ABSTRACT

Objetivo: Investigar a relação entre o perfil de adesão e barreiras percebidas por estudantes universitários para permanência no Programa de Extensão "Yoga: Awaken ONE". Métodos: Foram realizados dois cortes transversais com universitários da Universidade Federal do Recôncavo da Bahia. O primeiro foi composto por 16 indivíduos e investigou o perfil demográfico, socioeconômico, antropométrico, da aptidão física e da qualidade de vida dos universitários que ingressaram no Programa de Extensão. O segundo visou identificar as barreiras para permanência de 13 estudantes (dentre os 16 iniciais) que haviam se afastado do Programa após quatro meses do início. Resultados: Houve predominância de indivíduos do sexo feminino, dos cursos de graduação em Educação Física e Pedagogia e da classe socioeconômica C. A maioria dos participantes estava com indicadores adequados de gordura corporal. Observou-se grande proporção de indivíduos com indicadores baixos de flexibilidade e força muscular. Para a qualidade de vida, a menor mediana foi observada para o domínio meio ambiente e a maior para o domínio relações sociais. As principais barreiras percebidas para a prática de yoga pelos universitários foram "jornada de estudos extensa" e "jornada de trabalho extensa". Observou-se correlação do perfil sociodemográfico, indicadores de obesidade, variáveis hemodinâmicas, flexibilidade, força muscular e qualidade de vida com barreiras percebidas para permanência no Programa de Extensão universitária "Yoga: Awaken ONE". Conclusões: Estes achados sugerem que o perfil do público universitário pode ser determinante para a permanência ou evasão de programas de promoção de exercícios físicos e precisa ser considerado em propostas de programas de extensão universitária.


Objective: Investigate the relationship between the member adherence profile and barriers perceived by university students to remain in the "Yoga: Awaken ONE" Extension Program. Methods: Two cross-sections were carried out with university students from the Federal University of Recôncavo da Bahia. The first was composed of 16 individuals and investigated the demographic, socioeconomic, anthropometric, physical fitness, and quality of life profile of university students joining the Extension Program. The second aimed at identifying the barriers to remain in the program faced by 13 students (out of the initial 16) who had withdrawn from the Program four months after the beginning. Results: There was a predominance of female individuals, from undergraduate courses in Physical Education and Pedagogy, and from the C socioeconomic class. Most participants had adequate body fat indexes. There was a large proportion of individuals with low flexibility and muscle strength. For quality of life, the lowest median was observed for the environment domain, while the highest could be noted for the social relationship domain. The main barriers perceived for the practice of yoga by university students were "long study hours" and "long work hours". There was a correlation between sociodemographic profile, obesity indicators, hemodynamic variables, flexibility, muscle strength, and QOL with the perceived barriers to stay in the "Yoga: Awaken ONE" university extension program. Conclusions: These findings suggest that the profile of the university audience can be a determinant for the permanence or dropout of programs that promote physical exercise and therefore, it should be taken into consideration in proposals for university extension programs.

ABSTRACT

En la Republica Argentina, la prevalencia de obesidad se ha incrementado considerablemente y la de diabetes mellitus tipo 2 (DMT2) alcanza 12,7%. La obesidad presenta heterogeneidad y el aumento de la grasa abdominal puede incluir hipertrigliceridemia, hiperglucemia, disminucion de C-HDL, aumentos de apolipoproteina B (Apo B), aumento de lipoproteinas LDL pequenas y densas, hiperinsulinemia, insulino-resistencia (IR), estado inflamatorio cronico, estado protrombotico y otras alteraciones metabolicas, que se han reunido en el llamado sindrome metabolico con prevalencia del 20 al 40%. La resistencia a la insulina (IR) esta presente en 10 al 25% de la poblacion y se asocia con esas alteraciones. La determinacion de IR es compleja, necesita de internacion en clinicas y debe ser realizada por especialistas. En el laboratorio se puede estimar a traves del dosaje de insulina, pero no esta estandarizado, por lo que es necesario disponer de tecnicas sencillas y accesibles. La relacion trigliceridos (TG)/colesterol HDL (C-HDL) puede ser una opcion utilizando como valores de corte TG/C-HDL ≥2,5 en mujeres y ≥3,5 en varones. Se asocia significativamente con IR y enfermedad cardiovascular (ECV), tiene buena especificidad aunque bajo poder discriminador por lo cual cuando esta presente y existe riesgo de DMT2 o ECV deberia complementarse con el calculo del colesterol-no-HDL o Apo B y el colesterol remanente. Teniendo en cuenta la pandemia de obesidad y DMT2 y la elevada frecuencia de ECV, la relacion TG/C-HDL podria ser un marcador que deberia ser informado por el laboratorio bioquimico-clinico.


