RESUMO
Metabolic-associated fatty liver disease (MAFLD) includes several metabolic dysfunctions caused by dysregulation in the brain-gut-liver axis and, consequently, increases cardiovascular risks and fatty liver dysfunction. In MAFLD, type 2 diabetes mellitus, obesity, and metabolic syndrome are frequently present; these conditions are related to liver lipogenesis and systemic inflammation. This study aimed to review the connection between the brain-gut-liver axis and MAFLD. The inflammatory process, cellular alterations in hepatocytes and stellate cells, hypercaloric diet, and sedentarism aggravate the prognosis of patients with MAFLD. Thus, to understand the modulation of the physiopathology of MAFLD, it is necessary to include the organokines involved in this process (adipokines, myokines, osteokines, and hepatokines) and their clinical relevance to project future perspectives of this condition and bring to light new possibilities in therapeutic approaches. Adipokines are responsible for the activation of distinct cellular signaling in different tissues, such as insulin and pro-inflammatory cytokines, which is important for balancing substances to avoid MAFLD and its progression. Myokines improve the quantity and quality of adipose tissues, contributing to avoiding the development of MAFLD. Finally, hepatokines are decisive in improving or not improving the progression of this disease through the regulation of pro-inflammatory and anti-inflammatory organokines.

There is a growing trend among consumers to seek out natural foods and products with natural ingredients. This shift in consumer preferences had a direct impact on both food and pharmaceutical industries, leading to a focus of scientific research and commercial efforts to meet these new demands. The aim of this work is to review recent available scientific data on foods of interest, such as the artichoke, gooseberry, and polygonoideae plants, as well as olive oil and red raspberries. Interestingly, the urgency of solutions to the climate change emergency has brought new attention to by-products of grapevine bunch stem and cane, which have been found to contain bioactive compounds with potential health benefits. There is a pressing need for a faster process of translating scientific knowledge from the laboratory to real-world applications, especially in the face of the increasing societal burden associated with non-communicable diseases (NCDs), environmental crises, the post-pandemic world, and ongoing violent conflicts around the world.
RESUMO
Pomegranate (Punica granatum L.) is a multipurpose dietary and medicinal plant known for its ability to promote various health benefits. Metabolic syndrome (MetS) is a complex metabolic disorder driving health and socioeconomic challenges worldwide. It may be characterized by insulin resistance, abdominal obesity, hypertension, and dyslipidemia. This study aims to conduct a review of pomegranate's effects on MetS parameters using a mechanistic approach relying on pre-clinical studies. The peel, juice, roots, bark, seeds, flowers, and leaves of the fruit present several bioactive compounds that are related mainly to anti-inflammatory and antioxidant activities as well as cardioprotective, antidiabetic, and antiobesity effects. The use of the juice extract can work as a potent inhibitor of angiotensin-converting enzyme activities, consequently regulating blood pressure. The major bioactive compounds found within the fruit are phenolic compounds (hydrolysable tannins and flavonoids) and fatty acids. Alkaloids, punicalagin, ellagitannins, ellagic acid, anthocyanins, tannins, flavonoids, luteolin, and punicic acid are also present. The antihyperglycemia, antihyperlipidemia, and weight loss promoting effects are likely related to the anti-inflammatory and antioxidant effects. When considering clinical application, pomegranate extracts are found to be frequently well-tolerated, further supporting its efficacy as a treatment modality. We suggest that pomegranate fruit, extract, or processed products can be used to counteract MetS-related risk factors. This review represents an important step towards exploring potential avenues for further research in this area.

Litchi (Litchi chinensis Sonn.) is a tropical fruit with various health benefits. The objective of this study is to present a thorough analysis of the cancer preventive and anticancer therapeutic properties of litchi constituents and phytocompounds. The Preferred Reporting Items for Systematic Reviews and Meta-Analysis criteria were followed in this work. Various litchi extracts and constituents were studied for their anticancer effects. In vitro studies showed that litchi-derived components reduced cell proliferation, induced cytotoxicity, and promoted autophagy via increased cell cycle arrest and apoptosis. Based on in vivo studies, litchi flavonoids and other extracted constituents significantly reduced tumor size, number, volume, and metastasis. Major signaling pathways impacted by litchi constituents were shown to stimulate proapoptotic, antiproliferative, and antimetastatic activities. Despite promising antineoplastic activities, additional research, especially in vivo and clinical studies, is necessary before litchi-derived products and phytochemicals can be used for human cancer prevention and intervention.

