Fasting blood glucose and 8-year mortality in the hypertension detection follow-up program population

This study analyzed the relationship between fasting blood glucose (FBG) and 8-year mortality in the Hypertension Detection Follow-up Program (HDFP) population. Fasting blood glucose (FBG) was examined both as a continuous variable and by specified FBG strata: Normal (FBG 60–100 mg/dL), Impaired (FBG ≥100 and ≤125 mg/dL), and Diabetic (FBG>125 mg/dL or pre-existing diabetes) subgroups. The relationship between type 2 diabetes was examined with all-cause mortality. This thesis described and compared the characteristics of fasting blood glucose strata by recognized glucose cut-points; described the mortality rates in the various fasting blood glucose strata using Kaplan-Meier mortality curves, and compared the mortality risk of various strata using Cox Regression analysis. Overall, mortality was significantly greater among Referred Care (RC) participants compared to Stepped Care (SC) {HR = 1.17; 95% CI (1.052,1.309); p-value = 0.004}, as reported by the HDFP investigators in 1979. Compared with SC participants, the RC mortality rate was significantly higher for the Normal FBG group {HR = 1.18; 95% CI (1.029,1.363); p-value = 0.019} and the Impaired FBG group, {HR = 1.34; 95% CI (1.036,1.734); p-value = 0.026,}. However, for the diabetic group, 8-year mortality did not differ significantly between the RC and SC groups after adjusting for race, gender, age, smoking status among Diabetic individuals {HR = 1.03; 95% CI (0.816,1.303); p-value = 0.798}. This latter finding is possibly due to a lack of a treatment difference of hypertension among Diabetic participants in both RC and SC groups. The largest difference in mortality between RC and SC was in the Impaired subgroup, suggesting that hypertensive patients with FBG between 100 and 125 mg/dL would benefit from aggressive antihypertensive therapy.^

Alfabetización semiótica en los umbrales. 16H246

Este proyecto problematiza los procesos de alfabetización en los umbrales escolares sobre la base de un enfoque semiótico a partir de conocimientos construidos en investigaciones anteriores. La profundización y sistematización de aspectos epistemológicos, teóricos y metodológicos apuntan a configurar un método de adquisición de la lengua escrita mediante el montaje/la instalación de atmósferas conversacionales en torno de protocolos de experiencias de la vida cotidiana. Considera la configuración pluriétnica y multilingüe de la jurisdicción de Misiones y las metas apuntan a resultados de interés teórico, metodológico y de incidencia en políticas públicas.

Significados e usos sociais da expertise na militancia ambientalista. En: Avá, nº 15.

Esse artigo examina os significados as lógicas sociais da utilizaçâo de recursos de expertise no ativismo ambientalista. Os procedimientos analíticos concentrarám-se numa história social do sector de protecâo ambiental e na investigaçâo da diversidade de esferas e de redes sociais articuladas ás trajetórias familiares, escolares, militantes e proffisionais dos militantes do Rio Grande do Sul. Os resultados obtidos demonstraram que os significados e a utilizaçâo da expertise no ativismo ambiental, estâo associados a padrôes distintos de reconversâo da formaçâo e do exercício profissional em diferentes esferas de actividade, com base nos vínculos anteriores e/ou simultâneos estabelecidos com redes diversificadas de organizaçôes e “movimentos sociais”.

Quaternary calcareous nannofossils from Periantarctic basins

Currently, coccolithophores have a widespread oceanic distribution and are reported from most latitudes, but not those higher than 65°S. Fifteen piston cores were sampled with the aim of investigating the distribution and abundance variation of Quaternary calcareous nannofossils of the Antarctic region, south of the Antarctic Divergence (>65°S), particularly from Maud Rise, Bausan Bank, and from Weddell, Ross and Bellingshausen Seas. A calcareous nannofossil cold-taxa association is present in most of the cores examined and their discontinuous occurrence is thought to indicate key environmental relationships. The presence of calcareous nannofossils is correlated with interglacial intervals with warmer SSTs and may indicate high productivity and an open-ocean environment. Our results confirm that, during short periods of the late Quaternary, coccolithophorids occurred at southern high latitudes, in the western Antarctic basins, while in the eastern Antarctic basins they are nearly absent, suggesting more variable SSTs near West Antarctic Ice Sheet.

El empobrecimiento de los suelos mendocinos cultivados con manzanos

En el presente trabajo se han estudiado las pérdidas edafológicas de nitrógeno, fósforo, y potasio del suelo mendocino cultivado con manzano (Malus sylvestris MILL.). Los autores llegan a la conclusión de que durante el trienio 1945 / 1948 se han perdido: 357,65 toneladas de N₂, 96,50 toneladas de P₂ O₅ y 525,88 toneladas de K₂ O. Asimismo consignan que para restituir dichas pérdidas se debería devolver a los suelos, en forma de fertilizantes: 1778 toneladas de sulfato de amonio 536 toneladas de superfosfato de calcio 1052 toneladas de sulfato de potasio
