Multicenter Study Comparative Study
Structural and process indicators of nutritional care: a comparison between Austrian hospitals and nursing homes.
The aim of this study was to describe and compare structural and process indicators of nutritional care in Austrian hospitals and nursing homes. ⋯ The study demonstrated that nursing homes fulfilled more structural indicators and performed nutritional screening at admission more often than hospitals. Nevertheless, the prevalence of malnutrition was high in the two settings and a substantial number of malnourished patients/residents received no nutritional intervention at all. These results show the necessity for improvements in the nutritional care in Austria, for instance, through the routine use of nutritional screening tools followed by tailored nutritional interventions in patients/residents in need.

The BASA-ROT table: an arithmetic-hypothetical concept for easy BMI-, age-, and sex-adjusted bedside estimation of energy expenditure.
The rule of thumb (ROT) method is used to estimate energy expenditure (EE) at bedside. ROTs are fixed numbers of calories given daily per kilogram of body weight. Textbooks nevertheless indicate that age and body mass index (BMI) affect EE. This should also affect ROTs. We thus scrutinized the impact of BMI, age, and sex on ROTs, compared the results to the often used 25 kcal/kg ROT, and calculated a BMI-, age-, and sex-adjusted ROT table containing calories per kilogram in the basal state. ⋯ We found that both BMI and age significantly impacted ROT estimates. Thus, using one single fixed ROT for all patients independent of age and BMI does not seem appropriate. We consequently suggest a calculated table of BMI-, age-, and sex-adjusted ROTs where the results of resting EE were multiplied with 1.1, 1.2, and 1.3 and separately listed in the table to account for activity/stress factors.

Changes in dietary habits and eating practices in adolescents living in urban South Africa: the birth to twenty cohort.
To assess changes in the dietary habits and eating practices of a longitudinal cohort of adolescents over a 5-y period living in Soweto and Johannesburg. ⋯ Poor eating habits in all three environments were found; the participants' propensity for foods that were energy dense and micronutrient poor was high. This study also found that dietary patterns are well established by 13 y of age.

Higher dietary intake of long-chain omega-3 polyunsaturated fatty acids is inversely associated with depressive symptoms in women.
Experimental and observational data suggest that a higher dietary intake of long-chain omega-3 polyunsaturated acids may lead to a decreased risk of depressive disorders. We assessed multivariable-adjusted associations of fish consumption and dietary intakes of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) with depressive symptoms in a population-based sample of 3317 African-American and Caucasian men and women from the Coronary Artery Risk Development in Young Adults study. ⋯ Our findings suggest that dietary intakes of fish and long-chain omega-3 fatty acids may be inversely associated with chronic depressive symptoms in women.

Association between dietary fiber and markers of systemic inflammation in the Women's Health Initiative Observational Study.
Systemic inflammation may play an important role in the development of atherosclerosis, type 2 diabetes, and some cancers. Few studies have comprehensively assessed the direct relations between dietary fiber and inflammatory cytokines, especially in minority populations. Using baseline data from 1958 postmenopausal women enrolled in the Women's Health Initiative Observational Study, we examined cross-sectional associations between dietary fiber intake and markers of systemic inflammation (including serum high-sensitivity C-reactive protein [hs-CRP], interleukin-6 [IL-6], and tumor necrosis factor-alpha receptor-2 [TNF-alpha-R2]) in addition to differences in these associations by ethnicity. ⋯ These findings lend support to the hypothesis that a high-fiber diet is associated with lower plasma levels of IL-6 and TNF-alpha-R2. Contrary to previous reports, however, there was no association between fiber and hs-CRP among postmenopausal women. Future studies on the influence of diet on inflammation should include IL-6 and TNF-alpha-R2 and enroll participants from ethnic minorities.
