The article "Body Mass Index as an Indicator of Survival in Oral Cancer" published in Oral Diseases discusses the significance of body mass index (BMI) as a prognostic factor for patients with oral squamous cell carcinoma (OSCC). A retrospective cohort study was conducted, showing that patients with a higher BMI at diagnosis had better overall survival (OS) and disease-specific survival (DSS). However, the protective effect of being overweight diminishes when BMI exceeds 30 kg/m2 due to an increased risk of developing other diseases. The study suggests that assessing BMI at diagnosis may help identify more vulnerable patients with OSCC. [Extracted from the article]

Objectives: Few studies have investigated the influence of polyunsaturated fatty acid consumption on excessive weight gain during pregnancy. Thus, we analyzed the association between the intake of polyunsaturated fatty acids (ω‐6 and ω‐3) and weight gain in women during pregnancy. Methods: This is a cohort study of 250 pregnant women enrolled in municipal pre‐natal services. Weight, height, and dietary intake of polyunsaturated fatty acids were evaluated at the baseline. The semi‐quantitative food frequency questionnaire was employed to assess the main exposure. Gestational weight was measured in the first, second, and third trimesters. A dietary pattern involving the consumption of fatty acids was identified through factor analysis. A generalized estimating equation was used for the data analysis. Results: The prevalence of excessive weight gain at the end of pregnancy was 35.2%. Consumption patterns 1 (salted meats, offal, vegetable oil, snacks, legumes, and oleaginous foods) and 2 (red meat, sausages, butter, margarine, mayonnaise, acarajé, caruru, vatapá, and refined cereals) revealed a risk for the accumulation of excess weight during pregnancy. Women who adhered to consumption patterns 1 (RR: 2.39; 95% CI: 1.44–3.94) and 2 (RR: 2.39; 95% CI: 1.44–3.94) were more susceptible to excess weight gain during pregnancy. Conclusions: Women who adhered to dietary patterns involving foods that are sources of ω‐6 fatty acids and saturated fatty acids were more susceptible to gaining weight during pregnancy compared to those who adhered less to these patterns.

VITAMIN D deficiency ,META-analysis ,VITAMIN D ,AGE groups ,EPIDEMIOLOGY ,POPULATION - Abstract
Studies conducted among populations of tropical countries have reported high prevalences of vitamin D deficiency and insufficiency. Information resulting from meta-analyses on the spatial distribution of vitamin D deficiency and insufficiency in tropical countries is still rare. The aim of this review was investigated the prevalence of vitamin D deficiency and insufficiency among the Brazilian population. Observational studies were searched in eight electronically databases. Additionally, theses and dissertations and abstracts were screened. Details on study design, methods, population, mean and data on serum concentrations of vitamin D in different age groups in Brazil were extracted. Data were pooled using a random-effects model and choropleth maps were created based on the geopolitical regions of the country. 72 published paper met the inclusion criteria. The mean vitamin D concentration among the Brazilian population between 2000 and 2017 of 67.65 nmol/L (95% CI: 65.91, 69.38 nmol/L).The prevalences of vitamin D deficiency and insufficiency were 28.16% (95% CI: 23.90, 32.40) and 45.26% (95% CI: 35.82, 54.71), respectively, for the Brazilian population. The highest prevalence of deficiency were observed in the southern and southeastern regions and the highest occurrence of vitamin D insufficiency was among the populations of the southeastern and northeastern regions. Finally, there are high prevalence of inadequate vitamin D concentrations among the population, regardless of age group in Brazil. The development of vitamin D food fortification policies in needs to be cautious and carefully planned. [ABSTRACT FROM AUTHOR]

