    Full Text Available Fish reproductions were studied in two river basins (Corumbataí and Jacaré-Pepira basins in the State of São Paulo, southeastern Brazil. In the Corumbataí basin, four sites were sampled: Cabeça River, Lapa Stream, Passa-Cinco River, and Corumbataí River; in the Jacaré-Pepira basin, three sites were sampled: Tamanduá Stream, Jacaré-Pepira River, and Água Branca Stream. A total of 12 bimonthly samples were made. Fish equipment included gill nets, purse seines, sieves, and traps. The main objective of this study was to characterize the fish assemblage regarding their reproductive biology and to compare these reproductive traits between both river basins. Most individuals with gonads in stage C (mature and in stage D (empty gonads were captured in the spring and summer. Multiple spawn and parental care were common strategies, which guaranteed offspring survivorship in unstable conditions.

    Increased tourist activity in coastal regions demands management strategies to reduce impacts on rocky shores. The highly populated coastal areas in southeastern Brazil are an example of degradation caused by development of industry and tourism. Among different shore impacts, trampling has been intensively studied, and may represent a significant source of stress for intertidal fauna. A randomised blocks design was applied to experimentally study the effects of two different trampling intensities on richness, diversity, density and biomass of the rocky shore fauna of Obuseiro beach, Guarujá, southeastern Brazil. Blocks were distributed in two portions of the intertidal zone, dominated respectively by Chthamalus bisinuatus (Cirripedia) and Isognomon bicolor (Bivalvia). Blocks were trampled over three months, simulating the vacation period in Brazil and were monitored for the following nine months. Results indicate that Chthamalus bisinuatus is vulnerable to trampling impacts. Richness, diversity and turn-over index tended to be higher in trampled plots four months after trampling ceased. In general, results agree with previous trampling studies, suggesting that even low intensities of trampling may cause some impact on intertidal communities. Management strategies should include isolation of sensitive areas, construction of boardwalks, visitor education and monitoring programmes. In Brazil, additional data obtained from experimental studies are necessary in order to achieve a better understanding of trampling impacts on rocky shore communities.

    This work focuses on the geology and geochronology of rocks cropping out on Cardoso Island, on the southeastern coast of Sao Paulo State, close to the boundary with Parana State. The island, with an area of about 151 km 2 is a protected area administered by the Forest Institute of the Secretariat for the Environment of the State of Sao Paulo. It is mountainous, with a peak at 814 m, and is covered by dense Atlantic Forest vegetation. The island is made up mainly of an igneous complex with light grey leucocratic, inequigranular, medium to coarse-grained syenites. The Tres Irmaos Syenite (STI), composed of pyroxene, hornblende, and perthitic to mesoperthitic microcline, predominates has magmatic flow structures, and it cut by the pinkish grey, leucocratic medium-grained Cambriu alkali-feldspar granites (GC). Geochemical analysis of STI and GC demonstrate their metaluminous alkaline nature and late orogenic to anorogenic character. The bodies formed between 620 and 570 Ma according to U-Pb dating of zircons and cooled between 597 and 531 Ma (K-Ar in amphiboles). Whole rock Sm-Nd analyses yield Meso- and Paleoproterozoic TDM ages (1,500 - 2,200 Ma). A belt of low-grade metasedimentary rocks occurs in the northern part of the island. Quartz schist, quartz-mica schist and mica-quartz schist, often-containing andalusite and cordierite, predominate. Geochemical and geochronological data suggest that the sources of the metasediments were continental arc andesites of whose protoliths separated from the mantle between 1,800 and 2,200 Ma during the Paleoproterozoic. These metasediments probably continue on the continent in the Taquari region and extend southwards in narrow strips between the granitoids of the Paranagua Domain. (author)

    The coconut mite, Aceria guerreronis Keifer, is one of the main pests of coconut palms (Cocos nucifera) in northeastern Brazil. The objective of this study was to evaluate the levels of the coconut mite and other mites on coconut palms in the state of São Paulo and to estimate the possible role of predatory mites in the control of this pest. The effect of cultivated genotypes and sampling dates on the mite populations was also estimated. We sampled attached fruits, leaflets, inflorescences, and fallen fruits. The coconut mite was the main phytophagous mite found on attached and fallen fruits, with average densities of 110.0 and 20.5 mites per fruit, respectively. The prevalent predatory mites on attached and fallen fruits were Proctolaelaps bulbosus Moraes, Reis & Gondim Jr. and Proctolaelaps bickleyi (Bram), both Melicharidae. On leaflets, the tenuipalpids Brevipalpus phoenicis (Geijsks) and Tenuipalpus coyacus De Leon and the tetranychid Oligonychus modestus (Banks) were the predominant phytophagous mites. On both leaflets and inflorescences, the predominant predatory mites belonged to the Phytoseiidae. Neoseiulus baraki (Athias-Henriot) and Neoseiulus paspalivorus (De Leon), predators widely associated with the coconut mite in northeastern Brazil and several other countries, were not found. The low densities of the coconut mite in São Paulo could be related to prevailing climatic conditions, scarcity of coconut plantations (hampering the dispersion of the coconut mite between fields), and to the fact that some of the genotypes cultivated in the region are unfavorable for its development.

    Brazil is a non-endemic country for hepatitis E virus (HEV) infection with seroprevalence from 1% to 4% in blood donors and the general population. However, data on seroprevalence of HEV in the country are still limited. This study evaluated the prevalence of past or present HEV infection in a group of blood donors representative of the general population of the city of Sao Paulo, Southeastern Brazil. Serum samples from 500 blood donors were tested from July to September 2014 by serological and molecular methods. Anti-HEV IgG antibodies were detected in 49 (9.8%) subjects and categorized age groups revealed an age-dependent increase of HEV seroprevalence. Among the anti-HEV IgG positive subjects, only 1 had anti-HEV IgM while none tested positive for HEV-RNA. The present data demonstrate a higher seroprevalence of anti-HEV IgG than previously reported in the region. Copyright © 2017 Sociedade Brasileira de Infectologia. Published by Elsevier Editora Ltda.

    To analyze the evolution of relative prices of food groups and its influence on public healthy eating policies. Data from the municipality of Sao Paulo between 1939 and 2010 were analyzed based on calculating index numbers. Data from the Economic Researches Foundation Institute price database and weight structures (1939 to 1988) and from the Brazilian Institute of Geography and Statistics (1989 to 2010) were used to. The price database was organized, its consistency tested and prices were deflated using the consumer price index. Relative prices were calculated and associated to food categories and groups, according to the food pyramid guide adapted for the Brazilian population. The price indices for each group were calculated according to Laspeyres modified formula. The general food price index was compared with the indices for each food group and respective category: fresh food, processed food, beverages, meat, legumes, milk and eggs, cereals and root vegetables and eating out. Price indices for fat, oil, spices, sugars and sweets and processed food showed relative price reduction. Fresh food, such as fruit and vegetables, showed an increase in relative prices. Other food groups, such as cereals, flour and pasta, meat, milk and egg, showed a steadier long term trend in relative prices. The evolution of relative prices of food in the city of Sao Paulo demonstrates a negative trend towards healthy eating at household level in the long run.

    High spatial variability in polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), organochlorine pesticides, such as DDTs, and polybrominated diphenylethers was observed in plastic pellets collected randomly from 41 beaches (15 cities) in 2010 from the coast of state of São Paulo, southeastern Brazil. The highest concentrations ranged, in ng g −1 , from 192 to 13,708, 3.41 to 7554 and < 0.11 to 840 for PAHs, PCBs and DDTs, respectively. Similar distribution pattern was presented, with lower concentrations on the relatively less urbanized and industrialized southern coast, and the highest values in the central portion of the coastline, which is affected by both waste disposal and large port and industrial complex. Additional samples were collected in this central area and PCB concentrations, in ng g − 1 , were much higher in 2012 (1569 to 10,504) than in 2009/2010 (173 to 309) and 2014 (411), which is likely related to leakages of the PCB commercial mixture. - Highlights: •Organic pollutant amounts adsorbed in plastic pellets showed high variability. •Contamination suggests the influence of local sources and their transport to other sites. •Temporal changes of PCB amount are related to leakages of the commercial mixture.

    . METHODS:Cross-sectional ecological study of 96 census districts of the city of São Paulo (Southeastern Brazil in the year 2000. The data used came from the gross human rights violations database maintained by the Núcleo de Estudos de Violência (Center for the Study of Violence at the Universidade de São Paulo. This database contains information on all the cases of summary executions, lynching and police violence reported on the written press. Socioeconomic and demographic data were obtained from the 2000 Census carried out by the Instituto Brasileiro de Geografia e Estatística (Brazilian Institute of Geography and Statistics. A descriptive analysis of the data was carried out, and the association between the dependent variable - gross human rights violations (number of police violence victims, lynching episodes and summary executions -, and different socioeconomic and demographic variables was tested. In order to test this association the Spearman's correlation test was used. RESULTS: The correlations between gross human rights violations and the socioeconomic and demographic indicators were statistically significant, except for the urbanization rate and the hospital beds per 1000 inhabitants. The strongest correlations were found between the dependent variable and the following variables: size of the resident population (r=0,693, proportion of youths aged from 15 to 24 years (r=0,621, and proportion of household heads with no education or with up to three years of schooling (r=0,590. CONCLUSIONS: Gross human rights violations more markedly occur in the population with the worst living conditions. Therefore, in a scenario in which inequality in attaining social and economic rights is directly superposed to the violation of civil rights, the violence cycle is intensified and perpetuated.

La calidad de las informaciones generadas de autopsias depende del acceso a las informaciones hospitalarias.OBJECTIVE: To evaluate the quality of information registered on fetal death certificates. METHODS: Records were reviewed from 710 fetal deaths registered in the consolidated database of deaths from the State System for Data Analysis and the São Paulo State Secretary of Health, for deaths in São Paulo municipality (Southeastern Brazil during the first semester of 2008. Completeness was analyzed for variables on fetal death certificates issued by hospitals and autopsy service. The death certificates from a sub-sample of 212 fetal deaths in hospitals of the National Unified Health System (public were compared to medical records and to the records from Coroners Office. RESULTS: Among death certificates, 75% were issues by Coroners Office, with a greater frequency in public hospitals (78%. Completeness of variables on death certificates issued by hospitals was higher among non-public hospitals. There was greater completeness, agreement and sensitivity in death certificates issued by hospitals. There was low agreement and high specificity for variables related to maternal characteristics. Increased reporting of gender, birth weight and gestational age was observed in certificates issued by Coroners Office. Autopsies did not result in improved ascertainment of cause of death, with 65.7% identified as unspecified fetal death as 24.3% as intrauterine hypoxia, while death certificates by hospitals reported 18.1% as unspecified and 41.7% as intrauterine hypoxia. CONCLUSIONS: Completeness and the ascertainment of cause of fetal death need to be improved. The high proportion of autopsies did not improve information and ascertainment of cause of death. The quality of information generated by autopsies depends on access to hospital records.

    Full Text Available A survey on the use of host plants by treehoppers in plants in cerrado (savanna vegetation at Moji-Guaçu (São Paulo, Southeastern Brazil was made. Fifty-two species of treehoppers were recorded in association with 40 host plant species from October 1980 to February 1982. The families Araliaceae, Asteraceae, Leguminosae, Malpighiaceae, Myrtaceae and Nyctaginaceae were the most commonly used for oviposition. Byrsonima intermedia A. Juss. (Malpighiaceae had the highest number of associated treehopper species (10 species. The abundance of treehopper individuals was related to the hot and rainy season (from October to February, while during the cold and dry season (from March to September there was a decrease in the number of these Homoptera. After the occurrence of a frost, few adults and nymphs were observed on the host plants for one to two months.

    This paper presents an attempt to reconstruct vegetation and climate changes in the Jaguariuna and Botucatu regions (state of Sao Paulo, southeast of Brazil) during the late Pleistocene and Holocene, based on σ 13 C values of soil organic matter (SOM), 14 C dating and analysis of charcoal present in the soil profiles. Sampling sites were located under natural vegetation (cerradao), along the slopes of small hills. charcoal was found predominantly between 50 and 150 cm deep, indicating a period of greater frequency of fires in this area, between 3000 and 6000 years BP. The presence of charcoal on tops of the hills suggests that sedimentation could not be the major process responsible for burying the charcoal within the soil. Biological activity (termites, ants, earthworms) played an important role in this process. For Jaguariuna site, more enriched values of σ 13 C of SOM were observed from the late Pleistocene until mid Holocene, indicating drier climate when compared with present-day conditions. For Botucatu site, the σ 13 C profile suggests predominance of C 3 vegetation during the entire Holocene. (author)

    OBJECTIVE To describe the migration flows of demand for public and private hospital care among the health regions of the state of Sao Paulo, Brazil.METHODS Study based on a database of hospitalizations in the public and private systems of the state of Sao Paulo, Southeastern Brazil, in 2006. We analyzed data from 17 health regions of the state, considering people hospitalized in their own health region and those who migrated outwards (emigration) or came from other regions (immigration). The index of migration effectiveness of patients from both systems was estimated. The coverage (hospitalization coefficient) was analyzed in relation to the number of inpatient beds per population and the indexes of migration effectiveness.RESULTS The index of migration effectiveness applied to the hospital care demand flow allowed characterizing health regions with flow balance, with high emigration of public and private patients, and with high attraction of public and private patients.CONCLUSIONS There are differences in hospital care access and opportunities among health regions in the state of Sao Paulo, Brazil.

  12. Seismic risk map for Southeastern Brazil

    Mioto, J.A.

    1984-01-01

    During the last few years, some studies regarding seismic risk were prepared for three regions of Brazil. They were carried on account of two basic interests: first, toward the seismic history and recurrence of Brazilian seismic events; second, in a way as to provide seismic parameters for the design and construction of hydro and nuclear power plants. The first seismic risk map prepared for the southeastern region was elaborated in 1979 by 6he Universidade de Brasilia (UnB-Brasilia Seismological Station). In 1981 another seismic risk map was completed on the basis of seismotectonic studies carried out for the design and construction of the Nuclear power plants of Itaorna Beach (Angra dos Reis, Rio de Janeiro) by IPT (Mining and Applied Geology Division). In Brazil, until 1984, seismic studies concerning hydro and nuclear power plants and other civil construction of larger size did not take into account the seismic events from the point of view of probabilities of seismic recurrences. Such analysis in design is more important than the choice of a level of intensity or magnitude, or adoption of a seismicity level ased on deterministic methods. In this way, some considerations were made, concerning the use of seisms in Brazilian designs of hydro and nuclear power plants, as far as seismic analysis is concerned, recently altered over the current seismic risk panorama.

Las informaciones socioeconómicas entre expuestos y no expuestos fueron comparadas por la aplicación de la prueba de dos proporciones (α=5%. RESULTADOS: En los corredores con anchos pre-definidos la prevalencia de exposición fue de 2,4% y en los corredores calculados, fue de 1,4%. Ambos métodos indicaron mayor prevalencia de exposición en la población más joven, con menores niveles de renta y escolaridad (pOBJECTIVE: To estimate the prevalence of exposure to magnetic fields generated by transmission lines (TL and characterize the exposed population. METHODS: Information about TL in the metropolitan region of São Paulo, Southeastern Brazil, was provided by the electricity companies and mapped out using geographic information system (GIS. Demographic and socioeconomic data were obtained from the 2000 Census and added to the GIS in another layer. Households and their inhabitants that were located at a distance from the TL that was sufficient to generate a magnetic field 0.3 µT (microteslas were deemed to be exposed. The prevalence was estimated according to the area of the corridors of exposure along the TL. Two approaches were used to delimit the corridor width: one consisted of widths that were predefined by the TL voltage, and the other consisted of calculation of the magnetic field. The socioeconomic information on the exposed and non-exposed populations were compared by applying the two-proportion test (α= 5%. RESULTS: In the corridors with predefined widths, the prevalence of exposure was 2.4%, and in the calculated corridors, the prevalence was 1.4%. Both methods indicated higher prevalence of exposure among the younger population, and among individuals with lower education and income levels (p < 0

Diferentes modelos de atención psicosocial fueron encontrados, desde la constitución de "equipos-síntesis" de los cuales los usuarios no reciben alta, hasta servicios que encaminan y dan alta posterior a la estabilización de los síntomas de los usuarios, en un intento de construcción de una red de cuidados.OBJECTIVE: To describe infrastructure, human resources, and care approaches in psychosocial healthcare services. METHODS: Descriptive study including 21 psychossocial healthcare services for adults affiliated to the local health department in the city of São Paulo, Southeastern Brazil, conducted between 2007 and 2008. Information about infrastructure of facilities, human resources available and patient care was collected using a standardized instrument. There were performed descriptive data analysis and chi-square test to test the association between care activities and service source and location. RESULTS: Ten services were first created as outpatient clinics and later adapted, eight were day hospitals and only three were created as psychosocial healthcare services. None of them was open 24 hours a day. Half of them were located in rented buildings with inadequate infrastructure especially for group activities. Staff composition was very different among services, with emphasis on on-site group activities and little integration to other health services. All services provided mostly arts and cultural activities. Earlier outpatient services provided mainly craft activities and former day-hospitals offered mostly psychophysical integration activities. The profile of activities varied according to the geographical distribution of services. CONCLUSIONS: Current heterogeneous character of psychosocial healthcare services seems associated to the history of mental health care programs that have been implemented in São Paulo since 1980s and to social, economic and

  18. The Southern Divide: Testing morphological differences among bifacial points from southern and southeastern Brazil using geometric morphometrics

    Full Text Available Bifacial points have been used to characterize the “Umbu” tradition in southern and southeastern Brazil. This archaeological tradition has been related to sites dated from the late Pleistocene-early Holocene boundary to near historical times. Such a huge temporal range and vast territory have suggested the existence of greater diversity within this tradition that has been ignored thus far due to the lack of systematic regional studies of such points. Through geometric morphometric analysis, this article aims to test the hypothesis that there are substantial differences in the Holocene bifacial points associated with the Umbu tradition in southeastern Brazil. Five landmarks were digitized in standardized photographs from 658 points from the states of São Paulo, Paraná, Santa Catarina, and Rio Grande do Sul. The results show that points made by groups from southeastern Brazil (São Paulo state present a very distinct morphology (size and shape in comparison to  those made by the southern groups (Paraná, Santa Catarina and Rio Grande do Sul. This would indicate a regional identity shared only by some groups from São Paulo (at least regarding the projectile points. It is possible that Umbu tradition presents a more restricted range, both in chronological and spatial terms, than the one proposed so far.

    In this paper, our aim was to describe the process of colonization of the upper Paraná basin, southeastern Brazil, by stingrays, showing the current situation, likely trend and impact caused and discussing some management actions and mitigation measures. Interviews were held with riverbank people and health professionals, to gather information on occurrences of stingrays and accidents associated with these animals, along with underwater observations and collection of specimens, between 2004 and 2009 in localities in the States of São Paulo, Paraná and Mato Grosso do Sul, in the southeastern, southern and part of the central-western regions of Brazil. Three species of stingrays were identified in the study area, thus demonstrating that they were using the paths opened by the Tietê-Paraná Waterway to disperse. Sixteen victims of accidents involving these animals were found, mainly bathers and fishermen. Attention was drawn to the fact that these cases had not been reported, yet they presented high morbidity with notable temporary incapacity for work. This is the first report on biological invasion involving species of elasmobranchs in the literature and, because stingrays are colonizing densely populated areas and are expanding their range of distribution each year, it can be expected that their negative interactions with humans will intensify, with important changes in the epidemiological profile of accidents due to venomous animals occurring in southeastern Brazil.

MÉTODOS: Estudo descritivo, transversal, baseado em informações da Secretaria de Saúde sobre os medicamentos antineoplásicos solicitados por via judicial, com maior impacto financeiro para o Sistema Único de Saúde em 2006 e 2007. Os fármacos foram avaliados quanto às evidências clínicas de eficácia e segurança, com base na classificação do Micromedex®, em metanálises e revisões sistemáticas. As indicações foram confrontadas com aquelas aprovadas em agências reguladoras. RESULTADOS: Os medicamentos bevacizumabe, capecitabina, cetuximabe, erlotinibe, rituximabe, imatinibe e temozolomida geraram gastos superiores a R$ 40 milhões para atender 1.220 solicitações, com custo médio de R$ 33,5 mil por paciente. Os estudos selecionados não recomendam parte das indicações dos medicamentos prescritos. Cerca de 17% dos pedidos não tinham evidência para a indicação mencionada no pleito, o que equivale a um gasto inadequado de, no mínimo, R$ 6,8 milhões. CONCLUSÕES: Os resultados reforçam a necessidade de qualificação técnica para tratar as demandas judiciais e exige capacitação dos profissionais no manejo da literatura científica, na seleção adequada dos fármacos e na escolha da melhor conduta terapêutica para cada condição clínica. Dessa forma será possível garantir o acesso a tecnologias eficazes e seguras, e assim aprimorar o modelo de assistência farmacêutica em oncologia.OBJETIVO: Evaluar la racionalidad de las acciones judiciales y pedidos administrativos recibidos por la Secretaria Estatal de Salud de Sao Paulo según evidencias científicas de eficacia y seguridad.

    2013-01-01

    This paper examines the experience of Brazil in the area of health education integrated in popular education movements. More specifically, the paper discusses the link between health education and popular education, focusing in particular on the work of Paulo Freire. Anti-slavery movements, protest movements against social inequalities and the reconstruction of democracy after the end of the military dictatorship (1965-1984) provided fertile ground for a dynamic process of change--a process illustrated by the creation of the Unified Health System. These developments occurred in a context of social change and unrest. Since then, other actors and other forms of action have emerged, though creativity and popular empowerment remain central to the process of change. However, in popular education, nothing is set in stone and new issues have emerged, as Paulo Freire had predicted. The point is to recognize that popular education applied to health, or rather integrating health, is constantly changing and developing.

    Sporotrichosis is a mycotic infectious disease that is generally acquired by traumatic inoculation of contaminated materials especially from plant debris or through bites and scratches from diseased animals, such as domestic cats. It affects the skin, lymphatic system, and other organs in the warm-blooded host. Etiological agents are embedded in the plant-associated order Ophiostomatales. With essential differences between possible outbreak sources and ecological niche, host-environment interactions are classic determinants of risk factors for disease acquisition. Sporotrichosis outbreaks with zoonotic transmission, such as those that are ongoing in southern and southeastern Brazil, have highlighted the threat of cross-species pathogen transmission. Sporothrix brasiliensis has emerged as a human threat owing to the intimate contact pattern between diseased cats and humans in endemic areas. We describe the recent emergence of feline sporotrichosis in the metropolitan region of São Paulo, Brazil, with an overwhelming occurrence of S. brasiliensis as the etiological agent. A phylogenetic and a haplotype approach were used to investigate the origin of this epidemic and the impact of feline transmission on genetic diversity. During the last 3-year period, 163 cases of feline sporotrichosis were reported in São Paulo with proven S. brasiliensis culture. The haplotype diversity of feline S. brasiliensis isolates revealed the expansion of a clonal population with low genetic diversity. Haplotype analysis confirmed that isolates from São Paulo shared the haplotype originated in the long-lasting outbreak of cat-transmitted sporotrichosis in Rio de Janeiro, which differed from the haplotype circulating in the Rio Grande do Sul epidemic. The fast spread of sporotrichosis in a short period of time highlights the potential for outbreaks and suggests that the mycosis may affect an urban population with a high concentration of susceptible felines.

    Full Text Available INTRODUCTION: Cheese should be produced from ingredients of good quality and processed under hygienic conditions. Further, cheese should be transported, stored and sold in an appropriate manner in order to avoid, among other things, the incorporation of extraneous materials (filth of biological origin or otherwise, in contravention of the relevant food legislation. The aim of the study was to evaluate the hygienic conditions of "prato", "mussarela", and "mineiro" cheeses sold at the street food markets in the city of S. Paulo, Brazil. MATERIALS AND METHOD: Forty-seven samples of each of the three types of cheese were collected during the period from March, 1993 to February, 1994. The Latin square was used as a statistical model for sampling and random selection of the street markets from which to collect the cheese samples. The samples were analysed for the presence of extraneous matters outside for which purpose the samples were washed and filtered and inside, for which the methodology of enzymathic digestion of the sample with pancreatine, followed by filtering,was used. RESULTS AND CONCLUSION: Of the 141 samples analysed, 75.9% exhibited at least one sort of extraneous matters. For the "prato" and "mussarela" cheeses, the high number of contaminated samples was due mainly to extraneous matters present inside the cheese, whereas in the "mineiro" cheese, besides the internal filth, 100% of the samples had external filth.INTRODUÇÃO: Os queijos devem ser produzidos com matéria-prima de boa qualidade, processados em condições de higiene e transportados, armazenados e comercializados de forma adequada, a fim de evitar, entre outros, a incorporação de matérias estranhas (sujidades de origem biológica ou não, as quais não são permitidas pela legislação bromatológica em vigor.

    Full Text Available The invasive spotted-wing Drosophila (Diptera, Drosophilidae has been found in the city of São Paulo (Brazil. Drosophila suzukii (Matsumura, 1931, the cherry fly or spotted-wing Drosophila, a pest species from the Oriental and southeastern Palaearctic regions belonging to the melanogaster group, invaded the Nearctic and western countries of the Palaearctic regions late last decade (2008 and, more recently (2013, the southern Brazilian states of Rio Grande do Sul and Santa Catarina. Early in 2014 it was reared from blueberries produced in São Joaquim, state of Santa Catarina, that were bought at a São Paulo city grocery store. Despite being a cold-adapted species, after having arrived to the southeastern state of São Paulo, this invasive fly will probably expand its territory to other Brazilian states and South American countries through trade of cultivated soft skin small fruits, such as blueberries and strawberries, as well as naturally through the use of small wild fruits as breeding sites.

    Full Text Available A cave population of the armored catfish Isbrueckerichthys alipionis is reported from the Santana Cave, in the rio Betari watershed, Upper Ribeira karst area, Iporanga, São Paulo State, southeastern Brazil. The cave population was compared to an epigean population of I. alipionis and no significant differences where found in morphology or degree of pigmentation. As the cave population is known for at least 30 years and is apparently isolated from epigean streams, it is classified as troglophilic. The discovery of this troglophilic species in the Santana Cave is an additional strong argument for the conservation of that cave.

    High correlation between mercury (Hg) and selenium (Se) concentrations in fish organs is well known. In the present study, 58 fish samples of five fish species most commonly consumed by the Cubatao city population, Sao Paulo State, Brazil were analyzed. The Cubatao Estuary, located in southeastern Sao Paulo State, is an economically important area suffering severe environmental water quality problems due to industrial wastes, domestic sewage and solid residues. The waters of the bay suffer the impact of the immense industrial complex of Cubatao. In this study, Hg concentration in muscle, liver and kidney tissues and Se concentration in liver tissue from three predatory fish species: Macrodon ancylodon (Pescada), Menticirrhus americanus (Perna de Moca) and Micropogonias furnieri (Corvina) and two planctivorous species: Mugil liza (Tainha) and Sardella braziliensis (Sardinha) were determined. Mercury determination was performed using Cold Vapour Atomic Absorption Spectrometry (CV AAS) and selenium by Instrumental Neutron Activation Analysis (INAA). The muscle-Hg concentration variation (wet weight) was: (8 to 40 mug kg{sup -1}) - Sardinha; (12 to 62 mug kg{sup -1}) - Pescada; (3 to 23 mug kg{sup -1}) - Tainha; (43 to 184 mug kg{sup -1}) - Perna de Moca and (41 to 348 mug kg{sup -1}) - Corvina. The general concentration ranges of the analyzed elements in all species studied were (dry weight): muscle-Hg (13 to 1512 mug kg{sup -1}); liver-Hg (21 to 1804 mug kg{sup -1}); kidney-Hg 47 to 9912 mug kg{sup -1}) and liver-Se (2.10 to 43.00 mg kg{sup -1}). Se concentrations were higher than those of Hg in the liver. (author)

    In Brazil, restingas are under severe human-induced impacts resulting in habitat degradation and loss and remain one of the less frequently studied ecosystems. The main objectives of the present study are to describe the bat community in a restinga in Paulo Cesar Vinha State Park, Guarapari municipality, state of Espírito Santo, southeastern Brazil. Fieldwork was conducted twice a month from August 2004 to September 2005. A total sampling effort of 40,300 m(2)/h, represents the largest sampling effort for sampling bats in restingas to date. Bats were sampled in five different vegetational types in the area. Captured bats were processed recording information on species, sex, age, forearm length and weight. Shannon Diversity and Jaccard indexes were used to analyse diversity and similarity among habitats in the Park. A total of 554 captures belonging to 14 species and two families were obtained. Noctilio leporinus was recorded through direct observation and an ultra-sound detector also registered the presence of individuals from the family Molossidae, without being possible to distinguish it at specific level. Frugivores were the most representative guild. Richness was higher in Clusia shrubs (11 species) and Caraís lagoon (10 species). Shannon diversity index was estimated at H' = 1.43 for the overall sample, with Caraís lagoon representing the most diverse habitat (H' = 1.60). The greater similarity (J = 0.714) was observed for the two areas under high human influence.

    Highlights: → Sediment core study in the total fraction. → Elementary composition of sediment for dredged sediment regulation. → Multivariate analysis for determination of basal level of sediment composition. → Importance of the determination of local reference values for sediment studies. - Abstract: Ten sediment core samples with lengths ranging from 35 to 100 cm were collected in the Baixada Santista region and analyzed to determine As, Br, Co, Cr, Cs, Fe, Rb, Sb, Ta, Th, U, Zn and rare earths (Sc, Ce, Eu, La, Lu, Nd, Sm, Tb and Yb) level concentrations using instrumental neutron activation analysis (INAA). The studied region is located in the southeastern coast of Sao Paulo State and is comprised of a densely urbanized area, the largest industrial complex of the country, with a predominance of petrochemical and fertilizer plants. It is also home to Brazil's most important and busiest port. The conclusions found that the As, La, Sm, Ne, Ce, Eu, Hf, Ta, Th, and U elements have a high background level in the region and that Fe and Zn were the main indicators of anthropogenic contribution in the sediments.

    In the present study, mercury and selenium levels were evaluated in fish tissues and fish organs in the Santos Bay, Sao Paulo State, southeastern Brazil. Santos Bay waters are polluted by the large industrial complex of Cubatao. The estuary system filters part of this pollution before it reaches the Bay. Mercury and methylmercury determination were performed using Cold Vapor Atomic Absorption Spectrometry (CV-AAS) and selenium determination by Instrumental Neutron Activation Analysis (INAA). Methodology validation for the determination of these elements was carried out by means of reference materials analyses. There was no significant correlation between mercury and selenium concentrations (n = 17, (r2 ) R2 = 0.3482, p = 0.1709) in Cathorops spixii (bagre amarelo)- Ariidae family and Centropomus sp. (robalo)- Centropomidae family livers. Mercury and methylmercury concentrations in muscle from carnivorous species: Ariidae Cathorops spixii (bagre amarelo), Scianidae Steliffer rastifer (cangoa) and Scianidae Paralonchurus brasiliensis (maria-luiza) were determined and discussed. Total mercury concentration in Ariidae Catharops spixii livers presented the highest Hg level (7.6 mg kg-1). Although the Santos Bay is less contaminated than the inner section of its estuary system (Cubatao), it presents signs of environmental impact. (author)

    Full Text Available Procurou-se mostrar o papel da evolução urbana da cidade de São Paulo (Brasil, no surgimento das condições propícias para o estabelecimento da transmissão da esquistossomose que no Sudeste brasileiro é usualmente considerada como conseqüência do processo migratório Nordeste-Sudeste. Nas análises dos determinantes da distribuição da esquistossomose em São Paulo (Brasil, importância desmesurada tem sido atribuída ao processo migratório. O processo de expansão da doença no município de São Paulo é exemplo de uma instância em que o padrão de urbanização foi fator mais relevante do que a migração. A ocupação dos fundos de vale, a partir, do final da década de 1950, pela urbanização desordenada de São Paulo, criou condições ecológicas para o estabelecimento de focos de transmissão de esquistossomose, o que, até então, não era possível, pois a urbanização se verificava exclusivamente nas áreas mais elevadas. Sem a mudança do padrão de urbanização, a esquistossomose não teria se estabelecido no município de São Paulo, não obstante a intensa migração.The role of the urban development of the city of S.

    This aim of work is the geological and geochronological study of rocks cropping out on Cardoso Island, on the southeastern coast of Sao Paulo States, close to be boundary with Parana State. The Island with an area of about 151 km 2 is a protected area administered by the Forest Institute of Environment Secretariat of the State of Sao Paulo. It is mountanious, with a peak at 814 m, and is covered by dense Mata Atlantica vegetation. The terrains which compose the island are mainly an igneous complex with light grey leucocratic, inequigranular, medium - to coarse-grained syenites. The predominant Tres Irmaos Syenite (STI), composed of pyroxene, hornblende, and perthitic to mesoperthitic microcline, has a magmatic flow structures, and is cut by the Cambriu alkali-feldspar Granites (GC), which is pinkish grey, leucocratic and medium-grained. Geochemical analysis of STI and GC demonstrate their meta luminous alkaline nature and late-orogenic to an orogenic character. The geochronological results suggest that the bodies were formed between 620 and 570 My according to the U-Pb method in zircons, with cooling between 597 and 531 My (K-Ar in amphiboles). Whole rock Sm-Nd analysis yield T DM ages in the Meso and Paleoproterozoic (1.200 - 2.200 My). belt of low grade meta sedimentary rocks occurs in the northern part of the island. Quartz schist, quartz-mica schist and mica-quartz schist, often containing andaluzite and cordierite, predominate. The geochemical and geochronological data suggest that the sources of the metasediments were andesites of continental arc whose protolities separated from the mantle during the Paleoproterozoic, between 1.800 and 2.200 My. These metasediments probably continue on the continent in the Taquari region and extend southwards in narrow strips between the granitoids of the Paranagua Domain. Although quaternary deposits are expressive, they were not studied in details since they were not the objectives of this study. (author)

  6. Toxoplasma gondii antibodies in wild rodents and marsupials from the Atlantic Forest, state of São Paulo, Brazil

    Directory of Open Access Journals (Sweden)

    Solange Maria Gennari

    Full Text Available Toxoplasma gondii is a protozoan parasite that infects a large spectrum of warm-blooded animals, including humans. Small rodents and marsupials play an important role in the epidemiology of T. gondii because they are sources of infection for domestic and feral cats. Serum samples from 151 rodents and 48 marsupials, captured in the Atlantic Forest, São Paulo State, southeastern Brazil, were analyzed for the presence of T. gondii antibodies. Antibodies detected by the modified agglutination test (MAT ≥ 25 were found in 8.6% (13/151 of the rodents and 10.4% (5/48 of the marsupials, with titers ranging from 25 to 6400 and from 25 to 3200, respectively for the rodents and marsupials. Three of the eight species of rodents (Akodon spp., Oligoryzomys nigripesand Rattus norvegicus, and one from the four marsupial species (Didelphis aurita presented positive animals. T. gondii was described for the first time in the rodent Oligoryzomys nigripes.

    Topographic relief in southeastern Brazil consists of a sequence of stepped surfaces that formed after the fragmentation of Gondwana during the Cretaceous, Tertiary and Quaternary tectonic pulses. This region is drained by four major rivers within four major river basins, with interfluves that contain denudational escarpments, fault escarpments and mountain ranges. This study presents an analysis of the long-term evolution of two denudational escarpments, the Cristiano Otoni and the São Geraldo steps, which divide the river basins of the São Francisco, Doce and Paraíba do Sul rivers in southeastern Brazil. Denudation rates were obtained through the measurement of mean concentrations of in situ produced cosmogenic 10Be in sand-sized fluvial quartz sediments collected from granitic terrains. The rates were calculated and compared with one another and correlated to the basin-scale mean relief, slope, area, and stream power. The mean denudation rates of the Cristiano Otoni and São Geraldo highlands are 8.77 (± 2.78) m My- 1 and 15.68 (± 4.53) m My- 1, respectively. The mean denudation rates of the Cristiano Otoni and São Geraldo escarpments are 17.50 (± 2.71) m My- 1 and 21.22 (± 4.24) m My- 1, respectively. The denudation rates of the catchments of highlands that drain toward the escarpments are similar to those of their respective highlands. The results demonstrate that relief and slope have similar positive control on the denudation rates for all of the samples despite their different geomorphic context and history of landscape evolution. The São Francisco River Basin is losing area to the Doce River Basin, which, in turn, is losing area to the Paraíba do Sul River Basin.

    Hepatozoon species are vector-borne pathogens that infect domestic and wild animals. Marsupials of the species Didelphis albiventris are adapted to urban and peri-urban areas and act as reservoir hosts for several parasites. The present study evaluated the occurrence of infection by Hepatozoon species in synantropic D. albiventris from Botucatu, São Paulo, Brazil. Blood samples and ectoparasites from 19 D. albiventris were collected from urban and peri-urban areas. Hepatozoon spp. detection was performed by microscopy and molecular analysis. One opossum was positive for Hepatozoon spp. in microscopy analysis and PCR, while another animal was positive only in PCR. The obtained sequences were 100% identical to Hepatozoon canis. Six species of ticks and two species of fleas were detected on D. albiventris. This is the first report of H. canis in synantropic D. albiventris. In Brazil, H. canis transmission among dog populations is not well established, which highlights the importance of investigating the role that opossums might play in the epidemiology of this protozoan.

    Full Text Available Worldwide, indigenous peoples display a high burden of disease, expressed by profound health inequalities in comparison to non-indigenous populations. This study describes mortality patterns among the Guarani in Southern and Southeastern Brazil, with a focus on health inequalities. The Guarani population structure is indicative of high birth and death rates, low median age and low life expectancy at birth. The crude mortality rate (crude MR = 5.0/1,000 was similar to the Brazilian national rate, but the under-five MR (44.5/1,000 and the infant mortality rate (29.6/1,000 were twice the corresponding MR in the South and Southeast of Brazil. The proportion of post-neonatal infant deaths was 83.3%, 2.4 times higher than general population. The proportions of ill-defined (15.8% and preventable causes (51.6% were high. The principal causes of death were respiratory (40.6% and infectious and parasitic diseases (18.8%, suggesting precarious living conditions and deficient health services. There is a need for greater investment in primary care and interventions in social determinants of health in order to reduce the health inequalities.

    Full Text Available Necrophagous insects, mainly Diptera and Coleoptera, are attracted to specific stages of carcass decomposition, in a process of faunistic succession. They are very important in estimating the postmortem interval, the time interval between the death and the discovery of the body. In studies done with pig carcasses exposed to natural conditions in an urban forest (Santa Genebra Reservation, located in Campinas, State of São Paulo, southeastern Brazil, 4 out of 36 families of insects collected - Calliphoridae, Sarcophagidae, Muscidae (Diptera and Dermestidae (Coleoptera - were considered of forensic importance, because several species were collected in large numbers both visiting and breeding in pig carcasses. Several species were also observed and collected on human corpses at the Institute of Legal Medicine. The species belonged to 17 different families, 6 being of forensic importance because they were reared from human corpses or pig carcasses: Calliphoridae, Sarcophagidae, Muscidae, Piophilidae (Diptera, Dermestidae, Silphidae and Cleridae (Coleoptera. The most important species were: Diptera - Chrysomya albiceps, Chrysomya putoria, Hemilucilia segmentaria, Hemilucilia semidiaphana (Calliphoridae, Pattonella intermutans (Sarcophagidae, Ophyra chalcogaster (Muscidae, Piophila casei (Piophilidae; Coleoptera - Dermestes maculatus (Dermestidae, Oxyletrum disciolle (Silphidae and Necrobia rufipes (Cleridae.

    This is a quantitative, descriptive study that aims to investigate work-related injuries involving exposure to biomaterial among health workers in health care units in the city of Ribeirão Preto, São Paulo, southeastern Brazil. Data was obtained from Work-Related Injury Report forms filled at the Worker's Health Reference Center in Ribeirão Preto in 2005. A total of 1,665 work-related injuries (91.7%) were reported and 151 (8.3%) were diagnosed as occupational diseases. Of the 1,665 injuries reported, 480 (28.82%) affected workers working at health care units and 153 (31.87%) were associated to biological material exposure. The situational diagnosis of occupational accidents is relevant for the development of preventive strategies by worker's health services. The results of the present study provide major indicators that allow the organization of actions following the National Network for Workers' Comprehensive Health Care (RENAST) guidelines and effectively contribute for workers health promotion.

    Full Text Available This study reports the rediscovery of Holoaden luederwaldti Miranda-Ribeiro, 1920 and provides information on the distribution, sexual dimorphism, reproduction and vocalization of a population of this species in Campos do Jordão, São Paulo (southeastern Brazil. Sampling was carried out in the Parque Estadual de Campos do Jordão (PECJ from October 2005 through December 2008. Collecting was conducted using pitfall traps with a drift-fence on different altitudinal gradients (1,540 m, 1,780 m and 2,000 m a.s.l.. Fifty-two specimens of H. luederwaldti were collected in the PECJ. The mean snout-vent length (SVL was 36.17 mm for males and 42.61 mm for females, indicating sexual dimorphism in body size. Holoaden luederwaldti occurred during the warm-rainy months. The population was distributed between 1500 and 2000 m, and the greater abundance was registered in well preserved forest areas. Mature females contained from 36 to 41 oocytes and the mean of oocyte diameter was 3.72 mm. The advertisement call of H. luederwaldti consists of simple notes composed of three harmonics. The record of the population of H. luederwaldti in the PECJ has reinforced the importance of investigating different areas of the forest when conducting faunal surveys.

  14. Does the reproductive season account for more records of birds in a marked seasonal climate landscape in the state of São Paulo, Brazil?

    2013-01-01

    Full Text Available Investigators have reported that birds from temperate regions are more detectable during their breeding seasons, which should be used to adequately survey avifaunas. In the state of São Paulo, southeastern Brazil, the rainiest months of the year are usually associated with a peak in the reproduction of birds. To test the hypothesis that birds are equally detectable throughout the year, I conducted transect counts of birds in a predominantly open Cerrado landscape in São Paulo during 2005 and 2006. There was no significant difference in the number of species or individuals between breeding (rainy and nonbreeding (dry seasons; 24% of the species with > 50 contacts was likely to be recorded more often in a particular season. Unlike temperate regions, where vocal behavior plays an important role in detections of birds during and after reproductive seasons, my results suggest that Cerrado birds may be evenly detected throughout the year.

