ABSTRACT

Abstract Diabetes mellitus (DM) is a non-communicable disease throughout the world in which there is persistently high blood glucose level from the normal range. The diabetes and insulin resistance are mainly responsible for the morbidities and mortalities of humans in the world. This disease is mainly regulated by various enzymes and hormones among which Glycogen synthase kinase-3 (GSK-3) is a principle enzyme and insulin is the key hormone regulating it. The GSK-3, that is the key enzyme is normally showing its actions by various mechanisms that include its phosphorylation, formation of protein complexes, and other cellular distribution and thus it control and directly affects cellular morphology, its growth, mobility and apoptosis of the cell. Disturbances in the action of GSK-3 enzyme may leads to various disease conditions that include insulin resistance leading to diabetes, neurological disease like Alzheimer's disease and cancer. Fluoroquinolones are the most common class of drugs that shows dysglycemic effects via interacting with GSK-3 enzyme. Therefore, it is the need of the day to properly understand functions and mechanisms of GSK-3, especially its role in glucose homeostasis via effects on glycogen synthase.


Resumo O diabetes mellitus (DM) é uma doença não transmissível em todo o mundo, na qual existe nível glicêmico persistentemente alto em relação à normalidade. O diabetes e a resistência à insulina são os principais responsáveis ​​pelas morbidades e mortalidades de humanos no mundo. Essa doença é regulada principalmente por várias enzimas e hormônios, entre os quais a glicogênio sintase quinase-3 (GSK-3) é uma enzima principal e a insulina é o principal hormônio que a regula. A GSK-3, que é a enzima-chave, normalmente mostra suas ações por vários mecanismos que incluem sua fosforilação, formação de complexos de proteínas e outras distribuições celulares e, portanto, controla e afeta diretamente a morfologia celular, seu crescimento, mobilidade e apoptose do célula. Perturbações na ação da enzima GSK-3 podem levar a várias condições de doença que incluem resistência à insulina que leva ao diabetes, doenças neurológicas como a doença de Alzheimer e câncer. As fluoroquinolonas são a classe mais comum de drogas que apresentam efeitos disglicêmicos por meio da interação com a enzima GSK-3. Portanto, é necessário hoje em dia compreender adequadamente as funções e mecanismos da GSK-3, principalmente seu papel na homeostase da glicose via efeitos na glicogênio sintase.

ABSTRACT

La administración crónica de cafeína evita la alteración de la glucosa postprandial en ratas. El aumento en el consumo de la cafeína alrededor del mundo no es discutible, es así como su investigación se ha vuelto extensa en sus diferentes campos. Objetivo. Analizar los efectos de la administración crónica de cafeína en ratas alimentadas con dieta de cafetería, a través de evaluar índices de consumo, antropométricos y bioquímicos. Materiales y métodos. La dieta de cafetería es un modelo dietético equivalente a las características de la dieta occidental típica que origina síndrome metabólico en humanos. En esta investigación se realizó la administración crónica vía intraperitoneal de cafeína por ocho semanas a ratas adultas macho Wistar alimentadas con dieta de cafetería. Dada la poca evidencia acerca de los efectos biológicos y comportamentales de la administración crónica de dicha sustancia frente a un modelo de dieta de cafetería se evaluaron parámetros de consumo, antropométricos y bioquímicos. Resultados. La dieta de cafetería ocasionó anomalías asociadas al síndrome metabólico; no obstante, la administración de cafeína en las ratas alimentadas con esa dieta resultó ser un factor protector en la glucosa postprandial, más no en la alteración de la tolerancia a la glucosa o perfil lipídico. Conclusiones. La cafeína permitió proteger los niveles de glucosa postprandial al término del experimento y un descenso en el peso corporal y consumo de alimento solo en la primera semana. Sin embargo, no se observaron mejoras significativas en el perfil de lípidos, adiposidad, tolerancia a la glucosa y glucosa plasmática(AU)


Chronic caffeine administration prevents postprandial glucose disturbance in rats. The increase in caffeine consumption is not debatable, this is how his research has become extensive in his different fields. Objective. To analyze the effects of chronic administration of caffeine in rats fed a cafeteria diet, by evaluating consumption, anthropometric and biochemical indices. Previous studies refer to administering caffeine in diets high in carbohydrates and / or in fat that induce obesity or symptoms of metabolic syndrome. Material and methods. The cafeteria diet is a dietary model equivalent to the characteristics of the typical western diet that causes metabolic syndrome in humans. In this research, chronic intraperitoneal administration of caffeine was performed for 8 weeks to adult male Wistar rats fed a cafeteria diet. Given the little evidence about the biological and behavioral effects of the chronic administration of this substance against a cafeteria diet model, consumption, anthropometric and biochemical parameters were evaluated. Results. After eight weeks it was found that the cafeteria diet given to the controls caused abnormalities associated with the metabolic syndrome; regarding the administration of caffeine in the rats fed this diet, the treatment turned out to be a protective factor in postprandial glucose, but not in the alteration of glucose tolerance or lipid profile. Conclusions. Caffeine allowed to protect postprandial glucose levels at the end of the experiment and a decrease in body weight and food consumption only in the first week. However, no significant improvements were seen in lipid profile, adiposity, glucose tolerance, and plasma glucose(AU)

