    The population aging in Brazil and in the world is a reason for an epidemic inquietude. So, the violence against senior people has been considered a problem of public health. This study takes as context the health need of seniors that suffer of violence, aiming to evaluate in a constructive way the Disque Idoso Project in Sobral (Ceará, Brazil). We used Furtado's Constructivist Method of Evaluation, which provides practices of participative evaluation. Trying to reach such perspective, we are guided by paths of the integrative approach (inter, multi and transdisciplinary) and intersectoral. We accomplished the focal groups with representatives of the sections of health, social assistance, justice and senior, the benefited by the project as well as others that contribute to its development. When interacting with the professionals that act in the project headquarters we understood that there is a fear in publishing their work, because there is not structure to enlarge the attendance. The group believes that the efficiency of its actions is limited due to the lack of transport and other professionals. For the professionals of the support social networks, the project should look for intersectoral performance, once it intends to reach a complete attendance. For the seniors, the project is quite valid and needs to be consolidated in the district.

    The article describes assessments and measurements performed in the Brazilian Longitudinal Study for Adult Health (ELSA-Brasil). Some assessments including anthropometric assessment, casual blood pressure measurement, and ankle-brachial index have an established clinical application while others including pulse wave velocity, heart rate variability, and carotid intima-media thickness have no established application and do not have reference values for healthy Brazilian population but may be important predictors of cardiovascular outcomes. Blood pressure measurement following postural change maneuver was included in the ELSA-Brasil because it has not been much tested in epidemiological studies. Innovative approaches were developed for assessing the ankle-brachial index using an automatic device instead of the mercury column to measure blood pressure and for assessing the anterior-posterior diameter of the right lobe of the liver by ultrasound for quantitative assessment of nonalcoholic fatty liver disease. All ELSA-Brasil subjects were younger (35 years or more) than those included in other cohorts studying subclinical atherosclerosis. The inclusion of younger individuals and a variety of assessments make the ELSA-Brasil a relevant epidemiology study nationwide and worldwide.

  3. Improving weather modeling in South America through IDD-Brasil

    The IDD-Brasil constitutes of an international collaboration among Universidade Federal do Rio de Janeiro (LPM/UFRJ), Centro de Previsão de Tempo e Estudos Climáticos (CPTEC/INPE) and the Unidata Program Center (Unidata/UCAR), which connects several universities and research centers across the Americas in a network to share real-time hydro meteorological data. Using this network as a new path to deliver and acquire observational data, IDD-Brazil participants are capable of receiving observational data from GTS (Global Telecommunication System), locally ingested data from several automatic weather stations networks (mesonets) from INPE, the entire array of METAR and SYNOP observations, and several model outputs and satellite imagery. During recent years Numerical Models have been used constantly, especially in mesoscale research, but the lack of a dense observational network in South America leads to several constraints during the data assimilation and model validation. Since the IDD-Brasil offers an improved and simple method to have new datasets readily accessible, it has been used continuously as a new manner to distribute surface observations that are not currently available in GTS, such as several mesonets in Brazil that account for an increase in data density. Through the usage of data ingested in IDD-Brasil as guess fields it is possible to study how the assimilation in several global models frequently used as initial conditions for mesoscale simulations can be affected, since in certain areas in Brazil the density of data nearly doubles if compared to GTS. Therefore it is also possible to better validate the results generated in mesoscale simulations, in view of the fact that the network has an improved spatial distribution. It is expected that the increase of locally held numerical model output from South American institutions in IDD- Brasil leads to an increased awareness of the need to constantly validate these results with observational data, thus

    Chronic diseases are a global problem, yet information on their determinants is generally scant in low- and middle-income countries. The Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) aims to contribute relevant information regarding the development and progression of clinical and subclinical chronic diseases, particularly cardiovascular diseases and diabetes, in one such setting. At Visit 1, we enrolled 15 105 civil servants from predefined universities or research institutes. Baseline assessment (2008–10) included detailed interviews and measurements to assess social and biological determinants of health, as well as various clinical and subclinical conditions related to diabetes, cardiovascular diseases and mental health. A second visit of interviews and examinations is under way (2012–14) to enrich the assessment of cohort exposures and to detect initial incident events. Annual surveillance has been conducted since 2009 for the ascertainment of incident events. Biological samples (sera, plasma, urine and DNA) obtained at both visits have been placed in long-term storage. Baseline data are available for analyses, and collaboration via specific research proposals directed to study investigators is welcome. PMID:24585730

    Brazililan energy policy during the last decade has focused on the replacement of imported petroleum with domestic energy sources, combined with efforts at conservation. The substitution results, however, have been more spectacular by far. The strategy of replacement is based on two elements. first, to increase domestic petroleum exploration and production. Second, to promote non-petroleum fuels as alternatives to the industrial and transportation sectors, for the substitution of fuel oil and gasoline, respectively. A combination of the substitution strategy, the country's petroleum refining structure, and the composition of the substitution strategy, the country's petroleum refining structure, and the composition of demand, has resulted in large surpluses of both gasoline and fuel oil, while diesel has become the most used among petroleum products. The surpluses are not easily exportable because there is ample availability of fuel oil in the world market, and because the low octane number of the gasoline produced in Brasil is not compatible with the engines of cars elsewhere in the region and in the world. Furthermore, although gasoline might be upgraded, the question remains that prospects for the world market are not encouraging, and an export-based strategy does not seem justified in view of the growing surpluses. The objective of this analysis is to review the mechanisms of themajor petroleum-substitution programs currently in existence, identifying their past impact on the energy market and the possible consequences of changes in the goals and operating conditions of these programs, in the light of the new prospects for increased domestic oil production and self-sufficiency. 23 refs., 2 figs., 1 tab.

    During an earthquake and tsunami, the Earth's atmosphere and ionosphere hosts varieities of disturbances. We refer, this phenomena, as seismic weather, drawing anology from the space weather. In this work, we study the seismic weather over Brasil, associated with the September Chile eqarthquake/tsunami. We aim to simulate this seismic weather for which the seismogenic magnetic and airglow disturbances over Brasil are already reported. We employ the Seismic-Atmsopheric-Ionospheric coupling model (SAI) developed by us, to study this seismic weather. The Earth's surface displacement obtained from seismometer is consisdered as an input to the model which them trigger the Acoustic-Gravity waves (AGWs) in the atmosphere and subsequent magnetic and airglow disturbances in the atmosphere-ionosphere coupled system. The results provide better understanding of coupling arising from the Rayleigh wave forcing.

    Objetivos. Buscamos cuantificar la manera en que los efectos socioeconómicos, demográficos, geográficos y de atención de salud explican las disparidades raciales en las tasas de bajo peso al nacer y prematuridad en Brasil. Métodos. Utilizamos una muestra de 8 949 niños nacidos entre 1995 y el 2009 en 15 ciudades y 7 provincias de Brasil. Nos centramos en las disparidades en la prevalencia de bajo peso al nacer (< 2 500 g) y prematuridad (< 37 semanas de gestación) en recién nacidos de ascendencia solo africana o mezclada con otras ascendencias y de ascendencia solo europea. Usamos un modelo de descomposición para cuantificar la contribución de los factores conceptualmente pertinentes a esas disparidades. Resultados. El modelo permitió explicar entre 45% y 94% de las disparidades en cuanto al bajo peso al nacer y entre 64% y 94% de las disparidades en cuanto a la prematuridad entre los grupos de ascendencia africana y de ascendencia europea. Las diferencias en el uso de atención prenatal y en la ubicación geográfica fueron los factores más importantes, seguidos por las diferencias socioeconómicas. El modelo permitió explicar la mayoría de las disparidades en los recién nacidos de ascendencia africana mezclada y parte de las disparidades en los de ascendencia solo africana. Conclusiones. En las políticas públicas para mejorar la salud infantil se deben abordar las diferencias en cuanto a la atención prenatal y la ubicación geográfica a fin de reducir las disparidades en materia de salud entre los recién nacidos de ascendencia africana y los de ascendencia europea en Brasil.

  9. Avança Brasil: environmental and social consequences of Brazil's planned infrastructure in Amazonia.

    2002-12-01

    "Avança Brasil" (Forward Brazil) is a package of 338 projects throughout Brazil; the portion of the plan to be carried out in Brazil's Legal Amazon region totals US$43 billion over 8 years, US$20 billion of which would be for infrastructure causing environmental damage. Brazil's environmental impact assessment system is not yet capable of coping with the challenge presented by Avança Brasil. Generic problems with the licensing process include stimulation of a lobby in favor of construction before decisions are made on the advisability of the projects, the "dragging effect" of third parties, whereby economic activity is attracted to the infrastructure but escapes the environmental impact assessment system, a tendency for consulting firms to produce favorable reports, a bureaucratic emphasis on the existence of steps without regard to the content of what is said, and the inability to take account of the chain of events unleashed when a given project is undertaken. The environmental and social costs of forest loss are high; among them is loss of opportunities for sustainable use of the forest, including loss of environmental services such as biodiversity maintenance, water cycling, and carbon storage. The benefits of export infrastructure are meager, especially from the point of view of generating employment. Much of the transportation infrastructure is for soybeans, while the hydroelectric dams contribute to processing aluminum. The example of Avança Brasil makes clear the need to rethink how major development decisions are made and to reconsider a number of the plan's component projects. PMID:12402090

    The food consumption of 15,071 public employees was analyzed in six Brazilian cities participating in the baseline for Brazilian Longitudinal Study of Adult Health (ELSA-Brasil, 2008-2010) with the aim of identifying eating patterns and their relationship to socio-demographic variables. Multiple correspondence and cluster analysis were applied. Four patterns were identified, with their respective frequencies: "traditional" (48%); "fruits and vegetables" (25%); "pastry shop" (24%); and "diet/light" (5%) The "traditional" and "pastry shop" patterns were more frequent among men, younger individuals, and those with less schooling. "Fruits and vegetables" and "diet/light" were more frequent in women, older individuals, and those with more schooling. Our findings show the inclusion of new items in the "traditional" pattern and the appearance of the "low sugar/low fat" pattern among the eating habits of Brazilian workers, and signal socio-demographic and regional differences.

    This work analyzes the trajectory of the history course at the Faculdade Nacional de Filosofia of the Universidade do Brasil between 1939 and 1964/1965. Special emphasis is placed on the period between 1955 and 1965, when there was the separation of the history and geography courses, through to the onset of the reorganization of the schools and institutes of the university. The Faculdade Nacional de Filosofia was a benchmark for the other schools of philosophy in the country, as well as being a reference in the development of the history of education in Brazil. The approach adopted is geared to the field of the history of the historiography, with a focus on the study of the trajectories, institutions and relationship networks.

    The neotropical characid Salminus franciscanus is an economically valuable migratory fish whose populations have been drastically reduced in recent decades due to industrial and economic development in Brasil. To study its reproduction, a total of 283 adult specimens were captured in the Upper São Francisco River, downstream from the Três Marias dam, Minas Gerais, south-eastern Brasil, from August 2009 to July 2010. The gonadal maturity stages were determined from histological features of the gonads and gonadosomatic index (GSI). Gametogenesis was assessed by light and electron microscopy. For analysis of the oocyte's surface and fecundity, mature females were subjected to hormonal induction and oocyte stripping. Fish in resting (Stage 1) were common in all samplings, ripening/ripe and spawning (Stages 2 and 3) were predominant in October-November and December-January and post-spawning (Stage 4) occurred from December-January extending until April-May. The GSI followed the morphological changes of gonadal maturation, with a peak in October-November, when maximum GSI (7.08 in females and 3.46 in males) was achieved. From scanning electron microscopy, stripped oocytes showed a funnel-shaped micropyle and a simple oocyte surface arrangement, which is typical for non-adhesive eggs. Fecundity ranged from 160 to 440×10(3) oocytes per female and 129 to 175×10(3)oocytes/kg. The results of this study indicate that S. franciscanus reproduces in the Upper São Francisco River from October to January, exhibiting a total spawning pattern, non-adhesive eggs and high fecundity, providing support for aquaculture and conservation biology of this important neotropical characid fish.

    Background Echocardiography, though non-invasive and having relatively low-cost, presents issues of variability which can limit its use in epidemiological studies. Objective To evaluate left ventricular mass reproducibility when assessed at acquisition (online) compared to when assessed at a reading center after electronic transmission (offline) and also when assessed by different readers at the reading center. Methods Echocardiographers from the 6 ELSA-Brasil study investigation centers measured the left ventricular mass online during the acquisition from 124 studies before transmitting to the reading center, where studies were read according to the study protocol. Half of these studies were blindly read by a second reader in the reading center. Results From the 124 echocardiograms, 5 (4%) were considered not measurable. Among the remaining 119, 72 (61%) were women, mean age was 50.2 ± 7.0 years and 2 had structural myocardial abnormalities. Images were considered to be optimal/ good by the reading center for 110 (92.4%) cases. No significant difference existed between online and offline measurements (1,29 g, CI 95% −3.60-6.19), and the intraclass correlation coefficient between them was 0.79 (CI 95% 0.71-0.85). For images read by two readers, the intraclass correlation coefficient was 0.86 (CI 95% 0.78-0.91). Conclusion There were no significant drifts between online and offline left ventricular mass measurements, and reproducibility was similar to that described in previous studies. Central quantitative assessment of echocardiographic studies in reading centers, as performed in the ELSA-Brasil study, is feasible and useful in clinical and epidemiological studies performed in our setting.

    Multi-center epidemiological studies must ascertain that their measurements are accurate and reliable. For laboratory measurements, reliability can be assessed through investigation of reproducibility of measurements in the same individual. In this paper, we present results from the quality control analysis of the baseline laboratory measurements from the ELSA-Brasil study. The study enrolled 15,105 civil servants at 6 research centers in 3 regions of Brazil between 2008-2010, with multiple biochemical analytes being measured at a central laboratory. Quality control was ascertained through standard laboratory evaluation of intra- and inter-assay variability and test-retest analysis in a subset of randomly chosen participants. An additional sample of urine or blood was collected from these participants, and these samples were handled in the same manner as the original ones, locally and at the central laboratory. Reliability was assessed with the intraclass correlation coefficient (ICC), estimated through a random effects model. Coefficients of variation (CV) and Bland-Altman plots were additionally used to assess measurement variability. Laboratory intra and inter-assay CVs varied from 0.86% to 7.77%. From test-retest analyses, the ICCs were high for the majority of the analytes. Notably lower ICCs were observed for serum sodium (ICC=0.50; 95%CI=0.31-0.65) and serum potassium (ICC=0.73; 95%CI=0.60-0.83), due to the small biological range of these analytes. The CVs ranged from 1 to 14%. The Bland-Altman plots confirmed these results. The quality control analyses showed that the collection, processing and measurement protocols utilized in the ELSA-Brasil produced reliable biochemical measurements.

    The main objective of the study was identify the prevalence and factors associated with leisure time physical activity (LTPA) in adult participants of the Longitudinal Study of Adult Health (ELSA-Brasil). The LTPA was measured using the International Physical Activity Questionnaire (IPAQ), long version. A hierarchical ecological model was built with the possible factors associated with LTPA distributed across blocks. We estimated crude and adjusted odds ratios (ORs) and 95% confidence intervals (95% CIs) using logistic regression. In men, being more educated, having a high family income, living in environments with conditions and opportunities for PA, being retired and being overweight were positively associated, while current smoking, obesity and abdominal obesity were associated negatively with the LTPA. Among women, being over 60years old, being more educated, having a high family income, living in an environment with conditions and opportunities for PA practice and being retired were positively associated, while being overweight, obese and having abdominal obesity were associated negatively with the LTPA. The proposed ecological model explains the LTPA through the social, physical and personal environment and highlights gender differences in physical activity.

    The "Farmácia Popular do Brasil" Program (PFPB) aims to improve access to medicines, offering subsidized products. It is structured in an arrangement involving public and private sectors. The paper described the organization and expansion of the PFPB and examined the reference price (RP) of the medicines paid by the government, between 2004 and 2012. It is an exploratory study of quantitative and qualitative approach, developed from the literature review and analysis of public documents. Quantitative data were collected from the Ministry of Health and Electronic System of Citizens Information Services. The PFPB is organized in two delivery models: public owned facilities (Rede Própria) and accredited private retail pharmacies (Aqui Tem Farmácia Popular-ATFP). The ATFP has allowed its own expansion, from 2006. Antihypertensives, antidiabetics and antiasthmatics were exempt from copayment, since 2011. The expansion of the ATFP Program was significant, for facilities and covered municipalities, 750% and 528%, respectively. The RP was reduced by 33.6% on average (ranging from 23-52%) for medicines available since the beginning of the ATFP. The expansion was performed with the actions hitherto unprecedented, as copayment and accreditation of private retail pharmacies.

    The detection efficiency (DE) is the most important performance gauge of a lightning detection network (LDN). Moreover, the main motivation for evaluating the DE of a LDN is to separate the geographical variations of the CG lightning parameters from the variations regarding the network performance. A review of previous relative DE techniques and simple methods to correct the cloud-to-ground (CG) lightning flash density maps is presented. In addition, recent improvements in the flash DE model for the Brazilian lightning detection network (BrasilDAT) are discussed. The DE estimated values are based on the sensor individual DE probability functions, which are derived from a large amount of CG stroke data provided by the network considering different distances from the sensor and specific peak current ranges. The new approach provides better results when compared with the previous developments, since the calculation of the sensor DE probability functions neglects the lightning data provided by the minimum number of reporting sensors. Hence it is possible to minimize the unrealistic enhancement of the DE closer to the network boundaries ("border effect") without affecting significantly the performance inside the network. The main result is a more realistic correction of the CG flash density maps, particularly at the outermost network areas, leading to an improvement in the model sensitivity.

    Previous studies of the association between symptoms of anxiety or depression and coronary artery calcium (CAC) have produced heterogeneous results. Our aim was to investigate whether psychopathological symptoms were associated with CAC in a cross-sectional analysis of the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) baseline. We analyzed data from 4,279 ELSA-Brasil subjects (aged 35 to 74 years) from the São Paulo site without previous cardiovascular disease who underwent CAC score assessment at baseline. Prevalent CAC was defined as a CAC score >0. Anxiety and depressive symptoms were assessed using the Clinical Interview Schedule-Revised (CIS-R). We built binary logistic regression models to determine whether CIS-R scores, anxiety, or depression were associated with prevalent CAC. Prevalent CAC was found in 1,211 subjects (28.3%). After adjustment for age and gender, a direct association between CIS-R scores and prevalent CAC was revealed (odds ratio for 1-SD increase: 1.12; 95% confidence interval [CI] 1.04 to 1.22). This association persisted after multivariate adjustment (odds ratio for 1-SD increase 1.11; 95% CI 1.02 to 1.20). No independent associations were found for specific diagnoses of anxiety or depression and prevalent CAC. In post hoc models, a significant interaction term (p = 0.019) suggested a stronger association in older subjects. In conclusion, psychopathological symptoms were directly associated with coronary atherosclerosis in the ELSA-Brasil baseline in adjusted models, and this association seems to be stronger in older subjects.

    Using baseline data from ELSA-Brasil (N = 15,105), we investigated whether subjective social status, measured using three 10-rung "ladders," is associated with self-rated health and smoking, independently of objective indicators of social position and depression symptoms. Additionally, we explored whether the magnitude of these associations varies according to the reference group. Subjective social status was independently associated with poor self-rated health and weakly associated with former smoking. The references used for social comparison did not change these associations significantly. Subjective social status, education, and income represent distinct aspects of social inequities, and the impact of each of these indicators on health is different.

    Background Regular physical activity (PA) induces desirable changes in plasma levels of high- and low-density lipoproteins (HDL and LDL, respectively) and triglycerides (TG), important risk factors for cardiometabolic diseases. However, doubts whether intensity and duration have equivalent benefits remain. Objective To assess the association of PA intensity and duration with HDL, LDL and TG levels. Methods Cross-sectional study with 12,688 participants from the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) baseline, who were not on lipid-lowering medication. After adjustment for important covariates, multiple linear regression was used to assess the association of PA intensity and duration with HDL, LDL and TG (natural logarithm) levels. Results Both moderate and vigorous PA and PA practice ≥ 150 min/week were significantly associated with higher HDL and lower TG levels. Vigorous PA was associated with lower LDL only on univariate analysis. After adjustments, moderate and vigorous PA increased mean HDL level by 0.89 mg/dL and 1.71 mg/dL, respectively, and reduced TG geometric mean by 0.98 mg/dL and 0.93 mg/dL, respectively. PA practice ≥ 150 min/week increased mean HDL level by 1.05 mg/dL, and decreased TG geometric mean by 0.98 mg/dL. Conclusion Our findings reinforce the benefits of both PA parameters studied on HDL and TG levels, with a slight advantage for vigorous PA as compared to the recommendation based only on PA duration.

    The prevalence of the metabolic syndrome is rising worldwide. Its association with alcohol intake, a major lifestyle factor, is unclear, particularly with respect to the influence of drinking with as opposed to outside of meals. We investigated the associations of different aspects of alcohol consumption with the metabolic syndrome and its components. In cross-sectional analyses of 14,375 active or retired civil servants (aged 35–74 years) participating in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil), we fitted logistic regression models to investigate interactions between the quantity of alcohol, the timing of its consumption with respect to meals, and the predominant beverage type in the association of alcohol consumption with the metabolic syndrome. In analyses adjusted for age, sex, educational level, income, socioeconomic status, ethnicity, smoking, body mass index, and physical activity, light consumption of alcoholic beverages with meals was inversely associated with the metabolic syndrome (≤4 drinks/week: OR = 0.85, 95%CI 0.74–0.97; 4 to 7 drinks/week: OR = 0.75, 95%CI 0.61–0.92), compared to abstention/occasional drinking. On the other hand, greater consumption of alcohol consumed outside of meals was significantly associated with the metabolic syndrome (7 to 14 drinks/week: OR = 1.32, 95%CI 1.11–1.57; ≥14 drinks/week: OR = 1.60, 95%CI 1.29–1.98). Drinking predominantly wine, which occurred mostly with meals, was significantly related to a lower syndrome prevalence; drinking predominantly beer, most notably when outside of meals and in larger quantity, was frequently associated with a greater prevalence. In conclusion, the alcohol—metabolic syndrome association differs markedly depending on the relationship of intake to meals. Beverage preference—wine or beer—appears to underlie at least part of this difference. Notably, most alcohol was consumed in metabolically unfavorable type and timing. If further investigations

    2014-01-01

    Background The early exposure to poor social and nutritional conditions may influence cognitive function during adult age. However, the relative impact of these factors has not yet been established and they can vary during the course of life. Methods Analysis of data from 12,997 participants (35-64 years) of the baseline exams (2008-2010) of the Longitudinal Study of Adult Health (ELSA-Brasil), a cohort of Brazilian civil servants. Four cognitive tests were applied: learning, recall and word recognition; semantic and phonemic verbal fluency; trail-making test version B. The markers of early nutritional and social conditions were maternal educational level, birth weight, and length of trunk and leg. The presence of independent association between every early marker and the poor performance in each cognitive test was investigated by multiple logistic regression, after mutual adjustment and considering the effects of gender, age and participant’s schooling level. The cut off for poor performance was the worst age-specific percentile of the final score distribution for each test. Results After full adjustments, lower maternal education increased the chances of poor performance in all cognitive tests, with a dose-response gradient; low birth-weight was related to poor performance in the trail-making test B (OR = 1.63, 95% IC = 1.29-2.06); and greater trunk length decreased the chances of poor performance in the semantic and phonemic verbal fluency (OR = 0.96, 95% IC = 0.94-0.97) and in the trail-making test B (OR = 0.94, 95% IC = 0.92-0.95). Leg length was not associated with any of the tests examined. The associations found were not modified by the educational attainment of the participants. Conclusions Early exposure to adverse social and nutritional conditions appear detrimental to semantic memory, learning, concentration, executive control and language among adults, independent of adulthood educational achievement.

    The association of body image dissatisfaction and obesity with physical activity is likely to differ according to gender. To investigate this hypothesis, we conducted a cross-sectional study among the ELSA-Brasil cohort members aged 34–65 years (n = 13,286). The body image dissatisfaction was present even among normal weight individuals of both sexes and was associated with lesser chances of practicing moderate physical activity in women and intense physical activity in men. Men and women with central obesity were less prone to practice physical activity of high or moderate intensity. Overweight and obese men were more likely to report vigorous physical activity while obese women were less likely to report this level of physical activity. Body images as well as nutritional status are related to physical activity in both sexes, but the association with physical activity differs by gender. PMID:26035664

Cross-validation was performed in three random subsamples. Exploratory factor analysis using exploratory structural equation models was conducted in the first two subsamples to diagnose the factor structure, and confirmatory factor analysis was used in the third to corroborate the model defined by the exploratory analyses. Based on the 31 initial items, the model with the best fit included 25 items distributed across three dimensions. They all presented satisfactory convergent validity (values greater than 0.50 for the extracted variance) and precision (values greater than 0.70 for compound reliability). All factor correlations were below 0.85, indicating full discriminative factor validity. The RG scale presents acceptable psychometric properties and can be used in populations with similar characteristics.

    Platelet volume indices (PVI) are associated with hematological and non-hematological diseases, notably cardiovascular and cerebrovascular diseases. The establishment of PVI reference intervals (RIs) are essential to evaluate whether these indices are useful in clinical practice. Healthy-associated RIs have not yet been established for the Brazilian population. Here, we determined RIs of PVI for a health adult population, participants of the Brazilian Longitudinal Study of Adult Health ELSA-Brasil. A total of 580 individuals out of an initial sample of 3115 subjects constituted the healthy reference sample. To be part of the study, individuals had to fulfill the following criteria: blood count within 2 hours of collection, no use of continuous medication, self-rated health as good or very good, no reported diagnosis of diabetes and/or arterial hypertension, not smoking, lack of metabolic syndrome, body mass index (BMI) <30 kg/m(2), and platelet, hemoglobin, and creatinine beyond reference values. The RIs are mean platelet volume (MPV): 8.9-11.8 fL, platelet distribution width (PDW): 9.6-15.3 fL, platelet large cell ratio (P-LCR): 15.6-39.5%. These parameters were not significantly affected by age, gender, smoking, obesity, and alcohol abuse. However, significant differences were found among self-rated race/color groups. Standardization of measurement procedures and the establishment of healthy-associated PVI RIs are essential to be able to support clinical decision-making from laboratorial test results. This study at the baseline of the ELSA Brasil reported herein may contribute to future efforts aiming to evaluate whether PVI values are associated with clinical conditions in the Brazilian population.

    2016-04-01

    As laminated biogenic or abiogenic sedimentary structures [1], stromatolites record environmental changes along growth profiles, revealing possible changes in reservoir ages due to input of older carbon. A modern stromatolite sample was collected in Lagoa Vermelha (100 km east of Rio de Janeiro, Brasil) an area known for upwelling of South Atlantic Central Water (SACW). 34 samples from a transect cutting the lamination were collected with a hand-driller for standard geochemistry and 14C AMS analyses. Shells collected in 2015 were analysed for estimation of the present-day reservoir age. 14C ages of laminae and the reservoir age were used to apply the age-depth model to the stromatolite transect with the OxCal depositional model (Marine13 calibration curve; [2]). Small-scale changes in the composition of laminae report environmental changes, e.g. upwelling. The well-laminated middle part (laminated boundstone; ca. 4cm) of the stromatolite transect was found to have grown in a short time period of less than 100 years (1163-1210 14C y BP), with four excursions towards older 14C ages (ca. 1200 14C y BP). To detect possible changes of marine 14C, calendar years assuming a stable modern reservoir age were used to simulate atmospheric 14C ages with the southern hemisphere IntCal13 atmospheric calibration curve [3]. The offset between the measured and simulated 14C ages indicates a variability of the reservoir age between -99 and 268 14C y with highest reservoir correction found for the layers with indication of environmental changes (e.g. upwelling). Thus, this simulation confirms the occurrence of older carbon and points out the sensitivity of stromatolites for changing reservoir ages. [1] M.A. Semikhatov, C.D. Gebelein, P. Cloud, S.M.

    SUMMARY In this study, Leishmaniaspecies were identified by Polymerase Chain Reaction (PCR). The epidemiology of patients suspected of having American Cutaneous Leishmaniasis in the municipality of Assis Brasil, Acre State, located in the Brazil/Peru/Bolivia triborder was also investigated. By PCR, the DNA of Leishmaniawas detected in 100% of the cases (37 samples) and a PCR-Restriction Fragment Length Polymorphism (RFLP) of the hsp 70gene identified the species in 32 samples: Leishmania (Viannia) braziliensis (65.6%) , L. (V.) shawi (28.1%) , L. (V.) guyanensis (3.1%) and mixed infection L. (V.) guyanensis and L. (Leishmania) amazonensis (3.1%)This is the first report of L. (V.) shawiand L. (L.) amazonensis in Acre. The two predominant species were found in patients living in urban and rural areas. Most cases were found in males living in rural areas for at least three years and involved in rural work. This suggests, in most cases, a possible transmission of the disease from a rural/forest source, although some patients had not engaged in activities associated with permanence in forestall areas, which indicate a possible sandflies adaptation to the periurban setting.

    Background The MacArthur Scale of Subjective Social Status intend to measure the subjective social status using a numbered stepladder image. This study investigated the reliability of the MacArthur scale in a subsample of the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). Method Three scales were employed using different references: 1) the overall socioeconomic position; 2) the socioeconomic situation of the participant’s closer community; 3) the workplace as a whole. A total of 245 of the ELSA participants from six states were involved. They were interviewed twice by the same person within an interval of seven to fourteen days. The reliability of the scale was assessed with weighted Kappa statistics and intraclass correlation coefficient (ICC), with their respective 95% confidence interval (CI). Results Kappa values were 0.62(0.58 to 0.64) for the society ladder; 0.58(0.56 to 0.61) for the community-related ladder; and 0.67(0.66 to 0.72) for the work-related ladder. The ICC ranged from 0.75 for the work ladder to 0.64 for the community ladder. These values differed slightly according to the participants’ age, sex and education category. Conclusion The three ladders showed good stability in the test-retest, except the community ladder that showed moderate stability. Because the social structure in Brazil is rapidly changing, future qualitative and longitudinal studies are needed to confirm and understand the construct underlying the MacArthur Scale in the country.

    The primary aim of this study was to evaluate metabolically healthy status (MHS) among participants in obesity, overweight, and normal weight groups and characteristics associated with this phenotype using baseline data of Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). The secondary aim was to investigate agreement among 4 different MHS criteria. This cross-sectional study included 14,545 participants aged 35 to 74 years with a small majority (54.1%) being women. Of all participants, 22.7% (n = 3298) were obese, 40.8% (n = 5934) were overweight, and 37.5% (n = 5313) were of normal weight.Socio-demographic, behavioral, and anthropometric factors related to MHS were ascertained. Logistic regression models estimated the odds of associations. We used 4 different criteria separately and in combination to define MHS: the National Health and Nutrition Examination Survey (NHANES), the National Cholesterol Education Program (NCEP-ATPIII), the International Diabetes Federation (IDF) and comorbidities, and the agreement between them were evaluated by Cohen-kappa coefficient.MHS was present among 12.0% (n = 396) of obese, 25.5% (n = 1514) of overweight, and 48.6% (n = 2582) of normal weight participants according to the combination of the 4 criteria. The agreement between all the 4 MHS criteria was strong (kappa 0.73 P < 0.001). In final logistic models, MHS was associated with lower age, female sex, lower body mass index (BMI), and weight change from age 20 within all BMI categories.This study showed that, despite differences in prevalence among the 4 criteria, MHS was associated with common characteristics at every BMI category.

    Epicardial fat thickness (EFT) has emerged as a marker of cardiometabolic risk, but its clinical use warrants proper knowledge of its distribution and associations in populations. We aimed to describe the distribution of EFT, its demographic correlates and independent associations with diabetes, hypertension and metabolic syndrome (MS) in free-living Brazilian adults. From the baseline echocardiography of the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil)-a cohort study of civil servants aged 35-74 years-EFT was measured from a randomly selected sample of 998 participants as the mean of two paraesternal windows obtained at end systole (EFTsyst) and end diastole (EFTdiast). From the 421 individuals free of diabetes, hypertension and MS, we defined EFT reference values and the EFTsyst 75th percentile cut-off. Median EFTsyst was 1.5 (IQR 0-2.6) mm; a large proportion (84 %) had EFTdiast = 0. EFT was higher in women and lower in blacks, and increased with age and BMI. Although EFT was higher in those with diabetes, hypertension, and MS, EFT associations were reduced when adjusted for age, sex and ethnicity, and were non-significant after adjusting for obesity measures. In conclusion, the amount of EFT in this large multiethnic population is smaller than reported in other populations. EFT reference values varied across demographic and clinical variables, EFT associations with cardiometabolic variables being largely explained by age, sex, ethnicity and central obesity. Although EFT can help identify individuals at increased cardiometabolic risk, it will likely have a limited additional role compared to current risk stratification strategies.

    Night work has been suggested as a risk factor for diabetes. Individuals with high triglyceride levels, high LDL cholesterol, low HDL cholesterol and obesity, especially abdominal obesity, have a greater chance of developing diabetes. The aim of this study was to analyze glycemic levels, total cholesterol, HDL-C, LDL-C, triglycerides and the anthropometric alterations that precede diabetes, considering their possible association with nigh work among a non-diabetic population. Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) comprises of 15,105 civil servants (35-74 years old) at baseline (2008-2010). The following parameters were analyzed: serum cholesterol (total cholesterol, HDL-C, LDL-C), triglycerides and glucose drawn from 12-hour fasting blood sample, glycated hemoglobin and 2-hour plasma glucose obtained after a 75 g oral glucose tolerance test, BMI, hip and waist measurements using standard equipment and techniques. Participants with diabetes, retired workers and day workers with previous experience of night work were excluded. Generalized linear models, a gamma regression model with an identity link function, were performed to test the association of night work with metabolic and anthropometric variables. The study sample consisted of 3918 men and 4935 women; 305 (7.8%) and 379 (7.7%) of the participants were men and women who worked at night, respectively. Among the men, the exposure to night work was associated with an increase in BMI (b-value = 0.542; p = 0.032) and waist circumference (b-value = 1.66; p = 0.014). For women, increased fasting plasma glucose (b-value = 2.278; p < 0.001), glycated hemoglobin (b-value = 0.099, p < 0.001) and 2 hour plasma glucose (b-value = 5.479, p = 0.001) were associated with night work after adjustments. No significant associations between night work and triglycerides, LDL-C, HDL-C, total cholesterol levels or waist-hip ratio were found.

    The "Americano do Brasil" Complex (ABC) is part of a cluster of coeval synorogenic mafic-ultramafic intrusions emplaced during the Brasiliano/Pan-African Orogenic Cycle in Brazil. The medium-sized ABC consists of interlayered dunite, peridotite, websterite, and gabbronorite. High Fo values of olivine (up to Fo88) and the crystallization sequence of the ABC (Ol + Chr ≥ Ol + Opx + Chr ≥ Cpx + Opx ≥ Opx + Pl + Cpx ≥ Opx + Pl + Cpx + Ilm + Mag) suggest crystallization from tholeiitic high-MgO parental magmas. Light rare earth element (REE)-enriched mantle-normalized REE profiles and ɛNd(T) values of +2.4 for cumulate rocks from the ABC suggest a depleted mantle source for the parental magma. The ABC Ni-Cu sulfide deposit (3.1 Mt at 1.12 wt.% Ni and 1.02 wt.% Cu) consists of three distinctively different orebodies (S1, S2, and G2). The S2 orebody, an unusual occurrence of stratiform massive sulfide hosted by dunite and peridotite in the interior of a layered intrusion, results from sulfides accumulated at the transient base of the magma chamber following a new influx of parental magma. The G2 orebody has an irregular and roughly cylindrical shape, consisting mainly of net-textured sulfides. The G2 orebody is hosted by peridotite and pyroxenite and located stratigraphically below the S1 orebody. S2 and G2 orebodies are characterized by low Cu/Cu + Ni ratios (mainly below 0.4). The S1 orebody, hosted by websterite and gabbronorite in the more fractionated sequence of the ABC, is a cluster of several irregular discontinuous orebodies of Ni-Cu disseminated sulfides. The sulfides of the S1 orebody have high Cu/Cu + Ni ratios (mainly between 0.5 and 0.8) and are highly depleted in PGE. The S1 orebody is interpreted to result from a later event of sulfide segregation in the magma chamber, possibly following the event that originated the G2 orebody. The bulk of δ34S values for sulfides of the ABC orebodies and their host rocks fall in the range of 0 ± 2‰. Higher

    Background Stress is a typical migraine trigger. However, the impact of negative life events on migraine activity is poorly studied. The aim of this study is to investigate the association between negative life events and migraine using data from the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) baseline assessment. Methods ELSA-Brasil is a multicenter cohort study conducted in six Brazilian cities. Baseline assessment included validated questionnaires for headache classification and the occurrence of five pre-specified negative life events (financial hardship, hospitalization other than for childbirth, death of a close relative, robbery and end of a love relationship), focusing on a 12-month period before evaluation. We built crude and adjusted logistic regression models to study the association between the occurrences of negative life events and migraine diagnosis and activity. Results We included 4,409 individuals with migraine and 4,457 participants without headache (reference). After adjustment for age, sex, race, income and educational level, we found that the occurrence of a negative life event (Odds ratio = 1.31; 95% confidence interval = 1.19 – 1.45) was associated with migraine. However, after stratifying with subgroup analyses, only financial hardship (Odds ratio = 1.65; 95% confidence interval = 1.47 – 1.87) and hospitalization (Odds ratio = 1.47; 95% confidence interval = 1.25 – 1.72) were independently associated with migraine. Further adjustment for a current major depression episode and report of religious activity did not significantly change the results. Considering migraine frequency as (a) less than once per month, (b) once per month to once per week, or (c) more than once per week, financial hardship and hospitalization remained significantly associated with migraine in all episode frequency strata, with higher odds ratios for higher frequencies in adjusted models. We also observed a significant

    Background Carotid intima-media thickness (cIMT) has been used as an early marker of atherosclerotic disease in the general population. Recently its role among HIV-infected patients has been questioned. To date, no Brazilian study has compared cIMT in respect to HIV status. Methods We compared data from 535 patients actively followed in a prospective cohort in Rio de Janeiro (HIV group); 88 HIV-negative individuals who were nominated by patients (friend controls–FCs); and 10,943 participants of the ELSA-Brasil study. Linear regression models were used to study associations of the 3 groups and several covariables with cIMT. Propensity scores weighting (PSW) were also employed to balance data. Results Median thickness in mm (IQR) were 0.54 (0.49,0.62); 0.58 (0.52,0.68); and 0.57 (0.49,0.70), HIV, FCs and ELSA-Brasil groups, respectively (p-value<0.001). The best linear model chosen did not include the group variables, after adjusting for all the variables chosen, showing no difference of cIMT across groups. Similar results were obtained with PSW. Several traditional CVD risk factors were also significantly associated with cIMT: female gender, higher education and higher HDL were negatively associated while risk factors were older age, current/former smoker, AMI/stroke family history, CVD history, hypertension, DM, higher BMI and total cholesterol. Conclusions We show for the first time in a middle-income setting that cIMT, is not different in HIV-infected patients in Rio de Janeiro compared with 2 different groups of non-HIV-infected individuals. Traditional CVD risk factors are associated with this outcome. Our results point out that high standards of care and prevention for CVD risk factors should always be sought both in the HIV-infected and non-infected populations to prevent CVD-related events.

It is an exploratory and comprehensive study carried out in 2015, with tutors of the State of Santa Catarina, decentralized reference professionals of the Education and Health Ministries, and key reference professionals of the Education Ministry. Focus groups were used as the instrument for collection of data, through semi-structured interview. Based on the category Emergency care as a force of innovation in the Mais Médicos Program, the analysis was conducted from an ethical-political approach. Three fundamentals emerged: 'Putting out fires', 'Qualification of the Project', and 'the procedural point of view'. It was concluded that academic tutorship of the productive activities of doctors in emergency care is not an isolated pedagogical approach, since it is a part and a consequence of the historic development of the theory and of the practice. The activity corresponds, dialectically, to movements of rupture, resistance, emancipation and also requires collective reflection about the values chosen and achieved in the acts of decision.

    Doctor shortage is a constant problem in smaller cities and towns, which tend to be more vulnerable from a social and economic point of view, and located in geographically isolated areas. The goal of this study was to establish the share and characteristics of the small cities and towns in the macro-region of northern Paraná that subscribed to the Mais Médicos para o Brasil (PMMB) program. This is a quantitative study of 82 cities and towns using primary and secondary data. Results show that only a few of them (6.1%) had any adherence criteria, which was not an impediment for other cities and towns (75%) to adhere to the project. Cities and towns with over five thousand inhabitants, lower municipal HDI (Human Development Index), some adherence criteria and more geographically isolated, either from the main city in the region or the closest large or mid-sized city, tended to adhere to the PMMB. It is undeniable that the PMMB significantly reduced the uneven distribution of doctors in Brazil and the study region. However, the sustainability of this policy is linked to addressing other remaining challenges in the SUS system.

Of the 15 105 patients who enrolled in the study, we analyzed 3412 after excluding those who reported previous cardiovascular diseases, diabetes, or hypertension; were heavy drinkers; or had a body mass index (BMI) ≥ 35 kg/m(2). Among the men, logistic regression, adjusted for age, race, income, birth weight, salt intake, insulin resistance, BMI, and renal function revealed odds ratios (ORs) and 95% confidence intervals (CIs) of prehypertension from the bottom quartile (referent) to the top quartile of SUA levels as follows: 0.84 (95% CI, 0.61-1.38), 0.97 (0.71-1.34) and 1.44 (1.04-2.0; P for trend .01). Analyzing for 1-standard deviation of change in SUA, the ORs were 1.19 (1.06-1.32). This association persisted in the subgroup analysis consisting of patients who were white, overweight, with a high salt intake but with normal renal function, and without metabolic syndrome. No association was found among women. In conclusion, SUA levels were associated with prehypertension among men.

    Despite the process of nutritional transition in Brazil, in some places, such as the Amazon region, stunting is still an important public health problem. We identified the prevalence and factors associated with stunting in children under five years old residing in the urban area of Assis Brasil. A survey was conducted in which a questionnaire on socioeconomic, maternal and children's conditions was applied, and height or length was measured. The children with height for age index below -2 Z-scores were considered stunted, according to the criteria by the World Health Organization. Four hundred and twenty-eight children were evaluated. Of these, 62 were stunted. Factors associated with stunting, according to adjusted models, were: the presence of open sewer, the wealth index for households, the receipt of governmental financial aid and the mother's height, age and education. Therefore, it was observed that family and the mother's characteristics as well as environmental and socioeconomic factors were closely related to the occurrence of stunting in the population studied, and such nutritional disturbance is still a health problem in the Brazilian Amazon.

    The Amazon Basin is categorized as a terrestrial biogeochemical "hotspot" where climate change and deforestation can trigger substantial changes on atmospheric CO. However, model skill at predicting seasonality of photosynthetic metabolism and ecosystem productivity in the Amazon is limited. To enhance our understanding of these processes, we investigated the seasonal and spatial patterns of Amazonian forest photosynthetic activity by integrating data from a network of ground-based eddy flux towers in Brazil established as part of the ‘Large-Scale Biosphere Atmosphere Experiment in Amazonia' project. We present the results of a simple model of leaf-flush for two central Amazon BrasilFlux sites, based on the eddy covariance estimates of canopy photosynthetic capacity (Pc) and measured canopy structure parameters. We found that in contrast to studies of Amazon evapotranspiration, which is highly correlated with available energy, Amazon ecosystem photosynthetic flux surprisingly showed no simple relationship with measures of available energy. We hypothesize that the seasonality of Amazon photosynthesis is controlled by the interaction of adaptive mechanisms (which biologically determine photosynthetic capacity through leaf flush and litter fall seasonality) and sunlight availability (which determines the fraction of photosynthetic capacity utilized). Equatorial climates advantage vegetation that can grow leaves in the dry season, when surface solar radiation peaks, but southerly sites may not because of reduced seasonality in surface radiation.

    Suicidal ideation represents an important burden worldwide. However, little is known about it in low-/middle-income countries. We investigated this issue in a large cross-sectional of Brazilian civil servants (ELSA-Brasil, the Brazilian Health Longitudinal Study, n=15,105). Logistic univariate and multivariate analyses were performed to evaluate the strength of association (odds ratio, OR) between clinical and sociodemographic variables with acute life-weariness (tiredness of life) and suicidal thoughts. The presence of major depressive disorder (MDD), common mental disorders (CMDs), stressful life-events (SLEs) and poor self-perceived physical health was also collected. MDD and CMDs were strongly associated with suicidal ideation in univariate and multivariate analyses. For life-weariness thoughts, a modest, consistent association was found for female gender, being single, non-White ethnicity and poor education. SLEs and poor self-perceived physical health were also associated with suicidal ideation. Espiritism-Kardecism, but not other religions or Atheism/Agnosticism, was associated with lower rates of life-weariness and suicidal thoughts. To conclude, suicidal ideation does not differ in Brazil compared to developed countries, being primarily associated with psychiatric disorders and, to a lesser but significant extent, to social disadvantage, SLEs, poor self-perceived health and being single.

    Background Vascular dysfunction is an early expression of atherosclerosis and predicts cardiovascular (CV) events. Peripheral arterial tonometry (PAT) evaluates basal pulse amplitude (BPA), endothelial function (PAT ratio), and wave reflection (PAT‐AIx) in the digital microvessels. In Brazilian adults, we investigated the correlations of PAT responses to CV risk factors and to carotid‐femoral pulse wave velocity (PWV), a measure of arterial stiffness. Methods and Results In a cross‐sectional study, 1535 participants of the ELSA‐Brasil cohort underwent PAT testing (52±9 years; 44% women). In multivariable analyses, more‐impaired BPA and PAT ratios were associated with male sex, higher body mass index (BMI), and total cholesterol/high‐density lipoprotein. Higher age and triglycerides were related to higher BPA, whereas lower systolic blood pressure, hypertension (HTN) treatment, and prevalent CV disease (CVD) were associated with lower PAT ratio. PAT‐AIx correlated positively with female sex, advancing age, systolic and diastolic blood pressures, and smoking and inversely to heart rate, height, BMI, and prevalent CVD. Black race was associated with lower BPA, higher PAT ratio, and PAT‐AIx. Microvessel vasodilator function was not associated with PWV. Higher PAT‐AIx was modestly correlated to higher PWV and PAT ratio and inversely correlated to BPA. Conclusion Metabolic risk factors are related to impaired microvessel vasodilator function in Brazil. However, in contrast to studies from the United States, black race was not associated with an impaired microvessel vasodilator response, implying that vascular function may vary by race across populations. PAT‐AIx relates to HTN, may be a valid measure of wave reflection, and provides distinct information from arterial stiffness. PMID:25510401

  2. Earlier age at menarche is associated with higher diabetes risk and cardiometabolic disease risk factors in Brazilian adults: Brazilian Longitudinal Study of Adult Health (ELSA-Brasil)

    Objectives Early menarche has been linked to higher risk of type 2 diabetes in Western and Asian societies, yet whether age at menarche is associated with diabetes in Latin America, where puberty and diabetes may have different life courses, is unknown. We tested the hypothesis that earlier menarche is associated with higher diabetes risk in Brazilian adults. Methods We used data from 8,075 women aged 35-74 years in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) who had complete information on age at menarche, diabetes status, and covariates. Diabetes was defined based on self-reported physician diagnosis, medication use, and laboratory variables (fasting glucose, 2-hour glucose, and glycated hemoglobin). Poisson regression was used to generate risk ratios (RR) and 95% confidence intervals (CI). Results Menarche onset < 11 years [vs. 13-14 years (referent)] was associated with higher risk of diabetes (RR = 1.34; 95% CI: 1.14-1.57) after adjusting for sociodemographic factors, maternal education, maternal and paternal diabetes, and birth weight. This persisted after further control for BMI at age 20 years and relative leg length. Additionally, among those not taking diabetes medications, earlier menarche [<11 years vs. 13-14 years (referent)] was associated with higher % glycated hemoglobin (p < 0.001), alanine aminotransferase (p < 0.001), triglycerides (p < 0.001), C-reactive protein (p = 0.003), waist circumference (p < 0.001), and BMI measured at baseline exam (p < 0.001). Conclusion These findings support the hypothesis that earlier menarche is associated with greater risk for adult diabetes and cardiometabolic disease in the Brazilian context. PMID:24438044

    Thyroid diseases are common, and use of levothyroxine is increasing worldwide. We investigated the influence of gender, race and socioeconomic status on the diagnosis and treatment of thyroid disorders using data from the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil), a multicenter cohort study of civil servants (35-74 years of age) from six Brazilian cities. Diagnosis of thyroid dysfunction was by thyrotropin (TSH), and free thyroxine (FT4) if TSH was altered, and the use of specific medications. Multivariate logistic regression models were constructed using overt hyperthyroidism/hypothyroidism and levothyroxine use as dependent variables and sociodemographic characteristics as independent variables. The frequencies of overt hyper- and hypothyroidism were 0.7 and 7.4%, respectively. Using whites as the reference ethnicity, brown, and black race were protective for overt hypothyroidism (OR=0.76, 95%CI=0.64-0.89, and OR=0.53, 95%CI=0.43-0.67, respectively, and black race was associated with overt hyperthyroidism (OR=1.82, 95%CI=1.06-3.11). Frequency of hypothyroidism treatment was higher in women, browns, highly educated participants and those with high net family incomes. After multivariate adjustment, levothyroxine use was associated with female gender (OR=6.06, 95%CI=3.19-11.49) and high net family income (OR=3.23, 95%CI=1.02-10.23). Frequency of hyperthyroidism treatment was higher in older than in younger individuals. Sociodemographic factors strongly influenced the diagnosis and treatment of thyroid disorders, including the use of levothyroxine. PMID:26108100

    High blood pressure (HBP) is the leading risk factor for years of life lost in Brazil. Factors associated with HBP awareness, treatment and control need to be understood better. Our aim is to estimate prevalence, awareness, and types of anti-hypertensive treatment and to investigate the association of HBP control with social position. Data of 15,103 (54% female) civil servants in six Brazilian state capitals collected at the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) baseline (2008-2010) were used to estimate prevalence and cross-sectional association of HBP control with education, per capita family income and self-reported race, using multiple logistic regression. Blood pressure was measured by the oscillometric method. 35.8% were classified as presenting HBP; 76.8% of these used anti-hypertensive medication. Women were more aware than men (84.8% v. 75.8%) and more often using medication (83.1% v. 70.7%). Adjusted HBP prevalence was, in ascending order, Whites (30.3%), Browns (38.2%) and Blacks (49.3%). The therapeutic schemes most used were angiotensin-converting enzyme inhibitors, in isolation (12.4%) or combined with diuretics (13.3%). Among those in drug treatment, controlled blood pressure was more likely in the (postgraduate) higher education group than among participants with less than secondary school education (PR = 1.21; 95% CI: 1.14–1.28), and among Asian (PR = 1.21; 95% CI: 1.12–1.32) and ‘Whites (PR = 1.19; 95% CI: 1.12–1.26) compared to Blacks. Socioeconomic and racial inequality—as measured by different indicators—are strongly associated with HBP control, beyond the expected influence of health services access. PMID:26102079

    Introduction Observational studies have reported fairly consistent inverse associations between coffee consumption and risk of type 2 diabetes, but this association has been little investigated with regard to lesser degrees of hyperglycemia and other alterations in glucose homeostasis. Additionally, the association between coffee consumption and diabetes has been rarely investigated in South American populations. We examined the cross-sectional relationships of coffee intake with newly diagnosed diabetes and measures of glucose homeostasis, insulin sensitivity, and insulin secretion, in a large Brazilian cohort of middle-aged and elderly individuals. Methods We used baseline data from 12,586 participants of the Longitudinal Study of Adult Health (ELSA-Brasil). Logistic regression analyses were performed to examine associations between coffee consumption and newly diagnosed diabetes. Analysis of covariance was used to assess coffee intake in relation to two-hour glucose from an oral glucose tolerance test, fasting glucose, glycated hemoglobin, fasting and –2-hour postload insulin and measures of insulin sensitivity. Results We found an inverse association between coffee consumption and newly diagnosed diabetes, after adjusting for multiple covariates [23% and 26% lower odds of diabetes for those consuming coffee 2–3 and >3 times per day, respectively, compared to those reporting never or almost never consuming coffee, (p = .02)]. An inverse association was also found for 2-hour postload glucose [Never/almost never: 7.57 mmol/L, ≤1 time/day: 7.48 mmol/L, 2-3 times/day: 7.22 mmol/L, >3 times/day: 7.12 mol/L, p<0.0001] but not with fasting glucose concentrations (p = 0.07). Coffee was additionally associated with 2-hour postload insulin [Never/almost never: 287.2 pmol/L, ≤1 time/day: 280.1 pmol/L, 2–3 times/day: 275.3 pmol/L, >3 times/day: 262.2 pmol/L, p = 0.0005) but not with fasting insulin concentrations (p = .58).

