title: Plasma concentrations of retinol in obese children and adolescents: relationship to metabolic syndrome components

description: Objective: To evaluate obese children and adolescents' retinol plasma levels and to correlate them with metabolic syndrome components.Methods: Cross-sectional study with 61 obese children and adolescents (body mass index Z score - ZBMI&gt;+2). Pubertal development, arterial blood pressure, body weight and height for nutritional classification and waist circumference were obtained. A 15mL blood sample was collected (after a 12-hour fasting in a low luminosity room) for retinol determination (cut-off inadequate if &lt;30µg/dL), lipid profile (HDL-c, LDL-c, and triglycerides), oral glucose tolerance test (fasting and 120 minutes) and for high sensitivity C-reactive protein. Spearman correlation and multiple linear regression were used in the statistical analysis.Results: Mean age was 10.7±2.7 years. There was a predominance of male gender 38/61 (62%) and pre-pubertal 35/61 (57%) subjects. The average plasmatic retinol was 48.5±18.6ug/dL. Retinol deficiency and severe obesity were observed in 6/61 (10%) and 36/61 (59%), respectively. Glucose level at 120 minutes was the independent and predictive variable of plasma retinol levels [β=-0.286 (95%CI -0.013 - -0.001)].Conclusions: An independent and inverse association between plasma retinol levels and glucose tolerance was observed, suggesting an important contribution of this vitamin in the morbidities associated to obesity in children and adolescents.

title: Body image in different periods of adolescence

description: Objective: To analyze body image in different periods of adolescence.Methods: This cross-sectional study enrolled students aged ten to 19 years old of public schools in small districts of Minas Gerais, Southeast Brazil. The Body Shape Questionnaire (BSQ), the Body Dissatisfaction Assessment Scale for Teenagers and the Silhouette Scale for Teenagers (SST) were used. Adolescence phases were classified according to the subjects' ages. Weight and height were measured in order to calculate the body mass index and the nutritional status. Results were analyzed by logistic regression.Results: The study emolled 531 teenagers (318 females). The average age was 15.6±2.2 years and 84.6% were eutrophic. The prevalence of body dissatisfaction varied from 28.9% (BSQ) to 78.9% (SST). Overweight adolescents presented greater dissatisfaction (BSQ: OR 3.66, p&lt;0.001; SST: OR 4.108, p&lt;0.001). Dissatisfaction also occurred for females and those at the early adolescence (p&lt;0.05).Conclusions:A low prevalence of dissatisfaction with the body image was observed among adolescents in small towns of Minas Gerais; however, most of them wished a different silhouette than the current one. The results showed that younger adolescents had higher dissatisfaction than their peers, as well as female and overweighed adolescents.

title: Variables associated with family breakdown in healthy and obese/ overweigh adolescents

description: Objective: To evaluate the presence of family breakdown factors among eutrophic and overweight/obese adolescents.Methods:Cross-sectional study of 242 students aged between 14 and 19 years old, from a public school. Each student was weighed, measured and answered a questionnaire with closed questions addressing the presence of family breakdown factors. The adolescents were divided in two groups: euthophic and overweight/obese. The answers of both groups were compared by Fisher's exact and Mann-Whitney tests.Results: There was no statistically significant difference in the prevalence of the studied factors between the two groups. Comparing the number of positive answers (presence of family breakdown factors) and negative ones (absence of family breakdown factors), no difference was observed between the groups.Conclusions: The inclusion of a control group showed that factors of family breakdown, usually identified as associated with obesity in adolescents, may also be present in eutrophic adolescents.

title: Inappropriate eating behavior: a longitudinal study with female adolescents

description: Objective: To evaluate the inappropriate eating behaviors (IEB) of female adolescents over a one-year period.Methods:290 adolescents aged between 11 and 14 years old participated in the three research stages (T1: first four months, T2: second four months and T3: third four months). The Eating Attitudes Test (EAT-26) was applied to assess the IEB. Weight and height were measured to calculate body mass index (BMI) in the three study periods. Analysis of variance for repeated measures was used to analyze the data, adjusted for the scores of the Body Shape Questionnaire and the Brazil Economic Classification Criteria.Results:Girls at T1 showed a higher frequency of IEB compared to T2 (p=0.001) and T3 (p=0.001). The findings also indicated higher values for BMI in T3 in relation to T1 (p=0.04). The other comparisons did not show statistically significant differences.Conclusions:IEB scores of female adolescents declined over one year.

title: Effects of two programs of exercise on body composition of adolescents with Down syndrome

description: Objective: To investigate the effects of a 12 week aerobic and resistance exercise on body composition of adolescents with Down syndrome.Methods: A quasi-experimental study with 41 adolescents with Down syndrome, aged 15.5±2.7 years, divided into three groups: Aerobic Training Group (ATG; n=16), Resisted Training Group (RTG; n=15) and Control Group (CG; n=10). There were two types of training: aerobic, with intensity of 50-70% of the heart rate reserve 3 times/week, and resisted, with intensity of 12 maximum repetitions 2 times week. Both trainings were applied during a 12-week period. The percentage of fat evaluation was performed using plethysmography with Bod Pod(r)equipment. Waist circumference (WC), body weight and height were also measured. Paired t-test was used to compare variables before and after the exercise program.Results: The percentage of body fat did not change significantly for both groups that participated in the training intervention. However, CG showed a significant increase in this variable (31.3±7.2 versus 34.0±7.9). On the other hand, body mass index (BMI) and WC were significantly reduced for ATG (BMI: 27.0±4.4 and 26.5±4.2; WC: 87.3±11.1 and 86.2±9.7), while RTG and GC showed no differences in these variables.Conclusions: The aerobic and resisted training programs maintained body fat levels. ATG significantly reduced BMI and WC measures. Individuals who did not attend the training intervention increased their percentage of fat.

