Cad. Saúde Colet., 2016, Rio de Janeiro, 24 (3): 376-383 376Hipertensão arterial e fatores associados em uma comunidade quilombola da Bahia, BrasilHypertension and associated factors in a community quilombola of Bahia, Brazil ResumoObjetivo: Determinar a prevalência da hipertensão arterial (HA) e investigar fatores associados em uma comunidade quilombola da Bahia, Brasil. Métodos: A HA foi determinada por autorreferimento de diagnóstico feito por um médico ou enfermeiro. Por meio de questionário, foram coletados dados demográficos, socioeconômicos, hábitos de vida e alimentares e presença de comorbidades. Foram realizadas medidas antropométricas e dosagens bioquímicas para determinação de sobrepeso/obesidade, diabetes e dislipidemias. Empregaram-se análise univariada para determinar associação entre HA e variáveis de interesse, e análise múltipla por regressão de Poisson para estimativa das razões de prevalência. Resultados: A população estudada foi de 213 indivíduos maiores de 18 anos. A prevalência de HA foi de 38,5%. Após análise ajustada, permaneceram associados à HA: sexo feminino, idade, menor escolaridade, maior renda per capita, uso de medicamentos nos últimos 15 dias, obesidade e diabetes mellitus. Conclusões: Os resultados evidenciam a necessidade de ações intersetoriais voltadas para a melhoria das condições de vida e saúde dessa comunidade. A adequação da infraestrutura e do funcionamento do serviço de saúde local, bem como a realização de campanhas de promoção da saúde, pode contribuir para a prevenção, diagnóstico precoce e tratamento da hipertensão e outros agravos. Palavras-chave: hipertensão; fatores de risco; comunidades vulneráveis; grupo com ancestrais do continente africano. AbstractObjective: To determine the prevalence of hypertension and investigate associated factors in a Quilombola community of Bahia (Brazil). Methods: Hypertension was based on diagnosis made by a physician or a nurse and self-reported by participants; demographic, socioeconomic, lifestyle, food habits, and comorbidities data were collected through a previously validated questionnaire. Anthropometric and biochemical measurements for overweight/obesity, diabetes and dyslipidemia were performed. Univariate and multivariable analysis using Poisson regression were conducted to estimate the association between hypertension and the variables of interest to estimate the adjusted prevalence ratios. Results: The study population comprised 213 individuals older than 18 years. The hypertension prevalence was 38.5%. In the adjusted analysis hypertension was associated with female sex, age, lower education, higher per capita income, use of drugs in the last 15 days, obesity, and diabetes mellitus. Conclusions: The results highlight the need for intersectorial actions to improve the community living conditions and health. The adequacy of local health service infrastructure and operation as well as health promotion campaigns can contribute to the prevention, early diagnosis and treatment of hypertension and other diseases.
Biofertilizers are sustainable alternatives to producers in order to reduce or replace the use of chemical fertilizers. Act directly or indirectly on all or parts of plants grown by providing nutrients and increasing its productivity. These formulations are comprised of easily accessible to the producer materials such as crop residues and use micro-organisms that act beneficially increasing the availability of nutrients to plants through biological processes. The Hortbio® is enriched aerobic bio-fertilizer developed by Embrapa Vegetables -DF. The aim of this study was to characterize the Hortbio® with regard to respect for their cultivable microbiota, indole acetic acid (IAA) concentration and biological contaminants, and to evaluate the effect of biofertilizer doses in different varieties of lettuce. Was used, for evaluation of microbiota, different biofertilizer production times, these being 0, 5, 10, 15, 20, 25 and 30 days of either preparation, they being Hortbio® 0 and 40 Hortbio® and inoculum EM (effective microorganisms). Was used culture media for the isolation of micro-organisms, these being R2A, Martin AC, and THSM MYGP for the isolation of total bacteria, total fungi, actinomycetes, Trichoderma spp. and yeast, respectively. The microorganisms were identified by DNA sequencing. For the determination of IAA concentration was used Hortbio® 0 in production times 10, 20 and 30 using the HPLC technique. For the valuation of biological contaminants, we evaluated the presence of Salmonella spp. and fecal coliforms in the product, as well as helminths and nematodes in five different biofertilizer. All those with 10 days of preparation. The effect of different doses of biofertilizer (0, 50, 100, 150, 200, 250 kg ha -1 N) of three types of lettuce (leaf, crisp head and cos lettuce) in a randomized trial conducted in pots. They evaluated different agronomic traits of lettuce, which are: the height (HP) and width of the plant (WP) of plants, fresh mass (FM), the average number of leaves (ANL) and the length (SL) and stem diameter (SD). Soil fertility was assessed by determining the Ca 2+ , Mg 2+ , K + , Na + , P, H+Al, cation exchange capacity (CEC), pH and soil organic matter (SOM). 217 microbial isolates were recovered, with 120 bacteria, 61 yeasts and 36 fungi. Among the found genera,
Cerrado is the second largest phytogeographic domain in Brazil, with a huge ethnobotany variety, including fruit species that stand out for their economic, industrial, biotechnological and medicinal potential. The objective of this study was to characterize the diversity of culturable yeasts and their potential for the production of hydrolytic enzymes in fruits of 13 species of native plants of the Cerrado in Brazil. Sequencing the 26S rRNA gene identified the isolates. The enzymatic potential was evaluated using specific substrates for the enzymes amylases, cellulases, proteases, and pectinases. Nine of the 13 fruit species analyzed showed yeast growth, totaling 82 isolates, identified in 26 species. The phylum Ascomycota predominated over Basidiomycota. The fruits of Butia capitata presented the highest species richness. Candida and Meyerozyma were the most frequent genera. About 57% of the isolates were able to produce at least one of the enzymes analyzed. The species Papiliotrema flavescens, Hanseniaspora meyeri, Meyerozyma guilliermondii, and Rhodotorula mucilaginosa produced all the enzymes tested. The results were found to expand the knowledge about the yeast communities present in fruits of the Cerrado native plants, evidencing the presence of species shared among the plants, and their potential for biotechnological use in the future.
In this study, we evaluated the occurrence and diversity of endophytic and total (endophytic + epiphytic) yeasts in fruits of seven Cerrado native plant species in two Conservation Units from the Distrito Federal, Brasília, Brazil. Healthy and mature fruits were collected for the isolation of yeasts using MYGP medium. After five days, the colonies were counted and the morphologically distinct yeasts were isolated axenic culture. The molecular identification of the isolates was performed using ITS region (rDNA). A total of 69 specimens of yeasts were isolated. The Guapira graciliflora (endophytic) and Ouratea hexasperma (total) hosts had higher yeast densities per gram of fruit and together with the Brosimum gaudichaudii showed higher species diversity. Yeasts belonging to the Ascomycota Phylum were predominant. The most frequent genera of yeasts were Candida, Aureobasidium and Hannaella. Others genera such as Hanseniaspora, Meyerozyma, Filobasidium, Cryptococcus, Symmetrospora, Sirobasidium, Meira, Rhodosporidiobolus, Papiliotrema and Erythrobasidium were identified. This is the first report of the occurrence of endophytic yeasts in fruits of G. graciliflora and represents the host with greater density and diversity of species of endophytic yeasts. In addition, expands the knowledge about the occurrence of yeasts associated with the fruits of seven native plant species of the Cerrado.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