    Objetivos. Examiné los efectos combinados del acceso a la atención primaria mediante el Programa de Salud Familiar (PSF) y las transferencias condicionadas de dinero en efectivo del Programa Bolsa Familia (PBF) sobre la mortalidad infantil posneonatal (MIPN) en Brasil. Métodos. Empleé un análisis ecológico longitudinal usando datos en panel de 4 583 municipios brasileños de 1998 al 2010, con 54 253 observaciones en total. Estimé modelos de regresión de efectos fijos por mínimos cuadrados ordinarios, con la tasa de MIPN como la variable dependiente y el PSF, el PBF y sus interacciones como las principales variables independientes de interés. Resultados. La asociación de una mayor cobertura del PSF con una menor tasa de MIPN se volvió más fuerte conforme aumentaba la cobertura del PBF. En los promedios de todas las demás variables, cuando la cobertura de PBF era 25%, la MIPN predicha fue 5,24 (intervalo de confianza [IC] de 95% = 4,95, 5,53) para una cobertura del PSF de 0%, y de 3,54 (IC de 95% = 2,77, 4,31) para una cobertura del PSF de 100%. Cuando la cobertura del PBF era de 60%, la MIPN predicha fue 4,65 (IC de 95% = 4,36, 4,94) para una cobertura del PSF de 0%, y de 1,38 (IC de 95% = 0,88, 1,89) para una cobertura del PSF de 100%. Conclusiones. El efecto del PSF depende de la ampliación del PBF. Para las poblaciones empobrecidas y subatendidas, la combinación de intervenciones tanto del lado de la oferta como del lado de la demanda podría ser necesaria para mejorar los resultados en salud.

"Geolover" is a multitouch game, played by four players simultaneously, identified by 4 mascots and using as sceneries, the four regions landscapes, aimed to the young people with ages between 8 and 12 years old. The main objective is value the geological heritage of the Ilha do Fogo (Cabo Verde), Seridó in State of Rio Grande do Norte (Brasil) , Sabugal in Beira Alta province (Portugal) and Arquipélago dos Açores (Portuguese autonomous region). These regions have a great geological heritage like volcanology, plutonic rocks, sedimentar formations, metamorphic, paleontologic, mineralogic, geomorphologic, hydric and mining resources. Such heritage is being used in the different regions has base of studies to senior scientists and were used to great scientific researches. The diversified and distinguished cultural heritage of these four regions is referenced and it's a value to the union of the students from these three continents, with the Portuguese language as communication tool. The variety of the geological wealth and cultural of these regions, results in the common objective of their valuing like Geoparks. His creation on these three regions is a strategy with a great relevance to the socio-economic development. With the creation of this game, we promote the union of these 3 countries from these three continents, the universal values of the heritage richness that are offered by our planet.

    Background: Associations between major depressive disorder (MDD) and coronary heart disease (CHD) have been established, and these associations increase risk of future morbidity and mortality. Prior research has been carried out in high-income countries. Here we examine associations between the mood and anxiety disorders, and CHD in a large cohort at baseline from Brazil, a country facing a variety of challenges that may affect these associations. Methods: Participants included 15,105 civil servants aged 35 to 74 at baseline (2008–2010) from the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). CHD (N = 721) included self-reported angina pectoris (n = 305), myocardial infarction (n = 259) and coronary revascularization (n = 239). Hierarchical logistic regression analyses were conducted to estimate odds ratios and confidence intervals. Results: Major findings indicate that comorbid MDD and anxiety disorders (n = 434) are associated with a threefold increase in CHD, MDD alone (n = 170) with a twofold increase in CHD, while generalized anxiety disorder alone (n = 1,394) and mixed anxiety and depression disorder (n = 1,844) – symptoms present, but diagnostic threshold not reached – are associated with a 1.5-fold increase in CHD, after full adjustment for covariates. Conclusion: The association with CHD is greatest in those with psychiatric comorbidity, while associations were also observed in MDD and generalized anxiety disorder without comorbidity. While findings are limited by the cross-sectional design of the study, given the known risks associated with comorbidity of the mood and anxiety disorders with CHD, findings reinforce the importance of comprehensive health assessment in Brazil.

    Background Chronic inflammation has been postulated to be one mediating mechanism explaining the association between low socioeconomic position (SEP) and cardiovascular disease (CVD). We sought to examine the association between life course SEP and C-reactive protein (CRP) levels in adulthood, and to evaluate the extent to which health-risk behaviors and metabolic alterations mediate this association. Additionally, we explored the possible modifying influence of gender. Methods and Findings Our analytical sample comprised 13,371 participants from ELSA-Brasil baseline, a multicenter prospective cohort study of civil servants. SEP during childhood, young adulthood, and adulthood were considered. The potential mediators between life course SEP and CRP included clusters of health-risk behaviors (smoking, low leisure time physical activity, excessive alcohol consumption), and metabolic alterations (obesity, hypertension, low HDL, hypertriglyceridemia, and diabetes). Linear regression models were performed and structural equation modeling was used to evaluate mediation. Although lower childhood SEP was associated with higher levels of CRP in adult life, this association was not independent of adulthood SEP. However, CRP increased linearly with increasing number of unfavorable social circumstances during the life course (p trend <0.001). The metabolic alterations were the most important mediator between cumulative SEP and CRP. This mediation path accounted for 49.5% of the total effect of cumulative SEP on CRP among women, but only 20.2% among men. In consequence, the portion of the total effect of cumulative SEP on CRP that was mediated by risk behaviors and metabolic alterations was higher among women (55.4%) than among men (36.8%). Conclusions Cumulative SEP across life span was associated with elevated systemic inflammation in adulthood. Although health-risk behaviors and metabolic alterations were important mediators of this association, a sizable fraction of this

Both radial (R) and transverse (T) components of the RF contain useful information about the subsurface structure. The isotropic part of the seismic velocity profile at depth mainly affects the R-RF component, while anisotropy and dipping structures produce P-to-S conversion recorded on the T-RF component (Levin and Park, 1998; Savage, 1998). The incoming (radially polarized) S waves, when passing through an anisotropic crust, splits and part of it is projected onto the transverse component. The anisotropy symmetry orientations (Φ) can be estimated by the polarity change of the observed phases. The arrival times of the phases is related to the depth of the conversion. Depth and Φ are estimated by isolating phases at certain arrival times. SKS shear-wave splitting results from previous studies in this area (Krüger et al., 2002, Rosa et al., 2014), suggest the presence of anisotropy in the mantle with orientation of the fast splitting axis (about E-W) following major deep tectonic structures. The observed splitting orientation correlates well with the current South America plate motion (i.e. relative to mesosphere), and with observed aeromagnetic trends. This similarity leaves open the possibility of a linkage between the upper mantle fabric imaged by shear wave splitting analysis and the lower crustal structure imaged by aeromagnetometry. In this study we unravel, from RF data, two layers in which anisotropy concentrates, i.e. the lower crust and the upper mantle. Lower crustal and upper mantle anisotropy retrieved by RFs give some new hints in order to interpret the previously observed anisotropic orientations from SKS and the aeromagnetic anomalies.

    Uma das partes mais importantes de um satélite é o controle de atitude do mesmo. E se tratando de um satélite científico, a atenção para este sistema deve ser redobrada. Uma possibilidade atraente para executar esta tarefa é a propulsão elétrica. Aqui, mostraremos resultados obtidos pelo propulsor à plasma PHALL-01, desenvolvido na Universidade de Brasília entre 2000 e 2003. Este é derivado do propulsor russo SPT-100 (Stationary Plasma Thruster), mas com o emprego inovador de um arranjo de imãs permanentes como fonte do campo magnético, este último o agente da aceleração do plasma. Esta alteração foi motivada pelo objetivo de que o mesmo operasse com o mínimo de potência elétrica. A partir da formulação teórica do mecanismo de aceleração, tendo como base as equações da magnetohidrodinâmica, pode-se obter vínculos sob os quais o propulsor pudesse ser construído. O mais forte destes é o que dita a topologia do campo magnético. Sendo assim, foram realizadas simulações computacionais, que definiram a geometria do propulsor. Após construído, este foi diagnosticado usando-se sondas de Langmuir e analisadores de energia. Como resultados, obtivemos a distribuição espacial da temperatura, densidade e potencial do plasma, bem como a distribuição angular do feixe produzido pelo mesmo em vários regimes de operação. O espectro de energia do feixe de plasma também foi medido, indicando íons de até 560eV. Combinando estes resultados, calculou-se o empuxo do propulsor: 84mN; e o impulso específico: 1083s. Estes demonstram que o mesmo estará qualificado, num futuro próximo, para o emprego no controle de atitude de satélites científicos, ou até mesmo como parte do conjunto propulsor primário, responsáveis pela transferência de órbitas.

    A small airplane fatal accident has occurred near Maceio Airport, on the coastal region on 26 July 2007. Low visibility in the intensive fog has provoked this accident. Weather forecast analysis, published in the local and central Brazilian newspapers during 2007, showed fog forecast absence during whole year. A study of the fog formation causes was elaborated using the high and low resolution satellite data, radar data, different products of NCEP reanalysis data and high resolution regional MM5 model simulation. The trade winds with a weak cyclonic curvature at the low levels have generated the humidity convergence at the superficial layers up to 850hPa on the coastal region. An anticyclonic circulation existence at the middle and higher levels and weak ascendant motion (by NCEP data) have support a weak convection development. The low levels clouds development on the continental region and convection development over ocean were confirmed by the radar and satellite data. A thermal inversion near surface level (up to 150m) and descendent movement at the middle and high levels were identified by MM5 model. Fog formation was simulated by PAFOG model. The conventional airport observations have shown the minimal visibility of 200m between 4 and 7a.m. Moreover visibility less than 1000m between 1 and 8a.m. with the minimal visibility of 213m was simulated by PAFOG model.

    This article is the result of a research on basic training in Astronomy in physics degrees that performed the ENADE 2011 national examination. The objective was to identify whether there are disciplines of Astronomy in these courses, whether are mandatory or optional, its workload and when it is offered. The relationship between astronomers, physics degrees and disciplines of Astronomy was investigated. To perform this research we examined the results of ENADE 2011 and also the census of Brazilian Astronomical Society. As a result it is observed that in only 15% of the courses there is a mandatory subject of Astronomy, and therefore there is a high probability that 85% of physics teachers trained in 2011 have not had any discipline of Astronomy during their graduation. In addition, the data collected in this study shows a low number of members of SAB (Sociedade Astronômica Brasileira) among the surveyed courses. We have verified that the presence of astronomers in a given university does not imply to have a mandatory discipline of Astronomy in physics degrees at the same university. Este artículo es el resultado de una investigación sobre la formación básica en Astronomía en los cursos de Profesorado en Física que hicieron el examen nacional ENADE 2011.

    Background After hearing about the reproducible and excellent results of the Ponseti method for clubfoot treatment, a group of Brazilian orthopaedic surgeons organized and participated in a standardized national program to teach the Ponseti technique in 21 different cities across Brazil. Methods A total of 21 Ponseti symposiums were organized in a standard fashion from January, 2007 to December, 2008. They consisted of a two-day program with lectures, hands-on cast application, and discussion of local clinical cases presented by orthopaedic surgeons. Thirteen Brazilian orthopaedic surgeons, who had been trained by the University of Iowa or centers recognized by them, taught the method. Financial support for travel was provided by an English charity: La Vida (Vital Investment for Developing Aid in Latin America). The physicians who attended the symposiums answered questionnaires before and after the training. Results About 7% of the 8000 orthopaedic surgeons in Brazil (556 orthopaedic surgeons) were trained. These orthopaedic surgeons stated that they had treated about 4905 babies in the previous year via other methods, including extensive surgery. Seventeen percent of the surgeons did not know about the Ponseti technique at the start of the symposium. Eighty-eight percent reported they felt able to treat children with the Ponseti technique after the symposium. Ninety-four percent of respondents reported that the symposium changed their way of treating clubfoot Conclusions These Ponseti symposiums brought about an exchange of medical information and empowered the participants. This program is a good educational tool which can be used in eradicating neglected clubfoot in Brazil. PMID:22096418

    This paper aims to demonstrate the evolution of a study in the city of Juiz de Fora-MG, whose objective is the assessment of areas of train station in relation to the inclusion of people with disabilities and consequently promote the historical and cultural heritage of this city. The railway buildings are important landmarks in the history of the city and its surroundings was formed the first core of urban development. Because this building was of the early nineteenth century, these were not designed to assist people with disabilities, in effect, we observed that the buildings are being underutilized. The difficulty of insertion of incentive policies is therefore not due to the commitment by the majority, making the deployment of new access.

    This study examined the effect of population characteristics and geographic location of residences and services on the odds of receiving a mammography in 2003 and 2008. Patterns of mammography use were analyzed using data from the Health Supplements of the National Household Sample Survey for women aged over 25, using prevalence ratios, and for women over 40 using multivariate logistic regression, correcting for complex sample design effects. In 2003, 54.6% of women of 50-69 years of age reported having had a mammography, in 2008, 71.5%. The odds are higher for those 50 to 69 years old, and increase with family income, education, being married, having consulted a doctor and having health insurance. Living in a metropolitan area trebles the chance of mammography. Compared to the Northern region, residents in all other regions have greater odds, greater distances decrease the odds. Coverage increased in the age range targeted by national policy, and inequalities due to income and education on access to mammography were reduced but regional convergence was not marked. Increased access seems to relate more to policies of income distribution and social inclusion, and to the availability of the examination in the Unified Health System, than to an increasing number of mammography units.

  12. Does offshore crustal taper control an onshore topographic displacement gradient in SE Brasil?

    2015-04-01

    The SE Brasilian Serras da Mantiqueira and do Mar topographic envelopes exhibit coast-parallel displacement gradients typical of linked normal faults in extending terrain. Between southern Curitiba and Cabo Frio, coast-perpendicular profiles show the distance from the maximum escarpment elevation to the likely location of the extended margin's flexural/rheological coupling point (Taper Break, or TB) is inversely correlative to the height of the escarpment. The correlation is similar to previously-published scaling relationships derived from Scandinavian and global datasets. Although Precambrian ductile shear zones guided brittle phase faulting during Mesozoic extension and Cenozoic margin uplift, the primary control governing fault reactivation and source-to-sink evolution of the SE Brasilian rifted margin seems rooted in crustal thinning. We see two lines of interest for petroleum exploration: Preferential reactivation of high angle faults at sharply-tapered margin sectors is expected to guide onshore to offshore sediment routing along margin-parallel corridors, and (should the TB-escarpment correlation be better validated with proposed analyses of high-quality marine geophysical datasets) a partial constraint upon architectural end member interpretations of deep crustal structure may be contemplated.

  14. Zooming into the Paraná-Etendeka silicic volcanics, southern Brasil: a physical volcanological approach

    Paraná-Etendeka volcanism led to the opening of the Atlantic Ocean during the early Cretaceous. Most Paraná research has focused on the regional scale geochemistry and geochronology. Complementarily, we have taken a physical volcanological approach to elucidate the styles and locations of silicic eruptions with a focus on extrusive vs. explosive varieties, and an ultimate goal to characterise the crustal magmatic conditions. Through satellite to microscopic observations we can zoom from volcanic edifice and deposit morphologies, remarkably preserved in the Mesozoic landscape, to primary microscopic textures. Lava domes appear in clusters with high relief and are surrounded by lower flat-topped terraces comprised of multiple tabular-shaped packages with conspicuous horizontal jointing. Joint thickness coincides with layering from mm-scale laminations to larger lens-shaped blobs up to 20 cm thick and more than a metre long. These layered deposits appear to be compressed and/or stretched into the finer laminations and grade up into the fatter lens-shaped blobs. In other regions, extensive plateaus dominate the landscape with flat-lying flow packages continuous over 10's of kilometres and possibly further. Rheomorphism is evident in places with sub-parallel joints that grade up into a zone of deformation where curvilinear to overturned joint patterns reflect lateral forcing in a more ductile flow regime. Microscopically the blobs and surrounding matrix are almost indistinguishable except for subtle differences in spherulite textures, zonal alteration and distribution of crystal sizes. Although our research is relatively nascent, our observations suggest eruptions may have ranged from edifice building effusive ones to more explosive ones, albeit possibly relatively low fire fountains feeding hybridised lava/pyroclastic flows. Some of these flows are extensive, tens to possibly hundreds of kilometres long, consistent with high eruption rates of hot magma. These interpretations are consistent with published temperatures as hot as 1050 degrees for these silicic magmas. Preliminary work focusing on glass compositions and coexisting phase assemblages within the blobs reveals that silicic magmas resided in the shallow crust prior to eruption.

  15. Lignin phenols used to infer organic matter sources to Sepetiba Bay - RJ, Brasil

    Lignin phenols were measured in the sediments of Sepitiba Bay, Rio de Janeiro, Brazil and in bedload sediments and suspended sediments of the four major fluvial inputs to the bay; São Francisco and Guandu Channels and the Guarda and Cação Rivers. Fluvial suspended lignin yields (Σ8 3.5-14.6 mgC 10 g dw -1) vary little between the wet and dry seasons and are poorly correlated with fluvial chlorophyll concentrations (0.8-50.2 μgC L -1). Despite current land use practices that favor grassland agriculture or industrial uses, fluvial lignin compositions are dominated by a degraded leaf-sourced material. The exception is the Guarda River, which has a slight influence from grasses. The Lignin Phenol Vegetation Index, coupled with acid/aldehyde and 3.5 Db/V ratios, indicate that degraded leaf-derived phenols are also the primary preserved lignin component in the bay. The presence of fringe Typha sp. and Spartina sp. grass beds surrounding portions of the Bay are not reflected in the lignin signature. Instead, lignin entering the bay appears to reflect the erosion of soils containing a degraded signature from the former Atlantic rain forest that once dominated the watershed, instead of containing a significant signature derived from current agricultural uses. A three-component mixing model using the LPVI, atomic N:C ratios, and stable carbon isotopes (which range between -26.8 and -21.8‰) supports the hypothesis that fluvial inputs to the bay are dominated by planktonic matter (78% of the input), with lignin dominated by leaf (14% of the input) over grass (6%). Sediments are composed of a roughly 50-50 mixture of autochthonous material and terrigenous material, with lignin being primarily sourced from leaf.

    Over the past few years, one of the most productive directions in the study of the activation and application of stereotypes has been provided by the essentialist concept of categorization. The research presented here studied the impact of two dimensions of essentialist beliefs--naturalism and entitativity-by using data collected from Brazil, Spain and England. The aim was to test whether there was a greater degree of essentialization among the naturalizable categories (sex, age and race) than among the entitative categories (economic condition, religion, political orientation, nationality and social condition). The results not only showed that participants hold more essentialist beliefs with regard to naturalistic categories but also showed the differences in the degree of essentialization across the three cultures. A discussion is conducted on the implications of the present findings, and on the heuristic value of the theoretical model (of the bidimensional nature of essentialism) adopted by this research.

    We evaluated seasonal species presence and richness, and abundance of medium and large sized mammalian terrestrial fauna in the "Mário Viana" Municipal Biological Reserve, Nova Xavantina, Mato Grosso, Brazil. During 2001, two monthly visits were made to an established transect, 2,820 m in length. Records of 22 mammal species were obtained and individual footprint sequences quantified for seasonal calculation of species richness and relative abundance index (x footprints/km traveled). All 22 species occurred during the rainy season, but only 18 during the dry season. Pseudalopex vetulus (Lund, 1842) (hoary fox), Eira barbara (Linnaeus, 1758) (tayra), Puma concolor (Linnaeus, 1771) (cougar) and Hydrochaeris hydrochaeris (Linnaeus, 1766) (capybara) were only registered during the rainy season. The species diversity estimated using the Jackknife procedure in the dry season (19.83, CI = 2.73) was smaller than in the rainy season (25.67, CI = 3.43). Among the 18 species common in the two seasons, only four presented significantly different abundance indexes: Dasypus novemcinctus Linnaeus, 1758 (nine-banded armadillo), Euphractus sexcinctus (Linnaeus, 1758) (six-banded armadillo), Dasyprocta azarae Lichtenstein, 1823 (Azara's Agouti) and Tapirus terrestris (Linnaeus, 1758) (tapir). On the other hand, Priodontes maximus (Kerr, 1792) (giant armadillo) and Leopardus pardalis (Linnaeus, 1758) (ocelot) had identical abundance index over the two seasons. Distribution of species abundance in the sampled area followed the expected pattern for communities in equilibrium, especially in the rainy season, suggesting that the environment still maintains good characteristics for mammal conservation. The present study shows that the reserve, although only 470 ha in size, plays an important role for conservation of mastofauna of the area as a refuge in an environment full of anthropic influence (mainly cattle breeding in exotic pasture).

    The A. presents a preliminary report concerning on the histologic patterns of an anthracotic pneumoconiosis found in necropsies of the "Hospital Universitário da Universidade de Londrina", Paraná, Brazil, and in some cases from the Legal Institute of the same town. The lesions, on its histologic pattern are comparable to those observed in the lung of coal and iron mines workers as described in the consulted literature. The cases studied (plantations workers and dwellers at rural and suburban areas) are proceeding from an essencially agricultural region, without detectable polluition by industry or others known factors. This agricultural zone presents some geophysic peculiarities and dust from the errosive soil, is a constant factor in the local athmosphere. The soil is so called "Terra Roxa" (red soil) and in its physicochemical composition there is a great amount of iron oxides, silica (silt, agril laceous material), aluminium, manganese, organic compounds. In this preliminary report the A. suggests further research for a better knowledge of the composition of the respirable air and if dust exposures are or not responsible for the lung lesions.

The present study shows that the reserve, although only 470 ha in size, plays an important role for conservation of mastofauna of the area as a refuge in an environment full of anthropic influence (mainly cattle breeding in exotic pasture).

    Objetivo Descrever a evolução da mortalidade por homicídios no Município de São Paulo segundo tipo de arma, sexo, raça ou cor, idade e áreas de exclusão/inclusão social entre 1996 e 2008. Métodos Estudo ecológico de série temporal. Os dados sobre óbitos ocorridos no Município foram coletados da base de dados do Programa de Aprimoramento das Informações sobre Mortalidade, seguindo a Classificação Internacional de Doenças, Décima Revisão (CID-10). Foram calculadas as taxas de mortalidade por homicídio (TMH) para a população total, por sexo, raça ou cor, faixa etária, tipo de arma e área de exclusão/inclusão social. As TMH foram padronizadas por idade pelo método direto. Foram calculados os percentuais de variação no período estudado. Para as áreas de exclusão/inclusão social foram calculados os riscos relativos de morte por homicídio. Resultados As TMH apresentaram queda de 73,7% entre 2001 e 2008. Foi observada redução da TMH em todos os grupos analisados, mais pronunciada em homens (−74,5%), jovens de 15 a 24 anos (−78,0%) e moradores de áreas de exclusão social extrema (−79,3%). A redução ocorreu, sobretudo, nos homicídios cometidos com armas de fogo (−74,1%). O risco relativo de morte por homicídio nas áreas de exclusão extrema (tendo como referência áreas com algum grau de exclusão social) foi de 2,77 em 1996, 3,9 em 2001 e 2,13 em 2008. Nas áreas de alta exclusão social, o risco relativo foi de 2,07 em 1996 e 1,96 em 2008. Conclusões Para compreender a redução dos homicídios no Município, é importante considerar macrodeterminantes que atingem todo o Município e todos os subgrupos populacionais e microdeterminantes que atuam localmente, influenciando de forma diferenciada os homicídios com armas de fogo e os homicídios na população jovem, no sexo masculino e em residentes em áreas de alta exclusão social.

    The ELSA (Estudo Longitudinal de Saúde do Adulto - Brazilian Longitudinal Study for Adult Health) is a multicenter cohort study which aims at the identification of risk factors associated with type 2 diabetes and cardiovascular diseases in the Brazilian population. The paper describes the strategies for the collection, processing, transportation, and quality control of blood and urine tests in the ELSA. The study decided to centralize the tests at one single laboratory. The processing of the samples was performed at the local laboratories, reducing the weight of the material to be transported, and diminishing the costs of transportation to the central laboratory at the Universidade de São Paulo Hospital. The study included tests for the evaluation of diabetes, insulin resistance, dyslipidemia, electrolyte abnormalities, thyroid hormones, uric acid, hepatic enzyme abnormalities, inflammation, and total blood cell count. In addition, leukocyte DNA, urine, plasma and serum samples were stored. The central laboratory performed approximately 375,000 tests.

    Introducción: la hipertensión arterial y la diabetes mellitus tipo 2 tienden a coexistir en el mismo paciente. La hiperglucemia postprandial de dos horas es un predictor de enfermedad cardiovascular. Nuestro objetivo fue investigar la prevalencia de tolerancia a la glucosa alterada en sujetos hipertensos con glucosa de ayuno normal. Métodos: se incluyeron 65 pacientes hipertensos no diabéticos y con glucosa plasmática de ayuno < 100 mg/dL, en quienes se realizó una prueba de tolerancia a la glucosa. Resultados: encontramos tolerancia a la glucosa alterada en 32 pacientes (49.2 %), 29 en rango de intolerancia a la glucosa y tres casos en rango de diabetes mellitus. No hallamos relación entre glucosa postprandial con cifras de presión arterial ni con la edad, pero sí una correlación significativa entre intolerancia a la glucosa e índice de masa corporal > 32.6 (R = 0.59, p < 0.005, RR 4.2). Conclusión: nuestros resultados muestran que los pacientes hipertensos no diabéticos suelen cursar con tolerancia a la glucosa alterada, particularmente aquellos con índice de masa corporal aumentado, y que la glucosa de ayuno no es suficiente como prueba de monitoreo para diabetes mellitus tipo 2 en ese tipo de pacientes.

    Excavation of Toca do Serrote das Moendas, in Piauí state, Brazil revealed a great quantity of fossil wild fauna associated with human remains. In particular, fossils of a cervid (Blastocerus dichotomus) were found, an animal frequently pictured in ancient rock wall paintings. In a well-defined stratum, two loose teeth of this species were found in close proximity to human bones. The teeth were independently dated by electron spin resonance (ESR) in two laboratories. The ages obtained for the teeth were 29 ± 3 ka (thousands of years) and 24 ± 1 ka. The concretion layer capping this stratum was dated by optically stimulated luminescence (OSL) of the quartz grains to 21 ± 3 ka. As these values were derived independently in three different laboratories, using different methods and equipment, these results are compelling evidence of early habitation in this area.

    In the last decades, coagulase-negative staphylococci (CoNS), especially Staphylococcus epidermidis have become an important cause of bloodstream infections. In addition, rates of methicillin-resistance among CoNS have increased substantially, leading to the use of glicopeptides for therapy. The objective of this study was to evaluate eleven consecutives clinically relevant cases of oxacillin-resistant CoNS bacteremia in a general hospital localized in São Paulo city, Brazil. Five different species were identified by different phenotypic methods, including S. epidermidis (5), S. haemolyticus (3), S. hominis (1), S. warneri (1) and S. cohnii subsp urealyticus (1). A variety of Pulsed Field Gel Electrophoresis profiles was observed by macrorestriction DNA analysis in S. epidermidis isolates, but two of three S. haemolyticus isolates presented the same profile. These data indicated the heterogeneity of the CoNS isolates, suggesting that horizontal dissemination of these microorganisms in the investigated hospital was not frequent. One S. epidermidis and one S. haemolyticus isolates were resistant to teicoplanin and susceptible to vancomycin. The selective pressure due to the use of teicoplanin in this hospital is relevant.

    Background: Coffee is one of the most consumed beverages worldwide and the effect on cognition appears to be task specific and vary by age. Method: In cohort of 14,563 public service workers (35–74 years old) we assessed coffee consumption habits and examined cognitive function using standardized neuropsychological test battery. By linear regression and generalize linear regression with logarithmic link and gamma distribution we investigated the relation of coffee consumption (never/almost never, ≤1 cup/day, 2–3 cups/day, ≥3 cups/day) in the last 12 months to performance on specific domains of cognition for adults and elderly separately. Results: Among elderly, after adjustments, coffee consumption was associated only with an increase in the mean words remembered on learning, recall, and word recognition tests when comparing the 2–3 cups/day to never/almost never category (arithmetic mean ratio (AMR): 1.03; 95% Confidence Interval (CI): 1.00 to 1.07), and to an increase in the mean words pronounced in semantic verbal fluency test when comparing the ≥3 cups/day to never/almost never category (difference of the mean: 1.23; 95% CI: 0.16 to 2.29). However, coffee consumption was not associated with any cognitive function tests in adults and also was not associated with the phonemic verbal fluency test and trail-making test B in elderly. Conclusions: Results suggest that coffee consumption might be slightly beneficial to memory in elderly but lacks a dose response relationship. Longitudinal analyses are needed to investigate possible, even if subtle, positive effects of coffee drinking on specific cognitive domains in elderly. PMID:26610556

    Quality of life (QoL) is a subjective construct, which can be negatively associated with factors such as mental disorders and stressful life events (SLEs). This article seeks to identify the association between socioeconomic and demographic variables, common mental disorders, symptoms suggestive of depression and anxiety, SLEs with QoL in patients attended in Primary Care (PC). It is a transversal study, conducted with 1,466 patients attended in PC centers in the cities of São Paulo and Rio de Janeiro in 2009 and 2010. Bivariate analysis was performed using the T-test and four multiple linear regressions for each QoL domain. The scores for the physical, psychological, social relations and environment domains were, respectively, 64.7; 64.2; 68.5 and 49.1. By means of multivariate analysis, associations of the physical domain were found with health problems and discrimination; of the psychological domain with discrimination; of social relations with financial/structural problems; of external causes and health problems; and of the environment with financial/structural problems, external causes and discrimination. Mental health variables, health problems and financial/structural problems were the factors negatively associated with QoL.

    The Quadrilátero Ferrífero is a metallogenic district (Au, Fe, Mn) located at the southernmost end of the São Francisco craton in eastern Brazil. In this region, a supracrustal assemblage composed of Archean greenstone and overlying Neoarchean-Paleoproterozoic sedimentary rocks occur in elongated keels bordering domal bodies of Archean gneisses and granites. The tectonomagmatic evolution of the Quadrilàtero Ferrífero began in the Paleoarchean with the formation of continental crust between 3500 and 3200 Ma. Although this crust is today poorly preserved, its existence is attested to by the occurrence of detrital zircon crystals with Paleoarchean age in the supracrustal rocks. Most of the crystalline basement, which is composed of banded gneisses intruded by leucogranitic dikes and weakly foliated granites, formed during three major magmatic events: Rio das Velhas I (2920-2850 Ma), Rio das Velhas II (2800-2760 Ma) and Mamona (2760-2680 Ma). The Rio das Velhas II and Mamona events represent a subduction-collision cycle, probably marking the appearance of a modern-style plate tectonic regime in the Quadrilátero Ferrífero. Granitic rocks emplaced during the Rio das Velhas I and II events formed by mixing between a magma generated by partial melting of metamafic rocks with an end member derived by recycling gneissic rocks of older continental crust. After deformation and regional metamorphism at ca. 2770 Ma, a change in the composition of the granitic magmas occurred and large volumes of high-K granitoids were generated. The ca. 6000 m-thick Minas Supergroup tracks the opening and closure of a basin during the Neoarchean-Paleoproterozoic, between 2600 and 2000 Ma. The basal sequence involves continental to marine sediments deposited in a passive margin basin and contain as a marker bed the Lake Superior-type Cauê Banded Iron Formation. The overlying sediments of the Sabará Group mark the inversion of the basin during the Rhyacian Minas accretionary orogeny. This orogeny results from the collision between the nuclei of the present-day São Francisco and Congo cratons, generated the fold-and thrust belt structure of the Quadrilátero Ferrífero. Afterwards, the post- orogenic collapse resulted in the deposition of the Itacolomi Group and in the genesis of the dome-and-keel structure. In this paper, we review current knowledge about the 1500 Ma long-lasting tectonomagmatic and structural evolution of the Quadrilátero Ferrífero identifying the most compelling open questions and future challenges.

    In this study, we analyzed extreme precipitation indices, for present and future modeled climates over Northeast of Brazil (NEB), from CORDEX simulations over the domain of Tropical Americas. The period for the model validation was from 1989-2007, using data from the European Center (ECWMF) Reanalysis, ERA-INTERIM, as input to drive the regional model (RAMS 6.0). Reanalysis data were assimilated via both lateral boundaries and the entire domain (a much weaker "central nudging"). Six indices of extreme precipitation were calculated over NEB: the average number of days above 10, 20 and 30 mm in one year (R10, R20, R30), the number of consecutive dry days (CDD), the number of consecutive wet days (CWD) and the maximum rainfall in five consecutive days (RX5). Those indices were compared against two independent databases: MERRA (Modern Era Retrospective analysis for Research and Applications) and TRMM (Tropical Rainfall Measuring Mission). After validation, climate simulations were performed for the present climate (1985-2005) and short-term (2015-2035), mid-term (2045-2065) and long-term (2079 to 2099) future climates for two scenarios: RCP 4.5 and RCP 8.5, nesting RAMS into HadGEM2-ES global model (a participant of CMIP5). Along with the indices, we also calculated Probability Distribution Functions (PDFs) to study the behavior of daily precipitation in the present and by the end of the 21st century (2079 to 2099) to assess possible changes under RCPs 4.5 and 8.5. The regional model is capable of representing relatively well the extreme precipitation indices for current climate, but there is some difficulties in performing a proper validation since the observed databases disagree significantly. Future projections show significant changes in most extreme indices. Rnn generally tend to increase, especially under RCP8.5. More significant changes are projected for the long-term period, under RCP8.5, which shows a pronounced R30 enhancement over northern states. CDD tends to decrease over most of NEB in the short but this trend is reverted toward the end of the century in both scenarios with a significant increase in the duration of the dry season over Northwestern and Eastern NEB (exceeding 50 days over certain areas), whereas projected CWD changes are smaller. Rx5 shows a general increasing trend especially in the long term period,under RCP8.5.

  20. Impact of vinasse application in the C and N in the soils cultivaded with sugarcane in South Brasil, using Isotopic Technique

    The main anthropogenic sources in the environment are fertilizers, pesticides, biomass burning, vehicle emissions, and disposal of urban and industrial waste. Vinasse is characterized as a residual of sugarcane distillery effluent with high concentrations of potassium and organic matter. The environmental impact caused by its use in the vinasse is modification chemical and physical properties in the soil and water. For this, the isotopic technique can be a powerful tool to understand the biogeochemical cycling of light elements (C and N). Some environmental studies have been conducted involving isotopic characterization of Carbon and Nitrogen in soil. Several soils cultivated with sugarcane of different regions of São Paulo state, Brazil, were analyzed to perform the isotopic characterization. The study area was selected where soil management is by mechanical harvesting of sugarcane and vinasse application. The area was divided into three parts: control (without cultivation); after mechanical harvesting of sugarcane; after mechanical harvesting of sugarcane and vinasse application. Three days after the harvest of sugarcane the vinasse was applied and sampling of soil surface was carried out in two periods of 7 and 30 days after application of vinasse. The isotopic determination in the sample soil and concentration of C and N was by IRMS, Thermo Delta Plus, allowing simultaneous determination of 13C/12C isotope ratios (δ13C) and 15N/14N (δ15N). The results of the C and N concentration in the vinasse applied were average values 2.52% and 0.02% and isotopic values of 13C and 15N were -14.1‰ and 5.2‰. The results for the C concentration of the three areas in two periods showed values around 0.86 to 1.01%. The 13C isotopic values were -16.8 to -15.0‰, demonstrating the predominant cultivation in the region in relation to δ13C values of C4 plant (sugarcane). The results of N analysis were 0.08 to 0.10% and 15N isotope analysis, showing values ranging from 7.9 to 8.5‰. No significant variation in concentration of N and C in three study areas was observed. Considering 13C and 15N isotopic characterization independent of management, there was noted no isotopic fractionation by microbial activity. The results evidenced that the addition of vinasse in the soil did not increase the concentration of C and N does not represent a source of C and N. Furthermore, the isotopic technique can be applied in studies involving biogeochemical cycling, aiming to identify progress or setbacks in the quality of soil and possible impact in ecosystem.

  2. Magnetic fabric and emplacement mechanisms in a co-mingled mafic and felsic magma chamber: the Espinharas granite (Borborema Province, NE Brasil)

    The Espinharas granite is a co-mingled mafic and felsic magmatic complex forming part of the widespread Brasiliano plutonism that affected the Borborema Province during the Neoproterozoic. Syenogranite is mixed and mingled with diorite generating a range of aluminous shoshonitic hybrid rocks containing mafic microgranular enclaves (MME) of various shapes and orientations. Geochemical modelling shows that the pluton originated by upper-mantle magma underplating and fault-assisted intrusion of diorite, which would supply heat for partial melting of the crust and formation of syenogranite. The Espinharas granite comprises syenogranites and diorites associated with quartz-monzonites, monzodiorites and syenites mainly deformed in the magmatic state. The pluton is emplaced within Paleoproterozoic augen gneisses from the basement and is bounded by high-temperature NE-trending mylonitic shear zones at its western and eastern borders. To the south, the pluton is in contact with the E-trending high-grade transpressional Patos shear zone. Magmatic foliations can be observed throughout the syenogranite and in the felsic rocks, being defined by a SPO of feldspars and quartz. However, they appear to be absent in the diorite. The microgranular enclaves display irregular contacts with the host syenogranite and may be often aligned in agreement with the magmatic foliation; they are also randomly dispersed and disrupted by monzo- to syenogranitic veins. The Anisotropy of Magnetic Susceptibility (AMS) technique was employed in order to investigate the mechanical relationships between mingled mafic and felsic magmas, as well as their emplacement mechanisms. Susceptibilities are usually high (k > 1.3 mSI), suggesting that Ti-magnetite is the main carrier of the magnetic signal. The magnetic lineation plunges shallowly to NE, parallel to the pluton main elongation axis. Zircons from diorite and syenogranite yield U-Pb (SHRIMP) ages of ~ 620 Ma, which are attributed to the crystallization of the granite and are younger than the main metamorphic event in the Seridó Belt (~ 575 Ma). These data suggest that the magnetic fabric of the Espinharas granite records the high-temperature deformation observed in the Seridó Belt. This deformation was active during a prolonged time range (~ 100 Ma) in a hybrid magmatic chamber emplaced in the middle- to shallow continental crust. These conditions indicate that the Patos shear zone controlled the development of the magmatic- to solid-state fabric of the Espinharas granite, highlighting the contribution of strain partitioning in the mechanical mingling of magmas in the continental crust.

Most of the crystalline basement, which is composed of banded gneisses intruded by leucogranitic dikes and weakly foliated granites, formed during three major magmatic events: Rio das Velhas I (2920-2850 Ma), Rio das Velhas II (2800-2760 Ma) and Mamona (2760-2680 Ma). The Rio das Velhas II and Mamona events represent a subduction-collision cycle, probably marking the appearance of a modern-style plate tectonic regime in the Quadrilátero Ferrífero. Granitic rocks emplaced during the Rio das Velhas I and II events formed by mixing between a magma generated by partial melting of metamafic rocks with an end member derived by recycling gneissic rocks of older continental crust. After deformation and regional metamorphism at ca. 2770 Ma, a change in the composition of the granitic magmas occurred and large volumes of high-K granitoids were generated. The ca. 6000 m-thick Minas Supergroup tracks the opening and closure of a basin during the Neoarchean-Paleoproterozoic, between 2600 and 2000 Ma. The basal sequence involves continental to marine sediments deposited in a passive margin basin and contain as a marker bed the Lake Superior-type Cauê Banded Iron Formation. The overlying sediments of the Sabará Group mark the inversion of the basin during the Rhyacian Minas accretionary orogeny. This orogeny results from the collision between the nuclei of the present-day São Francisco and Congo cratons, generated the fold-and thrust belt structure of the Quadrilátero Ferrífero. Afterwards, the post- orogenic collapse resulted in the deposition of the Itacolomi Group and in the genesis of the dome-and-keel structure. In this paper, we review current knowledge about the 1500 Ma long-lasting tectonomagmatic and structural evolution of the Quadrilátero Ferrífero identifying the most compelling open questions and future challenges.

    Soil-transmitted helminth (STH) infections represent a major public health problem in poor and developing countries. During the period September-October 1998 we conducted an epidemiological survey of STH infections in schoolchildren of an urban area (group A) and an indigenous reserve (group B), in the Municipality of Ortigueira, State of Paranà, Brazil, to assess potential benefits of mass treatment. Stool samples were examined for helminth eggs by quantitative (Kato-Katz) technique to determine the prevalence and intensity of intestinal parasitic infection. Moreover, we examined the relationship between prevalence and intensity of STH infections and housing/hygienic factors (by means of a 7-item questionnaire). 236 schoolchildren aged 5-15 years were enrolled, 136 in group A and 100 in group B. The prevalence of STH infections was significantly higher in group B (93%) than in group A (22%) (P < 0.001). Detected parasites were: A. lumbricoides (16.1% prevalence in group A, 88% in group B, P < 0.001), hookworms (5.8% in group A, 52% in group B, P < 0.001) and T. trichiura (5.1% in group A, 2% in group B, P = 0.2). Heavy infections were detected in 2.9% and 23% of the children in group A and B, respectively (P < 0.001). Housing/hygienic indicators were significantly poorer in group B. A statistically significant correlation was observed between total prevalence of STH infections and prevalence of high-intensity infections with most housing/hygienic variables. On the basis of these results, mass treatment and educational interventions were suggested for the indigenous community, whereas target treatment and educational interventions were suggested for the urban community. Even in a geographically homogeneous area different epidemiological realities can be found, which in turn can influence infection levels and control programmes. PMID:10810031

    The main goal of this paper is to estimate a set of optimal seasonal, daily, and hourly values of atmospheric turbidity and surface radiative parameters Ångström's turbidity coefficient ( β), Ångström's wavelength exponent ( α), aerosol single scattering albedo ( ω o ), forward scatterance ( F c ) and average surface albedo ( ρ g ), using the Brute Force multidimensional minimization method to minimize the difference between measured and simulated solar irradiance components, expressed as cost functions. In order to simulate the components of short-wave solar irradiance (direct, diffuse and global) for clear sky conditions, incidents on a horizontal surface in the Metropolitan Area of Rio de Janeiro (MARJ), Brazil (22° 51' 27″ S, 43° 13' 58″ W), we use two parameterized broadband solar irradiance models, called CPCR2 and Iqbal C, based on synoptic information. The meteorological variables such as precipitable water ( u w ) and ozone concentration ( u o ) required by the broadband solar models were obtained from moderate-resolution imaging spectroradiometer (MODIS) sensor on Terra and Aqua NASA platforms. For the implementation and validation processes, we use global and diffuse solar irradiance data measured by the radiometric platform of LabMiM, located in the north area of the MARJ. The data were measured between the years 2010 and 2012 at 1-min intervals. The performance of solar irradiance models using optimal parameters was evaluated with several quantitative statistical indicators and a subset of measured solar irradiance data. Some daily results for Ångström's wavelength exponent α were compared with Ångström's parameter (440-870 nm) values obtained by aerosol robotic network (AERONET) for 11 days, showing an acceptable level of agreement. Results for Ångström's turbidity coefficient β, associated with the amount of aerosols in the atmosphere, show a seasonal pattern according with increased precipitation during summer months (December-February) in the MARJ.

    Introdução: O processo de envelhecimento provoca modificações estruturais e funcionais à saude, comprometendo o controle postural e processamento central. Estudos têm abordado a necessidade de identificar os fatores de risco prejudiciais à saúde auditiva e segurança em idosos acometidos por déficits auditivos e com alterações de equilíbrio.Objetivo: Avaliar o efeito da prótese auditiva na qualidade de vida, no equilíbrio e no medo de queda em idosos com perda auditiva bilateral.Método: Estudo clínico e experimental realizado com 56 idosos com perda auditiva neurossensorial, submetidos ao uso da prótese auditiva de amplificação sonora individual (AASI). Os idosos responderam aos questionários de qualidade de vida Short Form Health Survery (SF-36), Falls Efficacy Scale- Internacional (FES-I) e o teste de Berg Balance Scale (BBS). Após 4 meses, os idosos que adaptaram ao uso da AASI foram reavaliados.Resultados: Houve 50% de adaptação dos idosos ao AASI. Foi observado que o sexo masculino teve maior dificuldade em adaptar ao aparelho auditivo e que as variáveis idade, grau de perda, presença de zumbido e vertigem não interferiram na adaptação à prótese auditiva. Houve melhora da qualidade de vida nos domínios Estado da Saúde Geral (EGS) e Capacidade Funcional (CF) e do zumbido, assim como o aumento da auto-confiança após adaptação da prótese auditiva.Conclusão: O uso de prótese auditiva propiciou a melhora dos domínios da qualidade de vida, o que refletiu em uma melhor auto-confiança e consequentemente a longo prazo na redução do medo de queda em idosos com perda auditiva neurossensorial.

    OBJECTIVE To understand the job function of caregivers of older adults and contribute to the debate on the consolidation of this professional practice. METHODOLOGICAL PROCEDURES This is a descriptive, qualitative, and exploratory study. Four focal group sessions were performed in 2011 with 11 elderly companions, formal caregivers of older adults in the Programa Acompanhante de Idosos (Program for Caregivers of Older Adults), Sao Paulo, SP, Southeastern Brazil. These sessions, guided by a semi-structured script, were audio-recorded and fully transcribed. Data were analyzed using the Content Analysis technique, Thematic Modality. RESULTS In view of considering the caregivers of older adults as a new category of workers, it was difficult to define their duties. The elderly companions themselves as well as the care receivers, their families, and the professionals that comprised the team were unclear about their duties. The professional practice of these formal caregivers has been built on the basis of constant discussions and negotiations among them and other team members in Programa Acompanhante de Idosos during daily work. This was achieved via a recognition process of their job functions and by setting apart other workers’ exclusive responsibilities. CONCLUSIONS The delimitation of specific job functions for elderly companions is currently one of the greatest challenges faced by these workers to develop and consolidate their professional role as well as improve Programa Acompanhante de Idosos.

