    This study aimed to measure the prevalence of food insecurity in a rural area of Northeast Brazil and investigate this outcome according to residence in quilombola communities (descendants of African slaves) versus non-quilombola communities. This was a cross-sectional study in 21 rural communities, 9 of which quilombolas, in 2014, using the Brazilian Food Insecurity Scale (EBIA). Prevalence rates and prevalence ratios were estimated for food insecurity, and Poisson multiple regression analysis with robust variance was performed. Food insecurity was found in 52.1% of the families: 64.9% in quilombola communities and 42% in the others. Food insecurity was associated with belonging to a quilombola community (PR = 1.25), lower economic status (PR = 1.89; 2.98, and 3.22 for status C2, D, and E, respectively), beneficiaries of Bolsa Família program (PR = 1.52), and four or more household members (PR = 1.20). Food insecurity prevalence was high in the entire population, but it was even higher in quilombola communities, even though they belonged to the same coverage area. The results emphasize this population's vulnerability.

    Of 45 species of nemerteans reported for the Brazilian coast, only two were recorded from Brazil's Northeast coast. Here we report seven new records for the state of Ceará, in Northeast Brazil: Tubulanus rhabdotus Côrrea, 1954, Carinomella cf. lactea Coe, 1905, Baseodiscus delineatus (Delle-Chiaje 1825), Cerebratulus cf. lineolatus Coe, 1905, Cerebratulus sp. 1, Cerebratulus sp. 2 and Lineidae sp. 1. Specimens were collected at the following beaches: Praia dos Dois Coqueiros, Praia do Pacheco, Pecém harbor, Praia da Pedra Rachada and Praia do Guajiru. T. rhabdotus is a new record for Northeast Brazil, Carinomella cf. lactea and Cerebratulus cf. lineolatus are new records for the South Atlantic Ocean and both genera are new records for Brazil.

    Full Text Available We evaluated the influence of water-related human activities, contaminative behaviour, house location, education and socio-economic status on endemic Schistosoma mansoni infection. The study was conducted in a hilry non-irrigated area of rural northeast Brazil amongst a defined population of subsistence farmers, of whom 93% were infected by age 20. The area was mapped, water bodies were surveyed, and a detailed questionnaire was performed on each household. Infection was assessed by duplicate stool examinations using the sensitive Bell technique to quantify egg excretion. For each household, and index of intensity of infection was computed by grouping individual log-transformed egg counts as an age-sex adjusted Z score. Few households had a sanitary installation or a domestic water supply. However, neither water-contact nor contaminative behavior were indiscriminate. The people made considerable effort to defaecate far from a water source, to obtain household drinking water from the cleanest source, and to bathe only at certain sites where privacy is assured. Land ownership and literacy correlated poorly with the household index of intensity of infection. The key influence on infection status was the relative location of the house and snail-free or snail colonized water sources. In this area, a safe domestic water supply is the critical input needed to achieve definitive control of endemic Schistosomiasis.

    Full Text Available A comparação de mulheres como responsáveis de domicílios no Norte e no Nordeste revela efeitos de diferenciação de gênero e de histórias divergentes de migração. Como em todo o Brasil, essas mulheres têm mais instrução e menos renda que os homens responsáveis por domicílios. Fazem uso extensivo de ingressos da seguridade social, especialmente nas áreas rurais. Elas assumem mais a chefia ou quando são adolescentes, ou, muito mais, quando passam da idade de 45 anos. Recorrem mais intensivamente que homens às suas redes de relações ampliadas para inclusão de outros nas suas casas. No Norte, comparado com o Brasil e o Nordeste, com maior presença de imigração masculina, há menos mulheres chefes, em geral, e especialmente no campo. Relativamente, têm instrução superior à dos homens responsáveis. Nas suas casas há mais pessoas que nas de mulheres responsáveis em outras regiões. Só ocasionalmente moram sozinhas. No Nordeste, com uma história de emigração, as mulheres responsáveis são muito mais numerosas, em geral, com particular força no campo. A sua instrução não é tão superior à dos homens quanto à das mulheres no Norte. Elas residem sozinhas com mais freqüência e há pouca diferença no número de pessoas entre casas nas áreas urbanas e rurais.A comparison of women household heads in North and Northeast Brazil reveals effects of gender differentiation and divergent histories of migration. As in Brazil in general, women heads have more education and less income than male heads. They make extensive use of social security income, especially as a source of maintenance in rural areas. They take on headship either when adolescents, or, much more often, when over the age of 45. They include persons from their wider social networks much more than male heads do. Compared to Brazil in general and to the Northeast, the North, with a history of male immigration, has fewer women household heads in general, and

    Rural electrification is considered to be a key strategy for poverty alleviation and sustainable development. It should therefore include (1) expanding electricity access and (2) enable new consumers to increase their electricity consumption. In this paper we ask how Brazil’s recent rural electrification efforts have managed to reach these objectives. A new method to measure energy and income equity is presented which uses estimations of non-parametric density curves for the analysis of energy and income distributional trends following electrification. By applying our method to a panel data set from two Brazilian states situated in the country’s poor northeast region we find that (1) rural consumers take up electricity consumption after electrification, and that (2) low consumption levels give way to higher electricity consumption levels after only a few years. This indicates immediate social benefits for households through consumption of electricity services. However, our analysis cannot verify a direct link between electricity use and rural income generation in the short term. The results emphasize the need for government and other actors to integrate rural electrification into broader rural development strategies in order to enable long-term welfare increases through electricity use. - Highlights: ► Comprehensive analysis of Brazil’s recent rural electrification efforts. ► New methodology to analyze energy and income equity trends ex post electrification. ► Analysis indicates immediate social benefits for electrified households. ► We cannot establish a direct link between electricity use and income in the short-run. ► Electrification thus should be integrated in long-term rural development strategies.

  9. Interannual Rainfall Variability in North-East Brazil: Observation and Model Simulation

    1996-08-01

    The relationship between interannual variability of rainfall in north-east Brazil and tropical sea-surface temperature is studied using observations and model simulations. The simulated precipitation is the average of seven independent realizations performed using the Laboratoire de Météorologie Dynamique atmospheric general model forced by the 1970-1988 observed sea-surface temperature. The model reproduces very well the rainfall anomalies (correlation of 091 between observed and modelled anomalies). The study confirms that precipitation in north-east Brazil is highly correlated to the sea-surface temperature in the tropical Atlantic and Pacific oceans. Using the singular value decomposition method, we find that Nordeste rainfall is modulated by two independent oscillations, both governed by the Atlantic dipole, but one involving only the Pacific, the other one having a period of about 10 years. Correlations between precipitation in north-east Brazil during February-May and the sea-surface temperature 6 months earlier indicate that both modes are essential to estimate the quality of the rainy season.

    Participation of the author in the Interdepartmental Committee on Nutrition for National Defense sponsored nutrition surveys of Burma and northeast Brazil is described. These surveys not only collected important data on nutritional status but also guided the subsequent research interests of the author. The Brazil survey results contributed to the creation of legislation that mandated the addition of water-dispersible vitamin A to skimmed-milk powder products. This additive has greatly diminished the likelihood of vitamin A deficiency syndrome occurring in children after famine relief efforts.

    In recent years, the Brazilian government has been applying several restrictions with regard to preventing environmental pollution. Although Brazilian legislation is becoming stricter as to the pre-harvest burning of sugarcane, this practice is frequently used in order to assist manual harvesting. In the northeast region of Brazil, sugarcane is an important crop, which accounts for about 15% of the national production in a total area of 1,060,660 ha, the average production being 51,119 kg per hectare. The pre-harvest burning of sugarcane generates smoke, which has a high concentration of atmospheric pollutants such as carbon dioxide (CO2), carbon monoxide (CO), particulate matter (P.M. 2.5 and 10), polycyclic aromatic hydrocarbons (PAH), volatile organic compounds (VOC) and nitrogen oxides (NOX). This article estimates the volume of CO, P.M. 2.5 and NOX generated and how they are dispersed in the atmosphere when this arises from the burning of sugarcane biomass in rural areas of Northeast Brazil, and does so by using AERMOD VIEW® simulation software. Using the characteristics of the emissions and environmental (meteorological and topographical) data, quality air profiles based on pollutant dispersion were obtained. Three studies were taken into account in order to determine the relationship between pollutant dispersion and some parameters of the burning process, such as those for the spatial distribution of resources, the duration of pre-harvest burning and the influence of undertaking burning in different months. As to spatial distribution, to divide an area into small lots contributes to decreasing the maximum concentration of pollutants by 53% compared to burning a single area of equivalent size. The study of the burning duration indicated that doing so gradually (using a lengthier procedure) could decrease the maximum concentration of the pollutants by an inverse relation. The harvesting period in this region is between November and April. The pollutants

    Climate simulations were performed using a regional model (Regional Atmospheric Modeling System, RAMS 6.0) driven by data from one of the CMIP5 models (Hadley Centre Global Environmental Model, version 2 - Earth System, HadGEM2-ES) over two CORDEX domains (South America and Central America) for the heavy-emission scenario (RCP8.5). Potential evapotranspiraion data from the RCM and from the CMIP5 global models were analyzed over Northeast Brazil, a semiarid region with a short rainy season (usually February to May in its northern portion due to the seasonal shift of the Intertropical Convergence Zone) and over which droughts are frequent. Significant changes in the potential evapotranspiration were found, with most models showing a increasing trend along the 21st century, which are expected to alter the surface water budget, increasing the current water deficit (precipitation is currently much smaller than potential evapotranspiration). Based on the projections from the majority of the models, we expect important impacts over local agriculture and water resources over Northeast Brazil.

    Despite all efforts to store and reduce its consumption, water is becoming less inexhaustible and its quality is falling faster. Considering that water is essential to animal life, it is necessary to adopt measures to ensure its sanitary conditions in order to be fit for consumption. The aim of this study was to analyze the microbiological quality of drinking rainwater used by rural communities of Tuparetama, a small town located in Northeast Brazil. The study covered seven rural communities, totaling 66 households. In each household two samples were collected, one from a tank and the other from a clay pot located inside the home, resulting in 132 samples (tank plus clay pot). Approximately 90% of samples were below the standard recommended by the current legislation, being considered unfit for human consumption. Part of this high microbiological contamination of drinking rainwater could be related to the lack of sanitary education and of an adequate sewerage sanitation system.

    Full Text Available Population-based data on sexually transmitted infections (STI, bacterial vaginosis (BV, and candidiasis reflect the epidemiological situation more accurately than studies performed in specific populations, but such data are scarce. To determine the prevalence of STI, BV, and candidiasis among women of reproductive age from a resource-poor community in Northeast Brazil, a population-based cross sectional study was undertaken. All women from seven hamlets and the centre of Pacoti municipality in the state of Ceará, aged 12 to 49 years, were invited to participate. The women were asked about socio-demographic characteristics and genital symptoms, and thereafter examined gynaecologically. Laboratory testing included polymerase chain reaction (PCR for human papillomavirus (HPV, ligase chain reaction (LCR for Chlamydia trachomatis and Neisseria gonorrhoeae, ELISA for human immunodeficiency virus (HIV, venereal disease research laboratory (VDRL and fluorescent treponema antibody absorption test (FTA-ABS for syphilis, and analysis of wet mounts, gram stains and Pap smears for trichomoniasis, candidiasis, and BV. Only women who had initiated sexual life were included in the analysis (n = 592. The prevalences of STI were: HPV 11.7% (95% confidence interval: 9.3-14.7, chlamydia 4.5% (3.0-6.6, trichomoniasis 4.1% (2.7-6.1, gonorrhoea 1.2% (0.5-2.6, syphilis 0.2% (0.0-1.1, and HIV 0%. The prevalence of BV and candidiasis was 20% (16.9-23.6 and 12.5% (10.0-15.5, respectively. The most common gynaecological complaint was lower abdominal pain. STI are common in women in rural Brazil and represent an important health threat in view of the HIV pandemic.

    Semi-arid areas are characterized by small water resources. An increasing water demand due to population growth and economic development as well as a possible decreasing water availability in the course of climate change may aggravate water scarcity in future in these areas. The quantitative assessment of the water resources is a prerequisite for the development of sustainable measures of water management. For this task, hydrological models within a dynamic integrated framework are indispensable tools. The main objective of this study is to develop a hydrological model for the quantification of water availability over a large geographic domain of semi-arid environments. The study area is the Federal State of Ceara in the semi-arid north-east of Brazil. Surface water from reservoirs provides the largest part of water supply. The area has recurrently been affected by droughts which caused serious economic losses and social impacts like migration from the rural regions. (orig.)

    This anthropological study critically evaluates Brazilian caregivers' symbolic production and significance of their malnourished offspring's primary teeth, as well as their own, and describes popular dental practices. From January to June 2004, ethnographic interviews of 27 poor, low-literacy mothers were conducted at a public Malnutrition Treatment Center in Fortaleza, Ceará State. Participant observation of clinical pathways and home environments supplemented the data. Content analysis was performed. Results confirm that primary teeth are imbued with cultural significance in Northeast Brazil. Mothers examine mouths, perceive signs of decay, associate primary with permanent tooth healthiness, identify ethnodental illnesses, seek assistance, and perform rituals with exfoliated teeth. The mother's motivation to care for primary teeth is sparked by her memories of past toothache and attempts to avoid stigma and discrimination. Social determinants, not mothers' beliefs or behaviors, are the most critical obstacles to effective dental care. Legitimizing lay knowledge and empowering caregivers and children can improve oral health in Northeast Brazil.

    Coccidioidomycosis is a systemic infection caused by Coccidioides spp. The disease is endemic in Brazil but its incidence is underreported as it is not a notifiable disease. This article presents the results of a serologic survey carried out with 229 volunteers in northeast Brazil by the immunodiffusion (ID) test with commercial Coccidioides spp. antigens. The commercial ID test detected 15 individuals without clinical diagnosis of the disease and two individuals in treatment for coccidioidomycosis. Regarding the epidemiological data, most of the positive individuals were male, between 18 and 65 years of age and were engaged in armadillo hunting. Three women who had never participated in armadillo hunts also displayed positive results for coccidioidal antibodies. Besides armadillo hunts, exposure to environmental dust in endemic areas may account for the serologic response detected in the study. The data from this study suggest the importance of performing epidemiological surveys for coccidioidomycosis in order to understand the prevalence of this disease in Brazil.

    The last study reported the prevalence of Metabolic Syndrome (MetS) in rural Northeast China was conducted approximately ten years ago. We aimed to update the data on the prevalence and epidemiological features of MetS in rural Northeast China. This survey was conducted from July 2012 to August 2013. In this study, a total of 11,496 residents from the rural Northeast China were randomly selected and examined. MetS was defined according to the ATPIII-modified criteria. Data regarding the demographic and lifestyle characteristics and the blood biochemical indexes of these participants were collected by well-trained personnel. The prevalence of MetS was 39.0% and was more prevalent in women than in men (45.6% vs. 31.4%, P 20,000 CNY per year, longer sleep duration (>9 h/d), chronic disease status, frequent consumption of beans or bean products and frequent tea drinking. Completion of education through middle school, moderate physical activity and smoking were correlated with lower rates of MetS. The prevalence of MetS was high in the rural areas of China, especially among females. In addition to some of the more conventional risk factors associated with MetS, including age, sex, annual income and educational status, we also found that having more than one child and frequent consumption of tea and beans were risk factors for MetS, while smoking was a common factor among those that did not have MetS in rural Northeast China.

    Market-led economic reforms are usually viewed as being in conflict with government-stimulated socioeconomic development for disadvantaged groups. Nevertheless, Ceará, a poor state in the Northeast of Brazil, has since 1987 pursued both of those strategies simultaneously. One part of that approach has been a program of nurse-directed auxiliary health workers serving about 5 million people--almost all the persons outside the capital city and half of those in the capital. The system requires that the auxiliaries, called agentes de saúde, live in the local communities that they serve. The health agents visit each home once a month to carry out a small number of priority health activities. While health agent positions are in high demand, the minimum-wage salary that the agents receive makes up only a small portion of the state budget. A key aspect of the system is timely and comprehensive information, which is based on agent visits and is managed by trained nurses. Since the health agents system was launched, there has been a rapid decline in infant mortality, a rapid rise in immunization, identification of bottlenecks limiting the utilization of other medical resources, and timely interventions in times of crisis. The health agents system has combined administrative decentralization with financial centralization during a period of electoral democratization. The system has strengthened Ceará's commitment to primary care even as market-oriented changes have reduced the overall role of government. The Ceará program is being copied throughout the Northeast and other regions of Brazil. The key role that nurses play in the Ceará program in organizing and leading a system of basic primary care in poor neighborhoods and rural areas may provide useful lessons for other countries. In addition, Ceará does not have many of the favorable characteristics of other countries that have successfully invested in primary health care. Ceará thus represents a more achievable model

    In an ideal world, rural electrification would serve the goal of socio-economic development. Improved electricity access can power rural industries, enhance agricultural productivity, and provide households with more productive time for study and work at night. Brazil's national rural electrification program has promised to target poor and remote rural communities, but has this goal been met? We analyze statistically representative data from Brazil's Census of 2000 and 2010. While Brazil has reached municipalities with low initial electricity access rates, rural electrification has not targeted the least developed municipalities. Furthermore, we find that the government has not reached the most remote and sparsely populated rural communities. Primary policy implications include more precise targeting of the least developed municipalities, complementary interventions to promote rural development, and increasing investments into distributed energy, such as off-grid solar power. With these strategies, Brazil and other countries facing similar issues can enhance the socio-economic benefit of rural electrification. - Highlights: • Progress of rural electrification in Brazil, 2000–2010. • Low initial electrification rates predict high achievement. • Lack of socio-economic development predicts neither high nor low achievement. • Remoteness predicts low achievement.

    Full Text Available The rural population lives in socioeconomic inequality conditions motivated by several problems, including an insufficient sewage systems and water supply, these, sometimes, most responsibles by the appearance of waterborne diseases that contribute to the rise of child mortality and other problems. Rural areas in Brazil are defined by opposition and exclusion in urban areas. This definition is arbitrary and physical-geographic, not considering the social and economic processes involving the territories. This study purposed to verify, by means of sociodemographic aspects, environmental sanitation and main grievances/diseases importance for public health of the population from forest field and water, if the most rural municipalities (MMR are more precarious than the more urban (MMU. To this end, was carried out a descriptive study based on secondary sources (Atlas of Human Development in Brazil, IBGE census, PNAD and Sinan. Among the results, it follows that the rural population identified by IBGE boils down to 15.6% of Brazil’s population. In 29% of the municipalities, the population living in rural areas exceeds the city. The higher frequencies from IDMH very low are for MMR, while the higher frequency from IDMH very high and high are for MMU. In health, the MMR also exhibit deficiency. It was observed high incidence rates of diseases related to poor conditions of sanitation. From these results, it was identified a more precarious health profile in MMR when compared to MMU.

    Full Text Available Organizational theory has long emphasized the importance of contingent, environmental influences on organizational performance. Similarly, research has demonstrated the importance of local political culture and informal management on the performance of the local health system, establishing vicious and virtuous circles of influence that contribute to increasing inequalities in performance among decentralized local health systems. A longitudinal ethnography studied the relationship between these elements in the same rural municipality in Northeast Brazil after a four-year interval. The second study found the local health system performance much improved. Two main factors appear to have interacted to bring this about: leadership vision and power to implement of one individual; professionalization of the local health system by hiring a significant number of senior health staff. The origins of these influences combine initiatives at local, state and federal levels.

    Full Text Available Although the use of wild mammals as a source of food has been better studied in tropical forest environments, their importance as a source of protein for human communities in semiarid environments is little known. In the latter, the availability of wild animal meat is limited in comparison to other environments. In the semiarid regions of northeastern Brazil, hunting wild mammals for their meat is traditional, playing a crucial role in the livelihoods and food security of various rural and urban communities, especially during the annual drought seasons. In this study, we investigated the role of wild mammals as bushmeat in 10 communities within the Caatinga biome in northeast Brazil. We used key-informant interviews, household surveys, and questionnaires to determine the species hunted and consumed. We found that about 30 species were used for bushmeat, with communities clustering into two main groups. We showed that in almost all municipalities visited, all mammals hunted were reported after interview days. A total of 46.9% of hunters consumed bushmeat at least once a week. However, preference for bushmeat over livestock was perceived to be more a matter of taste (61.50% of respondents than a real need for protein supplementation from the wild. The ease of entering environmental areas where wild mammals can be found has disadvantages for wildlife in terms of pressure and overexploitation, especially where it concerns endangered species. The key to understanding the socioeconomic, cultural, and ecological contexts in which there are traditional uses is to develop conservationist strategies suitable for the socioeconomic reality of human populations.

    Land degradation deteriorates biological productivity and affects environmental, social, and economic sustainability, particularly so in the semi-arid region of Northeast Brazil. Although some studies exist reporting gross measures of soil microbial parameters and processes, limited information is available on how land degradation and restoration strategies influence the diversity and composition of soil microbial communities. In this study we compare the structure and diversity of bacterial communities in degraded and restored lands in Northeast Brazil and determine the soil biological and chemical properties influencing bacterial communities. We found that land degradation decreased the diversity of soil bacteria as indicated by both reduced operational taxonomic unit (OTU) richness and Shannon index. Soils under native vegetation and restoration had significantly higher bacterial richness and diversity than degraded soils. Redundancy analysis revealed that low soil bacterial diversity correlated with a high respiratory quotient, indicating stressed microbial communities. By contrast, soil bacterial communities in restored land positively correlated with high soil P levels. Importantly, however, we found significant differences in the soil bacterial community composition under native vegetation and in restored land, which may indicate differences in their functioning despite equal levels of bacterial diversity.

    Full Text Available Abstract The mangrove oyster Crassostrea rhizophorae is an estuarine resource exploited by riverside communities in Northeast Brazil. Despite its socioeconomic importance, studies on the health status of this bivalve are scanty in this region. The purpose of the present study was to investigate the presence of the protozoan Perkinsus sp. in C. rhizophorae collected in August and September 2011 in three estuaries of the septentrional Northeast, Brazil: Jaguaribe (Ceará, Camurupim (Piauí and Carnaubeiras (Maranhão (n= 150 specimens/site. The samples were submitted to Ray’s fluid thioglycollate medium (RFTM, PCR and histology assays. The RFTM assay revealed spherical, blue or bluish-black hypnospores of the genus Perkinsus in 50 specimens (Jaguaribe= 17.3%, Camurupim= 5.3%, Carnaubeiras= 10.6%. The intensity of the infection ranged from very light (1-10 cells per slide to severe (more than 40 cells in each of 10 fields of the slide for Jaguaribe; very light for Camurupim and very light to moderate (at least 40 cells observed in each of 10 fields of the slide for Carnaubeiras. When submitted to confirmatory PCR analysis, 6 cases were confirmed (Jaguaribe=3, Camurupim=1, Carnaubeiras=2. The histology confirmed 21 cases of infection in specimens from the three estuaries. Although local collectors have reported no mortality in oyster populations that might be attributed to infection by Perkinsus, health surveillance of oyster populations in the septentrional region of Northeast Brazil is advisable.

    Full Text Available Rural extension is a complex practice that involves the provision of technical assistance and advisory services to farmers and other rural actors with the aim of improving agricultural production as well as organizational and commercial dynamics. Thus, it is clear that rural extension as an interdisciplinary practice that requires contributions from different social sciences. In consequence, it can be argued that psycholog y has a great potential to contribute to rural extension. Nonetheless, it has been mentioned that its contributions to the topic have been scarce. Aiming to understand the potential role of psychologists in the context of rural extension, a qualitative, exploratory-descriptive research was conducted. A total of 40 extensionists from the Argentine northeast provinces were interviewed. Interviews were recorded and latter analyzed following grounded theory’s guidelines and using Atlas Ti software. The findings allow concluding that most rural extensionists consider that psycholog y could contribute to their practice, but without being able to clarify its specificities. Additionally, exten-sionists highlight potential contributions in the area of group dynamics, conflict management and the understanding of farmers’ behavior.

    This article reports historical ethnobotany research conducted from a study of the work Historia Naturalis Brasiliae (Natural History of Brazil), authored by Piso and Marcgrave and published in 1648, with main focus on Caatinga of northeast region of Brazil. Focusing the content analysis on the section dedicated to plant species with multiple uses, Marcgrave's contribution to the aforementioned work, this research had the following objectives: the retrieval of 17th century knowledge about the food uses of the flora in the northeast region of Brazil, including the taxonomic classifications; the identification of plant parts, their modes of consumption and the ethnic group of consumers; and the verification of the use of these species over time. The use of 80 food species at the time of the publication of the work is indicated, some of which are endemic to the Caatinga, such as "umbu" (Spondias tuberosa Arruda), "mandacaru" (Cereus jamacaru DC.) and "carnauba" (Copernicia cerifera Mart.). It is noticeable that among the species listed by Marcgrave, some species still lack current studies indicating their real nutritional value. The present study is an unprecedented work because it introduces, in a systematic way, the food plants described in a study of 17th century Brazil. Finally, this study makes information about plants consumed in the past accessible, aiming to provide material for studies that could develop new food products today.

    Full Text Available ABSTRACT Knowledge of weed floristic composition and phytosociology are key factors for improving weed management in pastures. Information on weed species that occur in pastures in Northeast Brazil, particularly in Maranhão State is very limited. It is, therefore, important, to search for information to help farmers to control weeds in livestock farming. This paper describes the weed flora diversity and community structure parameters, including density, frequency, abundance and importance value for each weed species found in five pastures of same age and management in Maranhão State, Northeast Brazil. The weed survey was carried out using a wooden frame (80 cm x 30 cm placed randomly on the soil surface 30 times in each pasture (n = 150. Weeds were pulled out, separated by species and counted. The weed flora was represented by 996 individuals, from nine families, 15 genera and 19 species. Weed density within pastures was of 44.3 plants m-2. The weed flora was dominated by species of the Cyperaceae and Poaceae families. The most important weed species based on Importance Value were Eragrostis ciliaris (IV = 32.97, Cyperus rotundus (IV = 31,95, Cyperus luzulae (IV = 27,50, Cyperus sphacelatus (IV = 27,42, Pycreus lanceolatus (IV = 27,33 Cyperus haspan (IV = 25,72 and Eleusine indica (IV = 23,49. Weed diversity, based on Shannon Diversity Index was very high (H' = 4.37 nats ind-1. Our results could lead to improved weed management in pastures in Maranhão State, Northeast Brazil.

    Rural-urban differences in the prevalence of chronic diseases in the adult population of northeast China are examined. The Jilin Provincial Chronic Disease Survey used personal interviews and physical measures to research the presence of a range of chronic diseases among a large sample of rural and urban provincial residents aged 18 to 79 years (N = 21 435). Logistic regression analyses were used. After adjusting for age and gender, rural residents had higher prevalence of hypertension, chronic ischemic heart disease, cerebrovascular disease, chronic low back pain, arthritis, chronic gastroenteritis/peptic ulcer, chronic cholecystitis/gallstones, and chronic lower respiratory disease. Low education, low income, and smoking increased the risk of chronic diseases in rural areas. Reducing rural-urban differences in chronic disease presents a formidable public health challenge for China. The solution requires focusing attention on issues endemic to rural areas such as poverty, lack of chronic disease knowledge, and the inequality in access to primary care. © 2014 APJPH.

    Full Text Available Abstract Background Previous researches aiming to estimate the association between metabolic syndrome and depressive symptoms come out with inconsistent results. Besides, most of them are conducted in the developed areas. There is lack of the data from rural China. The aim of this study is to confirm whether gender difference exists among the relationship between MetS, metabolic components and depressive symptoms in the rural Chinese population. Methods A cross-sectional analysis enrolled 11430 subjects’ aged ≥35 from rural Northeast China. Metabolic and anthropometric indicators were measured according to standard methods. Depressive symptoms were defined using the Patient Health Questionnaire-9 (PHQ-9. Results The prevalence of depressive symptoms was 6% among rural Northeast general population and the prevalence of MetS and its components were 39.0% for MetS, 42.9% for abdominal obesity, 67.1% for elevated blood pressure, 47.1% for hyperglycemia, 32.1% for hypertriglyceridemia, 29.5% for low HDL-C. Depressive symptoms were associated with triglyceride component (OR = 1.24, 95%CI: 1.05–1.46, P = 0.01 but not MetS (OR = 1.11, 95%CI: 0.94–1.30, P = 0.23. Moreover, depressive symptoms were associated with triglyceride component (OR = 1.21, 95% CI = 1.00–1.47, P = 0.05 in women only. But once adjusted for menopause status, depressive symptoms were no longer statically associated with triglyceride component (OR = 1.20, 95% CI = 0.99–1.46, P = 0.07. Conclusions Depressive symptoms were associated with triglyceride component but not MetS in rural Chinese population. Routine lipid screening should be recommended among rural depressed residents especially among female.

    This was a cross-sectional study within Brazil's Project for the Expansion and Consolidation of Family Health, 2005, with the objective of universal and free access to the medication prescribed in the last medical appointment for acute health problems and to estimate the degree to which access may have improved with inclusion of the medicines in prevailing policies and programs. The sample included 4,060 adults living in the area of primary health care units in 41 municipalities in South and Northeast Brazil. Access was greater in the South (83.2%) than in the Northeast (71%), and free access was similar (37%), with a greater share by the Family Health Program (FHP) when compared to the traditional model, especially in the Northeast. Some 60% of prescribed medicines and 50% of those on the National List of Essential Medicines (RENAME) were paid for. No variation was observed in the proportion of medicines present on the prevailing RENAME list and access. However, 40% of the medicines that were paid for can currently be obtained through the Popular Pharmacy Program. The latter program appears to emerge as a new way to guarantee access to medicines prescribed in the health system.

    We aimed to determine the association of atherogenic index of plasma (AIP) with hyperuricemia (HUA) in the rural population of northeast China. This cross-sectional study was conducted in the rural areas of northeast China from January 2012 to August 2013, and the final analysis included data obtained form 5253 men and 6092 women. 1104 participants (9.7%) suffered from HUA. Spearman rank test showed that AIP was positively correlated with uric acid in both sexes (r = 0.310 for men and r = 0.347 for women, both p 0.21) risk. The prevalence of HUA increased with AIP. Multivariate logistic regression analysis showed that, compared to the low AIP group, participants in increased AIP group had a 2.536-fold risk for HUA (2.164-fold in male and 2.960-fold in female) after adjustment for covariates. Results of receiver operating characteristic curves showed that the area under the curve (95% confidence intervals) was 0.686 (0.665-0.707) for male and 0.730 (0.706-0.755) for female. We indicated that increased AIP was associated with higher serum uric acid levels and could be identified as an independent risk factor of HUA in the rural population of northeast China.

    Full Text Available The number of visceral leishmaniasis (VL cases has increased over the past 10 years in Brazil, especially in the North and Northeast regions of the country. The aim of this study was to evaluate the urbanisation of VL vectors in Barcarena, Pará, an area in northern Brazil where VL is endemic. Sandflies were captured using Centers for Disease Control (CDC light traps along an urban-rural gradient. The CDC traps were installed inside hen houses at a height of 150 cm. A total of 5,089 sandflies were collected and 11 species were identified. The predominant species was Lutzomyia longipalpis (rate of 95.15%, which suggests its participation in the transmission of VL. A total of 1,451 Lu. longipalpis females were dissected and no Leishmania infections were detected. Most of the sandflies were captured at the border of a forest (88.25% and no flies were captured in the urban area, which suggests that transmission is still restricted to rural sites. However, the fact that a specimen was collected in an intermediate area indicates that urbanisation is a real possibility and that vector monitoring is important.

    Work on the prospects for alternative energy systems, especially solar and biomass, and the interrelationship of energy and rural development in the semi-arid areas of North-East Brazil is reported. The approach is interdisciplinary and raises questions about some economic and social costs and benefits that may be associated with energy-policy choices in this one sub-region of Brazil. Following an appraisal of fuel wood, solar cookers, irrigation and fertilizers in the context of energy and rural development, the social, demographic and cultural characteristics of the region are described. The drought-stricken area of the rural Northeast (Sertao) is the poorest in the country, with small land units, scarce surface water, subsistance agriculture, low capital formation, transportation deficiencies, resistance to change, high rates of out-migration and the like. The description of some regional development projects leads to a comparison of various technologies that might efficiently improve the supply of water. Work performed in the State of Paraiba on simple water distillation technology is reviewed and a social and economic cost/benefit study proposed. Factors affecting rural electrification are considered. A social impact analysis of viable alternatives to conventional electrical energy systems is put forward and the status of wind and solar generation of electricity is reviewed. A final section describes the current status of work in Brazil on biomass alternatives and compares the prospects for sugar cane and manioc plant alcohol. A proposal is made for a multi-disciplinary assessment of the socio-economic impacts of alternate energy sources. 42 references.

    This work describes the development of a management and planning system on a GIS (Geographic Information System) platform destined to decision makers that is, administrators, planners or consultants in renewable energies. It was conceived to deal with the management and planning of solar systems, biomass and aeolics in rural regions of Brazil. The prototype of the GIS tool covers an area of 183, 500 km{sup 2} and is made up of three blocks: management of installed renewable systems, inclusion (planning) of new systems and updating of the data banks. The GISA SOL 1.0 (Geographic Information System Applied to Solar Energy) has a total of 80 layers of information that permit the realization of spatial analyses on management and planning of renewable sources of energy at macro-spatial (state) and local (municipality) levels. A description and the methodology used for its development and a description of the functionalities will be made here. The system was developed mainly for PV systems as a support tool for management and planning of the Energy Development Program for States and Municipalities (PRODEEM), a program for inclusion in large scale of solar photovoltaic energy in the rural environment, conducted by the Ministry of Mines and Energy of Brazil.

Other studies, in nearby regions, after the discovery of uranium, found soils rich in heavy rare earth elements, making the region the focus of research of several public and private companies. Currently, it is not occurring mineral exploration in the region, but the rumors about the presence of rocks and stones that cause cancer are always present in the everyday life of the population. Periodically, researchers are visiting Sao Jose de Espinharas to obtain samples of water, soil, and rock, and then new comments arise on the likely transference of the population due to uranium occurrence in urban and rural areas. Urban and the rural area inhabitants hamper or obstruct the work of collection due to ignorance about the phenomenon of natural radioactivity. The main objective of this work is to promote the necessary to highlight the need to develop knowledge about local environmental radioactivity and the benefits and problems due to the existence of uranium ore. There are still no results about public awareness on the subject in the region, but it is expected that in a few months can be assessed the implemented actions as multipliers of knowledge of the region to disseminate basic knowledge about natural radioactivity.

    Based on a qualitative study conducted in 2012, the article analyzes middle-class individuals' experiences with induced abortions performed in private clinics. Thirty-four stories of induced abortions were narrated by 19 women and five men living in two state capitals in Northeast Brazil. Thematic analysis revealed differences in types of clinics and care provided by the physicians. The article shows that abortion in private clinics fails to guarantee safe or humane care. The narratives furnish descriptions of diverse situations and practices, ranging from flaws such as lack of information on medicines to others involving severe abuses like procedures performed without anesthesia. The article concludes that criminalization of abortion in Brazil allows clinics to operate with no state regulation; it does not prevent women from having abortions, but exposes them to total vulnerability and violation of human rights.

    Full Text Available Abstract Coconut water is considered to be a natural isotonic drink and its marketing is gradually increasing. The objective of the present study was to evaluate the microbiological quality of the coconut water produced and bottled in the Northeast of Brazil. Products form ten industries from different states in the Northeast of Brazil were analyzed. The most probable number (MPN method was used to quantify the coliforms. Samples showing positive for coliforms were seeded on ChromAgar Orient plates and the bacteria identified from isolated colonies using the automated system Vitek 2 (BioMérieux, according to the manufacturer's instructions for the preparation of the inoculum, incubation, reading and interpretation. The samples showed thermotolerant coliform counts between 6.0×102 and 2.6×104 MPN/100 mL. The presence of Klebsiella pneumoniae, Morganella morganii and Providencia alcalifaciens was observed. The implementation of preventive methods and monitoring of the water quality by the industries is required.

    Introduction Cutaneous leishmaniasis (CL) is a vector-borne disease of increasing importance in northeastern Brazil. It is known that sandflies, which spread the causative parasites, have weather-dependent population dynamics. Routinely-gathered weather data may be useful for anticipating disease risk and planning interventions. Methodology/Principal Findings We fit time series models using meteorological covariates to predict CL cases in a rural region of Bahía, Brazil from 1994 to 2004. We used the models to forecast CL cases for the period 2005 to 2008. Models accounting for meteorological predictors reduced mean squared error in one, two, and three month-ahead forecasts by up to 16% relative to forecasts from a null model accounting only for temporal autocorrelation. Significance These outcomes suggest CL risk in northeastern Brazil might be partially dependent on weather. Responses to forecasted CL epidemics may include bolstering clinical capacity and disease surveillance in at-risk areas. Ecological mechanisms by which weather influences CL risk merit future research attention as public health intervention targets. PMID:25356734

    One of the technologies that stand out as an alternative to provide additional flexibility to power systems with large penetration of variable renewable energy (VRE), especially for regions with high direct normal irradiation (DNI), is concentrated solar power (CSP) plants coupled to thermal energy storage (TES) and back-up (BUS) systems. Brazil can develop this technology domestically, especially in its Northeast region, where most of VRE capacity is being deployed and where lies most of the CSP potential of the country. This work applies the Capacity Expansion Model REMix-CEM, which allows considering dispatch constraints of thermal power plants in long-term capacity expansion optimization. REMix-CEM calculates the optimal CSP plant configuration and its dispatch strategy from a central planning perspective. Results showed that the hybridization of CSP plants with jurema-preta biomass (CSP-BIO) becomes a least-cost option for Brazil by 2040. CSP-BIO contributes to the Northeast power system by regularizing the energy imbalance that results from the large-scale VRE expansion along with conventional inflexible power plants. CSP-BIO plants are able to increase frequency response and operational reserve services and can provide the required additional flexibility that the Northeast power system of Brazil will require into the future. - Highlights: • Concentrating solar power (CSP) plants provide flexibility to power systems. • CSP configuration is optimized endogenously during capacity expansion optimization. • CSP hybridized with biomass supports grid-integration of variable renewable energy. • CSP become the least-cost option for the Northeast power system of Brazil by 2040.

    1. The Antillean manatee (Trichechus manatus manatus), a subspecies of the West Indian manatee, is a large-bodied marine mammal found in fresh, brackish, and marine habitats throughout the Caribbean Islands and Central and South America. Antillean manatees in Brazil are classified as critically endangered, with a census size of approximately 500 individuals. The population in the Northeast region of Brazil is suspected to have approximately 300 manatees and is threatened by habitat alteration and incidental entanglement in fishing gear. 2. A high incidence of dependent calf strandings have been identified near areas of altered critical manatee habitat. The majority of the calves are neonates, discovered alive, with no potential mothers nearby. These calves typically require human intervention to survive.

    This study extends phenotypic and ecological knowledge of Coccidioides spp., by describing its recovery from soils of Ceará State (Northeast Brazil) and analyzing the in vitro features of the growth of its vegetative phase. Following a human coccidioidomycosis case, Coccidioides spp. strains were isolated from 3 of 14 soil samples collected in an armadillo's burrow. Mycological analysis showed colonies with glabrous, velvety or cottony texture and an increasing quantity of arthroconidia. The overall growth rates of the strains were slower in 8% NaCl medium, maximum growth rate was obtained at 30 degrees C, and their pH tolerance ranged from 4.0 to 11.0. Several carbohydrates and polyalcohol sources could be efficiently metabolized by Coccidioides spp. strains in the mycelial form. Total absence of growth was observed in media supplemented with either L-aspartic acid or L-histidine. Whereas intense growth was found when strains were incubated with any other aminoacid sources studied. Coccidioides spp. strains did not grow in the presence of Tween 60 and Tween 80, but exhibited intense growth in Tween 20. Nicotinic acid and the toxic compounds caffeic acid and phenol could not be metabolized by any strain. All of the strains were positive for urease production and displayed intense growth in media containing cycloheximide concentrations ranging from 0.01 and 0.05%, but did not grow at 0.1 and 0.2%. The present findings confirm the importance of armadillos burrows in the ecology of Coccidioides spp. in Northeast Brazil and indicate that the fungus is a very physiologically versatile organism.

    Full Text Available Of late, there have been several political, practical and analytical changes to our understanding of rural development. Diverse efforts have emerged in the analysis and discussion of spatial dynamics such as “rurality”, territories, in the construction of a territorial perspective of rural development. These changes in the forms of identification and measurement of rural development lead us to question the validity and effectiveness of applied methods, inviting us to establish methodologies and analytical criteria coherent with the multiple manifestations and scales of development. This article offers a multidimensional and multi-scalar analytical model for territorial rural development, using our methodology tested in four rural territories of Brazil.

    There has been an increasing concern about current environmental issues caused by human activity, as the world searches for development. The production of electricity is an extremely relevant factor in this scenario since it is responsible for a large portion of the emissions that cause the greenhouse effect. Due to this fact, a sustainable development with alternative energy sources, which are attractive for such purpose, must be proposed, especially in places that are not supplied by the conventional electricity grid such as many communities in the Northeast Brazil. This work aims to calculate the environmental cost for the alternative sources of energy - solar, wind and biomass - during electricity generation, and to estimate the economic feasibility of those sources in small communities of Northeast Brazil, considering the avoided costs. The externalities must be properly identified and valued so the costs or benefits can be internalized and reflect accurately the economic feasibility or infeasibility of those sources. For this, the method of avoided costs was adopted for the calculation of externalities. This variable was included in the equation developed for all considered alternative energy sources. The calculations of economic feasibility were performed taking the new configurations in consideration, and the new equation was reprogrammed in the Programa de Calculo de Custos de Energias Alternativas, Solar, Eolica e Biomassa (PEASEB). The results demonstrated that the solar photovoltaic energy in isolated systems is the most feasible and broadly applicable source for small communities of Northeast Brazil. (author)

    Coccidioidomycosis is a systemic infection caused by the soil-dwelling dimorphic fungi Coccidioides spp. The disease is endemic in semiarid Northeast Brazil, where it is caused by C. posadasii. The aim of this study was to perform antifungal susceptibility tests of clinical and environmental strains of C. posadasii from Northeast Brazil. The in vitro activities of caspofungin, amphotericin B and azoles against clinical and environment isolates of C. posadasii were determined in accordance with the NCLLS M-38P macrodilution method. The antifungal susceptibility analysis showed that all the strains of C. posadasii (n = 10) were sensitive to caspofungin (16 microg/ml < or = MIC < or = 32 microg/ml), amphotericin B (0.0625 mug/ml < or = MIC < or = 0.125 microg/ml), ketoconazole (0.039 microg/ml < or = MIC < or = 0.156 microg/ml), itraconazole (0.125 microg/ml < or = MIC < or = 0.5 microg/ml), fluconazole (3.125 microg/ml < or = MIC < or = 6.25 microg/ml), and voriconazole (0.125 microg/ml). This study is the first description of in vitro antifungal susceptibility pattern of Brazilian strains of C. posadasii.

    We examined associations between adverse childhood experiences (ACEs) and shorter telomere length (TL) in 83 older women, including 42 women with less than secondary education and 41 with secondary or more education in a city of Northeast Brazil, a region with substantial socioeconomic inequalities. The low education sample was selected from a representative survey at local neighborhood health centers, while the high education group consisted of a convenience sample recruited by advertising in community centers and centers affiliated with the local university. Relative leukocyte TL was measured by quantitative polymerase chain reaction from blood samples. ACEs were self-reported. Spline linear regression was fitted to assess the strength of the associations between ACEs and TL. Among women with low education, median TL was 1.02 compared with 0.64 in the high education group (p = 0.0001). Natural log-transformed T/S ratio as the dependent variable was used in analysis. Women with low education had been exposed to more ACEs, and among them those experiencing two or more ACEs had longer TL than women exposed to ≤1 ACEs (p = 0.03); among women with high education, this difference was not significant (p = 0.49). In analyses adjusted by age, education, and parental abuse of alcohol, the linear trend of higher TL with increasing ACEs was confirmed (p = 0.02), and the mean difference in TL between groups remained significant (p = 0.002). The unexpected positive relationship between low education and ACEs with TL suggests that older adults who have survived harsh conditions prevailing in Northeast Brazil have the longest TL of their birth cohort.

    2014-04-01

    Full Text Available The majority of research in mathematics education in Brazil focuses on aspects related to urban schools. Although there has been a discussion for decades about the need for a curriculum in schools located in rural areas that considers the importance of the local culture and the concept of context-based knowledge, there is still precarious teaching of mathematics in these schools. This paper discusses research data that addresses the teaching of mathematics in rural schools located in Pernambuco, Brazil. The method used is a qualitative research method based on interviews and discourse analysis. We focus on the discourse of teachers who participated in the empirical study by analyzing their views on rural education, the conceptualization of resources, and on their performance in mathematics teaching. Although most teachers positively evaluate their performance when they teach mathematics, they do not identify differences between teaching in the city and in rural areas. Generally, the teachers were unaware of the field schools' specificities. The results lead us to reflect on the possibilities of teaching mathematics to empower rural communities.