ABSTRACT

Insulin resistance is a pathological entity that can lead to alterations in lipid metabolism and can increase cardiovascular risk. Objective. The aim of this study was to assess the influence of different sociodemographic variables such as age, sex and social class and healthy habits such as smoking, physical activity and adherence to the Mediterranean diet on the cardiometabolic profile of Spanish workers. Material and methods. A descriptive, cross-sectional study was carried out in 1457 Spanish workers in an attempt to evaluate the effect of healthy habits (physical exercise determined with the IPAQ questionnaire, Mediterranean diet and tobacco consumption) and sociodemographic variables (age, sex and social class) on the values of different insulin resistance scales. Results. The progressive increase in the level of physical activity and high adherence to the Mediterranean diet achieved an improvement in the mean values and in the prevalence of elevated values in all the insulin resistance scales analyzed in this study. Age over 50 years and belonging to the least favored social classes (social classes II-III) were the variables that increased the risk of presenting insulin resistance. Male sex also increased the risk of presenting insulin resistance. Conclusions. The different healthy habits such as vigorous physical exercise and high adherence to the Mediterranean diet improve the values of the different scales that assess insulin resistance(AU)


La resistencia a la insulina es una entidad patológica que puede provocar alteraciones en el metabolismo de los lípidos y puede aumentar el riesgo cardiovascular. Objetivo. En este trabajo se pretende valorar la influencia de diferentes variables sociodemográficas como la edad, el sexo y la clase social y hábitos saludables como el consumo de tabaco, la actividad física y la adherencia a la dieta mediterránea en el perfil cardiometabólico de trabajadores españoles. Material y métodos. Se realizó un estudio descriptivo y transversal en 1457 trabajadores españoles intentando evaluar el efecto de los hábitos saludables (ejercicio físico determinado con el cuestionario IPAQ, dieta mediterránea y consumo de tabaco) y las variables sociodemográficas (edad, sexo y clase social) sobre los valores de diferentes escalas de resistencia a la insulina. Resultados. El aumento progresivo del nivel de actividad física y la alta adherencia a la dieta mediterránea consiguieron una mejoría en los valores medios y en la prevalencia de los valores elevados en todas las escalas de resistencia a la insulina analizadas en este estudio. La edad por encima de los 50 años y la pertenencia a las clases sociales menos favorecidas (clases sociales II-III) fueron las variables que aumentaron el riesgo de presentar resistencia a la insulina. El sexo masculino también incrementó el riesgo de presentar resistencia a la insulina. Conclusiones. Los diferentes hábitos saludables como el ejercicio físico vigoroso y la alta adherencia a la dieta mediterránea mejoran los valores de las diferentes escalas que valoran resistencia a la insulina(AU)

ABSTRACT

Objetivo: Revisar a implicação e a relação existente entre a microbiota intestinal e a síndrome do ovário policístico (SOP). Métodos: Trata-se de uma revisão sistemática de artigos das bases de dados PubMed, Cochrane e Science Direct dos últimos cinco anos, nos idiomas inglês, português e espanhol. Resultados: A disbiose da microbiota intestinal ativa o sistema imunológico do hospedeiro. Tal ativação interfere na função do receptor de insulina, causando hiperinsulinemia, o que aumenta a produção de androgênio ovariano e dificulta o desenvolvimento de um folículo saudável. Além disso, pacientes com SOP apresentam o perfil taxonômico alterado, o qual se associou inversamente com excesso de andrógenos e inflamação da SOP. Foi evidenciado que o uso de probióticos pode regular a resposta inflamatória, diminuir os níveis totais de testosterona e contribuir para que a SOP não prejudique uma possível gravidez. Conclusão: Essa revisão sugere que há íntima associação entre a disbiose microbiana e as alterações patológicas que ocorrem na SOP. Assim, a suplementação de probióticos em tais pacientes pode ter grandes benefícios, como melhora dos sintomas e redução das repercussões da doença.(AU)


Objective: To review the implication and the relationship between the intestinal microbiota and polycystic ovary syndrome. Methods: This is a systematic review of articles from the PubMed, Cochrane and Science Direct databases, from the last five years, in English, Portuguese and Spanish. Results: Dysbiosis of the intestinal microbiota activates the host's immune system. Such activation interferes with the function of the insulin receptor, causing hyperinsulinemia, which increases the production of ovarian androgens and hinders the development of a healthy follicle. In addition, patients with PCOS have an altered taxonomic profile, which is inversely associated with excess androgens and PCOS inflammation. It was evidenced that the use of probiotics can regulate the inflammatory response, decrease the total testosterone levels and contribute so that PCOS does not harm a possible pregnancy. Conclusion: This review suggests that there is a close association between microbial dysbiosis and pathological changes that occur in PCOS. Thus, supplementation of probiotics in such patients can have great benefits, such as improving symptoms and reducing the repercussions of the disease.(AU)