In Argentina, the prevalence of obesity has increased considerably and type 2 diabetes mellitus (DMT2) reaches 12.7%. Obesity presents heterogeneity and the increase in abdominal fat may include hypertriglyceridemia, hyperglycemia, decrease in HDL-C, increases in apolipoprotein B (Apo B), increase in small and dense LDL lipoproteins, hyperinsulinemia, insulin resistance (IR), chronic inflammatory state, prothrombotic state and other metabolic alterations, which have been included in the so-called metabolic syndrome with 20 to 40% prevalence. Insulin resistance is present in 10 to 25% of the population and is associated with these alterations. The determination of IR is complex; it needs hospitalization and must be performed by specialists. In the laboratory, it can be estimated through insulin dosing, but it is not standardized, so it is necessary to have simple and accessible techniques. The triglycerides (TG)/HDL cholesterol (HDL-C) ratio can be an option using TG/C-HDL cutoff values ≥2.5 in women and ≥3.5 in men. It is significantly associated with IR and CVD and has good specificity but low discriminating power. So when it is present and there is a risk of T2DM or cardiovascular disease, CVD should be complemented with the calculation of non-HDL cholesterol or Apo B and the remaining cholesterol. Considering the pandemic of obesity and DMT2 and the high frequency of CVD, the TG/C-HDL ratio marker should be reported by the biochemical-clinical laboratory.

ABSTRACT

BACKGROUND: We evaluated the association of visceral-to-subcutaneous fat ratio (VSR) with nonalcoholic fatty liver disease (NAFLD) and advanced fibrosis degree based on noninvasive serum fibrosis markers in the general population with NAFLD.METHODS: This is a cross-sectional study, in 7,465 Korean adults who underwent health screening examinations. NAFLD was defined as fatty liver detected on ultrasonography, and visceral and subcutaneous abdominal fat was measured using computed tomography. We predicted fibrosis based on the fibrosis-4 (FIB-4) score and aspartate aminotransferase-to-platelet ratio index (APRI) and categorized the risk for advanced fibrosis as low, indeterminate, or high.RESULTS: The multivariable-adjusted prevalence ratios for indeterminate to high risk of advanced fibrosis based on FIB-4, determined by comparing the second, third, and fourth quartiles with the first quartile of VSR, were 3.38 (95% confidence interval [CI], 0.64 to 17.97), 9.41 (95% CI, 1.97 to 45.01), and 19.34 (95% CI, 4.06 to 92.18), respectively. The multivariable-adjusted prevalence ratios for intermediate to high degree of fibrosis according to APRI also increased across VSR quartiles (5.04 [95% CI, 2.65 to 9.59], 7.51 [95% CI, 3.91 to 14.42], and 19.55 [95% CI, 9.97 to 38.34], respectively). High VSR was more strongly associated with the prevalence of NAFLD in nonobese subjects than in obese subjects, and the associations between VSR and intermediate to high probability of advanced fibrosis in NAFLD were stronger in obese subjects than in nonobese subjects.CONCLUSION: High VSR values predicted increased NAFLD risk and advanced fibrosis risk with NAFLD, and the predictive value of VSR for indeterminate to high risk of advanced fibrosis was higher in obese subjects than in nonobese subjects.

ABSTRACT

Plasminogen activator inhibitor-1 (PAI-1) is a biomarker of thrombosis. Adipose and vascular tissues are among the major sources of PAI-1 production. Previous studies indicated that fat deposits mediate increased cardiovascular risk among obese individuals. We investigated the immunohistochemical (IHC) expression of PAI-1 in adipose and vascular tissues from the omentum and the subcutaneous tissue. The pathology samples were selected from 37 random patients who underwent elective abdominal surgery between 2008-2009. PAI-1 expression was semi-quantitatively scored and compared between the groups. Significant differences were noted in the IHC expression of PAI-1 between the omental and the subcutaneous adipose tissues (1.1 ± 0.8 versus 0.8 ± 0.6, respectively (p=0.05)). Adipose tissue displayed higher IHC expression of PAI-1 compared to vascular wall tissue in both omentum and subcutaneous sections (1.1 ± 0.8 versus 0.5 ± 0.9 (p=0.004), and 0.8 ± 0.6 versus 0.4 ± 0.6 (p=0.003), respectively). In conclusion, our study compared PAI-1 expression in the omentum versus the subcutaneous tissue and adipose versus vascular tissues. IHC expression of PAI-1 level was significantly higher in the omental adipose tissue compared to the subcutaneous adipose tissue. Adipose tissue displayed significantly higher PAI-1 expression than vascular tissue. The study elucidates the biological differences of adipose and vascular tissue from subcutaneous versus omental sections.