The aging of the global population has increased the prevalence of neurodegenerative conditions. Bacopa monnieri (BM), an herb with active compounds, such as bacosides A and B, betulinic acid, loliolide, asiatic acid, and quercetin, demonstrates the potential for brain health. Limited research has been conducted on the therapeutic applications of BM in neurodegenerative conditions. This systematic review aims to project BM's beneficial role in brain disorders. BM has anti-apoptotic and antioxidant actions and can repair damaged neurons, stimulate kinase activity, restore synaptic function, improve nerve transmission, and increase neuroprotection. The included twenty-two clinical trials demonstrated that BM can reduce Nuclear Factor-κB phosphorylation, improve emotional function, cognitive functions, anhedonia, hyperactivity, sleep routine, depression, attention deficit, learning problems, memory retention, impulsivity, and psychiatric problems. Moreover, BM can reduce the levels of pro-inflammatory biomarkers and oxidative stress. Here, we highlight that BM provides notable therapeutic benefits and can serve as a complementary approach for the care of patients with neurodegenerative conditions associated with brain disorders. This review adds to the growing interest in natural products and their potential therapeutic applications by improving our understanding of the mechanisms underlying cognitive function and neurodegeneration and informing the development of new therapeutic strategies for neurodegenerative diseases.
RESUMO
Type 2 diabetes mellitus (T2DM) is a widespread chronic disease characterized by persistent hyperglycemia, leading to severe complications such as diabetic cardiomyopathy and nephropathy, significantly affecting patient health and quality of life. The complex mechanisms underlying these complications include chronic inflammation, oxidative stress, and metabolic dysregulation. Diabetic cardiomyopathy, marked by structural and functional heart abnormalities, and diabetic nephropathy, characterized by progressive kidney damage, are major contributors to the increased morbidity and mortality associated with T2DM. AdipoRon, a synthetic adiponectin receptor agonist, has shown potential in preclinical studies for mimicking the beneficial effects of endogenous adiponectin, reducing inflammation and oxidative stress, and improving lipid metabolism and mitochondrial function. This systematic review evaluates the therapeutic potential of AdipoRon, focusing on its impact on diabetic cardiomyopathy and nephropathy. Through a comprehensive literature search and analysis, we highlight AdipoRon's role in ameliorating cardiovascular and renal complications in various animal models and cellular systems. The findings underscore the urgent need for translational clinical studies to validate AdipoRon's efficacy and safety in human populations, aiming to advance this promising therapeutic approach from experimental models to clinical application, potentially offering new hope for improved management of diabetic complications.
RESUMO
Alzheimer's disease (AD) is a stealthy and progressive neurological disorder that is a leading cause of dementia in the global elderly population, imposing a significant burden on both the elderly and society. Currently, the condition is treated with medications that alleviate symptoms. Nonetheless, these drugs may not consistently produce the desired results and can cause serious side effects. Hence, there is a vigorous pursuit of alternative options to enhance the quality of life for patients. Ginkgo biloba (GB), an herb with historical use in traditional medicine, contains bioactive compounds such as terpenoids (Ginkgolides A, B, and C), polyphenols, organic acids, and flavonoids (quercetin, kaempferol, and isorhamnetin). These compounds are associated with anti-inflammatory, antioxidant, and neuroprotective properties, making them valuable for cognitive health. A systematic search across three databases using specific keywords-GB in AD and dementia-yielded 1702 documents, leading to the selection of 15 clinical trials for synthesis. In eleven studies, GB extract/EGb 761® was shown to improve cognitive function, neuropsychiatric symptoms, and functional abilities in both dementia types. In four studies, however, there were no significant differences between the GB-treated and placebo groups. Significant improvements were observed in scores obtained from the Mini-Mental State Examination (MMSE), Short Cognitive Performance Test (SKT), and Neuropsychiatric Inventory (NPI). While the majority of synthesized clinical trials show that Ginkgo biloba has promising potential for the treatment of these conditions, more research is needed to determine optimal dosages, effective delivery methods, and appropriate pharmaceutical formulations. Furthermore, a thorough assessment of adverse effects, exploration of long-term use implications, and investigation into potential drug interactions are critical aspects that must be carefully evaluated in future studies.
RESUMO
Smallanthus sonchifolius, popularly known as yacon, is a member of the Asteraceae family. Due to its medicinal and edible value, yacon is consumed by different populations. Yacon is unique due to its high fructo-oligosaccharide and inulin content, as well as flavonoids, sesquiterpene lactones, and phenolic acids. Roots can be used to produce flour, which is less perishable and can be applied in various industrial products. This systematic review focuses on the effects of yacon flour on metabolic parameters. PubMed, Cochrane, Embase, Science Direct, Scopus, Web of Science, and Google Scholar databases were consulted, and PRISMA guidelines were followed in the selection of the studies. In total, 526 articles were found in the databases, and of these, only 28 full texts were eligible for inclusion. After applying the inclusion and exclusion criteria, seven studies were finally included. The results showed that the use of yacon flour can reduce glycemia, HbA1c, advanced glycation ends, plasma lipids, body fat mass, body weight, and waist circumference and improve intestinal microbiota and the antioxidant status. Further exploration of the effects of yacon flour is warranted, and additional clinical trials are necessary to determine the optimal daily consumption levels required to assist in improving metabolic parameters.
RESUMO
The treatment of Type 1 Diabetes Mellitus (T1DM) has always been a challenge for health professionals in relation to glycemic control. Increased body fat has been related to a worsening of the lipid profile and increased prevalence of dyslipidemia in this population, leading to negative repercussions on the control of cardiovascular risk. We aimed to investigate the distribution of lipid levels and the presence of dyslipidemia in children and adolescents with T1DM. A cross-sectional observational study was conducted with 81 individuals of both sexes (4-19 years) diagnosed with T1DM. Anthropometric and biochemical data were collected, in addition to data on physical activity level, sexual maturation stage, and insulin administration regimen. Lipid levels were categorized as normal, borderline, and elevated, and the presence of dyslipidemia was diagnosed by the presence of one or more altered lipid parameter. We noted a prevalence of dyslipidemia in 65.4% of the participants when considering borderline lipid values. Of those, 23.5% had one altered lipid level, and 42.0% had two or more. The main altered lipid levels were total cholesterol and triglycerides, followed by non-HDL-c. The main factor associated with the worsening of lipid levels was the increase in HbA1c. Sex had a significant effect on the levels of TC, HDL-c, and ApoA-I. The results of this study reinforce the need to monitor lipid profile in children and adolescents with T1DM, as well as the importance of early intervention in treating dyslipidemia, especially in patients with poor glycemic control.
RESUMO
Epicatechin is a polyphenol compound that promotes skeletal muscle differentiation and counteracts the pathways that participate in the degradation of proteins. Several studies present contradictory results of treatment protocols and therapeutic effects. Therefore, the objective of this systematic review was to investigate the current literature showing the molecular mechanism and clinical protocol of epicatechin in muscle atrophy in humans, animals, and myoblast cell-line. The search was conducted in Embase, PubMed/MEDLINE, Cochrane Library, and Web of Science. The qualitative analysis demonstrated that there is a commonness of epicatechin inhibitory action in myostatin expression and atrogenes MAFbx, FOXO, and MuRF1. Epicatechin showed positive effects on follistatin and on the stimulation of factors related to the myogenic actions (MyoD, Myf5, and myogenin). Furthermore, the literature also showed that epicatechin can interfere with mitochondrias' biosynthesis in muscle fibers, stimulation of the signaling pathways of AKT/mTOR protein production, and amelioration of skeletal musculature performance, particularly when combined with physical exercise. Epicatechin can, for these reasons, exhibit clinical applicability due to the beneficial results under conditions that negatively affect the skeletal musculature. However, there is no protocol standardization or enough clinical evidence to draw more specific conclusions on its therapeutic implementation.