    Rb-Sr, Pb-Pb and U-Pb geochronologic studies carried out on precambrian rocks from the southeastern Sao Paulo state suggest a Complex geologic evolution during the Archean and Proterozoic times. This region is divided in five differents allochthonous terranes named Itapira-Amparo, Piracaiba-Jundiai, Sao Roque, Embu and Costeiro, separated by thrust and strike-slip faults. The Itapira-Amparo domain has a original history dating back to 3.4 Ga. and since 2.6 to 2.5 Ga. and 2.2 to 1.9 Ga. metamorphic rockformation episode occurred involving both mantle-derived magmas and recycled material. Supracrustal sequences developed around 1.4 Ga. The domain was locally reworked in 0.8 - 0.65 Ga. In the Piracaia-Jundiai the main rock-formation event occurred at 1.4 Ga., but this domian was affected by strong granization and migmatization episodes during the period 1.1 - 0.6 Ga. The third terrain is characterized by the Sao Roque metavolcanossedimentary sequence developed during the time period 1.8 - 0.7 Ga., and comprising two metamorphic superimposed events (1.4 and 0.8 - 0.7 Ga.). the post-tectonics granites ranging in ages from 0.7 to 0.55 Ga. Within the Embu terrain ages of 2.5, 1.4 and 0,75 Ga. were obtained for the metamorphic terrain, with post-tectonic activities around 650 Ma. In the Costeiro domain all the metamorphic rocks developed in late-Proterozoic time, with syntectonic phase around 650 Ma [pt

    The use of carbon isotopes in studies of soil organic matter (SOM) dynamics have been applied to infer information about vegetation and climate changes during the late Quaternary (Schwartz et al., 1986; Pessenda et al., 1996). This approach had also been used in different areas in Brazil to document vegetation changes during the Holocene (Desjardins et al., 1996; Gouveia et al., 1997; Pessenda et al., 1998a, b, 2001) and late Pleistocene/Holocene (Freitas et al., 2001). The application of carbon isotopes is based on the different 13 C composition of C 3 and C 4 plants and its preservation in SOM. 13 C values of C 3 plant species range from approximately -32% o to -20% o PDB, with a mean of -27% o . In contrast, δ 13 C of C 4 species range from -17% o to -9% o with mean of -13% o . Thus, C 3 and C 4 plant species have distinct δ 13 C values and differ from each other by approximately 14% o (Boutton, 1991). The study of charcoal fragments found in sediments and soils also supplies information about climatic conditions. Charcoal distribution in the soil profiles can provide information about the occurrence of paleofires (Pessenda et al., 1996), possibly associated with drier climate periods and/or human disturbance. In this paper we report δ 13 C data of soil and 14 C dates on charcoal from five soil profiles collected under natural vegetation in the Parana and Sao Paulo states, southeastern Brazil. Carbon isotopes are used to evaluate vegetation changes during the late Pleistocene and Holocene. Charcoal distribution in the soil and its dating are used to infer linkage between forest fires and climate changes and to establish the chronology (au)

    Studies on hospital morbidity among Brazilian indigenous peoples are relatively recent, show limited coverage, and lack data sources capable of generating specific indicators according to ethnic group. The current study describes hospital morbidity in the indigenous population living in 83 Guarani villages in Southern and Southeastern Brazil (N=6,483), based on primary data obtained from a hospital admissions surveillance system implemented in 2007-2008, specifically for a case-control study on acute respiratory infections (ARI) in Guarani children. During the study period there were 666 hospitalizations in a total of 497 individuals, the majority under 5 years of age (71.9%). Respiratory illnesses were the main causes of hospitalization (64.6%), especially in children (<5 years: 77.6%; <1 year: 83.4%) and exceeded the proportions of hospital admissions from these causes in other indigenous groups. The overall hospitalization rate (per 100 person-years) was 8.8, or 71.4 under 1 year and 21.0 from 1 to 4 years of age. The ARI hospitalization rate (5.3) was 6.5 and 2.0 times higher than for diarrhea and other causes, respectively, while in children under 5 years of age (ARI=23.7) these differences were 7.4 and 5.4 times, respectively. The standardized Guarani hospitalization rate exceeded the standardized rates for the South and Southeast of Brazil by 40% and 210%, respectively. Hospitalization for primary care sensitive conditions and the high ARI rates indicate the need for studies to understand the epidemiology of ARI and investments to upgrade primary health care for the Guarani.

    Full Text Available Studies on the sociality of heterospecific assemblages of birds have promoted a greater understanding of the types of interactions and survivorship between coexisting species. This study verified the group compositions in bird assemblages and analyzed the sociality of migratory and resident species on sandy beaches of southeastern Brazil. A transect was established on the median portion of beaches and all the groups of bird species (monospecific, heterospecific and solitary individuals were registered four days per month from November 2006 to April 2007. The sociality of each species was calculated by its frequency in heterospecific groups, its proportional number of contacts with other species in heterospecific groups, and the number of species that it associated with. Semipalmated Sandpiper Calidris pusilla (Linnaeus, 1766 and Semipalmated Plover Charadrius semipalmatus Bonaparte, 1825 (both migratory had the highest degree of sociality and did not show a preference to associate with either residents or migratory species. Sanderling Calidris alba (Pallas, 1764 (migratory occupied the third position in the sociality rank and associated with migratory species frequently. Southern Caracara Carara plancus (Miller, 1777 and Black Vulture Coragyps atratus (Beschstein, 1793 (both resident were uniquely found among heterospecific groups with necrophagous and resident species. Kelp Gull Larus dominicanus Lichtenstein, 1823 (resident associated more frequently with resident species. The sociality in assemblages of birds may promote advantages such as an increased collective awareness in dangerous situations and indication of sites with abundant food sources.

The results are interpreted in terms of the main synoptic patterns associated with thunderstorm activity in this region, indicating that the prevailing synoptic pattern associated with thunderstorm activity is the occurrence of frontal systems and their modulation by the South Atlantic Convergence Zone (SACZ and topography. Evidence of urban effects is also found. The results are also discussed in the context of practical applications involving their use in the Brazilian lightning protection standards, suggesting that the present version of the Brazilian standards should be revised incorporating RINDAT and LIS data. Finally, the results are important to improve our knowledge about the limitations of the different techniques used to record the thunderstorm activity and support future climatic studies.

    Full Text Available Minas Gerais is the largest one out of the four states that comprise the southeastern region of Brazil, with the bigest goat herd of this region. The characterization of health aspects of dairy goat husbandry was done in 84 dairy herds in 81 municipalities and 200 beef herds in 70 municipalities in the State of Minas Gerais. A questionnaire was filled out for each herd, requesting data regarding the farm, the herd and the farmer by the veterinarians within the Agriculture and Livestock Institute of Minas Gerais (Instituto Mineiro de Agropecuária – IMA. A data bank was developed in Windows Excel and analyzed using the Epi-Info system. Comparisons of categorical variables were based on Chi-square test. The individual identification of the animals was done at 73.8% of dairy farms and at 7.5% of beef farms, use of quarentine at 15.5% and 4.0%, isolation of sick animals at 30.9% and 11.0%, requisition of sanitary certificate in the acquisition of new animals at 28.6% and 1.5%, regular veterinary monitoring at 52.4% and 1.5%, respectively. The main health problems reported at dairy and beef farms, respectively, were abortion (50.0% and 49.5%, mastitis (41.7% and 19.0%, pneumonia (37.4% and 16.5%, diarrhea (34.5% and 16.5% and caseous lymphadenitis (20.2% and 43.0%.

    Air pollution is an important problem for São Paulo city and vehicles are the main source. About 11 million people are exposed to this pollution. To examine studies realized about air pollution and its effects on health of the population of São Paulo (Brazil) and methods of assessing exposure to pollution related to traffic. We performed a literature review using the keywords "air pollution", "São Paulo", and traffic-related air pollution. As results were obtained several studies that found relation between air pollution in São Paulo and respiratory and cardiovascular problems, fetal growth, increased mortality and hospitalizations, particularly in children and elderly people. In order to estimate the exposure, most of these studies consider the isotropic distribution of pollutants throughout the area, what prevents the evaluation of and the influence of traffic. Several methods have been used to analyze the air traffic exposure, which can be used isolated or combined. It is believed that the combination of models used to calculate pollutant concentrations to methods of georeferencing is the most appropriate approach for similar studies in São Paulo. The advantages of these methods are the ability to identify priority areas and situations, obtaining detailed information for adoption of public policies or measures, and to simulate different scenarios. The application of these methods in studies at São Paulo depends on the improvement of input data, air quality meteorological monitoring net enhancement and data of traffic volume.

    Brazilian shellmounds are archaeological sites with a high concentration of marine faunal remains. There are more than 2000 sites along the coast of Brazil that range in age from 8,720 to 985 cal BP. Here, we studied the ichthyoarchaeological remains (i.e., cranial/postcranial bones, otoliths, and teeth, among others) at 13 shellmounds on the southern coast of the state of Rio de Janeiro, which are located in coastal landscapes, including a sandy plain with coastal lagoons, rocky islands, islets and rocky bays. We identified patterns of similarity between shellmounds based on fish diversity, the ages of the assemblages, littoral geomorphology and prehistoric fisheries. Our new radiocarbon dating, based on otolith samples, was used for fishery characterization over time. A taxonomical study of the ichthyoarchaeological remains includes a diversity of 97 marine species, representing 37% of all modern species (i.e., 265 spp.) that have been documented along the coast of Rio de Janeiro state. This high fish diversity recovered from the shellmounds is clear evidence of well-developed prehistoric fishery activity that targeted sharks, rays and finfishes in a productive area influenced by coastal marine upwelling. The presence of adult and neonate shark, especially oceanic species, is here interpreted as evidence of prehistoric fisheries capacity for exploitation and possibly overexploitation in nursery areas. Various tools and strategies were used to capture finfish in seasonal fisheries, over rocky reef bottoms and in sandy littoral environments. Massive catches of whitemouth croaker, main target dermersal species of South Atlantic coast, show evidence of a reduction in body size of approximately 28% compared with modern fisheries. Fishery activity involving vulnerable species, especially in nursery areas, could mark the beginning of fish depletion along the southeastern Brazilian coast and the collapse of natural fish populations.

    Full Text Available In order to evaluate the pollination strategies of Bignoniaceae, the floral biology and the floral visitors in five species, three cerrado shrubs (Arrabidaea brachypoda (DC. Bor., Jacaranda decurrens Cham., and Jacaranda oxyphylla Cham., and two lianas from the border of a semideciduous seasonal forest (Arrabidaea samydoides (Cham. Sandw., and Arrabidaea triplinervia H. Baill. were studied in Botucatu, São Paulo State, Southeastern Brazil. The flowering periods were partially overlapping, especially between species in the same habitat. All the five species were functionally allogamous, melittophilous, nototribic and mainly pollinated by long tongued large bees. Some medium-sized and small pollen-foraging bees were occasional legitimate visitors, whereas others visitors were robbers/thieves. Each species showed a particular set of pollinators. Only two pollinator species were observed in more than one bignon. There was no partition of pollinators even among the species of bignons blooming at the same time at the same habitat.Com objetivo de avaliar as estratégias de polinização de espécies de Bignoniaceae, foram estudados a biologia floral e os visitantes florais de cinco espécies, três arbustivas do cerrado (Arrabidaea brachypoda (DC.

    2015-08-01

    We examined 42 maned wolf scats in an unprotected and disturbed area of Cerrado in southeastern Brazil. We identified six helminth endoparasite taxa, being Phylum Acantocephala and Family Trichuridae the most prevalent. The high prevalence of the Family Ancylostomatidae indicates a possible transmission via domestic dogs, which are abundant in the study area. Nevertheless, our results indicate that the endoparasite species found are not different from those observed in protected or least disturbed areas, suggesting a high resilience of maned wolf and their parasites to human impacts, or a common scenario of disease transmission from domestic dogs to wild canid whether in protected or unprotected areas of southeastern Brazil.

E-mail: carolinespitz@yahoo.com.br The parabasalid flagellate Tritrichomonas foetus is recognized as the causative agent of large bowel diarrhea in domestic cats. A second species of parabasalid flagellate Pentatrichomonas hominis, has also been reported in association with domestic cats, albeit almost exclusively as a commensal organism. However, there is growing evidence to suggest that P. hominis may also be involved in feline gastro-intestinal disorders including diarrhea and that the incidence of infection with P. hominis may have been underestimated due to it being misidentified as T. foetus. The aim of the current study was to establish the basis for routine morphological identification of P. hominis employing light microscopy and to apply the methodology to the examination of cases of diarrhea in a laboratory population of Brazilian domestic cats (n =39. A detailed morphological description of P. hominis isolated from 11 cats with diarrhea was produced and molecular analyses were performed in support of the morphological data and to demonstrate the absence of T. foetus in infected cats. All animals with diarrhea were demonstrated to be infected solely with P. hominis. The findings of the current study provide a straight forward and validated method for the differential diagnosis of P. hominis and contribute to the on-going debate surrounding the pathogenic potential of this parabasalid flagellate.

    A monitoring of thunderstorm in urban areas occurred in the vicinity of Sao Bernardo do Campo, Sao Paulo from November 2004 to March 2005. Eight thunderstorms were monitored by local electric field, video camera, Brazilian Lightning Location Network (RINDAT) and weather radar. The most of these thunderstorms were associated with the local convection and cold front. Some of these events presented floods in the vicinity of Sao Bernardo and in the Metropolitan Area of Sao Paulo (MASP) being associated with local sea breeze circulation and the heat island effect. The convectives cells exceeding 100km x 100 km of area, actives between 2 and 3 hours. The local electric field identified the electrification stage of thunderstorms, high transients of lightning and total lightning rate of above 10 flashes per minute. About 29.5 thousands of cloud-to-ground lightning flashes were analyzed . From the total set of CG flashes analyzed, about 94 percent were negative strokes and presented average peak current of above 25kA, common for this region. Some lightning images were obtained by video camera and compared with transients of lightning and lightning detection network data. The most of these transients of lightning presented continuing current duration between 100ms and 200ms. A CG lightning occurred on 25th February was visually observed 3.5km from FEI campus, Sao Bernardo do Campo. This lightning presented negative polarity and estimed peak current of above 30kA. A spider was visually observed over FEI Campus at 17th March. No transients of lightning and recording by lightning location network were found.

    Full Text Available To study forest composition and structure, as well as to facilitate management plans and monitoring programs, we conducted a phytosociological survey in the PE Caverna do Diabo State Park and the Quilombos do Médio Ribeira Environmentally Protected Area, both located within the state of São Paulo, Brazil. We analyzed 20 plots of 400 m² each, including only individuals with a circumference at breast height > 15 cm. We employed cluster analysis and ordination (principal component analysis and correspondence analysis, including species data and abiotic data. We evaluated 1051 individuals, belonging to 155 species in 48 families. Of those 155, 18 were threatened species, 33 were endemic species, and 92 (59.4% were secondary species. The overall Shannon index was 4.524, one of the highest recorded for a dense rainforest in southeastern Brazil. We found that our sample plots fell into three blocks. The first was forest in which there had been human disturbance, showing low species richness, minimal density, and a small relative quantity of biomass. The second was undisturbed mature forest, showing a comparatively larger quantity of biomass. The third was mature forest in which there had been natural intermediate disturbance (dead trees, showing higher species richness and greater density. We identified various groups of species that could be used in monitoring these distinct forest conditions.

  16. Recommendations for monitoring avian populations with point counts: a case study in southeastern Brazil

    Directory of Open Access Journals (Sweden)

    Vagner Cavarzere

    2013-01-01

    Full Text Available In the northern hemisphere, bird counts have been fundamental in gathering data to understand population trends. Due to the seasonality of the northern hemisphere, counts take place during two clearly defined moments in time: the breeding season (resident birds and winter (after migration. Depending on location, Neotropical birds may breed at any time of year, may or may not migrate, and those patterns are not necessarily synchronous among species. Also in contrast to the northern hemisphere, population trends and the impact of rapid urbanization and deforestation are unknown and unmonitored. Throughout one year, we used point counts to better understand temporal patterns of bird species richness and relative abundance in the state of São Paulo, southeastern Brazil, to examine how to implement similar bird counts in tropical America. We counted birds twice each day on 10 point transects (20 points day‑1, separated by 200 m, with a 100 m limited detection radius in a semideciduous tropical forest. Both species richness and bird abundance were greater in the morning, but accumulation curves suggest that longer-duration afternoon counts would reach the same total species as in morning counts. Species richness and bird abundance did not vary seasonally and unique species were counted every month; relatively few species (20% were present in all months. Most (84% known forest species in the area were encountered. We suggest that point counts can work here as they do in the northern hemisphere. We recommend that transects include at least 20 points and that the simplest timing of bird counts would also be seasonal, using timing of migration of austral migrants (and six months later to coordinate counts. We propose that bird counts in Brazil, and elsewhere in Latin America, would provide data to help understand population trends, but would require greater effort than in temperate latitudes due to greater species richness and different dynamics of

    This aim of work is the geological and geochronological study of rocks cropping out on Cardoso Island, on the southeastern coast of Sao Paulo States, close to be boundary with Parana State. The Island with an area of about 151 km{sup 2} is a protected area administered by the Forest Institute of Environment Secretariat of the State of Sao Paulo. It is mountanious, with a peak at 814 m, and is covered by dense Mata Atlantica vegetation. The terrains which compose the island are mainly an igneous complex with light grey leucocratic, inequigranular, medium - to coarse-grained syenites. The predominant Tres Irmaos Syenite (STI), composed of pyroxene, hornblende, and perthitic to mesoperthitic microcline, has a magmatic flow structures, and is cut by the Cambriu alkali-feldspar Granites (GC), which is pinkish grey, leucocratic and medium-grained. Geochemical analysis of STI and GC demonstrate their meta luminous alkaline nature and late-orogenic to an orogenic character. The geochronological results suggest that the bodies were formed between 620 and 570 My according to the U-Pb method in zircons, with cooling between 597 and 531 My (K-Ar in amphiboles). Whole rock Sm-Nd analysis yield T{sub DM} ages in the Meso and Paleoproterozoic (1.200 - 2.200 My). belt of low grade meta sedimentary rocks occurs in the northern part of the island. Quartz schist, quartz-mica schist and mica-quartz schist, often containing andaluzite and cordierite, predominate. The geochemical and geochronological data suggest that the sources of the metasediments were andesites of continental arc whose protolities separated from the mantle during the Paleoproterozoic, between 1.800 and 2.200 My. These metasediments probably continue on the continent in the Taquari region and extend southwards in narrow strips between the granitoids of the Paranagua Domain. Although quaternary deposits are expressive, they were not studied in details since they were not the objectives of this study. (author)

    During the Brasiliano-Pan-African Orogeny, West Gondwana formed by collisional processes around the São Francisco-Congo Craton. The Ribeira belt, in southeastern Brazil, resulted from northwestward collision (650-600 Ma), followed by large-scale northeast-southwest dextral strike-slip shear movements related to late-collisional escape tectonics ( ca 600 Ma). In São Paulo State, three groups, also interpreted as terranes, are recognised in the Ribeira Belt, the Embu, Itapira and São Roque Groups. The Embu and Itapira Groups are formed of sillimanite-gneisses, schists and migmatites intruded by Neoproterozoic calc-alkaline granitoids, all thrusted northwestward. The São Roque Group is composed of metasediments and metavolcanics in greenschist-facies. Its deformation indicates a transpressional regime associated with tectonic escape. Sub-alkaline granites were emplaced in shallow levels during this regime. Microstructural studies along the Itu, Moreiras and Taxaquara Shear Zones demonstrate the coexistence of horizontal and vertical displacement components during the transpressional regime. The vertical component is regarded as responsible for the lateral juxtaposition of different crustal levels.

    The use of alcohol fuel has received much attention since the 1980s. In Brazil, ethanol-fuelled vehicles have been currently used on a large scale. This paper reports the atmospheric methanol and isoproponal concentrations which were measured from May to December 1997, in Osaka, Japan, where alcohol fuel was not used and from 3 to 9 February 1998 in Sao Paulo, Brazil, where ethanol was used. The alcohols were determined by the alkyl nitrite formation reaction using gas chromatography (GC-ECD) analysis. The concentration of atmospheric alcohols, especially ethanol, measured in Sao Paulo were significantly higher than those in Osaka. In Osaka, the average concentrations of atmospheric methanol, ethanol, and isopropanol were 5.8 ± 3.8, 8.2 ± 4.6, and 7.2 ± 5.9ppbv, respectively. The average ambient levels of methanol, ethanol, and isopropanol measured in Sao Paulo were 34.1± 9.2, 176.3 ± 38.1, and 44.2 ± 13.7ppbv, respectively. The ambient levels of aldehydes, which were expected to be high due to the use of alcohol fuel, were also measured at these sampling sites. The atmospheric formaldehyde average measured in Osaka was 1.9± 0.9ppbv, and the average acetaldehyde concentration was 1.5 ± 0.8ppbv. The atmospheric formaldehyde and acetaldehyde average concentrations measured in Sao Paulo were 5.0 ± 2.8 and 5.4 ± 2.8ppbv, respectively. The C 2 H 5 OH/CH 3 OH and CH 3 CHO/HCHO were compared between the two measurement sites and elsewhere in the world, which have already been reported in the literature. Due to the use of ethanol-fuelled vehicles, these ratios, especially C-2H 5 OH/CH 3 OH, are much higher in Brazil than those measured elsewhere in the world. (Author)

    Full Text Available The purpose of the study was to describe cyclists and cycling trips, and to explore correlates, time trends and health consequences of cycling in São Paulo, Brazil from 1997 to 2012. Cross-sectional analysis using repeated São Paulo Household Travel Surveys (HTS. At all time periods cycling was a minority travel mode in São Paulo (1174 people with cycling trips out of 214,719 people. Poisson regressions for individual correlates were estimated using the entire 2012 HTS sample. Men were six times more likely to cycle than women. We found rates of bicycle use rising over time among the richest quartile but total cycling rates dropped from 1997 to 2012 due to decreasing rates among the poor. Harms from air pollution would negate benefits from physical activity through cycling only at 1997 air pollution levels and at very high cycling levels (≥9 h of cycling per day. Exposure-based road injury risk decreased between 2007 and 2012, from 0.76 to 0.56 cyclist deaths per 1000 person-hours travelled. Policies to reduce spatial segregation, measures to tackle air pollution, improvements in dedicated cycling infrastructure, and integrating the bicycle with the public transport system in neighborhoods of all income levels could make cycling safer and prevent more individuals from abandoning the cycling mode in São Paulo.

    Sao Paulo is the largest city in Brazil with about 19 millions of inhabitants in the metropolitan area, more than 8 million motor vehicles and strong industrial activity at the metropolitan region, which are responsible for increasing pollution in the region. Nevertheless, there is little information on metal contents in the metropolitan region soils, which would be very useful as a fingerprint of the environmental pollution. The present study aimed to determine As, Ba, Co, Cr, Sb and Zn concentrations in soils adjacent to avenues of highly dense traffic downtown Sao Paulo city: Consolacao/Reboucas Avenues; 23 de Maio Avenue and Tiradentes Avenue, to assess their possible sources and potential environmental impact. The analytical technique employed was Instrumental Neutron Activation Analysis (INAA). The results show metal concentration levels higher than the values reference values for soils of Sao Paulo, according to the Environmental Protection Agency of the State Sao Paulo (CETESB) guidelines. As, Ba and Zn showed concentration levels above the Intervention Values in some points, indicating direct or indirect potential risks to human health. The traffic related element Ba, Sb and Zn presented concentrations above the Prevention Values in points with high density traffic and may be associated to vehicular emissions. (author)

    Full text: For proper management of soil and groundwater quality, background levels of toxic elements in a given ecosystem must be known. The main aim of the present study is to perform a radioactive characterization of representative soils from the Sao Paulo State, in order to determine background levels for some selected radionuclides, which could be used as a quality reference value. Soil types and sampling places were chosen according to their representativeness and spatial distribution in the State geological formations, taking also into account their nearness to large urban areas. Thirty samples were collected in areas presenting low antrophic perturbation - native vegetation or ancient reforestation -, minimizing the chances that selected areas could have sustained antrophic effects in recent past. Activity concentration of U-nat, Th-nat, 228 Th, 228 Ra, 226 Ra, 210 Pb, 137 Cs and 40 K were evaluated and correlated with soil mineralogical characteristics. The samples were measured by means of passive gamma spectrometry and spectrophotometry, employing Arsenazo III. Results showed a wide variation on background levels for natural radionuclides of the uranium and thorium series, and very low concentration of 137 Cs from radioactive fallout, ranging from -1 for U-nat, 8 to 82 Bq.kg -1 for Th-nat, 4.8 to 120 Bq.kg -1 for 228 Th, 3.3 to 97.6 Bq.kg -1 for 228 Ra, 1.0 to 61.8 Bq.kg -1 for 226 Ra, -1 for 210 Pb, 0.8 to 4.1 Bq.kg -1 for 137 Cs and 15.3 to 516 Bq.kg -1 for 40 K. No significant correlation could be observed between the clay, silt and sand content in the samples and the respective activity concentration of the radionuclides. (author)

    2002-01-01

    Full Text Available A study of the associations between three species of rodents in the Atlantic forest and their parasitic arthropods was undertaken at the Juréia-Itatins Ecological Station, located in the State of São Paulo, Southeastern Brazil, from March 1989 to February 1990. Individuals of three species, Oryzomys russatus, Proechimys iheringi and Nectomys squamipes were captured and examined for ectoparasites. Eleven species of parasitic arthropods were found, including four species of insects and seven of Acari. Parasitism intensity, phenology, and rainfall were positively correlated with the abundance of the ectoparasites and their hosts. The most abundant host was O. russatus (Muridae: Sigmodontinae, and the most common parasite on it was the laelapid mite Gigantolaelaps oudemansi. The cuterebrid Metacuterebra apicalis caused myiasis in O. russatus. A mutualistic association between the staphylinid beetle Amblyopinus sp. and its host P. iheringi (Echimyidae was observed. The few N. squamipes captured had small numbers of ectoparasites.

    Full Text Available In recent years, attacks by piranhas have become a common problem in dammed portions of rivers and streams in the State of Sao Paulo, Southeastern Brazil. In two outbreaks recorded in two neighboring counties in the Northwest region of the state, 74 bathers were bitten. Only one bite per person was recorded during a short period of the year. The bites were related to parental care and/or defense of spawning territory, which confirms previous studies and demystify the attacks by these legendary fish, as they are perceived by most people. Placement of fine mesh nets and removal of aquatic vegetation stopped the attacks.Ataques por piranhas vêm se tornando um problema comum em trechos represados de rios e córregos no estado de São Paulo, Sudeste do Brasil. Em dois surtos ocorridos em dois municípios vizinhos no noroeste do estado, 74 banhistas foram mordidos. Uma mordida por pessoa foi registrada, em curto período do ano. As mordidas estão relacionadas a cuidado parental e/ou defesa do território de desova, o que reforça estudos anteriores e desmistifica os ataques por este peixe lendário, da maneira como são popularmente percebidos. A colocação de redes de malha fina e a remoção de vegetação aquática cessaram os ataques.

    Full Text Available This paper focuses on Hotels for dogs and cats in São Paulo city. Characteristics and tendencies are analyzed aiming to contribute to applied studies on the subject. It begins by bringing general data on pet market in the world and on hotels for pets in Brazil. Pets hosting is assessed through registers on the subject and interviews with managers of that kind of hotels, as well as with pet owners living in the southern part of São Paulo city. It could be stated that pet hosting is a rising market for two segments: a exclusive pet hosting and b shared hosting (people with their pets. Hotel products and services for pets mean both broadening of the hospitality concept, and diversification. It means also new professionals are needed at managerial and operational levels to attend pet owners´ expectations and pets comfort themselves.

  8. Mortality from asthma in the state of S. Paulo, Brazil (1970-1992

    Full Text Available Mortality from asthma has shown important variations over time in several countries. In Brazil, a mortality study performed in the 60s, covering the cities of S.Paulo and Ribeirão Preto, and other ten cities showed that S.Paulo presented the lowest death rate from asthma among of them all. It was decided to study the time trends of deaths from asthma and from the whole set of respiratory diseases from 1970 to 1992, in the population aged 15-34 yrs. old in the State of S.Paulo, as well as to compare them with those of other countries. Asthma mortality rates during the 23 years of observation since 1975, showed an oscillatory declining pattern with a peak of deaths in the initial years. The linearization of the curve allows the calculation of Pearson's correlation coefficient that was significantly negative, suggesting a decline in the mortality over this period, mainly in the 5-9 yrs. old and 30-34 yrs. old strata. The segmentation of data between the period of ICD-9, 1970 to 1978, and of ICD-9, 1979 and subsequent years, shows that there is stability within each period, in all age-groups, except for that of 5-9 yr. olds between 1970-1978. Comparing the rates of the population aged 15-34 yrs. old for the State of S. Paulo, Brazil, with trends observed in 14 other countries, an intermediate pattern for the first triennial period (1970-1972 as well as for the subsequent triennial periods, emerges. A prevalence study of asthma, a follow up program meant for using emergency rooms and a surveillance of deaths due to all respiratory diseases and specifically to asthma are strongly recommended.

    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.

MÉTODOS: Estudou-se amostra domiciliar de menores de cinco anos do Município de São Paulo (n=584 em 1995 e 1996. O diagnóstico de anemia (hemoglobina OBJECTIVE: To evaluate the influence of the consumption of cow's milk on the risk of anemia during childhood in the city of São Paulo. METHODS: We have studied a probabilistic sample (n=584 of underfive children living in the city of São Paulo, southeastern Brazil, between 1995 and 1996. Anemia (hemoglobin <11g/dl was diagnosed using capillary blood obtained by fingertip puncture. The cow's milk content and the density of heme and nonheme iron in the child's diet were obtained using 24-hour recall questionnaires. Multiple linear and logistic regression models were used to study the association between cow's milk content in the diet and hemoglobin concentration or risk of anemia, and included statistical control for potential confounders (age, sex, birthweight, presence of intestinal parasites, family income, and mother's schooling. RESULTS: The prevalence of anemia was 45.2% and the mean contribution of milk to the total caloric content of the children's diets was 22.0%. The association between milk consumption and risk of anemia remained significant, even after considering the dilutive effect of milk consumption on the density of iron in the diet, thus indicating a possible inhibitor effect of milk on the absorption of the iron present in the other foods ingested by the child. CONCLUSIONS: The relative participation of cow's milk in the child's diet showed a significant positive association with risk of anemia in children between ages six and 60 months, regardless of the density of iron in the diet.

    with risk of exposure to rabies virus infection still presents some cases of undesirable post treatment reactions. The knowledge resulting from the regular analysis of the epidemiological features associated with these practices would minimize the occurrence of these troubles. METHODS: The records of the treatment of 8,758 human anti-rabies cases performed in Osasco City, S. Paulo, Brazil between 1984 and 1994 with Fuenzalida & Palacios vaccine and/or anti-rabies serum produced in equines were analysed by Epi Info program. RESULTS: It was found that the higher risk of exposure was for male children of from five to nine years of age. The most frequent scene of aggression was the victim's own house. Dogs were responsible for most of the accidents (62.8%; the majority of dogs and cats involved had not been immunized against rabies (51.0% of dogs and 73.2% of cats. Most people aged nine or under were attacked in the head (36.6%, followed by the upper limbs (35.1%; above this age the part of the body most frequently hurt was the upper (45.8% and lower limbs (43.7%; 26.5% of patients had already been vaccinated against rabies at least once in their lifetime; 90.7% of them sought medical care within five days, anti-rabies treatment was prescribed for 41.9% of them. CONCLUSIONS: Post vaccinal reactions were observed in 0.25% of the patients 0.3% of which were of neurological; 80.1% of the dogs and 58.4% of the cats involved coere kept under observation. The months of March, July, August and September presented the highest aggression rates.

    Indicators are applied faster and at lower costs than conventional surveys, providing quick and efficient responses that can facilitate protected areas management. Our aim was to select indicators from vegetation to monitor protected areas. For this purpose, we analyzed understory and quantified lianas and tree ferns in protected and non-protected areas, in order to find indicator species. Our study areas are located in Vale do Ribeira, southeastern São Paulo state, Brazil. One of the areas is under two protection categories (IUCN's categories II and V), and the other is a privately owned farm. Lianas with large diameters (> 13 cm) and tree ferns with great heights (> 19 m) were considered indicators of undisturbed areas (protected areas) because their growth is directly related to forest successional stage. Indicator species within the protected area were shade tolerant species, such as Bathysa australis (A.St.-Hil.) K.Schum., whereas outside the protected area were pioneer species, such as Pera glabrata (Schott) Poepp. ex Baill. e Nectandra oppositifolia Ness. All of the suggested indicators can be used in management actions, especially in protected areas, to guarantee forest maintenance and ensure fulfillment of the conservation objectives of these areas.

    Full Text Available Diplectrum formosum (the sand perch, Diplectrum radiale (the aquavina, Epinephelus marginatus (the dusky grouper and Mycteroperca acutirostris (the comb grouper are four sympatric serranid of remarkable ecological and commercial importance. This study investigated the feeding of these four species in the São Sebastião Channel, São Paulo State (southeastern Brazil, comparing their diet, habitat utilization and morphological features related to foraging. These four serranids are opportunistic visual predators that use a total of nine different tactics to capture their preys, feed mostly on crustaceans during the day and twilight, and keep stationary and quiescent at night. The ecomorphological study was conducted to test its predictive value to infer lifestyles. It was verified that such analysis should be used carefully and must be complemented by field observations. Although morphologically and behaviorally very similar, D. formosum and D. radiale showed different preferences to the substratum type used by large individuals, which are exclusively sit-and-wait predators. On the other hand, E. marginatus displayed more sedentary habits than M. acutirostris, the most versatile predator from the studied species. The studied species of Diplectrum and E. marginatus can be regarded as benthic serranids, while M. acutirostris could be viewed as a nektobenthic species.

    Full Text Available The main objective of this study was to examine the natural history and the ecology of the species that constitute a snake assemblage in the Atlantic Rainforest, at Núcleo Picinguaba, Parque Estadual da Serra do Mar, located on the northern coast of the state of São Paulo, southeastern Brazil. The main aspects studied were: richness, relative abundance, daily and seasonal activity, and substrate use. We also provide additional information on natural history of the snakes. A total of 282 snakes, distributed over 24 species, belonging to 16 genera and four families, has been found within the area of the Núcleo Picinguaba. Species sampled more frequently were Bothrops jararaca and B. jararacussu. The methods that yielded the best results were time constrained search and opportunistic encounters. Among the abiotic factors analyzed, minimum temperature, followed by the mean temperature and the rainfall are apparently the most important in determining snake abundance. Most species presented a diet concentrated on one prey category or restricted to a few kinds of food items. The large number of species that feed on frogs points out the importance of this kind of prey as an important food resource for snakes in the Atlantic Rainforest. Our results indicate that the structure of the Picinguaba snake assemblage reflects mainly the phylogenetic constraints of each of its lineages.O principal objetivo deste estudo foi obter informações sobre a história natural e a ecologia das espécies que compõem uma taxocenoses de serpentes da Mata Atlântica, no Núcleo Picinguaba do Parque Estadual da Serra do Mar, localizado no litoral norte do estado no Estado de São Paulo, sudeste do Brasil. Os principais aspectos estudados foram: riqueza, abundância relativa de espécies, padrões de atividade diária e sazonal, utilização do ambiente e dieta.

    To assess the validity and reproducibility of a food frequency questionnaire developed for estimating the food consumption of adults in São Paulo, Brazil, based population study. A sample of individuals aged above 20 years, of both genders, living in São Paulo, was used for the validation study (n = 77) and reproducibility study (n = 74) of the food frequency questionnaire. To verify the validity and reproducibility of energy and 19 nutrients were applied two food frequency questionnaires (60 items) and three 24-hour dietary recalls (24HR - reference method). The validity was verified by Spearman correlation coefficient (crude and de-attenuated) and weighted Kappa, and reproducibility by intraclass correlation coefficients and weighted kappa. In analyzes of validity de-attenuated correlation coefficients ranged from 0.21 (carbohydrate) to 0.74 (energy), and weighted kappa exceeded 0.40 for 30% of the nutrients. Polyunsaturated fat and folate did not show significant correlation and weighted kappa. In reproducibility correlation coefficients ranged from 0.36 (polyunsaturated fat) to 0.69 (calcium), and weighted kappa exceeded 0.40 for 80% of the nutrients. The food frequency questionnaire analyzed has good validity and reproducibility for estimating the food consumption of adults in São Paulo compared to the reference method, so it is an appropriate instrument to be used in epidemiological studies on similar populations. Estimates of polyunsaturated fat and folate should be interpreted with caution.

  2. Gastrointestinal parasites of maned wolf (Chrysocyon brachyurus, Illiger 1815 in a suburban area in southeastern Brazil

    Directory of Open Access Journals (Sweden)

    RL Massara

    Full Text Available AbstractWe examined 42 maned wolf scats in an unprotected and disturbed area of Cerrado in southeastern Brazil. We identified six helminth endoparasite taxa, being Phylum Acantocephala and Family Trichuridae the most prevalent. The high prevalence of the Family Ancylostomatidae indicates a possible transmission via domestic dogs, which are abundant in the study area. Nevertheless, our results indicate that the endoparasite species found are not different from those observed in protected or least disturbed areas, suggesting a high resilience of maned wolf and their parasites to human impacts, or a common scenario of disease transmission from domestic dogs to wild canid whether in protected or unprotected areas of southeastern Brazil.

    Bats are considered to play a significant role in the epidemiology of histoplasmosis, worldwide. We investigated the occurrence of H. capsulatum in lung samples from 89 bats, from urban areas in Southeastern Brazil, using nested PCR based on ribosomal DNA. Fungal DNA was detected in 31/89 samples (34.8%), of which 13/31 were Molossids (41.9%), 4/31 Eumops spp. (12.9%), 2/31 Artibeus lituratus (6.5%), and 12/31 others (38.7%). This is the first report of natural infection by H. capsulatum in A. lituratus in Southeastern Brazil, which reinforces the importance of these synanthropic animals in the epidemiology of histoplasmosis in urban areas. © The Author(s) 2017.

    Full Text Available Philopotamidae is a large caddisfly family with 20 extant genera comprising about 1 000 described species worldwide. Alterosa contains 22 described species distributed in South and Southeastern Brazil. Adults of the genus are very similar in general structure, but are remarkable for their wide variation in male genitalic morphology. The specimens were collected with Pennsylvania light traps and preserved in 80% ethanol. Alterosa nessimiani sp. nov. is described and figured from male specimens collected in streams of Rio de Janeiro state, Southeastern Brazil. The new species is closely related to A. jordaensis Blahnik 2005, from which it can be distinguished by the presence of two spines on the intermediate appendages and by the shape of tergum X. Rev.

    GENERAL OBJECTIVE: to analyse the exercise of essential competencies for midwifery care by nurses and/or midwives in the public health system of São Paulo (eastern zone), Brazil. to develop a profile of the public health institutions and of the nurses and/or midwives who care for women before, during and following childbirth; to identify the activities performed in providing such care, as well as their frequency; and to specify the possible obstacles or difficulties encountered by them when exercising their competencies. a descriptive and exploratory research design, using a quantitative approach. the study was conducted in all public health services of São Paulo (eastern zone), Brazil, namely 59 basic health-care units and six hospitals, during the period of October 2006-December 2007. the study population consisted of 272 nurses and/or midwives who provide care for pregnant women and newborns at the primary health-care units and maternity hospitals of the public health system. Participants comprised 100% of hospital nurse coordinators (n=6), 61% of hospital maternity nursing and/or midwifery staff (n=62) and 64% (n=204) of nursing and/or midwifery staff working at primary health-care units. the data collection was based on a single form given to the coordinators and two questionnaires, one handed out to antenatal and postnatal nursing and/or midwifery staff and another handed out to labour and birth nursing and/or midwifery staff. The results showed that nurses and/or midwives providing care for women during pregnancy, labour, birth and the postnatal period did not put the essential competencies for midwifery care into practice, because they encountered institutional barriers and personal resistance, and lacked protocols based on best practice and on the exercise of essential competencies needed for effective midwifery care. the model of care in the public health services of São Paulo (eastern zone) is based much more on hierarchical positions than on

    Full Text Available Objective: To evaluate eating disorders risk behaviors and unhealthy weight control practices among adolescents who consider themselves as vegetarians and those who are omnivorous.Material and Methods: A cross-sectional study was conducted in 12 technical schools in the city of São Paulo, Brazil. The sample included 1167 adolescents (51% female, aged 14 to 19 (mean age, 16. Adolescents stated whether they  were currently vegetarian, and the sample was dichotomized as vegetarian and non-vegetarian. The two groups were compared as regards weight status, eating disorder risk behavior, unhealthy weight control methods and the perception of healthy eating.Results: About 4% of the sample was currently vegetarian, most of them female (70.8%, and females were 2.89 times more likely to be vegetarian than males. No relationship was found between the vegetarian status and unhealthy weight control behavior; however the vegetarian group considered their diet to be healthier than the non-vegetarian group (P=.04.Conclusions: The frequency of vegetarianism, as well the frequency of eating disorder risk behaviors had no association in this adolescent sample from São Paulo, Brazil.

    There is worldwide recognition that the burden of noncommunicable diseases (NCDs) and obesity-related health problems is rapidly increasing in low- and middle-income countries. Environmental determinants of obesity are likely to differ between countries, particularly in those undergoing rapid socioeconomic and nutrition transitions such as Brazil. This study aims to describe some built environment and local food environment variables and to explore their association with the overweight rate and diet and physical activity area-level aggregated indicators of adults living in the city of Sao Paulo, the largest city in Brazil. This formative study includes an ecological analysis of environmental factors associated with overweight across 31 submunicipalities of the city of Sao Paulo using statistical and spatial analyses. Average prevalence of overweight was 41.69% (95% confidence interval 38.74, 44.64), ranging from 27.14% to 60.75% across the submunicipalities. There was a wide geographical variation of both individual diet and physical activity, and indicators of food and built environments, favoring wealthier areas. After controlling for area socioeconomic status, there was a positive correlation between regular fruits and vegetables (FV) intake and density of FV specialized food markets (r = 0.497; p fast-food restaurant density and overweight prevalence was found. A negative association between overweight prevalence and density of parks and public sport facilities was seen (r = -0.527; p food access and health inequalities.

    This study examined compulsive sexual behavior (CSB) and psychopathology in a treatment-seeking sample of men in São Paulo, Brazil. Eighty-six men (26% gay, 17% bisexual, 57% heterosexual) who met diagnostic criteria for excessive sexual drive and sexual addiction completed assessments consisting of the Mini International Neuropsychiatric Interview, a structured clinical interview for DSM-IV Axis I Disorders-Clinical Version (segment for Impulse Control Disorder), Sexual Compulsivity Scale (SCS), and questions about problematic CSB. The average SCS score for our sample was above the cut-off score reported in other studies, and 72% of the sample presented at least one Axis I psychiatric diagnosis. There were no differences among gay, bisexual, and heterosexual men on SCS scores and psychiatric conditions, but gay and bisexual men were more likely than heterosexual men to report casual sex and sex with multiple casual partners as problematic behaviors. SCS scores were associated with psychiatric co-morbidities, mood disorder, and suicide risk, but diagnosis of a mood disorder predicted higher SCS scores in a regression analysis. The study provides important data on the mental health needs of men with CSB in São Paulo, Brazil. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

    Full Text Available An increased incidence of nosocomial and community-acquired infections caused by methicillin-resistant Staphylococcus aureus (MRSA has been observed worldwide. The molecular characterization of MRSA has played an important role in demonstrating the existence of internationally disseminated clones. The use of molecular biology methods in the surveillance programs has enabled the tracking of MRSA spread within and among hospitals. These data are useful to alert nosocomial infection control programs about the potential introduction of these epidemic clones in their areas. Four MRSA blood culture isolates from patients hospitalized at two hospitals in the city of São Paulo, Brazil, were analyzed; one of them was community acquired. The isolates were characterized as SCCmec, mecA and PVL by PCR, pulsed-field gel electrophoresis (PFGE profile and molecular sequence typing (MLST genotyping. The isolates presented type IV SCCmec, and none proved to be positive for PVL. The isolates showed a PFGE profile similar to the pediatric clone. MLST genotyping demonstrated that the isolates belonged to clonal complex 5 (CC5, showing a new yqiL allele gene, resulting in a new sequence typing (ST (1176. Our results showed that strains of MRSA carrying a new ST are emerging in community and nosocomial infections, including bacteremia, in São Paulo, Brazil.

    MO. Segura

    Full Text Available Inventories provide information on the state of biodiversity at a site or for a geographic region. Species inventories are the basis for systematic study and critical to ecology, biogeography and identification of biological indicators and key species. They also provide key information for assessments of environmental change, for natural resource conservation or recovery of degraded ecosystems. Thus, inventories play a key role in planning strategies for conservation and sustainable use. This study aimed to inventory the fauna of water beetles, larvae and adults, in two mountainous regions in the state of São Paulo, in Serra da Mantiqueira (Parque Estadual de Campos do Jordão and Pindamonhangaba region and in Serra do Mar (Santa Virgínia and Picinguaba Divisions as well as to generate information about the habitats used by the different genera recorded. Specimens were collected in lotic and lentic systems, between the years 2005 to 2010. In total 14,492 specimens were collected and 16 families and 50 genera of Coleoptera were identified. This study in mountainous regions showed a significant portion of the faunal composition of South America and the state of São Paulo. The composition of the fauna, in terms of richness and abundance by family, indicated the predominance of Elmidae, followed by Hydrophilidae and Dytiscidae. Despite the diversity found, the results of estimated richness indicated the need for additional sampling effort for both regions, since the curves of estimated richness did not reach an asymptote, suggesting that new species can be found in future surveys.