ABSTRACT

ABSTRACT BACKGROUND: During weight gain, most of the excess adipose tissue accumulates in the trunk. This alters the body shape and makes collection of anthropometric measurements, especially waist circumference (WC), difficult. OBJECTIVE: To evaluate the sensitivity and applicability of additional abdominal measurements in order to assess body composition of obese women. METHODS: A total of 30 women between 20 and 50 years of age and BMI above 30 kg/m² were assessed. Three WC measurements, were performed: at the umbilical scar designated as WC1 and at 8 and 16 cm above the umbilical scar, designated as WC2, and WC3 respectively. The correlation (r) between these anthropometric measurements and their sum was assessed against the parameters fat mass (FM), free fat mass (FFM), body fat percentage (%BF), and trunk fat percentage (%TF), obtained by total and trunk segmental bioelectric impedance analysis (BIA) as well as by the golden standard total and trunk dual energy X-ray absorptiometry (DXA). RESULTS: The measurements WC1, WC2, WC3, and their sum correlated strongly and moderately with the parameters FM, FFM, and %BF in total BIA and in both total DXA and trunk DXA. CONCLUSION: The results demonstrated a robust correlation between the sum of the three WC measurements and total and trunk DXA in obese women suggesting that such measurements may be a good indicator of body and trunk fat in women, actually superior to BIA results. The use of these three measurements may be an alternative for the assessment of body and trunk fat, in those cases in which the body shape due to adipose tissue trunk accumulation makes accurate classical measurement (WC1) difficult.


RESUMO CONTEXTO: O acúmulo de tecido adiposo excessivo no ganho de peso se dá em maior proporção no segmento do tronco, leva à alteração dos formatos corporais dificultando a tomada de medidas antropométricas, em especial a circunferência abdominal (CA). OBJETIVO: Avaliar a sensibilidade de medidas adicionais na região abdominal, considerando cada medida individualmente e sua somatória, e a aplicabilidade dessas medidas na avaliação da composição corporal de mulheres obesas. MÉTODOS: Foram avaliadas 30 mulheres com idade entre 20 e 50 anos e IMC acima de 30 kg/m² com a realização de três medidas de CA denominadas: CA1 padronizada na cicatriz umbilical, CA2 a 8 cm acima da cicatriz umbilical e CA3 a 16 cm acima da cicatriz umbilical. Foi avaliada a correlação (r) destas medidas antropométricas e de sua somatória com os parâmetros massa gorda (MG), massa livre de gordura (MLG), porcentagem de gordura corporal (%GC) e do tronco (%GT) obtidos por impedância bioelétrica (BIA) total e segmentar do tronco e por absorciometria de raios-X de dupla energia (DXA) total e do tronco, como padrão ouro. RESULTADOS: As medidas CA1, CA2, CA3 e a somatória das três tiveram correlação forte e moderada com os parâmetros MG, MLG e %GC tanto para BIA total como para DXA total e DXA do tronco. CONCLUSÃO: Os resultados deste estudo mostram forte correlação entre a soma das medidas de três pontos no abdome com DXA de tronco e total, em mulheres obesas, sugerindo serem estas medidas, um bom indicador de gordura corporal e de gordura da região do tronco, superior aos resultados obtidos por BIA. O uso dessas três medidas pode ser um indicador alternativo de avaliação da gordura corporal e de tronco, nos casos em que o formato corporal de acúmulo de gordura na região do tronco, dificultar a acurácia da medida clássica (CA1).

ABSTRACT

Introducción. La obesidad está asociada a un descenso acelerado de la función ventilatoria. Las formas más frecuentes de evaluar el estado nutricional y medir la grasa abdominal y las caderas son el índice de masa corporal (IMC) y el índice cintura-cadera (ICC). Existe escasa evidencia que sugiera su relación con la capacidad residual funcional (CRF). Nuestro objetivo fue determinar la relación entre el IMC, el ICC y la CRF en niños obesos de la ciudad de Talca, Chile. Población y métodos. Se reclutaron niños de ambos sexos (6-12 años). Se evaluaron peso, talla, IMC, ICC y función pulmonar a través de pletismografía corporal. Dependiendo de la distribución de los datos, se utilizó la prueba t de Student o U de Mann-Whitney para muestras independientes y, la prueba r de Pearson o Spearman para establecer la correlación entre ICC y CRF. Resultados. Los niños se dividieron en normopeso (n= 18) y obesos (n= 18). Se reportó una disminución significativa de la CRF (p= 0,025) en niños obesos y una relación inversa entre ICC y CRF, la cual fue moderada en niños normopeso (s= -0,489; p= 0,03) y alta en obesos (r= -0,681; p= 0,001). Conclusiones. Los niños obesos mostraron una menor CRF respecto de los normopeso, que, a su vez, se relacionó con el ICC. Estos resultados indican efectos sistémicos que produce la obesidad en la función ventilatoria en niños y la necesidad de incorporar indicadores de distribución de grasa corporal a temprana edad.


