Endothelial Wall Thickness, Cardiorespiratory Fitness And Inflammatory Markers In Obese And Non-obese Adolescents.
Increased carotid intima-media thickness (c-IMT) is considered a marker of early-onset atherosclerosis and it has been found in obese children and adolescents, but the risk factors associated with this population remain to be elucidated. To compare and verify the relationship between c-IMT, metabolic profile, inflammatory markers, and cardiorespiratory fitness in obese and non-obese children and adolescents. Thirty-five obese subjects (19 boys) and 18 non-obese subjects (9 boys), aged 10-16 years, were included. Anthropometry, body composition, blood pressure, maximal oxygen consumption (VO2max), and basal metabolic rate were evaluated. Serum glucose, insulin, homeostasis model assessment of insulin resistance (HOMA-IR), blood lipids, C-reactive protein (CRP), and adiponectin were assessed. c-IMT was measured by ultrasound. The results showed that c-IMT, triglycerides, insulin, HOMA-IR, and CRP values were significantly higher in the obese group than in the non-obese group, and high-density lipoprotein cholesterol (HDL-c), adiponectin, and VO2max values were significantly lower in the obese group than in the non-obese group. The c-IMT was directly correlated with body weight, waist circumference, % body fat, and HOMA-IR and inversely correlated with % free fat mass, HDL-c, and VO2max. Our findings show that c-IMT correlates not only with body composition, lipids, insulin resistance, and inflammation but also with low VO2max values in children and adolescents.1847-5

2 nd Brazilian Consensus on Chagas Disease, 2015
Abstract Chagas disease is a neglected chronic condition with a high burden of morbidity and mortality. It has considerable psychological, social, and economic impacts. The disease represents a significant public health issue in Brazil, with different regional patterns. This document presents the evidence that resulted in the Brazilian Consensus on Chagas Disease. The objective was to review and standardize strategies for diagnosis, treatment, prevention, and control of Chagas disease in the country, based on the available scientific evidence. The consensus is based on the articulation and strategic contribution of renowned Brazilian experts with knowledge and experience on various aspects of the disease. It is the result of a close collaboration between the Brazilian Society of Tropical Medicine and the Ministry of Health. It is hoped that this document will strengthen the development of integrated actions against Chagas disease in the country, focusing on epidemiology, management, comprehensive care (including families and communities), communication, information, education, and research
Peak oxygen uptake responses to training in obese adolescents: a multilevel allometric framework to partition the influence of body size and maturity status
The influence of body size and maturation on the responses in peak oxygen uptake (VO2) to a 12-week aerobic training and nutritional intervention in obese boys (n = 30; 10-16 years) was examined using multilevel allometric regressions. Anthropometry, sexual maturity status, peak VO2, and body composition were measured pre- and postintervention. Significant decrements for body mass, body mass index z-score, and waist circumference and increments for stature, fat-free mass, and peak oxygen uptake were observed after intervention. Partitioning body size on peak VO2, the responses of the individuals to training were positive (11.8% to 12.7% for body mass; 7.6% to 8.1% for fat-free mass). Body mass and fat-free mass were found as significant explanatory variables, with an additional positive effect for chronological. The allometric coefficients (k') in the initial models were k' = 0.883 and k' = 1.058 for body mass and fat-free mass, respectively. The coefficients decreased when age was considered (k' = 0.530 for body mass; k' = 0.860 for fat-free mass). Including maturity indicator in the models was not significant, thus the influence of variability in sexual maturity status in responses to exercise-based intervention in peak VO2 may be mediated by the changes in body dimensions

Effects of polymorphisms in APOB, APOE, HSD11ÎČ1, PLIN4, and ADIPOQ genes on lipid profile and anthropometric variables related to obesity in children and adolescents
Abstract Genes can influence lipid profile and anthropometric variables related to obesity. The present study aimed to verify if variants of the APOE, APOB, ADIPOQ, HSD11ÎČ1, and PLIN4 genes are associated with lipid levels or anthropometric variables in a sample comprised of 393 Euro-Brazilian children and adolescents. DNA was genotyped by TaqMan allelic discrimination assay. The Δ4 and Δ2 alleles of the APOE gene were associated respectively with lower high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C) levels (p=0.015 and p=0.012, respectively), while the Δ3 allele was associated with higher abdominal circumference (p=0.0416) and excess weight (p=0.0001). The G allele (rs846910) of the HSD11ÎČ1 gene was also associated with excess weight (p=0.039). No other association was found. Our results indicate that the Δ4 and Δ2 alleles could contribute to lower HDL-C and LDL-C levels, respectively, furthermore, the Δ3 allele and the G allele (rs846910) of HSD11ÎČ1 gene may be risk factors for excess of weight.These findings are very important because we observed that some genetic variants influence the lipid profile and anthropometric variables early in life

Crystal structure of two new polymeric copper(II) complexes active against Trypanosoma cruzi
We report here the characterization of two new polymeric copper(II) complexes containing 2-chlorobenzhydrazide (2-CH) and two N,N-donor ligands, namely, 1,10-phenanthroline (phen) and 4-4âČ-dimethoxy-2-2âČ-bipyridine (dmb). The structure of a new polymeric copper(II) complex in which a perchlorate anion acts as a bridge ligand is discussed in detail. In both complexes, spectral data reveals a bidentate coordination mode for hydrazide, perchlorate and N,N-donor ligand. These metal complexes and their free ligands were evaluated for their trypanocidal and cytotoxic activities and the complex with 1,10-phenanthroline has been much more active than benznidazole, a drug used in the treatment of Chagas disease. Keywords: Copper(II) complexes, Crystal structure, Trypanosoma cruzi, Cytotoxic activit
Crystal structure, anti-trypanosoma cruzi and cytotoxic activities of Cu(II) complexes bearing beta-diketone and alpha-diimine ligands
Three novel copper(II) complexes were synthesized: [Cu(tfa)(2)] (I), [Cu(tfa)(dmb)(NO3)]center dot 1.5H(2)O (II) and [Cu(tfa)(nphen)(NO3)] (III), where tfa = 4,4,4-trifluoro-1-(2-furyl)-1,3-butanedione, nphen = 5-nitro-1,10-phenanthroline and dmb = 4,4-dimethoxy-2,2-bipyridine. They were characterized by elemental analysis, conductivity measurements, FT-IR, UV-Vis and single-crystal X-ray diffraction. The X-ray crystal structures of I, II and III reveal that the beta-diketone coordinates via the oxygen atoms, while the heterocyclic bases coordinate via their two nitrogen atoms. The cytotoxic activity of I, II and III was investigated in two tumor cell lines (Ehrlich tumor and sarcoma 180) and in a non-tumor cell line (myoblast C2C12). Complex DI exhibited good activity (IC50 (Ehrlich) = 15.75 mu M and IC50 (sarcoma )180 = 16.90 mu M) and selectivity (SI > 4) in both tumor cell lines. Subsequently, it was found that III also present good activity against Trypanosoma cruzi499CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTĂFICO E TECNOLĂGICO - CNPQCOORDENAĂĂO DE APERFEIĂOAMENTO DE PESSOAL DE NĂVEL SUPERIOR - CAPESFUNDAĂĂO DE AMPARO Ă PESQUISA DO ESTADO DE MINAS GERAIS - FAPEMIGFUNDAĂĂO DE AMPARO Ă PESQUISA DO ESTADO DE SĂO PAULO - FAPESP305190/2017-2nĂŁo temnĂŁo tem2016/08823-4; 2013/07581-
