Fundamento: O impacto press&#227;o arterial (PA) na adolesc&#234;ncia sobre outros fatores de risco cardiovascular em adultos jovens &#233; importante para a preven&#231;&#227;o prim&#225;ria. Objetivo: Avaliar a PA, &#237;ndices antropom&#233;tricos, perfil metab&#243;lico e inflamat&#243;rio de jovens estratificados pelo comportamento da sua PA obtida h&#225; 18 anos. M&#233;todos: Avaliaram-se 116 indiv&#237;duos, sendo 63 homes, pertencentes ao estudo do Rio de Janeiro (seguimento 17,76 &#177; 1,63 anos) em dois momentos: A1 (12,40 &#177; 1,49 anos) e A2 (30,09 &#177; 2,01 anos). Os 116 indiv&#237;duos foram divididos em dois grupos: GN (n = 71), PA normal em A1; e GH (n = 45): PA anormal em A1. A PA, o peso, a altura e o &#237;ndice de massa corporal (IMC) foram obtidos em A1 e A2. Em A2, acrescentaram-se a circunfer&#234;ncia abdominal (CA) e vari&#225;veis laboratoriais, metab&#243;licas e inflamat&#243;rias. Resultados: 1) Os grupos n&#227;o diferiram quanto &#224; idade e sexo; 2) Em A2, GH apresentou maiores m&#233;dias de peso, IMC, PA, insulina, HOMA-IR (p < 0,001), leptina (p < 0,02), Apolipoprote&#237;na B100 e A1 (p < 0,02), rela&#231;&#227;o Apolipoprote&#237;na B100 / Apolipoprote&#237;na A1 (p < 0,010), maiores preval&#234;ncias de sobrepeso/obesidade (p < 0,001), da CA aumentada (p < 0,001) e de hipertens&#227;o arterial (p < 0,02); 3) N&#227;o houve diferen&#231;a entre os grupos para as vari&#225;veis inflamat&#243;rias; 4) Houve correla&#231;&#227;o positiva da PA em A1 com a PA, o IMC, e com a insulina, a leptina e o HOMA-IR em A2 (p < 0,05). Conclus&#245;es: A PA na adolesc&#234;ncia se associou a maiores valores de PA, vari&#225;veis antropom&#233;tricas e metab&#243;licas na fase adulta jovem, mas n&#227;o a vari&#225;veis inflamat&#243;rias.

Evolution of Cardiovascular Diseases Mortality in the Counties of the State of Rio de Janeiro from 1979 to 2010

Background: Cardiovascular Diseases (CVD) are the leading cause of death in Brazil. Objective: To estimate total CVD, cerebrovascular disease (CBVD), and ischemic heart disease (IHD) mortality rates in adults in the counties of the state of Rio de Janeiro (SRJ), from 1979 to 2010. Methods: The counties of the SRJ were analysed according to their denominations stablished by the geopolitical structure of 1950, Each new county that have since been created, splitting from their original county, was grouped according to their former origin. Population Data were obtained from the Brazilian Institute of Geography and Statistics (IBGE), and data on deaths were obtained from DataSus/MS. Mean CVD, CBVD, and IHD mortality rates were estimated, compensated for deaths from ill-defined causes, and adjusted for age and sex using the direct method for three periods: 1979&#8211;1989, 1990&#8211;1999, and 2000&#8211;2010, Such results were spatially represented in maps. Tables were also constructed showing the mortality rates for each disease and year period. Results: There was a significant reduction in mortality rates across the three disease groups over the the three defined periods in all the county clusters analysed, Despite an initial mortality rate variation among the counties, it was observed a homogenization of such rates at the final period (2000&#8211;2010). The drop in CBVD mortality was greater than that in IHD mortality. Conclusion: Mortality due to CVD has steadily decreased in the SRJ in the last three decades. This reduction cannot be explained by greater access to high technology procedures or better control of cardiovascular risk factors as these facts have not occurred or happened in low proportion of cases with the exception of smoking which has decreased significantly. Therefore, it is necessary to seek explanations for this decrease, which may be related to improvements in the socioeconomic conditions of the population.

