wild boar Sus scrofa was first introduced into Uruguay, in southern South America during the early decades of the last century. Subsequently, and starting from founder populations, its range spread throughout the country and into the neighbouring Brazilian state Rio Grande do Sul. Due to the subsequent negative impact, it was officially declared a national pest. The main aim in the present study was to provide a more comprehensive scenario of wild boar differentiation in Uruguay, by using mtDNA markers to access the genetic characterization of populations at present undergoing rapid expansion. A high level of haplotype diversity, intermediate levels of nucleotide diversity and considerable population differentiation, were detected among sampled localities throughout major watercourses and catchment dams countrywide. Phylogenetic analysis revealed the existence of two different phylogroups, thereby reflecting two deliberate introduction events forming distantly genetic lineages in local wild boar populations. Our analysis lends support to the hypothesis that the invasive potential of populations emerge from introgressive hybridization with domestic pigs. On taking into account the appreciable differentiation and reduced migration between locales in wild boar populations, management strategies could be effective if each population were to be considered as a single management unit.

[Proposals for health reform and equity in Uruguay: a redefinition of the Welfare State?].

PubMed

Mitjavila, Myriam; Fernandez, José; Moreira, Constanza

2002-01-01

This article reviews and analyzes health sector reform proposals in Uruguay and the possible effects of such reforms in terms of equity, the health sector's institutional structure, and the power relationship between the various actors in the process. The authors contend that a highly structured yet simultaneously fragmented system has conspired against any attempt to introduce major reforms into the system. Thus the only possibility for reform resides neither in the consolidation of the so-called Institutions for Collective Medical Care (IAMCs) nor in the move towards a residual model. Rather, Uruguay is witnessing the system's passive restructuring (i.e., reform by default). In this context and given the system's built-in inequities, the current trend is towards an even more regressive distribution of goods and services. The authors use qualitative and quantitative techniques to show that inequities in expenditure, access, and quality have resulted from long-term developments and adaptive movements of an IAMC system in fiscal stress and the public system's declining quality. Thus, in the absence of changes in state policy that redefine the actors' power or in the absence of system collapse, the country should expect this same regressive trend to deepen.

Fusarium graminearum sensu stricto (F. graminearum s.s.) is the major causal agent of Fusarium head blight of wheat worldwide, and contaminates grains with trichothecene mycotoxins that cause serious threats to food safety and animal health. An important aspect of managing this pathogen and reducing mycotoxin contamination of wheat is knowledge regarding its population genetics. Therefore, isolates of F. graminearum s.s. from the major wheat-growing region of Uruguay were analyzed by amplified fragment length polymorphism assays, PCR genotyping, and chemical analysis of trichothecene production. Of the 102 isolates identified as having the 15-ADON genotype via PCR genotyping, all were DON producers, but only 41 strains were also 15-ADON producers, as determined by chemical analysis. The populations were genotypically diverse but genetically similar, with significant genetic exchange occurring between them. Analysis of molecular variance indicated that most of the genetic variability resulted from differences between isolates within populations. Multilocus linkage disequilibrium analysis suggested that the isolates had a panmictic population genetic structure and that there is significant recombination occurs in F. graminearum s.s. In conclusion, tour findings provide the first detailed description of the genetic structure and trichothecene production of populations of F. graminearum s.s. from Uruguay, and expands our understanding of the agroecology of F. graminearum and of the correlation between genotypes and trichothecene chemotypes.

The importance of XRD analysis in provenance and palaeoenvironmental studies of the Piedras de Afilar Formation, Neoproterozoic of Uruguay

The Piedras de Afilar Formation crops out in the southeast part of Uruguay, forming part of the Tandilia Terrane (sensu Bossi et al. 2005). Pamoukaghlian et al. (2006) and Gaucher et al. (2008) have published δ13C, δ18O and U/Pb SHRIMP results, which indicate a Neoproterozoic age for this formation. The palaeoenvironment has been defined as a shallow marine platform based on the presence of interference ripples, hummocky and mega-hummocky cross-stratification. X-ray diffraction (XRD) analyses help to better constrain the palaeoenvironment: the presence of chlorite/smectite found in black shales, suggest a reducing environment, and abundant illite indicates a cold to temperate climate. Provenance studies have been undertaken that utilise a combination of detailed palaeocurrent measurements, petrographic descriptions, XRD analyses, and geochemical isotopic analyses, including U/Pb SHRIMP determinations. Mineral compositional diagrams for sandstones suggest a stable cratonic provenance. Palaeocurrents are mainly from the NNE, indicating a provenance from the cratonic areas of the Tandilia Terrane. The illite crystal index indicates diagenetic to low-metamorphic conditions for the sequence; this is important to confirm that the identified minerals are authigenic. Clay minerals identified by XRD analysis of sandstones from the siliciclastic member are illite (80 - 90%), kaolinite (5 - 10%), and chlorite (5 - 10%). This is consistent with a provenance from the cratonic areas (quartz-feldspar dominated rock types). Isotopic analyses have been undertaken to provide better constraints on the tectonic setting. U/Pb SHRIMP ages for the youngest zircons are 990 Ma (Gaucher et al. 2008), and the basal granite (Granito de la Paz) is 2056 ± 11 Ma (Hartmann et al. 2001), suggesting a provenance from the Archaean basement for the Piedras de Afilar Formation, like its counterparts in the Rio de la Plata Craton.

Community-associated MRSA (CA-MRSA) strains have emerged in Uruguay. We reviewed Staphylococcus aureus isolates from a large healthcare facility in Montevideo (center A) and obtained information from 3 additional hospitals on patients infected with CA-MRSA. An infection was defined as healthcare-onset if the culture was obtained >48 hours after hospital admission. At center A, the proportion of S. aureus infections caused by CA-MRSA increased from 4% to 23% over 2 years; the proportion caused by healthcare-associated MRSA (HA-MRSA) decreased from 25% to 5%. Of 182 patients infected with CA-MRSA, 38 (21%) had healthcare-onset infections. Pulsed-field gel electrophoresis determined that 22 (92%) of 24 isolates were USA1100, a community strain. CA-MRSA has emerged in Uruguay and appears to have replaced HA-MRSA strains at 1 healthcare facility. In addition, CA-MRSA appears to cause healthcare-onset infections, a finding that emphasizes the need for infection control measures to prevent transmission within healthcare settings. PMID:18680644

The Isla Cristalina de Rivera crystalline complex in northeastern Uruguay underwent a multistage magmatic and metamorphic evolution. Based on SHRIMP U-Pb zircon, Th-U-Pb monazite (CHIME-EPMA method) and K-Ar age data from key units several events can be recognized: (1) multistage magmatism at 2,171-2,114 Ma, recorded on zircon of the granulitic orthogneisses and their 2,093-2,077 Ma overgrowths; (2) a distinct amphibolite facies metamorphism at ~1,980 Ma, recorded by monazite; (3) greenschist facies reworking and shearing at ca. 606 Ma (monazite and K-Ar on muscovite) along the Rivera Shear Zone, and finally (4) intrusion of the post-tectonic Sobresaliente and Las Flores granites at around 585 Ma. Lithological similarities, geographic proximity and coeval magmatic and metamorphic events indicate a similar tectonometamorphic evolution for the Isla Cristalina de Rivera, the Valentines Block in Uruguay and the Santa María Chico Granulitic Complex in southern Brazil, since at least 2.1 Ga.

Low-Temperature Thermochronology Investigation in Uruguay and Southernmost Brazil: Apatite (U-Th)/He Results

2017-12-01

Low-temperature thermochronology has successfully allowed one to reveal exhumation histories of many orogenic belts across the Earth, and lately these techniques have been applied in cratonic regions. The present study aims to constrain thermal history and exhumation of the South Atlantic Passive Margin, between Uruguay and Southernmost Brazil, a region scarce of thermochronological data. This location has become relatively stable after the Neoproterozoic Brasiliano Orogeny, being more intensely disturbed by tectonics during the Gondwana Breakup and consequent opening of the Atlantic Ocean (Jurassic - Cretaceous). Both apatite and zircon (U-Th)/He methods are being applied on basement rocks, and since those have a long cooling history, radiation damage is expected to play an important role in crystal ages. A total of 25 samples were analyzed, and preliminary apatite (U-Th)/He results reveals unweighted sample ages ranging from Permian to Lower-Cretaceous in Southernmost Brazil, with a couple of outliers with Devonian - Carboniferous ages. In Uruguay results can be grouped in two different clusters: one of samples with Jurassic to Lower-Cretaceous ages, and another of Devonian to Permian ages. This wide range of results can be assign to variations in the uranium content of the grains, due the presence of inclusions, compositional zonation or substantial radiation damage of the crystalline lattice. In most cases, ages tend to increase with crystal eU content. No clear relationship between ages and tectonic terranes has been found so far, neither between ages and elevation, since the region does not have significant topographic variations. Younger ages are commonly found closer to the coastal region, possibly in response to the rift shoulders uplift during Gondwana breakup and further exhumation and denudation at higher rates. An anomalous concentration of older ages in the southern region of the Pelotas Batholith, close to the Brazil - Uruguay border, suggests a

Implementation of smokefree laws is followed by drops in hospital admissions for cardiovascular diseases and asthma. The impact of smokefree laws on use of non-hospital medical services has not been assessed. The purpose of this study is to evaluate the impact of Uruguay's national 100% smokefree legislation on non-hospital emergency care visits, hospitalizations for bronchospasm, and bronchodilator use. The monthly number of non-hospital emergency care visits and hospitalizations for bronchospasm, as well as monthly puffs of bronchodilators (total and per person), from 3 years prior to the adoption of the 100% smokefree policy on March 1, 2006, through 5 years after the policy were assessed using interrupted time series negative binomial regression. Data analysis was conducted in 2014. The incidence of non-hospital emergency visits for bronchospasm decreased by 15% (incidence rate ratio [IRR]=0.85, 95% CI=0.76, 0.94) following implementation of the law. Hospitalizations for bronchospasm did not change significantly (IRR=0.89, 95% CI=0.66, 1.21). Total monthly puffs of salbutamol and ipratropium administered in the non-hospital emergency setting decreased by 224 (95% CI=-372, -76) and 179 (95% CI=-340, -18.6), respectively, from means of 1,222 and 1,007 before the law. Uruguay's 100% smokefree law was followed by fewer emergency visits for bronchospasm and less need for treatment, supporting adoption of such policies in low- and middle-income countries to reduce the disease burden and healthcare costs associated with smoking.

Laboratorio Tecnológico del Uruguay (LATU) is the National Metrology Institute of Uruguay and has the obligation to maintain the national standards stated by National Law 15298. At present LATU is acting as a secondary laboratory as well as a primary laboratory. LATU was ISO 17025:2005 DKD (Deutscher Kalibrierdienst) accredited from 2001 up to 2007. By that time LATU decided to support its Capabilities of Measurement and Calibration (CMCs) at CIPM-MRA (Mutual Recognition Arrangement between national metrology institutes (NMIs)) by peer assessment. A Peer Review has been done in 2008 in order to get the QSTF (Sistema Interamericano de Metrología, Quality System Task Force) approval. "New "CMCs for Industrial Thermometers have been approved by the JCRB on September 2010. CMCs claimed for Standard Resistance Platinum Thermometers (SPRTs) calibration at fixed points have not been approved yet because there were some requirements of traceability of employed cells that were not fulfilled but will be solved properly. The declared CMCs have been chosen by LATU in order to cover the increasing calibration services required by the industry and the secondary calibration laboratories. To demonstrate its technical competence an support its declared "CMCs" LATU has also participated at bilateral and regional comparisons. In recent years LATU, the National Accreditation Body (OUA), the Standards Institute, the National Institute of Quality and Compliance Bodies have become Members of a new Institution to strengthen the Quality Infrastructure of the country (SUNAMEC). As part of this new activities, LATU is giving training courses to the secondary laboratories performing calibrations in temperature that want to get accredited by the National Accreditation Body and to act as Technical Evaluators or Auditors when required by OUA. It is expected, that in the future and in the frame of new accredited and recognized temperature calibration laboratories, LATU could strengthen its

In Uruguay, groundwater is frequently used for agricultural activities, as well as for human consumption in urban and rural areas. As in many countries worldwide, drinking water microbiological quality is evaluated only according to bacteriological standards and virological analyses are not mentioned in the legislation. In this work, the incidence of human viral (Rotavirus A, Norovirus GII, and human Adenovirus) and bacterial (total and thermotolerant coliform and Pseudomonas aeruginosa) contamination in groundwater in the Salto district, Uruguay, as well as the possible correlation between these groups of microorganisms, was studied. From a total of 134 groundwater samples, 42 (32.1%) were positive for Rotavirus, only 1 (0.7%) for both Rotavirus and Adenovirus, and 96 (72.6%) samples were positive for bacterial indicators. Results also show that Rotavirus presence was not associated with changes in chemical composition of the aquifer water. Bacteriological indicators were not adequate to predict the presence of viruses in individual groundwater samples (well scale), but a deeper spatial-temporal analysis showed that they are promising candidates to assess the viral contamination degree at aquifer scale, since from the number of wells with bacterial contamination the number of wells with viral contamination could be estimated.

Fusarium and Aspergillus mycotoxins contaminating wheat silage for dairy cattle feeding in Uruguay.

PubMed

Del Palacio, Agustina; Bettucci, Lina; Pan, Dinorah

Wheat is one of the most important cultivated cereals in Uruguay for human consumption; however, when harvest yields are low, wheat is usually used in ensiling for animal feeding. Ensiling is a forage preservation method that allows for storage during extended periods of time while maintaining nutritional values comparable to fresh pastures. Silage is vulnerable to contamination by spoilage molds and mycotoxins because ensilage materials are excellent substrates for fungal growth. The aim of the study was to identify the mycobiota composition and occurrence of aflatoxins and DON from wheat silage. A total of 220 samples of wheat were collected from four farms in the southwest region of Uruguay were silage practices are developed. The main fungi isolated were Fusarium (43%) and Aspergillus (36%), with Fusarium graminearum sensu lato and Aspergillus section Flavi being the most prevalent species. Aflatoxin concentrations in silo bags ranged from 6.1 to 23.3μg/kg, whereas DON levels ranged between 3000μg/kg and 12,400μg/kg. When evaluating aflatoxigenic capacity, 27.5% of Aspergillus section Flavi strains produced AFB1, 5% AFB2, 10% AFG1 and 17.5% AFG2. All isolates of F. graminearum sensu lato produced DON and 15-AcDON. The results from this study contribute to the knowledge of mycobiota and mycotoxins present in wheat silage.

Elevated blood lead levels (BPbs) have been identified in Uruguayan children in the La Teja neighborhood of Montevideo, but the extent of lead exposure in other city areas is unknown. Sources and predictors of exposure also remain understudied in this population. In 2007, the authors screened lead and hemoglobin levels in capillary blood of 222 preschool children from several areas of Montevideo, Uruguay, and identified predictors of elevated BPbs. Mean BPb was 9.0 +/- 6.0 microg/dL and 32.9% of children had levels >or= 10microg/dL. Mean hemoglobin level was 10.5 +/- 1.5 g/dL, with 44.1% having levels <10.5g/dL. Older child age, hemoglobin <10.5g/dL, and putting fingers/toys in the mouth were associated with higher BPbs. Young maternal age, less education, father's job with potential risk of lead exposure, and fewer family possessions were also associated with higher BPbs. Pediatric lead exposure is a public health problem in Uruguay, with children experiencing elevated BPbs at a young age.

This is a case study of a program to address professionalism at the Universidad de la República in Uruguay. We describe a five-year ongoing international collaboration. Relevant characteristics of the context, the program components, activities, and results were analyzed. The expected outcomes were to introduce standards of professional practices in the curricula of medical students and residents and the implementation of a program that might lead to a significant change in the culture of medicine in the University. Traditional didactics, interactive theater, and professional development workshops, issues such as teamwork and communication, professional behavior, and the culture of medicine, and physician wellness were addressed. A total of 359 faculty members, general practitioners, stakeholders, and other healthcare professionals (nurses, psychologists, social workers) participated in the intervention. The process led to specific achievements including new content in the curricula, the use of educational innovations to address issues of professionalism, a growing institutional culture of accountability, and the establishment of new rules and regulations. The strategies and interventions followed in the case of Uruguay can serve as a model to other developing countries to promote physician professionalism, wellness, and joy.

A disease named locally as churrío or churrido equino (i.e., equine scours) has occurred for at least 100 years in Uruguay and southern Brazil in farms along both shores of the Merín lake. This report describes cases of churrido equino and provides serologic, pathologic, and DNA-based evidence indicating that the disease is in fact equine monocytic ehrlichiosis (Potomac horse fever). Results of an epidemiological investigation conducted on an endemic farm are also presented. Clinical signs in 12 horses were fever, depression, diarrhea, dehydration, and sometimes colic and distal hind limb edema. Postmortem findings of 3 horses were of acute enterocolitis. Inclusion bodies containing ehrlichial organisms were found in the cytoplasm of macrophages of the large colon of 1 horse. Eleven of the 12 horses were serologically positive to Ehrlichia risticii (indirect fluorescent antibody assay) and, of 3 paired samples, 2 showed seroconversion. Ehrlichia risticii DNA was identified by a nested polymerase chain reaction in peripheral blood of an affected horse. A healthy horse inoculated with peripheral blood from an affected horse developed the disease and antibodies to E. risticii. The disease had a peak incidence in March (summer) and was statistically associated with a marshy ecosystem near the Merín lake, where large numbers of Pomacea spp. (Ampullariidae) snails were found. Incidence density was almost 8 times higher in nonnative horses than in native horses. It was concluded that the previous diarrheic disease of horses known in Uruguay and southern Brazil as churrido equino is equine monocytic ehrlichiosis.

To determine the factor structure of the Latin American & Caribbean Household Food Security Scale (ELCSA) and to study the influence of sociodemographic characteristics on each of the identified dimensions in Montevideo, Uruguay. Cross-sectional survey with a representative sample of urban households. Household food insecurity was measured using the ELCSA. The percentage of respondents who gave affirmative responses for each of the items of the ELCSA was determined. Exploratory factor analysis was carried out to determine the ELCSA's factor structure. A probit model was used to determine the impact of some individual and household sociodemographic characteristics on the identified dimensions of food insecurity. Metropolitan area centred on Montevideo, the capital city of Uruguay, April-September 2014. Adults aged between 18 and 93 years (n 742). The percentage of affirmative responses to the items of the ELCSA ranged from 4·4 to 31·7 %. Two factors were identified in the exploratory factor analysis performed on data from households without children under 18 years old, whereas three factors were identified for households with children. The identified factors were associated with different severity levels of food insecurity. Likelihood of experiencing different levels of food insecurity was affected by individual characteristics of the respondent as well as characteristics of the household. The influence of sociodemographic variables varied among the ELCSA dimensions. Household income had the largest influence on all dimensions, which indicates a strong relationship between income and food insecurity.

Glyphosate-resistant soybean cultivation is expanding rapidly in Uruguay, with its land area having increased by 95 times during the past 10 years. Because of the region's Neotropical conditions, insecticide use is required to ensure adequate soybean productivity. However, in areas shared by soybean crops and beekeepers - such as the southwestern zone of Uruguay (SWZU) - the use of insecticides can increase the risks of honeybee death and honey contamination. Uruguayan commercial and legal guidelines set out practices and field doses designed to prevent acute intoxication with insecticides. However, honeybees in the SWZU are predominantly a polyhybrid subspecies different from that used to set international reference values, and hence they may have a different acute toxicity response, thus rendering such precautions ineffective. The aim of this work was to assess the acute toxicity response of polyhybrid honeybees in the SWZU to cypermethrin (commercial formulation: Cipermetrina 25 Agrin®), chlorpyrifos (commercial formulation: Lorsban 48E®), and endosulfan (commercial formulation: Thionex 35®). Acute toxicity bioassays were conducted to determine the median lethal dose (LD(50)) of each insecticide for the honeybees. The results indicate that, compared with EU reference values, SWZU honeybees have a higher toxicological sensitivity to chlorpyrifos and endosulfan, and a lower toxicological sensitivity to cypermethrin, based on the commercial formulations tested. However, when these results were adjusted according to their field dose equivalents, only chlorpyrifos emerged as a potential problem for beekeeping, as the maximum recommended field dose of Lorsban 48E® for soybean crops in Uruguay is 23 times the corresponding LD(50) for honeybees in the SWZU.

Barbecued meat, salted meat and fried eggs were associated with significant increased risks of bladder cancer (odds ratio (OR) for high intake of salted meat 4.04, 95% confidence interval (CI) 2.24-7.27). On the other hand, all fruits, cooked vegetables, potatoes and cheese were associated with inverse associations (OR for high consumption of potatoes 0.38, 95% CI 0.23-0.64). The associations with salted and barbecued meat suggest that the way of preserving or cooking meat play a role in bladder carcinogenesis. More precisely, N-nitroso compounds and heterocyclic amines could be involved in this process.

Escherichia coli is one of the main etiological agents of neonatal calf diarrhea (NCD). The objective of this study was to assess the presence of virulence genes, genetic diversity, and antibiotic resistance mechanisms in E. coli associated with NCD in Uruguay. PCR was used to assess the presence of intimin, Shiga-like toxin, and stable and labile enterotoxin genes. Resistance to fluoroquinolones and oxyimino-cephalosporins was estimated on Müller-Hinton agar plates. Further antibiotic disc-diffusion tests were performed to assess bacterial multi-resistance. The presence of PMQR, ESBL, MCR-1, and integron genes was evaluated. Isolates were typed using ERIC-PCR, and 20 were selected for MLST, adhesion to Hep-2 cells, in vitro biofilm formation, and eukaryotic cytotoxicity. The prevalence of ETEC genes was lower than 3% in each case (estA and elt). Six isolates were EPEC (eae+) and 2 were EHEC/STEC (eae+/stx1+). The results of a diversity analysis showed high genetic heterogenicity among isolates. Additionally, different sequence types, including ST10, ST21, and ST69, were assigned to selected isolates. Thirty-six percent (96/264) of the isolates were fluoroquinolone-resistant, with 61/96 (63.5%) being multidrug-resistant. Additionally, 6 were oxyimino-cephalosporin-resistant. The qnrB, qnrS1, and bla CTX-M-14 genes were detected, whereas no isolates carried the mcr-1 gene. Isolates had the ability to adhere to Hep-2 cells and form biofilms. Only 1 isolate expressed toxins in vitro. E. coli from NCD cases in Uruguay are very diverse, potentially virulent, and may interact with eukaryotic cells. Zoonotic potential, together with resistance traits and the presence of horizontal transfer mechanisms, may play a significant role in infections caused by these microorganisms.

Climate is changing towards more extreme conditions all over the world. At the same time, land use is becoming more intensive worldwide and particularly in many developing countries, whereas several developed countries are trying to reduce the impacts of intensive agricultural production and lower the excessive nutrient loading and eutrophication symptoms in water bodies. In 2009, we initiated a comparative research project between the subtropical region (Uruguay) and the temperate region (Denmark) to compare the hydrology and nutrient fluxes in paired micro-catchments with extensive production or intensive agriculture. The four selected streams drained catchments of similar size (7 to 19 km2). We have established similarly equipped monitoring stations in the four micro-catchments in spring (November 2009, Uruguay; March 2010, Denmark) to monitor the effects of land use and agriculture intensity on stream hydrology and nutrient concentrations and fluxes under different climate conditions. We have conducted high frequency measurements in the four lowland streams with underwater probes (turbidity, pH, conductivity and oxygen measured every 15 minutes), fortnight grab sampling of water and automatic sampling of composite water samples for nutrient analysis (total and dissolved nitrogen and phosphorus; sampled every four hours and accumulated fortnightly). Moreover, water level and meteorological information (precipitation, air temperature, global radiation, humidity) has been recorded every 10 minutes and instantaneous flow measurements have been conducted at regular intervals, to facilitate the calculation of instantaneous discharge from continuous records of water level (stage-discharge relationships). We will show results of ca. 2 years from this comparative study between Uruguay and Denmark, and the importance of differences in climate and land use will be discussed.

Research is being pointed out as a path to nursing recognition. The knowledge production concerning the tendencies of research lines in nursing during the 90's, in Argentina, Chile, Paraguay and Uruguay, took part of a study that had the purpose to know the impact of the nursing profession practice on health in Latin America and in the Caribbean Islands. The methodology used was the exploratory quantitative research, and the database used were Lilacs and Medline. The most frequent investigation themes refer to nursing profession (up to 13.2%). Regarding the lines of investigation in nursing, we found out that the nursing professional stood out with 41%, being technique and methodology the main approaches. Chile was the country that produced the largest amount of research, 86.8% of the summaries. Referring to the financing source, no reference is made in 86.8% of the summaries. With reference to the number of authors involved with the published literature, 50.7% of the literature have only one author. The nurses should be aware to invest in the enlargement of this production.

Background Comprehensive smoke-free laws have been followed by drops in hospitalisations for acute myocardial infarction (AMI), including in a study with 2 years follow-up for such a law in Uruguay. Methods Multiple linear and negative binomial regressions for AMI admissions (ICD-10 code 121) from 37 hospitals for 2 years before and 4 years after Uruguay implemented a 100% nationwide smoke-free law. Results Based on 11 135 cases, there was a significant drop of −30.9 AMI admissions/month (95% CI −49.8 to −11.8, p=0.002) following implementation of the smoke-free law. The effect of the law did not increase or decrease over time following implementation (p=0.234). This drop represented a 17% drop in AMI admissions following the law (IRR=0.829, 95% CI 0.743 to 0.925, p=0.001). Conclusions Adding two more years of follow-up data confirmed that Uruguay’s smoke-free law was followed by a substantial and sustained reduction in AMI hospitalisations. PMID:25324157

Classic Human Astrovirus (Classic HAstV) are one of the most important causes of pediatric acute gastroenteritis (AGE), after rotaviruses and arguably caliciviruses. The aim of this study was to determine the molecular epidemiology of Classic HAstV from 175 clinical samples, being 153 stools and 22 vomits, collected from pediatric hospitalized patients with AGE in Salto city, Uruguay, from January 2011 to December 2012. Classic HAstV were detected and genotyped by using a qualitative Retro Transcription-Polimerase Chain Reaction (RT-PCR) directed to the Open Reading Frame-2 (ORF2) region C. Amplicons were sequenced and phylogenetic analyses were carried out in order to determine genotypes and lineages. Classic HAstV were detected in 18 out of 175 analyzed samples (10.3%) and 14 of them (78.0%) were successfully sequenced being 6 (42.8%) classified as HAstV-1 (1a lineage), 4 (28.6%) as HAstV-2 (2c lineage), and 4 (28.6%) as HAstV-3 (3c lineage). A higher detection of Classic HAstV infections was observed in autumn for both years of surveillance, and the majority of the positive cases were observed in 2011. The group of children between 2 and 5 years old presented the higher percentage of infections. To our knowledge, the present study represents the first report of astrovirus from acute gastroenteritis cases in Uruguay, evidencing its role as a relevant etiologic agent in severe cases of this disease. © 2017 Wiley Periodicals, Inc.

Ochratoxin A (OTA) is a nephrotoxic mycotoxin which has been found worldwide as a contaminant in wines. It is produced on grapes mainly by molds from Aspergillus section Nigri. This study has demonstrated for the first time the occurrence of black aspergilli on Tannat grapes from Uruguay, in a two year survey. Aspergillus uvarum (uniseriate) and Aspergillus welwitschiae (from Aspergillusniger aggregate) were the prevalent species whereas Aspergillus carbonarius which is considered the main OTA producing species was not detected. OTA production in culture medium was evaluated for native isolates from A. niger aggregate and compared to levels produced by a type strain of A. carbonarius. This work also includes the development of quick and easy molecular methods to identify black aspergilli to species level, avoiding sequencing. Copyright © 2015 Elsevier B.V. All rights reserved.

We present in this work the development of astronomy in Uruguay since the colony times up to the present, stressing in particular those aspects related to the formal as well as informal teaching of astronomy. The first antecedents of astronomical studies in our country go back to the beginnings of the XVIIIth century related to the scientific expeditions from Europe coming to our shores. The teaching of astronomy was generalized at the high school level as soon as the end of the XIXth century, while itsintroduction at the university level happened much later, around the middle of the last century. We analyze the current situation of this subject, its problems, and some measures to strengthen its development.

The study aimed to measure the scientific production in Ophthalmology and Vision (O&V) in Argentina, Brazil, Chile, Paraguay and Uruguay over a period of 10 years (1995-2004), in order to find out temporal evolution and variations in this field of research. PubMed / Medline was used to retrieve records on O&V research literature. The search strategy included keywords, country in the affiliation field and publication date. Data were extracted from each citation and recorded in a spreadsheet. Subsequent analysis focused on type and main topic of publication, journals where articles had been published, and evolution of research done on animals and humans. A total of 1,216 citations were retrieved. Brazil had the largest number of authored publications with an average annual production of 82.4, followed by Argentina with 31.0, Chile 6.4, Uruguay 1.6, and Paraguay 0.2. The ratio of articles on O&V relative to publications involving Health Science ranged from 1.0 to 2.3. The frequency of publications almost tripled from 1995 to 2004. Research on humans showed a significant increase in Argentina and Brazil. Results provide initial benchmarks on O&V publication rates in countries in South America that may be useful to follow research trends.

Cannabis consumption patterns among frequent consumers in Uruguay.

PubMed

Boidi, María Fernanda; Queirolo, Rosario; Cruz, José Miguel

2016-08-01

In 2013, Uruguay became the first country to fully regulate the cannabis market, which now operates under state control. Cannabis can be legally acquired in three ways: growing it for personal use (self-cultivation), cannabis club membership, and from pharmacies (not yet implemented). Users must be entered into a confidential official registry to gain access. This article presents findings of a Respondent Driven Sample survey of 294 high-frequency cannabis consumers in the Montevideo metropolitan area. Frequent consumers resort to more than one method for acquiring cannabis, with illegal means still predominating after 1 year of the new regulation law. Cannabis users overwhelmingly support the current regulation, but many of them are reluctant to register. Some of the attitudes and behaviors of the high-frequency consumers pose a challenge to the success of the cannabis law. Individuals relying on more than one method of access defy the single access clause, a prerequisite for legal use, while the maximum amount of cannabis individuals can access monthly seems too high even for most frequent consumers, which might promote the emergence of a grey market. Reluctance to register among a significant proportion of high-frequency consumers raises doubts about the law's ability to achieve its stated objectives. Copyright © 2016 Elsevier B.V.

[Fiscal policy, affordability and cross effects in the demand for tobacco products: the case of Uruguay].

PubMed

Carbajales, Alejandro Ramos; Curti, Dardo

2010-01-01

Uruguay, a country with a solid tobacco control policy since 2005 shows, contrary to expectations, an insignificant decrease in total tobacco products' sales in the last five years. The hypothesis is that on one side, changes in household income and the income elasticity of the demand for cigarettes were important countervailing factors in the demand of both products. The period 2005-2009 shows a large increase of 36% in household real income in Uruguay due to fast economic recovery after the 2002 crisis. The second factor is the interchangeability of roll your own and cigarettes and the impact on the demand of each product as a reaction to tax and price changes. The tax and price of roll your own tobacco remains substantially lower than that of cigarettes. This fact, and the increased substitution of roll your own for cigarettes seems to be the main reasons for the low impact of the policy of tobacco tax and price increases. This paper then consists of a revision of a 2004 study to estimate separate demands for both main tobacco products and obtain estimates for own price, cross price and income elasticities. Then, a simulation study was performed using the elasticities found and two scenarios of increases in household income: moderate (2.5% per year) and high (5% per year) confirming that countries where income is growing fast and with a potential for substitution towards cheaper products require substantial cigarette tax and price increases for a fiscal tobacco control policy to become effective.

Cystic echinococcal lesions surgically removed from 99 patients aged 1-15 years in Uruguay were histopathologically studied. The lesions were collected from the lungs, liver, peritoneum, omentum, pleura, ovary, appendix and perinephrium. All intact cysts were well-developed and unilocular. Pulmonary and hepatic fertile cysts in which protoscoleces were produced were in 75% and 47%, respectively, of all patients. Fertile cysts having many protoscoleces were in the lungs of a 1-year-old infant. Sixteen ruptured pulmonary cysts were found in the lungs of 13 patients and four ruptured hepatic cysts were found in the liver of three patients. Pulmonary complications were seen in patients having pulmonary echinococcal cysts. In lung tissue surrounding echinococcal cysts, pulmonary complications included chronic congestion, hemorrhage, bronchopneumonia, as well as interstitial pneumonia that included histological changes caused by bronchiolitis, organizing pneumonia and obstructive pneumonia. Liver tissue adjacent to echinococcal cysts showed atrophy of hepatic cells, proliferation of interstices, small focal hemorrhages, and infiltration of mononuclear cells. The present study shows that a close relationship exists between pulmonary echinococcosis and pneumonia. The term 'echinococcal pneumonia' is proposed for pneumonia accompanying pulmonary echinococcosis.

The Global Threat Reduction Initiative's (GTRI) Offsite Source Recovery Project (OSRP) began recovering excess and unwanted radioactive sealed sources (sources) in 1999. As of February 2012, the project had recovered over 30,000 sources totaling over 820,000 Ci. OSRP grew out of early efforts at Los Alamos National Laboratory (LANL) to recover disused excess Plutonium- 239 (Pu-239) sources that were distributed in the 1960's and 1970's under the Atoms for Peace Program. Source recovery was initially considered a waste management activity. However, after the 9/11 terrorist attacks, the interagency community began to recognize that excess and unwanted radioactive sealed sources posemore » a national security threat, particularly those that lack a disposition path. After OSRP's transfer to the U.S. National Nuclear Security Administration (NNSA) to be part of GTRI, its mission was expanded to include all disused sealed sources that might require national security consideration. Recognizing the transnational threat posed by porous borders and the ubiquitous nature of sources, GTRI/OSRP repatriates U.S. origin sources based on threat reduction prioritization criteria. For example, several recent challenging source repatriation missions have been conducted by GTRI/OSRP in South America. These include the repatriation of a significant amount of Cs-137 and other isotopes from Brazil; re-packaging of conditioned Ra-226 sources in Ecuador for future repatriation; and, multilateral cooperation in the consolidation and export of Canadian, US, and Indian Co-60/Cs-137 sources from Uruguay. In addition, cooperation with regulators and private source owners in other countries presents opportunities for GTRI/OSRP to exchange best practices for managing disused sources. These positive experiences often result in long-term cooperation and information sharing with key foreign counterparts. International source recovery operations are essential to the preservation of U.S. national

The influence of insecticides commonly used for agricultural purposes on beehive depopulation in Uruguay was investigated. Honeycombs, bees, honey and propolis from depopulated hives were analyzed for pesticide residues, whereas from active beehives only honey and propolis were evaluated. A total of 37 samples were analyzed, representing 14,800 beehives. In depopulated beehives only imidacloprid and fipronil were detected and in active beehives endosulfan, coumaphos, cypermethrin, ethion and chlorpyrifos were found. Coumaphos was present in the highest concentrations, around 1,000 μg/kg, in all the propolis samples from active beehives. Regarding depopulated beehives, the mean levels of imidacloprid found in honeycomb (377 μg/kg, Standard Deviation: 118) and propolis (60 μg/kg, Standard Deviation: 57) are higher than those described to produce bee disorientation and fipronil levels detected in bees (150 and 170 μg/kg) are toxic per se. The other insecticides found can affect the global fitness of the bees causing weakness and a decrease in their overall productivity. These preliminary results suggest that bees exposed to pesticides or its residues can lead them in different ways to the beehive.

Legalizing a market for cannabis for pleasure: Colorado, Washington, Uruguay and beyond.

Room, Robin

2014-03-01

Colorado, Washington state and Uruguay are currently designing legal non-medical markets for cannabis. These clearly contravene the 1961 and 1988 drug conventions; options for what may happen next are discussed. The current provisions in the three regulatory schemes are summarized. From a public health perspective, the emphasis should be on holding down consumption with regulatory measures, but the public health agenda does not seem to be a strong consideration in the implementation of the US schemes, and they are paying little attention to what can be learned from the history of alcohol and tobacco regulation. While alternative paths to a cannabis market under the conventions are noted, the legalization initiatives underline the need to revise the drug conventions, making prohibition of domestic markets an optional matter. Such changes would also ease the path for including alcohol under the conventions, which would be an important step forward in global health. © 2013 Society for the Study of Addiction.

