Abstract
Accumulated evidence supports the contribution of genetic factors in modulating airway function, especially ancestry. We investigated whether genetic polymorphisms can affect lung function in a mixed Brazilian child population using the admixture mapping strategy through RFMix software version 1.5.4 (Stanford University, Stanford, CA, USA), followed by fine mapping, to identify regions whereby local African or European ancestry is associated with lung function measured by the forced expiratory volume in the first second (FEV1)/forced vital capacity (FVC) ratio, an indicator of airway obstruction. The research cohort included 958 individuals aged 4 to 11 years enrolled in the SCAALA (Social Change, Asthma, Allergy in Latin America) Program. We identified that African ancestry at 17q21.31, 10q22.2, and 2p23.1 regions was associated with lower lung function measured by FEV1/FVC p < 1.9 × 10-4. In contrast, European ancestry at 17q21.31 showed an opposite effect. Fine mapping pointed out 5 single nucleotide polymorphisms (SNPs) also associated in our replication cohort (rs10999948, rs373831475, rs8068257, rs6744555, and rs1520322). Our results suggest that genomic regions associated with ancestry may contribute to differences in lung function measurements in African American children in Brazil replicated in a cohort of Brazilian adults. The analysis strategy used in this work is especially important for phenotypes, such as lung function, which has considerable disparities in terms of measurements across different populations.

Abstract
UNLABELLED There is no objective way to monitor mechanical loading characteristics during exercise for bone health improvement. We developed accelerometry-based equations to predict ground reaction force (GRF) and loading rate (LR) in normal weight to severely obese subjects. Equations developed had a high and moderate accuracy for GRF and LR prediction, respectively, thereby representing an accessible way to determine mechanical loading characteristics in clinical settings. INTRODUCTION There is no way to objectively prescribe and monitor exercise for bone health improvement in obese patients based on mechanical loading characteristics. We aimed to develop accelerometry-based equations to predict peak ground reaction forces (pGRFs) and peak loading rate (pLR) on normal weight to severely obese subjects. METHODS Sixty-four subjects (45 females; 84.6 ± 21.7 kg) walked at different speeds (2-6 km·h-1) on a force plate-equipped treadmill while wearing accelerometers at lower back and hip. Regression equations were developed to predict pGRF and pLR from accelerometry data. Leave-one-out cross-validation was used to calculate prediction accuracy and Bland-Altman plots. Actual and predicted values at different speeds were compared by repeated measures ANOVA. RESULTS Body mass and peak acceleration were included for pGRF prediction and body mass and peak acceleration transient rate for pLR prediction. All pGRF equation coefficients of determination were above 0.89, a good agreement between actual and predicted pGRFs, with a mean absolute percent error (MAPE) below 6.7%. No significant differences were observed between actual and predicted pGRFs at each walking speed. Accuracy indices from our equations were better than previously developed equations for normal weight subjects, namely a MAPE approximately 3 times smaller. All pLR prediction equations presented a lower accuracy compared to those developed to predict pGRF. CONCLUSION Walking pGRF and pLR in normal weight to severely obese subjects can be predicted with moderate to high accuracy by accelerometry-based equations, representing an easy and accessible way to determine mechanical loading characteristics in clinical settings.