Introduction. Obesity is associated with a rapid decrease in ventilatory function. The most common way of assessing nutritional status and measuring abdominal fat and hips are the body mass index (BMI) and the waist-hip ratio (WHR). There is scarce evidence suggesting their relation to functional residual capacity (FRC). Our objective was to determine the relation among BMI, WHR, and FRC in obese children in the city of Talca, Chile. Population and methods. Male and female children were recruited (6-12 years). Weight, height, BMI, WHR, and pulmonary function were assessed; the latter with body plethysmography. Depending on data distribution, Student's t test or the Mann-Whitney U test were used for independent samples, while Pearson's or Spearman's r test was used to establish the correlation between WHR and FRC. Results. Children were divided into normal weight (n = 18) and obese (n = 18). A significant reduction in FRC (p = 0.025) was reported in obese children, while a reverse association was observed between WHR and FRC, which was moderate in normal weight children (s = -0.489; p = 0.03) and high in obese children (r = -0.681; p = 0.001). Conclusions. Obese children showed a lower FRC compared to normal weight children, which, in turn, was associated with WHR. These results are indicative of the systemic effects caused by obesity on children's ventilatory function and the need to use body fat distribution indicators at an early age.

ABSTRACT

Resumo O objetivo deste artigo é investigar a associação entre demência e indicadores antropométricos em idosos de Florianópolis. Estudo transversal, de base populacional, realizado com 1.197 idosos (≥ 60 anos) em 2013/2014. A demência foi considerada como a presença conjunta de escore baixo no Miniexame do Estado Mental (MEEM) e a incapacidade funcional moderada/grave nas atividades de vida diária (AVD). As variáveis independentes avaliadas foram: índice de massa corporal (IMC), perímetro da cintura (PC), índice de conicidade e relação cintura/estatura (RCEst). A regressão logística (bruta e ajustada) foi utilizada para identificar os fatores associados. A prevalência estimada de demência foi de 15,1%. Após ajustes para características sociodemográficas, estilo de vida e sintomas depressivos, a demência foi positivamente associada aos tercis superiores do IMC (OR: 2,32; IC95%: 1,26-4,25), PC (OR: 2,22; IC95%: 1,20-4,11) e RCEst. (OR: 2,30; IC95%: 1,19-4,43). De acordo com os resultados, tanto a obesidade quanto a gordura abdominal foram associados ao desfecho, sugerindo que o IMC, o PC e a RCEst. devam ser considerados na investigação dessa relação.


Abstract Objective To investigate the association between dementia and anthropometric indicators in the elderly from Florianópolis. Method This is a cross-sectional population-based survey performed with 1,197 elderly (≥ 60 years) in 2013/2014. Dementia was defined as the combined evidence of low MMSE (Mini-Mental State Examination) score and moderate/severe disability in the activities of daily living. The independent variables were body mass index (BMI), waist circumference (WC), conicity index and waist-to-height ratio (WHtR). Logistic regression (crude and adjusted) was performed to identify associated factors. Results Dementia prevalence was estimated at 15.1%. After adjustment for sociodemographic characteristics, lifestyle and depressive symptoms, dementia was positively associated with the upper tertiles of the BMI (OR: 2.32; CI95%: 1.26-4.25), WC (OR: 2.22; CI95%: 1.20-4.11) and WHtR (OR: 2.30; CI95%: 1.19-4.43). Conclusion Results have shown that both obesity and abdominal fat were associated with the outcome, suggesting that BMI, WC and WHtR should be considered in the investigation of this relationship.

