Trends and Factors Associated With Central Obesity in Schoolchildren in Florianópolis, Santa Catarina, Brazil: Cross Sectional Panel Study From 2002 to 2019.

Objective: This study aimed to assess the trend and factors associated with central obesity in four cross-sectional panels in schoolchildren aged 7-14 years between 2002 and 2019.

Methods: Waist circumference data were used to assess central obesity, and independent variables were gender, age, school shift (morning and afternoon), commuting to school method, mother's schooling, and family income. The chi-square test was used to assess the association between outcome and independent variables, and binary logistic regression was used to assess the predictors of central obesity and the effect size by odds ratio.

Chromoanagenesis Is Frequently Associated With Highly Complex Karyotypes, Extensive Clonal Heterogeneity, and Treatment Refractoriness in Acute Myeloid Leukemia.

Chromoanagenesis (CAG) encompasses a spectrum of catastrophic genomic events, including chromothripsis, chromoanasynthesis, and chromoplexy. We studied CAG in 410 patients with a diagnosis of acute myeloid leukemia (AML), 292 newly diagnosed (ND), and 118 refractory/relapsed, using optical genome mapping. CAG was identified by the presence of clusters (with 10 or more breakpoints) of structural abnormalities and/or segmental copy number alterations within one or more chromosomal regions.

Contemporary Approach to the Diagnosis and Classification of Intestinal T-cell Lymphomas.

We provide an overview of recent advances in the diagnosis and classification of intestinal T- and NK-cell lymphomas and lymphoproliferative disorders that primarily involve the gastrointestinal (GI) tract. It should be mentioned that systemic T- and NK-cell lymphomas can present initially in the GI tract but are not the focus of this review. Here, we focus on the clinical and pathologic findings of enteropathy-associated T-cell lymphoma, monomorphic epitheliotropic intestinal T-cell lymphoma, intestinal T-cell lymphoma not otherwise specified, indolent T-cell lymphoproliferative disorder of the GI tract and indolent NK-cell lymphoproliferative disorder of the GI tract (previously known as NK-cell enteropathy).
