RESUMO

The role of ADIPOQ gene variants on metabolic improvements after weight change secondary to different hypocaloric diets remained unclear. We evaluate the effect of rs3774261 of ADIPOQ gene polymorphism on biochemical improvements and weight change after high polyunsaturated fat hypocaloric diet with a Mediterranean dietary pattern for 12 weeks. A population of 361 obese subjects was enrolled in an intervention trial with a calorie restriction of 500 calories over the usual intake and 45.7% of carbohydrates, 34.4% of fats, and 19.9% of proteins. The percentages of different fats was; 21.8% of monounsaturated fats, 55.5% of saturated fats, and 22.7% of polyunsaturated fats. Before and after intervention, an anthropometric study, an evaluation of nutritional intake and a biochemical evaluation were realized. All patients lost weight regardless of genotype and diet used. After 12 weeks with a similar improvement in weight loss (AA vs. AG vs. GG); total cholesterol (delta: -28.1 ± 2.1 mg/dL vs. -14.2 ± 4.1 mg/dL vs. -11.0 ± 3.9 mg/dL; p = 0.02), LDL cholesterol (delta: -17.1 ± 2.1 mg/dL vs. -6.1 ± 1.9 mg/dL vs. -6.0 ± 2.3 mg/dL; p = 0.01), triglyceride levels (delta: -35.0 ± 3.6 mg/dL vs. 10.1 ± 3.2 mg/dL vs. -9.7 ± 3.1 mg/dL; p = 0.02), C reactive protein (CRP) (delta: -2.3 ± 0.1 mg/dL vs. -0.2 ± 0.1 mg/dL vs. -0.2 ± 0.1 mg/dL; p = 0.02), serum adiponectin (delta: 11.6 ± 2.9 ng/dL vs. 2.1 ± 1.3 ng/dL vs. 3.3 ± 1.1 ng/dL; p = 0.02) and adiponectin/leptin ratio (delta: 1.5 ± 0.1 ng/dL vs. 0.3 ± 0.2 ng/dL vs. 0.4 ± 0.3 ng/dL; p = 0.03), improved only in AA group. AA genotype of ADIPOQ variant (rs3774261) is related with a significant increase in serum levels of adiponectin and ratio adiponectin/leptin and decrease on lipid profile and C-reactive protein (CRP).

RESUMO

OBJETIVOS: en la práctica clínica habitual existen multitud de situaciones y patologías que pueden interrumpir la digestión y la absorción intestinal, cursando con desnutrición y requiriendo el uso de suplementos orales nutricionales (SON). El objetivo de nuestro estudio fue evaluar, en el contexto de la vida real, el uso de un SON basado en péptidos, y el cumplimiento con el mismo, en pacientes adultos desnutridos con compromiso intestinal tras más de 14 días de nutrición parenteral. MATERIAL Y MÉTODOS: el estudio se realizó en 44 pacientes desnutridos que requirieron nutrición parenteral total al menos 14 días, sin utilización de la vía oral durante el ingreso hospitalario. A todos los pacientes se les administró de manera ambulatoria 1 brik al día de Vital 1.5(R) para su consumo durante 12 semanas. Al inicio del tratamiento y tras el periodo de intervención se les recogieron las variables siguientes: peso, talla, índice de masa corporal (IMC), test de valoración subjetiva global, bioquímica nutricional, encuesta nutricional, efectos adversos generados por la fórmula y cumplimentación. RESULTADOS: se incluyeron 44 pacientes con una edad media de 70,4 ± 10,4 años (20 mujeres/24 hombres). Tras la intervención aumentaron el IMC (0,51 ± 0,1 kg/m2; p = 0,02), el peso (1,4 ± 0,3 kg; p = 0,03), la prealbúmina (3,5 ± 4,1 mg/dl; p = 0,01), la albúmina (1,3 ± 0,1 mg/dl; p = 0,03) y la transferrina (71,5 ± 24,1 mg/dl; p = 0,02). La toma del SON represento a los 3 meses un 14,4 % del aporte calórico total de la dieta, un 17,5 % de los hidratos de carbono, un 12,9 % de las proteínas y un 12,3 % de las grasas. La cumplimentación media del grupo fue del 87,7 ± 7,2 % de las tomas prescritas. En relacion a la situacion nutricional, a la entrada del estudio un 52,3 % (n = 23) de los pacientes presentaban en el test de valoración subjetiva global la categoría B (malnutrición moderada o riesgo nutricional) y un 47,7 % (n = 21) la categoría C (desnutrición severa). Tras la intervención, un 75 % de los pacientes presentaban la categoría A (buena situación nutricional (n = 33), un 13,6 % (n = 6) de los pacientes presentaban la categoría B y un 11,4 % (n = 5) la categoría C. CONCLUSIONES: la utilización de un suplemento peptídico con triglicéridos de cadena corta en pacientes ambulatorios tras haber recibido una nutrición parenteral total muestra un efecto beneficioso sobre los parametros bioquímicos y antropométricos, y la situación nutricional, con una alta cumplimentación y buena tolerancia


