The Influence of Body Fat and Lean Mass on HbA1c and Lipid Profile in Children and Adolescents with Type 1 Diabetes Mellitus.

Glycated hemoglobin (HbA1c) is used to assess glycemic control in Type 1 diabetes (DM1) patients. Apolipoproteins play an essential role in DM1 pathophysiology and may be associated with complications and HbA1c. This cross-sectional observational study of 81 children and adolescents of both sexes diagnosed with DM1 investigated the relationship between body fat distribution and lean mass with HbA1C and apolipoprotein values, analyzing biochemical and body composition measurements. A Shapiro-Wilk test with Lilliefors correction, a non-parametric Mann-Whitney test, and others were used with a significance level of 5%. The sample had a diagnosis time of 4.32 years and high blood glucose levels (mean 178.19 mg/dL) and HbA1c (mean 8.57%). Subjects also had a moderate level of adiposity, as indicated by arm and thigh fat areas. The study also found significant differences in the distribution of patients concerning levels of apolipoproteins A and B, with a smaller proportion of patients having undesirable levels. Finally, the study found a significant difference in the distribution of patients with estimated cardiovascular risk based on the ApoB/ApoA-I ratio. Conclusively, visceral fat in children and adolescents with DM1 may increase the risk of DM1 long-term complications owing to its association with elevated HbA1C and apolipoprotein values.

Accuracy of visceral adiposity indices and lipid accumulation products in the identification of adults at high cardiovascular risk.

INTRODUCTION: The lipid accumulation product (LAP) and visceral adipose index (VAI) are clinical markers of visceral obesity and were proposed as simple tools to estimate cardiovascular risk and mortality. The objective of this study was to analyze the accuracy of the VAI and LAP for high cardiovascular risk patients. METHODS: A cross-sectional observational study of accuracy was carried out in 193 patients of both sexes. In addition to the variables VAI and LAP, presence of comorbidities, education, level of physical activity and anthropometric data were obtained. Cardiovascular risk was determined by the Framingham score. RESULTS: No significant difference was observed in the sample in gender distribution (44.6% women; 55.4% men), 24.4% had low cardiovascular risk, 48.7% intermediate risk and 26.9% high cardiovascular risk. Linear regression analysis showed that VAI and LAP explain, respectively, only 2.4% and 5.2% of the variation in cardiovascular risk expressed by the Framingham score. The analysis of areas under the curve (AUC) for receiver operating characteristic (ROC) indicated a significant effect only of LAP to diagnose individuals with high cardiovascular risk, but with low sensitivity and specificity. CONCLUSION: Our results indicate that VAI and LAP explain only a small percentage of the variation in the Framingham cardiovascular risk score. LAP index still deserves more attention in a cohort study, because, even with the limitations of a cross-sectional study, we observed an acceptable sensitivity for it so that the LAP can be used as a screening criterion for requesting more accurate tests.

Effects of Medicinal Plants and Phytochemicals in Nrf2 Pathways during Inflammatory Bowel Diseases and Related Colorectal Cancer: A Comprehensive Review.

Inflammatory bowel diseases (IBDs) are related to nuclear factor erythroid 2-related factor 2 (Nrf2) dysregulation. In vitro and in vivo studies using phytocompounds as modulators of the Nrf2 signaling in IBD have already been published. However, no existing review emphasizes the whole scenario for the potential of plants and phytocompounds as regulators of Nrf2 in IBD models and colitis-associated colorectal carcinogenesis. For these reasons, this study aimed to build a review that could fill this void. The PubMed, EMBASE, COCHRANE, and Google Scholar databases were searched. The literature review showed that medicinal plants and phytochemicals regulated the Nrf2 on IBD and IBD-associated colorectal cancer by amplifying the expression of the Nrf2-mediated phase II detoxifying enzymes and diminishing NF-κB-related inflammation. These effects improve the bowel environment, mucosal barrier, colon, and crypt disruption, reduce ulceration and microbial translocation, and consequently, reduce the disease activity index (DAI). Moreover, the modulation of Nrf2 can regulate various genes involved in cellular redox, protein degradation, DNA repair, xenobiotic metabolism, and apoptosis, contributing to the prevention of colorectal cancer.

Insights into Pathogenesis, Nutritional and Drug Approach in Sarcopenia: A Systematic Review.