    Background Population antimicrobial use may influence resistance emergence. Resistance is an ecological phenomenon due to potential transmissibility. We investigated spatial and temporal patterns of ciprofloxacin (CIP) population consumption related to E. coli resistance emergence and dissemination in a major Brazilian city. A total of 4,372 urinary tract infection E. coli cases, with 723 CIP resistant, were identified in 2002 from two outpatient centres. Cases were address geocoded in a digital map. Raw CIP consumption data was transformed into usage density in DDDs by CIP selling points influence zones determination. A stochastic model coupled with a Geographical Information System was applied for relating resistance and usage density and for detecting city areas of high/low resistance risk. Results E. coli CIP resistant cluster emergence was detected and significantly related to usage density at a level of 5 to 9 CIP DDDs. There were clustered hot-spots and a significant global spatial variation in the residual resistance risk after allowing for usage density. Conclusions There were clustered hot-spots and a significant global spatial variation in the residual resistance risk after allowing for usage density. The usage density of 5-9 CIP DDDs per 1,000 inhabitants within the same influence zone was the resistance triggering level. This level led to E. coli resistance clustering, proving that individual resistance emergence and dissemination was affected by antimicrobial population consumption. PMID:21356088

    Huanglongbing (HLB), an insect-transmitted disease of citrus, known for many years in Asia and Africa, has appeared in the state of São Paulo State (SSP), Brazil, in 2004, and the state of Florida, USA, in 2005. HLB endangers the very existence of citrus, as trees infected with the bacterial pathogen, irrevocably decline. In the absence of curative procedures, control of HLB is difficult and only based on prevention. Even though not available in culture, the HLB bacterium could be shown to be Gram-negative and to represent a new candidate genus, Candidatus Liberibacter, in the alpha subdivision of the Proteobacteria. Three Candidatus (Ca.) L. species occur: Ca. L. africanus in Africa, Ca. L. asiaticus in Asia, SSP, and Florida, and Ca. L. americanus in SSP. The liberibacters occur exclusively in the phloem sieve tubes. On affected trees, HLB symptoms are often seen on certain branches only, suggesting an uneven distribution of the Liberibacter. Occurrence of Ca. L. americanus, the major HLB agent in SSP, has been examined in 822 leaf samples from an affected sweet orange tree by two conventional PCR techniques and a newly developed real time (RTi) PCR, also used for quantification of the Liberibacter in the leaves. Even though RTi-PCR was able to detect as few as 10 liberibacters per gram of leaf tissue (l/g), no liberibacters could be detected in any of the many leaf samples from a symptomless branch, while in blotchy mottle leaves from symptomatic branches of the same tree, the Liberibacter titer reached values as high as 10(7)l/g. These results demonstrate the uneven distribution of the Liberibacter in HLB-affected trees.

    Introducción: El Ácido -Lipóico (ALA) ha sido utilizado como recurso terapéutico para reducir daño oxidativo en la Hipertensión Arterial Sistémica (HAS), pero aún no existen estudios in vivo que reporten sobre su mecanismo de acción en el metabolismo del hierro. Objetivo: Evaluar el efecto antioxidante del ácido Alfa- Lipóico sobre el hemograma y metabolismo del hierro en individuos hipertensos con o sin anemia. Métodos: Estudio clínico doble-ciego, randomizado y controlado con placebo. La muestra fue constituida por 60 individuos hipertensos, distribuidos aleatoriamente en grupo tratamiento (n = 32), que recibió 600 mg/día del ALA por doce semanas y grupo control (n = 28), que recibió el placebo por el mismo período. Fueron analizados antes y después de la intervención, los parámetros del hemograma, Hierro Sérico, Ferritina, Capacidad Latente de Enlace del hierro, Capacidad Total de Enlace del Hierro, Índice de Saturación de la Transferrina (ISI) y Transferrina. Para evaluar las alteraciones entre los grupos, se utilizó el teste t de Student y el análisis de varianza ANOVA, adoptándose el nivel de significación de 5%. Resultados: Después de la intervención, el suplemento con el ALA demostró una asociación estadísticamente significativa (p < 0,05) con la reducción de los leucocitos totales, aumento del número de neutrófilos y reducciones en los niveles de Hierro Sérico e ISI. Conclusión: La administración oral del ALA como un adyuvante terapéutico, altera la respuesta hematológica del leucograma y reduce la absorción del hierro. Cabe senãlar que el mecanismo de quelación de metales por el ácido lipoico puede ser responsable de estos cambios y, en consecuencia, podría desencadenar una condicion de anemia ferropénica en individuos hipertensos.

    Introdução: Perdas de peso melhoram o controlo da tensão arterial em indivíduos hipertensos. As intervenções comportamentais para a perda de peso parecem ser menos eficazes nos imigrantes de origem africana (IOA). Os principais objetivos foram avaliar os efeitos no peso de uma intervenção alimentar em hipertensos nativos de origem portugueses (NOP) e IOA; identificar fatores de sucesso na perda de peso; avaliar a evolução dos conhecimentos e adesão às recomendações alimentares. Material e Métodos: Foram selecionados aleatoriamente hipertensos medicados seguidos nos cuidados de saúde primários para um estudo de duas fases, observacional (15 meses) e de intervenção comportamental (seis meses). Os participantes foram divididos em dois grupos: IOA e NOP. Foram dadas recomendações alimentares e de estilos de vida em sessões individuais presenciais e telefónicas. Resultados: Dos 110 participantes, com IMC médio de 31,6 ± 3,7 kg/m2 e idade média 61,3 ± 10,0 anos, 60 eram imigrantes. Durante a intervenção os NOP perderam 1,4 ± 2,7% do peso e os IOA 0,8 ± 3,6%, sendo a perda superior comparativamente com a fase observacional. Ser do sexo masculino e consumir pelo menos duas porções de lacticínios magros por dia associou-se a maior perda de peso durante a intervenção, independentemente da idade e origem. Houve um aumento significativo no número de recomendações dietéticas conhecidas e cumpridas, com os NOP a cumprirem em média mais recomendações. Discussão: A intervenção foi bem sucedida relativamente à perda de peso, especialmente no grupo dos NOP, confirmando outros estudos. Conclusão: A intervenção aumentou os conhecimentos e adesão às recomendações, realçando a pertinência da educação alimentar, culturalmente adaptada, nos cuidados de saúde primários.

    El incremento matutino de la presión arterial (IMPA) aumenta el riesgo cardiovascular. Los estudios que evalúan la asociación entre IMPA domiciliaria y daño de órgano blanco son escasos y casi exclusivamente basados en población asiática. Nuestro objetivo fue caracterizar a los pacientes hipertensos con IMPA domiciliaria y establecer una posible asociación con la presencia de hipertrofia ventricular izquierda (HVI). Métodos: se incluyeron hipertensos medicados ≥18 años que realizaron mediciones de PA domiciliaria (4 días de mediciones por duplicado, a la mañana, tarde y noche) y completaron un cuestionario acerca de sus factores de riesgo y antecedentes de enfermedad cardiovascular. Se revisaron las historias clínicas para extraer datos ecocardiográficos. Se definió como IMPA a una diferencia entre el promedio de PA sistólica domiciliaria matutina – vespertina ≥15 mmHg. Se consideró que los pacientes tenían HVI si el índice de masa ventricular era >95 g/m2 en mujeres y >115 g/m2 en varones. Las variables identificadas como predictores relevantes de IMPA fueron introducidos en un modelo multivariado de regresión logística. Resultados: se incluyeron 216 pacientes, con una edad media de 68 (+13,3) años, 69,4% mujeres y 99,1% caucásicos. La prevalencia de IMPA fue de 13,4% y las variables independientemente asociadas fueron HVI (OR 3,5; 95%CI 1,1-11,4), edad (OR 1,05; 95%CI 1,003-1,1) y antecedente de enfermedad cerebrovascular (OR 3,9; 95%CI 1,1-14,2). En conclusión, el IMPA evaluado por monitoreo domiciliario presenta asociación independiente con HVI, edad y antecedentes de enfermedad cerebrovascular, debiendo esclarecerse las implicancias terapéuticas de esta observación en estudios prospectivos a gran escala.

    Objetivo: evaluar el posible efecto hipotensor en sujetos pre-hipertensos e hipertensos, de un extracto de hoja de olivo (EHO) estandarizado al 15% (m/m) en oleoeuropeína y con un contenido medio del 10% (m/m) en ácidos triterpénicos y del 1% (m/m) en hidroxitirosol. Asimismo, se ha valorado su acción sobre el estatus antioxidante y el perfil lipídico sanguíneos. Material y métodos: se ha llevado a cabo un ensayo de intervención en humanos con administración de 1.600 mg de extracto/día. Los parámetros evaluados han sido presión sistólica y diastólica, retardo de la oxidación del colesterol LDL (lag time) y niveles sanguíneos de óxido nítrico (NO), malondialdehído (MDA), capacidad antioxidante (CAO), perfil lipídico, glucosa, transaminasas y creatinina. Resultados: se observó en todos los sujetos una disminución estadísticamente significativa de la presión sistólica y diastólica, y un aumento de los niveles de NO (P < 0,050). En los sujetos con presión sistólica más elevada también se redujo significativamente su valor tras la intervención (P = 0,002). El “lag time” de las LDL aumentó significativamente (P = 0,047), y en todos los sujetos los niveles de colesterol (CHO) se redujeron significativamente. Los niveles de colesterol LDL, triglicéridos (TG) y del índice CHO/colesterol HDL disminuyeron con tendencia a la significancia (P = 0,076; P = 0,059; P = 0,056; respectivamente). Conclusión: este estudio, aunque preliminar, pone de relieve por primera vez la influencia positiva del EHO ensayado en la regulación de la hipertensión así como en la velocidad de oxidación de las LDL y en el perfil lipídico sanguíneo.

    Antecedentes: una de las características relevantes de las drogas antihipertensivas es que su acción cubra 24 hs. Administrar una sola dosis diaria aumenta la adherencia al tratamiento, y redunda en mejorar el impacto sobre morbimortalidad, principal objetivo de todo tratamiento antihipertensivo. El MAPA permite valorar la duración del efecto. Losartán es un antagonista de receptores At1 de AII, de comprobada eficacia. Distintos estudios sugieren una cobertura antihipertensiva menor de 24 hs. La aparición de una nueva forma farmacéutica (Cronos) que libera 50 mg en forma regular y otros 50 mg en forma prolongada favorece una cobertura de 50 mg durante 24 hs. Objetivo: 1) Evaluar la eficacia de Losartán Cronos, en el control de 24 horas de la TA en hipertensos esenciales, utilizando MAPA. 2) Analizar tasa de respuesta ambulatoria, homogeneidad del efecto y rigidez arterial ambulatoria (AASI). Material y métodos: fueron incluidos 142 hipertensos esenciales de ambos sexos; Se trataron 105 pacientes con Losartán Cronos en monodosis matinal durante 8 semanas, momento del segundo MAPA. 97 pacientes con MAPAs válidos fueron evaluados. Resultados: se observó un descenso significativo tanto de TAS como TAD en todos los periodos evaluados: 24 hs, día, noche, y las últimas 4 hs interdosis. No hubo cambios significativos en la frecuencia cardíaca 24 hs. El ascenso matinal de la TA (mmHg/hora) descendió de 4.53 a 3,68 (p=0.03). La relación Valle:Pico fue 0.91 para TAS y 1.14 para TAD. El Índice de Alisado fue 2.86 para TAS y 3.17 para TAD. 19 pacientes tuvieron EA, todos fueron leves. Conclusión: Losartán Cronos mostró eficacia y seguridad. Desciende la TA sin efectos significativos sobre la FC, reduce la PP, y su efecto perdura 24 hs evaluado por relación Valle:Pico, por efecto de las ultimas 4 hs interdosis, y por descenso de la velocidad de ascenso matinal tensional, por lo que sugiere su administración en monodosis diaria.

    The Efectividad de un Programa de Intervención en el Control de la Presión Arterial de los Hipertensos en Riesgo de Desarrollar Insuficiencia Cardiaca (HEROIC) study was designed to assess whether an educational program for primary care physicians could improve blood pressure (BP) control in hypertensive patients at high risk for developing heart failure. The program contained a combination of educational training (live group sessions or online training) and information feedback. Two hundred twenty-six physicians completed the program and provided valid data in 2489 patients before and 2168 after 1 year. There was a small but significant reduction of -1.1 mm Hg (P=.009) in systolic BP and a higher proportion of patients achieved their BP target (13.6% vs 15.6%, P=.055). Thus, the authors concluded that there was a slight improvement in BP control after the educational program, but this change was not sufficient to avoid development of heart failure. More complex and intensive programs are needed for this type of prevention.

    Aphids are among the major pests associated with strawberries in Southern Brasil. In this study, we identified the main species that occur in strawberry fields in the states of Paraná and Rio Grande do Sul, Brasil. We also compared the effectiveness of different sampling methods and studied the population dynamics of aphid species during two strawberry crop cycles in the municipality of Pinhais, state of Paraná, Brasil. Chaetosiphon fragaefolii (Cockerell) and Aphis forbesi Weed were the main species associated with strawberry. The method of hit plant and the Möericke trap showed equal effectiveness to capture wingless and winged insects. The peak population of aphids in the state of Paraná occurred from September to November. This information can help producers to implement strategies to monitor and control the major aphid species that occur in strawberry culture. PMID:27193281

    Knowing the users is capital for building user-friendly digital interfaces. One way to think about the users is considering their familiarity with this technology. This article presents the results of twelve interviews with elderly people residing in the so-called South Zone of Rio de Janeiro (Brazil) who have used mobile phones over at least one year. It is part of the Doctor's Thesis "Mobile phones for elderly people - usability for social integration" ("Celulares para idosos - usabilidade a serviço da integração social"), which is targeted at ascertaining if the current mobile phones are user-friendly for elderly people. Through the technique of Guided Interviews, we found usage time, criteria for choice of phones, reasons for changes, preferences, and manners of use. Preliminarily, we have noticed differences in the behavior of the participating users and performed a qualitative analysis according to groups of age and gender.

    Introdução: A preocupação com a segurança na saúde torna essencial que todos os utentes, em particular os idosos por serem maioritariamente polimedicados, possuam uma lista completa e atualizada da sua medicação. Assim, propusemo-nos avaliar a qualidade dos registos eletrónicos de medicação prolongada.Material e Métodos: Estudo observacional, transversal e descritivo, com componente analítico, no qual avaliámos a qualidade técnica dos registos de medicação prolongada nos idosos de quatro unidades de cuidados de saúde primários da região norte, antes e após uma intervenção. Nesta, efetuámos formação de boas práticas de registo aos médicos e promovemos a utilização do guia de Medicação Prolongada aos profissionais e utentes.Resultados: Avaliámos 388 registos de 33 médicos. A categoria ideal, ‘Medicação apropriada e posologia presente’, aumentou de 23,5% para 48% (p < 0,001). As restantes categorias ‘Medicação inapropriada’ e ‘Medicação apropriada e posologia ausente’ diminuíram de 16,7% para 7% (p = 0,006) e de 59,8% para 46,0% (p = 0,02), respetivamente. As variáveis condição de orientador de formação, local de trabalho, anos de Medicina Geral e Familiar e percentagem de idosos, apresentaram diferenças com significado estatístico no início do estudo, no entanto após a ‘intervenção’, apenas a percentagem de idosos continuou a apresentá-las.Discussão: Neste estudo, os médicos aderiram à proposta de mudança, independentemente da idade, género, condição de orientador de formação, local de trabalho e anos de Medicina Geral e Familiar. Consultas mais prolongadas na população idosa poderão ter impedido alcançar a melhor categoria de registo.Conclusão: Este trabalho original mostra que é necessário implementar medidas periódicas de formação pós-graduada para manutenção de registos médicos atualizados.

    Introducción: El Dietary Sodium Restriction Questionnaire (DSRQ) evalúa actitudes y comportamientos de pacientes con insuficiencia cardiaca (IC) relacionados con el cumplimiento de la restricción de sodio. Recientemente, ha sido traducido y adaptado culturalmente para uso en Brasil. No obstante, una validación adicional del instrumento se requiere para que pueda ser utilizado en el manejo de pacientes con IC en Brasil. Objetivo: Probar la fiabilidad y validez de la versión brasileña del DSRQ. Métodos: Validez aparente y de contenido fueron evaluados por un grupo de especialistas. Validez de constructo se evaluó mediante análisis factorial exploratoria y confirmatoria. La fiabilidad y consistencia interna del cuestionario fue evaluada mediante el coeficiente alfa de Cronbach. Resultados: Un total de 206 pacientes ambulatorios con IC fueron evaluados (edad media, 60,4 ± 11,9 años). Los resultados de la validez aparente y de contenido demostró la equivalencia entre la versión brasileña y de la versión original. En el análisis factorial exploratorio, el análisis de componentes principales (PCA) se obtuvieron cuatro factores con valores superiores a 1. Tres modelos fueron probados en el análisis factorial confirmatoria, y el modelo de tres factores resultantes del PCA mostró el mejor ajuste, representando 49% de la varianza. El alfa obtenido para las escalas de actitud/norma subjetiva, control de la conducta percibido y comportamiento dependiente fueron 0,71, 0,67 y 0,79, respectivamente. Conclusiones: Nuestros resultados sugieren que la versión brasileña del DSRQ es un instrumento válido y fiable para medir las actitudes y comportamientos relacionados con una dieta baja en sodio en pacientes brasileños con IC.

    The cave of Toca do Serrote do Artur (São Raimundo Nonato Archaeological Area, southeastern Piauí, Brazil) has yielded a Mammalian community constituted of Dasypus septemcinctus, Propraopus cf. sulcatus, Hoplophorus euphractus, Glyptodon clavipes, Conepatus sp., Panthera onca, Equus neogaeus, Dicotyles tajacu, Tayassu pecari, Palaeolama major, Mazama guazoubira, Mazama americana and a large Cervid. In comparison with the Mammalian fauna of the other sites from the same area, such a list shows a comparatively reduced biodiversity together with the presence of rare ( Hoplophorus, Conepatus) or unknown ( Propraopus, Palaeolama major) taxa. Explanation lies in the more recent age of the fossiliferous layers, probably Lower Holocene, as demonstrated by two 14C dating of 8 490 ± 120 BP and 6 890 ± 60 BP of the highest one. Moreover, that fauna shows the late survival of some genera ( Propraopus, Hoplophorus, Glyptodon, Equus, Palaeolama) together with climatic modifications related to the Pleistocene-Holocene transition.

    Además de importante marcador de las reservas de hierro, la ferritina sérica es un marcador de la inflamación sistémica, mientras que la obesidad se ha asociado con la inflamación crónica. Objetivo: Identificar, después de 6 meses, el efecto de la cirugía bariátrica sobre los niveles de ferritina sérica en hipertensos, diabéticos o sin estas comorbilidades preoperatorias mujeres. Pacientes y métodos: Los autores realizaron un estudio retrospectivo de 200 mujeres sometidas a bypass gástrico en Y de Roux (BGYR), con edades comprendidas entre 20 y 45 años, con un índice de masa corporal (IMC) superior a 35 kg/m2, con hipertensión arterial (HA, n = 70), la diabetes mellitus tipo 2 (DM2, n = 40) y sin comorbilidades (SC, n = 90) fueron evaluados antes y 6 meses después de BGYR. Antropométricas, de laboratorio (ferritina sérica y hemoglobina) y la información de comorbilidad se recogió de la historia clínica electrónica. Resultados: Antes de la cirugía, las mujeres con comorbilidades eran mayores, tenían mayores hipertensos IMC, niveles más altos de ferritina diabéticos en relación con el grupo SC. La resolución de las comorbilidades después de 6 meses de DGYR ocurrió en el 68 % de las mujeres con hipertensión y el 86 % de los diabéticos. 6 meses después de la cirugía, se observó una disminución de la ferritina sérica en mujeres con comorbilidades de 110,1 ± 86,3 a 88,7 ± 80,5 ng/dl en el grupo con hipertensión y 164,8 ± 133,4 a 101 2 ± 97,7 ng/dl en DM2 (p < 0,05) y la hemoglobina, excepto en los pacientes diabéticos (p > 0,05). Conclusión: El aumento de la ferritina en mujeres obesas en el periodo de premenopausia se relacionan con las principales comorbilidades de la obesidad, y la presencia de estas comorbilidades fue fundamental en la reducción de la ferritina sérica después de la cirugía bariátrica.

    Introdução: Próteses auditivas destacam-se em função das tecnologias que as tornam cada vez menores, mais potentes e eficientes. O marketing pode gerar expectativas irreais quanto aos resultados com o uso de amplificação, principalmente em indivíduos inexperientes.Objetivo: Verificar a relação entre expectativas e sucesso do processo de seleção e adaptação de próteses auditivas em idosos.Método: Estudo clínico e experimental, 16 indivíduos idosos, inexperientes com o uso de amplificação, foram avaliados 15 dias antes e após a seleção e adaptação de próteses auditivas. Utilizou-se “Questionário para avaliação das expectativas do indivíduo adulto/idoso, novo usuário de próteses auditivas”, Hearing Handicap Inventory for the Elderly/Screening Version, para avaliação da percepção da restrição de participação e o Questionário Internacional - Aparelho de Amplificação Sonora Individual (QI-AASI), para verificar o benefício subjetivo com o uso das próteses auditivas. Determinou-se o Índice Percentual de Reconhecimento de Sentenças no Silêncio (IPRSS), por meio do teste Listas de Sentenças em Português para verificar o benefício objetivo da adaptação. Os dados foram analisados por meio de teste não-paramétrico, com nível de significância de 5%.Resultados: Toda a amostra apresentou expectativas positivas. Subjetivamente verificou-se benefício pela diminuição da percepção da restrição de participação e pela avaliação positiva da adaptação, evidenciada pelo QI-AASI. Objetivamente a melhora do IPRSS com o uso de próteses auditivas também evidenciou beneficio.Conclusão: a expectativa quanto aos resultados com o uso de amplificação, foi fator de influência negativa no sucesso do processo de seleção e adaptação de próteses auditivas, no âmbito subjetivo.

    The scope of this article is to analyze the scientific evidence addressing the factors that influence the sexuality of the elderly. It involved an online search carried out in pairs, including original articles published between 2006 and October 2011 in Portuguese, English or Spanish, which fulfilled the requirements of the study. The MEDLINE, LILACS, CidSaúde and BDENF databases were used with the key words: sexualidade e idoso / sexuality and elderly / sexualidad y anciano. The articles selected were assessed for methodological quality using two instruments, namely CASP and the Hierarchical Classification of Evidence. After analysis, 15 articles were included in the review, which discuss the culture of asexuality of the elderly, whereby the experience of sexuality only prevails among younger people. The absence of the partner due to widowhood, attributing value to beauty standards of the young, the occurrence of disease, use of medication, and changes in sexual physiology were identified as important factors that influence the sexuality of the elderly. The conclusion drawn is that social and cultural factors, changes in body physiology, and the occurrence of disease interfere with the sexuality of the elderly, making it necessary for nursing professionals to be proactive in debunking myths and providing orientation.

    This paper is an integrative review analyzing the scientific production and legal documents regarding public policies for the elderly in Brazil. Research was conducted in the Virtual Health Library and Scopus databases, examining publications since 2003. Data were collected from June to September of 2011 using the following key words: "elderly" (idosos), "public policies" (políticas públicas), "elderly person" (pessoa idosa), "aging" (envelhecimento) and "civic participation" (participação cidadã). The search resulted in the selection of 15 articles and six legal documents targeted at the elderly in Brazil that were submitted to content analysis by categorization. The results revealed that aging in Brazil has occurred in the midst of adaptations entrenched in cultural biases, social, economic and educational discrepancies and the implementation of public welfare policies. There were few studies that indicated the importance of strengthening social movements that elicit discussion related to the elderly in Brazil. The conclusion reached is that the study will provide material for reflection about the construction of a new reality about aging in Brazil.

    In this study reported are results from an algorithm intercomparison initiative aimed at the development of improved estimates of surface radiative fluxes from satellite observations over the Amazon Basin. Three algorithms are used: (UMD-SRB, University of Maryland; GL1.2, INPE, Brazil; and Brasil-SR, INPE and University of Santa Catarina, Brazil). The algorithms are physically based, yet differ in their implementation and the way they address issues specific to this region, such as aerosols from biomass burning. Two fifteen day periods in 2005 were selected representing the rainy and dry seasons. The same satellite observations from GOES E were used by all the models. Ground truth from existing stations in the Amazon as well as from a new solar monitoring network of high quality have been used in evaluation. Using daily mean values for the March rainy season, it was found that: 1) the Brasil-SR and UMD-SRB estimates bear a close resemblance; 2) higher irradiances for Petrolina (semi-arid region in Northeast Brazil) are best described by the UMD-SRB and Brasil-SR, probably due to better assessment of water vapor column and absorption parameterization; 3) the GL1.2 results shows a systematic deviation, underestimating daily mean by about 20 Wm-2, but have lower dispersion than UMD-SRB or Brasil-SR; 4) irradiance interval 180 < E < 250 Wm-2 seems better described by GL1.2. This last behavior may be related to better assessment of cloudiness under partial coverage situations. September is characterized by intensive biomass burning in several Brazilian regions, particularly in the Amazon. The Northeast region is not affected by aerosols and estimates from all three models are in close agreement and have similar characteristics to those of March. For the Amazon sites: 1) lower irradiances (for overcast days) are correctly assessed; 2) UMD-SRB and Brasil-SR overestimate solar radiation, especially for higher irradiances (lower cloudiness); 3) GL1.2 model does not include

    Introducción: se desconoce y es necesario entender con mayor claridad y precisión cuál es la asociación entre la diabetes, la hipoacusia y la depresión. Nuestro objetivo fue estimar la asociación entre depresión e hipoacusia en pacientes con diabetes tipo 2 (DT2). Métodos: estudio transversal analítico. Se estudiaron pacientes con DT2 mayores de 40 años. Se registraron medidas antropométricas y parámetros bioquímicos. Se aplicó el cuestionario de depresión de Beck y un estudio audiológico tonal. Se compararon los grupos con chi cuadrada y regresión logística. Resultados: se incluyeron 150 pacientes (76 % mujeres). El promedio de edad fue de 56 ± 9.3 años, con 12.4 ± 6.5 años de evolución de diabetes, con peso de 67.4 ± 11.6kg; fueron obesos el 31 %; 25.5 % hipertensos (126.3 ± 19.3/79.4 ± 19.7 mm Hg) y el 80.7 % presentó descontrol metabólico (HbA1c ≥ 7 %). El 45.3 % presentó hipoacusia y el 32.4 % depresión. El diagnóstico de depresión en pacientes con hipoacusia permaneció significativo después de ajustar para conseguir confusores (razón de momios [RM] = 2.3; intervalo de confianza [IC] al 95 % 1.051-5.333, p = 0.037). Las mujeres tuvieron mayor riesgo de padecer depresión, diferencia que permaneció significativa al ajustarse (RM = 3.2; IC 95 % 1.268-8.584, p = 0.014). Conclusiones: casi la mitad de los pacientes con diabetes presentaron hipoacusia y más de tres veces el riesgo de depresión. Los sujetos con depresión y diabetes mostraron mayor hipoacusia (> 20 dB) que aquellos sin diabetes o sin depresión.

    A comunidade astronômica brasileira de há muito almeja ter a sua disposição um instrumento científico com o qual possa fazer pesquisa de vanguarda e manter a competitividade científica a nível internacional. Hoje este sonho se torna uma realidade. O Brasil tem tido uma política de pesquisa e de pós-graduação bem sucedida. Estamos formando 7000 doutores por ano e produzimos 1,5% da ciência mundial. Nosso desafio, hoje, é associar a esta capacidade de gerar conhecimento também a capacidade de usar o conhecimento em beneficio da sociedade. A Astronomia não é exceção. Temos 7 programas de pós-graduação em nível de doutorado e 11 em nível de mestrado. O telescópio SOAR será o principal instrumento que sustentará estes programas nas próximas décadas. A inauguração do telescópio SOAR simboliza de forma concreta e decidida o apoio do MCT, do CNPq e da FAPESP para o financiamento à pesquisa básica em nosso país. O Laboratório Nacional de Astrofísica, criado a cerca de 20 anos pelo CNPq, a par do Laboratório Nacional de Luz Sincrotron, são até hoje, os únicos laboratórios nacionais do Brasil e ambos voltados basicamente ao avanço do conhecimento. Os vinte anos de existência do LNA foram decisivos para a estruturação da comunidade astronômica no Brasil e para a construção das parcerias como o SOAR.

    Background Evidence suggests a possible bidirectional connection between cardiovascular disease (CVD) and the frailty syndrome in older people. Purpose To verify the relationship between CVD risk factors and the frailty syndrome in community-dwelling elderly. Methods This population-based study used data from the Fragilidade em Idosos Brasileiros (FIBRA) Network Study, a cross-sectional study designed to investigate frailty profiles among Brazilian older adults. Frailty status was defined as the presence of three or more out of five of the following criteria: unintentional weight loss, weakness, self-reported fatigue, slow walking speed, and low physical activity level. The ascertained CVD risk factors were self-reported and/or directly measured hypertension, diabetes mellitus, obesity, waist circumference measurement, and smoking. Results Of the 761 participants, 9.7% were characterized as frail, 48.0% as pre-frail, and 42.3% as non-frail. The most prevalent CVD risk factor was hypertension (84.4%) and the lowest one was smoking (10.4%). It was observed that among those participants with four or five risk factors there was a higher proportion of frail and pre-frail compared with non-frail (Fisher’s exact test: P=0.005; P=0.021). Self-reported diabetes mellitus was more prevalent among frail and pre-frail participants when compared with non-frail participants (Fisher’s exact test: P≤0.001; P≤0.001). There was little agreement between self-reported hypertension and hypertension identified by blood pressure measurement. Conclusion Hypertension was highly prevalent among the total sample. In addition, frail and pre-frail older people corresponded to a substantial proportion of those with more CVD risk factors, especially diabetes mellitus, highlighting the need for preventive strategies in order to avoid the co-occurrence of CVD and frailty.

    A model for estimating wheat yields on the farm level was developed, that integrates the Landsat TM data and agrometeorological information. Results obtained for a test site in southern Brasil for years of 1986 and 1987 show that the vegetation index derived from Landsat TM could account for the 60 to 40 percent wheat-yield variability observed between the two crop years. Compared to results using either the Landsat TM vegetation index or the agrometeorological data alone, the joint use of both types of data in a single model yielded a significant improvement.

    Introducción: La Escala de Neofobia Alimentaria (ENA), desarrollada originalmente en lengua inglesa, ha sido ampliamente utilizada en diferentes estudios para evaluar el deseo individual de probar nuevos alimentos. Sin embargo, es necesario un proceso de traducción y adaptación cultural para permitir su uso en otros países. Objetivo: traducir y validar la ENA en portugués brasileño. Métodos: la escala fue traducida al portugués, de forma independiente, por tres profesores de inglés, siendo traducido al revés al inglés por otros tres profesionales del sector. Se entregaron estas traduciones a una muestra de 40 estudiantes de posgrado de la Universidad de Campinas, São Paulo (Brasil), entre septiembre y octubre de 2014. La reproducibilidad entre los instrumentos se evaluó por medio del coeficiente de correlación intraclase (CCI). La confiabilidad interna de la escala se evaluó por medio del coeficiente alfa de Cronbach. La puntuación total de la ENA varió 10-70 y los individuos fueron clasificados con neofilia alimentaria (≤ 16,4), neutralidad (16,5-38,5) y neofobia alimentaria (≥ 38,6). Resultados: el CCI entre los ítems de la versión original y traducida se situó entre 0,266 y 0,815 (p < 0,05) y la puntuación total de la ENA fue 0,903 (p < 0,001). El coeficiente alfa de Cronbach fue 0,916. La mayoría de los encuestados fueron clasificados como neutrales (72,5%), el otro 10% como neofilia y solo el 17,5% con neofobia alimentaria. Conclusiones: la versión brasileña de la ENA resultó ser una herramienta adecuada y confiable para medir la neofobia alimentaria. No obstante, se necesitan investigaciones futuras para evaluar la presencia de neofobia alimentaria en la población brasileña y para analizar su impacto en la conducta alimentaria.

    The Idaho National Laboratory (INL) in collaboration with the U.S. Geological Survey (USGS) with the assistance of the Empresa de Pesquisa Energetica (EPE) and the Agencia Nacional de Energia Electrica (ANEEL) has performed a comprehensive assessment of the hydropower potential of all Brazilian natural streams. The methodology by which the assessment was performed is described. The results of the assessment are presented including an estimate of the hydropower potential for all of Brazil, and the spatial distribution of hydropower potential thus providing results on a state by state basis. The assessment results have been incorporated into a geographic information system (GIS) application for the Internet called the Virtual Hydropower Prospector do Brasil. VHP do Brasil displays potential hydropower sites on a map of Brazil in the context of topography and hydrography, existing power and transportation infrastructure, populated places and political boundaries, and land use. The features of the application, which includes tools for finding and selecting potential hydropower sites and other features and displaying their attributes, is fully described.

    The toxicity and immunochemical properties of Tityus pachyurus Pocock scorpion venom was characterized, as well as the neutralization capacity against it by three anti-scorpion antivenoms (Alacramyn, Instituto Bioclón, México; Suero antiescorpiónico, Instituto Butantán, Sao Paulo, Brasil; and Suero antiescorpiónico, Centro de Biotecnología, Universidad Central de Venezuela, Caracas, Venezuela). The venom yield, obtained by manual milking, 680+/-20 microg venom, a 50% lethal dose in mice was 4.8 microg/kg (90 microg for an 18-20 g mouse). The most common symptoms of venom poisoning in mice were sialorrhea, respiratory distress, profuse sweating, ataxia, behavior alterations (restlessness, somnolence) and hyperglycemia at 3 and 24 hours after subcutaneous venom injection (0.5 LD50). The neutralizing capacity of Bioclón (México City) and Butantán (Sao Paulo) antivenoms (for a 50% effective dose) was 330 and 292 microg venom/ml antivenom, respectively. The Biotecnología (Caracas) antivenom did not neutralize the lethal effect of venom. By electrophoresis (SDS-PAGE) was demonstrated that the venom contains proteins from less than 14 kd to 97 kd. The Western blots indicated immunological reactivity of the three antivenoms with most of venom components, including proteins of low molecular mass (<14 kd). The results allow to conclude that T. pachyurus venom is neutralized efficiently by anti-scorpion antivenoms produced in México and Brasil.

    The North region is the second region in Brazil with the highest incidence rate of diarrheal diseases in children under 5 years old. The aim of this study was to investigate the relationship between rainfall and water level during the rainy season principally with the incidence rate of this disease in a southwestern Amazon basin. Rainfall estimates and the water level were correlated and both of them were correlated with the diarrheal incidence rate. For the Alto Acre region, 2 to 3 days' time-lag is the best interval to observe the impact of the rainfall in the water level (R = 0.35). In the Lower Acre region this time-lag increased (4 days) with a reduction in the correlation value was found. The correlation between rainfall and diarrheal disease was better in the Lower Acre region (Acrelândia, R = 0.7) and rainfall upstream of the city. Between water level and diarrheal disease, the best results were found for the Brasiléia gauging station (Brasiléia, R = 0.3; Epitaciolândia, R = 0.5). This study's results may support planning and financial resources allocation to prioritize actions for local Civil Defense and health care services before, during and after the rainy season.

    Introducción: Brasil está experimentando una transición nutricional caracterizada por una reducción en la prevalencia de deficiencias nutricionales y un aumento del sobrepeso y la obesidad, no sólo en los adultos sino también en los niños y los adolescentes. Objetivos: Este estudio se diseñó para evaluar los factores asociados con el sobrepeso y la obesidad en preescolares brasileños de 5 años de edad. Métodos: Se realizó un estudio transversal de una cohorte de 232 preescolares nacidos en Diamantina/ Minas Gerais, Brasil. Los datos, que incluían situación socioeconómica, antropometría, dieta, antecedentes de los preescolares y familiares, se recogieron entre julio de 2009 y julio de 2010. Para identificar los factores asociados con sobrepeso y obesidad, se realizaron una regresión logística y un modelo jerárquico. Resultados: El sobrepeso y la obesidad ocurrieron en el 17,2 % de los preescolares. Tras ajustar para obesidad materna, la renta per cápita, la ingesta de alimentos, la ganancia de peso entre los 0-4 meses de edad y el tiempo dedicado al juego, los factores asociados con el sobrepeso y la obesidad que alcanzaban una significación estadística fueron la obesidad materna [OR = 3,12 (IC al 95 % 1,41- 6,91), P = 0,01], la ganancia de peso de más de 0,85 kg/mes en los primeros 4 meses de vida [OR = 2,16 (IC al 95 % 1,01-4,64), P = 0,04] y una menor renta per cápita [OR = 0,32 (IC al 95 % 0,13-0,79), P = 0,01]. Conclusión: Los resultados muestran que la mayor ganancia de peso durante los 4 primeros meses de vida y tener una madre obesa aumentan las probabilidades de sobrepeso/obesidad en los preescolares, mientras que una menor renta per cápita es un factor de protección.

    This article is a theoretical-reflexive study that aims to discuss the development and changes in the quality of healthcare assistance to the patient over the years in Brazil, in light of the policies of control and prevention of Healthcare-associated Infection (HAI). Aspects of HAI and the process of change in health policy in Brazil, as well as the quality of assistance associated with its control, are approached in relation to policies of patient safety. There are various new theoretical and practical proposals created in Brazil. In spite of the difficulty of measuring patient safety, directed to the prevention and control of HAI, we emphasize that to only create policies and establish norms, guidelines, and indicators is not sufficient. If no structural support or conditions exist for interventions in the practices of healthcare professionals, aiming at results in acceptable levels, the control of HAI will not be achieved. Resumo Trata-se um estudo teórico-reflexivo, que objetiva discutir a evolução e as mudanças na qualidade da assistência ao paciente, ao longo dos anos no Brasil, à luz das políticas de controle e prevenção da Infecção Relacionada à Assistência à Saúde (IRAS). Aspectos sobre IRAS e o processo de mudança nas políticas de saúde no Brasil, bem como a qualidade da assistência associada ao seu controle, são abordados em relação às políticas de segurança do paciente. Há novas e várias propostas teóricas e práticas criadas no Brasil. Apesar da dificuldade de medir a segurança do paciente, direcionada à prevenção e controle das IRAS, enfatiza-se que somente criar políticas, estabelecer normas, diretrizes e indicadores não são suficientes. Se não houver suporte de estrutura e condições para as intervenções nas práticas dos profissionais na assistência prestada ao paciente, visando resultados em níveis aceitáveis, o controle das IRAS não será alcançado.

    Objetivo: Evaluar la adecuación de las ecuaciones de predicción para la estimación del gasto energético (GE), en comparación con el GE medido por calorimetría indirecta en una muestra de mujeres brasileñas y españolas con exceso de peso corporal. Métodos: Se trata de un estudio transversal con 92 mujeres adultas obesas [26 brasileñas —G1— y 66 españolas —G2— (20-50 años)]. Se evaluó el peso y la talla durante el ayuno para el cálculo del índice de masa corporal y las ecuaciones de predicción. Se evaluó el GE usando la calorimetría indirecta de circuito abierto con campana respiratoria. Resultados: En G1 y G2, se encontró que las estimaciones obtenidas por Harris-Benedict, Shofield, FAO/OMS/ ONU y Henry y Rees no difieren del GE estimado por calorimetría indirecta, la cual presentó valores más altos que las ecuaciones propuestas por Owen Mifflin -St Jeor y Oxford. Para G1 y G2 la ecuación predictiva que presentó valores más cercanos al valor obtenido por la calorimetría indirecta fue la FAO/OMS/ONU (7,9% y 0,46% subestimación, respectivamente), seguido por Harris-Benedict (8,6% y 1,5% subestimación, respectivamente). Conclusión: Las ecuaciones propuestas por la FAO/ OMS/ONU, Harris-Benedict, Shofield y Henry & Rees fueron adecuadas para estimar el GE en una muestra de mujeres brasileñas y españolas con exceso de peso corporal. Las otras ecuaciones subestimaron el GE.

    2015-12-01

    Bacterial diarrheal diseases have a high incidence rate during and after flooding episodes. In the Brazilian Amazon, flood extreme events have become more frequent, leading to high incidence rates for infant diarrhea. In this study we aimed to find a statistical association between rainfall, river levels and diarrheal diseases in children under 5, in the river Acre basin, in the State of Acre (Brazil). We also aimed to identify the time-lag and annual season of extreme rainfall and flooding in different cities in the water basin. The results using Tropical Rainfall Measuring Mission (TRMM) Satellite rainfall data show robustness of these estimates against observational stations on-ground. The Pearson coefficient correlation results (highest 0.35) indicate a time-lag, up to 4 days in three of the cities in the water-basin. In addition, a correlation was also tested between monthly accumulated rainfall and the diarrheal incidence during the rainy season (DJF). Correlation results were higher, especially in Acrelândia (0.7) and Brasiléia and Epitaciolândia (0.5). The correlation between water level monthly averages and diarrheal diseases incidence was 0.3 and 0.5 in Brasiléia and Epitaciolândia. The time-lag evidence found in this paper is critical to inform stakeholders, local populations and civil defense authorities about the time available for preventive and adaptation measures between extreme rainfall and flooding events in vulnerable cities. This study was part of a pilot application in the state of Acre of the PULSE-Brazil project (http://www.pulse-brasil.org/tool/), an interface of climate, environmental and health data to support climate adaptation. The next step of this research is to expand the analysis to other climate variables on diarrheal diseases across the whole Brazilian Amazon Basin and estimate the relative risk (RR) of a child getting sick. A statistical model will estimate RR based on the observed values and seasonal forecasts (higher

    This article is a theoretical-reflexive study that aims to discuss the development and changes in the quality of healthcare assistance to the patient over the years in Brazil, in light of the policies of control and prevention of Healthcare-associated Infection (HAI). Aspects of HAI and the process of change in health policy in Brazil, as well as the quality of assistance associated with its control, are approached in relation to policies of patient safety. There are various new theoretical and practical proposals created in Brazil. In spite of the difficulty of measuring patient safety, directed to the prevention and control of HAI, we emphasize that to only create policies and establish norms, guidelines, and indicators is not sufficient. If no structural support or conditions exist for interventions in the practices of healthcare professionals, aiming at results in acceptable levels, the control of HAI will not be achieved. Resumo Trata-se um estudo teórico-reflexivo, que objetiva discutir a evolução e as mudanças na qualidade da assistência ao paciente, ao longo dos anos no Brasil, à luz das políticas de controle e prevenção da Infecção Relacionada à Assistência à Saúde (IRAS). Aspectos sobre IRAS e o processo de mudança nas políticas de saúde no Brasil, bem como a qualidade da assistência associada ao seu controle, são abordados em relação às políticas de segurança do paciente. Há novas e várias propostas teóricas e práticas criadas no Brasil. Apesar da dificuldade de medir a segurança do paciente, direcionada à prevenção e controle das IRAS, enfatiza-se que somente criar políticas, estabelecer normas, diretrizes e indicadores não são suficientes. Se não houver suporte de estrutura e condições para as intervenções nas práticas dos profissionais na assistência prestada ao paciente, visando resultados em níveis aceitáveis, o controle das IRAS não será alcançado.

    Introdução: O objectivo deste estudo é avaliar a performance dos sistemas de saúde através dos internamentos evitáveis, dado que estes têm vindo a ganhar importância a nível internacional. Foram utilizadas duas metodologias distintas para a identificação dos internamentos por Ambulatory Care Sensitive Conditions, fazendo uma descrição da realidade e a evolução destes em Portugal. Material e Métodos: Analisámos mais de 12 milhões de internamentos entre 2000 e 2012, utilizando as bases de dados de resumos de alta nacionais. Utilizaram-se duas metodologias de identificação das Ambulatory Care Sensitive Conditions, determinando a sua concordância. Calculámos cenários de melhoria potencial. Resultados: Em 2012, 4,4% e 32,5% dos internamentos por causas médicas seriam evitáveis segundo a metodologia canadiana e espanhola respectivamente. Os internamentos são mais frequentes nas crianças e nos idosos, divergindo as suas causas de acordo com o grupo etário e a metodologia utilizada. A taxa de internamentos no período em análise diminuiu 20% segundo a metodologia canadiana e aumentou 16% segundo a espanhola. Existem agregados regionais de performance acima e abaixo da média nacional. A concord ncia entre as duas metodologias é baixa. Estimaram-se reduções potenciais entre 20,3% e 53,5% dos internamentos.Discussão: Os internamentos evitáveis assumem um volume considerável em Portugal. Apesar de em teoria serem evitáveis a sua eliminação por completo não é uma possibilidade prática, no entanto, o seu estudo possibilita a avaliação e monitorização de resultados e o estabelecimento de prioridades de intervenção. Conclusão: Para uma caracterização mais precisa dos internamentos evitáveis é necessário consensualizar em Portugal a metodologia para a sua identificação.

    Chronic Non-Communicable Diseases are the main source of disease burden in Brazil. In 2011, the Brazilian Ministry of Health launched the Strategic Plan of Action for Management of Chronic Non-Communicable Diseases focusing on population-based interventions to manage cardiovascular diseases, diabetes, cancer, and chronic respiratory diseases mainly through fighting tobacco use, unhealthy diets, physical inactivity and the harmful use of alcohol. Although a significant number of scientific studies on chronic diseases and their risk factors have been undertaken in Brazil, few are of cohort design. In this context, the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil), a cohort study of 15,105 Brazilian public servants reflects the reality of high prevalences of diabetes, hypertension and the main chronic diseases risk factors. The diversity of information that the Study will produce can provide important input to better understand the causes of chronic diseases and to support public policies for fighting them.

    The current article presents the process of situated modeling in the drawing workshop for bobbin lace developed and implemented in the Núcleo de Produção Artesanal Rendeiras da Vila, in Ponta Negra, Natal-Brasil. The workshop aimed to rescue the domain over the product in the production of bobbin lace through capacitation of both experienced and novice craftswomen. The modeling of the drawing workshop was grounded on the sociotechnical construction and in the concepts of anthropotechnology and also social technology. The modelling required an intense process of social construction involving the members of GREPE-UFRN (Group of extension and Research in Ergonomics) and the lacemakers od the community. The domain of drawing the lace has enabled the expression of the craftswomen creativity, increasing the amount of works and the sustainable development,thus reducing the risks of extinction of such art in the Village of Ponta Negra.

    We received for examination a small colection of ticks captured in the National Park of the Serra da Canastra (MG), between 1979 and 1980. The authors demonstrated the existence of a broad co-accomodation of Amblyomma pseudoconcolor on Edentata of the family Dasypodidae, being Dasypodini the tribe more adjusted to this infestation. In conformity to the Figs 1 and 2, Dasypodini are probably the real hosts of A. pseudoconcolor and also the oldest hosts. For the first time, A. pseudoconcolor is also recorded on Cabassous tatouay, C. unicinctus, Priodontes maximus and Euphractus sexcincuts. Also for the first time A. pseudoconcolor and Amblyomma calcaratum were recorded in the State of Minas Gerais.

The lack of successful precedents at UB isolated him to one inexpressive chair. The equipment available was inadequate for his purposes; there were no official sources and forms of access to funding for science or trained personnel for research activities. On the other hand, Chagas Filho won over allies due both to the political and social clout of his name and his marriage, and to his scientific influence ensuing from his success in attaining the goals he fought for.

    Remote sensing techniques for supporting the rural credit supervision system were developed and tested. The test area comprised the counties of Aracatuba and Guararapes, located in the State of Sao Paulo. Aerial photography, LANDSAT images and topographic charts were used. Aerial photographs were extremely useful for the out lining of properties boundaries with financing of sugarcane plantations by the Banco do Brasil S.A.. The percentage of correctly interpreted sugarcane on LANDSAT images, considering the 85 analyzed properties, was of 63.12%. The occurrence of atypical conditions such as excessive raining, sugarcane in bloom, and wind damaged sugarcane and sugarcane not harvested due to planning failures verified during the period the images were obtained, were some of the contributing factors associated with a low interpretation performance. An alternative approach was developed using several LANDSAT overpasses and auxiliary field data, which resulted in 91.77 percent correct.