OBJECTIVES: in routine clinical practice many disorders are found that can disrupt the sequence of reactions in digestion and absorption, leading to malnutrition and requiring the use of oral nutritional supplements (ONS). The objective of our study was to evaluate in a real world setting the use of and compliance with a peptide-based ONS in malnourished adult patients with intestinal compromise after more than 14 days of parenteral nutrition. MATERIAL AND METHODS: the study was carried out in 44 malnourished patients who required total parenteral nutrition for at least 14 days without using the oral route during their hospital stay. All patients were administered, on an outpatient basis, 1 brick per day of Vital 1.5(R) for 12 weeks. At the beginning of treatment and after the intervention period evaluated, the following variables were collected: weight, height, body mass index (BMI), global subjective assessment test, nutritional biochemistry, 3-day nutritional survey, adverse effects generated by the formula, and completion rate. RESULTS: 44 patients were enrolled. Mean age was 70.4 ± 10.4 years (20 women & 24 men). After the intervention the following parameters had increased: BMI (0.51 ± 0.1 kg/m2; p = 0.02), weight (1.4 ± 0.3 kg; p = 0.03), prealbumin (3.5 ± 4.1 mg/dl; p = 0.01), albumin (1.3 ± 0.1 mg/dl; p = 0.03), and transferrin (71.5 ± 24.1 mg/dl; p = 0.02). Dietary intake of the ONS represented 14.4 % of the diet's total caloric intake at 3 months, 17.5 % of carbohydrates, 12.9 % of proteins, and 12.3 % of fats. Mean compliance was 87.7 ± 7.2 % of the prescribed intakes. In relation to the nutritional situation, at the beginning of the study, 52.3 % (n = 23) of patients were in the global subjective assessment test in category B (moderate malnutrition or nutritional risk), and 47.7 % (n = 21) in category C (severe malnutrition). After the intervention, 75 % of patients were in category A (n = 33), 13.6 % (n = 6) in category B, and 11.4 % (n = 5) in category C. CONCLUSIONS: the use of a peptide-based ONS with short-chain triglycerides in outpatients showed a beneficial effect on biochemical and anthropometric parameters, and improved the nutritional status of patients with high compliance and good tolerance rates

RESUMO

BACKGROUND: the role of ADIPOQ gene variants on metabolic changes after weight loss secondary to different hypocaloric diets remains unclear and poorly investigated. OBJECTIVE: we evaluated the effect of polymorphism rs266729 of ADIPOQ gene on biochemical changes and weight loss after a high-protein/ low-carbohydrate diet vs a standard severe hypocaloric diet during 9 months. MATERIAL AND METHODS: a population of 269 obese patients was enrolled in a randomized intervention trial for 9 months with two diets. Diet HP (high protein) was 33 % of carbohydrates (86.1 g/day), 33 % of fat (39.0 g/day), and 34 % of proteins (88.6 g/day). Diet S (standard) was 1093 cal/day, 53 % carbohydrates (144.3 g/day), 27 % fats (32.6 g), and 20 % proteins (55.6 g/day). Before and after the intervention an anthropometric evaluation, an assessment of nutritional intake, and a biochemical analysis were carried out. RESULTS: all patients lost weight regardless of genotype and diet. After the intervention with a high protein hypocaloric diet (diet HP) only subjects with CC genotype showed significant improvement in cholesterol (14.4 ± 1.8 md/dL vs -5.0 ± 1.9 mg/dL; p = 0.02), LDL-cholesterol (14.4 ± 1.9 mg/dL vs -5.1 ± 1.8 mg/dL; p = 0.01), insulin (-4.1 ± 0.3 mU/L vs -2.0 ± 0.6 mU/L; p = 0.02), HOMA-IR (-1.4 ± 0.2 units vs -0.5 ± 0.3 units; p = 0.02) and adiponectin (10.2 ± 1.4 ng/dL vs 3.1 ± 1.1 ng/dL; p = 0.01) levels. After the second dietary strategy with a standard hypocaloric diet (diet S) only subjects with CC genotype showed significant improvement in total cholesterol (CC vs CG + GG) (-17.1 ± 1.9 md/dL vs -5.3 ± 1.3 mg/dL; p = 0.02), LDL-cholesterol (-12.3 ± 1.9 mg/dL vs -8.0 ± 1.2 mg/dL; p = 0.01), insulin (-4.0 ± 0.9 mU/L vs -1.3 ± 0.5 mU/L; p = 0.02), HOMA-IR (-1.2 ± 0.1 units vs -0.6 ± 0.2 units; p = 0.02), and adiponectin (11.1 ± 2.7 ng/dL vs 3.3 ± 1.2 ng/dL; p = 0.02) levels. CONCLUSION: non G-allele carriers showed a better response of LDL-cholesterol, HOMA-IR, insulin, and adiponectin levels than G-allele carriers before weight loss with both diets