ABSTRACT

BACKGROUND/AIMS: To examine whether visceral adiposity serves as a risk factor for colorectal cancer (CRC) and colorectal adenomas. METHODS: Two hundred healthy subjects, 200 patients with colorectal adenoma, and 151 patients with CRC (46 with early-stage and 105 with advanced-stage cancers) were enrolled at a tertiary referral hospital. All subjects underwent colonoscopy, and had laboratory data, and computed tomography (CT) scan available for abdominal fat measurement. An abdominal CT scan taken 1 to 4 years (mean interval, 20.6 months) before the diagnosis of CRC was also available in the 42 CRC patients. RESULTS: The mean areas of visceral adipose tissue (VAT) areas in the control, adenoma, early- and advanced-stage CRC groups were 94.6, 116.8, 110.4, and 99.7 cm², respectively (P0.05). The risk of both adenoma and CRC positively correlated with fasting plasma glucose levels (P for trend <0.05). In patients with early-stage cancer (n=17), VAT area decreased when the CT scan at diagnosis was compared with that taken before the diagnosis of CRC, but superficial adipose tissue area did not, so visceral-to-total fat ratio significantly decreased (46.6% vs. 50.7%, respectively, P=0.018) CONCLUSIONS: VAT area is related to the risk of colorectal adenoma. However, VAT decreases from the early stages of CRC. Impaired fasting glucose has a role in colorectal carcinogenesis.

ABSTRACT

BACKGROUND: Visceral adiposity index (VAI) was developed to estimate visceral fat, and its association with various diseases including cardiovascular disease, insulin resistance, and fatty liver has been revealed. The Chinese VAI (CVAI) has been newly developed in China. This study aimed to compare the VAI and CVAI for coronary artery calcification by using the coronary artery calcium score (CACs)-a predictable index of asymptomatic atherosclerosis.METHODS: We conducted a cross-sectional study that included 66,011 participants (76.3% male and 23.7% female participants) visiting an university hospital for medical check-ups between January 2014 and December 2016. A receiver operating characteristic curve analysis was performed and the area under the curve (AUC) was calculated to compare the concordance of the CACs and the VAI, CVAI, waist circumference, body mass index, triglycerides, and high-density lipoprotein cholesterol.RESULTS: In all participants, the AUC for the CVAI was the largest, while that for the VAI was fourth among all the indices (AUC(CVAI)=0.653, AUC(VAI)=0.592). The AUC for the CVAI was the largest among the indices in both sexes (female AUC(CVAI)=0.77, male AUC(CVAI)=0.592), while that for the VAI was the second largest (female, AUC(CVAI) 0.771>AUC(VAI) 0.651; male, AUC(CVAI) 0.592>AUC(VAI) 0.564).CONCLUSION: In conclusion, the CVAI showed a higher degree of concordance with CACs, which is an indirect indicator of cardiovascular disease, than the VAI in Korean adults.

ABSTRACT

BACKGROUND: Osteoporosis and osteopenia are characterized by reduced bone mineral density (BMD) and increased fracture risk. Although the risk of fractures is higher in underweight people than in overweight people, the accumulation of body fat (especially abdominal fat) can increase the risk of bone loss. This study aimed to evaluate the association between body fat percentage and BMD in normal-weight middle-aged Koreans. METHODS: This study included 1,992 adults (mean age, 48.7 years; 52.9% women). BMD and body fat were measured using dual-energy X-ray absorptiometry. Multiple linear regression analyses and analysis of covariance were used to assess the association between BMD and body fat. Body fat percentage was grouped by cut-off values. The cut-off values were 20.6% and 25.7% for men with a body mass index of 18.5–22.9 kg/m2, while the cut-off values were 33.4% and 36% for women. RESULTS: Body fat percentage tended to be negatively associated with BMD. Increased body fat percentage was associated with reduced BMD in normal-weight middle-aged adults. The effects of body fat percentage on BMD in normal-weight individuals were more pronounced in men than in women. CONCLUSION: There was a negative correlation between BMD and body fat percentage in middle-aged Korean men and women with normal body weight. This association was stronger in men than in women.

ABSTRACT

Introdução: A caracterização do perfil nutricional da população de adolescentes, assim como o diagnóstico de sobrepeso e obesidade, é de suma importância para auxiliar a elaboração de medidas de controle e reversão do quadro, possibilitando melhora na qualidade de vida e a prevenção das doenças crônicas não transmissíveis (DCNTs). Objetivo: Traçar o perfil nutricional e fatores associados (gênero, tipo de escola, idade e percepção da imagem corporal) em adolescentes de município de Minas Gerais. Material eMétodos: Estudo transversal, desenvolvido com estudantes de ambos os gêneros do ensino fundamental 2, com idade entre dez a dezesseis anos, matriculados em escolas públicas e privadas. Foram coletados dados antropométricos de 576 indivíduos, incluindo peso, altura e circunferência da cintura, padronizados de acordo com as orientações do Ministério da Saúde. Também foram coletados dados referentes ao hábito alimentar e a percepção da imagem corporal dos indivíduos, através de questionários semi-estruturados e auto preenchidos. Resultados: Dos adolescentes estudados, 58,7% pertenciam à rede pública de ensino, 64,9% do gênero feminino e a mediana de idade foi de 13 anos. Em relação ao estado nutricional, 1,5% da amostra encontrava-se com a estatura inadequada para a idade, 30,93% apresentavam excesso de gordura abdominal e 34,4% excesso de peso. Em relação a imagem corporal, observou-se que os indivíduos obesos e com sobrepeso apresentaram maior insatisfação com sua imagem corporal, quando comparados ao grupo dos indivíduos eutróficos. Em relação aos hábitos alimentares, 37,1% dos adolescentes relataram nunca realizar o café da manhã, mas em relação as outras refeições (almoço e janta) a maioria relatou consumir sempre. Em relação aos alimentos ultraprocessados, 41,2% dos adolescentes relataram consumir guloseimas diariamente e 33,2%, refrigerantes ou suco em pó. Conclusão: São necessárias medidas que promovam a alimentação saudável, visando a prevenção da obesidade, sobrepeso e das doenças crônicas não transmissíveis em adolescentes.


