Pesquisa de Streptococcus Agalactiae na Secreção Vaginal e Anal de Gestantes de um Município do Noroeste Paulista

Streptococcus agalactiae has great medical importance in infections associated with severe neonatal morbidity and mortality. It is the most frequent bacterium isolated from the tables of septicemia, pneumonia and neonatal meningitis. This study aimed to determine the prevalence of anal and vaginal colonization of S. agalactiae in pregnant women at different gestational ages. We evaluated the incidence of colonization by S. agalactiae in 129 pregnant women of any age. Two samples of secretion were collected for culture: a perianal swab and a vaginal swab. Each of the two swabs were inoculated in test tubes containing Todd-Hewitt broth and subcultured on blood agar. After a period of 24 to 48 hours, the colonies suggestive of S. agalactiae were submitted to morfotintorial analysis and to biochemical tests for identification. Among 129 women studied, 3 (2.33%) have tested positive for Streptococcus agalactiae and 126 (97.67%) were negative. The results presented in this work are inferior to the data from other studies, however, the methodology used was compatible with most authors. Even so this rate is considered a relevant value taking into account the importance of Streptococcus agalactiae infections in pregnant women and newborns, emphasizing the importance of encouraging the culture of vaginal and anal secretion for the detection of Streptococcus agalactiae in surveys of prenatal care.O Streptococcus agalactiae tem grande importância médica nas infecções neonatais graves associadas com morbidade e mortalidade. É a bactéria mais frequentemente isolada dos quadros de septicemia, pneumonia e meningite neonatal. Este estudo teve como objetivo determinar a prevalência de colonização anal e vaginal de Streptococcus agalactiae em gestantes em diferentes idades gestacionais. A incidência de colonização por S. agalactiae foi avaliada em 129 gestantes de qualquer idade gestacional. Foram coletadas duas amostras de secreção para cultura: um swab perianal e um swab vaginal. Cada um dos dois swabs foi inoculado em tubo de ensaio contendo caldo de Todd-Hewitt e subcultivados em ágar sangue. Após 24 a 48 horas, as colônias sugestivas de Streptococcus agalactiae foram submetidas à análise morfotintorial e a provas bioquímicas para identificação. Das 129 gestantes analisadas, 3 (2,33%) tiverem cultura positiva para Streptococcus agalactiae e 126 (97,67%) apresentaram resultado negativo. Os resultados apresentados neste trabalho estão abaixo dos dados de outros estudos, entretanto, a metodologia utilizada foi compatível com a maioria dos autores. Ainda assim, essa taxa é considerada um valor relevante, tendo em vista a importância do Streptococcus agalactiae em infecções em gestantes e neonatos, ressaltando a necessidade de estimular a cultura de secreção vaginal e anal para pesquisa de Streptococcus agalactiae nos exames de pré-natal

Cardiovascular Statistics - Brazil 2021.

This is the 2021 edition of the Cardiovascular Statistics – Brazil , a multi-institutional effort to periodically provide updated information on the epidemiology of heart diseases and stroke in Brazil. The report incorporates official statistics provided by the Brazilian Ministry of Health and other government agencies, by the GBD project led by the IHME of the University of Washington, as well as data generated by other sources and scientific studies, such as cohorts and registries, on CVDs and their risk factors. The document is directed to researchers, clinicians, patients, healthcare policy makers, media professionals, the public, and others who seek comprehensive national data available on heart disease and stroke

Divergent biodiversity change within ecosystems

This project was funded by the European Research Council (AdG BioTIME 250189 and PoC BioCHANGE 727440). A.E.M. also acknowledges support from the Royal Society and M.D. from the Scottish Funding Council (Marine Alliance for Science and Technology for Scotland Grant HR09011).The Earth’s ecosystems are under unprecedented pressure, yet the nature of contemporary biodiversity change is not well understood. Growing evidence that community size is regulated highlights the need for improved understanding of community dynamics. As stability in community size could be underpinned by marked temporal turnover, a key question is the extent to which changes in both biodiversity dimensions (temporal α- and temporal β-diversity) covary within and among the assemblages that comprise natural communities. Here, we draw on a multiassemblage dataset (encompassing vertebrates, invertebrates, and unicellular plants) from a tropical freshwater ecosystem and employ a cyclic shift randomization to assess whether any directional change in temporal α-diversity and temporal β-diversity exceeds baseline levels. In the majority of cases, α-diversity remains stable over the 5-y time frame of our analysis, with little evidence for systematic change at the community level. In contrast, temporal β-diversity changes are more prevalent, and the two diversity dimensions are decoupled at both the within- and among-assemblage level. Consequently, a pressing research challenge is to establish how turnover supports regulation and when elevated temporal β-diversity jeopardizes community integrity.PostprintPostprintPeer reviewe

Orientação nutricional de crianças e adolescentes e os novos padrões de consumo: propagandas, embalagens e rótulos Nutritional guidance for children and adolescents and the new consumption patterns: advertising, packaging and labeling

OBJETIVO: Compilar e debater conhecimentos sobre os rótulos, as embalagens e a divulgação e promoção de alimentos processados que progressivamente passam a compor a dieta da população infanto-juvenil. FONTES DE DADOS: Artigos nos bancos de dados eletrônicos, Medline e SciELO nos últimos dez anos, nas línguas portuguesa e inglesa, utilizando os descritores "criança", "marketing", "hábitos alimentares", "televisão", "educação em Saúde".