    The aim of this study was to characterize the profile of community health workers in northeastern Brazil and aspects related to the management of their work. This is a cross-sectional study, which included 535 community agents who were distributed in 107 primary health units in northeastern Brazil. The data were extracted from eight blocks of questions related to the community agents' perceptions about social-demographic, economic and political factors; their contracts and remuneration; their evaluation as workers; their working conditions and their training. The results indicate that the majority of community agents in the northeast region were hired by direct administration. The main form of hiring community agents was by public exam, followed by public selection. Direct administration is the main form of hiring; however, new modalities, such as the public and private law foundations, social organizations, and inter-municipal consortiums are alternatives that have been adopted by managers which can produce a number of weaknesses due to flexible labor relations.

    Biomasses created from natural resources such as firewood, charcoal and forest crops are still the main source of energy in many communities in the developing countries of the world. The absence of modern techniques, in terms of energy conversion and the lack of resource planning, places a great burden on the environment, not only in terms of deforestation but the polluting residual emissions created by the burning of such fuels. Even in some developed countries, it is possible to find rural areas that have no access to the conventional national electrical grid. The lack of this facility is detrimental to the social and economic development of any country or community. Renewable energy systems have been used in many cases to mitigate these problems. The present paper introduces the concept of an alternative Hybrid Power System configuration that combines photovoltaic modules and digesters fuelled by goat manure as the basis for rural sustainable development. Attention is drawn to the Northeast Region of Brazil, one of the largest semi-arid regions in a single country. The regional conditions of Northeast of Brazil are not unique, suggesting that other countries of a similar nature would benefit from the same energy system.

    2011-12-01

    This anthropological study from February 2009 to November 2010 revealed the comprehension and cultural critique of three mass media health campaigns in Northeast Brazil. Twenty-four ethnographic interviews were conducted, exploring the iconographic and semantic content of the campaigns in the Dendê community in Fortaleza, Ceará State, Brazil. The authors used Content Analysis; Systems of Signs, Significance, and Actions; and Contextualized Semantic Interpretation. There is a gap between the elaboration and reception of messages. Multiple interpretations occur (proximal reading, kaleidoscope of comprehension, and distant reading), depending on the reader's cognitive proximity to (or detachment from) the message. This "perceptual plasticity" arises from the creativity of popular imagination. Health professionals who hear rather than dismiss the "recipient's" subjective voice, which re-signifies authoritative messages, can penetrate the perception of the recipient's "visual world". In the context of poverty, this re-framing is essential for people to comprehend and proactively defend their own health.

    Human beings are the main reservoir of the causative agent of leprosy, Mycobacterium leprae. In the Americas, nine-banded armadillos (Dasypus novemcinctus) also act as a reservoir for the bacillus. In the state of Ceará (CE), which is located in Northeast Brazil and is an endemic area of leprosy, there are several species of armadillos, including D. novemcinctus and Euphractus sexcinctus (six-banded armadillo). Contact between humans and armadillos occur mainly through hunting, cleaning, preparing, cooking and eating. This study identified M. leprae DNA in the two main species of armadillos found in Northeast Brazil. A total of 29 wild armadillos (27 D. novemcinctus and 2 E. sexcinctus) were captured in different environments of CE countryside. Samples from the ear, nose, liver and spleen from each of these animals were tested by a nested M. leprae-specific repetitive element polymerase chain reaction assay. The samples that tested positive were confirmed by DNA sequencing. M. leprae was detected in 21% (6/29) of the animals, including five D. novemcinctus and one E. sexcinctus. This is the first Brazilian study to identify the presence of a biomarker of M. leprae in wild armadillos (D. novemcinctus and E. sexcinctus) in a leprosy hyperendemic area where there is continuous contact between humans and armadillos.

    Full Text Available The isolation of vancomycin resistant enterococci (VRE in Brazil has rapidly increased, following the world wide tendency. We report in the present study the first isolation of vancomycin resistant Enterococcus faecalis (VRE in the Northeast of Brazil. The four VRE isolates were characterized for antimicrobial susceptibility, genotypic typing by macro restriction of chromosomal DNA followed by pulsed-field gel electrophoresis and for characterization of the Tn1546-like element and plasmid contents. The isolates showed resistance to multiple antibiotics and a single genotype profile, suggesting the dissemination of a single clone among the patients. Tn1546 associated to genetic elements as plasmids shows the importance of infection control measures to avoid the spreading of glycopetide resistance by conjugative transfer of VanA elements.

    Equine infectious anemia virus (EIAV) is an important cause of morbidity and mortality throughout the world. Although the virus infects all members of the Equidae the vast majority of studies have been conducted in horses (Equus caballus) with comparatively little information available for other equid species. Brazil has one of the most abundant donkey (E. asinus) populations of any nation although the economic importance of these animals is declining as transportation becomes increasingly mechanized. As a result, considerable numbers of donkeys especially in the Northeast of the country have been released and allowed pursue an almost feral existence. Consequently, this large and growing population constitutes a significant risk as a reservoir for the maintenance and transmission of important equine infectious diseases such as glanders and equine arteritis virus in addition to EIAV. This study examines the prevalence of EIA in a semi-wild donkey population from Mossoró city, in Northeast Brazil, using AGID followed by cELISA, rgp90 ELISA and immunoblot (IB). Serum samples were collected from 367 donkeys without obvious EIA clinical signs. Subsequent testing revealed seropositive rates of 1.6% (6/367) in officially approved AGID tests, 3.3% (12/367) in cELISA and 14.4% (53/367) in the rgp90 ELISA. However, 88.7% (47/53) of the rgp90 ELISA positive samples were almost certainly false reactions because they failed to react with two or more antigens in IB. Consequently, the rpg90 ELISA has a similar sensitivity to AGID with donkey serum samples. Such high false positive rates have not been observed previously with serum samples from horses. Another highly significant finding is that 56.9% (33/58) of the donkey serum samples tested in IB had reactivity to EIAV p26 only. Although this could result from recent infection with the virus, it has been found that in some equids p26 only reactivity persists for extensive periods of time suggesting exposure to antigens

    The water balance of an artificial reservoir in the northeast of Brazil is derived by using the variations of oxygen isotopes and chlorine contents. With these two methods, the water losses through subsurface outflow are estimated at 20-40%. A more accurate evaluation would require an investigation of the variability of the relative humidity of the atmosphere. (author)

    Rabies is an endemic disease in Brazil, where it is considered a serious public health problem. Although the number of human and dog-transmitted cases has declined in recent decades, rabies in wildlife has emerged considerably. Among the sylvatic animals, wild canids have been considered important hosts of the rabies virus. We performed a retrospective study of reported cases of rabies in wild canids and human victims in Ceará state (Northeast Brazil) during 2003 to 2013. Information was provided by governmental laboratories involved in rabies detection and by the Ministry of Health. From January 2003 to December 2013, a total of 11 931 animal samples were examined for rabies. Positivity were detected in 438 samples (3.67%), of which 229 (52.28%) were domestic animals, 105 (23.97%) wild canids and 104 (23.74%) other wild animals (bats, marmosets and raccoons). Approximately 33% of wild canids surveyed (n = 317) were positive for rabies. During the studied period, a total of 1923 attacks on humans by wild canids were registered. Males (n = 1405) were more affected than females (n = 520; 72.98% versus 27.01%), and the median age of all cases was 36.5 years. Injuries to individuals up to 19 years old corresponded to approximately 30% (n = 565) of all cases. Most of the victims lived in rural areas (72.46%; n = 1395), and the majority showed bites (81.13%; n = 1677) or scratches (12.23%; n = 253). Injuries were considered profound (52.1%; n = 1003), superficial (40.91; n = 788) or multiple with severe laceration (6.98%; n = 134). Only 1300 (67.53%) victims were enrolled for the complete rabies post-exposure prophylaxis scheme. Data from the present study confirm that wild canids are important hosts of rabies virus in northeastern Brazil and jeopardize rabies control in this area. Local authorities should focus their efforts in education of health professionals. In addition, strategies should be formulated to preserve wildlife. © 2016 Blackwell

    Coccidioidomycosis is an endemic infection in the Americas caused by the dimorphic fungi Coccidioides immitis and Coccidioides posadasii. Although the disease occurs in Brazil in sporadic form, little information about these cases is available. In this study, we summarize the most important clinical, epidemiologic, and diagnostic features of coccidioidomycosis in Ceará State (Northeast Brazil) during the past 12 years. In this period, 19 cases of coccidioidomycosis were diagnosed. All the patients were young males and came from semiarid areas of the state. The majority of cases were associated to armadillo hunting, and pulmonary disease was the most common clinical presentation. In our laboratory, coccidioidomycosis was confirmed by culture, serology, and polymerase chain reaction tests, which together were very suitable for the diagnosis of this disease. Based on our local experience, we believe many cases of this disease are misdiagnosed or not diagnosed in our region. Therefore, some strategies for improvement of diagnosis should be encouraged by local authorities.

    Large scale circulation features are presented as related to wet spells over northeast Brazil (Nordeste) during the rainy season (March and April) of 1979. The rainy season season is devided into dry and wet periods, the FGGE and geostationary satellite data was averaged and mean and departure fields of basic variables and cloudiness were studied. Analysis of seasonal mean circulation features show: lowest sea level easterlies beneath upper level westerlies; weak meridional winds; high relative humidity over the Amazon basin and relatively dry conditions over the South Atlantic Ocean. A fluctuation was found in the large scale circulation features on time scales of a few weeks or so over Nordeste and the South Atlantic sector. Even the subtropical High SLP's have large departures during wet episodes, implying a short period oscillation in the Southern Hemisphere Hadley circulation.

    Full Text Available The Atlantic Forest of northeast Brazil hosts a unique biota which is among the most threatened in the Neotropics. Near-total conversion of forest habitat to sugar cane monocultures has left the region's endemic forest-dependent avifauna marooned in a few highly-fragmented and degraded forest remnants. Here we summarise the current status of 16 globally threatened species based on surveys conducted over the last 11 years. We found a bleak situation for most of these species and consider that three endemics: Glaucidium mooreorum (Pernambuco Pygmy-owl, Cichlocolaptes mazarbarnetti (Cryptic Treehunter and Philydor novaesi (Alagoas Foliage-gleaner are most likely globally extinct. Some positive news can, however, be reported for both Leptodon forbesi (White-collared Kite and Synallaxis infuscata (Pinto's Spinetail which may warrant re-evaluation of their respective red list statuses. We outline a road map to prioritise conservation interventions in the region directed at preventing the extinction of this suite of threatened bird species and their companion biota.

    Full Text Available This work examines the teaching method of Paulo Freire implemented in Jaguaquara Rural School, Escola Estadual Rural Taylor-Egídio (ERTE, Brazil. The school was the space where dialogical pedagogy has been analyzed and the dialogue between schools and rural households has been a positive and winning response in the children’s literacy process. This research has shown that, before Freire, rural families had not had an education system able to meet their need; then the study has taken into account some factors responsible for this lack; finally, it has singled out the possibility for an effective implementation in the rural school, according to Freire’s model of dialogic pedagogy. The results of this school experience are relevant from the point of view of socialization, for it fosters literacy in rural areas. We verified that the method proposed by Freire is of great social and cultural value and benefits from great appreciation.

    Full Text Available AbstractIn search for renewable energy sources, the Brazilian residual biomasses stand out due to their favorable physical and chemical properties, low cost, and their being less pollutant. Therefore, they are likely to be used in biorefineries in the production of chemical inputs to substitute fossil fuels. This substitution is possible due to the high contents of carbohydrates (>40%, low contents of extractives (<20%, ashes (<8% and moisture (<8% found in these residual biomasses. High calorific values of all residues also offer them the chance to be used in combustion. A principal components analysis (PCA was performed for better understanding of the samples and their hysic-chemical properties. Thus, this study aimed to characterize biomasses from the north (babassu residues, such as mesocarp and endocarp; pequi and Brazil nut and northeast (agave and coconut regions of Brazil, in order to contribute to the preservation of the environment and strengthen the economy of the region.

    The oyster Crassostrea gasar is a species widely used as food and a source of income for the local population of the estuaries of Northeast Brazil. Perkinsus marinus and Perkinsus olseni are deleterious parasites for oyster farming and were recently detected in Brazil. In this study, a histopathologic survey of the oyster C. gasar cultured in the estuary of the River Mamanguape (Paraíba State) was performed. Adult oysters were collected in December 2011 and March, May, August and October 2012 and processed for histology and Perkinsus sp. identification by molecular analyses. Histopathological analysis revealed the presence of parasitic organisms including viral gametocytic hypertrophy, prokaryote-like colonies, protozoans (Perkinsus sp. and Nematopsis sp.) and metazoans (Tylocephalum sp. and cestodes). Other commensal organisms were also detected (the protozoan Ancistrocoma sp. and the turbellarian Urastoma sp.). The protozoan parasite Perkinsus sp. had the highest overall prevalence among the symbiotic organisms studied (48.9%), followed by Nematopsis sp. (36.3%). The other organisms were only sporadically observed. Only the protozoan Perkinsus sp. caused alterations in the oysters' infected organs. Molecular analyses confirmed the presence of P. marinus, P. olseni and Perkinsus beihaiensis infecting the oyster C. gasar. This is the first report of P. beihaiensis in this oyster species.

    Full Text Available Agroforestry systems (AFS are considered alternative land use options to help prevent soil degradation and improve soil microbial biomass and organic C status. However, it is unclear how different densities of babassu palm [Attalea speciosa (syn. Orbignya phalerata], which is an important tree in Northeast Brazil, affect the soil microbial biomass. We investigated the soil microbial biomass C and activity under AFS with different densities of babassu palm associated with Brachiaria brizantha grass. Soil microbial biomass C (MBC, soil microbial biomass N (MBN, MBC:total organic C ratio, fluorescein diacetate hydrolysis and dehydrogenase activity showed highest values in plots with high density of babassu palm. On the other hand, the respiratory quotient (qCO2 was significantly greater in plots without babassu palm. Brachiaria brizantha in monoculture may promote C losses from the soil, but AFS with high density of babassu palm may increase the potential of soils to accumulate C.Keywords: Enzyme activity, tropical soil, babassu palm, silvopastoral system, soil quality.DOI: 10.17138/TGFT(341-48

Between 2011 and 2013, 110 field trips were performed in nine reserves in the domain of the Atlantic Rain Forest. Two thousand two hundred sixty three Agaricomycetes were collected and represented 271 species, among which several new species to science, new occurrences to the continent, country, region, biome and States were found. Besides recently collected material, 309 exsiccates of Agaricomycetes deposited in the Herbarium URM were revised and represented 38 species, among which several new occurrences to the region and States. The results indicate the importance of the constant inventories and also of revisions of material deposited in herbaria as tools to improve the knowledge about the Brazilian micota.

    To assess the prevalence of pregnancy complications identified as maternal near miss (MNM) and associated factors among women using the public health care system in the Amazon and Northeast regions of Brazil. A secondary analysis of a population-based survey conducted in 2010 was performed focusing on women self-reporting maternal complications. The main outcome was MNM, pragmatically defined as intensive care unit admission, eclampsia, hysterectomy, or blood transfusion. In addition, the risk of MNM was estimated for certain sociodemographics and characteristics of care received. Poisson regression was performed, generating adjusted prevalence ratios (PRadj) with 95% confidence intervals (95%CI). A total of 13 044 women (77%) who had given birth during the prior year using the public health system were interviewed. At least one complication was reported by 37.5%, with hemorrhage (28.4%) and infection (8.3%) being the most frequent. The overall MNM ratio was 31.5 per 1 000 live births, higher for the Amazon region than for the Northeast. Factors with a higher risk for developing MNM were: indigenous ethnicity (PRadj 2.77; 95% CI: 1.50-5.14), more than one hour to reach the hospital (PRadj 1.55; 95%CI: 1.06-2.25), being refused by a full hospital and having to find another one (PRadj 1.49; 95%CI: 1.03-2.16), cesarean section (PRadj 2.56; 95%CI: 1.90-3.44), and public prenatal care (PRadj 1.95; 95%CI: 1.06-3.61). Users of public health system in the Amazon and Northeast regions of Brazil have high MNM rates. Some characteristics of the women and of the care they received represent inequalities associated with higher risk for MNM. Specific actions are required to improve maternal health programs in these expansive areas of the country.

    Epidemiological literature on occupational accidents among rural workers is scarce in Brazil. This population-based cross-sectional study was designed to investigate the characteristics of farming accidents occurring in the rural area of Pelotas, Southern Brazil. A multi-stage sampling scheme was used to select a representative sample of farms. From January to April 1996, a total of 258 rural families were visited, and all 580 rural workers identified in these families answered a standardized questionnaire. Sixty-three rural workers (11%) reported at least one work-related accident in the previous twelve months. There were 82 accidents during the study period, mainly related to the use of hand farm tools (29%) and handling farm animals (27%). The main types of injuries were cuts (50%), bruises (13%), and burns (9%). The body areas most frequently involved were hands (34%), feet (29%), and legs (18%). Among the injured rural workers, only 32% used health services to treat the resulting lesions (46% went to primary health care facilities and 36% to emergency services).

    In Brazil and particularly in the Northeast of Brazil, illuminance measures are not part of routine meteorological station measures, and therefore they are still rare than solar irradiation measures. In this context, two stations were installed in Pernambuco: one in Recife (maritime tropical climate) in April 2003 and the other in Pesqueira (tropical and semi-arid) in September 2004 for carrying out simultaneous measurements of hourly solar irradiation and illuminance which permit the modeling and the statistic validation of the relationship between these two parameters and with this, makes possible the estimation of illuminance where there existed only information on solar irradiation. The Alados et al. model with local coefficients showed a superior statistical performance, producing a mean bias deviation in the order of 3% and 1% and root mean quadratic deviation of 10% and 3% respectively for Recife and Pesqueira (author)

    The significant increase in recent years of the number of rural electrification systems (some thousands of them do exist) using photovoltaic technology installed in the Northeast of Brazil (1,500,000 km{sup 2}, approximately 42 million people) used for illumination or water pumping, calls for an improvement on the design procedures in order to reduce the burden of capital costs per unit of generated power. Such objective can be accomplished as long as a better knowledge about the solar resource is achieved, considering how much these applications depend on it. The sources of information on solar radiation in Brazil are quite varied at both institutional and publication level. At institutional Meteorology (INMET), State Departments of Agriculture, research institute, universities and electric power generation and distribution utilities. Progress reports or scientific and technical journals are the main publishing vehicles where this information can be found. This way, data quality varies considerably, showing, spatial and temporal discontinuities, in addition to the fact that measurement instruments and physical units of registered data are not standardized. The Solarimetric Atlas of Brazil was recently published and it contains that information, which is grouped, evaluated, qualified, and presented in a standardized way. It is one of the best currently existing sources of information, and in certainly consists of almost the entirety of the existing information on the solar resource (data on solar radiation and sunshine hours) in Brazil. By using this database, simultaneous records of solar radiation (measured with pyranoghaps or pyranometers) and sunshine hours with heliographs were obtained in 35 different places in the Northeast region. Coefficients a and b were calculated for those different places using Angstrom's correlation. Using the geostatistical interpolation method known as kriging, the values of a and b were placed on contour maps, the coverage of

    The 2012 drought in Northeast Brazil was the harshest in decades, with potentially significant impacts on the vegetation of the unique semi-arid caatinga biome and on local livelihoods. Here, we use a coupled climate–vegetation model (CCM3-IBIS) to: (1) investigate the role of the Pacific and Atlantic oceans in the 2012 drought, and; (2) evaluate the response of the caatinga vegetation to the 2012 climate extreme. Our results indicate that anomalous sea surface temperatures (SSTs) in the Atlantic Ocean were the primary factor forcing the 2012 drought, with Pacific Ocean SST having a larger role in sustaining typical climatic conditions in the region. The drought strongly influenced net primary production in the caatinga, causing a reduction in annual net ecosystem exchange indicating a reduction in amount of CO 2 released to the atmosphere.

    Full Text Available ABSTRACT We studied the population structure and fruit availability of the babassu palm, Attalea speciosa, in three human-dominated landscapes located near a rural community in the region of Araripe, in the Northeast Region of Brazil, that were under intense fruit harvest. Fifty 10 x 10 m plots were randomly established in each of the three landscapes, and all individuals of A. speciosa within the plots were classified as seedlings, juveniles or adults, with the height of all adult individuals being measured. An additional 20 individuals were marked in each landscape, and the number of total bunches, fruits per bunch and bunches per palm tree were recorded. The populations of A. speciosa in the three landscapes exhibited an inverted J-shape plot, but pasture and shifting cultivation possessed a significantly higher number of individuals, seedlings and adults than the seasonal semideciduous forest, plus they possessed a greater seedling/adult ratio. Shifting cultivation was found to be favorable for fructification. The present study found that shifting cultivation and pastures are landscape practices that can contribute to the rapid expansion and establishment of A. speciosa, which can become a dominant species in the region of Araripe.

    Starting in August 2015, there was an increase in the number of cases of neonatal microcephaly in Northeast Brazil. These findings were identified as being an epidemic of microcephaly related to Zika virus (ZIKV) infection. The present study aims to analyse the spatial distribution of microcephaly cases in Recife (2015-2016), which is in Northeast Brazil, and its association with the living conditions in this city. This was an ecological study that used data from reported cases of microcephaly from the State Health Department of Pernambuco (August 2015 to July 2016). The basic spatial unit of analysis was the 94 districts of Recife. The case definition of microcephaly was: neonates with a head circumference of less than the cut-off point of -2 standard deviations below the mean value from the established Fenton growth curve. As an indicator of the living conditions of the 94 districts, the percentage of heads of households with an income of less than twice the minimum wage was calculated. The districts were classified into four homogeneous strata using the K-means clustering algorithm. We plotted the locations of each microcephaly case over a layer of living conditions. During the study period, 347 microcephaly cases were reported, of which 142 (40.9%) fulfilled the definition of a microcephaly case. Stratification of the 94 districts resulted in the identification of four strata. The highest stratum in relation to the living conditions presented the lowest prevalence rate of microcephaly, and the overall difference between this rate and the rates of the other strata was statistically significant. The results of the Kruskal-Wallis test demonstrated that there was a strong association between a higher prevalence of microcephaly and poor living conditions. After the first 6 months of the study period, there were no microcephaly cases recorded within the population living in the richest socio-economic strata. This study showed that those residing in areas with

    Full Text Available Food insecurity occurs when the unmet nutritional needs cause psychological and physiological problems. Thinking about this panorama, this cross-sectional study aimed to evaluate the relationship between food insecurity and overweight in the Northeast and South. We used a form to identify the socioeconomic and demographic variables, was also made the calculation of BMI, and applied the Brazilian Scale of Food and Nutritional Insecurity in two regions of Brazil where 807 people were interviewed and 503 in the Northeast region and 304 in the South region. The most prevalent share of family income in both regions was that between ½ to 1 minimum wage. The Northeast region had a higher prevalence of users in food insecurity over the southern region, also presented more socioeconomic differences as lower education and income per capita, a higher proportion of unemployed and users in Food Insecurity in relation to the South. This fact is explained by population have a higher proportion of unemployed and a lower per capita income, leading to reduced power of access to food. Regarding nutritional status, in both regions there was overweight. This data may be indicative of the accelerated process of nutritional transition that lives the Brazilian population.

    This paper analyzes the evolution of five electricity distribution companies in the Northeast of Brazil using technical and financial indicators. Three privatized and two public firms were analyzed between 1997 and 2008. The financial indicators are used as proxies for the capacity of the business to generate value for shareholders, while the technical indicators are used as proxies for service quality provided to consumers. We observed that the privatized firms had their financial indicators improved after privatization, increasing the value of the firm for the shareholders. However, there is no evidence that privatization affected the quality of service provided to consumers. (author)

    Field observations carried in semi-arid Brazil Northeast point out the frequent association, in the peridomiciliary space, between a cactus, Cereus jamacaru, the occurrence of nests in its branches and the occurrence of two species of insects vectors of Trypanosoma cruzi, pathogenic agent of Chagas disease: Rhodnius neglectus and Triatoma pseudomaculata. The analysis of the architectural variables of this Cactaceae shows that the presence of nests, and thus of insects, depends on the traditional practices of management of this cactus. This study underlines the relevance of an integrated approach of the ecology of Triatominae for the identification of factors of risk.

    Transmission of Zika virus (ZIKV) in the Americas was first confirmed in May 2015 in northeast Brazil. Brazil has had the highest number of reported ZIKV cases worldwide (more than 200,000 by 24 December 2016) and the most cases associated with microcephaly and other birth defects (2,366 confirmed by 31 December 2016). Since the initial detection of ZIKV in Brazil, more than 45 countries in the Americas have reported local ZIKV transmission, with 24 of these reporting severe ZIKV-associated disease. However, the origin and epidemic history of ZIKV in Brazil and the Americas remain poorly understood, despite the value of this information for interpreting observed trends in reported microcephaly. Here we address this issue by generating 54 complete or partial ZIKV genomes, mostly from Brazil, and reporting data generated by a mobile genomics laboratory that travelled across northeast Brazil in 2016. One sequence represents the earliest confirmed ZIKV infection in Brazil. Analyses of viral genomes with ecological and epidemiological data yield an estimate that ZIKV was present in northeast Brazil by February 2014 and is likely to have disseminated from there, nationally and internationally, before the first detection of ZIKV in the Americas. Estimated dates for the international spread of ZIKV from Brazil indicate the duration of pre-detection cryptic transmission in recipient regions. The role of northeast Brazil in the establishment of ZIKV in the Americas is further supported by geographic analysis of ZIKV transmission potential and by estimates of the basic reproduction number of the virus.

    This study aims to describe the prices of food groups consumed in Brazil considering the nature, extent, and purpose of their processing. Data were obtained from the Brazilian Household Budget Survey for 2008-2009. The mean prices of the groups (natural, cooking ingredients, processed, and ultra-processed) and their respective food subgroups were estimated for Brazil according to income, region, and area. Natural products and cooking ingredients showed lower prices per calorie when compared to the other groups, suggesting an economic advantage to preparing meals at home when compared to replacing them with ultra-processed foods. Families with the highest income paid the highest prices for their food, while families in the Northeast and North regions and rural areas paid the lowest. While fresh foods (meat, milk, fruit, and vegetables) tend to cost more than ultra-processed foods, dry grains (like rice and beans) are a more economical alternative for adopting healthy eating practices.

    Our latest study reported the grim status of hypertension in rural China with the prevalence of hypertension reached 51.1%. However, we lack the latest data about the prevalence and epidemiological features of dyslipidemia among hypertensive residents in rural China. A cross-sectional survey was conducted from July 2012 to August 2013 through a cluster multistage sampling to a resident group of 4048 individuals (2152 men, 2896 women) with hypertension, age ≥ 35 years, in the rural Northeast China. Serum lipids level were proposed by National Cholesterol Education Program Adult Treatment Panel III. Of the hypertension residents without antihypertension treatment, 34.5% had borderline high total cholesterol, 19.2% had high total cholesterol, 11.4% had low high-density lipoprotein cholesterol and 37.4% had high non HDL-C. The population with borderline high, high, and very high low-density lipoprotein cholesterol was 20.9, 6.7 and 2.3%, respectively. In addition, 14.3% had borderline high triglycerides, 17.4% had high TG and 2.4% had very high TG. The awareness rate of dyslipidemia among the study population was 5.9%. After adjusting for independent variables, fasting plasma glucose, body mass index, Han nationality, current drinking and smoking, higher annual income and classification of blood pressure were risk factors for dyslipidemia while moderate physical activity was protective factor for dyslipidemia. On the contrary, gender and current drinking decrease the risk of HDL-C. The prevalence of dyslipidemia was dramatically high and dyslipidemia screening was in-need in all diagnosed hypertensive individuals.

    Full Text Available This study aimed to comprehensively compare the general characteristics, lifestyles, serum parameters, ultrasonic cardiogram (UCG parameters, depression, quality of life, and various comorbidities between empty nest and non-empty nest elderly among rural populations in northeast China. This analysis was based on our previous study which was conducted from January 2012 to August 2013, using a multistage, stratified, random cluster sampling scheme. The final analyzed sample consisted of 3208 participants aged no less than 60 years, which was further classified into three groups: non-empty nest group, empty nest group (living as a couple, and empty nest group (living alone. More than half of the participants were empty nest elderly (60.5%. There were no significant statistical differences for serum parameters, UCG parameters, lifestyles, dietary pattern, and scores of Patient Health Questionnaire-9 (PHQ-9 and World Health Organization Quality of Life questionnaire, abbreviated version (WHOQOL-BREF among the three groups. Empty nest elderly showed no more risk for comorbidities such as general obesity, abdominal obesity, hyperuricemia, hyperhomocysteinemia, diabetes, dyslipidemia, left atrial enlargement (LAE, and stroke. Our study indicated that empty nest elderly showed no more risk for depression, low quality of life and comorbidities such as general obesity, abdominal obesity, hyperuricemia, hyperhomocysteinemia, diabetes, dyslipidemia, LAE, and stroke among rural populations in northeast China.

    Full Text Available SUMMARY Chagas disease is caused by Trypanosoma cruzi and affects about two to three million people in Brazil, still figuring as an important public health problem. A study was conducted in a rural area of the municipality of Limoeiro do Norte - CE, northeastern Brazil, aiming to determine the prevalence of T. cruzi infection. Of the inhabitants, 52% were examined, among whom 2.6% (4/154 were seropositive in at least two serological tests. All seropositive individuals were older than 50 years, farmers, with a low education and a family income of less than three minimum wages. Active surveillance may be an alternative for early detection of this disease.

    Objective: The burden of noncommunicable diseases (NCDs) is increasing in China, together with economic development and social changes. The prevalence of risk factors for NCDs, such as overweight/obesity, hypertension, diabetes, and dyslipidemia, is reported to be high even among poor residents of rural areas. We aimed to investigate the prevalence of hypertension among elderly adults in rural Northeast China and the proportion with controlled hypertension among those on antihypertensive medication (hypertension control rate). We also aimed to examine the association of hypertension control with health facilities that provide treatment. Methods: We conducted a community-based cross-sectional study in six rural villages of Northeast China from February to early March, 2012. We interviewed 1593 adults aged 50-69 years and measured their blood pressure. We examined the differences in mean blood pressure between participants who obtained antihypertensive medication from village clinics and those who obtained medication from other sources, using analysis of covariance adjusted for several covariates. Results: The prevalence of hypertension among participants was as high as 63.3%, but the hypertension control rate was only 8.4%. Most villagers (98.1%) were not registered in the chronic disease treatment scheme of the public rural health insurance. The mean systolic blood pressure, adjusted for the covariates, of participants who obtained antihypertensive medication from village clinics was significantly lower than that of participants who obtained medication from township hospitals (by 16.5 mmHg) or from private pharmacies (by 7.3 mmHg). Conclusion: The prevalence of hypertension was high and the hypertension control rate low among elderly villagers during the cold season. As treatment at village clinics, which villagers can access during the cold season seems to be more effective than self-medication or treatment at distant hospitals, improving the quality of treatment

    Full Text Available Drought is a natural and physical phenomenon that occurs with some regularity in the Northeast of Brazil. The reductionist understanding of this problem, associated with lack of water, facilitates the naturalization of its social effects. The article aims to discuss the psychosocial impacts of the drought in the lives of residents of a rural community in northeastern Brazil. The methodology is quantitative, with the provision of a questionnaire to 207 subjects, residents of Canafístula Community, city of the State of Ceará. It was learned that 87.9 % of participants had lived through some drought, which impacted on the lack of water for human and animal consumption, in production losses. Insecurity about the future, feelings of discouragement and sadness, fatalism and acquired hopelessness appear as psychosocial impacts of the drought. It highlights the importance of denaturalization of this phenomenon and the analysis of the objective and subjective impacts on the lives of rural communities

    HIV-1 transmitted-drug-resistance and genetic diversity are dynamic and may differ in distinct locations/risk groups. In Brazil, increased AIDS incidence and related mortality have been detected in the Northeast region, differently from the epicenter in the Southeast. This cross-sectional study describes transmitted-dru- resistance and HIV-1 subtypes in protease/PR and reverse transcriptase/RT regions among antiretroviral naïve patients from Piauí State, Northeast Brazil. Among 96 patients recruited 89 (92.7%) had HIV-1 PR/RT regions sequenced: 44 females and 45 males, 22 self-declared as men who have sex with men. Transmitted-drug-resistance was investigated by CPR tool (Stanford HIV-1 Drug Resistance/SDRM). HIV-1 subtypes were assigned by REGA and phylogenetic inference. Overall, transmitted-drug-resistance rate was 11.2% (10/89; CI 95%: 5.8-19.1%); 22.7% among men who have sex with men (5/22; CI 95%: 8.8-43.4%), 10% in heterosexual men (2/20; CI 95%: 1.7-29.3%) and 6.8% in women (3/44; CI 95%: 1.8-17.4%). Singleton mutations to protease-inhibitor/PI, nucleoside-reverse-transcriptase-inhibitor/NRTI or non-nucleoside-reverse-transcriptase-inhibitor/NNRTI predominated (8/10): PI mutations (M46L, V82F, L90M); NRTI mutations (M41L, D67N) and NNRTI mutations (K103N/S). Dual class resistance mutations to NRTI and NNRTI were observed: T215L (NRTI), Y188L (NNRTI) and T215N (NRTI), F227L (NNRTI). Subtype B prevailed (86.6%; 77/89), followed by subtype F1 (1.1%, 1/89) and subtype C (1.1%, 1/89). B/F1 and B/C intersubtype recombinants represented 11.2% (10/89). In Piauí State extensive testing of incidence and transmitted-drug-resistance in all populations with risk behaviors may help control AIDS epidemic locally. © 2015 Wiley Periodicals, Inc.

    Full Text Available The objective of this study was to characterize the population genetic structure of the Gir breed in the Northeast of Brazil. The data used in this study were taken from pedigree information of 8,897 Gir animals between 1957 and 2007, obtained from the Brazilian Zebu Breeders Association (ABCZ. The program ENDOG was used to estimate the parameters based on the probability gene origin. From the amount of the studied animals, 67.22%, 18.41% and 3.15% had complete pedigree only on the first, second and third parentage, respectively. The number of ancestors that contributed for the reference population was 2,755, of which only 171 explain the 50% genetic variability of the population. The actual number of founder herds was 168 and the effective number of founder herds was 22.3. The number of sire supplier herds was 22.16, 8.66 and 5.36 for fathers, grandfathers and great-grandfathers, respectively. The average coefficient of relatedness was estimated at 0.22%; the highest individual coefficient was 1.49%. The little variability of the current population is a result of the small number of effective founders and ancestors indicating the population evolved from a narrow genetic base.

    Full Text Available The present study investigated the distribution and abundance of epibenthic molluscs and their feeding habits associated to substrate features (coverage and rugosity in a sandstone reef system in the Northeast of Brazil. Rugosity, low coral cover and high coverage of zoanthids and fleshy alga were the variables that influenced a low richness and high abundance of a few molluscan species in the reef habitat. The most abundant species were generalist carnivores, probably associated to a lesser offer and variability of resources in this type of reef system, when compared to the coral reefs. The results found in this study could reflect a normal characteristic of the molluscan community distribution in sandstone reefs, with low coral cover, or could indicate a degradation state of this habitat if it is compared to coral reefs, once that the significantly high coverage of fleshy alga has been recognized as a negative indicator of reef ecosystems health.

    Full Text Available Abstract This study compared differences in degree of happiness, social support, activities performed, and health and economic situation among retirees from urban and rural areas in Minas Gerais State in Brazil. The influences of these predictors over individuals’ level of happiness were also analyzed. We included 279 retired individuals living in Abre Campo (a municipality with a population fewer than 20,000 inhabitants, which is considered a rural area and in Belo Horizonte (a municipality with a population of almost 2.5 million inhabitants, which is considered an urban area. Participants responded to a questionnaire that included scales of happiness, social support, diversity of activities, and issues about satisfaction with health and economic situation. Retirees from the urban area had a higher happiness level than retirees from the rural area (β= 0.16. The most important predictors of happiness were health (β= 0.42, social support (β= 0.26, and economic situation (β= 0.15, but no moderation effects of urban and rural areas were found. Our findings support the implementation of actions to offer financial planning before retirement and to stimulate social support and health promotion for retirees, particularly given the importance of these factors in perception of happiness.

    'Na prática, a teoria è outra' (in practice, the theory is different) is an old Brazilian saying. This phrase summarizes well the general practice of breastfeeding in Brazil: 'Breast is best' is central in the pregnant women's future oriented 'theory' of how their infant should be fed. In the subsequent weeks after delivery, however, in the daily practicalities of feeding their infant, this theory is, to a large extent, abandoned. The present study is based on a sample of 300 mothers in the city of Aracaju in the Northeast of Brazil. Through interviews, the differences and similarities between knowledge and practice with respect to infant feeding were established. An explanation of these differences is developed on the basis of a processual analysis of the qualitative and quantitative results of the interview data. Nearly all mothers were knowledgeable of the need to breastfeed, and nearly all mothers had initiated breastfeeding. However, only a minority was exclusively breastfeeding at the time of the interview. A distinction is made between a breastfeeding process and a de-breastfeeding process. The data suggest that mothers, in general, start the de-breastfeeding process with the positive intention of ameliorating the infant's situation without realizing the negative processual consequences that most likely ends in a cessation of breastfeeding. The study supports the view that health policy should underline the processual character of both breastfeeding and de-breastfeeding when promoting the importance of exclusive breastfeeding.

    Full Text Available The objective of this research was to analyze rainfall in the municipality of Cas- telo do Piauí, located in the Northeast of Brazil, based on descriptive statistics and the Rainfall Anomaly Index (RAI. From an historical series of 39 years (1963 to 2001, a historical average of 1006.3 mm was identi ed for this municipality, whereas the years 1985 and 1983 were considered the most and least rainy, re- spectively. The rainy season is concentrated in the months of January to April, with March being the wettest and August being the least rainy. Rainfall variability values were higher than 40% for all months and asymmetric positive distribution. The RAI allowed to establish the following dry and rainy years: 1963, 1964 and 1989 (very rainy; 1974 and 1985 (extremely rainy; 1976, 1981, 1992, 1993, 1998 and 2001 (very dry; 1983 and 1990 (extremely dry. In summary, the present study found a predominance of dry to extremely dry years in the studied area, with 53.8%.

    Pregnancy encompasses socio-cultural, historical, and affective dimensions that process various meanings in women's bodies. Each society constructs popular concepts, practices, and explanatory models that differ from the biomedical model and aim to protect the mother and fetus and foster a healthy pregnancy. This qualitative study, based on interpretative anthropology, unveils the experiences of 27 poor women and their repercussions on the malnutrition of their infants, treated at a Childhood Malnutrition Treatment Center in Fortaleza, Northeast Brazil. From January to June 2004, ethnographic and narrative interviews were conducted on so-called "birth weakness", in addition to participant observation of outpatient, nursing, and home childcare. The mothers believed that their own physical and emotional suffering and precarious nutritional status were "imprinted" on the fetus, resulting in the child's malnutrition. While the ethno-etiology of "weakness" points to factors outside the body that involuntarily affect the pregnant mother, the medical view tended to incriminate the mother herself. It is necessary to understand the mothers' narratives, sympathize with their suffering, and spawn a closer approach between the popular and biomedical concepts.

    This article analyzes the relations between mental health and well-being in urban and rural contexts marked by poverty. The analysis takes as its basis a quantitative research conducted with 417 adult inhabitants of two communities, one rural and the other urban, in Northeastern Brazil. The data were constructed using questionnaires composed of sociodemographic data, the Personal Wellbeing Index and Self Report Questionnaire (SRQ-20) scales. We found significant differences between the inhabitants of the rural and urban communities regarding well-being and the prevalence of common mental disorders (CMD), with a higher average well-being score in the rural context; the urban sample had a higher average regarding the prevalence of CMD. The variable income significantly influenced the SRQ-20 average scores; the same was not observed with well-being scores. Besides, it was observed that there is a negative correlation with well-being and CMD.

  13. Understanding the predictability of seasonal precipitation over northeast Brazil

    Using multiple long-term simulations of the Center for Ocean-Land-Atmosphere Studies (COLA) atmospheric general circulation model (AGCM) forced with observed sea surface temperature (SST), it is shown that the model has high skill in simulating the February-March-April (FMA) rainy season over northeast Brazil (Nordeste). Separate sensitivity experiments conducted with the same model that entails suppression of all variability except for the climatological annual cycle in SST over the Pacific and Atlantic Oceans reveal that this skill over Nordeste is sensitive to SST anomalies in the tropical Atlantic Ocean. However, the spatial pattern of SST anomalies in the tropical Atlantic Ocean that correlate with FMA Nordeste rainfall are in fact a manifestation of El Niño Southern Oscillation (ENSO) phenomenon in the Pacific Ocean. This study also analyzes the failure of the COLA AGCM in capturing the correct FMA precipitation anomalies over Nordeste in several years of the simulation. It is found that this failure occurs when the SST anomalies over the northern tropical Atlantic Ocean are large and not significantly correlated with contemporaneous SST anomalies over the eastern Pacific Ocean. In two of the relatively large ENSO years when the model failed to capture the correct signal of the interannual variability of precipitation over Nordeste, it was found that the meridional gradient of SST anomalies over the tropical Atlantic Ocean was inconsistent with the canonical development of ENSO. The analysis of the probabilistic skill of the model revealed that it has more skill in predicting flood years than drought. Furthermore, the model has no skill in predicting normal seasons. These model features are consistent with the model systematic errors.

    Full Text Available This study reports the influence of season on foraging activities and internal colonial parameters of Melipona asilvai in an Atlantic forest area of northeast Brazil. We used video cameras connected to a PC to monitor all departures and returns of foragers and the types of materials they carried. Foraging activities decreased almost 90% from dry to rainy seasons, but temperature and humidity were not the main factors influencing departures. Observed honey storage and an extreme cutback in activities during the rainy period suggest a seasonal diapause in this species.

    Circulatory system diseases are the first cause of death in Brazil. To analyze the evolution of mortality caused by heart failure, by ischemic heart diseases and by ill-defined causes, as well as their possible relations, in Brazil and in the geoeconomic regions of the country (North, Northeast, Center-West, South and Southeast), from 1996 to 2011. Data were obtained from DATASUS and death declaration records with codes I20 and I24 for acute ischemic diseases, I25 for chronic ischemic diseases, and I50 for heart failure, and codes in chapter XIII for ill-defined causes, according to geoeconomic regions of Brazil, from 1996 to 2011. Mortality rates due to heart failure declined in Brazil and its regions, except for the North and the Northeast. Mortality rates due to acute ischemic heart diseases increased in the North and Northeast regions, especially from 2005 on; they remained stable in the Center-West region; and decreased in the South and in the Southeast. Mortality due to chronic ischemic heart diseases decreased in Brazil and in the Center-West, South and Southeast regions, and had little variation in the North and in the Northeast. The highest mortality rates due to ill-defined causes occurred in the Northeast until 2005. Mortality due to heart failure is decreasing in Brazil and in all of its geoeconomic regions. The temporal evolution of mortality caused by ischemic heart diseases was similar to that of heart failure. The decreasing number of deaths due to ill-defined causes may represent the improvement in the quality of information about mortality in Brazil. The evolution of acute ischemic heart diseases ranged according to regions, being possibly confused with the differential evolution of ill-defined causes

    Full Text Available The aim of this study was to conduct a serological survey for Lyme diseases, brucellosis, leptospirosis and toxoplasmosis and identify the risk variables related to these zoonoses in humans living in the rural area of Jataizinho, state of Parana, Brazil. A total of 63 rural properties were surveyed. Additionally, 207 serum samples collected from these rural area inhabitants were tested for indirect immunofluorescence (IFI and western blots (WB were performed to detect Borrelia burgdorferi (sensu lato; a tamponated acidified antigen test (AAT and 2-mercaptoethanol (2-ME were used to detect antibodies of Brucella abortus; the microscopic agglutination test (MAT was carried out to detect antibodies anti-Leptospira spp. and IFI was used to find antibodies of Toxoplasma gondii. Two of the samples (0.96% were reactive for Lyme borreliosis, three (1.4% for brucellosis, 25 (12.1% for leptospirosis and 143 (69.1% for toxoplasmosis. Although the town of Jataizinho has a human development index (IDH that was considered to be average (0.733 in the state of Parana, the low social, economic and cultural conditions of the population from small rural properties have resulted in lack of basic information on animal health and direct or indirect contact with the various species of domestic animals, wildlife and ticks have probably contributed to the prevalence levels found. These results show the need for additional regional studies in order to determine the epidemiological characteristics of these diseases as well as their respective vectors and reservoirs so that effective prophylaxis can be administered in the human population.