    A new species of Solanum from Brazil is described. Solanum evolvuloides Giacomin & Stehmann, sp. nov. belongs to section Gonatotrichum, a small group assigned to the Brevantherum Clade of the genus Solanum. It resembles Solanum turneroides Chodat, sharing with it heterandry, and Solanum parcistrigosum Bitter, with which it shares a similar habit and pubescence. Despite these similarities, the species can be recognized by its ovate-elliptic to cordiform leaf shape and more membranaceous leaf texture than the other species in the section, and stem, inflorescence axes, and calyx vestiture mainly composed of glandular hairs. Solanum evolvuloides is known to occur only in southeastern of Bahia state, Brazil, and in a preliminary assessment of the IUCN criteria can be considered a threatened species.ResumoUma nova espécie de Solanum é descrita para o Brasil. Solanum evolvuloides Giacomin & Stehmann, sp. nov. é componente da seção Gonatotrichum, um pequeno grupo associado ao Clado Brevantherum. A espécie é similar a Solanum turneroides, com a qual compartilha a heterandria, e Solanum parcistrigosum, que por sua vez apresenta um hábito e indumento foliar semelhante. Apesar da similaridade, a espécie pode ser facilmente reconhecida pela forma da folha ovada-elíptica a cordiforme e pela texura mais membranácea que as outras espécies da seção, além do indumento do caule, eixo da inflorescência e cálice, constituído em sua maioria por tricomas glandulares pedicelados. Solanum evolvuloides tem sua distribuição conhecida somente para o sudeste do estado da Bahia, Brasil, e é indicada como uma espécie ameaçada de extinção. PMID:22287920

  3. Nutritional status of children under 5 years of age in the Brazilian Western Amazon before and after the Interoceanic highway paving: a population-based study

    PubMed Central

    2013-01-01

    Background The aim of this study was to analyse the prevalence of undernutrition, overweight and associated factors, before and after the implementation of the Interoceanic Highway. Methods A population-based cross-sectional study on children under 5 years of age was conducted in the municipality of Assis Brasil, AC, Brazil, in 2003 and 2010. Prevalence of undernutrition was observed by using height-for-age Z-scores (HAZ) and adopting a cut-off point equal to or lower than a -2 Z-score. Overweight prevalence was defined by a cut-off point equal to or greater than a +2 Z-score of the WHZ index. Z-scores were calculated relative to WHO 2006 reference data. Semi-structured questionnaires were applied to the children’s guardians, investigating family socio-economic and demographic characteristics, morbidities, access to services and child care. Associated factors were identified by hierarchical multiple logistic regression analysis. Results The prevalence of low HAZ (undernutrition) was 7.0% in 2003 and 12.2% in 2010. The prevalence of high WHZ (overweight) was 1.0% and 6.6% for 2003 and 2010, respectively. It was not possible to adjust the multiple model for the year 2003. The factors associated with low HAZ in 2010 were: wealth index, the situation of living with biological parents, maternal height and presence of open sewage, whereas the factors associated with a high WHZ in the same year were: child’s age, mother’s time of residence in the location, mother’s body mass index. Conclusions Overweight increase within this undernutrition scenario reveals that the process of nutritional transition began in this Amazonian city only in the last decade, and therefore, it is delayed when compared to overweight in other parts of Brazil. Such nutritional transition in Assis Brasil may have been facilitated by the construction of the Interoceanic Highway. PMID:24283293

    Introducción: la relación entre alimentación temprana y presión arterial en etapas posteriores de la vida todavía se muestra incierta y, a veces, contradictoria. Algunas investigaciones apuntan hacia el efecto protector de la lactancia materna sobre la enfermedad cardiovascular, mientras que otras no obtienen resultados concluyentes. Objetivos: el objetivo de este estudio fue analizar la relación entre patrones de lactancia durante los primeros meses de vida y tensión arterial en la infancia, en dos muestras de niños y niñas procedentes de dos poblaciones con características socioculturales diferentes, controlando el efecto de la calidad de la alimentación en la infancia. Métodos: el estudio, de diseño transversal y retrospectivo, se realizó con 492 escolares de edades comprendidas entre los 8 y los 10 años, y se compone de dos muestras, ambas recogidas en colegios públicos, una en Madrid (España) y otra en Vitória, Espírito Santo (Brasil). Resultados: el 90% de la muestra fue amamantado en algún momento, 196 (44,2%) en Madrid y 247 (55,7%) en Vitória/ES. La duración media de la lactancia materna exclusiva (LME) en Madrid fue de 12,89 semanas (std=9,6) y en Vitória/ES de 22,00 semanas (std= 13,4), siendo estas diferencias estadísticamente significativas. Los valores medios de presión arterial sistólica, diastólica y media fueron significativamente superiores en la muestra brasileña. La prevalencia de hipertensión limítrofe y de hipertensión también fue mayor en la muestra brasileña que en la española, 68% vs 32% y 60% vs 40%, respectivamente. En las dos muestras se observó asociación entre una duración más corta de LME y mayor prevalencia de hipertensión en la infancia. Con respecto a la asociación entre calidad de la alimentación y valores de presión arterial, esta fue solo significativa en la muestra brasileña, pero no en la española.

    Introdução: Os profissionais dos cuidados de saúde primários encontram-se numa posição privilegiada para identificarem e orientarem casos de maus-tratos de idosos. Este estudo investigou o enquadramento destes profissionais nesta matéria. Material e Métodos: Elaborou-se um questionário posteriormente aplicado a Médicos e enfermeiros de 12 Unidades de Saúde de Coimbra. Estudaram-se par'metros relacionados com aspetos demográficos, perceção do abuso e estratégias de atuação, experiência pessoal e formação nesta área. Resultados: A taxa global de resposta foi de 67,9% com 127 questionários validados. Dos resultados obtidos destacam-se seguintes: verificou-se um contacto substancial entre os profissionais e a população idosa; a maioria dos profissionais (64,6%) consideram o abuso mais prevalente em contexto familiar e 32,3% indicaram a negligência como a forma mais frequente; 97,6% dos profissionais considera que tem um papel importante na deteção de casos de abuso; a incerteza no diagnóstico foi um dos principais fatores limitadores da denúncia; verificou-se incerteza a obrigatoriedade de reportar os casos às autoridades judiciais. Ainda se constatou que 87,4% destes profissionais se sentiriam mais confortáveis com protocolos de atuação e que esta problemática não havia sido abordada na sua formação básica em 70,9% dos casos. Discussão: O contato significativo entre a população idosa e os profissionais de saúde propicia o diagnóstico e intervenção precoces. Os profissionais revelaram conhecimentos sobre o tema em linha com os indicados por alguns estudos, nomeadamente, sobre o contexto e prevalência do abuso. A subsistência de dúvidas relativamente à melhor forma para gerir estes casos e conciliar as diferentes perspetivas poderia ser colmatado, na opinião veiculada pelos próprios, pela definição de protocolos de atuação e a formação específica deverá ser considerada como um dos pilares fundamentais para

    Objetivos: Estimar la prevalencia de obesidad y sobrepeso, obesidad abdominal y hipertensión arterial en una muestra de adolescentes pertenecientes a una ciudad de baja renta en Brasil y su relación con el nivel socioeconómico, nivel educativo de lo responsable de la familia y tipo de escuela. Métodos: Estudio transversal con una muestra de 1014 adolescentes (54,8% chicas), con edades entre 14-19 años, estudiantes de las escuelas de la ciudad de Imperatriz (Brasil), seleccionadas por un muestreo aleatorio. Las variables dependientes evaluadas son: obesidad general y sobrepeso, obesidad abdominal, y tensión arterial alta (sistólica y/o diastólica). Las variables independientes son: nivel socioeconómico de la familia (NSO), el nivel de educación de lo responsable de la familia (NERF) y tipo de escuela. Las variables de confusión son: sexo, edad y nivel de actividad física. La prevalencia fue estimada, y la asociación entre las variables dependientes y las variables independientes se analizaron mediante razón de prevalencia (RP), con intervalo de confianza (IC) del 95%, estimado por la regresión de Poisson. Resultados: La prevalencia de la obesidad general fue de 3,8%, sobrepeso 13,1%, obesidad abdominal 22,7% y la tesión arterial alta 21,3%. Las análisis ajustadas indicaron que las chicas con NSO alto tienen mayor probabilidad de tener sobrepeso (RP=1,71 [IC95%: 1,13 a 2,87]), y chicos de las escuelas privadas tienen más probabilidad de tener obesidad (RP=1,79 [IC95%: 1.04- 3,08]) y obesidad abdominal (RP=1,64 [IC95%: 1,06 a 2,54]). Conclusión: La prevalencia de los FRC es alta en adolescentes de una región de baja renta. Los chicos de las escuelas privadas son más propensos a tener obesi dad y obesidad abdominal, y las chicas con NSO alto son más propensas a tener sobrepeso.

    Introdución: El análisis de la composición corporal a través de métodos directos e indirectos permite el estudio de los distintos componentes del cuerpo humano, constituyéndose en el eje central para valorar el estado nutricional. Objetivo: Desarrollar ecuaciones de predicción del % de grasa corporal a partir de circunferenciales corporales del brazo, cintura y pantorrilla y proponer percentiles para diagnosticar el estado nutricional de niños escolares de ambos sexos de 4-10 años. Métodos: Fueron seleccionados de forma intencional (noprobabilística) 515 niños, siendo 261 niños y 254 niñas pertenecientes al Programa de interacción y desarrollo del niño y del adolescente de la Universidad Estatal de Campinas (Sao Paulo, Brasil). Se evaluó las variables antropométricas de peso, estatura, pliegues cutáneos tricipital y subescapular y las circunferencias corporales del brazo, cintura y pantorrilla. Se determino el % de grasa a través de la ecuación propuesta por Boileau, Lohman y Slaughter (1985). A través del método de regresión se generaron 2 ecuaciones para predecir el porcentaje de grasa a partir de las circunferencias corporales; las ecuaciones 1 y 2 fueron validadas a través del método de validación cruzada. Resultados: Las ecuaciones obtenidas mostraron altos valores predictivos, oscilando con un R2 = 64-69%. En la validación cruzada entre el criterio y las ecuaciones de regresión propuestas no hubo diferencias significativas (p < 0,05) y se observó un alto grado de concordancia a un CI 95%. Conclusión: Las ecuaciones son validadas y son una alternativa para evaluar el porcentaje de grasa en niños escolares de ambos sexos de 4-10 años del Programa de interacción y desarrollo del niño y del adolescente de la Universidad Estatal de Campinas (Sao Paulo, Brasil).

    Cape São Tomé, in the Campos Basin, is a region of intense ocean mesoscale activity where meanders and eddies are formed by instability processes of the Brazil Current. In this work seven years of ADCP current data (2006-2012) are analyzed at different depths over the continental shelf and slope of Campos Basin in order to characterize the variability and vertical struture of meanders and eddies. The present study is a continuation of Lima et al. (2010), in which two years of current meter data, taken at fewer locations and spanning a shorter depth range, were analyzed. This preliminary study suggested that eddy formation at Cape São Tomé may occur throughout the year, and that these eddies, which present a mixed barotropic and baroclinic structure, exert significant influence on the Brazil Current and on the upper portion of the Intermediate Western Boundary Current, which flows northward at intermediate depths. The longer time series of data, now available, alow us to check the validity of Lima et al. (2010) results about mesoscale activity activity, and to test their proposed conceptual model of eddy formation for other events. The ten ADCP moorings analyzed were located between 21°S and 23°S, and 41°W and 39°W. Measurements were taken from the surface down to 750 and 900 meters, and the data have different record lengths for each mooring. High Resolution Sea Surface Temperature dates (GHRSST) are also analyzed in order to provide a broader spatial view, assisting in the interpretation of the phenomena observed in the velocity data. The new results corroborate the study of Lima et al. (2010), showing that eddy formation is a reccuring phenomenon at Cape São Tomé for all the period analyzed. Eddies generate significant variability in current velocity both at the surface and at intermediate depths, changing the depth and intensity of Brasil Current - Intermediate Western Boundary Current system. While the average current system showed a strong baroclinic

    Objetivo: Identificar la prevalencia de insatisfacción corporal y factores asociados entre estudiantes de Salvador en Brasil. Métodos: Estudio transversal realizado en una muestra aleatoria de 1494 adolescentes (852 niñas y 642 niños) de entre 11 y 17 años de edad estudiantes de escuelas públicas en Salvador (Brasil). Los participantes completaron los cuestionarios: Cuestionario de La Figura Corporal y el Inventario de Actitudes Alimentarias. La imagen corporal pudo ser considerada satisfactoria o insatisfactoria. Se obtuvieron datos demográficos, antropométricos y económicos e información sobre la etapa de maduración sexual, la auto-percepción del peso corporal y el consumo de bebidas azucaradas y gaseosas. Para identificar los factores asociados se utilizó el análisis de regresión de Poisson. Resultados: La insatisfacción corporal estuvo presente en el 19,5% de los/as adolescentes, con una prevalencia del 26,6% entre las chicas y el 10% entre los chicos. Independientemente del sexo, la prevalencia de la insatisfacción corporal fue superior entre los/as adolescentes con sobrepeso u obesos (en las niñas, PR: 1,38, IC: 1,09-1,73 y en los niños, PR: 2,26, IC: 1,08-4,75), mayor entre los/as que percibían a sí mismos como “gordos” (en las niñas, PR: 2,85, IC: 2,07-3,93 y en los niños, PR: 3,17, IC: 1,39- 7,23), y entre los/as que tenían actitudes alimentarias negativas (en las niñas, PR: 2,42, IC: 1,91-3,08 y en los niños, PR: 4,67, IC: 2,85-7,63). Una reducción en la insatisfacción corporal se identificó sólo entre las niñas con bajo peso (RP: 0,12, IC: 0,03-0.49).Conclusiones: Se observó una alta ocurrencia de la insatisfacción corporal entre los adolescentes, y que factores biológicos y del comportamiento se asocian con dicha insatisfacción.

    This work proposes the development and applications of a network of high speed cameras for observation and study of lightning flashes. Four high-speed cameras are being acquired to be part of the RAMMER network. They are capable to record high resolution videos up to 1632 x 1200 pixels at 1000 frames per second. A robust system is being assembled to ensure the safe operation of the cameras in adverse weather conditions and enable the recording of a large number of lightning flashes per storm, larger than the values reported to date. As the amount of physical memory to record only 1 second of data is something like 3 - 4 GBytes, there is no way to make long recordings of thunderstorms, so a triggering system was conceived to address this problem and do the recordings of 2 seconds of data automatically for each lightning flash. The triggering system is an optical/electromagnetic system that is being tested since September/2010 and the whole system is under testing yet. This lightning information from the video recordings will be correlated with data from the sensors of the Brazilian Lightning Detection Network (BrasilDAT), from a network of electric field fast antennas, slow electric field antennas and Field-Mills, as well as with data from the LMA (Lightning Mapping Array) to be installed in 2011 in the cities of Sao Paulo and Sao Jose dos Campos. The following objectives are envisaged: a) make the first three-dimensional reconstructions of the lightning channel with high speed cameras and verify its dependence on the physical conditions associated with each storm; b) to observe almost all CG lightning flashes of a single storm cloud in order to compare the physical characteristics of the CG lightning flashes for different storms and their dependence on physical conditions associated with each storm; c) evaluate the performance of the new sensors of BrasilDAT network in different localities and simultaneously. The schematics of the sensors will be shown here, with

  11. Crustal thinning and tectonic geomorphology: redefining the passive margin

    We describe Scandinavia's passive margin in terms of a hyper-extended distal margin, a variably tapered proximal margin that includes the outer onshore areas, and an upwarped, unstretched, continent-sloping hinterland that terminates against the "undeformed" cratonic interior. Two benchmark locations, defined as the taper break (TB) and the Hinterland Break in Slope (HBSL), occur at the inner boundary of the distal margin and at the transition from the continent-sloping hinterland and craton, respectively. The elevation of the seaward-facing escarpment is directly scaled to the distance between the taper break and the Hinterland Break in Slope. Scaling relationships between the taper of the crystalline crust in the direction of the distal margin and the length/dip of the hinterland backslope follow directly. The shape factors of major catchments are directly scaled to the taper of the proximal margin and drainage azimuths are parallel to the mean transport lineation recorded from a distinct population of range-bounding normal faults. Topographic expressions of the footwalls and offsets in apatite fission-track age-patterns indicate that fault movement controlled topography, locally and regionally inboard of sharp crustal tapers long after the main phase of crustal thinning. We extend our definition of the passive margin to other post-breakup margins. One particularly fine example is SE Brasil. New data (Zalan et al., 2011) suggest the direct correlation of SE Brasil's Taper Break with its escarpment elevation in a manner consistent with our Scandinavian and global observations. The Taper Hypothesis appears to hold across old and young, glaciated, and unglaciated margins. Following the stretching, thinning, and exhumation phase, an "accommodation phase" is warranted. During accommodation, the initially elevated escarpments can be eroded to very low base levels and subsequently undergo inboard rejuvenation by footwall uplift, in response to tensile stresses

    Introducción: Estudios nacionales de evolución temporal encuentran que la tendencia del consumo alimentario se asocia con aumento de la prevalencia de las enfermedades crónicas. Objetivos: Caracterizar los hábitos alimentarios de los adolescentes en un área urbana del Noreste de Brasil, relacionándolos con los marcadores dietéticos saludables. Métodos: Estudio transversal con adolescentes (n=430) de las escuelas públicas de Natal-RN, Brasil. El consumo alimentario se evaluó mediante dos recordatorios 24h. La técnica de Análisis de Componentes Principales fue utilizada para derivar patrones dietéticos, de acuerdo con: alimentos en gramos (g), la energía en Kcal y la fibra en gramos, lo que resulta, respectivamente, en 3 componentes principales distintos: 7, 8 y 4 (varianza acumulada >70%; cargas factoriales >0,4). La asociación entre las variables independientes y los escores de los factores de todos los componentes obtenidos, se determinó por la razón de prevalencia (IC 95%). Resultados: Los patrones dietéticos fueron: el (1) Sistema Alimentario Tradicional puro representó el primero componente de los modelos; el (2) Sistema Alimentario Combinado y de riesgo reveló marcadores de alimentación no saludables, debido a la alta frecuencia de azucares refinados, grasas saturadas y sal; y el (3) Sistema Alimentario Modificado fue identificado en el modelo de las fibras, el patrón 1 de nuevo fue observado en este patrón. Las asociaciones observadas, en particular del patrón SATm, distinguen por sexo, edad y estado nutricional. Conclusiones: Los patrones dietéticos 1 y 3 se caracterizaron por la preservación de las prácticas regionales de alimentos, muy saludables, desde el punto de vista de la prevención de las enfermedades crónicas, mientras que el 2 representó alerta y riesgo para la salud. Los hallazgos pueden subvencionar Políticas de Atención a la Salud para infancia y adolescencia en carácter intersectorial.

    The knowledge about and control of thermal energy produced by Er:YAG laser after irradiating hard dental tissues and compound resin is important because the pulp, like all vital biological tissue, has a certain capacity for supporting stimulus. The objective of this study was to analyze the thermal variation generated by Er:YAG laser (λ=2.94μm) during the preparation of a Class I cavity in the dental structure and in the removal of microhybrid Z100 (3M) compound resin. An evaluation was made of 30 maxillary human pre-molar teeth from the bank of the Endodontic Laboratory Center of Ribeirao Preto Dental School, Brasil. The sample was divided into 6 groups of 5 teeth each: Group 1, preparation of Class I cavity with Er:YAG laser (350mJ, 3Hz, 343 impulses, 120J, 113 seconds); Group 2, preparation of Class I cavity with Er:YAG laser (350mJ, 4Hz, 343 impulses, 120J, 81 seconds); Group 3, preparation of Class I cavity with Er:YAG laser (350mJ, 6Hz, 343 impulses, 120J, 58 seconds); Group 4, removal of compound resin from Class I preparation with Er:YAG laser (350mJ, 3Hz, 258 impulses, 90J, 85 seconds); Group 5, removal of compound resin from Class I preparation with Er:YAG laser (350mJ, 4Hz, 258 impulses, 90J, 67 seconds); Group 6, removal of compound resin from Class I preparation with Er:YAG laser (350mJ, 6Hz, 258 impulses, 42 seconds). The laser used was KaVo Key 2 (Biberach, Germany), λ=2,94μm, P=3 Watts, pulse duration of 250μs, with air-water cooling. The increase in temperature during dental preparation and the removal of the compound resin was evaluated by means of a Tektronix DMM916 Thermocouple (Consitec, Brasil). The results showed that the application of laser for the removal of the hard dental tissues and for the removal of compound resins with the pulse frequencies 3, 4 and 6 Hz did not generate heating greater than 3.1°C and remained within the histopathological limits permitted for pulp tissue (5.5°C) and there was a significant statistical

    Introducción: la calidad de vida alterada es común en los pacientes con epilepsia, especialmente debido a las comorbilidades cardiovasculares, el sobrepeso y la obesidad. Objetivos: evaluar el estado nutricional de los pacientes con epilepsia en base a mediciones antropométricas y la ingesta alimentaria. Métodos: este estudio transversal involucró a 72 pacientes reclutados por conveniencia en la Clínica de Epilepsia del Hospital de Clínicas de Porto Alegre, Brasil. La muestra consistió en pacientes de ambos sexos, mayores de 18 años, que habían sido diagnosticados de epilepsia durante al menos un año. Variables investigadas: medidas antropométricas (peso y talla para la evaluación del estado nutricional y el IMC, circunferencia de la cintura para la evaluación del riesgo cardiovascular); la ingesta nutricional en base a un cuestionario de frecuencia de alimentos; nivel socioeconómico basado en los Criterios de Clasificación Económica del Brasil. Resultados: la prevalencia de sobrepeso/obesidad fue del 66,7%, y el 85,4% de las mujeres tenían un alto riesgo cardiovascular. Los pacientes presentaron una baja frecuencia de control de las crisis (41,7%), alta ingesta de carbohidratos y proteínas, así como baja ingesta de ácidos grasos mono y poliinsaturados (incluyendo ácidos grasos omega 3 y 6). No se observaron diferencias en el estado nutricional ni el consumo entre los pacientes con convulsiones controlados o no controlados. Conclusiones: los pacientes con epilepsia tienen riesgos de comorbilidades, como se evidencia por su tendencia al sobrepeso/obesidad y obesidad abdominal. Aunque el control de las crisis no parece estar relacionado con el estado nutricional y la ingesta, la presencia de tales comorbilidades apunta la necesidad de vigilancia nutricional e intervención en estos pacientes, con un enfoque especial en la redistribución de macronutrientes y en los niveles de ácidos grasos en la dieta.

Objetivos: El objetivo era evaluar el papel de ñame brasileño (Dioscorea bulbifera) sobre la glucemia y el hueso parámetros de ratas diabéticas hembra. Métodos: Ratas Wistar hembra con 3 meses de edad fueron asignados en tres grupos. El grupo de control (C, n = 6), tratados con dieta normal de la grasa. Las ratas diabéticas tratadas con dieta alta en grasas y sin (DM, n = 8) y con (DMY, n = 8) harina de ñame liofilizado. Después se cuantificaron 5 semanas del experimento, la glucosa y la insulina en suero, la masa páncreas, el número y el área de islotes del páncreas. Y los parámetros de fémur fueron analizados por absorciometría de rayos X de energía dual (DXA) y la tomografía computarizada (CT). Resultados: Las diferencias se consideraron significativas si P < 0,05. Grupos diabéticos mostraron menor (P < 0,05): el fémur y la masa páncreas, el área de los islotes pancreáticos y la insulina. Sin embargo, DMY mostró inferior (-10%, P < 0,05) concentraciones de glucosa al grupo DM. Fémur, por DXA, mostró menor densidad mineral ósea, el contenido y el área en el grupo de DM. Mientras que el grupo DMY mostró mayor (27%, P < 0,05) radiodensidad de la cabeza femoral en comparación con el grupo de DM. Discusión: Suplemento de harina de ñame brasileña no fijó un defecto, pero alivia las consecuencias de la enfermedad diabética experimental. Se mostró resultados para controlar el aumento de los niveles de glucosa en sangre en ratas diabéticas, lo que sugiere la protección en agentes oxidantes y posponer daño en el hueso. Conclusión: Teniendo en cuenta todos los resultados de este estudio, nuestros resultados sugieren que la harina de ñame actúa de producir beneficios en la diabetes experimental.

    The Norwegian Offshore Stratigraphic Lexicon (NORLEX) provides a relational stratigraphic database for the North Sea, Norwegian Sea, Barents Sea and Svalbard. Both regional lithostratigraphy and biostratigraphy are being substantially updated, following guidelines laid out in the International Stratigraphic Guide. The main body of information developed is available as a petroleum consortium (oracle-style) database, and the new lithostratigraphic definitions as a public domain (paper) document. NORLEX is presented as a browsing website via the internet at http://www.nhm.uio.no/norlex. Seismic cross-sections, core photographs, well logs, field outcrops, microfossil occurrences and other vital attributes are relationally cross-linked. In addition, there are menus for instantly finding updated formation and member tops or microfossil events in all wells, plus a map contouring routine for unit thicknesses and depths. Several new initiatives will expand data and user coverage: 1. Overhaul of Mesozoic stratigraphy, especially Triassic and Cretaceous, in the Barents Sea. 2. Coverage of East Greenland 3. Linkage to UK and Belgium and The Netherlands surface and subsurface stratigraphy 4. Creation of a Sequence Stratigraphic Framework for specific regions. 5. A national microfossil atlas to support zonations 6. Tight linkage to the basin datapacks in TimeScaleCreator Pro, as developed for Australia, New Zealand, Brasil, Gulf of Mexico, Canada and Russia. NORLEX may thus evolve to become STRATLEX, covering many basin regions.

    A small and sophisticated optical depth sensor (ODS) has been designed to work in both Martian and Earth environments. The principal goal of ODS is to carry out the opacity due to the Martian dust as well as to characterize the high altitude clouds at twilight, crucial parameters in understanding of Martian meteorology. The instrument was initially designed for the failed MARS96 Russian mission, and also was included in the payload of several other missions [1]. Until recently, it was selected (NASA/ESA AO) in the payload of the atmospheric package DREAMS onboard the MARS 2016 mission. But following a decision of the CNES, it is no more included in the payload. In order to study the performance of ODS under a wide range of conditions as well as its capable to provide daily measurements of both dust optical thickness and high altitude clouds properties, the instrument has participated in different terrestrial campaigns. A good performance of ODS prototype (Figure 1) on cirrus clouds detection and in dust opacity estimation was previously archived in Africa during 2004-2005 and in Brasil from 2012 to nowadays. Moreover, a campaign in the arctic is expected before 2016 where fifteen ODSs will be part of an integrated observing system over the Arctic Ocean, allowing test the ODS performance in extreme conditions. In this presentation we present main principle of the retrieval, the instrumental concept, the result of the tests performed and the principal objectives of ODS in Mars.

  3. Constructing public oral health policies in Brazil: issues for reflection.

    This paper addresses the construction of public oral health policies in Brazil by reviewing the available literature. It includes a discussion of the social responses given by the Brazilian State to oral health policies and the relationship of these responses with the ideological oral health movements that have developed globally, and that have specifically influenced oral health policies in Brazil. The influence of these movements has affected a series of hegemonic practices originating from both Market Dentistry and Preventive and Social Dentistry in Brazil. Among the state activities that have been set into motion, the following stand out: the drafting of a law to regulate the fluoridation of the public water supply, and the fluoridation of commercial toothpaste in Brazil; epidemiological surveys to analyze the status of the Brazilian population's oral health; the inclusion of oral health in the Family Health Strategy (Estratégia de Saúde da Família - ESF); the drawing up of the National Oral Health Policy, Smiling Brazil (Brasil Sorridente). From the literature consulted, the progressive expansion of state intervention in oral health policies is observed. However, there remains a preponderance of hegemonic "dental" practices reproduced in the Unified Public Health Service (Sistema Único de Saúde - SUS) and the Family Health Strategy.

    This study presents the pore-space system analysis of the 2-ITAB-1-RJ well cores, which were drilled in the São José do Itaboraí Basin, in the state of Rio de Janeiro, Brasil. The analysis presented herein has been developed based on two techniques: nuclear logging and 3D high-resolution X-ray computed microtomography. Nuclear logging has been proven to be the technique that provides better quality and more quantitative information about the porosity using radioactive sources. The Density Gamma Probe and the Neutron Sonde used in this work provide qualitative information about bulk density variations and compensated porosity of the geological formation. The samples obtained from the well cores were analyzed by microtomography. The use of this technique in sedimentary rocks allows quantitative evaluation of pore system and generates high-resolution 3D images (˜microns order). The images and data obtained by microtomography were integrated with the response obtained by nuclear logging. The results obtained by these two techniques allow the understanding of the pore-size distribution and connectivity, as well as the porosity values. Both techniques are important and they complement each other.

    The mite Allopsoroptoides galli has recently been identified parasitizing commercial chickens, São Paulo State/Brasil, causing severe dermatitis on all parts of the animal's body and a significant decline in productivity, particularly in egg production. The aim of the present study in A. galli infestation was to investigate the impact on laying hens' performance and egg quality. A total of 100 56-week-old Hy-line white laying hens were used. The birds were divided into 2 groups, with 10 replicates of 5 birds in each group. The experimental groups consisted of a non-infested group (hens free of theA. galli) and an infested group (hens presenting A. galli). The infestation with A. galli did not significantly influence feed intake but caused a significant reduction in the body weight of the hens and caused a decrease in egg production, therefore promoting worse feed conversion. The egg weight was reduced; however, the infestation did not significantly affect the internal quality of the eggs, which was measured according to the yolk color, albumen height, and Haugh units, or the quality of the shell, based on its percentage, thickness, and strength. It can be concluded that anA. galli infestation promotes a reduction in body weight, egg production, and egg weight in laying hens, therefore worsening feed conversion. PMID:26787920

    The bacteriological conditions of the coastal region of Fortaleza (Ceará, Brasil), including the coastal zones of the Ceará and Cocó rivers, were examined. The study was conducted during June, September and December 1993, and March 1994. The region was divided into two areas: (i) Direct Influence Area (DIA), consisting of 20 sampling stations located near to discharge zones of the submarine pipeline system, where collections were carried out at the surface, and (ii) Indirect Influence Area (IIA), located near to the coastal zone, including Barra do Ceará, Kartódromo, Volta de Jurema, Mucuripe, Farol and Caça e Pesca beaches, totalling 26 sampling stations. The most probable number (MPN) of both total and fecal coliforms in DIA was positive only in station number 6, near to the sewage discharge exit. The following bacteria were identified: Citrobacter sp., Enterobacter aerogenes and Escherichia coli. Kartódromo beach was contaminated throughout the sampling period. Results of total fecal MPN was essentially lower than 3.0 x 10(2) coliforms/100 ml at Caça e Pesca beach. In December, at both DIA and IIA, Salmonella was identified in several samples. In DIA, the spatial distribution for Salmonella suggests that there should be a coastal sea current from east to west along the coastline. In IIA, Salmonella was identified at Kartódromo and Farol beaches throughout the sampling period.

    The article covers the innumerable reasons given for using cloning for therapeutic and reproductive purposes. The most commonly used argument in favour of the procedure has been that of preserving human dignity, which would include the wide exercising of personal autonomy without restrictions of an ethical nature. This view is countered by questions relating to the use of the technique, namely self-determination and the loss of the integrity of the species, which would include the transformation of a generation through the production of human beings and tissues. It must also be made clear that therapeutic cloning (which is carried out through the use of stem cells) is not yet a reality in the scientific world, with the result that the procedure that is supposedly necessary, which argues in favour of the destruction of the young embryo is misleading, as are also certain discourses used to refer to the theme and the science. Criminal law, on prohibiting this practice is anticipating it becoming a reality, protecting legal rights that affect supra-individual interests, such as the destruction of the young embryo, one of the issues of concern to ADIN (Acción Directa de Inconstitucionalidad en Brasil - Direct Action on Unconstitutionality in Brazil) 3510-0.

    Macrophytes in oxbow lakes represent an important substrate for the Coleoptera. Two oxbow lakes the Rio Paranapanema were studied and the other two Rio Mogi-Guaçu, in the State de São Paulo, Brasil. In this study, there is greater similarity between the communities of Coleoptera of lakes greater connectivity with the main river channel or the difference in the species of Salvinia collected in the lakes studied interferes Coleoptera fauna that uses as substrate. A total of 9,222 specimens of Coleoptera were collected and identified in 10 families and 40 genera. The analysis MDS for abundance of Coleoptera showed the grouping of the oxbow lakes the Paranapanema River and a distancing the oxbow lakes the Mogi-Guaçu. The PERMANOVA test did not reveal any difference in the fauna between the wet and dry periods. It was concluded that the connectivity between river and lake is not decisive for the richness and abundance of aquatic fauna of Coleoptera. Therefore, the richness and abundance of aquatic Coleoptera associated vary with the species of Salvinia used as substrate. PMID:26602356

    Constituent materials of the painting "Primeira Missa no Brasil" by Sebastião Vieira Fernandes, which belongs to the Historical Museum of Santa Catarina, were analyzed by using imaging through UV-induced visible luminescence, FTIR, μ-FTIR, EDX and GC-MS with the aim of characterizing the materials and correlating them with Victor Meirelles' pigment elemental analysis reported in the literature. The images obtained under ultraviolet light showed alterations in the painting's aging process and instances of possible repainting confirmed by μ-FTIR, where characteristic bands of barium sulfate were identified. EDS analyses showed that there is a correlation between the elemental composition of pigments used by Meirelles and Fernandes, especially for lead, associated with lead white and proven by FTIR, used for giving a light tone to the paint, and found in all the analyzed samples. The GC-MS results revealed the presence of the mixture of linseed and animal oil as the main binding components with the predominance of palmitic, stearic, oleic, and linolenic acids.

    The results of analysis on a cosmic-ray induced nuclear event with the total visible energy approx. = 1300 TeV which is characterized by the central (halo) part of a strong energy concentration and the outer part of a large lateral spread are presented. The event (named as P06) was detected in the 18th two-storied emulsion chamber exposed at Chacaltaya by Brasil-Japan Collaboration. As the nuclear emulsion plates were inserted at every layer of the concerned blocks in the upper and the lower chambers together with RR- and N-type X-ray films, it is possible to study the details of the event. Some results on P06 have already been reported 1 based on the general measurement of opacity on N-type X-ray films: (1) the total energy of halo is approx. = 1000 TeV; (2) the shower transition reaches its maximum at approx. 16 cu; and (3) the radius of halo is 6.5 mm (at the level of 10 to the 6th power electrons/sq.cm.). The results in more details will be described.

    Acid mine drainage (AMD) has been identified as the main cause for outflow of acid water and radioactive/non-radioactive contaminants. AMD encompasses pyrites oxidation when water and oxygen are available. AMD was identified in uranium waste rock piles (WRPs) of Indústrias Nucleares do Brasil-Caldas facility (Brazilian uranium mine), resulting in high costs for water treatment. AMD reduction is the main challenge, and scientific investigation has been conducted to understand oxygen and water transportation within WRPs, where 222Rn is used as natural tracer for oxygen transportation. The study consists of soil radon gas mapping in the top layer of WRP4 using active soil gas pumping, radon adsorption in active charcoal and 222Rn determination using high-resolution gamma-ray spectrometry. A sampling network of 71 points was built where samples were collected at a depth of 40 cm. Soil radon gas concentration ranged from 33.7 to 1484.2 kBq m(-3) with mean concentration of 320.7±263.3 kBq m(-3). PMID:24729565

    The Mais Médicos (More Doctors) Program (PMM) was put in place in Brazil aiming to reduce inequalities in access to Primary Healthcare. Based on diverse evidence that pointed to a scenario of profound shortage of doctors in the country, one of its central thrusts was emergency provision of these professionals in vulnerable areas, referred to as the Mais Médicos para o Brasil (More Doctors for Brazil) Project. The article analyses the impact of the PMM in reducing shortage of physicians in Brazilian municipalities. To do this, it uses the Primary Healthcare Physicians Shortage Index, which identifies and measures the shortage in the periods of March 2003 and September 2015, before and after implementation of the program. The results show that there was a substantial increase in the supply of physicians in primary healthcare in the period, which helped reduce the number of municipalities with shortage from 1,200 to 777. This impact also helped reduce inequalities between municipalities, but the inequities in distribution persisted. It was also found that there was a reduction in the regular supply of doctors made by municipalities, suggesting that these were being simply substituted by the supply coming from the program. Thus, an overall situation of insecurity in care persists, reflecting the dependence of municipalities on the physician supply from the federal government.

    The aim of the present study was to evaluate the use of mini-Winkler extractor and pitfall traps as appropriate and complementary methods to sample ant communities in the phytophysiognomy mosaic in the Poconé Pantanal region, state of Mato Grosso, Brasil. Seven units were studied for landscape, located within a 25 km(2) collection area, formed by thirty 250-m transects, at 1-km intervals in a 5 × 5 km area. Five collection points were marked in each transect at 50-m intervals, totaling 150 points. A collection was made at each sampling point with mini-Winkler extractor and pitfall traps. Using the mini-Winkler extractor, 1,088 individuals were collected distributed in 20 genera and 55 species, with Solenopsis invicta Buren and Pheidole (gr. biconstricta) sp.1 as the most frequent ants. Using pitfall traps, 2,726 individuals distributed in 24 genera and 48 species were sampled and Dorymyrmex (gr. pyramicus) sp.1 and Pheidole (gr. biconstricta) sp.1 were the most frequent species. A significant difference between the methods was observed in measured species number. The Principal coordinates analysis discriminated two species groups exclusively sampled by the mini-Winkler extractor and another by the pitfall methods. Therefore, it was concluded that these methods were complementary for ant diversity inventories in the Poconé Pantanal region.

    This study proposes an alternative methodology for evaluating polymerization shrinkage of dental composites using an advanced video extensometer (AVE) system. This equipment measures the displacement between two points drawn on a tooth's wall without requiring physical contact with the tooth. By doing so, the polymerization process was monitored by the cusp deflection. This technique was used in human and bovine teeth, where the cavities were prepared under controlled conditions so that the volume of the composite used was the same in both types of teeth. After the cavity preparation, the specimens were acid etched, washed and dried, and then the adhesive was applied and polymerized. The composite was then inserted into the cavity. Polymerization was performed with two different light polymerizing units (LD Max and Optilight Max - Gnatus do Brasil), and the displacement curve of the tooth cusp was recorded for a period of 400 s. After a statistical analysis, it was concluded that the technique was capable of evaluating shrinkage by the deflection from the cusps and that the human and bovine teeth do not react in a similar manner towards the polymerization shrinkage of composites.

    2015-05-01

    In this study multi-criteria modeling tools are applied to map the spatial distribution of drainage basin potential to pollute Barra Bonita Reservoir, São Paulo State, Brasil. Barra Bonita Reservoir Basin had undergone intense land use/land cover changes in the last decades, including the fast conversion from pasture into sugarcane. In this respect, this study answers to the lack of information about the variables (criteria) which affect the pollution potential of the drainage basin by building a Geographic Information System which provides their spatial distribution at sub-basin level. The GIS was fed by several data (geomorphology, pedology, geology, drainage network and rainfall) provided by public agencies. Landsat satellite images provided land use/land cover map for 2002. Ratings and weights of each criterion defined by specialists supported the modeling process. The results showed a wide variability in the pollution potential of different sub-basins according to the application of different criterion. If only land use is analyzed, for instance, less than 50% of the basin is classified as highly threatening to water quality and include sub basins located near the reservoir, indicating the importance of protection areas at the margins. Despite the subjectivity involved in the weighing processes, the multi-criteria analysis model allowed the simulation of scenarios which support rational land use polices at sub-basin level regarding the protection of water resources.

    The Brasil is one of the most important region in the tropics. An efficient management in energy use and production in this state of Rio de Janeiro could be an excellent model to others development regions in the tropics. In 1994, the State of the Rio de Janeiro represented around 13 millions of inhabitants, an economy of 42 billions US$ (gross national products), the biggest brazilian producer in petroleum and natural gas and a large market to energy products (electric power and fossil fuels). This state was responsible for 8.6 millions tonnes of carbon in CO2 emissions in 1994, issue to combustion of petroleum products (65.9%), coal (27.8%), natural gas (3.7%), charcoal and fuelwood (2.6%). The principals responsibles to these carbon emissions are the industrial activities (40%), the transport (35.7%) and energy production (12%). The main objectives of this work are analyze the carbon emissions in energy production and use in Rio de Janeiro between 1980 and 1994, the possibilities to reduction this amount and the perspectives to renewable energy.

    1991-09-01

    Brazil is a country of vast natural resources, including numerous uranium deposits. In support of the country`s nuclear power program, Brazil has developed the most active uranium industry in South America. Brazil has one operating reactor (Angra 1, a 626-MWe PWR), and two under construction. The country`s economic challenges have slowed the progress of its nuclear program. At present, the Pocos de Caldas district is the only active uranium production. In 1990, the Cercado open-pit mine produced approximately 45 metric tons (MT) U{sub 3}O{sub 8} (100 thousand pounds). Brazil`s state-owned uranium production and processing company, Uranio do Brasil, announced it has decided to begin shifting its production from the high-cost and nearly depleted deposits at Pocos de Caldas, to lower-cost reserves at Lagoa Real. Production at Lagoa Real is schedules to begin by 1993. In addition to these two districts, Brazil has many other known uranium deposits, and as a whole, it is estimated that Brazil has over 275,000 MT U{sub 3}O{sub 8} (600 million pounds U{sub 3}O{sub 8}) in reserves.

    The Cana Brava complex is the northernmost of three layered complexes outcropping in the Goiás state (central Brasil). New field and geochemical evidences suggest that Cana Brava underwent hyper- to subsolidus deformation during its growth, acquiring a high-temperature foliation that is generally interpreted as the result of a granulite-facies metamorphic event. The increase along the stratigraphy of the incompatible elements abundances (LREE, Rb, Ba) and of the Sr isotopic composition, coupled with a decrease in ɛNd(790), indicate that the complex was contaminated by the embedded xenoliths from the Palmeirópolis Sequence. The geochemical data suggest that the contamination occurred along the entire magma column during the crystallization of the Upper Mafic Zone, with in situ variations determined by the abundance and composition of the xenoliths. These features of the Cana Brava complex point to an extremely similarity with the Lower Sequence of the most known Niquelândia intrusion (the central of the three complexes). This, together with the evidences that the two complexes have the same age (c.a. 790 Ma) and their thickness and units decrease northwards suggests that Cana Brava and Niquelândia are part of a single giant Brasilia body grown through several melt impulses.

  4. A correlação índice espectral vs. luminosidade em QSOs e suas implicações

    Estudos de variabilidade de núcleos ativos já demonstraram ser comum o fato de seu contínuo óptico/UV tornar-se mais "duro" à medida que a luminosidade aumenta. Essa tendência ocorre tanto de forma individual quanto global, e pode ter implicações importantes (1) para estudos fotométricos de variabilidade conduzidos numa banda fixa no referencial do observador, comparando objetos a diferentes redshifts, e (2) no cálculo da correção K, com consequente impacto na determinação de massas de buracos negros e bojos de galáxias hospedeiras (através da relação de Magorrian). Confirmo aqui as correlações positivas entre o índice espectral e a luminosidade óptica, utilizando dados espectroscópicos de 11 QSOs monitorados no Brasil e no Chile, durante ~2 anos. O estudo é complementado com parâmetros extraídos de espectros e de dados fotométricos públicos de quasares. Destaco ainda as diferenças observadas em tais correlações para objetos do tipo radio-loud e radio-quiet. Este projeto é financiado pelo I. Milênio/CNPq.

    Saurian malaria species which produce schizonts smaller than normal erythrocyte nuclei, with 4-8 merozoietes and gametocytes equal to or smaller than erythrocyte nuclei in size, parasitizing hosts of the lizard families Scincidae, Iguanidae and Teiidae in the Neotropics are considered to be Plasmodium minasense Carini and Rudolph, 1912. Subspecific designations are given to distinctive populations parasitizing different host species: P. minasense minasense is recognized from the type host, Mabuya mabouya of Brasil; P. minasense carinii Leger and Mouzels, 1917 from Iguana iguana of coastal South America; P. minasense anolisi subsp. nov. from Anolis limifrons of Panama; P. minasense capitoi subsp. nov. from Anolis capito of Panama; P. minasense plicae subsp. nov. from Plica umbra of Guyana; P. minasense tegui subsp. nov. from Tupinambis teguixin of Venezuela; and P. minasense diminutivum Telford, 1973, new combination, from Ameiva ameiva of Panama. Plasmodium rhadinurum Thompson and Huff, 1944 is recognized as a distinct species at present on the basis of possessing schizonts of different shape, asexual stages with filamentous projections in most portions of its range, and larger gametocytes, as well as apparent sympatry with P. minasense carinii in some areas.

    The bacteriological conditions of the coastal region of Fortaleza (Ceará, Brasil), including the coastal zones of the Ceará and Cocó rivers, were examined. The study was conducted during June, September and December 1993, and March 1994. The region was divided into two areas: (i) Direct Influence Area (DIA), consisting of 20 sampling stations located near to discharge zones of the submarine pipeline system, where collections were carried out at the surface, and (ii) Indirect Influence Area (IIA), located near to the coastal zone, including Barra do Ceará, Kartódromo, Volta de Jurema, Mucuripe, Farol and Caça e Pesca beaches, totalling 26 sampling stations. The most probable number (MPN) of both total and fecal coliforms in DIA was positive only in station number 6, near to the sewage discharge exit. The following bacteria were identified: Citrobacter sp., Enterobacter aerogenes and Escherichia coli. Kartódromo beach was contaminated throughout the sampling period. Results of total fecal MPN was essentially lower than 3.0 x 10(2) coliforms/100 ml at Caça e Pesca beach. In December, at both DIA and IIA, Salmonella was identified in several samples. In DIA, the spatial distribution for Salmonella suggests that there should be a coastal sea current from east to west along the coastline. In IIA, Salmonella was identified at Kartódromo and Farol beaches throughout the sampling period. PMID:9608520

    Abstract We studied the amphibian community of the Private Reserve of Natural Heritage (RPPN) Serra Bonita, an area of 20 km2 with steep altitudinal gradients (200–950 m a.s.l.) located in the municipalities of Camacan and Pau-Brasil, southern Bahia State, Brazil. Data were obtained at 38 sampling sites (including ponds and transects within the forest and in streams), through active and visual and acoustic searches, pitfall traps, and opportunistic encounters. We recorded 80 amphibian species distributed in 15 families: Aromobatidae (1), Brachycephalidae (3), Bufonidae (4), Centrolenidae (2), Ceratophryidae (1), Craugastoridae (7), Eleutherodactylidae (2), Hemiphractidae (2), Hylidae (42), Hylodidae (1), Leptodactylidae (7), Microhylidae (3), Siphonopidae (1), Odontophrynidae (3) and Pipidae (1). Species richness was positively correlated with monthly rainfall. Near 36% of the species were found in strictly forest environments, 15% are endemic to Bahia State and 77.2% are endemic to the Atlantic Forest biome. The large species diversity of this small area, the high degree of endemism and the taxonomic and biogeographic significance turn the Serra Bonita mountain into a hotpoint for amphibians within Brazil’s Atlantic Forest hotspot.

    Tissue samples from nine red foxes (four samples of striated muscle tissue and five samples of heart tissue) that originated from the Michalovce district (Slovakia), an area with endemic occurrence of canine babesiosis were examined by PCR method using primers amplifying a fragment of the 18S rRNA spanning the V4 region of Babesia and Theileria. An unexpected determination of 450 bp DNA fragment of Hepatozoon canis was found in four samples. Partial sequences of the 18S rRNA gene from the H. canis showed 100% similarity with the sequence from Brasil isolate of H. canis from a pampas fox (Pseudalopex gymnocercus) (AY471615) as well as from a fox in Spain (AY150067) and from a dog in Brazil (AY864677). In the present study, we report the first PCR detection of Hepatozoon canis in a naturally infected red fox from Slovakia, a Rhipicephalus sanguineus-free region. We assume that the infection was spread by infected R. sanguineus that might have been brought to Slovakia by travelers, by golden jackals, or by foxes migrating because of expansion of golden jackals and environmental and climate changes.

    The South Atlantic Anomaly (SAA) refers to the area where the Earth's inner Van Allen radiation belt comes closest to the Earth's surface, leading to increased levels of cosmic radiation at lower altitudes than elsewhere over the surface. A strong effect of the SAA on the quality of Jason-1 DORIS (Doppler Orbitography and Radiopositioning Integrated by Satellite) observations is well known and several relevant analyses has been published. However, the significant effect of SAA on the other DORIS satellites has not been known. The goal of the paper is to bring a detail analyses of possible SAA effect on the SPOT -2,4,5 and the Envisat DORIS observations. The resulted zenithal total delay (ZTD), oscillator frequency offset and station coordinates, estimated using single-satellite data processing, are presented and discussed. A DORIS-GNSS ZTD comparison is done in addition. A significant bias was detected when processing SPOT-5 data for South American stations Santiago in Chille, Cachoeira Paulista in Brasil and Arequipa in Peru. Even if the detected bias is much lower than in case of Jason-1 and doesn't degrade the DORIS observation so strongly, possible future approach of the SPOT-5 SAA effect elimination (model of oscillator behavior or exclusion of the most corrupted observations) could improve the DORIS solutions. A comparable level of SAA-related effect was not detected for any other of the analyzed satellites.

    Macrophytes in oxbow lakes represent an important substrate for the Coleoptera. Two oxbow lakes the Rio Paranapanema were studied and the other two Rio Mogi-Guaçu, in the State de São Paulo, Brasil. In this study, there is greater similarity between the communities of Coleoptera of lakes greater connectivity with the main river channel or the difference in the species of Salvinia collected in the lakes studied interferes Coleoptera fauna that uses as substrate. A total of 9,222 specimens of Coleoptera were collected and identified in 10 families and 40 genera. The analysis MDS for abundance of Coleoptera showed the grouping of the oxbow lakes the Paranapanema River and a distancing the oxbow lakes the Mogi-Guaçu. The PERMANOVA test did not reveal any difference in the fauna between the wet and dry periods. It was concluded that the connectivity between river and lake is not decisive for the richness and abundance of aquatic fauna of Coleoptera. Therefore, the richness and abundance of aquatic Coleoptera associated vary with the species of Salvinia used as substrate.

    SAOZ is a small remote sensing instrument looking at solar occultation during the ascent of the balloon and during sunset (or sunrise) from floating altitude. It is a UV-visible spectrometer measuring O3 and NO2 and in its enhanced UV version, BrO. The vertical profiles, retrieved by onion peeling, have a typical vertical resolution of 1.5 km. Since the launch of ODIN in 2001 seventeen SAOZ balloon flights have been performed at various latitudes and seasons: a - nine flights at mid-latitudes in summer and autumn from southern France (43°N) within the BALODIN/CNES and ESABC programs and from Vanscoy (52°N) in Saskatchevan within the MANTRA 2002 and MANTRA 2004 Canadian campaigns; b - four flights in the Arctic from Kiruna in Sweden (67°N) in winter, inside and outside the polar vortex as well as in summer; c - and finally four flights in the tropics from Bauru in Brasil (22°S) in summer within the pre-HIBISCUS and HIBISCUS/VINTERSOL EU project. Comparison with coincident OSIRIS/ODIN, SCIAMACHY/ENVISAT and GOMOS/ENVISAT ozone, NO2 and BrO profiles are presented.

    The backshore zone is transitional environment strongly affected by ocean, air and sand movements. On dissipative beaches, the formation of ephemeral dunes over the backshore zone plays significant contribution in the beach morphodynamics and sediment budget. The aim of this work is to describe a novel method to identify ephemeral dunes in the backshore region and to discuss their morphodynamic behavior. The beach morphology is identified using Argus video imagery, which reveals the behavior of morphologies at Cassino Beach, Rio Grande do Sul, Brasil. Daily images from 2005 to 2007, topographic profiles, meteorological data, and sedimentological parameters were used to determine the frequency and pervasiveness of these features on the backshore. Results indicated that coastline orientation relative to the dominant NE and E winds and the dissipative morphological beach state favored aeolian sand transport towards the backshore. Prevailing NE winds increase sand transportation to the backshore, resulting in the formation of barchans, transverse, and barchanoid-linguiod dunes. Precipitation inhibits aeolian transport and ephemeral dune formation and maintains the existing morphologies during strong SE and SW winds, provided the storm surge is not too high.