Sarcopenia is a multifactorial condition related to the loss of muscle mass and strength due to aging, eating habits, physical inactivity, or even caused by another disease. Affected individuals have a higher risk of falls and may be associated with heart disease, respiratory diseases, cognitive impairment, and consequently an increased risk of hospitalization, in addition to causing an economic impact due to the high cost of care during the stay in hospitals. The standardization of appropriate treatment for patients with sarcopenia that could help reduce pathology-related morbidity is necessary. For these reasons, this study aimed to perform a systematic review of the role of nutrition and drugs that could ameliorate the health and quality of life of sarcopenic patients and PRISMA guidelines were followed. Lifestyle interventions have shown a profound impact on sarcopenia treatment but using supplements and different drugs can also impact skeletal muscle maintenance. Creatine, leucine, branched-chain amino acids, omega 3, and vitamin D can show benefits. Although with controversial results, medications such as Metformin, GLP-1, losartan, statin, growth hormone, and dipeptidyl peptidase 4 inhibitors have also been considered and can alter the sarcopenic's metabolic parameters, protect against cardiovascular diseases and outcomes, while protecting muscles.

Organokines, Sarcopenia, and Metabolic Repercussions: The Vicious Cycle and the Interplay with Exercise.

Sarcopenia is a disease that becomes more prevalent as the population ages, since it is directly linked to the process of senility, which courses with muscle atrophy and loss of muscle strength. Over time, sarcopenia is linked to obesity, being known as sarcopenic obesity, and leads to other metabolic changes. At the molecular level, organokines act on different tissues and can improve or harm sarcopenia. It all depends on their production process, which is associated with factors such as physical exercise, the aging process, and metabolic diseases. Because of the seriousness of these repercussions, the aim of this literature review is to conduct a review on the relationship between organokines, sarcopenia, diabetes, and other metabolic repercussions, as well the role of physical exercise. To build this review, PubMed-Medline, Embase, and COCHRANE databases were searched, and only studies written in English were included. It was observed that myokines, adipokines, hepatokines, and osteokines had direct impacts on the pathophysiology of sarcopenia and its metabolic repercussions. Therefore, knowing how organokines act is very important to know their impacts on age, disease prevention, and how they can be related to the prevention of muscle loss.

Is Neck Circumference As Reliable As Waist Circumference for Determining Metabolic Syndrome?

Background: Metabolic syndrome (MS) comprises a cluster of risk factors for the development of cardiovascular diseases, which are among the leading causes of morbidity and mortality worldwide. Many studies have shown that neck circumference (NC) has validity in the measure of MS since it correlates positively with the traditional components. For these reasons, this study aimed at comparing waist circumference (WC) and NC for identifying MS parameters in patients treated at a cardiology unit. Methods: This study included 309 patients assisted in a Cardiology Unit. Biochemical and anthropometric parameters were evaluated. Correlations between neck and WC with anthropometric, biochemical, and atherogenic indices were evaluated. The diagnostic ability of neck and WC was assessed by using the receiver operating characteristics curve. Results: The patients had a mean age of 57.2 years, and 56% were men. The diagnosis of MS was present in 48% of men and 39% of women. Neck and WC showed a positive correlation with each other, and both showed positive correlations with the criteria for MS. Moreover, NC showed a positive correlation with body mass index (BMI), insulin, homeostatic model assessment (HOMA)-ß, and C-reactive protein. WC showed a positive correlation with BMI, HOMA of insulin resistance (HOMA-IR), and Castelli Index I. Both neck and WC showed the ability to identify the presence of the MS. Conclusion: Both neck and WC showed a significant correlation with several of the metabolic parameters, including some used as criteria for the diagnosis of MS. In addition, both measures demonstrated a good ability to predict MS, making these measures promising for screening patients with this syndrome.

Relação entre espessura da artéria Carótida, Vitamina D, Perfil Glicêmico e Antropometria / Relationship between Carotid artery thickness, Vitamin D, Glycemic Profile and Anthropometry

O objetivo foi avaliar se a espessura íntima carotídea está associada à vitamina D, perfil glicêmico e antropométrico. Foram coletados dados pessoais, antropométricos, bioquímicos e laudo de ultrassonografia carotídea, o qual foi utilizado a fim de avaliar o espessamento em milímetros e constatar ou não placas ateroscleróticas. As variáveis estudadas foram tratadas com o coeficiente de correlação de Pearson, ANOVA e Kruskal-Wallis. A média do IMC dos 51 pacientes foi de 29,47±6,39 kg/m². A espessura carotídea foi ≥1 mm em 54,90%. Quanto à vitamina D, 41,18% apresentaram hipovitaminose. A correlação da espessura carotídea com dados antropométricos, glicemia de jejum e HbA1c foi diretamente proporcional e inversamente com os valores de vitamina D, embora sem diferença significativa. As variáveis estudadas não puderam ser associadas com diferença significativa à espessura da camada média intimal da carótida nesta amostra.