    Full Text Available Imposex is characterized by the development of masculine sexual organs in neogastropod females. Almost 120 mollusk species are known to present imposex when exposed to organic tin compounds as tributyltin (TBT and triphenyltin (TPT. These compounds are used as biocide agents in antifouling paints to prevent the incrustations on boats. Five gastropod species are known to present imposex in Brazil: Stramonita haemastoma, Stramonita rustica, Leucozonia nassa, Cymathium parthenopeum and Olivancillaria vesica. This paper reports the first record of imposex observed in the endemic gastropod Voluta ebraea from Pacheco Beach, Northeast Brazil. Animals presenting imposex had regular female reproductive organs (capsule gland, oviduct and sperm-ingesting gland and an abnormal penis. As imposex occurs in mollusks exposed to organotin compounds typically found at harbors, marinas, shipyards and areas with high shipping activities, probably contamination of Pacheco Beach is a consequence of a shipyard activity located in the nearest areas.O imposex caracteriza-se pelo surgimento de estruturas sexuais masculinas, em fêmeas de gastrópodes. Cerca de 120 espécies de moluscos que exibem o fenômeno quando expostas a contaminação por compostos orgânicos de estanho tais como o Tributilestanho (TBT e o Trifenilestanho (TPT. Esses compostos são utilizados, sobretudo em embarcações, no intuito de evitar a bioincrustração que danifica as embarcações e eleva os custos das viagens marítimas. No Brasil se conhecem 5 espécies de moluscos gastrópodes que manifestam imposex, são elas: Stramonita haemastoma, Stramonita rustica, Leucozonia nassa, Cymathium parthenopeum e Olivancillaria vesica. No Nordeste, monitoramentos da contaminação por organoestânicos foram realizados utilizando o imposex em gastrópodes como biomarcador.

    Epilepsy is one of the most common neurological conditions globally, estimated to constitute 0.75% of the global burden of disease, with the majority of this burden found in low- and middle- income countries (LMICs). Few studies from LMICs, including much of sub-Saharan Africa, have described the incidence, remission or mortality rates due to epilepsy, which are needed to quantify the burden and inform policy. This study investigates the epidemiological parameters of convulsive epilepsy within a context of high HIV prevalence and an emerging burden of cardiovascular disease. A cross-sectional population survey of 82,818 individuals, in the Agincourt Health and Socio-demographic Surveillance Site (HDSS) in rural northeast South Africa was conducted in 2008, from which 296 people were identified with active convulsive epilepsy. A follow-up survey was conducted in 2012. Incidence and mortality rates were estimated, with duration and remission rates calculated using the DISMOD II software package. The crude incidence for convulsive epilepsy was 17.4/100,000 per year (95%CI: 13.1-23.0). Remission was 4.6% and 3.9% per year for males and females, respectively. The standardized mortality ratio was 2.6 (95%CI: 1.7-3.5), with 33.3% of deaths directly related to epilepsy. Mortality was higher in men than women (adjusted rate ratio (aRR) 2.6 (95%CI: 1.2-5.4)), and was significantly associated with older ages (50+ years versus those 0-5 years old (RR 4.8 (95%CI: 0.6-36.4)). The crude incidence was lower whilst mortality rates were similar to other African studies; however, this study found higher mortality amongst older males. Efforts aimed at further understanding what causes epilepsy in older people and developing interventions to reduce prolonged seizures are likely to reduce the overall burden of ACE in rural South Africa.

    Babassu is considered the largest native oil resource worldwide and occurs naturally in Brazil. The purpose of this study was to evaluate the potential of babassu nut residues (epicarp, mesocarp and endocarp) for bioenergy use, especially for direct combustion and charcoal production. The material was collected in the rural area of the municipality of Sítio Novo do Tocantins, in the state of Tocantins, Brazil. Analyses were performed considering jointly the three layers that make up the babassu nut shell. The following chemical characterizations were performed: molecular (lignin, total extractives and holocellulose), elemental (C, H, N, S and O), immediate (fixed carbon, volatiles and ash), energy (higher heating value and lower heating value), physical (basic density and energy density) and thermal (thermogravimetry and differential thermal analysis), besides the morphological characterization by scanning electron microscopy. Babassu nut residues showed a high bioenergy potential, mainly due to their high energy density. The use of this biomass as a bioenergy source can be highly feasible, given their chemical and thermal characteristics, combined with a low ash content. Babassu nut shell showed a high basic density and a suitable lignin content for the sustainable production of bioenergy and charcoal, capable of replacing coke in Brazilian steel plants.

    To present national estimates regarding walking or cycling for commuting in Brazil and in 10 metropolitan regions. By using data from the Health section of 2008's Pesquisa Nacional por Amostra de Domicílio (Brazil's National Household Sample Survey), we estimated how often employed people walk or cycle to work, disaggregating our results by sex, age range, education level, household monthly income per capita, urban or rural address, metropolitan regions, and macro-regions in Brazil. Furthermore, we estimated the distribution of this same frequency according to quintiles of household monthly income per capita in each metropolitan region of the country. A third of the employed men and women walk or cycle from home to work in Brazil. For both sexes, this share decreases as income and education levels rise, and it is higher among younger individuals, especially among those living in rural areas and in the Northeast region of the country. Depending on the metropolitan region, the practice of active transportation is two to five times more frequent among low-income individuals than among high-income individuals. Walking or cycling to work in Brazil is most frequent among low-income individuals and the ones living in less economically developed areas. Active transportation evaluation in Brazil provides important information for public health and urban mobility policy-making.

  9. Agrarian Social Movements and the Making of Agrodiesel Moral Territories in Northeast Brazil

    Manzi, Maya

    In response to widespread concerns about the socio-ecological impacts of agrofuel production and development, particularly for food security, efforts have been made internationally to implement more sustainable forms of producing agrofuels. Brazil's National Program for the Production and Use of Agrodiesel (PNPB), launched in 2004, is one such attempt. Promoted as a socially and environmentally responsible program, the PNPB was made possible through unprecedented alliances between the 'postneoliberal' Brazilian state, the agribusiness sector, and social movements such as the Rural Trade Union's Movement (MSTTR) and the Landless Rural Workers' Movement (MST). In this research, I critically analyze the unexpected engagement of social movements in the making of agrodiesel territories in semi-arid Bahia, Northeastern Brazil by examining the territorial and moral processes and practices that underlie the production of castor bean (mamona) for agrodiesel. The methodology adopted comprised participant observation, informal and semi-structured interviews (n=74) with leaders and members of the MST and the MSTTR in the territories of the Chapada Diamantina and Irece, in central Bahia. Interviews were also conducted with representatives of family farming cooperatives, government institutions, and agrodiesel companies (Petrobras) in the two study areas and in Salvador, capital of Bahia. Research methods also included the collection and critical discourse analysis of archival and other secondary data sources from public and private institutions. Drawing mainly from cultural geography and political ecology literatures, I argue that social movement leaders enable the making of agrodiesel territories mainly through their role as 'agrodiesel gatekeepers'---as legal interveners, managers, and caregivers. Family farmers tend to enable agrodiesel territorial expansion and to disrupt agrodiesel territorial management by not complying with moral prescriptions of loyalty. I see farmers

    To describe the incidence of congenital heart disease before and after the establishment of a telemedicine screening program, in a reference center from Northeast Brazil. This is a descriptive, retrospective and comparative study based on the institutional data from a reference center in perinatology for a period of 16 years. Institutional data were collected from a 16-year period (2001-15). Data were divided into two periods: prior to (2001-11) and after (2012-15) the establishment of a telemedicine screening program. After the implementation of the screening process, almost all kinds of heart disease showed a significant increase in their incidence (p  <  0.05). With this, the incidence of major heart diseases approached those specified in developed regions. The implementation of a screening process model for congenital heart diseases can change the context of patients with congenital heart diseases in poor regions. © The Author [2016].

    Full Text Available The aim of this work was to study the rheological, thermal and some other physical-chemical properties of selected honeys produced in the Northeast of Brazil. Two samples were produced by native “Jandaira” bees (Melipona subnitida and ten other samples by Africanized bees (Apis mellifera. The samples were analyzed for pH, water activity (aW, soluble solids and water content. Viscosity flow curves were obtained using a rheometer (25ºC, 0-100s-1. Thermal analyses were performed on a differential scanning calorimeter, with heating rate of 10ºC/min (-100 to 100ºC. The water content and the pH of the honey samples varied from 17.2 to 27.9% and from 3.2 to 4.2, respectively, and, the aW of the samples varied from 0.57 to 0.74. Two samples were out of specification with respect to water content, according to Brazilian laws. In relation to rheology, all honey samples showed Newtonian behaviour with no thixotropy or dilatancy. The viscosity varied as an exponential function of the water content. The highest viscosity was obtained for the sample with lower values of water content and aW. Thermograms showed a glass transition (Tg occurring between -52.4 and -42.6ºC, in the samples produced by Apis mellifera and -67.6 and -57.0ºC for the other samples. A linear relationship was obtained between Tg and water content. In conclusion, the honey viscosity depended on the water content of the product. The higher the water value and therefore the greater the aw, the lower viscosity and Tg of the samples.

    Natural infection of armadillos with Coccidioides immitis was studied in the state of Piauí, northeast of Brazil, endemic for coccidioidomycosis. In 1998, 26 nine-banded armadillos (Dasypus novemcinctus) were captured in 4 different counties. The animals were sacrificed under deep anesthesia with ether. At necropsy fragments of spleen, liver, lungs and heart were homogenized and seeded onto Sabouraud dextrose agar with and without cycloheximide (BBL, USA). Part of each organ was also processed for histological examination. Suspected colonies of filamentous fungi observed after the second week of incubation at room temperature, exhibiting barrel-shaped arthroconidia alternating with empty spaces, were inoculated intraperitoneally into mice. Three armadillos proved to be infected with C. immitis. Mice inoculated with suspected colonies obtained from homogenized spleen of three and liver of two armadillos developed disseminated coccidioidomycosis and immature and mature spherules of C. immitis were disclosed in several organs. For the first time armadillos (D. novemcinctus) were found naturally infected with C. immitis, adding new data on the ecology and on a possible role of these ancestral mammals in the evolutionary life cycle of this fungus.

    Geopropolis is a product containing wax, plant resin, and soil particles. It is elaborated by stingless bees of tribe Meliponini. Methanol extracts of sample of geopropolis produced by Scaptotrigona postica ("mandaguari") in the state of Rio Grande do Norte (RN, northeast Brazil) were analyzed for the determination of standard parameters (total phenols, total flavonoids, and radical scavenging activity) and chemical characterization by HPLC-DAD-MS/MS analysis. The sample analyzed has high contents of total phenols and flavonoids, as well as high antioxidant activity. The constituents characterized were mainly flavonols, such as quercetin methyl ethers, and methoxychalcones. Such chemical profile is similar to the composition of a green propolis from the same area of RN, which is produced by Africanized Apis mellifera , using shoot apices of Mimosa tenuiflora , popularly known as "jurema-preta." This finding provides evidence that "mandaguari" geopropolis and honeybee propolis have the same botanical origin in RN. The sharing of a plant resin source by phylogenetically distant bees (Apinae and Meliponinae) suggests that bee genetic factors play little role in the choice of plants for resin collection and that the availability of potential botanical sources plays a decisive role.

    Full Text Available DOI: http://dx.doi.org/10.5007/2175-7984.2016v15nesp1p49 In the past two decades an evident dichotomy has been established between policies of a productive nature and those aimed at social assistance for family farms in Brazil. The purpose of this article is to analyze this duality in the main public policies for family farming, and presents a quantitative overview of the results. From a methodological perspective the analysis was based on the number of farmers who benefit from the agrarian reform policies, rural credit, institutional food markets, rural social security and income transfer. The main results of this study indicate that the economic support for the productive activities of Brazilian family farming have been concentrated among the intermediary and well-established farms that are inserted in markets. In parallel, most family farmers are relegated to social assistance programs and not integrated to the working agendas of the main professional organizations in agriculture.

    In an attempt to locate the presence of possible groundwater resource regions in the semi-arid North-East Brazil, an integrated survey including aeromagnetic and magnetotelluric (MT) studies have been undertaken in the Guaribas region and only MT survey in the Caracol region. In the Guaribas region the aeromagnetic data, its analytic signal and Euler solutions reveal several subsurface small-scale faults and intrusives that are conducive to be potential groundwater resource regions. A total of about 22 broad-band magnetotelluric (MT) soundings in the period range of 0.006-300 s along two profiles on the marginal arcs of the intra-cratonic sedimentary Parnaíba basin in North-East Brazil have been made across the regional geological strike, the Senador Pompeu Lineament (SPL). SPL trends N40°E and marks a basement high reflecting an irregularity in the original basin geometry. While one of the MT profiles traverses across the SPL, the other lies only in the aeromagnetically surveyed sedimentary region. Two-dimensional inversion of MT data of both profiles shows that the sedimentary basin is conductive (100-150 Ω m) and shows as a thin graben with an average thickness of about 2-3 km beneath both profiles. The basin is located to be at shallow depths (from surface to about 500 m). Based on the facts that the study region falls on sedimentary region having low-to-very low permeability and also in accordance with the subsurface lithology around the study region, the mapped sedimentary basin largely manifests the zone of potential sedimentary aquifer having moderate resistivity of 50-250 Ω m and is located at relatively shallow depths. The identified aquifer zone is believed to have links with the Parnaiba River flowing at a distance of about 300 km NW from the study region. We discuss interpretation of our results of MT and aeromagnetic data sets in the light of hydrological features of the study region.

    There has been an increasing concern about current environmental issues caused by human activity, as the world searches for development. The production of electricity is an extremely relevant factor in this scenario since it is responsible for a large portion of the emissions that cause the greenhouse effect. Due to this fact, a sustainable development with alternative energy sources, which are attractive for such purpose, must be proposed, especially in places that are not supplied by the conventional electricity grid such as many communities in the Northeast Brazil. This work aims to calculate the environmental cost for the alternative sources of energy - solar, wind and biomass - during electricity generation, and to estimate the economic feasibility of those sources in small communities of Northeast Brazil, considering the avoided costs. The externalities must be properly identified and valued so the costs or benefits can be internalized and reflect accurately the economic feasibility or infeasibility of those sources. For this, the method of avoided costs was adopted for the calculation of externalities. This variable was included in the equation developed for all considered alternative energy sources. The calculations of economic feasibility were performed taking the new configurations in consideration, and the new equation was reprogrammed in the Programa de Calculo de Custos de Energias Alternativas, Solar, Eolica e Biomassa (PEASEB). The results demonstrated that the solar photovoltaic energy in isolated systems is the most feasible and broadly applicable source for small communities of Northeast Brazil. (author)

  19. On the dynamics of droughts in northeast Brazil - Observations, theory and numerical experiments with a general circulation model

    1981-01-01

    The establishment of a thermally direct local circulation which has its ascending branch at about 10 deg N and its descending branch over northeast Brazil and the adjoining oceanic region is proposed as a possible mechanism for the occurrence of severe droughts over this Brazilian region. The driving for this anomalous circulation is provided by enhanced moist convection due to the effect of warmer sea surface anomalies over the northern tropical Atlantic and cooling associated with colder sea surface temperature anomalies in the southern tropical Atlantic. A simple primitive equation model is used to calculate the frictionally-controlled and thermally-driven circulation due to a prescribed heating function in a resting atmosphere, and a series of numerical experiments are carried out to test the sensitivity of the Goddard Laboratory's model to prescribed sea surface temperature anomalies over the tropical Atlantic.

Paralelamente, faz-se um exame do papel do Estado e da sociedade civil na evolução da legislação relativa à previdência social rural, procurando-se evidenciar seu caráter de "doação" por parte do Estado ou da "conquista" polos próprios trabalhadores(as. Finalmente, são examinados alguns impactos da implantação da previdência social rural no Sul do Brasil, ressaltando-se seu papel na diminuição da pobreza rural e da desigualdade na distribuição da renda, assim como sua importância material e simbólica na mudança de relações de gênero no meio rural.The work analyzes the main transformations in the rural Social Welfare in Brazil. The outcome of these transformations has been the inclusion of rural hard-working women in the welfare system as of the legislation approved by the National Congress in 1988. Rural-work women in Brazil have become entitled to the benefits of paid maternity leave and retirement accordant to a legal age limit. Concurrently, the article examines the role played by the State and the civil society in the unfolding of the legislation related to rural Social Welfare, in an attempt of exposing its character of either a "donation" given by the State or the workers' own "conquest". Finally, the author queries the impact of rural Social Welfare implementation in the South of Brazil, emphasizing its achievements in the decrease of rural poverty and unequal income distribution, as well as its material and symbolic importance in the gender relationship shift in rural areas.

    Aiming to investigate the effect of diet and food consumption with regard to health, environment, and economy in light of nutrition ecology, we studied the dimensions of nutrition and food security in urban and rural settings in the region of Chapada dos Veadeiros, Central Brazil. We tracked diet and food consumption through carbon and nitrogen stable isotope ratios in fingernails of these inhabitants together with food intake data as a proxy for their diet patterns. We estimated household food insecurity by using the Brazilian Food Insecurity Scale. Nutrition and food insecurity was observed in both urban and rural areas, but was accentuated in rural settings. The diet pattern had high δ(13)C values in fingernails and low δ(15)N. Both urban and rural areas have diets with low diversity and relying on low-quality processed food staples at the same time that nutrition and food insecurity is quite high in the region.

    Full Text Available Relationships between simultaneous occurrences of distinctive atmospheric easterly wave (EW signatures that cross the south-equatorial Atlantic, intense mesoscale convective systems (lifespan > 2 hour that propagate westward over the western south-equatorial Atlantic, and subsequent strong rainfall episodes (anomaly > 10 mm·day−1 that occur in eastern Northeast Brazil (ENEB are investigated. Using a simple diagnostic analysis, twelve cases with EW lifespan ranging between 3 and 8 days and a mean velocity of 8 m·s−1 were selected and documented during each rainy season of 2004, 2005, and 2006. These cases, which represent 50% of the total number of strong rainfall episodes and 60% of the rainfall amount over the ENEB, were concomitant with an acceleration of the trade winds over the south-equatorial Atlantic, an excess of moisture transported westward from Africa to America, and a strengthening of the convective activity in the oceanic region close to Brazil. Most of these episodes occurred during positive sea surface temperature anomaly patterns over the entire south-equatorial Atlantic and low-frequency warm conditions within the oceanic mixing layer. A real-time monitoring and the simulation of this ocean-atmosphere relationship could help in forecasting such dramatic rainfall events.

    Background Epilepsy is one of the most common neurological conditions globally, estimated to constitute 0.75% of the global burden of disease, with the majority of this burden found in low- and middle- income countries (LMICs). Few studies from LMICs, including much of sub-Saharan Africa, have described the incidence, remission or mortality rates due to epilepsy, which are needed to quantify the burden and inform policy. This study investigates the epidemiological parameters of convulsive epilepsy within a context of high HIV prevalence and an emerging burden of cardiovascular disease. Methods A cross-sectional population survey of 82,818 individuals, in the Agincourt Health and Socio-demographic Surveillance Site (HDSS) in rural northeast South Africa was conducted in 2008, from which 296 people were identified with active convulsive epilepsy. A follow-up survey was conducted in 2012. Incidence and mortality rates were estimated, with duration and remission rates calculated using the DISMOD II software package. Results The crude incidence for convulsive epilepsy was 17.4/100,000 per year (95%CI: 13.1-23.0). Remission was 4.6% and 3.9% per year for males and females, respectively. The standardized mortality ratio was 2.6 (95%CI: 1.7-3.5), with 33.3% of deaths directly related to epilepsy. Mortality was higher in men than women (adjusted rate ratio (aRR) 2.6 (95%CI: 1.2-5.4)), and was significantly associated with older ages (50+ years versus those 0-5 years old (RR 4.8 (95%CI: 0.6-36.4)). Conclusions The crude incidence was lower whilst mortality rates were similar to other African studies; however, this study found higher mortality amongst older males. Efforts aimed at further understanding what causes epilepsy in older people and developing interventions to reduce prolonged seizures are likely to reduce the overall burden of ACE in rural South Africa.

    The objective of this survey was to investigate the prevalence of Hepatozoon infection in dogs in the rural and urban areas of Uberlândia, Brazil by PCR and molecular characterization. DNA was obtained from blood samples collected from 346 local dogs from both genders and various ages. Seventeen PCR products from positive blood samples of urban dogs and 13 from the rural dogs were sequenced. Partial sequences of the 18S rRNA gene indicated that all 30 dogs were infected with Hepatozoon canis similar in sequence to H. canis from southern Europe. Four local dog sequences were submitted to GenBank (accessions JN835188; KF692038; KF692039; KF692040). This study indicates that H. canis is the cause of canine hepatozoonosis in Uberlândia and that infection is similarly widespread in rural and urban dogs. Copyright © 2014.

    Full Text Available Hepatitis B virus (HBV serological markers were investigated in 40 incident cases of hepatocellular carcinoma (HCC and in two age and sex matched control groups, comprising 40 patients with other cancers and 80 healthy individuals, resident in Bahia, Brazil. Serologic tests were done by radioimmunoassay. The study observed high proportion of seropositivity to HBsAg (42.5% and of those presenting HBsAg or antiHBc (65.0% among HCC cases, higher in men than women and in those aged 17 to 30 years old. HBsAg seropositivity among HCC patients was greater than in the control group with other cancers (7.5% and in healthy controls (2.5%, corresponding to odds ratio estimates of 15.0 (95% CI 3.29, 68.30 and 33.0 (95% CI 9.13, 119.28, both statistically significant. HBeAg was not observed and antiHBe was present in 41.2% of cases, suggesting the absence of viral replication, possibly with viral DNA intergration into the hepatocyte genome. The presence of cirrhosis was associated with HBsAg seropositivity among HCC cases. A history of chronic alcoholism is shown to be more frequently related to those cases with cirrhosis. This study highlights the relevant association between HCC and HBV in Northeast Brazil, particularly for young individuals, and the high risk of development of HCC for HBsAg carriers.

    Full Text Available Pentastomids can infect the respiratory tract of lizards, causing their death and as a result influencing the population size of hosts. Despite this, studies on rates of pulmonary infection of Brazilian lizards, including those living in Caatinga ecosystems of northeastern Brazil are scarce. Active collections of lizards were performed from October to December 2004 in an area of Caatinga of the Estação Experimental de São João do Cariri - EESJC (07º 25' S and 36º 30' W, located in the state of Paraíba, Northeast of Brazil. Forty-five lizards inhabiting granite outcrops in an area of Caatinga were captured, belonging to the following species: Tropidurus hispidus (Spix, 1825 (18 individuals, T. semitaeniatus (Spix, 1825 (15 individuals, Phyllopezus periosus Rodrigues, 1986 (6 individuals, and P. pollicaris (Spix, 1825 (6 individuals. Laboratory examination revealed that all species had some degree of pulmonary infection caused by Raillietiella mottae. The highest rates of prevalence (66.7% and mean intensity of infection (5.25 ± 2.01, range of 2-11 were observed in P. periosus. The results obtained in this study show that lizards of the Brazilian semi-arid region are infected by a generalist species of pentastomid. The most likely cause for such pattern is the similarity in lizards' diets (ants and termites. It is particularly noteworthy that T. semitaeniatus, P. periosus, and P. pollicaris represent new host records for R. mottae.

    2011-12-01

    Full Text Available Given the importance of family farming in food production in Brazil, this review aims to highlight the peculiarities of this productive sector. The labor used in family farming is still not qualified, preventing the application of new technologies in rural activities. This factor is still impressive with regard to management of farms, which is empirically, without sufficient knowledge for entering the market. The meat from sheep sold in Brazil has a large share of the foreign market. The production chain of meat from goat and sheep is dismantled and disorganized, where there is no integration between the chain links. The lack of standard, seasonality of production and low quality products are the limiting factors to the development of this activity in Rio Grande do Norte and the Northeast. Family farming is a palpable alternative to increase the rates of agricultural productivity, take upon them the responsibility to increase food production.

    Full Text Available Hemoglobinopathies are hereditary disorders of the hemoglobin molecule with a high prevalence worldwide. Brazil has a prevalence of 0.1 to 0.3% of newborns with sickle cell anemia and 20.0 to 25.0% of heterozygous alpha2 thalassemia among African Brazilians. In the present study, we investigated the presence of variant hemoglobins and alpha2(3.7 Kb and alpha2(4.2 Kb thalassemia in newborns from Salvador, Bahia, Brazil. Samples of umbilical cord blood from a total of 590 newborns were analyzed, of which 57 (9.8% were FAS; 36 (6.5% FAC; one (0.2% SF; and five (0.9% FSC. One hundred fourteen (22.2% newborns had alpha2(3.7 Kb thalassemia, of whom 101 (19.7% were heterozygous and 13 (2.5% homozygous, showing statistical significance for hematological data between newborns with normal alpha genes and alpha2(3.7 Kb thalassemia carriers. The alpha2(4.2 Kb thalassemia was not found. Frequencies found in the present study confirm that hemoglobinopathies are a public health problem in Brazil, emphasizing the need for neonatal screening and genetic counseling programs.

    Full Text Available This article contributes an analysis of the way in which agents of rural development have elaborated and implemented mechanisms to place value on the local specificities within two states of Brazil’s southern region. Within this context, consideration of biological and cultural diversity from a perspective of sustainable development imposes itself, whether directly or indirectly. We base our argument on two case studies of experiences that promote these mechanisms through placing emphasis on origins: i beef produced in native pastures of Rio Grande do Sul and ii Goethe wine, made in the Urussanga region of Santa Catarina. Both cases are considered illustrative of the current phase of evolution of debates dealing with the interface of geographic origins, protection of national heritage and sustainable rural development. Keywords: rural development, sustainable development, cultural heritage, Southern Brazil.

    This article presents part of the results from the Baseline Studies, an evaluative research conducted in 21 municipalities with more than 100,000 inhabitants each, in three States of Northeast Brazil. The overall objective was to assess experiences in the implementation of the Family Health Program (FHP), with a focus on inductions in the PROESF. An implementation analysis was performed, using the case study method. The analysis focused on these dimensions: political-institutional, health organization, and comprehensive care. Outstanding advances included: prioritize the FHP in high-risk areas; institutional learning, with qualification of managers and teams; definition of institutional levels for regulating the FHP; and health team-user bonds and positive perceptions concerning the program. Challenges included: strengthening of local policy and decision-making capacity; allocation of primary care resources; greater employment security for human resources; effective implementation of the health care network; strengthening of social participation; upgrading of monitoring and evaluation for decision-making; receptivity; waiting lines for tests, appointments, and hospital admissions; implementation of teamwork; health promotion and inter-sector activities.

    This paper describes a joint US/Brazil pilot project for rural electrification, whose major goals are: to establish technical, institutional, and economic confidence in using renewable energy (PV and wind) to meet the needs of the citizens of rural Brazil; to establish on-going institutional, individual and business relationships necessary to implement sustainable programs and commitments; to lay the groundwork for larger scale rural electrification through the use of distributed renewable technologies. The projects have supported low power home lighting systems, lighting and refrigeration for schools and medical centers, and water pumping systems. This is viewed as a long term project, where much of the equipment will come from the US, but Brazil will be responsible for program management, and sharing data gained from the program. The paper describes in detail the Brazilian program which was instituted to support this phased project.

  12. "Stuck in the muck": an eco-idiom of distress from childhood respiratory diseases in an urban mangrove in Northeast Brazil.

    Nations, Marilyn; Gondim, Ana Paula Soares

    2013-02-01

    Situated in neo-democratic globalizing Northeast Brazil, this anthropological study probes the role of ecological context in framing, experiencing, and expressing human distress. Ethnographic interviews, narratives, and "contextualized semantic analysis" reveal the lived experience of childhood respiratory diseases among 22 urban mangrove dwellers. Informants speak an "eco-idiom of respiratory distress" based on a popular "eco-logic", reflecting the harsh reality of "living in dampness". "Higher-up" residents legitimize their feelings of superiority by stigmatizing "lowlanders" as taboo, diseased (with porcine cysticercosis, swine flu) "filthy pigs, stuck in the muck" (atolados na lama). Animalizing inhabitants' identities demotes them to nonpersons. Besides infections, children suffer social stigma, ostracism, and barriers for accessing care. Promoting a "favorable environment" requires reducing ecological risk, challenging class-based prejudice, and restoring human dignity.

    Full Text Available The influence of abiotic factors on the spatial distribution of the fiddler crabs Uca leptodactyla, U. maracoani, U. rapax and U. thayeri was studied in a tropical mangrove of northeast Brazil. Eight transects were delimited in a mangrove area of the Pacoti River. On each transect, three 0.25 m2 squares were sampled during spring low tide periods from September 2003 to August 2004. The sediment of the squares at each transect was analysed for grain size, organic matter and humidity. Morphology of the second maxilliped was studied considering the number of spoon-tipped setae to help explain the ecological distribution of the species. U. leptodactyla and U. rapax were found living in medium sand, U. thayeri was collected in fine and very fine sand, while U. maracoani was found living in very fine sand. U. leptodactyla showed a negative correlation with organic matter and humidity while U. thayeri showed a positive correlations for both factors. U. maracoani and U. rapax were not correlated with organic matter or humidity. The analysis of the second maxilliped revealed that U. leptodactyla and U. rapax show a high quantity of spoon-tipped setae while U. maracoani and U. thayeri show a greater quantity of plumose setae.

    Full Text Available This study estimates the factors of artificial environments (houses and peridomestic areas associated with Triatoma sordida occurrence. Manual searches for triatomines were performed in 136 domiciliary units (DUs in two rural localities of Central-West Brazil. For each DU, 32 structural, 23 biotic and 28 management variables were obtained. Multiple logistic regression analysis was performed in order to identify statistically significant variables associated with occurrence of T. sordida in the study areas. A total of 1,057 specimens (99% in peridomiciles, mainly chicken coops of T. sordida were collected from 63 DUs (infestation: 47%; density: ~8 specimens/DU; crowding: ~17 specimens/infested DU; colonisation: 81%. Only six (0.6% out of 945 specimens examined were infected with Trypanosoma cruzi. The final adjusted logistic regression model indicated that the probability of T. sordida occurrence was higher in DU with wooden chicken coops, presence of > 30 animals in wooden corrals, presence of wood piles and presence of food storeroom. The results show the persistence of T. sordida in peridomestic habitats in rural localities of Central-West Brazil. However, the observed low intradomestic colonisation and minimal triatomine infection rates indicate that T. sordida has low potential to sustain high rates of T. cruzi transmission to residents of these localities.

    cities, the percentage of “owned” households was high in both 2000 and 2010. As regards “unowned” households, it is important to highlight the amount of households managed as real estate for rent. The expansion of this type of real estate may well relativize the supposed advantages of the expansion of household real estate. What should also be noted is the increase in the proportion of rented urban households over this period in all States of the Federal Union. The most significant increases occurred in the North (8.2%, Northeast (6.2%, and Midwest (6.0% regions of the country. To note, all the states in the North, Midwest, and Northeast regions (except for Ceará, and the states of Espírito Santo and Santa Catarina, are above the mean national growth rate (4.7%. Thus, it can be inferred that where there is an accelerated expansion of “owned” real estate, there is also a simultaneous acceleration of the supply of real estate for rent. A decline in households deemed inappropriate is also evident. There are data indicating that until 2000, at least 80.7% of one-bedroom households were located in urban areas. In 2010, a sharp decline of 10 per cent points (67.2% could be observed in this proportion, demonstrating that precarious housing still remains and is high in rural areas: 169,450 one-bedroom households in 2000 and 183,881 in 2010. In relative terms, these figures account for 32.6% of the total number of rural households in 2000 and 43.8% in 2010. Also important is that in urban Brazil, approximately 22% of households rented in 2010 were in fact occupied; this is due primarily to excessive rental prices, i.e. households in which low-income families spend more than 30% of their income. Even more relevant is that in the five major regions, this proportion is approximately 20%. The southeast, where the number of activities that produce jobs is much greater and the presence of “owned” and “unowned” households is larger, is also the area where excessive

    Full Text Available Abstract The study aimed to assess the food accessibility and consumption among families in the Cupiúba rural settlement, in the city of Castanhal, Pará, Brazil. It was found that the access to food is worrying and indicated that most families are in food insecurity conditions. Moreover, income and food safety level were associated. The consumption of the settler families comprises mainly high-energy, low-nutrient content foods, characterized by the low intake of fruits and vegetables and the introduction of processed foods with high energy density and sugar-added beverages, although the traditional dietary habits (rice and beans are still present. This configures a diet at risk for important nutritional deficits, obesity, and many non-communicable chronic diseases.

    Zhao, Chao

    Purpose of the study. The purpose of this research was to survey those individuals teaching science in the middle schools of the Shenyang area, Northeast China. Specifically, the study attempted to differentiate between rural and nonrural teachers with respect to demographic differences, problem areas, instructional activities, and perceived needs. Procedure. A 100-item survey was used to collect data for this study. The sample consisted of 224 science teachers (Rural 114, nonrural 110) who taught at least science class in 1996--97 academic year in a middle school of Shenyang area, Northeast China. Frequencies and percentages presented the needs of the teachers. The differences between rural and nonrural groups were analyzed by Chi Square statistics. Findings. Almost three quarters (74.9%) of returns were younger than 41, and 43.9% of returns held no degree. Significant differences were fond between rural and nonrural groups according to age, classroom experience, school enrollment, lab activities, motivating students to learn science, using science test data bank, peer tutoring and evaluating your own instructional effectiveness as a science teacher. Rural and nonrural teachers shared 10 of 14 greatest needs. Conclusions. Teacher in-service program designers need to establish academic training programs which lead to entry level degrees and certificates and improve young teacher's instructional skills. Increased efforts should be given to meet the perceived needs addressed in this study in order to improve teachers' teaching and students' learning. Lack of person energy or motivation and program fail to meet teachers' needs were considered as barriers of attending inservice programs.

    This article examines the factors associated with the notification of occupational accidents by sentinel workers' health centers in the municipality of Fortaleza in the northeast of Brazil. An analytical cross-sectional study was conducted of five sentinel workers' health centers for serious and fatal occupational accidents. A total of 354 interviews were conducted with professionals responsible for notifying occupational accidents. Bivariate analysis was conducted using Pearson's chi-square test and/or Fisher's exact test using prevalence ratios and 95% confidence intervals, followed by stratified analysis and multivariate Poisson regression adopting the stepwise forward method. Variables that obtained a p-value of less than or equal to the chosen significance level (0.05) were maintained in the final model. Professionals who had a greater number of years of work experience, had undertaken three training courses, had knowledge of policy directives concerning occupational accidents, were familiar with the SINAN notification form, were aware that occupational accidents are reportable, and discussed the theme of occupational accidents in the workplace were statistically more likely to notify occupational accidents. Education and training helps raise awareness among health professionals.

In order to achieve such measurement, poverty indicators such as Foster, Greer and Thorbecke (FGT were adapted into a time poverty mode. Additionally, an analysis of its determinants was also conducted. Among other findings, the fact that women (either children and adult ones are the time-poorest individuals in urban or rural areas. Another unfortunate finding is that the high rate of time poverty among children, numerically 16,1% is not far from the adult rate which is of 19,7%. The overall composite time poor individual profile is of an African-Brazilian adult woman of little education, not necessarily income poor and residing in an urban area of the northeast region, living in a household of few people, she is the mother of children who are younger than 14 years old.

  2. A robust poverty profile for Brazil using multiple data sources

    2003-01-01

    Full Text Available This paper presents a poverty profile for Brazil, based on three different sources of household data for 1996. We use PPV consumption data to estimate poverty and indigence lines. ''Contagem'' data is used to allow for an unprecedented refinement of the country's poverty map. Poverty measures and shares are also presented for a wide range of population subgroups, based on the PNAD 1996, with new adjustments for imputed rents and spatial differences in cost of living. Robustness of the profile is verified with respect to different poverty lines, spatial price deflators, and equivalence scales. Overall poverty incidence ranges from 23% with respect to an indigence line to 45% with respect to a more generous poverty line. More importantly, however, poverty is found to vary significantly across regions and city sizes, with rural areas, small and medium towns and the metropolitan peripheries of the North and Northeast regions being poorest.

    Intestinal parasitic infections are considered a serious public health problem and widely distributed worldwide, mainly in urban and rural environments of tropical and subtropical countries. Globally, soil-transmitted helminths and protozoa are the most common intestinal parasites. Blastocystis sp. is a highly prevalent suspected pathogenic protozoan, and considered an unusual protist due to its significant genetic diversity and host plasticity. A total of 294 stool samples were collected from inhabitants of three rural valleys in Rio de Janeiro, Brazil. The stool samples were evaluated by parasitological methods, fecal culture, nested PCR and PCR/Sequencing. Overall prevalence by parasitological analyses was 64.3% (189 out of 294 cases). Blastocystis sp. (55.8%) was the most prevalent, followed by Endolimax nana (18.7%), Entamoeba histolytica complex (7.1%), hookworm infection (7.1%), Entomoeba coli (5.8%), Giardia intestinalis (4.1%), Iodamoeba butchilii (1.0%), Trichuris trichiura (1.0%), Pentatrichomonas hominis (0.7%), Enterobius vermicularis (0.7%), Ascaris lumbricoides (0.7%) and Strongyloides stercoralis (0.7%). Prevalence of IPIs was significantly different by gender. Phylogenetic analysis of Blastocystis sp. and BLAST search revealed five different subtypes: ST3 (34.0%), ST1 (27.0%), ST2 (27.0%), ST4 (3.5%), ST8 (7.0%) and a non-identified subtype. Our findings demonstrate that intestinal parasite infection rates in rural areas of the Sumidouro municipality of Rio de Janeiro, Brazil are still high and remain a challenge to public health. Moreover, our data reveals significant genetic heterogeneity of Blastocystis sp. subtypes and a possible novel subtype, whose confirmation will require additional data. Our study contributes to the understanding of potential routes of transmission, epidemiology, and genetic diversity of Blastocystis sp. in rural areas both at a regional and global scale.

    Children's exposure to metals can result in adverse effects such as cognitive function impairments. This study aimed to evaluate some toxic metals and levels of essential trace elements in blood, hair, and drinking water in children from a rural area of Southern Brazil. Cognitive ability and δ-aminolevulinate dehydratase (ALA-D) activity were evaluated. Oxidative stress was evaluated as a main mechanism of metal toxicity, through the quantification of malondialdehyde (MDA) levels. This study included 20 children from a rural area and 20 children from an urban area. Our findings demonstrated increase in blood lead (Pb) levels (BLLs). Also, increased levels of nickel (Ni) in blood and increase of aluminum (Al) levels in hair and drinking water in rural children were found. Deficiency in selenium (Se) levels was observed in rural children as well. Rural children with visual-motor immaturity presented Pb levels in hair significantly increased in relation to rural children without visual-motor immaturity (p < 0.05). Negative correlations between BLLs and ALA-D activity and positive correlations between BLLs and ALA-RE activity were observed. MDA was significantly higher in rural compared to urban children (p < 0.05). Our findings suggest that rural children were co-exposed to toxic metals, especially Al, Pb and Ni. Moreover, a slight deficiency of Se was observed. Low performance on cognitive ability tests and ALA-D inhibition can be related to metal exposure in rural children. Oxidative stress was suggested as a main toxicological mechanism involved in metal exposure.

    The aim of this study was to evaluate the impact of the Bolsa Família Program (PBF) on food consumption in the northeast and southeast regions of Brazil. The database was obtained from the individual food consumption module of the Household Budget Survey conducted in 2008-09. Consumption was assessed through two food records. The food was categorized into four groups: fresh or minimally processed food; culinary ingredients; processed food; and ultra-processed food. To analyze the impact, the propensity score matching method was used, which compares the individual recipients and non-recipients of the PBF in relation to a group of socioeconomic characteristics. After the propensity score was calculated, the impact of the PBF was estimated through the nearest-neighbor matching algorithm. In both regions, more than 60% of the daily total calories consumed by PBF recipients came from foods that had not undergone industrial processing. The recipients of PBF had a low level of consumption of processed and ultra-processed food in both regions, and an increased level of consumption of fresh or minimally processed food in the northeast. The results indicate the importance of adopting intersectoral policies in parallel to the PBF in order to strengthen healthy eating practices.

    A study of viability of alternative energy sources for typical communities of the North or Northeast of Brazil, which do not have access to the electric energy is performed. Brazil presents a great economic and social disparity among its several regions. There are several poor communities, mainly in regions far from big cities, without electrical energy. The Brazilian government has a program known as 'Luz para Todos' (Light for All). The big challenge of this program is to bring electrical energy for everyone using new alternatives energy sources. In this work initially a literature review was made concerning the following alternative energy source: wind, solar and biomass. These energy sources can be used to supply the demand to bring electrical energy for poor communities. For this work it is intended to choose a community that has population between 1,000 and 10,000 and does not have access to electrical energy. For this community an economic viability study will be made to evaluate alternative energy sources. The best energy source resulted from the point of view of the economic viability study will be implemented in that community. A new study will be performed to evaluate cost and environmental impact. In this new study the future social development of the community caused by the installation of electrical energy will be considered. Also, this best energy source will be compared with the new generation of nuclear reactors, for instance , the IRIS reactor. (author)

    Full Text Available Background/Aims: We aim to investigate the extent to which depression and quality of life might be associated with decreased glomerular filtration rate (GFR in a large hypertensive population in rural Northeast China. Methods: A total of 5566 hypertensive participants aged 35 years and older were screened with a stratified cluster multistage sampling scheme in rural areas of Liaoning Province during 2012-2013. Decreased GFR was defined as estimated GFR 2. Results: The overall prevalence of decreased GFR was 3.2%. In the multivariable regression model, participants with moderate or greater depression had a greater risk for having a decreased GFR (OR: 1.739, 95%CI: 1.004 to 3.014 after full adjustment. Every 1-point increase of all the domains in WHOQOL-BREF, except for physical and environment domains, was significantly related to a lower risk for decreased GFR adjusting for age, gender and race. However, after fully adjustment, only social relations remained significant (OR: 0.899, 95%CI: 0.820 to 0.985. Increasing in total scores of WHOQOL-BREF was a protective factor against decreased GFR after fully adjustment. Conclusion: We found that moderate or greater depression and lower quality of life were associated with higher risks for developing decreased GFR.

    National programs of salt iodization were implemented in Brazil to combat iodine deficiency (ID) in children of school age. Currently, there are limited data in Brazil on those still vulnerable to this deficiency and the state of nutritional iodine status in the northeast region of Brazil, where children are vulnerable to malnutrition. The aim of this study was to analyze the iodine nutritional status, household food insecurity, socioeconomic and demographic characteristics among schoolchildren from the public school system living in state the state of Bahia, Brazil. A cross-sectional study was conducted on 1419 schoolchildren in Bahia between the ages of 6 and 14 years old. Anthropometric parameters, urinary iodine concentrations (UIC), and thyrotropin (TSH) measurements were evaluated from blood spots on filter paper. The mean UIC was 206.4 ± 80.5 μg/L, with a median of 221.6 μg/L, indicating sufficient iodine intake in the region. Low urinary iodide concentration (300 μg/L, indicating the coexistence of excessive iodine intake (EII). The mean TSH was 1.0 ± 0.6 mIU/L. The body mass index category "overweight/obesity" was a protective factor against EII (odds ratio [OR] = 0.64 [confidence interval (CI) 0.4-1.0]; p = 0.07). Urban areas (73%) had a mean UIC of 213.1 ± 80 μg/L compared with 176.8 ± 76.1 μg/L in rural areas. The risk for EII increased in children living in a house with more than six people (OR = 1.62 [CI 0.9-2.6]; p  0.05). A significant proportion of schoolchildren still have ID or EII in the northeast region of Brazil, emphasizing the importance of committed public policies to address this problem. Socioeconomic factors and the lack of education about nutritional importance of iodine were important influencing factors in the presence of ID in schoolchildren.

    Universal access to electricity is deemed critical for improving living standards and indispensable for eradicating poverty and achieving sustainable development. In 2003, the ‘Luz para Todos’ (LpT—Light for All) program was launched aiming to universalize access to electricity in Brazil. The program focused on rural and isolated areas, also targeting to bring development to those regions along with electrification. This paper evaluates the results of the LpT program in improving socio-economic development in the poorest regions of Brazil. After an initial qualitative analysis, an empirical quantitative assessment of the influence of increased electrification rates on the components of the Human Development Index (HDI) is performed. The empirical results of this study showed that electrification had a positive influence on all dimensions of the HDI, with the education component having the strongest effect. Although complementary policies were needed to achieve this, results show that electricity access is a major requirement to improve quality of life.