Triunfo, Patricia; Harris, Jeffrey; Balsa, Ana

2016-10-01

In 2005, shortly after ratifying the Framework Convention on Tobacco Control (FCTC), Uruguay began an ambitious tobacco control campaign that brought the country to the global forefront in the fight against smoking. The wide range of measures implemented in a relatively short period and the rigorousness with which policies were implemented and enforced have few precedents, even in the most developed countries. This paper presents a synthesis and update of several papers by the authors that evaluate different aspects of the campaign ten years following ratification of the FCTC. In particular, these research studies highlight the campaign's aggregate impact on the drop in prevalence of current tobacco consumption in adult and youth populations, and on decisions by pregnant women to quit smoking (1, 2), as well as the relative impact of tax policies in relation to non-price tobacco control measures. The analyses are based on observational studies (at the population or individual level) that use external (Argentina and Chile) and internal (nonsmokers) control groups. Pending challenges in the design of antismoking policies are also discussed.

Report of a large depletion in the ozone layer over southern Brazil and Uruguay by using multi-instrumental data

Ozone is one of the chemical compounds that form part of the atmosphere. It plays a key role in the stratosphere where the ozone layer is located and absorbs large amounts of ultraviolet radiation. However, during austral spring (August-November), there is a massive destruction of the ozone layer, which is known as the Antarctic ozone hole. This phenomenon decreases ozone concentration in that region, which may affect other regions in addition to the polar one. This anomaly may also reach mid-latitudes; hence, it is called the secondary effect of the Antarctic ozone hole. Therefore, this study aims to identify the passage of an ozone secondary effect (OSE) event in the region of the city of Santa Maria - RS (29.68° S, 53.80° W) by means of a multi-instrumental analysis using the satellites TIMED/SABER, AURA/MLS, and OMI-ERS. Measurements were made in São Martinho da Serra/RS - Brazil (29.53° S, 53.85° W) using a sounding balloon and a Brewer Spectrophotometer. In addition, the present study aims to describe and analyse the influence that this stratospheric ozone reduction has on temperatures presented by these instruments, including data collected through the radio occultation technique. The event was first identified by the AURA/MLS satellite on 19 October 2016 over Uruguay. This reduction in ozone concentration was found by comparing the climatology for the years 1996-1998 for the state of Rio Grande do Sul, which is close to Uruguay. This event was already observed in Santa Maria/RS-Brazil on 20 October 2016 as presented by the OMI-ERS satellite and the Brewer Spectrophotometer. Moreover, a significant decrease was reported by the TIMED/SABER satellite in Uruguay. On 21 October, the poor ozone air mass was still over the region of interest, according to the OMI-ERS satellite, data from the sounding balloon launched in Santa Maria/RS-Brazil, and measurements made by the AURA/MLS satellite. Furthermore, the influence of ozone on the

Meiobenthic communities in permanently open estuaries and open/closed coastal lagoons of Uruguay (Atlantic coast of South America)

2015-09-01

This study aimed to determine if estuarine meiofaunal communities of Uruguay (South America) vary between permanently open estuaries and open/closed coastal lagoons, or if they respond to the sediment composition. In Uruguay, estuaries and coastal lagoons vary in the degree of connectivity to the sea and in the sediment composition; sediments in estuaries are characterized by fine-medium sands but sediments vary from lagoon to lagoon (either fine-medium or coarse sand). Taxa richness (total = 16) showed less temporal variability in lagoons than in estuaries, due to patterns of presence/absence of the less abundant taxa. However, no major response to habitat was found in the most abundant groups: polychaetes (6% of total fauna) were on average 5% more abundant in lagoons than in estuaries. Some level of zonation, within estuaries and lagoons, was found in the most abundant groups, nematodes (63% of total fauna) and copepods (15%) in response to medium and fine sands. In addition, sediment type modulated seasonal patterns in the frequency of presence/absence in ostracods, polychaetes and oligochaetes. For instance, in polychaetes and ostracods the increase in the frequency of absences, occurring from summer to winter, was stronger in lagoons and estuaries dominated by fine sands. The lagoon habitat appears to ameliorate the effects of unfavourable (winter) conditions in less abundant meiofaunal taxa. In summary, sediment fractions explain spatial patterns in the average abundance of organisms (e.g. nematodes) as well as the seasonal changes in frequency of presence/absence (e.g. polychaetes).

Colletotrichum species are associated with Apple bitter rot (ABR) and Glomerella leaf spot (GLS). Whereas both apple diseases occur frequently in Brazil, only the former has been reported in Uruguay. This work was aimed at identifying and comparing morpho-cultural characteristics and pathogenic variability of thirty-nine Colletotrichum isolates from both countries. Sequencing of the internal transcribed spacer (ITS) rDNA, glyceraldehyde-3-phosphate dehydrogenase (GAPDH), and β-tubulin (TUB2) allowed the identification of three species causing ABR and GLS in Brazil, i.e., Colletotrichum fructicola, Colletotrichum karstii, and Colletotrichum nymphaeae; and three species causing ABR in Uruguay, i.e., C. fructicola, Colletotrichum theobromicola, and Colletotrichum melonis. Six groups of colony colours were recorded with group 1 (mycelium white to pink and in reverse pinkish) and group 2 (mycelium white to grey and in reverse pinkish) the most frequent. Isolates of C. fructicola and C. theobromicola were sensitive to benomyl, while C. karstii, C. nymphaeae, and C. melonis were resistant. Conidia were predominantly cylindrical for C. fructicola and C. karstii, fusiform for C. nymphaeae and C. melonis, and obclavate for C. theobromicola. Brazilian isolates caused ABR in wounded fruits, but only five in non-wounded ones. Uruguayan isolates produced symptoms in fruits with or without previous wounding. All Brazilian isolates from GLS and twelve from ABR were able to cause GLS symptoms, while a sole Uruguayan ABR-isolate caused leaf spot symptoms. This study gives a better insight on the new species causing apple disease in both countries and discusses their pathogenic potential. Copyright © 2014 The British Mycological Society.

Depression is one of the major contributors to the global burden of diseases; however, population-based data in South America are limited. We conducted a population-based cross sectional study with 7524 participants, aged 35-74 years old, recruited between February 2010 and December 2011 from randomly selected samples in 4 cities (Bariloche and Marcos Paz, Argentina; Temuco, Chile; and Pando-Barros Blancos, Uruguay). Major Depressive Episode (MDE) was assessed using the Patient Health Questionnaire (PHQ) - 9. The overall prevalence of MDE was 14.6% (95% CI: 13.6, 15.6). However, there was a geographical variability of up to 3.7 folds between different cities being 5.6% (95% CI: 4.6, 6.7) in Marcos Paz, Argentina; 9.5% (95% CI: 8.2, 10.9) in Bariloche, Argentina; 18.1% (95% CI: 16.3, 20.0) in Temuco, Chile, and 18.2 (95% CI: 16.3, 20.2) in Pando-Barros Blancos, Uruguay. The multivariate model showed that, adjusted by location, being female, being between 35 and 44 years old, having experienced at least one stressful life event, currently smoking, and having a history of chronic medical diseases were independently associated with an increased risk of MDE, while having higher education and being married or living with a partner reduced the risk of MDE. These results are representative of the selected cities included in the study. As such extrapolation to the general populations of Argentina, Chile, and Uruguay should be done with caution CONCLUSIONS: This study showed a high prevalence and variability of MDE in the Southern Cone of Latin America.

ABSTRACT Early growth is an important indicator of health and wellbeing of children and a good predictor of adult health. The objective of this study was to examine trends and determinants of overweight and stunting among infants aged 0 to 23 month(s) over the past decade (1999-2011) in Uruguay. Data were used from four large representative samples of 11,056 infants aged 0-23 month(s), who attended public and private health services in 1999, 2003, 2007, and 2011, using a similar methodology. Linear regression analysis was used for assessing trends in early growth indices and binary logistic regression to estimate the probability of being stunted and overweight. Although prevalence of overweight fell from 12.5% (1999) to 9.5% (2011) and stunting from 13.6% to 10.9% respectively, both rates remained higher than expected. Low birthweight (LBW) was the main predictor of stunting [OR 6.5 (5.6-7.6)] and macrosomia of overweight [6.7 (5.3-8.3)]. We did not observe changes in LBW (7.8-8.8%) or macrosomia (5.9-6.7%) over the last decade. Boys showed increased chance of being overweight [OR 1.2 (1.04-1.3)]. Being stunted doubles the chances of being overweight [OR 2.5 (2.2-3.0)]. Overweight [OR 7.1 (6.1-8.3)], LBW [OR 13.2 (11.0-15.9)], and non-breastfed infants [OR 1.9 (1.7-2.1)] showed rapid weight gain. Uruguay has taken positive steps to decline the prevalence of stunting and overweight but both remain excessively high. PMID:25895193

This study investigates the short-term impact on the quantity and quality of births of an abortion reform in Uruguay that legalised termination of pregnancy until the 12 th week of pregnancy in the short run. We employ a differences-in-differences approach, comprehensive administrative records of births, and a novel identification strategy based on the planned or unplanned nature of pregnancies that came to term. Our results suggest that this policy change has led to an 8% decline in the number of births from unplanned pregnancies, driven by the group of mothers aged between 20 and 34 years old who have secondary education. This decline has triggered an increase in the average quality of births in terms of more intensive prenatal control care and a lower probability of births among single mothers. Furthermore, we document a positive selection process of births because of the reform, as adequate prenatal control care and Apgar scores rose among the affected demographic group.

First record of Smilodon fatalis Leidy, 1868 (Felidae, Machairodontinae) in the extra-Andean region of South America (late Pleistocene, Sopas Formation), Uruguay: Taxonomic and paleobiogeographic implications

The Felidae are known in South America from the Ensenadan Stage/Age onwards. Among them, machairodonts of the genus Smilodon stand out. Three species are recognized, and all three are present on the continent: S. gracilis from the early-middle Pleistocene in north-east Venezuela; S. fatalis, found only in Lujanian sediments on the west side of the Andes (north-west of Peru and south-west of Ecuador); and S. populator, which inhabited the eastern part of the Andes during the Ensenadan and Lujanian. This distribution has led to the suggestion that the last two felids were allopatric during the Lujanian. Here, we report the first evidence of S. fatalis in the eastern part of the continent (Sopas Formation, late Pleistocene of Uruguay), based on an almost complete skull. This finding not only enlarges its distribution in South America but questions the idea of allopatric distribution. It also adds a new component to the mammalian predator trophic level of Uruguay, with the capacity to predate large South American herbivores and megaherbivores. A revision of materials previously assigned to S. populator in the extra-Andean zone of South America will be required.

A case-control study of oral and pharyngeal cancer involving interviews with 108 cases and 286 controls was carried out in the University Hospital of Montevideo, Uruguay. The study was restricted to males and cases afflicted with lip, salivary gland and nasopharyngeal cancer were excluded. Point estimates of RR associated with smoking variables, alcohol variables, nutritional items and ingestion of hot infusions of the herb Ilex paraguariensis ('Mate') were obtained by logistic regression analysis. Dark tobacco smokers showed a RR 3.4 times higher than light tobacco users and heavy drinkers of wine displayed an OR of 17.2. Mate exposure showed a significant dose-response, after adjustment for age, tobacco and alcohol intake, with a fivefold increase in risk for heavy consumers. Joint exposure to black tobacco and wine displayed very high risks and no significant interactions were observed. The results suggest that the high rates of oropharyngeal cancer could be explained by the multiplicative effect of black tobacco smoking, wine drinking and mate ingestion.

Tobacco control campaign in Uruguay: Impact on smoking cessation during pregnancy and birth weight.

Harris, Jeffrey E; Balsa, Ana Inés; Triunfo, Patricia

We analyzed a nationwide registry of all pregnancies in Uruguay during 2007-2013 to assess the impact of three types of tobacco control policies: (1) provider-level interventions aimed at the treatment of nicotine dependence, (2) national-level increases in cigarette taxes, and (3) national-level non-price regulation of cigarette packaging and marketing. We estimated models of smoking cessation during pregnancy at the individual, provider and national levels. The rate of smoking cessation during pregnancy increased from 15.4% in 2007 to 42.7% in 2013. National-level non-price policies had the largest estimated impact on cessation. The price response of the tobacco industry attenuated the effects of tax increases. While provider-level interventions had a significant effect, they were adopted by relatively few health centers. Quitting during pregnancy increased birth weight by an estimated 188 g. Tobacco control measures had no effect on the birth weight of newborns of non-smoking women. Copyright © 2015 Elsevier B.V.

Porcine Circovirus type 2 (PCV2) is a worldwide distributed pathogen and one of the most economically relevant swine infections. Four genotypes have been recognized and it is well known that PCV2a, PCV2b and PCV2d have a global distribution. However, the information about recombinant strains circulation and their influence in driving PCV2 evolution is a poorly studied area. In Uruguay, PCV2 associated symptoms began to be frequently observed in pigs from different farms since 2010. The main purpose of this study was to thoroughly investigate the molecular epidemiology of PCV2 in nationwide swine herds and free-living wild boars during the period 2010-2014, providing an extensive viral sequence dataset. Surprisingly, the findings revealed a predominance of recombinant strains circulation, evidencing for the first time in the field that PCV2 recombination can lead to the emergence of strains able to compete and potentially displace parental ones. In addition, the circulation of the genotypes PCV2d (29%), PCV2b (10.5%) and PCV2a (7.9%) were also observed. Since 2013, a high circulation of PCV2d was identified in the country and probably reflected the recent global scenario of the emergence of this genotype. In addition, fluctuations in the frequency of PCV2 infection in the period evaluated may suggest a limitation of biosecurity strategies implemented in Uruguay for the disease control, including the instability of vaccination practices. On the other hand, the sustained PCV2 infection observed in wild boar population and the similarity among circulating viral strains from these animals and domestic pigs, suggested that wild animals could serve as permanent reservoir of the disease. Altogether, this work put forward that many factors play a role in PCV2 heterogeneity including rapid viral spread and evolution, recombination, wide movement within national boundaries and multiples introduction events resulting of international trade.

Reform of abortion law in Uruguay: context, process and lessons learned.

Wood, Susan; Abracinskas, Lilián; Correa, Sonia; Pecheny, Mario

2016-11-01

In October 2012, a new law was approved in Uruguay that allows abortion on demand during the first 12 weeks of pregnancy, 14 weeks in the case of rape, and without a time limit when the woman's health is at risk or in the case of foetal anomalies. This paper analyses this legal reform. It is based on 27 individual and group interviews with key informants, and on review of primary documents and the literature. The factors explaining the reform include: secular values in society, favourable public opinion, a persistent feminist movement, effective coalition building, particular party politics, and a vocal public health sector. The content of the new law reflects the tensions between a feminist perspective of women's rights and public health arguments that stop short of fully recognizing women's autonomy. The Uruguayan reform shows that, even in Latin America, abortion can be addressed politically without electoral cost to the parties that promote it. On the other hand, the prevailing public health rationale and conditionalities built into the law during the negotiation process resulted in a law that cannot be interpreted as a full recognition of women's rights, but rather as a modified protectionist approach that circumscribes women's autonomy.

Laboratory diagnosis of human leptospirosis usually relies on indirect methods exploring specific immune response. Isolation and identification of the involved strains are cumbersome, but can provide biological resources for pathogenic studies and relevant information for guiding prevention and control measures. The aim of the research we are hereby reporting was the characterization of Leptospira isolates obtained from humans and the environment in Uruguay. Blood cultures were performed from early samples of 302 Uruguayan patients, mainly rural workers, and from 36 water samples taken from their living or working environments. Eight human isolates and seven environmental isolates were obtained and analyzed by end point Polymerase Chain Reaction (PCR), Multilocus Variable Number of Tandem Repeat Analysis (MLVA) and other molecular methods. Human isolates corresponded to several serogroups and serovars of Leptospira interrogans and Leptospira kirschneri species, probably reflecting the infection with similar involved Leptospira species and serovars of an extended animal reservoir in rural settings of the country, mostly dedicated to meat and dairy production. Culture-positive patients were older than usually affected workers, and presented signs and symptoms of severe illness. A high organic and circulating bacterial burden may explain an easier positive result from these workers' samples. Environmental isolates were mainly identified as Leptospira biflexa strains, with a single L. meyeri isolate of uncertain significance.

In the state of Rio Grande do Sul, the rainfall pattern is fairly regular and precipitation is well distributed throughout the year. The aim of this study was to evaluate the spatial and temporal distribution of precipitation in the Uruguay River basin from the determination of homogeneous regions based on the rainfall pattern. Values of 47 meteorological stations of the ANA (National Water Agency) from 1975 to 2005 were used, and values of Pacific sea surface temperature were collected from the National Oceanic and Atmospheric Administration, which is based on observed anomalies for different regions' niños (1 + niño 2, 3 niño, niño 4, niño 3 + 4). From the analysis of the results it was found that the study region showed five homogeneous regions. Knowing the time series of each region, it was possible to verify the regional variability in precipitation, indicating which regions have values above and below the climatological normal, and how the different indexes influence the rainfall pattern in the region.

There are no data available about the combined influence of the pregestational body mass index (PG-BMI) and the gestational weight gain (GWG) on the birth-weight (<3000 g, ≥4000 g) in Uruguay. To determine the prevalence of different categories of PG-BMI and GWG and then find out combined and independent risk at birth: <3000 g or intrauterine growth restriction (IUGR) and ≥ 4000 g (macrosomia) on a nationwide sample of mothers and newborns. Cohort study with prospective data from 23,832 pregnant women, with classification of the pregestational nutrition status according to the US PG-BMI pattern. GWG was classified according to a proposal from Denmark. The independent and combined risks from the different categories of PG-BMI and GWG with IUGR and macrosomia were determined by means of relative risk (RR). RR for RCIU and macrosomia were statistically relevant in their independent association with PGBMI and GWG. A high risk for IUGR was identified in pregnant women with low PG-BMI and a high risk for macrosomia in those with a high PG-BMI (overweight or obesity). Also the analysis of the combined influence revealed significant associations between PG-BMI and GWG. There is an independent and combined effect of the mothers variables on the perinatal results. We suggest comparing this study results, where categories were taken from the US PG-BMI pattern and from the Danish GWG pattern, with other patterns. Copyright AULA MEDICA EDICIONES 2014.

Conchostracans from the Tacuarembó Formation s.s. of Uruguay are reassigned to the subgenus Orthestheria (Migransia) Chen and Shen. They show more similarities to genera of Late Jurassic age in the Congo Basin and China than to those of Early Cretaceous age. On the basis of the character of the conchostracans, we suggest that the Tacuarembó Formation is unlikely to be older than Late Jurassic. It is probably Kimmeridgian, but an Early Cretaceous age cannot be excluded. This finding is consistent with isotopic dating of the overlying basalts, as well as the age range of recently described fossil freshwater sharks.

U-Pb age constraints for the La Tuna Granite and Montevideo Formation (Paleoproterozoic, Uruguay): Unravelling the structure of the Río de la Plata Craton

The Río de la Plata Craton is a continental block that crops out in Uruguay, eastern Argentina, southernmost Brazil and Paraguay. It comprises in Uruguay the Piedra Alta, Tandilia and Nico Pérez terranes, separated by the Colonia and the Sarandí del Yí megashears. The La Tuna Granite, which intrudes the Araminda metasandstones in the Tandilia Terrane, was considered Cambrian in age and the intruded sandstones were assigned to the Neoproterozoic Piedras de Afilar Formation. We show that the granite is Paleoproterozoic in age and that the host metasandstones do not belong to the Piedras de Afilar Formation, but to the Paleoproterozoic Montevideo Formation. U-Pb LA ICP-MS of zircon ages for the La Tuna Granite yielded a concordant crystallization age of 2156 ± 26 Ma. Furthermore a metamorphic event at 2010 ± 9 Ma is revealed by Pb stepwise leaching dating of monazites. U-Pb detrital zircon ages of the host Araminda metasandstone yield an upper intercept discordia age of 2152 ± 29 Ma, which marks the intrusion of the La Tuna pluton, and which is in accordance with the zircon U-Pb LA ICP MS constraints. A concordant U-Pb detrital zircon age of 2465 ± 40 Ma provides a maximum depositional age constraint for the metapsammites. Comparing quartz arenites of the Ediacaran Piedras de Afilar Formation with the Araminda metaquartzites, we conclude that they are very similar regarding petrology but they differ in age and metamorphic overprint. Detrital zircons in quartz arenites of the Piedras de Afilar Formation show youngest ages of 1.0 Ga. On the other hand, detrital zircons recovered from the Araminda metasandstones and the age of the intruding granite allow interpreting a depositional age between 2465 and 2150 Ma. Nd model ages show crustal residence times in average more than 200 myr older for the Tandilia Terrane both in Uruguay and Argentina, with a significant Neoarchean component, which is lacking in the Piedra Alta Terrane. Whereas the Piedra Alta Terrane was

Hepatitis E virus (HEV) infection is an issue of public health concern in high-income and non-endemic countries. Increasing evidence supports the hypothesis of a zoonotic route as the main mode of infection in this epidemiological setting, since the transmission of genotypes HEV-3 and HEV-4 from reservoirs to humans has been demonstrated. In America, studies have confirmed the circulation of HEV in pig herds but the zoonotic role of wild boars has never been evaluated. Uruguay has a high burden of HEV- associated acute hepatitis, and a close phylogenetic relationship was observed among human HEV-3 strains and European isolates detected in swine. However in this context, swine herds have never been surveyed. Herein is reported a survey of HEV in swine herds, pigs at slaughter-house and free-living wild boar populations. Two-hundred and twenty sera and 150 liver tissue samples from domestic pigs, and 140 sera from wild boars were tested for HEV by ELISA and PCR-based approaches. All tested swine farms resulted seropositive with an overall rate of 46.8%. In turn, 22.1% of the wild boars had anti-HEV antibodies. HEV RNA was detected in 16.6% and 9.3% of liver samples from slaughter-age pigs and adult wild boars sera, respectively. Three strains from domestic pig were also amplified by nested-PCR approaches. By contrast, none of the positive samples obtained from wild boars could be confirmed by nested-PCR. Phylogenetic analysis revealed a very high nucleotide identity among swine strains and sequences obtained from humans in Uruguay. Results showed that HEV is widely distributed among swine herds in Uruguay. Additionally, this study evidences for the first time in the American continent that wild boar populations are a reservoir for HEV, though its zoonotic role remains to be elucidated. Altogether, data presented here suggest a high zoonotic risk of HEV transmission from swine to humans. Copyright © 2017 Elsevier B.V. All rights reserved.

Little research has been conducted to determine the psychosocial and behavioral impacts of smoke-free policies in middle-income countries. Cross-sectional data were analyzed from the 2006 waves of the International Tobacco Control Policy Evaluation. Survey comparing adult smokers in Mexico (n = 1,080), where smoke-free legislation at that time was weak, and Uruguay (n = 1,002), where comprehensive smoke-free legislation was implemented. Analyses aimed to determine whether exposure to smoke-free policies and perceived antismoking social norms were associated with smokers' receiving cues about the bothersome nature of secondhand smoke (SHS), with smokers' reactance against such cues, and with smokers' level of support for smoke-free policies in different venues. In bivariate analyses, Uruguayan smokers were more likely than Mexican smokers to experience verbal anti-SHS cues, lower reactance against anti-SHS cues, stronger antismoking societal norms, and stronger support for 100% smoke-free policies in enclosed workplaces, restaurants, and bars. In multivariate models for both countries, the strength of voluntary smoke-free policies at home was independently associated with support for smoke-free policies across all venues queried, except for in bars among Uruguayans. Perceived strength of familial antismoking norms was consistently associated with all indicators of the social acceptability of smoking in Uruguay but only with the frequency of receiving anti-SHS verbal cues in Mexico. These results are generally consistent with previous research indicating that comprehensive smoke-free policies are likely to increase the social unacceptability of smoking and that resistance against such policies is likely to diminish once such policies are in place.

2016-01-19

In the present study in secondary schools and hospitals in Uruguay (N = 187), we examined the relationship between feeling the victim of mobbing and a perceived loss of status. Nearly all forms of mobbing were more prevalent among hospital employees than among school employees. Among hospital employees, 40.4%, and among school employees, 23.9% reported being the victim of mobbing at least once a week. Being the victim of mobbing was, in both hospitals and schools, more prevalent among older employees, and in hospitals, among employees who were more highly educated and who had been employed for a longer time. Men and women did not differ in reporting that one was a victim of mobbing, but men reported more perceived loss of status than women. However, among women, being the victim of mobbing was much more strongly related to experiencing a loss of status than among men. Several explanations for this gender difference and the practical and theoretical implications of the results are discussed. © The Author(s) 2016.

Early archosauromorph remains from the Permo-Triassic Buena Vista Formation of north-eastern Uruguay

The Permo-Triassic archosauromorph record is crucial to understand the impact of the Permo-Triassic mass extinction on the early evolution of the group and its subsequent dominance in Mesozoic terrestrial ecosystems. However, the Permo-Triassic archosauromorph record is still very poor in most continents and hampers the identification of global macroevolutionary patterns. Here we describe cranial and postcranial bones from the Permo-Triassic Buena Vista Formation of northeastern Uruguay that contribute to increase the meagre early archosauromorph record from South America. A basioccipital fused to both partial exoccipitals and three cervical vertebrae are assigned to Archosauromorpha based on apomorphies or a unique combination of characters. The archosauromorph remains of the Buena Vista Formation probably represent a multi-taxonomic assemblage composed of non-archosauriform archosauromorphs and a ‘proterosuchid-grade’ animal. This assemblage does not contribute in the discussion of a Late Permian or Early Triassic age for the Buena Vista Formation, but reinforces the broad palaeobiogeographic distribution of ‘proterosuchid grade’ diapsids in Permo-Triassic beds worldwide.

El método en la Psicología Comunitaria, Paidos, Buenos Aires, pp 229-256, 2004) as a paradigmatic dimension of community psychology. The field of SP, the characteristics of certain SPs and the role of SP in the production and reproduction of the subjectivities of those subject to them in Uruguay are described and an analysis given of the challenge posed by going from a compensatory or palliative to a transformative mode of SP. It is proposed that identification of, and understanding and intervention in, psychosocial processes in the field are the keys to maximising the likelihood of SPs assuming a transformative character. Psychosocial aspects and participatory processes implicit in the relationship between the State and civil society are discussed. Finally, some orientations for community psychological intervention in this field of action are proposed.

To describe working and employment conditions, and health status between non-agricultural employees with a written contract from Colombia, Argentina, Chile, Central America and Uruguay. We compared data from the first working condition surveys (WCS) of Colombia, Argentina, Chile, Central America and Uruguay. For comparative purposes, we selected a subsample of 15 241 non-agricultural employees aged 18-64 years and working with a written contract. We calculated prevalences and 95% CIs for the selected variables on working and employment conditions, and health status, separated by sex. Across all countries, at least 40% of women and 58% of men worked >40 hours a week. The most prevalent exposures were repetitive movements, followed by noise and manual handling, especially among men. Psychosocial exposures were very common among both sexes. Workers in Chile (33.4% of women and 16.6% of men) and Central America (24.3% of women and 19.1% of men) were more likely to report poor self-perceived health and were least likely to do so in Colombia (5.5% of women and 4.2% of men). The percentage of workers reporting occupational injuries was <10% across all countries. This study provides, for the first time, a broad picture of work and health in different Latin American countries, based on the national WCSs available. This allows for a better understanding of occupational health and could serve as a baseline for future research and surveillance of work and health in the Region. However, greater efforts are needed to improve WCSs comparability. Published by the BMJ Publishing Group Limited.

Discussion These results are generally consistent with previous research indicating that comprehensive smoke-free policies are likely to increase the social unacceptability of smoking and that resistance against such policies is likely to diminish once such policies are in place.

Abstract The rice crop and associated ecosystems constitute a rich mosaic of habitats that preserve a rich biological diversity. Spiders are an abundant and successful group of natural predators that are considered efficient in the biocontrol of the major insect pests in agroecosystems. Spider diversity in different stages of the rice crop growth from eastern Uruguay was analysed. Field study was developed on six rice farms with rotation system with pasture, installed during intercropping stage as cover crop. Six rice crops distributed in three locations were sampled with pitfall and entomological vaccum suction machine. Sixteen families, representing six guilds, were collected. Lycosidae, Linyphiidae, Anyphaenidae and Tetragnathidae were the most abundant families (26%, 25%, 20% and 12%, respectively) and comprised more than 80% of total abundance. Other hunters (29%), sheet web weavers (25%) and ground hunters (24%) were the most abundant guilds. Species composition along different crop stages was significantly different according to the ANOSIM test. The results showed higher spider abundance and diversity along the crop and intercrop stages. This study represents the first contribution to the knowledge of spider diversity associated with rice agroecosystem in the country. PMID:29755261

Harvey was formed around 17 august with maximum winds 40 miles/hour. At the moment, Irma formation started in 20 august faster becoming a hurricane category five. Some days before these two events, the Uruguay and Brazil coast suffered a recede in the oceans near Punta del Este and Rio Grande do Sul it happened in the week of 11 august. The energy accumulated in the recede of waters was not released by a tsunami and the water slowly was back to the shore. This event repeated at August 25, however at higher latitudes as in Parana and Sao Paulo. And consequent high tides in Chile again. The absence of a recurrent tsunami at the Brazilian coast indicates the energy accumulated from the recede ocean was released as a tsunami in the oceans, it became another huge hurricane formation as Jose and Katia. All those events pointed out for an atmospheric pressure disturbance on the Atlantic East Coast. In South America happened a suddenly increase at the atmospheric pressure which made the ocean waves receded for many days. A similar disturbance happened in Caribe area resulting in several huge hurricanes.

A perfect storm? Welfare, care, gender and generations in Uruguay.

This article claims that welfare states modelled on a contributory basis and with a system of entitlements that assumes stable two-parent families, a traditional breadwinner model, full formal employment and a relatively young age structure are profoundly flawed in the context of present-day challenges. While this is true for affluent countries modelled on the Bismarckian type of welfare system, the costs of the status quo are even more devastating in middle-income economies with high levels of inequality. A gendered approach to welfare reform that introduces the political economy and the economy of care and unpaid work is becoming critical to confront what may very well become a perfect storm for the welfare of these nations and their peoples. Through an in-depth study of the Uruguayan case, the authors show how the decoupling of risk and protection has torn asunder the efficacy of welfare devices in the country. An ageing society that has seen a radical transformation of its family and labour market landscapes, Uruguay maintained during the 1980s and 1990s a welfare state that was essentially contributory, elderly and male-oriented, and centred on cash entitlements. This contributed to the infantilization of poverty, increased the vulnerability of women and exacerbated fiscal stress for the system as a whole. Furthermore, because of high levels of income and asset inequality, the redistribution of risk between upper- and lower-income groups presented a deeply regressive pattern. The political economy of care and welfare has begun to change in the last decade or so, bringing about mild reforms in the right direction; but these might prove to be too little and too late.

Tobacco industry's ITGA fights FCTC implementation in the Uruguay negotiations.

To illustrate how the tobacco industry' front group, the International Tobacco Growers Association (ITGA), mobilised tobacco farmers to influence the fourth session of the Conference of the Parties (COP4) negotiations and defeat the adoption of Framework Convention on Tobacco Control Articles 9 and 10 Guidelines and Articles 17 and 18 progress report. A review of COP4 documents on Articles 9, 10, 17 and 18 was triangulated with relevant information from tobacco industry reports, websites of British American Tobacco, Philip Morris International and ITGA, presentations by tobacco industry executives and internal industry documents from the Legacy Tobacco Documents Library website. Philip Morris International and British American Tobacco rejected Articles 9 and 10 draft Guidelines claiming that banning ingredients in cigarettes will render burley leaf less commercially viable making tobacco growers in many countries suffer economic consequences. They claimed the terms 'attractiveness' and 'palatability' are not appropriate regulatory standards. The ITGA launched a global campaign to mobilise farmers to reject the draft Guidelines at COP4 in Uruguay. Tobacco producers, Brazil, Philippines, Tanzania, Zambia, Malawi and Zimbabwe, sent large delegations to COP4 and participated actively in the negotiation on the draft Guidelines. Partial Guidelines on Articles 9 and 10 on product regulation and disclosure were adopted. COP4's work on Article 17 provides guidance on viable alternatives, but the ITGA is opposed to this and continues fight crop substitution. Despite ITGA's international campaign to thwart the Guidelines on Articles 9 and 10 and a strong representation from tobacco-growing countries at COP4, the outcome after intense negotiations was the adoption of Partial Guidelines and work on Articles 17 and 18 to proceed.

Livestock production has been challenged as a large contributor to climate change, and carbon footprint has become a widely used measure of cattle environmental impact. This analysis of fifteen beef grazing systems in Uruguay quantifies the range of variation of carbon footprint, and the trade-offs with other relevant environmental variables, using a partial life cycle assessment (LCA) methodology. Using carbon footprint as the primary environmental indicator has several limitations: different metrics (GWP vs. GTP) may lead to different conclusions, carbon sequestration from soils may drastically affect the results, and systems with lower carbon footprint may have higher energy use, soil erosion, nutrient imbalance, pesticide ecotoxicity, and impact on biodiversity. A multidimensional assessment of sustainability of meat production is therefore needed to inform decision makers. There is great potential to improve grazing livestock systems productivity while reducing carbon footprint and other environmental impacts, and conserving biodiversity. Copyright © 2014 Elsevier Ltd.

BNOT was created and regulated in 1977 and started its operation in 1978 according to the Decree No. 86/1977. By the Decree 248/005 is transformed in the National Institute of Donation and Transplantation of Cells, Tissues and Organs (Instituto Nacional de Donación y Trasplante de Células, Tejidos y Organos--INDT). The organisation has been operating within the State University Medical School and the Public Health Secretary and it is the governmental organisation responsible for the regulation, policy and management of donation and transplantation in Uruguay. By the Decree 160/2006 is responsible for human cells and tissues regulation too. The participation of the INDT in the IAEA program facilitated the introduction of the radiation sterilisation technique for the first time in the country. The radiation sterilisation of tissues processed by INDT (ex BNOT), was initially carried out in the 60 Cobalt Industrial Plant in the National Atomic Energy Commission of Argentina and now is carried out in INDT, using a Gamma Cell 220 Excel, which was provided by the IAEA through the national project URU/7/005. The results of the implementation of tissues, quality control and quality management system, are showed.

Human–megafauna interaction in the Americas has great scientific and ethical interest because of its implications on Pleistocene extinction. The Arroyo del Vizcaíno site near Sauce, Uruguay has already yielded over 1000 bones belonging to at least 27 individuals, mostly of the giant sloth Lestodon. The assemblage shows some taphonomic features suggestive of human presence, such as a mortality profile dominated by prime adults and little evidence of major fluvial transport. In addition, several bones present deep, asymmetrical, microstriated, sharp and shouldered marks similar to those produced by human stone tools. A few possible lithic elements have also been collected, one of which has the shape of a scraper and micropolish consistent with usage on dry hide. However, the radiocarbon age of the site is unexpectedly old (between 27 and 30 thousand years ago), and thus may be important for understanding the timing of the peopling of America. PMID:24258717

Interventions aimed at changing dietary patterns should be designed based on the main motives underlying the food choices of specific target populations. The aim of the present study was to identify motives underlying food choice and barriers to healthy eating among consumers in two socioeconomic levels in Uruguay. Eleven focus groups were carried out with a total of 76 participants. Six of the groups involved low income participants and the others were conducted with middle income participants. Discussions were held around frequently consumed products, motives underlying food choices and barriers to healthy eating. Results confirmed the strong influence of income level on motives underlying food choice and barriers to the adoption of healthy eating. Low income participants described their choices as mainly driven by economic factors and satiety, whereas convenience was the main determinant of food selection for middle income participants. Implications for the design of public policies targeted at each group are discussed.

Structural evolution of the Sarandí del Yí Shear Zone, Uruguay: kinematics, deformation conditions and tectonic significance

The Sarandí del Yí Shear Zone is a crustal-scale shear zone that separates the Piedra Alta Terrane from the Nico Pérez Terrane and the Dom Feliciano Belt in southern Uruguay. It represents the eastern margin of the Río de la Plata Craton and, consequently, one of the main structural features of the Precambrian basement of Western Gondwana. This shear zone first underwent dextral shearing under upper to middle amphibolite facies conditions, giving rise to the reactivation of pre-existing crustal fabrics in the easternmost Piedra Alta Terrane. Afterwards, pure-shear-dominated sinistral shearing with contemporaneous magmatism took place under lower amphibolite to upper greenschist facies conditions. The mylonites resulting from this event were then locally reactivated by a cataclastic deformation. This evolution points to strain localization under progressively retrograde conditions with time, indicating that the Sarandí del Yí Shear Zone represents an example of a thinning shear zone related to the collisional to post-collisional evolution of the Dom Feliciano Belt that occurred between the Meso- to Neoproterozoic (>600 Ma) and late Ediacaran-lower Cambrian times.