The aim of this study was to evaluate the association of carotid intima thickness with vitamin D, glycemia and anthropometry. Personal, anthropometric and biochemical data, and carotid ultrasound report (to check thickening in millimeters and for the presence of atherosclerotic plaques) were collected. The variables studied were treated with Pearson's correlation coefficient, ANOVA and Kruskal-Wallis. The mean BMI of the 51 patients was 29.47 ± 6.39kg/m². The carotid thickness was ≥1mm in 54.90%. Regarding vitamin D, 41.18% had hypovitaminosis. The carotid thickness was directly proportionally correlated with anthropometric data, fasting blood glucose and HbA1c, and inversely correlated with vitamin D values, although without significant difference. The studied variables were not significantly associated with carotid intima thickness in this sample.

HDL-C and non-HDL-C levels are associated with anthropometric and biochemical parameters.

BACKGROUND: Dyslipidemias are associated with atherosclerosis and cardiovascular diseases. Recently, non-high-density lipoprotein cholesterol (non-HDL-c) has emerged as a new target for assessment and prediction of risk of cardiovascular disease (CVD) and is closely associated with atheroma plaque progression. OBJECTIVES: To evaluate associations between HDL-c and non-HDL-c levels and anthropometric and biochemical parameters and with the Castelli risk indexes I and II. METHODS: 300 randomly selected people were subdivided into two groups: patients with normal values for non-HDL-c and patients with altered values for non-HDL-c. These parameters were analyzed for associations with glycemia, total cholesterol (TC), triglycerides (TG), low-density lipoprotein (LDL-c), Castelli Index I (CI-I), Castelli Index II (CI-II), waist circumference (WC), body mass index (BMI) and presence of metabolic syndrome (MS). RESULTS: Glycemia, TC, TG, LDL-c, CI-I, CI-II, WC and BMI were all significantly different between subjects with normal and altered values of HDL-c and non-HDL-c. TC and WC both exhibited significantly higher values among patients with abnormal non-HDL-c when compared to patients with abnormal HDL-c. A significant difference was observed in occurrence of MS among patients with altered values of HDL-c and non-HDL-c. CONCLUSIONS: Our results show that both HDL-c and non-HDL-c are associated with insulin resistance, dyslipidemia, atherogenic indices, and obesity. There is therefore a need for randomized clinical intervention trials examining the potential role of non-HDL-c as a possible primary therapeutic target.

CONTEXTO: A dislipidemia está associada à aterosclerose e às doenças cardiovasculares. Recentemente, a lipoproteína de não alta-densidade de colesterol (não HDL-c) emergiu como um novo alvo para avaliação da predição de risco de doença cardiovascular, intimamente associada à progressão da placa de ateroma. OBJETIVOS: Avaliar as associações de níveis de HDL-c e não HDL-c com parâmetros antropométricos e bioquímicos, bem como com índices de Castelli I e II (CI-I e CI-II). MÉTODOS: Trezentas pessoas selecionadas aleatoriamente foram divididas em dois grupos: pacientes com valores normais de não HDL-c e pacientes com valores alterados de não HDL-c. Esses parâmetros foram associados a glicemia, colesterol total (CT), triglicerídeos (TG), lipoproteína de baixa densidade (LDL-c), CI-I, CI-II, circunferência de cintura (CC), índice de massa corporal (IMC) e presença de síndrome metabólica (SM). RESULTADOS: Glicemia, CT, TG, LDL-c, CI-I, CI-II, CC e IMC exibiram valores significativamente maiores para o não HDL-c quando comparado ao HDL-c. Uma diferença significativa na ocorrência de SM foi encontrada em pacientes com valores alterados de HDL-c e não HDL-c. CONCLUSÕES: Nossos resultados mostram que tanto o HDL-c quanto o não HDL-c estão associados a resistência à insulina, dislipidemia, índices de aterogênese e obesidade. Assim, há uma necessidade de futuros ensaios randomizados de intervenção clínica examinando o papel potencial do não HDL-c como possível alvo terapêutico primário.

