<p>In this letter we defend our stance that the Helen Keller Food Frequency Method of assessing community vitamin A status underestimates vitamin A status when breastfeeding is prolonged--as it is in South Asia where a substantial proportion of the world's severe vitamin A deficiency is located. </p
Information and socioeconomic factors associated with early breastfeeding practices in rural and urban Morogoro
No full text<p>Shirima R, Gebre-Medhin M and Greiner T. Information and socioeconomic factors associated with early breastfeeding practices in rural and urban Morogoro, Tanzania. Acta Paediatrica 90:936-942, 2001.</p>
<p>Exclusive breastfeeding is a traditional behavior (the norm within living memory) virtually nowhere. In this sample of women from both an urban and a rural area of Tanzania, this was reflected in the fact that the only factor correlated with the duration of exclusive breastfeeding was knowledge about it. </p
Exclusive breastfeeding is rarely practiced in rural and urban Morogoro, Tanzania
No full text<p>Shirima R, Greiner T, Kylberg E, and Gebre-Medhin M. Exclusive breastfeeding is rarely practiced in rural and urban Morogoro, Tanzania. Public Health Nutrition 4(2):147-154, 2001.</p>
<p>Early infant feeding practices were found to be better in the urban than in the near by rural sample but few mothers exclusively breast fed in either. </p

Heterogeneous and tissue-specific regulation of effector T cell responses by IFN-gamma during Plasmodium berghei ANKA infection.
No full textIFN-γ and T cells are both required for the development of experimental cerebral malaria during Plasmodium berghei ANKA infection. Surprisingly, however, the role of IFN-γ in shaping the effector CD4(+) and CD8(+) T cell response during this infection has not been examined in detail. To address this, we have compared the effector T cell responses in wild-type and IFN-γ(-/-) mice during P. berghei ANKA infection. The expansion of splenic CD4(+) and CD8(+) T cells during P. berghei ANKA infection was unaffected by the absence of IFN-γ, but the contraction phase of the T cell response was significantly attenuated. Splenic T cell activation and effector function were essentially normal in IFN-γ(-/-) mice; however, the migration to, and accumulation of, effector CD4(+) and CD8(+) T cells in the lung, liver, and brain was altered in IFN-γ(-/-) mice. Interestingly, activation and accumulation of T cells in various nonlymphoid organs was differently affected by lack of IFN-γ, suggesting that IFN-γ influences T cell effector function to varying levels in different anatomical locations. Importantly, control of splenic T cell numbers during P. berghei ANKA infection depended on active IFN-γ-dependent environmental signals--leading to T cell apoptosis--rather than upon intrinsic alterations in T cell programming. To our knowledge, this is the first study to fully investigate the role of IFN-γ in modulating T cell function during P. berghei ANKA infection and reveals that IFN-γ is required for efficient contraction of the pool of activated T cells
