Given the importance of pigs as intermediate hosts for genetic reassortment [15] and their proven susceptibility to this strain, it is prudent that swine populations should also be protected to avoid their involvement in the epidemiology of the current pandemic virus.
Consequently, the selection of this vulnerable population was prudent and directly related to the problem of juvenile delinquency.
The choice to compare the present data to two major ethnicities in Asia, that is, Chinese and Indian, is prudent considering that these populations are those which have been considered by many implant designers as the normal population representing the populations of this region.
In U.S. populations, a "prudent" and a "western" dietary pattern have been identified (25), but associations with diabetes have again been rather modest (26, 27).
It would therefore be prudent to re-model population-wide folic acid intakes using more recent national survey data to assess the impact of the proposed fortification policy prior to its implementation.
Given the importance of ethnicity in influencing diabetes risk and its significance in a multi-ethnic population, it is prudent to determine its influence on a population-based risk prediction tool.
In this situation, it may be prudent to search for natural populations in which these associations are weaker or focus selection efforts on loci that are not pleiotropically regulated.
However, it would certainly be prudent to continue to monitor populations that might be at risk, given the apparent conflict of findings of studies published to date, which reinforces the need for carefully designed studies aimed at providing an explanation for results relating to nuclear installations, and for the observed patterns of childhood leukaemia more generally (e.g., COMARE, 2006).
Arguably, in the absence of better information, a prudent conservation strategy is to maintain population divergence generally until the specific targets of selection can be identified through further research.
However, given the long-term nature of projected climate change, it is also prudent to consider the responses of populations to environmental change over longer time scales.