Association between vitamin D status and metabolic syndrome risk factors.

BACKGROUND: The concern with the incidence of chronic-degenerative diseases is increasing worldwide, and many studies have shown that insufficiency of vitamin D (VD) can be linked to several metabolic disorders. AIMS: Thus, the objective of this study was to evaluate the association of the metabolic syndrome risk factors, atherogenic indices and VD in a group of patients attended at a Cardiology Center. METHODS: For this study, we invited 200 patients of both sexes attended in a Cardiology Center (Medical School of Marilia - São Paulo - Brazil). Most were female (n = 111) and aged between 41 and 70 years (from march to august, 2017). RESULTS: Our results showed that only 20.0% of the patients presented normal levels of VD. Patients with altered values for this vitamin presented significantly higher values for glycemia, HbA1c, Total cholesterol, LDL-c, triglycerides, Castelli Index I, Castelli Index II, Body Mass Index, waist circumference, non-HDL-c and the estimative of the size of the LDL-c particle. Vitamin D correlated negatively with glycemia, HbA1C, triglycerides, atherogenic indices, Body Mass Index, and blood pressure. Multiple Regression Model showed that for an individual to maintain metabolic parameters, at least at borderline values, the levels of VD should be 37.64 that is not in accordance with the reference values. CONCLUSIONS: These results showed a remarkable prevalence of low concentrations of Vitamin D in patients with cardiovascular risk factors.

Hypertension, C Reactive Protein and Metabolic Profile: What is the Scenario in Patients Undergoing Arteriography?

INTRODUCTION: High Blood Pressure (HBP), Diabetes Mellitus (DM), Metabolic Syndrome (MS) and Cardiovascular Diseases (CVD) are among the main causes of death worldwide and HBP is one of the most common chronic health problem representing an important and modifiable risk factor for vascular events and mortality. AIM: To study the association among high sensitivity CRP levels, and the biochemical, and anthropometric profile in hypertensive and non-hypertensive patients who underwent arteriography. MATERIALS AND METHODS: This research was performed at the Haemodynamic Laboratory of the University Hospital in the city of Marilia - state of São Paulo, Brazil. Ninety-five subjects who underwent arteriography were included. Anthropometric (body mass index and waist circumference) and biochemical parameters (glycaemia, total cholesterol, HDL-c, LDL-c, triglycerides, and high sensitivity C reactive protein), were evaluated. Variables pertaining to blood pressure, atherogenic indices, diagnosis of metabolic syndrome and catheterization details were collected. Statistical analysis was performed with Chi-square test, Fisher, Student t-test and ANOVA complemented by Tukey test. RESULTS: Our results showed that 78.95% of the patients who underwent arteriography were suffering from HBP. Hypertensive individuals had significantly higher glycaemia (124.14±45.33 mg/dL) or DM, higher values of triglycerides (195.27±74.52 mg/dL), waist circumference (98.52±12.52 cm), body mass index (29.99±1.41 kg/m2) and hs-CRP (0.53±0.44 mg/dL). Most of the hypertensive patients (93.33%) presented with MS and were related to the presence of more severe lesions in the arteries and had passed through more invasive procedures like angioplasty and surgery. CONCLUSION: Our findings indicate that blood pressure control is of paramount importance to ensure better quality of life and life expectancy as it is associated with several risk factors that increase the morbidity and mortality.

Metabolic syndrome and C reactive protein in patients undergoing angiography: Inevitable association?

BACKGROUND: The Metabolic Syndrome (MS) is characterized by a set of risk factors, which causes metabolic and inflammatory changes that increase vascular risk and may promote the development of atherosclerosis. Changes in lifestyle are related to obesity and associated diseases such as hypertension, type 2 diabetes mellitus, MS and cardiovascular disease (CVD). AIMS: This study aimed to evaluate the relationship of MS components and high sensitivity C Reactive Protein (hsCRP) in patients undergoing arteriography. METHODS: A group of patients undergoing arteriography was recruited in order we could evaluate the metabolic profile, levels of hsCRP and number of obstructions in the arteries. RESULTS: Most of our patients underwent arteriography are more likely to have hypertension, glucose intolerance, dyslipidemia, and central obesity, thus, MS is prevalent in this group. They also tend to exhibit higher values of hsCRP, lower values ​​for the estimative of the size of the LDL-c particle and higher number of obstruction in the arteries. CONCLUSION: We may say that the improvement of the above parameters could reduce inflammation and oxidative stress and vascular damages what would extend life expectancy and quality of life of this group of patients.