About 90% of the sediments generated by weathering and erosion on land get finally deposited at the ocean margins. The sediment distribution processes and landscape evolution on land are relatively well understood, but comparably little is known about the role and relative importance of marine sediment dynamics in controlling the architectural evolution of ocean margins. Important players include hemi-pelagic settling, down-slope and current-controlled along-slope sediment transport, depositional and post-depositional sedimentary processes (e.g. consolidation and diagenesis), as well as the destabilization of sediment bodies and their erosion. Submarine landslides in this context thus may represent an important sediment transport process, but also a major geo-hazard due to the increasing number of offshore constructions as well as their potential to instantaneously displace large water masses triggering waves in densely populated coastal areas. Here we present first results from a seagoing expedition that aimed at investigating the interaction processes of sediment redistribution, partitioning, deposition and diagenesis from the coast to the deep-sea along the western South-Atlantic passive continental margin. During RV Meteor Cruise M78/3 in May-July 2009 the shelf, slope and rise offshore Argentina and Uruguay have been investigated by means of hydroacoustic and seismic mapping as well as geological sampling with conventional coring tools as well as the new MARUM seafloor drill rig (MeBo) that revealed recovery of geological strata sampled from up to 50m below seafloor. The working area is characterized by a high amount of fluvial input by the Rio de la Plata river. The continental slope is relatively wide and shows average slope gradients between 1 and 2.5 but locally higher slope gradients may occur (>5). The transition for the continental rise with low slope gradients is found in ~ 3000m water depth. The working area is located in a highly dynamic

Spargana are plerocercoid larvae of cestode tapeworms of the genus Spirometra, Family Diphyllobothriidae, parasitic to frogs, reptiles, birds and mammals. This parasitic disease in humans can be transmitted through the use and consumption of amphibians and reptiles. The available knowledge about Spirometra in South America is scarce, and there are only a few reports on the occurrence of sparganum in amphibians and reptiles, many of them published in old papers not easily available to researchers. In this work we present a review on this topic, provide new records in two species of amphibians and 7 species of reptiles from Brazil and Uruguay respectively. We also summarize current knowledge of Spirometra in the continent, along with an updated of host taxonomy. We could gather from the literature a total of 15 studies about amphibian and reptile hosts, published between 1850 and 2016, corresponding to 43 case reports, mostly from Brazil (29) and Uruguay (8), Argentina (3), Peru (2), and Venezuela (1); the majority of them related to reptiles (five lizards and 26 snake species), and 14 corresponded to amphibians (9 anurans). Plerocercoid larvae were located in different organs of the hosts, such as subcutaneous tissue, coelomic cavity, peritoneum, and musculature. The importance of amphibians and reptiles in the transmission of the disease to humans in South America is discussed. Relevant issues to be studied in the near future are the taxonomic characterization of Spirometra in the region and the biological risk of reptile meat for aboriginal and other rural communities.

Participatory research towards co-management: lessons from artisanal fisheries in coastal Uruguay.

PubMed

Trimble, Micaela; Berkes, Fikret

2013-10-15

Participatory research has become increasingly common in natural resources management. Even though participatory research is considered a strategy to facilitate co-management, there is little empirical evidence supporting this. The objective of the present paper is to analyze the contributions of participatory research to help encourage the emergence of co-management, based on a case study in Piriápolis artisanal fishery in coastal Uruguay (where management has been top-down). We argue that participatory research involving artisanal fishers, government, and other stakeholders (university scientists and NGOs) can be a key stimulus towards co-management. We build this argument by considering "seven faces" by which co-management can be analyzed: (1) as power sharing; (2) as institution building; (3) as trust building; (4) as process; (5) as learning and knowledge co-production; (6) as problem solving; and (7) as governance. Our findings show that participatory research had an impact on these various faces: (1) power was shared when making research decisions; (2) a multi-stakeholder group (POPA), with a common vision and goals, was created; (3) trust among participants increased; (4) the process of group formation was valued by participants; (5) stakeholders learned skills for participation; (6) two problem-solving exercises were conducted; and (7) a diversity of stakeholders of the initial problem identified by fishers (sea lions' impact on long-line fishery) participated in the process. The case shows that participatory research functions as a platform which enhances learning and knowledge co-production among stakeholders, paving the way towards future co-management.

This study analyzed the temporal dynamics of total microcystin LR concentrations between the years of 2012 and 2015 in the Bonete, Baygorria and Palmar hydroelectric generation reservoirs in the central region of the Negro River, Uruguay. The three reservoirs showed differents total microcystin LR concentration, with no significant differences among them. Over 20 sampling dates, the three reservoirs exhibited total microcystin LR concentrations on eight occasions that corresponded to a slight to moderate human health risk according to WHO guideline values for recreational waters. By determining the concentration of microcystin LR in cyanobacterial biomass, we identified cyanobacterial populations that occurred over time with varying degrees of toxin production (maximal 85.4 µg/mm 3 ). The microcystin LR concentration in Bonete was positively correlated with temperature (r = 0.587) and cyanobacterial biomass (r = 0.736), in Baygorria with cyanobacterial biomass (r = 0.521), and in Palmar with temperature (r = 0.500) and negatively correlated with ammonia (r = -0.492). Action is needed to reduce the presence of toxic cyanobacteria in these systems. A decrease in the use of agrochemicals and management changes in the reservoir basins could be successful long-term measures.

In order to determine the role of meat consumption and related nutrients in the etiology of prostate cancer we conducted a case-control study among Uruguayan men in the time period 1998-2007. The study included 464 cases and 472 controls, frequency matched for age and residence. Both series were drawn from the four major public hospitals in Montevideo. Unconditional logistic regression was used to estimate odds ratios (ORs) and 95 % confidence intervals (95 % CI) of prostate cancer by quartiles of meat intake and related nutrients. The highest vs. the lowest quartile of intake of total meat (OR = 5.19, 95 % CI 3.46-7.81), red meat (OR = 4.64, 95 % CI 3.10-6.95), and processed meat (OR = 1.78, 95% CI 1.22-2.59) were associated with increased risk of prostate cancer. Meat nutrients were directly associated with the risk of prostate cancer (OR for cholesterol 5.61, 95 % CI 3.75-8.50). Moreover, both total meat and red meat displayed higher risks among obese patients. This study suggests that total and red meat and meat nutrients may play a role in the etiology of prostate cancer in Uruguay.

U-Pb geochronology of Martín García, Sola, and Dos Hermanas Islands (Argentina and Uruguay): Unveiling Rhyacian, Statherian, Ectasian, and Stenian of a forgotten area of the Río de la Plata Craton

The Río de la Plata Craton is one of the three major cratons of South America. The craton is largely covered by sedimentary basins where its most exposed area is Buenos Aires-Piedra Alta Province (Chernicoff et al., 2014). This province includes the Martín García Island in the confluence of Uruguay River and the Río de la Plata estuary. Despite to be a reference area for the craton the Martín García Island lacks modern geological investigation. We present U-Pb SIMS (secondary ion mass spectrometer) geochronological data on zircon and titanite, as well as Hf isotope determinations on zircon, from rocks of Martín García Island (Argentina), Sola and Dos Hermanas Islands (Uruguay) and from Paso Severino Formation (Uruguay). We investigated: 1) Rhyacian intermediate-to acidic plutonic, arc-type rocks of the Florida Belt dated between 2090 Ma and 2115 Ma, derived from juvenile Neoarchean crust (TDMHf: 2.52 Ga; average εHf: +3.62); 2) Rhyacian metadacite (San José metamorphic belt) of 2127 Ma; 3) Statherian metagabbros of 1724-1734 Ma, with Transplatense inheritance; 4) Early Ectasian metagabbro of 1392 Ma, with Rhyacian inheritance; and 5) Stenian metagabbros of 1193 Ma (TDMHf: 2.00 Ga, εHf: 0.1). Most of the dated orthogneisses show Brasilian-age (from 778 to 550 Ma) Pb loss in the zircons, interpreted to be caused by shearing or uplifting during Neoproterozoic. The results show that the area is not exclusively Rhyacian in age but encompasses Statherian, Ectasian, and Stenian gabbros. The last two are interpreted as distal intrusions associated to the Sunsás Orogen. All post-Transplatense metagabbros have geochemical signature of island arc basalt derived from primitive mantle with enrichment of LILE and depletion of HFSE. These characteristics point to the recurrence of magma chambers intermittently active during the Rhyacian, Statherian, Ectasian, and Stenian, all with a similar source. The term "Transplatense" is used to replace "Trans-Amazonian" events

Glucose content and in vitro bioaccessibility were determined in raw and cooked pulp of Arapey, Cuabé, and Beauregard sweet potato varieties, as well as Maravilla del Mercado and Atlas winter squash, after zero, two, four, and six months of storage (14 °C, 80% relative humidity (RH)). The total glucose content in 100 g of raw pulp was, for Arapey, 17.7 g; Beauregard, 13.2 g; Cuabé, 12.6 g; Atlas, 4.0 g; and in Maravilla del Mercado, 4.1 g. These contents were reduced by cooking process and storage time, 1.1 to 1.5 times, respectively, depending on the sweet potato variety. In winter squash varieties, the total glucose content was not modified by cooking, while the storage increased glucose content 2.8 times in the second month. After in vitro digestion, the glucose content released was 7.0 times higher in sweet potato (6.4 g) than in winter squash (0.91 g) varieties. Glucose released by in vitro digestion for sweet potato stored for six months did not change, but in winter squashes, stored Atlas released glucose content increased 1.6 times. In conclusion, in sweet potato and winter squash, the glucose content and the released glucose during digestive simulation depends on the variety and the storage time. These factors strongly affect the supply of glucose for human nutrition and should be taken into account for adjusting a diet according to consumer needs. PMID:28665302

We studied HLA DQB1 allele frequencies and the relative risk (RR) of various genotypes in 72 type 1 diabetic patients and 40 control individuals in Uruguay. This is a tri-racial (Caucasian, Black and Indo-American) mixed population. The products of the polymerase chain reaction amplifications were hybridized with oligonucleotides by allele-specific oligonucleotide reverse or dot blot methods. Significant differences between these two groups were observed only for allele DQB1*0302 (35%, RR = 7.34, P<0.001). The frequency of the alleles carrying a non-aspartic acid residue at position 57 was significantly higher in the diabetic patients (85 vs 53%, P<0.001). In contrast, the frequency of Asp alleles was negatively associated with type 1 diabetes (RR = 0.20, P<0.001). The genotype DQB1*0302/DQB1*0201 (33%, RR = 5.41, P<0.05) was positively associated with this disease. The genotype frequencies associated with type 1 diabetes in our population were significantly different from what is known for Caucasian and Black populations as well as compared with another admixed population, from Chile.

Chemical bioprospecting is an important tool for generating knowledge regarding local human-threatened floras and for conservation management. For Baccharis L. (Asteraceae), several volatile components have been reported for Brazil, Argentina, Bolivia, and Chile as a result of bioprospection, but not for Uruguayan flora, which is composed of more than 50 native species. In this work, through collection of aerial parts of different species and volatile simultaneous-distillation extraction and gas chromatography-mass spectrometry analyses, twelve native species of Baccharis were studied (B. articulata, B. cultrata, B. genistifolia, B. gibertii, B. gnaphalioides, B. ochracea, B. phyteumoides, B. punctulata, B. crispa, B. dracunculifolia, B. linearifolia subsp. linearifolia, and B. spicata). A detailed analysis of the male and female volatile composition was conducted for the last four species. The profiles of B. cultrata, B. genistifolia, B. gibertii, and B. gnaphalioides are reported for the first time. Because half of the species analyzed in this work are in Uruguay and are threatened or potentially threatened by human economic activities, the importance of their conservation as natural, sustainable resources is highlighted. © 2018 Wiley-VHCA AG, Zurich, Switzerland.

Previously, we reported a rare X-linked disorder, Uruguay syndrome in a single family. The main features are pugilistic facies, skeletal deformities, and muscular hypertrophy despite a lack of exercise and cardiac ventricular hypertrophy leading to premature death. An ≈19 Mb critical region on X chromosome was identified through identity-by-descent analysis of 3 affected males. Exome sequencing was conducted on one affected male to identify the disease-causing gene and variant. A splice site variant (c.502-2A>G) in the FHL1 gene was highly suspicious among other candidate genes and variants. FHL1A is the predominant isoform of FHL1 in cardiac and skeletal muscle. Sequencing cDNA showed the splice site variant led to skipping of exons 6 of the FHL1A isoform, equivalent to the FHL1C isoform. Targeted analysis showed that this splice site variant cosegregated with disease in the family. Western blot and immunohistochemical analysis of muscle from the proband showed a significant decrease in protein expression of FHL1A. Real-time polymerase chain reaction analysis of different isoforms of FHL1 demonstrated that the FHL1C is markedly increased. Mutations in the FHL1 gene have been reported in disorders with skeletal and cardiac myopathy but none has the skeletal or facial phenotype seen in patients with Uruguay syndrome. Our data suggest that a novel FHL1 splice site variant results in the absence of FHL1A and the abundance of FHL1C, which may contribute to the complex and severe phenotype. Mutation screening of the FHL1 gene should be considered for patients with uncharacterized myopathies and cardiomyopathies. © 2016 American Heart Association, Inc.

Cannabis Social Clubs (CSCs) are a model of non-profit production and distribution of cannabis among a closed circuit of adult cannabis users. CSCs are now operating in several countries around the world, albeit under very different legal regimes and in different socio-political contexts. In this paper we describe and compare the legal framework and the self-regulatory practices of Cannabis Social Clubs in three countries (Spain, Belgium, and Uruguay). The objective of our comparative analysis is to investigate how CSCs operate in each of these countries. To foster discussions about how one might regulate CSCs to promote public health objectives, we conclude this paper with a discussion on the balance between adequate governmental control and self-regulatory competences of CSCs. The data used for this analysis stem from independently conducted local studies by the authors in their countries. Although the particular designs of the studies differ, the data in all three countries was collected through similar data collection methods: analysis of (legal and other documents), field visits to the clubs, interviews with staff members, media content analysis. We identified a number of similarities and differences among the CSCs' practices in the three countries. Formal registration as non-profit association seems to be a common standard among CSCs. We found nevertheless great variation in terms of the size of these organisations. Generally, only adult nationals and/or residents are able to join the CSCs, upon the payment of a membership fee. While production seems to be guided by consumption estimates of the members (Spain and Belgium) or by the legal framework (Uruguay), the thresholds applied by the clubs vary significantly across countries. Quality control practices remain an issue in the three settings studied here. The CSCs have developed different arrangements with regards to the distribution of cannabis to their members.

While it is known that toxic metals contribute individually to child cognitive and behavioral deficits, we still know little about the effects of exposure to multiple metals, particularly when exposures are low. We studied the association between children's blood lead and hair arsenic, cadmium, and manganese and their performance on the Bayley Scales of Infant Development III. Ninety-two preschool children (age 13–42 months) from Montevideo, Uruguay, provided a hair sample and 78 had a blood lead level (BLL) measurement. Using latent class analysis (LCA), we identified four groups of exposure based on metal concentrations: (1) low metals, (2) low-to-moderate metals, (3) high lead and cadmium, and (4) high metals. Using the four-group exposure variable as the main predictor, and fitting raw scores on the cognitive, receptive vocabulary, and expressive vocabulary scales as dependent variables, both complete-case and multiple imputation (MI) analyses were conducted. We found no association between multiple-metal exposures and neurodevelopment in covariate-adjusted models. This study demonstrates the use of LCA together with MI to determine patterns of exposure to multiple toxic metals and relate these to child neurodevelopment. However, because the overall study population was small, other studies with larger sample sizes are needed to investigate these associations. PMID:25694786

Coprophilous beetles represent an abundant and rich group with critical importance in the functioning of terrestrial ecosystems. Most coprophagous beetles have a stenotopic distribution in relation to vegetation types. Because of this, they are usually very sensitive to environmental changes and are considered well suited as bioindicator organisms. The aim of this study was to analyze variations in coprophilous beetle assemblages in natural and anthropogenic habitats. Coprophilous beetle communities were sampled monthly for 1 year using pitfall traps baited with cow dung, in native xeric upland forests, 15-years-old plantations of Pinus elliottii and pastures in Sierra de Minas, Lavalleja, Uruguay. A total of 7,436 beetles were caught and identified to species or morphospecies level. The most abundant families were Aphodiidae, Scarabaeidae, and Staphylinidae. Differences in species richness, abundance, Shannon index, evenness, and dominance were detected between habitats. Abundances of most frequent families were significantly higher in both kinds of forests. Species richness and diversity of Aphodiidae and Staphylinidae were higher in forests, while Scarabaeidae showed the highest richness and diversity in pine plantations. Species composition significantly differed between habitats. Uroxys terminalis Waterhouse and Ataenius perforatus Harold typified the assemblages in native forests and pine plantations and also discriminated both communities because of their differential pattern of abundance between habitats. Typifying species in pastures were Onthophagus hirculus, Ateuchus robustus (Harold), and Ataenius platensis Blanchard. Habitat type had a strong effect on the coprophilous beetle community structure and composition.

Background Uruguay is located at the southern border of Aedes aegypti distribution on the South American sub-continent. The reported dengue cases in the country are all imported from surrounding countries. One of the cities at higher risk of local dengue transmission is Salto, a border city with heavy traffic from dengue endemic areas. Methods We completed an intervention study using a cluster randomized trial design in 20 randomly selected ‘clusters’ in Salto. The clusters were located in neighborhoods of differing geography and economic, cultural and social aspects. Results Entomological surveys were carried out to measure the impact of the intervention on vector densities. Through participatory processes of all stakeholders, an appropriate ecosystem management intervention was defined. Residents collected the abundant small water holding containers and the Ministry of Public Health and the Municipality of Salto were responsible for collecting and eliminating them. Additional vector breeding places were large water tanks; they were either altered so that they could not hold water any more or covered so that oviposition by mosquitoes could not take place. Conclusions The response from the community and national programme managers was encouraging. The intervention evidenced opportunities for cost savings and reducing dengue vector densities (although not to statistically significant levels). The observed low vector density limits the potential reduction due to the intervention. A larger sample size is needed to obtain a statistically significant difference. PMID:25604764

Spatial variability of temperature was studied in relation to the berry basic composition and secondary compounds of the Tannat cultivar at harvest from vineyards located in Canelones and Montevideo, the most important wine region of Uruguay. Monitoring of berries and recording of temperature were performed in 10 commercial vineyards of Tannat situated in the southern coastal wine region of the country for three vintages (2012, 2013, and 2014). Results from a multivariate correlation analysis between berry composition and temperature over the three vintages showed that (1) Tannat responses to spatial variability of temperature were different over the vintages, (2) correlations between secondary metabolites and temperature were higher than those between primary metabolites, and (3) correlation values between berry composition and climate variables increased when ripening occurred under dry conditions (below average rainfall). For a particular studied vintage (2013), temperatures explained 82.5% of the spatial variability of the berry composition. Daily thermal amplitude was found to be the most important spatial mode of variability with lower values recorded at plots nearest to the sea and more exposed to La Plata River. The highest levels in secondary compounds were found in berries issued from plots situated as far as 18.3 km from La Plata River. The increasing knowledge of temperature spatial variability and its impact on grape berry composition contributes to providing possible issues to adapt grapevine to climate change.

Bioassays of two sites along the Rio Negro in Uruguay indicate ecotoxicity, which could be attributable to trace concentrations of lead in river sediments. Monthly samples at two sites at Baygorria and Bonete locations were analyzed for both particle size and lead. Lead was determined by atomic spectrometry in river water and sediment and particle size by sieving and sedimentation. Data showed that Baygorria's sediments have greater percentage of clay than Bonete's (20.4 and 5.8%, respectively). Lead was measurable in Baygorria's sediments, meanwhile in Bonete's, it was always below the detection limit. In water samples, lead was below detection limit at both sites. Bioassays using sub-lethal growth and survival test with Hyalella curvispina amphipod, screening with bioluminescent bacteria Photobacterium leiognathi, and acute toxicity bioassay with Pimephales promelas fish indicated toxicity at Baygorria, with much less effect at Bonete. Even though no lethal effects could be demonstrated, higher sub-lethal toxicity was found in samples from Baygorria site, showing a possible concentration of the contaminant in the clay fraction.

Most studies of sandy beach macrofauna have been restricted to semiterrestrial species and do not include insects when providing species richness and abundance estimates. Particularly, spatio-temporal patterns of community structure of the entomofauna inhabiting these ecosystems have been scarcely documented. This study assessed spatio-temporal distributional patterns of the night active entomofauna on a beach-dune system of Uruguay, including variations in species richness, abundance and diversity, and their relationship with environmental factors. A deconstructive taxonomic analysis was also performed, considering richness and abundance patterns separately for the most abundant insect Orders (Hymenoptera and Coleoptera) to better understand the factors which drive their patterns. We found clear temporal and across-shore patterns in the insect community inhabiting a land-ocean interface, which matched spatiotemporal variations in the environment. Abundance and species richness were highest in spring and summer, concurrently with high temperatures and low values of sediment moisture and compaction. Multivariate ordinations showed two well-defined species groups, which separated summer, autumn and spring samples from winter ones. Generalized Linear Models allowed us to describe a clear segregation in space of the most important orders of the insect community, with specific preferences for the terrestrial (Hymenoptera) and beach (Coleoptera) fringes. Hymenoptera preferred the dune zone, characterized by high elevation and low sand moisture and compaction levels, whereas Coleoptera preferred gentle slopes and fine and humid sands of the beach. Our results suggest that beach and dune ecosystems operate as two separate components in regard to their physical and biological features. The high values of species richness and abundance of insects reveal that this group has a more significant ecological role than that originally considered so far in sandy beach ecology.

The water activity (a(w)) and pH values of commercially available filled fresh pasta and gnocchi packed under modified atmosphere and manufactured in Argentina and Uruguay were examined. The retail survey included 58 samples (several brands) of filled pasta and 11 samples of gnocchi. Fillings consisted of different combinations of cheese (various types), beef, ricotta, ham, chicken, and spinach. The survey revealed that the a(w) values of the 58 samples of filled pasta ranged from 0.916 to 0.973, and their pH values ranged from 5.2 to 7.0. The a(w) of gnocchi was consistently higher and ranged from 0.936 to 0.983, with pH values from 4.8 to 6.4. Some samples of filled pasta and most gnocchi samples were found to have a(w) and pH values that would support growth of spores of Clostridium botulinum, if present, under conditions of temperature abuse (i.e., 30 degrees C).

Twenty-nine dairy farms were selected to determine the incidence of clinical mastitis, prevalence of sub-clinical mastitis and bacterial aetiology in the West Littoral Region of Uruguay. In samples taken by the owner and frozen at -20°C during a week the incidence rate of clinical mastitis was determined as 1.2 cases per 100 cow-months at risk. Staphylococcus aureus was the most common isolated pathogen in 37.5% of 40 milk samples from clinical cases obtained in 1 month. No bacteria grew in the 32.5% of the total samples. A sub-sample including 1077 dairy cows from randomly selected farms was used to determine the prevalence of sub-clinical mastitis. These samples were taken on one visit to each farm. The prevalence was 52.4% on a cow basis and 26.7% on an udder quarter basis. In 55.1% of the quarters of the selected animals with more than 300 000 cells/ml there was no growth. The isolated pathogens from sub-clinical cases and their relative frequencies were: Staphylococcus aureus 62.8%, Streptococcus agalactiae 11.3%, Enterococcus sp. 8%, coagulase-negative staphylococci 7.4%, Streptococus uberis 6.4%, Streptococcus dysgalactiae 1.8%, Escherichia coli 1.5% and Staphylococcus hyicus coagulase-positive 0.6%.

Marketing of unhealthy products has been identified as one of the main characteristics of the food environment that negatively affects children's eating patterns. Restrictions on advertising of unhealthy foods to children have already been imposed in different countries. However, marketing strategies are not limited to broadcast and digital advertising, but also include package design. In this context, the current study aimed to describe the food products targeted at children and sold in supermarkets in Montevideo, Uruguay, in terms of package design and nutrient profile. Two supermarkets in Montevideo were selected for data collection. In each supermarket, all products targeted at children were identified. Products were analyzed in terms of package design and nutritional profile, considering the Pan American Health Organization Nutrient Profile Model. A total of 180 unique products were identified, which included a wide range of product categories. The great majority of the products corresponded to ultra-processed products with excessive amounts of sodium, free sugars, total fat, saturated fat, and/or trans fat, which are not recommended for frequent consumption. Several marketing strategies were identified in the design of packages to attract children's attention and drive their preferences. The most common strategies were the inclusion of cartoon characters, bright colors, childish lettering, and a wide range of claims related to health and nutrition, as well as the products' sensory and hedonic characteristics. The study's findings provide additional evidence on the need to regulate packaging of products targeted at children.

A study was conducted in the city of Salto, Uruguay, to identify mosquito-producing containers, the spatial distribution of mosquitoes and the relationship between the different population indices of Aedes aegypti. On each of 312 premises visited, water-filled containers and immature Ae. aegypti mosquitoes were identified. The containers were counted and classified into six categories. Pupae per person and Stegomyia indices were calculated. Pupae per person were represented spatially. The number of each type of container and number of mosquitoes in each were analyzed and compared, and their spatial distribution was analyzed. No significant differences in the number of the different types of containers with mosquitoes or in the number of mosquitoes in each were found. The distribution of the containers with mosquito was random and the distribution of mosquitoes by type of container was aggregated or highly aggregated.

This study analyzes the demand and use of medical services in terms of age and sex for outpatient care and hospitalization provided to the 272,000 members of the Medical Association Assistance Center in Uruguay, a prepaid nonprofit insurance plan. Individual records were organized into annual usage by five-year age groups and reveal that use of services--consultations, drugs, and hospitalization--increases exponentially after the age of 50. Women utilize from 15% to 41% more services than men. The cost of services shows the same trend. For those over 84 years of age, this cost is US$598 per year, with an average institutional cost of US$166. The study also quantifies differences in risk by age and sex and draws conclusions regarding price and admission policies for new members of collective medical care institutions, which in July 1990 covered 51% of the Uruguayan population.

A new species of Scyphophyllidium inhabits Mustelus mento near La Paloma, Uruguay. It resembles Scyphophyllidium giganteum from the Atlantic Ocean and specimens identified as S. giganteum from California by having anapolytic strobilae 155-258 mm long, 250-300 craspedote proglottids, scoleces 1.2-1.4 mm wide, necks 34-41 mm long, immature and mature proglottids wider than long, gravid proglottids wider than long to longer than wide, genital pores averaging 28% of proglottid length from the anterior end, relatively flat ovaries with digitiform lobes reaching the lateralmost extent of the testicular field, vitellaria in 2 fields converging toward the proglottid midline, straight and short cirrus sacs, and postvaginal vas deferens. The bothridia of the new species have accessory bothridial suckers that are smaller than those of California specimens; European specimens reportedly lack accessory bothridial suckers. The new species possesses a uterine duct that joins the uterus at the level of the genital atrium and ventral osmoregulatory ducts medial rather than lateral to the dorsal ducts, an arrangement described for Californian but not European specimens. It differs from both European and Californian specimens by having longer cirri, more testes per proglottid, prominent scales covering the neck, and vaginae and uterine ducts coiled immediately preovarially. Pithophorus, Marsupiobothrium, and Scyphophyllidium may form a clade.

On two farms it was noted that after routine treatment with monepantel, fecal egg counts failed to drop. This was accompanied by lambs mortality due to Haemonchus contortus infection. The aim of this work was to evaluate the efficacy of monepantel to control gastrointestinal nematodes (GIN) in two sheep farms, in Uruguay. A Fecal Egg Count Reduction Test (FECRT) was subsequently performed at the Experimental Stations Glencoe of INIA Tacuarembó (Farm 1) and Sheep Unit of INIA La Estanzuela (Farm 2) using the World Association for the Advancement of Veterinary Parasitology guidelines. On Farm 1 the FECRT was performed using 6-8 month old Corriedale or Merino Dohne x Corriedale male lambs naturally infected with GIN. On day 0 pre-treatment, three groups of 15 lambs each were selected, blocked by fecal egg count level (FEC) and randomly assigned to one of the following: Group 0 = untreated control, Group 1 = treated with monepantel (Zolvix®, Novartis Animal Health Inc.) from stock previously purchased; Group 2 = treated with monepantel from stock provided by the supplier, at the recommended dose of 2.5 mg/kg of body weight. Fecal samples were collected directly from the rectum from each lamb on day 0 and on day 9 post-treatment. On Farm 2, the FECRT was conducted on a group of 8 month old male lambs Milchschaff x Finn. At this farm, 10 lambs were randomly allocated to be treated with monepantel (Group 1) and 10 lambs were randomly allocated to remain as untreated control (Group 0) using the same protocols as Farm 1. On farm 1 the FECR was 0.0% (95% CI = 0.0-49.0) and 42.0% (95% CI = 0.0-75.0) for Group 1 and Group 2 respectively. For Farm 2, the FECR was 82.1% (95% CI = 36.0-99.0). Haemonchus spp was the resistant genus. Poor effcicacy of monepantel in treating GIN parasites was demonstrated on both farms.

Stable isotopes (C, O, S) and mineralogical studies of the world-class amethyst-geode deposits of the Los Catalanes gemological district, Uruguay, constrain processes operative during mineral deposition. The mineralized basaltic andesites from the Cretaceous Paraná volcanic province are intensely altered to zeolites (clinoptilolite) and clay minerals. Variations in the δ18O values of silica minerals in geodes (chalcedony, quartz, and amethyst) are much larger and the values generally somewhat lower (21.2-31.5‰) in the Uruguayan deposits than in the Ametista do Sul area of southern Brazil. The range of δ34S values (-15.0 to -0.3‰) of altered basaltic rocks requires (in addition to sulfur of magmatic origin) the involvement of 34S-depleted sedimentary sulfur from bacterial sulfate reduction. The results delimit the mineralizing processes to a post-eruption environment characterized by low temperature and strong interaction of the lava flows with meteoric water.

Tracing redox processes during paleoclimatic changes in the Neoproterozoic: Stable chromium isotopic results from the Arroyo del Soldado Group (Ediacaran, Uruguay)

Positive δ13C carbonate values, combined with the occurrence of Fe-rich cherts (oxide-facies BIF) and organic-rich black shales within the late Ediacaran (ca. 580-560 Ma) Yerbal Fm. of the Arroyo del Soldato Group (Uruguay) are compatible with paleoclimatic models which postulate that enhanced bioproductivity due to higher availability of nutrient (P, N, Fe) was essential for controlling Neoproterozoic glaciations. Tracing of associated redox processes (f.e. linked to oxygenation of bottom waters in restricted basins) that might have been responsible for the deposition of Fe-rich cherts (BIFs) is therefore an important tool to better understand the seawater changes during cold-warm periods. Besides the traditionally used Fe and Mo isotopic systems, the redox-sensitive element Cr (Cr(III); Cr(IV)) and its stable isotopes offer another complementary system to trace paleo-redox processes. We have applied Cr stable isotope systematics to a sequence of samples from a late Ediacaran sedimentary sequence in Uruguay, using a 52Cr-54Cr double spike (Schoenberg et al., Chem..Geol., subm.). The middle Yerbal Fm. is dominated by organic-rich, black shales and black dolostones (δ53Cr = -0.05‰), followed by organic-rich cherts (δ53Cr = +1.83 - +4.49 ‰) and BIF (δ53Cr = -0.31 +0.90 ‰) gradually changing into Fe-bearing, organic-rich cherts and shales (δ53Cr = -0.28 - -0.01 ‰), and another sequence with BIF and organic-rich cherts topped by carbonates of the lower Polanco Fm. (δ53Cr = -0.17 to -0.27 ‰). The strongly positively fractionated Cr isotopic signatures in organic-rich and Fe-rich cherts in the Yerbal Fm. may point to significant oxidation processes either directly in the seawater column and/or during early diagenetic processes at the sediment-water interface. While these strongly positive δ53Cr values are the first to be reported from Neoproterozoic sedimentary sequence, the exact nature of the chemical process that produced these anomalies is not yet

Thyrotoxicosis is produced by excessive quantities of thyroid hormone. Its most common causes involve inflammation of the thyroid gland. Much more rarely, thyrotoxicosis is due to exogenous intake of thyroid hormones or iodide compounds. Few outbreaks are documented. In 2003 to early 2004, doctors in Minas, Uruguay noted a sharp increase in the incidence of thyrotoxicosis in a neighbourhood, with multiple cases within families. The objective of this study was to identify the source of the outbreak. A case-control study was conducted following surveillance and environmental inspection. Case patients were symptomatic residents of Minas with documented thyroid-stimulating hormone concentrations <0.1 microUI/ml or <0.49 microUI/ml and elevated free triiodothyronine or free thyroxine. Control subjects were frequency matched with case patients by barrio of residence and age. Case patients, control subjects and persons who prepared and purchased household food were interviewed using a standard questionnaire. Odds ratios adjusted (AOR) for age and gender were calculated by logistic regression in SUDAAN to account for neighbourhood and family clustering. Fifty-nine case patients aged 9-74 years (median 39 years) were identified. Of the 56 interviewed, 52% were women and 71% resided in one barrio. Case patients were more likely than control subjects to eat minced beef at least weekly and purchase it from Butcher A [AOR 6.1; 95% confidence interval (CI) 2.61-14.46], and were more likely to eat chorizo at least weekly and purchase it from Butcher B (AOR 11.6; 95% CI 1.30-102.27). One beef supplier selling meat cuts containing thyroid gland was identified. The most likely cause of this outbreak of thyrotoxicosis was consumption of minced beef and chorizo contaminated with thyroid gland. Tight regulation and oversight of slaughter, processing, and sales of meat and meat products are imperative for prevention of future outbreaks.

Beaches are social-ecological systems that provide several services improving human well-being. However, as one of the major coastal interfaces they are subject to plastic pollution, one of the most significant global environmental threats at present. For the first time for Uruguayan beaches, this study assessed and quantified the accumulation of plastic and microplastic debris on sandy beaches of the major touristic destination Punta del Este during the austral spring of 2013. Aiming to provide valuable information for decision-making, we performed a detailed analysis of plastic debris, their eventual transport pathways to the coast (from land and sea), and the associated persistent pollutants. The results indicated that the smallest size fractions (<20 mm) were the dominant size range, with fragments and resin pellets as types with the highest number of items. PAHs and PCBs were found in plastic debris, and their levels did not differ from baseline values reported for similar locations. The abundance of plastic debris was significantly and positively correlated with both the presence of possible land-based sources (e.g. storm-water drains, beach bars, beach access, car parking, and roads), and dissipative beach conditions. The analysis of coastal currents suggested some potential deposition areas along Punta del Este, and particularly for resin pellets, although modeling was not conclusive. From a local management point of view, the development and use of indices that allow predicting trends in the accumulation of plastic debris would be critically useful. The time dimension (e.g. seasonal) should also be considered for this threat, being crucial for locations such as Uruguay, where the use of beaches increases significantly during the summer. This first diagnosis aims to generate scientific baseline, necessary for improved management of plastic litter on beaches and their watersheds. Copyright © 2016 Elsevier Ltd. All rights reserved.

An integrated study of geological and geophysical data of the Río de la Plata region and its relation to the evolution of the Atlantic passive margin is herein described. This characterization is based on the available geological and geophysical information and on the correlation of the southern end of the best-known Santa Lucía Basin in Uruguay to the Salado Basin in Argentina, and their connection through the Quilmes Trough. Furthermore, a new Meso-Cenozoic depocenter is characterized and identified as Recalada Trough, subparallely aligned to the Quilmes Trough and separated from it by the Magdalena-Montevideo High. Both sedimentary fillings present ENE-WSW trending main axes and reach an average thickness of almost 2000 m. This suggests an evolution from a triple junction where interconnected extensional arms developed, which have had common Mesozoic tectosedimentary histories related to the early opening of the Atlantic Ocean. Based on the geophysical and geological evidence, the previously accepted existence in the Río de la Plata of a first-order structural feature along the international border between Argentina and Uruguay, associated to an ENE-WSW trending tectonic high, identified as Martín García, is unjustified. The tectonic evolution of the Atlantic margin in front of the Río de la Plata estuary is the consequence of a long deformation history starting in the Precambrian up to recent times. Each Precambrian, Paleozoic, Mesozoic and Cenozoic tectonic scenario adds different weak trends on the continental crust, which control the evolution of the sedimentary depocenters. The presence of these tectosedimentary records influence the bathymetric control of the Río de la Plata and the dynamics of the recent estuarine deposits. The Meso-Cenozoic sedimentary infill is estimated to comprise considerable ranges of sandstones and conglomerates associated with faulted blocks of the crystalline basement, with expected petrophysical conditions oscillating in

In many areas of Uruguay groundwater is the only source of water for human consumption and for industrial-agricultural economic activities. Traditionally considered as a safe source, groundwater is commonly used without any treatment. The Uruguayan law requires bacteriological (fecal) analysis for most water uses, but virological analyses are not mentioned in the legislation. In the Salto district, where groundwater is used for human consumption and for agricultural activities, bacterial contamination has been detected in several wells but no viruses analysis have been performed. The Republic University (UDELAR), with the support of the National Agency for Research and Innovation (ANII), is studying the incidence of virus and fecal bacteria in groundwater on an intensive agriculture area of the Salto district. An initial screening campaign of 44 wells was performed in which, besides total and fecal coliforms, rotavirus and adenovirus were detected. A subgroup of the screening wells (15) where selected for bimonthly sampling during a year. In accordance with literature results, single well data analysis shows that coliform and viral contamination can be considered as independent variables. However, when spatial data is integrated, coliform and viral contamination show linear correlation. In this work we present the survey results, we analyse the temporal incidence of variables like precipitation, temperature and chemical composition in well contamination and we discuss the value of coliforms as global indicator of viral contamination for the Salto aquifer.