ANTECEDENTES: el papel de las variantes del gen ADIPOQ en los cambios metabólicos después de la pérdida de peso secundaria a diferentes dietas hipocalóricas sigue sin estar claro y es un área poco investigada. OBJETIVO: evaluamos el efecto del polimorfismo rs266729 del gen ADIPOQ sobre los cambios bioquímicos y la pérdida de peso después de una dieta con alto contenido en proteínas y baja en carbohidratos frente a una dieta hipocalórica severa estándar durante 9 meses. MATERIAL Y MÉTODOS: se reclutó una muestra de 269 pacientes obesos en un ensayo de intervención aleatorizado de 9 meses con dos dietas. La dieta HP (alta en proteínas) tenía la siguiente composicion: 33 % de carbohidratos (86,1 g/día), 33 % de grasas (39,0 g/día) y 34 % de proteínas (88,6 g/día). La dieta S (estándar), de 1093 cal/día, tenía 53 % de carbohidratos (144,3 g/día), 27 % de grasas (32,6 g) y 20 % de proteínas (55,6 g/día). Antes y después de la intervención se realizaron una evaluación antropométrica, una valoración de la ingesta nutricional y un análisis bioquímico. RESULTADOS: todos los pacientes bajaron de peso independientemente del genotipo y la dieta utilizada. Después de la intervención con la dieta HP, solo los sujetos con genotipo CC mostraron una mejoría significativa de los niveles de colesterol (14,4 ± 1,8 mg/dl vs. -5,0 ± 1,9 mg/dl; p = 0,02), colesterol-LDL (14,4 ± 1,9 mg/dl frente a -5,1 ± 1,8 mg/dl; p = 0,01), insulina (-4,1 ± 0,3 mU/L frente a -2,0 ± 0,6 mU/L; p = 0,02), HOMA-IR (-1,4 ± 0,2 unidades frente a -0,5 ± 0,3 unidades; p = 0,02) y adiponectina (10,2±1,4 ng/dl frente a 3,1 ± 1,1 ng/dl; p = 0,01). Después de la segunda estrategia dietética con una dieta hipocalórica estándar (dieta S), solo los sujetos con genotipo CC mostraron una mejora significativa de los niveles de colesterol total (CC vs. CG + GG) (-17,1 ± 1,9 mg/dl vs. -5,3 ± 1,3 mg/dl; p = 0,02), colesterol-LDL (-12,3 ± 1,9 mg/dl frente a -8,0 ± 1,2 mg/dl; p = 0,01), insulina (-4,0 ± 0,9 mU/L frente a -1,3 ± 0,5 mU/L; p = 0,02), HOMA-IR (-1,2 ± 0,1 unidades frente a -0,6 ± 0,2 unidades; p = 0,02) y adiponectina (11,1 ± 2,7 ng/dl frente a 3,3 ± 1,2 ng/dl; p = 0,02). CONCLUSIÓN: los no portadores del alelo G mostraron una mejor respuesta de los niveles de colesterol-LDL, HOMA-IR, insulina y adiponectina que los portadores del alelo G antes de la pérdida de peso con ambas dietas

RESUMO

PURPOSE: The COVID-19 pandemic could exacerbate the risk factors for weight gain in patients with previous bariatric surgery. The aim of this study was to evaluate factors related to weight gain during lockdown in patients with a sleeve gastrectomy. MATERIALS AND METHODS: A group of 48 obese subjects with previous bariatric surgery was enrolled. After a 7-week confinement, a telephone interview was conducted. In this phone call, self-reported body weight gain and different factors were recorded. In order to obtain the basal and pre-surgical data, biochemical and anthropometric parameters were recorded from electronic medical record. RESULTS: The mean age was 45.3±8.0 years (range: 23-61) and the mean body mass index (BMI) was 32.5±7.5 kg/m2 (range: 28.6-34.2). Gender distribution was 38 females (79.2%) and 10 males (20.8%). The increase in self-reported body weight was 3.8±2.1 kg during the 7 weeks of confinement. And the self-reported body weight gain was lower in subjects with regular exercise (4.6±0.9 vs 1.1±0.3 kg; p=0.02). The number of face-to-face visits to the nutrition office that did not attend was 0.61±0.81 (range: 0-4) per patient. In the multiple regression analysis with self-reported body weight gain as a dependent variable, the physical activity (minutes/week) remained as a protective factor with a beta coefficient of -0.09 (95% CI: -0.001 to 0.016; p=0.03) and number of face-to-face appointments in the nutrition consultation missed as a risk factor with a beta coefficient of 9.65 (95% CI: 1.17-18.12; p=0.03). CONCLUSIONS: The increase in self-reported body weight is associated with a decrease in physical activity and the loss of face-to-face visits to the Nutrition Unit.

RESUMO

OBJECTIVE: the COVID-19 pandemic, by restricting population mobility, may exacerbate the risk factors for weight gain associated with physical inactivity and increased consumption of calorie-dense foods. The aim of this cross-sectional study was to evaluate the risk factors related to self-reported body weight gain among obese subjects. METHODS: the study involved a population of 284 adult obese subjects. After a 7-week confinement period starting on March 17, a telephone interview (May 4 through 7) was conducted. In this phone call, self-reported body weight gain and a number of factors were recorded. In order to obtain the baseline data of this population, biochemical and anthropometric parameters were collected from electronic medical records. RESULTS: mean age was 60.4 ± 10.8 years (range: 23-71) and mean body mass index (BMI) was 35.4 ± 4.7 kg/m2 (range: 30.6-41.2). Gender distribution was 211 females (74.3 %) and 73 males (25.7 %). Self-reported body weight gain was 1.62 ± 0.2 kg. Among patients who reported doing a lot of exercise self-reported body weight gain was lower (1.62 ± 0.2 vs 1.12 ± 0.3 kg; p = 0.02). Regarding eating habits, patients recognized snacking in 17 % of the sample. Patients who reported snacking had higher self-reported body weight gains (2.60 ± 0.36 vs 1.30 ± 0.17 kg; p = 0.001). The remaining variables did not influence self-reported body weight gain. In the multiple regression analysis with self-reported body weight gain as dependent variable, adjusted for age, sex, and physical activity, the snaking habit remained a risk factor: beta = 1.21 (95 % CI: 1.11-2.13; p = 0.01). CONCLUSIONS: the lockdown decreed during SARS-CoV-2 pandemic has produced an increase in self-reported body weight among obese subjects, which was related to the habit of taking snacks