Reflections About Inflammatory Bowel Disease and Vitamins A and D.

Ulcerative colitis and Crohn's disease are two major forms of the inflammatory bowel diseases (IBDs). Vitamin A (VA) and vitamin D (VD) may be associated with reduction in inflammation in these disorders. The aim of this review was to show the current evidence that may associate VA and VD with IBDs. Data linking VA, VD, and IBDs were studied. Both VA and VD may be related to the immune system in different manners. The active form of VA, retinoic acid, may be related to the growth factor-ß and release of interleukin-10 (IL-10), thus involved with the resolution of the inflammation. Its deficiency is associated with the increase of disease activity. The active form of VD is 1,25(OH)2D3 that produces biological effects via the nuclear hormone receptor named VD receptor (VDR), which may interfere with the immune cells and macrophages leading to the suppression of the inflammatory process by decreasing the release of TNF-α, IL-1, IL-6, and IL-8, IL-12, and IL-23. VDR may also activate nucleotide-binding oligomerization domain 2 expression and stimulate the production of the defensin and cathelicidin that are important to the homeostasis of the mucosal immune barrier. The use of VA and VD could be helpful in the treatment and prevention of IBDs but more studies are necessary to establish the precise role of these compounds in the prevention or remission of these inflammatory processes.

Inflammatory bowel disease: can omega-3 fatty acids really help?

Adjuvants to the traditional therapy of inflammatory bowel disease (IBD) have been studied to enhance the efficacy of the treatment and improve patients' quality of life. Omega-3 polyunsaturated fatty acids (ω3FA) have been associated with attenuation of the inflammatory responses in IBD, possibly acting as substrates for anti-inflammatory eicosanoid production, similar to prostaglandins and leukotrienes. ω3FA also act as substrates for the synthesis of resolvins, maresins and protectins, indispensable in resolving inflammation processes. These acids may influence the development or course of IBD by: reducing oxidative stress, production of tumor necrosis factor-α and proinflammatory cytokines; working as chemopreventive agents; and decreasing the expression of adhesion molecules. There are numerous controversies in the literature on the effects of ω3FA in the prevention or treatment of IBD, but their effects in reducing inflammation is incontestable. Therefore, more studies are warranted to elucidate the pathophysiological mechanisms and establish the recommended daily intake to prevent or induce remission in IBD patients.

Perfil socioeconômico e antropométrico de candidatas a cirurgia bariátrica pelo Sistema Único de Saúde / Socio-economic and anthropometric profile of candidates for bariatric surgery by the National Health Service

A cirurgia bariátrica é considerada eficaz no controle e tratamento da obesidade grave, tendo como principais benefícios a melhora no perfil das comorbidades e consequente melhora na qualidade de vida. O objetivo deste estudo foi avaliar o perfil socioeconômico e antropométrico de obesas candidatas a cirurgia bariátrica. Foram estudadas cem pacientes do sexo feminino, com idade entre 20 e 45 anos, cadastradas pelo Sistema Único de Saúde. Entrevista individual foi realizada para a coleta dos dados. O índice de massa corporal foi calculado e classificado segundo a Sociedade Americana de Cirurgia Bariátrica. A classificação econômica foi estabelecida de acordo com a Associação Brasileira de Empresas de Pesquisa. A amostra apresentou média de idade de 33,3±6,0 anos. Os dados antropométricos apresentaram valores médios±DP de índice de massa corporal de 45,75±6,05Kg/m², prevalecendo o diagnóstico de obesidade mórbida (68%). Segundo a classificação econômica, a maioria das mulheres pertence à classe C. Das entrevistadas, 45% são casadas e 66% têm escolaridade igual ou superior ao ensino médio completo, sendo que os trabalhos domésticos representam a atividade de maior frequência (28%). Quanto ao início da obesidade, 38% desenvolveram na infância. A hipertensão arterial foi a comorbidade de maior predomínio (48%). Conclui-se que, a maioria das candidatas à cirurgia bariátrica, encontra-se casadas, sua principal atividade é cuidado doméstico, estão com IMC entre 40 e 50 kg/m2, tiveram o início da obesidade ainda na infância, apresenta o segundo grau completo e pertence à classe econômica C.