2002-01-01

A total of 522 strains belonging to streptococci, enterococci and staphylococci isolated from sub-clinical and clinical cases of bovine mastitis from the west littoral region of Uruguay were analysed for their susceptibility to several antimicrobial agents. The susceptibility patterns were studied by agar disk diffusion methods (ADDM) and broth micro-dilution to determine the minimum inhibitory concentration (MIC). The concentration that inhibits 90% (MIC90) of the analysed strains reported in micrograms per millilitre, for Staphylococcus aureus were > 8, 8, ≤ 0.5, ≤ 4, ≤ 1, ≤ 0.5, > 64, ≤ 0.25, 0.5, ≤ 1 and ≤ 1 to penicillin, ampicillin, oxacillin, cephalotin, gentamicin, erythromycin, oxitetracycline, enrofloxacin, trimethoprim/sulfamethoxazole, neomycin, and clindamycin, respectively. Coagulase-negative staphylococci (CNS) had different values for penicillin (4) and ampicillin (2), while the other antimicrobial agents had the same MIC90 values as reported for S. aureus. The MIC90 values for streptococci were 0.12, 0.25, ≤ 4, 16, ≤ 0.25, 0.5, 0.25 for penicillin, ampicillin, cephalotin, gentamicin, erythromycin, oxytetracycline and trimethoprim-sulfamethoxazole, whereas MIC90 for enterococci were 4, 4, 4, ≤ 0.5, 2, > 8 for penicillin, ampicillin, gentamicin, erythromycin, oxytetracycline and trimethoprim-sulfamethoxazole, respectively. Of 336 strains of S. aureus, 160 (47.6%) were resistant to penicillin. For 41 CNS strains, 10 (27%) presented penicillin-resistance. All the streptococcal strains were susceptible to penicillin, while 3 (7%) of the 43 enteroccocal strains were resistant. Non significant statistical differences were found between the results obtained by ADDM and broth micro-dilution for classifying bacterial isolates as susceptible or resistant according to the National Committee of Clinical Laboratory Standards.

Governments, companies and individuals with financial capital to invest, are worldwide buying or renting land in developing or third world countries. Uruguay is a developing country whose economy is mainly based on agriculture. Since 2000 many foreigners started to invest in the Uruguayan agricultural sector and to practice intensive large-scale agriculture. The significant presence of foreigners in the country is proven by the fact that almost 360 000 ha out of the 500 000 ha forming the study area were managed by foreigners in 2012. Nowadays farmers have abandoned the traditional crop rotation plan that included pasture to produce grain for export, and transgenic soya (soya RR) became the main crop planted by both foreigners and locals. Besides the high soil erosion rates related to having soya as main crop, planting soya implies the use of glyphosate, a broad-spectrum systemic herbicide leading to important environmental impacts. It is commonly said that foreigners investing in poor countries are exploiting the local natural resources aiming to get the highest possible profit from them. Is this a valid assumption in Uruguay? The purpose of this study was to compare the land management style of foreign and local farmers and to relate it to the soil erosion occurring in the study area. The land tenure (rented or owned fields) and the type of farmer interviewed ("individual farmer" equivalent to L.L.C. or "anonymous society" equivalent to P.L.C.) were taken into consideration during the analysis. Based on what stated by the farmers interviewed, the soil erosion simulations considered the seven most popular crop rotation plans on rented and owned fields, three ideals crop rotation plans, the application of no mitigation measures, and the construction of terraces and conservation buffers. Depending on the crop rotation plan, soils characterized by slope gradients higher than 2 resulted in soil erosion rates higher than the 7 ton/ha/year allowed by law. The highest

We describe the isolation and characterization of alfalfa-nodulating rhizobia from acid soils of different locations in Central Argentina and Uruguay. A collection of 465 isolates was assembled, and the rhizobia were characterized for acid tolerance. Growth tests revealed the existence of 15 acid-tolerant (AT) isolates which were able to grow at pH 5.0 and formed nodules in alfalfa with a low rate of nitrogen fixation. Analysis of those isolates, including partial sequencing of the genes encoding 16S rRNA and genomic PCR-fingerprinting with MBOREP1 and BOXC1 primers, demonstrated that the new isolates share a genetic background closely related to that of the previously reported Rhizobium sp. Or191 recovered from an acid soil in Oregon (B. D. Eardly, J. P. Young, and R. K. Selander, Appl. Environ. Microbiol. 58:1809–1815, 1992). Growth curves, melanin production, temperature tolerance, and megaplasmid profiles of the AT isolates were all coincident with these characteristics in strain Or191. In addition to the ability of all of these strains to nodulate alfalfa (Medicago sativa) inefficiently, the AT isolates also nodulated the common bean and Leucaena leucocephala, showing an extended host range for nodulation of legumes. In alfalfa, the time course of nodule formation by the AT isolate LPU 83 showed a continued nodulation restricted to the emerging secondary roots, which was probably related to the low rate of nitrogen fixation by the largely ineffective nodules. Results demonstrate the complexity of the rhizobial populations present in the acidic soils represented by a main group of N2-fixing rhizobia and a second group of ineffective and less-predominant isolates related to the AT strain Or191.

The aim of this study was to assess the prevalence, extent, severity, intraoral distribution and risk indicators for erosive tooth wear (ETW) among 12-year-old schoolchildren from Montevideo, Uruguay. A population-based, cross-sectional survey was conducted using a representative sample of 1,136 12-year-old schoolchildren attending public and private schools. Parents answered questions on socioeconomic status and general health. Schoolchildren answered questions on dietary and oral hygiene habits. Two calibrated examiners recorded ETW on permanent teeth according to the Basic Erosive Wear Examination (BEWE) score system. Logistic regression models were performed to assess the association between the predictor variables and the prevalence of ETW (overall and severe ETW). Odds ratios (OR) and the respective 95% confidence intervals (CI) were estimated. The prevalence of ETW was 52.9%, being mild erosion (BEWE = 1) in the vast majority of cases (48.5%). Severe erosion (BEWE ≥2) was detected in 4.4% of schoolchildren. The overall prevalence of ETW differed significantly between categories of gender and socioeconomic status, but only between gender in the severe ETW analysis. The overall extent of ETW was significantly different between categories of gender, socioeconomic status, and swish before swallow. The extent of severe ETW differed between categories of swish before swallow and brushing frequency. In the logistic regression analysis, no association was found between the studied variables and the overall prevalence of ETW. Males were more likely to have severe ETW than females (OR = 3.22, 95% CI = 1.50-6.89). ETW may be considered a public health problem among 12-year-old-Uruguayan schoolchildren.

In humans, a person's chronotype depends on environmental cues and on individual characteristics, with late chronotypes prevailing in youth. Social jetlag (SJL), the misalignment between an individual׳s biological clock and social time, is higher in late chronotypes. Strong SJL is expected in Uruguayan university students with morning class schedules and very late entertainment activities. Sleep disorders have been reported in Antarctic inhabitants, that might be a response to the extreme environment or to the strictness of Antarctic life. We evaluated, for the first time in Uruguay, the chronotypes and SJL of 17 undergraduate students of the First Uruguayan Summer School on Antarctic Research, using Munich Chronotype Questionnaire (MCTQ) and sleep logs (SL) recorded during 3 phases: pre-Antarctic, Antarctic, and post-Antarctic. The midsleep point of free days corrected for sleep debt on work days (MSFsc,) was used as proxy of individuals' chronotype, whose values (around 6 a.m.) are the latest ever reported. We found a SJL of around 2 h in average, which correlated positively with MSFsc, confirming that late chronotypes generate a higher sleep debt during weekdays. Midsleep point and sleep duration significantly decreased between pre-Antarctic and Antarctic phases, and sleep duration rebounded to significant higher values in the post-Antarctic phase. Waking time, but not sleep onset time, significantly varied among phases. This evidence suggests that sleep schedules more likely depended on the social agenda than on the environmental light-dark shifts. High motivation of students towards Antarctic activities likely induced a subjective perception of welfare non-dependent on sleep duration.

Quantifiable impact on poverty in Trinidad And Tobago of the Uruguay Round Agreement On Agriculture.

The agreement on agriculture and the World Trade Organization were major outcomes of the 1986-1994 Uruguay Round (UR) negotiations within the General Agreement on Tariffs and Trade (GATT). The measures under the UR were predicted to increase poverty in developing countries, a serious cause for concern since poverty alleviation is a major goal of developing countries. Thus this paper simulated the impact on poverty of the UR for a net food importing country, Trinidad and Tobago. The objectives of the study were to determine the changes in poverty levels in Trinidad and Tobago that we expected would result from changes in the price levels of food commodities after the removal of trade protection following the UR, and to examine recent trends in poverty in Trinidad and Tobago and the prices of major agricultural exports from the United States, its principal trading partner. A regression model (poverty model) was used to determine the relationship between poverty levels and the prices of sensitive imported food commodities (SIFCs) and other key economic variables. Impact models were used to project changes in world market prices of the SIFCs due to the UR, and these price changes were used to predict changes in poverty in Trinidad and Tobago. The results showed a positive elasticity between poverty and the prices of SIFCs. The study also predicted that the average projected increase in price levels of the SIFCs of less than 9% by the year 2000 would cause an increase in poverty in Trinidad and Tobago of less than 4%. There has been, in fact, a small decline in poverty in Trinidad and Tobago since 1996. The prices of major agricultural exports from the United States have also been falling since 1995. Thus, so far the UR has had no perceptible effects in increasing the prices of food exports from the United States. Also, so far the UR has had no perceptible effect on the poverty level in Trinidad and Tobago.

This paper develops the methodological principles of pooled analysis design, using it to study situations of vulnerability among drug users at a regional level. Data from thirteen cross-sectional studies carried out in Argentina, Brazil and Uruguay between 1998 and 2004 were integrated. A critical review of the concept of data matrix which identifies four structural components, allowed us to: define the units of analysis spanning the different original populations; identify a core of common variables (social and demographic characteristics, drug use, sexual practices, serology of blood-borne and sexually transmitted diseases) with their respective values; examine the indicators, dimensions and procedures used to measure the variables; and establish their compatibility with a thematic and comparative analysis of data collection tools. The main result was a new data matrix with 3,534 cases. Multidisciplinary collaboration between teams and institutions from the three countries made it possible to maximize the available sources in order to analyze characteristics of the local contexts and of the overall regional.

Preliminary AMS Study in Cretaceous Igneous Rocks of Valle Chico Complex, Uruguay: Statistical Determination of Magnetic Susceptibility

Barcelona, H.; Mena, M.; Sanchez-Bettucci, L.

2009-05-01

The Valle Chico Complex, at southeast Uruguay, is related Paraná-Etendeka Province. The study involved basaltic lavas, quarz-syenites, and rhyolitic and trachytic dikes. Samples were taken from 18 sites and the AMS of 250 specimens was analyzed. The AMS is modeled by a second order tensor K and it graphical representation is a symmetric ellipsoid. The axes relations determine parameters which describe different properties like shape, lineation, and foliation, degree of anisotropy and bulk magnetic susceptibility. Under this perspective, one lava, dike, or igneous body can be considered a mosaic of magnetic susceptibility domains (MSD). The DSM is an area with specific degree of homogeneity in the distribution of parameters values and cinematic conditions. An average tensor would weigh only one MSD, but if the site is a mosaic, subsets of specimens with similar parameters can be created. Hypothesis tests can be used to establish parameter similarities. It would be suitable considered as a MSD the subsets with statistically significant differences in at least one of its means parameters, and therefore, be treated independently. Once defined the MSDs the tensor analysis continues. The basalt-andesitic lavas present MSD with an NNW magnetic foliation, dipping 10. The K1 are sub-horizontal, oriented E-W and reprsent the magmatic flow direction. The quartz-syenites show a variable magnetic fabric or prolate ellipsoids mayor axes dispose parallel to the flow direction (10 to the SSE). Deformed syenites show N300/11 magnetic foliation, consistent with the trend of fractures. The K1 is subvertical. The MSD defined in rhyolitic dikes have magnetic foliations consistent with the structural trend. The trachytic dikes show an important indetermination in the magnetic response. However, a 62/N90 magnetic lineation was defined. The MSDs obtained are consistent with the geological structures and contribute to the knowledge of the tectonic, magmatic and kinematic events.

This research is focused on development of remote sensing methods to assess surface water pollution issues, particularly in multipurpose reservoirs. Three case study applications are presented to comparatively analyze remote sensing techniquesforo detection of nutrient related pollution, i.e., Nitrogen, Phosphorus, Chlorophyll, as this is a major water quality issue that has been identified in terms of pollution of major water sources around the country. This assessment will contribute to a better understanding of options for nutrient remote sensing capabilities and needs and assist water agencies in identifying the appropriate remote sensing tools and devise an application strategy to provide information needed to support decision-making regarding the targeting and monitoring of nutrient pollution prevention and mitigation measures. A detailed review of the water quality data available from ground based measurements was conducted in order to determine their suitability for a case study application of remote sensing. In the first case study, the Valle de Bravo reservoir in Mexico City reservoir offers a larger database of water quality which may be used to better calibrate and validate the algorithms required to obtain water quality data from remote sensing raw data. In the second case study application, the relatively data scarce Lake Toba in Indonesia can be useful to illustrate the value added of remote sensing data in locations where water quality data is deficient or inexistent. The third case study in the Paso Severino reservoir in Uruguay offers a combination of data scarcity and persistent development of harmful algae blooms. Landsat-TM data was obteined for the 3 study sites and algorithms for three key water quality parameters that are related to nutrient pollution: Chlorophyll-a, Total Nitrogen, and Total Phosphorus were calibrated and validated at the study sites. The three case study applications were developed into capacity building/training workshops

Usbnd Pb detrital zircon ages from some Neoproterozoic successions of Uruguay: Provenance, stratigraphy and tectonic evolution

The Neoproterozoic volcano-sedimentary successions of Uruguay have been the subject of several sedimentologic, chrono-stratigraphic and tectonic interpretation studies. Recent studies have shown, however, that the stratigraphy, age and tectonic evolution of these units remain uncertain. Here we use new Usbnd Pb detrital zircon ages, combined with previously published geochronologic and stratigraphic data in order to provide more precise temporal constraints on their depositional age and to establish a more solid framework for the stratigraphic and tectonic evolution of these units. The sequence of events begins with a period of tectonic quiescence and deposition of extensive mixed siliciclastic-carbonate sedimentary successions. This is followed by the development of small fault-bounded siliciclastic and volcaniclastic basins and the emplacement of voluminous granites associated with episodic terrane accretion. According to our model, the Arroyo del Soldado Group and the Piedras de Afilar Formation were deposited sometime between ∼1000 and 650 Ma, and represent passive continental margin deposits of the Nico Pérez and Piedra Alta terranes, respectively. In contrast, the Ediacaran San Carlos (<552 ± 3 Ma) and Barriga Negra (<581 ± 6 Ma) formations, and the Maldonado Group (<580-566 Ma) were deposited in tectonically active basins developed on the Nico Pérez and Cuchilla Dionisio terranes, and the herein defined Edén Terrane. The Edén and the Nico Pérez terranes likely accreted at ∼650-620 Ma (Edén Accretionary Event), followed by their accretion to the Piedra Alta Terrane at ∼620-600 Ma (Piedra Alta Accretionary Event), and culminating with the accretion of the Cuchilla Dionisio Terrane at ∼600-560 Ma (Cuchilla Dionisio Accretionary Event). Although existing models consider all the Ediacaran granites as a result of a single orogenic event, recently published age constraints point to the existence of at least two distinct stages of granite generation

El artículo de San Mauro y cols. profundiza en un tema de interés prioritario como es el estudio de los hábitos de ingesta de fluidos en personas de cuatro países: España, Portugal, México y Uruguay, para analizar si se cumplen (y si se conocen) las pautas de hidratación marcadas como adecuadas por organismos oficiales y, en concreto, por la EFSA. Es indudable la importancia de una correcta hidratación pues mientras que se puede vivir meses, o años, con una alimentación incorrecta, la deshidratación puede llevar a la muerte en un escaso periodo de tiempo. Por otra parte, un aporte ligeramente insuficiente de fluidos perjudica la salud, capacidad funcional y calidad de vida del individuo, por lo que debe ser evitada. Incluso algunos estudios encuentran hábitos y estilo de vida menos saludables en individuos con menor consumo de fluidos y pautas de hidratación más incorrectas.

Mesoproterozoic evolution of the Río de la Plata Craton in Uruguay: at the heart of Rodinia?

Mesoproterozoic volcanosedimentary units and tectonic events occurring in the Río de la Plata Craton (RPC) are reviewed. A belt consisting of volcanosedimentary successions exhibiting greenschist-facies metamorphism is exposed in the eastern RPC (Nico Pérez Terrane) in Uruguay. The Parque UTE Group consists of basic volcanics and gabbros at the base (1,492 ± 4 Ma, U-Pb on zircon), carbonates in its middle part and interbedded carbonates, shales and acid volcanics (1,429 ± 21 Ma, U-Pb on zircon) at the top. The Mina Verdún Group is made up of rhyolites and acid pyroclastics at its base and top, and Conophyton-bearing limestones and massive dolostones in the middle. A U-Pb LA-ICP MS zircon age of 1,433 ± 6 Ma is reported here for lapilli-tuffs at the base of the Mina Verdún Group (Cerro de las Víboras Formation). This age shows that the Mina Verdún Group immediately postdates the Parque UTE Group, a fact supported by carbon isotope chemostratigraphy. Both units were deformed and metamorphosed between 1.25 and 1.20 Ga, as shown by K-Ar and Ar-Ar ages. This tectonic event affected most of the RPC and led to the accretion of the Nico Pérez Terrane to the remainder of the RPC along the Sarandí del Yí megashear. We report a U-Pb LA-ICP MS zircon age (upper intercept) of 3,096 ± 45 Ma for metatonalites of the La China Complex (Nico Pérez Terrane), which yield a lower intercept age of 1,252 Ma. A proto-Andean, Mesoproterozoic belt is envisaged to account for abundant Mesoproterozoic detrital zircon ages occurring in Ediacaran sandstones of the RPC. If the RPC is fringed at both sides by Mesoproterozoic, Grenville-aged belts it is likely that it occupied a rather central position in Rodinia. A possible location between Laurentia and the Kalahari Craton, and to the south of Amazonia, is suggested.

The La Plata Basin, the fifth largest basin in the world and second only to the Amazon in South America, is 3.6 million km2 and covers portions of 5 countries: Argentina, Brazil, Bolivia, Paraguay, and Uruguay. Sub-basins include the Bermejo, Paraná, Paraguay, Pilcomayo, and Uruguay. Major rivers of the basin are the Paraguay, the Uruguay and the Paraná. Streamflows in the LPB have been above normal in the last decades, e.g. the mean flow in the Paraná river during the 1971-1994 period was 34% higher than the mean flow during the 1931-1970 period. A similar analysis carried out on the precipitation records for the La Plata basin showed only a 14% increase during the same periods for the Upper Paraná basin and a 20% increase for the Uruguay basin. In this paper it is postulated that the increase in the streamflows, not explained by precipitation increases, is due to the changes in cultivation patterns in the upper basins of the Paraná and Uruguay. Particularly, the substitution of coffee plantations for annual crops, mainly soybeans, has produced a change in the infiltration patterns that influenced the discharges.

Giant geodes (up to 4 m long) in the massive central portions of altered basalt lavas from the Paraná Magmatic Province, southern Brazil and Uruguay, form a world-class source of amethyst and agate. Although the origin of the cavities has been ascribed to degassing of the lava at > 1150 °C, field evidence is conclusive that the giant amethyst-agate-filled geodes were formed by hydrothermal processes at low temperatures. We propose an epigenetic and hydrothermal model for the origin of giant geodes. This model includes hydrothermal brecciation during an early brittle stage and the late formation of the cavities (geodes). In the brittle stage an overpressured aqueous fluid affected the basalt in a P, T field delimited by temperatures between 100 and 150 °C and vapor pressures between 1.2 and 5.5 bar. The fluids were capable of lifting the roof and fracturing the host rock along new subhorizontal and subvertical fractures and breccias in the massive lava. The formation of these structures occurred at shallow depths, unit-by-unit. To open the cavities, dissolution of the now altered basalt to clay minerals is necessary. The process is closely linked to the highest alteration grade of mineralized lavas in Los Catalanes gemological district. Dissolution processes are observed in micrometer-scale in the studied basalts. The primary mineralogy, consisting of labradorite (± andesine) +augite + pigeonite + mesostasis (K-rich), was altered during the interaction of large volumes of hot aqueous fluid with the rock. The alteration of pigeonite and its replacement by smectite is observed around the cavities, followed by the precipitation of amorphous silica and microcrystalline quartz in clay-rich sites. Associated zeolites (heulandite + clinoptilolite) fill the newly formed cavities in progressive stages of hydrothermal alteration. Our data indicate that the temperatures were less than 200 °C and probably less than 150 °C; cavity formation occurred after alteration of the

El capital social supone importantes inversiones materiales, simbólicas y de esfuerzos. Conocer el capital social de una comunidad puede facilitar la comprensión del beneficio de las relaciones comunitarias para la promoción de salud. Con el objetivo de reconocer los componentes del capital social de padres de escolares atendiendo una escuela en una zona vulnerable de la ciudad de Córdoba, Argentina, indagamos a través de grupos focales acerca de elementos esenciales del capital social. La asintonía socio-cultural entre los pobladores originarios y los reubicados, la estigmatización policial y el clientelismo político han generado desconfianza del uno hacia el otro en diferentes aspectos convivenciales, siendo la familia la única red de apoyo. La escuela se reconoce como espacio adonde la gente espontáneamente se organiza para invertir en redes sociales, presentándose así con potencialidad para la promoción de conductas saludables, por el lugar simbólico que ocupa para los padres.

The Punta del Este Terrane (eastern Uruguay) lies in a complex Neoproterozoic (Brasiliano/Pan-African) orogenic zone considered to contain a suture between South American terranes to the west of Major Gercino-Sierra Ballena Suture Zone and eastern African affinities terranes. Zircon cores from Punta del Este Terrane basement orthogneisses have U-Pb ages of ca. 1,000 Ma, which indicate an lineage with the Namaqua Belt in Southwestern Africa. U-Pb zircon ages also provide the following information on the Punta del Este terrane: the orthogneisses containing the ca. 1,000 Ma inheritance formed at ca. 750 Ma; in contrast to the related terranes now in Africa, reworking of the Punta del Este Terrane during Brasiliano/Pan-African orogenesis was very intense, reaching granulite facies at ca. 640 Ma. The termination of the Brasiliano/Pan-African orogeny is marked by formation of acid volcanic and volcanoclastic rocks at ca. 570 Ma (Sierra de Aguirre Formation), formation of late sedimentary basins (San Carlos Formation) and then intrusion at ca. 535 Ma of post-tectonic granitoids (Santa Teresa and José Ignacio batholiths). The Punta del Este Terrane and unrelated western terranes represented by the Dom Feliciano Belt and the Río de La Plata Craton were in their present positions by ca. 535 Ma.

Exposure to secondhand smoke (SHS) from burning tobacco products causes disease and premature death among non-smoking adults and children. The objective of this study was to determine the nature, extent and demographic correlates of SHS exposure among adults in low- and middle-income countries with a high burden of tobacco use. Data were obtained from the Global Adult Tobacco Survey (GATS), a nationally representative household survey of individuals 15 years of age or older. Interviews were conducted during 2008-2010 in Bangladesh, Brazil, China, Egypt, India, Mexico, the Philippines, Poland, Russia, Thailand, Turkey, Ukraine, Uruguay and Vietnam. Descriptive statistics were used to determine the prevalence and correlates of SHS exposure in homes, workplaces, government buildings, restaurants, public transportation and healthcare facilities. Exposure to SHS in the home ranged from 17.3% (Mexico) to 73.1% (Vietnam). Among those who work in an indoor area outside the home, SHS exposure in the workplace ranged from 16.5% (Uruguay) to 63.3% (China). Exposure to SHS ranged from 6.9% (Uruguay) to 72.7% (Egypt) in government buildings, 4.4% (Uruguay) to 88.5% (China) in restaurants, 5.4% (Uruguay) to 79.6% (Egypt) on public transportation, and 3.8% (Uruguay) to 49.2% (Egypt) in healthcare facilities. A large proportion of adults living in low- and middle-income countries are exposed to SHS in their homes, workplaces, and other public places. Countries can enact and enforce legislation requiring 100% smoke-free public places and workplaces, and can also conduct educational initiatives to reduce SHS exposure in homes.

The objective of the present study was to characterise the mechanisms underlying quinolone and oxyimino-cephalosporin resistance in a Citrobacter freundii clinical isolate obtained from the ICU in Uruguay's University Hospital. Citrobacter freundii strain CF638 was isolated from a urine culture. Identification and susceptibility testing were performed using the VITEK ® 2 system, and MIC determination and disc diffusion assay, respectively. Resistance genes and mobile genetic elements were identified, by PCR and sequencing. Plasmid transfer was assessed by conjugation; plasmid, size was estimated by treatment with S1 and PFGE. Plasmid incompatibility, group and toxin-antitoxin systems were sought by PCR. Strain CF638 showed a multi-drug resistant profile, including, resistance to carbapenemes and quinolones. Transconjugant TcCF638, harbouring a ∼200 kb IncA/C plasmid, also showed resistance to all β-lactams, (except for aztreonam), and diminished susceptibility to ciprofloxacin. PCR, assays were positive for bla NDM-1 and qnrVC in CF638 and TcCF638. Two different class 1 integrons were detected, In127 and In907. In127, featured the genetic array: aadA2-ltr2. Conversely, complex In907 featured, two variable regions (VR); VR-1 consisted of aadB-bla OXA-10 -aadA1cc, whereas, VR-2, featured a gene qnrVC6 108 bp downstream from the ISCR1 and 45 bp, upstream from the qacEΔ1. Expression of qnrVC6 would be on account of a, putative promoter region, detected using the Neural Network Promoter, Prediction program. To the best of our knowledge this constitutes the first report of a qnrVC gene within a complex class 1 integron, and the first report as well of the occurrence of such gene in an NDM-1-producing enterobacterial clinical isolate.

In the ongoing GEnotipo, Fenotipo y Ambiente de la HiperTensión Arterial en UruguaY (GEFA-HT-UY) study, we applied standardized epidemiological methods to determine complex phenotypes including blood pressure (BP). In this report, we present the quality control of the conventionally measured BP. Three trained observers measured BP five times consecutively in the seated position at each of two home visits and one clinic visit according to the guidelines of the European Society of Hypertension. On 1 December 2013, 4379 single BP readings in 170 participants were available for analysis. Fewer BP readings than the five planned per contact occurred only at one home visit. Among observers, the frequency of identical consecutive readings for systolic or diastolic BP varied from 0 to 4.2%. The occurrence of odd readings ranged from 0.1 to 0.6%. Only 21.6% of the systolic and diastolic BP readings ended on zero (expected 20%). At home visits, there was a progressive decline in BP from the first to the fifth reading. The average of the five BP readings also decreased from the first to the second home visit (-5.63/-2.34 mmHg). Our study highlighted the necessity to implement a stringent quality control of the conventionally measured BP. The procedures set up in the GEFA-HT-UY study are resulting in a well-defined BP phenotype, which is consistent with that in other population studies.

Abstract. To contribute to the prevention of dengue, chikungunya, and Zika, a process of scaling up an innovative intervention to reduce Aedes aegypti habitats, was carried out in the city of Salto (Uruguay) based on a transdisciplinary analysis of the eco-bio-social determinants. The intervention in one-third of the city included the distributions of plastic bags for all households to collect all discarded water containers that were recollected by the Ministry of Health and the Municipality vector control services. The results were evaluated in 20 randomly assigned clusters of 100 households each, in the intervention and control arm. The intervention resulted in a significantly larger decrease in the number of pupae per person index (as a proxy for adult vector abundance) than the corresponding decrease in the control areas (both areas decreased by winter effects). The reduction of intervention costs (“incremental costs”) in relation to routine vector control activities was 46%. Community participation increased the collaboration with the intervention program considerably (from 48% of bags handed back out of the total of bags delivered to 59% of bags handed back). Although the costs increased by 26% compared with intervention without community participation, the acceptability of actions by residents increased from 66% to 78%. PMID:28820690

: Venous thromboembolism remains as one of the leading causes of maternal death. Prevention of venous thromboembolism in the obstetric population is challenging as recommendations for prophylaxis have low grade of evidence. Risk factors and prophylaxis guidelines have been highlighted by Royal College of Obstetricians and Gynaecologists. In 2014, we developed a written alert following this guidelines to guide thromboprophylaxis. The aim of this study is to assess recommendations compliance. This study was conducted at University-Hospital in Uruguay from January 2014 to December 2016. A total of 1035 women were enrolled and stratified in high, intermediate or low risk based on Royal College of Obstetricians and Gynaecologists guidelines. Thromboprophylaxis was recommended for women at intermediate and high risk. Women were followed up to assess symptomatic thromboembolism or haemorrhagic complications. A total of 309 were pregnant and 731 puerperal. Median age was 24 (19-29) years old. Of them, 3.0% (n = 31) were at high risk and 35.4% (n = 366) at intermediate risk. All high-risk women received prophylaxis with low-molecular-weight heparin. Of the 366 intermediate-risk women, 52.7% received prophylaxis. Venous thromboembolism was developed in only one woman of the intermediate group, who had received prophylaxis. Bleeding complications were not observed. Awareness of the thrombotic risk, as conferred by an easy and suitable risk assessment, has the potential to improve venous thromboembolism prophylaxis in pregnant and puerperal women. We have a good guidelines compliance with the written alert in the high-risk women group. However, we have to improve low-molecular-weight heparin indication in intermediate-risk group, especially in postcaesarean women.

Aedes aegypti from temperate regions of South America are highly competent to transmit dengue virus

PubMed Central

2013-01-01

Background Aedes aegypti is extensively spread throughout South America where it has been responsible for large dengue epidemics during the last decades. Intriguingly, dengue transmission has not been reported in Uruguay and is essentially prevalent in subtropical northern Argentina which borders Uruguay. Methods We assessed vector competence for dengue virus (DENV) of Ae. aegypti populations collected in subtropical Argentina (Corrientes) as well as temperate Uruguay (Salto) and Argentina (Buenos Aires) in 2012 using experimental oral infections with DENV-2. Mosquitoes were incubated at 28°C and examined at 14 and 21 days p.i. to access viral dissemination and transmission. Batches of the Buenos Aires mosquitoes were also incubated at 15°C and 20°C. Results Although mosquitoes from temperate Uruguay and Argentina were competent to transmit DENV, those from subtropical Argentina were more susceptible, displaying the highest virus titters in the head and presenting the highest dissemination of infection and transmission efficiency rates when incubated at 28°C. Interestingly, infectious viral particles could be detected in saliva of mosquitoes from Buenos Aires exposed to 15°C and 20°C. Conclusions There is a potential risk of establishing DENV transmission in Uruguay and for the spread of dengue outbreaks to other parts of subtropical and temperate Argentina, notably during spring and summer periods.

The goals of this study were to identify the proportion of early adolescents in southern South America who were injured in the past year, to identify risk behaviours and other exposures associated with injuries, and to evaluate the most common types and causes of injury in this population. We used complex samples analysis to examine cross-sectional data from more than 35,000 students from all four countries in South America that participated in the Global School-based Student Health Survey (GSHS) in 2012-2013. The proportion of students reporting at least one injury in the past year that required medical treatment or caused at least one full day of missed school or usual activities was 27.1% in Argentina, 29.5% in Uruguay, 30.9% in Chile, and 36.8% in Bolivia. Significantly more boys than girls reported injuries. Injured students were more likely than non-injured students to report anxiety-induced insomnia, being physically attacked, being in a physical fight, and being lonely in the past year, and they were also more likely to report being bullied, using tobacco, drinking alcohol, and missing school in the past month. For both boys and girls, the most common type of injury reported was a broken bone or dislocated joint and the most common injury cause was the student falling. However, most students were not able to provide a specific answer to either question. The GSHS has been conducted in 100 low- and middle-income countries and territories around the world, and new waves of data collection are currently being planned and implemented. The utility of the injury data from the GSHS would be improved if the injury type and cause response items were updated to better capture information about self-harm, sports injuries, and other statistics that will provide a stronger foundation for evidence-based injury prevention interventions in adolescent populations.

Background Little research has been done to examine whether smokers switch to illegal or roll-your-own (RYO) cigarettes in response to a change in their relative price. Objective This paper explores how relative prices between three cigarette forms (manufactured legal, manufactured illegal, and RYO cigarettes) are associated with the choice of one form over another after controlling for covariates, including sociodemographic characteristics, smokers’ exposure to anti-smoking messaging, health warning labels, and tobacco marketing. Methods Generalized estimating equations (GEE) were employed to analyse the association between the price ratio of two different cigarette forms and the usage of one form over the other. Findings A 10% increase in the relative price ratio of legal to RYO cigarettes is associated with 4.6% increase in the probability of consuming RYO over manufactured legal cigarettes (P≤0.05). In addition, more exposure to anti-smoking messaging is associated with lower odds of choosing RYO over manufactured legal cigarettes (P≤0.05). Non-significant associations exist between the manufactured illegal to legal cigarette price ratios and choosing manufactured illegal cigarettes, suggesting that smokers do not switch to manufactured illegal cigarettes as prices of legal ones increase. However, these non-significant findings may be due to lack of variation in the price ratio measures. In order to improve the effectiveness of increased taxes and prices in reducing smoking, policy makers need to narrow price variability in the tobacco market. Moreover, increasing anti-smoking messaging reduces tax avoidance in the form of switching to cheaper RYO cigarettes in Uruguay. PMID:25740084

En este trabajo presentamos un nuevo análisis orbital de LSS~3074, junto con tipos espectrales y velocidades radiales de estrellas que podrían constituir con ella una nueva asociación OB. La estrella O4f LSS3074 fue descubierta como binaria espectroscópica de corto período y líneas dobles por Morrell & Niemela (1990, ASP Conf. Ser. 7, 57). Posteriormente, Haefner et~al.(1994, IBVS 3969) encontraron variaciones fotométricas, estimando una inclinación orbital entre 50o y 55o. Teniendo en cuenta la importancia de obtener valores empíricos para las masas de estrellas O tempranas, y considerando la gran dispersión existente entre los valores observados y su discrepancia con los predichos por los modelos teóricos, hemos obtenido nuevas observaciones espectroscópicas de este sistema, con el propósito de mejorar los elementos orbitales derivados en la solución preliminar. Además, como las estrellas O tempranas suelen formar parte de cúmulos y asociaciones OB, hemos llevado a cabo una investigación espectroscópica de varias estrellas tempranas que podrían estar físicamente relacionadas con LSS~3074.

