AI Article Synopsis
- The study aimed to analyze trends in obesity, overweight, and thinness among Brazilian schoolchildren, focusing on differences by sex, age, and type of school using WHO and IOTF criteria.
- Conducted between 2002 and 2018/19, the surveys revealed a significant increase in obesity prevalence among children, particularly in public schools, with rates rising by 72% (IOTF) and 44% (WHO) over the period.
- The findings indicate that obesity is becoming more common, especially among children from public schools, while the prevalence of thinness did not significantly decrease during the same time span.
Article Abstract
Objective: To analyze the obesity, overweight, and thinness trends among Brazilian schoolchildren by sex, age group, and type of school according to World Health Organization (WHO) and International Obesity Task Force (IOTF) criteria.
Methods: We conducted four surveys between 2002 and 2018/19 involving schoolchildren aged 7-14 years from a state capital in southern Brazil. Weight status was classified using both WHO and IOTF criteria.
Results: In the total sample, obesity prevalence based on the IOTF and the WHO criteria were 72% and 44% higher in 2018/19 compared with 2002, respectively. Over the whole period, the obesity prevalence increased among children (WHO: 10.1% vs. 14.1%; IOTF: 5.0% vs. 8.3%), and those from public schools (WHO: 10.5% vs. 16.4%; IOTF: 5.6% vs. 10.1%). There was no significant reduction in thinness prevalence over the analyzed period.
Conclusion: Obesity prevalence remains on an upward trend in a state capital in southern Brazil, especially among children from public schools. A higher prevalence of overweight and obesity was observed using the WHO criteria compared with IOTF criteria.

Carbon dots in biosensing have advanced significantly, adding improvements to different detection techniques. In this study, an amperometric immunosensor for Salmonella Thyphimurium was designed using antibodies labeled with carbon dots (Cdots) from pequi almond (Caryocar brasiliensis). Cdots were synthesized by pyrolysis and characterized by FTIR, UV/fluorescence, electrochemistry, zeta potential, and transmission electron microscopy (TEM).

Introduction: Endothelin A (ETA) receptor activation is a driver of proteinuria, kidney inflammation, and fibrosis in IgA nephropathy (IgAN). Atrasentan, a selective ETA receptor antagonist, has potential to reduce proteinuria and preserve kidney function in IgAN. ALIGN (NCT04573478) is a phase 3, randomized, double-blind, placebo-controlled clinical trial of atrasentan in patients with IgAN at high risk of kidney function loss.

Background: The impact of ankyloglossia (tongue-tie) on breastfeeding outcomes may be overestimated and surgical treatment in newborns remains a controversial topic. The aim of the present study was to assess and quantify the impact of ankyloglossia in newborns on breastfeeding self-efficacy at 14 days of life.
Methods: A birth cohort study was conducted involving mothers and newborns soon after childbirth at a public hospital in the city of Canoas, southern Brazil.

Prozostrodontia is a clade of probainognathian cynodonts that exhibit several morphological innovations later inherited by mammals. The earliest representatives of this group have been found in the Upper Triassic deposits of southern Brazil. In this study, we report the discovery of a probainognathian cynodont from the Buriol site (São João do Polêsine, Rio Grande do Sul, Brazil), Hyperodapedon Assemblage Zone (Late Triassic).