    Cesium-137 is an anthropogenic radionuclide introduced in the environment in the early of 1960s to the end of 1970s. The Cesium-137 has very used to assess soil redistribution in the landscape because this is very tight in the fine soil particles and its movement in the landscape is due to soil redistribution. To use Cesium-137 to assess soil redistribution is need to known the Cesium-137 inventory in an area that not has experimented soil erosion neither soil deposition. So, this work present Cesium-137 inventories in undisturbed areas in different regions of Brazil, from South to Northeast of Brazil. The inventories in these areas represent the variational deposition of Cesium-137 in the whole national territory of Brazil. The inventories of Cesium-137 varied from 200 +- 15 Bq.m{sup -2} for South region to 15 +- 2 Bq.m{sup -2} for Northeast region. Moreover, was verified that the Cesium- 137 inventories depend on latitude and altitude of the area. (author)

    Future climate change impacts on humans will be determined by the convergence of evolving physical climate and socioeconomic systems. Of particular concern is the intersection of extreme events and vulnerable populations. Rural areas of the Northeastern United States have experienced increased temperature and precipitation extremes, especially over the past three decades, and face unique challenges due to their physical isolation, natural resources dependent economies, and high poverty rates. To explore the impacts of future extreme events on vulnerable, rural populations in the Northeast, we project extreme events and vulnerability indicators to identify where changes in extreme events and vulnerable populations coincide. Specifically, we analyze future (2046-2075) maximum annual daily temperature, minimum annual daily temperature, maximum annual daily precipitation, and maximum consecutive dry day length for Representative Concentration Pathways (RCP) 4.5 and 8.5 using four global climate models (GCM) and a gridded observational dataset. We then overlay those projections with estimates of county-level population and relative income for 2060 to calculate changes in person-events from historical (1976-2005), with a focus on Northeast counties that have less than 250,000 people and are in the bottom income quartile. We find that across the rural Northeast for RCP4.5, heat person-events per year increase tenfold, far exceeding decreases in cold person-events and relatively small changes in precipitation and drought person-events. Counties in the bottom income quartile have historically (1976-2005) experienced a disproportionate number of heat events, and counties in the bottom two income quartiles are projected to experience a greater heat event increase by 2046-2075 than counties in the top two income quartiles. We further explore the relative contributions of event frequency, population, and income changes to the total and geographic distribution of climate change

    Full Text Available The shelf life of milk and milk derivatives is directly related to the microbiological quality of refrigerated raw milk. Spoilage microorganisms with proteolytic and/or lipolytic properties are primarily responsible for the decrease in the quality of milk, which is reflected in the shelf life of pasteurized milk and all derivatives. The aim of this study was to determine the spoilage microbial load of refrigerated raw milk from the northeast and southern regions of Brazil, which have different climatic and technological conditions of production. We evaluated 46 samples of milk from the state of Paraná in the southern region, and 10 samples of milk from the state of Maranhão in the northeast region, totaling 56 samples collected from November 2013 to November 2014. The producers of Paraná were divided into large (20 or small (26 according to the average daily production. All producers of Maranhão were considered small (<500L/day. The proteolytic and lipolytic microorganism counts were conducted in milk agar and tributyrin agar, respectively. Milk from the large producers of Paraná had average counts of 1.4 × 104 CFU/mL for proteolytic microorganisms and 1.2 × 103 CFU/mL for lipolytics microorganisms, significantly (p <0.05 lower than the small producers in the same state, and the producers of Maranhão. Producers of Maranhao had counts of 1.1 × 105 CFU/mL for proteolytic microorganisms and 2 × 105 CFU/mL for lipolytic microorganisms, with the proteolytic count significantly lower than that of small Paraná producers. The amount of proteolytic and lipolytic spoilage microorganisms in milk is influenced by the adaptation of the microorganisms to cold, promoted by the cooling of milk, which is practiced less frequently in the country’s northeastern region. The amount of spoilage microorganisms is also affected by the implementation of milking hygiene practices, which reduce contamination. Such practices are more frequently and efficiently

    Full Text Available This study investigated the presence and antibiotic resistance of Salmonella spp. in a shrimp farming environment in Northeast Region of Brazil. Samples of water and sediments from two farms rearing freshwater-acclimated Litopenaeus vannamei were examined for the presence of Salmonella. Afterwards, Salmonella isolates were serotyped, the antimicrobial resistance was determined by a disk diffusion method, and the plasmid curing was performed for resistant isolates. A total of 30 (16.12% of the 186 isolates were confirmed to be Salmonella spp., belonging to five serovars: S. serovar Saintpaul, S. serovar Infantis, S. serovar Panama, S. serovar Madelia, and S. serovar Braenderup, along with 2 subspecies: S. enterica serovar houtenae and S. enterica serovar enterica. About twenty-three percent of the isolates were resistant to at least one antibiotic, and twenty percent were resistant to at least two antibiotics. Three strains isolated from water samples (pond and inlet canal exhibited multiresistance to ampicillin, tetracycline, oxytetracycline, and nitrofurantoin. One of them had a plasmid with genes conferring resistance to nitrofurantoin and ampicillin. The incidence of bacteria pathogenic to humans in a shrimp farming environment, as well as their drug-resistance pattern revealed in this study, emphasizes the need for a more rigorous attention to this area.

    The Pernambuco Endemism Center in north-east Brazil has the most fragmented forest cover and the largest number of threatened birds of the whole Atlantic Forest. We analyzed the distribution of three groups of bird species: forest-dependent, endemic and/or threatened using the interpolation method of Inverse Distance Weighting. We also checked the concentration of these birds in protected and unprotected areas, suggesting new sites that need to be protected. The richness concentration of forest-dependent, endemic and/or threatened birds in 123 sites were analysed. There was a greater concentration of the three groups in north Alagoas, south and north Pernambuco, and north and west Paraíba. The distribution of the three groups was almost regular in different vegetation types, although a lower concentration was found in the pioneer formation. There was a greater concentration of birds from all three groups between Pernambuco and Alagoas, and this must be due to the presence of more forest fragments with better structure and vegetation heterogeneity. The protected and unprotected areas hosted important records of endemic and/or threatened birds. We suggested some important places for implementation of new protected areas due to the larger concentrations of the target birds and because they are located within the boundaries of the Important Bird Areas.

    Full Text Available This work is based on the study of the core T1 collected in the Guaratiba Mangrove, located on the northeastern margin of Sepetiba Bay. Few studies dealing with the application of benthic foraminifera to study sea level changes during the Holocene have been conducted in Sepetiba Bay, State of Rio de Janeiro, Brazil. In order to fill this gap, the core T1 was studied using textural, geochemical (carbonate, total organic carbon, total sulfur and stable isotopes evaluated in Ammonia tepida and microfaunal (benthic foraminifera data, unveiling paleoecological relationships of these organisms and the evolutionary scenario of Guaratiba Mangrove. Radiocarbon results indicate an estimated age of about 2400 yrs cal BP for the core base. Textural, geochemical and benthic foraminifera data suggest that the study area changed significantly during the last 2400 yrs cal BP. It experienced coastal waves action and shoreface processes in the period between ≈2.400-1.400 yrs cal BP; then, this phase gave place to a shallow marine environment similar to that found currently in internal and protected areas of Sepetiba Bay, between ≈1.400-350 yrs cal BP. Thenceforth, the study area evolved to the present mangrove environment. Factors related to climatic oscillations and the formation, evolution and events of rupture of Marambaia sand ridge influenced the late Holocene evolution of the northeast intertidal area of Sepetiba Bay.

    Full Text Available ABSTRACT: We describe the epidemiological, clinical and pathological features of five cases of pythiosis in dogs in northeast semiarid. The disease occurred in dogs with age between one and three years, females and males of different breeds. The dogs were created in urban areas, but were occasionally taken to the countryside and then had contact with wetlands. The main clinical signs were weight loss, vomiting, diarrhea and tenesmus. Macroscopically there were intestinal wall thickening with irregular firm masses with yellowish granular areas interspersed with a whitish tissue, involving the duodenum, colon and rectum, extending to the lymph nodes and pancreas, and the vagina and liver. In the skin there were areas of alopecia and irregular ulcerations, some containing small cavitations with serosanguineous secretion. Microscopically there were pyogranulomatous inflammation and in one case also there were eosinophilic necrosis associated with negative images tubuliformes by hematoxylin and eosin, strongly stained by GMS and weakly by PAS. Hyphae were strongly marked by immunohistochemistry with polyclonal anti-Pythium insidiosum. The disease occurs sporadically in dogs in the semiarid Northeast, however should be included in the differential diagnosis of chronic diseases and proliferative aspect of the gastrointestinal system, and front skin lesions of difficult treatment.

    Full Text Available Abstract Objective: To evaluate factors associated with neonatal death within 24 hours after birth in very low birth weight preterm newborns. Methods: Prospective cohort of live births with gestational age of 230/7–316/7 weeks, birth weight of 500–1499g without malformations, in 19 public maternity hospitals in nine capitals in northeastern Brazil from July to December 2007. The 19 hospitals were assessed in relation to physical resources, equipment, human resources and aiming at quality in care initiatives. Hospital, maternal and neonatal characteristics, neonatal morbidity, neonatal procedures and interventions were compared between preterm newborns that died or survived up to 24 hours of life. The variables associated with death within 24 hours after birth were determined by logistic regression. Results: Of the 627 newborns enrolled in the study, 179 (29% died within 168 hours after birth, of which 59 (33% up to 24 hours and 97 (54% up to 48 hours after birth. The variables associated with death <24h were: weight <1000g (2.94; 1.32–6.53, 5th minute Apgar <7 (7.17; 3.46–14.88, male gender (2.99; 1.39–6.47. A better hospital structure was a protective factor for early neonatal death (odds ratio: 0.34; 95% confidence interval: 0.17–0.71. Conclusions: The high neonatal mortality on the first day of life in capital cities of Northeast Brazil is associated with biological variables such as weight and gender of the newborn, as well as low vitality at birth and a worse infrastructure of the hospital where the birth occurred.

    Full Text Available The seroprevalence of Chagas disease in humans and the presence of triatomines were investigated in a rural locality in the State of Ceará, Brazil, an historically endemic region. Approximately 80% of the surveyed residents agreed to undergo serological tests. Intradomestic and peridomestic environments were searched for triatomines in both the dry and rainy seasons. The prevalence rate of Chagas disease was 1.2% and the majority of individuals confirmed with the disease over 50 years of age. A total of 761 specimens of triatomines were captured, most of which were from colonies composed of nymphs and adult bugs, and the majority of specimens were obtained in the dry season. Triatoma brasiliensis was the predominant species. Analysis using light microscopy revealed that 28.6% of the insects were Trypanosoma cruzi positive. Results suggest that peridomestic man-made structures, such as animal shelters, improper storage of timber and uninhabited dwellings contribute to the high rate of triatomine infestation in the area.

    Poor growth and intestinal parasitic infections are widespread in disadvantaged urban children. This cross-sectional study assessed factors influencing poor growth and intestinal parasites in 376 children aged three to six years in daycare centers in Salvador, in the Northeast Region of Brazil. Data was obtained from seven daycare centers on child weight, height, socio-economic status, health and intestinal parasites in stool samples. Prevalence of moderate underweight ( -2SD), wasting and stunting was 12%, 16% and 6% respectively. Socioeconomic status, birth order, and maternal weight were predictors of poor anthropometric status. Almost 30% of children were infected with more than one intestinal parasite. Helminths (17.8%), notably Trichuris trichiura (12%) and Ascaris lumbricoides (10.5%), and protozoan Giardia duodenalis (13%) were the most common types of parasites detected. One percent of children had hookworm and Cryptosporidium sp. and 25% had non-pathogenic protozoan cysts. Boys from families with very low socio-economic status had lower linear growth and presented a greater risk of helminth infection. Deworming is considered an alternative for reducing the prevalence of intestinal parasitic infections in this age group.

    Successive studies attempting to clarify national aspects of ethanol demand have assisted policy makers and producers in defining strategies, but little information is available on the dynamic of regional ethanol markets. This study aims to analyze the characteristics of ethanol demand at the regional level taking into account the peculiarities of the developed center-south and the developing north-northeast regions. Regional ethanol demand is evaluated based on a set of market variables that include ethanol price, consumer's income, vehicle stock and prices of substitute fuels; i.e., gasoline and natural gas. A panel cointegration analysis with monthly observations from January 2003 to April 2010 is employed to estimate the long-run demand elasticity. The results reveal that the demand for ethanol in Brazil differs between regions. While in the center-south region the price elasticity for both ethanol and alternative fuels is high, consumption in the north-northeast is more sensitive to changes in the stock of the ethanol-powered fleet and income. These, among other evidences, suggest that the pattern of ethanol demand in the center-south region most closely resembles that in developed nations, while the pattern of demand in the north-northeast most closely resembles that in developing nations. - Research highlights: → Article consists of a first insight on regional demand for ethanol in Brazil. → It proposes a model with multiple fuels, i.e., hydrous ethanol, gasohol and natural gas. → Results evidence that figures for regional demand for ethanol differ amongst regions and with values reported for national demand. → Elasticities for the center-south keep similarities to patterns for fuel demand in developed nations while coefficients for the north-northeast are aligned to patterns on developing countries.

    Full Text Available This work aims to analyze the epidemiological profile of human poisoning by rodenticides in Brazil and Regions, in the period 2000 to 2008. This is a descriptive epidemiological study based on secondary data from the National System of Toxic- harmacological Information. Calculations were performed in the incidence rate and fatality rate. The North and Northeast regions had the highest mortality rates for the period. Children from 1 to 4 years had high incidence in all regions except in Northeast, where teenagers were most affected. The rodenticide poisoning was more incident in urban areas and among females, and had attempt suicide as predominant circumstance. Although most cases have evolved for healing, there was almost 40% unconfirmed healing in the South region and 57% of ignored evolution in Southeast. Deaths caused by ingestion of rodenticides were below 5%. The rodenticide poisoning has remained in Brazil with a major public health problem and, despite the differences in the country, the poisoning profile did not change significantly between different regions.

The papers starts with general contextualization of the Brazilian rural situation after a decades of structural reforms followings the discussion of thesis against and favorable the land reform. On the one side we observe that exist an expressive number of researchers that are defending the land reform because they are understanding that this policy is very important to combat the poverty and social inequalities, and the other side we saw also another group of researchers that are against the land reform because they believe that the time for the land reform is already gone. We concluded that academic debate about agrarian reform now is less important than it was in the post war period, especially in the 1960s.

    Full Text Available Objective: To analyze the satisfaction of users of the Family Health Strategy in relation to the Reliability and Safety aspects. Method: This is a quantitative research carried out with 353 participants enrolled in an Integrated Health Center of the eastern region of a capital in the Northeast Brazil, through the SERVQUAL instrument. The data collection took place from January to May 2015, the research was approved by the Ethics and Research Committee of the UNINOVAFAPI University Center. Results: The results indicated that in the Reliability dimension, participants agreed that the healthcare professionals record the attendance, perform on the promised date and have an interest in solving the problems. In the Security dimension, the majority of the participants were indifferent as to the behavior of the professionals generating confidence. They demonstrated security in requesting the services because they were politely attended by the professionals. Moreover, in the two dimensions analyzed, it was noticed that there is a tendency to increase satisfaction as the participants' income decreases with significant statistical relations, with satisfaction on Reliability and Security inversely proportional to income. Conclusion: It is considered that users of the Family Health Strategy have demonstrated satisfaction with the services received, however, there is a need for more studies with different methodological approaches to better elucidate the intersubjective issues that shape the process of interaction between users, healthcare professionals and services. Keywords: Family health; patient satisfaction; security.

    Full Text Available The aim of this article is to describe and analyze sociodemographic characteristics of rural women working in family livestock, inserted in Brazil without Poverty Plan in Encruzilhada do Sul. This type of work is culturally defined as masculine as well, the question is how women in it operate. In Rio Grande do Sul, the southern half has in beef cattle the main productive activity which alludes to a supposed production homogeneity. This condition challenges and boost research that shows the multiplicity of experiences of livestock rural families. Thus, the motivation of this article also is based on the problem of discussion little debated on family livestock, for example, the sexual division of labor and women's participation in the activity. So it was found the presence of women in family livestock and their inclusion in the Brazil without Poverty Program. The information analyzed shows that 92.31% of ownership in the program are women, 6.59% of men and 1.10% for both. This reality leads the female role of idea in action, however it is necessary to consider other issues that contribute to other explanatory possibilities of this condition. The trajectory and the sexual division of labor "earmarking" women to the most precarious jobs, it may be a potential answer. Thus, the recognition of women's work is hindered in social practices and intra-family and sexual division of labor is reaffirmed by the notions of what is "man of affairs and women's things". The issues that emerge interrelate livestock, poverty and gender, since most of the families of the Brazil without Poverty is also included in the livestock. We question the extent to which livestock is male activity and poverty would be a "parameter" to characterize rural activities, including livestock, as female?

The richness concentration of forest-dependent, endemic and/or threatened birds in 123 sites were analysed. There was a greater concentration of the three groups in north Alagoas, south and north Pernambuco, and north and west Paraíba. The distribution of the three groups was almost regular in different vegetation types, although a lower concentration was found in the pioneer formation. There was a greater concentration of birds from all three groups between Pernambuco and Alagoas, and this must be due to the presence of more forest fragments with better structure and vegetation heterogeneity. The protected and unprotected areas hosted important records of endemic and/or threatened birds. We suggested some important places for implementation of new protected areas due to the larger concentrations of the target birds and because they are located within the boundaries of the Important Bird Areas.

    Productivity in the semi-arid area of Northeast Brazil is limited by nitrogen deficiency but fertilizers are not used due to the risk of this investment, usually calculated considering the year of application. Part of the fertilizer accumulates in the soil and can be used in subsequent crops. To provide information on accumulation, an experiment was established at Coxixola, city Pernambuco state consisting of combinations of single and intercropped corn and beans, with and without nitrogen fertilization (16 Kg.ha-1). Planting was done in holes, 1,1 x 1,0 m apart and 15N ammonium nitrate was applied in the there central holes of the plots. At harvest, plants in these hole were analysed separately and the soil was sampled at threre depths and five distances from the point of application of the fertilizer. Productivities were low, without differences between fertilized and non fertilized treatments for grain but with differences for straw. Single corn absorbed more (34%) and retained more of the N fertilizer in the soil (50%) than single beans (16 e 28%) and intercrop (corn 15% beans 11% soil 48%). Part of the unrecovered fertilizer may have migrated out of the sampled volume. This migration and the losses in beans indicate that only a small effect is expected for the accumulated N in the soil.

    Full Text Available Sheep production is present on all continents and has been practiced in Brazil since the colonization. In this study, the multitemporal dynamics of sheep production in Brazil is examined using official government data (Brazilian Institute for Geography and Statistics-IBGE from 1976 to 2010. Maps of flock growth rates and growth acceleration maps by municipality were elaborated. The Southern states are seen to show a reduction in production mainly due to the wool crisis in the 1970s and 80s. The Northeast is seen to be important for meat production. More recently, centerwest and northern states have shown an increase in growth rates but this is still incipient. The maps of growth, acceleration and midpoint for sheep production showed a noticeable return to an increase in production in the South in recent years. The midpoint of production flow was in the northeast direction, which has stagnated. There was great dynamics in sheep production over the whole Brazilian territory, which affected supply chains due to the expansion of domestic and foreign markets. Areas with higher fluctuations in production are more vulnerable in terms of investment policies.

    Full Text Available INTRODUCTION: In recent years, hantavirus infections producing severe diseases have obtained an increased attention from public health authorities from the countries of Eurasia to the Americas. Brazil has reported 1,300 cases of hantavirus cardiopulmonary syndrome (HCPS from 1993 to 2010, with about 80 of them occurring in the northeast of the State of São Paulo, with 48% fatality rate. Araraquara virus was the causative agent of HCPS in the region. Considering that hantaviruses causing human disease in the Americas were unknown until 1993, we have looked for hantavirus infections in the population of Cássia dos Coqueiros county, northeast of the State of São Paulo, Brazil, before this time. This county has about 2,800 inhabitants and an economy based on agriculture, including cultivation of Brachiaria decumbens grass. The grass seeds are an important rodent attraction, facilitating transmission of hantavirus to man. Four HCPS cases were reported so far in the county. METHODS: In this study, 1,876 sera collected from 1987 to 1990 were tested for IgG to hantavirus by IgG-ELISA, using the N recombinant protein of Araraquara virus as antigen. RESULTS: Positive results were observed in 89 (4.7% samples, which were all collected in 1987. The positivity among urban inhabitants was 5.3%, compared with 4.3% among those living in rural areas. CONCLUSIONS: Our results showed that hantavirus infections occurred in Cássia dos Coqueiros, completely unrecognized, even before hantaviruses were described in the Americas.

    Background Migration and urbanization are central to sustainable development and health, but data on temporal trends in defined populations are scarce. Healthy men and women migrate because opportunities for employment and betterment are not equally distributed geographically. The disruption can result in unhealthy exposures and environments and income returns for the origin household. Objectives The objectives of the paper are to describe the patterns, levels, and trends of temporary migration in rural northeast South Africa; the mortality trends by cause category over the period 2000–2011; and the associations between temporary migration and mortality by broad cause of death categories. Method Longitudinal, Agincourt Health and Demographic Surveillance System data are used in a continuous, survival time, competing-risk model. Findings In rural, northeast South Africa, temporary migration, which involves migrants relocating mainly for work purposes and remaining linked to the rural household, is more important than age and sex in explaining variations in mortality, whatever the cause. In this setting, the changing relationship between temporary migration and communicable disease mortality is primarily affected by reduced exposure of the migrant to unhealthy conditions. The study suggests that the changing relationship between temporary migration and non-communicable disease mortality is mainly affected by increased livelihood benefits of longer duration migration. Conclusion Since temporary migration is not associated with communicable diseases only, public health policies should account for population mobility whatever the targeted health risk. There is a need to strengthen the rural health care system, because migrants tend to return to the rural households when they need health care. PMID:24848656

    The atmospheric structure over north-east Brazil during anomalous rainfall years is studied in the 11 levels of the outputs of the Laboratoire de Météorologie Dynamique atmospheric general circulation model (LMD AGCM). Seven 19-year simulations were performed using observed sea-surface temperature (SST) corresponding to the period 1970- 1988. The ensemble mean is calculated for each month of the period, leading to an ensemble-averaged simulation. The simulated March-April rainfall is in good agreement with observations. Correlations of simulated rainfall and three SST indices relative to the equatorial Pacific and northern and southern parts of the Atlantic Ocean exhibit stronger relationships in the simulation than in the observations. This is particularly true with the SST gradient in the Atlantic (Atlantic dipole). Analyses on 200 ;hPa velocity potential, vertical velocity, and vertical integral of the zonal component of mass flux are performed for years of abnormal rainfall and positive/negative SST anomalies in the Pacific and Atlantic oceans in March-April during the rainy season over the Nordeste region. The results at 200 hPa show a convergence anomaly over Nordeste and a divergence anomaly over the Pacific concomitant with dry seasons associated with warm SST anomalies in the Pacific and warm (cold) waters in the North (South) Atlantic. During drought years convection inside the ITCZ indicated by the vertical velocity exhibits a displacement of the convection zone corresponding to a northward migration of the ITCZ. The east-west circulation depicted by the zonal divergent mass flux shows subsiding motion over Nordeste and ascending motion over the Pacific in drought years, accompanied by warm waters in the eastern Pacific and warm/cold waters in northern/southern Atlantic. Rainfall variability of the Nordeste rainfall is linked mainly to vertical motion and SST variability through the migration of the ITCZ and the east-west circulation.

    To evaluate the Rural Medical Scholars (RMS) Program's effectiveness to produce rural physicians for Alabama. A nonrandomized intervention study compared RMS (1997-2002) with control groups in usual medical education (1991-2002) at the University of Alabama School of Medicine's main and regional campuses. Participants were RMS and others admitted to regular medical education, and the intervention was the RMS Program. Measures assessed the percentage of graduates practicing in rural areas. Odds ratios compared effectiveness of producing rural Alabama physicians. The RMS Program (N = 54), regional campuses (N = 182), and main campus (N = 649) produced 48.1% (odds ratio 6.4, P rural physicians, respectively. The RMS Program, contrasted to other local programs of medical education, was effective in producing rural physicians. These results were comparable to benchmark programs in the Northeast and Midwest USA on which the RMS Program was modeled, justifying the assumption that model programs can be replicated in different regions. However, this positive effect was not shared by a disparate rural minority population, suggesting that models for rural medical education must be adjusted to meet the challenge of such communities for physicians. © 2017 National Rural Health Association.

  19. Prevalence and risk factors for porcine cysticercosis in rural communities of eastern Minas Gerais, Brazil

    Emilio C. Acevedo-Nieto

    Full Text Available ABSTRACT: Cysticercosis is caused by Taenia solium, a parasitic zoonosis that affects human and pigs raised free-range in developing countries. The epidemiology of the taeniosis cysticercosis complex in Brazil is poorly understood especially when it comes to field research. The aim of this study was to estimate the prevalence and identify the risk factors associated with porcine cysticercosis in rural communities located in the east of Minas Gerais (MG, Brazil. From 371 farms in the county of Tumiritinga/MG, 101 farms from 14 communities were randomly sampled. Blood samples from pigs were collected, and epidemiological questionnaires were carried out. The serum samples obtained were analyzed through immunodiagnosis techniques, including ELISA and Western Blot, both for the detection of antibodies. The data obtained by different surveys were analyzed using EpiInfo 3.5.1 software to determine seroprevalence and risk factors associated with cysticercosis. The prevalence of farms with porcine cysticercosis was 9.9% (10/101 and antibody-based seropositive was 5.3% (13/247. The results indicate that cysticercosis occurs in high level in the rural area never studied before. These results suggest the presence of tapeworm carriers contributing to the occurrence and maintenance of this zoonotic life cycle in the county. Regarding risk factors, the most significant determinants for porcine cysticercosis in the field were free-range pig management (OR: 17.4, p: 0.0001, the method of disposal of human faeces in the environmental (OR: 7.6; p 0.012, and the size of the farm. Porcine cysticercosis was diagnosed only in areas represented by Agrarian Reform Settlements. From the results, it is possible to recommend as a means of control and prevention the destination of human faeces in appropriate sanitary landfills and the production of pigs in an enclosed area. Additionally, improving education in the communities sampled will indirectly affect the spreading of

    Full Text Available This paper deals with suicide in rural areas of Rio Grande do Sul, Brazil, considering the relation of this phenomenon with the advance of the capitalism in the countryside. This change has been creating new living and working styles and, besides, processes which lead to illness. Among these processes, suicide becomes a reality as a process of self-destruction and self-exclusion. These are sociopathologies of the development which are created in demonstrations of mental illness, depression and suicides, driven by a model of development imposed in the rural area through the economic incentive and, also, through all the economic speech carrying a project of hope. It is about the social and economic systems acting as generators of precariousness, human, familiar and psycho-philosophical costs, desocialization processes, self-generated alienation and self-cleaving, showing that it is increasingly necessary to think about the relation between the social and the individual in life and death processes

Uma breve análise comparativa nos leva a deduzir que o modelo de desenvolvimento, nos três países, ainda prioriza a figura masculina no espaço agrícola, no que se refere à titularidade da terra, ao acesso à crédito e à aquisição de equipamentos ou outros recursos materiais. Sugere-se que, tanto em Cuba, um país socialista, como no México e Brasil, países capitalistas, os pressupostos das políticas sociais direcionadas para as trabalhadoras rurais devem levar em conta as necessidades básicas das mulheres camponesas para garantir um desenvolvimento mais humano e sustentávelThis article discusses different views about sustainable development, emphasizing - on the basis of a survey conducted in Brazil, Mexico, and Cuba - the role of rural women in food production and natural resource management, the strength of the rural women's movement in the conquest of rights, and the decisive participation of women in defining proposals for public policies that guarantee gender equality in rural areas. A brief comparative analysis leads us to conclude that the development model in the three countries still prioritizes the male figure in relation to land tenure, access to credit and purchase of equipment or other material resources. It is suggested that both in Cuba, a socialist country, and in Mexico and Brazil, capitalist countries, the assumptions of social policies directed to rural female workers should take into account the basic needs

    More than 95% of total energy produced in Brazil comes from highly efficient hydroelectric power plants but, faced with a serious shortage of energy after the year 2000, the country is now considering wind energy as one of the basic alternatives for energy supply. It is suggested that biomass, wind energy and biogas may be included in a future supply policy for the north-east region of the land. The structure of, the privatisation, legislation and the tariff system within the Brazilian power sector are described in addition to the present situation regarding wind energy in the country, including current and coming projects in this field, the excellent wind conditions in Northeastern Brazil and investment possibilities. The political activities in this field of the Danish Folkecenter for Renewable Energy are noted and future developments in Brazil are discussed. It is concluded that there are good prospects for Danish windmill technology on the Brazilian market. Wind measurement programs are presently being carried out in various areas of the country, though a number of impediments to the development of wind energy in Brazil remain. (AB)

    This article comprises geochemical, structural and radiometric investigations on radioactive pegmatites of the Borborema Pegmatitic Province in Northeast Brazil. The studied area is located in the surroundings of the city of Parelhas, in the geotectonic Province of Borborema. It is well known for its thousands of pegmatitic bodies exploited in primitive mines called garimpos. The main goal was to find an efficient, cheap and routine inspection procedure to identify the origin of commercialized radioactive columbite-tantalite (coltan) ore. The Brazilian Nuclear Energy Agency (CNEN) controls uranium commerce and nuclear activity in Brazil. Without an effective method to characterize coltan ores from different localities it is impossible to control the trade. The here presented new method was developed by correlating structural features of these pegmatites with the geochemical behavior of their coltan samples. It was found that the variation of U/Th vs. Nb 2 O 5 /Ta 2 O 5 provides geochemical signatures (analytical fingerprints) for the source location of such ore. The new method was tested with coltan samples of commercial batches from the Brazilian states of Amapa and Rondonia and also generated distinct geochemical signatures. A radiometric survey (CPS) to study the environmental impact of gamma radiation was also carried out in several mines and pegmatites. It included in situ measurements of pegmatite walls, enclosing rocks, soil, and accumulated water and revealed that gamma emitters are hardly solubilized and therefore environmental gamma radiation generally is not enhanced to a dangerous level.

    Excessive exposure to the sun during childhood is strongly associated with the development of skin cancer in the future. The only way to prevent the development of skin cancer is to protect against ultraviolet radiation, which can be achieved through strategic awareness during childhood and adolescence. The aim of this work was to evaluate the impact of educational activities for rural and urban students to promote the use of sunscreens and prevent skin cancer. This study was carried out with students (9-12 years) of rural (n=70) and urban (n=70) schools in Rio Grande do Sul state, Brazil. The educational interventions were lectures and games. The impact of this strategy was evaluated through the application of a questionnaire before and after the interventions. Before the intervention, it was found around 50% of rural and urban students were not aware of the damage caused by sun exposure, often exposing themselves to UV radiation without use sunscreen ( ~ 25 %) and at the most critical times of the day/year. After the lectures we observed an improvement in the behavior of the students with regard to sun exposure and knowledge about skin cancer. The results of this study emphasize the importance of prevention strategies for skin cancer and promoting the use of sunscreens based educational strategies. The interventions were of great value in relation to disseminating knowledge on the subject.

    Photosynthetically active solar radiation, known by its acronym in the English language as PAR, is the principal driving force of innumerable biological and physical processes related to biomass production, such as, the evolution of vegetal covering, agricultural productivity, and countless environment aspects, among others. Unfortunately in Brazil and particularly in the Northeast of Brazil, the PAR radiation measures are not a routine part of meteorological station measures, and therefore are still rarer than solar irradiation measures. In this context, a station was installed in Recife, Pernambuco in 2003, to carry out simultaneous measures of daily solar irradiation and PAR irradiation, which permits the modelling and valuation of the relationship between these two parameters and thus makes the estimation of PAR radiation possible, where there used to be only information on solar irradiation. Three others stations are being installed, one on Fernando de Noronha-PE, another in Pesqueira-PE, and the other in Xingo-SE, which complete a group of 4 between Latitudes 8 deg and 10 deg South and Longitudes 34 deg to 38 deg West, each having differentiated Equatorial Climates: island maritime, continental maritime, sylvan (Agreste) and semi-arid.

    The Earth's crust may have different levels of natural radioactivity as a consequence of the different types of minerals that form its composition. Exploration activities of natural sources may have a high radiometric impact for the radionuclides of the natural series and contributes to radionuclides transitions to others areas. The distribution of natural radioactive elements 226 Ra, 232 Th, and 40 K in rock and soil is not uniform and as a consequence all building materials contain amounts of natural radioactive substances. This study aimed to establish the calculation of the Equivalent Radium Activity (Ra Eq ) in brickwork's clays in the adjacent area to the uranium deposits in Northeast Brazil cities in the states of Paraiba and Rio Grande do Norte. The analyses were performed using the non-destructive method HPGe-Be gamma spectrometry. Twenty-eight samples were collected from ten brickworks in the cities of Sao Jose do Sabugi and Santa Luzia, in Paraiba State and Santana do Serido and Parelhas, in Rio Grande do Norte State. The activities of RaEq ranged from 84.5 to 747.8 Bq/kg with an average of 334.0 Bq/kg. Approximately 29% of the analyzed samples had activities of RaEq above the limit defined by UNSCEAR (the limit is 370 Bq/kg), where the clays must have its sources of extraction monitored, respecting the radioecological protection rules. From the qualification of the samples, it has been certified that the radionuclides present in this study are exclusively of natural origin. (author)

    The Banco Nacional de Desenvolvimento Economico e Social - BNDES, a Brazilian bank for the economic and social development - worried about the high connections costs practiced by the energy utilities, made some demands to the Sao Paulo State Government, Brazil to become the agent backer of the rural electrification 'Luz da Terra' program. Two of them was the elaboration and adoption of an unified technical norm privileging the adoption of simplified systems of electric energy distribution and an only system of costs establishment compatible with the goals of low medium connection costs for the state. A model of costs establishment was elaborated through the medium prices of market materials and labor activities whose values were more significant in the final composition of the projects. The model was accepted by the utilities participants of the program as a pattern to establish a reference cost for each project to be executed. The advantage of an unified system is that it allows to each project of grid extension to have its costs of materials and labor activities estimated in the same base, independent of the company involved. In spite of not having been adopted by all the utilities ones, the adoption of an unified system and the establishment of reference costs was essential for the control of rural distribution grids prices in the Sao Paulo State.

    Full Text Available Northeast China is located in a high latitude area of the world and undergoes a cold season that lasts six months each year. Recently, regional haze episodes with high concentrations of fine particles (PM2.5 have frequently been occurring in Northeast China during the heating period, but little information has been available. Aerosol particles were collected in winter at a site in a suburban county town (T1 and a site in a background rural area (T2. Morphology, size, elemental composition, and mixing state of individual aerosol particles were characterized by transmission electron microscopy (TEM. Aerosol particles were mainly composed of organic matter (OM and S-rich and certain amounts of soot and K-rich. OM represented the most abundant particles, accounting for 60.7% and 53.5% at the T1 and T2 sites, respectively. Abundant spherical OM particles were likely emitted directly from coal-burning stoves. Soot decreased from 16.9% at the T1 site to 4.6% at the T2 site and sulfate particles decrease from 35.9% at the T2 site to 15.7% at the T1 site, suggesting that long-range transport air masses experienced more aging processes and produced more secondary particles. Based on our investigations, we proposed that emissions from coal-burning stoves in most rural areas of the west part of Northeast China can induce regional haze episodes.

    In the 1980s, an increase in mortality rates for prostate cancer was observed in North America and developed European countries. In the 1990s, however, mortality rates decreased for these countries, an outcome related to early detection of the disease. Conversely, an upward trend in mortality rates was observed in Brazil. This study describe the trends in mortality for prostate cancer in Brazil and geographic regions (North, Northeast, South, Southeast, and Central-West) between 1980 until 2014 and analyze the influence of age, period, and cohort effects on mortality rates. This time-series study used data from the Mortality Information System (SIM) and population data from Brazilian Institute for Geography and Statistics (IBGE). The effects on mortality rates were examined using age-period-cohort (APC) models. Crude and standardized mortality rates showed an upward trend for Brazil and its regions more than 2-fold the last 30 years. Age effects showed an increased risk of death in all regions. Period effects showed a higher risk of death in the finals periods for the North and Northeast. Cohort effects showed risk of death was higher for younger than older generations in Brazil and regions, mainly Northeast (RR Adjusted =3.12, 95% CI 1.29-1.41; RR Adjusted =0.28, 95% CI 0.26-0.30, respectively). The increase in prostate cancer mortality rates in Brazil and its regions was mainly due to population aging. The differences in mortality rates and APC effects between regions are related to demographic differences and access of health services across the country. Copyright © 2017 Elsevier Ltd.

    A. Vasconcellos

    Full Text Available Dinoponera quadriceps is a queenless neotropical ponerinae ant. Nest spacing and abundance were investigated in a remnant of the Atlantic forest in Northeast Brazil. Males were captured with a light trap between August 1994 and July 1996. Nest density varied from 15 to 40 ha-1. An overdispersion of nests suggests that the intraspecific competition may be an important factor regulating their spatial arrangement. Territory size was correlated with worker population size of the colonies. The nests had up to 16 chambers, with variations in their architecture closely related to habitat diversification. Populations varied from 12 to 97 adult workers per nest, with a mean density of 1,618 workers ha-1 and a live biomass of 461 g ha-1 (n = 13 nests. Males swarm continually throughout almost all months of the year, suggesting that production and swarming are more influenced by mechanisms that regulate the sexual activity of workers than by climatic factors.

    Full Text Available Abstract Objectives: to analyze possible associations between Specific Hypertensive Gestation Syndrome (SHGS and sociodemographic, prenatal, and delivery characteristics of young adult and teenage mothers. Methods: a hospital-based cross-sectional study and regional level, gathered from 54 municipalities in the Northeast region of Brazil from 2011-2012, using records from the National Survey, "Born in Brazil". A theoretical conceptual model with three-level hierarchy was established, with SHGS being the outcome variable. A multivariate analysis was performed from the bivariate analysis and p-value, with a significance of < 0.2 by the Wald test. Results: of the 2,960 adolescents and young adults included in the study, 135 (4.6% developed HSP. The mothers without a partner had 50% (OR=1.53 greater chance of presenting this pathology; while those without adequate schooling for age presented 90% higher chance (OR = 1.86 and those with a prior clinical risk factor, the chance of presenting the outcome was 21 times the chance of those without this antecedent (OR = 21.72. Conclusions: significant associations were identified between SHGS and postpartum adolescents and young adults without a partner, with low schooling and prior clinical risk, signaling the importance of investments in the quality of prenatal care and labor of the most vulnerable groups.

    Full Text Available OBJETIVO: Descrever comportamentos facilitadores à exposição ao HIV/Aids em população rural. MÉTODOS: Pesquisa qualitativa realizada com 52 pacientes atendidos em ambulatório de DST/Aids, em 2002-2003. Foram feitas entrevistas abertas e semi-estruturadas em profundidade com os participantes (30 homens e 22 mulheres, conduzidas no ambulatório ou em suas residências, em municípios rurais da região norte de Minas Gerais. As entrevistas foram transcritas, analisadas em categorias: concepções da doença, trabalho, sociabilidade, informações prévias sobre a doença, modo de vida. A interpretação dos resultados baseou-se na análise de conteúdo. RESULTADOS: Na percepção dos entrevistados, a Aids era "doença de cidade grande" e de "forasteiro", desvinculada da cultura local. Todos os entrevistados se infectaram através de atividades heterossexuais ou homossexuais. A migração rural-urbana é aspecto relevante da infecção do HIV na região devido ao deslocamento em busca de trabalho. CONCLUSÕES: As noções populares de doença contribuem para vulnerabilidade à infecção pelo HIV. É necessário apreender noções culturais locais para melhor entender as categorias de pensamento dessa população, enfocando essas noções ao divulgar informações sobre a doença.OBJECTIVE: To describe behaviors facilitating HIV/AIDS exposure in rural population.

    Full Text Available INTRODUCTION: Rodent-borne hantaviruses cause severe human diseases. We completed a serological survey of hantavirus infection in rural inhabitants of Turvo County, in the southern State of Santa Catarina, Brazil, in which seropositivity for hantavirus was correlated to previous disease in the participants. METHODS: The levels of IgG antibodies to hantavirus Araraquara in the sera of 257 individuals were determined using an immunoenzymatic assay. RESULTS: IgG antibodies to hantavirus were found in 2.3% of the participants. All seropositive participants reported previous disease with symptoms suggestive of hantavirus cardiopulmonary syndrome. CONCLUSIONS: Human infections causing unreported cardiopulmonary syndrome probably occur in the southern State of Santa Catarina.

In order to contribute with the process of diffusion of writing practices in the bahian rural society in the threshold of the non census period , by the critical application of what is called “method of the computation of signatures” to documental sources produced by the Law of Lands (1850. The results show that the ability of that type of proprietors in the documentation is relatively high in the cities we´ve investigated: Itapicuru, 86,36%, Tucano, 50,80%, and Bom Conselho, 45,91%. This is a different result if we´re comparing to the remaining population shown in the Census of 1872, once it seems to indicate a specific group, with ownerships, representing a specialization of writing ability and, also, texts mostly written by men (64,08%. Those sources include part of the rural population, specifically the proprietors of lands, and offer an approximate census survey of the ability to write signatures in the context of the regulation of lands. The main objective is to contribute with the history of the Portuguese language in the inland of Bahia, through one of the ways proposed by Houaiss (1985, the penetration of the written language in Brazil.

    The government of India is promoting and increasing investment in the traditional medicine systems of Ayurveda, Yoga, Unani, Siddha and Homeopathy (AYUSH) in the northeast region of India. But there are few empirical data that support this policy decision. This study estimates the awareness and use of the different medical systems in rural Meghalaya, a state in north-east India with a predominantly ethnic tribal population. We conducted a cross-sectional multistage random sample household survey across all districts of Meghalaya. To enable appropriate estimates for the whole of rural Meghalaya, the data were weighted to allow for the probability of selection of households at each stage of the sampling process. Both local tribal medicine and biomedicine were widely accepted and used, but the majority (68.7%, 95% CI: 51.9-81.7) had not heard of AYUSH and even fewer had used it. Tribal medicine was used (79.1%, 95% CI 66.3-88.0), thought to be effective (87.5%, 95% CI: 74.2-94.1) and given in a variety of disorders, including both minor and major diseases. In the 3 months prior to the survey, 46.2% (95% CI: 30.5-62.8) had used tribal medicine. Only 10.5% (95% CI: 6.1-17.6) reported ever using any of the AYUSH systems. Our comparative estimates of the awareness and use of tribal medicine, different systems of AYUSH and of biomedicine among indigenous populations of India question the basis on which AYUSH is promoted in the northeast region of India and in the state of Meghalaya in particular. © 2015 John Wiley & Sons Ltd.

    This article comprises geochemical, structural and radiometric investigations on radioactive pegmatites of the Borborema Pegmatitic Province in Northeast Brazil. The studied area is located in the surroundings of the city of Parelhas, in the geotectonic Province of Borborema. It is well known for its thousands of pegmatitic bodies exploited in primitive mines called garimpos. The main goal was to find an efficient, cheap and routine inspection procedure to identify the origin of commercialized radioactive columbite-tantalite (coltan) ore. The Brazilian Nuclear Energy Agency (CNEN) controls uranium commerce and nuclear activity in Brazil. Without an effective method to characterize coltan ores from different localities it is impossible to control the trade. The here presented new method was developed by correlating structural features of these pegmatites with the geochemical behavior of their coltan samples. It was found that the variation of U/Th vs. Nb{sub 2}O{sub 5}/Ta{sub 2}O{sub 5} provides geochemical signatures (analytical fingerprints) for the source location of such ore. The new method was tested with coltan samples of commercial batches from the Brazilian states of Amapa and Rondonia and also generated distinct geochemical signatures. A radiometric survey (CPS) to study the environmental impact of gamma radiation was also carried out in several mines and pegmatites. It included in situ measurements of pegmatite walls, enclosing rocks, soil, and accumulated water and revealed that gamma emitters are hardly solubilized and therefore environmental gamma radiation generally is not enhanced to a dangerous level.

    Full Text Available Schistosomiasis mansoni in the Serrano village, municipality of Cururupu, state of Maranhão, Brazil, is a widely spread disease. The PECE (Program for the Control of Schistosomiasis, undertaken since 1979 has reduced the prevalence of S. mansoni infection and the hepatosplenic form of the disease. Nevertheless piped water is available in 84% of the households, prevalence remains above 20%. In order to identify other risk factors responsible for the persistence of high prevalence levels, a cross-sectional survey was carried out in a systematic sample of 294 people of varying ages. Socioeconomic, environmental and demographic variables, and water contact patterns were investigated. Fecal samples were collected and analyzed by the Kato-Katz technique. Prevalence of S. mansoni infection was 24.1%, higher among males (35.5% and between 10-19 years of age (36.6%. The risk factors identified in the univariable analysis were water contacts for vegetable extraction (Risk Ratio - RR = 2.92, crossing streams (RR = 2.55, bathing (RR = 2.35, fishing (RR = 2.19, hunting (RR = 2.17, cattle breeding (RR = 2.04, manioc culture (RR = 1.90 and leisure (RR = 1.56.

    Leishmaniasis is a parasitic disease found in the continents of Europe, Asia, Africa and the Americas. In Brazil, the disease is an important public health problem, occurring in most states, but mainly in the Northeast region of the country, with the state of Alagoas having a significant number of confirmed cases. The present study establishes and discusses the epidemiological profile of cases of leishmaniases treated at the Reference Center of Alagoas, Hospital Escola Hélvio de Farias Auto, between January 2000 and October 2008. During this period, records of 2,104 patients notified to the hospital Epidemiological Surveillance Center were reviewed. The epidemiology of leishmaniasis, both visceral and tegumentary, has shown a profile that has changed over throughout the years, with a decrease in the number of notified cases. Disease occurrence was associated with lower social economic classes, and affected mainly rural workers in general, housewives and students.

