Dietary intake of community-based HIV-1 seropositive and seronegative injecting drug users.

Dietary intake was assessed in a subsample of a cohort of inner-city injecting drug users (IDUs). In this population of predominantly African-American IDUs, including both HIV -1-infected and noninfected men and women, a food frequency questionnaire (FFQ) and a 24-h recall were administered. One hundred seven volunteers participated. Although total caloric intake was consistently higher with the food frequency method, percent of total calories from fat, protein, and carbohydrates were similar between the FFQ and 24-h recall. Spearman's correlations for agreement between the 24-h recall and the FFQ ranged from 0.22 for vitamin E to 0.52 for carbohydrates. HIV-1 seropositives reported higher protein (p = 0.05) and fat (p = 0.02) consumption than seronegatives according to the 24-h recall. The difference in total fat consumption was due to higher intakes of saturated and monounsaturated fats (p = 0.01). Median intakes of vitamins B2 and B12, pantothenic acid (p < or = 0.05), phosphorous (p < or = 0.01), and selenium (p < or = 0.005) were also greater in HIV-1 seropositives. Reported intake of vitamins A and E, calcium, and zinc were below the recommended daily allowances for both HIV-1 seropositives and seronegatives. Although intakes of most nutrients appeared adequate for the group as a whole, extreme ranges were observed and may be the result of imbalanced food selections and day to day variation. Food group analysis indicated low intakes of fruits, vegetables, milk, and milk products. More research is needed to fully understand the implication of dietary habits and nutritional status in the free-living HIV-1-infected and noninfected IDUs.

Asthenia--does it exist in space?

OBJECTIVE: First popularized as neurasthenia in the late 1800s by American George Beard, asthenia has been viewed by Russian psychologists and flight surgeons as a major problem that affects cosmonauts participating in long-duration space missions. However, there is some controversy about whether this syndrome exists in space; this controversy is attributable in part to the fact that it is not recognized in the current American psychiatric diagnostic system. METHODS: To address this issue empirically, we retrospectively examined the data from our 4 1/2-year, NASA-funded study of crew member and mission control interactions during the Shuttle/Mir space program. Three of the authors identified eight items of stage 1 asthenia from one of our measures, the Profile of Mood States (POMS). Scores on these items from 13 Russian and American crew members were compared with scores derived from the opinions of six Russian space experts. RESULTS: Crew members' scores in space were significantly lower than the experts' scores on seven of the eight items, and they generally were in the "not at all" to "a little" range of the item scales. There were no differences in mean scores before and after launch or across the four quarters of the missions. There were no differences in response between Russian and American crew members. CONCLUSIONS: We could not demonstrate the presence of asthenia in space as operationally defined using the POMS. However, the POMS addresses only emotional and not physiological aspects of the syndrome, and the subject responses in our study generally were skewed toward the positive end of the scales. Further research on this syndrome needs to be done and should include physiological measures and measures that are specific to asthenia.