OBJETIVO: la pandemia de COVID-19, al restringir la movilidad de la población, podría exacerbar los factores de riesgo del aumento de peso asociados a la inactividad física y un mayor consumo de alimentos ricos en calorías. El objetivo de este estudio transversal fue evaluar los factores de riesgo relacionados con el aumento de peso corporal autoinformado entre sujetos obesos. MÉTODOS: el estudio incluyó una muestra de 284 sujetos obesos adultos. Después de un período de reclusión de 7 semanas a partir del 17 de marzo, se realizó una entrevista telefónica (del 4 al 7 de mayo). En esta llamada telefónica se registraron el aumento de peso corporal autoinformado y diferentes factores asociados. Para obtener los datos basales de esta población, se registraron parámetros bioquímicos y antropométricos a partir de la historia clínica electrónica. RESULTADOS: la edad media fue de 60,4 ± 10,8 años (rango: 23-71) y el índice de masa corporal (IMC) medio de 35,4 ± 4,7 kg /m2 (rango: 30,6-41,2). La distribución por géneros fue de 211 mujeres (74,3 %) y 73 hombres (25,7 %). El aumento de peso corporal autoinformado fue de 1,62 ± 0,2 kg. Los pacientes que reconocieron que hacían mucho ejercicio informaron de que la ganancia de peso corporal había sido menor (1,62 ± 0,2 vs 1,12 ± 0,3 kg; p = 0,02). En cuanto a los hábitos alimentarios, los pacientes reconocieron practicar el picoteo en el 17 % de la muestra. Los pacientes que reconocieron picar entre horas presentaron una mayor ganancia de peso corporal autoinformada (2,60 ± 0,36 vs 1,30 ± 0,17 kg; p = 0,001). Las demás variables no influyeron en el aumento de peso corporal autoinformado. En el análisis de regresión múltiple, con la ganancia de peso corporal autoinformada como variable dependiente y ajuste de edad, sexo y actividad física, el hábito del picoteo permaneció como factor de riesgo: beta = 1,21 (IC 95 %: 1,11-2,13; p = 0,01). CONCLUSIONES: el encierro decretado durante la pandemia por el SARS-CoV-2 ha producido un aumento del peso corporal autoinformado en los sujetos obesos y este se ha relacionado con el hábito de picar entre horas

RESUMO

BACKGROUND: The role of adiponectin (ADIPOQ) polymorphisms in weight loss and serum lipid changes following different dietary interventions remain unclear. The Mediterranean dietary pattern has been associated with improved cardiovascular risk factors in different studies. OBJECTIVE: Our aim was to analyze the effects of a hypocaloric diet with a Mediterranean dietary pattern on the metabolic response and adiposity parameters, taking into account the 712 G/A rs3774261 polymorphisms in ADIPOQ. DESIGN: A population of 135 obese patients was enrolled. Anthropometric and serum parameters (lipid profile, insulin, homeostasis model assessment for insulin resistance [HOMA-IR], glucose, C-reactive protein [CRP], adiponectin, resistin, and leptin levels) were measured before and after the dietary intervention (12 weeks). All of the patients were genotyped for the rs3774261 polymorphism. RESULTS: The genotype distribution of this population was 36 patients with AA (26.7%), 68 patients with AG (50.4%), and 31 patients with GG (22.9%). After the dietary intervention and in both genotypes, BMI, weight, fat mass, systolic blood pressure, waist circumference, glucose, insulin, HOMA-IR, and leptin levels all decreased. After the dietary intervention with secondary weight loss and in non-G-allele carriers (AA vs. AG+GG), total cholesterol (Δ = -15.7 ± 3.9 vs. -4.9 ± 2.9 mg/dL; p = 0.02), LDL cholesterol (Δ = -15.3 ± 3.8 vs. -1.7 ± 1.9 mg/dL; p = 0.01), triglyceride levels (Δ = -23.4 ± 5.6 vs. 2.3 ± 2.3 mg/dL; p = 0.01), and CRP (Δ = -1.1 ± 0.1 vs. -0.4 ± 0.2 mg/dL; p = 0.01) decreased. Adiponectin levels (Δ = 7.2 ± 2.1 vs. -0.4 ± 0.3 ng/dL; p = 0.02) increased. Notably, G-allele carriers did not show this improvement. CONCLUSION: Non-G-allele carriers of the ADIPOQ variant (rs3774261) showed significant improvement in serum levels of adiponectin, lipid profiles, and CRP in response to a hypocaloric diet with a Mediterranean dietary pattern.