Abstract
UNLABELLED Physical activity (PA) is recognized as having many health benefits. Despite of all the efforts, the majority of the overweight adolescents still present low levels of PA. PA consultation can be a cost-effective way of enhancing PA and improve weight status among overweight adolescents. The main aim of this study was to analyze whether adolescents attending a PA consultation in a clinical setting show more therapeutic success at 6 months, based on body mass index (BMI) z-score and waist circumference (WC), compared to those only followed by the pediatrician and nutritionist. Clinical records from 396 patients were analyzed: PA consultation (PAc) group, n = 198; standard consultation (STc) group, n = 198. Baseline differences between groups were analyzed using chi-square and independent sample t tests. Changes within groups and between groups were analyzed using paired sample t tests and independent sample t tests, respectively. Patients in both groups decreased their BMI z-score. The PAc has shown a higher decrease in the BMI z-score (PAc -0.12, p < 0.0001; STc -0.05, p < 0.0001). The WC of the PAc group has increased 2.2 cm less than the one of the STc group (p < 0.005). The difference in waist-to-height ratio between the PAc and STc groups was of 0.015 (p < 0.005), showing a trend to decrease in the PAc group (-0.005, p = 172). CONCLUSION Although the success of adolescent obesity management cannot be based only on BMI, a PA consultation on the top of the traditional pediatric and nutrition interventions may further improve the BMI z-score outcome at 6 months. What is Known: • Physical activity (PA) plays an important role in weight management. However, most adolescents, in particular those who are overweight, present low levels of PA. • There is no consensus whether PA counseling influences PA behavior. What is New: • A PA consultation (a structured form of PA counseling) as part of a multidisciplinary team may further be useful for weight management of overweight adolescents followed at the clinical setting, compared to the traditional approach including only the pediatric and nutrition consultations. • Waist-to-height ratio may be more suitable than waist circumference per se to track changes in abdominal adiposity among adolescents who are still growing.

Abstract
UNLABELLED Doxorubicin (DOX) is used in pediatric cancer treatment. This study assessed the effects of 7 weeks of DOX and 10-week recovery on bone quality and biomechanical properties in sedentary and exercised Wistar rats. DOX decreases femur diaphysis radial growth and biomechanical properties. Some of these DOX effects were aggravated by exercise. INTRODUCTION Bone growth in pre-pubertal years critically influences adult fracture risk. DOX is widely used in the treatment of pediatric cancers, but there is limited evidence on its potential negative effects on bone growth. Exercise improves bone growth in children, but there is no evidence if it protects against DOX-induced bone toxicity. This study investigates the early and intermediate effects of a 7-week course of DOX on bone histomorphometry and strength in sedentary and exercised growing animal models. METHODS Sixty-eight male Wistar rats (8 weeks) were treated with DOX (2 mg kg-1) or vehicle for 7 weeks and afterward housed in standard cages or in cages with a running wheel and killed 2 or 10 weeks after last DOX administration. Femurs and blood were collected for assaying geometry, trabecular microarchitecture (histology), biomechanical properties (three-point bending and shearing of the femoral neck), bone calcium content and density (atomic absorption spectroscopy), and bone turnover markers (ELISA). RESULTS DOX treatment reduced the femur diaphysis radial growth, with DOX-treated animals having a lower tissue area, cortical area, cortical thickness, and moment of inertia. DOX also decreased distal femur trabecular bone volume and trabecular number and increased trabecular separation. Femur diaphysis stiffness and maximum load were also reduced in past DOX-treated animals. Exercise was shown to worsen the effects of past DOX treatment on the femur diaphysis mechanical properties. CONCLUSION DOX negatively affects bone geometry, trabecular microarchitecture, and femur mechanical properties in growing Wistar rats. Exercise further aggravates the detrimental effects of past DOX treatment on bone mechanical properties.

Abstract
Objective Birth prevalence of Cobalamin (Cbl) C or D defects in Portugal is an estimated 1:85,000, one of the highest worldwide. We compared the genotype/phenotype of patients identified with CblC or CblD before and after the implementation of expanded newborn screening. Methods Twenty-five Portuguese CblC/D patients, 14 symptomatic and 11 identified through screening, were diagnosed using gas chromatography or tandem mass spectrometry. Molecular characterization was performed through the study of MMACHC and MMADHC genes. Results The most common MMACHC mutation, c.271dupA, was present in 100% of MMACHC alleles of all CblC screened patients, in contrast with the 61% identified before expanded newborn screening. All studied cases (except one, who presented a CblD deficiency) presented a CblC defect. More CblC late-onset patients were diagnosed before the introduction of newborn screening than in the post newborn screening era, probably because some early onset patients died without a definitive diagnosis. Conclusion The molecular data found in this cohort contribute to the improvement of screening and diagnosis of Cbl defects and would enable a confirmatory diagnosis of these patients, reducing the need for complex, costly, laborious, and time-consuming biochemical/enzymatic tests.