ABSTRACT

A síndrome dos ovários policísticos (SOP) é frequentemente acompanhada de distúrbio metabólico, principalmente dos carboidratos e dos lipídeos, aumentando o risco de síndrome metabólica. Por essa razão, alguns investigadores ainda denominam a SOP de síndrome metabólica-reprodutiva. O objetivo deste capítulo é descrever as principais repercussões metabólicas, bem como como investigá-las e saber como suas consequências podem ser deletérias para a saúde da mulher. Esta é uma revisão narrativa mostrando a implicação do metabolismo dos carboidratos e dos lipídeos nas dislipidemias, bem como da síndrome metabólica sobre o sistema reprodutor, e o risco cardiovascular da mulher com SOP. Conclui-se que o manejo adequado dos distúrbios metabólicos na SOP é benéfico a curto e a longo prazo tanto para o sistema reprodutor quanto para o cardiovascular.(AU)

ABSTRACT

RESUMEN El síndrome metabólico comprende un conjunto de factores de riesgo cardiovascular asociado a resistencia a la insulina, que propicia la aparición de enfermedad cardiovascular y de diabetes mellitus tipo 2. Su etiología se atribuye a la combinación de factores genéticos y ambientales, asociados al estilo de vida, que favorecen un estado proinflamatorio y protrombótico que empeora el cuadro clínico de los pacientes con covid-19. El objetivo de la revisión consistió en analizar el estado actual del conocimiento científico en las investigaciones sobre la interrelación entre los desórdenes del metabolismo glucídico y el síndrome metabólico, asociados a la condición proinflamatoria exacerbada en pacientes de covid-19. Se hicieron búsquedas en las bases de datos PubMed, SciELO, ClinicalKey y LILACS. Al proceso proinflamatorio generado por malos hábitos alimentarios, la sobrealimentación calórica de alto índice glicémico, y estilos de vida sedentarios, se atribuye un papel relevante en la patogénesis del síndrome metabólico, así como en sus posibles complicaciones en pacientes de covid-19 con comorbilidades asociadas. Es posible reducir la condición inflamatoria del síndrome metabólico mediante modificaciones en el estilo de vida y hábitos alimentarios, que prevengan la obesidad y sus efectos en la resistencia a la insulina, lo cual propicia reducir la gravedad asociada a los procesos inflamatorios inherentes (AU).


ABSTRACT Metabolic syndrome includes a set of cardiovascular risk factors associated with resistance to insulin, favoring the appearance of cardiovascular disease and diabetes mellitus type 2. Its etiology is attributed to the combination of genetic and environmental factors, associated to lifestyle, and favoring a proinflammatory and prothrombotic status that worsens the clinical characteristics of the patients with COVID-19. The objective of the review was to analyze the current state of the scientific knowledge in research on the interrelationship between glucide metabolism disorders and metabolic syndrome, associated with the exacerbated proinflammatory condition in COVID-19 patients. Searches were conducted in PubMed, SciELO, CinicalKey, and LILACS databases. A relevant role in the metabolic syndrome pathogenesis is attributed to the inflammatory process generated by poor eating habits, high caloric overfeeding, and to sedentary lifestyle, and also to possible complications with associated comorbidities in COVID-19 patients. It is possible to reduce the metabolic syndrome inflammatory condition through life style and alimentary habits changes that prevent obesity and its effects on insulin resistance and propitiate the reduction of the disease severity associated with the inherent inflammatory processes (AU).

ABSTRACT

ABSTRACT BACKGROUND AND OBJECTIVE: Considering the association between colorectal cancer (CRC) and both insulin resistance and obesity, and the prominent role of ghrelin in these metabolic disorders, we explored whether plasma levels of ghrelin were associated with CRC. Moreover, in the patients with CRC the possible correlations between ghrelin and insulin, insulin resistance, and body mass index (BMI) as an indicator of obesity were examined. METHODS: A total of 170 subjects, including 82 cases with CRC and 88 controls were enrolled in this study. Plasma levels of ghrelin, insulin, and glucose were measured in all the subjects using ELISA and glucose oxidase methods. Furthermore, insulin resistance was assessed by calculating HOMA-IR index. RESULTS: The cases with CRC had decreased ghrelin levels (P<0.001) and a higher HOMA-IR index (P<0.001) than controls. Interestingly, when CRC patients were stratified based on tumor site, lower ghrelin levels and a higher HOMA-IR index were observed in the patients with either colon or rectal cancer vs. controls too. Additionally, there were an age and BMI-independent negative correlation between ghrelin levels and HOMA-IR (r=-0.365, P<0.05), and an age-independent negative correlation between ghrelin levels and BMI (r=-0.335, P<0.05) in the rectal subgroup. CONCLUSION: Our findings support a role for ghrelin in connection with insulin resistance and obesity in CRC susceptibility; however, it needs to be corroborated by further studies.