RESUMO

ANTECEDENTES: Los receptores CB2R han sido etiquetados como los receptores endocanabinoides periféricos por excelencia, y regulan diferentes procesos inflamatorios. Las variantes del gen CB2R podrían desempeñar un papel en los cambios metabólicos después de la pérdida de peso con diferentes intervenciones. OBJETIVO: Evaluar el efecto de la variante genética (rs3123554) del gen CB2R en los cambios antropométricos y bioquímicos después de la pérdida de peso, secundaria a una dieta hipocalórica alta proteína/baja en hidratos de carbono vs. una dieta hipocalórica estándar durante 9 meses. DISEÑO: Doscientos sesenta y ocho sujetos obesos fueron asignados al azar a una de 2 dietas durante 9 meses, dieta HP (dieta hipocalórica alta en proteínas y baja en hidratos de carbono) y dieta S (dieta hipocalórica estándar en proteínas). Se evaluaron parámetros bioquímicos y antropométricos al basal, a los 3 y a los 9 meses. RESULTADOS: Un total de 94 pacientes (35,1%) tenían el genotipo GG y 174 (64,9%) sujetos tenían los genotipos siguientes; GA (115 pacientes, 42,9%) o AA (59 sujetos de estudio, 18,0%) (segundo grupo). Después de ambas dietas y en ambos genotipos, el índice de masa corporal (IMC), la masa grasa, el peso, la circunferencia de la cintura y la presión arterial sistólica mejoraron sin diferencias entre ambas dietas. Antes y después de ambas dietas hipocalóricas, el peso corporal, el IMC, la masa grasa y la circunferencia de la cintura fueron mayores en los portadores del alelo A. Después de ambas dietas (HP y S), la glucosa, los niveles de insulina, HOMA-IR, los triglicéridos, el colesterol total y el colesterol-LDL disminuyeron en portadores de alelos no A. Estos parámetros se mantuvieron sin cambios en los portadores de alelos A. Los niveles de leptina disminuyeron después de las dietas HP y S en ambos genotipos. CONCLUSIÓN: Los no portadores del alelo A mostraron una mejor respuesta del colesterol total, colesterol LDL, triglicéridos, glucosa, HOMA-IR y niveles de insulina que los portadores A con ambas dietas hipocalóricas y con la misma pérdida de peso


BACKGROUND: CB2R receptors has been referred to as the peripheral cannabinoid receptor isoform, and regulate inflammatory response in various settings. CB2R gene variants could play a role on metabolic changes after weight loss with different interventions. OBJECTIVE: To assess the effect of the genetic variant (rs3123554) of the CB2R gene on anthropometric and biochemical changes after weight loss secondary to a high protein/low carbohydrate diet vs. a standard low-calorie diet during 9 months. DESIGN: 268 obese subjects were randomly allocated to one of two diets for 9 months, Diet HP (high protein-low carbohydrate low-calorie diet) and Diet S (standard protein low-calorie diet). Biochemical and anthropometric parameters were measured at baseline and at 3 and 9 months. RESULTS: Ninety-four patients (35.1%) had genotype GG and 174 (64.9%) subjects had the following genotypes; GA (115 patients, 42.9%) or AA (59 study subjects, 18.0%) (second group). After both diets, body mass index (BMI), fat mass, weight, waist circumference, and systolic blood pressure improved in both genotypes with no difference between diets. Before and after both low-calorie diets, body weight, BMI, fat mass, and waist circumference were higher in A allele carriers than in non-A allele carriers. After both diets (HP and S), levels of glucose, insulin, HOMA-IR, triglycerides, total cholesterol, and LDL cholesterol decreased in non-A allele carriers. These parameters remained unchanged in A allele carriers. Leptin levels decreased after HP and S diets in both genotypes. CONCLUSION: Non-A allele carriers showed a better response of total cholesterol, LDL cholesterol, triglycerides, glucose, HOMA-IR, and insulin levels than allele A carriers with both low-calorie diets and with the same weight loss

RESUMO

INTRODUCCIÓN Y OBJETIVOS: los estudios de intervención que evalúan el efecto del rs16147 sobre la respuesta metabólica y el cambio de peso después de una intervención dietética son escasos. En este trabajo evaluamos el papel de la variante genética rs16147 en los efectos metabólicos que produce una dieta hipocalórica de patrón mediterráneo y alto contenido en omega-9. MATERIAL Y MÉTODOS: se reclutó una muestra de 363 sujetos obesos. En la visita basal, los pacientes se asignaron aleatoriamente, durante 12 semanas, a recibir una de dos dietas: dieta M, de patrón mediterráneo, o dieta C, hipocalórica estándar. En todos ellos se determinaron, en el momento basal y a las 12 semanas, una serie de variables bioquímicas y antropométricas, realizándose el genotipado de la variante rs16147. RESULTADOS: en todos los sujetos y con ambas dietas mejoraron los parámetros de adiposidad, tensión arterial y leptina circulante. En los sujetos obesos con el alelo menor (A), los niveles de insulina (GG vs. GA + AA) (-0,9 ± 1,1 UI/L vs. -4,4 ± 1,0 UI/L; p = 0,01) y HOMA-IR (-0,3 ± 0,1 unidades vs. -1,2 ± 0,3 unidades; p = 0,02) disminuyeron significativamente con la dieta M. Los sujetos portadores del alelo menor tras la dieta C mostraron una disminución significativa de los niveles de insulina basal (GG vs. GA + AA) (0,7 ± 0,3 UI/L vs. -2,2 ± 0,9 UI/L: p = 0,02) y HOMA-IR (-0,3 ± 0,2 unidades vs. -0,7 ± 0,1 unidades: p = 0,01). Esta disminución de los niveles de insulina circulante y HOMA-IR en los pacientes con alelo A fue significativamente superior con la dieta M que con la dieta S. CONCLUSIONES: el alelo A de la variante rs16147 se relaciona con una mejor respuesta metabólica, en términos de resistencia a la insulina e insulina basal secundaria a la pérdida de peso, a dos dietas hipocalóricas, siendo superior el efecto obtenido con una dieta de patrón mediterráneo