Exhumed subglacial landscape in Uruguay: Erosional landforms, depositional environments, and paleo-ice flow in the context of the late Paleozoic Gondwanan glaciation

NASA Astrophysics Data System (ADS)

2018-07-01

A well-exposed glacial surface sculpted on Precambrian crystalline basement rocks occurs below the glacial succession of the San Gregorio Formation on the eastern border of the Chaco-Parana Basin in Uruguay and was formed in the context of the late Paleozoic Gondwana Ice Age. On the glacial surface are asymmetric parallel streamlined bedrock landforms interpreted as whalebacks. The downglacier (lee-side) faces of the whalebacks have gentle slopes dipping NNW with striated and sometimes polished surfaces on crystalline rocks. These landforms are covered by 10-100-cm-thick layers of tillites and shear-laminated siltstones, suggesting glacial abrasion produced mainly by subglacial till sliding. The subglacial facies are ice-molded, and exhibit meso-scale glacial lineations such as ridges and grooves up to 30 m long and 30 cm deep. The subglacial association is directly overlain by proglacial fine-grained facies (rhythmites) with dropstones indicating a subaqueous depositional environment following ice-margin retreat. The fine-grained facies are erosively cut by a succession of sandstones with wave-generated stratification resting on a basal conglomerate. Intraformational striated surfaces, NNE-oriented, were found on four distinct bedding planes within the sandstone package and interpreted as ice keel scour marks produced by floating ice. The San Gregorio deposits are partially confined in a wide and shallow subglacial trough and the stratigraphic succession is interpreted as the record of a glacial advance-retreat cycle comparable to deglacial sequences from other late Paleozoic localities. The paleo-ice flow to the NNW indicated by subglacial lineations is parallel to that verified in the southernmost Paraná Basin located north of the study area, suggesting a paleogeographic scenario in which glaciers advanced northward into a glaciomarine environment. The proposed palaeogeography does not confirm the previous hypothesis of an ice center on the Sul

This study compares immigrant (i.e., foreigner) with non-immigrant (i.e., local/native) HIV-related risk behaviors among female sex workers (FSW) in South America. A total of 1,845 FSW were enrolled in Argentina, Bolivia, Ecuador, and Uruguay. According to their nationality, 10.1% of participants were immigrant FSW. Immigrant FSW were more likely to be younger in Argentina; to work in a disco/bar in Bolivia; to be single and use illegal drugs in Ecuador; and to work in a brothel, consume alcohol, and have sex with foreign clients in Uruguay. HIV-related sexual and drug use behaviors were more common among immigrant FSW in Bolivia, Ecuador, and Uruguay. Country-specific HIV/STI prevention and control programs should be developed for immigrant FSW populations in South America.

Simple Summary GHGs emissions are relevant in evaluating environmental impact of farming systems. Methane (CH4) produced by enteric fermentation accounts for half of all anthropogenic emissions of GHGs in Uruguay, where ruminant production is based on year round grazing of forages. Here we compared milk production and CH4 emissions by dairy cows grazing two contrasting mixed pastures (rich in legumes or rich in grasses) using the SF6 tracer technique adapted to collect breath samples over 5-days periods. There were no differences in milk or CH4 production between the contrasting pastures, probably because of the high herbage allowance that enabled selective grazing by cows. Abstract Understanding the impact of changing pasture composition on reducing emissions of GHGs in dairy grazing systems is an important issue to mitigate climate change. The aim of this study was to estimate daily CH4 emissions of dairy cows grazing two mixed pastures with contrasting composition of grasses and legumes: L pasture with 60% legumes on Dry Matter (DM) basis and G pasture with 75% grasses on DM basis. Milk production and CH4 emissions were compared over two periods of two weeks during spring using eight lactating Holstein cows in a 2 × 2 Latin square design. Herbage organic matter intake (HOMI) was estimated by chromic oxide dilution and herbage organic matter digestibility (OMD) was estimated by faecal index. Methane emission was estimated by using the sulfur hexafluoride (SF6) tracer technique adapted to collect breath samples over 5-day periods. OMD (0.71) and HOMI (15.7 kg OM) were not affected by pasture composition. Milk production (20.3 kg/d), milk fat yield (742 g/d) and milk protein yield (667 g/d) were similar for both pastures. This may be explained by the high herbage allowance (30 kg DM above 5 cm/cow) which allowed the cows to graze selectively, in particular in grass sward. Similarly, methane emission expressed as absolute value (368 g/d or 516 L/d) or expressed as

ISS014-E-13598 (29 Jan. 2007) --- Montevideo, Uruguay is featured in this image photographed by an Expedition 14 crewmember on the International Space Station. Reflective roofing materials and dark asphalt streets outline the urban grid pattern of Uruguay's capital city of Montevideo in this image. The city may be viewed as a precursor of the predicted global population shift from dominantly rural to urban environments (by 2030, according to recent United Nations estimates) -- nearly half of Uruguay's total population now lives in the Montevideo metropolitan area. Located on the southern coastline of Uruguay along the Rio de la Plata, Montevideo Bay provides an important harbor and port facilities for transport of South American agricultural products. This view is of sufficient resolution (approximately 7 meters/pixel) to discriminate between dark green canopied tree cover and light green grass - important information for study of urban ecology and climate, as well as city water use planning - in a large golf course located at the southern edge of the city (near center right). Sediment plumes along the coastline to the southeast of the city are also visible; rough patterns in the water surface of Montevideo Bay and the Rio de la Plata are a combination of wind disturbance and sediments.

Radioastronomía: Una Mirada Más Amplia

The existence of the celestial bodies is known due to the light they emit. But light is a small part of a bigger phenomenon known as electromagnetic radiation. The representation of all kinds of electromagnetic radiation as a function of its frequency is called the electromagnetic spectrum. If we only studied the visible part of the spectrum, we would ignore a great deal of information. The celestial bodies emit radiation in all the regions of the electromagnetic spectrum, with very different intensity. To capture these data, astronomers design new types of telescopes that capture radiation at different wavelengths, among them the radiotelescopes that, as the name indicates, detect radio waves. The radiotelescope can be compared to a regular radio set. A radio station sends information by means of radio waves. The radio set captures these waves by means of its antenna, processes it and reproduces the information (music, etc.) in audible form. In the field of radioastronomy, interesting observations can be carried out: radio emission from stars, nebulas, pulsars, distant galaxies and stars, radiogalaxies, the Milky Way, the Sun, Jupiter, etc. La presencia de los cuerpos celestes se conoce gracias a que emiten luz. Pero la luz constituye solo una pequeña parte de un fenómeno mucho mas amplio conocido como radiación electromagnética. La representación de todas las clases de radiación como función de su frecuencia se denomina espectro electromagnético. Si solo estudiáramos la parte visual del espectro ignoraríamos una gran cantidad de información. Los cuerpos celestes emiten radiación en todas las regiones del espectro electromagnético, aunque con muy distinta intensidad. Para captar estos datos, los astrónomos deben diseñar nuevos tipos de telescopios que puedan captar la radiación de distintas longitudes de ondas, entre ellos los radiotelescopios, qué como su nombre lo indica detectan ondas de radio. El radiotelescopio puede compararse a un aparato

Staphylococcus aureus produces capsular polysaccharides (CPs) both in vivo and under defined culture conditions being serotypes 5 and 8 the most prevalent. S. aureus isolates that fail to produce CP5 or CP8 are defined as non-typeable (NT). Loss of capsule expression, however, may lead to S. aureus persistence in a chronically infected host. The prevalence of NT strains of S. aureus isolated from bovine mastitis varies according to the geographic origin of the strain. The aims of this work were to detect phenotypically and genotypically the capsular profile of 144 S. aureus isolated from bovine mastitis in Argentina, Chile, and Uruguay and explore the factors that are considered to be associated with capsule expression as presence of IS257, IScap, and agr typing of non-related collection. The detection of the IS257, IScap, cap genes, and agr typing was performed using PCR. The detection and quantification of capsular polysaccharide production were performed by ELISA assays. We found that 96% of the S. aureus isolates investigated carried cap5(8) genes but over 75% of strains do not express capsule in the three countries studied. However, only 6 isolates from Argentina carried the IScap element that totally suppressed the expression of the capsule, suggesting that other factors could influence on CP expression. Moreover, the agrI/NT association was statistically significant suggesting that this profile is a phenomenon observed not only in other parts of the world but also in our region.

El Río de la Plata (RdlP) presenta significativas variaciones naturales (hidrodinámicas y oceanográficas) asociadas a diferentes condiciones climáticas. El propósito de este trabajo es inferir los cambios de aportes continentales de sedimentos y su relación con las variaciones hidrológicas del Río de la Plata, a través del análisis de proxies sedimentológicos y geoquímicos en testigos de sedimentos de la plataforma interna uruguaya que registran los últimos 100 años, aproximadamente. A partir de la datación por 210Pb de dos testigos de sedimentos (GeoB 13813-4 y BAR1) se reconstruyó la geocronología del ambiente, y se relacionó con datos de las forzantes climáticas Pacific Decadal Oscillation, El Niño/La Niña Southern Oscillation, Atlantic Multidecadal Oscillation, y las anomalías hidrológicas de los ríos Paraná y Uruguay. Los valores más positivos y estables del Southern Oscillation Index, los cuales corresponden a fases La Niña, se observan en el periodo correspondiente entre 1910-1970, respecto al resto de la serie, donde se aprecia una mayor variabilidad y una tendencia hacia valores más negativos (eventos El Niño). Se hicieron dendrogramas (clustering) jerárquicos para ambos testigos. Para el testigo GeoB 13813-4, se utilizó la relación Ca/Ti y la granulometría, mientras que para BAR1 se recurrió a variables granulométricas y la tasa de sedimentación. El mayor aporte continental hacia la región de la plataforma adyacente al Río de la Plata registrado a partir del año 1970, podría ser el factor principal de los agrupamientos observados en los clusters para ambos testigos. Las agrupaciones mostraron una diferenciación en la década de 1970, lo que estaría asociado al aumento de los caudales de los ríos Paraná y Uruguay, durante las últimas tres décadas del siglo XX. Por otra parte se observa que la granulometría del testigo BAR1 presentó un mayor tamaño de grano y más variabilidad que en el caso del testigo Geo

In the last decade, Latin America has experienced important transformations in its health conditions, due to demographic changes and a rapid urbanization process. To analyze socioeconomic, demographic and epidemiological changes in Chile, Guatemala, Mexico and Uruguay and relate them to the different stages in the demographic and epidemiological transition of these countries. Data was obtained from official information of local and international organizations such as Pan-American Health Organization, United Nations, Latin American Center for Demography (CELADE) and World Bank. Guatemala is in a pre-transition stage with a high proportion of communicable diseases as causes of death (61%) as compared with Mexico (22%), Chile (13%) and Uruguay (7%). Mexico is in a prolonged transition situation and Chile is close to Uruguay in a post-transitional stage. Despite decreasing rates of mortality, the proportion of deaths represented by chronic diseases and injuries has increased to over 30% in all countries, except Uruguay. Adjusted mortality rates for cardiovascular diseases are lower in Latin American countries, as compared to Canada. However, excepting Guatemala, there are differences in the pattern of cardiovascular disease, with a higher mortality due to cerebrovascular and a lower mortality due to coronary artery diseases. An increment in non communicable diseases is expected for the next decades in Latin America. Analysis of demographic and epidemiological transition is crucial to define health policies and to adequate health systems to the new situations.

According to our experience, survival of cadaveric renal graft in 5 years increased from 63% as of the introduction of cyclosporine to 73% after azathioprine was substituted with mycophenolate mofetil (MMF) in 1997. Until 2003, the innovator mycophenolate mofetil (IMMF) (Cellcept; Roche) was used. In 2003, Laboratorios Clausen introduced in Uruguay a generic MMF (GMMF) (Suprimun/Micoflavin/Myclausen; Laboratorios Clausen) with previous bioequivalence studies. Since then, every health care provider administers one of these types of MMF available on the market to its renal transplant (RT) patients. We compared the evolution of 2 groups of patients and their grafts, those treated with GMMF or with IMMF. This was a descriptive, retrospective, nonrandomized, comparative study that involved all transplant patients in a center from January 2005 to June 2010 from 2 different health care providers which administered GMMF or IMMF uninterruptedly. Patients were older than 18 years, underwent their first RT and received triple immunosuppressive regime with calcineurin inhibitor (CNI), corticoids, and MMF, and completed ≥6 months of post-RT evolution. The GMMF group included 29 patients and the IMMF group 23. Patients from both groups had no significant differences (NS) regarding age, sex, diabetes, hepatitis C virus (HCV), recipient hypertension, donor type (living or cadaveric, sex, age, cause of death), or mismatch degree. There were no material differences regarding antibody induction, CNI type, day of diuresis, or function recovery percentage. Statistically different results were reported for time in dialysis (6.1 ± 0.7 y in IMMF vs 3.8 ± 0.5 y in GMMF) and cadaveric donor cold ischemia time (989 ± 205 min vs 851 ± 219 min, respectively). For IMMF and GMMF, respectively, clinical acute rejection was 40.9% and 31% and creatinine over 3, 6, 12, 24, 36, and 48 months, respectively, was (mg%): 1.65 ± 0.12, 1.66 ± 0.15, 1.43 ± 0.10, 1.44 ± 0.12, 1.49 ± 0.18, and 1

Paleoclimatic implications (Late Cretaceous-Paleogene) from micromorphology of calcretes, palustrine limestones and silcretes, southern Paraná Basin, Uruguay

2010-04-01

Sedimentologic and petrographic analyses of outcroping and subsurface calcretes, palustrine carbonates, and silcretes were carried out in the southern Paraná Basin (Uruguay). The aim of this work is to describe the microfabric and interpret the genesis of these rocks through detailed analyses, since they contain significant paleoenvironmental and paleoclimatic evolution information. The main calcrete and silcrete host rock (Mercedes Formation) is represented by a fluvial thinning upward succession of conglomerate and sandstone deposits, with isolated pelitic intervals and paleosoils. Most of the studied calcretes are macroscopically massive with micromorphological features of alpha fabric, originated by displacive growth of calcite in the host clastic material due to evaporation, evapotranspiration and degassing. Micromorphologically, calcretes indicate an origin in the vadose and phreatic diagenetic environments. Micrite is the principal component, and speaks of rapid precipitation in the vadose zone from supersaturated solutions. The abundance of microsparite and secondary sparite is regarded as the result of dissolution and reprecipitation processes. Although present, brecciated calcretes are less common. They are frequent in vadose diagenetic environments, where the alternation between cementation and non-tectonic fracturing conditions take place. These processes generated episodes of fragmentation, brecciation and cementation. Fissures are filled with clear primary sparitic calcite, formed by precipitation of extremely supersaturated solutions in a phreatic diagenetic environment. The micromorphological characteristics indicate that calcretes resulted from carbonate precipitation in the upper part of the groundwater table and the vadose zone, continuously nourished by lateral migration of groundwater. The scarcity of biogenic structures suggests that they were either formed in zones of little biological activity or that the overimposed processes related to

The objectives of this study are to compare the prevalence of MIH in children seeking dental care spontaneously at the Department of Comprehensive Children's Dentistry of the University of Buenos Aires (UBA) and Department of Pediatric Dentistry of the University of La República (UdelaR) and to analyze the distribution according to year of birth, sex, age, number of affected teeth and maximum degree of severity in molars and incisors. During 2010, nine pediatric dentists from both schools (Kappa = 0.94) assessed all children born between 1993 and 2003 whose 4 first molars and 8 permanent incisors had erupted. Specially designed charts were used to record sex, year of birth, institution, presence of MIH, number of affected incisors and molars and maximum degree of severity for each tooth. Two groups were formed: UBA: A (n = 512) and UdelaR: B (n = 463). 975 children (11.6 +/- 2.67 years) were evaluated. The prevalence of MIH in the total sample was 6.56%, without significant differences between A and B (p = 0.76). There was no significant difference between groups regarding age (p = 0. 95) or sex (p = 0.30). A significant increase was found in both institutions according to year of birth during the study period. (A: p = 0.0017) B: p = 0. 0058). The results of this study show a similar prevalence of MIH among patients seeking dental care at the Schools of Dentistry of the University of Buenos Aires (Argentina) and University of la República (Uruguay). No significant difference was found comparing the distribution by sex, affected teeth or severity of each tooth. A highly significant positive correlation was found regarding the year of birth. The relevance of MIH as an emerging pathology requires studies on larger samples covering the entire countries.

The absorption, distribution, metabolism and excretion (ADME) of metabolites and toxic organic solutes are orchestrated by the ATP-binding cassette (ABC) transporters and the organic solute carrier family (SLC) proteins. A large number of ABC and SLC transpoters exist; however, only a small number have been well characterized. To facilitate the analysis of these transporters, which is important for drug safety and physiological studies, we developed a sensitive genetically encoded bilirubin (BR)-inducible fluorescence sensor (eUnaG) to detect transporter-coupled influx/efflux of organic compounds. This sensor can be used in live cells to measure transporter activity, as excretion of BR depends on ABC and SLC transporters. Applying eUnaG in functional RNAi screens, we characterize l(2)03659 as a Drosophila multidrug resistant-associated ABC transporter. PMID:28176814

Introducción: El síndrome de outlet torácico es una compresión del plexo braquial que suscita polémica. Se clasifica en Outlet Torácico Verdadero o neurogénico (OTV) y Outlet Torácico Disputado o no neurogénico (OTD). El primero presenta síntomas motores en la mano, mientras que el segundo sólo síntomas sensitivos en el miembro superior. El objetivo de este trabajo es analizar los resultados obtenidos en una serie de 31 cirugías. Métodos: Se analizaron las cirugías de nervios efectuadas entre 2003-2012, tomando los diagnósticos de outlet torácico cuyo período de seguimiento post-operatorio mínimo fuera de 6 meses. Se buscaron los siguientes datos: edad, sexo, presencia de síntomas sensitivos y/o motores, clasificación, resultado de los estudios neurofisiológicos y de imágenes, resultado de la cirugía, complicaciones post-operatorias y recidivas. Resultados: Se incluyeron 31 cirugías realizadas en 30 pacientes, 9 OTV (8 mujeres) de 24.3 años, y 21 con OTD (18 mujeres) de 37.4 años de edad en promedio. Un 90% presentaron alteraciones neurofisiológicas preoperatorias, y 66,6% imagenológicas. En el intraoperatorio, el 100% de los OTV presentó una alteración anatómica relacionada con la sintomatología, hecho observado sólo en el 36.7% de los OTD operados. El 87,5% de los OTV mejoraron sensitivamente, mientras que 77,7% mejoraron la atrofia. Por el contrario, 45.4% de los OTD mejoraron permanentemente, 36.3% no tuvieron cambios, 13.6% mejoraron transitoriamente y 4.5% (un caso) empeoró. Las complicaciones post-operatorias fueron más frecuentes aunque transitorias en el grupo de OTV (3 casos sobre 9 operados, 33.3%) que en los OTD (3 casos sobre 22, un 13.6%). Conclusión: El OTV suele mayormente mejorar luego de la cirugía, igual que el OTD aunque en una proporción mucho menor. Estos hallazgos coinciden con otros reportes recientes de esta patología.

Introducción: los meningiomas del foramen óptico producen un rápido deterioro de la función visual aún cuando su tamaño es pequeño, por eso su diagnóstico y manejo difiere del resto de los meningiomas clinoideos. El propósito de este estudio es presentar la técnica y los resultados de nuestro manejo quirúrgico de meningiomas foraminales (MF). Pacientes y Métodos: se llevó a cabo una revisión de las historias clínicas de 47 pacientes con meningiomas primarios intraorbitarios. Se realizaron 52 cirugías en los pacientes con MF. Se empleó una craneotomía fronto-orbitaria, seguida de una descompresión extradural del canal óptico, resección del componente intraorbitario y exploración intradural del nervio óptico. Resultados: de los 12 pacientes con MF que presentaban la visión conservada, la agudeza visual fue preservada en 7 casos, mejoró en 2, y empeoró en 3. En 18 pacientes, el principal síntoma fue exoftalmos y en 35 pacientes ceguera unilateral. Ocurrieron 6 recurrencias, 2 a 10 años después de la resección quirúrgica. Cinco de ellos fueron reoperados. Se indicó radioterapia después de la recurrencia en 3 pacientes. Conclusión: el manejo de los MF continúa siendo controvertido y frecuentemente se propone un tratamiento conservador. Basados en nuestros hallazgos de frecuente extensión intracraneal, proponemos realizar una resección total o subtotal del tumor, preservando el nervio óptico en pacientes con visión prequirúrgica conservada.

There are not enough data concerning asthma mortality in Latin America. The Latin American Society of Allergy and Immunology coordinated this project to provide reliable data for gaining knowledge about our present situation, which is a condition indispensable to changing it. The following countries participated in this study: Argentina, Brazil, Chile, Colombia, Costa Rica, Cuba, Mexico, Paraguay, Peru, Uruguay and Venezuela. A uniform protocol was designed in Santa Fe, Argentina. Asthma mortality rates were analyzed in accordance with two variables: age-adjusted rates (5-34) and total death rates. The total population studied was 107, 122, 529 inhabitants. The highest death rates were found in Uruguay and Mexico (5.63), and the lowest in Paraguay (0.8) and Colombia (1.35). Age-adjusted (5-34) rates were higher in Costa Rica (1.38) and lower in Chile (0.28). Regarding sex, the analysis of the information provided by seven countries showed a predominance of females (51.8%) over males (48.18%). In the southern Latin American countries such as Chile, Uruguay, Paraguay and Argentina, which have marked climatic differences, deaths occurred mainly in the winter. It is important to emphasize that, in most countries, deaths from asthma occurred at home: Chile (60.7%), Argentina (63.4%) and Paraguay (88%). However, in Uruguay, 58.6% occurred during hospitalization. Mortality rates from bronchial asthma are high in most of the Latin American countries studied, even though further studies are needed. Asthma is a serious global health problem. People of all ages in countries throughout the world are affected by this chronic airway disorder that can be severe and sometimes fatal. The health ministries of each country do not believe asthma is a significant issue. Therefore, we should provide them with sound epidemiological studies to convince them to change their attitude toward this disease.

Identification of Suitable Water Harvesting Zones Based on Geomorphic Resources for Drought Areas: A Case Study of Una District, Himachal Pradesh, India.

NASA Astrophysics Data System (ADS)

Prakasam, D. C., Jr.; Zaman, B.

2014-12-01

Water is one of the most vital natural resource and its availability and quality determine ecosystem productivity, both for agricultural and natural systems. Una district is one of the major potential agricultural districts in Himachal Pradesh, India. More than 70% of the population of this district is engaged in agriculture and allied sectors and major crops grown are maize, wheat, rice, sugarcane, pulses and vegetables. The region faces drought every year and about 90 per cent of the area is water stressed. This has resulted in crop loss and shortage of food and fodder. The sources of drinking water, small ponds and bowlies dry-up during summer season resulting in scarcity of drinking water. Una district receives rainfall during monsoons from June to September and also during non-monsoon period (winter). The annual average rainfall in the area is about 1040 mm with 55 average rainy days. But due to heavy surface run-off the farmers not able to cultivate the crops more than once in a year. Past research indicate that the geomorphology of the Una district might be responsible for such droughts as it controls the surface as well as ground water resources. The research proposes to develop a water stress model for Una district using the geomorphic parameters, water resource and land use land cover data of the study area. Using Survey of India topographical maps (1:50000), the geomorphic parameters are extracted. The spatial layers of these parameters i.e. drainage density, slope, relative relief, ruggedness index, surface water body's frequency are created in GIS. A time series of normalized remotely sensed data of the study area is used for land use land cover classification and analyses. Based on the results from the water stress model, the drought/water stress areas and water harvesting zones are identified and documented. The results of this research will help the general population in resolving the drinking water problem to a certain extent and also the

Borteiro, Claudio; Cruz, Juan Carlos; Kolenc, Francisco; Aramburu, Andrea

2009-04-06

Amphibian chytridiomycosis caused by Batrachochytrium dendrobatidis is reported in Uruguayan native amphibians for the first time. Histological evidence of infection was observed in tadpoles of Hypsiboas pulchellus, Odontophrynus maisuma, Physalaemus henselii, and Scinax squalirostris. The effects of chytridiomycosis on these species are still unknown. However, the disease is of potential concern for the conservation of the apparently declining species P. henselii and also for O. maisuma, given its restricted distribution in habitats which are being increasingly disturbed.

This work is the result of the analysis of existing information in the earthquake database of the Observatorio Sismológico y Vulcanológico de Costa Rica, Universidad Nacional (OVSICORI-UNA), and seeks disclosure of basic seismological information recorded and processed in 2010. In this year there was a transition between the software used to record, store and locate earthquakes. During the first three months of 2010, we used Earthworm (http://folkworm.ceri.memphis.edu/ew-doc), SEISAN (Haskov y Ottemoller, 1999) and Hypocenter (Lienert y Haskov, 1995) to capture, store and locate the earthquakes, respectively; in April 2010, ANTELOPE (http://www.brtt.com/software.html) start to be used for recording and storing and GENLOC (Fan at al, 2006) and LOCSAT (Bratt and Bache 1988), to locate earthquakes. GENLOC was used for local events and LOCSAT for regional and distant earthquakes. The local earthquakes were located using the 1D velocity model of Quintero and Kissling (2001) and for regional and distant earthquakes IASPEI91 (Kennett and Engdahl, 1991) was used. All the events for 2010 and shown in this work were rechecked by the authors. We located 3903 earthquakes in and around Costa Rica and 746 regional and distant seismic events were recorded (see Figure 1). In this work we also give a summary of major earthquakes recorded and located by OVSICORI-UNA network between 1983 and 2012. Seismicity recorded by OVSICORI-UNA network in 2010

Ortiz Benavides, Fedra Lorena

El proposito de la investigacion fue evaluar la efectividad de una actividad de aprendizaje basado en la argumentacion dialogica en linea y su incidencia en el desarrollo de competencias cientificas. Se fundamenta en la teoria del aprendizaje socio cultural de Vigotsky (1984), los principios del diseno instruccional de la cognicion situada por Hung y Der-Thang (2001) y como estrategia se aplico la argumentacion dialogica utilizando el Modelo Argumentativo de Toulmin MAT (1984). El diseno experimental comparo dos grupos de estudiantes A y B en el curso virtual de Biotecnologia. El grupo A (experimental) desarrollo la discusion a partir de la estrategia disenada para este estudio y el grupo B (control) realizo la discusion desde las actividades tradicionales. El desarrollo de la competencia argumentativa se valoro con el instrumento de evaluacion para argumentacion dialogica en linea propuesta por Clark y Sampson (2008). La evaluacion de las competencias cientificas se realizo a partir de una postprueba. Los datos fueron analizados con pruebas estadisticas no parametricas. Los resultados de la investigacion, indicaron diferencias significativas en el nivel de la competencia argumental en el grupo experimental en comparacion al grupo control. Igualmente se demostro que existe una relacion positiva entre el nivel de desarrollo de la competencia argumentativa y el nivel de desarrollo de las competencias cientificas.

To report total fluid intake (TFI) and the intake of different fluid types in adults (≥ 18 years old) from Mexico, Argentina, Brazil and Uruguay. To compare intakes between countries and with recommended adequate intake (AI) of water from fluids. Cross-sectional data were collected using a validated liquid intake 7-day record (Liq.In 7 ) in populations from Argentina (n = 1089), Brazil (n = 477), Mexico (n = 1677) and Uruguay (n = 554). Population characteristics, including age, gender, body mass index and socioeconomic level were recorded. Mean TFI was compared with the AI of water from fluids set by the USA Institute of Medicine. The lowest TFI was recorded in Mexican women (1748 mL/day) and the highest in Argentinean men (2318 mL/day). Median daily TFI was significantly different between countries; Uruguay and Argentina had higher values than Mexico and Brazil. In the former, plain water contributed to only 25% of TFI, the remainder being predominantly from hot beverages. Approximately, a third of adults did not drink enough fluid to meet the recommended AI. High SSB consumption was reported, which was significantly different between countries (p < 0.05), the highest being in Mexico (median 25-75th percentiles): 531 (300-895 mL/day. This survey highlights the need to increase water consumption and reduce SSB intake in this region to avoid potential associated health risks. These findings may be useful information in monitoring public health policy strategies.

To assess drinking occasions (volume and type) according to consumption with food in or outside meals, and location, for six countries. A total of 10,521 participants aged 4-65 years from Argentina, Brazil, China, Indonesia, Mexico and Uruguay completed a validated 7-day fluid intake record. For each drinking event, the volume consumed, the fluid type, the location of intake, and whether the drink was accompanied by food (meal or snack) or not, was recorded. Similar drinking behaviors were found in Mexico and Argentina; fluid intake during meals was 48 and 45% of total fluid intake (TFI), respectively. In Brazil (55%), Indonesia (58%) and China (66%) most fluid was consumed without food. In Uruguay, 34% of TFI was with a main meal, 31% with food between meals and 35% without food. Indonesia had the highest median (25-75th percentile) TFI; 2520 (1750-3347) mL/day, and China the lowest 1138 (818-3347) mL/day. Water was consumed with meals for 37% of Chinese and 87% of Indonesian participants, while the four Latin-American American countries showed a preference for sweet drinks; 54% in Mexico, 67% in Brazil, 55% in Argentina and 59% in Uruguay. Diversity in fluid type was noted when drinking with food between meals. Apart from China, most drinking occasions (> 75%) occurred at home. Three distinct drinking behaviors were identified, namely, drinking with meals, drinking as a stand-alone activity, and a type of 'grazing' (i.e., frequent drinks throughout the day) behavior. Most drinking occasions occurred at home.

Evidence of bias of self-reported smoking cessation during pregnancy is reported in high-income countries but not elsewhere. We sought to evaluate self-reported smoking cessation during pregnancy using biochemical verification and to compare characteristics of women with and without biochemically confirmed cessation in Argentina and Uruguay. In a cross-sectional study from October 2011 to May 2012, women who attended one of 21 prenatal clinics and delivered at selected hospitals in Buenos Aires, Argentina and Montevideo, Uruguay, were surveyed about their smoking cessation during pregnancy. We tested saliva collected from women <12 h after delivery for cotinine to evaluate self-reported smoking cessation during pregnancy. Overall, 10.0% (44/441) of women who self-reported smoking cessation during pregnancy had biochemical evidence of continued smoking. Women who reported quitting later in pregnancy had a higher percentage of nondisclosure (17.2%) than women who reported quitting when learning of their pregnancy (6.4%). © 2014 Nordic Federation of Societies of Obstetrics and Gynecology.

The Pampas is a Neotropical biome formed primarily by low altitude grasslands and encompasses the southernmost portion of Brazil, Uruguay, and part of Argentina. Despite the high level of endemism, and its significant environmental heterogeneity, Pampean species are underrepresented in phylogeographic studies, especially aquatic organisms. The Pampean hydrological system resulted from a long history of tectonism, climate, and sea level changes since the Neogene. In this study, we examined the population genetic structure of Cnesterodon decemmaculatus, a freshwater fish species that occurs throughout most of the Pampa biome. We characterized mitochondrial and autosomal genetic lineages in populations sampled from Southern Brazil and Uruguay to investigate (1) the correspondence between current drainage systems and evolutionary lineages, (2) the demographic history for each genetic lineage, and (3) the temporal depth of these lineages. Overall, we found that the major evolutionary lineages in this species are strongly related to the main Pampean drainage systems, even though stream capture events may have affected the distribution of genetic lineages among drainages. There was evidence for recent population growth in the lineages occupying drainages closest to the shore, which may indicate the effect of quaternary sea-level changes. In general, divergence time estimates among evolutionary lineages were shallow, ranging from 20,000 to 800,000 years before present, indicating a geologically recent history for this group, as previously reported in other Pampean species. A Bayesian phylogeographical reconstruction suggested that an ancestral lineage probably colonized the Uruguay River Basin, and then expanded throughout the Pampas. This evolutionary scenario may represent useful starting models for other freshwater species having a similar distribution. PMID:29312439

There is little information about familial hypercholesterolemia (FH) epidemiology and care in Ibero-American countries. The Ibero-American FH network aims at reducing the gap on diagnosis and treatment of this disease in the region. To describe clinical, molecular, and organizational characteristics of FH diagnosis in Argentina, Brazil, Chile, Colombia, Mexico, Portugal, Spain, and Uruguay. Descriptive analysis of country data related to FH cascade screening, molecular diagnosis, clinical practice guidelines, and patient organization presence in Ibero-America. From a conservative estimation of an FH prevalence of 1 of 500 individuals, there should be 1.2 million heterozygous FH individuals in Ibero-America and roughly 27,400 were diagnosed so far. Only Spain, Brazil, Portugal, and Uruguay have active cascade screening programs. The prevalence of cardiovascular disease ranged from 10% to 42% in member countries, and the highest molecular identification rates are seen in Spain, 8.3%, followed by Portugal, 3.8%, and Uruguay with 2.5%. In the 3 countries with more FH patients identified (Spain, Portugal, and Brazil) between 10 and 15 mutations are responsible for 30% to 47% of all FH cases. Spain and Portugal share 5 of the 10 most common mutations (4 in low density lipoprotein receptor [LDLR] and the APOB3527). Spain and Spanish-speaking Latin American countries share 6 of the most common LDLR mutations and the APOB3527. LDL apheresis is available only in Spain and Portugal and not all countries have specific FH diagnostic and treatment guidelines as well as patient organizations. Ibero-American countries share similar mutations and gaps in FH care. Copyright © 2016 National Lipid Association. Published by Elsevier Inc. All rights reserved.

Resumen Introducción: Los meningiomas Grado II tienen un comportamiento biológico más agresivo que los Grado I. A partir del año 2007, con los nuevos criterios de clasificación, la incidencia de meningiomas atípicos reportada aumentó hasta un 35%. Objetivo: Establecer diferencias entre los Meningiomas Grado I y II de la clasificación de la OMS, en lo que respecta a: grados de resección de Simpson, localización tumoral, necesidad de reintervención, tratamiento adyuvante, evolución y mortalidad. Métodos: Estudio retrospectivo de 63 pacientes operados entre el periodo 2009-2015. Variables analizadas: sexo, edad, grado histológico, localización, grado de resección quirúrgica, radioterapia adyuvante, mortalidad y evolución. Resultados: Se analizaron 63 pacientes: 51 Grado I y 12 Grado II de la clasificación de la OMS. La distribución por sexo no mostró diferencias entre meningiomas benignos y atípicos. Tampoco el grupo etario de presentación; mediana de 57 años. Un 55% de los meningiomas benignos se localizaron fuera de la base del cráneo versus el 91,6% de los meningiomas atípicos (P = 0.02). En el 74,5% de los meningiomas benignos se logró una resección total (Simpson I-II-III) versus el 58.3% para los atípicos (P = 0.3). Se reintervinieron el 33,3% de meningiomas atípicos en comparación con el 9.8% de los benignos (P = 0.03). Tuvieron una buena evolución el 86,2% de los benignos vs el 53,8% de los GII (P = 0.01). Realizaron radioterapia adyuvante el 33,3% de los meningiomas Grado II vs el 1,9% de los Grado I. Conclusiones: Los meningiomas atípicos cerebrales tienen peor pronóstico evolutivo que los Grado I de la OMS. Presentan una mayor tasa de reintervención y se localizan más frecuentemente fuera de la base del cráneo. La localización pareciera ser un factor de riesgo para el desarrollo de meningiomas atípicos.

Introducción. La etapa posprandial se asocia con el incremento de marcadores relacionados con el riesgo cardiovascular, cuya intensidad depende del estado metabólico.Objetivo. Determinar el impacto de la ingestión de una comida rica en grasas saturadas sobre el perfil metabólico e inflamatorio y su relación con la obesidad abdominal.Materiales y métodos. Se hizo un ensayo clínico en 42 individuos (21 con obesidad abdominal). Se midieron, en sangre, la glucosa, la insulina, el perfil lipídico, la proteína C reactiva, los lipopolisacáridos y la interleucina 6, en ayunas y después de la ingestión.Resultados. Además de la obesidad, se registró la presencia de resistencia a la insulina y de niveles elevados de triacilglicéridos y proteína C reactiva en ayunas. Asimismo, se detectaron niveles posprandiales más elevados de glucosa, insulina y triacilglicéridos. La interleucina 6 disminuyó en el grupo de personas sin obesidad y los lipopolisacáridos aumentaron en ambos grupos.Conclusión. La ingestión de una comida rica en grasas saturadas produjo un mayor impacto en las variables glucémicas en el grupo con obesidad y, aunque afectó de forma similar los lípidos en ambos grupos, el incremento de triacilglicéridos fue mayor en presencia de una concentración basal elevada y promovió el aumento de lipopolisacáridos. El estado inflamatorio basal y posprandial afectó en mayor medida al grupo con obesidad. El momento posprandial reflejó el estado más frecuente de los individuos en un día normal y permitió evidenciar la capacidad de respuesta metabólica frente a la ingestión de alimentos, así como los estados tempranos de riesgo metabólico.

This qualitative research study investigated intrapersonal, interpersonal, and environmental factors that shape young adolescent tobacco use behaviors in Uruguay. Focus groups were conducted in the summer of 2012 and fall of 2013 in four secondary schools in Montevideo, Uruguay, including two private schools and two public schools. A total of four focus groups were led in each school, composed of 4-6 students each, 16 focus groups in total. Data analysis utilized NVivo software and included deductive and inductive content analysis. Overwhelmingly, students reported that the onset of smoking occurred in the second year of secondary school. The primary intrapersonal factors that were found to be universal among respondents identified that smoking was a performance in groups, to garner attention from their peers. Students interviewed most often stated that the greatest interpersonal factors for smoking were to look older, as a rite of passage, and for group membership. Environmental factors cited most often indicate that they smoked during unsupervised time, either at night or around the short Uruguayan school day. Focus group interviews revealed that adolescents had easy access to cigarettes for purchase through small family owned grocery stores, even though laws exist preventing the sale of cigarettes to minors. Few differences were cited between strata related to cigarette use in adolescents. The differences that do exist are most apparent across gender, though there were a few observed differences when stratified by public and private school. Findings from this study indicate that key factors across ecological levels (intrapersonal, interpersonal, and environmental) should be taken into consideration when designing tobacco prevention programs for youth in Uruguay. A multiple-component approach which addresses risk factors at all of these levels, implemented in schools, may be particularly well-suited to this setting.

