Over the past 100 years, advances in pharmaceutical and medical technology have reduced the burden of communicable disease, and our appreciation of the mechanisms underlying the development of noncommunicable disease has broadened. During this time, a number of studies, both in humans and animal models, have highlighted the importance of maintaining an optimal diet during pregnancy. In particular, a number of studies support the hypothesis that suboptimal maternal protein and fat intake during pregnancy can have long-term effects on the growing fetus, and increase the likelihood of these offspring developing cardiovascular, renal, or metabolic diseases in adulthood. More recently, it has been shown that dietary intake of a number of micronutrients may offset or reverse the deleterious effects of macronutrient imbalance. Furthermore, maternal fat intake has also been identified as a major contributor to a healthy fetal environment, with a beneficial role for unsaturated fats during development as well as a beneficial impact on cell membrane physiology. Together these studies indicate that attempts to optimise maternal nutrition may prove to be an efficient and cost-effective strategy for preventing the development of cardiovascular, renal, or metabolic diseases.

Australian clandestine drug laboratories are constantly utilising alternative methods to produce methamphetamine, in part as restrictions are placed by Government on, for example, chemicals such as phenyl-2-propanone (P2P) (in the early 1980s), or on pseudoephedrine-containing pharmaceuticals, from the mid-2000s. This paper discusses the nitro-aldol reaction occurring between nitroethane and benzaldehyde, which can be utilised in a number of differing routes, in the presence of different bases. The resulting products, namely phenyl-2-nitropropene (P2P pathway) and 2-nitro-1-phenyl-1-propanol (ephedrine pathway) are directly dependant on which base is used; as such, the base may be used to provide an indication of a possible manufacture pathway of methamphetamine at a clandestine laboratory.