BACKGROUND AND AIMS: intervention studies that evaluate the effect of rs16147 on metabolic response and weight change after dietary intervention are scarce. We propose to evaluate the role of the rs16147 genetic variant in the metabolic effects produced by a hypocaloric Mediterranean-pattern diet with high content of omega-9. MATERIAL AND METHODS: a sample of 363 obese subjects was recruited. At the baseline visit the patients were randomly assigned to one of two hypocaloric diets for 12 weeks (diet M, Mediterranean pattern; diet C, standard hypocaloric). All patients, at baseline and at 12 weeks, had biochemical and anthropometric variables measured, and genotyping performed for the rs16147 variant. RESULTS: in all subjects, and with both diets, the parameters of adiposity, blood pressure, and circulating leptin improved. In obese subjects with allele (A) insulin levels (GG vs. GA + AA) (-0.9 ± 1.1 IU/L vs. -4.4 ± 1.0 IU/L; p = 0.01) and HOMA-IR (-0.3 ± 0.1 units vs. -1.2 ± 0.3 units; p = 0.02) decreased significantly with diet M. Subjects carrying the minor allele showed a significant decrease in basal insulin levels (GG vs. GA + AA) (0.7 ± 0.3 IU/L vs. -2.2 ± 0.9 IU/L: p = 0.02) and HOMA-IR (-0.3 ± 0.2 units vs. -0.7 ± 0.1 units: p = 0.01) after diet C. This decrease in circulating insulin and HOMA-IR levels in patients with allele A was significantly higher with diet M than with diet C. CONCLUSIONS: the A allele of the rs16147 variant produces a better metabolic response in terms of insulin resistance and basal insulin secondary to weight loss with two different hypocaloric diets in obese subjects, with improvement being higher with the Mediterranean diet

RESUMO

INTRODUCTION: the composition of snack foods likely influences the overall effect that snacking has on metabolism and obesity. The objective of the current study was to assess the responses to two different snacks, one of them supplemented with wakame and carobs, on cardiovascular risk factors, satiety, and subsequent food intake in obese subjects with metabolic syndrome. MATERIAL AND METHODS: forty patients were randomized in a clinical trial (NCT03420989, clinicaltrial.gov) to group I (enriched snack, n = 16) or group II (control snack, n = 16). At baseline and after 8 weeks biochemical parameters, dietary intakes, and nutritional status were assessed. The subjects also rated their feelings of satiety/hunger with a test meal. RESULTS: no differences were detected in anthropometric parameters between both snacks. Changes in other parameters were detected in patients with enriched snacks, with a significant decrease in LDL-cholesterol by 7.4 % (intervention snack, -8.9 ± 2.3 mg/dL vs control snack, -0.9 ± 3.3 mg/dL; p = 0.03), in total cholesterol by 5.8 % (intervention snack, -10.4 ± 2.9 mg/dL vs control snack, -1.4 ± 3.2 mg/dL; p = 0.02), and in resistin level by 15.9 % (intervention snack, -1.0 ± 0.2 mg/dL vs control snack, -0.1 ± 0.3 mg/dL: p = 0.03). After the test meal, satiety scores (after 20 min and 40 min) were higher than fasting levels in both groups. The same results were obtained with the 100-mm, 5-point visual satiety scale. CONCLUSION: our study indicates that a wakame- and carob-enriched snack induces a significant decrease in total cholesterol, LDL-cholesterol, and resistin levels when compared to a control snack, without effects on food consumption, other cardiovascular parameters, or anthropometric parameters


INTRODUCCIÓN: la composición de los "snacks" probablemente influya en el efecto que produce su consumo sobre los marcadores metabólicos y la obesidad. El objetivo del presente estudio fue evaluar las respuestas a dos snacks, uno de ellos suplementado con wakame y algarroba, sobre factores de riesgo cardiovascular, saciedad y posterior ingesta de alimentos, en sujetos obesos con síndrome metabólico. MATERIAL Y MÉTODOS: se aleatorizaron 40 pacientes en el ensayo clínico NCT03420989 (clinicaltrial.gov) para participar en el grupo I (snack enriquecido, n = 16) o el grupo II (snack de control, n = 16). Antes y después de 8 semanas se determinaron los parámetros bioquímicos, las ingestas dietéticas y el estado nutricional. A los sujetos también se les evaluó la saciedad y el apetito con una comida de prueba. RESULTADOS: no se detectaron diferencias en los parámetros antropométricos con ambos snacks. Se detectaron cambios en los parámetros bioquímicos de los pacientes que recibieron snacks enriquecidos, con una disminución significativa del colesterol-LDL del 7,4 % (snack de intervención, -8,9 ± 2,3 mg/dl vs. snack de control, -0,9 ± 3,3 mg/dl; p = 0,03), del colesterol total del 5,8 % (snack de intervención, -10,4 ± 2,9 mg/dl vs. snack de control, -1,4 ± 3,2 mg/dl; p = 0,02) y de los niveles de resistina del 15,9 % (snack de intervención, -1,0 ± 0,2 mg/dl vs. snack de control, -0,1 ± 0,3 mg/dl; p = 0,03). Después de la comida de prueba, las puntuaciones de saciedad (a los 20 min y 40 min) fueron más altas que el nivel de ayuno en ambos grupos. Los resultados fueron similares con la escala de saciedad visual de 5 puntos y 100 mm. CONCLUSIÓN: nuestro estudio muestra que un snack enriquecido con wakame y algarroba produce una disminución significativa de los niveles de colesterol total, colesterol-LDL y resistina frente a un snack de control, sin efectos sobre el consumo de alimentos, otros parámetros cardiovasculares y los parámetros antropométricos

