Faculty perspectives of health promotion in allied health curricula: results of a national survey.

More knowledge and skills related to health promotion/disease prevention are being required of health professionals. Allied health graduates entering the workforce will need academic preparation in these areas. This study assessed faculty perspectives on the status of health promotion content in allied health programs by a survey of 524 program directors. A questionnaire gathered information about perception of importance, level of representation, and method of delivery of health promotion content. Response rate was 41%. The majority of participants thought this content area was important for their programs and was highly or moderately represented in their curricula. Level of representation was significantly associated with requirement for accreditation. Programs in the Northeast were more likely to think health promotion was important and those in the West were more likely to have it integrated into their curricula. The most common delivery modality was guest lecture. Allied health is adopting health promotion curricular content, but further study is needed to assess programs and faculty expertise and identify strategies to ensure greater consistency of delivering material.

Oxidative signalling and gene expression during lymphocyte activation.

We previously have demonstrated an obligatory requirement for intracellular reactive oxygen species (ROS) generation during T lymphocyte activation, and have proposed that ROS may act as signalling agents in the regulation of certain cellular processes, for example, during cell cycle entry. In order to test this hypothesis, we have been interested to determine which, if any, cell cycle entry events are affected by oxidative signalling. Given the requirement for both oxidative signalling and altered gene expression during the G0 to G1 phase transition, we have attempted to establish the extent to which oxidative signalling affects global gene expression patterns during cell cycle entry, and to isolate and characterize mRNAs whose expression patterns are responsive to oxidative signalling during this process. Using differential display in a phenotypic screening approach, we have identified 10 mRNA species whose expression patterns were altered in response to inhibition of oxidative signalling during cell cycle entry. The expression patterns of 4 of these 10 mRNAs were unaffected during cell cycle arrest caused by a different mechanism, cyclosporin A-induced interference with calcineurin-mediated signalling events, implying that the altered expression patterns seen were not simply a consequence of cell cycle arrest. This suggests that the expression of these 4 mRNAs is regulated by a mechanism both necessary for cell cycle entry and sensitive to oxidative signalling. RNAse protection assays confirmed that 2 of these 4 mRNAs were indeed responsive to redox regulation. These observations strongly suggest an involvement for oxidative signalling in the regulation of gene expression during the G0 to G1 phase transition, in peripheral blood mononuclear cells at least.
