RESUMO

Fatty liver index (FLI) was developed as a simple and accurate marker of hepatic steatosis. FLI is derived from an algorithm based on body mass index, waist circumference, and levels of triglycerides and gamma-glutamyltransferase, and it is widely used in clinical and epidemiological studies as a screening tool for discriminating between healthy and nonalcoholic fatty liver disease (NAFLD) subjects. However, a systematic review of the literature regarding FLI revealed that this index has more extensive relationships with biochemical and physiological parameters. FLI is associated with key parameters of lipid, protein and carbohydrate metabolism, hormones, vitamins and markers of inflammation, or oxidative stress. FLI can be a predictor or risk factor for a number of metabolic and nonmetabolic diseases and mortality. FLI is also used as an indicator for determining the effects of health-related prevention interventions, medications, and toxic substances on humans. Although in most cases, the exact mechanisms underlying these associations have not been fully elucidated, they are most often assumed to be mediated by insulin resistance, inflammation, and oxidative stress. Thus, FLI may be a promising marker of metabolic health due to its multiple associations with parameters of physiological and pathological processes. In this context, the present review summarizes the data from currently available literature on the associations between FLI and biochemical variables and physiological functions. We believe that this review will be of interest to researchers working in this area and can provide new perspectives and directions for future studies on FLI. (AU)

RESUMO

We aimed to determine whether quercetin is capable of improving circadian rhythm and metabolism disorder under vitamin D-deficient condition. Middle-aged mice were randomly divided into four groups, namely, control (CON), vitamin D-deficient diet (VDD), quercetin (Q), and quercetin intervention in vitamin D-deficient diet (VDQ), with a total of 12 weeks’ intervention. Mice were sacrificed at zeitgeber time1 (ZT1) and ZT13 time points. At ZT1, circadian locomotor output cycle kaput (CLOCK) protein expression from VDD, Q, and VDQ groups; CRY1 from Q group; and CRY2 from VDD group were significantly lower compared to CON group. The mRNA expression of Sirt1, Bmal1, Clock, Cry1, and Cry2 in VDQ groups, also Bmal1, Clock, and Cry1 from Q group, were significantly decreased compared to CON group. At ZT13, compared to CON group, fasting insulin and homeostasis model assessment-insulin resistance (HOMA-IR) were higher in VDD group; BMAL1 was significantly increased, while CLOCK and CRY1 protein were significantly decreased from VDD group; CLOCK protein from VDQ group was significantly higher compared to CON, VDD, and Q groups, and also, BMAL1 protein expression from VDQ group was elevated compared to CON group. The mRNA expression of Bmal1, Clock, Per2, Cry1, and Cry2 in VDQ groups were significantly increased compared to CON groups. The mRNA expression of Bmal1 from VDQ group was decreased compared to both VDD and Q group. In conclusion, vitamin D-deficient diet resulted in a disordered liver circadian rhythm, and quercetin improved the hepatic circadian desynchronization. Quercetin supplementation might be effective for balancing circadian rhythm under vitamin D-deficient condition. (AU)

RESUMO

Background: The consumption of macronutrients rich insugars, mainly fructose, promote metabolic changes and in-duce insulin resistance, hepatic and extrahepatic fatty aciddeposits, as well as an increase in the generation of free rad-icals and oxidative stress.Methods: Randomized clinical study, 74 subjects partici-pated, divided into 2 group: a calorie-restricted diet (n=37)and a low-fructose diet (n=37). They were evaluated at thebeginning and 6 weeks after the implementation of the diet,using anthropometric and biochemical parameters. Descriptivestatistics were used to analyze the data, Student’s t test fortwo independent samples considering unequal variances andfor means of two paired samples. Level p<0.05 was consid-ered in each analysis test.Results: The body mass index (BMI) shows statisticallysignificant differences p< 0.05 in the group with calorie re-striction after applying the diet. The waist and hip circumfer-ence were modified by the implementation of the diet in eachindependent group (p<0.001 for each statistical difference,respectively), only the waist-hip index (WHR) was modifiedwhen the results were compared between both groups,p<0.05. In the biochemical parameters after the implementa-tion of the diets, in the low-fructose diet group an increase inblood glucose was observed from 175.97 to 187.40 mg/dl,cholesterol from 34.05 to 36.89 mg/dl and HDL from 104.77to 115.47 mg/dl. However, no statistically significant differ-ences were found when comparing both groups. No statisti-cally significant differences were observed in lipid peroxida-tion parameters or oxidized carbonyls.Conclusion: The modifications in hepatic metabolismcould be related to the energy quantity and the source ofmacronutrients.(AU)

RESUMO

Background and aims: some studies have reported links between 25-hydroxyvitamin D levels and the presence of metabolic syndrome. The aim of the present study was to evaluate whether an association exists among 25-hydroxyvitamin D, rs2282679 of the GC gene and metabolic syndrome (MS). Methods: the study involved a population of 134 postmenopausal obese females. Measurements of anthropometric parameters, blood pressure, bone turnover markers, fasting blood glucose, insulin resistance (HOMA-IR), lipid profile, C-reactive protein and prevalence of MS were recorded. Genotype of CG gene polymorphism (rs2282679) was evaluated. Results: insulin (delta: 4.6 ± 0.9 mUI/l; p = 0.02), triglycerides (delta: 21.6 ± 2.9 mg/dl; p = 0.04) and HOMA-IR (delta: 1.1 ± 0.9 unit; p = 0.02) were lower in TT subjects than TG + GG patients. The percentages of individuals who had MS (OR = 2.80, 95 % CI = 1.39-5.65; p = 0.02), hypertriglyceridemia (OR = 2.39, 95 % CI = 1.44-5.96; p = 0.01), and hyperglycemia (OR = 2.72, 95 % CI = 1.23-6.00; p = 0.43) were higher in G allele carriers. Logistic regression analysis showed an increased risk of MS in G allele carriers (OR = 2.36, 95 % CI = 1.11-5.91, p = 0.02) and an increased risk of 25-hydroxyvitamin D deficiency (< 20 ng/ml) (OR = 2.43, 95 % CI = 1.13-6.69, p = 0.02), too. Conclusions: a negative association among G allele and insulin resistance, hypertriglyceridemia, deficiency of 25 hydroxyvitamin D levels and MS was reported in this population. (AU)