Abstract
Methionine adenosyltransferase deficiency (MAT I/III deficiency) is an inborn error of metabolism resulting in isolated hypermethioninemia, and usually inherited as an autosomal recessive trait, although a dominant form has been reported in several families.During the last 6 years, approximately 520,000 newborns were screened in the Portuguese Newborn Screening Laboratory by MS/MS, and 21 cases of persistent hypermethioninemia were found. One case was confirmed to be a deficiency of cystathionine β-synthase and 20 cases were confirmed by MAT1A gene analysis to have an elevation of methionine due to MAT I/III deficiency, which indicates an incidence for this condition of 1/26,000. Twelve of the MAT I/III deficient newborns, belonging to 11 families, were identified in the northern region of Portugal and sent to the same treatment center, where they are under follow-up. Clinical, biochemical, and genetic characteristics of individuals from these 11 families are presented. Plasma methionine and homocysteine concentrations were found to be moderately increased in all newborns, and molecular analysis revealed that they all were heterozygous for R264H mutation. Normal growth, development, and neurological examination were observed in all cases, and cerebral MRI performed in six cases revealed myelination abnormalities in one case. Plasma methionine concentration for all 12 cases was always below 300 μM, and they are all on a normal diet for their age.

Abstract
The aim of the present study was to analyze the lifelong differences of femur structure in sedentary and physically active animal models. Thirty male C57BL/6 mice, 2 months old, were either: i) housed in cages with running wheel (AA; n=10), ii) housed in cages without running wheel (AS; n=10), iii) or sacrificed without intervention (Y; n=10). AA and AS animals were sacrificed after 23 months of housing. Right femur structure was analyzed in all animals by histomorphometry. Significant differences in several microarchitectural parameters of cancellous and cortical bone were identified between Y mice and both groups of aged mice, as well as between AA and AS groups. Lifelong physically active mice had significantly higher cancellous bone surface (Cn.BS) and trabecular number (Tb.N) and decreased trabecular separation (Tb.Sp) at both epiphyses when compared to AS animals. No differences were observed between Y and AA groups regarding osteocyte number (N.Ot) despite its significant reduction in AS animals, suggesting that age alone was not a cause for decreases in N.Ot. Our results suggest that the reduced bone quality observed in the elderly is not only a consequence of age but also of lack of physical activity since sedentary behaviour significantly aggravated the degenerative age-related bone differences.

Abstract
BACKGROUND To analyse the associations between body mass index (BMI) and health-related behaviours among Portuguese adolescents based on the three waves of the Health Behaviour in School-aged Children (HBSC) survey conducted in Portugal. METHODS Data were derived from the three waves (1998, 2002 and 2006) of the World Health Organization collaborative cross-national survey HBSC, including 17, 024 public school students (6th, 8th and 10th grades). Separate analyses of the variables under study were individually conducted for each of the three waves of the survey, and for the total sample according to BMI (normal-weight and overweight/obese) using Chi square. At a second step, a multivariate logistic regression model was tested using all the variables that were significantly associated with normal or excess BMI values at a bivariate level, in order to determine whether they would predict being overweight, when controlling for all the others in the model. RESULTS Overweight adolescents reported their health as fair or poor more often, reported a poorer perception of academic achievement, were more likely than their peers to describe themselves as 'unhappy', and reported irritability or bad temper more often. According to our findings, being overweight can be predicted by being a male, being younger, having low body satisfaction, having a perception of poor academic achievement, of poor personal health and of being unhappy. Being overweight was not significantly predicted by the year of data collection. CONCLUSIONS Overweight adolescents were consistently far more likely to exhibit difficulties with their physical and emotional health when compared with their non-overweight peers. Although the effects of overweight on psychosocial functioning remain incompletely defined, they may constitute important determinants of overweight persistency, as well as have a detrimental effect on the adolescent's developmental process.

