High rate of viral identification and coinfections in infants with acute bronchiolitis
OBJECTIVES: To determine the viruses and risk factors associated with hospital and intensive care unit (ICU) admissions in infants with acute bronchiolitis. INTRODUCTION: Bronchiolitis is a major cause of morbidity in infants. Widespread use of molecular-based methods has yielded new insights about its etiology, but the impact of viral etiologies on early outcomes is still unclear. METHODS: Seventy-seven infants with bronchiolitis who were under two years of age and visited an emergency unit were included. Using molecular-based methods, samples were tested for 12 different respiratory viruses. Logistic regression models were used to identify clinical and virological variables associated with the main endpoints: hospital admission and ICU admission. RESULTS: We identified at least one virus in 93.5% of patients, and coinfections were found in nearly 40% of patients. RSV was the most common pathogen (63.6%), followed by rhinovirus (39%). Identification of RSV was only associated with an increased risk of hospital admission in the univariate model. Younger age and enterovirus infection were associated with an increased risk of hospital admission, while atopy of a first-degree relative showed a protective effect. Prematurity was associated with an increased risk of admission to the ICU. Coinfections were not associated with worse outcomes. CONCLUSIONS: Molecular-based methods resulted in high rates of viral identification but did not change the significant role of RSV in acute bronchiolitis. Younger age and enterovirus infection were risk factors for hospital admission, while prematurity appeared to be a significant risk factor for admission to the ICU in acute viral bronchiolitis.Sociedade Beneficiente Israelita Brasileira Hospital Israelita Albert Einstei

Diminuição da cobertura vacinal e aumento da incidência de Sarampo em um estado da Amazônia brasileira no período de 2016 a 2021: Decrease in vaccination coverage and increase in Measles incidence in a state of the brazilian Amazon from 2016 to 2021
O presente estudo tem por objetivo contribuir com a análise de dados epidemiológicos relacionados ao sarampo no Amapá. Trata-se de um estudo transversal, de caráter descritivo, abordagem quantitativa, abrangendo uma análise da cobertura vacinal para tríplice e tetra viral do estado amapaense. Após a análise dos dados, observou-se o aumento da incidência do sarampo, e a notificação de novos casos a partir de 2018 no estado do Amapá, com a maior concentração dos casos na faixa etária menor que 1 ano. Tais dados devem-se a diminuição da cobertura vacinal das vacinais Tríplice viral D1, D2, e Tetra viral, com isso nenhum município dessa unidade federativa alcançou a meta de cobertura vacinal estabelecida pelo Ministério da Saúde, de 95%, desde 2016. Dessa forma, a queda das coberturas vacinais teve impacto direto na reemergência do Sarampo, doença infectocontagiosa e imunoprevenível, que já estava erradicada desde 2016, devido a informações com baixa evidência cientifica, disseminadas a partir do movimento antivacina, e pela pandemia da covid-19, que foi um empecilho às novas medidas adotadas pelo Ministério da Saúde para aumento das coberturas vacinais
The contribution of the participatory guarantee system in the revival of agroecological principles in southern Minas Gerais, Brazil
Market pressures generated by the demand for organic food have pushed farmers to turn away from agroecological principles, which leads to actions focused directly on the agricultural practices for production. The objective of this study was to analyze whether the methodology used by the Participatory Guarantee Systems (PGS) contributes to farmers' appropriation of agroecological principles, understood here in their environmental, sociocultural, economic, and political dimensions. We analyzed the PGS-Sul de Minas, which was the first PGS founded in the state of Minas Gerais, Brazil and includes 14 organizations and more than 200 families. Documentary analysis and participant observation were prioritized in data collection. The main results are the correlation between the practices used by the farmers in these organizations with the principles of agroecology. This is evident in aspects such as the encouragement of productive diversification, the construction of new marketing alternatives, the revival and use of heirloom seeds, the stimulation of women's leadership, and places and policies that support and strengthen agroecology. The study found that the procedures adopted by the PGSs help strengthen agroecology and bring direct benefits to the farmers through revival and encouragement of agroecological principles1117COORDENAÇÃO DE APERFEIÇOAMENTO DE PESSOAL DE NÍVEL SUPERIOR - CAPESsem informaçã
Performance of seeder-fertilizer using two furrow opening mechanism and three loads on soil firming mechanism
O objetivo deste trabalho foi estudar o efeito de diferentes mecanismos rompedores e níveis de pressões aplicadas pela roda compactadora sobre o desempenho de uma semeadora-adubadora na implantação da cultura de soja, em plantio direto sob três teores de água no solo. O experimento foi montado em esquema de parcelas subsubdivididas, em que as parcelas foram constituídas pelos três teores avaliados de água no solo (0,22, 0,24 e 0,26 kg kg-1), as subparcelas por dois mecanismos rompedores (facão e disco duplo) e as subsubparcelas por três níveis de pressões aplicadas pela roda compactadora (12,2, 18,5 e 24,1 kPa), com três repetições, em um delineamento de blocos ao acaso. Foram analisadas a distância entre sementes, a profundidade de deposição, a porosidade, o índice de velocidade de emergência, a emergência a campo e a resistência do solo à penetração. O mecanismo rompedor do tipo facão proporciona maior profundidade de plantio e porosidade do solo, menor distância entre sementes e menor resistência do solo à penetração. A pressão da roda compactadora influencia a emergência de plântulas a campo, quando é usado o rompedor do tipo facão. O teor de água influencia a profundidade de deposição e distância entre sementes, o índice de velocidade de emergência e a resistência do solo à penetração.The objective of this work was to study the effect of different furrow opening mechanism and levels of load applied to soil firming mechanism on the initial development of soybean, in no-till system under different soil moisture. A split-split-plot experiment was used, in which the main treatments were three soil water contents (0.22, 0.24 e 0.26 kg kg-1), split-plots were two types of furrow opening mechanisms (furrow plough and double disk), and split-split-plots were three levels of load applied to soil firming mechanism (12.2, 18.5 and 24.1 kPa), using a randomized block design, with three replications. Distance between seeds, depth of seed allocation, soil porosity around the seed, emergence speed index, seedling emergence on field and soil resistance to penetration were analyzed. The furrow plough type of soil opening mechanism resulted in deeper seed allocation, higher soil porosity around the seed, smaller distance between seeds and smaller soil resistance to penetration. The pressure on the soil firming mechanism influences seedling emergence on field, when the furrow plough is used. The soil moisture influences the seed allocation and distance between seeds, the emergence speed index and the soil resistance to penetration