    The objective of this study was to describe the circumstances that promoted the implementation of the new Program for Action Against Tuberculosis in Brazil (Programa de Ação na Luta contra a Tuberculose no Brasil) and discuss the strategies used by registered nurses from the Santa Maria State Hospital, Guanabara State, to adjust nursing care to the new program against tuberculosis. This was performed through document research, interviews, and statements from nurses working at the time of the reorganization. Documents were analyzed based on the concepts of habitus, field, and symbolic power by Pierre Bourdieu, and included written and oral documents as well as secondary sources. The reorganization of the nursing service was performed under the leadership of a nurse whose symbolic capital assigned power and prestige to implement the necessary changes. It is concluded that the work of that nurse made it possible to implement the new program and contributed to establishing the position and importance of the registered nurse in providing care to individuals with tuberculosis, for prevention and cure.

    This paper analyzes the profile of the Brazilian output in the field of multiple sclerosis from 1981 to 2004. The search was conducted through the MEDLINE and LILACS databases, selecting papers in which the term "multiple sclerosis" was defined as the main topic and "Brazil" or "Brasil" as others. The data were analyzed regarding the themes, the state in Brazil and institution where the papers were produced, the journals where the papers were published, journal's impact factor, and language. The search disclosed 141 documents (91 from MEDLINE and LILACS, and 50 from LILACS only) published in 44 different journals (23 of them MEDLINE-indexed). A total of 111 documents were produced by 17 public universities, 29 by 3 private medical schools and 1 by a non-governmental organization. There were 65 original contributions, 37 case reports, 20 reviews, 6 PhD dissertations, 5 guidelines, 2 validation studies, 2 clinical trials, 2 chapters in textbooks, 1 Master of Science thesis, and 1 patient education handout. The journal impact factor ranged from 0.0217 to 6.039 (median 3.03). Of 91 papers from MEDLINE, 65 were published by Arquivos de Neuro-Psiquiatria. More than 90% of the papers were written in Portuguese. São Paulo was the most productive state in the country, followed by Rio de Janeiro, Minas Gerais and Paraná. Eighty-two percent of the Brazilian output came from the Southeastern region.

    In this study, we identified the phlebotomine sandfly vectors involved in the transmission of American Cutaneous Leishmaniasis (ACL) in Assis Brasil, Acre, Brazil, which is located on the Brazil-Peru-Bolivia frontier. The genotyping of Leishmania in phlebotomines was performed using polymerase chain reaction (PCR) and PCR-restriction fragment length polymorphism. A total of 6,850 sandflies comprising 67 species were captured by using CDC light traps in rural areas of the municipality. Three sandfly species were found in the state of Acre for the first time: Lutzomyia georgii, Lu. complexa and Lu. evangelistai. The predominant species was Lu. auraensis/Lu. ruifreitasi and Lu. davisi (total 59.27%). 32 of 368 pools were positive for the presence of Leishmania DNA (16 pools corresponding to Lu. davisi, and 16 corresponding to Lu. auraensis/Lu. ruifreitasi), with a minimal infection prevalence of 1.85% in Lu. davisi and 2.05% in Lu. auraensis/Lu. ruifreitasi. The Leishmania species found showed maximum identity with L. (Viannia) guyanensis and L. (V.) braziliensis in both phlebotomine species. Based on these results and similar scenarios previously described along the Brazil/Peru/Bolivia tri-border, the studied area must take into consideration the possibility of Lu. davisi and Lu. auraensis/Lu. ruifreitasi as probable vectors of ACL in this municipality.

    The most common modeling approaches to understanding incidence, prevalence and control of chronic diseases in populations, such as statistical regression models, are limited when it comes to dealing with the complexity of those problems. Those complex adaptive systems have characteristics such as emerging properties, self-organization and feedbacks, which structure the system stability and resistance to changes. Recently, system science approaches have been proposed to deal with the range, complexity, and multifactor nature of those public health problems. In this paper we applied a multilevel systemic approach to create an integrated, coherent, and increasingly precise conceptual framework, capable of aggregating different partial or specialized studies, based on the challenges of the Longitudinal Study of Adult Health – ELSA-Brasil. The failure to control blood pressure found in several of the study's subjects was discussed, based on the proposed model, analyzing different loops, time lags, and feedback that influence this outcome in a population with high educational level, with reasonably good health services access. We were able to identify the internal circularities and cycles that generate the system’s resistance to change. We believe that this study can contribute to propose some new possibilities of the research agenda and to the discussion of integrated actions in the field of public health. PMID:26171854

    The year 2004 signals the 400th anniversary of the birth of count Mauricio of Nassau, an important character in the history of Brazil. The present text is related to the period of Dutch domination in Pernambuco. The article attempts to rescue the beginnings of Astronomy study in the South hemisphere. Therefore, we idealized a dramatization of a fictitious interview with German astronomer Georg Marcgrave, who was the constructor of the first astronomical observatory in this hemisphere and the author of the first systematic astronomical observations using telescopes in this side of the world. Our "conversation" with Marcgrave is idealized in the old Recife scenario, a place where he lived in Mauricio of Nassau's period and gathers some fellow teachers who love the teaching of Astronomy. The story, this way, is reported in a possibly light and funny atmosphere. Nevertheless, the conceptual and historical framework presented is based on reliable bibliographical sources pointed out at the end of the text. The sources range from the original book of that scientist, in which a solar eclipse is reported, passing through some other classical texts, such as that of Professor Juliano Moreira, up to more recent sources such as the very influential work of professor John North. Other influential texts about the Dutch period in Brazil, such as the classical works of Charles Boxer, Bouman and Boogaart, among others, are also used in the construction of this pedagogical dramatization, which involves an interesting chapter of the history of Astronomy.

    Esta investigación tiene como objetivo investigar el efecto que la disolución de las uniones consensuales tiene en los niveles de soltería que proporciona el Censo de Población, niveles derivados de la variable estado civil. Para ello comparamos los datos censales con los de la Encuestas de Demografía y Salud (de ahora en adelante DHS) en aquellos países y años para los que disponemos de ambas fuentes en el mismo año o años adyacentes (Bolivia, Brasil, Colombia y Perú). Los resultados muestran claramente que las proporciones de nunca unidas derivadas de la variable censal ’Estado civil’ son sistemáticamente más elevadas que las estimadas a partir de las DHS. La razón de esta sobreestimación obedece al hecho de que personas que estuvieron en unión libre en el pasado se declaran solteras en el momento del Censo. La elevada proporción de mujeres solteras que tienen hijos según el Censo es una prueba de ello y a su vez una solución efectiva para corregir el sesgo. PMID:25593515

    Introduccion. El actual brote epidemico por virus Zika se inicio en 2015 y en la actualidad afecta a 31 paises y territorios en America. Se revisan los aspectos epidemiologicos y clinicos asociados con la infeccion por virus Zika. Desarrollo. Desde 2007, 55 paises de America, Asia, Africa y Oceania han detectado transmision local del virus. La actual epidemia ha afectado a casi 1,5 millones de personas en Brasil. El 80% de los casos son asintomaticos. La enfermedad por virus Zika cursa con fiebre, exantema maculopapular, artralgias y conjuntivitis no purulenta. Los sintomas suelen ser autolimitados y duran una semana. Se ha descrito un aumento de la incidencia de los casos de microcefalia, lesiones retinianas y sindrome de Guillain-Barre asociados con el virus Zika. El sindrome de Guillain-Barre asociado al Zika en la Polinesia es una variante axonal motora pura. El ARN del virus Zika se ha identificado en muestras de tejido cerebral, placenta y liquido amniotico de niños con microcefalia y en perdidas fetales de mujeres infectadas por Zika durante el embarazo. Se recomienda realizar la prueba de reaccion en cadena de la polimerasa mediante transcriptasa inversa para detectar ARN virico y pruebas serologicas (IgM ELISA y anticuerpos neutralizantes) para confirmar una infeccion por Zika. El diagnostico diferencial incluye la infeccion por virus dengue y chikungunya. Conclusiones. Existe un conocimiento limitado sobre los mecanismos patogenicos implicados y las consecuencias a largo plazo de la infeccion por virus Zika en adultos y recien nacidos.

    2015-05-01

    In this study multi-criteria modeling tools are applied to map the spatial distribution of drainage basin potential to pollute Barra Bonita Reservoir, São Paulo State, Brasil. Barra Bonita Reservoir Basin had undergone intense land use/land cover changes in the last decades, including the fast conversion from pasture into sugarcane. In this respect, this study answers to the lack of information about the variables (criteria) which affect the pollution potential of the drainage basin by building a Geographic Information System which provides their spatial distribution at sub-basin level. The GIS was fed by several data (geomorphology, pedology, geology, drainage network and rainfall) provided by public agencies. Landsat satellite images provided land use/land cover map for 2002. Ratings and weights of each criterion defined by specialists supported the modeling process. The results showed a wide variability in the pollution potential of different sub-basins according to the application of different criterion. If only land use is analyzed, for instance, less than 50% of the basin is classified as highly threatening to water quality and include sub basins located near the reservoir, indicating the importance of protection areas at the margins. Despite the subjectivity involved in the weighing processes, the multi-criteria analysis model allowed the simulation of scenarios which support rational land use polices at sub-basin level regarding the protection of water resources.

    ABSTRACT Objective: To determine the prevalence of low back pain in children and its relationship with gender, age, exercise practice and sedentary activities (time on TV and on computer and/or video game). Methods: We conducted a cross-sectional study with a sample of 1,461 students, being 754 males and 707 females enrolled in the 5th to 8th grades of all five local elementary schools of urban Ourinhos, SP, Brasil, aged 10-14 years old, from whom sociodemographic data, time spent on sedentary activities such as TV and computer and/or video game were collected. We conducted a descriptive, bivariate and multivariate binary logistic regression. Results: The results showed that the prevalence of low back pain in the sample was 18.5%, being 15.5% in boys and 21.6% in girls. Low back pain was associated to the female gender, age range between 12-14 years and the habit of watching TV more than three times a week and over 3 hours per day. Conclusion: The students analyzed showed high prevalence of low back pain related to gender, age and habit of watching TV. Appropriate interventions should be implemented to reduce the occurrences of back pain in schoolchildren. Level of Evidence III, Cross Sectioning. PMID:26981028

    The most common modeling approaches to understanding incidence, prevalence and control of chronic diseases in populations, such as statistical regression models, are limited when it comes to dealing with the complexity of those problems. Those complex adaptive systems have characteristics such as emerging properties, self-organization and feedbacks, which structure the system stability and resistance to changes. Recently, system science approaches have been proposed to deal with the range, complexity, and multifactor nature of those public health problems. In this paper we applied a multilevel systemic approach to create an integrated, coherent, and increasingly precise conceptual framework, capable of aggregating different partial or specialized studies, based on the challenges of the Longitudinal Study of Adult Health - ELSA-Brasil. The failure to control blood pressure found in several of the study's subjects was discussed, based on the proposed model, analyzing different loops, time lags, and feedback that influence this outcome in a population with high educational level, with reasonably good health services access. We were able to identify the internal circularities and cycles that generate the system's resistance to change. We believe that this study can contribute to propose some new possibilities of the research agenda and to the discussion of integrated actions in the field of public health. PMID:26171854

    The mite Allopsoroptoides galli has recently been identified parasitizing commercial chickens, São Paulo State/Brasil, causing severe dermatitis on all parts of the animal's body and a significant decline in productivity, particularly in egg production. The aim of the present study in A. galli infestation was to investigate the impact on laying hens' performance and egg quality. A total of 100 56-week-old Hy-line white laying hens were used. The birds were divided into 2 groups, with 10 replicates of 5 birds in each group. The experimental groups consisted of a non-infested group (hens free of theA. galli) and an infested group (hens presenting A. galli). The infestation with A. galli did not significantly influence feed intake but caused a significant reduction in the body weight of the hens and caused a decrease in egg production, therefore promoting worse feed conversion. The egg weight was reduced; however, the infestation did not significantly affect the internal quality of the eggs, which was measured according to the yolk color, albumen height, and Haugh units, or the quality of the shell, based on its percentage, thickness, and strength. It can be concluded that anA. galli infestation promotes a reduction in body weight, egg production, and egg weight in laying hens, therefore worsening feed conversion.

    This work is intended to illustrate the possibilities offered by the CoRoT satellite observations to study the different instability strips, and through them, physical processes and specific features of stellar interiors. The CoRoT space mission {(Baglin A. et al. 2002)}, launched on December 27th 2006, has been developped and is operated by CNES, with the contribution of Austria, Belgium, Brasil, ESA, Germany and Spain. It enables us to observe oscillations from stars down to a noise level of less than a ppm, much lower than the limit usually obtained from the ground. During the nominal duration of the mission, about 6 long runs (˜ 150d each) and 6 short runs (˜ 20d each) will take place {(CoRoT Book, 2006)}. Only 2 long runs and 1 short run are illustrated in this study. This means that the number of available targets will have more than tripled by the end of the mission. These data might help testing the "purity" of the instability strips (i.e. the presence/absence of photometrically constant stars within) and lead to the discovery of new classes of pulsating stars {(Degroote et al 2008)}. We address this problem in the frame of the B and A main sequence stars.

    This is the third in a series of papers studying the variable stars in old globular clusters in the Large Magellanic Cloud. The primary goal of this series is to look at how the characteristics and behavior of RR Lyrae stars in Oosterhoff-intermediate systems compare to those of their counterparts in Oosterhoff-I/II systems. In this paper we present the results of our new time-series BVI photometric study of the globular cluster Reticulum. We found a total of 32 variables stars (22 RRab, 4 RRc, and 6 RRd stars) in our field of view. We present photometric parameters and light curves for these stars. We also present physical properties, derived from Fourier analysis of light curves, for some of the RR Lyrae stars. We discuss the Oosterhoff classification of Reticulum and use our results to re-derive the distance modulus and age of the cluster.

    Variations in the pulsation arrival time of five independent pulsation frequencies of the DB white dwarf EC 20058-5234 individually imitate the effects of reflex motion induced by a planet or companion but are inconsistent when considered in unison. The pulsation frequencies vary periodically in a 12.9 year cycle and undergo secular changes that are inconsistent with simple neutrino plus photon-cooling models. The magnitude of the periodic and secular variations increases with the period of the pulsations, possibly hinting that the corresponding physical mechanism is located near the surface of the star. The phase of the periodic variations appears coupled to the sign of the secular variations. The standards for pulsation-timing-based detection of planetary companions around pulsating white dwarfs, and possibly other variables such as subdwarf B stars, should be re-evaluated. The physical mechanism responsible for this surprising result may involve a redistribution of angular momentum or a magnetic cycle. Additionally, variations in a supposed combination frequency are shown to match the sum of the variations of the parent frequencies to remarkable precision, an expected but unprecedented confirmation of theoretical predictions.

    We present high-quality BVRI photometric data in the field of globular cluster NGC 6496 obtained with the SOAR Telescope Adaptive Module (SAM). Our observations were collected as part of the ongoing SAM commissioning. The distance modulus and cluster color excess as found from the red clump are (m - M) V = 15.71 ± 0.02 mag and E(V - I) = 0.28 ± 0.02 mag. An age of 10.5 ± 0.5 Gyr is determined from the difference in magnitude between the red clump and the subgiant branch. These parameters are in excellent agreement with the values derived from isochrone fitting. From the color-magnitude diagram we find a metallicity of [Fe/H] = -0.65 dex and hence support a disk classification for NGC 6496. The complete BVRI data set for NGC 6469 is made available in the electronic edition of the Journal.

We find an absolute magnitude of HR = 19.71 ± 0.05 mag and slope parameter of GR = -0.08 ± 0.05 for the inactive nucleus, corresponding to an effective nucleus radius of re = 0.30 ± 0.02 km, assuming an R-band albedo of pR = 0.05. We also revisit observations reported for 259P while it was active in 2008 to quantify the dust mass loss and compare the object with other known main-belt comets.

    The backshore zone is transitional environment strongly affected by ocean, air and sand movements. On dissipative beaches, the formation of ephemeral dunes over the backshore zone plays significant contribution in the beach morphodynamics and sediment budget. The aim of this work is to describe a novel method to identify ephemeral dunes in the backshore region and to discuss their morphodynamic behavior. The beach morphology is identified using Argus video imagery, which reveals the behavior of morphologies at Cassino Beach, Rio Grande do Sul, Brasil. Daily images from 2005 to 2007, topographic profiles, meteorological data, and sedimentological parameters were used to determine the frequency and pervasiveness of these features on the backshore. Results indicated that coastline orientation relative to the dominant NE and E winds and the dissipative morphological beach state favored aeolian sand transport towards the backshore. Prevailing NE winds increase sand transportation to the backshore, resulting in the formation of barchans, transverse, and barchanoid-linguiod dunes. Precipitation inhibits aeolian transport and ephemeral dune formation and maintains the existing morphologies during strong SE and SW winds, provided the storm surge is not too high. PMID:27598845

    Zoos may play an important role in conservation when they maintain and breed large numbers of animals that are threatened with extinction. Bird conservation is in a privileged situation owing to the extensive biological information available about this class. Annual inventories produced by the "Sociedade de Zoológicos do Brasil" in the years 1981, 1990, 2000, and 2005 were analyzed. Variables, such as the number of zoos per geographic region; number of birds held; number of bird species in each IUCN threat category; number of exotic and native bird species; number of potentially breeding bird species; number of bird species in each order; and number of threatened bird species breeding, were analyzed. Brazilian zoos kept more than 350 bird species. The number of bird species and specimens held by the Brazilian Zoos increased from 1981 to 2000, but decreased in 2005. The same pattern was observed for the number of species in each IUCN threat category. Results showed that the potential of the Brazilian zoos in bird conservation needs to be enhanced because they maintain threatened species but do not implement systematic genetic, reproductive, or behavioral management protocols for most species.

    This study proposes an alternative methodology for evaluating polymerization shrinkage of dental composites using an advanced video extensometer (AVE) system. This equipment measures the displacement between two points drawn on a tooth's wall without requiring physical contact with the tooth. By doing so, the polymerization process was monitored by the cusp deflection. This technique was used in human and bovine teeth, where the cavities were prepared under controlled conditions so that the volume of the composite used was the same in both types of teeth. After the cavity preparation, the specimens were acid etched, washed and dried, and then the adhesive was applied and polymerized. The composite was then inserted into the cavity. Polymerization was performed with two different light polymerizing units (LD Max and Optilight Max - Gnatus do Brasil), and the displacement curve of the tooth cusp was recorded for a period of 400 s. After a statistical analysis, it was concluded that the technique was capable of evaluating shrinkage by the deflection from the cusps and that the human and bovine teeth do not react in a similar manner towards the polymerization shrinkage of composites.

    Human seroprevalence of Flavivirus was determined by hemagglutination inhibition tests on 479 sera from Misiones and 49 from Corrientes provinces. Paraná and Uruguay river bank communities from Argentina and neighbouring countries carry out frequent traffic across the rivers. With the aim of searching for a possible introduction of Dengue virus from Brasil or/and Paraguay, reactivity among people from Paraná and Uruguay river communities was compared with those from mountain communities. Two sera from Ituzaingó (Corrientes Province) were positive for Dengue 2. In Misiones, 3 sera from Oberá and 2 from Montecarlo were reactive for Dengue 2 and 1 serum from Puerto Iguazú was reactive for Dengue 1. Seroprevalence among the river population was significatively higher than among the mountain population. Likewise, populations on Paraná river showed more positive sera than those on Uruguay river; 54% of the samples possessed titers for SLE virus higher than for Dengue or Yellow fever. Anti-alphavirus (EEE and WEE) antibodies tested in sera from Misiones people showed a complementary distribution pattern to flavivirus. Seroprevalence of anti-alphavirus antibodies was higher in the mountain than in the river populations.

    The aim of the present study was to investigate the seroprevalence to Flavivirus, in young people living in risk areas. We analyzed 189 human sera from 3 towns in the Province of Formosa. This area corresponds to the border that limits Brasil and Paraguay and the aim was to search for a possible introduction of Dengue and Yellow Fever from these countries. Serological tests such as haemagglutination inhibition (HI), complement fixation (CF) and neutralization (NT) were performed using St. Louis encephalitis (SLE), Bussuquara, Ilheus, Yellow fever and dengue 1 and 2 viruses. No definite evidence for HI antibodies to dengue and Ilheus was obtained. One serum cross-reacted only with yellow fever and two sera only for Bussuquara by the HI test. Only one serum was confirmed to be positive for Bussuquara by NT test. A total of 22 sera from 189 were positive for SLE by the HI test and 40 were also reactive by the NT test. The seroprevalence measured by HI and NT antibodies was similar in the three departments studied. These results show that SLE virus is present in the North of Argentina with an important value of prevalence so that this agent could play an important role in the febrile infections not virologically confirmed.

    We present results of comparisons between consanguineous and control couples and their children in Southern Brasil. Multiple regression, t-test and chi 2 analyses were applied to the data. The following variables were investigated; Parents: structure of first cousin marriages, latitude and longitude of birthplaces, cohabitation time, rurality, marriage age, occupation, number of liveborn children, and frequency of twinning. Schoolchildren: clinical data as classified into 24 discontinuous traits, each one subdivided into two categories (number and severity), and seven continuous traits (weight, height, pulse rate, respiratory rate, systolic pressure, diastolic pressure, and temperature); nutrition indices and biotype; family names; intelligence tests and school performance; birth order, age, hair color, hair type, eye color, and skin color; twinning in the sibship, and infant mortality among sibs of the propositi. Our study showed a) nonrandomness of consanguineous marriages as detected on structural, racial, geographical, and temporal levels; b) a heavy mutational load of about 1.5 lethons acting on infant mortality; c) no inbreeding effect on morbidity in general (with a possible exception of "ear morbidity", including hearing deficit); d) a modest inbreeding depression on height (a decrease of 2 cm with an increase of 10% of inbreeding); 3) a suggestion of inbreeding depression on "intelligence".

    Brazil is the only country in the world to propose a universal health care system with the aim of guaranteeing delivery of all levels of health care, free of charge, to a population of over 200 million inhabitants by means of a unified health system ("Sistema Único de Saúde" [SUS]). The national policy of oral health, also known as Smiling Brazil ("Brasil Sorridente"), was implemented in 2004. Oral health was designated as 1 of the 4 priority areas of the SUS, transforming oral health care in Brazil, with the objective that the SUS achieve the integrality of care envisaged at its creation. The aim of this article is to share part of this experience in order to prompt reflection about the inclusion of oral health care in other health care systems around the world. The most significant results of Smiling Brazil can be seen in 3 areas: (1) oral health epidemiological indicators, (2) financial investment and professional development, and (3) the building of an oral health care network throughout the 10 y of the policy. The "Discovery!" article presented here portrays 10 y of evolution; however, it is important to point out that this is a process undergoing construction and that the oral health care network needs to be further expanded, refined, and solidified so that over time and through changes in the political parties in power, Smiling Brazil prevails as a perennial policy and not merely an action by a single government.

    Satellite images have great educational potential for teaching on environmental issues and can promote the motivation of young people to enter careers in natural science and technology. Due to the importance and ubiquity of remote sensing in science, industry and the public, the use of satellite imagery has been included into many school curricular in Germany. However, its implementation into school practice is still hesitant, mainly due to lack of teachers' know-how and education materials that align with the curricula. In the project "Space4Geography" a web-based learning platform is developed with the aim to facilitate the application of satellite imagery in secondary school teaching and to foster effective student learning experiences in geography and other related subjects in an interdisciplinary way. The platform features ten learning modules demonstrating the exemplary application of original high spatial resolution remote sensing data (RapidEye and TerraSAR-X) to examine current environmental issues such as droughts, deforestation and urban sprawl. In this way, students will be introduced into the versatile applications of spaceborne earth observation and geospatial technologies. The integrated web-based remote sensing software "BLIF" equips the students with a toolset to explore, process and analyze the satellite images, thereby fostering the competence of students to work on geographical and environmental questions without requiring prior knowledge of remote sensing. This contribution presents the educational concept of the learning environment and its realization by the example of the learning module "Deforestation of the rainforest in Brasil".

    The author has based his work "Retroperitoneals tumors in infancy and childhood" in 65 cases observed at "Hospital Martagao Gesteira", Salvador, Bahia, Brasil. 32 of the retroperitoneals tumors, either intrarenals or extrarenals, observed in infancy and childhood were Wilm's tumor, 22 neuroblastoma, 5 hydronephrosis, 2 multicystic kidney, 1 policystic kidney, 2 pancreatic cyst and 1 biliar cyst. Wilm's tumor had the highest incidence - 32 cases (49,2%); neuroblastoma was in the second place in incidence - 22 (33,8%) of the 65 cases of retroperitoneals tumors studied, were neuroblastoma. As registered by the author in previous paper, the neuroblastoma, on contrary of what is established in the specialized literature, not was: the most frequent abdominal tumors, in infancy and childhood, neither it was also the abdominal pediatric tumor which could match Wilm's tumor in incidence. The plain X ray film of the abdomen, the Excretory Urography, the Cavography and Arteriography, the Radiological Examination of the Stomach and Duodenum, of the Small Intestine and the Colons, contribute in a very important way to establish the topography (retro or intraperitoneal) of the pediatric abdominal tumors. The author emphasizes that the plain X ray film of the abdomen supply important elements for the conclusion concerning the localization of abdominal tumors, from the observation of a simple criterion - the retroperitoneals tumors obliterate the border of kidney, because they are placed in the same plan of the kidney, data which is not pointed out sufficiently by the authors who have studied the subject.

    The successful qualification flight of the VSB-30 occurred in October 23, 2004, in Alcantara, Brasil, after a long campaign mainly due to adverse wind conditions. In the wake of this flight, lies the renewed hope to keep the European sounding rocket microgravity program alive. This paper presents technical aspects of the main subsystems, the rocket and flight results. In the subsystem level, the results of the three firing tests of the S31 motor are presented together with the expected flight trust curve. The second stage fins and the payload service module were also important develoments that required extensive ground test qualification. The use of the ground qualified thrusters for the VLS-1 spin-up system proved to be a good asset for the VSB-30 spin up system. The second stage tail can and the payload adapter have large structural margins and did not undergo qualification tests. In the system level, the main tasks were to predict the trajectory parameters and establish the flight safety procedure. The payload service module was equipped with 3-axis gyros, accelerometers, vibration accelerometers, a GPS receiver and temperature sensors that provided a wealth of information on the flight dynamics, trajectory parameters and the mechanical environment. All expected and unexpected results are discussed.

Para compor esse esboço histórico, utilizamos, principalmente, livros didáticos, regulamentos, decretos e leis responsáveis pelas organizações dos conteúdos oferecidos e das carreiras dos responsáveis pela disciplina. Na análise do material empregado, investigamos a presença de concepções filosóficas e científicas, que podem ter norteado os conteúdos disciplinares. Não realizamos nenhuma comparação com o ensino de astronomia em outros países. Concluímos mostrando que o estudo de astronomia, durante o período monárquico, foi mais direcionado para a formação d engenheiros do que astrônomos. Gostaríamos de observar que o presente artigo não tem a pretensão de abordar o assunto de maneira completa e detalhada.

    K-band spectra are presented for a sample of 39 Spitzer Infrared Spectrograph (IRS) SAGE-Spec sources in the Large Magellanic Cloud. The spectra exhibit characteristics in very good agreement with their positions in the near-infrared—Spitzer color-magnitude diagrams and their properties as deduced from the Spitzer IRS spectra. Specifically, the near-infrared spectra show strong atomic and molecular features representative of oxygen-rich and carbon-rich asymptotic giant branch stars, respectively. A small subset of stars was chosen from the luminous and red extreme ``tip" of the color-magnitude diagram. These objects have properties consistent with dusty envelopes but also cool, carbon-rich ``stellar" cores. Modest amounts of dust mass loss combine with the stellar spectral energy distribution to make these objects appear extreme in their near-infrared and mid-infrared colors. One object in our sample, HV 915, a known post-asymptotic giant branch star of the RV Tau type, exhibits CO 2.3 μm band head emission consistent with previous work that demonstrates that the object has a circumstellar disk.

    To improve the statistics of hierarchical multiplicity, secondary components of wide nearby binaries with solar-type primaries were surveyed at the SOAR telescope for evaluating the frequency of subsystems. Images of 17 faint secondaries were obtained with the SOAR Adaptive Module that improved the seeing; one new 0.''2 binary was detected. For all targets, photometry in the g', i', z' bands is given. Another 46 secondaries were observed by speckle interferometry, resolving 7 close subsystems. Adding literature data, the binarity of 95 secondary components is evaluated. We found that the detection-corrected frequency of secondary subsystems with periods in the well-surveyed range from 103 to 105 days is 0.21 ± 0.06—same as the normal frequency of such binaries among solar-type stars, 0.18. This indicates that wide binaries are unlikely to be produced by dynamical evolution of N-body systems, but are rather formed by fragmentation.

    Multiple stellar populations are a widespread phenomenon among Galactic globular clusters. Even though the origin of the enriched material from which new generations of stars are produced remains unclear, it is likely that self-enrichment will be feasible only in clusters massive enough to retain this enriched material. We searched for multiple populations in the low mass (M˜ 1.4× {10}4 {M}⊙ ) globular cluster E3, analyzing SOAR/Goodman multi-object spectroscopy centered on the blue cyanogen (CN) absorption features of 23 red giant branch stars. We find that the CN abundance does not present the typical bimodal behavior seen in clusters hosting multistellar populations, but rather a unimodal distribution that indicates the presence of a genuine single stellar population, or a level of enrichment much lower than in clusters that show evidence for two populations from high-resolution spectroscopy. E3 would be the first bona fide Galactic old globular cluster where no sign of self-enrichment is found.

    The results of speckle interferometric observations at the Southern Astrophysical Research Telescope (SOAR) telescope in 2014 are given. A total of 1641 observations were taken, yielding 1636 measurements of 1218 resolved binary and multiple stars and 577 non-resolutions of 441 targets. We resolved for the first time 56 pairs, including some nearby astrometric or spectroscopic binaries and ten new subsystems in previously known visual binaries. The calibration of the data is checked by linear fits to the positions of 41 wide binaries observed at SOAR over several seasons. The typical calibration accuracy is 0.°1 in angle and 0.3% in pixel scale, while the measurement errors are on the order of 3 mas. The new data are used here to compute 194 binary star orbits, 148 of which are improvements on previous orbital solutions and 46 are first-time orbits.

    The study of selected mafic intrusions from cratonic areas of the South American Platform shows considerable differences among their mantle sources and geodynamic features, particularly regarding the dikes from the SW Amazonian and São Francisco Cratons. The tholeiites from the SW Amazonian Craton, which belong to the Serra da Providência Intrusive Suite (1.55 Ga), the Nova Lacerda swarm (1.44 Ga), the Colorado Complex (1.35 Ga), and the Nova Brasilândia Group (1.10 Ga), originated from a mantle source composed mainly of a N-MORB end-member, with a variable addition of slab fluids (up to 30%, according to the adopted model) from oceanic lithosphere due to episodic subductions during the Mesoproterozoic. Mafic intrusions from Nova Lacerda swarm and Colorado Complex are related to arc settings formed during the 1.47-1.35 Ga closure of the oceanic domain separating the Amazonian Craton and the Paraguá Terrane, whereas the tholeiites from the Serra da Providência Intrusive Suite and the Nova Brasilândia Group are considered intracratonic. The dike swarms of the São Francisco Craton are associated with intra-plate events. The inferred composition of the mantle source of the Lavras swarm (1.9 Ga) has a predominant E-MORB signature, and a modest contribution of up to 10% of an OIB component. The mantle composition underwent considerable changes during the Proterozoic, as indicated by the sources of the younger dikes, represented by the Diamantina (0.93 Ga) and the Salvador-Olivença swarms (0.92 Ga), to which considerable amount of slab derived fluids, probably from recycled crustal material, and OIB component were added. Changes in mantle composition and dikes intrusions could be related to the initial disruption of the Rodinia Supercontinent. The Florida (1.79 Ga) and Tandil (2.0 Ga) dikes are associated with extensional events of the Rio de La Plata Craton. In spite of the similarities between the tectonic framework of these swarms and that of Lavras (1.9 Ga

    Abstract Background At least 511 species of birds occur in the semiarid region of northeastern Brazil and many of them interact with human populations in a number of different ways, including their use in zootherapeutics and their links with local beliefs. Objective The present work examined these types of birds/human interactions (use in zootherapeutics and their links with local beliefs) in the semiarid region of Rio Grande do Norte State in northeastern Brazil. Methods Information was obtained through semi-structured interviews with 120 local residents. Results A total of 16 wild bird species distributed among 11 families were found to interact directly with humans, with Columbidae being the best represented family. Seven species were identified in the medicinal category, five were related to symbolic aspects, while four species were identified as being related to both categories (medicinal and symbolic). Conclusion The accumulated folk knowledge, beliefs, and practices involving the avifauna in the semiarid region of Brazil, whether symbolic or medicinal, demonstrated the cultural importance of this vertebrate group to local human populations and revealed a belief system intrinsically related to cynegetic practices in the region.

    As part of the commemorations of the International Year of the Physics and having as its main objective to introduce students to the scientific method, the Rio de Janeiro Planetarium Foundation, in partnership with many institutions of Brazil and Europe, coordinated the activity "Reviving Eratosthenes" whose objective was the determination of the Earth's circumference. We used the famous procedure adopted by Eratosthenes more than 2000 years ago, with some adaptations. This work considers and analyzes the method used by us, aiming the application in schools. The use of places in different meridians allows a better understanding of the abstract concepts such as geographic coordinate and time zones. We obtained reasonably precise results, which improve for pairs of distant cities. Finally, one of the most important conclusions achieved by the students involved is the importance of the cooperation (international in this case) to solve problems. Fazendo parte das comemorações do Ano Internacional da Física e tendo como principal objetivo introduzir estudantes do ensino médio ao método científico, a Fundação Planetário da Cidade do Rio de Janeiro, em parceria com diversas instituições do Brasil e da Europa, coordenou a atividade "Revivendo Eratóstenes" cujo objetivo foi a determinação da circunferência da Terra. Para isso, utilizou-se um procedimento semelhante ao empregado pelo sábio Eratóstenes há mais de 2.000 anos, com algumas adaptações. Este trabalho propõe e analisa o método que empregamos, visando a aplicação em escolas. A possibilidade de se trabalhar com locais em diferentes meridianos permite uma melhor compreensão dos conceitos mas abstratos, como coordenadas e fusos horários. A precisão dos resultados é bastante razoável, melhorando para cidades bem afastadas. Finalmente, uma das conclusões mais importantes é a percepção, por parte dos estudantes, da importância da colaboração (neste caso, internacional) para resolver

    In the 30 years of the AIDS pandemic in Brazil, it is recognized the HIV virus internalization of the phenomenon as a challenge to care and current health policies. In this sense, it aimed to verify sex practices and social representations that rural towns residents have about the disease. Attended by 789 people, men and women, between 18 and 90 years old, residents in 41 towns with fewer than 11,000 inhabitants in the state of Paraiba / Brazil. Data were collected by a questionnaire and the free association of words test. The results showed low concern about disease, perception of invulnerability to HIV infection and not using condoms during sexual intercourse, and confidence in the major reason related partner. Also showed endure derogatory and stereotypical representations, revealing that still persist in rural areas, beliefs and representations concerning the beginning of the epidemic. From these findings, it is possible to point out deficiencies in the care provided by the health services in these localities, which may result in increased vulnerability of this population to diseases, so there is the need to intensify information campaigns and intervention. The results reveal the existence of three different types of modes of learning health literacy skills in informal context: : i) learning that takes place in action, in achieving daily tasks; ii) learning processes that result from problem solving; iii) learning that occurs in an unplanned manner, resulting from accidental circumstances and, in some cases, devoid of intentionality. Nos 30 anos da pandemia da Aids no Brasil, reconhece-se o fenômeno da interiorização do vírus HIV como um desafio ao cuidado e às politicas de saúde atuais.

Using Paulo Freire's contextualization and dialogicity ideas as a theoretical framework guided by these lessons, it was proposed to the students the assembly and application of that resource in a planetarium session. During the project, some subjects such as the apparent trajectory of stars through Brasilia's sky, the location of the cardinal points beginning from the Southern Cross constellation, the color of stars and the stars being seen from a particular place were emphasized. It was found that the students showed an improvement of their understanding about these subjects, as well as a significant excitement with the developed methodology.

The tools and services provided by Unidata are available to the research and education community free-of-charge. Data sharing capabilities are being provided by Unidata's Internet Data Distribution (IDD) system, a community-based effort that has been the primary source of real-time meteorological data in the US university community for over a decade. A collaboration among Unidata, Brazil's Centro de Previso de Tempo e Estudos Climaticos (CPTEC), the Universidad Federal do Rio de Janeiro (UFRJ), and the Universidade de Sao Paulo (USP) has resulted in the creation of a Brazilian peer of the North American IDD, the IDD-Brasil. Collaboration between Unidata and the Universidad de Costa Rica (UCR) seeks to extend IDD data sharing throughout Central America and the Caribbean in an IDD-Caribe. Efforts aimed at creating a data sharing network for researchers on the Antarctic continent have resulted in the establishment of the Antarctic-IDD.

    Risk assessment can provide a comprehensive estimate of potential effects of contaminants under specific, well-defined, and well-described circumstances, providing quantitative relationships between exposure and effects to identify and to define areas of concern. We investigated the mutagenic activity of particulate matter in air samples collected from three sites in Rio de Janeiro city. Samples were collected using a high-volume sampler at Avenida Brasil, at Campus of Universidade do Estado do Rio de Janeiro, and at Rebouças Tunnel. Six polycyclic aromatic hydrocarbons were quantified by gas chromatography/mass spectrometry. Salmonella typhimurium TA98 and the derivative strains TA98/1.8-DNP(6), YG1021, and YG1024, commonly used in mutagenicity assays, were treated (10-50 µg/plate), with and without exogenous metabolization. The highest values for the polycyclic aromatic hydrocarbons were detected at Rebouças Tunnel. For chrysene, as an example, the concentration was nearly 200 times higher than that established by the US Environmental Protection Agency. Frequent traffic jams can place bus drivers who go through the Rebouças Tunnel at risk of exposure to up to 0.69 ng/m(3) benzo(a) pyrene. Independent of exogenous metabolization, mutagenicity was detected in strains YG1021 and YG1024 at all the sites, suggesting nitro and amino derivatives of polycyclic aromatic hydrocarbons. Rebouças Tunnel air samples gave the highest values for rev/µg and rev/m(3). This could be due to the fact that the long, enclosed passageway through a mountain restricts ventilation. The cancer risk estimate in this study was 10(-3) for the benzo(a)pyrene, at the two sites, indicating a high risk.

    The present study was developed to respond to the need for an increase in crop yield in the mountain region of Caparaó (southern Espírito Santo State, Brazil), an area of traditional coffee production. This study aimed to analyze the diversity and characterize the crop yield of genotypes of Coffea arabica L. with potential for cultivation in high plant density systems. In addition, it also aimed to quantify the expression of agronomic traits in this cultivation system and provide information on the genotypes with the highest cultivation potential in the studied region. The experiment followed a randomized block design with 16 genotypes, four repetitions, and six plants per experimental plot. Plant spacing was 2.00 x 0.60 m, with a total of 8333 plants per hectare, representing a high-density cultivation system. Coffee plants were cultivated until the start of their reproductive phenological cycles and were evaluated along four complete reproductive cycles. Genotypes with high crop yield and beverage quality, short canopy, and rust resistance were selected. C. arabica genotypes showed variability in almost all characteristics. It was possible to identify different responses among genotypes grown in a high plant density cultivation system. Although the chlorophyll a content was similar among genotypes, the genotypes Acauã, Araponga MG1, Sacramento MG1, Tupi, and Catuaí IAC 44 showed a higher chlorophyll b content than the other genotypes. Among these, Sacramento MG1 also showed high leafiness and growth of vegetative structures, whereas Araponga MG1, Pau-Brasil MG1, and Tupi showed high fruit production. In addition, Araponga MG1 had also a higher and more stable crop yield over the years.

    At the outlet of mountain ranges, rivers flow onto flatter lowlands. The associated change of slope causes sediment deposition. As the river is free to move laterally, it builds conical sedimentary structures called alluvial fans. Their location at the interface between erosional and depositional areas makes them valuable sedimentary archives. To decipher these sedimentary records, we need to understand the dynamics of their growth. Most natural fans are built by braided streams. However, to avoid the complexity of braided rivers, we develop a small-scale experiment in which an alluvial fan is formed by a single channel. We use a mixture of water and glycerol to produce a laminar river. The fluid is mixed with corindon sand (~ 300 μm) in a tilted channel and left free to form a fan around its outlet. The sediment and water discharges are constant during an experimental run. We record the fan progradation and the channel morphology with top-view pictures. We also generate an elevation map with an optical method based on the deformation of a moiré pattern. We observe that, to leading order, the fan remains self-affine as it grows, with a constant slope. We compare two recent studies about the formation of one-dimensionnal fan [Guerit et al. 2014] and threshold rivers [Seizilles et al. 2013] to our experimental findings. In particular, we propose a theory witch relates the fan morphology to the control parameters ( fluid and sediment discharges, grain size). Our observation accord with the predictions, suggesting that the fan is built near the threshold of sediment motion. Finally, we intend to expand our interpretation to alluvial fans build by single-thread channels ( Okavango, Bostwana; Taquari and Paraguay, Brasil; Pastaza, Peru).

    The image-subtraction technique applied to study variable stars in globular clusters represented a leap in the number of new detections, with the drawback that many of these new light curves could not be transformed to magnitudes due to severe crowding. In this paper, we present observations of four Galactic globular clusters, M 2 (NGC 7089), M 10 (NGC 6254), M 80 (NGC 6093), and NGC 1261, taken with the ground-layer adaptive optics module at the SOAR Telescope, SAM. We show that the higher image quality provided by SAM allows for the calibration of the light curves of the great majority of the variables near the cores of these clusters as well as the detection of new variables, even in clusters where image-subtraction searches were already conducted. We report the discovery of 15 new variables in M 2 (12 RR Lyrae stars and 3 SX Phe stars), 12 new variables in M 10 (11 SX Phe and 1 long-period variable), and 1 new W UMa-type variable in NGC 1261. No new detections are found in M 80, but previous uncertain detections are confirmed and the corresponding light curves are calibrated into magnitudes. Additionally, based on the number of detected variables and new Hubble Space Telescope/UVIS photometry, we revisit a previous suggestion that M 80 may be the globular cluster with the richest population of blue stragglers in our Galaxy.

    This study investigated for the first time the reproductive biology of Prochilodus lineatus in a system of rivers in southeastern Brasil, relating it to the role of tributary rivers in the reproductive success of this important commercial fish in the Upper Paraná River basin, where a cascade of hydroelectric dams were deployed. Specimens were caught bimonthly in three river sites: (S1) Grande River, downstream from the Porto Colômbia dam; (S2) Pardo River; and (S3) Mogi Guaçu River. Sex steroid plasma levels, fecundity, follicular atresia, oocyte diameter and gonadosomatic index (GSI) were compared among sites. In S1, fish exhibited changes in the reproductive parameters: lower GSI, oocyte diameter and fecundity and higher follicular atresia index, when compared to S2 and S3. Frequency of maturing fish was higher in S3 and spawning was only registered in S3. In sites S2 and S3, plasma concentrations of testosterone and 17β-estradiol in females and testosterone in males showed wide variations following gonadal maturation. Fish from S1 showed few significant variations in sex steroid concentrations throughout the gonadal cycle. These results indicate that P. lineatus does not reproduce in Grande River (S1), but probably uses the Pardo River (S2) as a migratory route towards the Mogi Guaçu River (S3) where they complete gonadal maturation and spawning. Our findings contribute for understanding the reproductive biology of P. lineatus and to highlight the importance of tributaries in impounded rivers as a favourable environment for migration and spawning of fish.

    Background The Arc of Fire across southern Amazonia seasonally attracts worldwide attention as forests are cut and burned for agricultural expansion. These forests contain numerous wild relatives of native South American crops, such as peach palm. Methodology/Principal Findings Our prospecting expeditions examined critical areas for wild peach palm in the Arc of Fire in Mato Grosso, Pará, Maranhão and Tocantins, as well as areas not previously examined in Amazonas and Amapá states. Recent digitization of the RADAM Brasil project permitted comparison among RADAM's parataxonomists' observations, previous botanical collections and our prospecting. Mapping on soils and vegetation types enabled us to hypothesize a set of ecological preferences. Wild peach palm is best adapted to Ultisols (Acrisols) in open forests across the Arc of Fire and westward into the more humid western Amazonia. Populations are generally small (fewer than 10 plants) on slopes above watercourses. In northern Mato Grosso and southern Pará soybean fields and pastures now occupy numerous areas where RADAM identified wild peach palm. The controversial BR-163 Highway is already eroding wild peach palm as deforestation expands. Conclusions/Significance Many of these populations are now isolated by increasing forest fragmentation, which will lead to decreased reproduction via inbreeding depression and eventual extinction even without complete deforestation. Federal conservation areas are less numerous in the Arc of Fire than in other parts of Brazilian Amazonia, although there are indigenous lands; these conservation areas contain viable populations of wild peach palm and require better protection than they are currently receiving. Ex situ conservation of these populations is not viable given the relative lack of importance of domesticated peach palm and the difficulty of maintaining even economically interesting genetic resources.

    The present study aimed to evaluate ivermectin and abamectin, both administered orally in naturally infected domestic swine, as well as analysing if the EPG (eggs per gram of faeces) values were equivalent with the ivermectin and abamectin efficacy obtained by parasitological necropsies. The animals were randomly selected based on the average of three consecutive EPG counts of Strongylida, Ascaris suum and Trichuris for experiment I, and of Strongylida and Trichuris for experiment II. After the random draw, eight animals were treated, orally, during seven consecutive days with 100 µg/kg/day ivermectin (Ivermectina® premix, Ouro Fino Agronegócios), eight other animals were treated, orally, during seven consecutive days with 100 µg/kg/day abamectin (Virbamax® premix - Virbac do Brasil Indústria e Comércio Ltda.), and eight pigs were kept as controls. EPG counts were performed for each individual animal at 14th day post-treatment (DPT). All animals (control and treatment) were necropsied at the 14th DPT. The results from both experiments demonstrate that both ivermectin and abamectin, administered orally for a continuous period of seven days, at a daily dosage of 100 µg/kg, were highly effective (>95%) against Hyostrongylus rubidus, Strongyloides ransomi, Ascaris suum and Metastrongylus salmi. Against Oesophagostomum dentatum, abamectin presented over 95% efficacy against both evaluated strains, while ivermectin reached other strain as resistant. Regarding T. suis, both ivermectin and abamectin were effective (efficacies >90%) against one of the tested strains, while the other one was classified as resistant. Furthermore, the EPG values were equivalent with the ivermectin and abamectin efficacy obtained by parasitological necropsies.

    The present study was developed to respond to the need for an increase in crop yield in the mountain region of Caparaó (southern Espírito Santo State, Brazil), an area of traditional coffee production. This study aimed to analyze the diversity and characterize the crop yield of genotypes of Coffea arabica L. with potential for cultivation in high plant density systems. In addition, it also aimed to quantify the expression of agronomic traits in this cultivation system and provide information on the genotypes with the highest cultivation potential in the studied region. The experiment followed a randomized block design with 16 genotypes, four repetitions, and six plants per experimental plot. Plant spacing was 2.00 x 0.60 m, with a total of 8333 plants per hectare, representing a high-density cultivation system. Coffee plants were cultivated until the start of their reproductive phenological cycles and were evaluated along four complete reproductive cycles. Genotypes with high crop yield and beverage quality, short canopy, and rust resistance were selected. C. arabica genotypes showed variability in almost all characteristics. It was possible to identify different responses among genotypes grown in a high plant density cultivation system. Although the chlorophyll a content was similar among genotypes, the genotypes Acauã, Araponga MG1, Sacramento MG1, Tupi, and Catuaí IAC 44 showed a higher chlorophyll b content than the other genotypes. Among these, Sacramento MG1 also showed high leafiness and growth of vegetative structures, whereas Araponga MG1, Pau-Brasil MG1, and Tupi showed high fruit production. In addition, Araponga MG1 had also a higher and more stable crop yield over the years. PMID:26909972

  6. South Atlantic sag basins: new petroleum system components

    Newly discovered pre-salt source rocks, reservoirs and seals need to be included as components to the petroleum systems of both sides of the South Atlantic. These new components lie between the pre-salt rift strata and the Aptian salt layers, forming large, post-rift, thermal subsidence sag basins. These are differentiated from the older rift basins by the lack of syn-rift faulting and a reflector geometry that is parallel to the base salt regional unconformity rather than to the Precambrian basement. These basins are observed in deep water regions overlying areas where both the mantle and the crust have been involved in the extension. This mantle involvement creates post-rift subsiding depocenters in which deposition is continuous while proximal rift-phase troughs with little or no mantle involvement are bypassed and failed to accumulate potential source rocks during anoxic times. These features have been recognized in both West African Kwanza Basin and in the East Brasil Rift systems. The pre-salt source rocks that are in the West African sag basins were deposited in lacustrine brackish to saline water environment and are geochemically distinct from the older, syn-rift fresh to brackish water lakes, as well as from younger, post-salt marine anoxic environments of the drift phase. Geochemical analyses of the source rocks and their oils have shown a developing source rock system evolving from isolated deep rift lakes to shallow saline lakes, and culminating with the infill of the sag basin by large saline lakes to a marginally marine restricted gulf. Sag basin source rocks may be important in the South Atlantic petroleum system by charging deep-water prospects where syn-rift source rocks are overmature and the post-salt sequences are immature.