Abstract
AIM To assess in a subset of a nationally representative sample of Portuguese adolescents, the validity of Body Mass Index (BMI) based on self-reported weight and height. METHODS This study included 462 students in grades 6, 8 and 10 (mean age 14.0 +/- 1.9 years) from 12 public schools randomly selected from the list of schools which took part in the 2006 Health Behaviour in School Aged Children Portuguese survey, corresponding to approximately 10% of the sample. Self-reported weight and height were recorded and then measured. RESULTS Prevalence of normal weight, overweight and obesity based on self-report compared with that of measured values was not significantly different for boys and girls, and among age groups. BMI based on measured weight and height was underestimated compared with BMI based on self-reported data, both among girls and boys. Larger limits of agreement were found for boys, indicating a higher variability of self-reported BMI in estimating measured BMI, specifically below the age of 14 years. CONCLUSION These data suggest that BMI based on self-reported weight and height is not accurate for BMI prediction at an individual level. However, self-reported BMI may be used as a simple and valid tool for BMI estimates of overweight and obesity in epidemiological studies.

Abstract
OBJECTIVE To examine the emotional, behavioural and social correlates of missing values for body mass index (BMI) in a nationally representative sample of Portuguese youth. DESIGN AND METHODS 6131 Portuguese public school students aged 11-16 years in 6th, 8th and 10th grades who participated in the 2002 HBSC/WHO survey of adolescent health were included. Those not reporting their weight and/or height were compared with their peers. Bivariate analyses of psychosocial and behavioural variables were conducted to compare the two groups. Multivariate logistic regression was used to determine if variables significantly associated with missing values for BMI at a bivariate level predicted missing BMI when controlling for all other variables in the model. RESULTS Of 6131 adolescents answering the questionnaire, 661 (10.8%) did not report their weight and/or height. Gender was not associated with missing BMI. Missing values were significantly predicted by younger age (adjusted odds ratio (aOR) = 2.56, 95% CI 1.99 to 3.29, p<0.001), sedentary lifestyle (aOR = 1.53, 95% CI 1.16 to 2.01, p<0.01), poor body satisfaction (aOR = 1.34, 95% CI 1.19 to 1.51, p<0.001), absence of father (aOR = 1.62, 95% CI 1.14 to 2.30, p<0.01), lack of friends of the opposite sex (aOR = 1.65, 95% CI 1.03 to 2.66, p<0.05) and poor perception of academic achievement (aOR = 1.23, 95% CI 1.06 to 1.42, p<0.01). DISCUSSION Our findings suggest that those with missing values for BMI tend to have poorer body image, poorer health behaviours and poorer social networks. These results have implications for potential bias in the results of studies that do not account for missing BMI.

Abstract
OBJECTIVE To describe the prevalence of health risk behaviors and identify risk and protective factors that are associated with several health risk behaviors (cigarette smoking, drug use, onset of sexual intercourse before age 15, pregnancy, gun-carrying, suicidal ideation, and suicide attempts) among adolescents in Brazil, as well as to explore gender differences. METHODS We estimated prevalence rates, evaluated bivariate associations, and explored multivariate analyses using logistic regression on data from a 1997 survey of adolescent health among 2059 eighth- and 10(th)-grade students in Santos, Brazil. RESULTS Youth in Santos, Brazil report high rates of gun-carrying, suicidal thoughts and attempts, sexual intercourse, and pregnancy. Factors associated with diminished involvement for nearly all health risk behaviors, for both boys and girls, included having good family relationships, and feeling liked by friends and teachers. Factors associated with increases in nearly all health risk behaviors were: gun-carrying and gun availability in the home, drug use, and sexual abuse. CONCLUSIONS Factors that are associated with a wide range of health risk behaviors among adolescents in Brazil appear to parallel those found in industrialized countries: access to guns, substance use, and sexual abuse. Likewise, connectedness to family, school, and peers is consistently the protective factor associated with diminished risky behaviors.