In Uruguay, as in many developed and developing countries, rotavirus and norovirus are major causes of diarrhea and others symptoms of acute gastroenteritis. In some areas of Uruguay, groundwater is the only source of water for human consumption. In the rural area of the Salto district, virus contamination has been detected in several groundwater wells. Because sewer coverage is low, the most probable sources of contamination are nearby septic systems. This work aims to evaluate the transport of rotavirus and norovirus from clinic samples in two sets of column experiments under saturated conditions: 6.7-cm columns with quartz sand (ionic strength 1mM, pH 7.0) and with sand from the Salto aquifer (Uruguay) (9,2% coarse sand, 47,8% medium sand, 40,5% fine sand, magnesium/calcium bicarbonate water, Ionic strength 15.1 mM, pH 7.2). Both viruses were seeded for 2 pore volumes onto the columns. Samples were collected at the column outlet and viruses were enumerated by Q-PRCR. Breakthrough curves were constructed and fitted to a two-site kinetic attachment/detachment model, including blocking using Hydrus-1D. In the quartz sand column, both rotavirus and norovirus were removed two orders in magnitude. In the Salto sand column, rotavirus was removed 2 log10 as well, but norovirus was removed 4 log10. The fitting of the breakthrough curves indicated that blocking played a role for rotavirus in the Salto sand column. These results are consistent with the field observation where only rotavirus was detected in the Salto aquifer, while similar concentrations in Salto sewer effluent were measured for both viruses. This work, besides reporting actual parameters values for human virus transport modelling, shows the significant differences in transport that human viruses can have in standardised and natural soil-water systems.

Bovine tuberculosis (bTB) poses serious risks to animal welfare and economy, as well as to public health as a zoonosis. Its etiological agent, Mycobacterium bovis, belongs to the Mycobacterium tuberculosis complex (MTBC), a group of genetically monomorphic organisms featured by a remarkably high overall nucleotide identity (99.9%). Indeed, this characteristic is of major concern for correct typing and determination of strain-specific traits based on sequence diversity. Due to its historical economic dependence on cattle production, Uruguay is deeply affected by the prevailing incidence of Mycobacterium bovis. With the world's highest number of cattle per human, and its intensive cattle production, Uruguay represents a particularly suited setting to evaluate genomic variability among isolates, and the diversity traits associated to this pathogen. We compared 186 genomes from MTBC strains isolated worldwide, and found a highly structured population in M. bovis. The analysis of 23 new M. bovis genomes, belonging to strains isolated in Uruguay evidenced three groups present in the country. Despite presenting an expected highly conserved genomic structure and sequence, these strains segregate into a clustered manner within the worldwide phylogeny. Analysis of the non-pe/ppe differential areas against a reference genome defined four main sources of variability, namely: regions of difference (RD), variable genes, duplications and novel genes. RDs and variant analysis segregated the strains into clusters that are concordant with their spoligotype identities. Due to its high homoplasy rate, spoligotyping failed to reflect the true genomic diversity among worldwide representative strains, however, it remains a good indicator for closely related populations. This study introduces a comprehensive population structure analysis of worldwide M. bovis isolates. The incorporation and analysis of 23 novel Uruguayan M. bovis genomes, sheds light onto the genomic diversity of this

We present historic and contemporary information on the distribution and abundance of Buff-breasted Sandpipers (Tryngites subruficollis) in South America. Historic information was collated from the literature, area ornithologists, and museums, whereas contemporary data were derived from surveys conducted throughout the main wintering range in Argentina, Uruguay, and Brazil during the austral summers of 1999 and 2001. Variable circular plot sampling was used to estimate population densities. During 1999, the highest concentration of Buff-breasted Sandpipers in Argentina was in southern Bahía Samborombón (General Lavalle District) and areas north of Mar Chiquita coastal lagoon. During 2001, the highest concentrations in Brazil were at Ilha da Torotama and Lagoa do Peixe National Park. During 1999 and 2001, the highest concentrations of Buff-breasted Sandpipers in Uruguay were found along three lagoons (Laguna de Rocha, Laguna de Castillos, and Laguna Garzón) bordering the Atlantic Ocean. Population densities (birds/ha) of Buff-breasted Sandpipers were 0.11 (95% C.I. = 0.04–0.31) in Argentina, 1.62 (0.67–3.93) in Brazil, and 1.08 (0.37–3.18) in Uruguay. High turnover rates at survey sites, due to the formation of large, mobile flocks, contributed to moderately large confidence intervals around our population density estimates. Nevertheless, compared with historic accounts of Buff-breasted Sandpipers, our survey data indicate the population size of this species has declined substantially since the late 1800s and contemporary information suggests the species has continued to decline during the past three decades. Buff-breasted Sandpipers were found almost exclusively in pasturelands and appear to depend heavily upon intensive grazing by livestock, which maintain suitable short grass conditions. We discuss the need for protection of critical areas and proper range management to ensure appropriate habitat remains available for the species, and provide suggestions

Attitudes Toward Partner Violence and Gender Roles in Uruguayan Women.

PubMed

Bucheli, Marisa; Rossi, Maximo

2015-09-07

The incidence of intimate partner violence (IPV) in the Latin America and Caribbean region is relatively high compared with other high-income and middle-income countries. This problem is particularly relevant in Uruguay. The empirical literature provides evidence that violence toward partners is more likely among individuals who justify, approve, or favor this type of violence. This article analyzes women's attitudes to IPV using the survey Encuesta de Situaciones Familiares carried out in 2007 by Universidad de la República, Innovation National Agency in Uruguay (ANII), and the United Nations Children's Fund (UNICEF). The data show that most women disagree with IPV; the indifference and justification of IPV have a very low prevalence. The analysis highlights that women's attitudes to IPV against men and against women are highly correlated and are explained by the same factors. A multivariate estimation indicates that the experience of violence in childhood, the strong identification of the woman as a mother, and the low confidence on women's abilities in political and business activities increase tolerance toward IPV. © The Author(s) 2015.

Chimarrão or mate is a popular beverage from South America that is drank with successive infusions. Although yerba mate extracts have been widely studied, few studies have described the extract contents in beverages. Using yerba mate samples from Brazil, Argentina, and Uruguay, we examined the extract chromatographic profiles, total polyphenol content and their capacities to chelate iron. In addition, we analyzed antioxidant activity by examining the ability of the extracts to scavenge DPPH and NO. Our results showed that the amount of extracted compound was highest in yerba mate extract from Uruguay, followed by Argentina, then Brazil. Herbs from all three areas had a significant capacity to inhibit DPPH and NO free radicals. The Brazilian and Uruguayan herbs had an 80% iron chelation capacity (p<0.001), while the iron chelation capacity of the Argentinean herb was lower but still significant (p⩽0.05). We conclude that the compound concentration decreases with successive extractions, while the antioxidant capacity is maintained at significant levels. Copyright © 2016 Elsevier Ltd.

Ramos, R. Soledad; Brea, Mariana; Kröhling, Daniela M.

2017-11-01

The main aim of the present paper is to describe the first Detarioideae fossil woods from El Palmar Formation (Late Pleistocene) in the Uruguay River Basin (Entre Ríos, Argentina). This study is based on five silicified wood specimens preserved in fluvial deposits, which were transported from their growth site. Two new genera and species are described: Paraoxystigma concordiensis gen. nov and sp. nov. has medium-sized vessels, paratracheal axial parenchyma, heterocellular and multiseriate rays, and diffuse axial canals similar in size and shape to vessels, and Gossweilerodendroxylon palmariensis gen. nov and sp. nov. has medium-sized vessels, alternate intervessel pits, paratracheal and apotracheal axial parenchyma, homocellular and uni to-multiseriate rays, and small diffuse axial canals. These Detarioideae fossil records in south-eastern South America support the existence of a very old relationship with the extant West African forests. Eco-anatomical features observed in these fossil woods, along with the climatic information available from the Nearest Living Relatives (NLRs) comparison, suggest warm and humid climatic conditions for the upper-middle basin of the Uruguay River during some periods of the Late Pleistocene.

The effect of country of origin (local, Switzerland, Argentina, Uruguay), finishing diet (grass, grass plus concentrate, concentrate), and price (low, medium, high) on consumer's beef choice and segmentation was evaluated in Spain, France and United Kingdom. Sensory acceptability of Uruguayan beef from different production systems was also evaluated and contrasted with consumers' beef choices. Origin was the most important characteristic for the choice of beef with preference for meat produced locally. The second most important factor was animal feed followed by price with preference for beef from grass-fed animals and lowest price. The least preferred product was beef from Uruguay, concentrate-fed animals and highest price. Sensory data showed higher acceptability scores for Uruguayan beef from grass-fed animals with or without concentrate supplementation than animals fed concentrate only. Consumer segments with distinct preferences were identified. Foreign country promotion seems to be fundamental for marketing beef in Europe, as well as the development of different marketing strategies to satisfy each consumer segment.

2017-04-01

The objective of this study was to assess the effect of the probiotic Lactobacillus murinus native strain (LbP2) on general clinical parameters of dogs with distemper-associated diarrhea. Two groups of dogs over 60 d of age with distemper and diarrhea were used in the study, which was done at the Animal Hospital of the Veterinary Faculty of the University of Uruguay, Montevideo, Uruguay. The dogs were treated orally each day for 5 d with the probiotic or with a placebo (vehicle without bacteria). Clinical parameters were assessed and scored according to a system specially designed for this study. Blood parameters were also measured. Administration of the probiotic significantly improved the clinical score of the patients, whereas administration of the placebo did not. Stool output, fecal consistency, mental status, and appetite all improved in the probiotic-treated dogs. These results support previous findings of beneficial effects with the probiotic L. murinus LbP2 in dogs. Thus, combined with other therapeutic measures, probiotic treatment appears to be promising for the management of canine distemper-associated diarrhea.

Benvenuto, O. G.; Althaus, L. G.; Torres, D. F.

En este trabajo se estudia por primera vez de manera autoconsistente la evolución de las estrellas enanas blancas en el caso de una constante de gravitación G variable en el tiempo. Teniendo en cuenta que: 1) las enanas blancas son en general estrellas muy viejas y 2) su fuente de energía es básicamente de origen térmico y gravitacional, estos objetos son en principio muy adecuados para analizar distintas teorías de gravitación. Los cálculos que aquí presentamos fueron realizados utilizando nuestro código de evolución estelar, el cual calcula la evolución de estrellas enanas blancas por medio del esquema iterativo de Henyey. Dicho código, basado en una descripción física muy detallada, ha sido modificado para tener en cuenta la variación del valor de G. Encontramos que un G variable (decreciente en el tiempo) modifica fuertemente la evolución de las enanas blancas, conduciendo a un rápido enfriamiento de la estrella. Nuestros resultados son comparados con recientes datos observacionales sobre la función de luminosidad de las enanas blancas.

Coordination of NEO Observers in South-America

NASA Astrophysics Data System (ADS)

Tancredi, G.

At present the discovery of NEOs is concentrated in the Northern Hemisphere. None of the 6 existing survey programs can reach declinations below -30deg. Nevertheless, there are two small surveys ready to start in the near future in the southern hemisphere: an extension of the Catalina Sky Survey using the Uppsala Schmidt in Siding Spring and the Project BUSCA in Uruguay. Many of the NEOs discovered by the northern surveys could reach the southern sky, with declinations unreachable for a northern observer. Furthermore, the recovery of an asteroid in subsequent oppositions could come indistinctly in the northern and southern sky. A network of well-equipped observers in the southern region is then a must in a campaign to catalog the NEO population. In view of this situation, the Planetary Society, through its NEO grant, have already supported many observers in the Southern Hemisphere. The planetary science community in South America has considerably grown in the last 10 years. We have well-known research groups in Argentina, Brazil and Uruguay. Those groups have established many scientific links by exchanging graduate students and through several meetings. In particular, we have already hold two Workshop in Planetary Science in South America in 1999 (La Plata, Argentina) and 2000 (Montevideo, Uruguay) with more than 25 participants each. Recently, in February 2002, we organized a Workshop of NEO observers in Montevideo with the participation of more than 20 professional and amateurs observers from: Argentina: Obs. Ast. Felix Aguilar - Yale University (San Juan) and CRICYT (Mendoza); Brazil: Obs. Abraes de Moraes (San Pablo), Obs. Wykrota (Belo Horizonte) and Observatorio Nacional (Rio de Janeiro); Paraguay: Obs.

To describe strategies that contribute to the comprehensive approach to the judicialization of health in countries of Latin America and the Caribbean. A search was structured to identify articles presenting strategies to approach the judicialization of health. A survey was designed, which included actors of the health system and judiciary sector. We prioritized the strategies qualified by more than the 50.0% of the participants as "very relevant". Strategies were categorized according to: governance, provision of services, human resources, information systems, financing, and medical products. We included 64 studies, which identified 50 strategies, related to the sub-functions and components of health systems. Of the 165 people who answered the survey, 80.0% were aged 35-64 years. The distribution of men and women was homogeneous. Half of the respondents were from Colombia (20.0%), Uruguay (16.9%), and Argentina (12.7%). We prioritized strategies that addressed aspects of generation of useful scientific evidence for decision making according to the health needs of the population, empowerment for the society, and creating spaces for discussion of measures of inclusion or exclusion of health technologies. The executive and judiciary decision makers prioritized questions that dealt with strategies that would ensure accountability. The results of this study contribute to the identification of effective strategies to approach the phenomenon of judicialization of health, guaranteeing the right to health.

Montoya-Ruiz, Carolina; Diaz, Francisco J.; Rodas, Juan D.

2014-01-01

Hantaan virus was discovered in Korea during the 1970s while other similar viruses were later reported in Asia and Europe. There was no information about hantavirus human infection in the Americas until 1993 when an outbreak was described in the United States. This event promoted new studies to find hantaviruses in the Americas. At first, many studies were conducted in Brazil, Argentina, Chile, Uruguay and Paraguay, while other Latin American countries began to report the presence of these agents towards the end of the 20th century. More than 30 hantaviruses have been reported in the Western Hemisphere with more frequent cases registered in the southern cone (Argentina, Chile, Uruguay, Paraguay, Bolivia and Brazil). However there was an important outbreak in 2000 in Panama and some rare events have been described in Peru, Venezuela and French Guiana. Since hantaviruses have only recently emerged as a potential threat in the tropical zones of the Americas, this review compiles recent hantavirus reports in Central America, the Caribbean islands and the northern region of South America. These studies have generated the discovery of new hantaviruses and could help to anticipate the presentation of possible future outbreaks in the region. PMID:24638203

Background Incorporation of molecular analysis of the epidermal growth factor receptor (EGFR) gene into routine clinical practice represents a milestone for personalized therapy of the non-small-cell lung cancer (NSCLC). However, the genetic testing of EGFR mutations has not yet become a routine clinical practice in developing countries. In view of different prevalence of such mutations among different ethnicities and geographic regions, as well as the limited existing data from Latin America, our aim was to study the frequency of major types of activating mutations of the EGFR gene in NSCLC patients from Uruguay. Methods We examined EGFR mutations in exons 18 through 21 in 289 NSCLC Uruguayan patients by PCR-direct sequencing. Results EGFR mutations were detected in 53 of the 289 (18.3%) patients, more frequently in women (23.4%) than in men (14.5%). The distribution by exon was similar to that generally reported in the literature. Conclusions This first epidemiological study of EGFR mutations in Uruguay reveals a wide spectrum of mutations and an overall prevalence of 18.3%. The background ethnic structure of the Uruguayan population could play an important role in explaining our findings. PMID:28744312

The identity of Hyla leucotaenia Burmeister, 1861 (Anura: Hylidae).

PubMed

Pinheiro, Paulo D P; Faivovich, Julián; Langone, José A; Kwet, Axel

2014-11-13

The German naturalist Carl Hermann Conrad Burmeister (1807-1892) had a prolific scientific career, spanning multiple taxa from diverse insect groups and trilobites to temnospondyls, birds, and extant and fossil mammals (see Berg, 1895). His contributions to anuran taxonomy are concentrated in two books, "Erläuterungen zur Fauna Brasiliensis…" (Burmeister, 1856) and "Reise durch die La Plata-Staaten…" (Burmeister, 1861). The latter is an account of his travels in Argentina and Uruguay from 1857-1860 and includes descriptions of three new species of frogs: Leiuperus nebulosus, Cystignathus mystacinus, and Hyla leucotaenia. While the first two names currently designate valid species, with the combinations Pleurodema nebulosum and Leptodactylus mystacinus respectively, the last name has had a more complex taxonomic history. It involves confusions involving a homonym, its consideration as a junior synonym of Hypsiboas pulchellus (Duméril & Bibron, 1841)-a widely distributed species in eastern Argentina, southeastern Brazil, and Uruguay (Frost, 2014)-and its actual identity corresponding to another widespread species in the same geographic area, with which it has never before been associated: Scinax squalirostris (A. Lutz, 1925). All these issues are discussed in this paper.

Silversides (Odontesthes bonariensis) reside within freshwater and estuarine habitats, not marine environments

Avigliano, Esteban; Miller, Nathan; Volpedo, Alejandra Vanina

2018-05-01

Otolith core-to-edge Sr:Ca ratio was determined by laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) to analyze the salinity-habitat migration history of the silverside, Odontesthes bonariensis, within the Uruguay River (freshwater) and Río de la Plata Estuary (estuarine water) (Plata Basin, South America). Regular core-to-edge oscillations in Sr:Ca suggest that the silverside makes annual migrations between freshwater (<1 PSU) and brackish (>1 PSU) habitats, with no evidence of marine incursion or non-migratory individuals. Empirical equations that represent the relationship between conductivity/salinity and otolith Sr:Ca ratio were used to identify where in an otolith an individual transitioned between freshwater and brackish habitats. In most specimens, the first migration between habitats likely occurred within the first year of life. Average numbers of changes between stable Sr:Ca signatures (sites with different salinities) determined by Change-Point analysis were similar from Uruguay River (8.9 ± 3.7) and Río de la Plata Estuary (7.5 ± 2.5) for comparable age fish (p < 0.05), suggesting that habitat use is similar in both collection sites.

Objectives. We examined pregnant women's use of cigarettes and other tobacco products and the exposure of pregnant women and their young children to secondhand smoke (SHS) in 9 nations in Latin America, Asia, and Africa. Methods. Face-to-face surveys were administered to 7961 pregnant women (more than 700 per site) between October 2004 and September 2005. Results. At all Latin American sites, pregnant women commonly reported that they had ever tried cigarette smoking (range: 78.3% [Uruguay] to 35.0% [Guatemala]). The highest levels of current smoking were found in Uruguay (18.3%), Argentina (10.3%), and Brazil (6.1%). Experimentation with smokeless tobacco occurred in the Democratic Republic of the Congo and India; one third of all respondents in Orissa, India, were current smokeless tobacco users. SHS exposure was common: between 91.6% (Pakistan) and 17.1% (Democratic Republic of the Congo) of pregnant women reported that smoking was permitted in their home. Conclusions. Pregnant women's tobacco use and SHS exposure are current or emerging problems in several low- and middle-income nations, jeopardizing ongoing efforts to improve maternal and child health.

Susceptibility to the type 1 diabetes is genetically controlled and there is an increased risk associated with the presence of some specific alleles of the human leukocyte antigens class II loci (DQA1 and DQB1 genes). The purpose of this study is to evaluate the association between type 1 diabetes and HLA DQ alleles using case-parents trios in the admixed population of Uruguay composed by a mixture of Caucasian, Amerindian and Negroid populations. DQA1 and DQB1 genotyping was performed by polimerase chain reaction followed by oligospecific probes hybridization in 51 case-parents trios. The transmission disequilibrium test was used for detecting differential transmission in the HLA DQ loci. DQB1*0302 was the only allele for which preferential transmission is suggested (probability of transmission = 67.56%; exact p-value TDT = 0.047 uncorrected for multiple comparisons). DQA1*0301 allele showed a trend for preferential transmission without achieving statistical significance. This result would confirm the hypothesis previously advanced in a case-control study. Therefore, DQB1*0302 allele could be considered as the most important susceptibility allele for developing type 1 diabetes in Uruguay population.

Hantaan virus was discovered in Korea during the 1970s while other similar viruses were later reported in Asia and Europe. There was no information about hantavirus human infection in the Americas until 1993 when an outbreak was described in the United States. This event promoted new studies to find hantaviruses in the Americas. At first, many studies were conducted in Brazil, Argentina, Chile, Uruguay and Paraguay, while other Latin American countries began to report the presence of these agents towards the end of the 20th century. More than 30 hantaviruses have been reported in the Western Hemisphere with more frequent cases registered in the southern cone (Argentina, Chile, Uruguay, Paraguay, Bolivia and Brazil). However there was an important outbreak in 2000 in Panama and some rare events have been described in Peru, Venezuela and French Guiana. Since hantaviruses have only recently emerged as a potential threat in the tropical zones of the Americas, this review compiles recent hantavirus reports in Central America, the Caribbean islands and the northern region of South America. These studies have generated the discovery of new hantaviruses and could help to anticipate the presentation of possible future outbreaks in the region.

2014-03-14

In the last three decades some faunal surveys of Drosophilidae have been done in several environments in the Neotropical region, especially in Brazil. But approximately 30 to 50% of the drosophilids in Brazil have not yet been described, and the degradation of some biomes causes a profound loss of species diversity, as well as the loss of information about the present structureof their communities. This is the situation with the pampas biome, which covers southernmost Brazil, all of Uruguay, and the central region of eastern Argentina. For the present study, seasonal collections were made in a natural area of pampas within the limits of the municipality of Bossoroca in the state of Rio Grande do Sul, Brazil (28°45'01"S 54°56'55"W), from April 2011 to April 2012. A total of 7,164 drosophilids of 51 species were collected, comprising 36 species belonging to Drosophila Fallén, ten of Rhinoleucophenga Hendel, two of Amiota Loew, two of Zygothrica Wiedemann and one of Zaprionus Coquillett. Some species were recorded for the first time in pampas: Drosophila briegeri Pavan & Breuer, D. fuscolineata Duda, Rhinoleucophenga obesa (Loew), R. punctulata Duda, R. subradiata Duda and Zygothrica orbitalis (Sturtevant). Furthermore, three new species of genus Rhinoleucophenga were described: R. pampeana sp. nov., R. missionera sp. nov. and R. sulina sp. nov. A dichotomous key is given for the Rhinoleucophenga species recorded in pampas. An intensive literature search is reviewed of drosophilid species recorded in pampas of Brazil, Uruguay and Argentina, including taxonomic, genetic, evolutionary, and ecological studies. Despite Brazilian pampas being the richest when compared with Uruguay and Argentina, the three countries presented the same problem: huge areas with a barely surveyed Drosophilidae fauna. The combination of this information and the knowledge of the current state of preservation of pampas stress the necessity and importance of creating new conservation areas to

The primary aim of this survey was to report total fluid intake (TFI) and different fluid types for children (4-9 years) and adolescents (10-17 years) in Mexico, Brazil, Argentina and Uruguay. The second aim was to compare TFI with the adequate intake (AI) of water from fluids as recommended by the USA Institute of Medicine. Data were collected using a validated liquid intake 7-day record (Liq.In 7 ). Participants' characteristics, including age, sex and anthropometric measurements were recorded. A total of 733 children and 933 adolescents were recruited. Over 75% of children in Uruguay met the IOM's recommended intake. Fewer children in Argentina (64-72%) and Brazil (41-50%) obtained AI and the lowest values were recorded in Mexico (33-44%), where 16% of boys and 14% girls drank 50% or less of the AI. More adolescents in Argentina (42%) met the AIs than other countries; the lowest was in Mexico (28%). Children and adolescents in Mexico and Argentina drank more sugar sweetened beverages than water. Large numbers of children and adolescents did not meet AI recommendations for TFI, raising concerns about their hydration status and potential effects on mental and physical well-being. Given the negative effects on children's health, the levels of SSB consumption are worrying.

Carbon and Nutrient Cycling in the Southwestern Atlantic Ocean

State of Knowledge on the Southwestern Atlantic Ocean Margin; Montevideo, Uruguay, 16-22 November 2008; The southwestern Atlantic Ocean margin (SWAOM), along the coasts of southern Brazil, Uruguay, and Argentina, is one of the most productive regions of the world ocean and is believed to be the largest carbon dioxide (CO2) sink in the Atlantic Ocean. The region is dominated by two major boundary currents (the Brazil and the Malvinas), which impinge on a broad continental shelf along southeastern South America and converge offshore of the Rio de la Plata, the largest source of freshwater to the South Atlantic Ocean. Scientific knowledge about this region is based on past research focused generally on processes within the confines of the waters of the individual countries and from single disciplines. However, the complex interactions of physical, chemical, and biological processes that control the transport and production in time and space across this region require multidisciplinary investigation and international cooperation. This led a group of more than 40 marine scientists from these countries and the United States to convene a workshop to review what is known about this region, to suggest how future multidisciplinary research might be organized, and to foster regional and North-South scientific cooperation.

Data are conflicting regarding the effect of professional staff attire on children at pediatric dental clinics. To compare the preferences of children and their parents in three countries, regarding the gender and attire of pediatric dentists. A multi-centered study was conducted in pediatric dental clinics in Israel (N=100), Uruguay (N=270) and Spain (N=200). Children, aged 4-12 years, and their parents were asked to choose the pediatric dentist they preferred from 5 pictures of the same male and 5 pictures of the same female, in different attire. In Israeli clinics, where half of the pediatric dentists were male, and they wore white coats or casual attire, these were preferred by children, with no preference regarding the dentist's gender. In Spain, where the majority of dentists were females, wearing surgical scrubs, children preferred female dentists with this attire. In Uruguay, where female dentists wore surgical or pediatric scrubs, these were preferred by children. Parents more often selected female than male dentists; they preferred pediatric scrubs for their children's dentists more often than their children preferred such attire. Children's preferences for the attire of pediatric dentists reflected the common wearing apparel for dentists at the clinics they attended.

To learn about parental decisions to abort or continue a pregnancy after prenatal diagnosis of chromosomal abnormalities among the population in Uruguay. Between 1982 and 2003, 14 656 amniocentesis and 2740 chorionic villus samplings were performed in a referral Genetic Unit. Chromosomal anomalies were found in 376 cases (2.16%) and included Down syndrome, aneuploidies in which a severe prognosis was expected, sex chromosome aneuploidy and aneuploidies with a low risk of an abnormal clinical phenotype. The couples that received abnormal results were contacted by phone and asked if they had continued or interrupted the pregnancy after the diagnosis and genetic counseling. We contacted 207 couples (55%). When confronted with Down syndrome or an aneuploidy in which a severe prognosis was expected, 89% and 96% of patients, respectively, decided to terminate the pregnancy. When confronted with sex chromosome aneuploidy or aneuploidies with a low risk of an abnormal clinical phenotype, 79% and 90% of patients, respectively, decided to continue the pregnancy. The present study shows that when faced with an anomaly such as Down syndrome and aneuploidies in which a severe prognosis was expected, most of the couples decided to terminate the pregnancy, although TOP is not legally available in Uruguay.

New human polyomaviruses have been described in the last years, including the Merkel-cell polyomavirus (MCPyV; Human polyomavirus 5) and the Human polyomavirus 6 (HPyV6). Although their infection is usually asymptomatic, in immunocompromised host can cause life-threatening pathologies, such as the Merkel cell carcinoma, an aggressive skin neoplasia associated to the MCPyV. Despite being prevalent viruses in population, epidemiological data from South America are scarce, as well as the characterization of the viral types circulating and their origin. The aims of this work were to describe MCPyV and HPyV6 from environmental samples with different geographical origin and to analyze their phylogenetic and evolutionary histories, particularly for MCPyV. Partial and complete genome sequences were obtained from sewage samples from Argentina, Uruguay and Spain. A total number of 87 sequences were obtained for MCPyV and 33 for HPyV6. Phylogenetic analysis showed that MCPyV sequences distributed according to their geographic origin in Europe/North America, Africa, Asia, South America and Oceania groups, suggesting that viral diversification might have followed human migrations across the globe. In particular, viruses from Argentina associated with Europe/North America and South America genotypes, whereas those from Uruguay and Spain also grouped with Africa genotype, reflecting the origin of the current population in each country, which could arrive not only during ancient human migration but also during recent migratory events. In addition, the South American group presented a high level of clusterization, showing internal clusters that could be related to specific locations, such as French Guiana and Brazil or the Southern region into South America, such as Argentina and Uruguay, suggesting a long term evolutionary process in the region. Additionally, in this work, we carried out the first analysis about the evolutionary history of MCPyV trough the integration of

Forensic anthropology has been one of the fastest growing medico-legal disciplines both in its contribution to the practical needs of the legal system and research accomplishments. New anthropological standards were developed to apply to a specific population of a region. The purpose of this paper is to analyze a large sample of anthropological forensic cases and to review pertinent literature that deals with anthropological standards developed for the population of the continent of Central and South America. Using Uruguay as an example, there was not a single office or anthropologist assigned to analyze human skeletal remains in Uruguay. In 1991 the Laboratorio de Antropología Forense at the Morgue Judicial of Montevideo was created. A total of 189 forensic anthropological cases (276 individuals) were analyzed since this date. Twenty six percent of cases involving human remains were positively identified. The majority came from the Departamento de Montevideo, the largest population district of the country. Most of the cases fell into the 60 to 69 years old age range (35%). Females represented 32% of the total. Since the establishment of the laboratory, the number of forensic cases increased considerably from 20 in 1991 to 40 in 1997. The case studies were accompanied with skull-photo superimposition and facial reconstruction when no other evidence for positive identification was available. This service provided by the laboratory was quickly known to coroners, law enforcement agencies, and other legal authorities and thus utilized not only in Uruguay but also in several other countries in the continent. Because of the obvious need for an anthropologist, there are now university programs to provide forensic anthropological education. Yet, research has lagged behind considerably. Deficiencies are obvious in basic osteological standards of estimating age, calculating stature, determining sex and assessing race that can be applied to populations of the continent

Resumen Introducción: Analizar y describir los parámetros sagitales espinales y pelvianos de una serie de 100 voluntarios argentinos. Métodos: Se realizaron prospectivamente espinogramas digitalizados de perfil a 100 voluntarios (30 hombres y 70 mujeres), con un promedio de edad 34,14 años. Todos los voluntarios eran asintomáticos al momento de realizarse el estudio. Los espinogramas se hicieron en un equipo Kodak Elite CR. Se realizaron las mediciones usando el software Surgimap®, versión 2.2.9.9.2. Se tomaron los siguientes parámetros: C7 SVA, C2-C7 CL, TK, LL, TPA, T1 tilt, PI, PT, SS, ángulo L4-S1, ángulo L1-L4, PI-LL y CTPA. Los datos fueron analizados empleando el paquete estadístico Medcalc 11.2. Se determinaron las estadísticas descriptivas adecuadas para cada variable según su escala de medición y distribución. Se realizó la estimación de intervalos de referencia del 95% y de intervalos de confianza del 95% para todas las variables. Así, el nivel de significación obtenido fue igual a 0.05. Se dividió a los voluntarios según la clasificación morfométrica de Roussouly en cuatro tipos. Resultados: El promedio para cada variable fue CL −10.04, TK 30.14, T1SPi −6.5, L1-L4 −12.45, L4-S1 −46.16, CTPA 2.5, TPA 4.65, PT 11.22, PI 48.04, LL −59.10, PI-LL −11.11, C7 SVA mm −23.68. Los ±2 desvíos estándar para cada variable fueron: CL (−33.26, 13.12); TK (17.15, 43.30); T1SPi (−11.78, −1.25), L1-L4 (−25.55, 0.25), L4-S1 (−64.44, −27.55), CTPA (0.33, 4.80), TPA (−8.64, 18.22), PT (−1.99, 24.75), PI (25.23, 71.44), LL (−78.74, −39.89), PI-LL (−29.10, 7.04), C7 SVA mm (−79.45, 32.08).

Candida parapsilosis is a human commensal yeast, frequently involved in infection worldwide and especially in neonates. It is the second species responsible for bloodstream infections in Uruguay and the third species in France. We were interested in knowing whether the population structure of isolates responsible for candidemia in France and in Uruguay was different. Genotyping methods based on microsatellite length polymorphism (MLP) have been described and are especially used for investigation of local outbreaks. We therefore determined the genotypes of 159 C. parapsilosis isolates recovered from 122 patients (84 French patients from 43 hospitals and 38 Uruguayan patients from 10 hospitals) using three microsatellites markers previously described. Our results confirmed that C. parapsilosis population has a high genetic diversity, clonal inheritance and that majority of patients were infected by a single isolate. But we described recurrent infections due to related or unrelated genotypes resulting from isolates harboring loss or gain of heterozygosity. We also described three cases of coinfections due to unrelated genotypes. We did not uncover geographic specificity but observed two linked genotypes that seem to be associated with voriconazole resistance. Finally, among eight isolates involved in grouped cases, the genotypes were similar in six cases supporting the hypothesis of inter-patient transmission. These results confirmed the usefulness of performing MLP genotyping analysis for grouped cases of C. parapsilosis isolates in order to reinforce preventive hygiene measures.

Reasons for sperm banking, patient age, pre-freeze and post-thaw semen parameters, and recovery rates were analyzed. Results 623 samples were cryobanked between 2013 and 2015. Only 324 samples were considered for analysis after selection based on inclusion criteria. In most cases the samples were stored because the patients were undergoing assisted reproductive technology (ART) treatment (n=190; 58,64%) or for oncological reasons (n=113; 34,88%). The median age of bankers was 34 years. In the cancer group, 61.95% (n=70) of the subjects had been diagnosed with testicular cancer. Medians of semen parameters for both groups were above the lower reference limits dictated by the World Health Organization (2010). In fresh samples, a significant difference was observed in progressive motility (47% vs. 56%) between ART and oncological patients. After thawing, total motility (27% vs. 32%), progressive motility (19% vs. 22%), and vitality (48% vs. 56%) differed significantly between ART and oncological bankers. Conclusion Semen banking has been performed successfully in Uruguay and outcomes are on par with international standards. Surprisingly, the semen parameters of the cancer group were nearly normal.

The impact of health technology assessment (HTA) in the judicialization of the right of health has not been deeply studied in Latin American countries. The purpose of this study is to review the process of judicialization of the access to high cost drugs in Uruguay and assess the impact HTAs have had on this process. The methodology used for this study included a comprehensive literature search in electronic databases, local journals, internal documents developed in the Ministry of Health, as well as conducting interviews with key informants. Judicialization of the access of high cost drugs has been increasing since 2010. The strategy of the Ministry of Health of Uruguay to decrease this problem included the organization of roundtables with judges and other stakeholders on the basis of HTA, the training of defense lawyers in the use and interpretation of HTA, and the participation of a professional who develops HTA in the preparation of the defense arguments. A year after the implementation of this strategy, 25 percent of writs of protection were won by the Ministry of Health. Even though the strategy implemented was effective in reducing the loss of litigations, it was not effective in reducing the growing number of writs of protection. It is essential to address this problem in a broad debate and to promote understanding between the parties.

Mating partners need to recognize, assess each other, and exchange information through behavioral events that occur before, during, and after mating. Sexual signals, as well as life history traits, are influenced by selective pressures and environmental factors that can vary across distant geographical areas. Allocosa senex is a sand-dwelling wolf spider which constructs burrows along the sandy coasts of Argentina, Brazil, and Uruguay. Females are the mobile sex that searches for males and initiates courtship. They prefer males which construct longer burrows, and males prefer virgin females in good body condition. The objective of this study was to compare sexual behavior patterns, as well as body characteristics and burrow dimensions, between two geographically distant locations of A. senex, one in Uruguay (Uruguayan location) and the other from central Argentina (Argentinean location). We found differences in the number of male abdominal vibrations, male and female touches during mating, and number of erections of male leg spines, which all were higher in matings of Argentinean pairs. On the other hand, male body mass and female body condition were higher in Uruguayan individuals. The wide distribution of A. senex could be determining variations in the biotic and abiotic features that affect the species, generating differences in the strength of selective forces acting on individuals from the two studied locations.

