RESUMO

Abstract Quilombola communities are present in many Brazilian states living in precarious health conditions. This is due to geographic isolation, limitations to the access of the area in which they live in, and the lack of quality in the service when it is needed to be provided. Therefore, the aim of this study was to analyze the quality of life of women from a quilombola community in northeastern Brazil. It is an observational, cross-sectional and descriptive study. 160 adult women were first interviewed through a form to collect a profile and then it was applied the WHOQOL Quality of Life questionnaire - bref. It was observed that the women were on average 40.7 years old (±17.25), married, self-declared black, who did not finish elementary school, housewife, had no income, with their own masonry house, with up to 6 rooms, supplied by a box of community treated water. Quality of Life had median scores in the domains: physical (3.18), psychological (3.4), social relationships (3.45) and environment (2.59). With this research, it was possible to characterize the quilombola community of Santa Luzia do Norte-AL regarding the difficulties of access to health and income generation, issues that affect their health condition. The problems described in this study can contribute to health actions being planned and carried out in order to improve socioeconomic and health conditions in this community, considering the social, political and environmental context, valuing their traditional knowledge and practices.


Resumo As comunidades quilombolas, estão presentes em diversos estados brasileiros, vivendo em condições de saúde mais precárias. Isto ocorre por conta do isolamento geográfico, das limitações de acesso e da falta de qualidade no serviço quando este é prestado. Nesse sentido, o objetivo do estudo foi analisar a qualidade de vida de mulheres de uma comunidade quilombola do nordeste brasileiro. Estudo observacional, transversal e descritivo. Foram entrevistadas 160 mulheres adultas, através de um formulário para a coleta de perfil e do questionário de Qualidade de Vida WHOQOL - bref. Foi observado que as mulheres tinham em média 40,7 anos (±17,25), casadas, autodeclaradas negras, com fundamental incompleto, do lar, sem renda, com moradia de alvenaria, própria, com até 6 cômodos, abastecidas por caixa de água comunitária, tratada. A Qualidade de Vida, apresentou escores medianos nos domínios: físico (3,18), psicológico (3,4), relações sociais (3,45) e meio ambiente (2,59). Com a realização desta pesquisa foi possível caracterizar a comunidade quilombola de Santa Luzia do Norte-AL quanto as dificuldades de acesso a saúde e geração de renda, fatos que repercutem na sua condição de saúde. Os problemas descritos neste estudo podem contribuir para que ações de saúde sejam planejadas e efetivadas com o intuito de melhorar as condições socioeconômicas e de saúde nessa comunidade, considerando-se o contexto social, político e ambiental, valorizando seus saberes e práticas tradicionais.

RESUMO

Water is the indispensable natural resource for all living beings. For human consumption, it must be potable, so as not to pose a risk to health, and can be used for ingestion, food preparation and personal hygiene. Knowing this importance, this study aimed to carry out physical-chemical, microbiological and parasitological analyzes of water for human consumption in a quilombola community of Santa Luzia do Norte in Alagoas. A cross-sectional, experimental and quantitative study was carried out between January and December 2019. The physical-chemical parameters of residual chlorine, turbidity, fluoride, fluoridation, color and pH were analyzed, microbiological analyses were based on the research of total and thermotolerant coliforms (E. coli) and parasitological analyses were performed based on the research of protozoa and intestinal helminths. Some physical-chemical parameters (turbidity and pH) were observed outside the limits required by the Ministry of Health, and the presence of total coliforms in some of the analyzed samples (17.85%), characterizing this community at risk related to waterborne diseases. The samples analyzed did not present infecting forms of parasitic species. Regarding the variables evaluated, the results found showed that the lack of adequate basic sanitation affects the quality of water used for human consumption by the quilombola population of Santa Luzia do Norte-AL.

RESUMO

The susceptibility of 1st to 4th instars of Bemisia tabaci (Gennadius, 1989) (Hemiptera: Aleyrodidae) to three isolates of Cordyceps sp. (Hypocreales: Cordycipitaceae) was evaluated in screenhouse experiments under variable temperatures and moisture conditions. No differences in susceptibility to the Cordyceps sp. isolates were observed among 1st, 2nd, and 3rd instar nymphs with respect to median lethal time (LT50) values. Confirmed mortalities ranged from 63.7 to 87.8% when the isolates were tested at 5 × 107 conidia mL-1. The 4th instar was the least susceptible to the fungal isolates (≤ 36.6% mortality). However, 60.0 to 99.5% of the adults that emerged from 4th instar nymphs previously treated with the fungus succumbed to the infection. Temperature was more detrimental to Cordyceps sp. virulence towards B. tabaci nymphs than relative humidity (RH). At similar RH, median LT50 for 1st instar (9.4 days) was higher than for 3rd instar (5.3 days) when the fungus was tested at 5 × 107 conidia mL-1; minimal temperatures of ≥ 12.6°C compared to ≥ 17.0°C were registered for experiments with 1st and 3rd instars, respectively. However, temperatures ≥ 35°C for 4 to 6 h daily did not affect the efficacy of the fungus against nymphs. Cordyceps sp. showed high virulence to all life stages of B. tabaci at relatively low RH, and an ability to grow extensively over the leaf surface and to produce high amounts of conidia on infected hosts. These attributes certainly boost its potential as an important pest control component of B. tabaci biotype B, especially for management of populations resistant to synthetic insecticides.

RESUMO

In the present study, real car wash wastewater was purified by different coagulation/flocculation methods. As coagulant, polyaluminum chloride ('BOPAC'), conventional iron(III) chloride, iron(III) sulfate, and aluminum(III) chloride were used, while as flocculant non-ionic and anionic polyelectrolytes were investigated. The effects of added clay mineral (Na-bentonite) and cationic surfactant (hexadecyltrimethyl ammonium bromide - 'HTABr') were also investigated. The use of BOPAC was significantly more effective than conventional coagulants. Extra addition of clay mineral was also beneficial in relation to both the sediment volume and sedimentation speed, while polyelectrolyte addition enhanced further the sedimentation. Moreover, the simultaneous addition of HTABr significantly enhanced the color removal efficiency due to the successful in-situ generation of organophilic bentonite. In summary, the application of 100 mg L-1 Na-bentonite with 20 mg L-1 Al3+ (from BOPAC) and 0.5 mg L-1 anionic polyelectrolyte resulted in the efficient reduction of the turbidity (4-6 NTU), the COD (158 mg L-1) and the extractable oil content (4 mg L-1) with efficiencies of 98%, 59%, and 85%, respectively. By applying organophilic bentonite in high concentration (500 mg L-1) with identical concentrations of BOPAC and anionic polyelectrolyte, significant color removal (5 times lower absorbance at λ = 400 nm) and 27% lower sediment volume were achieved.

RESUMO

Vertebral osteomyelitis is an uncommon disease in children, presenting with signs and symptoms that, at least initially, make a correct diagnosis difficult to be achieved. The authors report five cases of vertebral osteomyelitis in children, describing its clinical and laboratory peculiarities. The usefulness of the different radiologic studies for the diagnosis and follow up of these patients is discussed. We confirm previous reports according to which, with adequate clinical and therapeutic management, the prognosis is good for most patients.