Adolescent ,Obesity ,Body weight changes ,Body composition ,Adiposity - Abstract
Adolescents with excess body fat and eutrophic had the same metabolic changes expected in obese individuals. To evaluate body composition, anthropometric changes, biochemical and clinical characteristics of female adolescents. A total of 113 adolescents from public schools in Viçosa, MG, divided into three groups: group 1 - consisting of eutrophic adolescents with excess body fat; group 2 - eutrophic with body fat within normal limits; and group 3 - with excess weight and body fat. Weight, height, waist and hip circumference, blood pressure were measured. The body mass index (BMI) and waist-hip ratio were calculated. The percentage of body fat was obtained by bioelectrical impedance horizontally, following its own protocol for this evaluation. The assessment of the percentage of body fat and biochemistry was performed after 12 hours of fasting, and analyzed the lipid profile, blood glucose and insulin, homocysteine, leptin and C-reactive protein. Insulin resistance was calculated by HOMA index. The group of eutrophic adolescents, with higher adiposity, behaved in relation to blood pressure, HDL and glucose levels, similarly to adolescents who are overweight. It can be seen that the HOMA index, insulin and leptin increased with increasing body fat. More than half of adolescents had total cholesterol and CRP levels above recommended levels. The most obvious metabolic disorder related to the lipid profile for both groups studied. Excess adiposity in normal weight adolescents may be related to clinical and biochemical changes similar to those found in adolescents who are overweight.

Adolescent ,Metabolic syndrome X ,Diagnosis ,Waist circumference ,Obesity - Abstract
To evaluate the diagnostic validity of four waist circumference reference tables in female adolescents for detection of lipid abnormalities, hyperinsulinemia, high homeostasis model assessment (HOMA), hyperleptinemia, and high body adiposity. We evaluated 113 adolescents aged between 14 and 19 years enrolled in public schools of Viçosa (state of Minas Gerais, Brazil). Total cholesterol, LDL, HDL, triglycerides, insulin and leptin levels were measured. We also measured the percentage of body fat using tetrapolar bioelectrical impedance. Based on the measure of the smallest abdominal diameter, we defined the waist circumference and calculated sensitivity, specificity, positive and negative predictive values. Contingency tables for the classification of waist circumference in adolescents were developed for four criteria: Freedman et al., 1999; Taylor et al., 2000; McCarthy et al., 2001; and Moreno et al., 2007. Sensitivity values were generally low in the reference studies evaluated, and the highest values were found in the reference table by McCarthy et al. On the other hand, specificity values were high, especially for the table by Freedman et al. Positive predictive values were more relevant for total cholesterol and body fat percentage. The cutoff points for waist circumference provided by McCarthy et al. proved to be the most suitable for population studies. Because it has higher specificity, the proposal by Freedman et al. is useful for clinical use and can replace high cost tests, which are often unavailable for health professionals, such as those to measure leptin and insulin levels.

OBJETIVO: Avaliar a validade diagnóstica de quatro tabelas de referência para circunferência da cintura em adolescentes do sexo feminino para detecção de alterações lipídicas, hiperinsulinemia, homeostasis model assessment (HOMA) elevado, hiperleptinemia e elevada adiposidade corporal. MÉTODOS: Avaliadas 113 adolescentes com idade entre 14 e 19 anos, provenientes de escolas públicas de Viçosa (MG). Em amostras de sangue foram dosados colesterol total, LDL, HDL, triglicerídeos, insulina e leptina. Determinado percentual de gordura corporal através de bioimpedância elétrica tetrapolar. Pela medida de menor diâmetro abdominal foi determinada a circunferência da cintura do abdômen e calculados valores de sensibilidade, especificidade, valor preditivo positivo e negativo. Foram elaboradas tabelas de contingência de classificação de circunferência da cintura em adolescentes para quatro critérios: Freedman et al., 1999; Taylor et al., 2000; McCarthy et al., 2001; e Moreno et al., 2007. RESULTADOS: Valores de sensibilidade em geral foram baixos para as referências avaliadas, sendo os maiores obtidos para a de McCarthy et al. Ao contrário, as especificidades foram altas, principalmente para a tabela de Freedman et al. Os valores preditivos positivos foram mais relevantes para colesterol total e percentual de gordura corporal. CONCLUSÃO: Os pontos de corte para circunferência da cintura de McCarthy et al. demonstraram-se os mais adequados para avaliações populacionais. A proposta de Freedman et al. por apresentar maior especificidade, é útil para uso clínico e pode substituir a realização de exames de custo elevado que em muitos locais não se encontram ao alcance dos profissionais de saúde, como leptina e insulina. OBJECTIVE: Assess diagnostic validity of four reference tables for waist circumference in female teenagers in order to detect lipid alterations, hyperinsulin, elevated homeostasis model assessment (HOMA), hyperleptinemia and excess of body adiposity. METHODS: A total of 133 female subjects, ranging from 14 to 19 years opf age , were evaluated. All adolescents were recruited from public schools in Viçosa/MG. Blood samples were collected for determination of fasting plasma cholesterol total, LDL, HDL, triglycerides, insulin and leptin. Percentage of body fat was determined through tetrapolar electrical bioimpedance. Using the smallest abdominal measure it was possible to determine waist circumference and calculated values of sensibility, specificity, positive and negative predictive values. Waist circumference contingency tables were obtained using four criteria: Freedman et al., 1999; Taylor et al., 2000; McCarthy et al., 2001; e Moreno et al., 2007. RESULTS: In general, sensibility values were low for circumferences assessed and the highest values were obtained for the table of Mc Carthy et al., on the other hand, specificity values were high considering the table of Freedman et al. The positive predictive values were more relevant for total cholesterol and body fat percentage. CONCLUSION: Cutoffs for waist circumference used by Mc Carthy et al. were the most appropriate for populational assessments. Freedman's et al. proposal is appropriate for clinical use since it presents higher specificity. In addition, it can substitute high costs exams, out of the professionals' reach such as insulin and leptin.