APOE and LDLR Gene Polymorphisms and Dyslipidemia Tracking. Rio de Janeiro Study

Background:Studies show an association between changes in apolipoprotein E (ApoE) and LDLR receptor with the occurrence of dyslipidemia.Objectives:To investigate the association between polymorphisms of the APOE (&#949;2, &#949;3, &#949;4) and LDLR (A370T) genes with the persistence of abnormal serum lipid levels in young individuals followed up for 17 years in the Rio de Janeiro Study.Methods:The study included 56 individuals (35 males) who underwent three assessments at different ages: A1 (mean age 13.30 �� 1.53 years), A2 (22.09 �� 1.91 years) and A3 (31.23 �� 1.99 years). Clinical evaluation with measurement of blood pressure (BP) and body mass index (BMI) was conducted at all three assessments. Measurement of waist circumference (WC) and serum lipids, and analysis of genetic polymorphisms by PCR-RFLP were performed at A2 and A3. Based on dyslipidemia tracking, three groups were established: 0 (no abnormal lipid value at A2 and A3), 1 (up to one abnormal lipid value at A2 or A3) and 2 (one or more abnormal lipid values at A2 and A3).Results:Compared with groups 0 and 1, group 2 presented higher mean values of BP, BMI, WC, LDL-c and TG (p < 0.01) and lower mean values of HDL-c (p = 0.001). Across the assessments, all individuals with APOE genotypes &#949;2/&#949;4 and &#949;4/&#949;4 maintained at least one abnormal lipid variable, whereas those with genotype &#949;2/&#949;3 did not show abnormal values (&#967;2 = 16.848, p = 0.032). For the LDLR genotypes, there was no significant difference among the groups.Conclusions:APOE gene polymorphisms were associated with dyslipidemia in young individuals followed up longitudinally from childhood.

Mortality from Circulatory System Diseases and Malformations in Children in the State of Rio de Janeiro

Abstract Background: The epidemiological profile of mortality in a population is important for the institution of measures to improve health care and reduce mortality Objective: To estimate mortality rates and the proportional mortality from cardiovascular diseases and malformations of the circulatory system in children and adolescents. Methods: This is a descriptive study of mortality from cardiovascular diseases, malformations of the circulatory system, from all causes, ill-defined causes and external causes in children and adolescents in the state of Rio de Janeiro from 1996 to 2012. Populations were obtained from the Brazilian Institute of Geography and Statistics (Instituto Brasileiro de Geografia e Estat��stica - IBGE) and deaths obtained from the Department of Informatics of the Unified Health System (DATASUS)/Ministry of Health. Results: There were 115,728 deaths from all causes, 69,757 in males. The annual mortality from cardiovascular diseases was 2.7/100,000 in men and 2.6/100,000 in women. The annual mortality from malformations of the circulatory system was 7.5/100,000 in men and 6.6/100,000 in women. Among the specific causes of circulatory diseases, cardiomyopathies had the highest rates of annual proportional mortality, and from malformations of the circulatory system, it occurred due to unspecified malformations of the circulatory system, at all ages and in both genders. Conclusion: Mortality from malformations of the circulatory system was most striking in the first years of life, while cardiovascular diseases were more relevant in adolescents. Low access to prenatal diagnosis or at birth probably prevented the proper treatment of malformations of the circulatory system.

Constata����o da mol��stia do ��anel vermelho�� do coqueiro no Estado do Rio de Janeiro. Redescri����o do agente causador - Aphelenchoides cocophilus (Cobb, 1919) Goodey, 1933 (Nematoda, aphelenchidae)

As it is generally said, the red ring disease of coconut palm (Cocos nucifera L.) is caused by a nematode which is regularly found in the diseased tissues. Such a nematode was described by COBB in 1919 as Aphelenchus cocophilus, having been placed by GOODEY, in 1933, in the genus Aphelenchoides. The species has been found occurring in three States of this country (Alagoas, Sergipe and Bahia). However, the Authors received from the Instituto de Ecologia e Experimenta����o Agr��colas, in Rio de Janeiro, a few samples of coconut tissues badly infested. So, its area of distribution is considerably enlarged. A. cocophilus is so slender and delicate a form that descriptions based on preserved material are frequentely inadequate. Thus, the Authors took this opportunity to re-examine and redescribe the species, as it was suggested by GOODEY (1923), what had not previously been made by those brazilian workers who have dealt with the disease. The population studied generally agreed with those examined by COBB (1919) and GOODEY (1923) in the details given, except in the dimensions mainly of the tail, as it is shown in table 1, where the measurements of 5 females and 5 males are presented.

Poliniza����o de Passiflora edulis f. flavicarpa (Passiflorales, Passifloraceae), por abelhas (Hymenoptera, Anthophoridae) em Campos dos Goytacazes, Rio de Janeiro

The yellow passion Passiflora edulis f. flavicarpa Deg. is allogamous, self incompatible, and it depends of insects pollinators to disseminate the pollen grains. The field work was conducted at Campos dos Goytacazes, Rio de Janeiro, Brazil, from October 17 to November 9 and December 12 to 21, 1995. It was analyzed 1565 flower buds, from which 423 showed well developed ovaries, five days after opening, this represents 27% of fruit set by natural pollination. It was observed 76,86 % of completely curved flowers, 21,22 % of partially curved flowers, and 1,92 % flowers without curvature. Five species of bees where observed on the flowers, from which two were the effective pollinator of yellow passion flower: Xylocopa (Megaxylocopa) frontalis (Olivier, 1789) and X. (Neoxylocopa) ordinaria Smith, 1874.

