Prevalence of Functional Gastrointestinal Disorders in Brazilian Infants Seen in Private Pediatric Practices and Their Associated Factors.

Objectives: To assess the prevalence of the most frequent functional gastrointestinal disorders (FGIDs) in Brazilian infants seen in private pediatric clinics and their relationship with cesarean delivery, breastfeeding, and history of prematurity.

Methods: This cross-sectional study enrolled 5080 infants under 12 months old with routine visits in private pediatric clinics in Brazil. The mothers answered questions about the type of delivery, type of feeding (breast milk, infant formula, cow milk, mixed feeding), history of prematurity, and gastrointestinal symptoms.

Breastfeeding in infants seen in private pediatric practices and its relation with type of delivery and history of prematurity.

Objective: To describe the type of milk used to feed infants seen in private pediatric practices in Brazil. To evaluate the relationship between breastfeeding, type of delivery, and history of prematurity.

Methods: This is a cross-sectional and observational study that included 4929 infants in the first year of life seen in private pediatric practices in the five geographic regions of Brazil.

Tolerability and Effects of the Use of Energy-Enriched Infant Formula After Congenital Heart Surgery: A Randomized Controlled Trial.

Background: Undernutrition is a common problem among children with congenital heart disease (CHD) and may lead to poorer surgical outcomes. A higher intake of energy during the postoperative period of CHD surgery seems to be associated with better outcomes. This study aimed to investigate the effect of the use of energy-enriched formula (EE-formula) compared with normocaloric formula during 30 days after CHD surgery.

Prevalence of infection with cagA-positive Helicobacter pylori strains among children and adolescents in southern Brazil.

Context: Helicobacter pylori (H. pylori) has a worldwide distribution, but the prevalence of infection, virulence factors, and clinical presentation vary widely according to the studied population. In Brazil, a continental country composed of several ethnicities and cultural habits, the behavior of infection also appears to vary, as many other studies have shown.