RESUMO CONTEXTO E OBJETIVO: Considerando a associação entre câncer colorretal (CCR), a resistência à insulina, à obesidade e o papel proeminente da grelina nessas doenças metabólicas, foi explorado se os níveis plasmáticos de grelina estavam associados ao CCR. Além disso, nos pacientes com CCR foram pesquisadas as possíveis correlações entre a grelina, insulina, resistência insulínica e índice de massa corporal (IMC) como indicadores de obesidade. MÉTODOS: Foram incluídos neste estudo 170 indivíduos, sendo 82 com CRC e 88 controles. Os níveis plasmáticos de grelina, insulina e glicose foram medidos em todos os sujeitos utilizando métodos ELISA e glicose oxidase. Além disso, a resistência à insulina foi avaliada pelo cálculo do índice HOMA-IR. RESULTADOS: Os pacientes com CRC apresentaram redução dos níveis de grelina (P<0,001) e maior índice HOMA-IR (P<0.001) do que os controles. Curiosamente, quando os pacientes com CRC foram estratificados com base no local do tumor, níveis mais baixos de grelina e maior índice de HOMA-IR foram observados nos indivíduos com câncer de cólon ou retal versus controles também. Além disso, houve uma correlação negativa entre idade e IMC independente entre os níveis de grelina e HOMA-IR (r=-0,365, P<0,05) e uma correlação negativa independente da idade entre os níveis de grelina e IMC (r=-0,335, P<0,05) no subgrupo retal. CONCLUSÃO: Nossos achados apoiam o papel da grelina em relação à resistência à insulina e à obesidade na suscetibilidade do CRC; no entanto, ela precisa ser corroborada por estudos posteriores.

ABSTRACT

Introducción: La estrecha relación que existe entre diabetes mellitus tipo 2 y obesidad ha dado lugar a la creación del término "diabesidad", considerándose la nueva enfermedad del siglo XXI. La dupla entre estas produce grave lesión en el tejido hepático, músculo esquelético y sistema cardiovascular. Es importante un estilo de vida saludable y buena adherencia farmacológica para combatir esta pandemia. Objetivo: Describir aspectos generales acerca de la fisiopatología y el tratamiento de la diabesidad. Método: Se realizó una búsqueda bibliográfica no sistemática en las bases de datos Science Direct, EMBASE, LILACS, Redalyc, SciELO y PubMed. Los criterios de inclusión fueron publicaciones en inglés y español, en las que el título, palabras clave o resumen incluyen información pertinente al objetivo de estudio, periodicidad no mayor de cinco años. En la búsqueda se obtuvieron 50 artículos, de los cuales fueron seleccionados 35. Conclusión: La insulinorresistencia es el factor determinante para la progresión hacia diabetes mellitus tipo 2, en calidad de respuesta del tejido adiposo frente a altos niveles de ácidos grasos libres (lipotoxicidad), consecuencia de la obesidad, obligando al páncreas a secretar grandes cantidades de insulina, que con el tiempo compromete su funcionalidad. En la actualidad, existen diversas alternativas no farmacológicas, farmacológicas y quirúrgicas para el abordaje de la diabesidad, donde la prevención representa un aspecto de vital importancia(AU)


Introduction: The close relation among diabetes mellitus type 2 and obesity has led to the creation of the term "diabesity," considering it the new disease of XXI century. The fusion of these two diseases produces severe lesions in the hepatic tissue, the skeletal muscle and the cardiovascular system. It is important a healthy lifestyle and a good pharmacological adherence to fight this so called pandemic. Objective: Describe general aspects related to the physiopathology and treatment of diabesity. Method: It was carried out a non-systematic bibliographic search in databases like Science Direct, EMBASE, LILACS, Redalyc, SciELO and PubMed. The inclusion criteria were publications in English and Spanish language, with a periodicity of no more than 5 years, in which the title, keywords and abstract included information that will be relevant for the objective of the study. In the search 50 articles were found, of which 35 were selected. Conclusions: Insulin resistance is the key factor for the progression towards diabetes mellitus type 2, as a response of the adipose tissue to high levels of free fatty acids (lipotoxicity), which is a consequence of obesity, and obligates the pancreas to secrete big amounts of insulin that as time goes by compromises its functionality. Nowadays, there are different non-pharmacological, pharmacological and surgical alternatives to address the diabesity, in which prevention represents an aspect of vital importance(AU)

ABSTRACT

Introducción: El síndrome de ovario poliquístico se asocia con frecuencia a alteraciones cardiometabólicas; y su asociación con el fenotipo hipertrigliceridemia-obesidad abdominal ha sido poco estudiada en Cuba. Objetivo: Identificar la frecuencia del fenotipo hipertrigliceridemia-obesidad abdominal en mujeres de edad mediana con síndrome de ovario poliquístico y su asociación con la resistencia a la insulina, trastornos del metabolismo de la glucosa y ateroesclerosis subclínica. Método: Estudio descriptivo, transversal, en 30 mujeres. Se tomaron variables clínicas: edad, peso, talla, índice de masa corporal, circunferencia de cintura y cadera, índice cintura/cadera, tensión arterial, además de concentraciones de glucosa, insulina, colesterol total, triglicéridos, HDL-c y LDL-c, e índice HOMA-IR. La aterosclerosis subclínica se evaluó por doppler carotideo y ecocardiograma (hipertrofia ventricular izquierda y grasa epicárdica). El fenotipo hipertrigliceridemia-obesidad abdominal se definió como triglicéridos elevados (≥ 1,7 mmol/L) y circunferencia de la cintura ≥ 80 cm. Resultados: La frecuencia del fenotipo hipertrigliceridemia-obesidad abdominal fue 43,3 por ciento (13/30). Los valores medios de circunferencia abdominal, tensión arterial, así como de glucemia (p < 0,003), insulinemia (p = 0,028), triglicéridos (p < 0,0001), e índice HOMA-IR (p = 0,012) fueron más elevados en el grupo de mujeres con esa condición. A pesar de no haber diferencias significativas la frecuencia de mujeres con incremento del grosor íntima-media carotídeo y de grasa epicárdica fue superior en aquellas con el fenotipo. Conclusiones: La presencia del fenotipo hipertrigliceridemia-obesidad abdominal es frecuente en mujeres con síndrome de ovario poliquístico, y se asocia con alteraciones del metabolismo de la glucosa y la resistencia a la insulina. Este pudiera ser utilizado en la práctica clínica como un marcador de riesgo para alteraciones cardiometabólicas(AU)