Fundação de Amparo a Pesquisa do Estado de Minas Gerais The subclinical chronic inflammation is confirmed as a new syndrome related to the development of insulin resistance. The fat tissue appears as important organ responsible for the increased expression of inflammatory substances, contributing to the development of this syndrome. This condition in adolescents with excess body fat is little known. The aim of this study was to evaluate the inflammatory profile of adolescents in overweight female post-pubescent, in those metabolic obese normal weight adolescents resistant to insulin. It was also a goal to verify the relationship between peripheral expression of mediators TNF-alpha, IL-6 and IL-10 and the parameters related to metabolic syndrome. 72 female adolescents in post-pubescent were evaluated, 14 to 17 years old. They were divided into 3 groups: eutrophic (G1), metabolic obese normal weight (G2) and overweight (G3). Data related to the parameters of the metabolic syndrome were collected: waist circumference, fasting plasma glucose, fasting insulin, insulin resistance, triglycerides, HDL, systolic and diastolic blood pressure. After the measurement of biochemical parameters, 10 overweight adolescents which were not insulin resistant were selected and those formed the control group (Si), and 10 overweight adolescents with insulin resistance were also chosen (Ri). It was evaluated the expression of mediators TNF-alpha, IL-6 and IL-10 in groups of study, and the correlation of these cytokines with the parameters of the metabolic syndrome. It was observed that G2 had intermediary values of weight, IMC and %GC in comparison to G1 and G3. Glicemia and insulin resistance were increased in G2 in comparison to G1, not differing of the G3. Insulinemia was increased and HDL was decreased in G2 in comparison to G3. Evaluating the peripheral expression of citocinas of G2 and G3 in comparison to G1, G3 had increase of 6% and 31% in expression of TNF-α and IL-10, respectively, and G2 had increase of 44% in expression of IL-6, without differences in the expression of cytokines between G2 and G3. There was positive correlation between TNF-α and IL-6, and between IL-10 and pro-inflammatory cytokines in the adolescents of G2, and in the adolescents with excess of body fat (G2 + G3), and positive correlation between IL-6 and glicemia (G2 group), and between IL-6 and triglycerides (G3 group). Considering overweight adolescents, there was no difference in the expression of cytokines evaluated among Si and Ri groups, although peripheric expression of IL-10 in the Ri group was 370% larger, regarding the Si group. In the adolescents of the Si group, IL-6 was positively correlated with IL-10, and negatively with insulinemia. IL-10 was negatively correlated with fast glicemia in the Si group. In the Ri group, there was no correlation between expression of cytokines and the parameters related with the metabolic syndrome. In the present study, Metabolic obese normal weight adolescents had metabolic profile, inflammatory profile and body composition similar to adolescents with overweight. It demonstrated the possible relation between IL-6 and glicemia and triglycerides. The positive correlations between IL-10 and TNF-α, IL-10 and IL-6, as well as the increased expression of IL-10 in overweigh adolescents regarding the eutrophic, suggests an attempt to inhibition the production of these citocinas by IL-10. Overweight adolescents with insulin resistance had similar peripehric expression to those overweight adolescents without insulin resistance. The increase of IL-10, and their negative correlation with fast glicêmica, can indicate possible protective paper of this cytokine in the development of cardiovascular risk factors. A inflamação crônica subclínica se configura como nova síndrome relacionada com o desenvolvimento da resistência insulínica. O tecido adiposo aparece como importante órgão responsável pelo aumento da expressão de substâncias inflamatórias, contribuindo para o desenvolvimento desta síndrome. Pouco se sabe sobre essa condição em adolescentes com excesso de gordura corporal. O objetivo este estudo foi avaliar o perfil inflamatório de adolescentes do gênero feminino póspúberes com sobrepeso e nas metabolicamente obesas de peso normal , e de adolescentes com sobrepeso resistentes à insulina. Também foi intuito verificar a relação entre a expressão periférica dos mediadores TNF-α, IL-6 e IL-10 e os parâmetros relacionados com a síndrome metabólica. Foram avaliadas 72 adolescentes do gênero feminino pós-púberes, de 14 a 17 anos de idade, divididas em 3 grupos: eutróficas (G1), metabolicamente obesas de peso normal (G2) e sobrepeso (G3). Coletaram-se dados relacionados aos parâmetros da síndrome metabólica: circunferência da cintura, glicemia de jejum, insulinemia de jejum, resistência insulínica, triglicerídeos, HDL, pressão arterial sistólica e diastólica. Após a aferição dos parâmetros bioquímicos, do grupo de adolescentes com sobrepeso foram selecionadas 10 adolescentes sem resistência insulínica, as quais constituíam o grupo controle (Si), e 10 adolescentes com resistência insulínica (Ri). Avaliou-se a expressão dos mediadores TNF-α, IL-6 e IL-10 nos grupos de estudo, e a correlação desses mediadores com os parâmetros da síndrome metabólica. Foi possível constatar que G2 apresentou valores intermediários de peso, IMC e %GC em comparação com G1 e G3. Maiores valores de glicemia e de resistência insulínica foram verificados no G2 em relação ao G1, não diferindo do G3. G2 apresentou maiores valores de insulinemia e menores de HDL que G3. Avaliando-se a expressão periférica das citocinas do G2 e G3 em relação ao G1, G3 apresentou aumento na expressão de TNF-α e IL-10 de 6% e 31%, respectivamente, e o G2 apresentou aumento de 44% na expressão de IL-6, não havendo diferenças na expressão das citocinas entre G2 e G3. Verificou-se correlação positiva entre TNF-α e IL-6, e entre IL-10 e as citocinas pró-inflamatórias nas adolescentes do G2, e nas adolescentes com excesso de gordura corporal (G2 + G3), e correlação positiva entre a IL-6 e glicemia (grupo G2), e entre IL-6 e triglicerídeos (grupo G3). Em relação às adolescentes com sobrepeso, não houve diferença na expressão das citocinas avaliadas entre os grupos Si e Ri, embora a expressão periférica de IL-10 no grupo Ri tenha apresentado-se 370% maior, em relação ao grupo Si. Nas adolescentes do grupo Si, IL-6 correlacionou-se positivamente com IL-10, e negativamente com a insulinemia. IL-10 correlacionouse negativamente com glicemia de jejum no grupo Si. No grupo Ri, não houve correlação entre a expressão de citocinas e os parâmetros relacionados com a síndrome metabólica. No presente estudo, adolescentes metabolicamente obesas de peso normal apresentaram perfil metabólico, inflamatório e de composição corporal semelhante à de adolescentes com sobrepeso. Demonstrou-se possível relação entre IL-6 e glicemia e triglicerídeos. A correlação positiva entre IL-10 e TNF-α e IL- 6, bem como a maior expressão de IL-10 nas adolescentes com sobrepeso em relação às eutróficas, sugere tentativa de inibição da produção dessas citocinas pela IL-10. Nas adolescentes com sobrepeso, aquelas resistentes à insulina apresentaram expressão periférica dos marcadores inflamatórios semelhante àquelas com excesso de peso sem resistência insulínica. O aumento da IL-10, e sua correlação negativa com a glicemia de jejum, indica possível papel protetor desta citocina no desenvolvimento de fatores de risco cardiovasculares.