    Full Text Available Epidemiological research suggests that air pollution may cause chronic diseases, as well as exacerbation of related pathologies such as cardiovascular and respiratory morbidity and mortality. This study evaluates air pollution scenarios considering a Health Impact Assessment approach in São Paulo, Brazil. We have analyzed abatement scenarios of Particulate Matter (PM with an aerodynamic diameter <10 μm (PM10, <2.5 μm (PM2.5 and ozone concentrations and the health effects on respiratory and cardiovascular morbidity and mortality in the period from 2009 to 2011 through the APHEKOM tool, as well as the associated health costs. Considering World Health Organization (WHO standards of PM2.5 (10 μg/m3, São Paulo would avoid more than 5012 premature deaths (equivalent to 266,486 life years’ gain and save US$15.1 billion annually. If São Paulo could even diminish the mean of PM2.5 by 5 μg/m3, nearly 1724 deaths would be avoided, resulting in a gain of US$ 4.96 billion annually. Reduced levels of PM10, PM2.5 and ozone could save lives and an impressive amount of money in a country where economic resources are scarce. Moreover, the reduced levels of air pollution would also lower the demand for hospital care, since hospitalizations would diminish. In this sense, Brazil should urgently adopt WHO air pollution standards in order to improve the quality of life of its population.

    Advances in geospatial technologies have recognized the role of geographic distance as a barrier to healthcare accessibility. Frequent transportation is supposed to buffer issues with distance, while infrequent services impede the uptake of care. The role of public transportation on the accessibility of health care-including oral health care-is not well elucidated in the context of megacities, such as the municipality of São Paulo, Brazil. This study aimed to compare the supply of public transportation to primary dental clinics and the population between advantaged and disadvantaged areas in São Paulo city. A total of 4101 primary dental clinics in São Paulo city were identified and geocoded. Geographic coordinates were also retrieved for the 19 242 bus stops, 56 commuter rail stations and 64 rapid transit stations. Clinic locations and transport points were integrated with the city's 19 128 constituent census tracts-each containing sociodemographic data on the 11 252 204 residents-using Geographic Information Systems (GIS). Almost all clinics were located within 0.5 km of public transportation. Half of all clinics were within 0.5 km of high-frequency transport points, and three-quarters were within 1 km. Likewise, 99% of the population resided within 0.5 km of any public transportation. However, only 22% were within 0.5 km of high-frequency options, and half were within 1 km. Those within 0.5 km of high-frequency points had higher average monthly household incomes and lower illiteracy rates, with lower proportions of children and ethnic minorities, and higher proportions of older people. Clinics and populations in sociodemographically disadvantaged tracts have poorer public transportation links in São Paulo city. © 2018 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

  6. Low water quality in tropical fishponds in southeastern Brazil

    SIMONE M. COSTA

    2014-09-01

    Full Text Available Expansion of aquaculture around the world has heavily impacted the environment. Because fertilizers are needed to raise fish, one of the main impacts is eutrophication, which lowers water quality and increases the frequency of algal blooms, mostly cyanobacteria. To evaluate whether the water quality in 30 fishponds in southeastern Brazilian met the requirements of Brazilian legislation, we analyzed biotic and abiotic water conditions. We expected that the high nutrient levels due to fertilization would cause low water quality. We also analyzed cyanotoxins in seston and fish muscle in some systems where cyanobacteria were dominant. The fishponds ranged from eutrophic and hypereutrophic with high phytoplankton biomass. Although cyanobacteria were dominant in most of the systems, cyanotoxins occurred in low concentrations, possibly because only two of the 12 dominant species were potential producers of microcystins. The high phosphorus concentrations caused the low water quality by increasing cyanobacteria, chlorophyll-a, turbidity, and thermotolerant coliforms, and by depleting dissolved oxygen. We found that all the 30 systems were inappropriate for fish culture, according to Brazilian legislation, based on at least one of the parameters measured. Furthermore, there was not any single system in the water-quality thresholds, according to the Brazilian legislation, to grow fish. Our findings indicate the need for better management to minimize the impacts of eutrophication in fishponds, in addition to a rigorous control to guarantee good food.

To characterize the genetic diversity of Mycobacterium tuberculosis in the population of this city, the genotyping techniques of spoligotyping and MIRU were applied to 93 isolates collected in two consecutive years from 93 different tuberculosis patients residing in São Paulo city and attending the Clemente Ferreira Institute (the reference clinic for the treatment of tuberculosis). Spoligotyping generated 53 different spoligotype patterns. Fifty-one isolates (54.8%) were grouped into 13 spoligotyping clusters. Seventy- two strains (77.4%) showed spoligotypes described in the international databases (SpolDB4, SITVIT), and 21 (22.6%) showed unidentified patterns. The most frequent spoligotype families were Latin American Mediterranean (LAM) (26 isolates), followed by the T family (24 isolates) and Haarlem (H) (11 isolates), which together accounted for 65.4% of all the isolates. These three families represent the major genotypes found in Africa, Central America, South America and Europe. Six Spoligo-International-types (designated SITs by the database) comprised 51.8% (37/72) of all the identified spoligotypes (SIT53, SIT50, SIT42, SIT60, SIT17 and SIT1). Other SITs found in this study indicated the great genetic diversity of M. tuberculosis, reflecting the remarkable ethnic diversity of São Paulo city inhabitants. The MIRU technique was more discriminatory and did not identify any genetic clusters with 100% similarity among the 93 isolates. The allelic analysis showed that MIRU loci 26, 40, 23 and 10 were the most discriminatory. When MIRU and spoligotyping techniques were combined, all isolates grouped in the 13 spoligotyping clusters were separated. Our data indicated the genomic stability of over 50% of spoligotypes identified in São Paulo and the great genetic diversity of M. tuberculosis isolates in the remaining

    American visceral leishmaniasis (AVL) is an emerging disease in the state of São Paulo, Brazil. Its geographical expansion and the increase in the number of human cases has been linked to dispersion of Lutzomyia longipalpis into urban areas. To produce more accurate risk maps we investigated the geographic distribution and routes of expansion of the disease as well as chemotype populations of the vector. A database, containing the annual records of municipalities which had notified human and canine AVL cases as well as the presence of the vector, was compiled. The chemotypes of L. longipalpis populations from municipalities in different regions of São Paulo State were determined by Coupled Gas Chromatography - Mass Spectrometry. From 1997 to June 2014, L. longipalpis has been reported in 166 municipalities, 148 of them in the Western region. A total of 106 municipalities were identified with transmission and 99 were located in the Western region, where all 2,204 autochthonous human cases occurred. Both the vector and the occurrence of human cases have expanded in a South-easterly direction, from the Western to central region, and from there, a further expansion to the North and the South. The (S)-9-methylgermacrene-B population of L. longipalpis is widely distributed in the Western region and the cembrene-1 population is restricted to the Eastern region. The maps in the present study show that there are two distinct epidemiological patterns of AVL in São Paulo State and that the expansion of human and canine AVL cases through the Western region has followed the same dispersion route of only one of the two species of the L. longipalpis complex, (S)-9-methylgermacrene-B. Entomological vigilance based on the routes of dispersion and identification of the chemotype population could be used to identify at-risk areas and consequently define the priorities for control measures.

    Full Text Available Termites are key components of soil fauna, playing an essential role in organic matter decomposition and nutrient cycling. However, they can cause significant economic losses in commercial plantations, such as sugar cane. Therefore, the correct identification of termite species is critical for pest control. Here, we evaluated the species richness, abundance and functional groups of termites in sugarcane plantations in 53 cities throughout the state of São Paulo, southeastern Brazil. We also analyzed the influence of macroclimatic variables on termite species distribution and functional groups. We found 22 taxa of two families, of which the most frequent species were Termitidae (96.51%. Within this family, Apicotermitinae had the highest frequency of occurrence (37.12%, followed by Termitinae (30.57%, Syntermitinae (27.95%, and Nasutitermitinae (0.8 %. The other family, Rhinotermitidae, had the lowest frequency (3.5%, being represented only by Heterotermes sulcatus Mathews. We classified Neocapritermes opacus Hagen (29.26%, Apicotermitinae sp.2 (24.89%, Cornitermes cumulans Kollar (13.10%, and Apicotermitinae sp.1 (6.99% as common taxa. The remaining 18 species were classified as rare. The most common functional group was humus-feeders (37%, followed by wood-feeders (34%, grass-litter feeders (25%, and intermediate feeders (4%. Climate influenced the distribution of common species, humus-feeders and grass-litter feeders. Regarding the pest status of termites in sugar cane plantations, we suggest that the exasperated use of pesticide in the last decades has reduced the abundance of species considered pests (e.g. Heterotermes and reinforce the importance of ecological approaches for determining the best pest control methods.

    Following reports of two autochthonous cases of sylvatic yellow fever in the State of São Paulo, Brazil, in 2000, entomological surveys were conducted with the objective of verifying the occurrence of vector species in forest environments close to or associated with riparian areas located in the western and northwestern regions of the State. Culicidae were captured in 39 sites distributed in four regions. Haemagogus leucocelaenus and Aedes albopictus were the most abundant species and were captured in all the regions studied. H. leucocelaenus was the most abundant species in the municipalities of Santa Albertina and Ouroeste, where the two cases of sylvatic yellow fever had been reported. Mosquitoes from the janthinomys/capricornii group were only found at eight sites in the São José do Rio Preto region, while Sabethes chloropterus was found at one site in Ribeirão Preto. H. leucocelaenus showed its capacity to adapt to a secondary and degraded environment. Our results indicate a wide receptive area for yellow fever transmission in the State of São Paulo, with particular emphasis on the possibility of H. leucocelaenus being involved in the maintenance of this sylvatic focus of the disease.

    BACKGROUND Acne is a common disease in adolescents, but there are no epidemiological data for acne in Brazil. OBJECTIVES To estimate the prevalence and degree of acne in adolescents from Sao Paulo and study socio-demographic factors, family history and lifestyle, associated with the disease. METHODS Cross-sectional study with 452 adolescents aged between 10 and 17 (mean=13.3 years), students from elementary and high school, examined by 3 independent evaluators. RESULTS 62.4% were female, 85.8% white and 6.4% were aged 14. The prevalence was 96.0% and increased with age - all students over 14 had acne. The most prevalent form of acne was comedonal (61.1%), followed by mild (30.6%) and moderate (7.6%) papular-pustular, which affected mostly the face (97.5%). About half of the adolescents reported family history for acne in mother or father, and 20.6% reported previous treatment for acne. There was a higher chance of presenting non-comedonal acne with increased age (pacne in adolescents varies widely due to the clinical features and diagnostic methods used. Adolescents whose brothers/sisters had acne (OR=1.7-p=0.027) and those over 13 (OR=8.3-pacne. CONCLUSION This study showed high prevalence of acne in adolescents from Sao Paulo, predominantly the comedonal form on the face, with a higher chance of presenting non-comedonal acne with increased age.

    This study evaluated the prevalence of the populations and serotypes of Listeria monocytogenes in 552 refrigerated samples of ground beef, chicken leg, hot dog, and pork sausage collected in supermarkets in the city of Sao Paulo, SP, Brazil, between May 2008 and July 2009. The supermarkets were selected after stratification by geographical region and by random draw. Tests for presence and enumeration of L. monocytogenes were based on ISO 11290-1:1996/Amd.1:2004 and ISO 11290-2:1998 methods, respectively. Listeria spp. were detected in 469 (85.0%) of the studied meat products. The most frequently isolated species was L. innocua (64.1%), followed by L. monocytogenes (48.7%), L. welshimeri (13.4%), L. seeligeri (7.1%), L. ivanovii (0.2%), and L. grayi subspecies murrayi (0.2%). L. monocytogenes was detected in 269 (48.7%) samples, with highest prevalence in ground beef (59.4%) followed by chicken legs (58.0%), pork sausages (39.8%), and hot dogs (37.7%). The populations were Prevalence of serotypes varied according to the type of meat product. These data are relevant for estimating the risks of listeriosis associated with consumption of meat products in Sao Paulo, and for establishing science-based intervention strategies aimed at reducing these risks, especially for pregnant women and immunocompromised individuals.

    Black carbon (BC) is a major absorber of solar radiation, and its impact on the radiative balance is therefore considered important. Fossil fuel combustion processes and biomass burning result in the emission of BC. Black carbon is being monitored since 2014 with a Multi-Angle Absorption Photometer-MAAP (5012; Thermo Scientific) in the East Zone of São Paulo, Brazil. São Paulo Metropolitan Area with more than 19 million inhabitants, 7 million vehicles, has high concentrations of air pollutants, especially in the winter. Vehicles can be considered the principal source of particles emitted to the atmosphere. Concentration of the pollutant had an average of 1.95 ug.m-3 ± 2.06 and a maximum value of 19.93 ug.m-3. These large variations were due to meteorological effects and to the influence of anthropogenic activities, since samples were collected close to important highways. Winds coming from the East part predominate. Higher concentrations were found in the winter months (June, July and August). Optical data from AERONET (Aerosol Optical Depth-AOD 550 nm and Angstrom Exponent 440-675 nm) were related to BC concentrations for the period from August, 2016. Average values of AOD at 500 nm and Angstrom Parameter (440-675nm) were 0.16±0.11 and 1.44±0.23, respectively. Higher BC concentrations were related to lower Angstrom values.

    Full Text Available Leptospirosis is a waterborne disease and, therefore, stands out for the possibility of environmental contamination, the cross transmission between domestic and wild animals and humans. Opossum species are important reservoirs of this disease making them potential pathogen spreaders. Aiming to verify the presence of Leptospira spp. and the antibodies against Leptospira spp. in the Campus of São Paulo State University, in Jaboticabal, São Paulo, Brazil, freeliving wild life opossum (Didelphis albiventris were captured for blood and urine sampling. Serological analysis was performed Microscopic Agglutination Test (MAT. Aliquots of urine were seeded in media Ellinghausen-McCullough- Johnson-Harris (EMJH and Fletcher without antibiotics. The samples in which there was growth of leptospires were forwarded to the Leptospirosis Laboratory of the Institute of Pathobiology in the National Institute of Agricultural Technology, Buenos Aires, Argentina and were genotyped using Multiple Locus Variable number tandem repeat Analysis (MLVA. Of the 15 analyzed animals, nine (60.0% were reactant to Patoc serovar. The pathogenic specie Leptospira borgpetersenii was isolated and identified in three Didelphis albiventris. The isolation findings of pathogenic specie Leptopsira borgpetersenii in the urine culture of three Didelphis albiventris in a university campus are a major discovery in the area of preventive veterinary medicine and public health and open a discussion about the important role of free-living wild animals as reservoirs of this agent to domestic animals and humans, a condition that serves as a warning for the improvement of health practices.

    Epiphytic bromeliad Tillandsia usneoides was used as a biomonitor of metal atmospheric pollution in the city of Sao Paulo, Brazil. The samples were collected from an unpolluted area and were exposed for 8 weeks in 10 sites of the city and in a control site. The data obtained showed that the control site presented lower concentration for most elements analyzed and the highest concentrations of Na, Cl, Br, K. The highest concentrations of Zn, Cu and V were observed in stations submitted to industrial and vehicular sources. The results obtained for rare earth elements, Al, Fe, Mg, Mn, Rb and Sc indicate mineral dust origin. The elements Ba, As and Sb presented higher values in stations near streets with heavy traffic.

    This article presents the results of a case study aimed at identifying challenges for the delivery of primary health care in a health district in the city of São Paulo, Brazil, considering comprehensiveness as a central device for organizing work at this level of care. Five units in the district's primary care network were studied. We collected the data by observing work routines and flows, conducting interviews with managers and health professionals from different backgrounds, and through focus groups with family health teams. The analysis shows a mismatch between users' characteristics and their presumed needs and the heterogeneity of the health professionals' perceptions concerning their work. Lack of staff and time and difficulties with referrals were the main problems identified by interviewees.

    The authors report on the development of a work accident monitoring system in Piracicaba, São Paulo State, Brazil, with the following characteristics: information feeding the system is obtained in real time directly from accident treatment centers; the system has universal monitoring, covering all work-related accidents in Piracicaba, regardless of the nature of the worker's employment conditions, place of work, or place of residence; health surveillance and promotion of health initiatives are triggered by identification of sentinel events; spatial distribution analysis of work-related accidents is a basic tool in designing accident awareness strategies and accident prevention policies. The system was implemented in November 2003 and by October 2004 had identified 5,320 work-related accidents, or a 3.8% annual proportional incidence of work-related accidents in the municipal area. We illustrate spatial analysis of registered work-related accidents and present a detailed investigation of one example of a serious accident.

    Full Text Available This work investigated the effect of repeated applications on enhanced degradation of metalaxyl in two different agricultural soils used for cultivation of orange and lemon from Casa Branca and Itapetininga districts of São Paulo State, Brazil. Soil samples were collected from areas repeatedly treated with commercial ridomil 50GR for six successive years, and from other areas never exposed to this fungicide. At the laboratory, soil samples received a 14C-metalaxyl solution and its degradation was studied through radiometric techniques to measure biomineralization and recovery of extractable- and soil-bound products. Enhanced degradation was verified only in one soil, although partial degradation and mineralization of the fungicide were detected in both soils. The different rates and patterns of metalaxyl degradation in the soils were probably due to their different physical, chemical, and biological characteristics.

    Radiation therapy services provide essential therapeutic procedures for cancer, one of the main causes of population morbidity and mortality. Despite their importance in the health system and their potential risks due to the use of ionizing radiation, there are few studies on such services. We evaluated compliance with technical standards for radiological protection in radiation therapy services in Sao Paulo State, Brazil. Forty-nine services were studied in 2000 through interviews with technical staff. Typologies of performance profiles focusing on structure and process variables were constructed and services compared. Important differences were observed in the services' positions in the health care system, level of complexity, and geographic distribution, with better average performance in structural conditions but very inadequate performance in patient protection, indicating the need for more effective health surveillance.

    2002-09-01

    We study the effects of various air-pollution variables on the daily death counts for people over 65 years in São Paulo, Brazil, from 1991 to 1993, controlling for meteorological variables. We use a state space model where the air-pollution variables enter via the latent process, and the meteorological variables via the observation equation. The latent process represents the potential mortality due to air pollution, and is estimated by Kalman filter techniques. The effect of air pollution on mortality is found to be a function of the variation in the sulphur dioxide level for the previous 3 days, whereas the other air-pollution variables (total suspended particulates, nitrogen dioxide, carbon monoxide, ozone) are not significant when sulphur dioxide is in the equation. There are significant effects of humidity and up to lag 3 of temperature, and a significant seasonal variation.

    To measure added sugars intake among adolescents and describe its demographic, socioeconomic, and nutritional status determinants. The study was conducted based on a household survey carried out between March and December 2003. Food intake was assessed through 24-hour food recalls, and an adjustment approach was applied using external variance estimates derived from 195 adolescents of the same age in 2007. Population-based cross-sectional study, city of São Paulo, Brazil. Seven hundred and ninety-three male (n = 410) and female (n = 383) adolescents aged 10-19 years. MEASURE OF OUTCOME: Foods with greater contributions toward the added sugars intake were identified. Multiple linear regression analysis was performed, with calories from added sugars as the dependent continuous variable and the remaining factors (socioeconomic, demographic, lifestyle, household condition, and food intake) as independent variables. The average contribution of added sugars to total energy value was 12.28% (95% confidence interval [CI]: 11.87-12.70) with no statistically significant sex difference (p > 0.05). Soft drinks were a major source of added sugars among the adolescents (34.2% among males and 32.0% among females), followed by sugars (sucrose and honey) and chocolate powder (around 11%). In the multiple linear regression analysis, the head of household's education level and calories from protein, fats, and carbohydrates other than sugars had an independent effect on added sugars intake. This study showed that the percentage contribution of added sugars to energy intake among adolescents in the city of São Paulo, Brazil, was above the current recommended levels. Socioeconomic condition (represented by the head of the household's education level) and macronutrient intake were shown to be determinants of sugars intake.

    Full Text Available Although studies show that portion size affects energy intake, few have demonstrated a link between portion size and weight status, especially in free-living populations. The objective of the present study was to assess the relationship between food portion sizes and overweight in a representative population of adults of São Paulo, Brazil.Cross-sectional population-based study with 1005 adults from São Paulo, Brazil. Dietary data were obtained from two 24-hour recalls. Reported foods were classified into groups and energy contribution, prevalence of consumers and portion sizes were calculated. Individuals were classified according to BMI in with and without overweight. Logistic regression models were used to evaluate the association between food portion sizes and being overweight.The most consumed food groups were: beans, breads/rolls, coffee/tea, milk, rice, and sugar. Rice, red meat, breads/rolls, and white meat were the groups with the highest percentage of contribution to total energy intake. Butter/margarine, toasts/biscuits, sugar, and cakes were the groups with the highest energy density. After adjustment for confounding variables, overweight was associated with larger portions of pizza (OR = 1.052; p = 0.048, red meat (OR = 1.025; p = 0.043, rice (OR = 1.033; p<0.001, salted snacks (OR = 1.078; p = 0.022, and soft drinks (OR = 1.016; p = 0.007.Larger portions of few food groups with different energy densities were associated with being overweight, suggesting that overweight may be related to the consumption of larger portion sizes of a series of food groups, not a food group alone. Additionally, we highlight the importance of considering underreporting as a confounding factor in these associations.

    Full Text Available This study describes the distribution of fish eggs and larvae along the southeastern and southern Brazilian coast. Plankton samples were collected at 85 stations using a Bongo net, and water salinity and temperature were profiled with a CTD. Results showed that fish eggs and larvae, and zooplankton biovolume were distributed in coastal waters with mean temperature of 23ºC and salinity between 33 and 34. The largest egg abundance occurred along Iguape (24º'S with a partial overlap with zooplankton biovolume and fish larvae were most abundant near shore close to Santos (24ºS. These protected coastal waters presented a surface layer with lower salinity and higher temperatures, while the bottom layer had cooler water. Ichthyoplankton abundance was low off Cabo Frio (22º'S, while a maximum in fish eggs occurred around Cabo Santa Marta Grande (28ºS.A abundância de ovos e larvas de peixes serve como um indicador do tamanho do estoque desovante, e a variabilidade nestes parâmetros está associada a flutuações no recrutamento de recursos pesqueiros. No sul e sudeste do Brasil a distribuição do ictioplâncton é influenciada pela dinâmica da Confluência Subtropical, pelo aporte de água doce e pela ação do vento na camada superficial do oceano. Este trabalho tem como objetivo descrever a distribuição de ovos e larvas de peixes ao longo da área compreendida entre Cabo Frio (22º'S e o Cabo de Santa Marta Grande (28ºS, entre 15/11 e 05/12/95. Em 85 estações foram coletadas amostras de plâncton com uma rede Bongo de 60cm de diâmetro e 330m m de malha, dotada de fluxômetro e arrastada obliquamente. Salinidade e temperatura foram obtidas em cada estação com um CTD. O maior número de ovos e larvas de peixes e biovolume de zooplâncton foram encontrados em áreas distintas na região costeira, em temperaturas entre 23 e 24ºC e salinidades entre 33 e 34.

    Full Text Available Embora o aborto provocado no Brasil seja importante problema de saúde, é difícil conhecer a exata medida de sua ocorrência, em função da ilegalidade dessa prática. Com a disponibilidade das informações sobre as hospitalizações pelo Ministério da Saúde, tornou-se possível conhecer, ainda que de forma incompleta, o quadro dos abortos atendidos na rede hospitalar do SUS. O objetivo do estudo foi conhecer as 53.861 internações com diagnóstico de aborto entre mulheres de 10 a 49 anos na rede hospitalar conveniada com o SUS no Estado de São Paulo no ano de 1995, segundo o tipo do aborto, idade e local de residência. As internações de mulheres em idade reprodutiva no Estado de São Paulo, em 1995, representaram 37,8% do total das hospitalizações pagas pelo SUS, sendo que dessas 59,6% foram por questões ligadas à gravidez, parto e puerpério, dentre as quais os abortos representam cerca de 10%. Sua distribuição nas regiões da Grande São Paulo e Interior do Estado mostra que é maior a proporção aborto/parto entre as mulheres da Grande São Paulo do que do Interior (127,4 abortos a cada 1.000 partos na Grande São Paulo contra 90,9 no Interior. O tipo de aborto mais freqüente foi o aborto espontâneo (57,4% e a distribuição por idade mostra uma concentração entre os 20 e 29 anos, além de revelar que cerca de 20% deles ocorreram em adolescentes com menos de 19 anos.Despite the importance of the issue of abortion in Brazil, it is difficult to know the exact extent of the problem owing to the fact that it is an illegal practice. Information about hospitalizations from the Ministry of Health has helped an admittedly incomplete understanding of the situation with regard to abortions carried out in the SUS (Unified Health System hospital network. The objective of the study was to investigate the 53,861 hospitalizations diagnosed as abortion among women from 10 to 49 years of age in hospitals affiliated to SUS in the state

    Communities are structured by interactions of historical and ecological factors, which influence the use of different resources in time and space. We acquired data on time of activity, microhabitat use and diet of a lizard assemblage from a sand dune habitat in a coastal area, southeastern Brazil (Restinga de Jurubatiba). We analyzed the data of niche overlap among species in these three axes (temporal, spatial and trophic) using null models. We found a significant overlap within the trophic niche, whereas the overlap for the other axes did not differ from the expected. Based on this result, we discuss the factors acting on the structure of the local lizard community.

    Full Text Available The córrego Paulicéia is a direct tributary of the rio Mogi-Guaçu, located in Santa Rita do Passa Quatro, State of São Paulo, Southeastern Brazil. This stream runs inside a savannah-like (cerrado environment and it associated vegetation. Biological and ecomorphological aspects of its fish community were studied in three stretches of the stream, denominated herein as the upper, middle and lower courses. The fish fauna recorded in this study consisted of 15 species, belonging to five orders and nine families, based in a total of 715 collected individuals representing 1,450 kg of biomass. The most important abiotic factors related to the occurrence and distribution of the fish fauna were the substrate, current speed, and presence or absence of riparian vegetation. The analysis of 336 stomach contents of 13 species demonstrated that 65% of food items are autochthonous, 32% allochthonous, and 3% are of unknown origin. Four alimentary guilds could be identified, based on the predominant food items: omnivores with tendency to insectivory - Astyanax paranae, A. fasciatus and Piabina argentea; larvivores - Corydoras difluviatilis, Cetopsorhamdia iheringi, Phenacorhamdia tenebrosa, Characidium gomesi, Eigenmannia virescens, and Rhamdia quelen; periphyton feeders - Hisonotus sp., Hypostomus ancistroides and Synbranchus marmoratus; and piscivore - Hoplias malabaricus. Reproductions data are presented for Astyanax altiparanae and Hisontus sp. Three ecomorphological groups could be established, based on swimming, feeding, and microhabitat strategies: nektonic (A. fasciatus, A. paranae, Bryconamericus stramineus, P. argentea, H. malabaricus and Phallotorynus jucundus, benthic (C. gomesi, P. tenebrosa, C. iheringi, R. quelen, C. difluviatilis, H. ancistroides and Hisonotus sp., and necktobenthic (E. virescens and S. marmoratus.

    Photoacclimation of photosynthesis was investigated in a tropical population of C. glomerata (São Paulo State, southeastern Brazil, 20 degrees 48' 24" S and 49 degrees 22' 24" W) by chlorophyll fluorescence parameters and chlorophyll a content. Plants were acclimated to two levels of irradiance: low (65 +/- 5 micromol.m(-2).s(-1)) and high (300 +/- 10 micromol.m(-2).s(-1)) and exposed short-term (4 days) and long-term (28 days) under a light-dark cycle of 12:12 hours. Photosynthesis-irradiance (PI) curves revealed distinct strategies of photoacclimation. In long-term exposure, plants acclimated by altering the photosynthetic units (PSU) number and keeping fixed the PSU size, revealed by increased rates of maximum photosynthesis (Pmax), lower photosynthetic efficiency (alpha) and higher values of the saturation parameter (Ik) under high irradiance. The short-term acclimation strategy consisted of changing the PSU size, with a fixed number of PSUs, as revealed by similar Pmax but higher alpha and lower Ik under low irradiance. Chlorophyll a contents followed the general pattern reported in green algae of higher concentrations under lower irradiance. Dark/light induction curves revealed consistently higher values of potential quantum yield under low irradiance. Initial and final values showed a higher recovery capacity in the short (84.4-90.6%) term exposure than in the long-term case (81.4-81.5%). ETR (electron transport rate) and NPQ (non-photochemical quenching) values were consistently higher under low irradiance. ETR showed a continuous and steady increase along the light exposure period in the short and long-term experiments, whereas NPQ values revealed a rapid increase after 15 seconds of light exposure, kept a slightly increasing trend and stabilized in most treatments. Lower photosynthetic performance (ETR) and recovery capacity of potential quantum yield were observed, particularly in long-term exposure, suggesting that this population is constrained by the

    Enzootic bovine leucosis (EBL) is a silent disease caused by a retrovirus [bovine leukaemia virus (BLV)]. BLV is classified into almost 10 genotypes that are distributed in several countries. The present research aimed to describe two BLV gp51 env sequences of strains detected in the state of São Paulo, Brazil and perform a phylogenetic analysis to compare them to other BLV gp51 env sequences of strains around the world. Two bovines from different herds were admitted to the Bovine and Small Ruminant Hospital, School of Veterinary Medicine and Animal Science, University of São Paulo, Brazil. In both, lymphosarcoma was detected and the presence of BLV was confirmed by nested PCR. The neighbour-joining algorithm distance method was used to genotype the BLV sequences by phylogenetic reconstruction, and the maximum likelihood method was used for the phylogenetic reconstruction. The phylogeny estimates were calculated by performing 1000 bootstrap replicates. Analysis of the partial envelope glycoprotein (env) gene sequences from two isolates (25 and 31) revealed two different genotypes of BLV. Isolate 25 clustered with ten genotype 6 isolates from Brazil, Argentina, Thailand and Paraguay. On the other hand, isolate 31 clustered with two genotype 5 isolates (one was also from São Paulo and one was from Costa Rica). The detected genotypes corroborate the results of previous studies conducted in the state of São Paulo, Brazil. The prediction of amino acids showed substitutions, particularly between positions 136 and 150 in 11 out of 13 sequences analysed, including sequences from GenBank. BLV is still important in Brazil and this research should be continued.

    Full Text Available The concern in milk quality, milk production, and in animals’ welfare is in constant increase. Mastitis is recognized as the main disease affecting dairy animals because of changing in milk composition and reduction in milk production. In Brazil, the highest incidence of mastitis is related to infectious agents. This study aimed to investigate the incidence of pathogenic microorganisms in milk produced by 60 cows from four dairy farms (15 cows/farm located at Sao Paulo state, Brazil. Milk samples from each teat were collected fortnight in sterile tubes, previously identified, during two months. In each herd 240 samples were obtained, except on the farm A, where an extra collection was done, in a total amount of 300 samples. On the farm A, the sampling was done in a period of transition between the dry and rainy season. On the farm B, samples were collected mostly in the season of high temperatures. On the farm C the collections were made over a period of heat and humidity. On the farm D, on a period of warmer temperatures and reduced rainfall. The isolation and identification of microorganisms were conducted at Laboratory of Milk Quality from Instituto de Zootecnia, Nova Odessa, São Paulo, Brazil. Aliquots of 100 mL of milk were grown on plates with 5% sheep blood agar. After incubation, they were used for the production of catalase and Gram stain. Gram positive and catalase positive samples were classified as Corynebacterium spp. (Coryne.. Gram positive cocci and catalase negative samples were classified as Streptococcus spp. (Strepto.. Milk were then proceeded to coagulase test in rabbit plasma. Gram-positive cocci, catalase positive and coagulase-negative were classified as Staphylococcus coagulase-negative (SCN. Gram positive, catalase positive and coagulase positive samples were subsequently subjected to biochemical tests: mannitol salt agar, maltose, trehalose, and acetoin production. Strains that were positive for these tests were

    Access to, and use of, dental health services in Brazil have improved since 2003. The increase of private health care plans and the implementation of the "Smiling Brazil" Program, the largest public oral health care program in the world, could have influenced this increase in access. However, we do not yet know if inequalities in the use of dental health services persist after the improvement in access. The aims of this study are to analyze socioeconomic differences for dental health service use between 2003 and 2008 in São Paulo and to examine changes in these associations since the implementation of the Smiling Brazil program in 2003. Data was obtained via two household health surveys (ISA-Capital 2003 and ISA-Capital 2008) which investigated living conditions, lifestyle, health status and use of health care services. Logistic regression was used to analyze associations between socioeconomic factors and dental services use. Additionally, trends from 2003 to 2008 regarding socioeconomic characteristics and dental health service use were explored. Overall, dental health service use increased between 2003 and 2008 and was at both time points more common among those who had higher income, better education, better housing conditions, private health care plans and were Caucasian. Inequalities in use of dental health care did not decrease over time. Among the reasons for not seeking dental care, not having teeth and financial difficulty were more common in lower socioeconomic groups, while thinking it was unnecessary was more common in higher socioeconomic groups. The Brazilian oral health policy is still in a period of expansion and seems to have contributed slightly to increased dental health service use, but has not influenced socioeconomic inequalities in the use of these services. Acquiring deeper knowledge about inequalities in dental health service use will contribute to better understanding of potential barriers to reducing them.

    Full Text Available BACKGROUND: Over the last century the incidence of cutaneous melanoma has increased worldwide, a trend that has also been observed in Brazil. The identified risk factors for melanoma include the pattern of sun exposure, family history, and certain phenotypic features. In addition, the incidence of melanoma might be influenced by ethnicity. Like many countries, Brazil has high immigration rates and consequently a heterogeneous population. However, Brazil is unique among such countries in that the ethnic heterogeneity of its population is primarily attributable to admixture. This study aimed to evaluate the contribution of European ethnicity to the risk of cutaneous melanoma in Brazil. METHODOLOGY/PRINCIPAL FINDINGS: We carried out a hospital-based case-control study in the metropolitan area of Sao Paulo, Brazil. We evaluated 424 hospitalized patients (202 melanoma patients and 222 control patients regarding phenotypic features, sun exposure, and number of grandparents born in Europe. Through multivariate logistic regression analysis, we found the following variables to be independently associated with melanoma: grandparents born in Europe-Spain (OR = 3.01, 95% CI: 1.03-8.77, Italy (OR = 3.47, 95% CI: 1.41-8.57, a Germanic/Slavic country (OR = 3.06, 95% CI: 1.05-8.93, or ≥ 2 European countries (OR = 2.82, 95% CI: 1.06-7.47; eye color-light brown (OR = 1.99, 95% CI: 1.14-3.84 and green/blue (OR = 4.62; 95% CI 2.22-9.58; pigmented lesion removal (OR = 3.78; 95% CI: 2.21-6.49; no lifetime sunscreen use (OR = 3.08; 95% CI: 1.03-9.22; and lifetime severe sunburn (OR = 1.81; 95% CI: 1.03-3.19. CONCLUSIONS: Our results indicate that European ancestry is a risk factor for cutaneous melanoma. Such risk appears to be related not only to skin type, eye color, and tanning capacity but also to others specific characteristics of European populations introduced in the New World by European immigrants.

    To perform both space and space-time evaluations of visceral leishmaniasis in humans in the state of Sao Paulo, Brazil. The population considered in the study comprised autochthonous cases of visceral leishmaniasis and deaths resulting from it in Sao Paulo, between 1999 and 2013. The analysis considered the western region of the state as its studied area. Thematic maps were created to show visceral leishmaniasis dissemination in humans in the municipality. Spatial analysis tools Kernel and Kernel ratio were used to respectively obtain the distribution of cases and deaths and the distribution of incidence and mortality. Scan statistics were used in order to identify spatial and space-time clusters of cases and deaths. The visceral leishmaniasis cases in humans, during the studied period, were observed to occur in the western portion of Sao Paulo, and their territorial extension mainly followed the eastbound course of the Marechal Rondon highway. The incidences were characterized as two sequences of concentric ellipses of decreasing intensities. The first and more intense one was found to have its epicenter in the municipality of Castilho (where the Marechal Rondon highway crosses the border of the state of Mato Grosso do Sul) and the second one in Bauru. Mortality was found to have a similar behavior to incidence. The spatial and space-time clusters of cases were observed to coincide with the two areas of highest incidence. Both the space-time clusters identified, even without coinciding in time, were started three years after the human cases were detected and had the same duration, that is, six years. The expansion of visceral leishmaniasis in Sao Paulo has been taking place in an eastbound direction, focusing on the role of highways, especially Marechal Rondon, in this process. The space-time analysis detected the disease occurred in cycles, in different spaces and time periods. These meetings, if considered, may contribute to the adoption of actions that aim to

    In agricultural landscapes, studies that identify factors driving species richness and occupancy are important because they can guide farmers to use conservation practices that minimize species loss. In this context, anurans are threatened by habitat loss because they depend on the characteristics of both local water bodies and adjacent landscapes. We used a model selection approach to evaluate the influence of local and landscape variables in determining anuran species richness and occurrence in 40 freshwater bodies in a heavily deforested region of semideciduous Atlantic Forest in southeastern Brazil. Our aim was to develop recommendations for conservation of anuran communities in rural areas. Pond hydroperiod and area were the most important variables for explaining anuran species richness and occupancy, with greatest species richness being found in water bodies with intermediate hydroperiod and area. Other important variables that reflected individual species occupancies were the number of vegetation types and pond isolation. In addition, recent studies evidenced that water bodies near forest fragments have higher anuran abundance or diversity. In conclusion, we suggest the maintenance of semi-permanent ponds, isolated from large rivers or reservoirs and near forest fragments, as an effective strategy to conserve anuran fauna in agricultural landscapes of southeastern Brazil. Brazilian government requires the maintenance of forests as legal reserve in each farm, and farmers need to maintain ponds as drinking water for cattle or crop irrigation. For this reason, the guidelines suggested in the present study can be easily adopted, without additional costs to rural productivity.

    Full Text Available The upper montane forests in the southern and southeastern regions of Brazil have an unusual and discontinuous geographic distribution at the top of the Atlantic coastal mountain ranges. To describe the floristic composition and structure of the Atlantic Forest near its upper altitudinal limit in southeastern Brazil, 30 plots with 10 × 10 m were installed in three forest sites between 2,200 and 2,300 m.a.s.l. at Serra Fina. The floristic composition and phytosociological structure of this forest were compared with other montane and upper montane forests. In total, 704 individuals were included, belonging to 24 species, 15 families, and 19 genera. Myrsinaceae, Myrtaceae, Symplocaceae, and Cunoniaceae were the most important families, and Myrsine gardneriana, Myrceugenia alpigena, Weinmannia humilis, and Symplocos corymboclados were the most important species. The three forest sites revealed differences in the abundance of species, density, canopy height, and number of stems per individual. The upper montane forests showed structural similarities, such as lower richness, diversity, and effective number of species, and they tended to have higher total densities and total dominance per hectare to montane forests. The most important species in these upper montane forests belong to Austral-Antartic genera or neotropical and pantropical genera that are typical of montane areas. The high number of species shared by these forests suggests past connections between the vegetation in southern Brazilian high-altitude areas.

Defoliations around 80% and 50% were observed in the common bean cv. Pérola and castor bean cv. IAC-2028, respectively. Samples of individuals (caterpillars and pupae were collected in the field, and kept in laboratory until adult emergence aiming to confirm the species. These are new observations for common bean in São Paulo State and, in the case of castor bean, unpublished in Brazil. It suggests that C. includens has adapted to attack other agricultural crops, demanding attention of common bean and castor bean producers.

    Guidelines for the treatment of psychoses recommend antipsychotic monotherapy. However, the rate of antipsychotic polytherapy has increased over the last decade, reaching up to 60% in some settings. Studies evaluating the costs and impact of antipsychotic polytherapy in the health system are scarce. To estimate the costs of antipsychotic polytherapy and its impact on public health costs in a sample of subjects with psychotic disorders living in residential facilities in the city of Sao Paulo, Brazil. A cross-sectional study that used a bottom-up approach for collecting costs data in a public health provider's perspective. Subjects with psychosis living in 20 fully-staffed residential facilities in the city of Sao Paulo were assessed for clinical and psychosocial profile, severity of symptoms, quality of life, use of health services and pharmacological treatment. The impact of polytherapy on total direct costs was evaluated. 147 subjects were included, 134 used antipsychotics regularly and 38% were in use of antipsychotic polytherapy. There were no significant differences in clinical and psychosocial characteristics between polytherapy and monotherapy groups. Four variables explained 30% of direct costs: the number of antipsychotics, location of the residential facility, time living in the facility and use of olanzapine. The costs of antipsychotics corresponded to 94.4% of the total psychotropic costs and to 49.5% of all health services use when excluding accommodation costs. Olanzapine costs corresponded to 51% of all psychotropic costs. Antipsychotic polytherapy is a huge economic burden to public health service, despite the lack of evidence supporting this practice. Great variations on antipsychotic costs explicit the need of establishing protocols for rational antipsychotic prescriptions and consequently optimising resource allocation. Cost-effectiveness studies are necessary to estimate the best value for money among antipsychotics, especially in low and middle

This river is considered one of the most polluted rivers in the world, especially when it passes through the city of Sao Paulo. As a result of pollution observed since the 1950's, a project was established with the aim of evaluating the historic concentration of the trace elements As, Ba, Br, Ca, Ce, Co, Cr, Cs, Eu, Fe, Hf, La, Lu, Na, Nd, Rb, Sb, Sc, Sm, Ta, Tb, Th, U, Yb and Zn (mg.kg{sup -1}), in sediment cores dated by {sup 210}Pb method, sampled is several points of the river, since its source in Salesopolis up the mouth, on the Parana River. This work presents the results obtained by the trace elements above determined in two sediment cores collected in reservoirs in the city of Salesopolis and Pirapora do Bom Jesus. The analytical techniques used for the analysis were instrumental neutron activation analysis and gross beta measurement, respectively. The results obtained for the elements Br, Ce, Cr, Cs, Eu, Nd, Sb, Sm, Th and U are higher than the values of Upper Continental Crust and the sedimentation rate obtained for the reservoir in Salesopolis, 1.53 cm.y{sup -1}, suggest silting processes. The enrichment factor and the geo-accumulation index were used to assess the presence of anthropogenic sources of pollution. Document available in abstract form only. (authors)

    Pb-210 (T{sub 1/2} = 22.3 y), a natural radionuclide from U-238 serie can be found in the atmosphere, as a product of {sup 222}Rn decay that emanates from the ground, where its atoms become rapidly fixed to aerosols and return to the earth as dry fallout or are washed out in the rain. This natural radionuclide has been widely used as an atmospheric tracer, to determine the aerosol residence time as well as chronometers in the environment. Pb-210 was measured during a period of two years, 2011 to 2013, in samples of rainfall in all the rainy events that occurred at the Instituto de Pesquisas Energeticas e Nucleares (IPEN) campus (23 deg 33’59.24” S - 46 deg 44’15.63” O at 760 m above sea level) which is located in the city of Sao Paulo, in the state of Sao Paulo, Brazil. Pb-210 concentration was measured in a total of 123 rainy events by beta gross counting in a low background gas flow proportional detector, after radiochemistry procedure. The results obtained were correlated to seasons and rainfall. The concentrations of {sup 210}Pb in rainfall varied from the minimum detectable activity, 4.9 mBq L{sup -1} to 1408± 43 mBq L{sup -1}. The highest concentrations were obtained in the months of winter and the lowest in summer. The monthly depositional flux of {sup 210}Pb, varied from 4.03 Bq m{sup -2} month{sup -1} to 46.4 Bq m{sup -2} month{sup -1}presenting a strong correlation with the amount of precipitation and hence showing seasonal trends.