Introduction: The polycystic ovary syndrome is frequently associated to cardiometabolic alterations; and its relation with the hypertriglyceridemic waist phenotype has been poorly studied in Cuba. Objective: Identify the frequency of the hypertriglyceridemic waist phenotype in middle age women with polycystic ovary syndrome and its association with insulin resistance, disorders in the glucose metabolism and subclinical atherosclerosis. Methods: Descriptive, cross-sectional study in 30 women. As clinical variables there were used: age, weight, size, body mass index, waist-hip circumference, waist/hip index, blood pressure; glucose, insulin, total cholesterol, triglycerides, HDL-c and LDL-c concentrations, and HOMA-IR index. Subclinical atherosclerosis was assessed by a carotid doppler and an echocardiogram (left ventricular hypertrophy and epicardial fat). The hypertriglyceridemic waist phenotype was defined as high triglycerides levels (≥ 1.7 mmol/L) and CC ≥ 80 cm. Results: The frequency of the hypertriglyceridemic waist phenotype was 43.3 percent (13/30). The mean values of abdominal circumference, blood pressure, as well as glycemia (p < 0.003), insulinaemia (p = 0.028), triglycerides (p < 0.0001), and HOMA-IR index (p = 0.012) were higher in the group of women with that condition. Although there were not significant differences, the frequency of women with increase of the carotid intima-media thickness and epicardical fat was higher in those with the phenotype. Conclusions: The presence of the hypertriglyceridemic waist phenotype is frequent in women with the polycystic ovary syndrome, and it is associated with alterations of the glucose metabolism and insulin resistance. This can be used in the clinical practice as a marker of risk for cardiometabolic alterations(AU)

ABSTRACT

Objetivo: Avaliar a qualidade da dieta de crianças e adolescentes com excesso de peso e determinar a relação com fatores de risco cardiometabólico. Métodos: Estudo quantitativo, transversal e analítico, realizado entre dezembro de 2016 e agosto de 2018, com crianças e adolescentes. Coletaram-se variáveis comportamentais (prática de atividade física e tempo de tela), antropométricas (peso, altura, índice de massa corporal, circunferência abdominal e do pescoço) e dietéticas (recordatório de 24 horas) e os dados bioquímicos foram consultados nos prontuários. Avaliou-se a resistência à insulina (RI), usando Homeostasis Model Assessment ­ Insulin Resistance (HOMA-IR), e a qualidade da dieta, por meio do Índice de Qualidade da Dieta Revisado (IQD-R). Análises realizadas pelos testes de Spearman e Mann-Whitney U, com nível de significância de 5%. Resultados: A amostra incluiu 100 crianças e adolescentes, sendo 71 (71%) do sexo feminino, média de idade de 9,42 ± 2,89 anos. IQD-R apresentou valor médio de 61,16 (IC 95%: 59,14 ­ 63,19) e nenhum participante apresentou dieta de boa qualidade. Não foram encontradas associações entre o escore do IQD-R e marcadores cardiometabólicos. Observaram-se associações negativas entre os componentes "vegetais totais e leguminosas" e HOMA-IR (r= -0,290), "vegetais verde-escuros, alaranjados e leguminosas" e HOMA-IR (r= -0,333) e "vegetais verde-escuros, alaranjados e leguminosas" com insulina de jejum (r= -0,291). Participantes com mais de três fatores de risco cardiometabólico tiveram pontuação significativamente maior do componente "gordura sólida e açúcar de adição". Conclusão: Nenhum participante investigado apresentou dieta qualitativamente adequada. A baixa ingestão de vegetais e leguminosas foi associada com marcadores de RI.