As doenças cardiovasculares são consideradas um grande problema de saúde pública, uma vez que são a principal causa de morte no Brasil e no mundo. Essas doenças possuem etiologia multifatorial. Além da susceptibilidade genética, outros fatores, tais como idade e presença de hipertensão arterial, dislipidemias, obesidade, diabetes mellitus, inatividade física e alguns hábitos alimentares inadequados, são considerados importantes fatores de risco para o desenvolvimento de doenças cardiovasculares. O elevado consumo de carboidratos tem sido associado ao aumento da obesidade, às dislipidemias, à intolerância à glicose/diabetes mellitus e à resistência insulínica, estando, dessa forma, entre os fatores de risco das doenças cardiovasculares. Entretanto, existem controvérsias acerca da influência da qualidade do carboidrato ingerido no desenvolvimento de tais doenças, independentemente da quantidade ingerida. O índice glicêmico é um indicador da qualidade do carboidrato ingerido. Sua utilidade em condições de vida livre tem sido questionada, devido à interferência de vários fatores, os quais são difíceis de serem controlados sob tais condições. Este trabalho objetivou analisar criticamente os estudos que avaliaram o efeito do índice glicêmico dos alimentos na manifestação de doenças cardiovasculares e seus fatores de risco. Cardiovascular diseases are considered a great public health problem since they are the main cause of death in Brazil and in the world. These diseases have a multifactorial etiology. Besides genetic susceptibility, other factors such as age, hypertension, dyslipidemia, obesity, diabetes mellitus, physical inactivity and some inadequate dietary habits are considered important risk factors for the development of cardiovascular diseases. However, there are several controversies concerning how the quality of the ingested carbohydrate influences the development of such diseases, regardless of amount. The glycemic index is an indicator of carbohydrate quality. Its use in free living conditions has been questioned, due to the interference of several factors which are difficult to control under such conditions. The aim of this paper was to critically analyze studies that evaluated the effect of the glycemic index of foods in the manifestation of cardiovascular diseases and its risk factors.