Introduction: The characterization of the nutritional profile of the adolescent population, as well as the diagnosis of overweight and obesity, is of paramount importance to help the elaboration of measures of control and reversion of the picture, allowing improvement in the quality of life and the prevention of chronic diseases noncommunicable diseases (NCDs). Objective: To describe the nutritional profile and associated factors (gender, school type, age and perception of body image) in adolescents from Minas Gerais. Material and Methods: A cross-sectional study, developed with students from both genders of elementary school 2, aged between ten and sixteen, enrolled in public and private schools. Anthropometric data were collected from 576 individuals, including weight, height and waist circumference, standardized according to the guidelines of the Ministry of Health. Data were also collected regarding dietary habits and body image perception of the individuals through semi- structured and self-filled. Results: Of the adolescents studied, 58.7% belonged to the public school system, 64.9% were female, and the median age was 13 years. Regarding nutritional status, 1.5% of the sample was inadequate for height, 30.93% had abdominal fat excess and 34.4% were overweight. Regarding body image, it was observed that obese and overweight individuals showed greater dissatisfaction with their body image, when compared to the group of eutrophic individuals. Regarding eating habits, 37.1% of adolescents reported never having breakfast, but in relation to other meals (lunch and dinner) the majority reported consuming always. In relation to ultraprocessed foods, 41.2% of adolescents reported consuming daily goodies and 33.2%, soft drinks or juice powder. Conclusion: Measures to promote healthy eating are needed to prevent obesity, overweight and chronic noncommunicable diseases in adolescents.

ABSTRACT

Resumo O objetivo deste estudo foi investigar a relação entre maus-tratos na família e excesso de peso, de gordura corporal e de gordura abdominal dos adolescentes da rede pública de ensino de município do Rio de Janeiro - Brasil. Trata-se de um estudo transversal que utiliza dados do Sistema de Vigilância de Fatores de Risco e Proteção à Saúde de Adolescentes, realizado em 2007, pelo município do Rio de Janeiro. A amostra foi composta por 1.628 escolares de 13 a 19 anos, de ambos os sexos, cursando o 9˚ ano do ensino fundamental. O excesso de peso, de gordura corporal e de gordura abdominal (desfechos) e os maus-tratos familiares (a agressão física e verbal) foram avaliados. A associação entre os maus-tratos e os desfechos foi realizada via modelos de regressão logística. Os maus-tratos apresentaram uma relação inversa com o excesso de peso e o de gordura para as meninas, mas somente a agressão física se associou significativamente com o excesso de peso (RC = 0,499; IC = 0,212-0,951). Já para os meninos, os resultados apontaram para o excesso de peso e de gordura mas sem significância estatística. Políticas de saúde devem considerar as diferenças existentes entre os gêneros no enfrentamento às experiências de violência que possam influenciar a saúde e o bem-estar do adolescente.


Abstract This study sought to investigate the relationship between domestic maltreatment and excess weight, body fat and abdominal fat among adolescents from the public schools in the city of Rio de Janeiro - Brazil. It involved a cross-sectional study using data from the Risk Factor Surveillance System and Protection of Health of Adolescents, held in 2007 by the municipality of Rio de Janeiro. The sample consisted of 1628 students aged 13 to 19 years, of both sexes, in the 9th year of school. Excess weight, body fat and abdominal fat (outcome variables) and domestic maltreatment (physical and verbal aggression) were evaluated. The association between domestic maltreatment and outcome variables was conducted via logistic regression models. Domestic maltreatment showed an inverse relationship to excess weight and fat for girls, but only physical aggression was significantly associated with excess weight (OR = 0.499, CI = 0.212 to 0.951). As for the boys, the results pointed to excess weight and fat but without statistical significance. Health policies must consider the differences between the genders in coping with experiences of violence that may influence the health and well-being of adolescents.