Bariatric surgery is efficient in the control and treatment of serious obesity. Its great assets are the essening of co-morbidities and improvement in life quality. Current analysis evaluates the socioeconomical and anthropometric profile of obese candidates for bariatric surgery. One hundred female patients, aged between 20 and 45 years, were selected by the National Health Service and an individual interview was undertaken for data collection. Body mass index was calculated and classified according to the American Society of Bariatric Surgery. Economic classification was established according to the Brazilian Association of Research Firms. Results showed a mean age of 33.3±6.0 years; mean rates±SD of body mass index of 45.75±6.05Kg/m², predominantly diagnosis for morbid obesity (68%). According to economic classification, most females belong to class C, corresponding to a mean family earning of R$ 927.00. Further, 45% are married and 66% have a high school diploma, with house chores as their main activity (28%). Obesity started during childhood in 38% of the interviewed, with arterial hypertension as the predominant co-morbidity (48%). Results showed that, although most females were within surgery standards, a certain percentage decided early for such an alternative without reaching higher BMI. In some cases, surgery was done without the previous conservative treatments.

Síndrome metabólica, aterosclerose e inflamação: tríade indissociável? / Metabolic syndrome, atherosclerosis and inflammation: an inseparable triad?

Observa-se, nas populações mundiais, aumento do sedentarismo e aumento do consumo de gorduras e açúcares, sendo estes vinculados normalmente aos alimentos industrializados. A consequência disso rapidamente se manifestou no aumento do sobrepeso/obesidade e na instalação de alterações fisiológicas e metabólicas, como a Síndrome Metabólica, que é representada por alterações na glicemia, nos lipídeos e na pressão arterial. Há evidências de ligação estreita entre estas alterações e os processos inflamatórios, que também podem estar associados ao estresse oxidativo. Estas condições levam à patogênese das alterações vasculares ou intensificam os processos metabólicos que acompanham a Síndrome Metabólica. O objetivo desta revisão foi comparar as inúmeras referências literárias que mostram correlação entre os componentes da Síndrome Metabólica e o aumento dos mediadores de inflamação. Para isso, utilizou-se Pubmed, Scopus, Lilacs e Scielo como base de dados, sendo que os artigos selecionados dataram principalmente dos últimos cinco anos.

Populations all over the world are increasingly inactive and are consuming increasing quantities of fats and sugars, which is generally linked to industrially processed foods. The consequences have rapidly manifest as an increase in overweight/obesity and in physiological and metabolic changes, such as the Metabolic Syndrome, which is a series of changes in glycemia, lipids and blood pressure. There is evidence of a close relationship between these changes and inflammatory processes, which can also be linked to oxidative stress. These conditions lead to the pathogenesis of vascular abnormalities or intensify metabolic processes that accompany the metabolic syndrome. The objective of this review is to compare the large number of bibliographic references that show correlations between components of the Metabolic Syndrome and increases in the mediators of inflammation. The publications reviewed were located using the Pubmed, Scopus, Lilacs and Scielo databases and the majority of the articles selected were published within the last 5 years.

Aspectos oxidativos da síndrome metabólica e aterosclerose / Oxidative aspects of metabolic syndrome and atherosclerosis

OBJETIVOS: Realizar uma revisão da literatura sobre os aspectos que envolvem o estresse oxidativo e seu papel na síndrome metabólica e na aterosclerose. MÉTODOS: A pesquisa foi realizada em abril e maio de 2015, utilizando as bases de dados PubMed, SciELO e LILACS e compreendendo as publicações a partir de 2011. Para a busca dos artigos foram utilizados os seguintes descritores: ((oxidative stress) AND (atherosclerosis OR metabolic syndrome)). Foram selecionados preferencialmente metanálises e ensaios clínicos contendo grande tamanho amostral. RESULTADOS: Estavam disponíveis 3934 artigos nas bases de dados ao buscar o período e os descritores informados (PubMed 3292, Scielo 588, Lilacs 54). Após eliminadas as referências duplas e aplicados os critérios de inclusão, foram selecionados 53 artigos para esta revisão. CONCLUSÕES: As alterações bioquímicas e antropométricas características da síndrome metabólica relacionam-se a processos inflamatórios e ao estresse oxidativo, que por sua vez estão diretamente relacionados à aterosclerose. Uma melhor compreensão de como as condições que definem a síndrome metabólica favorecem o estresse oxidativo pode contribuir de forma significativa para futuras abordagens ao paciente com doença cardiovascular.