    To assess the number of children born with microcephaly in the State of Paraíba, north-east Brazil. We contacted 21 maternity centres belonging to a paediatric cardiology network, with access to information regarding more than 100 000 neonates born between 1 January 2012 and 31 December 2015. For 10% of these neonates, nurses were requested to retrieve head circumference measurements data from delivery-room books. We used three separate criteria to classify whether a neonate had microcephaly: (i) the Brazilian Ministry of Health proposed criterion: term neonates (gestational age ≥ 37 weeks) with a head circumference of less than 32 cm; (ii) Fenton curves: neonates with a head circumference of less than -3 standard deviation for age and gender; or (iii) the proportionality criterion: neonates with a head circumference of less than ((height/2))+10) ± 2. Between 1 and 31 December 2015, nurses obtained data for 16 208 neonates. Depending on which criterion we used, the number of neonates with microcephaly varied from 678 to 1272 (4.2-8.2%). Two per cent (316) of the neonates fulfilled all three criteria. We observed temporal fluctuations of microcephaly prevalence from late 2012. The numbers of microcephaly reported here are much higher than the 6.4 per 10 000 live births reported by the Brazilian live birth information system. The results raise questions about the notification system, the appropriateness of the diagnostic criteria and future implications for the affected children and their families. More studies are needed to understand the epidemiology and the implications for the Brazilian health system.

    1983-01-01

    In the first part of this paper palaeomagnetic and rock magnetism investigations were developed in volcanic samples from the Northeast of Brazil. The age of the samples spans the Jurassic and Cretaceous periods. To accomplish this task four areas were studied and a total of 495 samples from 58 sites were analysed. A portable drilling machine with 2.5 em core diameter was used to collect the samples. The orientation of the samples were obtained by means of a magnetic compass, and a clinometer. The analysis of the magnetic minerals of these samples was done by thermomagnetic curves and by X-ray diffraction. In most cases the magnetic phase in the rocks is mainly titanomagnetite with poor titanium content. Maghemite and sometimes hematite, usually a product of weathering, did not obscure the initial thermoremanent magnetization of these rocks. The second part of this paper deals with the determination of the time of the opening of the South Atlantic ocean by means of palaeomagnetic data. In this paper, however, instead of using the polar wandering paths of the continents (the usual method) statistical tests were applied that give the probability that a certain configuration for the two continents be consistent or not with the palaeomagnetic data for a chosen period.

    To assess the kind and frequency of sensitisation to aeroallergens (skin prick test - SPT) of asthmatic and non-asthmatic adolescents (13-14 years old) living in the city of Caruaru, Northeast of Brazil, and to analyse their exposure to some environmental factors. A case-control study was conducted with asthmatic (50) and non-asthmatic (150) adolescents diagnosed by the International Study of Asthma and Allergies in Childhood (ISAAC) written questionnaire. All were submitted to SPT with aeroallergens (house dust mites, cat and dog epithelium, cockroaches, moulds and grass) and completed a questionnaire to evaluate their environmental exposure. There were no significant differences between groups regarding gender, age, number of siblings and environmental exposure. Asthmatic subjects exhibited a higher frequency of positive SPTs than non-asthmatic subjects (54.0% vs 33.3%, p=0.009) mainly due to Periplaneta americana (34.0% vs 12.7%, p=0.0007 respectively) and Canis familiaris (20.0% vs 8.7%, p=0.029). Although sensitisation to aeroallergens was high among non-asthmatic adolescents, asthma was associated with parental history of atopic disease and sensitisation to P. americana and Canis familiaris but not to D. pteronyssinus showing that local studies are mandatory for the tailoring of appropriate management of allergic diseases.

    Artisanal fishery is one of the most important economic activities for human populations living in coastal areas. The traditional knowledge that fishermen have of fishes is of utmost importance for the establishment of conservation strategies for many species. This study aimed to analyse the knowledge of and utilization of fishes by the artisanal fishermen in a fishing community on the coast of Ceará State (Northeast Brazil). In 2011, a number of semi-structured interviews were performed with fishermen with more than 20 years of fishery experience. The interviews were about fisheries (collecting spots, artefacts, etc.) and fish use. The fishes cited by the fishermen were identified scientifically and ethnotaxonomically. Considered masters of fishery, they cited 162 vernacular names of fishes, which corresponded to 290 different species, also including other animals such as dolphins, porpoises, whales and manatees. The criteria for the classification of the fishes were well known and utilised by the fishermen, and they were based on morphology, behaviour, habitat and the importance of commercial and fishing activities. Four hierarchical categories were identified in their classification system: kingdom, life-form, generic and specific. The fish nomenclature created by the fishermen was mostly composed of generic and monotypic names. The main uses of fish were for food and commercial purposes. The results stress the richness and complexity of the knowledge of the artisanal fishermen of Redonda Beach, and they provide support for the possibility of future studies and for the development of management plans and the management of wildlife resources.

    Carvalho, Taiana Silva; Pellanda, Lucia Campos; Doyle, Pat

    Brazil is a large, heterogeneous, and diverse country, marked by social, economic, and regional inequalities. Stillbirth is a global concern, especially in low- and middle-income countries. This study investigated the prevalence and possible determinants of stillbirth in different regions of Brazil. This is a cross-sectional study including all women of reproductive age who had had a pregnancy in the last five years, enrolled in the most recent Brazilian Demographic and Health Survey (DHS/PNDS-2006/07). Logistic regression was used to assess the association between region and other maternal characteristics and stillbirth risk. The prevalence of stillbirth in Brazil was 14.82 per 1000 births, with great variation by region of the country, and a higher prevalence among the most deprived. The North and Northeast regions had the highest odds of stillbirth compared to the Center-West, which persisted after adjustment for multiple confounders - including deprivation level and ethnicity. Low maternal age and maternal obesity were also related to higher odds of stillbirth. In Brazil, the region influences stillbirth risk, with much higher risk in the North and Northeast. Variation in socioeconomic level does not explain this finding. Further research on the subject should explore other possible explanations, such as antenatal care and type of delivery, as well as the role of the private and public health systems in determining stillbirth. Preventive strategies should be directed to these historically disadvantaged regions, such as guaranteeing access and quality of care during pregnancy and around the time of birth.

    Poverty is intrinsically related to the incidence of Neglected Tropical Diseases (NTDs). The main countries that have the lowest human development indices (HDI) and the highest burdens of NTDs are located in tropical and subtropical regions of the world. Among these countries is Brazil, which is ranked 70th in HDI. Nine out of the ten NTDs established by the World Health Organization (WHO) are present in Brazil. Leishmaniasis, tuberculosis, dengue fever and leprosy are present over almost the entire Brazilian territory. More than 90% of malaria cases occur in the Northern region of the country, and lymphatic filariasis and onchocerciasis occur in outbreaks in a particular region. The North and Northeast regions of Brazil have the lowest HDIs and the highest rates of NTDs. These diseases are considered neglected because there is not important investment in projects for the development of new drugs and vaccines and existing programs to control these diseases are not sufficient. Another problem related to NTDs is co-infection with HIV, which favors the occurrence of severe clinical manifestations and therapeutic failure. In this article, we describe the status of the main NTDs currently occurring in Brazil and relate them to the HDI and poverty.

    Coccidioidomycosis is an endemic infection with a relatively limited geographic distribution: Mexico, Guatemala, Honduras, Colombia, Venezuela, Bolivia, Paraguay, Argentina and the southwest of the United States. In these countries, the endemic area is restricted to the semiarid desert like regions which are similar to the northeast of Brazil. The patient is a 32 year-old male, born in the state of Bahia (Northeast of Brazil) and has been living in São Paulo (Southeast) for 6 years. He was admitted at Hospital das Clínicas, at the Department of Pneumology in October 1996, with a 6 month history of progressive and productive cough, fever, malaise, chills, loss of weight, weakness and arthralgia in the small joints. Chest x-rays and computerized tomography disclosed an interstitial reticulonodular infiltrate with a cavity in the right upper lobe. The standard potassium hydroxide preparation of sputum and broncoalveolar lavage demonstrated the characteristic thickened wall spherules in various stages of development. Sabouraud dextrose agar, at 25 degrees C and 30 degrees C showed growth of white and cottony aerial miceleium.

    Background The objectives were to estimate the prevalence of hepatitis A among children and adolescents from the Northeast and Midwest regions and the Federal District of Brazil and to identify individual-, household- and area-levels factors associated with hepatitis A infection. Methods This population-based survey was conducted in 2004–2005 and covered individuals aged between 5 and 19 years. A stratified multistage cluster sampling technique with probability proportional to size was used to select 1937 individuals aged between 5 and 19 years living in the Federal capital and in the State capitals of 12 states in the study regions. The sample was stratified according to age (5–9 and 10- to 19-years-old) and capital within each region. Individual- and household-level data were collected by interview at the home of the individual. Variables related to the area were retrieved from census tract data. The outcome was total antibodies to hepatitis A virus detected using commercial EIA. The age distribution of the susceptible population was estimated using a simple catalytic model. The associations between HAV infection and independent variables were assessed using the odds ratio and corrected for the random design effect and sampling weight. Multilevel analysis was performed by GLLAMM using Stata 9.2. Results The prevalence of hepatitis A infection in the 5–9 and 10–19 age-group was 41.5 and 57.4%, respectively for the Northeast, 32.3 and 56.0%, respectively for the Midwest and 33.8 and 65.1% for the Federal District. A trend for the prevalence of HAV infection to increase according to age was detected in all sites. By the age of 5, 31.5% of the children had already been infected with HAV in the Northeast region compared with 20.0% in the other sites. By the age of 19 years, seropositivity was ∼70% in all areas. The curves of susceptible populations differed from one area to another. Multilevel modeling showed that variables relating to different levels of

    Recently, the booming rural tourism in endemic areas of the state of Minas Gerais was identified as a contributing factor in the dissemination of the infection with Schistosoma mansoni. This article presents data from six holiday resorts in a rural district approximately 100 km distant from Belo Horizonte, MG, Brazil, where a possibly new and until now unperceived way of transmission was observed. The infection takes place in swimming pools and little ponds, which are offered to tourists and the local population for fishing and leisure activities. The health authorities of the district reported cases of schistosomiasis among the local population after visiting these sites. As individuals of the non-immune middle class parts of the society of big urban centers also frequent these resorts, infection of these persons cannot be excluded. A malacological survey revealed the presence of molluscs of the species Biomphalaria glabrata and Biomphalaria straminea at the resorts. The snails (B. glabrata) of one resort tested positive for S. mansoni. In order to resolve this complex problem a multidisciplinary approach including health education, sanitation measures, assistance to the local health services, and evolvement of the local political authorities, the local community, the tourism association, and the owners of the leisure resorts is necessary. This evidence emphasizes the urgent need for a participative strategic plan to develop the local tourism in an organized and well-administered way. Only so this important source of income for the region can be ensured on the long term without disseminating the disease and putting the health of the visitors at risk.

    It is a transverse study where a questionnaire of alimentary frequency was applied (QAF) in 150 adults resident of the rural area of the city of Ibatiba (ES, Brazil). QAF classified the alimentary consumption as: habitual (>4 times in the week), not habitual (chayote, carrot, beet, pumpkin, juice of fruits, banana, orange, guava, mango and tangerine. It can be concluded that the feeding habit presented by the studied population it can come to increase in a medium or long period the prevalence and occurrences of chronic-degenerative diseases as hypertension, diabetes, obesity and coronary diseases. The alimentary consumption of this population needs concern, because when compared with the national patterns, it is observed some inadequacies, and it is known that this picture comes to every day causing damages the public health.

    Full Text Available Injuries caused by venomous animals reported by the agricultural workers from the municipality of Cuité, Curimataú region of Paraiba State, Northeast of Brazil, and the practices of folk medicine which they use to treat these cases were studied in this work from June to August 2010. The farmers studied aged from 11 to 90 years. The number of people who reported cases of injury by these animals in their families was high (89.3%. Scorpions, wasps, bees and snakes were the most cited and the extremities of the body (hands, feet, legs and head were the most affected. The practice of folk medicine to treat these injuries includes various procedures ranging from ritualistic treatments, use of animals or parts of them, and some herbal preparations. The folk treatment was reported as effective by most of the workers injured (63.9%. Body parts of dead snakes are used in various zootherapic treatments. In the imaginary of the agricultural workers the venomous animals are considered hazardous (48.7% or disgusting (11.3%, and several parts of such animals as the rattle, bee sting or snake leather are used as amulet. Several legends have also been reported about snakes, scorpions and bees. The need for educational activities that aim to clarify these workers about the dangers of such practices is urgent.

    Full Text Available The paper presents the results of an experimental process designed for the treatment of the sewage generated by a rural community located in the north-east of Brazil. The process consists of a preliminary mechanical treatment adopting coarse screens and grit traps, followed by a biological treatment in a UASB reactor and a sub-surface horizontal flow phytodepuration step. The use of a UASB reactor equipped with a top cover, as well as of the phytodepuration process employing a porous medium, showed to present important health advantages. In particular, there were no significant odor emissions and there was no evidence of the proliferation of insects and other disease vectors. The plant achieved the following mean abatement efficiencies: 92.9% for BOD5, 79.2% for COD and 94% for Suspended Solids. With regard to fecal indicators average efficiencies of 98.8% for fecal coliforms and 97.9% for fecal enterococci were achieved. The UASB reactor showed an important role in achieving this result. The research was also aimed at evaluating the optimal operating conditions for the UASB reactor in terms of hydraulic load and organic volumetric loading. The achieved results hence indicated that the process may be highly effective for small rural communities in tropical and sub-tropical areas.

    Studies about mental disorders are very rare in the Northeast of Brazil, especially when psychopathologies in children and adolescents are considered. The consequence is a small availability of data and an absence of a real epidemiological profile. This is a systematic review with meta-analysis, following the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) protocol, in the period from 2003 to 2015, using the databases LILACS, SciELO and BVS. The analysis comprised the keywords 'models of primary and secondary healthcare in mental health', 'psychiatric reform' and 'policies and services in mental health', using the Boolean operator '# AND'. Original texts based on secondary data from the Hospital Information System of the Brazilian Unified Health System were also included via the Citizen Electronic Record System, Instituto Brasileiro de Geografia e Estatística, and Ministry of Health. Grey literature was used by means of hand searching. A combined analysis of the strategies mentioned in the analyzed articles shows a combined odds ratio of 1.291 (confidence interval (CI) = 1.054-1.582), thus it demonstrates the efficacy of using such strategies in the elaboration of institutional apparatus in mental health. The p-value of the chi-square distribution resulted in .9753, which does not reject the hypothesis of association between strategies in mental health and possible development of institutional apparatus in mental health. A combined analysis of all strategies mentioned in the analyzed studies shows efficacy of using strategies to elaborate institutional apparatus in mental health.

    This work aimed to assess the clonal distribution among 94 strains of Staphylococcus aureus isolated from cow's milk, raw cheese, and a milking machine in 12 dairy farms in northeast Brazil, by analyzing different typing methods and detecting resistance and toxigenic profiles. For the first time, isolates of this region were assessed simultaneously by the polymorphism of the 3'-end coa gene and 16S-23S rDNA, pulsed-field gel electrophoresis, antibiotic resistance phenotyping, and toxigenic arsenal. Although pulsed-field gel electrophoresis patterns showed a wider variation (discriminatory index 0.83) than the PCR-based methods, the internal transcribed spacer-PCR proved to be a useful and inexpensive procedure for conducting epidemiological surveys of S. aureus on a regional scale. Each dairy farm had its own resistance profile, and in two herds, 63% of the strains were multiresistant, probably due to the indiscriminate use of antibiotics in bovine mastitis treatment. No methicillin-resistant S. aureus strains were detected in this study; however, 93.6% of S. aureus strains harbored variable profiles of staphylococcal enterotoxin genes seg, seh, sei, and sej. Transcriptional analysis revealed that 53.3% of staphylococcal enterotoxin genes actually transcribed, pointing out the food poisoning risk of these dairy products to consumers in the region. Based on the detection of the most prevalent clones in a herd or region, appropriate antibiotic therapy and specific immunization can be used for the treatment and control of staphylococcal mastitis.

    Mastitis is the principal disease affecting dairy herds worldwide. The aim of the present study was to characterize phenotypic and genotypic features associated with resistance to antimicrobials in Staphylococcus spp. isolated from 2064 milk samples of 525 lactating cows in the Northeast of Brazil. Of the 218 isolates analyzed, 57.8% were characterized as Staphylococcus aureus, 28% as coagulase-positive staphylococci other than S. aureus (oCPS), and 14.2% as coagulase-negative staphylococci (CNS). The test for susceptibility to antimicrobials showed amoxicillin (32.6%) to be the less effective drug in vitro, and the multi-drug resistance (MDR) rate for beta-lactams varied from 0 to 0.75. The genotypic characterization showed that 93.1% of the samples were tested positive for the blaZ gene, while none amplified mecA. The antibiotic efflux mechanism was observed in 0.9% of isolates. The biofilm formation was found in 3.7 and 96.3% of samples, respectively, on Congo red agar and on the microplate adhesion test, while the icaD gene was present in 92.2% of Staphylococcus spp. The high frequency of blaZ gene observed in this study was associated with the resistance of most Staphylococcus spp. to one or more of the beta-lactams tested, which are routinely used in Brazilian herds for mastitis treatment. The biofilm formation was also detected in the isolates analyzed being an important characteristic for pathogenicity and antimicrobial resistance of bacteria.

    Full Text Available Critical to the design and assessment of interventions for enteropathy and its developmental consequences in children living in impoverished conditions are non-invasive biomarkers that can detect intestinal damage and predict its effects on growth and development. We therefore assessed fecal, urinary and systemic biomarkers of enteropathy and growth predictors in 375 6-26 month-old children with varying degrees of malnutrition (stunting or wasting in Northeast Brazil. 301 of these children returned for followup anthropometry after 2-6m. Biomarkers that correlated with stunting included plasma IgA anti-LPS and anti-FliC, zonulin (if >12m old, and intestinal FABP (I-FABP, suggesting prior barrier disruption; and with citrulline, tryptophan and with lower serum amyloid A (SAA (suggesting impaired defenses. In contrast, subsequent growth was predicted in those with higher fecal MPO or A1AT and also by higher L/M, plasma LPS, I-FABP and SAA (showing intestinal barrier disruption and inflammation. Better growth was predicted in girls with higher plasma citrulline and in boys with higher plasma tryptophan. Interactions were also seen with fecal MPO and neopterin in predicting subsequent growth impairment. Biomarkers clustered into markers of 1 functional intestinal barrier disruption and translocation, 2 structural intestinal barrier disruption and inflammation and 3 systemic inflammation. Principle components pathway analyses also showed that L/M with %L, I-FABP and MPO associate with impaired growth, while also (like MPO associating with a systemic inflammation cluster of kynurenine, LBP, sCD14, SAA and K/T. Systemic evidence of LPS translocation associated with stunting, while markers of barrier disruption or repair (A1AT and Reg1 with low zonulin associated with fecal MPO and neopterin. We conclude that key noninvasive biomarkers of intestinal barrier disruption, LPS translocation and of intestinal and systemic inflammation can help elucidate how

    Full Text Available OBJECTIVE: The objective of this study was to identify the factors associated with exclusive breastfeeding in children aged less than six months from the Brazilian Legal Amazon and Northeast regions. METHODS: The study used data from a survey that assessed prenatal and infant (<1 year care in 2010. Sociodemographic, prenatal, delivery, and puerperium care factors with p<0.05 in multivariate analysis were associated with exclusive breastfeeding. RESULTS: For both regions, the prevalence of exclusive breastfeeding decreased with age, which was the main variable associated with early weaning. In the Legal Amazon, exclusive breastfeeding prevailed among: mothers aged 35 years or more; mothers living in state capitals; and mothers who breastfed on the first hour of life. In the Northeast, the probability of exclusive breastfeeding was greater for mothers aged 35 years or more. CONCLUSION: The factors associated with exclusive breastfeeding were child's and mother's age in both regions; and residence location and breastfeeding in the first hour of life in the Legal Amazon, suggesting the need of differentiated strategies for the promotion of exclusive breastfeeding.

    The sandfly fauna is well studied globally. In Brazil, sandfly fauna is very diverse in the Northeast region, especially in states such as Maranhão, Ceará, and Bahia. However, in the State of Pernambuco, the distribution of these insects is still not well known. Therefore, the objective of this study was to identify the different species that constitute the sandfly fauna in an urban area in the Northeast region of Brazil, where an outbreak of visceral leishmaniasis (VL) was recently reported. The sandflies were collected from an urban area endemic for VL, at five collection points. The collection of samples was carried out from November 2014 to December 2015, using CDC light traps installed in intradomiciliary and peridomiciliary fashion. The collected sandflies (n = 297) belonged to eight species: Lutzomyia lenti, Lutzomyia longipalpis, Lutzomyia sallesi, Lutzomyia migonei, Lutzomyia walkeri, Lutzomyia capixaba, Lutzomyia carmelinoi, and Lutzomyia whitmani. Most of the specimens collected were peridomiciliary (247/297, 83%). L. lenti (154/297, 52%) was the most frequently sampled species, followed by L. longipalpis (88/297, 29.6%), and L. sallesi (42/297, 14.1%), which together accounted for over 90% of the collected sandfly specimens. The continued presence of L. longipalpis in urban areas, including that in intradomiciliary areas, with a predominance of females, is crucial because of the high possibility of them causing VL outbreaks, since this species is the main vector of Leishmania infantum in Brazil.

    The monthly patterns of northeast Brazil (NEB) precipitation are analyzed in relation to sea surface temperature (SST) in the tropical Pacific and Atlantic Oceans, using singular value decomposition. It is found that the relationships between precipitation and SST in both basins vary considerably throughout the rainy season (February-May). In January, equatorial Pacific SST is weakly correlated with precipitation in small areas of southern NEB, but Atlantic SST shows no significant correlation with regional precipitation. In February, Pacific SST is not well related to precipitation, but south equatorial Atlantic SST is positively correlated with precipitation over the northern Nordeste, the latter most likely reflecting an anomalously early (or late) southward migration of the ITCZ precipitation zone. During March, equatorial Pacific SST is negatively correlated with Nordeste precipitation, but no consistent relationship between precipitation and Atlantic SST is found. Atlantic SST-precipitation correlations for April and May are the strongest found among all months or either ocean. Precipitation in the Nordeste is positively correlated with SST in the south tropical Atlantic and negatively correlated with SST in the north tropical Atlantic. These relationships are strong enough to determine the structure of the seasonal mean SST-precipitation correlations, even though the corresponding patterns for the earlier months of the season are quite different. Pacific SST-precipitation correlations for April and May are similar to those for March. Extreme wet (dry) years for the Nordeste occur when both Pacific and Atlantic SST patterns for April and May occur simultaneously. A separate analysis reinforces previous findings in showing that SST in the tropical Pacific and the northern tropical Atlantic are positively correlated and that tropical Pacific-south Atlantic correlations are negligible.Time-lagged analyses show the potential for forecasting either seasonal mean

    This study shows the pioneer results of the water quality characterization of a lake region, including the Piratuba lake (within the limits of the Piratuba Lake Biological Reservation) and the Sucuriju river, localized at the northeast portion of the Amapa State, Brazil, and left margin of the Amazon River mouth. Due to the influence of the Amazon river and another important river, the Araguari river, the northeast coast of Amapa State receive little impact of salty water from the Atlantic ocean. The highest salinity values detected on this coastal area is 20 psu. The Piratuba Lake region which can be described as an unique wetland system formed by recent geological processes (Quaternary), it constitutes a very fragile environment and possesses a number of shallow water lakes distributed into a mixed mangrove and "varzea" type of vegetation and it is considered very important looking at the biological point of view. The borderline between this lake system with the coastal waters is a narrow portion of mangrove containing species of Rizhophora and Avicennia parallel to the coast line. A preliminary water circulation could be accessed through the detection of variation in water quality parameters throughout three field studies conducted on March, 2004, June 2005 and November 2005. Surface water sampling points spatially distributed on the study area with distances less than 2 km were set, covering almost 800 square kilometers. Among the parameters studied (pH, electrical conductivity, turbidity, concentration of suspended solids, depth, temperature, chloride, dissolved oxygen, nitrate, nitrite and phosphate) the turbidity, electrical conductivity and pH were the most important for identifying the entering of coastal waters into the lake region. Mainly, three points of direct contact were identified; one of them is a manmade illegal entrance to the Biological Reservation. The seasonal variation was also very important factor and as expected, during the dry season

    Full Text Available Coccidioidomycosis is an endemic infection with a relatively limited geographic distribution: Mexico, Guatemala, Honduras, Colombia, Venezuela, Bolivia, Paraguai, Argentina and the southwest of the United States. In these countries, the endemic area is restricted to the semiarid desert like regions which are similar to the northeast of Brazil. Case report: The patient is a 32 year-old male, born in the state of Bahia (Northeast of Brazil and has been living in São Paulo (Southeast for 6 years. He was admitted at Hospital das Clínicas, at the Department of Pneumology in October 1996, with a 6 month history of progressive and productive cough, fever, malaise, chills, loss of weight, weakness and arthralgia in the small joints. Chest x-rays and computerized tomography disclosed an interstitial reticulonodular infiltrate with a cavity in the right upper lobe. The standard potassium hydroxide preparation of sputum and broncoalveolar lavage demonstrated the characteristic thickened wall spherules in various stages of development. Sabouraud dextrose agar, at 25° C and 30° C showed growth of white and cottony aerial micelium. The microscopic morphology disclosed branched hyphae characterized by thick walled, barrel shaped arthroconidia alternated with empty cells.

    Clóvis Eduardo Santos Galvão

    Full Text Available CONTEXT: Some studies have shown that inflammatory processes in the nasal air passages may reflect or affect those in the lower airways. We decided to indirectly assess the inflammatory status of the nasal airways in two groups of children with different sensitization rates to aeroallergens. OBJECTIVE: To compare the inflammatory activity in the nasal airways, through the determination of mediators in nasal lavage fluid in two distinct populations. TYPE OF STUDY: Cross-sectional study. SETTING: Two public elementary schools, one in an urban setting and the other in a rural setting of the State of São Paulo, Brazil. METHODS: Two groups of 40 elementary school children with different sensitization rates to aeroallergens were formed. Samples of nasal lavage fluid were assessed for eosinophil cationic protein (ECP and tryptase. Non-parametric tests were used for statistical analysis. RESULTS: Significantly higher levels of ECP were observed among students living in the urban area than those in the rural area (p < 0.05. No significant difference in the tryptase levels was observed. Also, the urban children who were sensitized to aeroallergens presented higher levels of ECP in nasal mucosa than the non-sensitized children, while this difference was not observed among the rural children. DISCUSSION: The lack of mast cell activity and increased eosinophil degranulation revealed a chronic inflammatory state in the nasal air passages. The higher eosinophil activity in the urban area, coinciding with higher sensitization to aeroallergens, suggests that there must be some factors in the urban area that can modulate airway inflammation by influencing the activation of inflammatory cells. CONCLUSION: Our findings showed that there was no difference in the concentrations of tryptase in nasal lavage fluids between the two studied groups. However, the children from the urban area presented with higher concentrations of eosinophil cationic protein than did those

    In Northeast Brazil, large domestic containers used to store water are important breeding sites of Aedes aegypti, the main vector of dengue fever. The objective of this study was to estimate the survival of Betta splendens (Perciformes: Osphronemidae) fish in domestic containers in Fortaleza (Ceará State), as well as its effectiveness in the control of premature A. aegypti stages. The use of B. splendens was compared to Bacillus thuringiensis israelensis (Bti) in domestic containers. In a first home visit, B. splendens or Bti were applied to water containers. Two follow-up visits were conducted after 3-4 and 5-6 months to assess the presence of viable fish in the containers and infestation by larvae. Betta splendens fish were still present in 97.6% of containers 45-60 days after application. When the fish was present, the infestation rate was significantly higher (P containers, but that appropriate measures should be taken to assure prolonged survival and the presence of fish in the containers. © 2010 Blackwell Publishing Ltd.

    Scapolites are relatively common constituents of calcium-rich metamorphic rocks. They can be considered as members of the solid solution series marialite and meionite. Relationship between the optical properties, chemical composition and X-ray diffraction data shows that scapolites from northern Brazil are mizzonites and meionites. The structures of these minerals are compatible only with a primitive lattice. The d hkl peaks of natural scapolites are outside the range shown by the two pure end-members of the series, and the unit-cell dimensions increase with percentage of (K+SO 4 ). X-ray diffraction powder data for natural tetragonal and orthorhombic calcium-rich scapolites are detailed in five tables. (author) [pt

    Full Text Available Similar to other parts of the world, the prevalence of type 2 diabetes mellitus (T2DM in the Asia-Pacific Region has rapidly increased during the last few decades. The purposes of this pilot study were to determine the feasibility and the effects of a capacity building program for Village Health Volunteers (VHVs to support self-management in a T2DM high risk population from a rural subdistrict in Northeast Thailand. Both quantitative and qualitative data were collected using surveys, focus group discussions, and in-depth interviews. Data were analyzed and used to develop a 12-week capacity building program for VHVs. This program was then implemented on 60 subjects at high risk of T2DM in the selected community. According to the paired t-test and Wilcoxon-signed rank test, VHVs had higher scores on knowledge and self-efficacy of T2DM prevention after a 12 week intervention (p = .03 and p = .02, respectively. Study participants at risk for T2DM also had a significant increase in T2DM knowledge and self-management (p < .001. Implementation of the capacity building program for VHVs in Northeast Thailand was feasible. The key successes were strong community bonding, community empowerment, and support from family and public health nurses. Effects of the program should be examined with those in other Asia-Pacific countries.

    Full Text Available Technological advance has been the main driving force behind the developing regions, accounting for much of the increase in productivity, income, job creation and international competitiveness. In that sense, the Habitat's innovation, but specifically, the technological parks, undertakings promoters of the culture innovation, competitiveness, increase and business qualification, substantiated in the transference of knowledge and technology, with the objective of increase the output of wealth of a region. Thus, the objective this paper is to identify the potential to economic development and innovative place technology parks that are in operation in northeast Brazil. The results are derived from a qualitative research study, based on descriptive and exploratory research, which through a five case studies it was possible to obtain information about the topic. The finding indicates that the technology parks presents potentials that identify them, as inductors of the economic development and local inovativon. Also, it presents limits that in spite of it they do not lessen the potential the localities of excellence for the transfer of technology based in technological base companies. It presents itself as difficulties that should be minimized or depending on the situation, solved through actions of the actors involved in behalf of the economic development and local inovativon.

  3. Environmental benefits of electricity grid interconnections in Northeast Asia

    From an environmental perspective, electricity grid interconnections in Northeast Asia make sense. Cities in Northeast China, Mongolia, the Democratic People's Republic of Korea (DPRK), and the Republic of Korea (ROK) suffer from poor air quality due to the extensive use of coal-fired power generation. Rural communities suffer from a deficit of electricity, forcing reliance on coal and biofuels for cooking and heating in the home, which causes health-damaging indoor air pollution. Regional air pollution from acid rain and ozone is widespread. In addition, Japan is finding it hard to meet its commitment under the Kyoto Protocol. Yet, just across their borders in far eastern Russia are extensive, clean energy resources: hydroelectricity and natural gas, and (potentially) nuclear power and tidal power. It would be environmentally beneficial to generate electricity cleanly in far eastern Russia and transmit the electricity across the borders into China, Mongolia, the DPRK, the ROK, and Japan, thereby displacing coal-fired electricity generation. We estimate that currently planned projects could alleviate the problems of two to five Chinese cities, with the potential for much larger benefits in the future. (author)

    Diabetic retinopathy has a significant impact in every healthcare system. Despite that fact, there are few accurate estimates in the prevalence of DR in Brazil's different geographic regions, particularly proliferative DR and diabetic macular edema. This study aims to determine the prevalence of diabetic retinopathy in Brazil's five continental regions and its determinant factors. This multi center, cross-sectional, observational study, conducted between August 2011 and December 2014, included patients with type 1 diabetes from the 5 Brazilian geographic regions (South, Southeast, North, Northeast and Midwest). During a clinical visit, a structured questionnaire was applied, blood sampling was collected and each patient underwent mydriatic binocular indirect ophthalmoscopy evaluation. Data was obtained from 1644 patients, aged 30.2 ± 12 years (56.1% female, 54.4% Caucasian), with a diabetes duration of 15.5 ± 9.3 years. The prevalence of diabetic retinopathy was 242 (36.1%) in the Southeast, 102 (42.9%) in the South, 183 (29.9%) in the North and Northeast and 54 (41.7%) in the Midwest. Multinomial regression showed no difference in the prevalence of non-proliferative diabetic retinopathy in each geographic region, although, prevalence of proliferative diabetic retinopathy (p = 0.022), and diabetic macular edema (p = 0.003) was higher in the Midwest. Stepwise analyses reviled duration of diabetes, level of HbA1c and hypertension as independent variables. The prevalence of non proliferative diabetic retinopathy in patients with type 1 diabetes was no different between each geographic region of Brazil. The Midwest presented higher prevalence of proliferative diabetic retinopathy and diabetic macular edema. Duration of DM and glycemic control is of central importance to all. Hypertension is another fundamental factor to every region, at special in the South and Southeast. Glycemic control and patients in social and economic vulnerability deserves

    There is some evidence that dogs can be naturally infected by Paracoccidioides brasiliensis in endemic areas of paracoccidioidomycosis. In order to evaluate canine infection with this fungus, a survey with 149 urban and 126 rural dogs was carried out using ELISA and intradermal tests with the gp43 antigen of P. brasiliensis in Uberaba, Minas Gerais state of Brazil. Forty-one out of 149 urban dogs were euthanatized and had their lungs, liver and spleen removed. One slice from each viscera was processed for histopathological examination and the remaining was homogenized and then cultivated on mycobiotic agar at room temperature and Fava-Netto medium at 35 degrees C and observed for 12 weeks. Of urban dogs, 75 (50.3%) were small adult females, 56 (36%) were strays, while 93 (64%) had been donated to the municipal zoonosis control center. Nine (6.2%) had a positive intradermal test without statistical differences regarding gender, race, nutritional status or origin. No colonies with microscopic or morphology appearances resembling P. brasiliensis were isolated, nor granulomatous process or fungal structures were observed from histopathological examination. Eighty (53.6%) of the urban dogs presented seroreactivity, without statistical differences regarding gender, race, nutritional state, origin, or positive intradermal test. Of 126 rural dogs, 102 (80.5%) presented antibodies against gp43 antigen, and this was statistically significant in relation to the reactivity detected in urban dogs (P = 0.0001). Thus, dogs are commonly infected with P. brasiliensis, but they probably present natural resistance to develop paracoccidioidomycosis.

    Full Text Available ABSTRACT: This study aimed to analyze loads resulting from the rural work of fruit and vegetable farmers. This exploratory and descriptive study was conducted with 259 farm workers from two rural environments. A semi-structured questionnaire based on the concepts of NASA-TLX was used to assess workload. The male and female workers of one environment reported that the demand that contributed the most to their workload was the level of total effort, while the women of the other environment reported that the physical demand was more relevant for WL. In conclusion, evidence concerning workload supports further investigation into the health of rural workers and the development of preventive strategies related to rural work.

    Sediment contamination by metals poses risks to coastal ecosystems and is considered to be problematic to dredging operations. In Brazil, there are differences in sedimentology along the Large Marine Ecosystems in relation to the metal distributions. We aimed to assess the extent of Al, Fe, Hg, Cd, Cr, Cu, Ni, Pb and Zn contamination in sediments from port zones in northeast (Mucuripe and Pecém) and southeast (Santos) Brazil through geochemical analyses and sediment quality ratings. The metal concentrations found in these port zones were higher than those observed in the continental shelf or the background values in both regions. In the northeast, metals were associated with carbonate, while in Santos, they were associated with mud. Geochemical analyses showed enrichments in Hg, Cd, Cu, Ni and Zn, and a simple application of international sediment quality guidelines failed to predict their impacts, whereas the use of site-specific values that were derived by geochemical and ecotoxicological approaches seemed to be more appropriate in the management of the dredged sediments.

To identify the prevalence of metabolic syndrome (MS, and the influence of gender and place of residence for elders served by the Family Health Strategy in the municipality of Coimbra (Minas Gerais state, Brazil. Methodology. The sample consisted of 435 individuals of both sexes, with mean of age 72 ± 8 years. Results. Women had higher prevalence rates of MS (urban= 40%, rural= 37% with differences (p<0.05, = 0.168 and 0.284 for men (urban= 13%, rural= 22%. Odds Ratio for SM was significant in age groups over 65 years in urban areas, with women having higher chances compared with men (OR=3.07 times, becoming 5.8 times aged 75 to 79 years. Women are more exposed to obesity (urban= 80.4 %, rural= 78.6% than men, regardless of place of residence (p<0.05, =0.46 and 0.47 respectively, and the urban women are still exposed to hypertension (65%, p= 0.022, = 0.12. Conclusion. The prevalence of MS and exposure to risk factors such as obesity and hypertension was higher in women, mainly in urban areas. Health professionals, like nurses, should note that the elderly population in urban areas have greater exposure to risk factors for MS, which should strengthen educational programs that promote healthy lifestyles.

    2008-04-01

    Full Text Available This anthropological study critically evaluates Brazilian caregivers' symbolic production and significance of their malnourished offspring's primary teeth, as well as their own, and describes popular dental practices. From January to June 2004, ethnographic interviews of 27 poor, low-literacy mothers were conducted at a public Malnutrition Treatment Center in Fortaleza, Ceará State. Participant observation of clinical pathways and home environments supplemented the data. Content analysis was performed. Results confirm that primary teeth are imbued with cultural significance in Northeast Brazil. Mothers examine mouths, perceive signs of decay, associate primary with permanent tooth healthiness, identify ethnodental illnesses, seek assistance, and perform rituals with exfoliated teeth. The mother's motivation to care for primary teeth is sparked by her memories of past toothache and attempts to avoid stigma and discrimination. Social determinants, not mothers' beliefs or behaviors, are the most critical obstacles to effective dental care. Legitimizing lay knowledge and empowering caregivers and children can improve oral health in Northeast Brazil.Este estudo antropológico analisa a produção simbólica de cuidadoras brasileiras sobre a sua dentição e a de seus filhos desnutridos, descrevendo práticas populares de cuidados em saúde bucal. De janeiro a junho de 2004, foram conduzidas entrevistas etnográficas com 27 cuidadoras, numa instituição pública, no tratamento de desnutrição em Fortaleza, Ceará. A observação participante da dinâmica de atendimento e do ambiente domiciliar suplementaram os dados. Foi utilizada a análise temática. Os resultados confirmam que os dentes decíduos são imbuídos de significados culturais no nordeste brasileiro. As mães examinam as bocas dos filhos, percebem sinais de cárie, associam dentes decíduos saudáveis com permanentes hígidos, identificam enfermidades etnodentárias, procuram assist

    Full Text Available The size at sexual maturity and the allometric growth of the semi-terrestrial crab Sesarma rectum were studied in an impacted tropical mangrove in northeast Brazil. Crabs were monthly collected during spring low-tide periods, from October 2009 through September 2010. A catch-per-unit-effort (CPUE technique was used to sample the crab population, with two-hour sampling periods, by two people. A total of 492 crabs were obtained, being 262 males and 230 females. The specimens were measured at carapace width (CW, the left and right propodus length and height (RPL, RPH, LPL and LPH, and the gonopod length of males (GL, and abdomen width (AW of females. In males, the inflection point was at 27.14 mm CW in the relationship between CW and the length of right propodus (LRP, considering the morphological size at the onset of maturity. Based on the relationship between CW and AW, the size at sexual maturity in females was 22.97 mm. In spite of living in an impacted area, this population attained the maturity onset at a bigger size than other localities.

    A Mucoralean fungus was isolated from Caatinga soil of Pernambuco, Northeast of Brazil, and was identified as Cunninghamella echinulata by morphological, physiological, and biochemical tests. This strain was evaluated for biosurfactant/bioemulsifier production using soybean oil waste (SOW) and corn steep liquor (CSL) as substrates, added to basic saline solution, by measuring surface tension and emulsifier index and activity. The best results showed the surface water tension was reduced from 72 to 36 mN/m, and an emulsification index (E₂₄) of 80% was obtained using engine oil and burnt engine oil, respectively. A new molecule of biosurfactant showed an anionic charge and a polymeric chemical composition consisting of lipids (40.0% w/w), carbohydrates (35.2% w/w) and protein (20.3% w/w). In addition, the biosurfactant solution (1%) demonstrated its ability for an oil displacement area (ODA) of 37.36 cm², which is quite similar to that for Triton X-100 (38.46 cm²). The stability of the reduction in the surface water tension as well as of the emulsifier index proved to be stable over a wide range of temperatures, in pH, and in salt concentration (4%-6% w/v). The biosurfactant showed an ability to reduce and increase the viscosity of hydrophobic substrates and their molecules, suggesting that it is a suitable candidate for mediated enhanced oil recovery. At the same time, these studies indicate that renewable, relatively inexpensive and easily available resources can be used for important biotechnological processes.

    Full Text Available Childhood diarrheal diseases remain highly endemic in northeastern Brazil. The attributable fraction of all diarrheal diseases among children less than 2 years of age due to Escherichia coli was examined in a 2-year prospective study in two large urban centers of Brazil. Between May 1997 and June 1999, fecal E. coli isolates from 237 children with diarrhea (217 acute and 20 persistent cases and 231 children without diarrhea (controls attending two hospitals in Northeast Brazil were tested for their pattern of adherence to HEp-2 cells and for colony hybridization with DNA probes specific for the six pathotypes of diarrheagenic E. coli. Enteroinvasive E. coli, enterotoxigenic E. coli and enterohemorrhagic E. coli were not isolated from any children. Diffusely adherent E. coli (DAEC and enteroaggregative E. coli (EAEC were the most frequent isolates with similar frequencies from children with or without diarrhea. Atypical EPEC (EAF-negative strains were isolated with similiar frequency from both cases (5.5% and controls (5.6%. Enteropathogenic E. coli (typical EPEC strains, characterized by localized adherence pattern of adherence, hybridization with the EAF probe, and belonging to the classical O serogroups, were significantly associated with diarrhea (P = 0.03. These E. coli strains associated with diarrhea accounted for 9% of all children with diarrhea. Collectively, in Northeast Brazil, E. coli strains comprise a small proportion of severe diarrhea prevalence in children.

    2013-06-01

    Full Text Available Although with few records among studies in political ethnology of indigenous groups in Northeast Brazil, the awakening of the ethnonym anacé, on the west coast of Ceará State, has been especially important to considerations on the new frontiers of development programs and the current mobilization of regimens of memory and political agency around the certification of territorial rights for indigenous peoples in the region. The article analyzes the re-elaboration of the anacé ethnicity from two events that mix a narrative of the indigenous emergence with the national drama that stated Northeast Brazil as a problematic region in what regards development. How is the indigenous presence in a scenario of large-scale projects implementation combined with a region characterized as economically problematic? And how this compound affects the current anacé political mobilization? In order to analyze these issues, this paper proposes reflections shared by authors in political ethnology, development anthropology and anthropology of globalization.

    Full Text Available Introduction The yellow fever epidemic that occurred in 1972/73 in Central Brazil surprised the majority of the population unprotected. A clinical-epidemiological survey conducted at that time in the rural area of 19 municipalities found that the highest (13.8% number of disease cases were present in the municipality of Luziânia, State of Goiás. Methods Thirty-eight years later, a new seroepidemiological survey was conducted with the aim of assessing the degree of immune protection of the rural population of Luziânia, following the continuous attempts of public health services to obtain vaccination coverage in the region. A total of 383 volunteers, aged between 5 and 89 years and with predominant rural labor activities (75.5%, were interviewed. The presence of antibodies against the yellow fever was also investigated in these individuals, by using plaque reduction neutralization test, and correlated to information regarding residency, occupation, epidemiological data and immunity against the yellow fever virus. Results We found a high (97.6% frequency of protective titers (>1:10 of neutralizing antibodies against the yellow fever virus; the frequency of titers of 1:640 or higher was 23.2%, indicating wide immune protection against the disease in the study population. The presence of protective immunity was correlated to increasing age. Conclusions This study reinforces the importance of surveys to address the immune state of a population at risk for yellow fever infection and to the surveillance of actions to control the disease in endemic areas.

    This study analyses health managers' perceptions of local public health agendas addressing violence against rural women in municipalities in the southern part of the State Rio Grande do Sul in Brazil. It consists of an exploratory descriptive study utilizing a qualitative approach. Municipal health managers responsible for planning actions directed at women's health and primary health care were interviewed. The analysis sought to explore elements of programmatic vulnerability related to violence in the interviewees' narratives based on the following dimensions of programmatic vulnerability: expression of commitment, transformation of commitment into action, and planning and coordination. It was found that local health agendas directed at violence against rural women do not exist. Health managers are therefore faced with the challenge of defining lines of action in accordance with the guidelines and principles of the SUS. The repercussions of this situation are expressed in fragile comprehensive services for these women and programmatic vulnerability.

    Surprise Valley Electric, a small rural electric cooperative serving northeast California and southern Oregon, developed a 3mw binary geothermal electric generating plant on a cooperative member's ranch. The geothermal resource had been discovered in 1980 when the ranch was developing supplemental irrigation water wells. The 240°F resource was used for irrigation until developed through this project for generation of electricity. A portion of the spent geothermal fluid is now used for irrigation in season and is available for other purposes, such as greenhouse agriculture, aquaculture and direct heating of community buildings. Surprise Valley Electric describes many of the challenges a small rural electric cooperative encountered and managed to develop a geothermal generating plant.

