São Paulo, city-region: constitution and development dynamics of the São Paulo macrometropolis
This article deals with the emergence of the city-region in São Paulo (Brazil), called ‘macrometropolis’, and highlights some of the challenges facing this new territorial or spatial configuration in terms of globalisation and governance. It also stresses the productive changes that gave rise to it and sheds light on the constituent dynamics of the macrometropolis at different scales. The article affirms that metropolitan problems can no longer be interpreted without taking into account the new determinants of the macrometropolis of São Paulo, which implies considering the interaction of the metropolis with other urban centres bearing social, economic and environmental singularities.

Nutritional adaptation of women living with HIV: a pilot study.
The incidence of human immunodeficiency virus (HIV) infection in women worldwide is increasing rapidly. Assumptions about HIV-related immunologic and nutritional changes are primarily based on data derived from men infected with HIV. The article reports a pilot study designed to examine the immunologic and nutritional responses of a small group of women with HIV infection and to suggest the Roy adaptation model as a framework for understanding HIV-related changes in women. A cross-sectional descriptive design was used to study physiologic mode responses in women seropositive for HIV. Results indicated that the subjects had lower than normal total CD4+ counts. The mean body mass index and midarm muscle area of this cohort of women fell between the 50th and 75th percentiles, and the triceps skinfold thickness was slightly below the 50th percentile, compared with age-matched norms derived from NHANES II data. Although wasting and nutritional problems are common in men with HIV disease the results suggest that women at the midlevel of the disease may not yet have major problems with nutritional adaptation to HIV. Future studies using the Roy adaptation model with larger samples of women who are followed over time are needed to determine whether the decline in physiologic mode adaptation level noted in men infected with HIV is also experienced by women infected with HIV.