    Full Text Available ABSTRACT Acute hemorrhagic conjunctivitis (AHC infection is highly contagious and can lead to explosive epidemics. In early February 2011, the Center for Epidemiologic Surveillance of the State of São Paulo Health Secretariat (SES-SP in Brazil received reports of conjunctivitis outbreaks from rural areas of the state that subsequently spread statewide. This report describes that AHC epidemic and its etiologic agent. Data from the Ministry of Health Information System for Notifiable Diseases (SinanNet and the SES-SP epidemiologic surveillance system for conjunctivitis, developed to detect outbreaks, confirm the etiologic agent, and carry out control measures, were analyzed. Eye (conjunctival swab samples were taken from patients with clinical presentation of viral conjunctivitis to perform viral laboratory diagnosis. A total of 1 067 981 conjunctivitis cases were reported to the surveillance system for 2011; there was an increase in the number of cases in epidemiologic weeks 6–26 (summer season versus previous years. Most cases occurred in the metropolitan region of Greater São Paulo. Of 93 collected samples, 57 tested positive for coxsackievirus-A24 (CV-A24, based on virus isolation in tissue-culture cell lines, reverse transcription polymerase chain reaction (RT-PCR, and enterovirus sequencing of RT-PCR. The data analysis showed that the fast-spreading etiologic agent of the AHC epidemic that occurred in the summer of 2011 was CV-A24. The AHC epidemic was due to an enterovirus that occurred sporadically, spread rapidly and with great magnitude, and had substantial socioeconomic impact due to the high level of absenteeism at work and school.

    Full Text Available INTRODUCTION: The lack of basic knowledge on venomous arthropods and the benignity of the clinical manifestations contribute to the centipede bite victims' not being taken to a treatment reference center, leading to underestimation of the number of cases and minimizing the possibility of a broader epidemiological view. An inventory of the centipede bite occurrences in Greater S. Paulo, Brazil, and the therapeutic methods employed, by the main Brazilian medical center for the notification of poisoning by venomous animals, is presented. METHOD: All patient cards of the period 1980-1989 have been checked as to place, month and time of occurrence; sex, age, affected part of the body, signs and symptoms have been observed, as well as the therapeutic methods employed. The centipedes that caused the accidents were identified at the Arthropods Laboratory. RESULTS: It was registered 216 accidents, with a 69% predominance of the Greater S. Paulo and in only 63% of the cases (136 was the agent brought in by the victim for identification. The genera most frequently represented were Cryptops (58%, Otostigmus (33% and Scolopendra (4%. Of the 136 cases, 87% showed erythema, edema, hemorrhage, burns, cephalalgia, and intense pain. There was a predominance of accidents in the warm rainy season, in the morning and for females between 21 and 60 years of age. Hands and feet were the parts of the body most affected. The benign evolution of the clinical picture (54% made therapeutical treatment unnecessary. Only the victims of Scolopendra and Otostigmus (46% were medicated with anesthetics (51%, analgesics (25%, antihistamines and cortisone (24%. CONCLUSION: The reproductive period of the centipedes, associated with their sinanthropic habits, contributes to the greater incidence of accidents in urban areas in the warm rainy season. Only patients bitten by Scolopendra and Otostigmus require therapeutical treatment.

    Full Text Available A cross sectional study was carried out between May and November 2011 to investigate the epidemiological situation of bovine tuberculosis (bTB in the state of São Paulo, Brazil. The state was divided into seven regions. Three hundred farms from each region, with reproductive activity, were randomly chosen and included as primary sample units. A fixed number of bovine females, older than 2 years of age, were randomly selected and tested, using the comparative cervical tuberculin test. An epidemiological questionnaire based survey was conducted in the selected farms. Our results show that in the state of São Paulo, the apparent prevalence of positive farms was 9% (95% confidence interval, 95% CI = 7.8 – 10.5%. The prevalence in the individual regions varied between 3.5% (95% CI = 1.7 ? 6.8% and 13.9% (95% CI = 10.2 – 18.8%. The apparent prevalence of positive animals in the state was 1.3% (95% CI = 0.9 – 1.7% and varied from 0.3% (95% CI = 0.2 – 0.6% to 2.5% (95% CI = 1.4 – 4.5% in the regions. The risk factors associated with tuberculosis in the state were (i number of adult females in a herd is ? 24 (Odds ratio, OR = 1.91, 95% CI = 1.32 – 2.75, (ii type of farm enterprise (dairy: OR = 2.70, 95% CI = 1.40 – 5.21; mixed: OR = 2.03, 95% CI = 1.08 – 3.82, (iii milking process (milking parlor: OR = 4.12, 95% CI = 1.46 – 11.64; portable milking machine: OR = 2.94, 95% CI = 1.42 – 6.09, and (iv pasture sharing (OR = 1.58, 95% CI = 1.07 – 2.33. The state of São Paulo should implement a structured surveillance system to detect and mitigate the disease. Further, an efficient animal health education program, which encourages the farmers to test replacement animals for bTB prior to introduction in their herds and to avoid pasture sharing with farms of unknown sanitary conditions should also be implemented.

    Background Thyroid cancer incidence has risen steadily over the last few decades in most of the developed world, but information on incidence trends in developing countries is limited. Sao Paulo, Brazil, has one of the highest rates of thyroid cancer worldwide, higher than in the United States. We examined thyroid cancer incidence patterns using data from the Sao Paulo Cancer Registry (SPCR) in Brazil and the National Cancer Institute's Surveillance Epidemiology End Results (SEER) program in the United States. Methods Data on thyroid cancer cases diagnosed during 1997–2008 were obtained from SPCR (n=15,892) and SEER (n=42,717). Age-adjusted and age-specific rates were calculated by sex and histology and temporal patterns were compared between the two populations. Results Overall incidence rates increased over time in both populations and were higher in Sao Paulo than in the United States among females (SPCR/SEER incidence rate ratio [IRR]=1.65) and males (IRR=1.23). Papillary was the most common histology in both populations, followed by follicular and medullary carcinomas. Incidence rates by histology were consistently higher in Sao Paulo than in the United States, with the greatest differences for follicular (IRR=2.44) and medullary (IRR=3.29) carcinomas among females. The overall female/male IRR was higher in Sao Paulo (IRR=4.17) than in SEER (IRR=3.10) and did not change over time. Papillary rates rose over time more rapidly in Sao Paulo (annual percentage change=10.3% among females and 9.6% among males) than in the United States (6.9% and 5.7%, respectively). Regardless of sex, rates rose faster among younger people (8 among both Sao Paulo males and females, in contrast to increases from 9 to 12 and from 6 to 7 among U.S.males and females, respectively. Conclusions Increased diagnostic activity may be contributing to the notable rise in incidence, mainly for papillary type, in both populations, but it is not likely to be the only reason.

    Full Text Available Epstein-Barr virus (EBV is a ubiquitous herpesvirus, and most people have serological evidence of previous viral infection at adult age. EBV is associated with infectious mononucleosis and human cancers, including some lymphomas and gastric carcinomas. Although EBV was first reported in lymphoepithelioma-like gastric carcinoma, the virus was also found in conventional adenocarcinomas. In the present study, 53 gastric carcinomas diagnosed in São Paulo State, Brazil, were evaluated for EBV infection by non-isotopic in situ hybridization with a biotinylated probe (Biotin-AGACACCGTCCTCACCACCC GGGACTTGTA directed to the viral transcript EBER-I, which is actively expressed in EBV latently infected cells. EBV infection was found in 6 of 53 (11.32% gastric carcinomas, mostly from male patients (66.7%, with a mean age of 59 years old. Most EBV-positive tumors were in gastric antrum. Two EBV-positive tumors (33.3% were conventional adenocarcinomas, whereas four (66.7% were classified as lymphoepithelioma-like carcinomas. EBV infection in gastric carcinomas was reported elsewhere in frequencies that range from 5.6% (Korea up to 18% (Germany. In Brazil, a previous work found EBV infection in 4 of 80 (5% gastric carcinomas, whereas another study found 4.7 and 11.2% of EBV-positive gastric carcinomas of Brazilians of Japanese origin or not, respectively. In the present study, the frequency of EBV-positive gastric carcinomas is similar to that reported in other series, and the clinicopathologic characteristics of these EBV-positive tumors are in agreement with the data in the literature.

    Full Text Available BACKGROUND: Genetic variability is a major feature of the human immunodeficiency virus type 1 (HIV-1 and considered the key factor to frustrating efforts to halt the virus epidemic. In this study, we aimed to investigate the genetic variability of HIV-1 strains among children and adolescents born from 1992 to 2009 in the state of Sao Paulo, Brazil. METHODOLOGY: Plasma and peripheral blood mononuclear cells (PBMC were collected from 51 HIV-1-positive children and adolescents on ART followed between September 1992 and July 2009. After extraction, the genetic materials were used in a polymerase chain reaction (PCR to amplify the viral near full length genomes (NFLGs from 5 overlapped fragments. NFLGs and partial amplicons were directly sequenced and data were phylogenetically inferred. RESULTS: Of the 51 samples studied, the NFLGs and partial fragments of HIV-1 from 42 PBMCs and 25 plasma were successfully subtyped. Results based on proviral DNA revealed that 22 (52.4% patients were infected with subtype B, 16 (38.1% were infected with BF1 mosaic variants and 4 (9.5% were infected with sub-subtype F1. All the BF1 recombinants were unique and distinct from any previously identified unique or circulating recombinant forms in South America. Evidence of dual infections was detected in 3 patients coinfected with the same or distinct HIV-1 subtypes. Ten of the 31 (32.2% and 12 of the 21 (57.1% subjects with recovered proviral and plasma, respectively, protease sequences were infected with major mutants resistant to protease inhibitors. The V3 sequences of 14 patients with available sequences from PBMC/or plasma were predicted to be R5-tropic virus except for two patients who harbored an X4 strain. CONCLUSIONS: The high proportion of HIV-1 BF1 recombinant, coinfection rate and vertical transmission in Brazil merits urgent attention and effective measures to reduce the transmission of HIV among spouses and sex partners.

    Full Text Available ABSTRACT In Brazil, specifically in São Paulo State, there are guidelines based on the high diversity of tropical forests that instructs the restoration projects in the state (current SMA 32/2014. The main goal of this study was verify the importance and effectiveness of the high diversity of arboreal species originated from a reforestation, and its influence in a woody regenerating composition. We developed a phytosociologic study in a woody regenerating stratum of a nine year old reforestation at a Private Reserve of Natural Heritage (RPPN, in Mogi-Guaçu, São Paulo State. All specimens with height > 30 cm and Diameter at Breast Height (DBH < 5 cm were evaluated. The woody regenerating diversity was smaller than the overstory diversity and the species composition was similar to the overstory. The Simpson index (1-D was 0.85, Shannon index (H' was 2.46 and the Pielou index (J' was 0.60. The zoochoric dispersion syndrome was major among the species. Our results suggest that the use of high diversity of native seedlings in a reforestation leads to high diversity of species in woody regeneration stratum, after one decade of planting.

    The Sao Sebastiao Channel, located at the coast of the State of Sao Paulo, Brazil, holds the largest oil terminal in the country, besides a small harbor and an extensive touristic activity. Since 1969, when the oil terminal was installed, the area has been submitted to chronic oil pollution due to the terminal's activities and to a number of spills of different magnitudes, caused by accidents with oil tankers. Sewage disposal is another cause of impact in the area. In a research conducted in CETESB's laboratory at the marine Biology Center from University of Sao Paulo, the occurrence of lethal and sublethal effects of seawater samples from that region, on the mysid shrimp Mysidopsis juniae, was analyzed in short-term chronic toxicity tests. The water samples were collected seasonally, for 18 months, at ten stations of the channel. The test endpoints were survival, growth and fecundity. The occurrence of abnormalities was also registered. Survival and length were not significantly affected, and fecundity. The occurrence of abnormalities was also registered. Survival and length were not significantly affected, and fecundity did not reach the minimum acceptable value for controls, of 50%. Dry weight data indicated a detrimental effect of some samples. This could be caused by a lowered lipid content. Abnormalities in the uropod and telson development were observed for some treatments

    Full Text Available OBJECTIVE: Celiac disease is a permanent enteropathy caused by the ingestion of gluten, which leads to an immunemediated inflammation of the small intestine mucosa. The prevalence of celiac disease varies among different nations and ethnic backgrounds, and its diversity is determined by genetic and environmental factors. São Paulo city is one of the largest cities in the world, with a vast population and an important history of internal migratory flow from other Brazilian regions, as well as immigration from other, primarily European, countries, resulting in significant miscegenation. The aim of the present study was to estimate the prevalence of adults with undiagnosed celiac disease among blood donors of São Paulo by collecting information on the ancestry of the population studied. METHODS: The prevalence of celiac disease was assessed by screening for positive IgA transglutaminase and IgA endomysium antibodies in 4,000 donors (volunteers in the Fundação Pró-Sangue Blood Center of São Paulo, São Paulo, Brazil. The antibody-positive subjects were asked to undergo a small bowel biopsy. RESULTS: Of the 4,000 subjects, twenty-four had positive tests, although both antibody tests were not always concordant. For example, ten subjects were positive for IgA tissue transglutaminase only. In twenty-one positive patients, duodenal biopsies were performed, and the diagnosis of celiac disease was confirmed in fourteen patients (Marsh criteria modified by Oberhuber. In this group, 67% claimed to have European ancestry, mainly from Italy, Portugal and Spain. CONCLUSION: The prevalence of celiac disease is at least 1:286 among supposedly healthy blood bank volunteers in São Paulo, Brazil.

    Local Climate Zones Classification to Urban Planning in the Mega city of São Paulo - SP, Brazil Tropical megacities have presented a strong trend in growing urban. Urban management in megacities has as one of the biggest challenges is the lack of integration of urban climate and urban planning to promote ecologically smart cities. Local Climatic Zones (LCZs) are considered as important and recognized tool for urban climate management. Classes are local in scale, climatic in nature, and zonal in representation. They can be understood as regions of uniform surface cover, structure, material and human activity that have to a unique climate response. As an initial tool to promote urban climate planning, LCZs represent a simple composition of different land coverages (buildings, vegetation, soils, rock, roads and water). LCZs are divided in 17 classes, they are based on surface cover (built fraction, soil moisture, albedo), surface structure (sky view factor, roughness height) and cultural activity (anthropogenic heat flux). The aim of this study is the application of the LCZs classification system in the megacity of São Paulo, Brazil. Located at a latitude of 23° 21' and longitude 46° 44' near to the Tropic of Capricorn, presenting humid subtropical climate (Cfa) with diversified topographies. The megacity of São Paulo currently concentrates 11.890.000 inhabitants is characterized by large urban conglomerates with impermeable surfaces and high verticalization, having as result high urban heat island intensity. The result indicates predominance in urban zones of Compact low-rise, Compact Mid-rise, Compact High-rise and Open Low-rise. Non-urban regions are mainly covered by dense vegetation and water. The LCZs classification system promotes significant advantages for climate sensitive urban planning in the megacity of São Paulo. They offers new perspectives to the management of temperature and urban ventilation and allows the formulation of urban planning

    Full Text Available Introduction: Vaccination is the main preventive strategy against Yellow Fever (YF, which is a public health concern in Brazil. However, HIV-infected patients might have insufficient knowledge regarding YF, YF prevention, and vaccines in general. Methods: In this questionnaire-based study, data from 158 HIV-infected individuals were addressed in three distinct outpatient clinics in São Paulo. Information was collected on demographic and clinical characteristics, as well as patients' knowledge of vaccines, YF and YF preventive strategies. In addition, individual YF vaccine recommendations and vaccine status were investigated. Results: Although most participants adequately ascertain the vaccine as the main prevention strategy against YF, few participants were aware of the severity and lack of specific treatment for YF. Discrepancy in YF vaccine (patients who should have taken the vaccine, but did not was observed in 18.8% of participants. Conclusion: YF is an important and preventable public health concern, and these results demonstrate that more information is necessary for the HIV-infected population.

    Nicotiana tabacum 'Bel W3' is a widely used sensitive bioindicator for ambient ozone, but it is rarely used in tropical countries. Our goal was to determine the suitability of this plant for biomonitoring ozone in the city of Sao Paulo by evaluating the relationships between leaf necroses and ozone under field conditions and measurements of chlorophyll a fluorescence and antioxidants in plants exposed to different concentrations of ozone in closed chambers. While a weak linear relationship between leaf injury and ozone concentrations (R 2 = 0.10) was determined in the field, a strong linear relationship was observed in the chamber experiments. Maximum leaf injury was observed in plants submitted to 40 ppb, which coincided with a significant decrease in fluorescence and total ascorbic acid. The relationship between leaf damage observed in the field and ozone was improved when the concentrations were limited to 40 ppb (R 2 = 0.28). - Nicotiana tabacum 'Bel W3' is suitable for indicating low ozone levels in Brazil

    Full Text Available Pesticides in “PERA” orange samples (N = 57 from São Paulo City, Brazil were assessed and the pesticide intake contribution was estimated for chronic risk assessment. Seventy-six pesticides were evaluated by the gas chromatography multi-residue method, including isomers and metabolites (4.332 determinations. The mean recoveries at the limit of quantification level were in the range of 72-115% and the relative standard deviation for five replicate samples was 1-11%. The limits of detection and quantification ranged from 0.005 to 0.4 mg.kg−1 and from 0.01 to 0.8 mg.kg−1, respectively. Pesticides were found in 42.1% of the samples at levels ranging from 0.06 to 2.9 mg.kg−1. Of the contaminated samples, 3.5% contained residues (bifenthrin and clofentezine above the maximum residue level and 12.3% contained unauthorized pesticides (azinphos-ethyl, parathion, myclobutanil, profenofos, and fenitrothion. The estimated risk characterization for orange intake by adults and children, respectively, ranged from 0.04 to 6.6% and from 0.1 to 26.5% of the acceptable daily intake. The detection of irregular residues emphasizes the need for better implementation of Good Agriculture Practices and greater control of formulated products. Other pesticides surveyed did not pose a health risk due to consumption.

    Full Text Available ABSTRACT Objective To assess overweight/obesity of elementary schoolchildren in Campinas , São Paulo , Brazil, and its association with parental nutritional status, children's food consumption, food preferences, and level of physical activity, and familial socioeconomic status. Methods This case-control study included 509 schoolchildren aged 7 to 10 years. Body mass index Z-score was used to determine nutritional status, defining cases (>+1 Z-score and controls (³-2 ?+1 Z-score. To address association with overweight/obesity, a conceptual model was established and used for multiple analysis, performed by logistic regression. Results The children had an overweight/obesity frequency of 39.5%. Multiple analysis adjusted for socioeconomic level showed that overweight/obese children were more likely to eat at the mall (1.55; 95%CI=1.00-2.40, have overweight and obese parents (OR=1.71; 95%CI=1.08-2.71 and OR=3.55; 95%CI=2.18-5.80 respectively, report use of passive school transport (OR=1.57; 95%CI=1.04-2.36, and consume chicken nuggets on 3 or more days per week (OR=3.03; 95%CI=1.32-6.95. Conclusion These results support the urgent need of strategies to reduce overweight/obesity and promote its prevention in schoolchildren. Moreover, intervention studies involving parents and addressing environmental factors are important for the development of effective programs.

    Full Text Available Pythiosis is a granulomatous lesion of the skin and subcutaneous tissues caused by Pythium insidiosum, a microorganism belonging to the Stramenopila Kingdom and the Oomycetes Class. The pathogen is commonly found in water environments, mainly in tropical areas of the world. Twenty eight cases of equine pythiosis were presented at the Large Animal Surgery Department of the School of Veterinary Medicine and Animal Science, São Paulo State University, Brazil in six years. Among the 28 animals, 13 presented distal lesions on the limbs, with four being immediately euthanized and seven dying due to loss of body condition leading to cachexia. The horses presented with one or more wounds in the body, distributed as follows: limbs (13 distal, four proximal, abdominal region (7, thoracic region (1, pectoral region (1, lumbar region (1, nasal region (1 and prepuce (1. The diagnosis was made by the association of the macroscopic aspects of the lesions with the histopathology, isolation of the pathogen and/or nested-PCR. Treatments included surgical removal of the lesion (16, potassium iodide 67 mg kg-1 PO sid (23, intravenous regional perfusion with 50 mg of amphotericin B (6 and immunotherapy (8. Pythiosis is a disease that develops quickly, but its diagnosis is time-consuming; therefore, establishing an early treatment with special attention to the involvement of distal regions of the limbs is important.

    Full Text Available Abstract The objective of this study was to assess the perceptions of opinion-leaders, patients and their accompanying family members or carers about generic drugs. Three groups of participants were surveyed: (i 50 customers while they were visiting commercial pharmacies located in São Paulo city, Brazil, (ii 25 patients and 25 companions while they were waiting at the university outpatient clinic, and (iii 50 healthcare opinion-leaders from government, hospitals, health plans, academia, and pharmaceutical companies. The questions explored socio-demographic characteristics and perceptions regarding value attributes of generic drugs compared to brand name drugs. Respondents had an average age of 52 years and 53% were women. Respondents believed generic drugs to be cheaper than brand name drugs (97%, and 31% thought generic drugs to be less effective than brand name drugs. Also, generic drugs were perceived by 54% of respondents to be as safe as brand name drugs and 74% would prefer brand name drugs if there was no price difference. In conclusion, multiple factors may contribute to the decision to buy generic drugs; among these, perceived effectiveness, safety and price appear to be the most important factors.

    Full Text Available Increasing urbanization across the globe, combined with an increased use of chemicals in various regions, contributes to several environmental events that influence environmental health. Measures that identify environmental factors and events should be introduced to facilitate epidemiological investigations by health services. The Brazilian Ministry of Health published a new list of notifiable diseases on 25 January 2011 and introduced environmental events as a new category of notifiable occurrences. The Center for Epidemiologic Surveillance in State of Sao Paulo, Brazil, created an online notification system that highlights “environmental events”, such as exposure to chemical contaminants, drinking water with contaminants outside of the recommended range, contaminated air, and natural or anthropogenic disasters. This paper analyzed 300 notifications received between May 2011 and May 2012. It reports the number of notifications with event classifications and analyzes the events relating to accidents with chemical substances. This paper describes the characteristics of the accidents that involved chemical substances, methods used, types of substances, exposed population, and measures adopted. The online notification of environmental events increases the analysis of the main events associated with diseases related to environmental chemicals; thus, it facilitates the adoption of public policies to prevent environmental health problems.

    The mullet (Mugilidae) is a fish caught in large quantities in brackish and marine waters of the southern Brazilian coast, which in consequence of its raw consumption as ''sashimi'', a typical Japanese dish, has led to ten cases of human infection by Phagicola longa in Sao Paulo, Brazil. The mullet acts as a second intermediate host for the parasite, as in human heterophyiasis in the Near and Far East. In order to control these infections under commercial storage conditions and in raw consumption, the radiolysis of P. longa was studied in three mullet species - the silver mullet (Mugil curema), the grey mullet (M. platanus) and the ''paratipema'' (Mugil sp.) -subjected to ionization ranging from 1.0 to 10.0 kGy (2.21 kGy/h). It was observed that 1.0 and 2.0 kGy caused a motility decrease in silver mullet parasites from 100% to 15% and 17%, and that doses of 4.0 and 10.0 kGy caused metacercaria inviability. The parasite motility decreased in the grey mullet treated with doses of 2.0, 2.5, 3.0 and 3.5 kGy, from 56% to 31%, 9%, 18% and 5%, respectively, 4.0 kGy tending to be the control dose for P. Longa. This dose also controls other metacercaria found in the ''parati-pema'', without changing the odor, color or appearance of the treated mullet. (author)

    Full Text Available A two-stage cluster sample design was used to estimate population parameters of dogs and cats of the urban area of Votorantim, São Paulo State, Brazil, to support the planning and implementation of population management programs for companion animals. For dogs, the total and density estimates were 27,241 dogs (95% confidence interval [CI]=23,903-30,578 and 951 dogs km-2 (95% CI=835-1,068, respectively. For cats, these estimates were 5,579 cats (95% CI=3,595-7,562 and 195 cats km-2 (95% CI=126-264. Cost was the most prevalent reason for not sterilizing the animals (33%, 95% CI=23%-44%, Deff=6.1. The percentage of interviewees that expressed reasons for abandoning their animals was equal to 9 (95% CI=5-13, Deff=2.1. Other estimates were obtained, including indirect estimates of abandonment. The estimates associated with abandonment suggest that the prevalence of this phenomenon can significantly affect population dynamics. Distribution of dogs per household can be used to construct hypothetical populations and to validate estimation procedures. The estimates generated allow parameterizing mathematical models and constructing population management indicators

    Full Text Available We conducted monthly snail captures in Bananal, State of São Paulo, Brazil, between March 1998 and February 2001, to identify Schistosoma mansoni vectors, estimate seasonal population changes, and delimit foci. We also evaluated the impact of improvements in city water supply and basic sanitation facilities. We identified 28,651 vector specimens, 28,438 as Biomphalaria tenagophila, 49 of them (0.2% infected with S. mansoni, and 213 as B. straminea, none of the latter infected. Vectors predominated in water bodies having some vegetation along their banks. Neither population density nor local vegetation could be linked to vector infection. We found the first infected snails in 1998 (from March to May. Further captures of infected snails ocurred, without exception, from July to December, when rainfall was least. Irrespective of season, overall temperature ranged from 16.5ºC to 21ºC; pH values, from 6.0 to 6.8. Neither factor was associated with snail population density. Frequent contact of people with the river result from wading across it, extracting sand from its bottom, fishing, washing animals, etc. Despite a marked reduction in contamination, cercaria shedding persists. Whatever the location along its urban course, contact with river Bananal, particularly of the unprotected skin, entails risks of infection.

    In the present study, the concentration and distribution of Ba, Cu, Mo, Pb, S, Zn and Zr in soils collected along two main avenues (Pinheiros River Highway and Tiete River Highway) with high traffic density in the metropolitan region of Sao Paulo, Brazil, are presented, and their possible sources are discussed. These elements are strongly considered as contaminants originated from vehicular emissions. The analytical technique employed was XRF. The data set was evaluated by a t test for independent samples (group: avenues) at a 0.05 significance level. According to t test, the average contents obtained from Pinheiros River Highways are significantly different than the Tiete River, except for Mo. Multivariate statistic approaches (Pearson Correlation, Cluster and Factorial Analysis - FA) were adopted for data treatment. FA identified two main factors which accounted for about 86% of the total variance. The behavior of Ba, Cu, Pb, S and Zn were explained by the Factor 1. This indicates that the elements may have similar sources, probably related to gas emissions escaping from the vehicle fuel system. Factor 2 included Mo and Zr, suggesting their origin in the sample soils may be associated with the deterioration process of some device in the vehicular engine system or may be associated with the chemical composition of the urban soil analyzed.

    Little is known about the use of psychotherapy to treat common mental disorders in a major city in a middle income country. Data come from in-home interviews with a stratified random sample of 2,000 community residents age 18–65 in the city of São Paulo, Brazil. The information obtained included sociodemographic characteristics; psychotropic drugs; mental status; and lifetime, previous 12 months, and current use of psychotherapy. Logistic regression was used to examine determinants of use of psychotherapy. Of the sample, 22.7% met General Health Questionnaire-12 criteria for common mental disorders. Lifetime, previous 12 months, and current use of psychotherapy were reported by 14.6%, 4.6%, and 2.3% of the sample respectively. Users were typically women, more educated, higher income, not married, unemployed, with common mental disorders. Further analysis found that 47% (with higher education and income) paid out-of-pocket, and 53% used psychotropic medication. Psychotherapy does not appear to be the preferred treatment for common mental disorders. PMID:25118139

    Full Text Available The article presents preliminary data from a prospective investigation in a sample of healthy 14-17-year-old students from a technical school in Sao Paulo, Brazil. Ninety-six Tanner stage 5 and thirty-one Tanner stage 4 adolescents were evaluated: testicular volume was measured using a Prader orchidometer, and semen analysis was performed according to standard procedures. Median testicular volume was 20.0ml among Tanner 5 students and 15.0ml in Tanner 4 students in both the right and left testes. No significant differences were found in sperm volume or motility. Median concentration was 66.0 million/ml for Tanner 5 and 47.0 million/ml for Tanner 4 subjects. Morphological patterns showed abnormal forms in 81.9% of Tanner 5 and 93.6% of Tanner 4 adolescents. Oligospermia (sperm concentration < 5 million/ml was observed in 7.3% of Tanner stage 5 and 12.9% of Tanner stage 4 individuals. Azoospermia was observed in 3 students (1.8%, with counts less than 1.0 in 8 students (4.8%. The authors discuss the observed results, analyzing the potential implications arising from biological development and potential environmental exposures.

    Minimally processed vegetables (MPV) may be important vehicles of Salmonella spp. and cause disease. This study aimed at detecting and enumerating Salmonella spp. in MPV marketed in the city of São Paulo, Brazil. A total of 512 samples of MPV packages collected in retail stores were tested for Salmonella spp. and total coliforms and Escherichia coli as indication of the hygienic status. Salmonella spp. was detected in four samples, two using the detection method and two using the counting method, where the results were 8.8 × 10(2) CFU/g and 2.4 × 10(2) CFU/g. The serovars were Salmonella Typhimurium (three samples) and Salmonella enterica subsp. enterica O:47:z4,z23:- (one sample). Fourteen samples (2.7%) presented counts of E. coli above the maximum limit established by the Brazilian regulation for MPV (10(2) CFU/g). Therefore, tightened surveillance and effective intervention strategies are necessary in order to address consumers and governments concerns on safety of MPV. Copyright © 2011 Elsevier Ltd.

    In the last decades considerable attention has been given to technologically enhanced natural occurring radioactive material (TENORM). Within this frame, of particular concern is the phosphate fertilizer industry. Santos Basin, located in Southwest Brazil, Sao Paulo State, comprising Santos and Sao Vicente estuarine system, is considered the most important industrial region of the country. Among the industrial activities present, phosphate fertilizer plants are responsible for the production of 69 millions tons of phosphogypsum waste, which is stockpiled in the surrounding environment. This waste concentrates radionuclides of the natural series originally present in the phosphate rock used as raw material. This study aims to evaluate the environmental impact of such activities in the sediments of the estuarine system. {sup 232} Th and {sup 228} Th concentrations in Santos and San Vicente estuary sediments were determined by Neutron activation analysis and Gamma spectrometry, respectively. {sup 232} Th concentration ranged from 6.5 to 198 Bq kg{sup -1} with mean value of 57 {+-} 39 Bq kg{sup -1}, for 42 samples. {sup 228} Th content varied from 12 to 110 Bq kg{sup -1} with a mean value of 74 {+-} 23 Bq kg{sup -1}, for 18 samples. It can be seen that the amount of {sup 232} Th is higher in the rivers close to the phosphogypsum piles, at least five points were identified as being affected by anthropogenic factor. (Author)

    Full Text Available Abstract: Since ancient times, humans and animals have interacted for different purposes. Animal Assisted Therapy (AAT is used for the assistance and treatment in humans and educational projects where animals are used as co-therapists or co-educators. The use of animals facilitates the process of teaching and learning, and stimulates physical and therapeutic activities. So that knowledge on AAT could be expanded, current study analyzes the opinion of people directly involved in education on AAT implementation as an educational model in early childhood schools in São Paulo, Brazil. Questionnaires were handed out to 10 pedagogical coordinators, 32 teachers, 23 parents and 26 children aged 3-6 years. Results revealed that AAT is not well-known for most interviewees, including pedagogical coordinators, teachers and parents. However, interviewees believe in the benefits of child-pet interactions and are favorable to the implementation of AATs in schools. Projects should be interdisciplinary and must involve professionals from other areas, such as psychologists and veterinarians. Regarding the educational model, interviewees believe in the innovation capacity of AAT and in the possibilities of interdisciplinarity among teachers in the use of animals. Research also demonstrated that children like and support the use of animals in the school.

    This paper presents a preliminary study of the geochemical behavior of metals in river sediments from Parque Estadual da Ilha Anchieta which is located in the north coast of Sao Paulo, Brazil. The Anchieta Island presents many natural ecosystems well preserved without anthropogenic contamination. The sediments were collected in two different points in one of the main rivers of the island. Samples were analyzed by instrumental neutron activation analyses (INAA) which permits the quantification of total concentration of metals (Ba, Co, Cr, Cs, Fe Hf, Rb, Sc, Ta and Zn), rare earth elements (Ce, Eu, La, Lu, Nd, Sm, Tb e Yb), actinides (U and Th) and non metals (As, Br and Sb). Elemental content in the samples had remained relatively constant along the deep of the sample and the changes seemed to be well correlated with the size of the particles in the samples. The precision and the accuracy of the results were evaluated by the analysis of two geological reference materials and data obtained were in good agreement with recommended values. The values obtained for the analyzed elements can be considered the natural concentration of those elements, since Parque Estadual da Ilha Anchieta is preserved from anthropogenic impact. (author)

    Full Text Available After 2003, a new period of expansion of the sugarcane culture began in Brazil. Pre-harvesting burning of sugarcane straw is an agricultural practice that, despite the nuisance for the population and pollution generated, still persisted in over 70% of the municipalities of São Paulo State in 2010. In order to study the distribution of this risk factor, an ecological epidemiological study was conducted associating the rates of deaths and hospital admissions for respiratory diseases, for each municipality in the State, with the exposure to the pre-harvesting burning of sugarcane straw. A Bayesian multivariate regression model, controlled for the possible effects of socioeconomic and climate (temperature, humidity, and rainfall variations, has been used. The effect on health was measured by the standardized mortality and morbidity ratio. The measures of exposure to the pre-harvesting burning used were: percentage of the area of sugarcane harvested with burning, average levels of aerosol, and number of outbreaks of burning. The autocorrelation between data was controlled using a neighborhood matrix. It was observed that the increase in the number of outbreaks of burning was significantly associated with higher rates of hospital admissions for respiratory disease in children under five years old. Pre-harvesting burning of sugarcane effectively imposes risk to population health and therefore it should be eliminated.

  6. Floristic and ecological characterization of habitat types on an inselberg in Minas Gerais, southeastern Brazil

    Directory of Open Access Journals (Sweden)

    Luiza F. A. de Paula

    Full Text Available ABSTRACT Inselbergs are granitic or gneissic rock outcrops, distributed mainly in tropical and subtropical regions. They are considered terrestrial islands because of their strong spatial and ecological isolation, thus harboring a set of distinct plant communities that differ from the surrounding matrix. In Brazil, inselbergs scattered in the Atlantic Forest contain unusually high levels of plant species richness and endemism. This study aimed to inventory species of vascular plants and to describe the main habitat types found on an inselberg located in the state of Minas Gerais, in southeastern Brazil. A total of 89 species of vascular plants were recorded (belonging to 37 families, of which six were new to science. The richest family was Bromeliaceae (10 spp., followed by Cyperaceae (seven spp., Orchidaceae and Poaceae (six spp. each. Life forms were distributed in different proportions between habitats, which suggested distinct microenvironments on the inselberg. In general, habitats under similar environmental stress shared common species and life-form proportions. We argue that floristic inventories are still necessary for the development of conservation strategies and management of the unique vegetation on inselbergs in Brazil.

    In the Ribeira belt, southeastern Brazil, the Precambrian mylonitic fabric mainly formed during the Brasiliano/Pan-African orogeny (640-480 Ma) and was reactivated as fault zones in the Cretaceous and Cenozoic. The reactivation process led to the development of the System of Continental Rifts of southeastern Brazil, from the Paleogene to the Quaternary. We investigated the brittle reactivation of a mylonitic zone, which is part of a major mylonitic belt, Arcádia-Areal. We used geological and geomorphological mapping, resistivity survey, controlled source audiomagnetotelluric survey, and luminescence dating. Our results indicate that this shear zone was reactivated and formed a 15 km long and 2 km wide sedimentary-filled trough, the Rio Santana Graben. It is located on the northwest border of a major structure, the Guanabara Graben, in the State of Rio de Janeiro. The Rio Santana Graben forms an almost entirely fault-bounded, NE-elongated depression that was accommodated entirely within the Arcádia-Areal shear zone. The graben consists of two main depocenters separated by a relay ramp. The graben formed by means of multistage activity of several faults during at least two main periods. The first period formed silicified fault breccia and occurred during alkaline magmatism in the Paleogene. The second formed fault breccia and gouge in shallow conditions and occurred at least until the Quaternary. The NE-trending and NW-dipping Precambrian fabric was reactivated as dip-slip and strike-slip faults. These faults triggered clastic-sediment deposition at least 300 m thick. The upper part of the graben consists of Quaternary alluvial and colluvial sediment fill, which yielded maximum luminescence deposition ages from 49 to 13 ka in the center of the trough. An organic layer at the top of the Quaternary alluvial deposits yielded 14C ages at ˜6000 years BP. The lower part of the graben may be composed of Paleogene to Neogene sedimentary deposits, which occur in other

    The focussed area comprises five major different tectonic terranes separated by faults, which are named Alto Rio Grande Belt, Socorro-Guaxupe Nappe, Sao Roque, Embu and Costeiro Domains. The geological and geochronological history of these terranes show that the metamorphic episodes of crust-forming occurred involving both mantle-derived magmas and reworking of continental material since 3.4 Ga until 600 Ma. The post-tectonic granitic activities occurred within 1000-500 Ma range and in general, the rocks are progressively younger from the Socorro-Guaxupe Nappe (1000-850 Ma) in the NW towards the Costeiro Domain (550 Ma) in the SE. The Sr and Pb isotopic evidences, together with geological and geophysical informations, suggest that the proportions of the rock-forming processes through the geological time are: Archean, 10%; Lower Proterozoic, 10%; Middle Proterozoic, 38%; Late Proterozaic, 42%. Although the Mid and Late Proterozoic time were a period of a large amount of rocks were formed, they were not a major crustforming period, because these rocks are mainly constituted by recycled continental crust material. In our view, at end of the Early Proterozoic time, at least 85% of continetal crust, in this area, has accreted and differentiate. During the Middle and Late Proterozoic the continental crust grew at small rate. (author) [pt

    Full Text Available Some organotin compounds, such as TBT, are endocrine disruptors and harm marine ecosystems. Even after the global ban on organotins, increasing imposex levels have been detected in Stramonita haemastoma analyzed in 2004 and 2011 in some locations at Paraty, a tourist area in southeastern Brazil. The results of this study indicate that particulate and dissolved organic carbon and xenoestrogens might be interfering in this syndrome's development, leading to underestimation of imposex evaluation. Chemical analysis of three mangrove swamp sediments in the area showed the presence of TBT (16.0 - 205.7 ng Sn g-1, DBT (10.1 - 16.4 ng Sn g-1 and MBT (10.1 - 10.2 ng Sn g-1 even at the reference sites. The concentrations of butyltins and the increased incidence of imposexat some stations indicate recent inputs of TBT in the study area due to its illegal use on small vessels.

    The evolution of the Mantiqueira Orogenetic System, Southeastern Brazil, comprises discrete episodes of tectonic collage and docking of remnants of Rodinia break-up in the borders of the Sao Francisco Craton. This system is related to the closure of the Adamastor ocean and assemblage of the western Gondwana super-continent during Neoproterozoic times (ca. 610-530 Ma, Brito Neves et al., 1999; Campos Neto, 2000). This report presents monazite microprobe dating results for metassediments from the Embu Complex, an important lithological unit from the Ribeira Belt, currently included in the Juiz de Fora terrane, a unit added to the Sao Francisco Craton at ca. 600-580 Ma. (Campos Neto, 2000). The age results unravel a main metamorphic episode and related orogeny at ca. 790 Ma and bring new insights concerning the agglutination of Gondwana in this region during the Neoproterozoic (au)

    A new species of Parotocinclus is described from tributaries of rio São João, an Atlantic coastal river of Rio de Janeiro, southeastern Brazil. The new species is distinguished from its congeners by the possession of a triangular patch of dark pigmentation on the anterior portion of the dorsal-fin base, a fully developed adipose fin, complete exposure of the ventral surface of the pectoral girdle, and a distinctive pigmentation pattern of the caudal fin. The caudal fin has a hyaline background with a large black blotch covering its anterior portion, tapering irregularly through distal portions of the ventral lobe with a hyaline rounded area, and a small patch of dark pigmentation on distal portions of the dorsal lobe.

    The global electrical circuit, which maintains a potential of about 280??kV between the earth and the ionosphere, is thought to be driven mainly by thunderstorms and lightning. However, very few in situ measurements of electrical current above thunderstorms have been successfully obtained. In this paper, we present dc to very low frequency electric fields and atmospheric conductivity measured in the stratosphere (30-35??km altitude) above an active thunderstorm in southeastern Brazil. From these measurements, we estimate the mean quasi-static conduction current during the storm period to be 2.5 ?? 1.25??A. Additionally, we examine the transient conduction currents following a large positive cloud-to-ground (+ CG) lightning flash and typical - CG flashes. We find that the majority of the total current is attributed to the quasi-static thundercloud charge, rather than lightning, which supports the classical Wilson model for the global electrical circuit.

    Studies focusing on communities of helminths from Brazilian lizards are increasing, but there are many blanks in the knowledge of parasitic fauna of wild fauna. This lack of knowledge hampers understanding of ecological and parasitological aspects of involved species. Moreover, the majority of research has focused on parasitic fauna of lizards from families Tropiduridae and Scincidae. Only a few studies have looked at lizards from the family Leiosauridae, including some species of Enyalius. This study presents data on the gastrointestinal parasite fauna of Enyalius perditus and their relationships with ecological aspects of hosts in a disturbed Atlantic rainforest area in the state of Minas Gerais, south-eastern Brazil. Two nematode species, Oswaldocruzia burseyi [(Molineidae) and Strongyluris oscari (Heterakidae) were found. Nematode species showed an aggregated distribution in this host population, with O. burseyi being more aggregated than S. oscari. The present study extends the range of occurrence of O. burseyi to the Brazilian continental area.

    Offshore oil exploration creates threats to coastal ecosystems, including increasing urbanization and associated effluent releases. Genotoxicity biomarkers in mussels were determined across a gradient of coastal zone influences of offshore petroleum exploration in southeastern Brazil. Coastal ecosystems such as estuaries, beaches and islands were seasonally monitored for genotoxicity evaluation using the brown mussel Perna perna. The greatest DNA damage (5.2% ± 1.9% tail DNA and 1.5‰  ± 0.8‰ MN) were observed in urban estuaries, while Santana Archipelago showed levels of genotoxicity near zero and is considered a reference site. Mussels from urban and pristine beaches showed intermediate damage levels, but were also influenced by urbanization. Thus, mussel genotoxicity biomarkers greatly indicated the proposed oil exploration and urbanization scenarios that consequently are genetically affecting coastal organisms.

    The genus Adelophryne is composed of diminutive frogs occurring in northern Amazonia and the Atlantic Forest. Herein we describe a new species of Adelophryne found in the leaf litter of primary and secondary forests in the mountainous region of Espírito Santo state, southeastern Brazil. The new species is characterized by its small body size, two phalanges in the finger IV, and a glandular ridge line that runs from the posterior part of eye to the insertion of the forelimb. This species is sensitive to edge effect and conversion of native forest into coffee and Eucalyptus plantations and may be listed as Endangered (EN) under B1ab(iii) criteria of the IUCN Red List.

    Full Text Available Saccopteryx leptura (Schreber, 1774 is reported from two new localities in southeastern Brazil, both in Atlantic forest remains in the state of Rio de Janeiro. Analysisof food material showed that individuals from both localities had preyedon insects in the order Hymenoptera. Cheek contents were available from one specimen, and in this case identification of the food item (flying ants achieved generic level (Pheidole Westwood, 1841. Aspects in the social behavior observed in a colony suggest that the same traits documented in Central American populations (small colonies, monogamic mating system, and retention of young for up to a year in the parental unit may also characterize this species in the southern most part of its range. In both external and craniodental selected measurements, specimens from Rio de Janeiro were close to the upper limits of the ranges known for the species.

