OBJECTIVE: To describe HIV prevalence in pregnant women and the rate of vertical transmission according to socioeconomic status of residential neighborhoods. METHODS: Ecological exploratory study, which used the Information System of Notifiable Diseases database on HIV-positive pregnant women and AIDS in children, reported from 2000 to 2006, in Vitória, Southeastern Brazil. For analysis of socioeconomic data the Urban Quality Index was utilized The HIV prevalence rate in pregnant women and vertical transmission rate were calculated. Spatial distribution was carried out by Terraview 3.2.0. To verify the association between urban quality and HI V prevalence in pregnant women, Poisson regression was used. RESULTS: A total of 137 HIV-positive women and 14 children infected by vertical transmission was reported. Seven children matched to HIV-positive mothers without notification in the period analyzed. HIV prevalence among pregnant women in the period was 0.44%, and the vertical transmission rate was 9.7%. CONCLUSIONS: The prevalence of HIV infection among pregnant women and vertical transmission were associated with the urban quality of residential neighborhood. Neighborhoods with lower urban quality should be prioritized in actions to reduce vertical transmission.

Introduction: This systematic review of literature aims to verify prevalence rates of mental disorders in the Brazilian adult population. Methods: We searched the Medline and Lilacs in the period from 1997 to 2009 using the following descriptors: "mental disorders", "cross-section studies", "Brazil". Exclusion criteria of articles were: no abstract, no description of cross-sectional study, did not contain the estimate that would verify the prevalence of mental disorders, studies with specific populations and further studies with children, adolescents and elderly, and written in other languages other than Portuguese, English and Spanish. These criteria resulted in the selection of 25 articles. Results: In the studies reviewed found high rates of overall prevalence of mental disorders in adults. These rates varied between 20% and 56%, affecting mainly women and workers. Discussion: The studies analyzed in this review show an overview of mental disorders in Brazilian adult population, describing how is their distribution in this population, pointing to high rates, often associated with sex, age, socioeconomic, work conditions and lifestyles of individuals.

A remarkable hardening (∼30cm -1) of the normal mode of vibration associated with the symmetric stretching of the oxygen octahedra for the Ba 2FeReO 6 and Sr 2CrReO 6 double perovskites is observed below the corresponding magnetic ordering temperatures. The very large magnitude of this effect and its absence for the antisymmetric stretching mode provide evidence against a conventional spin-phonon coupling mechanism. Our observations are consistent with a collective excitation formed by the combination of the vibrational mode with oscillations of Fe or Cr 3d and Re 5d occupations and spin magnitudes. © 2012 American Physical Society.

Physiological quality and vigor of the seeds comprise properties that determine a high level of activity and performance during germination and seedling emergence, having a direct relation with the establishment of the stand of a crop. In this context, the assessment of seedling development, including the analysis of the seed reserves mobilization are a reliable method to investigate the physiological potential of seed lots. In this preliminary study, the aim was to investigate the dynamics of seed reserves mobilization of a sample of soybean commercial cultivars. By means of the seedling length bioassay and weight of dry matter of seeds, cotyledons, hypocotyls and radicles, information on the reserves mobilization during the germination process was obtained. Data were subjected to analysis of variance and Scott and Knott test, and afterwards, phenotypic correlations between traits were obtained. The results have shown that the dry matter of seeds, reserves reduction of seeds and dry matter of seedlings are positively correlated, and thus, seeds containing more reserves may be more effective during the early development of seedlings. In contrast, reserve reduction of seeds and conversion efficiency of the seeds reserves in the dry matter of seedlings are negatively correlated. © 2015 Associacao Brasileira de Tecnologia de Sementes.

Evaluation of the completeness of the System of Information on Mortality of suicide in the Southeast region, Brazil, from 1996 to 2007 [Avaliação da completude do Sistema de Informação sobre Mortalidade por suicídio na região Sudeste, Brasil, no período de 1996 a 2007]

Objective: Analyze the completeness of the data of SIM on the deaths of suicide in ES, Southeast and Brazil (1996 to 2007), referring to the demographic variables. Methods: A descriptive analytical study based on secondary data. The deaths registered in the SIM of suicide in Espírito Santo, Southeast and Brazil were included. The absolute number and percentage of non fulfillment of the variables in the declaration of death of suicide during the period was analyzed. To evaluate the degrees of non completeness of the socio demographic declaration of death variables, a score recommended by the researchers was adopted. The equations of the model chosen and the adjustment statistics for the missing data percentages over time (R2 value and p-value of the F test of model adequacy) were obtained from the SPSS program. The level of significance adopted was of 5%. Results: The equations of the models found show that the tendencies of non completeness for some variables are rising, while for other variables are falling and statistically significant. Conclusion: The sex and age variables indicated stability in the rates in ES, Southeast and Brazil, with significative improvements in the fulfillment of the declarations of death of the latter. As to the other variables, ES turned out to have the worst rates in the fulfillment of the declarations of death of suicide.
