“Background In a recent US cohort study total coffee and tea consumption was inversely associated with risk of glioma and ex penmental studies showed that caffeine can slow the invasive growth of glioblastoma
Objective The objective was to examine the relation between coffee
and tea Intake and the risk of glioma and meningioma in a large European cohort study the European Prospective Investigation into Cancer and Nutrition (EPIC)
Design Data on coffee and tea intake were collected from men and women recruited Into the EPIC cohort study Over an average of 8 5 y of follow up 343 cases of glioma and 245 cases of meningioma were selleck chemicals llc newly diagnosed in 9 countries We used Cox proportional hazards models to examine the relation between coffee and tea and brain tumors
Results We observed no associations between coffee tea or corn billed coffee and tea consumption and Selleck ATM Kinase Inhibitor risk of either type of brain tumor when using quantiles based on country-specific distributions of Intake However a significant inverse association was observed for glioma risk among those consuming >= 100 mL coffee and tea per
day compared with those consuming <100 mL/d (hazard ratio 0 66 95% CI 044 0 97 P = 0 03) The association was slightly stronger in men (hazard atm 059 95% CI 034 101) than in women (hazard ratio 0 71, 95% CI 042 131), although neither was statistically significant
Conclusions In this large cohort study we observed an inverse association between total coffee and tea consumption and risk of glioma that was consistent with the findings of a recent click here study These findings if further replicated in other studies may provide new avenues of research on gliomas Am J Clin Nutr 2010 92 1145-50″
“Background: The burden of malaria has decreased dramatically within the past several years in parts of sub-Saharan Africa. Further malaria control will require targeted control strategies based on evidence of risk. The objective of this study was to identify environmental risk factors for malaria transmission using remote sensing technologies to guide malaria control interventions in a region of declining burden of malaria.
Methods: Satellite images were used to construct a
sampling frame for the random selection of households enrolled in prospective longitudinal and cross-sectional surveys of malaria parasitaemia in Southern Province, Zambia. A digital elevation model (DEM) was derived from the Shuttle Radar Topography Mission version 3 DEM and used for landscape characterization, including landforms, elevation, aspect, slope, topographic wetness, topographic position index and hydrological models of stream networks.
Results: A total of 768 individuals from 128 randomly selected households were enrolled over 21 months, from the end of the rainy season in April 2007 through December 2008. Of the 768 individuals tested, 117 (15.2%) were positive by malaria rapid diagnostic test (RDT). Individuals residing within 3.