    This article reports the results of a nutritional survey among Guarani indigenous children < 5 years of age in the States of Rio de Janeiro and São Paulo, Brazil. Prevalence rates for malnutrition according to various anthropometric indices were 50.4% (low stature-for-age), 7.9% (low weight-for-age), and 0.8% (low weight-for-stature). Prevalence of stunting in Guarani children was 96% higher than for indigenous children in Brazil as a whole (25.7%) and 7.2 times that in children from the general population (7%). Prevalence of anemia was 65.2%, 3.1 times higher than in non-indigenous children (20.9%). The study highlights the high prevalence of chronic undernutrition and anemia in Guarani children and calls attention to serious inequalities in health and nutrition that affect indigenous children in Brazil.

    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 Abstract Background Brazil is currently experiencing a nutrition transition: the displacement of traditional diets with foods high in saturated fat, sodium, and cholesterol and an increase in sedentary lifestyles. Despite these trends, our understanding of child obesity in Brazil is limited. Thus, the aims of this study were (1 to investigate the current prevalence of overweight and obesity in a large sample of children and adolescents living in São Paulo, Brazil, and (2 to identify the lifestyle behaviors associated with an increased risk of obesity in young Brazilians. Methods A total of 3,397 children and adolescents (1,596 male aged 7-18 years were randomly selected from 22 schools in São Paulo, Brazil. Participants were classified as normal weight, overweight, or obese based on international age- and sex-specific body mass index thresholds. Selected sociodemographic, physical activity, and nutrition behaviors were assessed via questionnaire. Results Overall, 19.4% of boys and 16.1% of girls were overweight while 8.9% and 4.3% were obese. Two-way analysis of variance revealed that the prevalence of overweight and obesity was significantly higher in boys and in younger children when compared to girls and older children, respectively (P Conclusions Our results show that obesity in São Paulo children and adolescents has reached a level equivalent to that seen in many developed countries. We have also identified three key modifiable factors related to obesity that may be appropriate targets for future intervention in Brazilian youth: transport mode to school, computer usage, and breakfast consumption.

    Full Text Available In order to assess the molecular epidemiology of HIV-1 in two neighboring cities located near the epicenter of the HIV-1 epidemics in Brazil (Santos and São Paulo, we investigated 83 HIV-1 strains obtained from samples collected in 1995 from intravenous drug users. The V3 through V5 region of the envelope of gp 120 was analyzed by heteroduplex mobility analysis. Of the 95 samples, 12 (12.6% were PCR negative (6 samples from each group; low DNA concentration was the reason for non-amplification in half of these cases. Of the 42 typed cases from São Paulo, 34 (81%, 95% confidence limits 74.9 to 87.0% were B and 8 (19%, 95% confidence limits 12.9 to 25.0% were F, whereas of the 41 typed cases from Santos, 39 (95%, 95% confidence limits 91.6 to 98.4% were B and 2 (5%, 95% confidence limits 1.6 to 8.4% were C. We therefore confirm the relationship between clade F and intravenous drug use in São Paulo, and the presence of clade C in Santos. The fact that different genetic subtypes of HIV-1 are co-circulating indicates a need for continuous surveillance for these subtypes as well as for recombinant viruses in Brazil.

    Full Text Available Seabirds ingest plastic particles floating on the surface of the world's oceans. The birds can ingest plastic particles that they mistakenly identify as prey items. Alternatively, plastics can be taken up in the stomach contents of prey species. Plastic is often passed from parents to chicks in regurgitated food. In this study, individual petrels and albatrosses brought in by the tide onto Ilha Comprida beach between January 2000 and December 2002 were collected. Ilha Comprida, a barrier island in southern São Paulo, Brazil, was traversed by car along a transect of 70 kilometers. A total of 110 birds of 10 species were collected and 64.54% had plastic particles in their stomach. Frequencies of occurrence were Macronectes giganteus (64.28%, Thalassarche melanophrys (73.07%, Thalassarche chlororhinchos (44.44%, Puffinus puffinus (85.71%, Puffinus gravis (7.41%, Puffinus griseus (63.63%, Fumarus glacialoides (33.33%, Daption capensis (75%, Pachyptila belcheri (33.33%, Procellaria aequinoctialis (25%. These results demonstrated the extent of contamination with plastic and the possible harmful effects on seabirds.As aves marinhas ingerem partículas plásticas que ficam flutuando na superfície dos oceanos.

    Full Text Available A clinical trial pilot study, double-blinded, randomized, and controlled with a placebo to assess the effectiveness of oral doxycycline (200 mg, single dose in preventing leptospirosis after high exposure to potentially contamined water was performed in São Paulo, SP, Brazil. Confirmed cases were defined as those with leptospira IgM antibody and symptoms; asymptomatic cases were those presenting with IgM antibodies but no symptoms; and suspected cases were individuals with symptoms but no IgM antibody. Forty subjects were given doxycycline and 42 were given placebo. In the drug-treated group there were 2 confirmed cases, 11 asymptomatic cases, and 6 suspected cases. In the placebo group there were 5 confirmed, 6 symptomatic, and 5 suspected cases. Even though we found a protective association of doxycycline for confirmed leptospirosis cases (RR = 2.3 and seroconversion only (RR = 2.0, the association was not statistically significant because of the small number of individuals enrolled in this pilot study. We observed that the 22% of the volunteers already had IgM antibodies to leptospirosis at the first sampling. Finally, the attack rate to confirmed, asymptomatic, and suspected cases of Leptospirosis was 8.5%, 22%, and 13%, respectively, in this population.Um ensaio clínico, duplo-cego, ao acaso, e controlado com placebo para aferir a eficácia da doxiciclina (200 mg, dose única em prevenir leptospirose após exposição de alto risco com água potencialmente contaminada foi realizado em São Paulo, SP, Brasil.

    The metropolis of Sao Paulo, with its 7940 Km² and over 20 million inhabitants, is increasingly being consolidated with disregard for the dynamics of its fluvial systems and natural limitations imposed by fluvial terraces, floodplains and slopes. Events such as floods and flash floods became particularly persistent mainly in socially and environmentally vulnerable areas. The Aricanduva River basin was selected as the ideal area for the development of the flood hazard analysis since it presents the main geological and geomorphological features found in the urban site. According to studies carried out by Anthropic Geomorphology approach in São Paulo, to study this phenomenon is necessary to take into account the original hydromorphological systems and its functional conditions, as well as in which dimensions the Anthropic factor changes the balance between the main variables of surface processes. Considering those principles, an alternative model of geographical data was proposed and enabled to identify the role of different driving forces in terms of spatial conditioning of certain flood events. Spatial relationships between different variables, such as anthropogenic and original morphology, were analyzed for that purpose in addition to climate data. The surface hydrodynamic tendency spatial model conceived for this study takes as key variables: 1- The land use present at the observed date combined with the predominant lithological group, represented by a value ranging 0-100, based on indexes of the National Soil Conservation Service (NSCS-USA) and the Hydraulic Technology Center Foundation (FCTH-Brazil) to determine the resulting balance of runoff/infiltration. 2- The original slope, applying thresholds from which it's possible to determine greater tendency for runoff (in percents). 3- The minimal features of relief, combining the curvature of surface in plant and profile. Those three key variables were combined in a Geographic Information System in a series of

    2015-06-01

    The urban population of South America has grown at 1.05%/yr, greater urbanization increasing problems related to air pollution. In most large cities in South America, there has been no continuous long-term measurement of regulated pollutants. One exception is São Paulo, Brazil, where an air quality monitoring network has been in place since the 1970s. In this paper, we used an air quality-based approach to determine pollutant trends for emissions of carbon monoxide (CO), nitrogen oxides (NOx), ozone (O3), and coarse particulate matter (PM10), mostly from mobile sources, in the Metropolitan Region of São Paulo for the 2000-2013 period. Mobile sources included light-duty vehicles (LDVs, comprising gasoline- or ethanol-powered cars and motorcycles) and heavy-duty vehicles (HDVs, comprising diesel-powered trucks and buses). Pollutant concentrations for mobile source emissions were measured and correlated with fuel sales by the emission factors. Over the 2000-2013 period, concentrations of NOx, CO, and PM10 decreased by 0.65, 0.37, and 0.71% month-1, respectively, whereas sales of gasoline, ethanol, and diesel increased by 0.26, 1.96, and 0.38% month-1, respectively. LDVs were the major mobile source of CO, whereas LDVs were the major source of NOx and PM10. Increases in fuel sales and in the corresponding traffic volume were partially offset by decreases in pollutant concentrations. Between 2000 and 2013, there was a sharp (-5 ppb month-1) decrease in the concentrations of LDV-emitted CO, together with (less dramatic) decreases in the concentrations of HDV-emitted NOx and PM10 (-0.25 and -0.09 ppb month-1, respectively). Variability was greater for HDV-emitted NOx and PM10 (R = -0.47 and -0.41, respectively) than for LDV-emitted CO (R = -0.72). We draw the following conclusions: the observed concentrations of LDV-emitted CO decreased at a sharper rate than did those of HDV-emitted NOx and PM10; mobile source contributions to O3 formation varied significantly, LDVs

    The Guarapiranga Reservoir, located in Sao Paulo metropolitan region, Brazil, is responsible for supplying about 20% of the entire population's water needs of this region or approximately 3.7 million people. However, this system has shown significant degradation in water quality, due to untreated domestic sewage and industrial effluents. In this study sediment samples were collected at five points along the reservoir and total concentration of some major (Fe, K and Na), trace (As, Ba, Br, Co, Cr, Cs, Hf, Hg, Rb, Sb, Sc, Ta, Tb, Th, U, V and Zn) and rare earth (Ce, Eu, La, Lu, Nd, Sm, Tb and Yb) elements were determined by instrumental neutron activation analysis (INAA). By inductively coupled plasma optical emission spectrometry (ICP OES) the concentrations of Al, Ba, Be, Ca, Co, Cr, Cu, Fe, K, Li, Mg, Mn, Na, Ni, Pb, Ti, V e Zn were determined after digestion procedure following US EPA 3051 methodology. The concentrations of metals Cd and Pb were determined by graphite furnace atomic absorption spectrometry (GFAAS) and total Hg by cold vapor atomic absorption spectrometry (CVAAS). Methodology validation according to precision and accuracy was performed by reference materials analyses for the three different analytical techniques used. Multielemental results obtained by INAA were compared to NASC (North American Shale Composite), Upper Continental Crust (UCC) and soil from Guarapiranga park values. The Enrichment Factor (EF) and Geo accumulation Index (Igeo) were also evaluated for these data. Metal concentration results by ICP OES and AAS in the samples were compared to the TEL and PEL oriented values established by the Canadian Council of Ministers of the Environment and also adopted by CETESB (Environmental Protection Agency of the Sao Paulo State). The results were also compared to regional reference values (VRR) of limnic sediments from the Alto Tiete Basin. From these data an assessment of metal and trace element accumulated in the sediments from the

The measurements were sampled during 24 hours using a Personal Cascade Impactor (SKC Cat No. 225-370), which the following aerodynamic diameters: 10.0 - 2.5 (A); 1.0 - 2.5 (B); 0.50 - 1.0 (C); 0.25 - 0.50 (D), and < 0.25 μm (E). Together the impactor, there is a Leland Legacy pump (SKC Cat No. 100-3002) with a flow of 9L/min. It was analyzed 56 households with average values of PM10 and PM2.5 of 30.7 and 23.4 μg/m3, respectively. On average, 76% of PM10 consists of PM2.5, percentage higher than the outdoor environment (60% - CETESB), and 43% of the PM2.5 consists of PM smaller than 0.25 μm. Among all households, there was no exceedance of thresholds national standards PM10 (120 μg/m3) and PM2.5 (60 μg/m3). However, 10.7% of residences exceeded the PM10 threshold of the World Health Organization (50 μg/m3) and 39.2% for PM2.5 (20 μg/m3). The cluster analysis grouped the measures in the houses in four profiles. In three of them were greater amount of mass in ultrafine particles (E), followed by coarse particles (A) with the minimum in C level. The maximum in E may be due to the high contribution vehicular and secondary aerosol outdoor environment. The secondary maximum in A may be due to particles ressuspension and also arising from outdoors. These three groups differ only by the amount of PM measured in the households; they represent high, medium and low PM concentrations. The fourth group has average concentrations, but it presents a different profile because its maximum is in the D rather than E. All data will be analyzed concerning the possible sources.

    The aim of this study was to compare the prevalence of sleep habits and complaints and to estimate the secular trends through three population-based surveys carried out in 1987, 1995, and 2007 in the general adult population of the city of Sao Paulo, Brazil. Surveys were performed using the same three-stage cluster-sampling technique in three consecutive decades to obtain representative samples of the inhabitants of Sao Paulo with respect to gender, age (20-80 years), and socio-economic status. Sample sizes were 1000 volunteers in 1987 and 1995 surveys and 1101 in a 2007 survey. In each survey, the UNIFESP Sleep Questionnaire was administered face-to-face in each household selected. For 1987, 1995, and 2007, respectively, difficulty initiating sleep (weighted frequency %; 95% CI) [(13.9; 11.9-16.2), (19.15; 16.8-21.6), and (25.0; 22.5-27.8)], difficulty maintaining sleep [(15.8; 13.7-18.2), (27.6; 24.9-30.4), and (36.5; 33.5-39.5)], and early morning awakening [(10.6; 8.8-12.7), (14.2; 12.2-16.5), and (26.7; 24-29.6)] increased in the general population over time, mostly in women. Habitual snoring was the most commonly reported complaint across decades and was more prevalent in men. There was no statistically significant difference in snoring complaints between 1987 (21.5; 19.1-24.2) and 1995 (19.0; 16.7-21.6), but a significant increase was noted in 2007 (41.7; 38.6-44.8). Nightmares, bruxism, leg cramps, and somnambulism complaints were significantly higher in 2007 compared to 1987 and 1995. All were more frequent in women. This is the first study comparing sleep complaints in probabilistic population-based samples from the same metropolitan area, using the same methodology across three consecutive decades. Clear trends of increasing sleep complaints were observed, which increased faster between 1995 and 2007 than from 1987 to 1995. These secular trends should be considered a relevant public health issue and support the need for development of health care and

    Carbonaceous aerosols play an important role in air quality, human health and global climate change. Black Carbon (BC) can be considered the most efficient light absorber in the visible spectrum and is mainly found in the fine fraction of aerosol. Typically is emitted by incomplete combustion of fossil fuels related to traffic, industrial processes and biomass burning. São Paulo Metropolitan Area (SPMA) with more than 19 million inhabitants, 7 million vehicles, as well as the major industrial and technological park of the country, has high concentrations of air pollutants, especially in the winter and vehicles are considered the principal source of particles emitted to the atmosphere. Since November 2014, Black Carbon and PM2.5 are being monitored using a MAAP (Multi Angle Absorption Photometer) Thermo 5012 and a Dust Trak DRX-8533 TSI in the East Campus of University of São Paulo, close to important highways and also to the largest airport of Brazil (Guarulhos Airport). Average BC concentration was 1.7 μg/m3 with some peaks above 17.0 μg/m3 and for PM2.5 average was 10.2 μg/m3. Particle concentrations reached values greater than the air quality standard (60 μg/m3) in the winter months. Winds coming from the East direction predominate. Traffic restrictions to heavy duty vehicles in the road-rings next to the sampling site during some hours of the day are the responsible for the daily BC and PM2.5 behavior (figure below), where high concentrations occur early in the morning and late at night, when heavy diesel vehicles are released for transit. Seasonal variations are different for BC and PM2.5 due to local sources of BC and meteorological conditions that have more influence on the particles. The weekly variation indicates that concentrations are lower on Sundays and higher from Tuesday to Thursday. Emission factors for BC were calculated based on traffic information.

    The portions of the Precambrian Costeiro Complex adjacent to the Sao Sebastiao Channel (Sao Paulo State, Brazil) are crosscut by mafic dykes of basic to intermediate composition, lamprophyres and trachytes. The former have been correlated with the basalts of the Parana Basin, while the lamprophyres are expressions of an alkaline magmatism different from the one that happened approximately 80 Ma ago in the Sao Sebastiao, Buzios, Vitoria and Montao de Trigo islands, where more acid terms predominate with associated trachytes and rare phonolites. The basic-ultrabasic lamprophyric magmatism is widespread along the Sao Paulo and Rio de Janeiro coasts; they are independent from and most likely older than the stocks and alkaline massifs.

    Full Text Available The largest area of preserved Atlantic forest is located in the southern portion of Brazil. The region of Paranapiacaba is depicted in Brazilian zoological studies as one of the first and most intensely sampled areas of the state of São Paulo.We provide a concise list of reptiles and amphibians from the Paranapiacaba Municipal Park. It represents the first comprehensive survey of the group in the area. We recorded 136 species of reptiles and amphibians from field surveys, museum collections and the literature. The anuran diversity of Paranapiacaba is greater than that of Estação Ecológica de Boracéia, which has been considered the most distinctive areas in São Paulo in terms of amphibian diversity. The rich history of herpetological research in the region, including the occurrence of the two most threatened species in Brazil, converts the area to an important conservation landmark for the Brazilian herpetofauna.

  14. Natural radionuclides and 137Cs in commercialized edible mushrooms in Sao Paulo-Brazil

    Castro, Lilian Pavanelli de

    2008-01-01

    Artificial and natural radionuclides are commonly found in several compartments of the earth's crust. Some mushroom species have a high capacity to absorb radionuclides and toxic elements from the soil. Diet is considered as one of the main routes of radioactive contamination. Therefore, radioactivity measurements in the environment and in food are extremely important to monitor the radiation levels that human can be exposed to either directly or indirectly. Environmental bio monitoring has demonstrated that diverse organisms such as crustaceans, fish and mushrooms are useful when evaluating both the contamination and the quality of the ecosystems. There are actually several radionuclides that can be accumulated in mushrooms, including 40 K, 137 Cs, 232 Th and 238 U. There are few studies in the Southern hemisphere countries, on the natural and artificial radioactivity levels in mushrooms. The present study evaluated 40 K, 137 Cs, 232 Th and 238 U in commercialized edible mushrooms in the state of Sao Paulo, Brazil. The edible mushroom samples were acquired in different commercial establishments in the Sao Paulo metropolitan region, specifically in Municipal Markets. Some samples were acquired directly from producers located in the cities of Mogi das Cruzes, Mirandopolis, Suzano and Juquitiba. About 400g were collected for each edible mushroom species, which included Agaricus sp, Pleurotus sp and Lentinula sp species. All the samples were prepared and stored in polyethylene bottles for approximately 35 days, so that secular equilibrium could be established before counting. The 40 K, 137 Cs, 232 Th and 238 U gamma activities were measured by gamma spectrometry. The equipment consisted of a Hyper pure Germanium detector connected to an electronic system. The detector efficiency was obtained from measurements of reference materials: IAEA-300, IAEA-327 and IAEA-375. The results for the specific activities in edible mushrooms samples ranged fi-om 461 to 1535 Bq kg -1

    To describe the incidence of tuberculosis among inmates of the municipal prison system in the city of Campinas, State of São Paulo, Brazil, from 1993 through 2000. A retrospective study was carried out of the number of cases of tuberculosis that were notified among inmates over the study period. This involved reviewing data from a total of 4,293 inmates who were held in the four prisons that comprise Campinas' municipal prison system. Data were obtained from the tuberculosis database belonging to the Department of Social and Preventive Medicine of the School of Medical Sciences at the State University of Campinas. The incidence of tuberculosis peaked in 1994 (1,397.62 cases per 100,000) and was lowest in 1999 (559.04 cases per 100,000). Most cases of tuberculosis occurred in inmates in the 25 to 34 year age group (62.6%). Acquired immunodeficiency syndrome (AIDS) was the disease most commonly associated with tuberculosis (49.9%), which was most often pulmonary in type (91.9%), with positive sputum smears in 70.3% of the inmates tested. Most inmates had not received treatment before (75.4%). The treatment dropout rate reached 49%, and a cure was achieved in only 20.8% of the cases notified over the study period. The incidence of tuberculosis observed in this study was moderate when compared to incidence rates found in other studies of prison inmates, but this could be due to underreporting. The frequency of treatment failure noted was low, since patients who were treated under supervision showed good adherence and were cured in the majority of cases. However, the high treatment dropout rate seen in the study is alarming because it could facilitate the spread of drug resistant strains of Mycobacterium tuberculosis to the community at large. Controlling tuberculosis among prison inmates should be part of routine interventions aimed at eliminating this disease from the community and at preventing resistance to antituberculosis therapy.

    Full Text Available Santos Harbor Area (SHA in Sao Paulo Coastline (Brazil is the most important marine cargo transfer terminal in the Southern Hemisphere. A long term relative tidal level variability assessment shows a consistent response to relative sea level rise. A wave data base Wave Watch III was compared with a long term wave data-base generated by the ERA40-ECMWF (2003, both local validated. The current bed level of SHA Outer Channel is -15.00 m (Chart Datum or, in abbreviation, CD, maintained by dredging. According to the cargo throughput forecast, in 2025, the Access Channel will have to be deepened to level of -17.00 m. The feasibility of that choice is discussed from a technical, economical and conceptual navigation point of view in that context. A data set found from a scale model of the whole area of Santos Bay, Estuary and nearby beaches, showed the impact of maritime climate changes upon the coastal area. In the previous researches developed by the authors, it was demonstrated that the wave climate, the tides and tidal currents affect harbor and coastal structures maintenance, beaches stability, tidal inlet, sediment transport, saline intrusion and wetlands. Considering the increasing of the sea hazards and the high values of the infrastructures in that coastline, it is necessary to mitigate the risks. Hence, based on the results obtained by the authors, are highlighted guidelines strategies suggested for Access Channels dimensions, wharves free-board, jetties dimensions, dredging rates, rigid and flexible littoral defenses and land protection against flooding (including wetlands.

    Identify the factors associated with the age-standardised breast cancer mortality rate in the municipalities of State of São Paulo (SSP), Brazil, in the period from 2006 to 2012. Ecological study of the breast cancer mortality rate standardised by age, as the dependent variable, having each of the 645 municipalities in the SSP as the unit of analysis. The female resident population aged 15 years or older, by age group and municipality, in 2009 (mid-term), obtained from public dataset (Informatics Department of the Unified Health System). Women 15 years or older who died of breast cancer in the SSP were selected for the calculation of the breast cancer mortality rate, according to the municipality and age group, from 2006 to 2012. Mortality rates for each municipality calculated by the direct standardisation method, using the age structure of the population of SSP in 2009 as the standard. In the final linear regression model, breast cancer mortality, in the municipal level, was directly associated with rates of nulliparity (p<0.0001), mammography (p<0.0001) and private healthcare (p=0.006). The findings that mammography ratio was associated, in the municipal level, with increased mortality add to the evidence of a probable overestimation of benefits and underestimation of risks associated with this form of screening. The same paradoxical trend of increased mortality with screening was found in recent individual-level studies, indicating the need to expand informed choice for patients, primary prevention actions and individualised screening. Additional studies should be conducted to explore if there is a causality link in this association. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    The mullet (Mugilidae) is a fish caught in large quantities in brackish and marine waters of the southern Brazilian coast, which in consequence of its raw consumption as ''sashimi'', a typical Japanese dish, has led to ten cases of human infection by Phagicola longa in Sao Paulo, Brazil. The mullet acts as a second intermediate host for the parasite, as in human heterophyiasis in the Near and Far East. In order to control these infections under commercial storage conditions and in raw consumption, the radiolysis of P. longa was studied in three mullet species - the silver mullet (Mugil curema), the grey mullet (M. platanus) and the ''paratipema'' (Mugil sp.) -subjected to ionization ranging from 1.0 to 10.0 kGy (2.21 kGy/h). It was observed that 1.0 and 2.0 kGy caused a motility decrease in silver mullet parasites from 100% to 15% and 17%, and that doses of 4.0 and 10.0 kGy caused metacercaria inviability. The parasite motility decreased in the grey mullet treated with doses of 2.0, 2.5, 3.0 and 3.5 kGy, from 56% to 31%, 9%, 18% and 5%, respectively, 4.0 kGy tending to be the control dose for P. Longa. This dose also controls other metacercaria found in the ''parati-pema'', without changing the odor, color or appearance of the treated mullet. (author).

    It is of universal knowledge that the soil, a basic natural resource, is renewable only if conserved or used correctly(Primavesi, 2002). It is salient for Araújo et al. (2007) that the establishment of index of soil quality is an important tool in the functions of control, supervision and monitoring of areas for environmental protection. The objective of this study was to compare the quality of the soil by means of a comparative diagram in different soil uses in permanent preservation areas (APP). The study was conducted in areas near the Ribeira de Iguape river in the city of Registro - São Paulo - Brazil, belonging to the Atlantic Forest domain, a Haplic Cambisol. The following uses of the soil had been evaluated: a) banana culture (CBAN) without agricultural traffic of machines; b) degraded pasture (PDEG) with extensive system predominantly Brachiaria decumbens L. c) use silvopastoral (MPIs), consisted in a kills with a traffic free for the animals, and d) native vegetation (MNAT), proposed in this study as a reference area.The following physical indicators were analyzed: bulk density (BD), total soil porosity (TP), macroporosity (Ma), microporosity (Mi), water dispersible clay (ADA), flocculation index (FI), preconsolidation pressure (PP), soil shear strength (SS), soil resistance to penetration (RP). To construct the comparative diagram the values for each attribute of the soil in each land use were related to the values of the native forest. It was feasible to use the comparative model in the qualitative evaluation of soil use, allowing separate environments under different uses. According to the comparative diagram of banana culture is the use that most negatively impacts the physical and mechanical soil due to the smaller size of the lower polygon.

    2000-06-01

    Full Text Available The spatial variability of strongly weathered soils under sugarcane and soybean/wheat rotation was quantitatively assessed on 33 fields in two regions in São Paulo State, Brazil: Araras (15 fields with sugarcane and Assis (11 fields with sugarcane and seven fields with soybean/wheat rotation. Statistical methods used were: nested analysis of variance (for 11 fields, semivariance analysis and analysis of variance within and between fields. Spatial levels from 50 m to several km were analyzed. Results are discussed with reference to a previously published study carried out in the surroundings of Passo Fundo (RS. Similar variability patterns were found for clay content, organic C content and cation exchange capacity. The fields studied are quite homogeneous with respect to these relatively stable soil characteristics. Spatial variability of other characteristics (resin extractable P, pH, base- and Al-saturation and also soil colour, varies with region and, or land use management. Soil management for sugarcane seems to have induced modifications to greater depths than for soybean/wheat rotation. Surface layers of soils under soybean/wheat present relatively little variation, apparently as a result of very intensive soil management. The major part of within-field variation occurs at short distances (< 50 m in all study areas. Hence, little extra information would be gained by increasing sampling density from, say, 1/km² to 1/50 m². For many purposes, the soils in the study regions can be mapped with the same observation density, but residual variance will not be the same in all areas. Bulk sampling may help to reveal spatial patterns between 50 and 1.000 m.

  1. Landscape, Environmental and Social Predictors of Hantavirus Risk in São Paulo, Brazil.

    Directory of Open Access Journals (Sweden)

    Paula Ribeiro Prist

    Full Text Available Hantavirus Pulmonary Syndrome (HPS is a disease caused by Hantavirus, which are negative-sense RNA viruses in the family Bunyaviridae that are highly virulent to humans. Numerous factors modify risk of Hantavirus transmission and consequent HPS risk. Human-driven landscape change can foster transmission risk by increasing numbers of habitat generalist rodent species that serve as the principal reservoir host. Climate can also affect rodent population dynamics and Hantavirus survival, and a number of social factors can influence probability of HPS transmission to humans. Evaluating contributions of these factors to HPS risk may enable predictions of future outbreaks, and is critical to development of effective public health strategies. Here we rely on a Bayesian model to quantify associations between annual HPS incidence across the state of São Paulo, Brazil (1993-2012 and climate variables (annual precipitation, annual mean temperature, landscape structure metrics (proportion of native habitat cover, number of forest fragments, proportion of area planted with sugarcane, and social factors (number of men older than 14 years and Human Development Index. We built separate models for the main two biomes of the state (cerrado and Atlantic forest. In both biomes Hantavirus risk increased with proportion of land cultivated for sugarcane and HDI, but proportion of forest cover, annual mean temperature, and population at risk also showed positive relationships in the Atlantic forest. Our analysis provides the first evidence that social, landscape, and climate factors are associated with HPS incidence in the Neotropics. Our risk map can be used to support the adoption of preventive measures and optimize the allocation of resources to avoid disease propagation, especially in municipalities that show medium to high HPS risk (> 5% of risk, and aimed at sugarcane workers, minimizing the risk of future HPS outbreaks.

    Full Text Available An increase in daily mortality from myocardial infarction has been observed in association with meteorological factors and air pollution in several cities in the world, mainly in the northern hemisphere. The objective of the present study was to analyze the independent effects of environmental variables on daily counts of death from myocardial infarction in a subtropical region in South America. We used the robust Poisson regression to investigate associations between weather (temperature, humidity and barometric pressure, air pollution (sulfur dioxide, carbon monoxide, and inhalable particulate, and the daily death counts attributed to myocardial infarction in the city of São Paulo in Brazil, where 12,007 fatal events were observed from 1996 to 1998. The model was adjusted in a linear fashion for relative humidity and day-of-week, while nonparametric smoothing factors were used for seasonal trend and temperature. We found a significant association of daily temperature with deaths due to myocardial infarction (P < 0.001, with the lowest mortality being observed at temperatures between 21.6 and 22.6ºC. Relative humidity appeared to exert a protective effect. Sulfur dioxide concentrations correlated linearly with myocardial infarction deaths, increasing the number of fatal events by 3.4% (relative risk of 1.03; 95% confidence interval = 1.02-1.05 for each 10 µg/m³ increase. In conclusion, this study provides evidence of important associations between daily temperature and air pollution and mortality from myocardial infarction in a subtropical region, even after a comprehensive control for confounding factors.

    Phurcalite has been found filling fractures in the tourmaline-bearing granitic pegmatite of Perus, in the north-west part of Sao Paulo city, Brazil. It forms aggregates of radiating euhedral crystals up to 5 mm in length. The crystals are bright yellow, transparent and display vitreous to adamantine lustre. Its streak is pale yellow. Phurcalite is brittle, with a conchoidal fracture, and non-fluorescent. The crystal structure of phurcalite has been solves by single-crystal x-ray diffraction methods and refined to R = 3.8% using 2065 observed [I > 3σ(I)] reflections. The structure consists of [(U O 2 ) 3 O 2 (P O 4 ) 2 4n- ] n layers, parallel to (010), connected by Ca 2+ ions and H 2 O. The coordination polyhedra are: for U(1) hexagonal bi pyramid; for U(2) and U(3) pentagonal bi pyramids; for Ca(4) and Ca(5) capped trigonal prism and triangulated dodecahedron, respectively; and for P(6) and P(7) tetrahedra. As a consequence of this work, the molecular formula of phurcalite previously reported as Ca 2 (U O 2 ) 3 (P O 4 ) 2 (OH) 4 .4 H 2 O must be changed to Ca 2 (U O 2 ) 3 O 2 (P O 4 ) 2 .7 H 2 O. Other secondary uranium minerals associated with Perus phurcalite are autunite, torbernite, meta-autunite, meta-torbernite, chernikovite, meta-uranocircite I, phosphuranylite, uranophane-alpha, uranophane-beta, haiweeite, barian week site and perhaps also bassetite, meta-tyuyamunite and meta-haiweeite. Opal, tridymite, cristobalite, secondary quartz, saponite and rhodochrosite occur associated to the uranium minerals. (author)

    Full Text Available A new species of Masteria L. Koch, 1873 from iron ore caves at Caeté and Santa Bárbara, state of Minas Gerais, Brazil, Masteria emboaba sp. nov., is described. It was collected inside caves and in the litter of nearby dry forests. It is the first masteriine species described from southeastern Brazil and the second masteriine species for the country. The new species is the only known Masteria with only two eyes. Additionally, the male of M. emboaba sp. nov. has only two regular, thin spines at the apex of tibia I, lacking the tibial apophysis found in most other Masteria species. The only other described Masteria species that has spines in the place of tibial apophysis is M. aimeae (Alayón, 1995 from Cuba; however, the last species has a longer and sinuous embolus, contrasting the embolus of M. emboaba sp. nov., which is much smaller, less sinuous and transversally placed. The only other described Brazilian species, M. manauara Bertani, Cruz & Oliveira, 2013, has a double tibial apophysis, with both ends tipped by a strong, short spine, and a very long embolus, parallel to the bulb.

    Full Text Available Defense behavior of the endemic tropidurid lizard Eurolophosaurus nanuzae was studied in an area of rocky outcrops at Serra do Cipó, Minas Gerais State, southeastern Brazil. Tail loss aspects of this species were also studied in lizards from three populations (Diamantina, Serra do Cipó, and Serro, Minas Gerais State, Brazil. Lizards relied primarily on crypsis to avoid detection by predators. Secondary defense strategies involved a complex set of behaviors. Mean maximum distance of flight was 1.68 ± 1.70 m. When captured,individuals attempted to flee, lifted the tail, produced distress calls, discharged the cloacal contents, waived their tails, and bit. Frequency of tail autotomy was 13.2% (n = 53 in Diamantina, 11.9% (n = 42 in Serra do Cipó, and 4.1% (n = 49 in Serro. Tail autotomy frequency did not differ among the three populations (X2 = 3.3, DF =2, p = 0.19. Tail autotomy did not vary between the years of the study (X2 = 1.32, p = 0.35 and did not differ between males and females among the studied populations.

    The use of arthropods for monitoring habitat changes has grown widely in the last decades. In Brazil, however, most of the studies in restored areas have involved only vegetation changes. The present study aimed at investigating recolonization patterns of epigeic arthropods in recently restored sites of semideciduous forests in southeastern Brazil. We compared the community structure of adjoining sites 5, 17, 29 and 36 months old with that at a nearby forest remnant (reference site). We also determined the most abundant species and looked for ecological indicator species of each site age. Arthropods were sampled using pitfall traps, and their assemblages were described and compared with multi- and univariate statistical methods. Species abundance and richness equivalent to the reference site were reached at five months after planting, however species composition was very distinctive not only in relation to the reference site, but also among restored sites. Some of the main species found in this restoration stage are common in agroecosystems or cerrado vegetation. Nevertheless, there was a clear trend of arthropod fauna in restored sites moving toward the fauna in the forest remnant over time. Our results also highlighted ants and termites because of their abundance and ants because of their high value as ecological indicators of restoration age.

    Full Text Available In recent decades, the elderly population in Brazil has grown rapidly, as has concern for the health of this population. Institutionalization in nursing homes has appeared as an alternative form of health care for frail elderly that live alone. The present study evaluated the pharmacotherapy and inappropriate drug prescriptions for institutionalized elderly patients living in long-term institutions in southeastern Brazil. This research was conducted at five institutions with a total sample of 151 individuals aged at least 60 years. Databases were used to identify drug interactions, defined daily dose and inappropriate prescriptions. The prevalence of drug intake among the elderly was 95.36%, and there were an average of 3.31 ± 1.80 drug prescriptions per individual. Based on Beers criteria, the prevalence of inappropriate prescriptions was 25.83%. In addition, 70.2% of prescriptions were prescribed at a higher dosage than the defined daily dose (ATC/WHO. Potential drug interactions were identified for 54.11% of prescriptions; 81.42% of these were of moderate severity. The main inappropriate drugs were prescribed for cardiovascular and nervous system problems. Institutionalized elderly individuals presented a high consumption and misuse of medications, requiring professional intervention to monitor prescriptions and improve the quality of service for this population.

    Full Text Available Bat species richness in Neotropical localities is generally higher than that of any other group of mammals, and surveys of local bat assemblages may provide useful data for conservation management plans. Although the bat fauna of the Rio de Janeiro state is currently one of the best known in Brazil, there are several localities not adequately surveyed yet, and most of them are in the mountainous regions and in the northern portion of the state. From January 2008 to November 2009, we conducted surveys of bats in three localities in the state of Rio de Janeiro (municipalities of Varre-Sai, Sumidouro, and Cantagalo, and our fieldwork constitutes the first assessment of the bat assemblages of these localities. Surveys were conducted using mist nets in four different habitat types in each locality (forest interior, forest edge, riparian forest, and open areas [pastures]. We captured a total of 148 individuals in 17 species, 14 genera and 3 families. Among them, 11 species were recorded in Sumidouro, seven in Cantagalo, and nine in Varre-Sai. Although species richness was low compared with previous surveys in other close localities, we recorded species that have been rarely sampled in Southeastern Brazil (e.g., Macrophyllum macrophyllum [Phyllostomidae]. The results reinforce the importance of sampling different habitats in short surveys to improve the number of species registered.

    Full Text Available OBJECTIVE: To determine the prevalence of psychiatric disorders in the prison population in the State of São Paulo, Brazil. METHODS: Through stratified random sampling, 1.192 men and 617 women prisoners were evaluated for the presence of psychiatric disorders by the Composite International Diagnostic Interview, 2.1 version, according to definitions and criteria of International Classification of Diseases (ICD-10. The prevalence estimates of mental disorders and their respective 95% confidence intervals were calculated and adjusted for sample design through complex sample analysis. RESULTS: Lifetime and 12-month prevalence rates differed between genders. Lifetime and 12-month prevalence of any mental disorder was, respectively, 68.9% and 39.2% among women, and 56.1% and 22.1% among men. Lifetime and 12-month prevalence of anxious-phobic disorders was, respectively, 50% and 27.7% among women and 35.3% and 13.6% among men, of affective disorders was 40% and 21% among women and 20.8% and 9.9% among men, and of drug-related disorders was 25.2% and 1.6% among women and 26.5% and 1.3% among men. For severe mental disorders (psychotic, bipolar disorders, and severe depression, the lifetime and 12-month prevalence rates were, respectively, 25.8% and 14.7% among women, and 12.3% and 6.3% among men. CONCLUSIONS: This is the first large-scale epidemiological study performed with the prison population in Brazil, revealed high rates of psychiatric disorders among men and women. Many similarities, as well as some differences, were found between our results and those of studies conducted in other countries. The differences observed are more likely due to the peculiarities of the prison systems in each country than to the diagnostic criteria adopted in the studies. This fact reinforces the importance of conducting such studies as part of planning and development of appropriate policies for the particular mental health needs of specific prison populations.

    Numerical analyses of modern foraminiferal abundance and environmental data from the Bertioga Channel (Sa??o Paulo, Brazil) reveal multiple biofacies within an overall paralic setting. Despite its fisheries, mariculture and attraction to tourists, the environmental state of Bertioga Channel remains poorly studied. The present investigation is an attempt to partly fill this gap; the parameters examined include depth, salinity, temperature, organic carbon, sulfur content and bottom sediment type. Muddy sediments with high organic carbon content derived from land drainage are found in the inner parts of the channel, whereas sandy sediment dominates the areas adjacent to the Atlantic Ocean. In the eastern entrance to the channel, sandy sediment contain species of Rotaliida from Facies 1 (including Elphidium discoidale, Elphidium poeyanum, Hanzawaia boueana, Pararotalia cananeiaensis and Nonionella atlantica), reflecting normal marine salinity. Sediments with high percentages of silt and clay in polyhaline and eurybaline environments of the eastern part and Itapanhau?? River contain Facies 2, which includes Ammonia beccarii and Pararotalia cananeiaensis. In the western entrance and central, western and eastern parts, where salinities vary from 18 to 30 psu and the sediments contain both low and high organic carbon, the foraminifera from Facies 3 are dominated by Quinqueloculina milletti, Arenoparrella mexicana, Pararotalia cananeiaensis, Ammonia beccarii, Buliminella elegantissima, Elphidium sp., Elphidium excavatum, Elphidium gunteri and Elphidium poeyanum. In mesohaline and polyhaline waters of the central part, the organic-carbon-rich silt and clay contain Facies 4, which includes Ammonia beccarii, Pararotalia cananeiaensis, Elphidium excavatum and Elphidium sp. Most of organic-carbon-enriched, silty-clay substrates that are subject to the highest fresh-water discharge and high bottom temperatures support two different assemblages: one of mostly Rotaliina and the

    Highlights: Black-Right-Pointing-Pointer Assessment of medical waste management at health-care center before/after intervention. Black-Right-Pointing-Pointer Qualitative and quantitative results of medical waste management plan are presented. Black-Right-Pointing-Pointer Adjustments to comply with regulation were adopted and reduction of waste was observed. Black-Right-Pointing-Pointer The method applied could be useful for similar establishments. - Abstract: According to the Brazilian law, implementation of a Medical Waste Management Plan (MWMP) in health-care units is mandatory, but as far as we know evaluation of such implementation has not taken place yet. The purpose of the present study is to evaluate the improvements deriving from the implementation of a MWMP in a Primary Health-care Center (PHC) located in the city of Sao Paulo, Brazil. The method proposed for evaluation compares the first situation prevailing at this PHC with the situation 1 year after implementation of the MWMP, thus allowing verification of the evolution of the PHC performance. For prior and post-diagnosis, the method was based on: (1) application of a tool (check list) which considered all legal requirements in force; (2) quantification of solid waste subdivided into three categories: infectious waste and sharp devices, recyclable materials and non-recyclable waste; and (3) identification of non-conformity practices. Lack of knowledge on the pertinent legislation by health workers has contributed to non-conformity instances. The legal requirements in force in Brazil today gave origin to a tool (check list) which was utilized in the management of medical waste at the health-care unit studied. This tool resulted into an adequate and simple instrument, required a low investment, allowed collecting data to feed indicators and also conquered the participation of the unit whole staff. Several non-conformities identified in the first diagnosis could be corrected by the instrument utilized

    Full Text Available With the urbanisation of the population in developing countries and the process of globalisation, Chagas has become an emerging disease in the urban areas of endemic and non-endemic countries. In 2006, it was estimated that the prevalence of Chagas disease among the general Bolivian population was 6.8%. The aim of the present study was to determine the prevalence of Trypanosoma cruzi infection among Bolivian immigrants living in São Paulo, Brazil. This study had a sample of 633 volunteers who were randomly selected from the clientele of primary care units located in the central districts of São Paulo, Brazil. Infection was detected by two different ELISA assays with epimastigote antigens, followed by an immunoblot with trypomastigote antigens as a confirmatory test. The prevalence of the infection was 4.4%. Risk factors independently associated with the infection were: a history of rural jobs in Bolivia, knowledge of the vector involved in transmission, and having relatives with Chagas disease. Brazil has successfully eliminated household vector transmission of T. cruzi, as well as its transmission by blood transfusion. The arrival of infected immigrants represents an additional challenge to primary care clinics to manage chronic Chagas disease, its vertical transmission, and the blood derivatives and organ transplant programs.

    This study evaluated infection by vector-borne agents in 58 crab-eating fox (Cerdocyon thous L.) that were road-killed in an Atlantic rainforest reserve in the state of Espírito Santo, southeastern Brazil. Spleen, lung, or blood samples collected from the foxes were tested in the laboratory by a battery of polymerase chain reaction (PCR) assays targeting bacteria of the genera Rickettsia, Borrelia, Coxiella, Anaplasma, and Ehrlichia; and protozoa of the genera Babesia, Hepatozoon, and Leishmania. Of the targeted organisms, evidence of infection in the foxes was detected for Ehrlichia and Hepatozoon organisms only. Overall, six (10.3%) foxes were infected by an ehrlichial agent closely related to an ehrlichial agent recently detected in free-ranging Jaguars [(Panthera onca (L.)] in central-western Brazil, and to Ehrlichia ruminantium. For Hepatozoon, 28 (48.3%) foxes were infected by an agent closely related to Hepatozoon sp. Curupira 2 and H. americanum; and one (1.7%) fox was infected by an organism closely related to reptile-associated Hepatozoon agents. Finally, 11 (19.0%) foxes were found infested by Amblyomma cajennense (F.) nymphs, which were all PCR negative for the range of vector-borne agents cited above. Because the haplotypes found in free-ranging foxes are genetically closely related to pathogens of great veterinary importance, namely E. ruminantium and H. americanum, it is highly desirable to know if these novel organisms have any important role as agents of diseases in domestic animals and wildlife in Brazil.