RESUMO

Introduction: Objective: the aim of the current work was to evaluate the response time to a method of weight loss that includes dietary guidelines, physical exercise and emotional support. The response was defined as a loss of 10% of the baseline weight. Methods: data was obtained from the patients' record recruited in Promet Lipoinflamación, an observational study of real world data in obese or overweight patients treated with a multidisciplinary method and based initially on a very-low-calorie ketogenic (VLCK) diet. Weight loss rate was evaluated through a survival analysis Kaplan-Meier and related factors through Cox regression). Results: 6,369 subjects were included and 74.4% managed to reach a weight loss of 10% in a mean time of 57.64 days (IC 95%: 56.95-58.33). The factors associated with a greater probability of reaching a loss of 10% or more were male gender (RR: 1.37, p < 0.001), obesity types I, II and III vs. overweight (RR: 1.24, p < 0.001, 1.26, p < 0.001 and 1.22, p < 0.001, respectively) and young age vs. more than 55 years old (RR: 2.17, p < 0.001). Conclusion: Results obtained through real clinical practice show that the method produces fast and intense weight loss. Three out of four patients lost at least 10% of body weight in an average of 58 days.

RESUMO

BACKGROUND AND AIMS: The prevalence of the non-alcoholic fatty liver disease (NAFLD) in developed countries is up to 30% of the general population, and 50% of patients present type 2 diabetes mellitus (DM2). Fibrosis is the most important prognostic factor in NAFLD. The aim of this study was to search evidence for an early diagnosis of liver fibrosis in subjects with DM2 and to evaluate potential risk and protective factors. METHODS: This study was conducted among 160 diabetic patients with NAFLD proven biopsy. Anthropometric assessments, laboratory test, liver histological features and follow-up of a Mediterranean diet were evaluated. RESULTS: Diabetic patients with liver fibrosis showed a greater number of positive metabolic criteria than diabetic patients without liver fibrosis. Patients with hepatic fibrosis have a lower score on the PREDIMED test (9.0 (2.4) vs. 6.2 (2.3); p < 0.05). Diabetic patients with liver fibrosis showed higher glucose levels (delta: 10.1 (4.5) mg/dl), fasting insulin levels (delta: 3.1 (1.5) UI/L), HOMA-IR (delta: 2.1 (0.3) units) and HbA1c (delta: 0.6 (0.2)%). Non-invasive tests showed a higher score (non-alcoholic fatty liver disease fibrosis score and fibrosis-4) in liver fibrosis subjects than no liver fibrosis subjects. A logistic regression analysis adjusted by age, gender, HbA1c and body mass index showed independent significant direct association between liver fibrosis and homeostatic model assessment of insulin resistance as indicator of insulin resistance (odds ratio (OR) = 1.53: 95% confidence interval (CI): 1.1-2.2; p = 0.026) and inverse association with PREDIMED score as an indicator of adherence to Mediterranean diet (OR = 0.6; 95% CI: 0.4-0.8; p = 0.01). CONCLUSION: In patients with DM2, insulin resistance is an independent risk factor associated with liver fibrosis, and the adherence of a Mediterranean diet is a protective factor associated with absence of liver fibrosis.

RESUMO

BACKGROUND & AIMS: The risk allele (G) of rs10830963 in the melatonin receptor 1 B (MTNR1B) gene presents an association with biochemical parameters and obesity. We study the effect of this SNP on insulin resistance and weight loss secondary to two hypocaloric diets. METHODS: 270 obese subjects were randomly allocated during 9 months (Diet HP: a high protein/low carbohydrate vs. Diet S: a standard severe hypocaloric diets). Anthropometric parameters, fasting blood glucose, C-reactive protein (CRP), insulin concentration, insulin resistance (HOMA-IR), lipid profile and adipocytokines levels were measured. Genotype of MTNR1B gene polymorphism (rs10830963) was evaluated. RESULTS: All adiposity parameters, systolic blood pressure and leptin levels decreased in all subjects after both diets. This improvement of adiposity parameters was higher in non-G allele carriers than G allele carriers. After weight loss with Diet HP, (CC vs. CG + GG at 9 months); total cholesterol (delta: -9.9 ±â€¯2.4 mg/dl vs. -4.8 ±â€¯2.2 mg/dl:p < 0.05), LDL-cholesterol (delta: -8.3 ±â€¯1.9 mg/dl vs. -5.1 ±â€¯2.2 mg/dl: p < 0.05), insulin (delta: -4.7 ±â€¯0.8 UI/L vs. -0.9 ±â€¯1.0 UI/L: p < 0.05), triglycerides (delta: -17.7 ±â€¯3.9 mg/dl vs. -6.1 ±â€¯2.8 mg/dl: p < 0.05) and HOMA IR (delta: -0.8 ±â€¯0.2 units vs. -0.2 ±â€¯0.1 units: p < 0.05) improved only in no G allele carriers. After weight loss with Diet S in non G allele carriers, insulin levels (delta (CC vs. CG + GG): -3.4 ±â€¯0.6 UI/L vs. -1.2 ±â€¯0.4 UI/L: p < 0.05), triglycerides (delta: -29.2 ±â€¯3.4 mg/dl vs. -8.2 ±â€¯3.8 mg/dl: p < 0.05), HOMA-IR (delta (CC vs. CG + GG): -1.1 ±â€¯0.2 units vs. -0.1 ±â€¯0.1 units: p < 0.05), total cholesterol (delta: -15.9 ±â€¯7.4 mg/dl vs. -5.8 ±â€¯2.9 mg/dl:ns) and LDL-cholesterol (delta: -13.7 ±â€¯5.9 mg/dl vs. -6.0 ±â€¯2.9 mg/dl: ns) decreased, too. CONCLUSIONS: our study detected a relationship of rs10830963 variant of MTNR1B gene with adiposity changes, cholesterol changes and insulin resistance modification induced by two different hypocaloric during 9 months.

