Consumption of ultra-processed foods is associated with dietary iron availability, anemia, and excess weight in socially vulnerable children.

Background & Aims: Eating habits during childhood have undergone significant changes, with a notable increase in the consumption of ultra-processed foods (UPF). This situation deserves attention, given the close relationship between UPF and adverse health outcomes. This is due to the nutritional composition of UPF, which has high levels of health-critical nutrients such as sugar, fat, and sodium, thus compromising the overall quality of the diet.

Molecular characterization of virulence and antimicrobial resistance profile of Shigella species isolated from children with moderate to severe diarrhea in northeastern Brazil.

Molecular characterization of virulence and antimicrobial resistance profiles were determined for Shigella species isolated from children with diarrhea in Fortaleza, Brazil. Fecal specimens were collected along with socioeconomic and clinical data from children with moderate to severe diarrhea requiring emergency care. Shigella spp.

Combination of different methods for detection of Campylobacter spp. in young children with moderate to severe diarrhea.

Campylobacter spp. were detected - using culture, ELISA, PCR, and qPCR - among children (0-36months) with moderate to severe diarrhea in Northeastern Brazil. Our data showed that either the qPCR alone or PCR along with ELISA might be an alternative to culture to diagnose Campylobacter due to their enhanced sensitivity.

Efficacy of a tetravalent dengue vaccine in children in Latin America.

Background: In light of the increasing rate of dengue infections throughout the world despite vector-control measures, several dengue vaccine candidates are in development.

Methods: In a phase 3 efficacy trial of a tetravalent dengue vaccine in five Latin American countries where dengue is endemic, we randomly assigned healthy children between the ages of 9 and 16 years in a 2:1 ratio to receive three injections of recombinant, live, attenuated, tetravalent dengue vaccine (CYD-TDV) or placebo at months 0, 6, and 12 under blinded conditions. The children were then followed for 25 months.

A critical comparison between the World Health Organization list of essential medicines for children and the Brazilian list of essential medicines (Rename).

Objective: To perform a critical comparison between the Brazilian national essential medicines list (Rename, 2012) with the list of essential medicines for children (LEMC, 2011) of the World Health Organization (WHO), regarding the differences among drugs and formulations listed for children.

Methods: The LEMC drugs were classified into four categories: 1) absent in Rename; 2) included in Rename but without any formulation suitable for children; 3) listed in Rename only in some formulations; 4) present in Rename in all formulations. The missing formulations were analyzed by therapeutic group.

Campylobacter jejuni infection and virulence-associated genes in children with moderate to severe diarrhoea admitted to emergency rooms in northeastern Brazil.

Campylobacter is an important cause of foodborne gastroenteritis. We determined the occurrence of Campylobacter jejuni and Campylobacter coli, using culture-based methods and PCRs targeting virulence-associated genes (VAGs) among children aged ≤14 years who were treated for diarrhoea at emergency rooms in northeastern Brazil. Genomic DNA was extracted directly from stool samples collected from 366 children.

Infectious diseases in paediatric pathology: experience from a developing country.

Infectious and parasitic diseases have always challenged man. Although many of them are typically seen in some areas of the world and can be adequately managed by just improving socioeconomic status and sanitary conditions, they are still quite prevalent and may sometimes be seen outside their original geographical areas. Human migration due to different reasons, tourism, blood transfusion and solid organ transplantation has created new concerns for health professionals all over the world.