Glycolipid metabolic disorders (GLMDs) are various metabolic disorders resulting from dysregulation in glycolipid levels, consequently leading to an increased risk of obesity, diabetes, liver dysfunction, neuromuscular complications, and cardiorenal vascular diseases (CRVDs). In patients with GLMDs, excess caloric intake and a lack of physical activity may contribute to oxidative stress (OxS) and systemic inflammation. This study aimed to review the connection between GLMD, OxS, metainflammation, and the onset of CRVD. GLMD is due to various metabolic disorders causing dysfunction in the synthesis, breakdown, and absorption of glucose and lipids in the body, resulting in excessive ectopic accumulation of these molecules. This is mainly due to neuroendocrine dysregulation, insulin resistance, OxS, and metainflammation. In GLMD, many inflammatory markers and defense cells play a vital role in related tissues and organs, such as blood vessels, pancreatic islets, the liver, muscle, the kidneys, and adipocytes, promoting inflammatory lesions that affect various interconnected organs through their signaling pathways. Advanced glycation end products, ATP-binding cassette transporter 1, Glucagon-like peptide-1, Toll-like receptor-4, and sphingosine-1-phosphate (S1P) play a crucial role in GLMD since they are related to glucolipid metabolism. The consequences of this is system organ damage and increased morbidity and mortality.