Antecedentes y objetivos: algunos estudios han demostrado una relación entre los niveles de 25-hidroxivitamina D y la presencia del síndrome metabólico. El objetivo de este estudio fue evaluar si existe una asociación entre la 25-hidroxivitamina D, la variante rs2282679 del gen GC y el síndrome metabólico (SM). Métodos: el estudio involucró a una población de 134 mujeres obesas posmenopáusicas. Se registraron parámetros antropométricos, presión arterial, marcadores de recambio óseo, glucemia en ayunas, resistencia a la insulina (HOMA-IR), perfil lipídico, proteína C reactiva y prevalencia de SM. Se evaluó el genotipo del polimorfismo del gen CG (rs2282679). Resultados: los niveles de insulina (delta: 4,6 ± 0,9 mUI/l; p = 0.02), triglicéridos (delta: 21,6 ± 2,9 mg/dl; p = 0,04) y HOMA-IR (delta: 1,1 ± 0,9 unidades; p = 0,02) fueron menores en los sujetos TT que en los pacientes TG + GG. Los porcentajes de individuos que tenían SM (OR = 2,80, IC 95 % = 1,39-5,65; p = 0,02), hipertrigliceridemia (OR = 2,39, IC 95 % = 1,44-5,96; p = 0,01) e hiperglucemia (OR = 2,72, IC 95 % = 1,23-6,00; p = 0,43) fueron mayores en los portadores del alelo G. El análisis de regresión logística mostró un mayor riesgo de SM en los portadores del alelo G (OR = 2,36, IC 95 % = 1,11-5,91; p = 0,02) y un mayor riesgo de deficiencia de 25-hidroxivitamina D (< 20 ng/ml) (OR = 2,43, IC 95 % = 1,13-6,69; p = 0,02). Conclusiones: en esta población hemos detectado una asociación negativa entre el alelo G y la resistencia a la insulina, hipertrigliceridemia, deficiencia niveles de 25-hidroxivitamina D y SM. (AU)

RESUMO

Introducción: la acumulación excesiva de tejido adiposo se acompaña de alteraciones en el estado inflamatorio y aumento del estrés oxidativo, variables que se asocian con la resistencia a la insulina e incremento en los niveles de glucosa e insulina. las vitaminas y minerales refuerzan la capacidad antioxidante e inflamatoria, por lo que planteamos que podrían coadyuvar en el control de resistencia a la insulina y en el metabolismo de la glucosa y lípidos en un modelo de obesidad en rata. Objetivo: analizar el efecto de un suplemento multivitamínico sobre marcadores de resistencia a la insulina, inflamación y estrés oxidativo en ratas obesas con dieta de cafetería. Métodos: se dividieron aleatoriamente 35 ratas macho Wistar de 28 días de edad en cuatro grupos: 1, control dieta estándar; 2, dieta estándar más multivitamínico; 3, obesas con dieta de cafetería; y 4, obesas con dieta de cafetería más multivitamínico. Después de los tratamientos se analizaron los niveles de glucosa, HbA1c, insulina, TNF-α, IL-6, estrés oxidativo y perfil de lípidos por métodos colorimétricos, así como el porcentaje de tejido adiposo y los índices Homeostasis Model Assessment (HOMA) y Quantitative Insulin Sensitivity Check Index (QUICKI). Resultados: el suplemento multivitamínico disminuyó significativamente el tejido adiposo visceral, el índice HOMA, la glucosa, la HbA1c, el estrés oxidante y los marcadores inflamatorios en el grupo obeso más multivitamínico, en comparación con el grupo obeso con dieta de cafetería y el grupo control con dieta estándar. Sin embargo, en el grupo al que se le administró solo el multivitamínico sin dieta de cafetería aumentaron sus niveles de tejido adiposo total, glucosa y estrés oxidativo, así como el índice QUICKI con relación al grupo control con dieta estándar. (AU)


Introduction: excessive accumulation of adipose tissue is accompanied by alterations in the inflammatory state and increased oxidative stress, and these variables are associated with insulin resistance and increased glucose and insulin levels. On the other hand, vitamins and minerals reinforce the antioxidant and inflammatory capacity, for this reasons we propose that they could contribute to the control of insulin resistance, glucose and lipid metabolism in a rat model of obesity. Objective: to analyze the effect of a multivitamin supplement on markers of insulin resistance, inflammation, and oxidative stress in obese rats on a cafeteria diet. Methods: thirty-five 28-day-old male Wistar rats were randomly divided into four groups: 1, standard diet control; 2, standard diet plus multivitamin; 3, obese on a cafeteria diet; and 4, obese on a cafeteria diet plus multivitamin. After the treatments, glucose levels, HbA1c, insulin, TNF-α, IL-6, oxidative stress and lipid profile were analyzed by colorimetric methods, as well as the percentage of adipose tissue, Homeostasis Model Assessment (HOMA) index y Quantitative Insulin Sensitivity Check Index (QUICKI). Results: multivitamin supplementation significantly decreased visceral adipose tissue, HOMA index, glucose, HbA1c, oxidant stress, and inflammatory markers in the obese plus multivitamin rat group, compared with the obese cafeteria diet rat group and the standard diet rat control group. However, the group that was administered only the multivitamin without the cafeteria diet had increased levels of total adipose tissue, glucose, and oxidative stress, as well as the QUICKI index relative to the control group with the standard diet.

