Pay-for-performance (P4P) and public quality-reporting programs can increase the quality of health care for the services being measured. However, unless carefully designed, these programs may have the unintended consequence of increasing racial and ethnic disparities. This paper describes ways in which P4P and public reporting programs may increase disparities and suggests ways in which programs might be designed that will make them likely to reduce, or at least not increase, disparities.

Twenty-four obese women were randomly assigned to 1 of 2 group treatments: behavioral choice treatment (BCT) or traditional behavioral treatment (TBT). BCT uses decision theory to promote moderate behavior change that can be comfortably, and therefore permanently, maintained. Groups completed a moderate-intensity walking program and obtained feedback from computerized eating dairies. The TBT group evidenced greater weight loss at posttreatment. However, the TBT group also evidenced a trend to regain weight, whereas the BCT group continued a slow weight loss during follow-up. Exercise followed a similar pattern. Both groups decreased in restraint and increased in self-esteem.

There has been considerable debate concerning the benefits of children participating in weight training programs. With the potential benefits of such training in specific rehabilitation regimens, the safety/efficacy of weight training is a topic in need of scientific study. Fifty-two experimental and 39 control subjects participated in this study. A 2 x 2 x 2 (gender by treatment by Tanner stage) ANOVA was used to examine pre- to post-test differences in six strength measures, eight anthropometric measures, five motor performance measures, and one flexibility measure associated with participation in a 12-week progressive resistance programme. In addition, safety of the weight training programme was examined. For strength differences, there were two significant main effects favouring strength gains in males and four favouring the experimental group. For anthropometric changes, 3-way interactions occurred that were not easily explained. However, the predominant main effect was treatment; the experimental group generally experienced gains in body segment girths with decreases in skinfold thickness. For motor performance, the experimental group had greater improvements in three of five parameters. The experimental group also had significantly greater gains in flexibility. The weight training programme was associated with only one injury. These findings support the general observation that physical benefits can be gained safely by children who participate in a weight training programme.

The nucleotide sequences of the genes encoding the acetate-inducible glyoxylate cycle enzyme isocitrate lyase from the ascomycete fungi Aspergillus nidulans (acuD) and Neurospora crassa (acu-3) are presented. The respective A. nidulans and N. crassa genes are interrupted at identical positions by two introns and encode proteins of 538 and 543 amino acids, which have 75% identity. The predicted protein sequences do not demonstrate the C-terminal tripeptide S-K-L that has been implicated in peroxisomal targeting and found in the glyoxysomally located enzyme malate synthase from the same species. However, the protein sequences do exhibit a partial repeat which, in common with malate synthase, is located in regions that are absent from, or non-homologous with, the E. coli enzyme, which is not compartmentalized.
