Geophagia, nutrition and health of women with pregnancy-induced hypertension.
Calcium is a major nutrient implicated in pregnancy-induced hypertension (PIH). Aside dietary sources, geophagia has been reported to provide calcium needed to prevent PIH. These soils are shown to contain significant amount of heavy metals which have been associated with hypertension. ⋯ In this study, geophagia during pregnancy is not directly associated with PIH but is detrimental to maternal health. The pregnant women in this study had considerably low intakes of energy and nutrients. There is a need for measures to ensure adequate maternal nutrition for a positive health and pregnancy outcomes.

Resistance development and insecticide susceptibility in Culex pipiens pipiens, an important vector of human diseases, against selection pressure of temephos and its relationship to cross-resistance towards organophosphates and pyrethroids insecticides.
Culex pipiens pipiens is an important vector of human diseases. ⋯ The high cross-resistance to temephos and chlorpyrifos is reasonable because they belong to the same class of insecticide (OP). However, the little cross-resistance to the pyrethroid permethrin could support its use alternately for Culex pipiens pipiens control.