In this study, we searched for extended-spectrum β-lactamases (ESBLs), class 1 and 2 integrons, and qnrA, qnrB and qnrS genes in 56 oxyimino-cephalosporin and/or ciprofloxacin-resistant enterobacterial isolates obtained from the gastrointestinal tract of patients admitted in an Intensive Care Unit in Uruguay. ESBLs were detected in 11 isolates (6 CTX-M-2, 3 CTX-M-9, 1 CTX-M-15 and 1 PER-2). qnr genes and integrons were detected in 5 and 24 isolates, respectively. Eight different antibiotic resistance gene cassettes were found within six different genetic arrangements. Two types of complex class 1 integrons carrying insertion sequence ISCR1 were found, one showing bla(CTX-M-2)-orf3 and the other qnrA1-ampR. Ten of the thirteen isolates carrying class 2 integrons presented the element IS5 inserted between intI2 and dfrA1, whereas another class 2 integron lacked the internal stop codon usually present in intI2. This is the first report of the occurrence of qnrA, qnrB and bla(CTX-M-9) in Uruguay. Dissemination of the different groups of CTX-M enzymes (i.e. groups 1, 2 and 9) appears to be a recent phenomenon in South America.

Hemoglobinopathies are the most common recessive diseases worldwide but their prevalence in Uruguay has not been investigated. In this study, 397 unrelated outpatient children from the Pereira Rosell Hospital Center (CHPR), as well as 31 selected patients with microcytic anemia and 28 β-thalassemia carriers were analyzed for hemoglobinopathies by using biochemical and molecular biology methods. Parametric and non-parametric methods were used to compare the hematological indices between groups of genotypes. Of the 397 patients in the first group, approximately 1% (0.76% HbS and 0.25% β-thalassemia) had a mutation in the HBB gene and 3.3% had β-thalassemia. These mutations had a heterogeneous distribution that varied according to individual ancestry. HbS was found exclusively in individuals with declared African ancestry and had a carrier frequency of 2.2%. The frequency of α-thalassemia carriers in outpatients of European and African ancestry was 1.2% and 6.5%, respectively. In contrast, the frequency of α-thalassemia carriers in patients with microcytic anemia was 25.8%, significantly higher (p < 0.01) than that observed in the sample as a whole and in Afro-descendants and Euro-descendants. Significant differences were observed in the hematological parameters between individuals with thalassemia genotypes and those with a normal genotype. These results indicate that hemoglobinopathies are a relevant health problem in Uruguay. PMID:24130436

The First Conference of the Latin America Chapter of the Cell Stress Society International (CSSI) organized by CSSI was held in Montevideo, Uruguay, on March 11-14, 2014. The Latin America Chapter of the CSSI (LAC-CSSI) was established at the Workshop on the Molecular Biology of the Stress Response, Porto Alegre, Brazil, May 2012. The chapter's first meeting took place in the beautiful city of Montevideo and was chaired by the first (LAC-CSSI) elected president Professor María Bausero. Forty-two invited speakers presented their work to more than 100 scientists. The first day of the conference was dedicated to an introductory program for students, young investigators, and participants new to the field of molecular chaperones and the stress response. These seminars were held in the Pasteur Institute of Montevideo and the Faculty of Sciences of the University of the Republic. These institutions were carefully selected to give foreign participants a broad view of the diversity of students and institutions doing research in Uruguay, as well as an opportunity for direct interaction with our scientists and students. Invited speakers for the seminar series were Dr. Wolfgang Schumann, Dr. Cristina Bonorino, Dr. Antonio De Maio, Dr. Ian Brown, Dr. Rafael Radi, Dr. Daniel Ciocca, and Dr. Celia Quijano. The remaining days of the conference took place at the Sheraton Hotel in Montevideo, and the scientific sessions are discussed below.

The rapid rise of phenotypic and ecological diversity in independent lake-dwelling groups of cichlids is emblematic of the East African Great Lakes. In this study, we show that similar ecologically based diversification has occurred in pike cichlids (Crenicichla) throughout the Uruguay River drainage of South America. We collected genomic data from nearly 500 ultraconserved element (UCEs) loci and >260 000 base pairs across 33 species, to obtain a phylogenetic hypothesis for the major species groups and to evaluate the relationships and genetic structure among five closely related, endemic, co-occurring species (the Uruguay River species flock; URSF). Additionally, we evaluated ecological divergence of the URSF based on body and lower pharyngeal jaw (LPJ) shape and gut contents. Across the genus, we recovered novel relationships among the species groups. We found strong support for the monophyly of the URSF; however, relationships among these species remain problematic, likely because of the rapid and recent evolution of this clade. Clustered co-ancestry analysis recovered most species as well delimited genetic groups. The URSF species exhibit species-specific body and LPJ shapes associated with specialized trophic roles. Collectively, our results suggest that the URSF consists of incipient species that arose via ecological speciation associated with the exploration of novel trophic roles. © 2017 European Society For Evolutionary Biology.

RESUMEN El presente artículo es una revisión sobre la contaminación del agua, el aire y el efecto del cambio climático en la salud de la población peruana. Uno de los principales contaminantes del aire es el material particulado menor de 2,5 μ (PM 2,5), en la ciudad de Lima, anualmente 2300 muertes prematuras son atribuibles a este contaminante. Otro problema es la contaminación del aire domiciliario por el uso de cocinas con combustible de biomasa, donde la exposición excesiva a PM 2,5 dentro de las casas es responsable de aproximadamente 3000 muertes prematuras anuales entre adultos, con otro número desconocido de muertes entre niños debido a infecciones respiratorias. La contaminación del agua tiene como principales causas los desagües vertidos directamente a los ríos, minerales (arsénico) de varias fuentes, y fallas de las plantas de tratamiento. En el Perú, el cambio climático puede impactar en la frecuencia y severidad del fenómeno de El Niño oscilación del sur (ENSO) que se ha asociado con un incremento en los casos de enfermedades como cólera, malaria y dengue. El cambio climático incrementa la temperatura y puede extender las áreas afectadas por enfermedades transmitidas por vectores, además de tener efecto en la disponibilidad del agua y en la contaminación del aire. En conclusión, el Perú, pasa por una transición de factores de riesgo ambientales, donde coexisten riesgos tradicionales y modernos, y persisten los problemas infecciosos y crónicos, algunos de los cuales se asocian con problemas de contaminación de agua y de aire.

este artículo discute brevemente la prevalencia de caries, la naturaleza multifactorial de su etiología, el riesgo de caries y el papel y eficacia del fluoruro. Resalta también la investigación sobre el metabolismo bacteriano, que ha aportado conocimientos sobre la defensa natural oral contra la caries y la base para el desarrollo de una nueva tecnología para la prevención diaria y el tratamiento de la caries. Por último, se resume la evidencia que respalda que la tecnología complementa y mejora la eficacia anti-caries de la crema dental con fluoruro. los datos globales muestran que a pesar de la exitosa introducción del fluoruro, la caries dental es una enfermedad prevalente. La experiencia de caries depende del balance entre el consumo de azúcares, la higiene oral y el uso del fluoruro. Hay tres conceptos científicos que son fundamentales en las nuevas mediciones para detectar, tratar y monitorear la caries: (1) la caries dental es un proceso dinámico, (2) la caries dental es un proceso continuo de etapas que van desde reversible (pre-clínica) hasta irreversible (lesiones clínicamente detectables), y (3) el proceso de la caries es un balance de factores patológicos y protectores que pueden modularse para el manejo de la caries. El fluoruro funciona como factor protector al detener y revertir el proceso de la caries, pero el fluoruro no previene los factores patológicos que inician el proceso. Se ha identificado una tecnología novedosa, basada en arginina y un compuesto insoluble de calcio, que está dirigida a la placa dental para prevenir la iniciación del proceso de caries al reducir los factores patológicos. Como los mecanismos de acción de la arginina y el fluoruro son altamente complementarios, se ha desarrollado un nuevo dentífrico que combina la arginina y el fluoruro, y se ha probado clínicamente que brinda una prevención superior contra la caries.

Acinetobacter baumannii has emerged as a serious problem in the hospital environment at a global scale. Previous results from our laboratory showed a high frequency of class 2 integrons in A. baumannii strains from Argentina regarding the low rate of this element in A. baumannii isolates from the rest of the world. To reveal the current epidemiology of class 2 integrons, a molecular surveillance analyzing 78 multidrug resistant (MDR) A. baumannii isolates from Argentina and Uruguay was performed, exposing the presence of class 2 integron in the 36.61% of the isolates. Class 2 integron characterization showed that the typical Tn7::In2-7 array was present in 26 out of 27 intI2 positive isolates. All intI2 positive isolates contained at least one of the Tn7 transposition genes. In addition, we identified that 18 intI2 positive isolates possessed the Tn7::In2-7 within the attTn7 site. The molecular typing evidenced that clones I and IV that do not belong to widespread European clones I and II were found among the intI2 positive isolates. Our results exposed the widely dissemination of class 2 integron among MDR A. baumannii isolates from Argentina and Uruguay, also showing the persistence of two novel clones in our region, which could explain in part the high frequency of class 2 integron found in our region.

Local trophic specialisation in a cosmopolitan spider (Araneae).

Trophic specialisation can be observed in species with long-term constant exploitation of a certain prey in all populations or in a population of a species with short-term exploitation of a certain prey. While in the former case the species would evolve stereotyped or specialised trophic adaptations, the trophic traits of the latter should be versatile or generalised. Here, we studied the predatory behavioural adaptations of a presumed myrmecophagous spider, Oecobius navus. We chose two distinct populations, one in Portugal and the other in Uruguay. We analysed the actual prey of both populations and found that the Portuguese population feeds mainly on dipterans, while the Uruguayan population feeds mainly on ants. Indeed, dipterans and springtails in Portugal, and ants in Uruguay were the most abundant potential prey. In laboratory trials O. navus spiders recognised and captured a wide variety of prey. The capture efficiency of the Portuguese population measured as components of the handling time was higher for flies than for ants, while that of the Uruguayan population was higher for ants. We found phenotypic plasticity in behavioural traits that lead to increased capture efficiency with respect to the locally abundant prey, but it remains to be determined whether the traits of the two populations are genetically fixed. We conclude that O. navus is a euryphagous generalist predator which shows local specialisation on the locally abundant prey. Copyright © 2012 Elsevier GmbH. All rights reserved.

Mapping of Chagas disease research: analysis of publications in the period between 1940 and 2009.

Publications are often used as a measure of success in research work. Chagas disease occurs in Central and Southern America. However, during the past years, the disease has been occurring outside Latin America due to migration from endemic zones. This article describes a bibliometric review of the literature on Chagas disease research indexed in PubMed during a 70-year period. Medline was used via the PubMed online service of the U.S. National Library of Medicine from 1940 to 2009. The search strategy was: Chagas disease [MeSH] OR Trypanosoma cruzi [MeSH]. A total of 13,989 references were retrieved. The number of publications increased steadily over time from 1,361 (1940-1969) to 5,430 (2000-2009) (coefficient of determination for linear fit, R²=0.910). Eight journals contained 25% of the Chagas disease literature. Of the publications, 64.2% came from endemic countries. Brazil was the predominant country (37%), followed by the United States (17.6%) and Argentina (14%). The ranking in production changed when the number of publications was normalized by estimated cases of Chagas disease (Panama and Uruguay), population (Argentina and Uruguay), and gross domestic product (Bolivia and Brazil). Several Latin American countries, where the prevalence of T. cruzi infection was not very high, were the main producers of the Chagas disease literature, after adjusting for economic and population indexes. The countries with more estimated cases of Chagas disease produced less research on Chagas disease than some developed countries.

Based on mitochondrial DNA (mtDNA), it has been estimated that at least 15 founder haplogroups peopled the Americas. Subhaplogroup C1d3 was defined based on the mitogenome of a living individual from Uruguay that carried a lineage previously identified in hypervariable region I sequences from ancient and modern Uruguayan individuals. When complete mitogenomes were studied, additional substitutions were found in the coding region of the mitochondrial genome. Using a complete ancient mitogenome and three modern mitogenomes, we aim to clarify the ancestral state of subhaplogroup C1d3 and to better understand the peopling of the region of the Río de la Plata basin, as well as of the builders of the mounds from which the ancient individuals were recovered. The ancient mitogenome, belonging to a female dated to 1,610±46 years before present, was identical to the mitogenome of one of the modern individuals. All individuals share the mutations defining subhaplogroup C1d3. We estimated an age of 8,974 (5,748–12,261) years for the most recent common ancestor of C1d3, in agreement with the initial peopling of the geographic region. No individuals belonging to the defined lineage were found outside of Uruguay, which raises questions regarding the mobility of the prehistoric inhabitants of the country. Moreover, the present study shows the continuity of Native lineages over at least 6,000 years. PMID:26509686

Over the last decade, Uruguay has expanded and intensified its rainfed crop production. This process has affected beekeeping in several ways: for example, by reducing the space available. This has increased the density of apiaries, the risk of varroosis and acaricide use. Additionally, the dominance of no-tillage crops has increased the frequencies of application and of loads of pesticides in regions where such crops share the land with beekeeping and honey production. Therefore, the exposure of bees to xenobiotics (agricultural pesticides and veterinary products) has increased in line with pollution of hives and their products. To document pollution from hive exposure to pesticides, we surveyed the presence of 30 xenobiotics normally used in Uruguay, in recycled beeswax (RB) and in honey cappings (HC) from the main Uruguayan beekeeping regions. There was contamination of all the analyzed samples (RB and HC) with the herbicide atrazine at a range of 1-2 ng g -1 . At least three or four additional xenobiotics were detected: insecticides (chlorpyrifos-ethyl and thiacloprid); fungicides (azoxystrobin and tebuconazole); and veterinary products (coumaphos, ethion, and tau-fluvalinate). The frequency of detection of chlorpyrifos-ethyl and coumaphos in RB samples was higher than in those of HC. Moreover, the concentrations of azoxystrobin, coumaphos, and tebuconazole in RB samples were higher than in HC samples. Therefore, we suggest the use of HC to produce recycled printed beeswax films for use in hives to minimize pollution transfer. Copyright © 2017 Elsevier Ltd. All rights reserved.

Environmental sustainability of South American rainfed agroecosystems is of current concern. In this work, we evaluate the occurrence of multiple pesticide residues in muscle tissue of wild fish species from two large rivers in South America (Uruguay and Negro Rivers). Two sampling campaigns (representing summer and winter crops) were performed during 2015 targeting a wide biodiversity of fish species used for human consumption (ranging from migratory to non-migratory and from detritivorous to top-predators). Three different localities associated to rainfed agriculture were assessed, two of them enclosed to a RAMSAR site (National Park "Esteros de Farrapos e Islas del Rio Uruguay"). Pesticide residues occurred in muscle tissue of 143 from 149 sampled fishes (96%). Thirty different pesticides were detected at concentrations from <1 to 194μgkg -1 . Incidence of pesticides in fish were tightly related to: i) features of the contaminant: (Kow, environmental persistence and mobility) and ii) intensity of use of particular pesticides and land dedicated to rainfed agriculture. Trifloxystrobin, metolachlor and pyraclostrobin showed the highest rates of occurrence. Of great concern is that strobirulins have highest toxicity to fish from those detected compounds. From the pattern of pesticides occurring for non-migratory fish species it was possible to trend important spatial differences related to the intensity of rainfed agriculture. Results suggest a regular exposition of aquatic wild biota to sublethal concentrations of multiple semi-polar pesticides. Copyright © 2018 Elsevier B.V. All rights reserved.

Does Multi-morbidity Mediate the Effect of Socioeconomics on Self-rated Health? Cross-country Differences

Assari, Shervin; Lankarani, Maryam Moghani

2015-01-01

Background: This study explored cross-country differences in how multi-morbidity explains the effects of socioeconomic characteristics on self-rated health. Methods: The study borrowed data from the Research on Early Life and Aging Trends and Effects. Participants were 44,530 individuals (age > 65 years) who were sampled from 15 countries (i.e. United States, China, India, Russia, Costa Rica, Puerto Rico, Mexico, Argentina, Barbados, Brazil, Chile, Cuba, Uruguay, Ghana and South Africa). Multi-morbidity was measured as number of chronic medical conditions. In Model I, main effects of socioeconomic factors on self-rated health were calculated using country-specific logistic regressions. In Model II, number of chronic conditions were also added to the models to find changes in coefficients for demographic and socioeconomic factors. Results: In the United States, number of chronic medical conditions explained the effect of income on subjective health. In Puerto Rico, number of chronic medical conditions explained the effect of marital status on subjective health. In Costa Rica, Argentina, Barbados, Cuba, and Uruguay, number of chronic medical conditions explained gender disparities in subjective health. In China, Mexico, Brazil, Russia, Chile, India, Ghana and South Africa, number of chronic medical conditions did not explain the effect of demographic or socioeconomic factors on subjective health. Conclusions: Multi-morbidity explains the effect of demographic and socioeconomic factors on subjective health in some but not other countries. Further research is needed. PMID:26445632

The reach of Spanish-language YouTube videos on physical examinations made by undergraduate medical students

This study was conducted to evaluate the performance and reach of YouTube videos on physical examinations made by Spanish university students. We analyzed performance metrics for 4 videos on physical examinations in Spanish that were created by medical students at Miguel Hernández University (Elche, Spain) and are available on YouTube, on the following topics: the head and neck (7:30), the cardiovascular system (7:38), the respiratory system (13:54), and the abdomen (11:10). We used the Analytics application offered by the YouTube platform to analyze the reach of the videos from the upload date (February 17, 2015) to July 28, 2017 (2 years, 5 months, and 11 days). The total number of views, length of watch-time, and the mean view duration for the 4 videos were, respectively: 164,403 views (mean, 41,101 views; range, 12,389 to 94,573 views), 425,888 minutes (mean, 106,472 minutes; range, 37,889 to 172,840 minutes), and 2:56 minutes (range, 1:49 to 4:03 minutes). Mexico was the most frequent playback location, followed by Spain, Colombia, and Venezuela. Uruguay, Ecuador, Mexico, and Puerto Rico had the most views per 100,000 population. Spanish-language tutorials are an alternative tool for teaching physical examination skills to students whose first language is not English. The videos were especially popular in Uruguay, Ecuador, and Mexico. PMID:29278903

Research on the relative influence of package features on children's perception of food products is still necessary to aid policy design and development. The aim of the present work was to evaluate the relative influence of two front-of-pack (FOP) nutrition labelling schemes, the traffic light system and Chilean warning system, and label design on children's choice of two popular snack foods in Uruguay, wafer cookies and orange juice. A total of 442 children in grades 4 to 6 from 12 primary schools in Montevideo (Uruguay) participated in the study. They were asked to complete a choice-conjoint task with wafer cookies and orange juice labels, varying in label design and the inclusion of FOP nutrition information. Half of the children completed the task with labels featuring the traffic-light system (n = 217) and the other half with labels featuring the Chilean warning system (n = 225). Children's choices of wafer cookies and juice labels was significantly influenced by both label design and FOP nutritional labels. The relative impact of FOP nutritional labelling on children's choices was higher for the warning system compared to the traffic-light system. Results from the present work stress the need to regulate the design of packages and the inclusion of nutrient claims, and provide preliminary evidence of the potential of warnings to discourage children's choice of unhealthful products.

To analyze the evolution of the prevalence of tobacco use, comparing data obtained from the Global Youth Tobacco Survey in 2007 and 2014 editions. Data from the World Youth Tobacco Survey 2007 and 2014 were compared. Tobacco control measures implemented in the period under review were also analyzed. Data shows a decrease in 30-day cigarette consumption in population aged 13 to 15 years: from 20.2% in 2007 to 8.2% in 2014. No significant differences were found between the sexes. Susceptibility to become a smoker in the next year decreased from 25.8% in 2007 to 16.6% in 2014. The implementation, almost simultaneously, of measures included in WHO Framework Convention for Tobacco Control, is an effective strategy to achieve the objectives of reducing the prevalence of tobacco use.

Protection from secondhand smoke (SHS) is one of the fundamental principles of the WHO Framework Convention for Tobacco Control. Objective data on SHS exposure in vehicles in South America is scarce. This study aimed to estimate prevalence of smoking inside vehicles. The point prevalence of smoking in vehicles was observed, and a method for estimating smoking prevalence was piloted. We observed 10 011 vehicles. In 219 (2.2%; 95% CI 1.91 to 2.49) of them, smoking was observed, and in 29.2% of these, another person was exposed to SHS. According to the 'expansion factor' we constructed, direct observation detected one of six to one to nine vehicles in which smoking occurred. The observed prevalence of smoking in vehicles (2.2%) could reflect a real prevalence between 12% and 19%. In 29.2% (95% CI 23.6 to 35.5) and 4.6% (95% CI 2.2 to 8.3) of vehicles in which smoking was observed, another adult or a child, respectively, was exposed to SHS. Smoking was estimated to occur in 12%-19% of vehicles, with involuntary exposure in one of three of vehicles observed. These data underscore a need for new public policies to eliminate SHS in vehicles to protect public health. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Ticks exotic for the Neotropical region were found on Python regius imported into Argentina and Chile. All ticks (7 males and 3 females) were classified as Amblyomma latum Koch, 1844 ( = Aponomma latum). Additionally, four lots comprising 18 males of the Argentinean tortoise tick, Amblyomma argentinae Neumann, 1904, were found on a terrestrial tortoise, Chelonoidis chilensis, and on three terrestrial tortoises (probably C. chilensis) imported to Uruguay presumably from Argentina). These findings alert us to the risk of expanding the distribution of reptile parasites and their diseases into regions previously free of these parasites.

El proposito de esta investigacion, un estudio cualitativo de caso, fue comparar y contrastar el curriculo vigente de la Escuela de Optometria de la UIAPR con las competencias y estandares requeridos por las agencias de acreditacion y de revalida. Con este proposito, decidimos realizar una revision y un analisis de documentos: el prontuario de cada uno de los cursos de los curriculos implantados en el 1993 y en el 2001; las competencias y estandares establecidos por las agencias de revalida y de acreditacion; y las estadisticas en las que se analiza el porcentaje de estudiantes que aprueban cada una de las partes de los examenes de revalida entre el 1998 al 2003. Se realizaron entrevistas dirigidas para dar apoyo y complementar la revision y el analisis de estos documentos. Los participantes de las entrevistas fueron tres estudiantes de la clase de optometria del 2004 (ultima clase del curriculo del 1993); tres estudiantes de la clase de optometria del 2005 (primera clase graduanda del curriculo vigente) y tres profesores y/o directores de los Departamentos de Ciencias Basicas, Ciencias Clinicas y Cuidado al Paciente. Esta investigacion se enmarco en el modelo de evaluacion curricular de discrepancia de Malcolm Provus y en el modelo de desarrollo basado en competencias. Uno de los hallazgos mas importantes del estudio es que los cambios que se implantaron al curriculo del 2001 no han logrado que los estudiantes mejoren su ejecucion en los examenes de revalida. Por otro lado, se encontro que el curriculo vigente atiende completamente los estandares de la practica de Optometria, pero no las competencias. Esta informacion fue validada mediante el uso de una tabla de cotejo para el analisis de los cursos y de la informacion obtenida de las entrevistas. El estudio determina y concluye que existen discrepancias entre los prontuarios de los cursos del curriculo y las competencias requeridas por la agencia de revalida.

Collections of Amblyomma auricularium (Conil 1878) and A. pseudoconcolor Aragão, 1908 are discussed in relation to distribution and hosts. Three tick collections (two from Argentina and a third from the USA) house a total of 574 A. auricularium (307 males, 162 females, 73 nymphs and 32 larvae) and 179 A. pseudoconcolor (96 males, 74 females, 4 nymphs and 5 larvae). Apart from an adult A. pseudoconcolor found on a bird, Nothura maculosa Temminck, 1815, all ticks were found on mammals. The great majority of specimens of both ticks species were removed from the family Dasypodidae Gray, 1821 (84.9% and 93.8% of A. auricularium and A. pseudoconcolor, respectively). Amblyomma auricularium has also been found on wild hosts of the families Myrmecophagidae and occasionally Didelphidae, Caviidae, Chinchillidae, Hydrochaeridae, Muridae, Canidae, Mustelidae, Procyonidae and domestic animals (cattle, dogs, horses), while A. pseudoconcolor has also been found occasionally on wild hosts of the family Didelphidae and on domestic animals (cattle, dogs). Amblyomma pseudoconcolor appears to be restricted to the Neotropical region, covering northern Argentina and the eastern region of South America from Uruguay to Surinam, including south-eastern Paraguay, eastern Brazil and French Guiana. Amblyomma auricularium is distributed from northern Patagonia in Argentina throughout the Neotropics into the Nearctic region up to the southern USA (Texas, Florida), with collection localities also in Belize, Bolivia, Brazil, Colombia, Costa Rica, French Guiana, Honduras, Mexico, Nicaragua, Panama, Paraguay, Trinidad & Tobago, Uruguay and Venezuela. It is not known whether A. auricularium is an established resident of the USA.

Burnout syndrome is related to cultural and individual factors. The aim of this study was to compare the frequency of burnout and the scores for its three components with the perceptions and the demographic and professional characteristics of the workers. Burnout syndrome was studied in 11,530 Hispanic Americans and Spanish healthcare professionals (51% male, mean age 41.7 years). The Maslach Burnout Inventory and a previously drawn up questionnaire were administered online from the Intramed website from December 2006 to September 2007. Associations were tested using multiple logistic regression. The frequency of burnout in professionals resident in Spain was 14.9%, in Argentina 14.4%, and in Uruguay 7.9% whereas professionals in Mexico, Ecuador, Peru, Columbia, Uruguay, Guatemala and El Salvador presented frequencies of burnout of between 2.5% and 5.9%. By professions, doctors had a prevalence of burnout of 12.1%, nurses 7.2%, and dentists, psychologists and nutritionists of <6%. Amongst doctors, burnout predominated amongst doctors working in emergency departments (17%) and internal medicine departments (15.5%) whereas anaesthetists and dermatologists had the lowest prevalence (5% and 5.3%, respectively). Older age (OR=0.96), having children (OR=0.93), the perception of feeling valued (OR=0.53), optimism (OR=0.80), job satisfaction (OR=0.80), and satisfaction with salary (OR=0.91) are variables which protect against burnout. The expression of burnout varies among nations and professions. Age (older age), having children, the perception of feeling valued, optimism, job satisfaction and satisfaction with salary are protective variables of burnout.

To systematically review publications on Echinococcus granulosus sensu lato species/genotypes reported in domestic intermediate and definitive hosts in South America and in human cases worldwide, taking into account those articles where DNA sequencing was performed; and to analyse the density of each type of livestock that can act as intermediate host, and features of medical importance such as cyst organ location. Literature search in numerous databases. We included only articles where samples were genotyped by sequencing since to date it is the most accurate method to unambiguously identify all E. granulosus s. l. genotypes. Also, we report new E. granulosus s. l. samples from Argentina and Uruguay analysed by sequencing of cox1 gene. In South America, five countries have cystic echinococcosis cases for which sequencing data are available: Argentina, Brazil, Chile, Peru and Uruguay, adding up 1534 cases. E. granulosus s. s. (G1) accounts for most of the global burden of human and livestock cases. Also, E. canadensis (G6) plays a significant role in human cystic echinococcosis. Likewise, worldwide analysis of human cases showed that 72.9% are caused by E. granulosus s. s. (G1) and 12.2% and 9.6% by E. canadensis G6 and G7, respectively. E. granulosus s. s. (G1) accounts for most of the global burden followed by E. canadensis (G6 and G7) in South America and worldwide. This information should be taken into account to suit local cystic echinococcosis control and prevention programmes according to each molecular epidemiological situation. © 2015 John Wiley & Sons Ltd.

The World Health Organization advocates for faculties of medicine to orient health professional education toward the needs of the populations graduates are to serve and to include a greater emphasis on primary health care. It was in this framework that in 2007, the Faculty of Medicine and Health Sciences at the Université de Sherbrooke (FMHS-UdeS) in Canada and the Facultad de Medicina de la Universidad de la Republica (FMUdelaR) in Montevideo, Uruguay developed a comprehensive collaboration to sustain the development of family medicine in both universities through education, practice and research. ACTIVITIES AND OUTCOMES: In addition to information sharing through email and teleconferencing, this five year collaboration has included 28 bilateral visits by the two institutions' teachers and leaders. During these visits, Uruguayan members participated in workshops and benefited from exchanges during educational and clinical activities. Interactions led to the improvement of their skills as teachers of family medicine with an emphasis on clinical teaching, supervision, feedback to learners in clinical evaluations, use of various educational methods, use of standardized patients for teaching and evaluation, and research. FMHS-UdeS members learned about the community aspects of family medicine in Uruguay and reflected on how these could be implemented to the benefit of Canadians. The international collaboration forged between the FMHS-UdeS and the FMUdelaR represents a socially responsible endeavor that has been highly rewarding for all involved. It represents a significant learning opportunity for each group aiming to better prepare physicians to serve as primary health care providers in their communities.

To describe the trends in antibiotic utilization in eight Latin American countries between 1997-2007 We analyzed retail sales data of oral and injectable antibiotics (World Health Organization (WHO) Anatomic Therapeutic Chemical (ATC) code J01) between 1997 and 2007 for Argentina, Brazil, Chile, Colombia, Mexico, Peru, Uruguay, and Venezuela. Antibiotics were aggregated and utilization was calculated for all antibiotics (J01); for macrolides, lincosamindes, and streptogramins (J01 F); and for quinolones (J01 M). The kilogram sales of each antibiotic were converted into defined daily dose per 1 000 inhabitants per day (DID) according to the WHO ATC classification system. We calculated the absolute change in DID and relative change expressed in percent of DID variation, using 1997 as a reference Total antibiotic utilization has increased in Peru, Venezuela, Uruguay, and Brazil, with the largest relative increases observed in Peru (5.58 DID, +70.6%) and Venezuela (4.81 DID, +43.0%). For Mexico (-2.43 DID; -15.5%) and Colombia (-4.10; -33.7%), utilization decreased. Argentina and Chile showed major reductions in antibiotic utilization during the middle of this period. In all countries, quinolone use increased, particularly sharply in Venezuela (1.86 DID, +282%). The increase in macrolide, lincosaminde, and streptogramin use was greatest in Peru (0.76 DID, +82.1%), followed by Brazil, Argentina, and Chile Analyzing antibiotic utilization in Latin America presents a series of challenges. Creating policy-relevant evidence based on antimicrobial consumption patterns is needed in order to foster policies aimed at improving appropriate use of antibiotics in the region.

Wilson's Phalaropes, Steganopus tricolor, migrate in late summer from the prairie regions of North America to their wintering grounds in the highlands of Peru and the inland and coastal waters of Chile, Bolivia, Paraguay, Uruguay, and Argentina (Holmes 1939, Meyer de Schauensee 1970). Reports on these birds from their wintering habitat are few. This paper describes numbers, feeding behavior, and molt of Wilson's Phalaropes wintering in a freshwater marsh in central Argentina. Fieldwork in Argentina was conducted by the senior author. The junior author analyzed molt patterns of birds collected there and added data he collected in North Dakota in 1968 and 1969.

over the past three decades there has been a social movement in Latin American countries (LAC) to support humanised, physiologic birth. Rates of caesarean section overall in Latin America are approximately 35%, increasing up to 85% in some cases. There are many factors related to poor outcomes with regard to maternal and newborn/infant health in LAC countries. Maternal and perinatal outcome data within and between countries is scarce and inaccurate. The aims of this study were to: i) describe selected obstetric and neonatal outcomes of women who received midwifery care, ii) identify the level of maternal well-being after experiencing midwifery care in 6 Latin America countries. this was a cross sectional and descriptive study, conducted in selected maternity units in Argentina, Brazil, Chile, the Dominican Republic, Peru, and Uruguay. Quantitative methods were used to measure midwifery processes of care and maternal perceptions of well-being in labour and childbirth through a validated survey of maternal well-being and an adapted version of the American College of Nurse-Midwives (ACNM) standardized antepartum and intrapartum data set. Maternity units from 6 Latin American countries. the final sample was a convenience sample, and the total participants for all sites in the six countries was 3009 low risk women. for the countries reporting, overall, 82% of these low risk women had spontaneous vaginal deliveries. The rate of caesarean section was 16%; the Dominican Republic had the highest rate of Caesarean sections (30%) and Peru had the lowest rate (4%). The use of oxytocin in labour was widely variable, although overall there was a high proportion of women whose labour was augmented or induced. Ambulation was common, with the lowest proportion (48%) of women ambulating in labour in Chile, Uruguay (50%), Peru (65%), Brazil (85%). The presence of continuous support was highest in Uruguay (93%), Chile (75%) and Argentina (55%), and Peru had the lowest (22

We analyzed plastic ingestion by Kelp Gull (Larus dominicanus) from 806 pellets collected between 2011 and 2013. Employing a Raman spectroscopy, we characterized those polymers used to produce the plastics ingested. Debris was recorded in 143 pellets (%FO=17.7%, n=202, 92.58g). Plastic was found in 119 pellets (%FO=83%) and non-plastic occurred in 56 pellets (%FO=39%). The most important debris category was plastic film with 55.3% (n=79). Plastic bags were observed in 19 pellets (%FO=2.4%, weight=25.02g). Glass was the second most important component (%FO=18.9%) followed by plastic fragments (%FO=17.8%). Plastic debris represented the 65.3% of the debris fragments (n=132, weight=58.84g), and was composed by polyethylene (52%), polypropylene (26%), polyamide (12%), polystyrene (6%), polyvinyl chloride (2%), and polyethylene terephthalate (2%). How plastics were obtained by gulls and the effects on individuals are discussed, as well as environmental considerations about plastic pollution on coastal environments.

Mandrini, C. H.; Démoulin, P.; van Driel-Gesztelyi, L.; Schmieder, B.; Bagalá, L. G.; Rovira, M. G.

Se han obtenido observaciones desde Tierra (Hα y magnetogramas) coordinadas con el Soft X-ray Telescope (SXT), a bordo del satélite japonés Yohkoh, de una región activa bipolar en decaimiento. Estos datos constituyen la base para el estudio de un punto brillante en rayos X (PBX) y de la actividad relacionada con el mismo en distintas capas de la atmósfera solar. Las observaciones muestran que el PBX está relacionado con la aparición de un bipolo menor (~ 1020 Mx) y que su abrillantamiento continuo, así como sus aumentos de brillo esporádicos (``fulguraciones"), son el resultado de la reconexión entre el pequeño arco emergente (visto en Hα como un sistema de filamentos arqueados, SFA) y arcos mayores asociados al campo facular preexistente. Se ha extrapolado el campo magnético observado en la aproximación libre de fuerzas lineal y se ha seguido su evolución a lo largo de la vida del PBX. Se ha calculado la posición de las cuasiseparatrices (CSs) a partir del campo modelado. Las líneas de campo extrapoladas, cuyas bases fotosféricas se encuentran a ambos lados de las CSs, están de acuerdo con las estructuras cromosféricas y coronales observadas. Se ha calculado el espesor de la CD ubicada a lo largo de la polaridad negativa emergente, encontrándose que su variación está de acuerdo con la evolución de la intensidad del PBX; la CS es muy delgada durante la vida del PBX (~ 100 m), mientras que su espesor aumenta considerablemente (>= 10^4 m) cuando el PBX desaparece de las imágenes del SXT. Estos resultados señalan que el abrillantamiento y las ``fulguraciones" de este PBX se deben al proceso de reconexión en 3D que tiene lugar en las CSs.