Abstract
The results of the black light test for aflatoxin-contaminated maize carried out in a large food factory in the State of São Paulo was evaluated against bi-directional thin layer chromatography (TLC) analysis for 286 samples of maize. All 286 samples were accepted by the black light test (< 7 fluorescent points), however, the results from TLC analysis showed that 96 samples were contaminated and 14 showed aflatoxin B1 contamination levels higher than 20 micrograms/kg. There were 14 false negative results and no false positives and out of the 14 samples, six did not show visible fluorescent points. If the rejection criterion of one or more fluorescent points were applied, the six samples would be accepted by the black light test. But, in this case, 95 samples would be rejected and 87 results would be false positives because they did not have contamination levels over 20 micrograms/kg which is the acceptance limit of the black light test. The results indicate that the black light test, as utilized by this factory, was not able to indicate lots with possible contamination and the black light test, as recommended in the literature, would produce a high number of false positives. It is necessary to make more studies on the use of black light as a screening test for possible aflatoxin B1-contaminated maize.

Abstract
In the present work the influence of bag materials on the moisture loss and final aflatoxin content of stored moist in-shell peanuts (MIP) was studied in the rainy season of 1990, in Marília, São Paulo, and in the rainy season of 1991, in Jaboticabal, São Paulo. In each season, MIP were ventilated, as they arrived from the field, to get rid of extraneous materials and then put into 120 bags of jute and into 120 bags of polypropylene, and stored in stacks (12 bags base x 10 bags high). In the rainy season of 1990 (February-April) moisture and aflatoxin were determined at the beginning (average moisture = 14.31%; aflatoxin not detected). Subsequently, moisture was determined twice a week in samples taken from the external part of the stacks for 80 days, when the stacks were dismantled and moisture and aflatoxin were determined in six samples of each stack. In the rainy season of 1991 (February-March), because of operational difficulties, closed mesh jute bags were used (green coffee type) and the experiment lasted only 30 days. Moisture and aflatoxin were determined only at the beginning (average moisture = 15%; aflatoxin not detected). At the end of the storage period three samples were taken from each lot, for moisture and aflatoxin analyses.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
In the present work, the effect of propionic acid (ammonium salt) at 3000 mg/kg of unshelled peanuts (PA1) and at 5000 mg/kg (PA2), grapefruit seed extract at 5000 mg/kg (GF1) and 10,000 mg/kg (GF2), sodium orthophenylphenate at 2500 mg/kg (SOP1) and at 5000 mg/kg (SOP2) and thiabendazole at 1000 mg/kg (TBZ1) and at 5000 mg/kg (TBZ2) was studied for controlling total and potentially aflatoxigenic fungi in unshelled peanuts (UP). Samples of sound mature UP were moistened by adding water and kept refrigerated till they reached ca 16% moisture. The samples were then sprayed with the chemical solutions and incubated at 30 +/- 2 degrees C for 28 days. Control samples were sprayed with water. An evaluation of total and aflatoxigenic fungi was made, in pods of UP and in kernels obtained aseptically, before and at 7, 14, 21 and 28 days of incubation, by serial dilution in culture media Dichloran Rose Bengal Chloramphenicol (total fungi count) and in Aspergillus flavus parasiticus Agar (potentially aflatoxigenic count). In relation to the period and conditions of this experiment the overall best treatment was PA2, when the lowest average value of total and aflatoxigenic fungi were obtained in UP and were maintained in its kernels. Although SOP2 treatment could control fungal contamination in pods, it was not effective in controlling contamination through the kernels. The other treatments were ineffective.

Abstract
Propionic acid (ammonium salt) at 3000 mg/kg (PA1) and 5000 mg/kg (PA2) of unshelled peanuts (UP); grapefruit seed extract at 5000 mg/kg (GF1) and 10,000 mg/kg (GF2); sodium orthophenylphenate at 2500 mg/kg (SOP1) and 5000 mg/kg (SOP2); thiabendazole 1000 mg/kg (TBZ1) and 5000 mg/kg (TBZ2) were studied in the laboratory, to verify their efficiency in controlling fungal growth and aflatoxin (AF) production on moist UP (16-18% moisture content). Moist UP were put into polyethylene bags with cotton plugs and incubated at 30 +/- 2 degrees C for 28 days. Treatments were considered efficient when the AF content (B1 + G1) remained under 30 micrograms/kg. PA1 treatment was efficient till 14 days of incubation and PA2 during the whole incubation period (28 days). All other treatments were not efficient, showing AF contents from 150 to 108,333 micrograms/kg during the incubation periods. Propionic acid, used as ammonium propionate, at 5000 mg/kg shows promise in controlling aflatoxin production when applied to moist unshelled peanuts.