Objective: To assess the quality of the diet of children and adolescents with excess weight and determine its relationship with cardiometabolic risk factors. Methods: This quantitative descriptive cross-sectional study was carried out from December 2016 to August 2018 with children and adolescents. Behavioral (regular physical activity, screen time), anthropometric (weight, height, Body Mass Index, abdominal circumference, neck circumferences) and dietary (24-hour recalls) data were collected, and biochemical data were retrieved from medical records. Insulin resistance (IR) was measured using the Homeostasis Model Assessment ­ Insulin Resistance (HOMA-IR) and diet quality was assessed using the Revised Diet Quality Index (Índice de Qualidade da Dieta Revisado ­ IQD-R). Analyses using Spearman's and Mann-Whitney U tests were performed with a significance threshold set at 5%. Results: The sample consisted of 100 children and adolescents, 71 (71%) of whom were girls, and the mean age was 9.42±2.89 years. The mean IQD-R was 61.16 (95%CI: 59.14 ­ 63.19) and none of the participants presented a good quality diet. No associations were found between the IQD-R score and cardiometabolic markers. However, negative associations were observed between "total vegetables and legumes" and HOMA-IR (r=-0.290), "dark green and orange vegetables and legumes" and HOMA-IR (r=-0.333) and "dark green and orange vegetables and legumes" and fasting insulin (r=-0.291). The participants who presented more than three cardiometabolic risk factors had a significantly higher score on the "solid fat and added sugar" component. Conclusion: None of the participants had a qualitatively adequate diet. The low intake of vegetables and legumes was associated with IR markers.

ABSTRACT

BACKGROUND@#Little is known about the effects of environmental cobalt exposure on insulin resistance (IR) in the general adult population. We investigated the association between cobalt concentration and IR.@*METHODS@#A total of 1281 subjects aged more than 20 years with complete blood cobalt data were identified from the National Health and Nutrition Examination Survey (NHANES) 2015-2016 cycle. Blood cobalt levels were analyzed for their association with IR among all populations and subgroups by sex. Regression coefficients and 95% confidence intervals (CIs) of blood cobalt concentrations in association with fasting glucose, insulin and homeostatic model assessment of insulin resistance (HOMA-IR) were estimated using multivariate linear regression after adjusting for age, sex, ethnicity, alcohol consumption, body mass index, education level, and household income. A multivariate generalized linear regression analysis was further carried out to explore the association between cobalt exposure and IR.@*RESULTS@#A negative association between blood cobalt concentration (coefficient = - 0.125, 95% CI - 0.234, - 0.015; P = 0.026) and HOMA-IR in female adults in the age- and sex-adjusted model was observed. However, no associations with HOMA-IR, fasting glucose, or insulin were found in the overall population. In the generalized linear models, participants with the lowest cobalt levels had a 2.74% (95% CI 0.04%, 5.50%) increase in HOMA-IR (P for trend = 0.031) compared with subjects with the highest cobalt levels. Restricted cubic spline regression suggested that a non-linear relationship may exist between blood cobalt and HOMA-IR.@*CONCLUSIONS@#These results provide epidemiological evidence that low levels of blood cobalt are negatively associated with HOMA-IR in female adults.

ABSTRACT

This study focused on the ameliorative effects of gypenosides(GPS) on insulin sensitivity and inflammatory factors in rats with type 2 diabetes mellitus(T2 DM) and explored their possible molecular mechanisms. After the successful establishment of T2 DM model, diabetic rats were randomly divided into four groups, including model group, GPS groups(200, 100 mg·kg~(-1)) and metformin group(100 mg·kg~(-1)), with healthy rats serving as the control. After 6-week intragastric administration, fasting blood glucose(FBG) and oral glucose tolerance were examined. The levels of insulin, C-peptide, tumor necrosis factor-α(TNF-α), interleukin-1β(IL-1β), interleukin-6(IL-6) and C-reactive protein(CRP) in serum were examined. Then the homeostasis model assessment of insulin resistance(HOMA-IR) and insulin sensitivity index(ISI) were calculated. The protein expression levels of phosphorylated insulin receptor substrate-1(p-IRS-1) and phosphorylated protein kinase B(p-Akt) in skeletal muscle were measured by Western blot, as well as those of phosphorylated inhibitor of nuclear factor-κB(NF-κB) kinase β(p-IKKβ), phosphorylated alpha inhibitor of NF-κB(p-IκBα) and phosphorylated p65 subunit of NF-κB(p-p65) in adipose tissue. The relative expression levels of glucose transporter 4(GLUT4) mRNA in skeletal muscle and NF-κB mRNA in adipose tissue were measured by qRT-PCR, and the morphological changes of pancreatic tissue were observed. Compared with the model group, the GPS groups witnessed significant decrease in FBG, marked amelioration of impaired oral glucose tolerance and significant increase in ISI. Further, the high-dose GPS group saw significantly reduced HOMA-IR, TNF-α, IL-1β and CRP, significantly increased expression levels of p-IRS-1(Tyr), p-Akt and GLUT4, and markedly inhibited p-IRS-1(Ser), p-IKKβ, p-IκBα, p-p65 and NF-κB. The concentration of CRP and the expression levels of p-IRS-1(Ser), p-IKKβ, p-IκBα and NF-κB were remarkably reduced in the low-dose GPS group. However, GPS was found less effective in the regulation of serum insulin, C-peptide and IL-6 levels and the alleviation of pancreatic islet injury. The results indicated that GPS can reduce FBG and improve insulin sensitivity in diabetic rats possibly by regulating the NF-κB signaling pathway, inhibiting inflammation, and thereby regulating the expression of key proteins in the insulin signaling pathway.