The main concern yields the quantifying long-term lithospheric evolution of the continental margin between São Paulo and Laguna in southeastern Brazil since the Neoproterozoic. We put special emphasis on the reactivation of old fracture zones running into the continent and their constrains on the landscape evolution. In this contribution, we represent already consisting thermochronological data attained by fission-track and (U-Th-Sm)/He analysis on apatites and zircons. The zircon fission-track ages range between 108.4 (15.0) and 539.9 (68.4) Ma, the zircon (U-Th-Sm)/He ages between 72.9 (5.8) and 427.6 (1.8) Ma whereas the apatite fission-track ages range between 40.0 (5.3) and 134.7 (8.0) Ma, and the apatite (U-Th-Sm)/He ages between 32.1 (1.52) and 92.0 (1.86) Ma. These thermochronological ages from metamorphic, sedimentary and intrusive rocks show six distinct blocks (Laguna, Florianópolis, Curitiba, Ilha Comprida, Peruibe and Santos) with different evolution cut by old fracture zones. Furthermore, models of time-temperature evolution illustrate the differences in Pre- to post-rift exhumation histories of these blocks. The presented data will provide an insight into the complex exhumation history of the continental margin based on the existing literature data on the evolution of the Paraná basin in Brazil and the latest

    Full Text Available OBJECTIVE: To evaluate the most productive types of properties and containers for Aedes aegypti and the spatial distribution of entomological indices. METHODS: Between December 2006 and February 2007, the vector's immature forms were collected to obtain entomological indices in 9,875 properties in the Jaguare neighborhood of Sao Jose do Rio Preto, SP, Southeastern Brazil. In March and April 2007, a questionnaire about the conditions and characteristics of properties was administered. Logistic regression was used to identify variables associated with the presence of pupae at the properties. Indices calculated per block were combined with a geo-referenced map, and thematic maps of these indices were obtained using statistical interpolation. RESULTS: The properties inspected had the following Ae. aegypti indices: Breteau Index = 18.9, 3.7 larvae and 0.42 pupae per property, 5.2 containers harboring Ae. aegypti per hectare, 100.0 larvae and 11.6 pupae per hectare, and 1.3 larvae and 0.15 pupae per inhabitant. The presence of yards, gardens and animals was associated with the presence of pupae. CONCLUSIONS: Specific types of properties and containers that simultaneously had low frequencies among those positive for the vector and high participation in the productivity of larvae and pupae were not identified. The use of indices including larval and pupal counts does not provide further information beyond that obtained from the traditional Stegomyia indices in locations with characteristics similar to those of São José do Rio Preto. The indices calculated per area were found to be more accurate for the spatial assessment of infestation. The Ae. aegypti infestation levels exhibited extensive spatial variation, indicating that the assessment of infestation in micro areas is needed.

    Full Text Available Due to rapid and continuous deforestation, recent bird surveys in the Atlantic Forest are following rapid assessment programs to accumulate significant amounts of data during short periods of time. During this study, two surveying methods were used to evaluate which technique rapidly accumulated most species (> 90% of the estimated empirical value at lowland Atlantic Forests in the state of São Paulo, southeastern Brazil. Birds were counted during the 2008-2010 breeding seasons using 10-minute point counts and 10-species lists. Overall, point counting detected as many species as lists (79 vs. 83, respectively, and 88 points (14.7 h detected 90% of the estimated species richness. Forty-one lists were insufficient to detect 90% of all species. However, lists accumulated species faster in a shorter time period, probably due to the nature of the point count method in which species detected while moving between points are not considered. Rapid assessment programs in these forests will rapidly detect more species using 10-species lists. Both methods shared 63% of all forest species, but this may be due to spatial and temporal mismatch between samplings of each method.

    Sampling allows assessing the impact of human activities on mammal communities. It is also possible to assess the accuracy of different sampling methods, especially when the sampling effort is similar. The present study aimed at comparing two mammalian surveys carried out over a three-year interval, in terms of sampling effort, capture success, abundance of domestic dogs, impact of human activities, and relative biomass using camera traps, in the Serra do Japi Biological Reserve and surroundings, located in Jundiaí, state of São Paulo, southeastern Brazil. The total richness recorded was 13 species, one domestic and 12 wild mammals. Sampling effort in both surveys was similar, but capture success and number of captures differed. The abundance of wild mammals and dogs did also differ between surveys. There was a highly significant correlation between abundance of wild mammals and capture effort for the survey performed in 2006/2007, but not for the survey performed in 2009/2010. The difference between samples may be related to human disturbance, since the number of domestic mammals photographed was higher in the second survey, three years after the first survey. Despite being a reserve, the area is still under pressure from urbanization, biological invasion, environmental degradation, and hunting, which may reduce the abundance of wild mammals.

    Full Text Available Abstract The evaluation of ecosystem services is a tool to raise awareness about benefits of ecosystem functions for human well-being. In Brazil, few studies and reports assess ecosystem services in a watershed context. The aim of this paper is to fill this gap by assessing ecosystem services of Jacaré-Guaçu and Jacaré-Pepira Watersheds (São Paulo State, Brazil in a temporal scale of 10 years. Land cover and uses’ capacity to provide ecosystem services and drivers were assessed as a result of mapping these areas. Economic values were estimated based on literature information. Results showed that cultivated and managed terrestrial areas stands out over other areas and then, regulation and maintenance services are reduced in these areas. Wetlands and natural vegetation, with smaller areas, are important for the supply of regulation and maintenance services of both watersheds and economic values indicate the magnitude of degradation or maintenance/restoration.

    Full Text Available A serosurvey was conducted in wild animals captured close to two areas where hantavirus cardiopulmonary syndrome (HCPS occurred in São Paulo State, Brazil. Serum samples from a total of 43 mammals were tested for antibodies reactive with Sin Nombre (SN hantavirus using a strip immunoblot assay. RNAs from the blood clots of the positive samples were submitted to reverse transcriptase-polymerase chain reaction (RT-PCR. Two rodents of the genus Oligoryzomys were positive for hantavirus antibodies. These animals were captured in the Iguape region and represented 16.7% (2/12 of the sera from rodents and 100.0% (2/2 of the Oligoryzomys captured in that area. RT-PCR failed to amplify any viral cDNA. These results are in agreement with other data that suggest that members of this genus are important reservoirs of hantaviruses in Brazil.

    The occurence of earthquakes in Brazil, mainly in the South-eastern region, and its relationship with the geologic features has been discussed by many Authors since the beginning of this Century. It is difficult to define intraplate seismicity and to understand the actual epirogenic displacent, but the definition of the regional stability is important for enginnering purposes and have been considered through seismologic, morphotectonic and geologic criteria.

    Megacities, large urban conglomerates with a population of 10 million or more inhabitants, are increasingly receiving attention as strong pollution hotspots with significant global impact. The emissions from such large centers in both the developed and developing parts of the world are strongly impacted by the transportation sector. The São Paulo Metropolitan Area (SPMA), located in the Southeast of Brazil, is a megacity with a population of 18 million people and 7 million vehicles, many of which fuelled by a considerably amount of anhydrous ethanol. Such fleet is considered a unique case of large scale biofuel usage worldwide. Despite the large impact on human health and atmospheric chemistry/dynamics, many uncertainties are found in terms of gas and particulate matter emissions from vehicles and their atmospheric reactivity, e.g. secondary organic aerosol formation. In order to better understand aerosol life cycle on such environment, a suite of instruments for gas and particulate matter characterization has been deployed in two sampling sites within the SPMA, including an Aerosol Chemical Speciation Monitor (ACSM). The instrumentation was deployed at the rooftop of a 45m high building in the University of São Paulo during winter/spring 2012. The site is located roughly 6km downwind of the city center with little influence from local sources. The second site is located in a downtown area, sampling at the top floor of the Public Health Faculty, approximately 10m above ground. The instrumentation was deployed at the Downtown site during summer/fall 2013. The average non-refractory submicron aerosol concentration at the University site was 6.7 μg m-3, being organics the most abundant specie (70%), followed by NO3 (12%), NH4 (8%), SO4 (8%) and Chl (2%). At the Downtown site, average aerosol concentration was 15.1 μg m-3, with Organics composing 65% of the mass, followed by NH4 (12%), NO3 (11%), SO4 (11%) and Chl (1%).

    While hydraulic stimulus on seismic activity is most commonly associated with hydraulic fracturing processes, we find in SE Brazil a rare case of seismicity influenced by hydraulic stimulation linked to seasonal rain and water wells in a farming area. These are thought to be the main factors influencing the seasonal seismicity activity in Jurupema, a farming town located in the interior of the state of Sao Paulo, southern Brazil. With temporary seismic station deployments during 2016 and 2017, we analyze the seismicity in this area, its temporal and spatial distribution, and its association with the drilling of ground water wells in this particular area. In a region where water wells are often drilled to provide irrigation for farming, these are often perforated down to about 100 m depth, penetrating below the uppermost sandstone rock layer ( 50 m) into a fractured basaltic rock layer, reaching the confined aquifer within it. While the wells are constantly pumped during the dry season, during the course of the rainy season (when these are not being used), a possible infiltration into the confined basaltic aquifer, from both the rainwater and the upper sandstone aquifer, adds changes to the pore pressure of the fractured rock, and modifies the tectonic pre-stress conditions, to facilitate stress release mechanisms in pre-existing faults and cracks. With our temporary seismic station deployments, we not only examine the seismicity in this region during both 2016 and 2017, but we additionally compare its characteristics to the nearby Bebedouro case in an apparent induced seismic case of analogous source, and seismic activity with magnitudes up to 2.9 occurring between 2005 and 2010.

    Full Text Available Objective: The treatment of neonatal hyperbilirubinemia remains aproblem because it can lead to sequelae in both children and adults. Theobjective of this study was to evaluate how neonatal jaundice is treatedin maternity hospitals in the city of São Paulo. Methods: Prospective andtransversal study on maternity hospitals in the city of São Paulo, Brazil. Aquestionnaire was applied to doctors working at neonatal wards withinmaternity hospitals in the city of São Paulo, divided into public (n = 6 andprivate maternity clinics (n = 18. The results obtained from the differentitems of the questionnaire were then compared. Statistical analysis wasperformed using the Student’s t test, chi-square test and Mann-Whitneytest when appropriate, and a p value < 0.005 was considered significant.Results: There were no significant differences between the two typesof maternity hospitals in relation to the treatment method for neonataljaundice. However, among private maternities there were some that didnot have written guidelines (5/17 and those that performed exchangetransfusion (3/18. Teaching was significantly more present amongpublic (100% than private maternity hospitals (17.6%. The mean serumbilirubin levels to initiate treatment did not show significant differencesbetween the two types of maternities. Some clinical practices in use bymaternity hospitals are not evidence based. Conclusions: The presentdata were considered preliminary and showed that further research inthe area is required and if our findings are confirmed, indicate the needfor continuous medical education on the part of health professionals incharge of newborns.

    To analyze alcohol, tobacco and other drug use among medical students. Over a five-year period (1996-2001), we evaluated 457 students at the Universidade de São Paulo School of Medicine, located in São Paulo, Brazil. The students participated by filling out an anonymous questionnaire on drug use (lifetime, previous 12 months and previous 30 days). The influence that gender and academic year have on drug use was also analyzed. During the study period, there was an increase in the use of illicit drugs, especially inhalants and amphetamines, among the medical students evaluated. Drug use (except that of marijuana and inhalants) was comparable between the genders, and academic year was an important influencing factor. Increased inhalant use was observed among the medical students, especially among males and students in the early undergraduate years. This is suggestive of a specific behavioral pattern among medical students. Our findings corroborate those of previous studies. Inhalant use is on the rise among medical students at the Universidade de São Paulo School of Medicine. Because of the negative health effects of illicit drug use, further studies are needed in order to deepen the understanding of this phenomenon and to facilitate the development of preventive measures.

    Full Text Available The aim of this study was to evaluate the prevalence of caries-free children using DMFT and significant caries (SiC indexes in different caries prevalence groups in cities of the region of Campinas, São Paulo State, Brazil. The methodology proposed by the World Health Organization (1997 was used for caries diagnosis in 2,378 individuals. According to the DMFT index obtained in each evaluated city, 3 prevalence groups with representative samples were formed, being classified as low, moderate and high. SiC index was used to classify the one third of the population with the highest caries prevalence. In the low prevalence group, 32.4% of the children were caries free (DMFT=0, with mean DMFT of 2.29 and SiC index of 4.93. In the moderate prevalence group, 21.8% of the children were caries free, with mean DMFT of 3.36 and SiC of 6.74. Only 6.9% of the children in the high prevalence group were caries free and the mean DMFT was 5.54 (SiC=9.62. There was a great heterogeneity in dental caries distribution within the studied population, as well as a high caries prevalence considering the 3 classifications. Other indexes besides DMFT could be used to improve oral health assessment during establishment of the treatment plan and intervention.

    This study aimed to report the infection by Sphincterodiplostomum musculosum metacercariae in Steindachnerina insculpta from the Chavantes Reservoir, medium Paranapanema River, municipality of Ipaussu, State of São Paulo, Brazil. Thirty specimens of S. insculpta were collected and 29 were infected with S. musculosum metacercariae (prevalence = 96.67%) in the eyes and visceral cavity. The mean intensity of infection and abundance were 96.6 ± 29.41 (7-846) and 93.3 ± 28.6 (0-846), respectively. Positive correlation was observed between parasite abundance in the eyes and standard length (rs = 0.5, p = 0.005), total weight (rs = 0.649, p = 0.0001), and condition factor (rs = 0.439, p = 0.0154). The high parasitism rates by S. musculosum metacercariae in S. insculpta can be an indicative that this fish species is highly susceptible to infection by this diplostomid, and even reflect the presence of a large abundance of the intermediate host. Moreover, S. musculosum metacercariae are reported for the first time in S. insculpta.

    This paper discusses, within the prevailing Brazilian situation, the possibility of applying "causal tree" (CT) method in investigating occupational accidents by safety personnel in the public health services and workers' unions. The method was developed during the seventies in France, for use by plant safety personnel. The authors used this method in Botucatu, state of São Paulo, Brazil, in order to investigate 40 serious occupational accidents that occurred in industrial plants during the second half of 1993, that had been registered by social security. In these cases, the predominance of situations in which the lack of safety measures were identified by inspection indicates that in most instances, the use of CT is unnecessary. However, the authors discuss its use by safety personnel from the public health services and workers' unions to investigate certain accidents to contribute to the knowledge base and help overcome the cultural based guilt which, in Brazil, has turned the victim into the person responsible for the accident.

    Crop residues returned to the soil are important to preserve fertility and sustainability. This research addressed the long-term decomposition of sugarcane post-harvest residues (trash) under reduced tillage, therefore field renewal was performed with herbicide followed by subsoiling and ratoons were deprived of interrow scarification. The trial was conducted in the northern Sao Paulo State, Brazil during four consecutive crops (2005–2008) where litter bags containing 15 N-labeled trash were disposed in the field attempting to simulate two distinct situations: the previous crop trash (PCT) or residues incorporated in the field after tillage, and post-harvest trash (PHT) or the remains of plant-cane harvest. Decomposition rates regarding dry matter (DM), carbon (C), root growth, plant nutrients (N, P, K, Ca, Mg and S), lignin (LIG) cellulose (CEL) and hemicellulose (HCEL) contents were assessed for PCT (2005 ndash;2008) and for PHT (2006–2008). There were significant reductions on DM and C:N ratio due to C losses and root growth within the litter bags over time. The DM from PCT and PHT decreased 96% and 73% after four and three crops, respectively, and the higher nutrients release were found for K, Ca and N. The LIG, CEL and HCEL concentrations in PCT decreased 60%, 29%, 70% after four crops and 47%, 35%, 70% from PHT after three crops, respectively. Trash decomposition was driven mainly by residues biochemical composition, root growth within the trash blanket and the climatic conditions during the crop cycles. -- Highlights: ► Degradation of sugarcane previous or post-harvest trash (PCT or PHT) was evaluated. ► Dry matter and C decreased due to microbial and root growth within trash blankets. ► C:N ratio of PCT linearly decreased 23% per year during four consecutive crops. ► Lignin, cellulose and hemicellulose concentration averagely declined 54, 41 and 70%. ► PCT and PHT are long-term sources of C, K, Ca and N to the soil-plant system.

    To describe the experience of a registered nurse (RN) training process related to the Family Health Program (FHP) developed in the city of São Paulo, Brazil. The FHP is a national, government strategy to restructure primary care services. It focuses on the family in order to understand its physical and social structure in regards to the health-illness process. In the FHP, the RN is a member of a team with the same number as medical doctors - an unprecedented situation. The FHP requires a discussion of the RNs' practice, by qualifying and empowering them with tools and knowledge. The training process was based on Freire's approach founded on critical pedagogy in order to address the fundamental problem of inequalities in health. The first phase included workshops and the second one included a course. The workshops identified the following problems related to the RN's work: lack of tools to identify the population's needs; overload of work due to the accumulation of management and assistance activities; difficulties regarding teamwork; lack of tools to evaluate the impact of nursing interventions; lack of tools to improve the participation of the community. The course was organized to tackle these problems under five thematic headings. The RN's training process allowed the group to reflect deeply on its work. This experience led to the need for the construction of tools to intervene in the reality, mainly against social exclusion, rescuing and adapting of the knowledge accumulated in the healthcare practice, identifying settings which demand institutional solutions and engaging the RN in research groups in order to develop projects according to the complexity of the primary care services. The application of the concept of equity in the health sector represented a reaction against the processes of social exclusion, starting from performance at a local level to become a reality in the accomplishments achieved by the Brazilian National Health System.

    Tillandsia usneoides L. is an epiphytic bromeliad plant able to absorb water and nutrients directly from the air. For this reason this species was selected to carry out a monitoring study of air pollution in the metropolitan region of Sao Paulo, Brazil. Five consecutive transplantation experiments (8 weeks each) were performed in 10 sites of the city, submitted to different sources of air pollution (industrial, vehicular), using plants collected from an unpolluted area. After exposure, trace metals were analyzed in the plant by instrumental neutron activation analysis. Traffic-related elements such as Zn and Ba presented high concentrations in exposure sites near to heavy traffic avenues (cars, buses and trucks) and may be associated to vehicular sources. For Zn and Co the highest contents were related to industrial zones and can be associated to the presence of anthropogenic emission sources. The rare earth elements, Fe and Rb, probably have soil particles as main source. - This paper is the first work on the use of biomonitors to assess metal pollution in Sao Paulo, Brazil, the biggest city in Latin America

    Evaluation of short-term mortality displacement is essential to accurately estimate the impact of short-term air pollution exposure on public health. We quantified mortality displacement by estimating single-day lag effects and cumulative effects of air pollutants on mortality using distributed lag models. We performed a daily time series of nonaccidental and cause-specific mortality among elderly residents of São Paulo, Brazil, between 2000 and 2011. Effects of particulate matter smaller than 10 μm (PM 10 ), nitrogen dioxide (NO 2 ) and carbon monoxide (CO) were estimated in Poisson generalized additive models. Single-day lag effects of air pollutant exposure were estimated for 0-, 1- and 2-day lags. Distributed lag models with lags of 0-10, 0-20 and 0-30 days were used to assess mortality displacement and potential cumulative exposure effects. PM 10 , NO 2 and CO were significantly associated with nonaccidental and cause-specific deaths in both single-day lag and cumulative lag models. Cumulative effect estimates for 0-10 days were larger than estimates for single-day lags. Cumulative effect estimates for 0-30 days were essentially zero for nonaccidental and circulatory deaths but remained elevated for respiratory and cancer deaths. We found evidence of mortality displacement within 30 days for nonaccidental and circulatory deaths in elderly residents of São Paulo. We did not find evidence of mortality displacement within 30 days for respiratory or cancer deaths. Citation: Costa AF, Hoek G, Brunekreef B, Ponce de Leon AC. 2017.

    This study described the sociodemographic profile and professional qualifications of pediatric intensive care physicians in the State of Rio de Janeiro (RJ), southeastern Brazil. This investigation was an observational, cross-sectional and descriptive study that was conducted in neonatal, pediatric and mixed intensive care units in the State of Rio de Janeiro. Physicians working in the participating intensive care units voluntarily completed a semistructured and anonymous questionnaire. Questionnaires that were not returned within 30 days were considered lost, and questionnaires with less than 75% questions completed were excluded. The differences in neonatal and pediatric intensive care physicians' medical training were compared using the Chi-squared test with a 5% significance level. A total of 410 physicians were included in this study: 84% female, 48% between 30 and 39 years old and 45% with monthly incomes between US $1,700 to 2,700. Forty percent of these physicians worked exclusively in this specialty, and 72% worked in more than one intensive care unit. Only 50% of the participants had received specific training (either medical residency or specialization) in neonatology, and only 33% were board-certified specialists in this area. Only 27% of the physicians had received specific training in pediatric intensive care medicine, and only 17% were board-certified specialists (p professional activity; 49% were dissatisfied due to working conditions, 23% due to low incomes and 18% due to training-related issues. These results suggested that the medical qualifications of neonatal and pediatric intensive care physicians in the State of Rio de Janeiro, Brazil are inadequate, especially in pediatric intensive care medicine. A high level of dissatisfaction was reported, which may jeopardize the quality of medical assistance that is provided by these professionals.

    To analyze the profile of claimants and medicines demanded in lawsuits. Descriptive study that examined 827 lawsuits with 1,777 demands of access to medicines in the period between July 2005 and June 2006 in the state of Minas Gerais, Southeastern Brazil. There were examined the type of health care provided to claimants and their attorneyship. The medicines were described based on the following: drug registration at the National Health Surveillance Agency (Anvisa); wheter they were essential medicines; supply in the Brazilian Health System programs; and evidence of drug efficacy. More than 70% of the claimants were provided care in the private health system and 60.3% hired private lawyers. The most common diagnosis of claimants was rheumatoid arthritis (23.1%) and the immunosuppressant agents were the most frequent demand medicines (mainly adalimumab and etanercept). Approximately 5% of the medicines demanded were not registered at Anvisa, 19.6% were included in the Brazilian List of Essential Medicine, 24.3% were included in the High-Cost Drug Program and 53.9% showed consistent evidence of efficacy. Among the medicines that were not available in Brazilian Health System, 79.0% had therapeutic alternatives in drug programs. The phenomenon of judicialization of health in Brazil can point out failures in the public health system as some medicines demanded are included in its lists. However, it is a barrier for rational drug use and application of the National Drug Policy guidelines, especially when there are demanded medicines with no evidence of efficacy and that are not included in Brazilian Health System standards.

    The mangrove crab Ucides cordatus is one of the most exploited crustaceans in Brazil. The present study investigated the breeding season of this species and the period of the "andada" phenomenon, when the crabs are active outside their burrows and perform agonistic behaviors. Furthermore related them to environmental factors, in a mangrove on the coast of Brazil, with inferences about management of this crab. The crabs reproduced from October through February. The "andada" occurred from November through February, with typical characteristics in the first two months, during the full and new moon periods, and was influenced positively by the air and soil temperature, luminosity, and tidal amplitude, and negatively by salinity. Based on the results of the present study, the period when the "andada" occurs in other parts of Brazil could be defined, which will aid in managing this fishery. For Iguape, state of São Paulo, Brazil, we suggest a legal off-season for both sexes in December or during the full and new moon, including January.

    Full Text Available Bolivian immigrants in Brazil experience serious social problems: precarious work conditions, lack of documents and insufficient access to health services. The study aimed to investigate inequalities in living conditions and access to health services among Bolivian immigrants living in the central area of São Paulo, Brazil, using a cross-sectional design and semi-structured interviews with 183 adults. According to the data, the immigrants tend to remain in Brazil, thus resulting in an aging process in the group. Per capita income increases the longer the immigrants stay in the country. The majority have secondary schooling. Work status does not vary according to time since arrival in Brazil. The immigrants work and live in garment sweatshops and speak their original languages. Social networks are based on ties with family and friends. Access to health services shows increasing inclusion in primary care. The authors conclude that the immigrants' social exclusion is decreasing due to greater access to documentation, work (although precarious, and the supply of health services from the public primary care system.

    We studied infestation rates and parasite-host associations between streblid flies and phyllostomid bats in an Atlantic Forest area of Rio de Janeiro state, southeastern Brazil. We captured 301 individuals from seven Phyllostomidae bat species. Out of that total, 69 bats had been parasitised by nine Streblidae species; the most frequent species were Trichobius joblingi and Trichobius tiptoni. The species Paraeuctenodes longipes, associated with Anoura geoffroyi, was the most frequent species. The highest mean intensity was observed for Paraeuctenodes longipes, associated with A. geoffroyi, and Paratrichobius longicrus associated with Artibeus lituratus, both ectoparasite species with a mean intensity of five individuals per bat. Trichobius joblingi exhibited the highest mean abundance, which was over three on its host species. Streblid richness in the study area was similar to the richness found in other studies carried out in the Atlantic Forest. We observed that streblid richness in this biome depends more on inherent characteristics of each physiognomy and on the host-species than on the sampling effort.

    To analyze sociocultural differences and perceptions of gynecological consultations for high school girls. A transversal study with 418 high school girls from three schools of different profiles in the city of Rio de Janeiro, Southeastern Brazil in 2010. A structured questionnaire encompassing socio-demographic characteristics, sexual behavior and evaluation of gynecological consultations was completed. Yates' Chi-square test and the Student's t-test were utilized adopting a value of p students of private and federal public schools presented similar profiles but both were different from the state school girls. The latter had lower socioeconomic status, and their parents had lower levels of education, the predominance of afro-descendants was observed, as were a larger number of sexual partners, pregnancy and cases of sexual violence. The average age of menarche and sexarche among the students were similar, but the first gynecological consultation was significantly later among the state school students. The majority showed some knowledge of contraception and STDs, although only a minority received guidance from the consultations. Students expressed the desire that the professionals dedicate more time, patience and availability to them during consultations. The provision of gynecological services for teenagers is not satisfactory, according to the teenagers' evaluations. Users of the private health system have gynecological consultations earlier than those who only have access to the public system. It is necessary to create mechanisms that facilitate access and adhesion to a routine of gynecological prevention for this age group.

    Full Text Available Lontra longicaudis (Olfers, 1818 (Carnivora, Mustelidae is a semi-aquatic animal spread through the Central and South America, except in Chile. The implantation of a hydroelectric power plant along a river alters the dynamics of the watercourse, transforming a lotic environment into a lentic or semilotic one, what can damage the otter's feeding. From April 2008 to March 2009 we analysed the otter's food habits in lotic (streamlet and semilotic (hydroelectric reservoir environments of Paranapanema Valley, in southeastern Brazil. Aiming to compare the otter's diet of these two environments, we analyzed statistically the frequency of occurrence of main items in the scats. Fishes represent the base of the diet both in the reservoir and in the streamlet and, despite of the total otter's diet showing up similarities in the two environments, the results evidenced modifications on the fish species consumed between them. In the reservoir the otters ate more exotic fish Oreochromis niloticus (Linnaeus, 1758 probably because it is an easy capture prey in this place. The fact that the otters get established and feed in the reservoir doesn't mean that this structure is benefic to the species because the food supplied for it consists mainly of exotic fish species.

    Full Text Available The Lajeado Group in the Ribeira Belt, southeastern Brazil, corresponds to an open-sea carbonate platform, comprised of seven overlapping siliciclastic and carbonatic formations, intruded in its upper portion by the Apiaí Gabbro. These rocks have a Neoproterozoic tectonometamorphic overprint related to arc magmatism and the Brasiliano collisional orogeny. Geochronological constraints are given by new U-Pb SHRIMP and LA-ICP-MS data for Lajeado Group detrital zircons and for magmatic zircons from the Apiaí Gabbro. The youngest detrital zircons in the Lajeado Group are 1400–1200 Ma, and constrain its maximum age of deposition to be <1200 Ma, whereas the 877 ± 8 Ma age for magmatic zircons in the Apiaí Gabbro give the minimum age. Detritus source areas are mainly Paleoproterozoic (2200–1800 Ma with some Archean and Mesoproterozoic contribution (1500–1200 Ma, with distal or tectonic stable cratonic character. The Lajeado Group should be a Stenian–Tonian carbonate platform passive margin of a continent at this time, namely the Columbia/Nuna or the Rodinia. The Apiaí Gabbro displays similar age to other intrusive basic rocks in the Lajeado and Itaiacoca groups and represents tholeiitic MORB-like magmatism that we relate to the initial break-up of a Mesoproterozoic continent and the formation of the Brasiliano oceans.

    Full Text Available Epidemiological and health aspects of sheep husbandry were assessed on 213 sheep flocks in 142 municipalities from the state of Minas Gerais, southeastern Brazil. An updated questionnaire was filled out for each flock, requesting data on the farm, the flock and the farmer by the veterinarians of the State Government Agency for Animal Health (Instituto Mineiro de Agropecuária. Thirteen important variables were selected and scored to determine the technological level of the 117 farms; 0.9% of them was classified as high technological level, 45.3% as medium technological level and 53.0% as low technological level. Lamb production was the main objective of the farms and the main features were low-frequencies of individual identification of animals (16.9%, technical assistance (31.9%, use of quarantine for newly acquired animals (0.9% the separation of animals by age group (3.7% and requeste the sanitary certificate at purchasing of animals (11.7%. The main health problems reported were abortion (23.9%, keratoconjunctivitis (17.9%, contagious ecthyma (13.6%, pneumonia (10.3%, diarrhea (9.3% and caseous lymphadenitis (6.1%. Information of the epidemiological situation and the mainly health measures used in the sheep farms are important to improve the productivity and quality of the lamb.

    Full Text Available ABSTRACT Existing knowledge of the breeding success and life history characteristics of most Neotropical bird species is scarce. Here, we help fill this gap by analyzing aspects of the breeding biology of the Tropical Kingbird Tyrannus melancholicus (Vieillot, 1819, which is a good model for this kind of study as it is a common species occurring in various environments, including urban areas, but little is known about its life history. We provide results concerning the breeding period, clutch size, incubation and nestling periods, description of nests, eggs and nestlings, and the plants used for nest sites by this species. Fifty-four nests were monitored over two seasons (2012-2014 in a protected area in southeastern Brazil. Nesting began at the end of the dry season and the beginning of the rainy season. The frequency of active nests varied according to variations in rainfall for each breeding season analyzed. The means and standard deviations of the incubation period (14.2 ± 1.9 days, nestling period (15.1 ± 0.8 days and clutch size (2.5 ± 0.7 eggs were similar to values reported for other Neotropical passerines. Twenty-one plant species used as nest trees and for the construction of the nests were identified. The results show that T. melancholicus is not highly selective when choosing plant species used for nest construction.

    Agrosilvopastoral and silvopastoral systems can increase carbon sequestration, offset greenhouse gas (GHG) emissions and reduce the carbon footprint generated by animal production. The objective of this study was to estimate GHG emissions, the tree and grass aboveground biomass production and carbon storage in different agrosilvopastoral and silvopastoral systems in southeastern Brazil. The number of trees required to offset these emissions were also estimated. The GHG emissions were calculated based on pre-farm (e.g. agrochemical production, storage, and transportation), and on-farm activities (e.g. fertilization and machinery operation). Aboveground tree grass biomass and carbon storage in all systems was estimated with allometric equations. GHG emissions from the agroforestry systems ranged from 2.81 to 7.98 t CO 2 e ha -1 . Carbon storage in the aboveground trees and grass biomass were 54.6, 11.4, 25.7 and 5.9 t C ha -1 , and 3.3, 3.6, 3.8 and 3.3 t C ha -1 for systems 1, 2, 3 and 4, respectively. The number of trees necessary to offset the emissions ranged from 17 to 44 trees ha -1 , which was lower than the total planted in the systems. Agroforestry systems sequester CO 2 from the atmosphere and can help the GHG emission-reduction policy of the Brazilian government.

    Full Text Available Assessing the composition of an area's bat fauna is typically accomplished by using captures or by monitoring echolocation calls with bat detectors. The two methods may not provide the same data regarding species composition. Mist nets and harp traps may be biased towards sampling low flying species, and bat detectors biased towards detecting high intensity echolocators. A comparison of the bat fauna of Fazenda Intervales, southeastern Brazil, as revealed by mist nets and harp trap captures, checking roosts and by monitoring echolocation calls of flying bats illustrates this point. A total of 17 species of bats was sampled. Fourteen bat species were captured and the echolocation calls of 12 species were recorded, three of them not revealed by mist nets or harp traps. The different sampling methods provided different pictures of the bat fauna. Phyllostomid bats dominated the catches in mist nets, but in the field their echolocation calls were never detected. No single sampling approach provided a complete assessment of the bat fauna in the study area. In general, bats producing low intensity echolocation calls, such as phyllostomids, are more easily assessed by netting, and bats producing high intensity echolocation calls are better surveyed by bat detectors. The results demonstrate that a combined and varied approach to sampling is required for a complete assessment of the bat fauna of an area.

  1. Feeding ecology of the beach silverside Atherinella blackburni (Atherinopsidae in a tropical sandy beach, Southeastern Brazil

    Júlio Guazzelli Gonzalez

    Full Text Available Abstract The feeding ecology of the beach silverside (Atherinella blackburni in the surf zone of a tropical sand beach, located in the southeastern Brazil, was accessed through the gut content analysis of 198 fish. Factors such as fish's size, season and day period were analysed to understand how these variables affect the diet composition of the species. Results show that A. blackburni is a coastal neritic fish with a broad feeding niche. Most recurrent prey were zooplanktonic crustaceans, insects and benthic molluscs, in which Copepoda crustaceans were the dominant dietary item in occurrence and abundance. A. blackburni appears to have a slight ontogenetic shift in its diet, changing from benthic molluscs to crustaceans and insects along its life cycle. The diel activity also reveals to be an important factor to the A. blackburni feeding ecology. The predominant occurrence of small fish during the morning, along with the main preys for this size class, suggests that small individuals use shallower waters as feeding grounds during the morning and, during the night, they move to deeper waters for protection against predators.

Light and scanning electron microscopy were used and the species were grouped into three pollen types, organized according to aperture characteristics: Type I - pantoporate pollen grains observed in P. petropolitana, Type II - 2-porate pollen grains, observed in the genera Ananas, Aechmea and Quesnelia, and Type III - 1-colpate pollen grains, observed in the genera Billbergia, Pitcairnia, Tillandsia and Vriesea. Pollen data led to the construction of an identification key. The results showed that the species analyzed can be distinguished using mainly aperture features and exine ornamentation, and that these characteristics may assist in taxonomic studies of the family.

    Full Text Available The aims of this study were to evaluate the seasonal variation and frequency distribution of Rhipicephalus (Boophilus microplus, Haematobia irritans, and Dermatobia hominis on crossbred heifers under field conditions in the northeast of Minas Gerais state, southeastern Brazil. From November 2007 to September 2009 (23 months, 40 heifers aged 16.6±2.4 months were divided into groups A (1/4 Holstein × 3/4 Gir and B (1/2 Holstein × 1/2 Gir and had the monthly infestation estimated along with the climatic conditions. The mean maximum and minimum temperatures were 28.5 and 19°C, respectively. The ectoparasites were present on animals in all months of the year. The levels of ticks on the animals were low (3.0±0.2 ticks/animal, with the highest density in midwinter. The temperature was the climatic factor that most influenced the tick levels. The population of H. irritans (13.9±0.3 flies/animal and D. hominis (1.5±0.2 larvae/animal on heifers was more influenced by rainfall and exhibited two population peaks during the year. 1/2 Holstein heifers harbored significantly more H. irritans and D. hominis than 1/4 Holstein heifers. The results are discussed considering the most appropriate periods to apply ectoparasiticides and the genetic make-up of the animals.

    Full Text Available We determined in this study the habitat preferences of seven native fish species in a regulated river in Southeastern Brazil. We tested the hypothesis that fishes differ in habitat preference and that they use stretches of the river differing in hydraulic characteristics and substrate type. We surveyed fishes in four 1-km long river stretches encompassing different habitat traits, where we also measured water depth, velocity, and substrate type. We investigated preference patterns of four Siluriformes (Loricariichthys castaneus, Hoplosternum littorale, Pimelodus maculatus, and Trachelyopterus striatulus and three Characiformes (Astyanax aff. bimaculatus, Oligosarcus hepsetus, and Hoplias malabaricus, representing approximately 70% of the total number of fishes and 64% of the total biomass. We classified fishes into four habitat guilds: (1 a slow-flowing water guild that occupied mud-sand substrate, composed of two Siluriformes in either shallow ( 8 m, L. castaneus waters; (2 a run-dwelling guild that occurs in deep backwaters with clay-mud substrate, composed of the Characiformes A. aff. bimaculatus and O. hepsetus; (3 a run-dwelling guild that occurs in sandy and shallow substrate, composed of T. striatulus; and (4 a fast-flowing guild that occurs primarily along shorelines with shallow mud bottoms, composed of H. malabaricus and P. maculatus. Our hypothesis was confirmed, as different habitat preferences by fishes appear to occur in this regulated river.

    Full Text Available Southeastern Brazil is the most populated and economically developed region of this country. Its climate consists of two distinct seasons: the dry season, extending from April to September, the precipitation is significantly reduced in comparison to that of the wet season, which extends from October to March. However, during nine days of the 2016 dry season, successive convective systems were associated with atypical precipitation events, tornadoes and at least one microburst over the southern part of this region. These events led to flooding, damages to buildings, shortages of electricity and water in several places, many injuries, and two documented deaths. The present study investigates the synoptic and dynamical features related to these anomalous events. The convective systems were embedded in an unstable environment with intense low-level jet flow and strong wind shear and were supported by a sequence of extratropical cyclones occurring over the Southwest Atlantic Ocean. These features were intensified by the Madden–Julian oscillation (MJO in its phase 8 and by intense negative values of the Pacific South America (PSA 2 mode.

    Full Text Available Conservation of mayflies (Insecta, Ephemeroptera in Espírito Santo, southeastern Brazil. Ephemeroptera exhibits great diversity among bodies of freshwater in the Atlantic Forest, a biome that is suffering from massive human impact. Within this context, the creation of conservation units using biological information is more recommended than economic, cultural, or political criteria. The distribution pattern of 76 Ephemeroptera species was analyzed using the biogeographical methods Parsimony Analysis of Endemicity and Network Analysis Method in order to infer relevant areas for conservation of the mayfly community in Espírito Santo. The results obtained from both analyses were largely congruent, and pointed out four relevant areas for conservation: two in the south of the state, where conservation units or priority areas for conservation are well established; and two in the north, a region in the state where little conservation efforts have been historically done. Therefore, based on our analyses on mayflies, we recommend the expansion of the existing APCs or the creation of new APCs on the north of Espírito Santo.

    In Southeastern Brazil tilapia culture is conducted in extensive and semi-intensive flow-through earthen ponds, being water availability and flow management different in the rainy and dry seasons. In this region lettuce wastes are a potential cheap input for tilapia culture. This study examined the ecological processes developing during the rainy and dry seasons in three extensive flow-through earthen tilapia ponds fertilized with lettuce wastes. Water quality, plankton and sediment parameters were sampled monthly during a year. Factor analysis was used to identify the ecological processes occurring within the ponds and to construct a conceptual graphic model of the pond ecosystem functioning during the rainy and dry seasons. Processes related to nitrogen cycling presented differences between both seasons while processes related to phosphorus cycling did not. Ecological differences among ponds were due to effects of wind protection by surrounding vegetation, organic loading entering, tilapia density and its grazing pressure on zooplankton. Differences in tilapia growth among ponds were related to stocking density and ecological process affecting tilapia food availability and intraspecific competition. Lettuce wastes addition into the ponds did not produce negative effects, thus this practice may be considered a disposal option and a low-cost input source for tilapia, at least at the amounts applied in this study.

    Aquifers can be key players in regional water resources. Precipitation infiltration is the most relevant process in recharging the aquifers. In that regard, understanding precipitation changes and impacts on the hydrological cycle helps in the assessment of groundwater availability from the aquifers. Regional modeling systems can provide precipitation, near-surface air temperature, together with soil moisture at different ground levels from coupled land-surface schemes. More accurate those variables are better the evaluation of the precipitation impact on the groundwater. Downscaling of global reanalysis very often employs regional modeling systems, in order to give more detailed information for impact assessment studies at regional scales. In particular, the regional modeling system, Satellite-enhanced Regional Downscaling for Applied Studies (SRDAS), might improve the accuracy of hydrometeorological variables in regions with spatial and temporal scarcity of in-situ observations. SRDAS combines assimilation of precipitation estimates from gauge-corrected satellite-based products with spectral nudging technique. The SRDAS hourly outputs provide monthly means of atmospheric and land-surface variables, including precipitation, used in the calculations of the hydrological budget terms. Results show the impact of changes in precipitation on groundwater in the aquifer located near the southeastern coastline of Brazil, through the assessment of the water-cycle terms, using a hydrological model during dry and rainy periods found in the 15-year numerical integration of SRDAS.

    Public policy of payment for environmental services (PES) was established in 2007 to face the challenge of recuperatingwater resources at one of the headwater areas of the Jaguari River Basin, which supplies an important reservoir for the metropolitan region of São Paulo, Brazil. Such effort consists of reforestation of riparian zones and spring lands at the hills of selected catchments, including the Ribeirão das Posses (RP) catchment. Since 2012 the University of São Paulo has developed research at RP to monitor the benefits of these practices on stream water quality, and identified a few parameters as good indicators to follow up the results of this PES program. The present study has the objective to show results of the monthly monitoring in2015,including 13 sampling stations at RP catchment distributed as follows: one in a spring forested area, three in spring areas of different ages of reforestation (3, 5 and 8 years), and nine at reaches of RP streamlocated in a way to contemplate the effects of the first order streams that comes from the studied spring areas entering RP. We established two additional stations at the Jaguari River, upstream and downstream of RP outlet. In situ measurements include temperature, pH, electric conductivity (EC) and dissolved oxygen (DO), and collect water samples to bring to the laboratory for analyses of dissolved organic and inorganic carbon (DOC and DIC), total nitrogen (TN) and alkalinity. Also, sediments (fine fraction: >0.45 μm; and coarse fraction: >63 μm) are collected for isotopic carbon analyses. Preliminary results show pH values ranging from 5.5 to 7.8, while DO ranges from 5.8 to 8.9 mg L-1. As for EC, the mean at the spring forested station was 34.6 μS cm-1, while at spring areas of 3, 6 and 8 years of reforestation they were 53.3, 73.8 and 34.8 μS cm-1, respectively. We expected that by the end of this annual monitoring the benefits of reforestation will be affirmed.