    This work presents a method for the evaluation of location accuracy of all Lightning Location System (LLS) in operation in southeastern Brazil, using natural cloud-to-ground (CG) lightning flashes. This can be done through a multiple high-speed cameras network (RAMMER network) installed in the Paraiba Valley region - SP - Brazil. The RAMMER network (Automated Multi-camera Network for Monitoring and Study of Lightning) is composed by four high-speed cameras operating at 2,500 frames per second. Three stationary black-and-white (B&W) cameras were situated in the cities of São José dos Campos and Caçapava. A fourth color camera was mobile (installed in a car), but operated in a fixed location during the observation period, within the city of São José dos Campos. The average distance among cameras was 13 kilometers. Each RAMMER sensor position was determined so that the network can observe the same lightning flash from different angles and all recorded videos were GPS (Global Position System) time stamped, allowing comparisons of events between cameras and the LLS. The RAMMER sensor is basically composed by a computer, a Phantom high-speed camera version 9.1 and a GPS unit. The lightning cases analyzed in the present work were observed by at least two cameras, their position was visually triangulated and the results compared with BrasilDAT network, during the summer seasons of 2011/2012 and 2012/2013. The visual triangulation method is presented in details. The calibration procedure showed an accuracy of 9 meters between the accurate GPS position of the object triangulated and the result from the visual triangulation method. Lightning return stroke positions, estimated with the visual triangulation method, were compared with LLS locations. Differences between solutions were not greater than 1.8 km.

    Objetivo: Caracterizar los hábitos alimenticios, el estado nutricional y la calidad de vida de pacientes en el periodo posoperatorio de la cirugía bariátrica de Fobi-Capella. Métodos: Se realizó un estudio analítico transversal en 66 pacientes sometidos a cirugía bariátrica y monitorizados por el personal del Hospital Universitario Oswaldo Cruz (HUOC), en el noreste de Brasil. Se aplicó un cuestionario que contemplaba características sociodemográficas e información demográfica relativa a los hábitos alimenticios, y también se evaluaba la calidad de vida por el método BAROS. Resultados: En la tolerancia a los alimentos, en la categoría de «difícil de comer» se notificaron alimentos tales como carne, pollo, arroz, ensalada cruda y maíz y en la «no ingeridos» estaban maíz, seguido de caramelos, carne y pollo. Hubo una reducción del peso corporal total y del IMC y, en consecuencia, un aumento del PEP% con el tiempo. Con respecto a la calidad de vida, se pudo observar que la mayor parte de los pacientes la clasificaron como «buena» en ambos grupos de 6-18 meses y de > 18 meses. Conclusiones: Nuestro resultados demuestran que la cirugía bariátrica produjo unos efectos satisfactorios en esta población; sin embargo, existe la necesidad de una educación nutricional continuada, especialmente en el grupo de más de 18 meses tras la cirugía.

    The asteroid 221 Eos (K class), has been traditionally associated to CO/CV meteorites (Bell 1988). This association is based solely on spectral similarities with meteorites, and previously the best spectral analog to Eos was found to be the CO3 Warrenton (Burbine et al. 2001). The 52-color spectrum (http://pdssbn.astro.umd.edu/) and the SMASSIR spectrum (Burbine and Binzel 2001) of 221 Eos in the NIR region, combined with the SMASSII spectrum (Bus and Binzel 2001) in the visible, has now been compared to the whole RELAB meteorites database (http://www.planetary.brown.edu/relab/rel_pub/) updated on July 31, 2003. This comparison revealed a better spectral analog to Eos: the anomalous stone Divnoe, a primitive achondrite meteorite. Problems and implications of such match for the composition of Eos and its dynamical family will be discussed. This work has been supported by the Conselho Nacional de Desenvolvimento Científico e Tecnológico - CNPq/Brasil. References: Bell, J.F. 1988.

  10. Estructuras circumnucleares en la galaxia Seyfert interactuante NGC 1241

    Díaz, R. J.; Carranza, G.; Dottori, H.

    We have studied the rotation curve and morphology of the central 10 kiloparsecs (~40'') of NGC 1241 obtaining 50 radial velocity measurements in three different position angles. These observations indicate a large velocity gradient of 70 km/sec/('') in the central 5''. The fitting of different density distribution laws to the derived rotation curve indicates a mass of ~ 9 E9 Msolar in the inner kpc. HST-NICMOS images show the presence of a circumnuclear star formation ring at radius ~ 2.8'' (720 pc). This ring is more defined than most of the known cases and harbours a mini-bar and nuclear spiral arms with a sense of rotation opposite than the main spiral arms. This morphological evidence suggest the presence of a dynamically decoupled system inside the circumnuclear ring. As in other cases studied by us, the ring seems to be inside an Inner Lindblad Resonance and the Lindblad curve ω-κ/2 for this object begins to drop for Rmax = 400 pc (~1.5''), but the limited spatial resolution does not allow us to find out a definitive evidence for the existence of a second ILR inside at inner radii. Up to date there is no published morphological or kinematical evidence for the presence of a second ILR at such small radii, a necessary ingredient for the presence of circumnuclear ring of star formation, considering the results of recent hydrodynamic simulations. We have proposed the observation of NGC 1241 with better instruments in order to extend the rotation curve to the central 2'', unveil the presence of a second inner resonance, study in detail the structural properties of the nuclear counterrotating arms and establish accurate models of mass distribution in galaxies with circumnuclear rings.

    Planctomyces brasiliensis Schlesner 1990 belongs to the order Planctomycetales, which differs from other bacterial taxa by several distinctive features such as internal cell compartmentalization, multiplication by forming buds directly from the spherical, ovoid or pear-shaped mother cell and a cell wall consisting of a proteinaceous layer rather than a peptidoglycan layer. The first strains of P. brasiliensis, including the type strain IFAM 1448 T, were isolated from a water sample of Lagoa Vermelha, a salt pit near Rio de Janeiro, Brasil. This is the second completed genome sequence of a type strain of the genus Planctomyces to be published andmore » the sixth type strain genome sequence from the family Planctomycetaceae. The 6,006,602 bp long genome with its 4,811 protein-coding and 54 RNA genes is a part of the Genomic Encyclopedia of Bacteria and Archaea project. We study phylogenomic analyses that indicate that the classification within the Planctomycetaceae is partially in conflict with its evolutionary history, as the positioning of Schlesneria renders the genus Planctomyces paraphyletic. A re-analysis of published fatty-acid measurements also does not support the current arrangement of the two genera. A quantitative comparison of phylogenetic and phenotypic aspects indicates that the three Planctomyces species with type strains available in public culture collections should be placed in separate genera. Thus the genera Gimesia, Planctopirus and Rubinisphaera are proposed to accommodate P. maris, P. limnophilus and P. brasiliensis, respectively. Pronounced differences between the reported G + C content of Gemmata obscuriglobus, Singulisphaera acidiphila and Zavarzinella formosa and G + C content calculated from their genome sequences call for emendation of their species descriptions. Lastly, in addition to other features, the range of G + C values reported for the genera within the Planctomycetaceae indicates that the descriptions of the family and the

    The first systematic asronomical observations in the southern hemisphere were in Pernambuco, northeastern Brazil, in the short period of Dutch rule in the region (1637-1644). Later, in the late nineteenth and early twentieth centuries, there were three observatories on Brazilian soil: Imperial Observatório do Rio de Janeiro, Observatório da Escola Politecnica, both in Rio de Janeiro and Observatório Central, in the southern city of Porto Alegre. The first was created by Imperial decree by D. Pedro I, on 15 October 1827, while the second, linked to Universidade do Brasil, was established on 5 July 1881. The third was planned in 1889, but only inaugurated on 24 January 1908 as part of the Escola de Engenharia. All three institutions exist to this day, and their scientific instruments of historical value are included in cultural heritage preservation projects. The largest collection of this kind of objects is at Museu de Astronomia e Ciéncias Afins (MAST), most of whose 2000 artefacts come from the Imperial Observatory (today the National Observatory). Many of them were produced in Germany by manufacturers such as Gustav Heyde, Carl Zeiss, Askania-Werke, Carl Bamberg and Max Kohl. The buildings of the Observatório Central (1921) and Observatório Nacional (1921) are listed by federal and state heritage protection agencies, particularly because they were purpose built for astronomical research and have architectural features typical of the late nineteenth and early twentieth centuries that have not been altered over the years.

    The objective of Brazilian Eratosthenes Project is the development and application of teaching training actions according the ``docent autonomy" concept to basic Astronomy Education. Argentina coordinates the project in South America, but Brazil works in this project since 2010 with the theme ``Projeto Eratóstenes Brasil" in the homepage: http://sites.google.com/site/projetoerato. Two schools measure a sticks shadow and communicate their results. After, they calculate an average radius of Earth. The stick (gnomon) should stay in vertical position in the leveled ground. Since 2010, the project received hundreds of Brazilian schools with different experiments that were constructed with autonomy, because our site doesn't show some itinerary pre-ready to elaborate the experiments. To collect data for our research, we will use interviews via Skype with the teachers. These data are useful to researches about Science Education area and the Teaching Formation. Teaching professional practice could change and we see modifications in the teachers work, what depends of their realities and context. This project intents to respect the docent autonomy. This autonomy to responsible modifications during continued formation is called ``activist formative model" according Langhi & Nardi (Educação em Astronomia: repensando a formação de professores. São Paulo: Escrituras Editora, 2012). This project discusses about researches in Astronomy Education - still extreme rare in Brazil, when we compare with other areas in Science Education. We believe that actions like this could motivate the students to learn more Astronomy. Furthermore, this national action can be a rich source of data to investigations about teaching formation and scientific divulgation.

    The present study aimed to evaluate ivermectin and abamectin, both administered orally in naturally infected domestic swine, as well as analysing if the EPG (eggs per gram of faeces) values were equivalent with the ivermectin and abamectin efficacy obtained by parasitological necropsies. The animals were randomly selected based on the average of three consecutive EPG counts of Strongylida, Ascaris suum and Trichuris for experiment I, and of Strongylida and Trichuris for experiment II. After the random draw, eight animals were treated, orally, during seven consecutive days with 100 µg/kg/day ivermectin (Ivermectina® premix, Ouro Fino Agronegócios), eight other animals were treated, orally, during seven consecutive days with 100 µg/kg/day abamectin (Virbamax® premix - Virbac do Brasil Indústria e Comércio Ltda.), and eight pigs were kept as controls.

    This study investigated for the first time the reproductive biology of Prochilodus lineatus in a system of rivers in southeastern Brasil, relating it to the role of tributary rivers in the reproductive success of this important commercial fish in the Upper Paraná River basin, where a cascade of hydroelectric dams were deployed. Specimens were caught bimonthly in three river sites: (S1) Grande River, downstream from the Porto Colômbia dam; (S2) Pardo River; and (S3) Mogi Guaçu River. Sex steroid plasma levels, fecundity, follicular atresia, oocyte diameter and gonadosomatic index (GSI) were compared among sites. In S1, fish exhibited changes in the reproductive parameters: lower GSI, oocyte diameter and fecundity and higher follicular atresia index, when compared to S2 and S3. Frequency of maturing fish was higher in S3 and spawning was only registered in S3. In sites S2 and S3, plasma concentrations of testosterone and 17β-estradiol in females and testosterone in males showed wide variations following gonadal maturation. Fish from S1 showed few significant variations in sex steroid concentrations throughout the gonadal cycle. These results indicate that P. lineatus does not reproduce in Grande River (S1), but probably uses the Pardo River (S2) as a migratory route towards the Mogi Guaçu River (S3) where they complete gonadal maturation and spawning. Our findings contribute for understanding the reproductive biology of P. lineatus and to highlight the importance of tributaries in impounded rivers as a favourable environment for migration and spawning of fish.

    Background and Objective: Human visceral leishmaniasis is endemic in Natal, northeast of Brazil, where the domestic dog is an important parasite reservoir in the infectious cycle of Leishmania spp. In this study, was evaluated the antileishmanial IgG antibody and epidemiological factors related to canine visceral leishmaniasis (CVL). Methods: Sera samples obtained by venipuncture of 1,426 dogs living in areas of human visceral leishmaniasis occurrence were tested for detection of IgG anti-leishmania antibodies with Immunofluorescence Antibody Assay (IFA) and Enzyme Linked Immunosorbent Assay (ELISA). Chi-square (x2) and Odds Ratio (OR) were calculated. Differences were considered statistically significant at p≤0.05. RESULTS: The overall seroprevalence was 10.30% (147/1,426); prevalence increased when the samples were found to be positive at least for one technique ([417/1,426] 29.3%). The high percentage of seroprevalence was observed in Nova República (15.35%), Nova Natal I (12.7%) and Lagoa Azul (11.4%) neighborhoods. In the Planalto, Soledade and Brasil Novo, the infection rates ranged from 7.5 at 8.06%. (p=0.00051). There was neither statistically significant difference between leishmanial infection nor clinical signs of disease (p=0.84; OR=1.0 [0.41; 2.3]), sex (p=0.78, OR=0.94 [0.66; 1.28]); and breed (p=0.92; OR=1.0 [0.65; 1.54]) were observed. Conclusion: The RESULTS suggest that CVL is widely distributed in Natal, may be increasingly urbanizing and will spread through neighborhoods but not endemic, resulting in a serious public health problem, emphasizing the need for epidemiological studies to a greater understanding of the distribution of canine leishmaniasis in these specific areas and contribute proactively to the public health policies.

    Nickel mining of ultramafic laterites generates different types of wastes, topsoils and ores that are too poor in Ni to be currently processed. These are mixed and stored on heaps which could be a potential source of Ni and Cr pollution. Chemical reactivity of the main metal bearing phases present in the mining spoils of Goiás (Brasil) was investigated. Principally a silicated 'saprolite' material and a Fe-oxide rich limonitic material were isolated from the wastes. Their total Ni and Cr content are high, respectively for Ni and Cr : 7,170 and 54,970 mg kg-1 in limonite and 12,200 and 12,650 mg kg-1 in saprolite. The main metal-bearing minerals, identified and localized using XRD, TEM-EDX, Raman spectroscopy and Mossbaüer spectrometry are well-crystallized minerals: goethite (75%), hematite (13%) and chromite in limonite and ferruginous smectite, talc and chromite in saprolite. Single and sequential extractions showed that the amounts of 1M KCl exchangeable Ni and Cr reached respectively 7.1% and 0.03% of total contents in saprolite. Moreover, Cr(VI) extraction by KH2PO4 showed that more than 2% (980 mg kg-1) of total Cr was under this labile toxic form in limonite. This study allowed us to determine the main reactions controlling the Ni and Cr mobility in the spoils i.e. Ni2+ cationic exchange in saprolitic spoil and CrO32- surface complexation in limonitic spoil. This study allowed us to demonstrate the need of chemical rehabilitation of mining wastes in order to avoid the dispersion of the high contents of Ni and Cr available. It constitutes the system definition needed to predict the Cr and Ni mobility in ultramafic mining spoils.

    The life of the Vienna-born writer Stefan Zweig, whose centenary will be on November 28th, 1981, is portrayed in the light of some external data. His works - mainly novellas - in which the theme of suicide plays a central role, are briefly presented, and his preference for describing psychological borderline and extreme states is stressed. One of his first poems and his last one - more than forty years lie between them - are discussed with reference to his depression and suicidal tendencies. Zweig, who at least since the First World war had been periodically suffering from depressions, was looked after and in a sense also treated by his first wife Friderike von Winternitz, until he had to leave his home in Salzburg in 1935. In 1939, he divorced from his wife and married his sickly secretary, Lotte Altmann, who suffered from asthma and depression. After prolonged stays in England, North and South America he settled in Petropolis near Rio de Janeiro in Brasil, where he spent the last months of his life. Zweig was the second son of a dominating, self-willed mother and a dignified, almost "motherly" father. He felt his childhood to have been constricted and hemmed in. His narcissism, which has played an essential role in relation to his suicide, has its roots in his childhood. Direct as well as indirect hints at suicide were not lacking during the last two years of Zweig's life, which were increasingly filled with depression and anxiety. The preface to his autobiography "The World of Yesterday" may be interpreted as an indirect announcement of suicide. On February 22nd, 1942, Zweig committed suicide together with his second wife in Petropolis.

    To produce a new daily record of gross carbon emissions from biomass burning events and post-burning decomposition fluxes in the states of the Brazilian Legal Amazon (Instituto Brasileiro de Geografia e Estatistica (IBGE), 1991. Anuario Estatistico do Brasil, Vol. 51. Rio de Janeiro, Brazil pp. 1-1024). We have used vegetation greenness estimates from satellite images as inputs to a terrestrial ecosystem production model. This carbon allocation model generates new estimates of regional aboveground vegetation biomass at 8-km resolution. The modeled biomass product is then combined for the first time with fire pixel counts from the advanced very high-resolution radiometer (AVHRR) to overlay regional burning activities in the Amazon. Results from our analysis indicate that carbon emission estimates from annual region-wide sources of deforestation and biomass burning in the early 1990s are apparently three to five times higher than reported in previous studies for the Brazilian Legal Amazon (Houghton et al., 2000. Nature 403, 301-304; Fearnside, 1997. Climatic Change 35, 321-360), i.e., studies which implied that the Legal Amazon region tends toward a net-zero annual source of terrestrial carbon. In contrast, our analysis implies that the total source fluxes over the entire Legal Amazon region range from 0.2 to 1.2 Pg C yr -1, depending strongly on annual rainfall patterns. The reasons for our higher burning emission estimates are (1) use of combustion fractions typically measured during Amazon forest burning events for computing carbon losses, (2) more detailed geographic distribution of vegetation biomass and daily fire activity for the region, and (3) inclusion of fire effects in extensive areas of the Legal Amazon covered by open woodland, secondary forests, savanna, and pasture vegetation. The total area of rainforest estimated annually to be deforested did not differ substantially among the previous analyses cited and our own.

    Objetivo: Realizar una revisión sistemática de los estudios transversales sobre la prevalencia de actividad física insuficiente (IPA) sobre la de base a un punto de corte definido por la OMS (< 60 min/d de actividad física moderada y vigorosa). Métodos: La búsqueda se llevó a cabo utilizando bases de datos en línea (BioMed Central, CINAHL, EMBASE, ERIC, PsycInfo, Medline PubMed, SCOPUS, SPORTDiscus), e incluyó artículos publicados desde el inicio de las bases de datos hasta 18 de febrero de 2012, así como las referencias citadas por los artículos recuperados y la información proporcionada por los autores. Sólo artículos originales que evaluaban el nivel de actividad física mediante cuestionarios fueron considerados. Resultados: De los 2.384 artículos recuperados inicialmente, quince estudios cumplieron los criterios de inclusión, de los cuales siete fueron llevados a cabo en Brasil. La prevalencia de la IPA varió de 18,7% a 90,6%, con una mediana de 79,7%. En todas las encuestas, la prevalencia fue mayor en las niñas que en los niños y y los países en desarrollo presentaron una mayor prevalencia. Conclusiones: Se concluye que la prevalencia de la IPA es alta entre los adolescentes y que la definición adoptada en este estudio se utiliza raramente en la literatura. Estos resultados sugieren que es necesario el desarrollo de intervenciones para aumentar los niveles de actividad física entre los adolescentes.

    Objetivo: Un estudio transversal se llevó a cabo con 1477 estudiantes de primaria matriculados en las escuelas públicas de Salvador, Bahía, Brasil, para evaluar la prevalencia del sobrepeso y la obesidad. Métodos: La muestra se determinó por la técnica de muestreo por conglomerados en dos etapas para la selección de escuelas y clases. Más tarde, posteriori error se calculó. Los estudiantes fueron clasificados como sobrepeso u obesos de acuerdo con la clasificación de la Organización Mundial de la Salud, 2007. Ellos también fueron clasificados de acuerdo a la edad, la etapa de maduración sexual, y la presencia de obesidad abdominal. Resultados: En general, el 9,3% de los estudiantes tenían sobrepeso y el 6,4% eran obesos, por lo tanto, el 15,7% de los alumnos se considera que tienen exceso de peso (sobrepeso + obesidad), con un intervalo de confianza del 95%. De la población total estudiada el 12,9% presentaron obesidad abdominal, esta condición se observa en el 13% de su peso normal. Se encontró asociación entre el sobrepeso y la edad < 14 AÑOs (p = 0,030) y obesidad abdominal (p = 0,001). Conclusiones: Los programas de intervención deben ser implementados para prevenir y tratar la obesidad en la infancia y la adolescencia. Además, los profesionales que trabajan con las personas en este grupo de edad deben ser sensibles a este problema. La necesidad de estandarizar los indicadores antropométricos utilizados en los diferentes estudios se enfatiza también.

Complete genome sequence of Planctomyces brasiliensis type strain (DSM 5305T), phylogenomic analysis and reclassification of Planctomycetes including the descriptions of Gimesia gen. nov., Planctopirus gen. nov. and Rubinisphaera gen. nov. and emended descriptions of the order Planctomycetales and the family Planctomycetaceae

    Planctomyces brasiliensis Schlesner 1990 belongs to the order Planctomycetales, which differs from other bacterial taxa by several distinctive features such as internal cell compartmentalization, multiplication by forming buds directly from the spherical, ovoid or pear-shaped mother cell and a cell wall consisting of a proteinaceous layer rather than a peptidoglycan layer. The first strains of P. brasiliensis, including the type strain IFAM 1448T, were isolated from a water sample of Lagoa Vermelha, a salt pit near Rio de Janeiro, Brasil. This is the second completed genome sequence of a type strain of the genus Planctomyces to be published and the sixth type strain genome sequence from the family Planctomycetaceae. The 6,006,602 bp long genome with its 4,811 protein-coding and 54 RNA genes is a part of the G enomic E ncyclopedia of Bacteria and Archaea project. Phylogenomic analyses indicate that the classification within the Planctomycetaceae is partially in conflict with its evolutionary history, as the positioning of Schlesneria renders the genus Planctomyces paraphyletic. A re-analysis of published fatty-acid measurements also does not support the current arrangement of the two genera. A quantitative comparison of phylogenetic and phenotypic aspects indicates that the three Planctomyces species with type strains available in public culture collections should be placed in separate genera. Thus the genera Gimesia, Planctopirus and Rubinisphaera are proposed to accommodate P. maris, P. limnophilus and P. brasiliensis, respectively. Pronounced differences between the reported G + C content of Gemmata obscuriglobus, Singulisphaera acidiphila and Zavarzinella formosa and G + C content calculated from their genome sequences call for emendation of their species descriptions. In addition to other features, the range of G + C values reported for the genera within the Planctomycetaceae indicates that the descriptions of the family and the order should be

    Antecedentes: En la mayoría de los países latinoamericanos existe una deficiencia de micronutrientes, retraso en el crecimiento, y altas tasas de morbilidad y mortalidad infantil. En la actualidad se ha asociado la deficiencia de zinc con el retraso del crecimiento infantil. El propósito de esta revisión, fue analizar artículos sobre estudios aleatorizados que evaluaron el efecto de la suplementación con zinc y el crecimiento infantil. Metodología: Se realizó una búsqueda electrónica de la literatura en la base de datos de PubMed con las palabras claves “Micronutrient supplementation and growth”, publicados de enero de 2005 a abril de 2013. Se identificaron 34 estudios aleatorizados controlados (EAC) realizados en Latinoamérica, de los cuales cinco reunieron los criterios de inclusión. Se añadió un estudio referido por otros autores. Resultados: Los estudios se realizaron en Brasil, Cuba, Perú, Ecuador, y Guatemala. En ningún estudio se observó el efecto positivo del zinc sobre el crecimiento lineal. Conclusión: La revisión realizada sugiere que la suplementación con zinc no tiene un efecto significativo sobre el crecimiento lineal; sin embargo, podría tener beneficios sobre el crecimiento en niños con deficiencia de zinc si se añaden otros nutrientes en deficiencia.

    Decreased heart rate variability (HRV) is a cardiovascular predictor of mortality. Recent debate has focused on whether reductions in HRV in major depressive disorder (MDD) are a consequence of the disorder or a consequence of pharmacotherapy. Here we report on the impact of transcranial direct current stimulation (tDCS), a non-pharmacological intervention, vs. sertraline to further investigate this issue. The employed design was a double-blind, randomized, factorial, placebo-controlled trial. One hundred and eighteen moderate-to-severe, medication-free, low-cardiovascular risk depressed patients were recruited for this study and allocated to either active/sham tDCS (10 consecutive sessions plus two extra sessions every other week) or placebo/sertraline (50 mg/d) for 6 wk. Patients were age and gender-matched to healthy controls from a concurrent cohort study [the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil)]. The impact of disorder, treatment and clinical response on HRV (root mean square of successive differences and high frequency) was examined. Our findings confirmed that patients displayed decreased HRV relative to controls. Furthermore, HRV scores did not change following treatment with either a non-pharmacological (tDCS) or pharmacological (sertraline) intervention, nor did HRV increase with clinical response to treatment. Based on these findings, we discuss whether reduced HRV is a trait-marker for MDD, which may predispose patients to a host of conditions and disease even after response to treatment. Our findings have important implications for our understanding of depression pathophysiology and the relationship between MDD, cardiovascular disorders and mortality.

  8. Experimental study of a single channel alluvial fan

    At the outlet of mountain ranges, rivers reach a flat plain and start to depose their sediment load into a conical sedimentary structure called alluvial fan. To decipher these sedimentary records, we need to understand the dynamics of their growth. Most natural fans are built by braided streams. However, to avoid the complexity of braided rivers, we develop a small-scale experiment in which an alluvial fan is formed by a single channel. We use a mixture of water and glycerol to produce a laminar river. The fluid is mixed with corindon sand (~ 300 μm) in a tilted channel and left free to form a fan around its outlet. The sediment and water discharges are constant during an experimental run. We record the fan progradation and the channel morphology with top-view pictures. We also generate an elevation map with an optical method based on the deformation of a moiré pattern. We observe that, to leading order, the fan remains self-affine as it grows, with a constant slope. We compare two recent studies about the formation of one-dimensionnal fan [Guerit et al. 2014] and threshold rivers [Seizilles et al. 2013] to our experimental findings. In particular, we propose a theory witch relates the fan morphology to the control parameters (fluid and sediment discharges, grain size). Our observations accord with the predictions, suggesting that the fan is built near the threshold of sediment motion. At the first order, the fan profile is linear and control by the water discharge. The downstream decrease in sediment discharge add a curvature to this profile. Finally, we intend to expand our interpretation to alluvial fans build by single-thread channels ( Okavango, Bostwana; Taquari and Paraguay, Brasil).

    For the past few years, the U.S. Unidata Program Center (Unidata, a program in UCAR) and Brazil's Centro de Previsão de Tempo e Estudos Climáticos (CPTEC, a division of INPE) have collaborated in outreach efforts where free-and-open exchange of hydro-meteorological data and the provision of free analysis/visualization tools are helping to build a hemispheric community where data, tools, and best practices in education and research are shared. Data sharing capabilities are being provided by Unidata's Internet Data Distribution (IDD) system, a community-based effort that has been the primary source of real-time meteorological data in the U.S. university community for over a decade. Unidata-CPTEC efforts have resulted in the creation of the Brazilian peer of the North American IDD, the IDD-Brasil, a data sharing network that has extended access to real-time data to over 15 institutions in South America and most recently countries in West Africa and the African Sahel. UCAR and CPTEC are involved in separate, but philosophically-related and complementary outreach efforts in Africa: UCAR has embarked on an effort, The UCAR Africa Initiative, whose goal is assisting in building sustainable atmospheric-sciences capacity in Africa. CPTEC is collaborating with national weather services in three West African countries, universities in Brazil and Portugal, and one private Portuguese company in SICLIMAD, a project aimed at contributing to sustainable development in West Africa. This presentation will provide an overview of the efforts being undertaken as part of The UCAR Africa Initiative; an overview and update on CPTEC's efforts in SICLIMAD; and explore avenues for greater collaboration on African issues and endeavors.

    Observations of upward lightning from tall objects have been reported since 1939. Interest in this subject has grown recently, some of it because of the rapid expansion of wind power generation. Also, with the increasing number of tall buildings and towers, there will be a corresponding increase in the number of upward lightning flashes from these structures. Reports from recent field observations are beginning to address the nature of upward lightning initiation, but much still needs to be learned. Examples are studies of upward lightning from towers in winter thunderstorms in Japan (Wang and Takagi, 2010; and Lu et al., 2009) and summer thunderstorms in Europe (Miki et al., 2005; Flache et al., 2008; and Diendorfer et al., 2009; Zhou et al., 2011) and in North America (Mazur and Ruhnke, 2011; Hussein et al., 2011; Warner, 2011, and Warner et al., 2011). Up to January 2012, no upward flash had ever been registered in Brazil. With the help of some video cameras, we recorded 15 upward lightning which started from one of the towers located on Peak Jaraguá in the city of São Paulo. This paper describes the first results of this field campaign. A combination of high-speed video and standard definition video were used to record upward lightning flashes from multiple towers in Sao Paulo, Brazil, a city located in southeastern Brazil with a population over 10 million people, an average elevation of around 800 meters above sea level, and a flash density of 15 flashes/km2/year. Observations of 15 upward flashes made with these assets were analyzed along with BrasilDAT Lightning Detection Network and a lightning mapping array (LMA) and electric field sensors.

    The Lagoa Real uranium district in Bahia, northeastern Brazil, is the most important uranium province in the country and presently produces this metal in an open-pit mine operated by Indústrias Nucleares do Brasil. Uranium-rich zones are associated with plagioclase (dominantly albite ± oligoclase) -rich rocks, albitites and metasomatized granitic-gneisses, distributed along NNW/SSE striking shear zones. We have used the ID-TIMS U-Pb method to date zircon and titanite grains from the São Timóteo granitoid, and albite-rich rocks from the Lagoa Real district in order to assess the age of granite emplacement, deformation/metamorphism and uranium mineralization. The isotopic data support the following sequence of events (i) 1746 ± 5 Ma - emplacement of the São Timóteo granitoid (U-Pb zircon age) in an extensional setting, coeval with the beginning of the sedimentation of the Espinhaço Supergroup; (ii) 956 ± 59 Ma hydrothermal alteration of the São Timóteo granitoid and emplacement of the uranium mineralization (U-Pb titanite age on an albite-rich sample); (iii) 480 Ma metamorphism, remobilization and Pb loss (U-Pb titanite age for the gneiss sample), during the nucleation of shear zones related to the collision between the São Francisco-Congo and Amazonia paleoplates. The 956 ± 59-Ma mineralization age is apparently associated with the evolution of the Macaúbas-Santo Onofre rift. This age bracket may bear an important exploration implication, and should be included in the diverse age scenario of uranium deposits worldwide.

    We report on the discovery of seven low-metallicity stars selected from the Hamburg/ESO Survey, six of which are extremely metal-poor (EMP, [Fe/H] <= -3.0), with four having [Fe/H] <= -3.5. Chemical abundances or upper limits are derived for these stars based on high-resolution (R ~ 35,000) Magellan/MIKE spectroscopy, and are in general agreement with those of other very and extremely metal-poor stars reported in the literature. Accurate metallicities and abundance patterns for stars in this metallicity range are of particular importance for studies of the shape of the metallicity distribution function of the Milky Way's halo system, in particular for probing the nature of its low-metallicity tail. In addition, taking into account suggested evolutionary mixing effects, we find that six of the program stars (with [Fe/H] <= -3.35) possess atmospheres that were likely originally enriched in carbon, relative to iron, during their main-sequence phases. These stars do not exhibit overabundances of their s-process elements, and hence may be, within the error bars, additional examples of the so-called CEMP-no class of objects.

    This is the second in a series of papers studying the variable stars in Large Magellanic Cloud globular clusters. The primary goal of this series is to study how RR Lyrae stars in Oosterhoff-intermediate systems compare to their counterparts in Oosterhoff I/II systems. In this paper, we present the results of our new time-series B-V photometric study of the globular cluster NGC 1786. A total of 65 variable stars were identified in our field of view. These variables include 53 RR Lyraes (27 RRab, 18 RRc, and 8 RRd), 3 classical Cepheids, 1 Type II Cepheid, 1 Anomalous Cepheid, 2 eclipsing binaries, 3 Delta Scuti/SX Phoenicis variables, and 2 variables of undetermined type. Photometric parameters for these variables are presented. We present physical properties for some of the RR Lyrae stars, derived from Fourier analysis of their light curves. We discuss several different indicators of Oosterhoff type which indicate that the Oosterhoff classification of NGC 1786 is not as clear cut as what is seen in most globular clusters.

    We report on an analysis of 308.3 hr of high-speed photometry targeting the pulsating DA white dwarf EC14012-1446. The data were acquired with the Whole Earth Telescope during the 2008 international observing run XCOV26. The Fourier transform of the light curve contains 19 independent frequencies and numerous combination frequencies. The dominant peaks are 1633.907, 1887.404, and 2504.897 μHz. Our analysis of the combination amplitudes reveals that the parent frequencies are consistent with modes of spherical degree l = 1. The combination amplitudes also provide m identifications for the largest amplitude parent frequencies. Our seismology analysis, which includes 2004-2007 archival data, confirms these identifications, provides constraints on additional frequencies, and finds an average period spacing of 41 s. Building on this foundation, we present nonlinear fits to high signal-to-noise light curves from the SOAR 4.1 m, McDonald 2.1 m, and KPNO 2 m telescopes. The fits indicate a time-averaged convective response timescale of τ0 = 99.4 ± 17 s, a temperature exponent N = 85 ± 6.2, and an inclination angle of θ i = 32fdg9 ± 3fdg2. We present our current empirical map of the convective response timescale across the DA instability strip.

    We present a spectroscopic and photometric determination of the distance to the young Galactic open cluster Westerlund 2 using WFPC2 imaging from the Hubble Space Telescope (HST) and ground-based optical spectroscopy. HST imaging in the F336W, F439W, F555W, and F814W filters resolved many sources previously undetected in ground-based observations and yielded photometry for 1136 stars. We identified 15 new O-type stars, along with two probable binary systems, including MSP 188 (O3 + O5.5). We fit reddened spectral energy distributions based on the Padova isochrones to the photometric data to determine individual reddening parameters RV and AV for O-type stars in Wd2. We find average values langRV rang = 3.77 ± 0.09 and langAV rang = 6.51 ± 0.38 mag, which result in a smaller distance than most other spectroscopic and photometric studies. After a statistical distance correction accounting for close unresolved binaries (factor of 1.08), our spectroscopic and photometric data on 29 O-type stars yield that Westerlund 2 has a distance langdrang = 4.16 ± 0.07 (random) +0.26 (systematic) kpc. The cluster's age remains poorly constrained, with an upper limit of 3 Myr. Finally, we report evidence of a faint mid-IR polycyclic aromatic hydrocarbon ring surrounding the well-known binary candidate MSP 18, which appears to lie at the center of a secondary stellar grouping within Westerlund 2.

    In Argentina, there is no record of human cases produced by Dengue virus (Flavivirus), but Paraguay and Brasil (neighbouring countries) have notified human outbreaks of Dengue Haemorrhagic Fever. In this report, we inform the serological results of a limited human outbreak of a Dengue-like acute illness that occurred in General Belgrano Island, Formosa, Argentina in April 1989. This island is 35 km far from Clorinda city of Paraguay river, with a human population of 150 inhabitants. The weather of this area is humid with abundant rainfall, favouring mosquitoes proliferation. Two samples of serum from 28 human notified cases were studied using hemagglutination inhibition test (HI), complement fixation (CF), and plaque reduction neutralization (NT) test in Vero cell cultures. All tested sera were negative to Dengue, St. Louis encephalitis, Yellow Fever, Bussuquara, Rocio, Eastern and Western Equine Encephalitis arboviruses as well as Influenza and Rubella viruses. By contrast, infection with Venezuelan equine encephalitis virus (VEE), subtype VI-AG80-663 strain was demonstrated (34.5% positive by HI, 39.1% by CF and 51.6% by NT). Seroconversion was detected by NT in six cases and only five were positive by CF. The 26.8% of the sera reacted also with VEE subtype I AB by NT. Considering that no cross reaction were detected in NT with these two subtypes, our results suggest that both viruses are concomitantly circulating in the studied area. Furthermore, the seroconversions detected with AG80-663 strain firmly indicate that during the outbreak this virus subtype was circulating in the island, although we could not assure that it was the causal agent of the acute disease.

    Recent increases in the price of oil have generated much interest in biofuel development. Despite the increasing demand, the social and environmental impacts of large scale adoption of biofuels at both regional and national scales remain understudied, especially in developing economies. Here we use municipality-level data for the state of São Paulo in Brasil to explore the effects of fires associated with sugarcane cultivation on respiratory health of elderly and children. We examined the effects of fires occurring in the same year in which respiratory cases were reported as well as chronic effects associated with long-term cultivation of sugarcane. Across the state, respiratory morbidity attributable to fires accounted for 113 elderly and 317 child cases, approximately 1.8% of total cases in each group. Although no chronic effects of fire were detected for the elderly group, an additional 650 child cases can be attributed to the long term cultivation of sugar cane increasing to 5.4% the percent of children cases that can be attributed to fire. For municipalities with greater than 50% of the land in sugarcane the percentage increased to 15% and 12 % respectively for elderly and children. An additional 209 child cases could also be attributed to past exposure to fires associated with sugarcane, suggesting that in total 38% of children respiratory cases could be attributed to current or chronic exposure to fires in these municipalities. The harmful effects of cane- associated fires on health are not only a burden for the public health system but also for household economies. This type of information should be incorporated into land use decisions and discussions of biofuel sustainability.

    Introducción: El propósito de esta revisión fue analizar los estudios sobre anuncios de alimentos en la TV en Latinoamérica y en los EEUU dirigidos a Hispanos. Métodos: Se realizó una búsqueda electrónica de trabajos publicados de 1986 a 2015, en las bases de datos de MEDLINE/PubMed, EMBASE, SCIELO, y CINAHL, en internet de acceso abierto, sobre anuncios de alimentos en la televisión dirigidos a niños en países latinoamericanos y a Hispanos que viven en los Estados Unidos. Resultados: La búsqueda dio como resultado veinticuatro estudios, seis realizados en Chile, cinco en México, cuatro en Brasil, tres en Hispanos de EEUU, y uno en cada uno de los siguientes países: Argentina, Perú, Colombia, Honduras y Venezuela. Una gran proporción de anuncios sobre alimentos en la TV están dirigidos a los niños y a sus familias. Esta exposición ha sido asociada a la preferencia y solicitud de compra de estos alimentos por los niños y con un aumento del IMC, sobrepeso y obesidad en niños y adultos. Conclusión: Se observa una alarmante alta exposición de anuncios de alimentos en la TV dirigida a niños, lo que demanda políticas regulatorias, supervisión, y rendimiento de cuentas eficaces.

    The occurrence and intensity of the geomagnetic pulsations Pc-5 (2-7 mHz) and its relationship with the solar cycle in the South Atlantic Magnetic Anomaly -SAMA is presented. The study of geomagnetic pulsations is important to help the understanding of the physical processes that occurs in the magnetosphere region and help to predict geomagnetic storms. The fluxgate mag-netometers H, D and Z, three axis geomagnetic field data from the Southern Space Observatory -SSO/CRS/INPE -MCT, São Martinho da Serra (29.42° S, 53.87° W, 480m a.s.l.), RS, Brasil, a were analyzed and correlated with the solar wind parameters (speed, density and temperature) from the ACE and SOHO satellites. A digital filtering to enhance the 2-7 mHz geomagnetic pulsations was used. Five quiet days and five perturbed days in the solar minimum and in the solar maximum were selected for this analysis. The days were chosen based on the IAGA definition and on the Bartels Musical Diagrams (Kp index) for 2001 (solar maximum) and 2008 (solar minimum). The biggest Pc-5 amplitude averages differences between the H-component is 78,35 nT for the perturbed days and 1,60nT for the quiet days during the solar maximum. For perturbed days the average amplitude during the solar minimum is 8,32 nT, confirming a direct solar cycle influence in the geomagnetic pulsations intensity for long periods.

    We report the results of our exploratory program carried out with the southern Astrophysical Research telescope aimed at associating counterparts and establishing the nature of the Fermi Unidentified γ-ray Sources (UGSs). We selected the optical counterparts of six UGSs from the Fermi catalog on the basis of our recently discovered tight connection between infrared and γ-ray emission found for the γ-ray blazars detected by the Wide-Field Infrared Survey Explorer in its all-sky survey. We perform for the first time a spectroscopic study of the low-energy counterparts of the Fermi UGSs, in the optical band, confirming the blazar-like nature of the whole sample. We also present new spectroscopic observations of six active galaxies of uncertain type associated with Fermi sources which appear to be BL Lac objects. Finally, we report the spectra collected for six known γ-ray blazars belonging to the Roma BZCAT that were obtained to establish their nature or better estimate their redshifts. Two interesting cases of high redshift and extremely luminous BL Lac objects (z ≥ 1.18 and z ≥ 1.02, based on the detection of Mg ii intervening systems) are also discussed.

    Magnetospheric observational proxies are used for indirect detection of magnetic fields in hot stars in the X-ray, UV, optical, and radio wavelength ranges. To determine the viability of infrared (IR) hydrogen recombination lines as a magnetic diagnostic for these stars, we have obtained low-resolution (R~ 1200), near-IR spectra of the known magnetic B2V stars HR 5907 and HR 7355, taken with the Ohio State Infrared Imager/Spectrometer (OSIRIS) attached to the 4.1 m Southern Astrophysical Research (SOAR) Telescope. Both stars show definite variable emission features in IR hydrogen lines of the Brackett series, with similar properties as those found in optical spectra, including the derived location of the detected magnetospheric plasma. These features also have the added advantage of a lowered contribution of stellar flux at these wavelengths, making circumstellar material more easily detectable. IR diagnostics will be useful for the future study of magnetic hot stars, to detect and analyze lower-density environments, and to detect magnetic candidates in areas obscured from UV and optical observations, increasing the number of known magnetic stars to determine basic formation properties and investigate the origin of their magnetic fields.

    Aims: We present and analyse late-time observations of the Type-Ib supernova with possible pre-supernova progenitor detection, iPTF13bvn, which were done ~300 days after the explosion. We discuss them in the context of constraints on the supernova's progenitor. Previous studies have proposed two possible natures for the progenitor of the supernova, i.e. a massive Wolf-Rayet star or a lower-mass star in a close binary system. Methods: Our observations show that the supernova has entered the nebular phase, with the spectrum dominated by Mg I]λλ4571, [O I]λλ6300, 6364, and [Ca II]λλ7291, 7324 emission lines. We measured the emission line fluxes to estimate the core oxygen mass and compared the [O I]/[Ca II] line ratio with other supernovae. Results.The core oxygen mass of the supernova progenitor was estimated to be ≲0.7 M⊙, which implies initial progenitor mass that does not exceed ~15-17 M⊙.Since the derived mass is too low for a single star to become a Wolf-Rayet star, this result lends more support to the binary nature of the progenitor star of iPTF13bvn. The comparison of [O I]/[Ca II] line ratio with other supernovae also shows that iPTF13bvn appears to be in close association with the lower mass progenitors of stripped-envelope and Type-II supernovae.

    A Astronomia é um tema que sempre exerceu fascínio sobre as pessoas de um modo geral. Conhecer e estudar o que há nos “céus”, além de nossos olhos, continua sendo instigador e de grande interesse. Baseado nestas justificativas desenvolveu-se uma pesquisa de Doutorado, na qual, o objetivo principal foi investigar sobre a presença dos conteúdos de Astronomia nas Propostas Curriculares da região Sul do Brasil, a saber, os estados de Paraná, Rio Grande do Sul e Santa Catarina e, posterior comparação com os Parâmetros Curriculares Nacionais (PCN) que trazem propostas de conteúdos para toda a Educação Básica brasileira. Tal investigação pautou-se na abordagem de caráter qualitativo e utilizouse para tal da Análise de Conteúdos (Bardin, 2011), que possibilitou a construção de quatro categorias, nas quais os conteúdos astronômicos foram agrupados: Terra, Sistema Solar, Via Láctea e Universo. Após a leitura, coleta de dados, construção de categorias, observou-se a dicotomia na apresentação destes conteúdos. As propostas curriculares analisadas foram as de Geografia, Ciências e Física dos estados do Paraná (2008), Rio Grande do Sul (2009) e de Santa Catarina (1998), responsáveis pelo trabalho com Astronomia nestes estados. No Ensino Fundamental, a proposta curricular do estado do Paraná apresenta conteúdos ligados à Astronomia desde o sexto ano até o nono ano, como conteúdo do primeiro bimestre, o que também é apresentado na proposta curricular do estado do Rio Grande do Sul, porém, este, não divide os conteúdos por bimestre e nem por ano, mas por ciclos, sexto e sétimo anos como primeiro ciclo e oitavo e nono anos como segundo ciclo, deixando livre para o professor estruturar sua sequência de conteúdos. A proposta curricular de Santa Catarina não apresenta estes conteúdos de maneira explícita, não divide dos conteúdos nem por ano, nem por série, traz uma sequência de conteúdos para serem trabalhados ao longo dos

    La úlcera por presión (UP) es una lesión localizada en la piel y/o tejido subyacente, generalmente sobre prominencias óseas, provocada por la presión y/o asociada a cizallamiento. Aunque evitable, todavía es muy prevalente, siendo destacable que en su etiología están involucrados múltiples factores. Objetivo: identificar la incidencia de úlceras por presión y los factores demográficos, clínicos y nutricionales asociados en pacientes internados en la UCI de un hospital universitario. Métodos: estudio prospectivo, observacional, con pacientes internados en una UCI de un hospital universitario ubicado en el nordeste brasileño, durante el periodo de junio a noviembre de 2014. Se determinó la UP a través de la inspección corporal tres veces a la semana durante el baño matinal, con base en las características establecidas por la National Pressure Ulcer Advisory Panel, 2014. Se recolectaron datos demográficos, clínicos, bioquímicos y nutricionales. Se utilizó la escala de Braden para verificar a los individuos con riesgo de desarrollo de UP. Resultados: la muestra se compuso de 51 pacientes, con un promedio de edad de 57,7(± 16,4) años. Se verificó una incidencia de UP del 52,9%, y los factores asociados a su desarrollo fueron: uso de droga vasoactiva (p = 0,029), tiempo de hospitalización > 10 días (p ≤ 0,001) y ausencia de anemia (p = 0,011). Conclusión: la elevada incidencia de UP resalta la vulnerabilidad de los pacientes en cuidados intensivos. A pesar de caracterizarse por ser una condición multifactorial, solo el uso de drogas vasoactivas, el tiempo de hospitalización y la ausencia de anemia se asociaron a la aparición de UP. Factores nutricionales y clínicos frecuentemente relacionados a las lesiones se asociaron con su desarrollo.

    Introducción: la elección del método para la evaluación nutricional es fundamental para el correcto seguimiento del estado nutricional de los pacientes sometidos al trasplante de hígado.Objetivos: evaluar y comparar el estado nutricional de los pacientes antes y después del trasplante de hígado por el tiempo de un año para los diferentes métodos de evaluación nutricional.Métodos: se evaluaron los pacientes que se sometieron a un trasplante de hígado en diferentes momentos: pretrasplante, 1, 3, 6 y 12 meses después del procedimiento, en la Hermandad de la Santa Casa de Porto Alegre, Porto Alegre, RS, Brasil. Los métodos utilizados fueron la antropometría, la fuerza de apretón de manos por la fuerza de agarre no dominante (FAM), el espesor del músculo aductor del pulgar y el ángulo de fase (AF) por bioimpedancia eléctrica (BIA). En todas las evaluaciones se tomaron las mismas medidas.Resultados: las evaluaciones se llevaron a cabo en 22 pacientes. Los métodos que mostraron mayor prevalencia de pacientes desnutridos antes del trasplante fueron la FA por BIA (25%), la circunferencia muscular del brazo (CMB) (21,9%) y la circunferencia del brazo (CB) (18,8%). Al comparar el estado nutricional de los pacientes durante el seguimiento, hubo diferencia significativa en los métodos de evaluación de CB, espesor del pliegue cutáneo triciptal y AF por la BIA. Al final del seguimiento, los métodos de evaluación nutricional fueron nuevamente comparados y mostraron de diferencias significativas, siendo la FAM el método de mayor detección de desnutrición.Conclusiones: se sugiere que podría intensificarse el uso del método AF por la BIA en esta población, ya que los resultados están en consonancia con los encontrados en la literatura, siendo significativos, fiables y reproducibles.

    Introducción: Brasil es el segundo país del mundo con el mayor número de gimnasios y actualmente representa aproximadamente 30 mil unidades. Cada vez hay más evidencias de que una parte significativa de los practicantes de actividad física desarrollan un compromiso exagerado con esta actividad, que incluso pueden generar dependencia patológica. Objetivo: determinar la asociación entre la práctica exagerada de ejercicio físico (ED) y el consumo de suplementos entre los practicantes. Método: se utilizó la escala de adicción al ejercicio en practicantes mayores de 19 años, de ambos sexos. Fue realizada una entrevista individual para determinar históricamente el consumo de suplementos; también se evaluaron los resultados de antropometría y la frecuencia departicipación en el gimnasio. Resultados: la frecuencia de la práctica en el gimnasio fue del 66,5% y la prevalencia de la suplementación fue de 51,5%, la posibilidades de un adicto al ejercicio ser un consumidor de suplemento se estima en 4,53. Conclusión: la relación entre la adicción al ejercicio y el consumo de suplemento fue comprobada, constituyendo una alerta para los profesionales de la salud, que deben tener en cuenta los factores de riesgo para el desarrollo de los signos más graves y síntomas, incluyendo el control de peso obsesivo por medio de la práctica intensa de ejercicios físicos, consumo de dietas inadecuadas y uso de suplementos nutricionales. Se recomienda que la evaluación nutricional se complemente de otras determinaciones para detectar la adicción al ejercicio y el uso de suplementación nutricional. Si es necesario, se pueden promover campañas para avalar las dietas consumidas, la composición corporal ideal y detectarlos cambios drásticos en la alimentación, así como otras cuestiones relacionadas con el cuidado nutricional en general.