ABSTRACT

This study explored the in vivo effects and mechanisms of the modern classical prescription Supplemented Gegen Qinlian Decoction Formula(SGDF) against diabetic kidney disease(DKD). Sixty rats were randomly divided into the normal group, model group, SGDF group, and rosiglitazone(ROS) group. The modified DKD rat model was established by employing the following three methods: exposure to high-fat diet, unilateral nephrectomy, and intraperitoneal injection of streptozotocin(STZ). After modeling, rats in the four groups were treated with double distilled water, SGDF suspension, and ROS suspension, respectively, by gavage every day. At the end of the 6 th week of drug administration, all the rats were sacrificed for collecting urine, blood, and kidney tissue, followed by the examination of rat general conditions, urine and blood biochemical indicators, glomerulosclerosis-related indicators, podocyte pyroptosis markers, insulin resistance(IR)-related indicators, and key molecules in the insulin receptor substrate(IRS) 1/phosphatidylinositol-3-kinase(PI3 K)/serine threonine kinase(Akt) signaling pathway. The results showed that SGDF and ROS improved the general conditions, some renal function indicators and glomerulosclerosis of DKD model rats without affecting the blood glucose(BG). Besides, they ameliorated the expression characteristics and levels of podocyte pyroptosis markers, alleviated IR, and up-regulated the protein expression levels of the key molecules in IRS1/PI3 K/Akt pathway to varying degrees. In conclusion, similar to ROS, SGDF relieves DKD by targeting multiple targets in vivo. Specifically, it exerts the therapeutic effects by alleviating podocyte pyroptosis and IR. This study has preliminarily provided the pharmacological evidence for the research and development of new drugs for the treatment of DKD based on SGDF.

ABSTRACT

The present study aims to investigate the effects of aerobic exercise and resistance exercise on lipid metabolism of skeletal muscle in high-fat diet (HFD)-induced insulin-resistant (IR) rats and the underlying mechanisms. Male Sprague-Dawley (SD) rats at age of 10 weeks were fed with HFD for 10 weeks to establish IR model. The IR rats were then randomly assigned into 3 groups, including IR control (IR) group, aerobic exercise (AE) group and resistance exercise (RE) group. An additional chow diet sedentary control (CON) group was used as well. Fasting blood glucose (FBG), insulin (FIN), glucagon and lipids, as well as triacylglycerol (TG), free fatty acids (FFA), and the protein expression of fatty acid translocase/cluster of differentiation 36 (FAT/CD36), carnitine palmitoyltransferase-1 (CPT-1), stearoyl-CoA desaturase-1 (SCD-1) and peroxisome proliferators-activated receptors γ (PPARγ) in skeletal muscles were measured after 8-week exercise interventions. The results showed that the contents of FBG, FIN, and LDL-C were increased by IR compared with CON group, and significantly decreased by aerobic exercise and resistance exercise; while aerobic exercise induced an increase in HDL-C as well. Furthermore, IR exhibited no significant effects on TG content of skeletal muscles, but significantly increased FFA level. Both aerobic and resistance exercise led to a decrease in TG content, and FFA level was increased by aerobic exercise but deceased by resistance exercise. In addition, the protein expression of FAT/CD36, SCD-1 and PPARγ was increased and that of CPT-1 was decreased by IR, while both types of exercise resulted in a decrease in the protein expression of FAT/CD36, SCD-1 and PPARγ, and an increase in CPT-1. In conclusion, aerobic and resistance exercise may attenuate IR through decreasing HFD-induced ectopic fat deposition and increasing β-oxidation of fatty acids in skeletal muscle cells, and resistance exercise shows a greater improvement in lipid metabolism of skeletal muscles than aerobic exercise.

ABSTRACT

BACKGROUND@#Obesity is a fundamental factor in metabolic disorders such as hyperlipidemia, insulin resistance, fatty liver, and atherosclerosis. However, effective preventive measures are still lacking. This study aimed to investigate different surgical protocols for removing partial adipose tissue before the onset of obesity and determine whether, and by which protocol, preliminary adipose removal could exert potent preventive effects against diet-induced metabolic disorders.@*METHODS@#Male low-density lipoprotein receptor (LDL-R) knockout (KO) mice were randomly divided into four groups and subjected to epididymal fat removal (Epi-FR) surgery, subcutaneous fat removal (suQ-FR) surgery, both subcutaneous and epididymal fat removal (Epi + suQ-FR) surgery, or sham-operation. After 1 week of recovery, all mice were given a high-fat diet (HFD) for 10 weeks to induce metabolic disorders.@*RESULTS@#In the Epi-FR group and the sham-operated group, the mean numbers of the residual subcutaneous fat were 28.59 mg/g and 18.56 mg/g, respectively. The expression of relative genes such as Pparg, Cebpa, Dgat2, Fabp4 and Cd36 in the residual subcutaneous fat increased 2.62, 3.90, 3.11, 2.06, 1.78 times in the Epi-FR group compared with that in the sham-operated group. Whereas in the other fat-removal groups, the residual fat depots had no significant change in either size or gene expression, as compared with those of the sham-operated group. Plasma lipid and glucose levels and insulin sensitivity, as detected by the glucose tolerance test, were not significantly alleviated in the three fat removal groups. Liver mass or lipid content was not attenuated in any of the three fat removal groups. The atherosclerosis burdens in the entire inner aorta and aortic root did not decrease in any of the three fat removal groups.@*CONCLUSIONS@#Our data suggest that removal of epididymal adipose or subcutaneous adipose alone or in combination before the onset of obesity did not protect against hyperlipidemia, insulin resistance, fatty liver, or atherosclerosis in LDL-R KO mice fed with a HFD. Hence, adipose removal possibly does not represent a potential approach in preventing obesity-related metabolic disorders in the obesity-susceptible population.