Ascidians (Urochordata: Ascidiacea) from Arraial do Cabo, Rio de Janeiro, Brazil

Simple and colonial ascidians were collected at different depths at Arraial do Cabo, Rio de Janeiro, between 2000 and 2003. The collection here presented includes representatives of the families Clavelinidae (Clavelina oblonga), Polycitoridae (Cystodytes dellechiajei), Polyclinidae (Polyclinum constellatum and Polyclinum molle sp. nov.), Holozoidae (Distaplia bermudensis), Ascidiidae (Ascidia sydneiensis and Phallusia nigra), Styelidae (Botrylloides giganteum, Botrylloides nigrum, Symplegma brakenhielmi, Symplegma rubra, Polyandrocarpa anguinea, Eusynstyela floridana, Eusynstyela tincta and Styela plicata), Pyuridae (Herdmania pallida and Microcosmus exasperatus). Didemnids were also collected in the area but were not considered here. Of the 17 species found, one (Polyclinum molle sp. nov.) is a new species in the family Polyclinidae and the others are all species with tropical distribution.

Water depth selection during foraging and efficiency in prey capture by the egrets Casmerodius albus and Egretta thula (Aves, Ardeidae) in an urban lagoon in Rio de Janeiro State, Brazil

This study aimed to evaluate the water depth selection during foraging, the efficiency in prey capture, and the food items captured by Casmerodius albus (Linnaeus, 1758) and Egretta thula (Molina, 1782). The work was conducted at an urban lagoon, Lagoa Rodrigo de Freitas, Rio de Janeiro. Four transects were made each month (two in the morning and two in the afternoon) for six months. When the birds were detected foraging, the water depth and the types of prey captured were recorded. There was no significant relationship between the foraging efficiencies of the two species. However, they differed in relation to the water depth when foraging, and also in the food items captured. Casmerodius albus captured mainly fishes while Egretta thula captured mainly invertebrates. The results suggest that the differences in water depth when foraging and the food items captured allow a differential use of the food resources available by C. albus and E. thula at Lagoa Rodrigo de Freitas.

Reproductive biology of the sesarmid crab Armases rubripes (Decapoda, Brachyura) from an estuarine area of the Sahy River, Sepetiba Bay, Rio de Janeiro, Brazil

The aim of this work was to gain knowledge about reproductive biology of the crab Armases rubripes (Rathbun, 1897) from an estuarine area of the Sepetiba Bay. Samples were taken monthly from February 2003 to January 2004 in the Sahy River estuary (22��56'S; 44��01'W), Rio de Janeiro, Brazil. The crabs were collected by hand during 15-minute catch-effort sessions conducted by two people. In the laboratory, the specimens were separated by sex, carapace width was measured and gonadal stage was checked macroscopically. A total of 830 individuals were caught - 304 males, 373 females (60 ovigerous females) and 153 juveniles. The ovigerous females were found almost year-round, except in November and April, showing a continuous reproductive period. They presented a size range from 8.2 to 15.0 mm carapace width (12.1 �� 1.7 mm). Color and macroscopical aspects determined five gonadal stages for males and females (immature, rudimentary, intermediary, developed and resting). First sexual maturity was estimated at 6.5 mm of carapace width for males and 8.1 mm for females. Individual fecundity varied from 200 to 11,460 eggs (4,458 �� 2,739 eggs). Mean egg size was 0.248 �� 0.026 mm, varying from 0.213 to 0.333 mm, while the volume ranged from 0.0051 to 0.0188 mm�� (0.0082 �� 0.0029 mm��).

Estrutura populacional dos camar��es simp��tricos Potimirim glabra e Potimirim potimirim (Crustacea, Decapoda, Atyidae) no rio Sahy, Rio de Janeiro, Brasil