RESUMO

Objectives: manganese (Mn) is closely related to type 2 diabetes mellitus and insulin resistance (IR), but the exact mechanism is unclear. This study aimed to explore the regulatory effects and mechanism of Mn on IR using hepatocyte IR model induced by high palmitate (PA), high glucose (HG) or insulin. Methods: HepG2 cells were exposed to PA (200 μM), HG (25 mM) or insulin (100 nM) respectively, alone or with 5 μM Mn for 24 hours. The expression of key proteins in insulin signaling pathway, intracellular glycogen content and glucose accumulation, reactive oxygen species (ROS) level and Mn superoxide dismutase (MnSOD) activity were detected. Results: compared with control group, the expression of phosphorylated protein kinase B (Akt), glycogen synthase kinase-3β (GSK-3β) and forkhead box O1 (FOXO1) in the three IR groups was declined, and this decrease was reversed by Mn. The reduction of intracellular glycogen content and increase in glucose accumulation in IR groups were also inhibited by Mn. Additionally, the production of ROS was increased in IR models, compared with normal control group, while Mn reduced the excessive production of ROS induced by PA, HG or insulin. However, Mn did not alter the activity of MnSOD in the three IR models. Conclusion: this study demonstrated that Mn treatment can improve IR in hepatocytes. The mechanism is probably by reducing the level of intracellular oxidative stress, enhancing the activity of Akt/GSK-3β/FOXO1 signal pathway, promoting glycogen synthesis, and inhibiting gluconeogenesis.(AU)


Objetivos: el manganeso (Mn) está estrechamente relacionado con la diabetes mellitus tipo 2 y la resistencia a la insulina (RI), pero el mecanismoexacto aún no está claro. Este estudio tuvo como objetivo explorar los efectos reguladores y el mecanismo del Mn sobre la RI utilizando un modelode RI en hepatocitos inducido por palmitato alto (PA), glucosa alta (HG) o insulina.Métodos: las células HepG2 se expusieron a PA (200 μM), HG (25 mM) o insulina (100 nM), solas o junto con 5 μM de Mn durante 24 horas.Se evaluó la expresión de proteínas clave en la vía de señalización de la insulina, el contenido intracelular de glucógeno y la acumulación deglucosa, el nivel de especies reactivas de oxígeno (ROS) y la actividad superóxido dismutasa del manganeso (MnSOD).Resultados: en comparación con el grupo de control, la expresión de proteína quinasa B fosforilada (Akt), la glucógeno sintasa quinasa-3β(GSK-3β) y la proteína forkhead box O1 (FOXO1) en los tres grupos de RI se redujo, y esta disminución fue revertida por el Mn. La reduccióndel contenido de glucógeno intracelular y el aumento de la acumulación de glucosa en los grupos de RI también fueron inhibidos por el Mn.Además, la producción de ROS aumentó en los modelos de RI en comparación con el grupo de control normal. Mientras que el Mn redujo laproducción excesiva de ROS inducida por PA, HG o insulina. Sin embargo, el Mn no alteró la actividad de la MnSOD en los tres modelos de RI.Conclusión: este estudio demostró que el tratamiento con Mn puede mejorar la RI en hepatocitos. El mecanismo probablemente sea mediantela reducción del nivel de estrés oxidativo intracelular, mejorando la actividad de la vía de señalización Akt/GSK-3β/FOXO1, promoviendo la síntesisde glucógeno e inhibiendo la gluconeogénesis.(AU)

RESUMO

Background and aim: Continuous Positive Airway Pressure (CPAP) is the most effective therapy for symptomatic obstructive sleep apnoea (OSA). However, uncertainty remains about the effectiveness of CPAP in improving OSA-related metabolic dysregulation. This meta-analysis of randomized controlled trials (RCTs) aimed to investigate whether CPAP, compared to other control treatments, could improve glucose or lipid metabolism in OSA patients. Methods: Relevant articles were searched in three different databases (MEDLINE, EMBASE and Web of Science) from inception to 6th Feb 2022 through specific search terms and selection criteria. Results: From a total of 5553 articles, 31 RCTs were included. CPAP modestly improved insulin sensitivity as determined by mean fasting plasma insulin and Homeostasis Model Assessment of Insulin Resistance reduction of 1.33mU/L and 0.287, respectively. In subgroup analyses pre-diabetic/type 2 diabetic patients as well as those with sleepy OSA showed a greater response to CPAP. Regarding lipid metabolism, CPAP was associated with a mean total cholesterol reduction of 0.064mmol/L. In subgroup analyses, the benefit was higher in patients that showed more severe OSA and oxygen desaturations at the baseline sleep study as well as in younger and obese subjects. Neither glycated haemoglobin nor triglycerides, HDL- and LDL-cholesterol were reduced by CPAP. Conclusion: CPAP treatment may improve insulin sensitivity and total cholesterol levels in OSA patients but with low effect size. Our results suggest that CPAP does not substantially improve metabolic derangements in an unselected OSA population, but the effect may be higher in specific subgroups of OSA patients. (AU)