ABSTRACT

OBJECTIVE@#To observe the effect of acupuncture on vascular endothelial function in patients of polycystic ovary syndrome (PCOS) with impaired glucose tolerance (IGT) and normal glucose tolerance (NGT).@*METHODS@#A total of 140 patients with PCOS were divided into an IGT group (70 cases, 11 dropped off) and a NGT group (70 cases, 9 cases dropped off). The patients in the two groups were treated with full-cycle acupuncture at Zhongwan (CV 12), Guanyuan (CV 4), Qihai (CV 6), Tianshu (ST 25), etc. once every other day, 3 times a week, for 3 months. Before and after treatment, TCM symptom score, insulin resistance index [including fasting plasma glucose (FPG), 2-hour blood glucose (2hPG), fasting serum insulin (FINS), homeostasis model assessment of insulin resistance (HOMA-IR)] and vascular endothelial related factors [including asymmetric dimethylarginine (ADMD), endothelin-1 (ET-1), malondialdehyde (MDA), nitric oxide (NO)] were compared between the two groups; in addition, the obese subgroup and non-obese subgroup of the two groups were further compared.@*RESULTS@#Compared before treatment, the TCM symptom scores, ADMD, ET-1 and MDA after treatment were decreased (@*CONCLUSION@#Acupuncture could improve vascular endothelial function in PCOS patients, IGT patients have better efficacy than NGT patients, and obese patients have better efficacy than non-obese patients.

ABSTRACT

OBJECTIVES@#To study the effect of high-fat diet for maternal Sprague-Dawley rats at different stages on glucose and lipid metabolism in offspring and related mechanisms.@*METHODS@#According to the diet before pregnancy and during pregnancy and lactation, maternal rats were randomly divided into four groups (@*RESULTS@#Compared with the control diet groups (CC and CH groups), the groups with high-fat diet before pregnancy (HC and HH groups) had a significant increase in body weight (@*CONCLUSIONS@#High-fat diet for rats at different stages before and after pregnancy has different effects on glucose and lipid metabolism of offspring rats, and high-fat diet before pregnancy and during pregnancy and lactation has the greatest effect. The effect of high-fat diet on glucose and lipid metabolism of offspring rats is considered associated with the changes in the expression of genes involved in glucose and lipid metabolism.

ABSTRACT

OBJECTIVE@#To explore the effect of electro-acupuncture (EA) on glucose and lipid metabolism in unmarried patients with polycystic ovary syndrome (PCOS).@*METHODS@#Fifty-four PCOS patients were equally randomized into true acupuncture group and sham acupuncture group (control) for totally 16 weeks of treatment by random method with a computerized randomization program. Patients in true acupuncture group accepted traditional acupuncture methods with EA and two sets of acupoint groups were used alternatively. The first set consisted of Zhongji (CV 3), Qihai (CV 6), Guilai (ST 29), Sanyinjiao (SP 6), Yinlingquan (SP 9), Hegu (LI4) and Baihui (GV 20), and the second set consisted of Tianshu (ST 25), ST 29, CV 3, CV 6, SP 6, Taichong (LR 3), Neiguan (PC) 6 and GV 20. Patients in the sham acupuncture group accepted shallow acupuncture methods through EA without electricity at 4 non-meridian points in each shoulder and upper arm. Outcome measures included body mass index (BMI), waist-hip-ratio (WHR), oral glucose tolerance test (OGTT), insulin release test, glucose and lipid metabolism indicators such as total cholesterol (TC), triglycerides, high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol, adiponectin, leptin, visfatin, resistin, and interleukin (IL-6).@*RESULTS@#Twenty-six subjects in the true acupuncture group and 20 subjects in the sham group completed the clinical trial. After 16 weeks of treatment, no significant difference in the outcome measures were observed between the two groups (P>0.05). However, as compared with baseline data, a reduction in weight, BMI, hipline, WHR, fasting glucose, homeostatic model assessment of insulin sensitivity, visfatin and HDL-C, and an increase in resistin and IL-6 were observed in the true acupuncture group (P<0.05). In addition, a reduction in visfatin and an increase in TC were also observed in the sham group (P<0.05).@*CONCLUSIONS@#Acupuncture may have a beneficial effect in the treatment of PCOS by improving glucose and lipid metabolism. Moreover, the sham acupuncture may be not completely ineffective. Sham acupuncture may improve some of the aspects of the glucose and lipid metabolism of PCOS patients through a placebo effect.
