The dyslipidemia and excess weight in adolescents, when combined, suggest a progression of risk factors for cardiovascular disease (CVD). Besides these, the dietary habits and lifestyle have also been considered unsuitable impacting the development of chronic diseases. The study objectives were: (1) estimate the prevalence of lipid profile and correlate with body mass index (BMI), waist circumference (WC) and waist / height ratio (WHR) in adolescents, considering the maturation sexual, (2) know the sources of variance in the diet and the number of days needed to estimate the usual diet of adolescents and (3) describe the dietary patterns and lifestyle of adolescents, family history of CVD and age correlates them with the patterns of risk for CVD, adjusted for sexual maturation. A cross-sectional study was performed with 432 adolescents, aged 10-19 years from public schools of the Natal city, Brazil. The dyslipidemias were evaluated considering the lipid profile, the index of I Castelli (TC / HDL) and II (LDL / HDL) and non-HDL cholesterol. Anthropometric indicators were BMI, WC and WHR. The intake of energy, nutrients including fiber, fatty acids and cholesterol was estimated from two 24-hour recalls (24HR). The variables of lipid profile, anthropometric and clinical data were used in the models of Pearson correlation and linear regression, considering the sexual maturation. The variance ratio of the diet was calculated from the component-person variance, determined by analysis of variance (ANOVA). The definition of the number of days to estimate the usual intake of each nutrient was obtained by taking the hypothetical correlation (r) ≥ 0.9, between nutrient intake and the true observed. We used the principal component analysis as a method of extracting factors that 129 accounted for the dependent variables and known cardiovascular risk obtained from the lipid profile, the index for Castelli I and II, non-HDL cholesterol, BMI, and WC the WHR. Dietary patterns and lifestyle were obtained from the independent variables, based on nutrients consumed and physical activity weekly. In the study of principal component analysis (PCA) was investigated associations between the patterns of cardiovascular risk factors in dietary patterns and lifestyle, age and positive family history of CVD, through bivariate and multiple logistic regression adjusted for sexual maturation. The low HDL-C dyslipidemia was most prevalent (50.5%) for adolescents. Significant correlations were observed between hypercholesterolemia and positive family history of CVD (r = 0.19, p <0.01) and hypertriglyceridemia with BMI (r = 0.30, p <0.01), with the CC (r = 0.32, p <0.01) and WHR (r = 0.33, p <0.01). The linear model constructed with sexual maturation, age and BMI explained about 1 to 10.4% of the variation in the lipid profile. The sources of variance between individuals were greater for all nutrients in both sexes. The reasons for variances were  1 for all nutrients were higher in females. The results suggest that to assess the diet of adolescents with greater precision, 2 days would be enough to R24h consumption of energy, carbohydrates, fiber, saturated and monounsaturated fatty acids. In contrast, 3 days would be recommended for protein, lipid, polyunsaturated fatty acids and cholesterol. Two cardiovascular risk factors as have been extracted in the ACP, referring to the dependent variables: the standard lipid profile (HDL-C and non-HDL cholesterol) and "standard anthropometric index (BMI, WC, WHR) with a power explaining 75% of the variance of the original data. The factors are representative of two independent variables led to dietary patterns, "pattern 130 western diet" and "pattern protein diet", and one on the lifestyle, "pattern energy balance". Together, these patterns provide an explanation power of 67%. Made adjustment for sexual maturation in males remained significant variables: the associations between puberty and be pattern anthropometric indicator (OR = 3.32, CI 1.34 to 8.17%), and between family history of CVD and the pattern lipid profile (OR = 2.62, CI 1.20 to 5.72%). In females adolescents, associations were identified between age after the first stage of puberty with anthropometric pattern (OR = 3.59, CI 1.58 to 8.17%) and lipid profile (OR = 0.33, CI 0.15 to 0.75%). Conclusions: The low HDL-C was the most prevalent dyslipidemia independent of sex and nutritional status of adolescents. Hypercholesterolemia was influenced by family history of CVD and sexual maturation, in turn, hypertriglyceridemia was closely associated with anthropometric indicators. The variance between the diets was greater for all nutrients. This fact reflected in a variance ratio less than 1 and consequently in a lower number of days requerid to estimate the usual diet of adolescents considering gender. The two dietary patterns were extracted and the pattern considered unhealthy lifestyle as healthy. The associations were found between the patterns of CVD risk with age and family history of CVD in the studied adolescents

