Article Synopsis
- - The study examined the prevalence of minimum dietary diversity (MDD) and ultra-processed food consumption among 4,354 Brazilian children aged 6-23 months, considering factors like sociodemographic variables and regional differences.
- - MDD was found in 63.4% of the children, with lower rates in regions like the North (54.8%) and among those with less educated caregivers or facing food insecurity, while 80.5% consumed ultra-processed foods, particularly in the North (84.5%).
- - Only 8.4% of children achieved MDD without ultra-processed foods, highlighting dietary challenges among vulnerable populations and emphasizing the need for improved nutrition policies for infants in Brazil.
Article Synopsis
- The study aimed to analyze the rates of cross-breastfeeding, human milk donation to milk banks, and the reception of milk from these banks among Brazilian mothers.
- Using data from the Brazilian National Survey on Child Nutrition (ENANI-2019), researchers focused on 5,831 mothers of children under two years who had breastfed, finding that 21.1% practiced cross-breastfeeding.
- Although 4.8% of mothers donated milk and 3.6% reported their children received donated milk, cross-breastfeeding poses health risks, highlighting the need for discussion around these practices in Brazil and globally.
Prevalence and predictors of vitamin D insufficiency in Brazilian children under 5 years of age: Brazilian National Survey on Child Nutrition (ENANI-2019).
Br J Nutr
January 2024
To analyse the association of socio-demographic and health factors with vitamin D insufficiency and 25-hydroxyvitamin D (25(OH)D) concentration in Brazilian children aged 6-59 months. Data from 8145 children from the Brazilian National Survey on Child Nutrition (ENANI-2019) were analysed. The serum concentration of 25(OHD)D was measured using a chemiluminescent immunoassay.

Objective: The objective of this work is to evaluate the influence of bacterial infection on biomarkers of OS (catalase [CAT], glutathione peroxidade [GPx], reduced glutathione [GSH]), markers of oxidative damage (protein carbonyls [PC], thiobarbituric acid reactive substances [TBARS]), together with the nutritional status and lung function in children with CF.
Methods: Cross-sectional study including CF group (CFG, n = 55) and control group (CG, n = 31), median age: 3.
Relationship between oropharyngeal dysphagia, nutritional status, antioxidant vitamins and the inflammatory response in adults and elderly: A cross-sectional study.
Clin Nutr ESPEN
August 2020
Background & Aim: Oropharyngeal dysphagia (OD) can lead to a deficiency of antioxidant micronutrients. The aim of the present study was to investigate the relation between OD and nutritional status, antioxidant vitamins (β-carotene, vitamin E and C) and serum markers of the inflammatory response [C-reactive protein, myeloperoxidase (MPO), nitric oxide metabolites (NOx), tumor necrosis factor-α, interleukin (IL)-1β and IL-6] in adults and elderly.
Methods: A cross-sectional study was conducted with 69 individuals: 22 in the control group (CG) and 47 in the OD group (ODG).
The aim of the present study was to evaluate the effect of cystic fibrosis and antibiotic therapy on intestinal microbiota composition and intestinal inflammation in children and adolescents. A cross-sectional controlled study was conducted with 36 children and adolescents: 19 in the cystic fibrosis group (CFG) and 17 in the control group (CG) matched for age and sex. The CFG was subdivided based on the use of antibiotic therapy (CFAB group) and non-use of antibiotic therapy (CFnAB group).

Understanding the role of intestinal dysbiosis in chronic lung disease progression will provide opportunities to design early interventions to improve the course of the disease. Gut microbiota is established within the first 1 to 3 years of life and remains relatively stable throughout the life span.

Subjects/methods: A randomized, placebo-controlled, double-blind, clinical-trial was conducted with control group (CG, n = 17), placebo-CF-group (PCFG, n = 19), synbiotic CF-group (SCFG, n = 22), PCFG negative (n = 8) and positive (n = 11) bacteriology, and SCFG negative (n = 12) and positive (n = 10) bacteriology.
Background: Rotavirus (RV) induces diarrhoea through a sequence of enterotoxic and cytotoxic effects. The former are NSP4-dependent, induce calcium-dependent chloride secretion and involve oxidative stress. Diosmectite (DS) is a natural clay that has been recommended as an active therapy for diarrhoea, but the mechanism of its effect is not clear.

Methods: from September 2009 to January 2014, 445 men underwent prostate biopsy in a radiology service. We excluded from the study patients with diseases that could compromise the data analysis, who had undergone prostatic resection or used 5-alpha-reductase inhibitors.