- Abstract
Lower concentrations of omega-3 (ω-3) and higher concentrations of omega-6 (ω-6) have been associated with excess weight in adults; however, the information on this relationship in pregnancy remains in its infancy. This study aimed to investigate the association between plasma levels of ω-3 and ω-6 long-chain polyunsaturated fatty acids (PUFAs) and weight gain during the gestational period. This is a prospective cohort study involving 185 pregnant women registered with the prenatal services of a municipality in the northeast of Brazil. The dosage of the serum concentration of fatty acids and the anthropometric measurements were carried out at the baseline, and the women's weight information in the first, second, and third trimesters was collected from their pregnancy cards. Serum fatty acids were determined with the help of gas chromatography. The response variable of this study is the latent variable weight gain in pregnancy, derived from three variables: gestational weight in the first, second, and third trimesters. The main exposure was the plasma concentrations of PUFAs. Structural equation modeling was used for the data analysis. The mean age of the pregnant women was 26.74 years old (SD: 5.96 years). Most of the women had not completed high school (84%) and had a low income (70.86%). It was observed that the ω-3 PUFAs, represented by ALA plasm (alpha-linolenic acid), DHA (docosahexaenoic acid), and the EPA/ALA ratio (eicosapentaenoic acid to alpha-linolenic acid ratio), were negatively associated with the weight gain during pregnancy construct (−0.20, −0.12, and −0.14, respectively). Meanwhile, the PUFAs represented by the ratio between the ω-6 category acids ARA and LA (arachidonic acid and linoleic acid) had a direct and positive association (0.22) with that construct. Excess maternal weight gain was associated with ω-3 and ω-6 plasma levels. The women with the greatest gestational weight gain were the ones that presented the highest ARA/LA ratio (ω-6) and the lowest plasma concentrations of ALA, DHA, and EPA/ALA ratio (ω-3).