Abstract The horn fly, Haematobia irritans is an obligate haematophagous cosmopolitan insect pest. The first reports of attacks on livestock by Haematobia irritans in Argentina and Uruguay occurred in 1991, and since 1993 it is considered an economically important pest. Knowledge on the genetic characteristics of the horn fly increases our understanding of the phenotypes resistant to insecticides that repeatedly develop in these insects. The karyotype of Haematobia irritans, as previously described using flies from an inbred colony, shows a chromosome complement of 2n=10 without heterochromosomes (sex chromosomes). In this study, we analyze for the first time the chromosome structure and variation of four wild populations of Haematobia irritans recently established in the Southern Cone of South America, collected in Argentina and Uruguay. In these wild type populations, we confirmed and characterized the previously published “standard” karyotype of 2n=10 without sex chromosomes; however, surprisingly a supernumerary element, called B-chromosome, was found in about half of mitotic preparations. The existence of statistically significant karyotypic diversity was demonstrated through the application of orcein staining, C-banding and H-banding. This study represents the first discovery and characterization of horn fly karyotypes with 2n=11 (2n=10+B). All spermatocytes analyzed showed 5 chromosome bivalents, and therefore, 2n=10 without an extra chromosome. Study of mitotic divisions showed that some chromosomal rearrangements affecting karyotype structure are maintained as polymorphisms, and multiple correspondence analyses demonstrated that genetic variation was not associated with geographic distribution. Because it was never observed during male meiosis, we hypothesize that B-chromosome is preferentially transmitted by females and that it might be related to sex determination. PMID:25893073

Differential pricing, based on countries' purchasing power, is recommended by the World Health Organization to secure affordable medicines. However, in developing countries innovative drugs often have similar or even higher prices than in high-income countries. We evaluated the potential implications of trastuzumab global pricing policies in terms of cost-effectiveness (CE), coverage, and accessibility for patients with breast cancer in Latin America (LA). A Markov model was designed to estimate life-years (LYs), quality-adjusted life-years (QALYs), and costs from a healthcare perspective. To better fit local cancer prognosis, a base case scenario using transition probabilities from clinical trials was complemented with two alternative scenarios with transition probabilities adjusted to reflect breast cancer epidemiology in each country. Incremental discounted benefits ranged from 0.87 to 1.00 LY and 0.51 to 0.60 QALY and incremental CE ratios from USD 42,104 to USD 110,283 per QALY (2012 U.S. dollars), equivalent to 3.6 gross domestic product per capita (GDPPC) per QALY in Uruguay and to 35.5 GDPPC in Bolivia. Probabilistic sensitivity analysis showed 0 percent probability that trastuzumab is CE if the willingness-to-pay threshold is one GDPPC per QALY, and remained so at three GDPPC threshold except for Chile and Uruguay (4.3 percent and 26.6 percent, respectively). Trastuzumab price would need to decrease between 69.6 percent to 94.9 percent to became CE in LA. Although CE in other settings, trastuzumab was not CE in LA. The use of health technology assessment to prioritize resource allocation and support price negotiations is critical to making innovative drugs available and affordable in developing countries.

Central and South America comprise one of the areas characterized by high incidence rates for head and neck cancer. We describe the geographical and temporal trends in incidence and mortality of head and neck cancers in the Central and South American region in order to identify opportunities for intervention on the major identified risk factors: tobacco control, alcohol use and viral infections. We obtained regional- and national-level incidence data from 48 population-based cancer registries in 13 countries and cancer deaths from the WHO mortality database for 18 countries. Age-standardized incidence (ASR) and mortality (ASMR) rates per 100,000 person-years were estimated. Brazil had the highest incidence rates for oral and pharyngeal cancer in the region for both sexes, followed by Cuba, Uruguay and Argentina. Cuba had the highest incidence and mortality rates of laryngeal cancer in the region for males and females. Overall, males had rates about four times higher than those in females. Most countries in the region have implemented WHO recommendations for both tobacco and alcohol public policy control. Head and neck squamous-cell cancer (HNSCC) incidence and mortality rates in the Central and South America region vary considerably across countries, with Brazil, Cuba, French Guyana, Uruguay and Argentina experiencing the highest rates in the region. Males carry most of the HNSCC burden. Improvement and implementation of comprehensive tobacco and alcohol control policies as well as the monitoring of these factors are fundamental to prevention of head and neck cancers in the region.

2018-05-22

Hepatitis E virus (HEV) is one of the most frequent causes of acute viral hepatitis of enteric transmission worldwide. In South America the overall epidemiology has been little studied, and the burden of the disease remains largely unknown. A research of all scientific articles about HEV circulation in South America until November 2017 was carried out. Human seroprevalences of HEV varied according to the studied population: blood donors presented prevalence rates ranging from 1.8 to 9.8%, while reports from HIV-infected individuals, transplant recipients and patients on hemodialysis showed higher prevalence rates. Only two cases of chronic hepatitis in solid-organ transplant patients from Argentina and Brazil have been described. Detection of HEV in the swine population is widely prevalent in the region. Anti-HEV antibodies have also been detected in other animal species; among them, antibody detection was recently documented in wild boars from Uruguay. Although scarce, studies focused on environmental and food HEV detection have shown viral presence in these kind of samples, highlighting possible transmission sources of HEV in the continent. HEV genotype 3 was the most frequently detected in the region, with HEV genotype 1 detected only in Venezuela and Uruguay. HEV is widely distributed throughout South America, producing sporadic cases of acute hepatitis, but as a possible agent of chronic hepatitis. Finding the virus in humans, animals, environmental samples and food, show that it can be transmitted through many sources, alerting local governments and health systems to improve diagnosis and for the implementation of preventive measures.

Neosporosis in South America.

PubMed

Moore, D P

2005-01-20

This work gathers reports about Neospora-infections in South America. Neospora-infections have been reported from Argentina, Brazil, Chile, Paraguay, Peru and Uruguay. Evidence of exposure to N. caninum was mentioned in cattle, goats, sheep, dogs, cats, water buffaloes, alpacas, llamas, South American opossums, wolves and other wild canids. No antibodies were found in horses. Interesting epidemiological and pathological data were described. Two isolations were performed from dogs, one from cattle, and recently five from water buffaloes. Since the cattle industry is important in South America and reproductive losses caused by Neospora-infection have been identified, more investigations are needed in order to understand its epidemiology and control the disease.

In South America, the invasive feral pig (Sus scrofa Linnaeus) has become established in Argentina, Uruguay, Paraguay and in a wide range within Brazil, along the southern half of the Atlantic Forest, in the cerrado (savanna) and in the Pantanal wetland. The geographical ranges of the two most common South American native peccary (Tayassu pecari Link and Pecari tajacu Linnaeus) overlap almost entirely, and the feral pig now co-occurs with them in several areas. Because feral pig, white-lipped and collared peccary are considered ecological equivalents, there has been much speculation about possible competitive interactions among them (Desbiez et al. 2009, Sicuro & Oliveira 2002).

Chronic bee paralysis virus (CBPV) causes a disease characterized by trembling, flightless, and crawling bees, while Acute bee paralysis virus (ABPV) is commonly detected in apparently healthy colonies, usually associated to Varroa destructor. Both viruses had been detected in most regions of the world, except in South America. In this work, we detected CBPV and ABPV in samples of Uruguayan honeybees by RT-PCR. The detection of both viruses in different provinces and the fact that most of the analyzed samples were infected, suggest that, they are widely spread in the region. This is the first record of the presence of CBPV and ABPV in Uruguay and South America.

Patterns of social association in the franciscana, Pontoporia blainvillei

Little is known from living animals about the social patterns of the franciscana, Pontoporia blainvillei, a small dolphin inhabiting a narrow strip of coastal waters off Argentina, Uruguay, and Brazil. These dolphins tend to be found in small groups, typically composed of two or three individuals (Bordino et al. 1999). Throughout much of the species' range, franciscanas encounter artisanal gill nets (Praderi 1989, Corcuera et al. 1994, Bertozzi and Zerbini 2002, Bordino et al. 2002, Secchi et al. 2003). Entanglement in these nets results in the deaths of thousands of individuals each year, at levels that are likely unsustainable (Bordino and Albareda 2004, Cappozzo et al. 2007).

Acca sellowiana (O. Berg) Burret sin. Feijoa sellowiana (Myrtaceae) is a semiwoody fruit species native to South Brazil, Uruguay, and Argentina; edible fruits are tasty. The naturally occurring populations in Santa Catarina State show high variability in fruit size, color, and other features. A breeding program launched in 1990 resulted in the release of four Brazilian commercial varieties. The conventional clonal propagation methods of this species, such as cutting and grafting, have shown low efficiency. Therefore, tissue culture techniques were developed for mass propagation. This chapter describes several protocols based on organogenesis and somatic embryogenesis. Additional techniques including synthetic seed technology and temporary immersion system are also described.

Sustainable Innovation Strategies in Education: OLPC Case Studies in Ethiopia and Uruguay

Mangiatordi, Andrea; Pischetola, Magda

In the Knowledge Society great importance is given to sharing knowledge and information. The ICTs not only provide a very efficient infrastructure for this task, they also have radically changed the way we interact and access information. This effect is even more consistent among the younger generations, who were born and raised in an era when network communications were already nearly as common as any other service. This also means they met another generation, the one of their parents and teachers who did not experience the same immersion in technology as they did. A sort of conflict arises from this encounter: children who have been exposed to such a wide range of possibilities are taught by adults who consolidated a method based on analogical instruments and who think using different patterns. It seems necessary, given this scenario, to spend a great deal of effort in integrating teachers' methodologies with ICTs in order to create a better environment for children's education. This paper reflects on two different experiences from One Laptop Per Child deployments. The project, which is the largest attempt in the world to promote one-to-one computing in primary schools, is particularly interesting for the role it is having in changing the student-teacher relationship. Giving a laptop to every child in a country does not seem to be enough to reform a school system: strong effort must be made to teach the teachers how to better use these new resources in order to improve the quality of their pupils' learning experience. This means that the whole process must be sustainable and participated. The two environments studied are Ethiopian primary school classes and Uruguayan schools for children with special needs: in both cases the role of technology is critical for sustainable innovation. In the first case, there is evidence that the teachers need to be taught how to use the ICTs to enhance the quality of their work, while in the second case they need to learn how to use assistive technology to make the classroom environment really inclusive. Both researches tend to highlight the important role of ICTs for social inclusion and suggest strategies to use one-to-one technologies for this purpose.

Nosema ceranae Winter Control: Study of the Effectiveness of Different Fumagillin Treatments and Consequences on the Strength of Honey Bee (Hymenoptera: Apidae) Colonies.

In Uruguay, colonies of honey bees moving to Eucalyptus grandis plantation in autumn habitually become infected with the microsporidian Nosema ceranae , a parasite that attacks the digestive system of bees. Beekeepers attributed to N. ceranae depopulation of the colonies that often occurs at the end of the blooming period, and many use the antibiotic fumagillin to reduce the level of infection. The aim of this study was to compare the effectiveness of four different fumagillin treatments and determine how this antibiotic affects the strength of the colonies during the winter season. The colonies treated with fumagillin in July showed less spore load at the end of applications, being the most effective the following treatments: the four applications sprayed over bees of 30 mg of fumagillin in 100 ml of sugar syrup 1:1, and four applications of 90 mg of fumagillin in 250 ml of sugar syrup 1:1 using a feeder. However, 2 month after the treatment applications, the colonies treated with fumagillin were the same size as the untreated colonies. In September, the colonies treated and not treated with fumagillin did not differ in colony strength (adult bee population and brood area) or spores abundance. Our study demonstrates that fumagillin treatment temporarily decreased the spore load of N. ceranae , but this was not reflected in either the size of the colonies or the probability of surviving the winter regardless of the dose or the administration strategy applied. Given the results obtained, we suggest to not perform the pharmacological treatment under the conditions described in the experiment. En Uruguay las colonias de abejas melíferas que se trasladan a las forestaciones de Eucalyptus grandis en otoño indefectiblemente se infectan con el microsporido Nosema ceranae , parásito que ataca el sistema digestivo de las abejas.

Resumen Objetivos: obtener estimaciones de indicadores de cobertura de las pensiones por jubilación o retiro para la población mexicana de 65 y más años, y evaluar el impacto que tienen los sistemas de pensiones en las transiciones al retiro de los adultos en edades medias y avanzadas en México. Para ello se utilizan datos microeconómicos provenientes de la Encuesta Nacional de Salud y Envejecimiento. Mediante análisis econométrico se identifican los factores sociodemográficos, económicos, laborales e institucionales que están asociados al acceso a una pensión de jubilación, o bien, a la dependencia de otras fuentes de ingresos. Se encontró que, en México, las transiciones al retiro del mercado de trabajo en las etapas avanzadas del ciclo de vida son limitadas debido a las características eminentemente contributivas de los esquemas de pensiones, los cuales favorecen a la población con trayectorias laborales formales y más estables asociadas a: características de género, oportunidades educativas y posibilidades de inserción en el mercado laboral.

Maté tea is a nonalcoholic infusion widely consumed in southern South America, and may increase risk of esophageal squamous cell carcinoma (ESCC) and other cancers due to polycyclic aromatic hydrocarbons (PAH) and/or thermal injury. We pooled two case-control studies: a 1988 to 2005 Uruguay study and a 1986 to 1992 multinational study in Argentina, Brazil, Paraguay, and Uruguay, including 1,400 cases and 3,229 controls. We computed ORs and fitted a linear excess OR (EOR) model for cumulative maté consumption in liters/day-year (LPDY). The adjusted OR for ESCC with 95% confidence interval (CI) by ever compared with never use of maté was 1.60 (1.2-2.2). ORs increased linearly with LPDY (test of nonlinearity; P = 0.69). The estimate of slope (EOR/LPDY) was 0.009 (0.005-0.014) and did not vary with daily intake, indicating maté intensity did not influence the strength of association. EOR/LPDY estimates for consumption at warm, hot, and very hot beverage temperatures were 0.004 (-0.002-0.013), 0.007 (0.003-0.013), and 0.016 (0.009-0.027), respectively, and differed significantly (P < 0.01). EOR/LPDY estimates were increased in younger (<65) individuals and never alcohol drinkers, but these evaluations were post hoc, and were homogeneous by sex. ORs for ESCC increased linearly with cumulative maté consumption and were unrelated to intensity, so greater daily consumption for shorter duration or lesser daily consumption for longer duration resulted in comparable ORs. The strength of association increased with higher maté temperatures. Increased understanding of cancer risks with maté consumption enhances the understanding of the public health consequences given its purported health benefits.

 Latin America has a substantial burden of influenza and rising Internet access and could benefit from real-time influenza epidemic prediction web tools such as Google Flu Trends (GFT) to assist in risk communication and resource allocation during epidemics. However, there has never been a published assessment of GFT's accuracy in most Latin American countries or in any low- to middle-income country. Our aim was to evaluate GFT in Argentina, Bolivia, Brazil, Chile, Mexico, Paraguay, Peru, and Uruguay.  Weekly influenza-test positive proportions for the eight countries were obtained from FluNet for the period January 2011-December 2014. Concurrent weekly Google-predicted influenza activity in the same countries was abstracted from GFT. Pearson correlation coefficients between observed and Google-predicted influenza activity trends were determined for each country. Permutation tests were used to examine background seasonal correlation between FluNet and GFT by country.  There were frequent GFT prediction errors, with correlation ranging from r = -0.53 to 0.91. GFT-predicted influenza activity best correlated with FluNet data in Mexico follow by Uruguay, Argentina, Chile, Brazil, Peru, Bolivia and Paraguay. Correlation was generally highest in the more temperate countries with more regular influenza seasonality and lowest in tropical regions. A substantial amount of autocorrelation was noted, suggestive that GFT is not fully specific for influenza virus activity.  We note substantial inaccuracies with GFT-predicted influenza activity compared with FluNet throughout Latin America, particularly among tropical countries with irregular influenza seasonality. Our findings offer valuable lessons for future Internet-based biosurveillance tools. © The Author 2016. Published by Oxford University Press for the Infectious Diseases Society of America.

Zambra, N; Gimeno, D; Blache, D; van Lier, E

2015-03-01

Temperament can be defined as the fearfulness and reactivity of an animal in response to humans and strange, novel or threatening environments. The productive performance of an animal is affected by its temperament, and selection of calm animals might improve their adaptation to the farming environment and handling, as well as improve productivity. The temperament was measured in lambs of two breeds of sheep in Uruguay. The effects of dam's age, type of birth, age of the lamb and contemporary group (CG; lambs belonging to the same year, flock, sex and rearing group) on the temperament of the lambs and the heritability of temperament were estimated with a Bayesian analysis using Gibbs sampling. Overall, 4962 Corriedale lambs and 2952 Merino lambs from 13 farms were tested. Temperament was measured using the isolation box test, isolating a lamb inside the box for 30 s, and recording the vibrations produced by its movements. The average temperament score (±s.e.m.) of the Corriedale lambs was 24.7 (±0.23) and that of the Merino was 36.8 (±0.45). Temperament was not associated with dam's age, type of birth or lamb's age. There were no relevant differences in the agitation score between lambs born in 2010 and 2011. The mean of the distribution of possible values of heritability (±s.d.) was 0.18 (±0.05) for the Corriedale and 0.31 (±0.06) for the Merino. The likelihood of heritability values to be greater than 0.15 exceeded 70% in the Corriedale and 90% in the Merino. The temperament of Merino and Corriedale sheep in Uruguay is moderately heritable. It is not related to dam's age, type of birth or age of the lambs; however, it is affected by some aspect of the CG.

Integrating evidence-based clinical practice guidelines on gastroesophageal reflux disease into medical practice is of prime importance in Latin America, given its high prevalence in this region. The aim of this project was to implement and assess an educational intervention on gastroesophageal reflux disease, aimed at primary care physicians in Latin America, with contents based on current clinical guidelines. The course included initial activities, whether face-to-face or through distance learning, and a 2-month period of Internet study and interaction. A pilot test was carried out in Uruguay, which was then repeated in 5 countries (Mexico, Colombia, Venezuela, Argentina and again in Uruguay). A global template was designed, which was then adapted to each of the countries: this was done with the participation of local institutions and leaders. Local credits were given for recertification. Participation was free. Of 3,110 physicians invited to participate, 1,143 (36.8%) started the course. Of these, 587 (51.4%) accessed at least half the contents of the course and 785 (68.7%) took part in the clinical discussions. A total of 338 (29.6%) completed all the requirements of the course and received a certificate. Among physicians who took both the pre- and post-intervention knowledge tests, scores improved from 60 to 80% (P<.001). Ninety-two percent of planned changes in clinical practice were related to the pedagogic aims of the course. In conclusion, a multifaceted, 2-phase continuing education course was successfully imparted in Latin America, with an overall design that was adapted to each country. Determination of specific needs and the participation of national experts were fundamental to the success of the course. Copyright © 2013 Elsevier España, S.L. and AEEH y AEG. All rights reserved.

The Latin American Society of Nephrology and Arterial Hypertension's Dialysis and Transplant Registry was chartered in 1991. It collects information on ESRD and its treatment in 20 countries of the region. The prevalence of patients on renal replacement therapy (RRT) increased from 129 pmp in 1992 to 447 pmp in 2004; in 2004, 56% of the patients were on hemodialysis, 23% on peritoneal dialysis, and 21% had a functioning kidney graft. The highest rates of prevalence were reported in Puerto Rico (1027 pmp), Chile (686 pmp), and Uruguay (683 pmp). Hemodialysis was widely used, except in El Salvador, Mexico, Guatemala, Nicaragua, and the Dominican Republic, where peritoneal dialysis predominated. Incidence rate increased from 27.8 pmp to 147 pmp in the same period of observation; the lowest rate was reported in Guatemala (11.4 pmp) and the highest in Puerto Rico (337.4 pmp). Diabetes mellitus was the leading cause of renal failure in incident patients; the highest rates were reported in Puerto Rico (62.2%) and Mexico (60%). Forty-four percent of the incident population were older than 65 years. Access to renal replacement therapy was universal in Argentina, Brazil, Chile, Cuba, Puerto Rico, Uruguay, and Venezuela, while was restricted in other countries. Main causes of death in dialysis were cardiovascular (44%) and infectious disease (26%). The rate of renal transplantation increased from 3.7 pmp in 1987 to 14.5 in 2004; fifty-three percent of the organs came from cadavers. Overall, donation rate was 5.9 pmp. In conclusion, the prevalence and incidence rates have increased over the years, and diabetes mellitus has emerged as the leading cause of kidney disease in the region. Although the rate of kidney transplantation has increased, the number remains insufficient to match the growing demand. The implementation of renal health programs in the region is urgently needed.

A Comparative Analysis of Prenatal Care and Fetal Growth in Eight South American Countries

Woodhouse, Cristina; Lopez Camelo, Jorge; Wehby, George L.

2014-01-01

There has been little work that comprehensively compared the relationship between prenatal care and infant health across multiple countries using similar data sources and analytical models. Such comparative analyses are useful for understanding the background of differences in infant health between populations. We evaluated the association between prenatal care visits and fetal growth measured by birth weight (BW) in grams or low birth weight (<2500 grams; LBW) adjusted for gestational age in eight South American countries using similarly collected data across countries and the same analytical models. OLS and logistic regressions were estimated adjusting for a large set of relevant infant, maternal, and household characteristics and birth year and hospital fixed effects. Birth data were acquired from 140 hospitals that are part of the Latin American Collaborative Study of Congenital Malformations (ECLAMC) network. The analytical sample included 56,014 live-born infants (∼69% of total sample) with complete data born without congenital anomalies in the years 1996–2011 in Brazil, Argentina, Chile, Venezuela, Ecuador, Colombia, Bolivia, and Uruguay. Prenatal care visits were significantly (at p<.05) and positively associated with BW and negatively associated with LBW for all countries. The OLS coefficients ranged from 9 grams per visit in Bolivia to 36 grams in Uruguay. The association with LBW was strongest for Chile (OR = 0.87 per visit) and lowest for Argentina and Venezuela (OR = 0.95). The association decreased in the recent decade compared to earlier years. Our findings suggest that estimates of association between prenatal care and fetal growth are population-specific and may not be generalizable to other populations. Furthermore, as one of the indicators for a country’s healthcare system for maternal and child health, prenatal care is a highly variable indicator between countries in South America. PMID:24625630

Burden of colorectal cancer in Central and South America.

Sierra, Monica S; Forman, David

2016-09-01

The colorectal cancer (CRC) burden is increasing in Central and South American due to an ongoing transition towards higher levels of human development. We describe the burden of CRC in the region and review the current status of disease control. We obtained regional- and national-level incidence data from 48 population-based cancer registries in 13 countries, as well as cancer deaths from the WHO mortality database for 18 countries. We estimated world population age-standardized incidence (ASR) and mortality (ASMR) rates per 100,000 person-years for 2003-2007 and the estimated annual percentage change for 1997-2008. The CRC rate in males was 1-2 times higher than that in females. In 2003-2007, the highest ASRs were seen in Uruguayan, Brazilian and Argentinean males (25.2-34.2) and Uruguayan and Brazilian females (21.5-24.7), while El Salvador had the lowest ASR in both sexes (males: 1.5, females: 1.3). ASMRs were<10 for both sexes, except in Uruguay, Cuba and Argentina (10.0-17.7 and 11.3-12.0). CRC incidence is increasing in Chilean males. Most countries have national screening guidelines. Uruguay and Argentina have implemented national screening programs. Geographic variation in CRC and sex gaps may be explained by differences in the prevalence of obesity, physical inactivity, diet, smoking and alcohol consumption, early detection, and cancer registration practices. Establishing optimal CRC screening programs is challenging due to lack of healthcare access and coverage, funding, regional differences and inadequate infrastructure, and may not be feasible. Given the current status of CRC in the region, data generated by population-based cancer registries is crucial for cancer control planning.

The La Plata River Basin is one of the largest international river basins in the world, with an area of about 3 million km2. It spreads across five countries (Argentina, Bolivia, Brazil, Paraguay and Uruguay), and its water resources are essential for their economic development. Together with reservoir development, extensive deforestation, intensive agriculture practices and large urban developments took place in the Paraná, Paraguay and Uruguay basins, affecting environmental conditions and raising important issues concerning water resources use and conservation. Therefore, the need to promote participatory and cooperative efforts among water resources stakeholders, as well as the systematic exchange of information and experiences on common regional problems among organizations and experts from throughout the basin who are devoted to water resources use and management, was reported by researchers and managers gathered at the First and Second International Workshops on Regional Approaches for Reservoir Development and Management in the La Plata River Basin (held in 1991 and 1994). As a concrete response to this need, the efforts of a number of organizations from various countries within the basin, with the support of international and national governmental organizations, resulted in the foundation of La Plata River Basin Environmental Research and Management Network (RIGA) in March 2001. This was within the framework of the Third International Workshop, which was precisely one of the short-term activities included in the RIGA Action Plan. During the preparatory processes for the RIGA Network, the presence of Japanese cooperation supporting the La Plata River Basin Workshops through a non-governmental international organization (ILEC) played an important role in stimulating such an organization-based joint approach in the basin. This outcome, although not originally planned, constituted a welcomed byproduct of its main specific interest in the region, which was the

Tobacco use has been identified as the single biggest cause of inequality in morbidity. The objective of this study is to examine the role of social determinants on current tobacco use in thirteen low-and-middle income countries. We used nationally representative data from the Global Adult Tobacco Survey (GATS) conducted during 2008-2010 in 13 low-and-middle income countries: Bangladesh, China, Egypt, India, Mexico, Philippines, Poland, Russian Federation, Thailand, Turkey, Ukraine, Uruguay, and Viet Nam. These surveys provided information on 209,027 respondent's aged 15 years and above and the country datasets were analyzed individually for estimating current tobacco use across various socio-demographic factors (gender, age, place of residence, education, wealth index, and knowledge on harmful effects of smoking). Multiple logistic regression analysis was used to predict the impact of these determinants on current tobacco use status. Current tobacco use was defined as current smoking or use of smokeless tobacco, either daily or occasionally. Former smokers were excluded from the analysis. Adjusted odds ratios for current tobacco use after controlling other cofactors, was significantly higher for males across all countries and for urban areas in eight of the 13 countries. For educational level, the trend was significant in Bangladesh, Egypt, India, Philippines and Thailand demonstrating decreasing prevalence of tobacco use with increasing levels of education. For wealth index, the trend of decreasing prevalence of tobacco use with increasing wealth was significant for Bangladesh, India, Philippines, Thailand, Turkey, Ukraine, Uruguay and Viet Nam. The trend of decreasing prevalence with increasing levels of knowledge on harmful effects of smoking was significant in China, India, Philippines, Poland, Russian Federation, Thailand, Ukraine and Viet Nam. These findings demonstrate a significant but varied role of social determinants on current tobacco use within and

We report five broad-nosed weevils of the tribe Naupactini, Naupactus leucoloma Boheman, Naupactus minor (Buchanan), Naupactus peregrinus (Buchanan), Naupactus tremolerasi Hustache and Pantomorus viridisquamosus (Boheman) (Coleoptera: Curculionidae) damaging soybean plants in the state of Rio Grande do Sul, Brazil. Some of these species are recorded for the first time in Brazil, and they all belong to species groups naturally distributed in the prairies of southern Brazil, Uruguay, Central Argentina and Paraguay. Three of them have been introduced, established and expanded in other countries outside South America. The five species in conjunction with other native species of Naupactini could cause severe damages to soybean crops if the root-feeding larvae attack young growing plants.

The discovery of an exceptionally well-preserved skull permits the description of the new South American fossil species of the rodent, Josephoartigasia monesi sp. nov. (family: Dinomyidae; Rodentia: Hystricognathi: Caviomorpha). This species with estimated body mass of nearly 1000 kg is the largest yet recorded. The skull sheds new light on the anatomy of the extinct giant rodents of the Dinomyidae, which are known mostly from isolated teeth and incomplete mandible remains. The fossil derives from San José Formation, Uruguay, usually assigned to the Pliocene–Pleistocene (4–2 Myr ago), and the proposed palaeoenvironment where this rodent lived was characterized as an estuarine or deltaic system with forest communities.

Small interfering RNAs (siRNAs) are now established as the preferred tool to inhibit gene function in mammalian cells yet trigger unintended gene silencing due to their inherent miRNA-like behavior. Such off-target effects are primarily mediated by the sequence-specific interaction between the siRNA seed regions (position 2–8 of either siRNA strand counting from the 5′-end) and complementary sequences in the 3′UTR of (off-) targets. It was previously shown that chemical modification of siRNAs can reduce off-targeting but only very few modifications have been tested leaving more to be identified. Here we developed a luciferase reporter-based assay suitable to monitor siRNA off-targeting in a high throughput manner using stable cell lines. We investigated the impact of chemically modifying single nucleotide positions within the siRNA seed on siRNA function and off-targeting using 10 different types of chemical modifications, three different target sequences and three siRNA concentrations. We found several differently modified siRNAs to exercise reduced off-targeting yet incorporation of the strongly destabilizing unlocked nucleic acid (UNA) modification into position 7 of the siRNA most potently reduced off-targeting for all tested sequences. Notably, such position-specific destabilization of siRNA–target interactions did not significantly reduce siRNA potency and is therefore well suited for future siRNA designs especially for applications in vivo where siRNA concentrations, expectedly, will be low.

Agreement on abortion unravels. Vatican criticized for tough stance at U.N. conference.

PubMed

1994-09-08

The International Conference on Population and Development, underway in Cairo, has been dominated by acrimonious debate on the issue of abortion. By the third day of the conference, agreement had been reached by 90% of the proposed Program of Action. Delegates appeared to have developed a compromise passage that urged governments to recognize illegal abortion as a major public health problem. However, hours after the compromise, delegations from Argentina, Ecuador, Guatemala, Honduras, Malta, Slovakia, Uruguay, and Guam--all of which have Roman Catholic majorities--withdrew their support, claiming that some phrases were pro-abortion. Many conference participants are concerned that the Vatican and its Muslim allies are forcing the issue of women's lives and health to become subordinated to a male-dominated political struggle.

Epidemic cholera in Latin America: spread and routes of transmission.

PubMed

Guthmann, J P

1995-12-01

In the most recent epidemic of cholera in Latin America, nearly a million cases were reported and almost 9000 people died between January 1991 and December 1993. The epidemic spread rapidly from country to country, affecting in three years all the countries of Latin America except Uruguay and the Caribbean. Case-control studies carried out in Peru showed a significant association between drinking water and risk of disease. Cholera was associated with the consumption of unwashed fruit and vegetables, with eating food from street vendors and with contaminated crabmeat transported in travellers' luggage. This article documents the spread of the epidemic and its routes of transmission and discusses whether the introduction of the epidemic to Peru and its subsequent spread throughout the continent could have been prevented.

The primary goal of Mohs micrographic surgery (MMS) is to completely excise a cancerous lesion and a wide range of reconstructive techniques of varying complexity are used to close the resulting wound. In this study, we performed a descriptive analysis of patients who underwent MMS, with a focus on wound closure methods. We conducted a bidirectional descriptive cohort analysis of all MMS procedures performed by a single surgeon between November 2013 and April 2016. Cosmetic outcomes were photographically assessed by a dermatologist after a minimum follow-up of 90 days. We analyzed 100 MMS procedures in 71 patients with a median age of 73 years. The tumors were basal cell carcinoma (70%), squamous cell carcinoma (29%), and dermatofibrosarcoma protuberans (1%); 75% were located on the head and neck. The reconstructive techniques used were flap closure (48%), simple closure (36%), closure by second intention (11%), and other (5%). Cosmetic outcomes were assessed for 70 procedures (47 patients) and the results were rated as excellent in 20% of cases, very good in 40%, good in 20%, moderate in 17%, and bad/very bad in 2.9%. No significant associations were observed between cosmetic outcome and sex, Fitzpatrick skin type, hypertension, diabetes mellitus, or smoking. Worse outcomes, however, were significantly associated with larger tumor areas and defects, location on the trunk, and flap and second-intention closure. Although there was a tendency to use simple wound closure for lesions located on the trunk and surgical defects of under 4.4cm 2 , the choice of reconstructive technique should be determined by individual circumstances with contemplation of clinical and tumor-related factors and the preference and experience of the surgeon.

We describe the first outbreak of Klebsiella pneumoniae carbapenemase-producing K. pneumoniae (KPC-KP), the infection control measures adopted and the shift in resistance patterns of isolates during antibiotic treatment. The ST258 KPC-KP strain exhibited a multiresistant antibiotic phenotype including co-resistance to gentamycin, colistin and tigecycline intermediate susceptibility. Isolates before and after treatment had different behaviour concerning their antibiotic susceptibility and the population analysis profile study. A progressive increase in the aminoglycosides (acquiring amicacin resistance) and β-lactam MICs, and a decreased susceptibility to fosfomycin was observed throughout the administration of combined antimicrobial regimens including meropenem. A high meropenem resistance KPC-KP homogeneous population (MIC 256 Jg/mL), could arise from the meropenem heterogeneous low-level resistance KPC-KP population (MIC 8 Jg/mL), by the selective pressure of the prolonged meropenem therapy. The kpc gene was inserted in a Tn4401 isoform a, and no transconjugants were detected. The core measures adopted were successful to prevent evolution towards resistance dissemination. PMID:25356345

The forest area submerged was greater than 280 km{sup 2} and resulted in large inputs of carbon, nitrogen and phosphorus to the reservoirs. After 46 years wood released 40, 34 and 71% of their original contents of carbon, nitrogen and phosphorus, respectively. During the same period the total amount of nutrients released by wood in comparison to leaves and litter is slightly less for nitrogen, almost double for phosphorus and more than three times for carbon.

We present a very simple concrete model to demonstrate the concept of phases of an illuminated body. The main objective of our model is to help the understanding of the Moon phases as viewed from the perspective of an observer on Earth. The material allows the visualization of two important effects: (1st) even though all the time half Moon is illuminated by the Sun, we see different fractions of the illuminated Moon surface, depending on our angle of sight; (2nd) the orientation of the convex part of the Moon in the crescent and waning phases on the sky also depends on our perspective from Earth. The use of a closed box allows one to see the contrast among the different phases with no need of a dark room. We also present a text on the Moon phases, emphasizing the dependence of the aspect of the bright part on the angle of sight. En este trabajo proponemos la construcción de material didáctico de bajo costo para demostración del concepto de fases de un cuerpo iluminado. El principal objetivo de nuestro material es facilitar la comprensión de las fases de la Luna desde la perspectiva de un observador en la Tierra. El material ayuda la visualización de dos efectos importantes: (1º) a pesar de tener siempre la mitad de la Luna (representada por una bolita de espuma plástica o de ping-pong), iluminada por el Sol ( representado por una fuente de luz natural o artificial), vemos diferentes fracciones de su superficie iluminada, dependiendo del ángulo por el cual la vemos; (2º) la orientación del borde convexo de la Luna en las fases Creciente y Menguante también depende de la perspectiva por la cual la miramos desde la Tierra.

The World Health Organization has estimated that by 2030, chronic obstructive pulmonary disease will be the third leading cause of death worldwide. Most knowledge of chronic obstructive pulmonary disease is based on studies performed in Europe or North America and little is known about the prevalence, patient characteristics and change in lung function over time in patients in developing countries, such as those of Latin America. This lack of knowledge is in sharp contrast to the high levels of tobacco consumption and exposure to biomass fuels exhibited in Latin America, both major risk factors for the development of chronic obstructive pulmonary disease. Studies have also demonstrated that most Latin American physicians frequently do not follow international chronic obstructive pulmonary disease diagnostic and treatment guidelines. The PRISA Study will expand the current knowledge regarding chronic obstructive pulmonary disease and risk factors in Argentina, Chile and Uruguay to inform policy makers and health professionals on the best policies and practices to address this condition. PRISA is an observational, prospective cohort study with at least four years of follow-up. In the first year, PRISA has employed a randomized three-staged stratified cluster sampling strategy to identify 6,000 subjects from Marcos Paz and Bariloche, Argentina, Temuco, Chile, and Canelones, Uruguay. Information, such as comorbidities, socioeconomic status and tobacco and biomass exposure, will be collected and spirometry, anthropometric measurements, blood sampling and electrocardiogram will be performed. In year four, subjects will have repeat measurements taken. There is no longitudinal data on chronic obstructive pulmonary disease incidence and risk factors in the southern cone of Latin America, therefore this population-based prospective cohort study will fill knowledge gaps in the prevalence and incidence of chronic obstructive pulmonary disease, patient characteristics and

BACKGROUND Primitive electronic waste (e-waste) recycling creates exposures to several hazardous substances including lead. In Uruguay, primitive recycling procedures are a significant source of lead exposure. OBJECTIVES The aim of this study was to examine lead exposure in blood lead levels (BLLs) in low-income children exposed to lead through burning cables. METHODS A sample of children and adolescents exposed to lead through burning cable activities were assessed at the Department of Toxicology in Montevideo, Uruguay, between 2010 and 2014. Soil lead levels of residences were taken shortly after their assessment. FINDINGS The final sample included 69 children and adolescents (mean age 7.89 years). More than 66% of participants had an additional source of lead exposure—manual gathering of metals—and <5% were exposed to lead through landfills or paint. Average BLLs at first consultation were 9.19 ug/dL and lower at the second measurement (5.86 μg/dL). Data from soil lead levels ranged from 650 to 19,000 mg of lead/kg of soil. The interventions conducted after the assessment included family education in the clinic and at home, indoor and outdoor remediation. We found a decrease in BLLs of 6.96 μg/dL. Older children had lower BLLs (r = −0.24; P =0.05). Statistical analyses also showed that children living in areas with higher soil lead levels had significantly higher BLLs (r = 0.50; P < 0.01). Additionally, we found greater BLLs from burning cable activities when children had been exposed to lead-based paint (r = 0.23; P < 0.1). CONCLUSION Among children exposed to e-waste recycling, the most common additional source of lead exposure was the manual gathering of metals. The average BLL among children and adolescents in this study is higher than the BLLs currently suggested in medical intervention. Future research should focus on exploring effective interventions to reduce lead exposure among this vulnerable group. PMID:27325077