Overweight and obesity are defined as abnormal or excessive fat accumulation that may impair health. Obesity significantly increases the risk of developing numerous medical conditions, besides is associated with shortened life span. The objective of this study was to evaluate the anthropometric measurements and lipid profile in adult overweight and obese subjects residents in the state of Rio Grande do Norte. The methodology was the analysis of certain biochemical parameters in serum of individuals and a physical evaluation that consisted of measurements of blood pressure and anthropometric data. In addition, the volunteers of the research answered a questionnaire about personal, social and clinical data. 1741 samples were collected, of which 432 (24,8%) were obese. Of these, 280 were selected to participate in the study, including 118 (42,1%) men and 162 (57,9%) women. Of the remaining 1309 individuals, 731 (55,8%) were overweight. Among them, 179 (24.5%) were analyzed in this study, with 56,4% female. Of the remaining 578 normal individuals, 143 were selected as controls in the research. Amid the obese, overweight and eutrophic, there were respectively 10% vs 5% vs 5,6% of diabetics, 92,1% vs 85,5% vs 68,7% of dyslipidemics and 38,6% vs 22,3% vs 15,6% of hypertensive patients. The degree of obesity presented by the participants was varied, with the majority (72,8%) fall into grade I obese, 22,9% (64) in grade II and only 4,3% (12) in grade III. Mean anthropometric participants showed statistically significant differences between groups eutrophic, overweight and obese on the BMI, WC, WHR and %BF and between sexes in CC, WHR and %BF. As the mean serum biochemical parameters to evaluate the lipid profile showed significant differences between groups eutrophic, overweight and obese, unless the exception of HDL among overweight and obese. The significance level was 5% (p <0.05)

Venous ulcers (VU) is a chronic injury of the lower extremities and because of its high incidence and recurrence implies long and complex treatments, damaging the quality of life (QOL) and self-esteem (SE) of the people. This study aimed to analyze the association between self-esteem with the quality of life of people with venous ulcers treated in primary care. Cross sectional analytical study with a quantitative approach conducted with 44 people met with VU at 13 primary care units 2 and Mixed units in Natal/RN. The study was approved by the Ethics Committee in Research of the Federal University of Rio Grande do Norte (UFRN), CAAE: 07556312.0.0000.5537. Held data collection from February to April 2014 and used three instruments: a structured form covering sociodemographic, health care and clinical variables, the Rosenberg Self-Esteem Scale and the SF-36. The collected data were entered into a database and processed on computerized software for descriptive and inferential analyzes. The results showed a predominance of people with UV females (65,9%), with more than 60 years (59,1%), married or in a stable relationship (52,3%), low education (86,4%) without occupation (68,2%) and less than one minimum wage income (81,8%). Regarding assistance characteristics was observed that most patients performed the dressing with appropriate material (72,7%), professional or trained caregiver (61,4%) did not use compression therapy (81,8%), treating the injury for more than 6 months (77,3%), lack of guidelines for the use of compression therapy, elevation of legs, and regular exercise (77,3%) and consulting the angiologist last year (52,3% ). Regarding clinical features of the lesion was found that most of the recurrent lesions are (77,3%), over one year of current lesion (52,3%) medium to large lesions (54,8%), without signs of infection (61,3%) and pain (79,5%). The mean SE of respondents was 9,3 (± 5,1). The relations between the SE and the sociodemographic variables, health care and clinics showed that individuals without a partner (a) (p = 0,01), who did not wear compression therapy (p = 0,04), with more 6 months of treatment (p = 0,01) and larger lesions (p = 0,01) had a lower SE. The mean domain and the dimensions of the SF-36 were lower emphasizing the functional capacity 36.5 (± 27,6) and the physical aspects of 15.3 (± 30,6). There were significant correlations between AE people with VU and the domains and dimensions of the SF-36: physical functioning (r = -0,432), general health (r = -0,415), vitality (r = -0,573), aspects social (r = -0,517), mental health (r = -0,612) and mental health dimensions (r = -0,612) and physical health (r = -0,473). Based on these results it is concluded by rejecting the null hypothesis and accept the alternative proposed in the study in which it was found that there is a negative correlation between the SE and the QOL of people with venous ulcers