RESUMO

Obesity is a major contributor to the silent and progressive development of type 2 diabetes (T2D) whose prevention could be improved if individuals at risk were identified earlier. Our aim is to identify early phenotypes that precede T2D in diet-induced obese minipigs. We fed four groups of minipigs (n = 5–10) either normal-fat or high-fat high-sugar diet during 2, 4, or 6 months. Morphometric features were recorded, and metabolomics and clinical parameters were assessed on fasting plasma samples. Multivariate statistical analysis on 46 morphometrical and clinical parameters allowed to differentiate 4 distinct phenotypes: NFC (control group) and three others (HF2M, HF4M, HF6M) corresponding to the different stages of the obesity progression. Compared to NFC, we observed a rapid progression of body weight and fat mass (4-, 7-, and tenfold) in obese phenotypes. Insulin resistance (IR; 2.5-fold increase of HOMA-IR) and mild dyslipidemia (1.2- and twofold increase in total cholesterol and HDL) were already present in the HF2M and remained stable in HF4M and HF6M. Plasma metabolome revealed subtle changes of 23 metabolites among the obese groups, including a progressive switch in energy metabolism from amino acids to lipids, and a transient increase in de novo lipogenesis and TCA-related metabolites in HF2M. Low anti-oxidative capacities and anti-inflammatory response metabolites were found in the HF4M, and a perturbed hexose metabolism was observed in HF6M. Overall, we show that IR and progressively obese minipigs reveal phenotype-specific metabolomic signatures for which some of the identified metabolites could be considered as potential biomarkers of early progression to TD2.

RESUMO

The aim of this study is to determine the concordance between the insulin resistance indicators, HOMA and TyG, because ofa moderate intensity aerobic exercise session in sedentary young women. Methods: A total of 22 sedentary women between 18 and 35 years of age participated in this research. HOMA and TyG indiceswere determined before and after a moderate intensity aerobic exercise (MIAE), based on Heart Rate reserve. Spearman andKendall’s Tau-b were used to evaluate the association between those variables. Values were compared using the Bland &Altman graphs: Kappa Coefficient was used to estimate the proportion of concordance observed between both indicators. Significant differences were considered at a p≤0.01.Results: Spearman's Rho correlation and Kendall's Tau-b before MIAE were significant and direct (r=0.634, p<0.001 andr=0.480, p<0.01; respectively) with a Cohen's Kappa index of k=0.585. After MIAE, Spearman's Rho correlation and Kendall'sTau-b were also significant and direct r=0.650, p<0.001 and r=0.504, p<0.001, respectively, with a lower Cohen's Kappa index(k=0.390). Conclusions: TyG index is a good indicator to evaluate insulin resistance at baseline situations. However, this index doesn’tproperly determine insulin resistance after a MIAE.(AU)

RESUMO

Antecedentes: a pesar de la relación de la resistina con el síndrome metabólico (SM), no se ha evaluado la relación del polimorfismo de nucleótido único (SNP) rs7139228 con variante C/T del intrón 5´UTR del gen RETN con la presencia de SM. Objetivo: el objetivo del presente estudio es evaluar la influencia del SNP rs7139228 del gen RETN sobre las concentraciones de resistina circulante, así como sobre el SM en sujetos obesos. Material y métodos: se reclutó una población caucásica de 1003 sujetos obesos. En todos los sujetos se realizó un análisis antropométrico (peso, perímetro de cintura, masa grasa), una evaluación de la ingesta nutricional, un estudio bioquímico (glucosa, insulina, proteína C-reactiva, perfil lipídico, insulina, HOMA-IR, resistina) y una evaluación del genotipo rs7139228. Resultados: la distribución del genotipo fue la siguiente: 852 sujetos con GG (84,9 %), 147 sujetos con GA (14,7 %) y 4 sujetos con AA (0,4 %). La frecuencia alélica fue G (0,92) y C (0,08). Las concentraciones séricas de resistina (delta: 1,7 ± 0,2 ng/ml; p = 0,01), insulina (delta: 4,2 ± 0,4 UI/L; p = 0,01) y HOMA-IR (delta: 1,9 ± 0,2 unidades; p = 0,03) fueron mayores en los pacientes portadores del alelo A que en los no portadores. La prevalencia global del SM fue del 48,1 %. El análisis de regresión logística mostró un alto porcentaje de hiperglucemia (OR = 1,60, IC 95 % = 1,08-2,96; p = 0,02) y de síndrome metabólico (OR = 1,33, IC 95 % = 1,07-3,39; p = 0,02) en los portadores del alelo A después de ajustar las concentraciones de resistina, el sexo, el IMC y la edad. Conclusiones: el alelo A de la variante genética rs7139228 se asocia con mayores niveles de resistina, insulina basal, resistencia a la insulina y prevalencia de síndrome metabólico en sujetos obesos. (AU)