title: Asthma in children and adolescents in Brazil: contribution of the International Study of Asthma and Allergies in Childhood (ISAAC)

description: Objective: To assess asthma among Brazilian pediatric population applying the International Study of Asthma and Allergies in Childhood (ISAAC), an internationally standardized and validated protocol.Data sources: ISAAC was conceived to maximize the value of epidemiologic studies on asthma and allergic diseases, establishing a standardized method (self-applicable written questionnaire and/or video questionnaire) capable to facilitate the international collaboration. Designed to be carried out in three successive and dependent phases, the ISAAC gathered a casuistic hitherto unimaginable in the world and in Brazil. This review included data gathered from ISAAC official Brazilian centers and others who used this method.Data synthesis: At the end of the first phase, it has been documented that the prevalence of asthma among Brazilian schoolchildren was the eighth among all centers participating all over the world. Few centers participated in the second phase and investigated possible etiological factors, especially those suggested by the first phase, and brought forth many conjectures. The third phase, repeated seven years later, assessed the evolutionary trend of asthma and allergic diseases prevalence in centers that participated simultaneously in phases I and III and in other centers not involved in phase I.Conclusions:In Brazil, the ISAAC study showed that asthma is a disease of high prevalence and impact in children and adolescents and should be seen as a Public Health problem. Important regional variations, not well understood yet, and several risk factors were found, which makes us wonder: is there only one or many asthmas in Brazil?

title: Temporal variation of Radon measurements in three wells in the Phlegraean Fields, using LR-115 Type II Nuclear Track Detector

description: <strong>Radon-222 (222Rn), formed within the 238U chain by decay of 226Ra, is the main radioactivity source of groundwater. Radon has three radioactive isotopes but only 222Rn is of interest having a half-life of 3.8 days, since 219Rn and 220Rn are short-lived isotopes (3.8 s and 55.6 s, respectively).</strong> <strong>The values of radon and temperature measured in three wells in the Phlegraean Fields in the 1980s, 1990s and early 2000s are reported.</strong> <strong>The wells are: Damiani hot well, Costagliola cold well, Tortorelli hot well.</strong> <strong>Measur at Tortorelli were interrupted in 1993, because of technical problems, while for Damiani and Costagliola were interrupted in 2006</strong> <strong>To measure radon content we used the track-etch method. </strong> <strong>This technique uses a particle sensitive cellulose nitrate film (Kodak LR-115 type II) as the detector. The measured track density (Track/cm2 /day). </strong> <strong>A 2 x 4 cm strip of alpha-particle sensitive film is fixed into the internal top of a bell-shaped brass cylinder, long 0.2m, opened at its lower end, into which gas is permitted to flow. </strong> <strong>The cylinder was positioned about 30 cm above the water, so that the film strip can record the traces made by the radon expelled from the water.</strong> <strong>The method is commonly used in wells because water collects radon as it migrates through the rocks not only about the measurement point but for a wide area. </strong> <strong>The time interval between measurements was about 10-15 days for the cold well (Costagliola well) and about 7 days for the hot wells (Damiani and Tortorelli). </strong> <strong>The sensitive films were treated with 10% NaOH at 60°C for 90 minutes in the laboratory to enlarge the recorded alpha-tracks. The track shape depends on the energy and angle of incidence of alpha tracks</strong> <strong>Tracks were counted using a microscope with a magnification of 160X. </strong> <strong>Low radon content is detected in the cold well (Costagliola; temperature ranges between 20-27°C) , whilst radon contents in the hot wells (Damiani and Tortorelli; temperature 44°-52°C and 60-64°C, respectively).</strong> <strong>The well temperature was measured when the films were changed using a K-type thermocouple</strong>

title: Dataset - Generalization of deep recurrent optical flow estimation for particle-image velocimetry data

description: This is the official test datasets of "Generalization of deep recurrent optical flow estimation for particle-image velocimetry data" published in Measurement Science and Technology. Particle-Image Velocimetry (PIV) is one of the key techniques in modern experimental fluid mechanics to determine the velocity components of flow fields in a wide range of complex engineering problems. Current PIV processing tools are mainly handcrafted models based on cross-correlations computed across interrogation windows. Although widely used, these existing tools have a number of well-known shortcomings, including limited spatial output resolution and peak-locking biases. Recently, new approaches for PIV processing leveraging a novel neural network architecture for optical flow estimation called Recurrent All-Pairs Field Transforms (RAFT) have been developed. These have matched or exceeded the performance of classical, handcrafted models. While the RAFT-PIV method is a promising approach, it is important for the broader fluids community to more completely understand its empirical behavior and performance. To this end, in this study, we thoroughly investigate the performance of RAFT-PIV under varying image and lighting conditions. IWe consider applications spanning synthetic and experimental data, with a breadth and depth going far beyond currently available empirical results. The results for the wide variation of experiments included in this dataset shed new light on the capabilities of deep learning for PIV processing. This dataset is given as binary TFRECORD format.