    Objetivo: Investigar la prevalencia y los factores asociados con el sobrepeso y la obesidad en niños menores de 5 años en el estado de Alagoas, al noreste de Brasil. Diseño: Estudio poblacional transversal. El estudio se basó en 1.115 niños con una edad promedio de 24,7 meses (DE ± 16,8), de los que el 51,7% eran niñas. El estado nutricional se clasificó según el IMC / edad. El score > + 1 and ≤+2 z identificaba a los niños con sobrepeso y aquellos con un score > + 2 z a aquellos con obesidad, en función de la referencia estándar de la Organización Mundial de la Salud. Para identificar las variables asociadas con el sobrepeso y la obesidad se realizó un análisis de regresión de Poisson. Resultados: La prevalencia de sobrepeso y obesidad fue del 23,9% y del 7,8%, respectivamente, del 33,8% en las niñas y del 29,4% en los niños. Tras el ajuste, la renta per cápita igual o superior a 2,5 veces el salario mínimo, la edad de 6 a 23 meses y el sobrepeso y la obesidad maternos seguían asociándose positivamente con el sobrepeso/obesidad. Por otro lado, se observó una asociación negativa entre el peso al nacimiento bajo o insuficiente con el sobrepeso/ obesidad infantil. Conclusiones: Los resultados muestran una prevalencia similar de sobrepeso y obesidad a la de otros estudios en este país para los niños menores de 5 años, alertando de una posible alteración del crecimiento y desarrollo del niño.

    Introducción: la ingestión inadecuada de alimentos puede comprometer la salud cardiovascular de la persona, lo que aumenta las posibilidades de desarrollar una serie de enfermedades. La relación entre la ingesta dietética inadecuada y ciertos factores de riesgo cardiovascular en poblaciones de adultos jóvenes no está clara. Objetivos: el objetivo de este estudio fue investigar la asociación entre los hábitos alimentarios de los estudiantes universitarios, el exceso de peso corporal, la presión arterial alta y la actividad física regular. Material y métodos: se realizó un estudio de corte transversal analítico en estudiantes de una universidad federal brasileña. Se incluyeron 1.599 estudiantes de entre 18 y 25 años. Se aplicó una encuesta tipo entrevista que incluía variables sociodemográficas y el Cuestionario Internacional de Actividad Física (IPAQ). Posteriormente, se realizó la valoración de la composición corporal (talla, peso, índice de masa corporal (IMC), circunferencia de la cintura (CC)). Los hábitos alimentarios y las conductas de riesgo cardiovascular se evaluaron mediante el cuestionario YRBSS-C (Youth Risk Behavior Surveillance). Resultados: utilizando la prueba de chi-cuadrado, se encontró una asociación entre el consumo excesivo de alcohol, el consumo de frutas y el consumo de ensaladas/ verduras con actividad física regular. También se observó la asociación entre el consumo de dulces y salados, con el IMC y la circunferencia de la cintura alta. La regresión logística mostró asociación entre la ingesta de dulces (odds = 1,34) y salados (odds = 1,39) con el IMC alto. También mostró asociación con la circunferencia de la cintura, el consumo de dulces (odds = 1,33) y salados (odds = 1,74). La AFMV estaba relacionada con el consumo excesivo de alcohol (odds = 1,23), el consumo de frutas (1,46) y el consumo de ensaladas/verduras (odds = 1,49). De este modo, se comprobó la asociación entre la conducta alimentaria de

    Environmental modification by anthropogenic actions, disordered urban growth, globalization of international exchange and climate change are some factors that help the emergence and dissemination of human infectious diseases transmitted by vectors. This review discusses the recent entry of three arboviruses in Brazil: Chikungunya, West Nile, and Zika virus, focusing on the challenges for the Country's public health. The Brazilian population is exposed to infections caused by these three arboviruses widely distributed on the national territory and associated with humans. Without effective vaccine and specific treatment, the maintainance and integration of a continuos entomological and epidemiological surveillance are important so we can set methods to control and prevent these arboviruses in the Country. RESUMO A modificação do ambiente por ações antrópicas, o crescimento urbano desordenado, o processo de globalização do intercâmbio internacional e as mudanças climáticas são alguns fatores que vêm facilitando a emergência e disseminação de doenças infecciosas humanas transmitidas por vetores. Este comentário aborda a recente entrada de três arbovírus no Brasil, Chikungunya (CHIKV), West Nile (WNV) e Zika (ZIKV), com enfoque nos desafios para a Saúde Pública do País. Transmitidos por mosquitos vetores amplamente distribuídos no território nacional e associados ao homem, a população brasileira encontra-se exposta à infecção por esses três arbovírus. Na ausência de vacina eficaz e tratamento específico, são importantes a manutenção e integração de uma vigilância entomológica e epidemiológica contínua, a fim de direcionarmos métodos de controle e prevenção contra essas arboviroses no País.

    Introducción: la investigación de los resultados previa en cirugía bariátrica tiene que documentar los cambios positivos en las comorbilidades asociadas a la obesidad. Objetivo: el objetivo del estudio fue informar de una descripción de los efectos de la cirugía bariátrica sobre la pérdida de peso y en la resolución de enfermedades asociadas con la obesidad en pacientes seguidos durante 12 meses en el servicio de salud pública de São Paulo/Brasil. Métodos: el estudio se realizó con los datos de 598 pacientes seleccionados con obesidad grado III sometidos a bypass gástrico en Y de Roux evaluados antes y 6 y 12 meses después de la cirugía. En cada momento se determinaron la antropometría, los datos demográficos y bioquímicos y la historia personal. La glucosa sérica, el colesterol total, el colesterol LDL, el colesterol HDL y los triglicéridos fueron determinados en la evaluación bioquímica. Los datos fueron analizados estadísticamente por el test de Chi-cuadrado, por ANOVA seguido por el post-test de Bonferroni y por la prueba t de Student para datos independientes; significación fijada en p < 0,05. Resultados: se observó pérdida de peso de 45,5 ± 13,7 kg (33,5%) durante el primer año después de la cirugía. Glucosa sérica, colesterol total y colesterol LDL se redujeron durante los primeros seis meses después de la cirugía y los valores se mantuvieron hasta los 12 meses, mientras que el peso y los triglicéridos se redujeron en todo el período de estudio. Se observó una prevalencia reducida de diabetes mellitus y dislipidemia después de la cirugía (p < 0,001). Conclusiones: el bypass gástrico en Y de Roux es un procedimiento importante para la pérdida de peso y el control de las comorbilidades como la diabetes y la dislipidemia, al menos durante el primer año postoperatorio.

    Introducción: La caquexia es un síndrome multifactorial caracterizada por la pérdida de peso corporal, grasa y músculo, el aumento de la morbilidad y la mortalidad. El uso de un índice de la contabilidad para los dos niveles de albúmina sérica y la proteína C reactiva podría hacer que la identificación temprana de la caquexia más fácil. Objetivo: Evaluar la variación de una índice inflamatorio- nutricional en relación con el estado nutricional en pacientes con cáncer. Métodos: Estudio descriptivo incluyendo pacientes con cáncer gastrointestinal y los pulmones de un servicio de la quimioterapia pública en Brasil. La albumina y la proteína C reactiva fueron medidos y el estado nutricional se definió por la Evaluación Global Subjetiva. Los análisis estadísticos se realizaron utilizando Stata 9.2(TM). Resultados: Un total de 74 pacientes fueron evaluados, el 58,1% de ellos fueron hombres y el promedio de 63,4 ± 11,9 2013s de edad. Cáncer gastrointestinal era el tipo más frecuente (71,6%). Sólo el 13,7% de los pacientes estaban bien nutridos y el 21,9% estaban gravemente desnutridos. Proteína C reactiva aumentaron significativamente de acuerdo a la declinación del estado nutricional (p=0,03). Cuando la albúmina de los pacientes con inflamación sistémica se evaluó, no hubo variación significativa en relación al estado nutricional (p=0,06). El índice inflamatorio-nutricional varió significativamente en relación al estado nutricional independiente de la inflamación sistémica (p=0,02). Conclusiones: El índice inflamatorio-nutricional puede ser una manera adyuvante para la evaluación nutricional bioquímica y seguimiento en los pacientes con cáncer y la inflamación sistémica.

    The importance of the textbooks in classrooms is revealed when studies are pointing that these pedagogical sources are, most of the times, the only source used by the elementary school teachers when preparing their Science lessons. When we analyzed the Astronomy contents in the textbooks approved by the Brazilian Textbook Program 2008 and which, in theory, are the best available in the Brazilian editorial market, we examined some categories in the 2008 Textbook Guide. This research characterizes the frequency of Astronomical contents appearing in the texts, in the pictures, and in the hands-on activities. Additionally, it describes some misconceptions and presents additional information on the collections. La importancia de los libros de texto en las aulas se pone de manifiesto cuando los estudios indican que este recurso educativo es a menudo la única fuente de consulta utilizada por el profesor de ciencias de la escuela primaria para preparar sus lecciones.

    The Trans-Saharan Borborema (TSB) belt is a product of the assembly of Gondwana, a supercontinent that formed from cratonic fragments derived from Rodinia and other vagrant lithospheric blocks. Recent reconstructions show the West African craton (WAC) and Congo- San-Francisco craton juxtaposed by the closure of the Brasiliano (Pharuside, Adamastor) ocean during early stages of the Pan-African orogenic cycle in northwest Gondwana. The Dahomeyide and Pharuside segments of the resulting orogenic belt preserve well- organized lithotectonic units on the eastern margin of the WAC. The foreland units consist of craton-verging nappe stacks formed from the deformed margin of the WAC and its cover rocks. The near-hinter land is underlain by granitoid gneisses postulated to represent ca 600 Ma juvenile crust, exposed in the Accra-Benin plain. Further east from the suture zone is the Nigerian province, which includes rocks that were extensively reworked apparently during the Pan-African. The Borborema province of northeastern Brasil is the correlative/ extension of Nigerian. It is underlain by rocks intensively reworked during the Brasiliano (Pan-African) orogeny and juxtaposed along a series of shear zones. A distinct feature of the TBS are these extensive shear zones, many of which are typified by dextral wrench shear. In West Africa the prominent examples extend from the Sahara to the coastline and include the Hoggar, which splays into the Kandi fault, which itself has numerous splays in Benin, Togo and southeastern Ghana. In Brazil, nearly all reconstructions show that the continuation of the Kandi Fault is the Sobral fault which is inferred to be the northern segment of the Trans-Brasiliano lineament (TBL). If correct, the TBL and its TBS extensions constitute a 4000 km long dextral shear zone, perhaps the longest coherent shear zone on earth. We suggest that the geometry of these shear zones and associated Pan African sutures have instructive analogs in the Tibet

    Introducción: el estado nutricional previo al trasplante de células madre hematopoyéticas (HSCT) afecta al pronóstico: los pacientes con una mejor nutrición necesitan un menor tiempo de injerto, mientras que una nutrición pobre estaría asociada a un aumento de la tasa de mortalidad, complicaciones, costes médicos, mala calidad de vida y hospitalización. Además, los pacientes con bajo peso presentan un mayor riesgo de muerte al principio del periodo post-HSCT, y la tasa de mortalidad sin recaída es mayor en aquellos con bajo peso extremo, sobrepeso y obesidad. La obesidad está relacionada con una toxicidad asociada al tratamiento, una incidencia más alta de enfermedad de injerto-huésped de grado II-IV (GVHD), infecciones y mortalidad. El objetivo de este estudio fue investigar el estado nutricional de pacientes que se sometieron a HSCT entre 2007 y 2013 en un hospital privado, calculando el índice de masa corporal (IMC), para comprobar la prevalencia de posibles desajustes nutricionales, especialmente obesidad. Métodos: en este estudio retrospectivo, basado en informes médicos, analizamos datos de todos los pacientes con enfermedades tumorales y no tumorales que se sometieron a HSCT desde enero de 2007 hasta febrero de 2014 en el Centro de hematología-oncología y trasplante de médula ósea en un gran centro de especialidades médicas en Brasil. Resultados: en el periodo se trató y analizó un total de 257 casos, de los cuales el 79% tenían edades de hasta 65 años. Entre estos, el 56% tenían sobrepeso u obesidad. Observamos una mayor prevalencia de obesidad en pacientes ancianos (P < 0,001). El IMC medio de la muestra total fue 26,4 kg/m2. El IMC fue significativamente diferente entre géneros, con una prevalencia mayor de sobrepeso entre los hombres (P < 0,001). Conclusión: a diferencia de otros estudios, nuestra investigación ha mostrado bajas tasas de tasas de bajo peso y altas tasas de sobrepeso y de obesidad en los hombres y pacientes

    Objetivo: Identificar el estado nutricional de los pacientes con cáncer gastrointestinal y verificar su asociación con características demográficas y clínicas. Métodos: Se realizó un estudio transversal, con un diseño de muestreo no probabilístico. Los participantes fueron 143 pacientes adultos con cáncer gastrointestinal, que reciben atención en el Hospital Amaral Carvalho (Jaú-SP, Brasil) entre noviembre de 2010 y octubre de 2011. Se realizó una encuesta para recoger información con el fin de caracterización demográfica y clínica. Para identificar el estado nutricional se aplico la Valoración Subjetiva Global - Generada por el Paciente Score (VSGGP score). La razón de prevalencia (RP) fue estimada. El nivel de significancia adoptado fue de 5%. Resultados: La edad media de los pacientes fue de 57,45 (DE = 9,62) AÑOs, con los estadíos III y IV de la enfermedad es la más frecuente (39,2% y 35,0%). Había 44,8% de prevalencia de la malnutrición. La persona desnutrida tenía problemas más frecuentes para comer. La estadística descriptiva y la prueba de Chi-cuadrado (< 0,001), presentaron menor deseo de comer (p < 0,001), más náuseas (p = 0,001), vómitos (p = 0,006), estreñimiento (p < 0,001) y dolor (p < 0,001) que los pacientes eutróficos y se declararon enfermos por el olor de los alimentos (p = 0,012), dificultad para tragar (p = 0,002) y la saciedad precoz (p = 0,020) com más frecuencia. En cuanto a la proporción de prevalencia, se observó una probabilidad mayor de individuos desnutridos expuestos a una porción más grande de los síntomas relacionados en la puntuación VSG-GP score. Conclusión: La alta prevalencia de desnutrición se observó en pacientes con cáncer gastrointestinal, con asociación significativa con los síntomas clínicos directamente relacionados con el proceso de alimentación.

    A rapid, sensitive and specific method to quantify nevirapine in human plasma using dibenzepine as the internal standard (IS) was developed and validated. The method employed a liquid-liquid extraction. The analyte and the IS were chromatographed on a C(18) analytical column, (150 x 4.6 mm i.d. 4 microm) and analyzed by tandem mass spectrometry in the multiple reaction monitoring mode. The method had a chromatographic run time of 5.0 min and a linear calibration curve over the range 10-5000 ng ml(-1) (r(2) > 0.9970). The between-run precision, based on the relative standard deviation for replicate quality controls was 1.3% (30 ng ml(-1)), 2.8% (300 ng ml(-1)) and 3.6% (3000 ng ml(-1)). The between-run accuracy was 4.0, 7.0 and 6.2% for the above-mentioned concentrations, respectively. This method was employed in a bioequivalence study of two nevirapine tablet formulations (Nevirapina from Far-Manguinhos, Brazil, as a test formulation, and Viramune from Boehringer Ingelheim do Brasil Química e Farmacêutica, as a reference formulation) in 25 healthy volunteers of both sexes who received a single 200 mg dose of each formulation. The study was conducted using an open, randomized, two-period crossover design with a 3 week washout interval. The 90% confidence interval (CI) of the individual ratio geometric mean for Nevirapina/Viramune was 96.4-104.5% for AUC((0-last)), 91.4-105.1% for AUC((0-infinity)) and 95.3-111.6% for C(max) (AUC = area under the curve; C(max) = peak plasma concentration). Since both 90% CI for AUC((0-last)) and AUC((0-infinity)) and C(max) were included in the 80-125% interval proposed by the US Food and Drug Administration, Nevirapina was considered bioequivalent to Viramune according to both the rate and extent of absorption.

    Introducción: La cantidad de masa ósea adquirida en las primeras etapas de la vida es un importante factor determinante de su pico y el riesgo futuro de osteoporosis y fracturas. Objetivo: Describir la prevalencia de factores que contribuye a la formación de la masa ósea en niños de una cohorte del sur de Brasil. Métodos: Estudio de cohorte retrospectiva con el hospital de todos los nacimientos (2741) se produjo en septiembre / 2002 a mayo / 2003 y el seguimiento de una muestra aleatoria de un 30,0% de los mismos (uno, tres y seis meses y ocho años de edad). En una visita a los ocho años de edad, aplicó un cuestionario con preguntas relacionadas con la alimentación y la actividad física. Resultados y Discusión: De los 616 niños, el 51,3% eran hombres, el 70,3% de raza caucásica, cerca de la mitad pertenecían a la clase económica C, 20,5% tenían sobrepeso, el 16,9% eran obesos y 71,2% sedentarios. La ingesta de alimentos es bajo consumo de frutas, verduras, productos lácteos, carne, los cereales y los tubérculos. La administración de vitamina D en los primeros seis meses de vida fue seguido por 14,1% de los prematuros, el 16,1% de los recién nacidos con bajo peso al nacer, el 24,2% de destete en el primer mes y sólo el 16,4% a los tres meses. Conclusión: Los niños evaluados tienen un bajo consumo de nutrientes, entre ellos el calcio, deficiente administración de vitamina D en el primer semestre de vida, poco actividad física regular y la alta prevalencia del sobrepeso y la obesidad son factores que pueden afectar a la formación de masa ósea.

    Introducción: el envejecimiento de la población ha ido acompañado de cambios epidemiológicos de la población brasileña, destacando el crecimiento continuo de la prevalencia de enfermedades crónicas no transmisibles, especialmente cardiovasculares o de la arteria coronaria, como resultado de los cambios en el perfil lipídico de las personas mayores. Objetivo: describir las variables antropométricas, estilo de vida y composición corporal como factores de comportamiento y su asociación con los cambios en el perfil lipídico de las personas de edad avanzada. Metodología: la muestra incluyó a 402 participantes que asistieron a la Estrategia Salud de la Familia, Viçosa (MG), a los que se aplicó un cuestionario con información socio-demográfica, de comportamiento y de estilo de vida. Se recogió una muestra de sangre para obtener las fracciones de lípidos, y se midió el porcentaje de peso, talla, circunferencia de la cintura y grasa corporal. La regresión lineal múltiple se realizó para identificar factores independientemente asociados con los cambios en cada una de las fracciones de lípidos seleccionados. Resultado: los factores asociados de forma independiente con un aumento de los niveles de colesterol total fueron la presencia de conducta sedentaria, un porcentaje de grasa corporal alto, mayor altura de la cintura y una mayor circunferencia de la cintura. El consumo de bebidas alcohólicas y una proporción cintura-cadera más alta se mantuvo asociado de forma independiente con la disminución de los niveles de lipoproteínas de alta densidad. El aumento de la circunferencia de la cintura se asoció de forma independiente con valores bajos de los niveles de lipoproteínas de baja densidad. El valor del aumento de triglicéridos se asocia de forma independiente con una mayor relación cintura-cadera, un mayor índice de masa corporal y tabaquismo. Conclusión: los factores de riesgo modificables asociados con un perfil lipídico cambiado deben

    Introducción: Brasil es el segundo país del mundo con el mayor número de gimnasios y actualmente representa aproximadamente 30 mil unidades. Cada vez hay más evidencias de que una parte significativa de los practicantes de actividad física desarrollan un compromiso exagerado con esta actividad, que incluso pueden generar dependencia patológica. Objetivo: determinar la asociación entre la práctica exagerada de ejercicio físico (ED) y el consumo de suplementos entre los practicantes. Método: se utilizó la escala de adicción al ejercicio en practicantes mayores de 19 años, de ambos sexos. Fue realizada una entrevista individual para determinar históricamente el consumo de suplementos; también se evaluaron los resultados de antropometría y la frecuencia departicipación en el gimnasio. Resultados: la frecuencia de la práctica en el gimnasio fue del 66,5% y la prevalencia de la suplementación fue de 51,5%, la posibilidades de un adicto al ejercicio ser un consumidor de suplemento se estima en 4,53. Conclusión: la relación entre la adicción al ejercicio y el consumo de suplemento fue comprobada, constituyendo una alerta para los profesionales de la salud, que deben tener en cuenta los factores de riesgo para el desarrollo de los signos más graves y síntomas, incluyendo el control de peso obsesivo por medio de la práctica intensa de ejercicios físicos, consumo de dietas inadecuadas y uso de suplementos nutricionales. Se recomienda que la evaluación nutricional se complemente de otras determinaciones para detectar la adicción al ejercicio y el uso de suplementación nutricional. Si es necesario, se pueden promover campañas para avalar las dietas consumidas, la composición corporal ideal y detectarlos cambios drásticos en la alimentación, así como otras cuestiones relacionadas con el cuidado nutricional en general.

    Introducción: Los efectos de la carga glucémica (CG) de la dieta sobre los factores de riesgo cardiometabólico en sujetos físicamente activos no están establecidos por completo. Objetivo: Este estudio transversal evaluó la asociación entre la CG de la dieta habitual y los factores de riesgo cardiometabólico en hombres brasileños de mediana edad físicamente activos. Métodos: Ciento setenta y seis sujetos (índice de masa corporal: 25,5 ± 3,6 kg/m2; edad: 50,6 ± 5,0 años) fueron evaluados. Antropometría, características del estilo de vida, la resistencia a la insulina, biomarcadores del estrés oxidativo (8-iso-prostaglandina F2, 8-iso-PGF2y 8 hidroxideoxiguanosina, 8-OHdG) y el perfil lipídico fueron evaluados. La ingesta dietética se estimó por medio de un cuestionario cuantitativo de frecuencia de consumo. Resultados: La CG de la dieta se asoció positivamente con las concentraciones de ácidos grasos libres (= 0,311, r2 = 0,13, P = 0,034) y la razón triglicéridos/colesterol HDL (= 0,598, r2 = 0,19, P = 0,028), independientemente de los factores de confusión (obesidad central, consumo de carne roja, edad e ingesta calórica). El biomarcador del estrés oxidativo, 8-OHdG, también se asoció con CG de la dieta habitual (= 0,432, r2 = 0,11, P = 0,004), independientemente de los factores de confusión anteriores más el consumo excesivo de alcohol, la ingesta de hierro y tabaquismo actual. Conclusiones: La CG de la dieta se asoció positivamente con el perfil lipídico (concentraciones de ácidos grasos libres y razón triglicéridos/HDL colesterol) y el biomarcador de estrés oxidativo 8-OHdG. Estos resultados indican el potencial de nocividad de una dieta con mayor CG respecto a los factores de riesgo cardiometabólico en hombres de mediana edad, incluso en aquellos físicamente activos.

    Introducción: Dolor de cabeza se ha descrito como un factor con impacto negativo significativo en la calidad de vida de los niños en edad escolar, con alto riesgo de desarrollar la forma crónica y persistente en la edad adulta. Entre otros factores desencadenantes o agravantes asociados, se ha investigado el estilo de vida y la obesidad, pero los resultados siguen siendo contradictorios. Objetivo: Evaluar la prevalencia de dolor de cabeza en niños en edad escolar y su relación con las características antropométricas, estilo de vida y calidad de vida. Métodos: Un estudio transversal se llevó a cabo en seis escuelas ubicadas en dos ciudades del sur de Brasil, con la participación de 750 estudiantes de 7 a 14 años. Se obtuvo información sobre características sociodemográficas, variables clínicas (presencia de dolor de cabeza y la menarquia), datos antropométricos, estilo de vida y calidad de vida. Resultados: Un total de 185 (24,7%) estudiantes reportaron tener crisis de dolor de cabeza en los últimos 3 meses. Entre los estudiantes de 10 a 14 años, presencia de dolor de cabeza se asoció con el sexo femenino, que afecta a un 32,2% de niñas frente a un 23,3% de los varones (p = 0,042, chi-cuadrado). Parámetros antropométricos (datos de sobrepeso/ obesidad) fueron consistentes con las tasas nacionales de prevalencia, y no hubo asociación entre el Índice de Masa Corporal (IMC) y dolor de cabeza. En cuanto a estilo de vida, 2,0% de los estudiantes reportaron fumar y un 1,6% el consumo de alcohol de vez en cuando, y no se asoció con dolor de cabeza. La calidad de vida, especialmente los aspectos de la vida social, parece estar afectada por la presencia de dolor de cabeza. Conclusión: Este estudio encontró una alta prevalencia de dolor de cabeza en niños en edad escolar, que se asoció con estudiantes de 10-14 años y la calidad de vida.

    Introducción: la funcion tiroidea depende de minerales traza de selenio (Se), que esta en el centro activo de la deiodinasa yodotironina, que cataliza la conversion de la tiroxina (T4) a la forma activa de la hormona tiroidea, triyodotironina (T3). Hemodialisis (HD) de los pacientes ha reducido los niveles de T3 de los pacientes, debido en parte a la conversion hormonal alterada que puede estar relacionada con la deficiencia de Se, una caracteristica comun en estos pacientes. Este estudio evaluo el efecto de las nueces de Brasil (la mas rica fuente de Se) en los niveles de hormonas tiroideas en pacientes en HD. Métodos: se realizo una intervencion no controlada con 40 pacientes en HD (53,3 } 16,1 anos, dialisis vendimia 62,0 (8,0 - 207,0 meses)), que recibieron una nuez (≈ 5, promedio 58,1 mg Se/g) por dia durante tres meses. Determinaron los niveles plasmaticos de Se por espectrofotometria de absorcion atomica con generacion de hidruros y los niveles de T3, T4 libre (FT4), TSH en suero, asi como la actividad de la glutation peroxidasa (GPx) por ELISA. Resultados: todos los pacientes tenian niveles bajos de Se y T3 al inicio del estudio. Despues de la intervencion, los niveles plasmaticos de Se (de 17,6 } 11,6 a 153,4 } 86,1 mg/L), actividad GPx (de 33,7 } 5,9 a 41,4 } 11,2 nmol/min/ml), T3 (de 27,3 } 8,8 a 50,2 } 4,8 ng/dL) y T4L (0,87 } 0,2 a 0,98 } 0,4 ng/dL) se incrementaron significativamente (p < 0,05), mientras que los niveles de TSH se redujeron (de 2,17 } 1,3 a 1,96 } 1,1 IUU/ml), pero no de forma significativa. Conclusión: en conclusion, el aumento de los niveles de Se via suplementacion con nuez brasilena se asocia con una mejoria en los niveles de hormonas tiroideas en pacientes en HD, aunque la cantidad de Se dada no fue capaz de restablecer la T3 a los niveles normales.

    Antecedentes: El síndrome metabólico (SM) se sugiere que está asociada con un estado de inflamación crónica de bajo grado, pero la relación entre biomarcadores de inflamación crónica de bajo grado, pero la relación entre biomarcadores de inflamación y los componentes del síndrome metabólico en adolescentes son escasos. Objetivo: Investigar la asociación entre las concentraciones séricas de proteína C reactiva (CRP) y los componentes del síndrome metabólico en adolescentes. Metodología: Hemos realizado una población basada en estudio de corte transversal. Los datos antropométricos, bioquímicos y clínicos se obtuvieron de 524 adolescentes (11-15 años de edad) seleccionados al azar de la población escolar de la ciudad Alegre, Espírito Santo, Brasil. Los datos fueron analizados por STATA versión 9.0. Resultados: Los adolescentes, con valores más altos de IMC (p = 0,001) y mayor porcentaje de grasa corporal (p = 0,003) tuvieron mayores concentraciones de PCR que aquellos con menor IMC y porcentaje de grasa corporal. Las concentraciones de PCR se correlacionó directamente con el IMC (r = 0,17, p = 0,0001), la circunferencia de la cintura (r = 0,15, p = 0,0005), HDL-c (r = 0,13, p = 0,003), la insulina en ayunas (r = 0,12, p = 0,009) y la presión arterial sistólica (r = 0,11, p = a 0,01). En el análisis de regresión lineal múltiple IMC (r = 0,05, p = 0,002), la glucosa en ayunas (r = -0,01, p = 0,003) y HDL-c (r = 0,017, p < 0,001) se asociaron a las concentraciones de PCR después de ajustar por los otros componentes de SM. Conclusión: La asociación encontrada entre los componentes individuales de SM y las concentraciones de PCR sugiere que la inflamación podría ser un evento temprano en el desarrollo de trastornos metabólicos en los adolescentes.

    A report and an updated list with comments on the species of freshwater molluscs of Argentina which covers an area of 2 777 815 km2 is presented. Distributions of Gastropoda and Bivalvia families, endemic, exotic, invasive as well as entities of sanitary importance are also studied and recommendations on their conservation are provided. Molluscs related to the Del Plata Basin have been thoroughly studied in comparison to others areas of the country. This fauna exhibits relatively the biggest specific richness and keeps its affinity with the fauna of other regions of the basin in areas of Paraguay and Brasil. The 4 500 records of molluscs considered in this paper arise from the study of the collections of Museo Argentino de Ciencias Naturales "Bernardino Rivadavia", Buenos Aires; Museo de La Plata, La Plata and Fundación "Miguel Lillo", Tucumán. These institutions keep very important collections of molluscs in southern South America. Field information has recently been obtained and localities cited by other authors are also included in the data base. Until today, 166 species have been described, 101 belonging to 10 families of Gastropoda and 65 to 7 of Bivalvia. Families with highest specific richness are Lithoglyphidae (22) and Sphaeriidae (25), respectively. The number of endemic species (those present only in Argentina) by family is: Gastropoda: Ampullariidae (1), Cochliopidae (10), Lithoglyphidae (11), Thiariidae (3), Chilinidae (11), Lymnaeidae (2) and Physidae (2?); Bivalvia: Hyriidae (1?); Etheriidae (1?) and Sphaeriidae (10). Families with a distribution that comprise almost the whole country are: the Sphaeriidae and the gastropods Cochliopidae, Chilinidae and Lymnaeidae. Families Erodonidae and Solecurtidae (Bivalvia) were registered in mixohaline environments from Buenos Aires province. Gastropod families Thiaridae and Glacidorbiidae show a very restricted distribution. The rest of the families are present mainly in the center and north of the country

    Introducción: La estatura es una variable importante en varios índices del estado nutricional que son aplicables a las personas mayores. Sin embargo, la estatura es difícil o imposible de medir en la edad avanzada, ya que a menudo son incapaces de mantener la posición de pie. Una alternativa es el uso de altura estimada a partir de mediciones de medida de altura de la rodilla. Objetivos: Este estudio tuvo como objetivo evaluar la exactitud de la fórmula propuesta por Chumlea et al. (1985), basado en la altura de la rodilla de una población caucásica para estimar la altura y su aplicación en el cálculo del índice de masa corporal en las personas mayores residentes en la comunidad de Viçosa, Minas Gerais, Brasil. Métodos: La muestra incluyó a 621 adultos mayores de 60 anõs y más, que viven en la comunidad. Se tomaron medidas de peso, talla y altura de la rodilla (AR) y el Índice de Masa Corporal (IMC) se calculó con el peso medido y estimado. Se utilize la prueba T del estudiante para la comparación de las mediciones de altura entre los géneros. Para la comparación de los valores estimados y medidos se utilizó la prueba T pareada y también la metodología propuesta por Bland y Altman para comparar la diferencia entre las mediciones. Para evaluar el acuerdo entre las clasificaciones para el IMC se utilizó el Kappa de Cohen. Resultados: Los valores medios obtenidos a partir de AR fueron más altos que los medidos en la muestra completa y mujeres. Hay subestimación de IMC en mujeres y también en el conjunto. Conclusiones: Los resultados sugieren que la ecuación Chumlea no era adecuado para estimar la altura de la muestra en cuestión, especialmente para las mujeres.

    The aim of this study was to compare the development of eucalyptus in a degraded Oxisol with mineral fertilizer and sewage sludge. The study was conducted in Selviria, Mato Grosso do Sul, Brasil. The culture of eucalyptus was planted in 2003 at 2.0 m x 1.5 m spacing, with application of 60 Mg ha-1 of sewage sludge (dry basis) and mineral fertilizer. After five years (2008) the area received biosolids and mineral fertilizer, and after five months, were evaluated for height and diameter at breast height of Eucalyptus. The experimental design was randomized blocks with four treatments: T1 - control (without addition of inputs), T2 - Mineral fertilization (30 kg ha-1 N, 90 kg ha-1 of P2O5 and 60 kg ha-1 K2O), T3 - Reapplication of 4.64 Mg ha-1 of sewage sludge, dry basis, T4 - Reapplication of 9.28 Mg ha-1 of sewage sludge, dry basis. Before reapplication the biosolids plant height was higher in the eucalyptus with treatment 9.28 Mg ha-1 of sewage sludge (8.03 m) compared to control (5.75 m) and mineral fertilizer (5.91 m) and that treatment 4.64 Mg ha-1 of sewage sludge (6.34 m) did not differ from the previous three. For the diameter at breast height was the highest value for treatment with 9.28 Mg ha-1 (7.78 cm) compared to control (5.23 cm) and 4.64 Mg ha-1 (5.03 cm), and that of mineral fertilizer (5.96 cm) did not differ from all treatments. After reapplication of sludge plant height was higher in the eucalyptus treatment with 9.28 Mg ha-1 of sewage sludge (11.21 m) compared with control (7.51 m), mineral fertilizer (7.77 m) and 4 64 Mg ha-1 (8.07 m), which did not differ. The diameter at breast height had the same behavior before the application of biosolids in the highest value observed being 9.28 Mg ha-1 (8.46 cm) compared with control (5.75 cm) and 4.64 Mg ha-1 (5.03 cm) and that of mineral fertilizer (6.34 cm) did not differ from the others. Reapplication of the dose of 9.28 Mg ha-1 of sewage sludge in degraded Oxisol provided greater height and diameter at

    Planctomyces brasiliensis Schlesner 1990 belongs to the order Planctomycetales, which differs from other bacterial taxa by several distinctive features such as internal cell compartmentalization, multiplication by forming buds directly from the spherical, ovoid or pear-shaped mother cell and a cell wall consisting of a proteinaceous layer rather than a peptidoglycan layer. The first strains of P. brasiliensis, including the type strain IFAM 1448 T, were isolated from a water sample of Lagoa Vermelha, a salt pit near Rio de Janeiro, Brasil. This is the second completed genome sequence of a type strain of the genus Planctomyces to be published and the sixth type strain genome sequence from the family Planctomycetaceae. The 6,006,602 bp long genome with its 4,811 protein-coding and 54 RNA genes is a part of the Genomic Encyclopedia of Bacteria and Archaea project. We study phylogenomic analyses that indicate that the classification within the Planctomycetaceae is partially in conflict with its evolutionary history, as the positioning of Schlesneria renders the genus Planctomyces paraphyletic. A re-analysis of published fatty-acid measurements also does not support the current arrangement of the two genera. A quantitative comparison of phylogenetic and phenotypic aspects indicates that the three Planctomyces species with type strains available in public culture collections should be placed in separate genera. Thus the genera Gimesia, Planctopirus and Rubinisphaera are proposed to accommodate P. maris, P. limnophilus and P. brasiliensis, respectively. Pronounced differences between the reported G + C content of Gemmata obscuriglobus, Singulisphaera acidiphila and Zavarzinella formosa and G + C content calculated from their genome sequences call for emendation of their species descriptions. Lastly, in addition to other features, the range of G + C values reported for

    We present an analysis of 42 years of continuous measurements of the photospheric solar diameter, taken at major national observatories, using the same fundamental method, and similar apparatus. Such a series overlap observations from the Calern Observatory/France (Solar Astrolabe in 1975-2003 to 253 obs/year lead by F. Laclare and C. Delmas; Doraysol in 2000-2005 to 3,070 obs/year lead by C. Delmas and V. Sinceac), from the IAG/USP/Brazil (Solar Astrolabe in 1974-1994 to 95 obs/year lead by N. VaniLeister, P. Benevides and M. Emilio), from the Antalya Observatory/Turkey (CCD Astrolabe in 2000-2007 to 400 obs/year lead by F. Chollet and OI. Golbasi), from the San Fernando Observatory/Spain (Solar Astrolabe in 1972-1975 to 133 obs/year lead by J. Muiños), from Observatório Nacional/Brasil (CCD Astrolabe in 1998-2009 to 1,820 obs/year lead by J. Penna, E. Reis Neto and A.H. Andrei; Heliometer 2010-2015 to 8,509 obs/year lead by S.C. Boscardin, J.L. Penna and A.H. Andrei). The Heliometer is fully automatized in its observations and continues in regular operation with no plan of stopping; it shares with the former instruments the physical/mathematical definition of the limb, and the instruments aperture and focal length. We perform a reconciliation of all these series, using the common stretches. A modulation with the 11 years cycle of solar activity is evident. However when such modulation is removed, both from the solar diameter compound series and from the solar activity series (given by the sunspots count), a very strong anti-correlation surfaces. This suggests a smaller diameter for the forthcoming cycles, in a behavior similar to that on the Minima of Dalton and Maunder. This study stresses the importance of keeping and make available such long, continuous, and uniform series of solar diameter measurements. Maybe even the more by the controversy about its magnitude and origin. This presentation is dedicated to all the teams that developed and sustained the

    Background Primary Sjögren’s Syndrome (pSS) is a systemic autoimmune disease that involves the exocrine glands and internal organs. pSS leads to destruction and loss of secretory function due to intense lymphoplasmacytic infiltration. Therapeutic options include mainly symptomatic and supportive measures, and traditional immunosuppressant drugs have shown no effectiveness in randomized trials. Rituximab (RTX) is a chimeric antibody anti-CD20 that leads to B cell depletion by diverse mechanisms. There is evidence that this drug may be effective for treating pSS. The objective of this systematic review was to evaluate Rituximab effectiveness and safety for treating pSS. Methods and Findings We conducted a systematic review of RCTs published until December 2015, with no language restriction. We registered a protocol on Plataforma Brasil (40654814.6.0000.5505) and developed search strategies for the following scientific databases: MEDLINE, EMBASE, CENTRAL and LILACS. We included adults with established pSS diagnosis and considered the use of Rituximab as intervention and the use of other drugs or placebo as control. Four studies met our eligibility criteria: three with low risk of bias and one with uncertain risk of bias. The total number of participants was 276 (145 RTX, 131 placebo). We assessed the risk of bias of each included study and evaluated the following as primary outcomes: lacrimal gland function, salivary gland function, fatigue improvement and adverse events. We found no significant differences between the groups in the Schirmer test at week 24 meta-analysis (MD 3.59, 95% CI -2.89 to 10.07). Only one study evaluated the lissamine green test and reported a statistically significant difference between the groups at week 24 (MD -2.00, 95% CI -3.52 to -0.48). There was a significant difference between the groups regarding salivary flow rate (MD 0.09, 95% CI 0.02 to 0.16) and improvement in fatigue VAS at weeks 6 (RR 3.98, 95% CI 1.61 to 9.82) and week 16

    Introducción: La contribución de la dieta y planificación del tratamiento en el tratamiento de la enfermedad renal crónica (ERC) ha sido reconocida por tener un impacto clínico significativo si introducida tempranamente. Objetivo: determinar los niveles de hidratos de carbono, proteínas, lípidos, energía y densidad de energía (DE) en una dieta hospitalaria oral recetada para los pacientes con ERC, y evaluar la adecuación de esta dieta con respecto a las recomendaciones dietéticas. Métodos: Las dietas fueron recogidas en un hospital público brasileño en dos días no consecutivos de seis semanas diferentes. Los contenidos de los hidratos de carbono, proteínas, y lípidos (totales, saturadas, monoinsaturadas, poliinsaturadas, ácidos grasos linoleico, linolénico y trans) fueran determinados en un laboratorio. La cantidad de energía y la DE de las dietas se calcularon utilizando el factor de corrección de Atware, dividiendo la energía total de la dieta en peso, respectivamente. Resultados y Discusión: Fueran analizadas cerca de 14.3% de las dietas producidas y servidas a los pacientes con ERC. La densidad media de las di etas fue baja (0,7 kcal/g). Fue encontrada inadecuación nutricional para el contenido medio en lípidos (15%) y contenido de ácido graso linolénico (0,4%) y de energía (23,4 kcal/kg/día). El contenido de carbohidratos (63,5%) y el contenido de proteínas (1,0 g/kg/día) superaron los niveles de recomendaciones. Conclusiones: La dieta hospitalaria oral preparada para los pacientes con enfermedad renal crónica se muestra desequilibrada y desfavorable para el tratamiento clínico de los pacientes.

    Introducción: el síndrome metabólico es un grupo de enfermedades que ha ido ganando importancia debido a la asociación con el desarrollo posterior de enfermedades cardiovasculares. Objetivo: verificar la prevalencia de factores de riesgo asociados con el síndrome metabólico en niños de una cohorte del sur de Brasil. Métodos: estudio de cohorte prospectivo con el hospital de todos los nacimientos (2.741) que tuvieron lugar en el mes de septiembre/2002 a mayo/2003 y seguimiento de una muestra aleatoria de 30,0% con uno, tres y seis meses y ocho años de edad. En una visita a los ocho años de edad se utilizó un cuestionario con preguntas relacionadas con la nutrición, la actividad física y la historia familiar de enfermedades crónicas, y se midieron peso, talla y circunferencia de la cintura. Se realizaron análisis descriptivos y bivariados entre las variables independientes y los resultados obtenidos. Resultados y discusión: de 616 niños estudiados, el 51,3% fueron varones, el 70,3% blancos, cerca de la mitad pertenecían a la clase económica C, el 20,6% tenían sobrepeso y el 17,0% eran obesos. Mostró una alta prevalencia de historia familiar de hipertensión arterial (81,5%), y se observó que el 20,7% de los niños eutróficos tenían una circunferencia de cintura elevada. Conclusión: la alta prevalencia de factores de riesgo para el síndrome metabólico en los niños estudiados refuerza la importancia de una adecuada anamnesis: historia familiar. Se sugiere medir la circunferencia de la cintura en la rutina de cuidados pediátricos.

    Objetivo: Comparar el control glucémico y el perfil lipídico de niños y adolescentes sometidos a dos tratamientos dietéticos distintos para la diabetes mellitus tipo 1 atendidos en el Centro de Salud para Niños y Adolescentes con Diabetes Mellitus-UFRJ. Métodos: Estudio longitudinal retrospectivo realizado entre 2002 y 2006. Evaluamos a los mismos individuos en dos momentos distintos: tras un año en tratamiento para diabetes (TD) y posteriormente tras un año con conteo de hidratos de carbono (CHC). La evolución del estado nutricional durante los tratamientos dietéticos se evaluó empleando el índice de masa corporal (IMC) para la edad. El panel de lípidos se evaluó de acuerdo con la 1ª Guía para la prevención de la aterosclerosis en la infancia y adolescencia, empleada en Brasil, y el control glucémico se evaluó midiendo la hemoglobina glucosilada (HbA1c). Resultados: Evaluamos a 93 individuos, 38,7 % niños y 61,3 % adolescentes. La edad promedio en el momento de entrada en el estudio fue de 11,1 (± 2,66) años y la el promedio de duración de la enfermedad fue de 6,1 (± 3,2) años. Se encontró una diferencia significativa en el porcentaje de adecuación de la HbA1c (p = 0,000) y en los valores del colesterol plasmático total (p = 0,043) tras un año de dieta con CHC, lo cual no ocurrió durante el periodo de observación de TD. La evolución del estado nutricional antropométrico no mostró diferencias significativas entre el inicio y el final de ninguno de los tratamientos dietéticos. Conclusión: Los resultados de este estudio sugieren que un programa de orientación alimentaria más flexible puede contribuir a la mejora de la glucemia sin producir un deterioro del perfil lipídico en comparación con el TD.

    Introducción: La práctica regular de actividad física (AF) se ha asociado con una mejor salud. Además, las características del trabajo se pueden determinar las conductas de la AF de los trabajadores, incluyendo el turno de trabajo. Sin embargo, relativamente pocos estudios han examinado el comportamiento AF entre los trabajadores por turnos. Objetivo: Este estudio tuvo como objetivo investigar la asociación entre turno de trabajo y la práctica de la AF entre los trabajadores de una planta de procesamiento de aves en el sur de Brasil. Métodos: Un estudio transversal se llevó a cabo con 1.206 trabajadores (786 mujeres), con edades entre 18 a 50 años, trabajando en turnos de una línea de producción que funciona las 24 horas/día. Los trabajadores que han participado en más de 150 minutos/semana de AF se consideraron activos. Se realizó un análisis multivariante mediante regresión de Poisson y todos los análisis se estratificó por sexo. Resultados: De los participantes en el estudio, el 36% (IC del 95%: 33-39) se consideraron activas y las características sociodemográficas asociadas con AF difirieron entre machos y hembras. En cuanto a los turnos de trabajo, los trabajadores del turno de noche tenían mayor prevalencia de la AF. Sin embargo, el aumento de la AF se asoció significativamente con el trabajo por turnos sobre todo entre las mujeres. Después de ajustar por factores de confusión, las mujeres que trabajaban en el turno de la noche fueron aproximadamente un 30% más activos que los que han trabajado durante el día (PR[razón de prevalencia]=1,32;IC del 95%: 1,07-1,62;p=0,010). Conclusiones: Este estudio encontró una baja prevalencia de PA entre los trabajadores e indicó una asociación significativa entre el trabajo por turnos y AF. Trabajar de noche se asoció positivamente con la AF regular, especialmente entre las mujeres. Estos resultados contribuyen a las iniciativas para aumentar la AF entre los trabajadores, teniendo en cuenta

    Carbonate sediments are prone to rapid and pervasive diagenetic alterations that change the mineralogy and pore structure within carbonate units. In particular, cementation and dissolution processes continuously modify the pore structure to create or destroy porosity. In extreme cases these modifications can completely change the mineralogy from calcite to dolomite, in the properties of rock for soil (Caliche), or reverse the pore distribution whereby original grains are dissolved to produce pores as the original pore space is filled with cement to form the rock. These processes are common in fractured carbonate units. All these modifications alter the elastic properties of the rock and, therefore, the sonic velocity. This study presents the result of relationship among diagenesis, porosity, grain density, and sonic velocity, in limestones, dolomites and caliche samples from the Jandaíra Formation, Potiguar basin, Brasil. This stratigraphic unit have been subjected to fracturing since the late Cretaceous. The rock and soil samples were collected in outcrops, prepared as plugs, and analyzed at ambient temperature. The porosity and grain density analysis were performed under ambient pressure, while elastic properties analyses were conducted with samples under confining pressure between 5 and 40 MPa. The result is a wide range of sonic velocity in carbonates, in which compressional-wave velocity (VP) ranges from 3507 to 6119 m/s and shear-wave velocity (VS) range from 2114 to 3451 m/s. The ratio VS1/VS2 indicate a level of anisotropy equal to 2%, without any clear relationship with porosity. The elastics properties are affected by rock alteration process or by modification of mineral composition, due to the presence of clay minerals and organic matter, The porosity and grain density values range from 3.2 to 21.5%, and 2.7 to 2.8 (g/cm3), respectively. The grain density analysis in the carbonate rocks indicate the existence of two groups: the first group of calcareous

    Environmental modification by anthropogenic actions, disordered urban growth, globalization of international exchange and climate change are some factors that help the emergence and dissemination of human infectious diseases transmitted by vectors. This review discusses the recent entry of three arboviruses in Brazil: Chikungunya, West Nile, and Zika virus, focusing on the challenges for the Country's public health. The Brazilian population is exposed to infections caused by these three arboviruses widely distributed on the national territory and associated with humans. Without effective vaccine and specific treatment, the maintainance and integration of a continuos entomological and epidemiological surveillance are important so we can set methods to control and prevent these arboviruses in the Country. RESUMO A modificação do ambiente por ações antrópicas, o crescimento urbano desordenado, o processo de globalização do intercâmbio internacional e as mudanças climáticas são alguns fatores que vêm facilitando a emergência e disseminação de doenças infecciosas humanas transmitidas por vetores. Este comentário aborda a recente entrada de três arbovírus no Brasil, Chikungunya (CHIKV), West Nile (WNV) e Zika (ZIKV), com enfoque nos desafios para a Saúde Pública do País. Transmitidos por mosquitos vetores amplamente distribuídos no território nacional e associados ao homem, a população brasileira encontra-se exposta à infecção por esses três arbovírus. Na ausência de vacina eficaz e tratamento específico, são importantes a manutenção e integração de uma vigilância entomológica e epidemiológica contínua, a fim de direcionarmos métodos de controle e prevenção contra essas arboviroses no País.

    We report a study of the stellar content of the near-infrared (NIR) cluster [DBS2003] 157 embedded in the extended H II region GAL 331.31-00.34, which is associated with the IRAS source 16085-5138. JHK photometry was carried out in order to identify potential ionizing candidates, and the follow-up NIR spectroscopy allowed the spectral classification of some sources, including two O-type stars. A combination of NIR photometry and spectroscopy data was used to obtain the distance of these two stars, with the method of spectroscopic parallax: IRS 298 (O6 V, 3.35 ± 0.61 kpc) and IRS 339 (O9 V, 3.24 ± 0.56 kpc). Adopting the average distance of 3.29 ± 0.58 kpc and comparing the Lyman continuum luminosity of these stars with that required to account for the radio continuum flux of the H II region, we conclude that these two stars are the ionizing sources of GAL 331.31-00.34. Young stellar objects (YSOs) were searched by using our NIR photometry and mid-infrared (MIR) data from the Galactic Legacy Infrared Mid-Plane Survey Extraordinaire (GLIMPSE) survey. The analysis of NIR and MIR colour-colour diagrams resulted in 47 YSO candidates. The GLIMPSE counterpart of IRAS 16085-5138, which presents IRAS colour indices compatible with an ultracompact H II region, has been identified. The analysis of its spectral energy distribution between 2 and ?m revealed that this source shows a spectral index α= 3.6 between 2 and ?m, which is typical of a YSO immersed in a protostellar envelope. Lower limits to the bolometric luminosity and the mass of the embedded protostar have been estimated as L= 7.7 × 103 L⊙ and M= 10 M⊙, respectively, which correspond to a B0-B1 V zero-age main sequence star.