Esse estudo se propôs a avaliar um método auxiliar de diagnóstico (DIAGNOdent®) na predição de cárie de dentina em dentes decíduos, através de validação histológica e de microdureza. Verificando possíveis diferenças entre os valores obtidos através do método auxiliar, além de determinar um ponto de corte para parada de remoção de tecido cariado. A amostra do estudo foi de 15 crianças que apresentaram 21 cavidades de cárie, tratadas e analisadas desde antes da realização da restauração até quando da exodontia do elemento dentário. Os espécimes foram analisados através do DIAGNOdent® antes da abertura das cavidades, após a remoção do tecido cariado e depois da reabertura das cavidades que se deu após a exodontia dos elementos dentários. Posteriormente, receberam preparo metalográfico para realização de testes de microdureza e microscopia óptica que serviram como forma de validação para as mensurações obtidas pela fluorescência a laser. Houve diferença significativa entre os valores DIAGNOdent® encontrados antes da abertura da cavidade e os demais (p < 0,0001). Havendo correlação significativa (r = 0,432 ; p = 0,019) apenas para as aferições obtidas antes da abertura das cavidades e quando do término da remoção do tecido cariado. Para a microdureza, as médias axiais foram significativamente maiores que as pulpares, existindo correlação entre a microdureza pulpar e os valores do DIAGNOdent® após a reabertura (r = - 0,472 ; p = 0,002). Valores de 15,38% para a sensibilidade, 100% para a especificidade, 100% para o valor preditivo positivo e 71,79% para o valor preditivo negativo, foram obtidos quando se utilizou um ponto de corte de 30 para fluorescência a laser, tendo como padrão-ouro a microdureza pulpar. Partindo da média dos valores de fluorescência a laser obtidos após a remoção do tecido cariado e acrescentando-se um desvio-padrão a esta, o método indicou o valor de 19 como ponto de corte para cessar a remoção de dentina. Concluiu-se que, nas condições analisadas, o método auxiliar de diagnóstico (DIAGNOdent®) é um método acurado na predição de cárie de dentina em dentes decíduos. Além disso, o método comprovou que o padrão usual de remoção de dentina garante a remoção do tecido cariado

The process of salting and drying in the sun is used to preserve meat since the beginning of civilization. There is evidence that this preservation technique has arisen in Egypt, between 4,000 and 5,000 years ago. In our country, according to literature, was the first industrial product that gave the appearance of beef jerky, beef being produced, where about 70% to 75% of the muscle is composed of water, where it will be around 45% as a final product, according to the law in his article RIISPOA No. 432 provides that the jerky should contain no more than this amount of moisture in the muscular portion, or more than 15% of total ash with tolerance of up to 5% variation . Besides this parameter, proteins, lipids, ash, and minerals were analyzed in samples before and after the manufacturing process to know the content of these nutrients. Since these are considered important in product quality, thus the concentration in these samples, respectively, in the flesh Front (CD and CHD) before and after the manufacturing process for humidity were respectively 75.28% and 47.38% , the protein was 14.17 and 22.20 g / 100 g sample, 6.360 and 4.251 of lipids g/100g of the sample, and the ashes 0.974 9.144 g/100g sample, minerals like calcium and 4.074 30 , 06 ppm, sódio0, 055 and 5.401 g / L, sodium chloride, 0.139 and 13.74 g / L, potassium 237.5 and 166.8 ppm, 1.721 and 3.295 ppm iron, 0.143 and 0.135 ppm phosphorus, zinc and 4.690 6.905 ppm; magnésio14, 63 e13, 75 ppm manganese .017 e0, 007ppm, copper 0.057 and 0.039 ppm in the case of needle-type meat (CPA and CHPA), 68.04% and 44.17%, protein 13 , 72, and 24.42 g/100g of sample, 1.137 in the ash and 12.68 g / 100g of sample, and the minerals calcium 17.11 and 12.89 ppm; sódio0, 123 and 4.871 g / L, sodium chloride 0.312 and 12.39 g / L, potassium 305.3 and 182.1 ppm; ferro1, 817 and 1.513 ppm, 0.273 and 0.139 ppm phosphorus, zinc 6.305 and 4.783 ppm, 27.95 and 15.85 ppm magnesium, manganese and 0.025 0.011 ppm, 0.057 and 0.143 ppm copper and chromium 0.014 and 0.068 ppm