Background: despite the relationship of resistin with metabolic syndrome (MS), the relationship of the 5’UTR intron C/T variant single nucleotide ploymorphism (SNP) rs7139228 of the RETN gene with the presence of MS has not been evaluated. Objective: the objective of this study is to evaluate the influence of SNP rs7139228 of the RETN gene on circulating resistin levels, as well as on MS in obese subjects. Material and methods: a Caucasian population of 1003 obese subjects was enrolled. An anthropometric evaluation (weight, waist circumference, fat mass), evaluation of nutritional intake, biochemical study (glucose, insulin, C-reactive protein, lipid profile, insulin, HOMA-IR, resistin) and rs7139228 genotype was carried out. Results: genotype distribution was: 852 subjects with GG (84.9 %), 147 subjects with GA (14.7 %) and 4 subjects with AA (0.4 %). The allelic frequency was G (0.92) and A (0.08). Serum levels of resistin (delta: 1.7 ± 0.2 ng/ml; p = 0.01), insulin (delta: 4.2 ± 0.4 IU/L; p = 0.01) and HOMA-IR (delta: 1.9 ± 0.2 units; p = 0.03) were higher in patients carrying the A allele than in non-carriers. The overall prevalence of MS was 48.1 %. A logistic regression analysis showed a high percentage of hyperglycemia (OR = 1.60, 95 % CI = 1.08-2.96; p = 0.02) and metabolic syndrome (OR = 1.33, 95 % CI = 1.07-3.39, p = 0.02) in carriers of the A allele after adjusting for resistin levels, sex, BMI and age. Conclusions: the A allele of the genetic variant rs7139228 is associated with higher levels of resistin, basal insulin, insulin resistance, and prevalence of metabolic syndrome in obese subjects.

RESUMO

Antecedentes y objetivo El índice de masa triponderal (IMT) estimaría mejor que el índice de masa corporal (IMC) el exceso de adiposidad, manteniendo valores estables durante la infancia. Este trabajo pretende determinar la correlación del IMT con marcadores de riesgo metabólico y establecer valores del IMT que se relacionen con un aumento del riesgo metabólico. Material y métodos Estudio multicéntrico, observacional, transversal y prospectivo en menores de 14 años con obesidad. Variables: edad, sexo, estadio puberal, peso, talla, perímetro abdominal, IMC, IMT, glucosa e insulina basales, índice HOMA, presión arterial, perfil lipoproteico, transaminasas y ácido úrico. El IMC y el IMT se expresaron según los valores del estudio longitudinal de Barcelona. Se realizó análisis estadístico con el programa SPSS*. Resultados Se incluyeron 199 pacientes (50,3% varones), con una edad media de 11,08 (2,48) años e IMT de 19,68 (2,36) kg/m3. Se observó correlación del IMT con el perímetro abdominal (r = 0,571; p = 0), la insulina (r = 0,198; p = 0,005), el índice HOMA (r = 0,189; p = 0,008) y el c-HDL (r = −0,188; p = 0,008). El IMT > 20,15 kg/m3 se asoció a insulina ≥ 15 mUI/ml (p = 0,029) y el IMT > 20,36 kg/m3 a c-HDL < 40 mg/dl (p = 0,023). Conclusiones El IMT se correlacionó con el incremento del perímetro abdominal, la insulina y el índice HOMA, y la disminución del c-HDL. El IMT > 20 kg/m3 puede asociarse a elevación de la insulina y a descenso del c-HDL. Por ello, el IMT parece ser un parámetro útil en la valoración de los pacientes pediátricos con obesidad (AU)Background and objective


Triponderal mass index (TMI) would estimate excess adiposity better than body mass index (BMI), maintaining stable values during childhood. This work aims to determine the correlation between TMI and markers of metabolic risk as well as set values of TMI that are related to an increase of metabolic risk. Material and methods Multicenter, observational, cross-sectional and prospective study in children under 14 years of age with obesity. Variables: age, sex, pubertal stage, weight, height, abdominal circumference, BMI, TMI, basal glucose and insulin, HOMA index, blood pressure, lipoprotein profile, transaminases and uric acid. BMI and TMI were expressed according to the values of the Barcelona longitudinal study. Statistical analysis was performed with the SPSS* program. Results One hundred and ninety-nine patients (50.3% male), age 11.08 (2.48) years, TMI 19.68 (2.36) kg/m3. Correlation between TMI and abdominal circumference (r = 0.571; p = 0), insulin (r = 0.198; p = 0.005), HOMA index (r = 0.189; p = 0.008) and HDL-c (r = −0.188; p = 0.008) was observed. IMT > 20.15 kg/m3 was associated with insulin ≥ 15 mIU/ml (p = 0.029) and IMT > 20.36 kg/m3 with HDL-c < 40 mg/dl (p = 0.023). Conclusions TMI was correlated with increase of abdominal circumference, insulin and HOMA index and decrease of HDL-c. IMT > 20 kg/m3 can be associated with increased insulin and decreased HDL-c. Therefore, the IMT seems to be a useful parameter in the assessment of pediatric patients with obesity (AU)

RESUMO

Objetivo El objetivo de este trabajo es evaluar el efecto de la semaglutida subcutánea sobre los biomarcadores de la enfermedad metabólica hepática (MAFLD), a saber, el índice de esteatosis hepática (HSI) y el índice de fibrosis-4 (FIB-4), a las 24semanas en pacientes ambulatorios atendidos en los servicios de Medicina Interna. Métodos En este estudio se analizaron pacientes de un registro de cohortes en curso, multicéntrico, prospectivo, pre-post y no controlado que inscribe a pacientes únicos y consecutivos con diabetes tipo2 tratados con semaglutida subcutánea. La esteatosis/fibrosis se determinó mediante HSI (<30 descartada, >36 esteatosis) y FIB-4 (<1,3 descartada, >2,67 fibrosis), respectivamente. Resultados La muestra incluyó 213 pacientes (46,9% mujeres) con una mediana de edad de 64 (±19) años. El índice de masa corporal y el peso basales medios fueron de 36,1 (±8,4) kg/m2 y 98 (±26,9) kg, respectivamente. El 99,9% presentaba valores de HSI indicativos de esteatosis, con un HSI medio de 47,9 (±8,2). Además, el 10,8% presentaba fibrosis (FIB-4 >2,67) y el 42,72% tenía valores en rangos intermedios (FIB-4 1,3-2,67). A las 24 semanas se produjo una reducción significativa del HSI (−2,36 [IC95%: 1,83-2,9], p<0,00001) y del FIB-4 (−0,075 [IC95%: 0,015-0,14], p<0,016), relacionada principalmente con descensos del peso corporal, de los niveles de triglicéridos, de la resistencia a la insulina (estimada mediante el índice triglicéridos-glucosa) y de las enzimas hepáticas. Conclusiones Estos resultados muestran que la semaglutida subcutánea tuvo un efecto beneficioso sobre la esteatosis hepática que fue más allá del control de la glucosa. Sus efectos estaban relacionados principalmente con la pérdida de peso, la disminución de los biomarcadores y la mejora de la sensibilidad a la insulina. Para muchos pacientes, la detección precoz es esencial para mejorar los resultados de la MAFLD y puede permitir seleccionar las opciones terapéuticas más eficaces (AU)