The dosage of the serum concentration of fatty acids and the anthropometric measurements were carried out at the baseline, and the women's weight information in the first, second, and third trimesters was collected from their pregnancy cards. Serum fatty acids were determined with the help of gas chromatography. The response variable of this study is the latent variable weight gain in pregnancy, derived from three variables: gestational weight in the first, second, and third trimesters. The main exposure was the plasma concentrations of PUFAs. Structural equation modeling was used for the data analysis. The mean age of the pregnant women was 26.74 years old (SD: 5.96 years). Most of the women had not completed high school (84%) and had a low income (70.86%). It was observed that the ω-3 PUFAs, represented by ALA plasm (alpha-linolenic acid), DHA (docosahexaenoic acid), and the EPA/ALA ratio (eicosapentaenoic acid to alpha-linolenic acid ratio), were negatively associated with the weight gain during pregnancy construct (-0.20, -0.12, and -0.14, respectively). Meanwhile, the PUFAs represented by the ratio between the ω-6 category acids ARA and LA (arachidonic acid and linoleic acid) had a direct and positive association (0.22) with that construct. Excess maternal weight gain was associated with ω-3 and ω-6 plasma levels. The women with the greatest gestational weight gain were the ones that presented the highest ARA/LA ratio (ω-6) and the lowest plasma concentrations of ALA, DHA, and EPA/ALA ratio (ω-3).

- Abstract
Objective: Assess diagnostic validity of four reference tables for waist circumference in female teenagers in order to detect lipid alterations, hyperinsulin, elevated homeostasis model assessment (HOMA), hyperleptinemia and excess of body adiposity., Methods: A total of 133 female subjects, ranging from 14 to 19 years of age , were evaluated. All adolescents were recruited from public schools in Viçosa/MG. Blood samples were collected for determination of fasting plasma cholesterol total, LDL, HDL, triglycerides, insulin and leptin. Percentage of body fat was determined through tetrapolar electrical bioimpedance. Using the smallest abdominal measure it was possible to determine waist circumference and calculated values of sensibility, specificity, positive and negative predictive values. Waist circumference contingency tables were obtained using four criteria: Freedman et al., 1999; Taylor et al., 2000; McCarthy et al., 2001; and Moreno et al., 2007., Results: In general, sensibility values were low for circumferences assessed and the highest values were obtained for the table of McCarthy et al., on the other hand, specificity values were high considering the table of Freedman et al. The positive predictive values were more relevant for total cholesterol and body fat percentage., Conclusion: Cutoffs for waist circumference used by McCarthy et al. were the most appropriate for populational assessments. Freedman's et al. proposal is appropriate for clinical use since it presents higher specificity. In addition, it can substitute high costs exams, out of the professionals' reach such as insulin and leptin.

- Abstract
Background: adolescents with excess body fat and eutrophic had the same metabolic changes expected in obese individuals., Objective: to evaluate body composition, anthropometric changes, biochemical and clinical characteristics of female adolescents., Methods: a total of 113 adolescents from public schools in Viçosa, MG, divided into three groups: group 1 - consisting of eutrophic adolescents with excess body fat; group 2 - eutrophic with body fat within normal limits; and group 3 - with excess weight and body fat. Weight, height, waist and hip circumference, blood pressure were measured. The body mass index (BMI) and waist-hip ratio were calculated. The percentage of body fat was obtained by bioelectrical impedance horizontally, following its own protocol for this evaluation. The assessment of the percentage of body fat and biochemistry was performed after 12 hours of fasting, and analyzed the lipid profile, blood glucose and insulin, homocysteine, leptin and C-reactive protein. Insulin resistance was calculated by HOMA index., Results: the group of eutrophic adolescents, with higher adiposity, behaved in relation to blood pressure, HDL and glucose levels, similarly to adolescents who are overweight. It can be seen that the HOMA index, insulin and leptin increased with increasing body fat. More than half of adolescents had total cholesterol and CRP levels above recommended levels. The most obvious metabolic disorder related to the lipid profile for both groups studied., Conclusion: excess adiposity in normal weight adolescents may be related to clinical and biochemical changes similar to those found in adolescents who are overweight.