    The exposure of populations in risk areas is a matter of global concern, because it is a determining factor for the natural disasters occurrences. Furthermore, it has also been observed an intensification of extreme hydrometeorological events that has triggered disasters in various parts of the globe, further increasing the need for monitoring and alerting for natural disasters, aiming the safeguarding of life and minimize economic losses. Accordingly, different methodologies for risk assessment have been proposed, focusing on the specific natural hazards. Particularly for Brazil, which has economic axis of development in the regions near the coast, it is common to observe the process of urbanization advancing on steep slopes of the mountain regions. This characteristic causes the population exposure to the natural hazards related to the mass movements, which the landslides stood out as the cause of many deaths and economic losses every year. Thus, prior to risk analysis (when human occupation intersect with natural hazard), it is essential to analyze the susceptibility, which reflects the physical and environmental conditions that trigger for such phenomena. However, this task becomes a major challenge due to the difficulty of finding databases with good quality. In this context, this paper presents a methodology based only on spatial information in the public domain, integrated into a Geographic Information System free, in order to analyze the landslides susceptibility. In a first effort, we evaluated four counties of Southeastern Brazil - Santos, Cubatão, Caraguatatuba and Ubatuba - located in a region that includes the rugged reliefs of Serra do Mar and the transition to the coastal region, that have historic of disasters related. It is noteworthy that the methodology takes into account many variables that was weighted and crossed by Fuzzy Gamma technique, such as: topography (horizontal and vertical curvature of the slopes), geology, geomorphology, slope

Snowball sampling with multiple focuses was used to recruit Korean immigrants older than 18 years and living in São Paulo. A total of 324 Korean immigrants were selected and their mental status was evaluated using a structured interview, namely the Portuguese or the Korean version of the Composite International Diagnostic Interview 2.1. The diagnoses of mental disorders were made according to the ICD-10. The frequency of any lifetime psychiatric disorder was 41.9%. The frequencies of main disorders were: anxiety disorder, 13% (post-traumatic stress disorder, 9.6%; mood disorder, 8.6%; somatoform disorders, 7.4%; dissociative disorder, 4.9%; psychotic disorder, 4.3%; eating disorder, 0.6%; any substance (tobacco, alcohol, drugs use disorder, 23.1%. The frequency of any psychiatric disorder except alcohol and tobacco use disorders was 26.2%. Korean immigrants have more psychiatric disorders than the Korean population in Korea, particularly post-traumatic stress disorder, and almost the same rate as the Brazilian population. Mental health authorities should promote a healthier integration and the development of culturally sensitive mental health programs for Korean immigrants.Este estudo verificou a freqüência de transtornos psiquiátricos em uma comunidade de imigrantes coreanos na cidade de São Paulo, Brasil.

    is known about such interference in our latitude. OBJECTIVES: To determine whether there are seasonal variations in venous thromboembolism in a hospital-based population in São Paulo, Brazil, which has subtropical climate. METHODS: Medical records of patients admitted to Hospital da Beneficência Portuguesa de São Paulo with the diagnosis of deep venous thrombosis or pulmonary thromboembolism were reviewed from January 1996 to October 2003. Cases were grouped in trimesters (first trimester = January, February and March; second trimester = April, May and June; third trimester = July, August and September; fourth trimester = October, November and December. They were also grouped as to warm and cold months, according to mean temperature (warm months = October through April; cold months = May through September. RESULTS: A total of 955 cases of venous thromboembolism were found during the study period. The ANOVA test was used for statistical analysis, showing no significant difference in the occurrence of venous thromboembolism considering the four trimesters. Separate analysis of deep venous thrombosis and pulmonary embolism incidence showed no differences either. Comparing warm and cold months, there was an increased incidence of deep venous thrombosis during warm months (p < 0.05, Mann-Whitney test. CONCLUSION: Venous thromboembolism is not clearly related to climatic variations. The influence of climate and temperature on blood coagulability is poorly understood and needs to be further studied.

    Brazil has an important role in the biomass burning, with the detection of approximately 100,000 burning spots in a single year (2007). Most of these spots occur in the southern part of the Amazon basin during the dry season (from August to november) and these emissions reach the southeast of the country, a highly populated region and with serious urban air pollution problems. With the growing demand on biofuels, sugarcane is considerably expanding in the state of Sao Paulo, being a strong contributor to the bad air quality in this region. In the state of Sao Paulo, the main land use are pasture and sugarcane crop, that covers around 50% and 10% of the total area, respectively. Despite the aerosol from sugarcane burning having reduced atmospheric residence time, from a few days to some weeks, they might get together with those aerosol which spread over long distances (hundreds to thousands of kilometers). In the period of June through February 2010 a LIDAR observation campaign was carried in the state of Sao Paulo, Brazil, in order to observe and characterize optically the aerosols from two distinct sources, namely, sugar cane biomass burning and industrial emissions. For this purpose 2 LIDAR systems were available, one mobile and the other placed in a laboratory, both working in the visible (532 nm) and additionally the mobile system had a Raman channel available (607 nm). Also this campaign counted with a SODAR, a meteorological RADAR specially set up to detect aerosol "echoes" and gas-particle analyzers. To guarantee a good regional coverage 4 distinct sites were available to deploy the instruments, 2 in the near field of biomass burning activities (Rio Claro and Bauru), one for industrial emissions (Cubatao) and others from urban sources (Sao Paulo). The whole campaign provide the equivalent of 30 days of measurements which allowed us to get aerosol optical properties such as backscattering/extinction coefficients, scatter and LIDAR ratios, those were used to

In this 2012 edition, we highlight the growth of gasoline consumption at the expense of ethanol, compared with previous years. The fall harvest of cane sugar and federal policies aimed at artificially support the price of gasoline are some of the factors that led to the fall in competitiveness of ethanol. Nowadays, it is up to the government to create policies to stimulate the supply of renewable fuels to replace fossil fuels. (author)

  7. Indoor organic and inorganic pollutants: In-situ formation and dry deposition in Southeastern Brazil

    Science.gov (United States)

    Allen, Andrew G.; Miguel, Antonio H.

    We have measured indoor and outdoor levels of particle- and gas-phase pollutants, collected in offices, restaurants and a hotel at six different sites in and around the cities of São Paulo and Campinas, Brazil, during summer 1993. Gas-phase species included acetic acid, formic acid, nitrous acid, hydrochloric acid, sulfur dioxide, nitric acid, oxalic acid, and pyruvic acid. Fine mode ( 3 μm dp) species measured included chloride, potassium, acetate, nitrate, magnesium, formate, sodium, pyruvate, nitrite, calcium, sulfate, oxalate, and ammonium. One sample (˜ 6 h) was simultaneously collected indoors and outdoors at each site during regular working hours. Indoor samplers were located ca. 1.5 m from the floor, and the outdoors immediately outside the window. Indoor/outdoor concentration ratios suggest that fine potassium chloride was produced indoors in appreciable amounts at both restaurants studied and, to a lesser extent, in the three offices as well. Indoor fine nitrate particles found in restaurants appear to have been produced by fuel combustion; a small fraction may have resulted from dry deposition of nitric acid onto existing fine particles. Indoor and outdoor concentrations of fine- and coarse-mode acetate suggest their production at all sites. The average concentration of gas-phase acetic acid was 42 μg m -3 indoors compared to 9.0 μg m -3 outdoors. In-situ formation of nitrous acid and acetic acid appears to have occurred at all indoor sites. High levels of formic and acetic acids were produced indoors at a pizzeria that used wood for cooking. Nitrous acid average concentrations for all sites were 8.4 μm m -3 indoors and 3.2 μm m -3 outdoors. Indoor/outdoor ratios at all sites suggest that dry deposition indoors may have occurred for hydrochloric acid, nitric acid and sulfur dioxide and that fine-mode sulfate infiltrate buildings from outside at most sites.

Sixty percent of 10,176 patients, from 239 cities, were serologically reactive to P. brasiliensis. The cities that showed the most serological reactivity among patients were São João da Boa Vista (85%, Piracicaba (75%, Sorocaba (73%, Campinas (72% and São Paulo (62%. São Paulo state has an area of 248,209.4 km²; the climate is tropical and sub-tropical with annual temperatures between 18 and 24ºC, high rainfall (900 to 1800 mm/year, rainy summers and mild winters. It also features large areas composed of acidic soils, and is one of the greatest contributors to Brazilian agricultural production and, separately, the largest producer of orange juice and, the ninth greatest producer of soy and sugar cane and the fourth largest coffee producer. We suggest that the climatic characteristics associated with soil type and development of primary activities can contribute to the endemic potential of PCM in São Paulo state.

    Full Text Available OBJETIVO: Analisar dados coletados pela Pesquisa Nacional de Demografia e Saúde, de 1996, sobre o uso de métodos anticoncepcionais no Estado de São Paulo, Brasil. MÉTODOS: Os dados obtidos foram analisados comparativamente com os do Brasil e com os de outra pesquisa similar realizada em 1986. Foi examinado o uso de métodos anticoncepcionais entre mulheres não-solteiras (casadas ou em coabitação, focalizando-se idade, número de filhos, escolaridade, idade na esterilização feminina e momento da esterilização. Para análise estatística, utilizaram-se o teste t-Student e o teste não-paramétrico de Kendall. RESULTADOS: Diferentemente do Brasil, houve estabilização dos índices de esterilização feminina no Estado de São Paulo no período estudado. Observou-se um mesmo padrão de uso de métodos no Brasil e em São Paulo: até os 30 anos, o método predominante foi a pílula; e, depois dos 30 anos, predominou a esterilização feminina, que aumenta com o número de filhos e diminui com a escolaridade. O uso de métodos masculinos aumentou nos últimos anos, sendo maior em São Paulo, que também apresenta maior diversidade no uso de métodos reversíveis. CONCLUSÕES: Apesar das diferenças, o uso predominante de apenas dois métodos anticoncepcionais, em São Paulo e no Brasil, reflete distorções na oferta do planejamento familiar e na saúde reprodutiva no contexto da nova regulamentação do planejamento familiar.OBJECTIVE: To analyze data on contraceptive use in the State of São Paulo, Brazil, collected by the Demographic and Health Survey (DHS conducted in 1996.

    Conventional tillage usually imposes a variety of modifications on soil properties that can lead to important changes in the type and magnitude of the hydrological processes that take place at the upper portion of the soil profile. Plough pan formation, for example, is considered to be an important consequence of conventional tillage practices in southeastern Brazil, decreasing infiltration rates and contributing to soil erosion, especially in steep slopes. In order to characterize the changes in soil properties and soil hydrology due to the plough pan formation we carried out detailed investigations in two experimental plots in Paty do Alferes region, located in the hilly landscape of Serra do Mar in southeastern Brazil, close to Rio de Janeiro city. Farming activities are very important in this area, in particular the ones related to the tomato production. The local hilly topography with short and steep hillslopes, as well as an average annual rainfall of almost 2000 mm, favor surface runoff and the evolution of rill and gully erosion. The two runoff plots are 22m long by 4m wide and were installed side by side along a representative hillslope, both in terms of soil (Oxisol) and steepness. At the lower portion of each plot there is a collecting trough connected by a PVC pipe to a 500 and 1000 liters sediment storage boxes. Soil tillage treatments used in the two plots were: Conventional Tillage (CT), with one plowing using disc-type plow (about 18 cm depth) and one downhill tractor leveling, in addition to burning residues from previous planting; and Minimum Tillage (MT), which did not allow burning residues from previous planting and preserved a vegetative cover between plantation lines. Runoff and soil erosion measurements were carried out in both plots immediately after each rainfall event. In order to characterize soil water movements under the two tillage systems (CT and MT), 06 nests of tensiometers and 04 nests of Watermark sensors were installed in each

    Symptoms of huanglongbing (HLB), one of the most serious diseases of citrus in Asia and Africa, have been noticed in March 2004 in the Araraquara region of São Paulo State, Brazil. HLB has not been reported previously from America. The causal HLB bacteria, Candidatus Liberibacter africanus in Africa and Candidatus Liberibacter asiaticus in Asia, can be detected in symptomatic citrus leaves by PCR amplification of their 16S rDNA with previously described primers. When this technique was applied to 43 symptomatic leaf samples from the Araraquara region, all PCR reactions were negative. This suggested that a new pathogen, not detected by the above primers, could be involved in HLB in the State of São Paulo. Indeed, by using universal primers for amplification of bacterial 16S rDNA, a new liberibacter species, Candidatus Liberibacter americanus, has recently been identified. Specific primers for PCR amplification of the 16S rDNA of Ca. L. americanus have been selected. Using these primers, the new liberibacter could be detected in 214 symptomatic leaf samples tested. The leaves of two additional samples were infected with Candidatus Liberibacter asiaticus, and two further samples contained both Ca. L. americanus and Ca. L. asiaticus. The samples came from 47 farms in 35 municipalities. The psyllid vector of Ca. L. asiaticus, Diaphorina citri, is established in South, Central, and North America (Florida and Texas). Ca. L. americanus could be detected by PCR in several batches of D. citri psyllids collected on symptomatic sweet orange trees infected with Ca. L. americanus, strongly suggesting that D. citri is the vector of Ca. L. americanus. The results reported here confirm the presence of HLB in the State of São Paulo. Ca. L. americanus is the most widely distributed pathogen.

    From May 2007 to March 2008, blood samples were collected from 92 healthy dogs living in 21 households (17 farms in rural area, and 4 homes in urban area) in 6 counties of the State of Espírito Santo, southeastern Brazil. In addition, ticks were collected from these dogs. A mean of 4.4+/-3.0 dogs (range: 1-12) were sampled per household; 78 and 14 dogs were from rural and urban areas, respectively. Polymerase chain reaction (PCR) designed to amplify fragments of the 18S rDNA gene of Babesia spp or Hepatozoon spp revealed amplicons of the expected size in 20 (21.7%) dogs for Babesia, and 54 (58.7%) dogs for Hepatozoon. All Babesia-positive dogs were also Hepatozoon-positive. Among the 21 households, 15 (71.4%) from 3 counties had at least one PCR-positive dog, including 13 farms (rural area) and 2 homes (urban area). A total of 40 PCR products from the Hepatozoon-PCR, and 19 products from the Babesia-PCR were submitted to DNA sequencing. All generated sequences from Hepatozoon-PCR were identical to each other, and to corresponding 18S rDNA sequences of H. canis in GenBank. Surprisingly, all generated sequences from the Babesia PCR were also identical to corresponding 18S rDNA sequences of H. canis in GenBank. Dogs from 10 rural and 2 urban households were found infested by Rhipicephalus sanguineus ticks. Immature of Amblyomma cajennense ticks were found in dogs from only 4 rural households (also infested by R. sanguineus). All but one household with R. sanguineus-infested dogs had at least one Hepatozoon-infected dog. Statistical analysis showed that the presence of ticks (i.e. R. sanguineus) infesting dogs in the households was significantly (P0.05) between PCR-positive dogs and urban or rural households. Canine hepatozoonosis caused by H. canis is a high frequent infection in Espírito Santo, Brazil, where it is possibly vectored by R. sanguineus. Since all infected dogs were found apparently healthy, the pathogenicity of H. canis for dogs in Espírito Santo is

    Full Text Available Smectitic clay minerals are frequently identified in mangrove soils, but there is little information about their types and origins. Besides their importance in the agronomical and geotechnical areas, smectites play an important environmental role by adsorbing nutrients, organic pollutants and heavy metals. Smectites found in mangrove soils can be of marine or continental detrital origin, or of neoformation origin. Thus, the objective of this study was to identify the types of smectites present in the State of São Paulo mangrove soils (Brazil, and to relate them to their possible origins. Soil samples were taken in five mangroves along the State of Sao Paulo State coast line. The mineral composition of the clay fraction was identified by X-ray Diffractometry (XRD applying the Greene-Kelly test and by Fourier transform infrared spectroscopy (FTIR. Highlighting the peaks in the 3,560 cm-1 band and in the region near 798 and 820 cm-1, there was a predominance of nontronite in the soil at the Sítio Grande River, Pai Matos Island, Caranguejo Island and Itapanhaú River mangroves, and possibly a lower concentration of ferric montmorillonite in the Escuro River mangrove. Since the continental sediments in these environments are very poor in smectite, the origin of these minerals in the mangrove soils studied is related to sedimentation left by past marine transgressions, to neoformation processes, or yet to a combination of both origins.Minerais de argila esmectíticos são freqüentemente identificados em solos de manguezais, mas são escassas as informações sobre os tipos encontrados e suas origens. A despeito da importância para a agronomia e geotecnia, as esmectitas desempenham também importante papel no âmbito ambiental, atuando na adsorção de nutrientes, poluentes orgânicos e metais pesados. Esmectitas em solos de manguezais podem ser de origem detrítica, marinha ou continental, e também de neoformação. Assim, este estudo objetivou

    Full Text Available ABSTRACT In Brazil, the Mantiqueira Range, southeastern region, shelters the last remnants of the ecologically important Upper Montane Tropical Forest. since extensive exploration that has been taking place in this biome for decades, the influence of land-use changes on hydropedology in these areas must be investigated once major land-use changes have been observed. This study aims to evaluate the land-use influence on soil drainable porosity (SDP in a headwater watershed located in the Mantiqueira Range region, and to validate the proposed methods based on micromorphological and hydrological indicators. The native vegetation of the study area is Atlantic forest that occupies 62% of the area, and the remaining 38% has been used for pasture. Thirty nine combinations of environmental variables were tested, each one generating a map for predicting SDP. The performance of the spatial prediction of SDP was assessed using 20% of the data from the total number of samples collected throughout the watershed. The least values of SDP are due to the process of removal of native forest and replacement by pasture. Areas with high to moderate SDP are associated with native forest fragments demonstrating the effects of the Atlantic Forest on the water infiltration and groundwater recharge processes, given by the greater contribution of baseflow in a forested catchment located within the studied watershed. The analysis of soil micromorphological images provided useful supporting information on the soil porosity system and along with hydrological properties of the watershed helped understand the SDP behavior on subsurface and groundwater storage capacity.

    Full Text Available Pomadasys corvinaeformis inhabits sandy and rocky bottoms in coastal waters, and is common in trawl samples taken from beaches. The species is very abundant on the Brazilian coast, and is of high economic and ecological importance. This study examined the spatio-temporal distribution, population biology and diet of P. corvinaeformis in Southeastern Brazil. Samples were taken by trawling monthly from August 2003 to October 2004, in two previously selected areas. The Northern area is more exposed to wave activity and is influenced by a river, functioning as a small estuary. In contrast, the Southern area is relatively sheltered from wave energy and influenced to a lesser degree by smaller rivers. The length of the specimens was measured, and the sex and gonadal stage were macroscopically identified. The abundance of this species was compared between areas and among months. The diet was analyzed seasonally by the frequency of occurrence, the percent volume, and the index of alimentary importance. P. corvinaeformis occurred in unequal proportions in the two study areas 86 in the Northern area and 14 in the Southern area and was found most abundant in May 2004, followed by June 2004. The proportion of mature and in-maturation individuals increased gradually from autumn to summer. Nine major groups of food items were recorded in the diet of P. corvinaeformis, and crustaceans comprised five of the categories: unidentified crustacean fragments, zoea larvae, amphipods, copepods and shrimps. In both, fish stomach and intestine, crustacean fragments were the most frequent item. The second most frequent items were shrimp in the stomach, and amphipods in the intestine mainly represented by their tubes. These results demonstrate that P. corvinaeformis can be considered a carnivore, with a preference on benthic organisms.

    To analyze the spatial distribution of reported AIDS cases in adults and its association with living conditions in the city of Campinas, Southeastern Brazil. Data on AIDS cases in men (n=2,945) and women (n=1,230) aged more than 13 years and living in Campinas, recorded in the SINAN (Brazilian Information System for Notifiable Diseases), were used to map the spatial distribution of this disease and the male:female ratio. Maps were constructed for the following periods: from 1980 to 1995, from 1996 to 2000, and from 2001 to 2005. The variables included in the analysis were address, sex and age. A weighted composite index was used to study living and health conditions in the area. Patients' home addresses were geocoded on a cartographic base, after correction and standardization according to a reference database of streets. A generalized additive model was adjusted to analyze the spatial distribution of the ratio of male:female cases in space, in the three study periods. The ratio of male:female cases was higher in areas with better living conditions (central) and around the prison (northwestern), where families of prisoners and former prisoners live temporarily, while this ratio was lower in the city suburbs (southwestern). The trends towards the AIDS epidemic affecting more women and poorer individuals were confirmed by the decrease in the ratio of male:female cases in the period, particularly in vulnerable and impoverished populations. Geographic information systems and spatial data analysis can be useful for AIDS control and surveillance actions.

    Full Text Available This paper evaluates the post-dispersal artificial seed predation rates in two areas of the southeastern Amazon forest-savanna boundary, central Brazil. We conducted the survey in a disturbance regime controlled research site to verify if exists an edge effect in these rates and if the disturbance (in this case annual fire and no fire affects seed predation. We placed 800 peanuts seeds in each area at regular distance intervals from the fragment`s edge. Data were analyzed by a likelihood ratio model selection in generalized linear models (GLM. The complete model (with effects from edge distance and site and its interaction was significative (F3=4.43; p=0.005. Seeds had a larger predation rates in fragment’s interior in both areas, but in the controlled area (no disturbance this effect was less linear. This suggests an edge effect for post-dispersal seed predation, and that disturbances might alter these effects. Even if we exclude the site effect (grouping both areas together there is still a strong edge effect on seed predation rates (F3=32.679; p>0.001. We did not verify predator’s species in this study; however, the presence of several species of ants was extremely common in the seeds. The detection of an edge effect in only a short survey time suggests that there is heterogeneity in predation rates and that this variation might affect plant recruitment in fragmented areas of the Amazon forest. Henceforth, this seed predation should be taken in consideration in reforestation projects, where the main source of plants species is from seed distribution.

    Full Text Available Beta diversity patterns are the outcome of multiple processes operating at different scales. Amphibian assemblages seem to be affected by contemporary climate and dispersal-based processes. However, historical processes involved in present patterns of beta diversity remain poorly understood. We assess and disentangle geomorphological, climatic and spatial drivers of amphibian beta diversity in coastal lowlands of the Atlantic Forest, southeastern Brazil. We tested the hypothesis that geomorphological factors are more important in structuring anuran beta diversity than climatic and spatial factors. We obtained species composition via field survey (N = 766 individuals, museum specimens (N = 9,730 and literature records (N = 4,763. Sampling area was divided in four spatially explicit geomorphological units, representing historical predictors. Climatic descriptors were represented by the first two axis of a Principal Component Analysis. Spatial predictors in different spatial scales were described by Moran Eigenvector Maps. Redundancy Analysis was implemented to partition the explained variation of species composition by geomorphological, climatic and spatial predictors. Moreover, spatial autocorrelation analyses were used to test neutral theory predictions. Beta diversity was spatially structured in broader scales. Shared fraction between climatic and geomorphological variables was an important predictor of species composition (13%, as well as broad scale spatial predictors (13%. However, geomorphological variables alone were the most important predictor of beta diversity (42%. Historical factors related to geomorphology must have played a crucial role in structuring amphibian beta diversity. The complex relationships between geomorphological history and climatic gradients generated by the Serra do Mar Precambrian basements were also important. We highlight the importance of combining spatially explicit historical and contemporary predictors for

    PM. Andrade

    Full Text Available Eriocnema fulva Naudin is an endangered herbaceous, perennial, iteroparous, evergreen species geographically restricted to southeastern-center Minas Gerais State, SE Brazil. The individuals occur as patches on rocky riverbanks shaded by seasonal semideciduous Atlantic forest; they are fixed by roots and have a pending stem. Aiming to investigate leaf development and its importance for individual survival, fifteen contiguous plots (1 x 1 m were set down in Jambreiro Forest (19° 58’-59’ S and 43° 52’-55’ W, 800-1100 m altitude, in the municipality of Nova Lima. A total of 260 individuals with the largest leaf blade length > 1 cm was tagged and measured in 1997, 1998, and 1999. Leaf expansion was recorded each month during 26 months until April 2000. Plant size was measured through leaf blade length, petiole length, stem length, and number of leaves. Significant changes were detected only after two years, thus indicating that plant growth is slow. The proportion of surviving leaves after two years was 60%. Total blade expansion took over 14 months, a slow growth rate when compared to leaves of other tropical forest canopy and understory species. Long leaf lifespans are to be found in plants exhibiting slow growth, and we observed that some leaves lived longer than three years. Petiole growth can help to better position the leaf in the search for light, thus contributing to the growth and survival of the plant. The relationships among size measures were significant, reinforcing the great contribution of leaf size for plant size. The age of the largest individual was estimated as 36 years based on the median annual leaf production rate.

    Full Text Available OBJECTIVE: To assess incidence and predictors of first pregnancy among women with HIV/AIDS. METHODS: Prospective cohort study was conducted in Rio de Janeiro, southeastern Brazil, between 1996 and 2003. This study comprised 225 women with HIV/AIDS followed up until their first pregnancy or first censored event (hysterectomy, tubal ligation, menopause, 50 years of age, loss to follow-up, death or the end of December 2003. Pregnancy and abortion rates were estimated, and Cox proportional hazards models were used to identify baseline characteristics associated with pregnancy risk. RESULTS: The women were followed up for 565 person/years with a median follow-up of 3 years per women. The mean age was 32 years (SD: 7, and 54.7% were white. There were 60 pregnancies in 39 women, and 18 were terminated (induced abortions, accounting for a rate of 6.9% and 2.1% women/year, respectively. Repeated pregnancies occurred in 33.3% of the women (13/39. Higher pregnancy risk was seen among younger women (HR=3.42; 95%CI: 1.69;6.95 and those living with their partners (HR=1.89; 95%CI: 1.00;3.57. Lower pregnancy risk was associated with higher education level (HR=0.43; 95%CI: 0.19;0.99 and use of antiretroviral therapy (HR=061; 95%CI: 0.31;1.17. CONCLUSIONS: Lower pregnancy rates were found in our cohort than in the general population. Sociodemographic characteristics should be taken into consideration in the management of reproductive health in HIV-positive childbearing age women. Reproductive and family planning counseling must be incorporated into HIV/AIDS programs for women to help preventing HIV transmission to their partners and offspring.

    Full Text Available OBJECTIVE: To evaluate density, parity rates, daily survival and longevity of natural populations of Culex quinquefasciatus in three neighborhoods with distinct socio-economic and infrastructure profiles. METHODS: Mosquito collections of the Culex quinquefasciatus species were performed weekly during two four month periods, from August to November 2008 (spring and March to June 2009 (fall, in a favela (slum, a suburban area and a middle class area of Rio de Janeiro, Southeastern Brazil. Collections were performed with backpack aspirators, in 20 randomly selected houses in each area per week, during 15-20 minutes per house. Ovaries were removed from captured females and classified as initial, intermediary or final stage. Furthermore, females were dissected for determination of parity based on the condition of the tracheal system. Mosquito survival rate and longevity were estimated on a per month basis for each neighborhood. RESULTS: We collected a total of 2,062 Culex quinquefasciatus, but monthly vector density was not correlated with temperature and rainfall. We dissected the ovaries of 625 Culex quinquefasciatus, and overall, there was a higher proportion of nulliparous females during the dryer months, while gravid females were more frequent in rainy months. In the middle class neighborhood, the parity rate reached up to 93.75% with survivorship of 0.979. Lower parity and survival rates were obtained in the suburban area (as low as 36.4% parity and 0.711 daily survival. Up to 84.7% of Culex quinquefasciatus females could survive the eight day period needed to complete West Nile Virus incubation. CONCLUSIONS: The survival rate of Culex quinquefasciatus varied significantly between the neighborhoods. This suggests that vectorial capacity and disease transmission risk may vary greatly between different urban areas, which is potentially useful information for vector control programs.

    Several studies show that deep geological formations are the most promising solution - technical and economical - for the safe disposal of the high-level radioactive wastes produced by the nuclear industry. In order to obtain the necessary information to assess on the use of geological sites in Brazil - for the disposal of high-level radioactive waste generated by the brazilian nuclear industry - a careful survey on the basalt and granite rocks of Sao Paulo State was made. The data obtained were evaluated according to guidelines established by the International Atomic Energy Agency. The favourable and unfavourable characteristics of the basalts, granites and their respective occurrence areas in the Sao Paulo state territory - as potential waste disposal sites - were analysed. This preliminary and regional characterization is not a conclusive study whether these two rocks types are definitively the most suitable geological formations for use as nuclear waste repository or not. It is the subsidy for a more detailed analysis. Other factors such as social, political and economical aspects, ecological effects, engineering geology, heat generation rate of the waste, type of radiation emitted and corrosive nature of the waste must also be taken into account.

    The Salto Grande Reservoir is used for electric generation, irrigation, fish farming, recreation and water supply for the region's cities. The reservoir belongs to the city of Americana, located in on the eastern region of Sao Paulo State, Brazil. It belongs to the Piracicaba River Hydrographic Basin, the second most important economic and populated region and one of the most polluted areas in the State. This basin is located in a highly industrialized and agricultural region. Due to urban, industrial and agricultural activities as well as sewage wastes the water and sediments of this reservoir and surroundings are extremely contaminated, mainly by metals, according to CETESB (Environmental Control Agency of the Sao Paulo State). In order to obtain better information about its sediment contamination the present study reports results of the concentration of some major (Ca, Fe, K and Na), trace (As, Ba, Br, Co, Cr, Cs, Hf, Rb, Sb, Se, Ta, Th, U, Zn and rare earth (Ce, Eu, La, Lu, Nd, Sc, Sm, Tb and Yb)) elements in sediments and Cd, Cr, Cu, Ni and Pb concentration in sediments and water from the Salto Grande Reservoir. Multielementar analysis was carried out by Instrumental Neutron Activation Analysis (INAA). Multielemental concentrations in the sediment samples were compared to NASC (North American Shale Composite) values. The concentration values for metals As, Cd, Cr, Cu, Pb, Ni and Zn were compared to the Canadian Council of Minister of the Environment (CCME) oriented values (TEL and PEL) and adopted by CETESB, (author)

    Full Text Available Although preliminary surveys have been conducted at the Atlantic Forest of Ubatuba, there is no list of documented bird records from this coastline municipality. To organize such a compilation, we searched the literature and a number of different sources for all documented records of birds from Ubatuba, state of São Paulo. We further carried out a 7-year non-systematic bird inventory in different regions and elevations to document the species within the municipality. The total number of documented bird species is 417, 11% of which are endemic to Brazil. Another 26% are Atlantic Forest endemics and as many as 60 species are under threat categories, including near-threatened birds, in the state. Some 49 species of 27 families are reported from the municipality but still lack documentation. Considering historical records, no species have extinguished from the municipality. Ubatuba is one of the most studied regions along Serra do Mar in São Paulo regarding its ornithology, but there are still high-elevational gaps that will yield significant additions of species to the area with increasing surveying efforts.

    A feasibility study has been performed on the energy conservation project aimed at the future CDM in relation with energy consumption in the lighting equipment at the Sao Paulo state primary schools in the Federative Republic of Brazil. Out of about 5,500 primary schools existing in Sao Paulo, 3,414 schools were selected as the objects of the surveys and discussions. The present program intends to introduce energy saving facilities such as high-efficiency fluorescent lamps and controls for illuminating the primary schools to save the energies and reduce emission of the global warming gases. In this economy project, the owners do not need to make initial investments, wherein the required funds are taken care by conservation of electric power during the service contract period. If about 3,000 schools are selected as the object, a fund of about 2.3 billion yen will be required in total. Total energy conservation quantity during 15 years from 2002 to 2016 as achieved by this project will be 532,740 MWh, corresponding to 114,540 tons of crude oil. The effect of reducing the emission of global warming gases will be 110,949 t-CO2 during the same period of time. (NEDO)

    The Salto Grande Reservoir is used for electric generation, irrigation, fish farming, recreation and water supply for the region's cities. The reservoir belongs to the city of Americana, located in on the eastern region of Sao Paulo State, Brazil. It belongs to the Piracicaba River Hydrographic Basin, the second most important economic and populated region and one of the most polluted areas in the State. This basin is located in a highly industrialized and agricultural region. Due to urban, industrial and agricultural activities as well as sewage wastes the water and sediments of this reservoir and surroundings are extremely contaminated, mainly by metals, according to CETESB (Environmental Control Agency of the Sao Paulo State). In order to obtain better information about its sediment contamination the present study reports results of the concentration of some major (Ca, Fe, K and Na), trace (As, Ba, Br, Co, Cr, Cs, Hf, Rb, Sb, Se, Ta, Th, U, Zn and rare earth (Ce, Eu, La, Lu, Nd, Sc, Sm, Tb and Yb)) elements in sediments and Cd, Cr, Cu, Ni and Pb concentration in sediments and water from the Salto Grande Reservoir. Multielementar analysis was carried out by Instrumental Neutron Activation Analysis (INAA). Multielemental concentrations in the sediment samples were compared to NASC (North American Shale Composite) values. The concentration values for metals As, Cd, Cr, Cu, Pb, Ni and Zn were compared to the Canadian Council of Minister of the Environment (CCME) oriented values (TEL and PEL) and adopted by CETESB, (author)

    Full Text Available A large epidemic of serogroup B meningococcal disease (MD, has been occurring in greater São Paulo, Brazil, since 1988.21 A Cuban-produced vaccine, based on outer-membrane-protein (OMP from serogroup B: serotype 4: serosubtype P1.15 (B:4:P1.15 Neisseria meningitidis, was given to about 2.4 million children aged from 3 months to 6 years during 1989 and 1990. The administration of vaccine had little or no measurable effects on this outbreak. In order to detect clonal changes that could explain the continued increase in the incidence of disease after the vaccination, we serotyped isolates recovered between 1990 and 1996 from 834 patients with systemic disease. Strains B:4:P1.15, which was detected in the area as early as 1977, has been the most prevalent phenotype since 1988. These strains are still prevalent in the area and were responsible for about 68% of 834 serogroup B cases in the last 7 years. We analyzed 438 (52% of these strains by restriction fragment length polymorphism (RFLPs of rRNA genes (ribotyping. The most frequent pattern obtained was referred to as Rb1 (68%. We concluded that the same clone of B:4:P1.15-Rb1 strains was the most prevalent strain and responsible for the continued increase of incidence of serogroup B MD cases in greater São Paulo during the last 7 years in spite of the vaccination trial.

    Food environment and income act as determinants of diet, and consequently, of the consumption of fruits and vegetables. The objective of this study is to investigate the association between fruit and vegetable consumption, income, and street market density in adolescents living in São Paulo, Brazil. Data from 521 adolescents (12 to 19 years) participating in the 2015 Health Survey of São Paulo were used. Buffers (500, 1000, and 1500 m) were drawn around the households and the street markets were counted in each zone. Multilevel logistic regression models were used to evaluate the association between fruit and vegetable consumption, income, and street market density. The main results showed that the presence of a street market in the zone closest to the households (500 m) was associated with higher consumption of fruits and vegetables (OR: 1.73; CI 95% 1.01–3.00). Higher family income was associated with a higher consumption of fruits and vegetables for models of 500 m buffer (OR: 2.56; CI 95% 1.47–4.45), 1000 m (OR: 2.30; CI 95% 1.33–3.96), and 1500 m (OR: 2.32; CI 95% 1.35–4.00). These results support the implementation of public policies that jointly consider income and the availability of street markets or healthy food environments. PMID:29538324

    Teenage pregnancy is a common public health problem worldwide. The objective of this ecological study was to investigate the spatial association between teenage pregnancy rates and socioeconomic characteristics of municipalities in São Paulo State, Southeast Brazil. We used a Bayesian model with a spatial distribution following a conditional autoregressive (CAR) form based on Markov Chain Monte Carlo algorithm. We used data from the Live Birth Information System (SINASC) and the Brazilian Institute of Geography and Statistics (IBGE). Early pregnancy was more frequent in municipalities with lower per capital gross domestic product (GDP), higher poverty rate, smaller population, lower human development index (HDI), and a higher percentage of individuals with State social vulnerability index of 5 or 6 (more vulnerable). The study demonstrates a significant association between teenage pregnancy and socioeconomic indicators.

    Full Text Available The present study surveyed the profile of people who did or did not take part in programs and activities in primary healthcare units in the Butantã district, the city of São Paulo, Brazil. The rationale for the study was the concept of body practice understood as a practice of health and care. A semi-structured questionnaire was applied to 1090 individuals mostly middle-aged housewives. Only 5.78% of respondents were enrolled in some program and activities, mainly walking and stretching. There was a consensus between participants and non-participants on the importance of initiatives geared to care for the body and attention to health. The difficulties for having access to programs and the lack of options in the health public service were pointed out as the main obstacles for a greater involvement by local population.

    This paper presents the methodology and results obtained with radioactive tracer techniques as applied to study sea-bottom sediments movements off a stretch of the southern coast of Sao Paulo State, Brazil, namely Praia do Una. Three injections of ground glass containing Iridium-192 were made and the behaviour of this material was tracked by special detection techniques, as it was acted upon by hydrodynamic agents, in two distinct periods of the year of 1982 (summer and winter). Measurement of hydrodynamic parameters was conducted simultaneously with tracer experiments. From the experiments with radioactive tracers, combined with other conventional studies, qualitative and quantitative conclusions could be drawn, as follows: waves are the prevailing agents in moving bottom sediments; during summer time, onshore and alongshore transport can be identified; during winter time, offshore and alongshore transport are present; for summer conditions, Massif transport rate was estimated to be 150 kg m -1 day -1 .

    : Aleyrodidae infesting vegetables and ornamental plants in some localities of São Paulo State, Brazil, has been observed. High densities of this insect were verified on tomato, broccoli, egg-plant and squash; in some cases, tomato and squash presented the whitefly-related disorders named tomato irregular repening and squash silverleaf. Weeds, mainly Sida rhombifolia L., Sonchus oleraceus L., Solanum viarum Dun. and Ipomoea acuminata Roem. & Schult., showed high whitefly colonization. At the Holambra county intensive colonizations were recorded on or-namental plants, mainly Chrysanthemum morifolium Ramat. and Euphorbia pulcherrima Willd. (poinsettia. Daily insecticide applications did not reduce the insect infestations. Other crops, such as bean and cotton, were also infested. The disorders and type of infestations are similar to what has been observed in the U.S.A. In this country, the ability of certain populations of B. tabaci to induce the silverleaf disorder of squash and to colonize poinsettia intensely, among other characteristics, has been used to distinguish the "poinsettia strain" or "B strain". However, based on genomic and crossing/mating behavior studies, some investigators have considered that these two strains represent different species. In view of the similarity of the infestations and disorders that are occurring in the U.S.A., and more recently in São Paulo State, it is very likely that the "B strain" (or the new species has been introduced in Brazil.

    Since 2003, the access to medication has been increasing in Brazil and particularly in São Paulo. The present study aimed to analyze the access to medication obtained in the public sector and the socioeconomic differences in this access in 2003 and 2008. Also, we explored the difference in access to medication from 2003 to 2008. Data were obtained from two cross-sectional population-based household surveys from São Paulo, Brazil (ISA-Capital 2003 and ISA-Capital 2008). Concentration curve and concentration index were calculated to analyze the associations between socioeconomic factors and access to medication in the public sector. Additionally, the differences between 2003 and 2008 regarding socioeconomic characteristics and access to medication were studied. Access to medication was 89.55% in 2003 and 92.99% in 2008, and the proportion of access to medication did not change in the period. Access in the public sector increased from 26.40% in 2003 to 48.55% in 2008 and there was a decrease in the concentration index between 2003 and 2008 in access to medication in the public sector. The findings indicate an expansion of Brazilian Unified Health System (Sistema Único de Saúde ) users, with the inclusion of people of higher socioeconomic position in the public sector. As the SUS gives more support to people of lower socioeconomic position in terms of medication provision, the SUS tends to equity. Nevertheless, universal coverage for medication and equity in access to medication in the public sector are still challenges for the Brazilian public health system.

    We estimate the proportion of psychotropic medication use (PMU) among adults in São Paulo Metropolitan Area, Brazil. We investigated whether socio-demographic factors, comorbidity, and disease severity influence PMU among individuals with psychiatric disorders. Data are from the São Paulo Megacity Mental Health Survey, a cross-sectional, population-based study, the Brazilian branch of the World Mental Health Survey Initiative. Trained lay interviewers face-to-face assessed psychiatric disorders and PMU through the Composite International Diagnostic Interview. Respondents were asked about use of healthcare service and prescribed medications for mental disorders in the previous year. Information on PMU was collected for 2935 adult residents in the area and among those with disorders who received treatment. Around 6% of respondents reported PMU in the past year: hypnotics or sedatives were used by 3.7% and antidepressants by 3.5%. Among individuals with 12-month disorders, only 14% reported past year PMU. Gender, age, education, income, occupational status, comorbidity, and severity were significant predictors for PMU. Among those with 12-month DSM-IV disorders who obtained treatment in healthcare settings, almost 40% received medication only. Among those treated in specialty mental health service, around 23% received combination of medication and psychotherapy. Our study has pointed out that the recent trend of access to mental healthcare in Brazil depicts unmet needs, characterized by a low prevalence of PMU among individuals with psychiatric disorders. Policies that improve appropriate access to prescribed drugs for those most in need are urgent public health priority. Copyright © 2015 John Wiley & Sons, Ltd.

    Phurcalite has been found filling fractures in the tourmaline-bearing granitic pegmatite of Perus, in the north-west part of Sao Paulo city, Brazil. It forms aggregates of radiating euhedral crystals up to 5 mm in length. The crystals are bright yellow, transparent and display vitreous to adamantine lustre. Its streak is pale yellow. Phurcalite is brittle, with a conchoidal fracture, and non-fluorescent. The crystal structure of phurcalite has been solves by single-crystal x-ray diffraction methods and refined to R = 3.8% using 2065 observed [I > 3{sigma}(I)] reflections. The structure consists of [(U O{sub 2}){sub 3} O{sub 2} (P O{sub 4}){sub 2} {sup 4n-}]{sub n} layers, parallel to (010), connected by Ca{sup 2+} ions and H{sub 2} O. The coordination polyhedra are: for U(1) hexagonal bi pyramid; for U(2) and U(3) pentagonal bi pyramids; for Ca(4) and Ca(5) capped trigonal prism and triangulated dodecahedron, respectively; and for P(6) and P(7) tetrahedra. As a consequence of this work, the molecular formula of phurcalite previously reported as Ca{sub 2} (U O{sub 2}){sub 3} (P O{sub 4}){sub 2} (OH){sub 4}.4 H{sub 2} O must be changed to Ca{sub 2} (U O{sub 2}){sub 3} O{sub 2} (P O{sub 4}){sub 2}.7 H{sub 2} O. Other secondary uranium minerals associated with Perus phurcalite are autunite, torbernite, meta-autunite, meta-torbernite, chernikovite, meta-uranocircite I, phosphuranylite, uranophane-alpha, uranophane-beta, haiweeite, barian week site and perhaps also bassetite, meta-tyuyamunite and meta-haiweeite. Opal, tridymite, cristobalite, secondary quartz, saponite and rhodochrosite occur associated to the uranium minerals. (author).

    Full Text Available Bothrops jararacussu is a terrestrial snake, predominantly nocturnal, and mainly found in forested areas. Our objective was to provide the first record of B.jararacussu for the municipality of São Paulo, in the highland of Parque Estadual da Serra do Mar (PESM, Núcleo Curucutu. The register ocurred through monthly samplings in the Núcleo Curucutu, during one year. The specimen was found in a transitional area of Atlantic upper montane forest and Pinus sp. reforestation. It represents a new altitude record (>800m in a well-preserved area, reiterating the importance of this park for the maintenance of biodiversity in this municipality and evinces the region potential to house rare species in São Paulo highland.

    The study of lanthanide distribution in urban environments has become of interest over the last years, due to the increased industrial use of these elements. Sao Paulo is the 6th largest metropolitan region of the world, with about 20 million inhabitants in its metropolitan area, more than 9 million motor vehicles and intense industrial activity. There is little information on U, Th, and lanthanide contents in urban soils, and there are as of yet no reference values for these elements in soils of Sao Paulo city. The present study aimed to determine U, Th and lanthanide concentrations in soils adjacent to avenues of highly dense traffic downtown in Sao Paulo city, to assess their possible sources and potential environmental impacts. The analytical technique employed was Instrumental Neutron Activation Analysis (INAA). Th and U levels ranged from 4.0 to 37.0 mg kg -1 and from 1.6 to 18.7 mg kg -1 , respectively. These values are higher than literature values for U and Th in Brazilian superficial soils. The results obtained for the lanthanides indicate enrichment in La and Ce. However, a possible anthropogenic source should be investigated since high background values of these elements may be associated to the natural geological composition of the soils. (author)

    Noise is the most common agent of occupational exposure. It may induce both auditory and extraauditory dysfunction and increase the risk of work accidents. The purpose of this study was to estimate the fraction of accidents attributable to noise occupational exposure in a mid-size city located in southeastern Brazil. In this population case-control study, which included 108 cases and 324 controls, the incidence rate ratio of work accidents controlled for several covariables was obtained by classifying occupational noise exposure into three levels, as well as determining the prevalence in each level. Based on these data, the attributable fraction was estimated as 0.6391 (95% CI = 0.2341-0.3676), i.e., 63% of the work accidents that took place in the study site were statistically associated with occupational noise exposure. The causes of this association as well as its implications in the prevention of work accidents are discussed.