AIMS: To review the literature on the current aspects of oxidative stress and its role in metabolic syndrome and in atherosclerosis. METHODS: The study was performed in April and May 2015 and the following databases were used: PubMed, SciELO, and LILACS, including articles published from 2011 onwards. The following keywords were used: oxidative stress and atherosclerosis or oxidative stress and metabolic syndrome. Meta-analyses and clinical trials with a large sample size were preferred. RESULTS: A total of 3,934 articles were available in the databases (PubMed 3,292; SciELO 588; and LILACS 54). Fifty-three articles were included in the review after eliminating double references and using the inclusion criteria. CONCLUSIONS: Biochemical and anthropometric findings characteristic of the metabolic syndrome are related to inflammatory processes and to oxidative stress which, in turn, are closely related to atherosclerosis. A better understanding of how the conditions that underlie metabolic syndrome predispose to oxidative stress may significantly contribute to the treatment of patients with cardiovascular disease in the future.

Consumo de sal em universitários de um curso de nutrição / Salt consumption of students from the nutrition course

Objetivo ­ Avaliar o consumo de sal dos alunos do curso de nutrição de uma universidade particular do interior do Estado de São Paulo a partir do exame de urina de 24 horas e identificar a frequência de consumo dos alimentos ricos em sódio, bem como correlacionar estas duas variáveis. Métodos ­ Para avaliar o consumo de sal foi utilizado o exame da excreção urinária de sódio das 24 horas. Para identificar a frequência de consumo dos alimentos ricos em sódio foi utilizado um questionário de frequência alimentar autoaplicável elaborado pelas pesquisadoras. Resultados ­ Fizeram parte deste estudo 30 alunos. O exame de excreção urinária de sódio das 24 horas indicou um consumo de sal médio de 7,65 ± 3,5g/dia, sem diferença significativa entre os seguimentos do curso (p=0,1048). A aplicação do questionário de frequência alimentar apontou um escore individual médio de 29 ± 10,6, sendo o valor mínimo de 8 e o máximo de 50, numa amplitude de variação entre 0 a 126. Os alunos que com menor escore de consumo de alimentos ricos em sódio apresentaram consumo de sal significativamente menor (p<0,0001) em relação ao que tiveram escores superiores. A correlação entre o escore individual do consumo de alimentos ricos em sódio e a ingestão de sal mostrou-se positiva e sem significância (r=0,1622, p=0,3918). Conclusões ­ Acumulam-se evidências que apontam para a necessidade de programas educacionais que atuem na motivação para agir, visto que conhecimento por si só não gera melhor consumo alimentar.

Objective ­ Evaluate the course of students' salt intake nutrition from a private university in the state of Sao Paulo from the urine test 24 hours and identify the frequency of consumption of foods high in sodium as well as correlate these two variables. Methods ­ To evaluate the consumption of salt was used an examination of urinary sodium excretion of 24 hours. To identify the frequency of high sodium consumption was used a food frequency survey developed by the researchers. Results ­ This study included 30 students. The examination of urinary sodium excretion of 24 hours indicated an average consumption of salt 7.65 ± 3.5g/day, with no significant difference between the segments of the course (p=0.1048). The application of the survey showed an average score of 29 ± 10.6, with a minimum value of 8 and a maximum of 50, in a range of variation between 0 and 126. Students with low scores of high sodium consumption showed a salt consumption significantly lower (p<0.0001) compared to those higher scores. The correlation between the individual score of consumption of high sodium foods was positive and not statistically significant (r=0.1622, p=0.3918). Conclusions ­ There are evidences pointing to the need for educational programs that operate on the motivation to act, because knowledge alone does not generate better food consumption.

