Abstract: High blood pressure (HBP) is the leading risk factor for mortality worldwide, but few adolescents know their blood pressure numbers. In youth, overweight is a key risk factorfor HBP. The objective of this study was to evaluate the capability of anthropometric indicators of obesity as predictors of HBP in adolescents. We conducted a cross-sectional study with 1,142 adolescents, both sex, 14-19 yearsold, from Santa Maria, RS, Brazil. The following anthropometric indicators were analyzed: body mass index (BMI), waist circumference (WC), waist-height ratio (WHR), and body adiposity index (BAI). The HBP was identified when above the 95 percentile for blood pressure. We used the analysis of Receiver Operating Characteristic (ROC) curves with 95% confidence interval, cutoff points with better accuracy were identified by sensitivity and specificity values. The prevalenceof HBP was 23.6%, and it was higher among boys (33.2%). The highest values for area under de ROC curves were: WHR (0.73; 95% CI: 0.69-0.77) and BAI (0.71;95% CI: 0.67-0.75) for girls. For boys: BMI (0.64; 95%CI: 0.60-0.68) and WHR (0.63; 95%CI: 0.59-0.68). The cutoff points proposed for WHR (boys=0.44; girls=0.45) presented de highest sensitivity and specificity values, both above 60%. The results of this study support that anthropometric measures of adiposity are valid in the identification of HBP in adolescents. Boys and girls with WHR ≥0.44and ≥0.45, respectively, are at high risk for HBP.

Abstract: the aim of this study was to verify the criterion and cross-validity of accelerometer thresholds for distinguishing different physical activity intensities and identifying sedentary behavior in children and adolescents. a systematic literature review was conducted using the pubmed, scopus, sports discus and web of science databases. inclusion criteria were: a) derivation and/or validation of accelerometer thresholds related to intensity of physical activity in youth (age 2 to 18 years); b) use of indirect calorimetry or direct observation as the reference method; c) original research articles published in english, portuguese or spanish. nineteen studies were selected. the accelerometers most often investigated were actigraph, rt3 and actical. thresholds showed good to moderate validity in the calibration phase (sensitivity = 68 to 100%; specificity = 61 to 100%). generalizability of the thresholds was higher when they were tested on independent samples (kappa = 0.72 to 0.91; sensitivity = 79 to 94%; specificity = 72 to 98%) than during independent activities (kappa = 0.46 to 0.71; sensitivity = 27 to 97%; specificity = 52 to 95%). one calibration study tested the validity of thresholds in independent samples and activities, and only one threshold validation study was found. in conclusion, limited information is available on the generality of accelerometer thresholds for physical activity monitoring in children and adolescents. validation studies are needed to identify appropriate thresholds for each type of accelerometer.

Abstract: objective: to evaluate the intensity and duration of physical efforts in physical education classes in primary and secondary school. methods: school-based cross-sectional study carried out by means of the observation of 218 physical education classes, including a total of 272 students (each one of the students was evaluated three times). the study was carried out in the city of pelotas (southern brazil), between august and december 2009. in order to evaluate the intensity of the efforts, accelerometers were used and the following cut-off points were adopted (in counts per minute): sedentary activities (0-100), light activities (101-2,000), moderate (2,001-4,999), vigorous (5,000-7,999), and very vigorous activities (>8000). results: the mean duration of the classes was 35.6 minutes (sd 6.0). the mean proportion of time spent in moderate to vigorous physical activity was 32.7% (sd 25.2). boys (44.1%) were involved significantly more in moderate to vigorous physical activity as compared to girls (21.0%; p<0.01). students who practice physical activities outside the classes participated more in moderate to vigorous physical activity in the physical education classes. conclusions: besides the fact that physical education classes have a short duration, students practice moderate to vigorous physical activity during one third of the class, with a poor significant contribution to students' level of physical activity.

Abstract: maintaining good health depends on, amongst other factors, of an adequate salivary flow1,2,3. damage caused by obstruction, trauma or surgical removal of the salivary glands may lead to alterations in the saliva production. any reduction in the salivary flow may result in harmful consequences to the living organism. this project was developed in order to enlighten the knowledge about the mechanisms that involve the regeneration of the rat submandibular gland (smg) submitted to a partial lobe excision. study design: experimental. material and method: archived sections of rat submandibular glands of 15, 16, 17, 18 and 19 days of fetal life, and twenty male rats aging 30 or 60 days were utilized. following anesthesia, the inferior third of the left lobe of the smg of each animal was removed. each animal was then left for recovery during 2, 3, 7 or 15 days, when were euthanazied and the glands removed, fixed in methacarn solution, parafinated, and with sections of 5 ?m under microtomy. staining was either done by hematoxilin/eosin or by periodic schiff acid (pas). results: it was observed that the regenerative process occurred early and in all the specimens studied. it was similar to the aspect verified in the normal glandular development, and more pronounced at the 30-day rat. the cytodifferentiation represented by the neutral mucin labeling by the pas, initially discrete, later on reaching its highest peak, and finally reducing its expression, having its place of initial establishment being changed. conclusion: based on the results, it was possible to conclude that the regenerative process of the rat excised smg is stable, permanent and gradual, following determined stages.