Aim This work aims to assess the effect of weekly subcutaneous semaglutide on biomarkers of metabolic-associated fatty liver disease (MAFLD), namely the hepatic steatosis index (HSI) and the fibrosis-4 (FIB-4) index, at 24weeks in outpatients attended to in internal medicine departments. Methods This study analyzed patients in an ongoing, multicenter, prospective, pre-post, uncontrolled cohort registry that enrolls unique, consecutive patients with type2 diabetes treated with weekly subcutaneous semaglutide. Steatosis/fibrosis were determined by HSI (<30 ruled out, >36 steatosis) and FIB-4 (<1.3 ruled out, >2.67 fibrosis), respectively. Results The sample included 213 patients (46.9% women) with a median age of 64 (±19) years. The median baseline body mass index and weight were 36.1 (±8.4) kg/m2 and 98 (±26.9) kg, respectively. A total of 99.9% had HSI values indicating steatosis, with a mean HSI of 47.9 (±8.2). Additionally, 10.8% had fibrosis (FIB-4 >2.67) and 42.72% had values in intermediate ranges (FIB-4 1.3-2.67). At 24weeks, there was a significant reduction in HSI (−2.36 (95%CI: 1.83-2.9), p<0.00001) and FIB-4 (−0.075 (95%CI: 0.015-0.14), p<0.016), mainly related to declines in body weight, triglyceride levels, insulin resistance (estimated by the triglyceride-glucose index), and liver enzymes. Conclusion These results show that weekly subcutaneous semaglutide had a beneficial effect on liver steatosis that went beyond glucose control. Its effects were mainly related to weight loss, a decline in biomarkers, and improvements in insulin sensitivity. For many patients, early detection is essential for improving MAFLD outcomes and may allow for selecting the most efficient treatment options (AU)

RESUMO

Introducción: En México la diabetes mellitus tipo 2 (DM2) presenta niveles epidemiológicos, con una tasa de prevalencia del 9,12% y con los índices de sobrepeso y obesidad más altos del mundo. Para superar esta situación se deben crear estrategias enfocadas en la identificación de sujetos en riesgo. El índice triglicéridos y glucosa (TyG) fue creado para la detección de la resistencia a la insulina, y recientemente se ha empleado en la predicción de diabetes mellitus. El objetivo del presente estudio fue determinar el poder predictivo del índice TyG en una cohorte de la Ciudad de México.MétodosSe seleccionaron 3.195 pacientes de una cohorte de pacientes del área de crónico degenerativos de los Centros de Salud de los Servicios de Salud Pública de la Ciudad de México. Se evaluó la capacidad del índice TyG en la predicción de diabetes calculado como: ln (triglicéridos en ayunas [mg/dl]×glucosa en ayunas [mg/dl]/2) después de un seguimiento de al menos 4,5 años. Se determinó una prueba Chi-squared automated interaction detector analysis, que fue corroborada por una prueba ROC.ResultadosEl valor del índice de TyG fue significativamente mayor para los pacientes que desarrollar DM2. Los valores de área bajo la curva=0,934, intervalo de confianza (IC) 95%=0,924-0,924. Obteniendo un punto de corte de 9,45 en mujeres; en hombres: DM AUC=0.824, IC 95%=0,824-0,873 punto de corte 9.12.ConclusionesEl índice TyG es un buen marcador en la predicción de DM2 respaldado por la aplicación del algoritmo CHAID como herramienta útil para la predicción de DM2.

RESUMO

El virus de la hepatitis C (VHC) se ha asociado durante mucho tiempo a varias manifestaciones extrahepáticas, entre ellas el aumento del riesgo cardiovascular. La aparición de los antivirales de acción directa (AAD) ha permitido evaluar la posible reversión de estas manifestaciones tras un tratamiento exitoso. Así, muchos estudios han aportado datos significativos sobre el efecto positivo del tratamiento con AAD en la resistencia a la insulina, la diabetes mellitus de tipo 2, la enfermedad cardiovascular y la aterosclerosis. Por el contrario, los estudios han mostrado efectos perjudiciales sobre el metabolismo de los lípidos y resultados indeterminados respecto a la función renal y el metabolismo del ácido úrico. No obstante, a medida que un mayor número de pacientes logre una respuesta virológica sostenida, se estudiarán ampliamente los efectos de la erradicación del VHC sobre los procesos cardiometabólicos, lo que permitirá obtener conclusiones más fiables sobre el alcance de los resultados extrahepáticos.(AU)