Subnotificação da ingestão alimentar e fatores associados / Food intake underreporting and associated factors

OBJETIVO: Avaliar a subnotificação da ingestão energética e fatores associados entre mulheres que aguardam a cirurgia bariátrica no serviço público de saúde de uma cidade do interior do estado de São Paulo-Brasil. MÉTODOS: A amostra foi composta por 100 obesas. A ingestão energética (IE) e o nível de atividade física (NAF) foram estimados por meio de três recordatórios de 24 horas. O gasto energético em repouso(GER) foi medido pela calorimetria indireta. A razão ingestão energética relatada e gasto energético de repouso (IErel: GER) foi usada para avaliar a subnotificação, sendo o resultado comparado com pontos de corte derivados da equação de Goldberg. A associação entre a subnotificação e as características das mulheres foi avaliada pelo teste Z e a comparação entre os dados não paramétricos foi feita pelo teste de Mann-Whitney. Resultados e Conclusões: Houve diferença significativa entre os grupos de subnotificadoras e não subnotificadoras para a razão IErel:GER (p<0,0001). A proporção de subnotificação da ingestão energética foi de 47%, sendo maior entre mulheres que relataram níveis maiores de atividade física (p=0,006) e menor entre as que relataram níveis menores de atividade física (p=0,001). Quanto à escolaridade a maior proporção de subnotificação foi entre mulheres com ensino fundamental (p=0,002) e menor entre aquelas com ensino médio (p=0,03). A proporção de subnotificação também foi maior entre mulheres da classe econômica C ou inferior (p=0,049). As candidatas à cirurgia bariátrica apresentaram altas taxas de subnotificação da ingestão energética, especialmente a parcela das mulheres com menor escolaridade, baixa classe econômica e/ou mais ativas

OBJECTIVE: To assess the energy intake underreporting and associated factors among women waiting for bariatric surgery at the public healthcare service of a city in the state of São Paulo-Brazil. Methods: The sample consisted of 100 obese women.Three 24-hour recalls were used to estimate energy intake (EI) and physical activity level (PAL). Resting metabolic rate (RMR) was determined by indirect calorimetry.The ratio between reported energy intake and resting metabolic rate (rEI:RMR) wasused to assess the underreporting and the results were compared with the cut-off points obtained by the Goldberg equation. The association between under reporting and the women's characteristics was assessed by the Z-test and the non-parametric data were compared by the Mann-Whitney test. Results and Conclusions: The ratiorEI:RMR differed significantly between the underreporting and non-under reporting groups (p<0.0001). Forty-seven percent of women underreported their energy intake being that, this proportion was higher among women who reported higher physical activity levels (p=0.006) and lower among women who reported lower physical activity levels (p<0.001). The proportion of underreporting was also higher among women who had only completed elementary school (p<0.002) and lower among those who completed high school (p <0.03). Women belonging to the socioeconomic class Cor below also presented a higher proportion of underreporting (p<0.049). Bariatric surgery candidates present high rates of energy intake underreporting, especially those with lower education levels, of low socioeconomic classes and/or higher physical activity levels

Comparative analysis of approaches for assessing energy intake underreporting by female bariatric surgery candidates.

OBJECTIVE: To test six variations in the Goldberg equation for evaluating the underreporting of energy intake (EI) among obese women on the waiting list for bariatric surgery, considering variations in resting metabolic rate (RMR), physical activity, and food intake levels in group and individual approaches. METHODS: One hundred obese women aged 20 to 45 years (33.3 ± 6.08) recruited from a bariatric surgery waiting list participated in the study. Underreporting assessment was based on the difference between reported energy intake, indirect calorimetry measurements and RMR (rEI:RMR), which is compatible with the predicted physical activity level (PAL). Six approaches were used for defining the cutoff points. The approaches took into account variances in the components of the rEI:RMR = PAL equation as a function of the assumed PAL, sample size (n), and measured or estimated RMR. RESULTS: The underreporting percentage varied from 55% to 97%, depending on the approach used for generating the cutoff points. The ratio rEI:RMR and estimated PAL of the sample were significantly different (p = 0.001). Sixty-one percent of the women reported an EI lower than their RMR. The PAL variable significantly affected the cutoff point, leading to different proportions of underreporting. The RMR measured or estimated in the equation did not result in differences in the proportion of underreporting. The individual approach was less sensitive than the group approach. CONCLUSION: RMR did not interfere in underreporting estimates. However, PAL variations were responsible for significant differences in cutoff point. Thus, PAL should be considered when estimating underreporting, and even though the individual approach is less sensitive than the group approach, it may be a useful tool for clinical practice.
