SOJA, TAMBOS Y DESPOBLAMIENTO RURAL EN EL DPTO. CASTELLANOS. SANTA FE. ARGENTINA

En este trabajo se pretende analizar las características de la población rural, tanto dispersa como agrupada, del Departamento Castellanos, en función de cambios que se manifiestan en los últimos dos Censos Nacionales de Población y Vivienda (1991 y 2001) y relacionar estas características con las transformaciones que se produjeron en las tres últimas décadas en la estructura agropecuaria. Para ello se analizan fuentes oficiales de datos y entrevistas efectuadas a productores.El ritmo de crecimiento y la estructura de la población, como así también su distribución espacial, muestran signos evidentes de pérdida de poblacional.Esta zona integra la cuenca lechera santafesina-cordobesa, que se fue gestando desde principios del siglo veinte en base a explotaciones familiares medianas y pequeñas, que organizaron también la industria láctea gracias a un fuerte movimiento cooperativista. Alrededor de 1970 comienza en la región pampeana un fuerte proceso de avance del cultivo de soja que va desplazando a otros granos y a la ganadería. El desequilibrio entre la rentabilidad de la producción agrícola y la ganadera también tienen un alto impacto en la población rural: el abandono de explotaciones ganaderas, tanto de las destinadas a la producción de carne como lechera, provoca la expulsión de una enorme masa de trabajadores rurales y de mano de obra de industrias derivadas, sobre todo de las pequeñas medianas, provocando el despoblamiento del campo y de pequeñas localidades, como así también en un incremento de  la desocupación.

DINÁMICAS SOCIO DEMOGRÁFICAS EN EL MUNDO RURAL DE LA ARAUCANÍA

La Araucanìa es una de las regiones de Chile mayor ruralidad y de concentración de población indígena a nivel nacional. Actualmente se están manifestando de manera desigual en el territorio importantes procesos sociodemográficos, los que han ido transformando la estructura poblacional. De allí que el trabajo tiene como objetivo general, analizar las transformaciones sociodemográficas en la región de La Araucanìa entre 1992 y 2002. Metodológicamente se trabajó con información secundaria de los censos de población y vivienda de los años 1992-2002, considerando las variables de sexo y edad, población económicamente activa por sexo, nivel de educación de los jefes de hogar y tasa de dependencia. Los principales resultados señalan que la población rural ha disminuido, en especial la población joven, proceso que se da en gran parte de las unidades territoriales, con excepción de las áreas cercanas a la capital regional y zonas turísticas. También se asiste a un acelerado proceso de envejecimiento de la población, mayoritariamente con baja tasa de escolaridad y un aumento en la tasa de dependencia económica. La población dedicada a las labores agrícolas ha ido disminuyendo. Estos procesos se manifiestan heterogéneamente en el territorio.

[health Protection For Rural Workers: The Need To Standardize Techniques For Quantifying Dermal Exposure To Pesticides].

Quantification of dermal exposure to pesticides in rural workers, used in risk assessment, can be performed with different techniques such as patches or whole body evaluation. However, the wide variety of methods can jeopardize the process by producing disparate results, depending on the principles in sample collection. A critical review was thus performed on the main techniques for quantifying dermal exposure, calling attention to this issue and the need to establish a single methodology for quantification of dermal exposure in rural workers. Such harmonization of different techniques should help achieve safer and healthier working conditions. Techniques that can provide reliable exposure data are an essential first step towards avoiding harm to workers' health.

Análise das diferentes manifestações de cultura quanto aos cuidados em saúde bucal em moradores de região rural ribeirinha em Rondônia, Brasil

Esse estudo avaliou as práticas populares nos cuidados com a saúde bucal decorrentes de patologias como a cárie dentária, doença periodontal, entre outras, no distrito de Tabajara, Estado de Rondônia, Brasil, tendo em vista que o folclore é muito presente na cultura popular, sendo considerado um fato social e cultural, ao mesmo tempo atingindo e influenciando os cuidados quanto à saúde bucal. Realizou-se um estudo quanti-qualitativo, sendo a amostra composta por catorze mulheres e seis homens. O instrumento de pesquisa compreendeu um questionário, com questões objetivas e subjetivas, sendo os dados analisados sob a forma descritiva. Observou-se um baixo nível de conhecimento em aspectos relacionados à saúde bucal nas pessoas analisadas, bem como uma variedade de métodos alternativos para "tratamento" e "prevenção" de afecções bucais. Concluiu-se que há necessidade de um conhecimento mais aprofundado da população-alvo dos programas em saúde, haja vista que introduzem, quase sempre, mudanças culturais, e para que sejam construtivos e não desintegradores, devem levar em conta a estrutura sociocultural da comunidade onde serão executados.