    Full Text Available In Brazil, species of the genus Liriomyza are widely distributed and have economic importance as they cause damage to at least 14 plant families, especially Solanaceae, Cucurbitaceae, Asteraceae, and Fabaceae. Studies suggest existence of a species complex within this genus, based on the presence of morphological similarities among the species Liriomyza trifolii (Burgess, L. sativae Blanchard and L. huidobrensis (Blanchard. The present study aimed to use DNA barcoding to establish new distribution records of L. sativae in distinct regions in Brazil, determine intra- and inter-population genetic diversity, and reconstruct the phylogeny of Liriomyza species using the DNA barcode sequences. Identity values were between 97% and 99%, confirming that all the examined Brazilian populations belonged to the species L. sativae. Phylogenetic analyses indicated the presence of a single clade of L. sativae, composed of seven populations. Intra-population analysis on individuals of these populations indicated low levels of nucleotide and haplotype diversity. The haplotype network indicated presence of only 14 haplotypes distributed among the Brazilian populations. The genetic similarities shared by the Brazilian populations of L. sativae suggest that these populations are closely related. Genetic patterns observed among populations of L. sativae might be associated with bottleneck events or founder effect during establishment of this leafminer in Brazil.

    Full Text Available Sedimentological and radiocarbon investigations are part of an ongoing research on the Bay-head delta of northeast Guanabara Bay, Rio de Janeiro State. Sediment accumulation indicates that the Holocene infill of the bay-head delta started around 8.2 kyr BP and was not in pace with the eustatic sea-level rise. Sediment accumulation was faster during the transgressive phase (0.56 cm.yr-1. However, during the regressive phase, progradation driven by base-level fall was predominant over vertical sediment accumulation (0.02 cm.yr-1. Based on coring, three sedimentary units were defined: fluvial sands (U1, estuarine deposits (U2 and fluvial mud (U3.

This study investigated the magnitude, temporal trends and spatial distribution of mortality related to VL in Brazil. Methods We performed a study based on secondary data obtained from the Brazilian Mortality Information System. We included all deaths in Brazil from 2000 to 2011, in which VL was recorded as cause of death. We present epidemiological characteristics, trend analysis of mortality and case fatality rates by joinpoint regression models, and spatial analysis using municipalities as geographical units of analysis. Results In the study period, 12,491,280 deaths were recorded in Brazil. VL was mentioned in 3,322 (0.03%) deaths. Average annual age-adjusted mortality rate was 0.15 deaths per 100,000 inhabitants and case fatality rate 8.1%. Highest mortality rates were observed in males (0.19 deaths/100,000 inhabitants), Brazil over the period, with different patterns between regions: increasing mortality rates in the North (Annual Percent Change – APC: 9.4%; 95% confidence interval – CI: 5.3 to 13.6), and Southeast (APC: 8.1%; 95% CI: 2.6 to 13.9); and increasing case fatality rates in the Northeast (APC: 4.0%; 95% CI: 0.8 to 7.4). Spatial analysis identified a major cluster of high mortality encompassing a wide geographic range in North and Northeast Brazil. Conclusions Despite ongoing control strategies, mortality related to VL in Brazil is increasing. Mortality and case fatality vary considerably between regions, and surveillance and control measures should be prioritized in high-risk clusters. Early diagnosis and treatment are fundamental strategies for reducing case fatality of VL in Brazil. PMID:24699517

    Gestation is a period that can positively or negatively influence the life of a woman in the pregnancy-puerperal cycle. Thus, evaluating the quality of life of this population can redirect the implementation of innovative practices, with the goal of making them more effective and practical or the promotion of humanized care. The present study aimed to evaluate the predictors that influence the health-related quality of life of low-risk pregnant women, as well as to describe the main areas affected in the quality of life of pregnant women. A correlational, quantitative and cross-sectional study was carried out in two public units that provide prenatal care services and a private unit in the city of Fortaleza, a municipality in the Northeast of Brazil. The sample consisted of 261 pregnant women who were interviewed from September to November 2014. The collection instruments were a questionnaire covering sociodemographic, obstetric and quality of life variables, in addition to the Brazilian version of the Mother-Generated Index (MGI). The data were compiled and analyzed through the Statistical Package for the Social Sciences (SPSS) software, version 20.0. A descriptive analysis was performed through the application of Pearson's chi-square test, Fisher's exact test and one-way ANOVA. Maternal predictors for the quality of life of pregnant woman were identified through a multivariate analysis/multiple regression. The response rate was 100%, corresponding to 261 respondents. Occupation, parity, partner support, marital status and persons with whom the women live were the predictors that positively interfered in the quality of life of pregnant women. In contrast, gestational age, type of housing, occupation, use of illicit drugs, non-receipt of partner support and maternal age were the predictors that negatively influenced quality of life. Our results indicate that happiness to become a mother and body image were areas with the greatest positive and negative influence on

    Hepatozoon canis is a tick-borne parasite that occurs worldwide. In rural areas of Brazil, H. canis vectors remain unknown, which has led to speculation about alternative routes of transmission. Small rodents can play a role in the transmission (via predation) of Hepatozoon americanum, which led us to question whether predation might be an alternative mode of transmission for H. canis. Thus, this study investigated whether Hepatozoon spp. are present in wild small rodents in forest fragments that surround rural areas in Botucatu County, São Paulo, Brazil, where canine hepatozoonosis is endemic. The study included blood samples from 158 dogs, which were screened by microscopy and molecular analysis. Blood samples and tissues from 67 rodents were obtained for histopathology and molecular detection. The prevalence of H. canis was high (66.45%) in dogs from rural areas of Botucatu, São Paulo, Brazil. The molecular analysis showed that wild rodent species in Brazil were infected with Hepatozoon spp. other than H. canis. Therefore, although the hypothesis that sylvatic rodents act as reservoirs for H. canis was not supported, the presence of monozoic cysts in the rodents suggests that, in addition to intermediate hosts, wild small rodents in Brazil might act as paratenic hosts of Hepatozoon spp. because they harbor infective stages for intermediate host predators.

    The availability of energy resources is a central point to economic development. The energy matrix of most countries is based on the consumption of fossil fuels, which adds annually over 5 billion tons of carbon into the atmosphere. The energy consumption in developing countries has quadrupled since the 60s further aggravating global environmental conditions. The need to implement alternative energy sources to the energy matrix was proved. In addition, Brazil has a large number of people without access to electricity, which affects the quality of life of these populations. In this context, it is necessary to think in economic development way, and then the sustainable and alternative sources appear as an option for its features and its availability in Brazil. The solar energy captured by photovoltaic cells can be highlighted in the Brazilian scenario because of its wide availability, especially in the Northeast. The aim of this paper is to estimate the economic feasibility of insertion of solar systems in small communities in the Brazilian Northeast, considering environmental costs involved in electricity generation. The methodology is based on economic concepts and economic valuation of environmental resources. The results shows that solar power is becoming increasingly competitive due to reduced costs of components and due to the environmental costs reduced when compared with fossil fuels. (author)

    A field study near the copper smelter of a large industrial complex examined air pollution effects on vegetation and soil parameters in Camacari (northeast Brazil). Close to the smelter, soil pH-value was lower and total acidity as well as organic carbon contents were higher compared with a site far from the source and two reference sites. The acidification of top soil particularly and the drastically enhanced plant-available copper concentrations were caused by atmospheric deposition. High sulphur and copper deposition significantly reduced microbial biomass and altered functional diversity of soil microorganisms (arylsulphatase and xylanase). Large accumulations of sulphur, arsenic and copper were detected in mango leaves (Mangifera indica) growing downwind from the smelter suggesting potential food chain-mediated risk. - Atmospheric emissions in northeast Brazil have transformed soil pH, accumulated in soil and plants as sulphur and heavy metals, and affected the functional diversity of soil microorganisms

    Full Text Available Objective: To describe co-infections, clinical manifestations, comorbidities and outcome of patients with visceral leishmaniasis and AKI. Methods: This is a case study with ten patients with confirmed diagnosis of VL admitted to the reference ICU of Northeast of Brazil during 6 years, with renal injury. Clinical and laboratory parameters were evaluated in admission, period of hospitalization and outcome. Results: This study found 10 patients with VL in a group of 253 patients admitted to the ICU with AKI. The main signs and symptoms presented at admission were weight loss, fever, splenomegaly, jaundice, anorexia, asthenia, bleeding and vomits. The main co-infections were: AIDS, tuberculosis and leprosy. Patients were classified in RIFLE criteria. RIFLE-F patients were younger and had a longer time between onset of symptoms and hospital admission. Death was observed in 60% of cases. The causes of death were septic shock, respiratory insufficiency and multiple organ dysfunction. Conclusions: AKI is an important complication in VL. The progression of the disease and their complications can achieve high level of severity, even in the absence of comorbidities or co-infections. The high mortality in this group alerts to the importance of adequate management of these patients.

    Full Text Available In goat and sheep flocks, mycoplasmosis is a disease that may cause severe economical losses associated with polyarthritis, mastitis, agalactia, conjunctivitis, pneumonia and reproductive failure. The latter may involve repeat breeding, granular vulvovaginitis, infertility and abortions. The aim of the present study was to assess the occurrence of Mycoplasma agalactiae (Ma in semen and milk samples from naturally infected goat in the semiarid region from Pernambuco State, Northeast from Brazil. Thirty-nine semen samples and 81 milk samples were submitted to DNA extraction using a commercially available kit and following the manufacturer's instructions. The polymerase chain reaction (PCR was then performed in accordance with protocols described in the literature. The results of the present study revealed the presence of Ma in the DNA of 17.9% (7/39 of the semen samples and 3.7% (3/81 of the milk samples. The results obtained in the present study confirm the elimination of the DNA of Ma in the semen and milk samples. The presence of this agent in goat flocks is considered very risky in terms of reproductive disorders and contagious agalactia outbreaks in the Northeast region of Brazil.

    Full Text Available Romania's population has declined steadily from 23.2 million in 1990 to 21.5 million inhabitants in 2007. This overall decline in population is not entirely true for the towns and cities of the North-East Region, as during the same period they recorded both decreases and increases in population due to positive natural balance. The North-East Region (partially superimposed over the historic region of the western Moldova is considered the poorest region in the European Union and a disadvantaged area. The rural young population of Moldova is a reservoir which supplies urban areas and especially large cities. In these circumstances, the small towns of the North-East Region are seeking balance (demographic, economic, functional. This paper examines the demographic evolution of the small towns located in the area under analysis, in the post-communist period, illustrating the types of fluctuations in statistical methods as regards demographic changes and the risk of depopulation in the future, correlated with a lower overall population of Romania.

  13. Rural Poverty and Diversification of Farming Systems in Upper Northeast Thailand

    2013-04-01

    Full Text Available In northeast Thailand, 85% of the farmers are smallholders who are unable to meet their basic needs from agricultural production only. These tiny farms survive thanks to non-farm income, which faces increased difficulties as other economic sectors ran out of steam during the recent economic crisis of the late 1990s. In this context, farmers have to rely more on their agricultural production activity and income. But how can this be made possible in a region well-known for its very constraining soil and climatic conditions? To answer this question, and to examine the whole complexity of agricultural development issues, this article proposes an analysis of recent agrarian transformations and an understanding of farmers’ current practices and strategies. A diagnostic analysis of a village agrarian system located in Khon Kaen Province in upper northeast Thailand was carried out in 2002 by using a combination of field observations, interviews with key witnesses of the local history, and a farm survey of 26 diverse households. The recent history illustrates that farmers have shown a high adaptability to rapid changes in their economic environment, such as changing market demand for agricultural products and labour. The differentiation among farming households has led to different types of farmers with different resources, practices, and strategies. Families belonging to the most frequent type have a very tiny holding and their members are permanently or seasonally involved in unskilled off-farm activities. Their low and unstable total cash income is often insufficient to meet the family’s basic needs and they become deeply indebted. As efforts to improve water availability are being made, many Isarn families could improve their living conditions by diversifying their agricultural production systems with more small-scale fruit, vegetable, fish, or livestock production to improve household food security and cash income, eventually combined with non

    Full Text Available Fish consumption per capita in Brazil is relatively modest when compared to other animal proteins. This study analyses the influence of protein prices, other food prices and population income on the fish demand in Brazil. First, the problem of fish supply in Brazil is characterized. It is followed by reviews of the relevant economic theory and methods of Almost Ideal Demand System - AIDS and their elasticity calculations. A descriptive analysis of fish demand in Brazil using the microdata called "Pesquisa de Orçamento Familiar" (Familiar Budget Research - POF 2002-2003 is presented. Finally, demand functions and their elasticities are calculated for two different cases: one considering five groups of animal proteins (Chicken; Milk and Eggs; Fish; Processed Proteins and Red Meat and other with seven groups of food categories (Cereals; Vegetables and Fruits; Milky and Eggs; Oils and Condiments; Fish; Other processed foods; and Meats. The main results are: per capita consumption of fish (4.6 kg per inhabitant per year is low in Brazil because few households consume fish. When only households with fish consumption are considered, the per capita consumption would be higher: 27.2 kg per inhabitant per year. The fish consumption in the North-East Region is concentrated in the low-income class. In the Center-South Region, the fish consumption is lower and concentrated in the intermediate income classes. The main substitutes for fish are the processed proteins and not the traditional types of meat, such as chicken and red meat.

    Full Text Available This study analyses health managers' perceptions of local public health agendas addressing violence against rural women in municipalities in the southern part of the State Rio Grande do Sul in Brazil. It consists of an exploratory descriptive study utilizing a qualitative approach. Municipal health managers responsible for planning actions directed at women's health and primary health care were interviewed. The analysis sought to explore elements of programmatic vulnerability related to violence in the interviewees' narratives based on the following dimensions of programmatic vulnerability: expression of commitment, transformation of commitment into action, and planning and coordination. It was found that local health agendas directed at violence against rural women do not exist. Health managers are therefore faced with the challenge of defining lines of action in accordance with the guidelines and principles of the SUS. The repercussions of this situation are expressed in fragile comprehensive services for these women and programmatic vulnerability.

METHODS: A sample of 3,073 untreated and treated (chlorinated water from taps (1,594, reservoir used to store treated water (1,033, spring water (96 and private well (350 collected for routine testing between 1996 and 1999 was analyzed by the multiple dilution tube methods used to detect the most probable number of total and fecal coliforms. These samples were obtained in the region of Maringá, state of Paraná, Brazil. RESULTS: The highest numbers water samples contaminated by TC (83% and FC (48% were found in the untreated water. TC and FC in samples taken from reservoirs used to store treated water was higher than that from taps midway along distribution lines. Among the treated water samples examined, coliform bacteria were found in 171 of the 1,033 sampling reservoirs. CONCLUSIONS: Insufficient treatment or regrowth is suggested by the observation that more than 17% of these treated potable water contained coliform. TC and FC positive samples appear to be similar and seasonally influenced in treated water. Two different periods must be considered for the occurrence of both TC and FC positive samples: (i a warm-weather period (September-March with high percentage of contaminated samples; and (ii cold-weather period (April-August were they are lower. Both TC and TF positive samples declined with the decreased of water temperature.

    Full Text Available ABSTRACT OBJECTIVE This study aims to identify the social and demographic determinants, in addition to the determinants of reproductive health and use of health services, associated with infant mortality in small and medium-sized cities of the North, Northeast and Southeast regions of Brazil. METHODS This is a case-control study with 803 cases of death of children under one year and 1,969 live births (controls, whose mothers lived in the selected cities in 2008. The lists of the names of cases and controls were extracted from the Sistema de Informação sobre Mortalidade (SIM – Mortality Information System and the Sistema de Informação sobre Nascidos Vivos (SINASC – Live Birth Information System and supplemented by data obtained by the research of “active search of death and birth”. Data was collected in the household using a semi-structured questionnaire, and the analysis was carried out using multiple logistic regression. RESULTS The final model indicates that the following items are positively and significantly associated with infant mortality: family working in agriculture, mother having a history of fetal and infant losses, no prenatal or inadequate prenatal, and not being associated to the maternity hospital during the prenatal period. We have observed significant interactions to explain the occurrence of infant mortality between race and socioeconomic score and between high-risk pregnancy and pilgrimage for childbirth. CONCLUSIONS The excessive number of home deliveries and pilgrimage for childbirth indicates flaws in the line of maternity care and a lack of collaboration between the levels of outpatient and hospital care. The study reinforces the need for an integrated management of the health care networks, leveraging the capabilities of cities in meeting the needs of pregnancy, delivery and birth with quality.

    2017-09-01

    Stigma is a powerful determinant of physical and mental health around the world, a perennial public health concern that is particularly resistant to change. This article builds from sociologist Erving Goffman's classic conception of stigma as a unitary social phenomenon to explore the stigma attached to two seemingly dissimilar conditions: food insecurity in rural Brazil, and obesity in the urban United Arab Emirates. Our analyses underscore that both conditions are stigmatized because they represent a departure from a deeply-held social norm, and in both cases, self-stigma plays an important role. Furthermore, in both cases, the stigma associated with food insecurity and obesity is likely at least as harmful to personal wellbeing as are the biological consequences of these conditions. Finally, evidence increasingly links obesity and food insecurity causally. Our analyses suggest that these forms of stigma transcend individuals and are largely structural in their origins, and therefore that they are most likely to be improved through structural change.

    Full Text Available Market-led economic reforms are usually viewed as being in conflict with government-stimulated socioeconomic development for disadvantaged groups. Nevertheless, Ceará, a poor state in the Northeast of Brazil, has since 1987 pursued both of those strategies simultaneously. One part of that approach has been a program of nurse-directed auxiliary health workers serving about 5 million people--almost all the persons outside the capital city and half of those in the capital. The system requires that the auxiliaries, called agentes de saúde, live in the local communities that they serve. The health agents visit each home once a month to carry out a small number of priority health activities. While health agent positions are in high demand, the minimum-wage salary that the agents receive makes up only a small portion of the state budget. A key aspect of the system is timely and comprehensive information, which is based on agent visits and is managed by trained nurses. Since the health agents system was launched, there has been a rapid decline in infant mortality, a rapid rise in immunization, identification of bottlenecks limiting the utilization of other medical resources, and timely interventions in times of crisis. The health agents system has combined administrative decentralization with financial centralization during a period of electoral democratization. The system has strengthened Ceará's commitment to primary care even as market-oriented changes have reduced the overall role of government. The Ceará program is being copied throughout the Northeast and other regions of Brazil. The key role that nurses play in the Ceará program in organizing and leading a system of basic primary care in poor neighborhoods and rural areas may provide useful lessons for other countries. In addition, Ceará does not have many of the favorable characteristics of other countries that have successfully invested in primary health care. Ceará thus represents a

    Objectives The present study aimed to investigate the prevalence and correlates of dental caries in elderly population in northeast China. Methods A community-based, cross-sectional study among 2376 elderly subjects (age: 65–74 years) from nine urban areas and nine rural areas in three provinces of northeast China was conducted using multistage stratified random sampling per the World Health Organization oral health survey methodology. Decayed-missing-filled teeth (DMFT) and decayed-filled teeth (DFT) indices were used to evaluate the prevalence of dental caries. Face-to-face questionnaire survey on oral health was performed in a randomly selected subset (n = 1197). T test and chi square test were employed to compare groups for continuous and categorical variables, respectively. Multivariate logistic regression was used to estimate odds ratios (ORs) and corresponding confidence intervals (CIs). Results 67.5% of elderly subjects reported dental caries (average DFT = 2.68±3.40), and the prevalence was higher in urban areas (Pcaries accounted for 2.08% with a rate higher in urban areas (Pdental insurance (OR 2.050; 95% CI 1.120–3.754) with dental caries. Conclusions The prevalence of dental caries in the elderly population in northeast China is high. The elderly from urban areas who smoke and who do not have a dental insurance are at a higher risk to develop dental caries. PMID:24260129

    To describe suicide rates by county size in the five geopolitical areas of Brazil. This was an ecological, descriptive study of suicide deaths in Brazil that occurred among the population 10 years of age and older in 2004-2010. Data were obtained from the National Mortality Information System of Brazil. Counties were defined by size as: very large (200,000+), large (interval were used to compare suicide risk between groups and the reference. The national, average suicide mortality rate was 5.7 deaths/100,000 inhabitants. Except in the North and North-East, suicide mortality rates increased from the very large (> 200,000) to the micro counties ( 30 deaths per 100,000). At highest risk were micro counties in the South (13.6 deaths per 100,000), with elderly males (60+ years, 31.4) and males 40-59 years (31.3) being the sex/age group with the highest rates. To reduce suicide mortality in Brazil, public health authorities must support mental health training in small cities and multi-professional interventions among the indigenous peoples. In addition, the causes behind underreporting of suicide deaths must be resolved in several areas.

    The production of electricity using concentrated solar power (CSP) technology is not yet possible in Brazil due to the technology’s high capital costs and the lack of a local industry. However, this study introduces a low-cost approach to CSP in Brazil by describing and simulating the operation of hybrid CSP plants that use sustainably managed biomass in Brazil’s semiarid northeast. Biomass hybridisation of a CSP plant with a solar multiple (SM) of 1.2 and a biomass fill fraction (BFF) of 30% can generate electricity at 110 USD/MWh. The high direct normal irradiation (DNI) and the availability of local low-cost biomass in Brazil’s semiarid northeast suggest the possibility of developing a CSP industry capable of supplying low-cost components under a national program framework, with the co-benefits of local job and income generation. For example, the deployment of 10 CSP plants of 30 MWe each would generate 760 direct and indirect jobs during the 24 months of plant construction and approximately 2100 annual jobs associated with the operation and maintenance (O&M) of the generating units. These 10 new units would generate additional local income on the order of USD 57 million. - Highlights: • CSP plant with supplementary biomass hybridisation is a strategic option for Brazil. • DNI and biomass availability in Brazil's semiarid can foster local CSP industry. • LCOE of CSP would cost 11 cent USD/kWh becoming competitive at solar auctions. • Co-benefits of local job and income generation due to CSP in Brazil are high.

    United States policy on proliferation in Northeast Asia poses a test of balance between general US global non-proliferation goals and specific US regional security goals for Northeast Asia. US policy on proliferation in Northeast Asia further poses a test of priorities for US bilateral relations with the key Northeast Asian states, as non-proliferation and regional security goals must be weighed against other (e.g., economic, human rights) declared US policy goals. The result is a US policy equation for Northeast Asia proliferation that is considerably more complex in execution than might be expected from the simple statement of the US goal to avoid nuclear proliferation in Northeast Asia. The question of security assurances - both negative and positive - may be closely related to US policies to avoid proliferation in Northeast Asia

  12. AIDS-associated diarrhea and wasting in northeast Brazil is associated with subtherapeutic plasma levels of antiretroviral medications and with both bovine and human subtypes of Cryptosporidium parvum

    Full Text Available Advanced HIV infection is frequently complicated by diarrhea, disruption of bowel structure and function, and malnutrition. Resulting malabsorption of or pharmacokinetic changes in antiretroviral agents might lead to subtherapeutic drug dosing and treatment failure in individual patients, and could require dose adjustment and/or dietary supplements during periods of diarrheal illness. We determined the plasma levels of antiretroviral medications in patients that had already been started on medication by their physicians in an urban infectious diseases hospital in northeast Brazil. We also obtained blood samples from patients hospitalized for diarrhea or AIDS-associated wasting, and we found reduced stavudine and didanosine levels in comparison with outpatients without diarrhea or wasting who had been treated at the same hospital clinic. There was a predominance of the protozoal pathogens Cryptosporidium and Isospora belli, typical opportunistic pathogens of AIDS-infected humans, in the stool samples of inpatients with diarrhea. We conclude that severe diarrhea and wasting in this population is associated with both protozoal pathogens and subtherapeutic levels of antiretroviral medications.

  14. Developing a Crustal and Upper Mantle Velocity Model for the Brazilian Northeast

    2013-05-01

    Development of 3D models for the earth's crust and upper mantle is important for accurately predicting travel times for regional phases and to improve seismic event location. The Brazilian Northeast is a tectonically active area within stable South America and displays one of the highest levels of seismicity in Brazil, with earthquake swarms containing events up to mb 5.2. Since 2011, seismic activity is routinely monitored through the Rede Sismográfica do Nordeste (RSisNE), a permanent network supported by the national oil company PETROBRAS and consisting of 15 broadband stations with an average spacing of ~200 km. Accurate event locations are required to correctly characterize and identify seismogenic areas in the region and assess seismic hazard. Yet, no 3D model of crustal thickness and crustal and upper mantle velocity variation exists. The first step in developing such models is to refine crustal thickness and depths to major seismic velocity boundaries in the crust and improve on seismic velocity estimates for the upper mantle and crustal layers. We present recent results in crustal and uppermost mantle structure in NE Brazil that will contribute to the development of a 3D model of velocity variation. Our approach has consisted of: (i) computing receiver functions to obtain point estimates of crustal thickness and Vp/Vs ratio and (ii) jointly inverting receiver functions and surface-wave dispersion velocities from an independent tomography study to obtain S-velocity profiles at each station. This approach has been used at all the broadband stations of the monitoring network plus 15 temporary, short-period stations that reduced the inter-station spacing to ~100 km. We expect our contributions will provide the basis to produce full 3D velocity models for the Brazilian Northeast and help determine accurate locations for seismic events in the region.

    In 2010, the American Heart Association has proposed a new concept "ideal cardiovascular health" (CVH) based on seven CVH metrics: smoking, body mass index, physical activity, diet score, total cholesterol, blood pressure, and fasting plasma glucose. We aimed to determine the association of CVH with atherogenic index of plasma (AIP), a strong marker for atherosclerosis (AS). This cross-sectional study was conducted in the rural areas of northeast China and 11,113 middle-aged subjects were enrolled. Seven CVH metrics were classified into ideal, intermediate, and poor groups. AIP was calculated as log (TG/HDL) (triglycerides/high-density lipoprotein cholesterol). AIP > 0.21 was classified into the high AIP group and served as dependent variable. All seven CVH metrics were correlated with AIP. A gradient relationship between the number of poor CVH metrics and the prevalence of high AIP existed. Log binomial regression analysis showed that compared to those with five to seven ideal CVH metrics, individuals with four, three, two, one, and no ideal CVH metrics had 1.67, 2.66, 4.00, 5.30 and 6.50 times higher prevalence for high AIP. The subjects with poor CVH status had 2.73 times higher prevalence for high AIP. We found an inversely gradient relationship between the number of ideal CVH metrics and lower prevalence of high AIP.

    Residents of rural areas may have limited access to healthy foods, leading to higher incidence of diet related health issues. Smaller grocers in rural areas experience challenges in maintaining fresh produce and other healthy foods available for customers. This study assessed the rural food environment in northeast Lower Michigan in order to inform healthy food financing projects such as the Michigan Good Food Fund. The area's retail food businesses were categorized using secondary licensing, business, and nutrition program databases. Twenty of these stores were visited in person to verify the validity of the categories created, and to assess the availability of healthy foods in their aisles. In-depth interviews with key informants were carried out with store owners, economic development personnel, and other food system stakeholders having knowledge about food access, in order to learn more about the specific challenges that the area faces. Out-shopping, seasonality, and economic challenges were found to affect healthy food availability. Mid-sized independent stores were generally found to have a larger selection of healthy foods, but smaller rural groceries also have potential to provide fresh produce and increase food access. Potential healthy food financing projects are described and areas in need of further research are identified.

    Ethnobotanical studies have contributed significantly in research of plants with therapeutic potential. The aim of the present study was to learn about the use of native medicinal plants cited by the traditional population in "cerradão" (savanna woodland) areas in Northeast Brazil, providing data on therapeutic indications of the species used and their versatility. Semi-structured interviews were conducted on the basis of a standardized questionnaire designed for key informants selected using the "snowball" technique. The selection of plants species with therapeutic potential was performed on the basis of the relative importance (RI) and informant consensus fator (ICF). A total of 78 species were indicated for 87 therapeutic purposes. Of these, 11 species presented great versatility of use (RI>1), as e.g.including Copaifera langsdorffii Desf., Hybanthus calceolaria (Mart.) Plumel., Heliotropium cf. indicum L., Croton zehntneri, Croton heliotropiifolius, Myracrodruon urundeuva, Stryphnodendro rotundifolium. Medicinal uses could be generalized Pax & K. Hoffm and Hymenaea courbaril L. The therapeutic indications were grouped into 14 use 15 categories with 594 species-category combinations. The largest number of medicinal species was indicated for illnesses or undefined pain, followed by diseases associated with respiratory, digestive and genitourinaryof body systems. The factor informant consensus highlighted the agreement in the use of plants and showed that the, of which Diseases of the Nervous System and, Diseases of the Circulatory System had the greatest agreement 1.0 and 0.87 repectively, Disorders of the Visual Sensory System - Eyes and Respiratory System Disorder showed the highest agreement of use. Most of the species cited by the key informants are well known scientifically, but it is interesting that some have been studied little or not all with regard to confirming their purported medicinal properties and can contribute substantially to pharmacological

    Full Text Available This paper aims to reflect on human dignity and misthanasia in the public health system in Brazil. For this, concepts, document reviews and public data about the condition of the Brazilian population’s access to public health were all used. The indicators show the health inequalities in the country, with the north and northeast at a disadvantage both in terms of access to health and the number of available professionals. Thus, the most underserved population tends to continue to be excluded from society and impaired with respect to their human dignity.

    After more than 10 years of the Global Program to Eliminate Lymphatic Filariasis (GPELF) in Brazil, advances have been seen, but the endemic disease persists as a public health problem. The aim of this study was to describe the spatial distribution of lymphatic filariasis in the municipality of Jaboatão dos Guararapes, Pernambuco, Brazil. An epidemiological survey was conducted in the municipality, and positive filariasis cases identified in this survey were georeferenced in point form, using the GPS. A kernel intensity estimator was applied to identify clusters with greater intensity of cases. We examined 23 673 individuals and 323 individuals with microfilaremia were identified, representing a mean prevalence rate of 1.4%. Around 88% of the districts surveyed presented cases of filarial infection, with prevalences of 0–5.6%. The male population was more affected by the infection, with 63.8% of the cases (P<0.005). Positive cases were found in all age groups examined. The kernel intensity estimator identified the areas of greatest intensity and least intensity of filarial infection cases. The case distribution was heterogeneous across the municipality. The kernel estimator identified spatial clusters of cases, thus indicating locations with greater intensity of transmission. The main advantage of this type of analysis lies in its ability to rapidly and easily show areas with the highest concentration of cases, thereby contributing towards planning, monitoring, and surveillance of filariasis elimination actions. Incorporation of geoprocessing and spatial analysis techniques constitutes an important tool for use within the GPELF. PMID:22943547

  6. The technical potential for proliferation in Northeast Asian states

    1995-01-01

    This is a review of the technical capabilities of the states in Northeast Asia - principally Japan, South Korea, and North Korea - to develop nuclear weapons. At the outset, however, it should be emphasised that nuclear proliferation is primarily a political and security problem, rather than a technical challenge. The technical challenge is substantial, but if one looks at states with the technical capacity to develop nuclear weapons, it might be surprising to find that most of them have chosen not to do so. Even with access to fissile material and the technical and scientific infrastructure necessary to produce nuclear weapons, such states as Canada, Switzerland, Norway, Germany, Argentina, Brazil, Japan and many others, have not done so. All three non-nuclear weapon states in Northeast Asia have the technical capability to develop nuclear weapons. Japan and South Korea have intrusive safeguards and inspection arrangements on their nuclear programs, which allow their neighbours and the rest of the world to verify that they have not changed that status, and that they are living up to their NPT commitments. Despite its original commitment to the NPT, North Korea has yet to establish similar arrangements. It is ironic that the country with the smallest and technically least sophisticated nuclear program is the one creating the greatest concern about nuclear proliferation in the region. This irony illustrates the point made in the introduction, however. Nuclear proliferation is more a function of political decision-making than of technical capability

    Full Text Available This article outlines a New Institutional Economics’ approach of rural credit. The mainstream relies in the understanding that the rural credit contracts are hybrid forms in response to the agrichain´s complexity. The object of the research was operational credit contract for soybeans farms. The research consisted on qualitative researches in the extent that they sought to comprehend in a more profound level the rules of game for the rural financing contracting environment based on the economic agent’s perceptions. The results highlighted the agent’s perception that the judicial system is not strong enough to performance an efficient enforcement of the contracts. In response to this institutional challenge, the agents and the government manage adaptations in the contracts, which has been successful in the agent’s point of view. In the other hand, the informational system has showed weaknesses in protecting the creditor’s right. This scenario open breaches to opportunist actions and adverse selection. In order to mitigate these problems the agents govern interdependent transactions as a tool for risk sharing.

A community-based, cross-sectional study among 2376 elderly subjects (age: 65-74 years) from nine urban areas and nine rural areas in three provinces of northeast China was conducted using multistage stratified random sampling per the World Health Organization oral health survey methodology. Decayed-missing-filled teeth (DMFT) and decayed-filled teeth (DFT) indices were used to evaluate the prevalence of dental caries. Face-to-face questionnaire survey on oral health was performed in a randomly selected subset (n = 1197). T test and chi square test were employed to compare groups for continuous and categorical variables, respectively. Multivariate logistic regression was used to estimate odds ratios (ORs) and corresponding confidence intervals (CIs). 67.5% of elderly subjects reported dental caries (average DFT = 2.68±3.40), and the prevalence was higher in urban areas (Ppopulation in urban areas (OR 1.713; 95% CI 1.337-2.195), smoking (OR 1.779; 95% CI 1.384-2.288), and individuals without dental insurance (OR 2.050; 95% CI 1.120-3.754) with dental caries. The prevalence of dental caries in the elderly population in northeast China is high. The elderly from urban areas who smoke and who do not have a dental insurance are at a higher risk to develop dental caries.

    The availability and reliability of wind power depend a great deal on current and future climate conditions, which may vary in light of possible global climate change (GCC). Long-term energy planning, however, does not normally take possible future GCC into consideration, which may turn out to be a risky exercise. In the case of Brazil, the untapped wind power potential is known to be impressive, provided that climate conditions remain the same over time. The focus of this study is to analyze some possible impacts of GCC on the wind power potential of Brazil, by simulating wind conditions associated with the IPCC A2 and B2 Scenarios. Results based on the HadCM3 general circulation model and the analysis of the country's wind database indicate that the wind power potential in Brazil would not be jeopardized in the future due to possible new climate conditions. On the contrary, improved wind conditions are expected, particularly in the Northeast coast of the country. Therefore, investments in wind power generation can be an interesting way to expand renewable energy production in Brazil. However, given the large uncertainties associated with GCC models and scenarios, the findings of this paper should be viewed as a possibility rather than as a projection. (author)

  10. Circulation and teleconnection mechanisms of Northeast Brazil droughts

    Science.gov (United States)

    Hastenrath, Stefan

    2006-08-01

    The Northern Nordeste of Brazil has its short rainy season narrowly concentrated around March-April, when the interhemispheric southward gradient of sea surface temperature (SST) is weakest and the Intertropical Convergence Zone (ITCZ), which is the main rainbearing system for the Nordeste, reaches its southernmost position in the course of the year. The recurrent Secas (droughts) have a severe socio-economic impact in this semi-arid region. In drought years, the pre-season (October-January) rainfall is scarce, the interhemispheric SST gradient weakened and the basin-wide southerly (northerly) wind component enhanced (reduced), all manifestations of an anomalously far northward ITCZ position. Apart from this ensemble of Atlantic indicators, the Secas also tend to be preceded by anomalously warm equatorial Pacific waters in January. During El Niño years, an upper-tropospheric wave train extends from the equatorial eastern Pacific to the northern tropical Atlantic, affecting the patterns of upper-tropospheric topography and divergence, and hence of vertical motion over the Atlantic. The altered vertical motion leads to a weaker meridional pressure gradient on the equatorward flank of the North Atlantic subtropical high, and thus weaker North Atlantic tradewinds. The concomitant reduction of evaporation and wind stirring allows for warmer surface waters in the tropical North Atlantic and thus steeper interhemispheric meridional thermal gradient. Consequently, the ITCZ stays anomalously far North and the Nordeste rainy season becomes deficient.

    1999-12-01

    In Northeast Asian region, there are East Russia with abundant resources, Japan a large energy consumption country, Korea and China with rapidly increasing energy consumption due to their economic development, but the utilization rate of East Russian resources are very low and the resource trading and investment among Korea, China and Japan are also low. Korea and Japan use most of energy imported from Middle East. It is expected that import of petroleum and gas except coal will be increasing in China and most of imported energy will be imported mainly from the Middle East. For Korea, with not much energy resources and foreign-oriented economic system, if investment on resource development among Northeast Asian countries is active and energy transportation among these countries is liberalized, the enhancement of energy cooperation in Northeast Asia has a high possibility to provide North and South Korean energy cooperation as well as to secure energy security and to develop energy industry. Therefore, Korean government needs to promote Northeast Asian energy cooperation by taking its lead. (author). 28 refs., 8 figs., 44 tabs.

    Each summer period extremely high ozone levels are registered at the rural background station of Lamas d’Olo, located in the Northeast of Portugal. In average, 30% of the total alert threshold registered in Portugal is detected at this site. The main purpose of this study is to characterize the atmospheric conditions that lead to the ozone-rich episodes. Synoptic patterns anomalies and back trajectories cluster analysis were performed for a period of 76 days where ozone maximum concentrations were above 200 µg.m-3. This analysis was performed for the period between 2004 and 2007. The obtained anomaly fields suggested that a positive temperature anomaly is visible above the Iberian Peninsula. In addition, a strong wind flow pattern from NE is visible in the North of Portugal and Galicia, in Spain. These two features may lead to an enhancement of the photochemical production and to the transport of pollutants from Spain to Portugal. In addition, the 3D mean back trajectories associated to the ozone episode days were analysed. A clustering method has been applied to the obtained back trajectories. Four main clusters of ozone-rich episodes were identified, with different frequencies of occurrence: north-westerly flows (11%); north-easterly flows (45%), southern flow (4%) and westerly flows (40%). Both analyses highlight the NE flow as a dominant pattern over the North of Portugal. The analysis of the ozone concentrations for each selected cluster indicates that this northeast circulation pattern, together with the southern flow, is responsible for the highest ozone peak episodes. This also suggests that long-range transport of atmospheric pollutants may be the main contributor to the ozone levels registered at Lamas d’Olo. This is also highlighted by the correlation of the ozone time series with the meteorological parameters analysed in the frequency domain.

    The efficiency for carbonization by slow pyrolysis is still low in the current method studied using rice straw in Thailand and cashewnut shell in Brazil, however direct heating process yields better char yield of 17% as compared to indirect heating with 15% process using horizontal metal drum kiln.where as vertical kiln were mainly used in Brazil. Higher yield is made possible from Brasilian cashew nut shell to make oil and char. Carbon and energy balance was also carried out and the results were compared for the direct and indirect process. Burning by indirect draft gives better results like more char, faster process. Direct draft gives less char, but higher quality (higher C and H2). Also a lot of straw is left unburnt in the direct draft kiln, because of bad temperature distribution and flow inside. The kiln design is found to be more suitable for indirect draft rather than direct draft. Both methods still give rice straw charcoal that has low calorific value with an output char LHV of 4337 kcal/kg as compared to fresh rice straw of 3412 kcal/kg. In the direct heating method output char is enriched to 45% with a still unburnt rice straw left out as compared to indirect heating method with carbon enrichment of 39%. There is a loss of 13% of carbon through the ash in the both the methods. The carbon content in the condensate is in the order of 18.5% for the indirect process as compared to 13.9% in the direct process due to less exhaust and carbon enrichment inside the kiln. There is a loss of 43% of carbon in the exhaust from indirect heating process as compared to direct heating process which is reduced to 26%. The energy balance predicts a heat loss of 14% in exhaust gases. A practical small scale slow pyrolysis project was developed to meet rural energy and heat requirements. to make the clean energy from waste resources possible by the joint project. (author)

  15. Governance in agribusiness organizations: challenges in the management of rural family firms

    Cláudio Pinheiro Machado Filho

    Full Text Available Abstract The rural production in Brazil has experienced a significant competitive impact with the stabilization of the economy promoted by the Real Plan in 1994. Indeed, the Brazilian agriculture has achieved efficiency gains in terms of technology, economies of scale and general modernization of the activity in the field. In this context, the professional management of rural production evolved. However, the governance process does not evolve in the same dimension, and the “governance risk” is still poorly addressed in the rural environment, which often limits the potential of operations. In this study, we sought to deepen the understanding of the factors that impact the implementation of governance practices in rural properties in Brazil. Based on a convenience and non-probability sample, this study seeks to understand the evolution of the governance process on farms and its correlation with the management practices. This study found a correlation between the existence of some formal management processes (for example, strategic planning and more robust accounting systems and advances in the governance mechanisms and processes, such as the establishment of a board of directors, clearer rules regarding the separation between corporate and family assets and more transparency in income statements. This study also found a lack of clarity in the separation of return on capital (dividend and compensation for work (compensation for services provided for partners, heirs and other family members. In summary, we concluded that there is the adoption of some governance mechanisms in the rural sector, but they are still poorly developed among rural producers, hence the need to stimulate them.

    In Brazil, the National Ordinance No. 453/1998 of the Ministry of Health regulates the operation of medical and odontological diagnostic radiology services. However, the inspection of periapical dental X-ray equipment is not carried out by some Sanitary Surveillances. This study intended to determine the suitability to the ordinance of the dental offices of Sobral-CE, Northeast of Brazil, and to compare the results with literature data for other cities of Brazil, giving a view of dental radiology of this country. It was performed tests of radiation field and image quality, and it was applied questionnaires to the professionals of Sobral-CE. For the image quality test, it was used a dental phantom and the processing of the films was performed in the clinics and at the laboratory (standard). The questionnaire assessed physical parameters that interfere on the radiation protection and on the quality of images. The results show that the ordinance is not being properly followed and that it is necessary to inspect the periapical X-ray equipments. Moreover, in general, it is observed that dental professionals should have better training on ionizing radiation and on radiation protection. (authors)

    The extraction and recobery of uranium contained in marine phosphates of northeast Brazil were investigated by treating ores with hydrochloric acid. The average content of uranium in the ore was found to be about 0,03 percent which corresponds to the highest worldly known content of uranium in phoshorite. The solutions obtained in laboratory, by leaching the phosphorite with hydrochloric acid, contained 40-70mg U/1. A method to control the uranium solubilization was outlined. A liquid-liquid extrction of uranium from these liquors was performed using a mixture of 3 percent di (2-ethyl hexyl)-phosphoric acid and 2.2 percent TBP in Kerosene. An overall uranium recovery of about 85 percent was reached

    Full Text Available CONTEXT: Brazilian infant and child mortality levels are not compatible with the country's economic potential. In this paper, we provide a description of levels and trends in infant mortality due to perinatal causes and malformations and assess the likely impact of changing intermediate-level determinants, many of which are amenable to direct interventions through the health or related sectors. TYPE OF STUDY: Review paper. METHODS: Two main sources of mortality data were used: indirect mortality estimates based on censuses and surveys, and rates based on registered deaths. The latter were corrected for under-registration. Combination of the two sources of data allowed the estimation of cause-specific mortality rates. Data on current coverage of preventive and curative interventions were mostly obtained from the 1996 Demographic and Health Survey. Other national household surveys and Ministry of Health Statistics were also used. A thorough review of the Brazilian literature on levels, trends and determinants of infant mortality led to the identification of a large number of papers and books. These provided the background for the analyses of risk factors and potential interventions. RESULTS: The indirect infant mortality rate estimate for 1995-97 is of 37.5 deaths per thousand live births, about six times higher than in the lowest mortality countries in the world. Perinatal causes account for 57% of all infant deaths, and congenital malformations are responsible for 11.2% of these deaths. Mortality levels are highest in the Northeast and North, and lowest in the South and Southeast; the Center-West falls in between. Since surveys of the North region do not cover rural areas, mortality for this region may be underestimated. CONCLUSIONS: A first priority for the further reduction in infant mortality in Brazil is to improve equality among regions, since the North and Northeast, and particularly rural areas, still show very high death rates.

    Full Text Available Ehrlichiosis is a zoonotic disease that is caused by bacteria of the genus Ehrlichia. The aims of this study were to detect the presence of Ehrlichia spp. in the blood of dogs in Ituberá, Bahia, and to compare the sensitivities and specificities of blood smear, serological, and molecular examinations. Furthermore, this study identified factors associated with exposure to the agent in dogs in this locality. Blood samples were collected from 379 dogs and submitted for indirect immunofluorescent assay and polymerase chain reaction testing for the detection of Ehrlichia spp. antibodies and DNA, respectively. Additionally, a peripheral blood smear was obtained from the ear tip for parasite identification. Of the 379 animals, 12.4%, 32.7%, and 25.6% were identified as positive on the blood smear, serological, and molecular tests, respectively. The dogs positive in one of the three techniques were considered exposed (46.9%. Younger dogs and rural habitat were protective factors and presence of ticks and contact with other dogs were the risk factors associated with exposure to the agent. It was concluded that dogs of Ituberá have high positivity for Ehrlichia spp. and that the diagnostic methods used for detection are complementary.