Este trabalho teve por objetivo obter conhecimento sobre a estrutura populacional de dois camar��es de ��gua doce simp��tricos, Potimirim glabra (Kingsley, 1878) e Potimirim potimirim (M��ller, 1881) no rio Sahy, Mangaratiba, Rio de Janeiro, Brasil. Os indiv��duos foram coletados mensalmente durante o per��odo de setembro de 1997 a fevereiro de 1999 utilizando-se peneiras, que foram passadas sob a vegeta����o marginal, superf��cie de rochas e pequenas po��as d'��gua, num esfor��o de 15 minutos por coletor. Os animais foram separados quanto ao sexo e mensurados em rela����o ao comprimento total e do cefalot��rax. Um total de 4.889 indiv��duos foram coletados no rio Sahy: 3.281 P. glabra e 1.608 P. potimirim. A raz��o sexual observada foi de 1:1 para P. glabra e 1:2,3 para P. potimirim. Em ambas popula����es, cinco est��gios de maturidade sexual foram determinados, sendo as popula����es constitu��das principalmente por camar��es adultos. O recrutamento de juvenis apresentou diferen��as em ambas as esp��cies. O recrutamento de P. glabra ocorreu durante todo o per��odo de estudo, exceto na primavera, enquanto que P. potimirim foi registrado somente no outono. A distribui����o sazonal de f��meas ov��geras de P. glabra �� similar ao de P. potimirim, com reprodu����o na primavera e no ver��o.

Produtividade de peixes em um riacho costeiro da bacia do Leste, Rio de Janeiro, Brasil

As taxas de produ����o (P) e biomassa (B) de duas esp��cies de peixes de riacho foram estudadas em sete localidades da bacia de drenagem do rio Ubatiba, considerando-se dois ciclos anuais com ��ndices de pluviosidade contrastantes. Com o objetivo de testar correla����es potenciais entre P, B e o ��ndice de Heterogeneidade Ambiental (IHA) de cada localidade foram utilizadas correla����es simples, que n��o revelaram diferen��as significativas (p<0,01). O padr��o espacial de P indicou que as taxas de produ����o de ambas as esp��cies foram marcadamente homog��neas nas localidades de estudo, mas foram reduzidas quando comparadas com as esp��cies de peixes de riacho da regi��o Hol��rtica. Os valores m��dios de P e B de Astyanax hastatus Myers, 1928 foram: Pchuvoso = 14,0 kg.ha-1.ano-1, Pseco = 24,4 kg.ha-1.ano-1 e Bchuvoso = 7,3 kg.ha-1, Bseco = 12,2 kg.ha-1, com valores significativamente superiores durante o ano seco (t (B)= 2,41; p = 0,03 e t (P)= 2,28; p = 0,04). Apesar de ter apresentado tend��ncia semelhante �� registrada para A. hastatus, os valores de P e B de Geophagus brasiliensis (Quoy &amp; Gaimardi, 1824) n��o se mostraram significativamente diferentes (t (B) = 1,5; p = 0,16 e t (P) = 1,75; p = 0,11) entre os anos de estudo, sendo Pchuvoso = 25,2 kg.ha-1.ano-1, Pseco = 53,2 kg.ha-1.ano-1 e Bchuvoso = 16,6 kg.ha-1, Bseco = 29,7 kg.ha-1. As redu����es de P durante o ano de maior pluviosidade foram de 57% e 47% para A. hastatus e G. brasiliensis, respectivamente. Os valores m��dios da rela����o P/B mostraram tend��ncia a redu����o em rela����o ao aumento de tamanho dos indiv��duos de ambas as esp��cies.

Dados de reprodu����o de Platyrrhinus lineatus em estudo de longo prazo no Estado do Rio de Janeiro (Mammalia, Chiroptera, Phyllostomidae)

Baseado em uma grande amostragem de morcegos realizada na Mata Atl��ntica, Estado do Rio de Janeiro, sudeste do Brasil, n��s analisamos a biologia reprodutiva de Platyrrhinus lineatus (E. Geoffroy, 1810). Os morcegos foram capturados com redes de neblina entre 1989 e 2005, em 27 das 41 diferentes localidades amostradas. O come��o da ��poca reprodutiva foi estimado 30 dias antes da data da captura da primeira f��mea gr��vida. Para determina����o do t��rmino da ��poca reprodutiva empregamos a data da captura da ��ltima f��mea lactante mais 40 dias. O total de 688 morcegos adultos foi analisado, sendo 58,3% representados por f��meas. O maior n��mero de capturas foi observado nos meses de fevereiro, janeiro e agosto. Machos com test��culos escrotados foram observados em todos os meses. F��meas inativas sexualmente foram observadas com predomin��ncia em mar��o e de maio a agosto. F��meas com fetos palp��veis foram observadas em todos os meses, exceto em abril, junho e julho com pico em agosto-outubro e janeiro-fevereiro. F��meas lactantes foram capturadas de novembro a junho, com pico em novembro e fevereiro. F��meas simultaneamente gr��vidas e lactantes foram capturadas em todos os meses exceto em junho, com pico em abril. O tamanho da ��poca reprodutiva variou a cada ano, compreendendo de 8 a 12 meses, com m��dia de 10,6 meses.
