Fourier transform infrared spectroscopy for capsular serotype classification in pediatric patients with invasive infections.

Invasive pneumococcal disease (IPD) is a major cause of morbidity and mortality worldwide, particularly in the pediatric population (children and infants), with high rates of hospitalization and death. This study aimed to create and validate a classifier for serotyping using Fourier-transform infrared (FT-IR) spectroscopy as a rapid alternative to the classical serotyping technique. In this study, a database comprising 76 clinical isolates, including 18 serotypes (predominantly serotypes 19A, 6C, and 3) of from pediatric patients with IPD, was tested at a tertiary pediatric hospital in southern Brazil during 2016-2023.

High-risk clones of carbapenem resistant Klebsiella pneumoniae recovered from pediatric patients in Southern Brazil.

Carbapenem-resistant Klebsiella pneumoniae (CRKP) exhibit high mortality rates in pediatric patients and usually belong to international high-risk clones. This study aimed to investigate the molecular epidemiology and carbapenem resistance mechanisms of K. pneumoniae isolates recovered from pediatric patients, and correlate them with phenotypical data.

Outbreak of vancomycin-resistant Enterococcus faecium ST1133 in paediatric patients with acute lymphoblastic leukaemia from southern Brazil.

Objectives: We aimed to investigate an outbreak of vancomycin-resistant Enterococcus faecium (VREfm) in paediatric patients from Hospital Pequeno Príncipe. The susceptibility profile was determined, and whole-genome sequencing (WGS) was used to analyse the genetic context of the strains.

Methods: Five VREfm isolates were recovered from sterile sites and surveillance cultures of two paediatric patients with acute lymphoblastic leukaemia.

Analysis of Clostridioides difficile Infection in Children with Diarrhea in Two Hospitals in Southern Brazil.

Clostridioides difficile infection (CDI) has been increasingly observed in children, but there is a lack of epidemiological and molecular data on CDI in Latin America. This prospective cohort study aimed to investigate the role of CDI in children with diarrhea. It included 105 children with antimicrobial-associated diarrhea (AAD) and analyzed the molecular characteristics of strains isolated from two hospitals in southern Brazil between 2017 and 2020.

Evolution of beverage portion sizes consumed in Brazil between 2008 and 2018.

Objective: To describe the evolution of beverage portion sizes consumed in Brazil between 2008 and 2018.

Methods: Data from the dietary surveys of 2008-2009 and 2017-2018 Brazilian Household Budget Surveys, conducted with 34,003 and 46,164 individuals, respectively, were used to analyze the portion size of beverages. Food consumption data were used to group beverages according to nutritional characteristics, type and size of portions into eight groups: high-calorie soft drinks, fruit refreshments, alcoholic beverages, coffee/tea, fruit juices, milk and milk substitutes and ultra-processed milk-based beverages.

Psychosocial aspects related to fruit and vegetable consumption in adolescents.

This study aimed at assessing the association between psychosocial aspects and fruit and vegetable consumption in adolescents. Cross-sectional study developed with 327 adolescents from a public school in Brazil. A questionnaire developed for adolescents was applied to assess the influence of self-efficacy, family, peers, and body image on the consumption of fruits and vegetables.

Genotypic Diversity of Complex in Invasive Candidiasis at a Pediatric Tertiary Hospital: A 5-Year Retrospective Study.

Invasive candidiasis (IC) contributes to the morbidity and mortality of hospitalized patients and represents a significant burden to the healthcare system. Previous Brazilian studies have reported the presence of endemic sensu stricto genotypes causing candidemia and clonal transmission involving fluconazole-resistant isolates. We performed a 5-year retrospective analysis of IC cases in a Brazilian tertiary pediatric hospital and conducted a molecular investigation of sensu stricto.

Snacking habits of Brazilian adolescents: Brazilian National Dietary Survey, 2017-2018.

This study was aimed at describing the snack consumption among Brazilian adolescents. The Brazilian National Dietary Survey (2017-2018) is a nationwide representative cross-sectional study that collected food consumption data from 8264 adolescents (10 to 19 years old); data from one 24-h recall were used, in which all foods and beverages consumed throughout the day prior to the interview were described along with the amount, unit of measurement, time, place and occasion of consumption (breakfast, lunch, dinner or snack). Snacks were classified as follows: (a) Morning snack: "Snacks" consumed between 6 AM and 12 PM; (b) Afternoon snack: "Snacks" consumed between 1 PM and 5 PM; (c) Evening snack: "Snacks" consumed between 6 PM and 5 AM.

Lower airway microbiota and decreasing lung function in young Brazilian cystic fibrosis patients with pulmonary Staphylococcus and Pseudomonas infection.

Cystic fibrosis (CF) is a genetic disease caused by mutations in the cystic fibrosis transmembrane conductance regulator gene that leads to respiratory complications and mortality. Studies have shown shifts in the respiratory microbiota during disease progression in individuals with CF. In addition, CF patients experience short cycles of acute intermittent aggravations of symptoms called pulmonary exacerbations, which may be characterized by a decrease in lung function and weight loss.

Acquisition of food for away-from-home consumption in Brazil between 2002 and 2018.

The aim of the study was to assess the evolution of food acquisition for away from home consumption in Brazil from 2002 to 2018. The trend of food purchases for out-of-home consumption in Brazil was evaluated by comparing food purchase data from the Household Budget Surveys (HBS) of 2002-2003, 2008-2009, and 2017-2018. The frequency of food acquisition was estimated according to sociodemographic variables and the mean cost.

Evolution of out-of-home food consumption in Brazil in 2008-2009 and 2017-2018.

Objective: To describe the evolution of out-of-home food consumption in Brazil in 2008-2018.

Methods: We used the 2008-2009 and 2017-2018 data from the Inquéritos Nacionais de Alimentação (INA - National Food Surveys), conducted amid 34,003 and 46,164 individuals, to estimate the frequency of out-of-home food consumption and the contribution of this consumption to specific foods. Food consumption was analyzed using food records in the 2008-2009 INA and 24-hour recalls in 2017-2018.

Association between common mental disorders and dietary intake among university students doing health-related courses.

We interviewed 432 students enrolled at a public university in Fortaleza, the capital of the State of Ceará, between April and December 2018. The students were screened for CMD using the Self-Reporting Questionnaire (SRQ-20).

Invasive candidiasis: Risk factor for mortality in a pediatric tertiary care hospital in south of Brazil.

Background: Invasive candidiasis (IC) is a major cause of morbimortality in children. Previous studies described the clinical characteristics and risk factors for this infection; however, limited data are available on the predictors of mortality in these patients. In this context, we evaluated the risk factors associated with death due to IC in a pediatric tertiary care hospital in South of Brazil.