    Full Text Available Daoism is a religion of Chinese origins that since the 19th century started to have contact with the Brazilian culture, beneath the Orientalism force.  Since the second half of the 20th century, we see a second wave of Daoism spread, albeit indirectly. In the 1970s the Wǔ family – Wu Jyh Cherng within them (Wǔ Zhìchéng – migrates from Taiwan to Rio de Janeiro, Brazil. In the 1990s, this Taiwanese naturalized Brazilian priest of the Way of the Celestial Masters founded the Daoist Society of Brazil (Sociedade Taoísta do Brasil - STB along Brazilians, and later the Daoist Society in São Paulo (Sociedade Taoísta SP - ST-SP, which is our object of study. The goal here was to analyze the Daoism transplantation process in Brazil through the STB and ST-SP. In addition to a systematization of the authors regarding the transplantation of religions theory, we were based on the theory of cultural hybridization, and a set of interpreters of Brazilian culture and Brazilian religion. We created the central hypothesis that in the STB and ST-SP the Daoism would be increasingly a hybrid result of the Brazilian religious matrix and an ideal model of Daoist linked to China. Methodologically, we conducted an extensive and constant literature review, and we refer to primary printed sources, virtual and audiovisual sources, participatory research, semi-structured interviews and informal conversations. With these data, we performed an analysis using the theoretical framework, which allowed us to confirm the central hypothesis. We also wove systematic contributions on: the presence and the type of Daoism entry in Brazil, identification of socio-historical phases of STB and ST-SP, and several observations about the process and results of transplantation of this Daoist group, such as the accommodation of the Brazilian religious demands on the liturgical rituals of these institutions.

    The Ipanema alkaline-carbonatitic complex is part of the Meso-Cenozoic alkaline magmatism located within the southeastern part of the Brazilian Platform. Drill-core and field sampling have indicated the occurrence of glimmerites, with subordinate shonkinites (mela-syenites), clinopyroxene-bearing glimmerites, diorites and syenites. The glimmerites are cross-cut by lamprophyric dykes and calciocarbonatites. Fenitization has deeply affected the country rocks, originating dioritic and syenitic rocks. The Ipanema rocks show a distinct potassic affinity. The initial Sr-Nd- isotopic composition of the Ipanema rocks (87Sr/86Sr = 0.70661-0.70754 and 143Nd/144Nd = 0.51169-0.51181) is similar to that of tholeiitic and potassium-rich-alkaline rocks of the Eastern Paraguay. Stable isotope data for the Ipanema calciocarbonatite suggest interaction with fluids at temperatures typical of hydrothermal stages, as hypothesized for other carbonatite complexes from southeastern Brazil. The chemical differences between the lamprophyre, glimmerites, carbonatites, apatitites and magnetitites, and the absence of marked REE enrichment in the evolved lithologies, all indicate that fractional crystallization and accumulus of liquidus phases in a magma reservoir, likely coupled with liquid immiscibility processes, may have played an important role in the genesis of the Ipanema rocks.

    A combined method for evaluating radon ( 222 Rn) and progeny ( 214 Pb and 214 Bi) in water was developed by using inexpensive alpha scintillation counting and gamma ray spectrometry through NaI(Tl) scintillation detectors. A groundwater sample collected at the Pocos de Caldas alkaline massif in Brazil was submitted to the technique in order to assure its applicability by comparing the volumetric activities by different methods. Similar volumetric activity was determined for 214 Pb and 214 Bi in the sample analyzed that is compatible with the expected condition of radioactive equilibrium between these nuclides. The combined method was successfully used to analyze groundwater samples from Guarani aquifer in Sao Paulo State, Brazil, and the results of the measurements indicated that 214 Pb and 214 Bi provide useful information concerning the evaluation of the drinking water quality in terms of radiological aspects. This is because they are directly identified in the water samples, without the need of requiring the assumption of the establishment of the transient equilibrium condition with its parent 222 Rn

    Many water-supply systems in South America utilize the waters of the Guarani aquifer at least as part of their networks. However, there is little present knowledge in Brazil of the factors affecting Rn presence in the water supplied for end-users, despite the economic importance of Guarani aquifer. 222 Rn analyzes of 162 water samples were performed at 8 municipalities in Sao Paulo State, Brazil, with the aim of investigating the major factors affecting its presence in solution. The 222 Rn activity concentration ranged from 0.04 up to 204.9 Bq/L, with three samples exceeding the World Health Organization maximum limit of 100 Bq/L. Aeration was confirmed as the most important factor for Rn release, as expected due to its gaseous nature. Accumulation in pipes and stratification in the water column were other significant factors explaining the data obtained in some circumstances. The Rn daughters 214 Pb and 214 Bi were also determined in a set of selected samples and their presence was directly related to the occurrence of Rn dissolved in water

    In Brazil, there is a lack of combined soil-plant data attempting to explain the influence of specific climate, soil conditions, and crop management on heavy metal uptake and accumulation by plants. As a consequence, soil-plant relationships to be used in risk assessments or for derivation of soil screening values are not available. Our objective in this study was to develop empirical soil-plant models for Cd, Cu, Pb, Ni, and Zn, in order to derive appropriate soil screening values representative of humid tropical regions such as the state of São Paulo (SP), Brazil. Soil and plant samples from 25 vegetable species in the production areas of SP were collected. The concentrations of metals found in these soil samples were relatively low. Therefore, data from temperate regions were included in our study. The soil-plant relations derived had a good performance for SP conditions for 8 out of 10 combinations of metal and vegetable species. The bioconcentration factor (BCF) values for Cd, Cu, Ni, Pb, and Zn in lettuce and for Cd, Cu, Pb, and Zn in carrot were determined under three exposure scenarios at pH 5 and 6. The application of soil-plant models and the BCFs proposed in this study can be an important tool to derive national soil quality criteria. However, this methodological approach includes data assessed under different climatic conditions and soil types and need to be carefully considered.

    The fission-track method (FTM) in apatite was applied to 45 samples collected in the Serra da Mantiqueira (Mantiqueira mountain range), the Serra do Mar (Mar mountain range), regions next to these mountain ranges and the coastal region between Ubatuba and Santos in the State of Sao Paulo, Brazil, to study the thermochronology of the South American Platform in southeast Brazil and its influence on Santos and Campos basins. The data presented in this work complement the previously presented data on the same region (Tello Saenz et al., 2003. J. S. Am. Earth Sci. 15, 765-774) with 31 new samples analyzed. The weighted mean of the corrected ages from high Mantiqueira (around 1000m), (121+/-6)Ma, coincides with the South Atlantic opening. The fact that its thermal history starts at a relatively low temperature (∼80 deg. C) suggests that the age of ∼120Ma would be the formation age of Serra da Mantiqueira due to a rapid pulse, in which tracks had no time to be retained at the closure temperature, that is ∼120 deg. C. The Serra do Mar presents a more complicated thermal history, with several reactivations indicated by the changes in the slope of its cooling curve. The thermal histories obtained in the regions next to these mountain ranges are compatible with the results mentioned above. The Santos Basin has unconformities that agree with changes in the slope thermal histories of the studied region

    It is often argued that liquid biofuels are cleaner than fossil fuels, and therefore better for human health, however, the evidence on this issue is still unclear. Brazil's high uptake of ethanol and role as a major producer makes it the most appropriate case study to assess the merits of different biofuel policies. Accordingly, we modeled the impact on air quality and health of two future fuel scenarios in São Paulo State: a business-as-usual scenario where ethanol production and use proceeds according to government predictions and a counterfactual scenario where ethanol is frozen at 2010 levels and future transport fuel demand is met with gasoline. The population-weighted exposure to fine particulate matter (PM2.5) and ozone was 3.0 μg/m³ and 0.3 ppb lower, respectively, in 2020 in the scenario emphasizing gasoline compared with the business-as-usual (ethanol) scenario. The lower exposure to both pollutants in the gasoline scenario would result in the population living 1100 additional life-years in the first year, and if sustained, would increase to 40,000 life-years in year 20 and continue to rise. Without additional measures to limit emissions, increasing the use of ethanol in Brazil could lead to higher air pollution-related population health burdens when compared to policy that prioritizes gasoline.

  13. Description of six autochthonous cases of canine visceral leishmaniasis diagnosed in Pedregulho (São Paulo, Brazil

    Full Text Available Visceral leishmaniasis is an infectious disease of chronic, emerging and zoonotic nature that presents various degrees of severity. In Brazil, this illness is caused by Leishmania infantum (Leishmania chagasi, which is transmitted by the bite of the sand fly Lutzomyia longipalpis, and dogs are its main reservoir. Given the increasing spread of this disease across Brazil, the aim of this study was to report on six cases of canine visceral leishmaniasis, diagnosed in June 2013, in the city of Pedregulho, State of São Paulo, considered to be a non-endemic area and free of phlebotomine sand flies. The diagnosis was based on clinical signs of the patients and additional tests (serological and parasitological. It was concluded that the diagnosis of leishmaniasis is complex because the clinical signs are similar to other systemic diseases, thus justifying the importance of parasitological test of bone marrow, considered "gold standard", in the confirmation of the disease. In addition, the area was not, until now, considered risk place, despite notification.

    Full Text Available ABSTRACT: The aim of this study was to investigate the occurrence of Tritrichomonas foetus in cats in the area surrounding the city of Araçatuba municipality, State of São Paulo, Brazil. Fecal samples from 129 cats were collected by rectal flush technique. It was compared two diagnosis methods, direct examination of feces and PCR. The presence of T. foetus DNA was verified using PCR by amplification of 347-bp fragment from the primers TFR3 and TFR4 and amplicons of positive cases were sequenced. Statistical analyses were performed investigating the associations between T. foetus infection with gender, age, breed, presence of diarrhea and/or history of diarrhea, previous treatment, lifestyle, origin, environment, and co-infection. T. foetus was observed in one sample (n=129 by direct microscopic examination of feces while PCR was positive in five samples (3.9%. Giardia species and Cryptosporidium species co-infection was also observed. Statistical analyses showed no significant associations between T. foetus infection and all listed factors, although most positive cats were asymptomatic and lived in multi-cat household. The isolates of T. foetus showed 100% identical sequences with other T. foetus isolates from cats around the world. So, the occurrence of T. foetus was confirmed in cats in Araçatuba city (Brazil. This parasite must be considered as a differential diagnosis in cats with diarrhea and also in asymptomatic carriers as source of infection in multi-cat environments.

    Full Text Available Population density in cetaceans can be estimated through photo-identification, mark-recapture, land-based observations and visual estimative. We the aim to contribute with conservation strategies, we used line transects (distance method to estimate the population density of the river dolphin, S. guianensis, in the estuarine region of Cananéia, Southeastern Brazil. The study, developed from May 2003 until April 2004, during dry and rainy seasons and different times of the day, included a sampling area divided into three sectors according to their proximity to the open sea: Sector I (the closest to the open sea; Sector II (with a large flow of fresh water and a salient declivity; and Sector III (with a large flow of fresh water and non salient declivity. Onboard random sampling was carried out in all three sectors, and dolphins seen from the bow to 90° on both port and starboard sides, were registered along with their position and distance from the boat. The total density found was 12.41ind/km² (CV=25.53% with an average of 2.2 individuals per group for both periods of the day, morning and afternoon. Densities also varied between dry and rainy seasons, being lower in the first with 5.77ind/km² (CV=27.87% than in the second 20.28ind/km² (CV=31.95%, respectively. Regarding the three sectors, a non-causal heterogeneous distribution was found: Sector I was the most populated (D=33.10ind/km², CV=13.34%, followed by Sector II (D=7.8ind/km², CV=21.07% and Sector III (D=3.04ind/km², CV=34.04%. The aforementioned area, due to its proximity to the open sea, has the highest salinity level and therefore has the greatest chance of holding most of the marine fish schools which can be cornered by dolphins on high declivity areas during fishing activities. This suggests that food availability may be the most important factor on the river dolphin’s distribution in the estuary. Similar studies will contribute to a better understanding of these populations

    We explored the relationship between tree growth in two tropical species and local and large-scale climate variability in Southeastern Brazil. Tree ring width chronologies of Tectona grandis (teak) and Pinus caribaea (Caribbean pine) trees were compared with local (Water Requirement Satisfaction Index—WRSI, Standardized Precipitation Index—SPI, and Palmer Drought Severity Index—PDSI) and large-scale climate indices that analyze the equatorial pacific sea surface temperature (Trans-Niño Index-TNI and Niño-3.4-N3.4) and atmospheric circulation variations in the Southern Hemisphere (Antarctic Oscillation-AAO). Teak trees showed positive correlation with three indices in the current summer and fall. A significant correlation between WRSI index and Caribbean pine was observed in the dry season preceding tree ring formation. The influence of large-scale climate patterns was observed only for TNI and AAO, where there was a radial growth reduction in months preceding the growing season with positive values of the TNI in teak trees and radial growth increase (decrease) during December (March) to February (May) of the previous (current) growing season with positive phase of the AAO in teak (Caribbean pine) trees. The development of a new dendroclimatological study in Southeastern Brazil sheds light to local and large-scale climate influence on tree growth in recent decades, contributing in future climate change studies.

    2001-01-01

    The effects of ionizing radiation to the human beings are well known for high and intermediate doses. As far as low level) radiation doses are concerned, there is no consensus. In order to get a better understanding of such effects it is necessary to assess the low doses with better accuracy. In this work, it was made an estimate of the annual ambient dose equivalent (H * (10)) to which the people are exposed in the city of Sao Paulo. Until now there are no data about it available in the literature. For the purpose of this evaluation, a map with various routes covering the largest and more representative area of the city was designed. The choice of points for data collection was made taking into account mainly the occupancy of the region. A portable gamma spectrometry system was used. It furnishes the rate of H * (10) and the measured gamma spectrum (in the range from 50 to 1670 keV) in the place of interest. The measurements were performed in a short time interval, since the gamma radiation arrives from a great extent of soil. Each measurement was done 1 m above the soil during 300 s. The rates of H * (10) varied from 33.1 to 152.3 nSv.h -1 , net values, obtained after subtraction of the cosmic rays contribution. The standard deviation was 22 n Sv.h -1 for an average for the city of Sao Paulo of 96.1(24) nSv.h -1 . In addition, average values of H * (10) rates for the city Health Divisions were calculated. Those values are not statistically equivalent and the whole set of data could not be treated as one, as the statistical Student test indicated a non homogeneity of the group of data. Hence it is necessary the accomplishment of a more detailed survey in order to verify the origin of the discrepancy. The mean value of H * (10) rate obtained for the city of Sao Paulo as converted to effective dose. in order to be compared with other places results It could be noticed that the annual average of effective dose for the city of Sao Paulo, 0.522(13) mSv, is superior to

    Full Text Available OBJECTIVE: To propose a mathematical method for the estimation of the Basic Reproduction Number, R0, of urban yellow fever in a dengue-infested area. METHODS: The method is based on the assumption that, as the same vector (Aedes aegypti causes both infections, all the quantities related to the mosquito, estimated from the initial phase of dengue epidemic, could be applied to yellow fever dynamics. It is demonstrated that R0 for yellow fever is, on average, 43% lower than that for dengue. This difference is due to the longer dengue viremia and its shorter extrinsic incubation period. RESULTS: In this study the analysis was expanded to the epidemiological situation of dengue in São Paulo in the year 2001. The total number of dengue cases increased from 3,582 in 2000 to 51,348 in 2001. It was then calculated R0 for yellow fever for every city which have shown R0 of dengue greater than 1. It was also estimated the total number of unprotected people living in highly risky areas for urban yellow fever. CONCLUSIONS: Currently there is a great number of non-vaccinated people living in Aedes aegypti infested area in the state of São Paulo.

    Air pollution is a severe problem in major urban areas due to increasing numbers of vehicles, reduced road capacity and few investments in public transportation, especially in developing countries. Public transportation has a special role in avoiding congestion and consequent environmental and health impacts but is considered expensive. The objective of this paper was to analyze the benefits of the São Paulo subway in terms of the air pollution in the city through strikes events, analyzing both the health outcomes and the related economic burden. For the strike events, increases in air pollutant concentrations during the strike day was observed when compared to a similar day in terms of day of the week and meteorological conditions. Increases in mortality were also observed and the associated economic burden calculated. Despite the elevated construction and operation costs of the subway, when environment and social values are considered, cost-benefit analysis results would indicate a worthwhile investment. The consideration of these aspects is essential to sustainable transportation analyses, and in the case of the São Paulo subway, our analysis clearly demonstrated the important role of this system in the city's environmental, social and economic attributes.

    Grasiela de Oliveira Rodrigues Medeiros

    Full Text Available ABSTRACT: Soil is a natural resource that has been affected by human pressures beyond its renewal capacity. For this reason, large agricultural areas that were productive have been abandoned due to soil degradation, mainly caused by the erosion process. The objective of this study was to apply the Universal Soil Loss Equation to generate more recent estimates of soil loss rates for the state of São Paulo using a database with information from medium resolution (30 m. The results showed that many areas of the state have high (critical levels of soil degradation due to the predominance of consolidated human activities, especially in growing sugarcane and pasture use. The average estimated rate of soil loss is 30 Mg ha-1 yr-1 and 59 % of the area of the state (except for water bodies and urban areas had estimated rates above 12 Mg ha-1 yr-1, considered as the average tolerance limit in the literature. The average rates of soil loss in areas with annual agricultural crops, semi-perennial agricultural crops (sugarcane, and permanent agricultural crops were 118, 78, and 38 Mg ha-1 yr-1 respectively. The state of São Paulo requires attention to conservation of soil resources, since most soils led to estimates beyond the tolerance limit.

    Full Text Available INTRODUCTION: Following yellow fever virus (YFV isolation in monkeys from the São José do Rio Preto region and two fatal human autochthonous cases from the Ribeirão Preto region, State of São Paulo, Brazil, two expeditions for entomological research and eco-epidemiological evaluation were conducted. METHODS: A total of 577 samples from humans, 108 from monkeys and 3,049 mosquitoes were analyzed by one or more methods: virus isolation, ELISA-IgM, RT-PCR, histopathology and immunohistochemical. RESULTS: Of the 577 human samples, 531 were tested by ELISA-IgM, with 3 positives, and 235 were inoculated into mice and 199 in cell culture, resulting in one virus isolation. One sample was positive by histopathology and immunohistochemical. Using RT-PCR, 25 samples were processed with 4 positive reactions. A total of 108 specimens of monkeys were examined, 108 were inoculated into mice and 45 in cell culture. Four virus strains were isolated from Alouattacaraya. A total of 931 mosquitoes were captured in Sao Jose do Rio Preto and 2,118 in Ribeirão Preto and separated into batches. A single isolation of YFV was derived from a batch of 9 mosquitoes Psorophoraferox, collected in Urupês, Ribeirão Preto region. A serological survey was conducted with 128 samples from the municipalities of São Carlos, Rincão and Ribeirão Preto and 10 samples from contacts of patients from Ribeirão Preto. All samples were negative by ELISA-IgM for YFV. CONCLUSIONS: The results confirm the circulation of yellow fever, even though sporadic, in the Sao Paulo State and reinforce the importance of vaccination against yellow fever in areas considered at risk.

    The atmospheric aerosols sources have been identified in Sao Paulo since the 80´s with the use of receptor models. The Metropolitan Area of São Paulo (MASP) is a megacity with a population of 21 million, corresponding to more than 11% of the total population of Brazil. The first results for the identification of sources of particles were obtained with the application of Absolute Principal Component Analysis, Factor Analysis and Chemical Mass Balance. More recently the Positive Matrix Factorization has been used in combination with the other receptor models. With the improvement of the aerosol composition analytical determination (more elements and better resolution) the source identification has became more accurate. But, in spite of that, the main sources are the same for fine particles: vehicular emission, secondary formation and biomass burning. The large amount of biofuels used in the MASP makes this region an important example of the atmospheric chemistry of fossil fuel and biofuel emissions. The 7 million vehicles can run on gasohol, ethanol (95% ethanol + 5% gasoline) and biodiesel (mostly for trucks and buses). We have considered the Black Carbon as the tracer for diesel engines and biomass burning, being this last source associated not only with burning of sugar cane plantation and forest fires, but also with wood and charcoal used in restaurant and domestic cooking and residues burning. The responsibility of the vehicular emission to the fine particles has been maintained in approximately 50% of the mass. The soil resuspension was associated with 8% of the fine particles origin. We are presenting the data obtained from experiments performed from 1983 to 2014, not continuously and mainly performed in the winter time. It is a long period of data that is going to be considered. The previous results obtained with the application of PCA were compared to that obtained with PMF applied to the historical data collected at MASP, showing the evolution of the

    Full Text Available ABSTRACT: Since the first isolation of canine parvovirus type 2 (CPV-2 in late 70’s new virus types as CPV-2a and CPV-2b have been emerged and becoming prevalent in natural canine population and more recently, a third subtype was identified , CPV-2c. The main purpose of this study was to detect and characterize canine parvovirus currently present in Central-West region of São Paulo state, in Brazil. Fecal samples were collected of vaccinated and non-vaccinated dogs, clinically suspected of having CPV infection brought to the Infectious Diseases Service, Veterinary Hospital of FMVZ-UNESP. All samples (n=30 were screening for canine parvovirus through hemagglutination test and those resulting as positive (n=20 were submitted to PCR and the products were subsequently sequenced for subtype characterization. Results were tested for association with age, hematological values, viral hemagglutination titers in the feces, vaccination status and survival. Leukopenia was found in all animals, death occurred in 30% of unvaccinated dogs and in 42% of vaccinated ones. In a total of 20 positive sequenced samples, 18 were classified as CPV-2b, one as CPV-2c, and one as CPV-2a, being CPV2a and CPV2c detected in unvaccinated puppies. Compared to the reference samples amino acid change at position 426 in those circling virus was identified. The study results demonstrate the predominance of CPV-2b and the presence of CPV-2a and CPV-2c in naturally infected, vaccinated and unvaccinated dogs in in São Paulo region.

    Although urban horticulture provides multiple benefits to society, the extent to which these vegetables are contaminated by the absorption of chemical elements derived from atmospheric deposition is unclear. This study was designed to evaluate the influence of air pollution on leafy vegetables in community gardens of Sao Paulo, Brazil. Vegetable seedlings of Brassica oleracea var. acephala (collard greens) and Spinacia oleracea (spinach) obtained in a non-polluted rural area and growing in vessels containing standard uncontaminated soil were exposed for three consecutive periods of 30, 60 and 90 days in 10 community gardens in Sao Paulo and in one control site. The concentrations of 17 chemical elements (traffic-related elements and those essential to plant biology) were quantified by Inductively Coupled Plasma Mass Spectrometry (ICP-MS). Tillandsia usneoides L. specimens were used as air plant biomonitors. The concentrations of As, Cd, Cr and Pb found in vegetables were compared to the recommended values for consumption. Principal Component Analysis (PCA) was used to cluster the elemental concentrations, and Generalized Linear Models (GLMs) were employed to evaluate the association of the factor scores from each PCA component with variables such as local weather, traffic burden and vertical barriers adjacent to the gardens. We found significant differences in the elemental concentrations of the vegetables in the different community gardens. These differences were related to the overall traffic burden, vertical obstacles and local weather. The Pb and Cd concentrations in both vegetables exceeded the limit values for consumption after 60 days of exposure. A strong correlation was observed between the concentration of traffic-related elements in vegetables and in Tillandsia usneoides L. An exposure response was observed between traffic burden and traffic-derived particles absorbed in the vegetables. Traffic-derived air pollution directly influences the absorption of

    To describe obesity among students of public schools in São Paulo and to identify risk factors for this nutritional and physical activity disorder. Case-control study of obese and non-obese schoolchildren to study risk factors for obesity. Anthropometric survey including 2519 children attending eight elementary public schools in São Paulo, Brazil. Schoolchildren aged 7-10 years, of whom 223 were obese (cases; weight-for-height greater than or equal to two standard deviations (>or=2SD) above the median of the National Center for Health Statistics (NCHS) reference population) and 223 were eutrophic (controls; weight-for-height +/-1SD from NCHS median). Parents or guardians of the 446 cases and controls were interviewed about the children's eating behaviours and habits. The prevalence of obesity (weight-for-height >or=2SD) in the surveyed population was 10.5%. A logistic regression model fitted to the case-control dataset showed that obesity was positively associated with the following factors: birth weight >or=3500 g (odds ratio (OR) 1.83, 95% confidence interval (CI) 1.21-2.78), child's appetite at meals (OR 3.81, 95% CI 2.49-5.83), watching television for 4 h per day or longer (OR 2.07, 95% CI 1.32-3.24), mother's schooling >4 years (OR 1.85, 95% CI 1.25-2.75) and parents' body mass index >or=30 kg x m(-2) (OR 2.50, 95% CI 1.43-4.37). The explanatory multivariate model points to preventive measures that would encourage knowledge of the children and their guardians in relation to a balanced diet and a less sedentary lifestyle, such as reducing television viewing. Schoolchildren with a birth weight of 3500 g or more or whose parents are obese should receive special attention in the prevention of obesity.

    Environmental factors influence the coffee beverage quality and air temperature has a significant importance in this process. The grain maturation occurs very quickly in regions that present high temperatures and sometimes there is not enough time to complete all this phase adequately. In the other hand, with mild temperatures, the grain maturation occurs more slowly and it promotes a better quality beverage. The aim of this study was to assess the coffee beverage quality in the southeastern Brazil, based on climate projections using the Eta-CPTEC regional model driven by four members of an ensemble of the Met Office Hadley Centre Global Coupled climate model (HadCM3). The global model ensemble was run over the 21st century according to IPCC SRES, A1B emissions scenario. Each ensemble member presented different climate sensitivity in the analysis. The Eta-CPTEC-HadCM3 model was configured with a 40-km grid size and was run over the period of 1961-90 to represent a baseline climate, and over the period of 2011-2100 to simulate possible future changes and the effects on the coffee beverage quality. A coffee beverage quality classification, which depends on the annual air temperature proposed by Bressani (2007) and also, a quality coffee beverage sensory classification, based on Camargo and Cortez (1998) were considered in this study. An evaluation of the systematic errors (BIAS) for each member for the period from 1961 to 1990 was made. The results presented by Eta/CPTEC-HadCM3 model indicated that in the case of an occurrence of A1B emission scenario, the coffee beverage quality could be affected in this region due to the fact that the flavor may become stronger and unpleasant caused by rising air temperatures. The BIAS evaluation and subsequent errors removal demonstrated improvement in the scenarios simulations. A short review concerning agronomic techniques to mitigate extreme meteorological events or global warming on coffee crop based on Camargo (2010) also is

    Visceral leishmaniasis (VL), a neglected disease, is a serious public health problem that affects millions of people worldwide. The objectives of the study were to evaluate the sensitivity of Lutzomyia longipalpis and canine VL (CVL) autochthony early detection and describe the spatial and temporal dispersal of vector and expansion of VL in a Brazilian state. We obtained data on the leishmaniasis vector and VL cases in São Paulo State (SP), Brazil, from the Division of Endemic Disease Control and from the Epidemiological Surveillance Center of the São Paulo State Department of Health. Data were analyzed for 645 municipalities and 63 microregions and presented as thematic and flow maps. Following the verified presence of L. longipalpis in Araçatuba in 1997, the first autochthonous cases of canine VL (CVL) (1998) and of human VL (HVL) (1999) in São Paulo were reported, both in Araçatuba. From 1997 to 2014, the urban presence of the leishmaniasis vector was verified in 167 (25.9%) municipalities with cases of CVL reported in 108 (16.7%) and cases of HVL in 84 (13%). The sensitivities for vector presence early detection in relation to the identification of CVL and HVL autochthony were, respectively, equal to 76.4 and 92.5%. The sensitivity for CVL autochthony early detection in relation to the HVL autochthony identification was 75.8%. Vector dispersal and expansion of CVL and HVL were from the northwest to the southeast of the state, primarily flanking the Marechal Rondon highway at a constant rate of progression of 10, seven, and six new municipalities affected per year, respectively. We concluded that the sensitivity for vector presence and CVL autochthony presented reasonable accuracy and most of the time the vector presence and, specially, the CVL and HVL autochthony were identified in the main cities of the microregions of SP. Vector dispersal and expansion of VL started in 1997 near the state border of SP with the state of Mato Grosso do Sul. It has advanced

    To estimate transition probabilities between disability states, total life expectancy, and the latter's decomposition into years spent disabled and disability-free by age, sex, and education among older adults in São Paulo, Brazil, and urban areas in Mexico. Applied a micro-simulation method (Interpolative Markov Chains) using longitudinal data. We found large between-country educational differences in incidence of and recovery from disability with higher rates in Mexico than in São Paulo, but no differences in mortality. Older adults in Mexico spent longer time being disability-free than in São Paulo for both levels of education. Males and females in São Paulo spent a larger fraction of their remaining life disabled at every age than their counterparts in urban areas in Mexico. There were educational differences in the prevalence of disability in São Paulo and urban areas in Mexico, and significant educational differences in disability incidence and recovery across sites.

    Full Text Available ABSTRACT Compared to previous years, seasonal influenza activity commenced early in São Paulo State, Brazil, Southern hemisphere during the 2016 year. In order to investigate the genetic pattern of influenza A(H1N1pdm09 in the State of Sao Paulo a total of 479 respiratory samples, collected in January by Sentinel Surveillance Units, were screened by real-time RT-PCR. A total of 6 Influenza viruses A(H1N1pdm09 presenting ct values ≤ 30 were sequenced following phylogenetic analysis. The present study identified the circulation of the new 6B.1 subgroup (A/Sao Paulo/10-118/2016 and A/Sao Paulo/3032/2016. In addition, influenza A(H1N1pdm09 group 6B has also been identified during January in the State of Sao Paulo. Despite amino acid changes and changes in potential glycosylation motifs, 6B.1 viruses were well inhibited by the reference ferret antiserum against A/California/07/2009 virus, the A(H1N1pdm09 component of the vaccine for the 2016 influenza season.

    Describe cross-cultural differences in nutrition-related factors among adolescents from São Paulo, Brazil and St Paul-Minneapolis, US. Two large-population-based studies with cross-cultural comparisons. Twelve São Paulo and 10 St Paul-Minneapolis high schools in 2009-2010. A total of 1,148 adolescents from São Paulo and 1,632 adolescents from St Paul-Minneapolis. Meal consumption, family meals, fast-food consumption, and home food availability. Binomial regressions, weighted for age distributions and adjusted for gender, were used to compare identical measures from each sample. Generally, São Paulo adolescents reported healthier nutritional outcomes than St Paul-Minneapolis adolescents. São Paulo adolescents were 7 times less likely to report high fast-food consumption than St Paul-Minneapolis adolescents (P culture. Interventions are needed to encourage youth and their families to maintain these patterns. Copyright © 2014 Society for Nutrition Education and Behavior. Published by Elsevier Inc.

    Two serological surveys were carried out to evaluate the effectiveness of measures put into effect in the State of São Paulo (Brazil) to control Chagas disease vectors. The first one, during the period from 1968 to 1970; the complement fixation reaction was performed on serum samples from school-children resident in all municipalities of the State of São Paulo, with the exception of the Greater São Paulo. The second one, annually, from 1973 to 1983, involving school-children resident in municipalities with high trypanosomiasis prevalence values; the indirect immuno-fluorescence test was performed on filter paper total blood eluates. Data on the occurrence of triatomines and their infection with Trypanosoma cruzi in each municipality formed the basis of insight into the epidemiological situation associated with the school-children's dates of birth. Most positive serological results, as well as the highest proportion of autochthonous cases associated with Triatoma infestans were observed in the region of Sorocaba until the early 1970s, while the proportions of both autochthonous and imported cases were kept in equilibrium elsewhere. It has been inferred that as recently as 1974, vectorial transmission of Chagas disease could still be observed in the State of São Paulo. We emphasize that, even rather lacking in coverage, no seropositive cases have been observed in people inhabiting the regions included in the Control Program for the State of São Paulo and now aged less than 15 years.

In this contribution, a new genus and species of lizard, Brasiliguana prudentis gen. et sp. nov., is described based on an isolated left maxilla with teeth. The material was discovered in an outcrop of the Upper Cretaceous Adamantina Formation (Bauru Group located in the proximity of Presidente Prudente Municipality, São Paulo State, Brazil. The new taxon is considered a basal non-Priscagamidae+Acrodonta iguanian based on the presence of a weakly inclined anterior margin of the maxillary nasal process and maxillary tooth shape and tooth implantation similar to that of iguanians rather than of other lizard groups (e.g. teiids. This finding significantly increases the squamate lizard diversity of South America, which is still poorly understood and sparsely represented in the fossil record.Os achados de escamados (Reptilia, Squamata são escassos no Cretáceo do Brasil, incluindo cinco registros pontuais, dois do Aptiano-Albiano da Bacia do Araripe (Tijubina pontei Bonfim-Júnior e Marques e Olindalacerta brasiliensis Evans e Yabumoto, e três do Cretáceo Superior do Grupo Bauru (Pristiguana brasiliensis Estes and Price, Anilioidae gen. et sp. indet., Squamata gen. et sp. indet..

    Full Text Available The analysis of the influence of edaphic finer textures, as a facilitating factor for the expansion of forest formations in the absence of fire, was possible thanks to rare characteristics found in a savanna fragment located in the State of São Paulo, Brazil. The total suppression of fire for over four decades, and the occurrence of two savanna physiognomies, cerrado sensu stricto and cerradão, allowed the conduction of this study based on the hypothesis that cerradão, a physiognomy of forest aspect consisting of fire-sensitive tree and shrubs species, is favored by fire absence and higher soil hydric retention capacity. Edaphic samples were collected from a regular grid of 200 m² for the production of isopletic maps of the distribution of clay, fine sand, coarse sand and silt edaphic textures by the geostatistic method of ordinary kriging. Changes in the areas occupied by both savanna physiognomies, defined on the basis of aerial photographs taken over a period of 43 years, were assessed through mean variation rates. Besides corroborating the hypothesis of edaphic hydric retention as a facilitating factor for the expansion of forest physiognomies in savanna areas, we were able to infer the positive influence of higher precipitation on the increase in cerradão expansion rates.A influência de texturas edáficas finas, como fator de facilitação para a expansão de formações florestais sobre áreas savânicas, através da maior retenção hídrica edáfica, na ausência de incêndios, foi possível ser estudada graças às características encontradas em um fragmento savânico com 38,8 ha, situado em Corumbataí (SP.

    Primary production measurements were carried out at three reservoirs in the state of Sao Paulo, Barra Bonita, Paiva Castro and Ponte nova using the 14 C technique. Meanwhile, several physical and chemical parameters of these water were also evaluated, in order to find out the limnological conditions of these reservoirs. Primary production rates ranged from 7,6mg C/m 3 d at Ponte Nova, to 247,2mg C/m 3 d at Barra Bonita. There seems to be god correlation between water quality data and primary production measurements. Regarding the results, it may be stated that the Barra Bonita reservoir has reached the eutrophic level, while the other two exibit mesotrophic levels. As a way of testing the water quality data collected was used in Churchill and Nicholas model, issuing results in agreement with those of the primary production measurements. (Author) [pt

    An isotopic and hydrochemical study was performed in three aquifers in Rio Claro city area, Sao Paulo State, to establish the chemical facies of the groundwaters and to evaluate the mechanisms of dissolution of the unstable isotope 234 U and 238 U. Mapped groundwater facies were: calcium-bicarbonate for Rio Claro Formation, sodium-nitrate-chloride for fractures in database and sodium-bicarbonate for Tubarao Group. The highest dissolved U contents were measured in groundwaters from the fractured diabase, however, the groundwaters from Tubarao Group showed the highest base-exchange index. Most of the results showed enhancement of 234 U in solution and the highest 234 U/ 238 U activity ratios were measured for groundwaters from Tubarao Group. (author). 33 refs., 5 figs., 1 tab

    Leaching of 14 C-endosulfan insecticide was studied in soil columns for three soils of Sao Paulo State with different physical-chemical properties. A water flux of 0.41 ml/min., was established, simulating a pluviometric precipitation of 200 mm in 48 h. For all soils, an average of 78% of the total applied was retained in the first centimeters of the soil profile. As expected, the soil with the lowest soil organic matter and clay contents (sandy soil), was the soil with the largest amount of the insecticide leached. The higher the organic matter and the organic matter content of a soil, the higher its sorption and consequently there is less available in soil solution to be leached. In all soils, however, the amount of endosulfan found in the leachate was low, being 0.17% the maximum radioactivity measured. (author). 5 refs, 3 tabs

    New Rb-Sr whole rock isochron ages have been determined for the main lithological units that occur in Sao Paulo and Rio de Janeiro States. These rocks belong to Serra do Mar domain. The purpose of this work is to characterize the sequence of the geological events as well as the possible relationship between the different rocks. The geochronological data suggest that the paragneisses and the basement rocks, represented by ortho gneisses nuclei, were generated under amphibolite conditions around 700 Ma. At the same time the leucogranites were generated by partial melting processes and injected into both gneiss types. Tarditectonic granitic magmatic activities took place within ductile shear zones. One of the granites, the Getulandia granite, yielded an age of 514 Ma, falling in the range of the late Brasiliano Cycle which extended into the Middle Cambrian. (author). 9 figs., 1 tab

    Full Text Available Dogs sera samples collected from Cotia County, São Paulo were tested using indirect immunoenzymatic test (ELISA in order to study Lyme disease serology in dogs. ELISA method was standardized and G39/40 North American strain of Borrelia burgdorferi was used as antigen. Positive results were confirmed employing the Western blotting technique. Because of the possibility of cross-reactions, sera were also tested for different serological strains of Leptospira interrogans and L. biflexa using microscopic sera agglutination test. Twenty-three of 237 (9.7% serum samples were positive in the ELISA; 20 of them (86.9% were confirmed by the Western blotting, what suggests that Cotia may be a risk area for Lyme disease. Although 4 samples (1.7% were positive for Lyme disease and leptospirosis, no correlation was found between the results (X² = 0.725; p = 0.394 what suggests absence of serological cross reactivity.

Cyclospora cayetanensis has been identified in the feces of a patient by a modified Kinyoun staining method, with later sporulation in a solution of 2.5% potassium dichromate. The probability that this parasite is the eventual cause of gastrointestinal disturbances in the country was stimulated by this finding, which was arrived at by a simple technique. It had been kept in mind that the disease was expressing itself mainly among immunocompromised patients, whose number is increasing; especially in those with acquired immunodeficiency syndrome (AIDS, which is caused by the human immunodeficiency virus (HIV.É relatado o diagnóstico de ciclosporíase humana em São Paulo, SP, Brasil.

Esta verificação deve estimular a necessidade de considerar a ciclosporíase como eventual causa de distúrbios gastrointestinais no país, podendo ela ser reconhecida até mesmo por meio de técnica razoavelmente simples. Foi ainda lembrado que esta parasitose vem adquirindo expressividade sobretudo pelo fato de não raramente acometer imunodeprimidos, agora cada vez mais numerosos em especial como decorrência da infecção pelo vírus da imunodeficiência humana (HIV, que causa a síndrome da imunodeficiência adquirida (AIDS.

    São Paulo is one of the most populated cities in the world, with about 20 million inhabitants in its metropolitan area, more than 12 million motor vehicles and intense industrial activity. Given its importance as a major urban center in South America and the lack of information concerning urban dust composition, the present study aimed to determine rare earth elements (REEs), U and Th mass fractions in tunnel dust, collected in the Jânio Quadros Tunnel, and to assess their possible sources. The study of REEs distribution in urban environments has become of interest over the last decades, due to the increasing industrial use of these elements. The REEs, that are as common as the most familiar metals, are found in metallurgical additives, fluid cracking catalysts and automobile converter catalysts, among other applications. In this study, which employed Instrumental Neutron Activation Analysis (INAA) as analytical technique, the mass fractions of eight REEs were determined and normalized to the chondrite concentration values. The results showed that major concentrations were found for light REEs, following the sequence Ce > La > Nd > Sm > Yb > Eu > Tb > Lu. The pattern of the results pointed to a natural origin for these elements. Regarding U and Th concentrations, the results varied between 1.0 - 9.4 μg g{sup -1} and 3.3 - 35.9 μg g{sup -1}, respectively. Since there is almost no information about the concentration of these elements in this kind of matrix in São Paulo city, these data are important to support further investigations. (author)

    Full Text Available Although the causes of decline in bird populations in forest fragments are not well known, nest predation seems to play a major role in these events. A way to estimate the relative importance of predation for the reproduction of native birds is the use of artificial nests. Here, there is a report on the high rates of predation on artificial nests by two marmoset species from the genus Callithrix, C. pennicillata and C. jacchus, as well as their hybrid derivatives, in a Cerrado fragment in the state of Sao Paulo, Brazil. By means of artificial nests and quail eggs filled with paraffin, it was possible to identify the marmosets as predators through the bite pattern left on the paraffin. The results suggest a possible occurrence of predation on natural nests. Further studies involving the monitoring of natural nests will be able to confirm the role of marmosets in the decline of bird populations in the study area.

    The reproductive biology of Palythoa caribaeorum (Duchassaing & Michelotti 1860) and Protopalythoa variabilis (Duerden 1898) was studied through monthly samples from tagged colonies from June 1996 to June 1997, in Sao Sebastiao channel, São Paulo, Brazil (45 degrees 26'W, 23 degrees 50'S). The gametogenesis was similar to that of other zoanthids as shown by histological preparations. Oocyte diameters and maturation stages of testis vesicles were evaluated on squash preparations. Both species showed sequential protogynic hermaphroditism, with high frequency of fertile polyps (83% in P. variabilis and 72% in P. caribaeorun), high frequency of colonies in female sex condition (65.3% of P variabilis and 41.7% of P caribaeorum), and apparently continuous gametogenesis. In P. caribaribaeonrum, egg release was continuous and sperm release took place during half of the analyzed period. In P. variabilis, egg and sperm release occurred in April-May and February-March 1997, respectively.

    Full Text Available The paper reviews the taxonomic and ecological works on marine microalgae (phytoplankton and microphytobenthos off Paraná State, Southeastern Brazil. Various studies refer to the taxonomy of benthic diatoms. Few descriptive field works in coastal and adjacent shelf waters contribute to the understanding of phytoplankton dynamics in coastal and shelf areas. Patterns of geographic distribution and changes in the phytoplankton community are described in relation to water masses and seasonal variations in the hydrographic regime. During summertime, when warm oligotrophic waters predominate over the shelf, the phytoplankton is nummerically dominated by small phytotlagellates, dinotlagellates, coccolithophorids and filaments of cyanobacteria. During wintertime, the abundance of micro-size diatoms over the shclf increase due to the dominance of cold nutrient-rich waters from the South Atlantic Central Water and wind-driven vertical circulation. The phytoplankton community off Paraná State may be classified into two categorics: the diatom-dominated coastal assemblage, mainly controlled by nutrient inputs from land drainage and ressuspension of bottom sediments, and the tlagellate-dominated shelf assemblage, more affectcd by the seasonality of local hydrographic regime.O trabalho é uma revisão dos estudos taxonômicos e ecológicos das microalgas (planctônicas e bentônicas realizados no Estado do Paraná. A maioria dos trabalhos sobre microfitobentos são de caráter taxonômico e, basicamente, referem-se à diatomáceas bênticas sobre macroalgas ou fundos lodosos e consolidados. Poucos trabalhos contribuiram para o estudo da dinâmica espaço-temporal do fitoplâncton em áreas costeiras e de plataforma.

    The Brazilian Southeast was formerly occupied by Atlantic forest before the arrival of Europeans in the 16th century, when deforestation slowly started to take place. To understand the variations in the vegetation of Cabo Frio during the Quaternary, and possibly identify when they roughly took place, we make use of soil phytolith identification (as proxy), stable isotopes analyses and 14C dating of soil profiles. Nowadays, those are helpful tools to reveal the palaeoenvironmental secrets hidden below-ground. The soil profile studied, which was divided in 4 horizons ranging from 10 and 115 cm in depth, was collected in the surroundings of Cabo Frio, in the Rio de Janeiro (RJ), Southeastern coast of Brazil. Its total organic carbon (TOC) varied fr