    We present near-infrared spectroscopy for 52 ultracool dwarfs, including two newly discovered late-M dwarfs, one new late-M subdwarf candidate, three new L, and four new T dwarfs. We also present parallaxes and proper motions for 21 of them. Four of the targets presented here have previous parallax measurements, while all the others are new values. This allow us to populate further the spectral sequence at early types (L0-L4). Combining the astrometric parameters with the new near-infrared spectroscopy presented here, we are able to investigate further the nature of some of the objects. In particular, we find that the peculiar blue L1 dwarf SDSS J133148.92-011651.4 is a metal-poor object, likely a member of the galactic thick disk. We discover a new M subdwarf candidate, 2MASS J20115649-6201127. We confirm the low-gravity nature of EROS-MP J0032-4405, DENIS-P J035726.9-441730, and 2MASS J22134491-2136079. We present two new metal-poor dwarfs: the L4pec 2MASS J19285196-4356256 and the M7pec SIPS2346-5928. We also determine the effective temperature and bolometric luminosity of the 21 targets with astrometric measurements, and we obtain a new polynomial relation between effective temperature and near-infrared spectral type. The new fit suggests a flattening of the sequence at the transition between M and L spectral types. This could be an effect of dust formation, which causes a more rapid evolution of the spectral features as a function of the effective temperature.

Total sediments (TS) of the sliced profiles (62 cm, Botafogo river and 87 cm, Manguaba river ) were submitted to chemical analysis (51 elements), mineralogical analysis (XRD) and statistical study, followed by stoichiometric calculations. Geochronologic determinations of 210Pb allowed studying the evolution of the contamination level approximately 150 year-old interval in the Botafogo river. Mercury (Hg) and Arsenic (As) are emphasized because of a chlorine-soda industry that dumps its effluents about 15 km upstream of the estuary and extensive cultivation of sugarcane existent in this watershed. Hg background in pelitic total sediments (PTS) was certain established considering the Hg content (126 ppb) in sedimentary intervals previous to 1910. The production of chlorine-soda (since 1963) coincides with a drastic increase of the Hg concentrations and contemporary values around 6.000 ppb, without interruption in the pollutant process. The conclusions found that the Hg was the main indicator of anthropogenic contribution in the sediments of the Botafogo river. On the other hand, an increase in the Hg-As concentrations has been observed at the last decades due to an increase of the clay mineral fraction in TS of the Manguaga river. This scenario indicates that the accumulation of HM has been constant since the last decades, under a

    Introdução: A ocorrência recente de um conjunto de surtos de dengue em países da lusofonia previamente livres de doença, despertou- nos curiosidade quanto aos fatores concorrentes para o fenómeno e a necessidade de aprofundar conhecimentos quanto à patologia. Revemos a situação relativa à dengue nos países da lusofonia, relacionando os diferentes surtos e procurando contribuir para um melhor conhecimento do fenómeno. Material e Métodos: Revisão da literatura relativa ao tema e informação relevante obtida de comunicações orais. Resultados: Os surtos ocorridos entre os anos de 2009 e 2013 em Cabo Verde, Madeira e Angola (para lá da doença endémica no Brasil) partilham o mesmo vetor Aedes aegypti, mas são devidos a serotipos víricos com diferentes proveniências, como constatado em estudos genotípicos. A forte sub-notificação da doença em África e as dificuldades no diagnóstico e terapêutica são obstáculos ao real conhecimento da situação. Discussão: A hipótese de ligação entre alguns dos surtos não está completamente afastada. Pela elevada mobilidade de pessoas entre estas zonas e pelas alterações climáticas em curso, o território de Portugal expõe-se ao risco de introdução de dengue. A luta principal, a despeito de ferramentas emergentes ainda utópicas, é sem dúvida o controlo vetorial. Conclusão: Não foi possível provar qualquer ligação entre os diferentes surtos, mas é necessária preparação local dos profissionais de saúde, bem como o estabelecimento de estratégias de saúde pública e manutenção de redes de vigilância. Mais estudos epidemiológicos e entomológicos são necessários para caracterizar a verdadeira incidência de doença nos países lusófonos.

  13. Water-related absorption in fibrous diamonds

    Cubic and coated diamonds from several localities (Brasil, Canada, Yakutia) were investigated using spectroscopic techniques. Special emphasis was put on investigation of water-related features of transmission Infra-red and Raman spectra. Presence of molecular water is inferred from broad absorption bands in IR at 3420 and 1640 cm-1. These bands were observed in many of the investigated samples. It is likely that molecular water is present in microinclusions in liquid state, since no clear indications of solid H_2O (ice VI-VII, Kagi et al., 2000) were found. Comparison of absorption by HOH and OH vibrations shows that diamonds can be separated into two principal groups: those containing liquid water (direct proportionality of OH and HOH absorption) and those with stronger absorption by OH group. Fraction of diamonds in every group depends on their provenance. There might be positive correlation between internal pressure in microinclusions (determined using quartz barometer, Navon et al., 1988) and affiliation with diamonds containing liquid water. In many cases absorption by HOH vibration is considerably lower than absorption by hydroxyl (OH) group. This may be explained if OH groups are partially present in mineral and/or melt inclusions. This hypothesis is supported by following fact: in diamonds with strong absorption by silicates and other minerals shape and position of the OH band differs from that in diamonds with low absorption by minerals. Moreover, in Raman spectra of individual inclusions sometimes the broad band at 3100 cm-1 is observed. This band is OH-related. In some samples water distribution is not homogeneous. Central part of the diamond usually contains more water than outer parts, but this is not a general rule for all the samples. Water absorption usually correlated with absorption of other components (carbonates, silicates and others). At that fibrous diamonds with relatively high content of silicates are characterized by molecular water. OH

    Introducción: La retención del aumento de peso durante el embarazo y el aumento de peso después del parto se ha asociado a una mayor prevalencia de la obesidad en las mujeres en edad fértil. Objetivo: Identificar los factores determinantes de la variación del peso en los 24 meses posparto, en mujeres adultas en dos municipios de Bahía/Brasil. Métodos: En una cohorte dinámica se incluyeron 325 mujeres, acompañadas durante 24 meses. La variación del peso a los 24 meses después del parto se consideró variable de respuesta y los factores socioeconómicos, demográficos, reproductivos, de la estilo de vida y factores relacionados con el niño, son las variables de exposición. En el análisis de datos se construyeron modelos de regresión lineal de efectos mixtos con un enfoque jerárquico para identificar los determinantes de la variación del peso posparto. Resultados: Han contribuido al aumento de peso en el nivel distal, inadecuadas condiciones sanitarias de la vivienda (2,175 kg, p = 0,001) y la participación en los programas sociales de transferencia de ingresos (1.300 kg; p = 0,018). En el nivel intermedio, el exceso de peso antes del embarazo aumentó el peso después del parto en una media de 3,380 kg (p < 0,001), mientras que el parto por cesárea contribuyó a la pérdida de 2,451 kg (p < 0,001). A nivel proximal, el aumento de un punto en la puntuación de la lactancia materna contribuyo con la pérdida de 70 g (p = 0,002) en la media del peso posparto. Conclusiones: Estos resultados indican a la necesidad de las acciones de salud dirigidas a controlar el peso durante el embarazo y después del parto incluyendo la promoción de la lactancia materna durante largos períodos y la mejora de las condiciones de vida, que implica acciones intersectoriales.

    Objetivo: Evaluar la ingesta de nutrientes y el estado nutricional de los alimentos en pacientes con cáncer ingresados en un hospital universitario, comparando por categoría de edad entre adulto y adulto mayor. Métodos: Estudio transversal. Este estudio incluía pacientes cancerosos ingresados en un hospital en 2010. Se recogieron los hábitos dietéticos mediante un cuestionario brasileño de frecuencia de alimentos. Se dividieron los participantes en dos grupos: adultos y adultos mayores y en 4 categorías de cáncer: hematológico, pulmonar, gastrointestinal y otros. El estado nutricional se evaluó con el índice de masa corporal. Resultados: Se evaluó a un total de 86 pacientes con una edad promedio de 56,5 años, siendo el 55 % varones y el 42 % adultos mayores. La categoría de adultos mayores tenía con mayor frecuencia peso bajo (24,4 % frente a 16,3 %, p < 0,01) y una menor frecuencia de sobrepeso (7 % frente a 15,1 %, p < 0,01) que los adultos. En ambos grupos había una frecuencia elevada de fumadores, consumo de alcohol e inactividad física. Los adultos mayores tenían un menor consumo de calorías, ingesta de hierro y ácido fólico. Se observó una ingesta inadecuada de vitaminas en ambos grupos; respectivamente, 52 %, 43 %, 95 %, 76 % y 88 % para las vitaminas A, C, D, E y el ácido fólico. Los adultos mayores tenían más ingesta inadecuada de ácido fólico y calcio que los adultos (97 % frente a 82 %, p < 0,01; 88 % frente a 72 %, p < 0,01). No hubo una asociación entre la ingesta de micronutrientes con el cáncer ni con el estado nutritivo. Conclusión: La ingesta de alimentos y de macro y micronutrientes es insuficiente en los individuos con cáncer. La ingesta de alimentos en adultos mayores fue menor en comparación con los adultos. Hubo una prevalencia elevada de IMC excesivo en el grupo de adultos y un peor estado nutricional en la categoría de adultos mayores.

Este punto de vista epidemiológico y nutricional refleja el cambio en el patrón de la enfermedad y la muerte. Objetivo: este estudio tiene como objetivo identificar los patrones de consumo de alimentos y los cambios en la dieta en el primer y tercer trimestres del embarazo. Metodología: se trata de un estudio de cohorte prospectivo de 185 mujeres embarazadas del Estado de Bahía, a partir de 2012 a 2013. Se utilizó el cuestionario de frecuencia de alimentos para evaluar la ingesta alimentaria. Para identificar la norma alimentaria se adoptó el análisis factorial de componentes principales. Se utilizó la prueba de correlación de Pearson para identificar la correlación entre los patrones extraídos en cada trimestre. Resultados: se identificaron cuatro patrones de consumo de alimentos durante el embarazo. Hemos observado cambios en los patrones de alimentación durante los trimestres evaluados, especialmente para los grupos de frutas, café, grasas, frituras, azúcar y dulces. Discusión: estos cambios en la dieta durante el embarazo acompañan a los cambios fisiológicos de cada embarazo. En el primer trimestre son síntomas comunes las náuseas y los vómitos; por otro lado, también se manifiesta antojos en el mismo periodo, lo cual puede justificar el consumo de mayor cantidad de alimentos considerados saludables. Conclusión: se observaron cambios en el patrón alimentario a lo largo de los diversos trimestres del embarazo examinados, especialmente para los grupos de frutas, café, grasas, frituras, azúcar y dulces.

Métodos: se realizó un ensayo clínico cruzado que incluyó un paso solo con dieta hipoenergética y otro con la dieta asociada con el consumo de harina de coco (26 g) a lo largo de nueve meses. Los voluntarios fueron reclutados de la ciudad de São Gonçalo de Río de Janeiro. Antropométrica, datos bioquímicos y dietéticos fueron recolectados mensualmente. Fueron evaluados el índice de calidad de la dieta revisado para la población brasileña (ICD-R) y el consumo de alimentos y aditivos ultraprocesados. Se realizaron las pruebas de Wilcoxon y Mann-Whitney, con p < 0,05, considerado estadísticamente significativo. Resultados: participaron cuarenta y dos mujeres con un promedio de 47,5 ± 9,5 años de edad. La dieta hipoenergética promovió una disminución de la grasa corporal, el índice de masa corporal, la circunferencia de la cintura, la relación cintura-talla, el índice de adiposidad visceral, la presión arterial diastólica, los triglicéridos y VLDL. El consumo de harina de coco promovió una caída en los niveles de colesterol y glucosa totales al complementar la dieta hipoenergética. La mejora de la calidad de la dieta puede observarse en la disminución del consumo de alimentos ultraprocesados como el aceite vegetal, el chocolate y los refrescos. Conclusión: la dieta hipoenergética promovió una disminución en los parámetros antropométricos, la presión arterial y los triglicéridos. El consumo de harina de coco favoreció una disminución de los niveles de colesterol y de glucosa totales cuando se complementa la dieta hipoenergética. La calidad de la dieta mejorada se puede ver en la disminución del consumo de alimentos ultraprocesados.

    This work describes the impact of the aerosols that are generated during biomass burning events in the solar irradiation, and presents a parameterization technique to improve the model estimations of the surface incident solar irradiation obtained by the BRASIL-SR radiative transfer model. It was verified that the mean systematic deviation error (MBE) of model estimates grows about 3 times and the value of root mean squared error (RMSE) duplicates in clear sky days for stations close to burned sites in central region of Brazil. The proximity of burned sites produces an increment of the same order of that produced by the presence of clouds in MBE. The parameterization technique of the biomass burning aerosols uses optical properties provided by "Global Aerosol Data Set" (GADS) and it is in accordance with measurements values obtained in two field missions: TRACE-A (1992) and SCAR-B (1995). Three different compositions were used in this study and the difference among them is the ratio of black carbon present in the aerosols: 5%, 7.8% and 10% of black carbon. These values are within the range of measured values observed in the field missions: from 4% to 12%. The aerosol profile and spatial distribution was obtained from a transport model for estimation of tracers spreading from biomass burning areas developed at INPE-CPTEC. The surface incident solar irradiation estimates, obtained with new aerosol parameterization, presented smaller systematic deviations in all the stations used in the validation process. The correlation among estimated and measured values for surface incident solar radiation grew about 2,5 times by adopting a composition with 5% of elementary carbon. The validation procedure showed that the improvements in aerosol parameterization allowed for better estimates by the model. However, the improvements are still masked by limitation imposed by the availability of only tri-hourly image schedules for the GOES-8 satellite in Southern Hemisphere

    The CLASH X-ray selected sample of 20 galaxy clusters contains 10 brightest cluster galaxies (BCGs) that exhibit significant (>5σ) extinction-corrected star formation rates (SFRs). Star formation activity is inferred from photometric estimates of UV and Hα+[N ii] emission in knots and filaments detected in CLASH Hubble Space Telescope ACS and WFC3 observations. UV-derived SFRs in these BCGs span two orders of magnitude, including two with a SFR ≳ 100 M⊙ yr-1. These measurements are supplemented with [O ii], [O iii], and Hβ fluxes measured from spectra obtained with the SOAR telescope. We confirm that photoionization from ongoing star formation powers the line emission nebulae in these BCGs, although in many BCGs there is also evidence of a LINER-like contribution to the line emission. Coupling these data with Chandra X-ray measurements, we infer that the star formation occurs exclusively in low-entropy cluster cores and exhibits a correlation with gas properties related to cooling. We also perform an in-depth study of the starburst history of the BCG in the cluster RXJ1532.9+3021, and create 2D maps of stellar properties on scales down to ˜350 pc. These maps reveal evidence for an ongoing burst occurring in elongated filaments, generally on ˜0.5-1.0 Gyr timescales, although some filaments are consistent with much younger (≲100 Myr) burst timescales and may be correlated with recent activity from the active galactic nucleus. The relationship between BCG SFRs and the surrounding intracluster medium gas properties provide new support for the process of feedback-regulated cooling in galaxy clusters and is consistent with recent theoretical predictions.

    Context. GJ 1214 b is one of the few known transiting super-Earth-sized exoplanets with a measured mass and radius. It orbits an M-dwarf, only 14.55 pc away, making it a favorable candidate for follow-up studies. However, the composition of GJ 1214 b's mysterious atmosphere has yet to be fully unveiled. Aims: Our goal is to distinguish between the various proposed atmospheric models to explain the properties of GJ 1214 b: hydrogen-rich or hydrogen-He mix, or a heavy molecular weight atmosphere with reflecting high clouds, as latest studies have suggested. Methods: Wavelength-dependent planetary radii measurements from the transit depths in the optical/NIR are the best tool to investigate the atmosphere of GJ 1214 b. We present here (i) photometric transit observations with a narrow-band filter centered on 2.14 μm and a broad-band I-Bessel filter centered on 0.8665 μm, and (ii) transmission spectroscopy in the H and K atmospheric windows that cover three transits. The photometric and spectrophotometric time series obtained were analyzed with MCMC simulations to measure the planetary radii as a function of wavelength. We determined radii ratios of 0.1173-0.0024+0.0022 for I-Bessel and 0.11735-0.00076+0.00072 at 2.14 μm. Results: Our measurements indicate a flat transmission spectrum, in agreement with the last atmospheric models that favor featureless spectra with clouds and high molecular weight compositions.

    The urban effect on lightning activity has been studied in many places around the world. The Metropolitan Region of São Paulo (MRSP) in the Southeast region of Brazil is one of the greatest and more populous urban areas of the world with a density of about 3000 inhabitants/km2. Similar to observations in other large urban areas, there is a significant enhancement in the number of negative cloud-to-ground (CG) lightning and a decrease in the percentage of positive CG flashes over the city of São Paulo. This work investigates the role of air polluted on lightning in MRSP. The CG lightning data set used was provided by Brazilian lightning detection network (BrasilDAT) for a period of 10 years (1999 - 2008). In this period, only days with CG flashes during the spring and summer seasons (from October to March) were considered and, for these days, only lightning data from 14 h to 20 h LT, were considered since this period corresponds to the time of the day with maximum lightning activity. The air polluted data set used in this work, was provided by the São Paulo environmental agencies (CETESB). The main results are: there is a tendency of increase in the ratio between lightning activity in the center area and surrounding area of the MRSP during the ten years in agreement with the same tendency observed for the number of automotive vehicles circulating on the center area of the city; there is a statistical significant increase in the CG lightning activity during the week days over MRSP related to the PM10 concentration. Apparently the increase in the lightning activity is related to an increase in the lifetime of the storms and, in consequence, the number of flashes per storm, and not to the mean flash rate of the storms. However, the increase also suggest that the effect of the pollution in the enhancement of the CG lightning activity is probably less significant compared to the effect of the urban heat island. A similar study is being done for other lightning spot

    This paper is a reflection about the use of History of Science in the curriculum of formal education, through the discussion concerning cultural elements of several ethnic groups in Brazil, in actions related to astronomy education. The work was developed in the framework of an extension course and the analysis undertaken here refers to a meeting that discussed didactic sequences relating to that theme, based on the Brazilian law 11.645/2008, which states the obligation to present the subject "African-brazilian and indigenous History and Culture" in the official curriculum. The extension action was developed with teachers who teach Natural Sciences, in São Paulo state, discussing issues related to the use of History of Science and the relationship with cosmogonies from Iorubá and Tupi peoples, highlighting how they can enhance the work with Astronomy(ies) in the classroom. It was observed that the participants had not yet presented these themes in their classes and also did not participate in training courses that discussed these subjects.

Os estudantes ficaram muito sensibilizados pela possibilidade de percepção do céu em tempo real e à luz do dia dentro da sala de aula no contexto escolar. Os resultados deste levantamento preliminar indicam que os níveis de ensino fundamental e médio não foram capazes de internalizar conhecimentos básicos de astronomia, a despeito das orientações específicas contidas nos documentos oficiais da educação básica brasileira (Brasil, 1997 e 2000). Os estudantes pesquisados apresentaram conhecimentos e concepções rudimentares sobre o tema astronomia básica, indicando a ausência de abordagem do tema astronomia, tampouco de observação direta do céu em trabalhos de campo escolares na educação básica. Finalmente, esta abordagem didática suscitou nos estudantes grande interesse para futuros trabalhos de observação de campo. D.P. Ausubel; J.D. Novak; H. Hanesian.

    Based on the readings of articles related to Astronomy Education published in Brazil, it was noticed a lack of research on previous knowledge of students about the physical characteristics of stars, a fact that motivated us to develop this study. Previous knowledge of 125 students (approximated 15 years old) constituted the study sample; data was collected through written questionnaires (Appendix A) for analysis. From the content analysis of these responses it was possible to achieve some inferences as, for example, many students have some difficult to develop an explanatory model on the functioning of a star; there are few who say that the stars have a certain length of existence; some students have said that stars have tips; few recognize that a star is formed by a mass of gas; some previous knowledge come from purely visual aspects; furthermore, some students do not have the habit of observing nature in detail. We see this research as a reference in which science teachers can recognize the importance of previous knowledge for practice teaching and acquire resources for planning their lessons. De la lectura de artículos relacionados con la Educación en Astronomía publicados en el Brasil, se encuentra una falta de investigaciones acerca del conocimiento previo de los estudiantes sobre las características físicas de las estrellas, hecho que nos motivó a desarrollar este estudio. Los datos analizados se obtuvieron al aplicar un cuestionario a 125 estudiantes de secundaria, para posteriormente realizar un análisis de contenido, tal cuestionario se presenta en el Anexo A. Al realizar el análisis de contenido de las respuestas obtenidas, fue posible hacer algunas inferencias, como por ejemplo; muchos estudiantes tienen dificultades para desarrollar un modelo explicativo acerca del funcionamiento de una estrella; pocos estudiantes dicen que las estrellas tienen un cierto tiempo de vida; algunos estudiantes imaginan que las estrellas tienen puntas; pocos

    , located 15 km to the east and to the Upper Pleistocene rhyolite from Yate volcano, approximately 100 km to the north. Geochemical data suggest that Chaiten rhyolites (both old and current eruption) were not produced by fractional crystallization of a basaltic magma derived from an astenospheric or lithospheric mantle source, as could be the case of the nearby Michinmahuida volcano. Also, Chaiten rhyolites appears to be derived from a less mafic source than the rhyolite from Yate volcano (Mella, 2008). Preliminary non-modal dynamic melting models for mafic and intermediate source suggests that 5-10 percent of partial melting of an intermediate source (modal composition including 10 Cpx, 30 Hb, 45 Pl, 4 Bt, 1 Mt) is the best fit model. As indicate by precursory and early eruption volcanotectonic seismicity, this intermediate source could be an amphibolite (facies either acquired during accretion or within the crust) located at 10-15 km depth, in a 30 km thickness crust with relatively high geothermal gradient, as it was previously proposed by Lopez et al. (1993). Crystals may be relict from the magma plumbing system. Lopez, L., Kilian, R., Kempton, P. D.., Tagiti, M. 1993. Rev. Geol.. Chile 22(1):33-55. Mella, M., 2008.

    The aim of this paper is to present a project developed through a partnership between the Astronomy Club of Itaocara Marcos Pontes (CAIMP) and Jaime de Souza Queiroz College, both located in the town of Itaocara, in the Northwest Fluminense, to disseminate Astronomy in adult education (Education for Youth and Adult). Given the interdisciplinary nature of Astronomy, we have developed this work to motivate the learning of this science by students in adult education, who attend the subjects Chemistry, Physics and Biology. Initially, we conducted a research in the school to assess the prior knowledge of Astronomy class of adult education, noting that there is little knowledge of basic concepts of the discipline. With these data, we were able to elaborate several activities that would enable a greater involvement of students with this science, performing in the school a work of improvement of scientific literacy, whose activities will be presented in this article. El objetivo de este artículo es presentar los resultados de un proyecto realizado por el Club de Astronomía de Itaocara "Marcos Pontes" (CAIMP), conjuntamente con el Colegio Estatal" Jaime de Souza Queiroz", ambos de la ciudad de Itaocara (Noroeste Fluminense - RJ, Brasil), para la difusión de la Astronomía entre los estudiantes, tanto adultos como adolescentes. Teniendo en cuenta la naturaleza interdisciplinaria de la Astronomía, se determinó motivar el estudio de esta ciencia en los estudiantes adultos de nivel secundario matriculados en las asignaturas de Química, Física y Biología. Como primer paso, se investigó el grado de conocimiento sobre astronomía del estudiante. Este estudio inicial mostró niveles de conocimiento muy bajos de los conceptos básicos de esta ciencia, muchos de los cuales deberían haber sido asimilados dentro del plan curricular del curso de Física. Este estudio previo permitió determinar las actividades adecuadas para promover un mayor envolvimiento de los estudiantes

    Unusual high-pressure inner thermal aureoles are described from the Minador and Angico Torto epidote-bearing tonalitic plutons that emplaced into greenschist-facies metasedimentary rocks of the Neoproterozoic Cachoeirinha-Salgueiro belt, northeastern Brazil. The foliated pelitic hornfelses display the mineral assemblage garnet, kyanite, staurolite, muscovite, biotite, plagioclase ± quartz. Rare fibrolite is only found very close to the contacts. Hornfelses display steep mineral lineations and steeply-dipping foliations concordant with magmatic contacts. Leucocratic veinlets containing quartz, oligoclase, garnet, kyanite, staurolite, rutile and ilmenite suggest that limited melting conditions were reached very close to magmatic contacts ( T ⩾ 650 °C, P around 8 kbar). These high-pressure hornfelses form a few meters thick, rigid envelopes around the two plutons. Contrary to known examples of kyanite-bearing hornfelses that recorded high-temperature decompression, the nearly isobaric cooling down to ca. 450 °C is constrained by 3.20-3.30 Si contents of retrogressive phengites from both inner hornfelses and ductilely-deformed tonalite at the pluton margins. Isograds and bathograds are, therefore, apparently telescoped due to HP/LT shearing, possibly caused by subsequent differential vertical movements affecting these two solidified plutons. The unusual depth of emplacement of these syn-kinematic calc-alkaline plutons is explained by a tentative geodynamic model involving a pre-620 Ma-subduction setting. Resumen Las aureolas internas que rodean dos plutones tonalíticos emplazados dentro de rocas cajas en facies esquistos verdes del Cinturón-plegado Cachoeirinha-Salgueiro al noreste de Brasil, contienen hornfelses pelíticos foliados con granate, kyanita, estaurolita, muscovita, biotita, plagioclasa ± cuarzo. Fibrolita es rara ó es encontrada solamente cerca de las zonas de contacto. Los hornfelses desarrollaron foliaciones concordantes con buzamiento fuerte

    Introducción: El objetivo del tratamiento de las fracturas abiertas es prevenir las infecciones, estabilizar el hueso e restaurar la función. En relación a los objetivos mencionados, la prevención de infecciones tiene mayor destaque y es el punto mas importante a ser alcanzado. Objetivo: El objetivo de este trabajo es identificar los factores de riesgo asociados con la infección en un grupo de pacientes con fracturas abierta de la tibia. Paciente y métodos. Fue realizado un análisis retrospectivo con pacientes que tuvieron fractura abierta tibial que estaban en tratamiento en el Hospital Roberto Santos-Geral-HGRS, Salvador, Bahía, Brasil, de marzo a octubre de 2009. Fueron excluidos de este estudio todos los niños menores de 8 años con fracturas múltiples o que tenían alguna enfermedad sistémica o en los huesos. De acuerdo con los datos clínicos y demográficos, los pacientes fueron divididos en dos grupos: el grupo 1 estaba constituido por los que no tenían infección en las fracturas y el grupo 2 por los que tenían infección. En los dos grupos se investigo factores que podrían estar asociados a la infección. Resultados. De 50 pacientes estudiados la tasa de infección global fue de 14 (28%, IC95% = 15,5-40,5). El hecho de desenvolver infección fue asociado con el lugar del trauma (OR 3,78; IC 95% = 1,4-5,5, p = 0,02), y la demora en recibir tratamiento adecuado en tiempo superior a 24 horas (OR 3,4; IC95% 1.4-20.8 = p = 0,03). Las fracturas clasificadas como Gustilo I, II, IIIA tuvieron una menor chance de infección cuando comparadas como Gustilo IIIB y IIIC (OR 4.32; CI95%=1.3-19.1; p=0.01). Fracturas clasificadas como Tscherne III y IV tuvieron una mayor frecuencia de infección, lo que resulto ser el factor más importante e significativo (OR 8.07; CI95%=2.4-47.1; p p<0.00). Conclusión.

    may have been formed during the tidal interaction of SMC-LMC that created the WH and the Magellanic bridge. Conclusions: We suggest that it is crucial to split the SMC cluster population into groups: main body, wing and bridge, counter-bridge, and WH. This is the way to analyse the complex star formation and dynamical history of our neighbour. In particular, we show that the WH has clear age and metallicity gradients and an age-metallicity relation that is also compatible with the dynamical model that claims a tidal influence of the LMC on the SMC.

    Introducción: la anemia gestacional todavía se considera un problema de salud pública en Brasil y se asocia con un mayor riesgo de morbilidad materno-fetal y el estado nutricional de los niños en el período posparto. Objetivo: evaluar la frecuencia de la anemia gestacional materna en recién nacidos y su relación con el estado nutricional del niño al nacer. Métodos: se obtuvieron datos antropométricos de las mujeres embarazadas y los recién nacidos. Se recogieron muestras de sangre de mujeres embarazadas y de cordón umbilical de los recién nacidos para su posterior análisis de hemoglobina, hematocrito, ADE, hierro, ferritina e índice de saturación de transferrina en dispositivos automatizados. Los resultados se presentan como media y la desviación estándar. Fue utilizado el software GraphPadinStat®, versión 3.0 y se aceptó un nivel de significación del 5%. Resultados: la frecuencia de anemia materna era de 53,7% y 32,6% en los recién nacidos. La mitad de los recién nacidos eran niños anémicos de madres anémicas. De las mujeres embarazadas con anemia, el 79,3% tenían anemia leve y el 20,7% moderada. La concentración media de hemoglobina y hematocrito fue menor en las mujeres embarazadas con anemia (9,7 ± 0,9 g/ dl y 29,8 ± 3,2%) en comparación con las no anémicas (11,9 ± 0,7 g/dl y 36,5 ± 2,7%), como se esperaba. El nivel de hierro de la madre se correlacionó positivamente con ferritina (r = 0,389; p = 0,01) a partir de la sangre del cordón umbilical.

    Introducción: el conocimiento del peso y la talla es fundamental en la evaluación del estado nutricional en el adulto mayor, permitiendo la implementación del proceso de cuidado nutricional. La desnutrición es común en este grupo poblacional, el cual usualmente presenta diversas situaciones clínicas que dificultan la medición de peso y talla. Objetivos: evaluar la validez de las ecuaciones para estimar peso y talla basadas en circunferencias corporales propuestas para población brasileña en adultos mayores mexicanos. Métodos: estudio comparativo, observacional, prospectivo y transversal en 61 adultos mayores. Las medidas antropométricas recolectadas fueron peso y talla, Extensión de Media Brazada (EMB), Circunferencia Abdominal (CA), Circunferencia Media de Brazo (CMB) y Circunferencia de Pantorrilla (CP). Se estimó el peso y la talla con las ecuaciones propuestas por Rabito y cols. Se utilizó el método Bland-Altman y el Coeficiente de Correlación Intraclase para evaluar la concordancia entre los valores reales y estimados. Se consideró significancia estadística un valor de p < 0,05. Resultados: la edad promedio de los participantes fue de 78,7 ± 8,7 años. El 55,7% (n = 34) fueron mujeres. La media para el peso fue de 61,9 ± 14,1 kg, para la talla de 155,4 ± 9,5 cm y para el Índice de Masa Corporal (IMC) fue de 25,5 ± 5,1 kg/m2. Mediante el método Bland-Altman los límites de intervalo de concordancia de 95% para la diferencia del peso real y el estimado fueron de -14,3 a 8,1 kg, con una media de la diferencia o error sistemático (ES) de -3,1 cm; se observó un coeficiente de 0,12 que fue estadísticamente significativo (p = 0,03). Para la talla se observa un intervalo de confianza de la diferencia entre la talla real y estimada de -11,1 a 15,9, con una media de la diferencia o ES de 2,4 cm y un coeficiente de -0,04 que no fue significativo (p = 0,67).

    Introducción: las enfermedades cardiovasculares son la principal causa mundial de morbilidad y mortalidad. Esta prevalencia justifica la importancia de los alimentos funcionales que promueven la salud cardiovascular, como el -glucano, presente en la avena, con potenciales efectos hipocolesterolémicos e hipoglucemiantes. Objetivo: evaluar los efectos de una intervención con la harina de avena en los niveles de glucosa en sangre, el índice HOMA-IR, el perfil de lípidos, el peso y el índice de masa corporal (IMC) de los usuarios adultos de un servicio de salud en Río Grande do Sul, Brasil. Métodos: estudio longitudinal, controlado, realizado con personas de 22-60 años de edad, usuarios de un servicio de salud. Los individuos fueron asignados al grupo control (dieta habitual) o grupo Case (dieta habitual + 40 g de avena/día). Al inicio del estudio y después de ocho semanas de seguimiento se evaluaron el peso y la altura, calculado IMC, la sangre recolectada para la medición de glucemia en ayunas, insulina, triglicéridos, colesterol total y colesterol HDL; y se calculó el colesterol LDL y el índice HOMA-IR. Los datos se expresan como media ± desviación estándar y porcentajes. Se aplicaron el test Kolmogorov-Smirnov, la t de Student, el test Mann-Whitney y las pruebas de Wilcoxon. Se adoptó un nivel de significación del 5% (p < 0,05). Resultados: la muestra estuvo constituida por 82 sujetos, divididos en casos (n = 38) y controles (n = 44) con una edad media de 40,07 ± 10,49 años, 58,5% mujeres. Comparando los resultados de todos los parámetros medidos al inicio del estudio y después de ocho semanas de seguimiento, el grupo de control no obtuvo una reducción significativa en ningún parámetro, mostrando un aumento significativo de la glucosa en sangre y HOMA-IR (p < 0,05). El grupo de intervención obtuvo una reducción significativa de todos los indicadores antropométricos y bioquímicos analizados (p < 0,001). Conclusión: los resultados

    Objective To assess the relationship between periodontal treatment needs by elderly Brazilians and contextual as well as individual variables. Methods A cross-sectional study was carried out to assess the need for clinical periodontal treatment, based on National Oral Health Survey (SB Brasil 2010) data on the presence of dental calculus, shallow (3–5 mm) and deep (≥ 6 mm) periodontal pockets, and gingival bleeding in elderly people (n = 7,619). The contextual variables included the Municipal Human Development Index (MHDI), income inequality (Gini Index) and coverage of the municipal population by the Family Health Strategy (FHS) program oral health teams.<0} The individual variables were sex, income, education level and self-reported skin color. Multilevel logistic regression models were used to calculate the odds ratio (OR) and 95% confidence intervals (CI95%) between periodontal treatment needs and the contextual as well as individual variables. Results Gingival bleeding was found in 20.7% of the elderly analyzed (n = 1,577), dental calculus in 34% (n = 2,590), shallow periodontal pockets in 15.6% (n = 1,189), and deep periodontal pockets in 4.2% (n = 320). Individual factors were correlated with all the outcomes assessed. Sex was a protective factor in regard to gingival bleeding (OR = 0.87; CI95% 0.76–1.00), dental calculus (OR = 0.86; CI95% 0.75–0.99), shallow periodontal pockets (OR = 0.69; CI95% 0.60–0.80) and deep periodontal pockets (OR = 0.58; CI95% 0.45–0.74). It was found that fewer women needed treatment. Elderly people who self-reported having nonwhite skin had higher chances of needing periodontal treatment. Skin color was a risk factor for gingival bleeding (OR = 1.32; CI95% 1.14–1.53), dental calculus (OR = 1.32; CI95%1.14–1.54) and shallow periodontal pockets (OR = 1.27; CI95% 1.09–1.49). Education level was associated with the presence of dental calculus (OR = 0.77; CI95% 0.66–0.89), shallow periodontal pockets (OR = 0.86; CI

    The Borborema Province of NE Brasil comprises the central part of a wide Pan-African-Brasiliano orogenetic belt that formed as a consequence of late Neoproterozoic convergence and collision of the São Luis-West Africa craton and the São Francisco-Congo-Kasai cratons. New {Sm}/{Nd} and {U}/{Pb} results from the eastern part of this province help to define the basic internal architecture and pre-collisional history of this province, with particular emphasis on delineating older cratonic terranes, their fragmentation during the Mesoproterozoic, and their assembly into West Gondwana during the Pan African-Brasiliano orogeny at ca. 600 Ma. The region can be divided into three major geotectonic domains: a) Rio Piranhas-Caldas Brandão massif, with overlying Paleoproterozoic to Neoproterozoic supracrustal rocks, north of the Patos Lineament; b) the Archean to Paleoproterozoic São Francisco craton (SFC) to the south; and c) a complex domain of Paleoproterozoic to Archean basement blocks with several intervening Mesoproterozoic to Neoproterozoic fold belts in the center (south of Patos Lineament and north of SFC). The northern and central domains comprise the Borborema Province. Archean basement gneiss and Transamazonian granulite of northern SFC are exposed in the southern part of the central domain, underlying southern parts of the Sergipano fold belt. Basement in the Rio Piranhas massif appears to consist mostly of Transamazonian (2.1 to 2.2 Ga) gneissic rocks; Nd model ages (T DM) of ca. 2.6 Ga for 2.15 Ga gneisses indicate a substantial Archean component in the protoliths to these gneisses. The Caldas Brandão massif to the east yields both Transamazonian and Archean {U}/{Pb} zircon and Nd (T DM) ages, indicating a complex architecture. Metasedimentary rocks of the Jucurutu Formation yield detrital zircons with original crystallization ages as young as 1.8 Ga, indicating that these rocks may be late Paleoproterozoic and correlate with other ca. 1.8 Ga cratonic

    the value of hydraulic machinery to the end user, to the societies, and to improve societies understanding and appreciation of that value. The series of IAHR Symposia on Hydraulic Machinery and Cavitation started with the 1st edition in Nice, France, 1960. For the past decade, all the symposia have focused on an extended portfolio of topics under the name of 'Hydraulic Machinery and Systems', such as the 20th edition in Charlotte, USA, 2000, the 21st in Lausanne, Switzerland, 2002, the 22nd in Stockholm, Sweden, 2004, the 23rd in Yokohama, Japan, 2006, the 24th in Foz do Iguassu, Brasil, 2008, and the 25th in Timisoara, Romania, 2010. The 26th IAHR Symposium on Hydraulic Machinery and Systems brings together more than 250 scientists and researchers from 25 countries, affiliated with universities, technology centers and industrial firms to debate topics related to advanced technologies for hydraulic machinery and systems, which will enhance the sustainable development of water resources and hydropower production. The Scientific Committee has selected 268 papers, out of 430 abstracts submitted, on the following topics: (i) Hydraulic Turbines and Pumps, (ii) Sustainable Hydropower, (iii) Hydraulic Systems, (iv) Advances in Computational and Experimental Techniques, (v) Application in Industries and in Special Conditions, to be presented at the symposium and to be included in the proceedings. All the papers, published in this Volume 15 of IOP Conference Series: Earth and Environmental Science, have been peer reviewed through processes administered by the editors of the 26th IAHR Symposium on Hydraulic Machinery and Systems proceedings, those are Yulin Wu, Zhengwei Wang, Shuhong Liu, Shouqi Yuan, Xingqi Luo and Fujun Wang. We sincerely hope that this edition of the symposium will be a significant step forward in the worldwide efforts to address the present challenges facing the modern Hydraulic Machinery and Systems.

    students´ teams. O docente tem importância fundamental no programa de pós-graduação, pois é quem planeja e executa grande parte das tarefas, sendo também o responsável por difundir conhecimentos aos alunos. O professor deve utilizar recursos didáticos que o qualifiquem continuamente, criando condições favoráveis para que o aluno se desenvolva e aprenda da melhor maneira e com mais facilidade. A homogeneidade no grupo de pós-graduação consiste da presença de subgrupos de pesquisa correspondentes às Áreas de Concentração, onde cada subgrupo trabalhe com algumas linhas de pesquisas diversificadas. É desejável que o corpo docente tenha significativa produção científica, de qualidade e distribuída homogeneamente entre os docentes. Estes devem sistematicamente buscar recursos em agências de fomento para pesquisa, tanto para o custeio dos estudos, quanto para a valorização dos pesquisadores envolvidos em todas as atividades. Os programas de pós-graduação precisam investir na formação de seus docentes, os quais devem aprimorar seus conhecimentos em epidemiologia de estudos clínicos, ética em pesquisa e em didática. Duas das características do sistema de pós-graduação no Brasil são a nucleação e a solidariedade, embasadas na capacidade e/ou interesse dos mais estruturados se solidarizarem com os programas iniciantes, cooperando com as suas atividades. A Capes valoriza a inserção social no contexto das atividades dos programas de pós-graduação, prevendo nos critérios de avaliação o reconhecimento de atividades com impacto tecnológico, cultural, educacional e social. Existe um modelo ideal de pós-graduação? Partimos do pressuposto de que não há uma fórmula matemática ou modelo ideal de pós-graduação e sim que cada instituição deve se adequar e buscar aperfeiçoar seu corpo docente e discente.

    We present the results obtained in a research on the comprehension of basic astronomical concepts, in which 561 students from fifth grade middle school to third grade high school of a public school of the city of Foz do Iguaçu (Brazil) took part. A test with 20 multiple-choice questions was applied to indentify the most common conceptions expressed by the students. This test was elaborated based on the literature about misconceptions and covered the following topics: the day-night cycle; the time zones; the seasons of the year; the phases of the Moon; the movement of the Moon; the apparent movement of the Sun in the celestial sphere; the eclipses; the dimensions and distances in the Universe; the brightness of the stars and its observation from Earth. Though a small progress was verified in the proportion of scientifically acceptable answers when comparing the eighth grade of middle school to the fifth, and the third grade of high school to the first, there was an overall predominance of alternative conceptions regarding most of the explored subjects, which persisted up to the last year of secondary school. The comparison to data found in this research made in other socio-cultural contexts revealed, in many aspects, similar notions and difficulties revealed by the students.

The Muriaé batholith (U-Pb age: 620-592 Ma, εNd(t): -8.2 to -13.6, Nd TDM age: 1.41-1.88 Ga) and the Conceição da Boa Vista (586 ± 7 Ma) and Serra do Valentim (605 ± 8 Ma) stocks represent a segment of the Rio Doce arc correlated to the Serra da Bolívia and Marceleza complexes, making the link between the Araçuaí and Ribeira orogenic domains. We suggest three phases of arc development: i) eastward migration of arc front (632-605 Ma), ii) widespread magma production in the whole arc (605-585 Ma), and iii) late plutonism in the western arc region (585-575 Ma). Usual processes of volcanic arc development, like subduction of oceanic lithosphere under a continental margin, followed by asthenosphere ascent related to slab retreating and break-off may explain the Rio Doce arc evolution.

    results in rising global temperatures and dramatic changes in climate which may also result in flooding in parts of our globe. Energy conservation together with replacement of coal and oil-fired power plants are, therefore, needed. The development and installation of more efficient hydroelectric power plants which work hand in hand with water storage and flood protection is part of this strategy. Waterpower is the most significant 'renewable resource'. The goals of this IAHR - Committee on Hydraulic Machinery and Systems are to improve the value of hydraulic machinery to the end user and to society and to improve society's understanding and appreciation of that value. The series of IAHR Symposia on Hydraulic Machinery and Cavitation started with the 1st edition in Nice in 1960 in France. Within the past decade, all the symposia were focused on an extended portfolio of topics under the name of 'Hydraulic Machinery and Systems', such as the 20th edition in 2000, Charlotte, USA, the 21st in 2002, Lausanne, Switzerland, the 22nd in 2004, Stockholm, Sweden, the 23rd in 2006, Yokohama, Japan, and the 24th in 2008, Foz do Iguassu, Brasil. The 25th IAHR Symposium on Hydraulic Machinery and Systems brings together more than 150 scientists and researchers from 24 countries, affiliated with universities , technology centres and industry to debate topics related to advanced technologies for hydraulic machinery and systems, which will enhance the sustainable development of water resources and hydropower production. The Scientific Committee has selected 118 papers, out of 238 abstracts submitted, on the following topics: (i) Hydraulic Turbines and Pumps, (ii) Sustainable hydropower, (iii) Hydraulic Systems, (iv) Advances in Computational and Experimental Techniques, (v) Innovative Technology, to be presented at the symposium and to be included in the proceedings. All papers published in this Volume 12 of IOP Conference Series: Earth and Environmental Science have been peer reviewed

    informe es explicar las tendencias geoquímicas y de los isótopos estables en la unidad brasileña del Sistema Acuífero Guaraní (acuíferos de Botucatu y Piramboya), en el Estado de Sao Paulo. Las concentraciones de especies disueltas y los resultados de modelaciones geoquímicas indican que el intercambio catiónico y la disolución de carbonatos desempeñan un papel importante en la evolución aguas abajo del acuífero. La disminución de calcio por el intercambio con sodio origina la disolución de carbonatos, dando lugar a aguas subterráneas de tipo bicarbonatado sódico. El frente de intercambio catiónico se desplaza a una velocidad probablemente mucho más lenta que la del flujo de agua; actualmente, se halla cerca de las ciudades de Sertaozinho y Aguas de Santa Bárbara (pozos PZ-34 y PZ-148, respectivamente), en una zona confinada somera que dista entre 50 y 70 km del área de recarga. Parte del sodio entra probablemente en el Sistema Acuífero Guaraní junto con el cloruro y el sulfato procedentes de la Formación Piramboia inferior, debido a la difusión relacionada con la disolución de evaporitas como la halita y los yesos. Se puede explicar las elevadas concentraciones de flúor (hasta 13,3 mg/L) por la disolución de fluoruro mineral, que sucede también por intercambio catiónico. Sin embargo, no está claro si la disolución ocurre directamente en el Sistema Acuífero Guaraní o en la Formación basáltica superior de Serra Geral. Hay una reducción de δ2H y de δ18O a favor del gradiente hidráulico. Hay un enriquecimiento en δ13C inorgánico aguas abajo, lo que indica que la calcita se disuelve en condiciones de sistema cerrado. Los valores de δ13C inorgánico en pozos geotérmicos profundos son muy altos (mayores que -6,0‰), y probablemente apuntan a un intercambio isotópico con carbonatos de δ13C que tiene un valor del orden del -3,0‰. Las líneas de investigación deberían centrarse en evaluar los flujos verticales y el potencial de

    flows distribution with respect the Earth's hemispheres in first caused by eccentric position of the Earth core with respect to the mantle (displaced in present geological epoch in direction to Brasil). Of course the asymmetric distribution of heat loss is a long-term phenomenon in the geological history. But in present epoch due to drift of the core to the North we must observe some increasing of the heat flow of the Northern hemisphere and decreasing of the heat flow of the Southern hemisphere. In reality mentioned changes of heat flows are contrast (asymmetrical) and can have general tendency of increasing heat flows in both hemispheres (due to activization of relative oscillations of the core and mantle relatively polar axis). Contrast secular warming of Northern and Southern hemispheres of the Earth in present epoch. Dependence of warming from latitude. And warm flows are asymmetrically, more intensively warm is redistributed in northern hemisphere of the Earth and less intensively in a southern hemisphere. From here it follows, that the phenomenon of more intensive warming up of northern hemisphere, rather than southern in present period should be observed. Data of climatic observations (in first temperature trends for various latitude belts). More detailed analysis shows, that the phenomenon of warming in different form is shown in various latitudinal belts of the Earth. This phenomenon is more clearly shown in latitudinal belts further situated on latitude from South Pole, i.e. in high northern latitudes. Really, the trend of increase of temperature in northern hemisphere is characterized by greater rate, than a trend of temperature in a southern hemisphere. And not only trend components of temperatures increase with increasing of latitudes from southern pole to northern pole, but also amplitudes of decade fluctuations of temperature in high northern breadthes are more bigger than in southern hemisphere. Thus again it is necessary to expect a contrast and

    ção máximas, principalmente em solos mais ácidos e pobres em matéria orgânico. A adubação fosfatada é muito importante no crescimento inicial da planta e, além de aumentar a produção de tuberculos em peso e números, aumenta também a quantidade e qualidade do amido neles contidos e reduz perdas durante o armazenamento dos mesmos. A quantidade de fósforo a aplicar dependerá da análise do solo considerando- se principalmente o nível de P existente e a textura do solo. Solos de textura média e arenosa necessitam maior conteúdo de fósforo do que os de textura argilosa para serem considerandos solos de baixo, médio ou alto teor de fósfato. Efeito da potássica Embora seja o elemento mais absorbido pela batateira, nem sempre há resposta positiva da aduba potássica sobre o rendimento da cultura. Provavelmente isto esteja relacionado com níveis elevados deste elemento no solo (Kurnik et all. 2001.). Entretanto, em solos com médios e baixos teores de potássio, aumentos significativos são conseguidos. Por isto, as recomendações de adubação com potássio, nas diversas regiões do mundo, variam de 50-300 kg ha-1 de K2O. Resultados de trabalhos em brasiléiros têm demonstrado que a aduba potássica pode ser substituída pela aplicação de 150 m3 ha-1 de vinhaça de cana de açúcar. Ao elevar- se a dose de fertilização potássica deverá haver precaução para que a adubação magnesiana seja suficiente. O K além de aumentar a produção, em solos deficientes, aumenta também o tamanho dos tubérculos produzidos, e a proporção de tubérculos grandes. Deficiência no suprimento de potássio á planta pode acarretar produção de tubérculos com elevada susceptibilidade aos danos mecánicos pós-colheita. Os tubérculos injuriados enegrecem facilmente e este enegrecimento é inversamente proporcional á quantidade de potássio nos tuberculos. Ademais, quando fritos dão origem a um produto escuro, de baixa valor comercial. Manejo de aduba
