Increase in new-onset type 1 diabetes diagnoses among Brazilian children and adolescents during the COVID-19 pandemic.

Objective: This study aimed to determine if there was a rise in new T1DM cases in children during the pandemic in a large metropolitan area in Brazil.

Methods: The authors conducted a cross-sectional study at five public tertiary care centers that specialize in diabetes in children, comparing all new T1DM cases (ages 0.5-18y) diagnosed from March 2020 to December 2021 (pandemic period, PP) with those from March 2018 to December 2019 (historical period, HP).

Case Report: New insights about clinical manifestations of patients with genetic variants.

GCK-MODY is a genetic condition characterized by alterations in the gene, which can include several types of inactivating genetic variants - ranging from missense and nonsense variants, and splice site variants, to small and large deletions and insertions in the gene. This disorder primarily affects glucose homeostasis and usually presents in heterozygous individuals. Although GCK-MODY is a well-studied condition, some variant carriers may manifest symptoms that deviate from the typical disease phenotype.

Health-related quality of life in patients with type 1 diabetes mellitus in the different geographical regions of Brazil: data from the Brazilian Type 1 Diabetes Study Group.

Background: In type 1 diabetes mellitus (T1DM) management, enhancing health-related quality of life (HRQoL) is as important as good metabolic control and prevention of secondary complications. This study aims to evaluate possible regional differences in HRQoL, demographic features and clinical characteristics of patients with T1DM in Brazil, a country of continental proportions, as well as investigate which variables could influence the HRQoL of these individuals and contribute to these regional disparities.

Methods: This was a retrospective, cross-sectional, multicenter study performed by the Brazilian Type 1 Diabetes Study Group (BrazDiab1SG), by analyzing EuroQol scores from 3005 participants with T1DM, in 28 public clinics, among all geographical regions of Brazil.

Glycemic control and lipid profile of children and adolescents undergoing two different dietetic treatments for type 1 diabetes mellitus.

Objective: To compare the glycemic control and lipid profile of children and adolescents undergoing two different dietetic treatments for type 1 Diabetes Mellitus assisted at the Children and Adolescent's Diabetes Mellitus Health Center-UFRJ.

Methods: A retrospective longitudinal study conducted between 2002 and 2006. We evaluated the same subjects in two different periods: after 1 year in TD and subsequently after 1 year in CCHO.

Ethnicity and young age influence the frequency of diabetic ketoacidosis at the onset of type 1 diabetes.

Diabetic ketoacidosis (DKA) may be present at the onset of type 1 diabetes (T1D), increasing both its morbidity and mortality. The aim of this study was to describe the frequency of this complication at the clinical presentation of T1D, as well as possible interfering factors in a multi-ethnic population from Brazil. We have reviewed the medical charts of 545 individuals with T1D diagnosed between 1968 and 2006 from two major local diabetes treatment centers.
