Because weight loss typically consists of both fat and lean tissue, measurement of body composition for diagnostic purposes, although potentially useful, is not essential. Although several early studies demonstrated that mortality is related not just to loss of weight but also to depletion of lean tissue, a recent study performed in patients on ART suggested that weight loss was a better predictor of mortality than lean or fat tissue measured by bioelectric impedance.( 13 ) Nonetheless, there has been considerable interest in the measurement of body composition in patients with HIV infection, and such measurements can be useful in conjunction with well-maintained weight records to characterize an individual's response to various medical or nutritional interventions.
74 Secondly, this case is yet another of those all too frequent cases where, in order to impose a proper sentence on the Respondent, this Court has had to choose between the unfairness of unequal treatment of co-offenders and the injustice to the community of acquiescing in a second manifestly inadequate sentence because the Director of Public Prosecutions, while appealing in the case of the Respondent elected, or was not sufficiently organised, to appeal in the case of a co-offender. As the Respondent and Sayadi were both arrested on the same day and sentenced by the same judge some 2 weeks apart it is inconceivable that the Office of the Director of Public Prosecutions was not aware of the relationship between them. In that situation it is impossible to see any rational explanation for the bringing of an appeal in one case and not in the other.