ABSTRACT

Los lipomas retroperitoneales son infrecuentes y suelen representar el 2.9% de los tumores primarios de origen en retroperitoneo1 . Pueden alcanzar gran tamaño y el diagnóstico diferencial debe hacer con el liposarcoma bien diferenciado, aunque es muy difícil de realizar en el preoperatorio2 . Se presenta el caso de un paciente con lipoma retroperitoneal cuyo diagnóstico se realizó por tomografía axial computada (TAC) y que fue extirpado en su totalidad.


Retroperitoneal lipomas are infrequent and can represent a 2.9 % of the primary tumors originated in the retroperitoneum. They can reach a great size and the differential diagnosis must be performed with the well differentiated liposarcoma, even though it is very difficult to establish it during the preoperative time. We describe herein a case of a patient with a retroperitoneal lipoma. The diagnosis was established with a computed axial tomography (CAT) and it was totally surgically removed.

ABSTRACT

BACKGROUND: Skeletal muscle plays a major role in glucose metabolism. We investigated the association between thigh muscle mass, insulin resistance, and incident type 2 diabetes mellitus (T2DM) risk. In addition, we examined the role of body mass index (BMI) as a potential effect modifier in this association. METHODS: This prospective study included 399 Japanese Americans without diabetes (mean age 51.6 years) who at baseline had an estimation of thigh muscle mass by computed tomography and at baseline and after 10 years of follow-up a 75-g oral glucose tolerance test and determination of homeostasis model assessment of insulin resistance (HOMA-IR). We fit regression models to examine the association between thigh muscle area and incidence of T2DM and change in HOMA-IR, both measured over 10 years. RESULTS: Thigh muscle area was inversely associated with future HOMA-IR after adjustment for age, sex, BMI, HOMA-IR, fasting plasma glucose, total abdominal fat area, and thigh subcutaneous fat area at baseline (P=0.033). The 10-year cumulative incidence of T2DM was 22.1%. A statistically significant interaction between thigh muscle area and BMI was observed, i.e., greater thigh muscle area was associated with lower risk of incident T2DM for subjects at lower levels of BMI, but this association diminished at higher BMI levels. CONCLUSION: Thigh muscle mass area was inversely associated with future insulin resistance. Greater thigh muscle area predicts a lower risk of incident T2DM for leaner Japanese Americans.

ABSTRACT

OBJECTIVES: Regenerative treatment using stem cells may serve as treatment option for empty nose syndrome (ENS), which is caused by the lack of turbinate tissue and deranged nervous system in the nasal cavity. We aimed to assess the efficacy and safety of the autologous stromal vascular fraction (SVF) in the treatment of ENS. METHODS: In this prospective observational clinical study, we enrolled 10 ENS patients who volunteered to undergo treatment of ENS through the injection of autologous SVF. Data, including demographic data, pre- and postoperative Sino-Nasal Outcome Test-25 (SNOT-25) scores, overall patient satisfaction, and postoperative complications, were prospectively collected. Nasal secretion was assessed using the polyurethane foam absorption method, and the levels of biological markers were analyzed in both ENS group and control group using enzyme-linked immunosorbent assay. The SVF extracted from abdominal fat was diluted and injected into both inferior turbinates. RESULTS: Among the 10 initial patients, one was excluded from the study. Subjective satisfaction was rated as “much improved” in two and “no change” in seven. Among the improved patients, the mean preinjection SNOT-25 score was 55.0 and the score at 6 months after injection was 19.5. However, the average SNOT-25 score of nine participants at 6 months after injection (mean±standard deviation, 62.4±35.8) did not differ significantly from the baseline SNOT-25 score (70.1±24.7, P>0.05, respectively). Among the various inflammatory markers assessed, the levels of interleukin (IL)-1β, IL-8, and calcitonin gene-related peptide were significantly higher in ENS patients. Compared with preinjection secretion level, the nasal secretions from SVF-treated patients showed decreased expressions of IL-1β and IL-8 after injection. CONCLUSION: Although SVF treatment appears to decrease the inflammatory cytokine levels in the nasal mucosa, a single SVF injection was not effective in terms of symptom improvement and patient satisfaction. Further trials are needed to identify a more practical and useful regenerative treatment modality for patients with ENS.

