BACKGROUND Iron homeostasis contribute for the human immunodeficiency virus (HIV) pathogenesis. OBJECTIVES We assessed the iron intake pattern in antiretroviral naïve Brazilian men living with HIV correlating with clinical and nutritional parameters. METHODS The iron consumption mean was estimated according to a food frequency questionnaire (FFQ), and a 3-day food record (3dFR) submitted to the patients. HIV viral load, CD4+ T cell counts, serum iron, haematological and anthropometrics parameters were recorded. FINDINGS Fifty-one HIV-infected adult men naïve for antiretroviral therapy (ART) were enrolled. The mean age of participants was 35 (SEM ± 1.28) years old, with mean time of HIV-1 infection of 1.78 (0-16.36, min-max) years. Majority (41.18%) had complete secondary, and 21.57% had tertiary educational level. The income was around 1x (54.90%) to 2x (41.18%) minimum wage. Fifty-four percent showed normal weight, while 40% were overweight. The patients showed normal mean values of haematological parameters, and mean serum iron was 14.40 µM (SEM ± 0.83). The FFQ showed moderate correlation with the 3dFR (ρ = 0.5436, p = 0.0009), and the mean values of iron intake were 10.55(± 0.92) mg/day, recorded by FFQ, and 15.75(± 1.51) mg/day, recorded by 3dFR. The iron intake, recorded by FFQ, negatively correlated with serum iron (ρ = -0.3448, p = 0.0132), and did not have influence in the CD4+ T cell counts [e.B 0.99 (0.97-1.01, 95% confidence interval (CI), p = 0.2]. However, the iron intake showed a positive effect in HIV viral load [e.B 1.12 (1.02-1.25, 95%CI), p < 0.01]. MAIN CONCLUSIONS This study draws attention for the importance of iron intake nutritional counseling in people living with HIV. However, more studies are required to clarify the association between high iron intake and HIV infection and outcome.

RESUMO Objetivo: descrever o perfil de medicamentos orais padronizados em uma unidade hospitalar e verificar sua adequação quanto ao uso por cateteres enterais, de acordo com recomendações da literatura. Método: estudo descritivo, com dados sobre medicamentos coletados do Sistema de Dispensação do Serviço de Farmácia. As recomendações específicas para uso de tais medicamentos por cateteres enterais foram obtidas após busca em bases literárias, livros, manuais, guidelines e bulários. Resultados: dos 236 medicamentos orais dispensados, 86% estavam na forma sólida; destes, 32 eram "não trituráveis", havendo disponibilidade da forma líquida na instituição. Foram identificados 28 medicamentos com potenciais interações com a nutrição enteral. Sessenta porcento deles apresentavam recomendações específicas sobre sua administração por cateter enteral. Conclusão: a participação conjunta das equipes multidisciplinares de terapia nutricional e de assistência e a implementação de programas para treinamento contínuo constituem estratégias sugeridas para a prevenção de potenciais problemas na administração de medicamentos no espaço hospitalar.

ABSTRACT Objective: to describe the profile of standardized oral drugs at a hospital unit and assess their adequacy for use via enteral feeding tubes, according to recommendations from the literature. Method: descriptive study, with data on drugs collected from the Pharmacy Service Dispensing System. Specific recommendations for the use of these drugs via enteral feeding tubes were found after searches in literary databases, books, manuals, guidelines and package insert collections. Results: among the 236 dispensed oral drugs, 86% were in solid form; of those, 32 were "non-crushable", with the liquid form available at the institution. Twenty-eight drugs with potential interactions with enteral nutrition were identified. Sixty percent of those presented specific recommendations on their administration via enteral feeding tube. Conclusion: the joint participation of multidisciplinary nutritional therapy and care teams and the implementation of programs for continuous training are suggested strategies for the prevention of potential problems in the administration of drugs in the hospital setting.

RESUMEN Objetivo: describir el perfil de medicamentos orales estandarizados en una unidad hospitalaria y verificar su adecuación respecto del uso vía sondas gástricas, según recomendaciones de la literatura. Método: estudio descriptivo, con datos sobre medicamentos recolectados del Sistema de Dispensación del Servicio de Farmacia. Las recomendaciones específicas de uso por sondas gástricas fueron obtenidas por búsqueda en bases de literatura, libros, manuales, guidelines y vademécums. Resultados: De los 236 medicamentos orales dispensados, 86% se presentaban en forma sólida; de ellos, 32 eran "no triturables", existiendo disponibilidad de la forma líquida en la institución. Fueron identificados 28 medicamentos con potenciales interacciones con la nutrición enteral. El 60% incluía recomendaciones específicas sobre administración por sonda gástrica. Conclusión: la participación conjunta de equipos multidisciplinarios de terapia nutricional y de atención y la implementación de programas de capacitación permanente constituye estrategias sugeridas para prevenir potenciales problemas en administración de medicamentos en el ámbito hospitalario.

The effects of a protein-restricted diet (8% protein, 81% carbohydrate and 11% lipids) on Schistosoma mansoni infectivity, fecal egg excretion and intestinal egg distribution in Swiss (SW) mice were studied. Pregnant mice received a deficient diet from the middle of gestation until delivery. Seven-days-old mice were exposed to 50 cercariae (BH strain, Brazil). Offspring mice had a free access to the deficient diet since lactation until adulthood. The controls were fed with a commercial mice diet. A parasitological examination was performed between six and eight weeks post-infection while both groups were necropsied one week later. Mice on the experimental diet showed a significant loss in body weight. There was no significant difference (p > 0.05) in pre-patent period, kinetics of egg excretion and worm recovery from mice on either diet. Significant differences (p < 0.05) were found concerning to the percentage of deposited eggs in the distal segment of the small intestine from hosts on the experimental diet.Our data suggest that experimental malnutrition induced for a long term has no detrimental effect on the acute schistosomiais infection in SW mice.