Hepatitis C virus (HCV) has long been associated with several extrahepatic manifestations, including increased cardiovascular risk. The emergence of direct-acting antivirals (DAAs) has allowed us to evaluate the potential reversal of these manifestations after successful treatment. Therefore, many studies have provided significant takeaways regarding the positive effect of DAAs therapy on insulin resistance, type 2 diabetes mellitus, cardiovascular disease and atherosclerosis. In contrast, studies have shown detrimental effects on lipid metabolism and indeterminate results regarding renal function and uric acid metabolism. Nevertheless, as more and more patients achieve sustained virological response, the effects of HCV eradication on cardiometabolic processes will be extensively studied, allowing more reliable conclusions on the extent of extrahepatic outcomes.(AU)

RESUMO

La resistencia a la insulina se explica como un defecto en la unión de la insulina con su receptor y está asociada con numerosas enfermedades,como la obesidad o la diabetes tipo 2, entre otras. La resistencia a la insulina se ha relacionado con la deficiencia de vitaminas y minerales,especialmente de aquellos involucrados en el estrés oxidativo. La dieta mediterránea, una dieta basada en el Healthy Eating Index o la dietaDietary Approaches to Stop Hypertension (DASH) son patrones dietéticos que se han asociado con un menor riesgo de presentar resistencia a lainsulina en edad infantil. Por tanto, una dieta rica en vitaminas y minerales antioxidantes, fibra, calcio y ácidos grasos poliinsaturados y baja enazucares libres, sodio y ácidos grasos saturados puede disminuir el riesgo de presentar resistencia a la insulina en este grupo de edad. Además,otros factores nutricionales, como evitar la comida rápida, cenar en familia, no comer mientras se ve la televisión o el consumo regular de undesayuno suficiente y saludable son hábitos que parecen estar relacionados con menor riesgo de presentar resistencia a la insulina. Por tanto,es importante establecer hábitos alimentarios diarios equilibrados para prevenir y tratar la resistencia a la insulina en escolares y adolescentes. (AU)


Insulin resistance is described as a defect in the binding of insulin to its receptor and is associated with several diseases, including obesity andtype 2 diabetes. Insulin resistance has been linked to vitamin and mineral deficiencies, especially those involved in oxidative stress. The Mediterranean diet, a diet based on the Healthy Eating Index or the Dietary Approaches to Stop Hypertension (DASH) diet are dietary patterns that havebeen associated with a lower risk of developing insulin resistance in children. Therefore, a diet rich in antioxidant vitamins and minerals, fiber,calcium, and polyunsaturated fatty acids and low in free sugars, sodium and saturated fatty acids may decrease the risk of insulin resistancein this age group. In addition, other nutritional factors, such as avoiding fast food, eating dinner with the family, not eating while watching TV oreating a sufficient and healthy breakfast on a regular basis seem to be associated with a lower risk of insulin resistance. Therefore, it is importantto establish balanced daily eating habits to prevent and treat insulin resistance in schoolchildren and adolescents. (AU)

RESUMO

La infección crónica por el virus de la hepatitis C (VHC) está asociada con la resistencia a la insulina y la diabetes tipo 2. El objetivo general de este estudio fue evaluar los efectos del sofosbuvir sobre la resistencia a la insulina inducida por el VHC. Para ello, se realizó un estudio clínico que incluyó 42 pacientes con VHC resistentes a la insulina, que fueron tratados con diferentes regímenes antivirales basados en sofosbuvir. Asimismo, se utilizó una línea de hepatocitos humanos que expresan un replicón del VHC de manera estable para determinar los mecanismos moleculares implicados en la acción de la insulina regulada por sofosbuvir. Todos los pacientes alcanzaron una respuesta virológica sostenida después del tratamiento con sofosbuvir y se observó una reducción significativa en los marcadores de daño hepático, así como en el estadio de fibrosis. El índice de resistencia a la insulina (HOMA) mejoró significativamente a lo largo del estudio. A nivel molecular, el tratamiento con sofosbuvir mejoró la activación de la cascada de señalización de la insulina tras la estimulación con dicha hormona en los hepatocitos con VHC, y, en consecuencia, revirtió la expresión elevada de genes gluconeogénicos, el aumento de la producción de glucosa y la deficiencia de la síntesis de glucógeno en estas células. En conclusión, estos resultados sugieren que el sofosbuvir mejora la respuesta deficiente a la insulina originada por la infección del VHC, proporcionando novedosas evidencias en cuanto a los mecanismos moleculares implicados en la sensibilización a la insulina inducida por este tratamiento. (AU)


Chronic hepatitis C virus (HCV) infection is associated with insulin resistance and type 2 diabetes. The overall aim of this study was to evaluate the effects of sofosbuvir (SOF) on HCV-induced insulin resistance. Clinical parameters were recorded and insulin resistance index (HOMA) calculated from 42 insulin-resistant HCV-patients who underwent SOF-based regimens, at baseline, at the end of treatment (EoT), and at one year after the EoT. Likewise, Huh7 cells expressing full-length HCV replicons were used to elucidate the molecular mechanisms involved in insulin action regulated by SOF. All patients reached a sustained virological response after SOF treatment and, as expected, a significant reduction in liver damage markers and fibrosis stage was observed at the EoT that remained one year later. HOMA significantly improved throughout the study time period. Besides, an increase of total cholesterol, low-density lipoprotein cholesterol and apolipoprotein B levels were maintained over time after the EoT. At the molecular level, SOF treatment improved the activation of the insulin signalling cascade after stimulation with the hormone in HCV-hepatocytes and, accordingly, reversed the elevated expression of gluconeogenic genes, the increased glucose production and the impairment of glycogen synthesis induced by HCV. Furthermore, SOF challenge induced an increase of insulin receptor substrate 1 (IRS1) content parallel to a reduction in its serine phosphorylation in HCV-hepatocytes. These results provide novel evidence about the molecular mechanisms involved in the hepatic insulin sensitization induced by SOF treatment involving the recovery of IRS1 protein levels as a hallmark of SOF effects.