Mango and its by-products have traditional medicinal uses. They contain diverse bioactive compounds offering numerous health benefits, including cardioprotective and metabolic properties. This study aimed to explore the impact of mango fruit and its by-products on human health, emphasizing its metabolic syndrome components. PUBMED, EMBASE, COCHRANE, and GOOGLE SCHOLAR were searched following PRISMA guidelines, and the COCHRANE handbook was utilized to assess bias risks. In vivo and in vitro studies have shown several benefits of mango and its by-products. For this systematic review, 13 studies met the inclusion criteria. The collective findings indicated that the utilization of mango in various forms-ranging from fresh mango slices and mango puree to mango by-products, mango leaf extract, fruit powder, and mangiferin-yielded many favorable effects. These encompassed enhancements in glycemic control and improvements in plasma lipid profiles. Additionally, mango reduces food intake, elevates mood scores, augments physical performance during exercise, improves endothelial function, and decreases the incidence of respiratory tract infections. Utilizing mango by-products supports the demand for healthier products. This approach also aids in environmental conservation. Furthermore, the development of mango-derived nanomedicines aligns with sustainable goals and offers innovative solutions for healthcare challenges whilst being environmentally conscious.
RESUMO
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.

ABSTRACT: Pain in the cancer patient is an important clinical manifestation that results in low life expectancy and poor prognosis. Pain may be related to tumor type, invasion of adjacent tissues, metastasis, and diagnostic and therapeutic procedures with variable response to analgesic therapy. Many studies have called attention due to their potential therapeutic effect in the modulation of pain and inflammation. Cannabinoid derivatives are chemical compounds obtained from Cannabis that act on specific receptors.Several commercial products have already been approved in Europe and the USA for use in human patients. The present study aimed to review articles on the use of cannabinoids in the control of pain contributing to the well-being and quality of life in cancer patients undergoing palliative care. Although, there are few reports in the veterinary medical literature on the use of cannabinoids in the control of pain in dogs, it is believed that such patients can benefit from this therapeutic modality.
RESUMO: A dor no paciente com câncer é uma manifestação clínica importante que resulta em baixa perspectiva de vida e pior prognóstico. Esta dor pode estar relacionada ao tipo de tumor, à invasão em tecidos adjacentes, metástases, procedimentos diagnósticos e terapêuticos, com resposta variável à terapêutica analgésica. Muitos estudos têm chamado atenção para os derivados canabinoides, substâncias químicas obtidas a partir da Canabis que atuam em receptores específicos, por seu potencial efeito terapêutico na modulação da dor e da inflamação. Vários produtos comerciais já tiveram seu uso aprovado na Europa e EUA para uso em pacientes humanos. Objetivou-se pesquisar artigos sobre o uso de canabinoides no controle da dor no intuito de que os mesmos possam contribuir para o bem-estar e a qualidade de vida em pacientes oncológicos sob cuidado paliativo. Apesar de ainda serem escassos os relatos na medicina veterinária sobre o uso de canabinoides no controle da dor em cães, acredita-se que tais pacientes podem ser beneficiados por esta modalidade terapêutica.
RESUMO
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
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

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.

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.

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.

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