ABSTRACT

OBJECTIVE: To investigate the correlation between non-alcoholic fatty liver disease and visceral adipose tissue in non-obese Chinese adults using computed tomography (CT). MATERIALS AND METHODS: The study included 454 subjects undergoing abdominal CT scan. Degree of CT attenuation in liver and spleen, and the degree of fat infiltration in liver were evaluated according to three indices: the attenuation value of liver parenchyma (CTLP), the attenuation ratio of liver and spleen (LSratio) and the attenuation difference between liver and spleen (LSdif). Visceral fat area (VFA) and total fat area (TFA) at L2/3 and L4/5 levels were measured, and the abdominal subcutaneous fat area (SFA) was calculated. Bivariate correlation analysis was carried out to determine the correlation among these factors. RESULTS: In men, VFA, SFA and TFA at L2/3 and L4/5 levels showed significant differences in terms of the three indices to distinguish fatty liver from non-fatty liver (all, p < 0.001). In men, all the three indices showed negative correlation with TFA, SFA and VFA (all, p < 0.001). The negative correlation between the three indices and VFA at the L2/3 level was higher than at L4/5 level (r = −0.476 vs. r = −0.340 for CTLP, r = −0.502 vs. r = −0.413 for LSratio, r = −0.543 vs. r = −0.422 for LSdif, p < 0.001, respectively). The negative correlation between LSratio, LSdif and VFA at L2/3 and L4/5 levels was higher than SFA at the corresponding level. In women, all the three indices showed negative correlation with VFA and TFA at L2/3 and L4/5 levels, and the negative correlation between CTLP and VFA was higher at L2/3 level than at L4/5 level (r = −0.294 vs. r = −0.254, p < 0.001). CONCLUSION: In non-obese Chinese adults, the degree of hepatic fatty infiltration showed a strong correlation with abdominal fat on CT. VFA at L2/3 level was more closely related to fatty liver compared with VFA at L4/5 level.

ABSTRACT

PURPOSE: We aimed to investigate whether airway parameters, assessed via computed tomography (CT), are associated with abdominal fat areas and to compare the clinical characteristics of asthmatic patients with and without elevated visceral to subcutaneous fat area ratio (EV). METHODS: Asthmatic patients (aged ≥40 years) were prospectively recruited. Chest (airway) and fat areas were assessed via CT. Airway parameters, including bronchial wall thickness (WT), lumen diameter (LD), lumen area (LA), wall area (WA), total area (TA), as well as WA/TA percentage (wall area %) were measured at the apical segmental bronchus in the right upper lobe. Visceral (VFA), subcutaneous (SFA) and total (TFA) fat areas (cm2) were also measured. The correlations between abdominal fat areas and airway parameters were assessed. EV was defined as VFA/SFA ≥ 0.4. RESULTS: Fifty asthmatic patients were included (mean age 62.9 years; 52% female); 38% had severe asthma. Significant correlations were found between VFA and both LD and LA (r = −0.35, P = 0.01; r = −0.34, P = 0.02, respectively), and SFA and both WA and TA (r = 0.38, P = 0.007; r = 0.34, P = 0.02, respectively). Exacerbations, requiring corticosteroid therapy or ER visitation, were significantly more frequent in subjects without EV (83% vs. 34%, P = 0.05). CONCLUSIONS: Abdominal fat is associated with asthma, according to the location of fat accumulation. In asthmatic subjects, visceral fat seems to be attributable to the bronchial luminal narrowing, while subcutaneous fat may be related to thickening of bronchial wall.

ABSTRACT

PURPOSE: The purpose of this study was to demonstrate the prognostic significance of changes in body composition in patients with newly diagnosed hepatocellular carcinoma (HCC). MATERIALS AND METHODS: Patients (n=178) newly diagnosed with HCC participated in the study between 2007 and 2012. Areas of skeletal muscle and abdominal fat were directly measured using a three-dimensional workstation. Cox proportional-hazards modes were used to estimate the effect of baseline variables on overall survival. The inverse probability of treatmentweighting (IPTW) method was used to minimize confounding bias. RESULTS: Cutoff values for sarcopenia, obtained from receiver-operating characteristic curves, were defined as skeletal muscle index at the third lumbar vertebra of ≤ 45.8 cm/m2 for males and ≤ 43.0 cm/m2 for females. Sarcopenia patients were older, more likely to be female, and had lower body mass index. Univariable analysis showed that the presence of sarcopenia and visceral to subcutaneous fat area ratio (VSR) were significantly associatedwith prognosis. The multivariable analyses revealed that VSR was predictive of overall survival. However, in the multivariable Cox model adjusted by IPTW, sarcopenia, not VSR, were associated with overall survival. CONCLUSION: The presence of sarcopenia at HCC diagnosis is independently associated with survival.