    Population and reproductive biology of Uca thayeri Rathbun, 1900 were studied for the first time in a tropical mangrove. Absolute density, sex ratio, population structure, handedness, breeding season and fecundity were investigated. Seven transects were delimited in a mangrove area of the Pacoti River, Northeast of Brazil (3° 43' 02″ S/38° 32' 35″ W). On each transect, ten 0.25 m 2 squares were sampled on a monthly basis during low tide periods from September 2003 to August 2004. A total of 483 crabs were obtained, of which 250 were males, 219 non-ovigerous females, and 14 ovigerous females. The U. thayeri population presented bi-modal size frequency distribution, with males and non-ovigerous females not differing significantly size-wise. Ovigerous females were larger than males and non-ovigerous females. The overall sex ratio (1:1.07) did not differ significantly from the expected 1:1 proportion. The major cheliped was the right one in 50% of the males. The observed density was of 8.5 individuals/m 2, with the specimens being found mostly in shaded areas. Ovigerous females were found in 5 months of the year, coinciding with the rainy season, suggesting that the population of U. thayeri presents seasonal reproductive events. Juvenile crabs were more abundant during the dry period, while larger crabs were found mainly during the rainy period. The fecundity of the studied population was much smaller than that of subtropical populations of this species. The regression analysis shows that the number of eggs increases linearly with the increase of carapace width.

  2. An integrated geological and geophysical study of the Parnaíba cratonic basin, North-East Brazil

    Cratonic basins are characterized by their sub-circular shape, long-lived (>100 Myr) subsidence, shallow marine/terrestrial sediments that young towards the center of the basin and exhibit little internal deformation, and thick seismic lithosphere. Despite the recognition of >30 world-wide, the paucity of geological and geophysical data over these basins means their origin remains enigmatic. In order to address this problem, we have used a recently acquired 1400 km long seismic reflection profile recorded to 20 s TWTT, field observations and well logs, gravity and magnetic data acquired at 1 km intervals, and five wide-angle refection/refraction receiver gathers recorded at offsets up to 100 km, to constrain the origin of the Parnaíba basin, North-East Brazil. We find a depth to pre-Paleozoic basement and Moho of ~ 3.5 and ~ 40 - 42 km respectively beneath the basin center. A prominent mid-crustal reflection (MCR) can be tracked laterally for ~ 300 km at depths between 17 - 25 km and a low-fold wide-angle receiver gather stack shows that the crust below the MCR is characterized by a ~ 4 s TWTT package of anastomosing reflections. Gravity modelling suggests that the MCR represents the upper surface of a high density (+0.14 kg m-3) lower crustal body, which is probably of magmatic origin. Backstripping of biostratigraphic data from wells in the center of the basin show an exponentially decreasing subsidence. We show that although cooling of a thick (180 km) lithosphere following prolonged rifting (~ 65 Myr) can provide a good fit to the tectonic subsidence curves, process-oriented gravity and flexure modelling suggest that other processes must be important, as rifting does not account for the observed gravity anomaly and predicts too thin a crust (~ 34 km). The thicker than expected crust suggests warping due, for example, to far-field stresses or basal tractions. Another possibility, which is compatible with existing geophysical data, is a dense magmatic intrusion

    The burden of sexually transmitted infections (STIs), such as syphilis, is higher in low-income countries, with serious consequences and profound impact on sexual and reproductive health and human immunodeficiency virus (HIV) spread. Syphilis prevalence tend to be higher among people who misuse drugs than in the general population. To assess syphilis and associated factors among polydrug users (PDU) in the city of Salvador, Northeast Brazil. A cross-sectional study was conducted in 10 Brazilian cities between September and November 2009 using Respondent Driven Sampling (RDS). Participants answered an Audio Computer-Assisted Self Interview (ACASI) and were rapid tested for HIV and syphilis. We performed multivariable regression models for correlates of syphilis on Stata 10.0. Estimates were weighted by the inverse size of the individual social network size and homophily. Mean age was 29.3 years (range: 18-62), 74.0% were males, and 89.8% were non-white. Syphilis prevalence was 16.6%. Females (adjwOR:2.14; 95%CI:1.09-4.20), individuals over 29 years old (adjwOR:4.44; 95%CI:2.41-8.19), those who exchanged sex for money or drugs (adjwOR:3.51; 95%CI:1.84-6.71), "No/low" self-perceived risk of HIV infection (adjwOR:5.13; 95%CI:1.36-19.37), and having nine or less years of education (adjwOR:2.92; 95%CI:1.08-7.88) were associated with syphilis. One of the most pressing needs for syphilis prevention/control is the availability of rapid point-of-care diagnostic tests and treatment. Interventions should be tailored to PDU needs and their multiple burdens as shown in the present study, that may contribute to future studies aiming to better understand the relationships between drug use and syphilis.

    To evaluate the frequency of teenage pregnancy in Brazil, from 2000 to 2011, in all five Brazilian macroregions and age groups (10-14 and 15-19 years), correlating it with the human development index (HDI). Descriptive epidemiological study, with cross-sectional design, performed by searching the database of the National Health System (Datasus), using information from the Information System (Sinasc). There was a decrease in the percentage of live births (LB) from teenage mothers (10-19 years) in Brazil (23.5 % in 2000 to 19.2 % in 2011). This reduction was observed in all Brazilian macroregions in the group of mothers aged 15 to 19 years. The number of LB increased by 5.0% among mothers aged 10-14 years (increase in the North and Northeast and decline in the other macroregions). The proportion of LB shows an inversely proportional trend to HDI score, with the Southeast having the highest HDI and the lowest proportion of LB to teenage mothers in the country. Brazil shows a decline in the percentage of LB to adolescent mothers, tending to be inversely related to HDI score. It is important to empower strategies to address the problem, so that teenage pregnancy is seen as a personal decision rather than the result of a lack of policies targeting adolescent health.

    This study investigates the relationship between political consumerism and core political values (CPVs) among university students in Brazil (N = 414) and Germany (N = 222). Despite the prerequisite to endorse values that are compatible with political consumerism, contextual features of one's immediate environment might affect overall levels of political consumerism. Our results show that political consumerism is significantly associated with higher income in Brazil (but not in Germany). After controlling for income, political consumerism was practised more frequently in Germany than in Brazil, in urban compared with rural areas, and was not dependent on gender. The urban-rural split was stronger in Brazil than in Germany. These results confirm our hypothesis that contextual features are associated with political consumerism. Furthermore, the political value Equality positively predicted political consumerism in both countries. In contrast, Traditional Morality and support of Free Enterprise negatively predicted political consumerism, although the effect sizes of these relationships were only small. These results suggest that political consumerism among university students is widespread in Germany but not in Brazil. Interestingly, regardless of its low prevalence in Brazil, political consumerism is positively associated with the CPV of Equality among university students in both countries. © 2015 International Union of Psychological Science.

    Full Text Available Background: Several studies have investigated the prevalence and awareness of diabetes mellitus (DM in China, but little is known about the situation of DM in the northeastern rural areas. Our present study investigated the prevalence, awareness and associated characteristics of DM in rural areas of Jilin Province, aiming to suggest more efforts for the prevention and control of DM. Methods: A multistage stratified random cluster sampling design was used in this cross-sectional study which took place in 2012. Data were collected by face-to-face interviews and physical examinations. Rao-Scott Chi-square test, t test and multivariate logistic regression analysis were used. Results: The estimated prevalence of DM in rural areas of Jilin province was 7.2%. DM was positively associated with age, Body mass index (BMI, hypotension, dyslipidemia and was high in participants with a family history of diabetes and those who exercise frequently, but low for high education level and married participants. 69.0% participants with DM were aware of their diabetes status, 88.2% of whom received treatment and 34.4% of whom had received treatment controlled their DM status. Conclusions: We observed a high prevalence and low awareness status of DM among the rural residents in Jilin Province, but the rate of effective control in those who have received treatment was considerable. The low rate of disease surveillance should draw health authority’s attention.

    Full Text Available In Britain the conflict between the national standard and regional languages and varieties, or rather those perceived to be ‘only’ a dialect, is still going strong and Scots plays a peculiar role in it. It is recognised and afforded a certain level of protection and promotion under the European Charter for Regional and Minority Languages (ECRML. While related to English, Scots has a number of regional varieties and it stands in competition with other varieties of English within Scotland. North-East Scots (NE Scots, also known as ‘the Doric’, in particular occupies a rather special place within the sphere of Scots. While research has often focused on the perceived status of urban versus rural Scots, this paper examines the attitudes towards NE Scots with regard to identity construction as displayed by its speakers in rural areas and small towns in the North-East. Another focal point is the use of the regional variety as a perceived act of resistance against the ostensible dominance of English. Within the mind of its speakers what kind of identity do they feel they have - a largely local/regional, a national Scottish, a British one or something entirely different? The analysis of interview data highlights that respondents’ statements and their actual linguistic behaviour reinforce the affirmation of their regional identity; the extent to which this occurs will also be investigated.

    Benchimol, J L

    2008-12-01

    Medical Entomology emerged in Brazil in the late nineteenth century, through the initiative of a group of physicians dedicated to researching microorganisms related to diseases of public health importance, especially yellow fever and malaria. They led the institutionalization of Bacteriology and Tropical Medicine in southeast Brazil and the sanitation of coastal cities and, subsequently, rural areas. Medical Entomology provided the professionals who would undertake campaigns against agricultural plagues, as well as the institutionalization of Agronomy and Veterinary Medicine. In the present article, I intend to show how relations between the professionals who gave life to Medical Entomology in Brazil were interwoven and to illustrate their relations with entomologists in other countries. I will also present an overview of the research problems faced by Brazilian entomologists at the turn of the nineteenth century and early decades of the twentieth.

    In many developing countries overweight, obesity and obesity-related morbidity are becoming a problem of increasing public health importance. The purpose of this study was to investigate differences in body size and body composition with age in adults of the Caboclo populations from the Brazilian Amazon as well as to examine the prevalence of overweight and obesity in adults aged 20-75 years, taking into account recent trends for the whole country. Caboclo are genetically and culturally admixed rural peasant groups that live along the Amazon River and its tributaries in Brazil, and there are few previous studies of their health and lifestyle. A total of 304 subjects (149 males and 155 females) from two socioecologically different areas were studied. Height, weight and skinfolds (tricipital, subscapular and suprailiac) were measured; international intervals (WHO) for overweight and obesity were used. Women showed significantly lower values than men for height, weight, upper arm circumference and fat-free mass and higher values for triceps, subscapular and suprailiac skinfolds and body fat (%). In the overall sample combined overweight and obesity was 47.8% in men and 50.8% in women. When compared to recent values published for the Northern region and for the whole of Brazil, 20.5% of Caboclo women aged 20-75 years were obese, which is higher than all other populations, including other rural samples. Caboclo men showed the highest rates of obesity (9.1%) and overweight (39.1%) of any rural population from the country, including Northern Brazil. The results suggest an effect of increased Western lifestyle influence on the body composition of these Caboclo populations. Considering that these are rural populations with limited access to education and health care, the high prevalence of overweight and obesity associated with low socio-economic status makes them a vulnerable group that deserves a higher level of attention by the country's public health authorities.

    Each summer period extremely high ozone levels are registered at the rural background station of Lamas d'Olo, located in the Northeast of Portugal. In average, 30% of the total alert threshold registered in Portugal is detected at this site. The main purpose of this study is to characterize the atmospheric conditions that lead to the ozone-rich episodes at this site. Synoptic patterns anomalies and back trajectories cluster analysis were performed, for the period between 2004 and 2007, considering 76 days when ozone maximum hourly concentrations were above 200 μg m -3. The obtained atmospheric anomaly fields suggested that a positive temperature anomaly is visible above the Iberian Peninsula. A strong wind flow pattern from NE is observable in the North of Portugal and Galicia, in Spain. These two features may lead to an enhancement of the photochemical production and to the transport of pollutants from Spain to Portugal. In addition, the 3D mean back trajectories associated to the ozone episode days were analysed. A clustering method has been applied to the obtained back trajectories. Four main clusters of ozone-rich episodes were identified, with different frequencies of occurrence: north-westerly flows (11%); north-easterly flows (45%), southern flow (4%) and westerly flows (40%). Both analyses highlight the NE flow as a dominant pattern over the North of Portugal during summer. The analysis of the ozone concentrations for each selected cluster indicates that this northeast circulation pattern, together with the southern flow, are responsible for the highest ozone peak episodes. This also suggests that long-range transport of atmospheric pollutants is the main contributor to the ozone levels registered at Lamas d'Olo. This is also highlighted by the correlation of the ozone time-series with the meteorological parameters analysed in the frequency domain.

  20. A new order in northeast Asia

    The fate of northeast Asia is central to the global balance of power. But just as the Cold War took a different course in northeast Asia than it did in its central battleground in Europe, so the post-Cold War world in northeast Asia is taking on a different shape. In Europe, formal arms control was a feature of the political landscape both before and after sweeping changes began altering the face of the continent in 1989. In contrast, northeast Asia saw only informal arms control measures before 1989. But in the post-Cold War world, the opportunity for more formal accords seems to be growing as the changing political environment makes them possible. In the rapidly developing virtuous circle of detente in northeast Asia, the prospects for arms control progress are better than ever, although considerable obstacles remain in the way. One of the unique features of northeast Asia is the convergence of interests of four of the world's most powerful nations - the US, the Soviet Union, Japan, and China. But unlike Europe, where the interests of the Soviet Union and the US have intermingled with those of the diverse members of the European Community (EC) and resulted in far-reaching arms reduction and confidence-building accords, northeast Asia has known only limited regional efforts at reducing tension and enhancing regional security. Nevertheless, unilateral moves and bilateral discussions among the four powers have produced a Sino-Soviet detente, reductions in US and Soviet forces in the Pacific region, the beginning of a Soviet-Japanese dialogue aimed at normalizing relations, and an overall trend toward closer diplomatic and economic relations throughout the region

    Full Text Available Observations (1978–1991 of distributions of pelagic juvenile Northeast Arctic cod (Gadus morhua L. show that up to 1/3 of the year class are dispersed off the continental shelf and into the deep Norwegian Sea while on the way from the spring-spawning areas along the Norwegian coast to the autumn-settlement areas in the Barents Sea. The fate of this variable fraction of pelagic juveniles off-shelf has been an open question ever since Johan Hjort's (1914 seminal work. We have examined both the mechanisms causing offspring off-shelf transport, and their subsequent destiny using an individual-based biophysical model applied to quantify growth and dispersal. Our results show, consistently with the observations, that total off-shelf transport is highly variable between years and may be up to 27.4%. Offspring from spawning grounds around Lofoten have a higher chance of being displaced off the shelf. The off-shelf transport is dominated by episodic events where frequencies and dates vary between years. Northeasterly wind conditions over a 3–7-day period prior to the off-shelf events are a good proxy for dispersal of offspring off the shelf. Offspring transported into the open ocean are on average carried along three following routes: back onto the adjacent eastern shelves and into the Barents Sea (36.9%, recirculating within the Lofoten Basin (60.7%, or drifting northwest to the northeast Greenland shelf (2.4%. For the latter fraction the transport may exceed 12% depending on year. Recent investigations have discovered distributions of young cod on the northeast Greenland shelf indicating that conditions may support survival for Northeast Arctic cod offspring.

    Full Text Available Ectomycorrhizal macromycetes are, generally, an important ecological component for forest habitats, and a valuable resource in the context of sustainable development of rural communities in the North-East Region of Romania. The woody species distribution is an extremely important factor for the ECM macromycetes presence. The purpose of this study was to elaborate maps of potential distribution for some ECM edible macromycetes from Russula and Lactarius genera, based on chorological information, ICAS Forest Types Map, vegetation tables and bibliographical sources. These information allowed the elaboration of 15 potential maps of distribution for 15 edible species of Russula and Lactarius. The study was based entirely on the plant – fungal associations. The results highlighted that in the North-East Region of Romania there is a noteworthy potential for Russulaceae species. As expected, there is a large amplitude of species presence in the field depending on the fungal specificity for tree host and tree species distribution.

    The characteristics of aerosol particles have been poorly evaluated even though haze episodes frequently occur in winter in Northeast China. OC/EC analysis, ion chromatography, and transmission electron microscopy (TEM) were used to investigate the organic carbon (OC) and elemental carbon (EC), and soluble ions in PM 2.5 and the mixing state of individual particles during a severe wintertime haze episode in Northeast China. The organic matter (OM), NH 4 + , SO 4 2- , and NO 3 - concentrations in PM 2.5 were 89.5 μg/m 3 , 24.2 μg/m 3 , 28.1 μg/m 3 , and 32.8 μg/m 3 on the haze days, respectively. TEM observations further showed that over 80% of the haze particles contained primary organic aerosols (POAs). Based on a comparison of the data obtained during the haze formation, we generate the following synthetic model of the process: (1) Stable synoptic meteorological conditions drove the haze formation. (2) The early stage of haze formation (light or moderate haze) was mainly caused by the enrichment of POAs from coal burning for household heating and cooking. (3) High levels of secondary organic aerosols (SOAs), sulfates, and nitrates formation via heterogeneous reactions together with POAs accumulation promoted to the evolution from light or moderate to severe haze. Compared to the severe haze episodes over the North China Plain, the PM 2.5 in Northeast China analyzed in the present study contained similar sulfate, higher SOA, and lower nitrate contents. Our results suggest that most of the POAs and secondary particles were likely related to emissions from coal-burning residential stoves in rural outskirts and small boilers in urban areas. The inefficient burning of coal for household heating and cooking should be monitored during wintertime in Northeast China. Copyright © 2017 Elsevier Ltd. All rights reserved.

  4. Nuclear policies in Northeast Asia

    1995-01-01

    In Northeast Asia, states have tried to enhance their security through unilateral means rather than cooperative ones. In this area, there is no regional multilateral security dialogue of significance. In the nuclear age, security is not something to be built for oneself irrespective of others. Security is something to be built together with one's opponents. The arms build-up in Northeast Asia is very substantial. Defence budgets are growing almost as fast as are the national economies. Still, there is no arms race, i.e. no interacting patterns of arms acquisitions and force deployments. There is a real risk, however, that the arms build-up might spill over into an arms race. Hence the case for cooperative policies - for confidence-building measures and arms control in particular - to prevent this from happening. The end of the Cold War has brought about profound changes in the international political and economic environment. There is a noticeable tendency towards political reconciliation and cooperation among states and an increasing interdependence and globalization. On the other hand, one cannot miss some worrisome phenomena, including the resurgence of nationalism, the multiplication of ethnic conflicts and the dangers associated with the proliferation of weapons of mass destruction. This is particularly true of the Northeast Asian region. Although some changes in the regional security outlook are favourable, there are also sources of insecurity and uncertainty in Northeast Asia, not least being the disturbing trend towards a regional arms build-up. In today's Northeast Asia weapons proliferation is a source of growing concern. The major purpose of this volume is to provide a comprehensive analysis of the dimensions of the various nuclear problems and their interrelationships in Northeast Asia. A second purpose is to explore practical approaches to regional non-proliferation, to see how they may be strengthened and made mutually supportive of the global non

    To determine the effect of employment in childhood on self-reported health in adulthood. A cross-sectional household survey, with households selected through two-stage sampling, in urban and rural areas in the northeast and southeast of Brazil. A total of 4940 individuals, aged between 18 and 65 years, were included. The main outcome measure was self-reported health. There has been a marked reduction in the proportion of people starting work during childhood although, even in the youngest age group, nearly 20% of males began work when under 10. Early entrance into the labour market is strongly associated with low levels of both education and income, with income differentials remaining at later ages. Age starting work is also linked to current household income, with approximately 35% of those starting work when 15 or over currently in the top quartile of household income, compared with 12% of those starting work when under 10. Males, those living in rural areas, and non-whites are most likely to start work early. In univariate analyses, the younger a person started working, the greater the probability of reporting less than good health status as an adult. This persists through all ages, although the difference attenuates with increasing age. In multivariate analyses, adjustment for education or household income substantially reduces the effect but fails to eliminate it in several age bands up to the age of 48, indicating that age starting work has an independent effect on self-reported health in adulthood. The debate about the appropriate policy response to child labour is complex, requiring a balance between protecting the health of the child and safeguarding the income of the family. These findings indicate the need for more research on the long-term sequelae of beginning work at an early age.

    Background Like many other low- and middle-income countries, India faces challenges of recruiting and retaining health workers in rural areas. Efforts have been made to address this through contractual appointment of health workers in rural areas. While this has helped to temporarily bridge the gaps in human resources, the overall impact on the experience of rural services across cadres has yet to be understood. This study sought to identify motivations for, and the challenges of, rural recruitment and retention of nurses, doctors and specialists across types of contract in rural and remote areas in India's largely rural north-eastern states of Meghalaya and Nagaland. Methods A qualitative study was undertaken, in which 71 semi-structured interviews were carried out with doctors (n = 32), nurses (n = 28) and specialists (n = 11). In addition, unstructured key informant interviews (n = 11) were undertaken, along with observations at health facilities and review of state policies. Data were analysed using Ritchie and Spencer's framework method and the World Health Organization's 2010 framework of factors affecting decisions to relocate to, stay in or leave rural areas. Results It was found that rural background and community attachment were strongly associated with health workers' decision to join rural service, regardless of cadre or contract. However, this aspiration was challenged by health-systems factors of poor working and living conditions; low salary and incentives; and lack of professional growth and recognition. Contractual health workers faced unique challenges (lack of pay parity, job insecurity), as did those with permanent positions (irrational postings and political interference). Conclusion This study establishes that the crisis in recruiting and retaining health workers in rural areas will persist until and unless health systems address the core basic requirements of health workers in rural areas, which are related to health-sector policies

    Surface O 3 was monitored continuously during Aug. 12, 2010 to Jul. 21, 2011 at a high elevation site (3200 m above sea level) in Qinghai Lake area (36°58′37″N, 99°53′56″E) in Northeast Tibetan Plateau, China. Daily average O 3 ranged from 21.8 ppbv to 65.3 ppbv with an annual average of 41.0 ppbv. Seasonal average of O 3 followed a decreasing order of summer > autumn > spring > winter. Diurnal variations of O 3 showed low concentrations during daytime and high concentrations during late night and early morning. An intensive campaign was also conducted during Aug. 13–31, 2010 to investigate correlations between meteorological or chemical conditions and O 3 . It was found that O 3 was poorly correlated with solar radiation due to the insufficient NO x in the ambient air, thus limiting O 3 formation under strong solar radiation. In contrast, high O 3 levels always coincided with strong winds, suggesting that stratospheric O 3 and long range transport might be the main sources of O 3 in this rural area. Back-trajectory analysis supported this hypothesis and further indicated the transport of air masses from northwest, northeast and southeast directions. - Highlights: • Surface O 3 was measured in Qinghai Lake area in Northeast Tibetan Plateau, China. • The O 3 chemical formation was under a strong NOx-limited in Qinghai Lake areas. • Stratospheric O 3 and transport might be the main sources of O 3 in this area

    Full Text Available Two contiguous villages in Tracunhaém county (State of Pernambuco, endemic for schistosomiasis, were studied: Itapinassu (138 inhabitants and São Joaquim (91 inhabitants. Agriculture predominates in the former region while ceramics is the main activity in the latter. Although no statistical difference was found regarding prevalence, severe infection (>400 epg predominated in Itapinassu, probably related to the kind of occupation. No association was found between parasite burden and severity of disease, in spite of the high infection rates for Schistosoma mansoni in both communities (approx. 60%. Typical epidemiological features of schistosomiasis such as age-related prevalences and intensities of infection (high in children, low in adults were also mutual characteristics. Nutritional status determined through anthropometric evaluation was carried out by measuring specific anthropometric indicators. A deficit of energy intake, as well as vitamin A and riboflavin deficiencies were detected. The prevalence of moderate or severe undernutrition in patients under 18 years old was 21.9% in Itapinassu and 24.1% in São Joaquim. In this group an association was found between prevalence of schistosomiasis and chronic undernutrition. Similarly, for patients over 18 year old the prevalence of undernutrition was higher than 20%. However, in this case no association between nutritional status and either prevalence of schistosomiasis or parasite burden could be detected. The two communities had not been treated for eight years.

    Energy access has been singled out by the AGECC in 2010 as one of the important problems to be tackled in the next few decades in a world where 1.3 billion people do not have access to electricity and 2.7 use primitive fuels – mainly fuel wood – for cooking and heating. To solve such problems, innumerous small scale projects have been implemented around the world either on the improvement of cooking stoves, biogas and others, as well as in generating electricity in decentralized systems. We discuss here the “large scale approach” to solve these problems in Brazil through the introduction of LPG (liquid petroleum gas) in Brazil 70 years ago, all over the country, as a cooking fuel that replaced significantly the use of fuel wood in rural areas. In addition to that, we describe the governmental program (Luz para Todos – LPT – Light for all) introduced more recently to extend the electricity grid to around 10 million people, reducing considerably the number of people without access to electricity in the rural areas of the country. Such experiences and the corresponding lessons learned could be replicated in other developing countries, contributing significantly to poverty alleviation. - Highlights: • Energy access is one important problem for 1.3 billion people not having access to electricity and 2.7 billion using primitive fuels for cooking-heating. • We discuss the approach introduced in Brazil through the introduction of LPG as a cooking fuel that replaced significantly the use of fuel wood in rural areas. • We describe the program introduced to supply electricity, reducing the number of people without access to electricity in rural areas. • Lessons learned could be replicated in other DCs, contributing to poverty alleviation

    Full Text Available Amphoroid taxa have been revised in recent decades. Many species formerly assigned to Amphora have been transferred to other recently proposed genera, as Seminavis (Naviculaceae and Halamphora (Catenulaceae. In Brazil, there are few studies focused on amphoroid taxonomy. This study presents a taxonomic investigation of five uncommon amphoroid taxa from Brazilian diatom flora: Seminavis pusilla, S. strigosa, Amphora ectorii, Halamphora ghanensis and Halamphora sp. Seminavis strigosa is identical in valve morphology and morphometrical data to Amphora twenteana, and its synonymy is proposed. Seminavis pusilla, poorly found in Brazilian waters, has expanded its distribution. Halamphora ghanensis is a new record to American continent while Amphora ectorii are new to Brazilian aquatic systems. Halamphora sp. has distinct ultrastructural features in relation to similar species and is probably new for science.

    Full Text Available We aimed to compare the relative strength of the association between anthropometric obesity indices and chronic kidney disease (CKD. Another objective was to examine whether the visceral adiposity index (VAI and lipid accumulation product index (LAPI can identify CKD in the rural population of China. There were 5168 males and 6024 females involved in this cross-sectional study, and 237 participants (2.12% suffered from CKD. Obesity indices included body mass index (BMI, waist circumference (WC, waist-to-height ratio (WHtR, VAI and LAPI. VAI and LAPI were calculated with triglyceride (TG, high-density lipoprotein (HDL, BMI and WC. VAI = [WC/39.68 + (1.88 × BMI] × (TG /1.03 × (1.31/ HDL for males; VAI = [WC/36.58 + (1.89 × BMI] × (TG/0.81 × (1.52/HDL for females. LAPI = (WC-65 × TG for males, LAPI = (WC-58 × TG for females. CKD was defined as an estimated glomerular filtration rate (eGFR of less than 60 mL/min per 1.73 m2. The prevalence of CKD increased across quartiles for WHtR, VAI and LAPI. A multivariate logistic regression analysis of the presence of CKD for the highest quartile vs. the lowest quartile of each anthropometric measure showed that the VAI was the best predictor of CKD in females (OR: 4.21, 95% CI: 2.09–8.47, p < 0.001. VAI showed the highest AUC for CKD (AUC: 0.68, 95% CI: 0.65–0.72 and LAPI came second (AUC: 0.66, 95% CI: 0.61–0.70 in females compared with BMI (both p-values < 0.001. However, compared with the traditional index of the BMI, the anthropometric measures VAI, LAPI, WC, and WHtR had no statistically significant capacity to predict CKD in males. Our results showed that both VAI and LAPI were significantly associated with CKD in the rural population of northeast China. Furthermore, VAI and LAPI were superior to BMI, WC and WHtR for predicting CKD only in females.

    Full Text Available Abstract The aim of this study was to describe the first records of termite activity on non-fossilized human bones in Brazil. The cases reported in this study resulted from forensic analysis of six human skeletons found in northeastern Brazil between 2012 and 2014. Traces of tunnels and nests commonly produced by termites were found on several human bone surfaces as well as the specimens and characteristic signs of osteophagic activity. In four cases, the species were identified: Amitermes amifer Silvestri, 1901, Nasutitermes corniger (Motschulsky, 1855 (on two skeletons, and Microcerotermes indistinctus Mathews, 1977. In two other cases, the activity of termites on bone surfaces was evidenced by remains of nests and tunnels produced by these insects. At least in the samples of human remains available for this report, the number of termites collected was greater on bones found during autumn, the rainy season in the Northeast of Brazil. The human bones examined showed termites like insects with lots of strength at bone degradation, capable of continuing the process of decomposition of human remains even in completely skeletonized bodies.

    Full Text Available The Trad-MCN bioassay was used to investigate the genotoxicity on Tradescantia pallida var. purpurea plants exposed to variations in the environmental conditions in urban and rural sites in the metropolitan area of Porto Alegre, southern Brazil, over a one-year period. In spring 2009 and in summer, autumn and winter 2010, potted plants of T. pallida var. purpurea were exposed at two sites with different characteristics: the urban area of the municipality of Estância Velha, with leather and footwear industrial activity, and a Site of Special Environmental Interest in the rural area of the municipality of Novo Hamburgo. Other plants comprised the control group and were kept indoors. Frequencies of micronuclei (MCN were determined in early tetrads of pollen mother cells and expressed as MCN/100 tetrads. Climate data were also registered during the experiment. MCN frequencies in the urban area were significantly higher (up to 8.13 than those found in the rural area (up to 1.26 and in the control group (up to 1.10, which did not differ statistically from each other over the year. The higher MCN frequencies observed in the urban site can be attributed to air pollution, but also may have been influenced by microclimatic and daily thermal variation differences between sites. Higher temperatures recorded in spring and summer may have influenced MCN frequencies observed in the urban site. No clear relation was observed between rainfall and MCN frequencies. Similar and high relative humidity percentages were registered over the period of the study. Considering that the bioindicator plant presents an integrated response to abiotic factors such as pollutants and weather conditions, it can be used as an additional tool that can point to synergistic effects of environmental variables on organisms.

    The first confirmed case of Zika virus infection in the Americas was reported in Northeast Brazil in May 2015, although phylogenetic studies indicate virus introduction as early as 2013. Zika rapidly spread across Brazil and to more than 50 other countries and territories on the American continent. The Aedes aegypti mosquito is thought to be the principal vector responsible for the widespread transmission of the virus. However, sexual transmission has also been reported. The explosively emerging epidemic has had diverse impacts on population health, coinciding with cases of Guillain-Barré Syndrome and an unexpected epidemic of newborns with microcephaly and other neurological impairments. This led to Brazil declaring a national public health emergency in November 2015, followed by a similar decision by the World Health Organization three months later. While dengue virus serotypes took several decades to spread across Brazil, the Zika virus epidemic diffused within months, extending beyond the area of permanent dengue transmission, which is bound by a climatic barrier in the south and low population density areas in the north. This rapid spread was probably due to a combination of factors, including a massive susceptible population, climatic conditions conducive for the mosquito vector, alternative non-vector transmission, and a highly mobile population. The epidemic has since subsided, but many unanswered questions remain. In this article, we provide an overview of the discovery of Zika virus in Brazil, including its emergence and spread, epidemiological surveillance, vector and non-vector transmission routes, clinical complications, and socio-economic impacts. We discuss gaps in the knowledge and the challenges ahead to anticipate, prevent, and control emerging and re-emerging epidemics of arboviruses in Brazil and worldwide.

    Blood pressure (BP) increases with age in westernized societies, is higher in men, and is correlated with the body mass index (BMI). Traditional societies present more variable patterns of BP. In 1991, BP and anthropometric data from two "Caboclo" (rural populations of mixed ancestry) groups from Marajó Island, Brazil, were collected: The Paricatuba group, (N = 20;12 women), with a subsistence base of fishing, collection of palm fruits, and traditional gardening; and the Praia Grande group (N = 26; 14 women), where subsistence is based on mechanized agriculture. In Paricatuba, mean BP is 109/74 mmHg in men and 101/70 mmHg in women. There are no significant differences between BP of men and women, and systolic blood pressure (SBP) increases with age. Both SBP and diastolic blood pressure (DBP) are associated with weight, but only DBP is associated with the BMI, while SBP is associated with stature. In Praia Grande, mean BP is 120/76 mmHg in men and 118/70 mmHg in women, with no significant differences between the sexes. In Praia Grande, SBP is higher than in Paricatuba, and both SBP and DBP are associated with age. Compared with urban groups, both Caboclo samples have low BP. Still, differences in BP and body habitus between the two groups support a hypothesis that degree of westernization influences mean levels of BP in rural Amazonian populations. Further, the results also may be interpreted as suggesting that associations of sex, age, and BMI with BP, commonly reported in urban samples, are a byproduct of westernization rather than a result of genetic factors. © 1995 Wiley-Liss, Inc.

    AFONSO C. R. NOGUEIRA

    2001-06-01

    Full Text Available The waterfalls of the Presidente Figueiredo municipality represent a fascinating natural scenery of northeast state of Amazonas, northern Brazil. The falls, generally less than 10m high, are developed on siliciclastic rocks of the Nhamundá (Lower Silurian, and Manacapuru (Upper Silurian - Lower Devonian formations. Morphological and structural analyses of these features indicate that most of them originated through Quaternary neotectonics and are installed in NE-trending normal fault escarpments. Waterfalls also developed within pseudokarstic features, but are less frequent. The origin of the Presidente Figueiredo waterfalls probably goes back to the Neogene, when the region was submitted to laterization processes associated with a humid climate and a dense rainforest. These conditions favored the development of caves in quartzarenites of the Nhamundá Formation. During the Quaternary, the region was subjected to NE-trending normal faulting which displaced laterite layers, rivers and streams giving rise to waterfalls. These climatic and tectonic phenomena promoted intense relief dissection, as indicated by fault escarpment retreat and cave dismantlement, responsible for the present-day morphologic configuration.As cachoeiras da região de Presidente Figueiredo constituem um dos mais fascinantes cenários naturais do nordeste do Estado do Amazonas, norte do Brasil. As quedas, geralmente com menos de 10m de altura, são desenvolvidas em rochas siliciclásticas das formações Nhamundá (Siluriano inferior e Manacapuru (Siluriano superior-Devoniano inferior. Os estudos morfológico e estrutural dessas feições indicam que a maioria dessas quedas de água originaram-se por neotectônica quaternária e encontram-se instaladas em escarpas de falhas normais NE-SW. Ocorrem, ainda, com menor freqüência, cachoeiras evoluídas a partir de feições pseudocársticas. A origem das cachoeiras de Presidente Figueiredo provavelmente remonta ao Ne

    Full Text Available In rural India most of the surgical patients become impoverished due to surgical treatment pushing several families below poverty line. We describe the various methods that we tried to help these patients pay for the surgical procedures without becoming impoverished. Some of them were successful and many of them were not so successful. The large turnover and innovative methods helped the mission hospitals to serve the poor and the marginalized. Some of these methods might not be relevant in areas other than Northeast India while many could be used in other areas.

O objetivo da pesquisa foi a determinação da potência eólica média horária da direção predominante do vento em todas as estações selecionadas. Para tanto, identificou-se a direção predominante do vento de cada localidade e se estimaram os parâmetros da distribuição de Weibull, através dos quais se calculou a potência eólica média horária. Em função dos resultados apresentados neste trabalho, constatou-se que a direção predominante do vento no Nordeste do Brasil é de Leste, com flutuações para Sudeste e Nordeste. O ajuste do Método dos Momentos evidenciou-se melhor que o dos Mínimos Quadrados. Os Estados do Maranhão e Rio Grande do Norte apresentaram, respectivamente, o menor e maior potencial eólico. As estações de Alto Parnaíba, MA, e Acaraú, CE, apresentaram, mensalmente, a menor (0,022 W m-2 e a maior (138,302 W m-2 potência eólica, respectivamente.Hourly mean data of wind speed and direction, measured with a Fuess anemograph at 10 m height, were used in this study.

    Full Text Available The ability of the Artificial Neural Network (ANN and the Multiple Linear Regression (MLR in reproducing the area-average observed daily precipitation during the rainy season (Feb-Mar-Apr over the north of the Northeast of Brazil (NEB is examined. For the present climate of Dec-Jan-Feb from 1963 to 2003 period these statistical models are developed and validated using the observed daily precipitation and simulated from the historical outputs of 4 models of the fifth phase of the Coupled Model Intercomparison Project (CMIP5. The simulations from all the models during DJF and FMA seasons show an anomalous intensification of the ITCZ and southward displacement in comparison with the climatology. Correlations of 0.54, 0.66 and 0.66 are found between the simulated daily precipitation of the CCSM4, GFDL_ESM2M and MIROC_ESM models during DJF season and the observed values during FMA season. Only the CCSM4 model displays a slightly reasonable agreement with the observations. A comparison between the statistical downscaling using the nonlinear (ANN and linear model (MLR to identify the one most suitable for the analysis of daily precipitation was made. The ANN technique provides more ability to predict the present climate when compared to MLR technique. Based on this result, we examined the accuracy of the ANN model in project the changes for the future climate period from 2055 to 2095 over the same study region. For instance, a comparison between the daily precipitation changes projected indirectly from the ANN during Feb-Mar-Apr with those projected directly from the CMIP5 models forced by RCP 8.5 scenario is made. The results suggest that ANN model weights the CMIP5 projections according to the each model ability in simulating the present climate (and its variability. In others, the ANN model is a potentially promising approach to use as a complementary tool to improvement of the seasonal numerical simulations.

This virus has now been reported from three of the five Brazilian regions. Our study relates the findings concerning to the first isolate of this virus in Northern region of Brazil. A 15-month old female patient, from the rural zone of the municipality of Santana do Araguaia in southern Pará state was admitted at the hospital with acute, flaccid, asymmetric and ascending motor deficiency, located in the right lower limb. Stools samples from this child were inoculated in RD cells and was isolated an EV-71. We plan to sequence our strain and compare it to other isolates in Brazil. Differences at the molecular level can explain why EV-71 strains circulating in other continents, such as Asia, appear to be more virulent.

    2015-02-01

    Why do governments pursue obesity legislation? And is the case of Brazil unique compared with other nations when considering the politics of policy reform? Using a nested analytic approach to comparative research, I found that theoretical frameworks accounting for why nations implement obesity legislation were not supported with cross-national statistical evidence. I then turned to the case of Brazil's response to obesity at three levels of government, national, urban, and rural, to propose alternative hypotheses for why nations pursue obesity policy. The case of Brazil suggests that the reasons that governments respond are different at these three levels. International forces, historical institutions, and social health movements were factors that prompted national government responses. At the urban and rural government levels, receiving federal financial assistance and human resource support appeared to be more important. The case of Brazil suggests that the international and domestic politics of responding to obesity are highly complex and that national and subnational political actors have different perceptions and interests when pursuing obesity legislation.

    The employed energy in agricultural systems study, its flows, distribution and conversion constitute important instrumental for evaluation of the sustainability of these systems; mainly is tended in bill the current crisis in the energy sections. This procedure facilitates the determination of the processes, materials and equipment of larger energy consumption, indicating economy options. One of the main lacks that is noticed in the literature is the lack of information concerning the energy consumptions for constructions and facilities used in the several agricultural productive processes in Brazil. The work had as objective to accomplish an estimate of the involved energy in the construction of a rural building, in the Intensive System of Milk Production of EMBRAPA Gado de Leite, in Coronel Pacheco-MG Brazil. For the development of the work the energy coefficients lifted by the Fundacao Centro Tecnologico de Minas Gerais was used (CETEC). With the obtained results it could be observed that the energy index for construction area differentiated enough of those presented by the literature, being found values of 587,09 MJ.m-2, when the total area was linked and 622,23 MJ.m-2, when it was linked the useful hay storage static capacity area. The item of larger energy consumption for the analyzed type of rural building went to masonry wall (3,18 kJ.m-2), contributing with 46,77% of the total employed energy in the construction of the building. The covering structure, even considering included the structural elements, as pillars, it presented low energy consumption (50,35% of the total employed energy). The employed methodology confirmed its usefulness for the determination of materials and processes energy saving, in an ecological point of view. (author)

  16. Dengue virus 2 American-Asian genotype identified during the 2006/2007 outbreak in Piauí, Brazil reveals a Caribbean route of introduction and dissemination of dengue virus in Brazil.

    Leandra Barcelos Figueiredo

    Full Text Available Dengue virus (DENV is the most widespread arthropod-borne virus, and the number and severity of outbreaks has increased worldwide in recent decades. Dengue is caused by DENV-1, DENV- 2, DENV-3 and DENV-4 which are genetically distant. The species has been subdivided into genotypes based on phylogenetic studies. DENV-2, which was isolated from dengue fever patients during an outbreak in Piaui, Brazil in 2006/2007 was analyzed by sequencing the envelope (E gene. The results indicated a high similarity among the isolated viruses, as well as to other DENV-2 from Brazil, Central America and South America. A phylogenetic and phylogeographic analysis based on DENV-2E gene sequences revealed that these viruses are grouped together with viruses of the American-Asian genotype in two distinct lineages. Our results demonstrate the co-circulation of two American-Asian genotype lineages in northeast Brazil. Moreover, we reveal that DENV-2 lineage 2 was detected in Piauí before it disseminated to other Brazilian states and South American countries, indicating the existence of a new dissemination route that has not been previously described.

    Traditional health care practices are still being followed extensively in Manipur, North-East India. This is the major or the only medical facility available in some rural areas of Manipur. Cross cultural ethno-pharmacological survey was conducted to document traditional health care practices by Maiba-Maibi (male-female traditional health care practitioners of Manipur). All together 59 traditional practitioners belonging to 12 ethnic communities in nine districts of the Manipur state were interviewed. A predesigned questionnaire was used for interviews, which included queries for type of ailments treating, symptoms, bioresources used, method of preparation, dosage forms, formulation, unit doses. The entire interviews were done in the residence of respective Maiba-Maibi, their patient handing and preparation of medicinal formulations were documented in written and audio-visual format. The survey recorded traditional knowledge on 949 formulations used for 66 human ailments.

    A survey for seroprevalence of Chagas disease was held in a representative sample of Brazilian individuals up to 5 years of age in all the rural areas of Brazil, with the single exception of Rio de Janeiro State. Blood on filter paper was collected from 104,954 children and screened in a single laboratory with two serological tests: indirect immunofluorescence and enzyme linked immunoassay. All samples with positive or indetermined results, as well as 10% of all the negative samples were submitted to a quality control reference laboratory, which performed both tests a second time, as well as the western blot assay of TESA (Trypomastigote Excreted Secreted Antigen). All children with confirmed final positive result (n = 104, prevalence = 0.1%) had a follow-up visit and were submitted to a second blood collection, this time a whole blood sample. In addition, blood samples from the respective mothers and familiar members were collected. The infection was confirmed in only 32 (0.03%) of those children. From them, 20 (0.025%) had maternal positive results, suggesting congenital transmission; 11 (0.01%) had non-infected mothers, indicating a possible vectorial transmission; and in one whose mother had died the transmission mechanism could not be elucidated. In further 41 visited children the infection was confirmed only in their mothers, suggesting passive transference of maternal antibodies; in other 18, both child and mother were negative; and in 13 cases both were not localized. The 11 children that acquired the infection presumably through the vector were distributed mainly in the Northeast region of Brazil (States of Piauí, Ceará, Rio Grande do Norte, Paraíba and Alagoas), in addition to one case in Amazonas (North region) and another in Parana (South region). Remarkably, 60% of the 20 cases of probably congenital transmission were from a single State, Rio Grande do Sul, with the remaining cases distributed in other states. This is the first report demonstrating

    Full Text Available Abstract This paper deals with suicide in rural areas of Rio Grande do Sul, Brazil, considering the relation of this phenomenon with the advance of the capitalism in the countryside. This change has been creating new living and working styles and, besides, processes which lead to illness. Among these processes, suicide becomes a reality as a process of self-destruction and self-exclusion. These are sociopathologies of the development which are cre- ated in demonstrations of mental illness, depression and suicides, driven by a model of development imposed in the rural area through the economic incentive and, also, through all the economic speech carrying a project of hope. It is about the social and economic systems act- ing as generators of precariousness, human, familiar and psycho-philosophical costs, desocialization processes, self-generated alienation and self-cleaving, showing that it is increasingly necessary to think about the relation between the social and the individual in life and death processes. Resumo Este artigo trata da questão do suicídio no meio ru- ral no Rio Grande do Sul, Brasil, a partir da articulação deste fenômeno com o avanço capitalista no meio rural. Este último tem produzido novas formas de vida e tra- balho e, ademais, processos de adoecimento. Entre tais processos ganha corpo o suicídio enquanto processo de autodestruição, de autoexclusão. São as sociopatologias do desenvolvimento que se constituem em manifestações de doenças mentais, depressão e suicídios, alavancadas por um modelo de desenvolvimento imposto ao meio ru- ral através da incitação econômica e, ademais, por todo um discurso econômico portador de um projeto de espe- rança. É o sistema social e econômico agindo enquanto gerador da precariedade, de custos humanos, familiares, psicofisiológicos, de processos de dessocialização, de alienação autogerada, de clivagem de si apontando que se deve

    Full Text Available The impact of environmental changes is a major threat to livelihoods, especially for small farmers in semi-arid regions. Therefore, local communities undertake efforts to cope with these new environmental conditions and researchers try to understand the limits of possible adaptive strategies. Religiousness/spirituality are two important factors that can influence environmental awareness and adaptive responses to risks caused by natural phenomena. However, studies addressing the relationship between such factors are either scarce or based on anecdotal information. This article discusses the influence of religiousness/spirituality on the perception of environmental risks by farmers in a rural community in Brazil's northeast region, and their knowledge of adaptive strategies to deal with such concerns. Religiousness/spirituality can positively or negatively influence the perception of risk and knowledge of adaptive strategies when facing environmental uncertainty. We note that dimensions of religiousness/spirituality such as religious history, values/beliefs, commitment, and daily spiritual experiences influence wealth and the sharing of natural perceived risks, as well as adaptive strategies. Based on our results, we conclude that religiousness/spirituality dimensions exert both positive and negative effects on the perception of environmental risks and ways of coping with the impacts of rapid environmental changes.

