Reseña

Background: Several studies have linked dietary intake and asthma symptoms, nevertheless the results are still inconclusive and data from developing country are scarce.

Objective: To assess the association of Food patterns and current asthma symptoms in school-aged children from rural and urban areas of Oropeza Province – Bolivia.

Methods: A total of 1655 children attending the fi fth elementary grade were invited to participate in a cross-sectional study in rural and urban areas of Oropeza province. Current Asthma symptoms were defi ned following the International Study of Asthma and Allergies in Childhood (ISSAC) recommendation (written and video questionnaire). Food patterns were defi ned using the ISAAC environmental questionnaire. The Mediterranean diet (MD) score was calculated based on this information. Crude and adjusted logistic regression models were calculated including age, sex and place of living.

Results: The age range was between 9 – 15 years (Median 11), and 47.9% were male. Current asthma symptoms were reported in a 17% considering the written questionnaire (WQ) and in a 6% considering the video questionnaire (VQ). Higher consumption of nuts [(p=0.01, aOR= 1.6(1.1-2.2)], corn [(p=0.03, aOR= 1.5(1.0-2.2)] and fast food [(p=0.06, aOR= 1.4(1.0-2.0)] showed positive association with current asthma symptoms. Greater adherence to the MD was associated with lower risk of asthma symptoms.

Conclusion: Promotion of healthy food patterns in children is needed in order to avoid the rapid increase of non-communicable diseases in this region.

Reseña

Objetivo: Comparar las dimensiones de riesgo psicosocial en profesores de áreas urbanas y rurales de Chuquisaca, Bolivia. Método: Se realizó un estudio transversal en 60 escuelas seleccionadas al azar (27 urbanos, 33 rurales) de Chuquisaca, invitando a participar a 1.062 profesores (Respuesta 58%). Se utilizó la versión breve del cuestionario SUSESO-ISTAS21 para medir riesgos psicosociales, calculando odds ratios y su Intervalo de Confianza de 95% a través de modelos de regresión logística ajustados por edad, sexo, grado académico más alto e ingresos.

Resultados: Los profesores de áreas rurales presentaron porcentajes más alto de riesgo psicosocial en comparación con los del área urbana, principalmente en las dimensiones: exigencias psicológicas (ORa 1,6; IC 95% 1,1-2,5), apoyo social y calidad del liderazgo (2,9; 1,9-4,8) y doble presencia (2,2; 1,5-3,4). Conclusiones: Se encontraron diferencias en riesgos psicosociales, de manera desfavorable en profesores de áreas rurales, lo que podría repercutir en la salud física y mental.

Reseña

Abstract The pronotum is the most distinctive and representative structure in treehoppers. Although several functions have been proposed for this structure, its involvement in fitness has not been formally evaluated. Given the high degree of maternal investment exhibited by the subsocial membracid Alchisme grossa (Hoplophorionini), the pronotum has been suggested as a shield for offspring protection. We performed selection gradient analyses on A. grossa in order to evaluate how natural selection is acting upon two traits associated with this structure considering three different fitness proxies: (1) number of eggs, (2) the ratio between the number of firststage nymphs and the number of eggs (early survival), and (3) the number of third-stage nymphs (late survival). Since A. grossa feeds, oviposits and mates on two alternative host-plants (Brugmansia suaveolens and Solanum ursinum, both Solanaceae), we also evaluated and compared selection gradients between these host-plants. We found positive

Reseña

Treehoppers (Hemiptera: Membracidae) are sap-feeding insects distributed mainly in tropical regions.Alchisme grossais a treehopper that has been reported in the Bolivian Yungas forests using mostlyBrugmansia suaveolens(Solanaceae) as host-plant, where adult females oviposit and take care of their nymphs until they molt to adults. Brugmansiais a subtropical genus producing a variety of tropane alkaloids (TAs). We herein report the sequestration by adult males and females of A. grossa of TAs from B. suaveolens, examining separately the distinct body sections of insects. Puried extracts of A. grossa and B. sua- veolenswere analyzed by gas chromatography/mass spectrometry. TAs in A. grossa were the same as those in its host-plant; furthermore, they were equally distributed between sexes and they were differentially allocated within the body of adult individuals. An ecological role for sequestered TAs is discussed.