Abstract
This paper presents the deliberations and conclusions of an international group of health practitioners, researchers and planners who met in 1991 to explore risky behaviours and risk assessment in the context of the World Health Organization's strategy Health for All By 2000. A definition of risky behaviours is discussed and a method of exploring risk contexts, 'a risk equation', is presented. Lay risk assessment is explored and contrasted with professional perceptions of risk as evidenced in health education campaigns. It is concluded that the application of epidemiological techniques--the study of the incidence and prevalence of risk-related and health-related behaviours--employing qualitative methods provides a useful means of exploring the social and cultural context of risk behaviour.

Abstract
Este trabalho teve o escopo de dar a público os resultados das análises efetuadas num total de 625 amostras de amendoim descascado, na sua maioria HPS ("hand pick selected"), durante os anos de 1988 (517) e 1989 (108). Considerando que a legislação brasileira permite um máximo de 30 /¼g/kg, somadas as aflatoxinas B1 e G1, os resultados mostraram que em 1988, 52% das amostras (correspondentes a lotes), estavam contaminadas e em 1989, 34%. Os níveis médios de aflatoxina nas amostras contaminadas foram de 13 3,8 ¼g/kg em 1988 e 414,8 ¼g/kg em 1989, que podem ser considerados elevados. O contingente de lotes utilizáveis pela indústria foi de 67% em 1988 e 76% em 1989 (correspondentes às amostras com níveis não detectáveis e abaixo de 30 ¼g/kg).

Abstract
The retention of ascorbic acid, beta-carotene and sensory properties of freeze-dried red guava pulp stored during 18 months in hermetically sealed brown glass flasks, at room temperature (ca. 25 degrees C) was studied. The results showed that the losses during freeze-drying were of 8.13% for ascorbic acid and 0.63% for beta-carotene. During storage more pronounced losses of these elements occurred during the first six months, becoming progressively smaller and almost irrelevant at the end of the period. The sensory evaluation of the reconstituted pulp showed that the retention of flavor was good. A Gompertz curve was fitted to observe data and showed to be efficient in explaining the trend of reduction for both elements under study. The excellent retention of ascorbic acid, the relatively fair retention of beta-carotene during processing and storage of freeze-dried red guava pulp, and the good conservation of flavor of the reconstituted pulp are evidences of the importance of this process for preserving and storing fruit pulps.

Abstract
Seis tipos de óleos comestíveis (de milho, de soja, de oliva, de algodão, de amendoim e de girassol) e duas gorduras de origem animal (manteiga e banha) foram analisados quanto aos seus teores em ácidos graxos, por meio da cromatografia em fase gasosa. O óleo de girassol apresentou o maior teor de ácidos graxos insaturados (86,10%) seguido pelo óleo de soja 84,15% e sendo o óleo mais saturado, o de algodão (24,23%). A manteiga apresentou grande número de ácidos graxos, desde 4 até 22 átomos de carbono, apresentando 58,00% de saturados. A banha de porco apresentou 39,82% de ácidos graxos saturados. Os ácidos graxos mais abundantes foram o olêico e linoléico, entre os insaturados e palmítico, entre os saturados.

Abstract
Vinte e oito amostras de grãos de café verde, pertencentes à variedade Mundo Novo e separadas em quatro tipos de bebidas (MOLE, DURA, RIADA e RIO) foram analisadas quanto ao teor e propriedades do extrato etéreo e a composição do óleo, em ácidos graxos. O teor do extrato etéreo foi maior para os cafés de melhor bebida, porém houve diferença significativa apenas para os de bebida DURA. Não se constataram diferenças significativas no teor de ácidos graxos entre os quatro tipos de bebida. Quanto às propriedades químicas do extrato etéreo (índices de saponificação, acidez e iôdo) não houve diferença significativa. Concluiu-se que estes componentes e propriedades não podem ser utilizadas para a caracterização do tipo de bebida.
