Positioning women's and children's health in African union policy-making: a policy analysis.
With limited time to achieve the Millennium Development Goals, progress towards improving women's and children's health needs to be accelerated. With Africa accounting for over half of the world's maternal and child deaths, the African Union (AU) has a critical role in prioritizing related policies and catalysing required investments and action. In this paper, the authors assess the evolution of African Union policies related to women's and children's health, and analyze how these policies are prioritized and framed. ⋯ We suggest that more effective prioritization of women's and children's health in African Union policies would be supported by widening the range of policy frames used (notably health and economic) and strengthening the evidence base of all policy frames used. In addition, we suggest it would be beneficial if the partner groups advocating for women's and children's health were multi-stakeholder, and included, for instance, health care professionals, regional institutions, parliamentarians, the media, academia, NGOs, development partners and the public and private sectors.

Bolus injection of hypertonic solutions for cerebral edema in rats: challenge of homeostasis of healthy brain.
Hypertonic solutions are mainstay of osmotherapy to cerebral edema. How hypertonic solutions affect healthy brain homeostasis, however, is not fully understood. Using rat model of cerebral edema induced by local cryoinjury, we found with immunohistochemistry that less microglial activation in healthy hemishere 24 h after hypertonic saline (HS, 3% NaCl) administration, compared to mannitol (20%, the same osmotic concentration of 3% NaCl) while dehydrating the brain tissue. ⋯ Meanwhile, HS injection led to AQP4 down regulation in expression similarly as mannitol, compared with NS group. These data suggested that bolus injection of hypertonic agents may lead to microglia activation in healthy brain in different extent, due to BBB compromise, instead of water movement or AQP4 expression. Hence in clinical application, BBB of healthy brain should be considered in perspective to maintain the brain homeostasis.