Thermal performance of sisal fiber-cement roofing tiles for rural constructions

Roofing provides the main protection against direct solar radiation in animal housing. Appropriate thermal properties of roofing materials tend to improve the thermal comfort in the inner ambient. Nonasbestos fiber-cement roofing components reinforced with cellulose pulp from sisal (Agave sisalana) were produced by slurry and dewatering techniques, with an optional addition of polypropylene fibers. Nonasbestos tiles were evaluated and compared with commercially available asbestos-cement sheets and ceramic tiles (frequently chosen as roofing materials for animal housing). Thermal conductivity and thermal diffusivity of tiles were determined by the parallel hot-wire method, along with the evaluation of the downside surface temperature. Cement-based components reinforced with sisal pulp presented better thermal performance at room temperature (25ºC), while those reinforced with sisal pulp added by polypropylene fibers presented better thermal performance at 60ºC. Non-asbestos cement tiles provided more efficient protection against radiation than asbestos corrugated sheets.

Occurrence and molecular characterization of Cryptosporidium spp. isolated from domestic animals in a rural area surrounding Atlantic dry forest fragments in Teodoro Sampaio municipality, State of São Paulo, Brazil

The aim of this study was to assess the occurrence of Cryptosporidium in domestic animals in rural properties surrounding rain forest fragments within the municipality of Teodoro Sampaio, southeastern Brazil. Conventional sucrose flotation method followed by molecular characterization of the parasites by sequencing PCR products amplified from SSU rRNA gene were used. Stool samples were collected from domestic animals raised as pets and livestock in all rural properties surrounding three forest fragments. Samples from cattle (197), equine (63), pigs (25), sheep (11), and dogs (28) were collected from 98 rural properties. The frequency of occurrence of Cryptosporidium within each animal species was 3.0% (6/197) among cattle and 10.7% (3/28) among dogs. Cryptosporidium was not detected in stool samples from equine, sheep, and pigs. All sequences obtained from the six samples of calves showed molecular identity with Cryptosporidium andersoni while all sequences from dog samples were similar to C. canis. The frequency of occurrence of Cryptosporidium in these domestic animal species was low. The absence of C. parvum in the present study suggests that the zoonotic cycle of cryptosporidiosis may not be relevant in the region studied. The presence of Cryptosporidium species seldom described in humans may be, otherwise, important for the wild fauna as these animals are a source of infection and dissemination of this protozoan to other animal species. The impact and magnitude of infection by C. andersoni in wild ruminants and C. canis in wild canids have to be assessed in future studies to better understand the actual importance of these species in this region.

The present study showed for the first time the frequency of exposure to Leishmania spp. in dogs in the State of Rondônia, Amazon Region.

Prevalence of diabetes mellitus and impaired glucose tolerance in a rural community of Angola

Background: To determine the prevalence of diabetes mellitus (DM) and impaired glucose tolerance (IGT) in a rural community (Bengo) of Angola. Methods: A random sample of 421 subjects aged 30 to 69 years (30% men and 70% women) was selected from three villages of Bengo province. This cross-sectional home survey was conducted using a sampling design of stage conglomerates. First, clinical and anthropometric data were obtained and fasting capillary glucose level was determined. Subjects who screened positive (fasting capillary glucose >= 100 mg/dl and < 200 mg/dl) and each sixth consecutive subject who screened negative (fasting capillary glucose < 100 mg/dl) were submitted to the second phase of survey, consisting of the 75 g oral glucose tolerance test. Data was analyzed by the use of SAS statistical software. Results: The prevalence rates of diabetes mellitus and IGT were 2.8% and 8.1%, respectively. The age group with the highest prevalence of diabetes was 60 to 69 years (42%). Impaired glucose tolerance prevalence was 38% in the 40 to 49 year age group and it increased with age, considering that the 50 to 59 and 60 to 69 year age groups as a whole represent 50% of all subjects with impaired glucose tolerance. The prevalence of diabetes mellitus did not differ significantly between men (3.2%) and women (2.7%) (p = 0.47). On the other hand, the prevalence of impaired glucose tolerance among women showed almost twice that found in men (9.1% vs. 5.6%, respectively). Overweight was present in 66.7% of the individuals with diabetes mellitus and 26.5% of individuals with impaired glucose tolerance showed overweight or obesity. Conclusions: Although the prevalence of diabetes mellitus was low, the prevalence of impaired glucose tolerance is considered to be within an intermediary range, suggesting a future increase in the frequency of diabetes in this population.

Assessment of Depressive Symptoms and Cognitive Impairment in Elders From Rural Areas of the Brazilian State of Rio Grande do Sul

The main objective of this study was to examine the relationships among demographic characteristics, depressive symptoms, and cognitive impairment in oldest-old elders from rural areas of the Brazilian State of Rio Grande do Sul. A cross-sectional, descriptive correlational design was used to conduct the study. 137 Brazilian elders age 80 years or over. A target population data form, a county data form, a demographic questionnaire, the Mini-Mental State Examination, and the Depressive Cognition Scale were used to collect the data. A significant difference was found between males and females in regard to cognitive impairment. In addition, educational level and depressive symptoms were correlated with cognitive impairment. Depressive symptoms were a weak but significant predictor of cognitive impairment after controlling for the effect of age, gender, and educational level of the oldest-old elders. The findings need to be interpreted cautiously since the sample scored above the cutoff points for cognitive impairment, and had low scores on depressive symptoms. Despite several limitations, findings from this study can be a foundation for further studies, and well-designed correlational or experimental approaches, are warranted.
