Effects of a Low Dose of Fish Oil on Inflammatory Markers of Brazilian HIV-Infected Adults on Antiretroviral Therapy: A Randomized, Parallel, Placebo-Controlled Trial.

Background: The benefits of antiretroviral therapy for HIV-infected subjects have been limited by an increased risk of metabolic and cardiovascular diseases. The objective of this study was to assess the effects of a low dose of marine omega-3 fatty acids on inflammatory marker concentrations in HIV-infected subjects under antiretroviral therapy (ART).

Methods: This was a randomized, parallel, placebo-controlled trial that investigated the effects of 3 g fish oil/day (540 mg of eicosapentaenoic acid-EPA plus 360 mg of docosahexaenoic acid-DHA) or 3 g soy oil/day (placebo) for 24 weeks in 83 male and non-pregnant female HIV-infected adults on ART.

Association between weight at birth and body composition in childhood: A Brazilian cohort study.

Background And Aim: Previous studies have shown that the association between birth weight and obesity later in life apparently follows a U-shaped curve. However, due to the continuous increase of mean birth weight in several countries worldwide, it is expected that higher birth weight will play a more important role as a risk factor for further obesity than low birth weight. This study investigated the association between birth weight and body composition of children in order to establish their relationship in an earlier period of life.

Vitamin E concentrations in adults with HIV/AIDS on highly active antiretroviral therapy.

HIV/AIDS patients are probably more predisposed to vitamin E deficiency, considering that they are more exposed to oxidative stress. Additionally, there are an extensive number of drugs in the highly active antiretroviral therapy (HAART) regimens that may interfere with vitamin E concentrations. The objective of this study was to compare serum concentrations of alpha-tocopherol in 182 HIV/AIDS patients receiving different HAART regimens.

[Prevalence of preterm birth according to birth weight group: a systematic review].

Objective: To estimate the prevalence of preterm birth by categories of birth weight, and to obtain an equation to correct the estimates.

Methods: Systematic review of the Brazilian literature published from 1990 to 2012, to identify studies with primary collection of data on birth weight and gestational age. Twelve studies were selected and contributed for tabulations of preterm prevalence according to 100 g birth weight categories.

Vitamin A and beta-carotene concentrations in adults with HIV/AIDS on highly active antiretroviral therapy.

Micronutrient deficiency is a common condition in HIV-infected individuals and may occur in all stages of the disease. The objective of this cross-sectional study was to compare the concentrations of vitamin A and beta-carotene, micronutrients related to immunity and oxidative stress, in 182 adults with HIV/AIDS, under different highly active antiretroviral therapy (HAART) regimens. Patients were divided into 3 groups according to their HAART regimen: combination of nucleoside analog reverse transcriptase inhibitors (NRTIs) and non-NRTIs; combination of NRTIs, protease inhibitors, and ritonavir; combination of NRTIs and other classes.

Effects of fish oil on lipid profile and other metabolic outcomes in HIV-infected patients on antiretroviral therapy: a randomized placebo-controlled trial.

Although antiretroviral therapy has revolutionized the care of HIV-infected patients, it has been associated with metabolic abnormalities. Hence, this study was planned to investigate the effects of fish oil on lipid profile, insulin resistance, and body fat distribution in HIV-infected Brazilian patients on antiretroviral therapy, considering that marine omega-3 fatty acids seem to improve features of the metabolic syndrome. We conducted a randomized, parallel, placebo-controlled trial that assessed the effects of 3 g fish oil/day (540 mg of eicosapentaenoic acid plus 360 mg of docosahexaenoic acid) or 3 g soy oil/day (placebo) on 83 HIV-infected Brazilian men and non-pregnant women on antiretroviral therapy.

The influence of vitamin A supplementation on iron status.

Vitamin A (VA) and iron deficiencies are important nutritional problems, affecting particularly preschool children, as well as pregnant and lactating women. A PubMed (National Library of Medicine, National Institutes of Health, Bethesda, MD, USA) literature review was carried out to search for clinical trials published from 1992 to 2013 that assessed the influence of vitamin A supplementation on iron status. Simultaneous use of iron and vitamin A supplements seemed to be more effective to prevent iron deficiency anemia than the use of these micronutrients alone.