    Sediment cores were taken from the mangroves of the Coreaú River estuary off the northeast coast of Brazil. They were analyzed for grain size, CaCO3, organic matter, and trace metal (Cd, Pb, Zn, Cu, Al, and Fe) contents. Mud texture was the predominant texture. Levels of trace metals in surface sediments indicated strong influence of anthropogenic processes, and diagenetic processes controlled the trace metal enrichment of core sediments of this estuary. The positive relationships between trace metals and Al and Fe indicate that Cu, Zn, Pb, and Cd concentrations are associated mainly with Al and Fe oxy-hydroxides and have natural sources.

    Dogs are important definite or reservoir hosts for zoonotic parasites. However, only few studies on the prevalence of intestinal parasites in urban areas in Brazil are available. We performed a comprehensive study on parasites of stray dogs in a Brazilian metropolitan area. We included 46 stray dogs caught in the urban areas of Fortaleza (northeast Brazil). After euthanization, dogs were autopsied. Ectoparasites were collected, and the intestinal content of dogs were examined for the presence of parasites. Faecal samples were collected and analysed using merthiolate iodine formaldehyde concentration method. A total of nine different parasite species were found, including five endoparasite (one protozoan, one cestode and three nematode species) and four ectoparasite species (two flea, one louse and one tick species). In the intestinal content, 3,162 specimens of four helminth species were found: Ancylostoma caninum (prevalence, 95.7%), Dipylidium caninum (45.7%), Toxocara canis (8.7%) and Trichuris vulpis (4.3%). A total of 394 ectoparasite specimens were identified, including Rhipicephalus sanguineus (prevalence, 100.0%), Heterodoxus spiniger (67.4%), Ctenocephalides canis (39.1%) and Ctenocephalides felis (17.4%). In the faeces, intestinal parasites were detected in 38 stray dogs (82.6%), including oocysts of Giardia sp. (2.2%) and eggs of the nematode A. caninum (82.6%). Neither eggs nor larval stages of D. caninum, T. canis or T. vulpis were detected in dog faeces. Sensitivity of faecal examination for A. caninum was 86.4% (95% confidence interval, 72.0-94.3) but zero percentage for the other intestinal helminth species. Our data show that stray dogs in northeast Brazil carry a multitude of zoonotic ecto- and endoparasites, posing a considerable risk for humans. With the exception of A. caninum, sensitivity of faecal examination was negligible.

    located in Fortaleza, capital city of the state of Ceará, in the Northeast of Brazil. A qualitative method, "The Patient's Pathway," was created and utilized. It blends ethnographic interviews, patient's narrative collected prospectively during the entire hospitalization - from admittance to discharge - and participant observation. The pathway of 13 key-informant patients was followed. Results reveal that our patients narrated 225 distinct hospitalization experiences. The majority (83.6% was interpreted by patients as "degrading" and "humiliating" their sense of personhood; only 16.4% were seen as "caring" for the patient, contributing to the recovery of their health. A progressive demoralization of the "suspect patient" is revealed, beginning with his/her reception by uniformed guards and confiscation of personal belongings. Hospitalization is characterized as abandonment, loneliness and imprisonment, due to the imposition of norms, rules and procedures which ignore patients' autonomy, subjectivity and personal conditions. Despite the oppressive hospital structure, patients manage to resist, drawing upon multiple strategies: personal traits, creative imagination, social solidarity and religious faith. Humanizing public hospitalization in the Northeast of Brazil requires including the patient's voice and experience while removing harmful stigmas.

    On 3 October 2005 a mesospheric front was observed over São João do Cariri (7.4° S, 36.5° W). This front propagated to the northeast and appeared in the airglow images on the west side of the observatory. By about 1.5 h later, it dissipated completely when the front crossed the local zenith. Ahead of the front, several ripple structures appeared during the dissipative process of the front. Using coincident temperature profile from the TIMED/SABER satellite and wind profiles from a meteor radar at São João do Cariri, the background of the atmosphere was investigated in detail. On the one hand, it was noted that a strong vertical wind shear in the propagation direction of the front produced by a semidiunal thermal tide was mainly responsible for the formation of duct (Doppler duct), in which the front propagated up to the zenith of the images. On the other hand, the evolution of the Richardson number as well as the appearance of ripples ahead of the main front suggested that a presence of instability in the airglow layer that did not allow the propagation of the front to the other side of the local zenith.

  8. Study for uranium advantage as byproduct of the phosphorite from Brazilian Northeast

    1974-01-01

    The distribution and recovery of uranium contained in marine phosphates from Northeast Brazil were investigated by treating these ores with hydrochloric acid. The average content of uranium in the phosphorite was found to be about 0.03%. The leaching of phosphate from the ore and the amount of solubilized uranium supplied the basic information for the uranium recovery. The solutions, obtained in laboratory, leaching the phosphorite with hydrochloric acid contained 40.70 mg:U/l. An analytical method to control the uranium solubilization was outlined. A liquid-liquid extraction of uranium from these leaching solutions was performed using mixture of 3.3% di-(2-ethyl-hexyl)-phosphoric acid and 2.2% TBP in kerosene. After extraction the phosphoric acid free from uranium is sent to the calcium hydrogeno-phosphate production. The uranium is stripped from the organic phase by alkaline treatment and then precipitated as diuranate. (Author) [pt

    Cryptococcus neoformans and Cryptococcus gattii are responsible globally for almost one million cryptococcosis cases yearly, mostly in immunocompromised patients, such as those living with HIV. Infections due to C. gattii have mainly been described in tropical and subtropical regions, but its adaptation to temperate regions was crucial in the species evolution and highlighted the importance of this pathogenic yeast in the context of disease. Cryptococcus gattii molecular type VGII has come to the forefront in connection with an on-going emergence in the Pacific North West of North America. Taking into account that previous work pointed towards South America as an origin of this species, the present work aimed to assess the genetic diversity within the Brazilian C. gattii VGII population in order to gain new insights into its origin and global dispersal from the South American continent using the ISHAM consensus MLST typing scheme. Our results corroborate the finding that the Brazilian C. gattii VGII population is highly diverse. The diversity is likely due to recombination generated from sexual reproduction, as evidenced by the presence of both mating types in clinical and environmental samples. The data presented herein strongly supports the emergence of highly virulent strains from ancestors in the Northern regions of Brazil, Amazonia and the Northeast. Numerous genotypes represent a link between Brazil and other parts of the world reinforcing South America as the most likely origin of the C. gattii VGII subtypes and their subsequent global spread, including their dispersal into North America, where they caused a major emergence.

    The WHO recommends the use of some anthropometric parameters as a screening resource for individuals under cardiometabolic risk. However, in the validation of these indicators, Brazilian women were not included. These women have different anthropometric profile compared to women who integrated the samples of the validation studies. We aimed to verify the accuracy of anthropometric indicators as a resource for the screening of women with hypertension. A cross-sectional study, with a probability sample of 3143 women (20-49 years) from the state of Alagoas (northeast of Brazil), was carried out. Hypertension was identified by systolic blood pressure (SBP) ≥140 mm Hg and/or diastolic BP ≥90 mm Hg and/or regular use of antihypertensive drugs. The anthropometric indicators analyzed were BMI, waist circumference, waist-to-hip ratio, waist-to-height ratio (WHtR), body fat percentage, and conicity index. The accuracy definition of the indicators and the identification of best cut-off points were carried out on the basis of ROC curve analysis and Youden index, respectively. The prevalence of hypertension was 21.8%. All indicators used in hypertension identification had area under the ROC curve (AUC) >0.5. The WHtR with cut-off point of 0.54 was the best performance indicator (AUC = 0.72; P hypertension. In the absence of specific studies and considering the largest ethnic proximity and environmental/epidemiological similarity, the findings now obtained can be extended to women of other Brazilian states, especially those in the Northeastern region.

This analysis found a rapid decrease in the prevalence of childhood malnutrition and an even more rapid increase in adult overweight/obesity. Correction of the height deficit was 72% in urban children and 54.4% in rural children. Obesity rates doubled or tripled in adult men and women at the extremes of the time series analyzed. Excluding the rural Northeast, malnutrition prevalence in adult women dropped to acceptable rates (about 5% starting in 1989. Inversely, anemia continued to display a high prevalence, and there is indication of an epidemic trend. The evolution of nutritional status in the Brazilian population according to macro-regions and social distribution is reported. The likely factors for the observed changes are analyzed.

  12. Agricultural and forestry residues for decentralized energy generation in Brazil

    Energy Technology Data Exchange (ETDEWEB)

    2011-10-11

    Regular electricity access is a key element for the economic development and social welfare of rural areas. Decentralized energy generation has the advantage of using local resources, increasing employment and reducing transmission and distribution losses. Brazil is a tropical country, endowed with vast arable land, plentiful precipitation levels, and a large supply of human labour. Furthermore, it has strong regional distinctions with geographical, cultural and economical differences. Forestry and agriculture, important activities in the Brazilian economy, are dependent on local people and are deeply connected to traditions, nature and culture. Furthermore, these activities generate a significant amount of residues that could be used in conversion technologies for biomass, based on type, availability and market demand. When biomass were used to generate energy locally, community members could have business opportunities, improving local economy and life quality of individuals while diversifying the Brazilian energy matrix, which is mostly based on hydropower. Alternatives for implementing small-scale decentralized biomass schemes are dependent on the screening of the existing biomass supply chains, the implementation of adapted technologies for local conditions and the exploration of local resources. The present research carried out a detailed field work in order to evaluate the potential of Brazilian biomass in different regions. The author identified crucial needs, usual constraints and possible challenges of rural electrification and economic development in Brazil. Several case studies and social groups were investigated in the Federal States of Minas Gerais, Sao Paulo and Para to identify different resource management strategies, which biomass technology was applied and the needs of the local population. It was concluded that the compaction of biomass to generate solid biofuels with uniform properties could be a cost-effective alternative for communities

    Full Text Available The rat lungworm Angiostrongylus cantonensis is a worldwide-distributed zoonotic nematode that can cause human eosinophilic meningoencephalitis. Here, for the first time, we report the isolation of A. cantonensis from Achatina fulica from two Brazilian states: Rio de Janeiro (specifically the municipalities of Barra do Piraí, situated at the Paraiba River Valley region and São Gonçalo, situated at the edge of Guanabara Bay and Santa Catarina (in municipality of Joinville. The lungworms were identified by comparing morphological and morphometrical data obtained from adult worms to values obtained from experimental infections of A. cantonensis from Pernambuco, Brazil, and Akita, Japan. Only a few minor morphological differences that were determined to represent intra-specific variation were observed. This report of A. cantonensis in South and Southeast Brazil, together with the recent report of the zoonosis and parasite-infected molluscs in Northeast Brazil, provide evidence of the wide distribution of A. cantonensis in the country. The need for efforts to better understand the role of A. fulica in the transmission of meningoencephalitis in Brazil and the surveillance of molluscs and rodents, particularly in ports, is emphasized.

    Worldwide, half the population lives in rural or remote areas; however, less than 25% of doctors work in such regions. Despite the continental dimensions of Brazil and its enormous cultural diversity, only some medical schools in this country offer students the opportunity to acquire work experience focused on medicine in rural or remote areas. The objective of the present study was to develop a framework of competencies for a longitudinal medical training program in rural medicine as an integrated part of medical training in Brazil. Two rounds of a modified version of the Delphi technique were conducted. Initially, a structured questionnaire was elaborated, based on a literature review. This questionnaire was submitted to the opinion of 20 panelists affiliated with the Rural Medicine Working Party of the Brazilian Society of Family and Community Medicine. The panelists were asked to evaluate the relevance of the competencies using a five-point Likert-type scale. In this study, the consensus criterion for a competency to be included in the framework was it being deemed 'very important' or 'indispensable' by a simple majority of the participants, while the criterion for excluding a competency was that a simple majority of the panel members considered that it 'should not be included' or was 'of little importance'. When a consensus was not reached regarding a given competency, it was submitted to a second round to enable the panelists to re-evaluate the now dichotomized questions. Compliance in responding to the questionnaire was better among the panelists predominantly involved in teaching activities (85%; n=12) compared to those working principally in patient care (45%; n=8). The questionnaire consisted of 26 core competencies and 165 secondary competencies. After evaluation by the specialists, all the 26 core competencies were classified as relevant, with none being excluded and only eight secondary competencies failing to achieve a consensus. No new competencies

    Several arboviruses, including dengue virus (DENV), Zika virus (ZIKV) and chikungunya virus (CHIKV), transmitted by Aedes mosquitoes, circulate in northeast Brazil. Diseases caused by these viruses are of great public health relevance, however, their epidemiological features in areas where the three viruses co-circulate are scarce. Here, we present analyses of molecular and serological diagnostics in a prospective study of acute febrile patients recruited from May 2015 to May 2016 in Recife, Brazil. Two hundred sixty-three acute febrile patients with symptoms suggestive of an arboviral disease who attended an urgent heath care clinic in the Recife Metropolitan Region in northeast Brazil were enrolled. Acute and convalescent blood samples were collected and tested using molecular and serological assays for infection with DENV, ZIKV and CHIKV. Quantitative real-time reverse-transcriptase polymerase chain reactions (qRTPCR) performed on acute phase sera detected no patients positive for DENV, but 26 (9.9%) positive for ZIKV and 132 (50.2%) positive for CHIKV. There were a few suspected and only one confirmed dengue case. Specific serological assays for ZIKV and CHIKV confirmed the qRTPCR data. Analyses of DENV IgM and IgG ELISAs in the context of qRTPCR results suggested high levels of cross reactive antibodies in ZIKV-positive samples. Results from neutralization assays highly corroborated those from qRTPCR and ZIKV ELISA, indicating very few positive DENV cases. ZIKV infections were temporally clustered in the first months of the study and started to decrease concomitantly with an increase in CHIKV infections in August 2015. The proportion of CHIKV infections increased significantly in September 2015 and remained high until the end of the study period, with an average of 84.7% of recruited patients being diagnosed from August 2015 to May 2016. ZIKV infections exhibited a female bias and the cases were spread over the study site, while CHIKV cases had a male bias and

    A sequence of Brasiliano-age granitoid types is exposed in a small area near the cities of Umarizal and Caraúbas in Rio Grande do Norte State, Northeast Brazil. Porphyritic K-alkali-calcic monzogranite is an important facies of the oldest Caraúbas intrusion (RbSr whole rock isochron age of ca. 630 Ma), which suffered solid-state deformation due to movements on a major NE-trending shear zone. The intrusion of the Prado and part of the Quixaba bodies was probably controlled by the shear zone. These two bodies include mafic/intermediate rocks, some of which contain two pyroxenes, and have hybrid, partly alkaline and partly shoshonitic geochemical characteristics. Rock types and ages are similar to those of some Pan-African occurrences in southwestern Nigeria. The Tourão body, intruded at ca. 590 Ma, presents preferred mineral orientations which are probably largely magmatic, since little evidence is found for widespread solid-state deformation. On the other hand, its intrusion may have been facilitated by the presence of the shear-zone faults. The rocks form a monomodal felsic K-alkali-calcic suite. With the exception of the Quixaba body, all these earlier granitoids are magmatic epidote- and magnetite-bearing porphyritic monzogranites with trace element geochemical characteristics of modern syn-collisional granites. The latest intrusion at ca. 545 Ma is mainly represented by potassic quartz syenites and related rocks, some of which contain fayalite or ferrohypersthene. These rocks possess neither well developed mineral orientations of magmatic origin nor signs of solid-state deformation. They are mineralogically similar to, but younger than some of the "bauchites" of central Nigeria. Geochemical signatures are comparable with those of modern within-plate granites. All granitoids present high ( 87Sr/ 86Sr)i ratios which range from 0.708 to 0.712, and increase with decreasing age. Such ratios are compatible with important or dominant crustal contributions.

    Surface O{sub 3} was monitored continuously during Aug. 12, 2010 to Jul. 21, 2011 at a high elevation site (3200 m above sea level) in Qinghai Lake area (36°58′37″N, 99°53′56″E) in Northeast Tibetan Plateau, China. Daily average O{sub 3} ranged from 21.8 ppbv to 65.3 ppbv with an annual average of 41.0 ppbv. Seasonal average of O{sub 3} followed a decreasing order of summer > autumn > spring > winter. Diurnal variations of O{sub 3} showed low concentrations during daytime and high concentrations during late night and early morning. An intensive campaign was also conducted during Aug. 13–31, 2010 to investigate correlations between meteorological or chemical conditions and O{sub 3}. It was found that O{sub 3} was poorly correlated with solar radiation due to the insufficient NO{sub x} in the ambient air, thus limiting O{sub 3} formation under strong solar radiation. In contrast, high O{sub 3} levels always coincided with strong winds, suggesting that stratospheric O{sub 3} and long range transport might be the main sources of O{sub 3} in this rural area. Back-trajectory analysis supported this hypothesis and further indicated the transport of air masses from northwest, northeast and southeast directions. - Highlights: • Surface O{sub 3} was measured in Qinghai Lake area in Northeast Tibetan Plateau, China. • The O{sub 3} chemical formation was under a strong NOx-limited in Qinghai Lake areas. • Stratospheric O{sub 3} and transport might be the main sources of O{sub 3} in this area.

    SUMMARY Chagas disease and the leishmaniases are endemic zoonoses of great importance to public health in the state of Piauí, Brazil. The domestic dog (Canis familiaris) is a major reservoir, host of Trypanosoma cruzi and Leishmania spp. in both urban and rural areas, playing an important role in the transmission of these parasites. The present study evaluated the prevalence of both infectious diseases in dogs of a rural area in the municipality of São João do Piauí, Piauí State. One hundred twenty-nine blood samples were collected for serological assessment: for the leishmaniases, 49 (38%) animals tested positive by the Dual-Path Platform technology (DPP), nine (6%) by the Enzyme-linked Immunosorbent Assay (ELISA), and 19 (14.7%) by the Indirect Fluorescent Antibody test (IFA); while for American Trypanosomiasis, 36 (28%) dogs were reagent by ELISA and 21 by IFA. Of the 129 dogs sampled, 76 were submitted to xenodiagnosis, bone marrow aspiration and skin biopsy to perform parasitological tests whose results showed only one (2.3%) positive skin sample for Trypanosoma caninum and one positive xenodiagnosis for T. cruzi, both results confirmed by molecular assays. Three hundred triatomines of the species Triatoma brasiliensis and 552 phlebotomines - 509 (97%) of the species Lutzomyia longipalpis, were also captured. PMID:27828620

    This study characterized the botanical knowledge of artisanal fishers of the Lami community, Porto Alegre, southern Brazil based on answers to the following question: Is the local botanical knowledge of the artisanal fishers of the rural-urban district of Lami still active, even since the district's insertion into the metropolitan region of Porto Alegre? This region, which contains a mosaic of urban and rural areas, hosts the Lami Biological Reserve (LBR) and a community of 13 artisanal fisher families. Semi-structured interviews were conducted with 15 fishers, complemented by participatory observation techniques and free-lists; in these interviews, the species of plants used by the community and their indicated uses were identified. A total of 111 species belonging to 50 families were identified. No significant differences between the diversities of native and exotic species were found. Seven use categories were reported: medicinal (49%), human food (23.2%), fishing (12.3%), condiments (8%), firewood (5%), mystical purposes (1.45%), and animal food (0.72%). The medicinal species with the highest level of agreement regarding their main uses (AMUs) were Aloe arborescens Mill., Plectranthus barbatus Andrews, Dodonaea viscosa Jacq., Plectranthus ornatus Codd, Eugenia uniflora L., and Foeniculum vulgare Mill. For illness and diseases, most plants were used for problems with the digestive system (20 species), followed by the respiratory system (16 species). This community possesses a wide botanical knowledge, especially of medicinal plants, comparable to observations made in other studies with fishing communities in coastal areas of the Atlantic Forest of Brazil. Ethnobotanical studies in rural-urban areas contribute to preserving local knowledge and provide information that aids in conserving the remaining ecosystems in the region.

    Full Text Available BACKGROUND: In recent decades, early diagnosis of childhood cancer has taken an important place on the international agenda. The authors of this study evaluated a group of medical students in Recife, Brazil, regarding knowledge and practices related to early diagnosis of common childhood cancers. METHODS: Cross-sectional study with a sample of 82 medical students, from a total of 86 eligible subjects. Data were collected using self-completed questionnaires. Subgroups were defined according to knowledge of the theme and students' perceptions of their own skills and interest in learning. RESULTS: 74.4% of the sample demonstrated a minimum level of knowledge. The group without minimum knowledge or self-perceived competence to identify suspected cases (23.3% was in the worst position to perform early diagnosis. All subjects expressed interest in learning more about this topic. CONCLUSIONS: Despite acceptable levels of knowledge among these medical students, the definition of central aspects of the teaching and learning processes would be useful for training physicians with the skills for diagnosing and treating pediatric cancers

    Fishermen's knowledge is a source of indispensable information in decision-making processes related to efforts to stimulate the management and conservation of fishing resources, especially in developing countries. This study analyzed the knowledge of fishermen from three municipal areas of Bahia in northeast Brazil regarding the behavior repertoire of sharks and the possible influence that these perceptions may have on the inclination to preserve these animals. This is a pioneering study on the ethnobiological aspects of elasmobranchs in Brazil. Open, semi-structured interviews with shark fishing specialists were conducted between September 2011 and October 2012. The interviews addressed the fishermen's profile, fishing techniques and knowledge about sharks, focusing on the behaviours exhibited by sharks. The data were analysed with quantitative approach and conducted with the use of descriptive statistical techniques. Sixty-five fishermen were interviewed. They descend from the rafting subculture of Brazil's northeast, which has historically been disregarded by public policies addressing the management and conservation of fishing resources. The fishing fleet involved in shark fishing includes rafts, fishing boats and lobster boats equipped with fishing lines, gillnets, longlines and "esperas". The informers classified sharks' behaviour repertoire into 19 ethological categories, related especially to feeding, reproduction, and social and migratory behaviours. Because they identify sharks as predators, the detailed recognition of the behaviours exhibited is crucial both for an efficient catch and to avoid accidents. Therefore, this knowledge is doubly adaptive as it contributes to safer, more lucrative fishing. A feeling of respect for sharks predominates, since informers recognize the ecological role of these animals in marine ecosystems, attributing them the status of leader (or "the man") in the sea. This work demonstrates the complexity and robustness of

    To quantify the trend of ischaemic heart disease (IHD) deaths in Brazil during the last decade (2000-2010) for various population characteristics and to forecast the upcoming mortality trends across regions in Brazil until the year 2015. Nationwide comparative observational study. The population studied encompassed all adult residents (≥ 20 years) living in five Brazilian regions between 2000 and 2010. Demographic, economic and mortality data were obtained from Brazilian National Mortality Data System and National Applied Economics Research Institute. Subnotified deaths were redistributed proportionally to IHD deaths. Age-standardised mortality rates (ASMRs) per 100 000 inhabitants, by sex and region, were calculated employing a standard Brazilian population and constructing multivariate regression models to quantify and to project temporal trends. Absolute numbers of death due to IHD and region-specific death rates in Brazil by age and sex. During the study period, 627 786 men and 452 690 women died due to IHD in Brazil. ASMR trends across all regions for men and women converged, driven by a declining trend in the South and Southeast and an opposite incline in the North and Northeast (p < 0.05). Future projections demonstrated potential widening of the observed North-South gap in coming years. The IHD death trend in Brazil has changed from a decline to a stagnant state. However, a significant discrepancy in mortality trends exists between the northern and southern regions, which is likely to widen further. Reappraisal of the public health policies tailored to populations with diverse socioeconomic structures is urgently required.

The number of speciesrecorded is 304, with Drosophila being the genus with the greatest number of species, followed by Zygothrica,Hirtodrosophila and Diathoneura, which belong to the Drosophilinae subfamily. Drosophila was shown to be the mostinvestigated taxon in the family, with the best resolved species distribution. The low number of records of species fromother genera indicates the paucity of studies specifically designed to investigate these species. Records of species forsome regions of the country like the north and northeast, as well as for some biomes like Caatinga, Pantanal and thePampas, are likewise rare. Apart from the banana bait, different collection methods may be necessary, like thecollection at other oviposition resources, the use of baits other than fermenting fruit, and the adoption of samplingapproaches that do not use baits.

    The alkali-aggregate reaction (AAR) in concrete structures is a problem that has concerned engineers and researchers for decades. This reaction occurs when silicates in the aggregates react with the alkalis, forming an expanded gel that can cause cracks in the concrete and reduce its lifespan. The aim of this study was to characterize three coarse granitic aggregates employed in concrete production in northeastern Brazil, correlating petrographic analysis with the kinetics of silica dissolution and the evolution of expansions in mortar bars, assisted by SEM/EDS, XRD, and EDX. The presence of grains showing recrystallization into individual microcrystalline quartz subgrains was associated with faster dissolution of silica and greater expansion in mortar bars. Aggregates showing substantial deformation, such as stretched grains of quartz with strong undulatory extinction, experienced slower dissolution, with reaction and expansion occurring over longer periods that could not be detected using accelerated tests with mortar bars.

    Northeastern Brazil is a region with a large number of natural radioactive occurrences. Monitoring studies carried out over the last 30 years have identified a hundred anomalous points, especially in the State of Paraiba, more specifically the region of Serido Ocidental Paraibano, geologically characterized by the presence of rocky outcrops with radioactive materials associated with granites and pegmatites. Regions with differentiated levels of natural radioactivity and, consequently, greater radioecological relevance, have been the constant object of radiometric and dosimetric studies. Considering their relevance, the present study aimed to evaluate the levels of natural radioactivity in rocks located in the Riacho da Serra and Serra dos Porcos, previously unmonitored, located in the municipalities of Sao Jose do Sabugi and Santa Luzia, in Paraiba, Northeast of Brazil. The radiometric evaluation was performed by measuring the specific activities of U-238, Th-232 and K-40 in rock samples using a high resolution gamma spectrometry system. The mean specific activities of U-238, Th-232 and K-40 were: 2562.30 ± 672.22; 180.68 ± 672.22 and 1374.13 ± 36.90 Bq/kg, respectively. The monitored radionuclides presented high values of specific activity, being 1.6; 4.1 and 71.2 times higher than the mean values for the earth's crust. (author)

  10. Plantation forestry in Brazil: the potential impacts of climatic change

    International Nuclear Information System (INIS)

    Fearnside, P.M.

    Most climatic changes predicted to occur in Brazil would replace yields of silvicultural plantations, mainly through increased frequency and severity of droughts brought on by global warming and by reduction of water vapor sources in Amazonia caused by deforestation. Some additional negative effects could result from changes in temperature, and positive effects could result from CO 2 enrichment. The net effects would be negative, forcing the country to expand plantations onto less-productive land, requiring increased plantation area (and consequent economic losses) out of proportion to the climatic change itself. These impacts would affect carbon sequestration and storage consequences of any plans for subsidizing silviculture as a global warming mitigation option. Climate change can be expected to increase the area of plantations needed to supply projected internal demand for and exports of end products from Brazil. June-July-August (dry season) precipitation reductions indicated by simulations reported by the Intergovernmental Panel on Climate Change (IPCC) correspond to rainfall declines in this critical season of approximately 34% in Amazonia, 39% in Southern Brazil and 61% in the Northeast. As an example, if rainfall in Brazilian plantation areas (most of which are now in Southern Brazil) were to decline by 50%, the area needed in 2050 would expand by an estimated 38% over the constant climate case, bringing the total area to 4.5 times the 1991 area. These large areas of additional plantations imply substantial social and environmental impacts. Further addition of plantation area as a global warming response option would augment these impacts, indicating the need for caution in evaluating carbon sequestration proposals. (author)

    The main objective of this study was to evaluate the incidence of tooth decay in adolescents, associated with socioeconomic status, access to services, and self-perceived oral health. This was a longitudinal study using an epidemiological survey of dental caries and a structured questionnaire with a sample of 688 adolescents residing in Sobral, Ceará State, Brazil. Incidence increased progressively with age, from 1.60 at 12 years of age to 2.28 at 15, with a mean incidence of 1.86 decayed teeth per adolescent. Among the study variables, tooth pain in the previous six months [RR = 1.46 (1.22-1.76)], school lunch [RR = 1.45 (1.21-1.74)], frequency of dental appointments [RR = 1.48 (1.33-1.79)], and access to the Health Service [RR = 1.21 (1.01-1.45)], adjusted by perceived need for treatment, were associated with high caries incidence. It is essential for health professionals and health system managers to formulate public policies that are not limited merely to clinical and preventive aspects, encouraging the population to struggle for better living conditions and allowing equitable access to services and developing collective management of health actions.

    Rural planning is perceived as a spatial planning centered on the human settlements and there are many activities for rural reconstruction and researches conducted from the perspective of active intervention, with fewer studies regarding the village as the main body for the establishment of self-built system. And the other-organization built by the rural areas is strongly oriented. In Asian countries like China, South Korea and Japan, there are farming traditions, in which the familial and small-scale farmland holding and agricultural production mode are deep-rooted. Traditional agriculture and rural areas are not fundamentally changed by industrialization and modernization process. And the small-scale peasant in the East is marked by the decentralized possession of farmland and management in the rural areas and a large number of farmers to be remained. But the rural population keeps decreasing. After analyzing the status quo of human settlements in China, Korea and Japan, the paper makes an analysis from the different ways of thinking and professional perspective and focuses on putting forward the solutions to the problems on macro level, with the feasibility of the practical significance and the landing researches still staying in the testing stage. In the context of increasingly missing regional and contextual features, the launching and researches of “co-constructed community” as the folk protection way to emerging rural heritage are just started, and the researches on rural construction in Northeast China from the perspective of catalyst are absent. The contact agent with the catalytic action mechanism of seeing big things through small ones fits the rural areas marked by vast territory and diversified aspect, which is applicable to the bottom-up operation mechanism autonomously built by the villagers.

    Motor-vehicle crashes are a leading cause of death in the United States. Compared with urban residents, rural residents are at an increased risk for death from crashes and are less likely to wear seat belts. These differences have not been well described by levels of rurality. 2014. Data from the Fatality Analysis Reporting System (FARS) and the Behavioral Risk Factor Surveillance System (BRFSS) were used to identify passenger-vehicle-occupant deaths from motor-vehicle crashes and estimate the prevalence of seat belt use. FARS, a census of U.S. motor-vehicle crashes involving one or more deaths, was used to identify passenger-vehicle-occupant deaths among adults aged ≥18 years. Passenger-vehicle occupants were defined as persons driving or riding in passenger cars, light trucks, vans, or sport utility vehicles. Death rates per 100,000 population, age-adjusted to the 2000 U.S. standard population and the proportion of occupants who were unrestrained at the time of the fatal crash, were calculated. BRFSS, an annual, state-based, random-digit-dialed telephone survey of the noninstitutionalized U.S. civilian population aged ≥18 years, was used to estimate prevalence of seat belt use. FARS and BRFSS data were analyzed by a six-level rural-urban designation, based on the U.S. Department of Agriculture 2013 rural-urban continuum codes, and stratified by census region and type of state seat belt enforcement law (primary or secondary). Within each census region, age-adjusted passenger-vehicle-occupant death rates per 100,000 population increased with increasing rurality, from the most urban to the most rural counties: South, 6.8 to 29.2; Midwest, 5.3 to 25.8; West, 3.9 to 40.0; and Northeast, 3.5 to 10.8. (For the Northeast, data for the most rural counties were not reported because of suppression criteria; comparison is for the most urban to the second-most rural counties.) Similarly, the proportion of occupants who were unrestrained at the time of the fatal crash

    In recent years, a new pattern of schistosomiasis transmission has been described which is related to recreational activities associated with rural or ecological tourism and migratory flows and accompanying changes in social dynamics in Brazil. The objective of this report is to describe two schistosomiasis outbreaks that occurred during the practice of rural tourism in Minas Gerais, Brazil, and review this pattern of transmission within the wider context of schistosomiasis control. The first outbreak was characterized by its high infection rate, showing that 59 % of the exposed eco-tourists became positive for infection with Schistosoma mansoni . In addition, all three disease transmitting species of intermediate host snails were found in the area. In the second outbreak, all members of one tourist family were infected and reported contact with water in a well-known tourist area. The malacological survey in the region revealed an infection rate with S. mansoni of 8.3 % among the collected snails. Infection of urban dwellers that report contact with contaminated water associated with ecotourism represents a new pattern of disease transmission and dissemination. The infection with the disease at these occasions finds its expression in outbreaks of acute schistosomiasis among internal tourists to rural areas. Therefore, epidemiological surveillance in endemic areas should be aware of this schistosomiasis transmission pattern, and a multidisciplinary approach, most of all sanitation and health education measures, is required in order increase the efficiency of control strategies.

    The dermatophytes, keratinophilic fungi, represent important microorganisms of the soil microbiota, where there are cosmopolitan species and others with restricted geographic distribution. The aim of this study was to broaden the knowledge about the presence of dermatophytes in soils of urban (empty lots, schools, slums, squares, beaches and homes) and rural areas and about the evolution of their prevalence in soils of varying pH in cities of the four mesoregions of Paraiba State, Brazil. Soil samples were collected from 31 cities of Paraiba State. Of 212 samples, 62% showed fungal growth, particularly those from the Mata Paraibana mesoregion (43.5%), which has a tropical climate, hot and humid. Soil pH varied from 4.65 to 9.06, with 71% of the growth of dermatophytes occurring at alkaline pH (7.02 - 9.06) (ρ = 0.000). Of 131 strains isolated, 57.3% were geophilic species, particularly Trichophyton terrestre (31.3%) and Mycrosporum gypseum (21.4%). M. nanum and T. ajelloi were isolated for the first time in Paraiba State. The zoophilic species identified were T. mentagrophytes var. mentagrophytes (31.3 %) and T. verrucosum (7.6 %), and T. tonsurans was isolated as an anthropophilic species. The soils of urban areas including empty lots, schools, slums and squares of cities in the mesoregions of Paraiba State were found to be the most suitable reservoirs for almost all dermatophytes; their growth may have been influenced by environmental factors, soils with residues of human and/or animal keratin and alkaline pH.

    For Brazil, a country frequented by droughts and whose rural inhabitants largely depend on groundwater, reliance on isotope for its monitoring, though accurate, is expensive and limited in spatial coverage. We exploit total water storage (TWS) derived from Gravity Recovery and Climate Experiment (GRACE) satellites to analyse spatial-temporal groundwater changes in relation to geological characteristics. Large-scale groundwater changes are estimated using GRACE-derived TWS and altimetry observations in addition to GLDAS and WGHM model outputs. Additionally, TRMM precipitation data are used to infer impacts of climate variability on groundwater fluctuations. The results indicate that climate variability mainly controls groundwater change trends while geological properties control change rates, spatial distribution, and storage capacity. Granular rocks in the Amazon and Guarani aquifers are found to influence larger storage capability, higher permeability (>10 -4 m/s) and faster response to rainfall (1 to 3months' lag) compared to fractured rocks (permeability 3months) found only in Bambui aquifer. Groundwater in the Amazon region is found to rely not only on precipitation but also on inflow from other regions. Areas beyond the northern and southern Amazon basin depict a 'dam-like' pattern, with high inflow and slow outflow rates (recharge slope > 0.75, discharge slope 30cm). Amazon's groundwater declined between 2002 and 2008 due to below normal precipitation (wet seasons lasted for about 36 to 47% of the time). The Guarani aquifer and adjacent coastline areas rank second in terms of storage capacity, while the northeast and southeast coastal regions indicate the smallest storage capacity due to lack of rainfall (annual average is rainfall <10cm).

    We studied the distribution of deaths from ill-defined causes that occurred in Brazil during 2003, from which was identified the proportion of unattended deaths. Data were obtained from the Mortality Information System, coordinated by the Ministry of Health. Causes of death included in "Chapter XVIII - Symptoms, signs and abnormal clinical and laboratory findings, not classified elsewhere" of the International Statistical Classification of Diseases and Related Health Problems, tenth revision, were considered ill-defined, among which the category R98 identified "unattended deaths". In Brazil during 2003 the underlying causes of 13.3% of deaths were included in the Chapter of ill-defined causes, and the highest proportions of these deaths occurred in the Northeast and North Regions. Considering the total deaths from ill-defined causes, 53 % correspond to unattended deaths. This proportion increased to over 70% in the states of Maranhão, Piauí, Rio Grande do Norte, Pernambuco, Bahia, Paraíba and Alagoas. Due to the decentralized structure of data collection in the country, we believe that the municipalities bear the major responsibility, followed by the states, for upgrading the quality of mortality statistics.

O presente estudo apresenta informações epidemiológicas inéditas para o município, oferecendo subsídios para o planejamento estratégico e normativo das ações de saúde bucal no sistema local de saúde.The present study is an attempt to characterize dental needs of the rural population in Itapetininga, São Paulo State, Brazil. One single dentist examined 291 children ages 5 and 12 years in rural schools, adopting WHO criteria for oral health surveys. Parents reported their children's socioeconomic characteristics and habits. Non-primary data gathered by the Brazilian health authority supplied information regarding the schoolchildren in the urban area of the town. Caries indices ranked as follows: dmft = 2.63 (5-year-old children and DMFT = 2.45 (12-year-old children. The decayed component comprised 85.6% of the dmft and 34.2% of the DMFT, indicating limited utilization of dental treatment by children with decayed deciduous teeth. Caries prevalence was higher in rural schoolchildren than in their urban counterparts. Analysis of the results aims to improve planning of dental care.

    Full Text Available Revisão da literatura sobre o nanismo nutricional no Brasil. Os principais tópicos abordados foram: definição do problema, a utilização da medida da altura em escolares como método de excelência para avaliar o estado de saúde e nutrição das populações, as principais causas e conseqüências apontadas na literatura e sua magnitude no país. De acordo com a literatura a prevalência do nanismo nutricional varia entre as diversas regiões brasileiras, com nítida desvantagem para as regiões Norte e Nordeste. Sua origem tem sido atribuída especialmente a condições ambientais desfavoráveis. Há indicações de que o atraso da capacidade intelectual e menor capacidade física para o trabalho estão associados ao problema.Literature review on stunting in Brazil. The following topics have been analyzed: problem's definition, the use of schoolchildren's height as the best method to evaluate population health and nutritional status, the main causes and consequences demonstrated in the literature and, at last, the scope of this problem in Brazil. According to lierature the prevalence of stunting varies in different regions of Brazil. The poorest results are found in the North and Northeast. The main determinants of linear growth retardation are poor environmental conditions and among the consequences, results indicate lower physical and mental capacity.

    Full Text Available Changes that took place in Brazil from the processes of industrialization, urbanization and, recently, pro- duction reorganization engendered many consequences on rural-urban relations, resulting in new dynamics (economic, social, cultural and political, and functionalities to the territorial cuts and their contents, giving a new meaning to them. The increasing deterioration of living conditions in Brazilian urban centers, on one hand, and the presence of new activities, functions, subjects and social players in rural areas on the other hand, has led to a revaluation of the field, perceived not only as a place for agricultural activities de- velopment, but also as place to live. Due these changes, there was the emergence of new perspectives and approaches to analysis on rural-urban relations and field-city considering other dimensions and processes not only those focused on economic activities. Taking into consideration different opportunities of analysis and theoretical-methodological cutouts on relations rural-urban and field-city is intended to analyze in this article, based on literature review and theoretical discussions, to reaffirm the importance of the peculiarities that distinguish the field and the city as well as the ways that the complementarity between these spaces can play in contemporary period.

    This study analysed the impact of changing family structure on income distribution. Specifically, it analysed how changes in the proportions of different categories of family in the population contributed to increases in the income of the richest and poorest social strata in Brazil, and the consequent impacts on income inequality. Rural and urban families were compared in order to understand how these dynamics had different impacts on more developed (urban) and less developed (rural) areas. The results emphasize how changes observed in family structure are more pronounced among the richest families, contributing to an increase in (i) the income of the richest families and (ii) income inequality between the richest and poorest families, as well as between urban and rural areas.

  13. Spatial Patterns and the Regional Differences of Rural Settlements in Jilin Province, China

    Full Text Available The spatial patterns of rural settlements are important for understanding the drivers of land use change and the relationship between human activity and environmental processes. It has been suggested that the clustering of houses decreases the negative effects on the environment and promotes the development of the countryside, but few empirical studies have quantified the spatial distribution patterns of houses. Our aim was to explore the regional differences in rural settlement patterns and expand our understanding of their geographic associations, and thus contribute to land use planning and the implementation of the policy of “building a new countryside”. We used spatial statistical methods and indices of landscape metrics to investigate different settlement patterns in three typical counties within different environments in Jilin Province, Northeast China. The results indicated that rural settlements in these three counties were all clustered, but to a varied degree. Settlement density maps and landscape metrics displayed uniformity of the settlement distributions within plain, hill, and mountainous areas. Influenced by the physical environment, the scale, form, and degree of aggregation varied. Accordingly, three types of rural settlements were summarized: a low-density, large-scale and sparse type; a mass-like and point-scattered type; and a low-density and high cluster-like type. The spatial patterns of rural settlements are the result of anthropogenic and complex physical processes, and provide an important insight for the layout and management of the countryside.

    Full Text Available The rural school crisis is a concrete fact, manifested in almost all Brazilian regions because of the continuous process of closing of schools located in rural areas. Several authors as Mennucci (2006, Werebe (1994, Maia (1992, highlighted the neglect of educational policies in relation to rural areas. However, one of the objectives of this research is to demonstrate that historically were formed two policies for rural education: one for the large property and one for the small farm. To deepen the theoretical analysis and to corroborate the proposed hypothesis, we conducted an empirical investigation having how spatial area the mesoregion of the Western Paraná. A crise da escola rural é um fato concreto, manifestado em praticamente todas as regiões brasileiras em virtude do processo continuo de fechamento dos estabelecimentos escolares localizados no espaço rural. Vários autores como Mennucci (2006, Werebe (1994, Maia (1992, destacaram o descaso das políticas educacionais em relação às zonas rurais. Todavia, um dos objetivos da presente pesquisa é demonstrar que historicamente foram se constituindo duas políticas para a educação rural: uma destinada à grande propriedade e outra para a pequena propriedade agrícola. Para aprofundarmos a análise teórica e corroborar com a hipótese formulada, realizamos uma investigação empírica tendo como recorte espacial a mesorregião Oeste do Paraná.

    Adolescence in girls has been recognized as a special period marked with the onset of menarche. Even though menstruation is a natural process, it is associated with misconceptions, malpractices and challenges among girls in developing countries. However, much is not documented; school-absenteeism and dropout are a common problem among girls in rural Ethiopia. Focusing among school girls, this study has examined knowledge about menstruation, determinants of menstrual management and its influence on school-attendance in Northeast Ethiopia. We conducted a mixed-method research combining quantitative and qualitative methods in Northeast Ethiopia. The quantitative study was conducted among 595 randomly selected adolescent school girls. Nine in-depth interviews; five school-dropout girls and four female teachers, and four focus group discussions among school girls were conducted in 2013. The mean age at menarche was 13.98 (±1.17) years. About 51% of girls had knowledge about menstruation and its management. Only a third of the girls used sanitary napkins as menstrual absorbent during their last menstruation. Girls from urban areas, had mothers of secondary and above education and, families of higher monthly expenditure had more chance of using sanitary napkins than their counterparts. More than half of the girls reported to have been absent from school during their menstruation period. Those who did not use sanitary napkins were more likely to be absent from school [AOR-95% C.I: 5.37 (3.02 - 9.55)]. Fifty eight percent of girls reported that their school-performance had declined after they had menarche. In addition, the qualitative study indicated that school-dropout was common among girls who experienced teasing and humiliation by classmates when their clothes were stained with blood as they do not use sanitary napkins. Though there is an effort to increase girls' school enrollment, lack of basic needs, like sanitary napkins that facilitate routine activates of girls