RESUMO

Introduction: metabolic syndrome (MetS) can have a bidirectional effect on emotional and restrained eating. Objectives: our aims are to find interrelations between MetS and emotional eating, restrained eating, additionally with depression. Methods: cross-sectional study. Participants aged between 18 and 63, and mostly were obese (n = 200). Eating Attitudes Test (EAT-26), Beck Depression Inventory (BDI) and Dutch Eating Behavior Questionnaire (DEBQ) were used to find associations between eating patterns and metabolic syndrome. Results: our study ensured evidences for physiological relations between restrained and emotional eating with MetS. Biochemical parameters showed that restrained eaters were less insulin resistant and participants with MetS had higher emotional eating and lower restrained eating. Besides, restrained eaters had lower triglyceride, homeostasis model assessment-insulin resistance (HOMA-IR), fasting insulin, blood glucose, and higher high-density lipoprotein cholesterol (HDL-C) levels; and emotional eating was parallel with fasting insulin level and HOMA-IR. Conclusions: MetS had strong associations with eating behaviors as restrained, emotional and external. In line with the findings of the study, additionally, women were more susceptible to MetS than men were. In the regulation of restrictive, emotional and external eating behaviors, dietitians and psychology experts should be in cooperation to treat disordered eating patterns. (AU)


Introducción: el síndrome metabólico (MetS) puede tener un efecto bidireccional sobre la alimentación emocional y restrictiva. Objetivos: nuestro objetivo es encontrar interacciones entre el MetS y la alimentación emocional y la alimentación restrictiva, sumado a la depresión. Métodos: se trata de un estudio transversal. un grupo de participantes de entre 18 y 63 años, en su mayoría obesos (n = 200). Para encontrar asociaciones entre los patrones de alimentación y el síndrome metabólico se utilizaron el Test de Actitudes Alimentarias (EAT-26), el Inventario de Depresión de Beck (BDI) y el Cuestionario Holandés de Comportamiento Alimentario (DEBQ). Resultados: nuestro estudio mostró evidencias de relaciones fisiológicas entre la alimentación restrictiva y emocional con el MetS. Los parámetros bioquímicos reflejaron que aquellos que comían contenidamente eran menos resistentes a la insulina y los participantes con MetS presentaban una mayor alimentación emocional y una menor restricción alimenticia. Además, los que comían contenidamente tenían niveles más bajos de triglicéridos, HOMA-IR, insulina en ayunas y glucosa en sangre, frente a niveles más altos de HDL-C. Asimismo, la alimentación emocional reflejó una relación paralela con el nivel de insulina en ayunas y HOMA-IR. Conclusiones se evidenció una notable asociación entre el MetS y los comportamientos alimenticios restrictivos, emocionales y externos. De acuerdo con los hallazgos del estudio, además, las mujeres eran más susceptibles al MetS que los hombres. En la regulación de las conductas alimenticias restrictivas, emocionales y externas, los dietistas y los expertos en psicología deben coadyuvar para tratar patrones de desórdenes alimenticios. (AU)

RESUMO

Introducción: cuando los tejidos periféricos tienen una incapacidad para responder a la acción de la insulina se denomina resistencia a la insulina (RI). Existen diferentes métodos para la identificación de la RI; uno de estos es el índice HOMA-IR, que utiliza los parámetros de laboratorio, glucosa e insulina en ayunas. El índice triglicéridos y glucosa (TyG) presenta la ventaja de solo necesitar análisis de laboratorio de rutina. Objetivo: evaluación de la distribución de los índices HOMA-IR y TyG en la población, así como determinar la capacidad predictiva del índice HOMA-IR utilizando el TyG como prueba diagnóstica para la RI. Materiales y métodos: estudio analítico transversal con 1686 participantes de 18 a 21 años del estado de San Luis Potosí. Se tomaron variables antropométricas de peso y talla y se cuantificó la concentración de glucosa, insulina y triglicéridos en ayuno. Además, se realizó un cuestionario para conocer los antecedentes heredofamiliares y la presencia de enfermedades no transmisibles (ENT). Para la comparación entre mujeres y hombres se realizó una prueba de la t de Student y se realizaron curvas operador receptor (COR) para determinar los valores de corte del HOMA-IR. (AU)


Introduction: when peripheral tissues don't respond well to insulin action, it is defined as insulin resistance (IR). Many methods and indices are available for the estimation of IR, among them the homeostasis model assessment of insulin resistance (HOMA-IR) involves fasting plasma glucose and insulin. Nevertheless, the TyG index has a methodological advantage over the HOMA-IR because it requires only measurements provided by routine laboratory tests. Aim: distribution asessment of the HOMA-IR and TyG indexes in the sample. Also, to determine the predictive capacity of HOMA-IR, using TyG cutoff point as IR-positive diagnostic test. Materials and methods: a cross-sectional analytical study with 1686 participants aged 18 to 21 years from the state of San Luis Potosí, Mexico. Anthropometric assessment involves variables of weight and height. Fasting glucose, insulin and triglyceride concentrations were quantified. In addition, a questionnaire was carried out to know the hereditary family history and the presence of noncommunicable diseases (NCDs). Student's t-test was used to assess the differences in mean statistics between males and females. A receiver operating characteristic (ROC) curve was applied to examine the potential of HOMA-IR to identify IR. (AU)