RESUMO

ANTECEDENTES Y OBJETIVOS: El alelo de riesgo (G) de la variante rs10830963 en el gen del receptor de melatonina 1 B (MTNR1B) se relaciona con la obesidad. En este trabajo evaluamos el efecto de este SNP sobre los factores de riesgo cardiovascular y la pérdida de peso secundaria a 2 dietas hipocalóricas. MÉTODOS: Trescientos sesenta y un sujetos obesos fueron asignados aleatoriamente durante 3 meses (dieta M: dieta hipocalórica alta en grasas monoinsaturadas vs. dieta P: dieta hipocalórica alta en grasas poliinsaturadas). Se midieron los parámetros antropométricos, glucemia en ayunas, proteína C reactiva, concentración de insulina, resistencia a la insulina (HOMA-IR), perfil de lípidos y los niveles de adipocitoquinas. Se evaluó el genotipo del polimorfismo del gen MTNR1B (rs10830963). RESULTADOS: Todos los parámetros antropométricos, la presión arterial sistólica y los niveles de leptina disminuyeron en todos los sujetos después de ambas dietas. Esta mejora de los parámetros antropométricos fue mayor en los no portadores del alelo G que en los portadores del alelo G. Tras la intervención con dieta M (CC vs. CG + GG), el colesterol total (delta: -10,4 ± 2,1 mg/dl vs. -6,4 ± 1,2 mg/dl: p < 0,05), colesterol LDL (delta: -7,1 ± 0,9 mg/dl vs. -2,8 ± 0,8 mg/dl: p < 0,05), insulina (delta: -3,0 ± 0.8 UI/l vs. -2,0 ± 1,0 UI/l: p < 0,05) y HOMA IR (delta: -3,4 ± 1,0 unidades vs. -2,9 ± 0,9 unidades: p < 0,05) mejoraron en los no portadores del alelo G. Tras la dieta P, en el grupo de sujetos sin alelo G, los niveles de insulina (delta: -2,9 ± 1,0 UI/l vs. -0,6 ± 0,2 UI/l: p < 0,05) y HOMA-IR (delta [CC vs. CG + GG]: -0,8 ± 0,2 unidades vs. -0,4 ± 0,3 unidades: p < 0,05) también disminuyeron. CONCLUSIONES: Nuestro estudio detectó una relación de la variante rs10830963 de MTNR1B con la pérdida de peso corporal y la modificación de la resistencia a la insulina inducida por 2 dietas hipocalóricas diferentes. Solo la dieta hipocalórica enriquecida en grasa monoinsaturada y los no portadores del alelo G mostraron un efecto significativo sobre las lipoproteínas


BACKGROUND & AIMS: The risk allele (G) of rs10830963 in the melatonin receptor 1 B (MTNR1B) gene presents an association with obesity. We study the effect of this SNP on cardiovascular risk factors and weight loss secondary to 2hypocaloric diets. Methods: 361 obese subjects were randomly allocated during 3 months (Diet M - high monounsaturated fat hypocaloric diet vs. Diet P - high polyunsaturated fat hypocaloric diet). Anthropometric parameters, fasting blood glucose, C-reactive protein (CRP), insulin concentration, insulin resistance (HOMA-IR), lipid profile and adipocytokines levels were measured. Genotype of MTNR1B gene polymorphism (rs10830963) was evaluated. Results: All anthropometric parameters, systolic blood pressure and leptin levels decreased in all subjects after both diets. This improvement of anthropometric parameters was higher in non G allele carriers than G allele carriers.

RESUMO

BACKGROUND: The role of ADIPOQ gene variants in weight loss after different dietary fat amounts remains unclear. OBJECTIVE: Our aim was to analyze the effects of ADIPOQ gene polymorphism rs266729 on metabolic changes after two different amounts of dietary fat in two hypocaloric diets. DESIGN: A population of 283 obese patients was recruited in a randomized clinical trial with two diets: Diet HF (high-fat diet: 38% carbohydrates, 24% proteins, and 38% fats) versus Diet LF (low-fat diet: 53% carbohydrates, 20% proteins, and 27% fats). Before and after 3 months, an anthropometric evaluation, an assessment of nutritional intake, and a biochemical analysis were carried out. The variant of the ADIPOQgene was assessed by real-time PCR. RESULTS: Weight loss was similar with both diets in both genotypes (CC vs. CG+GG). After dietary intervention with Diet HF, only subjects with CC genotype showed a significant improvement in insulin levels (-3.3 ± 0.6 vs. -1.8 ± 0.9 mU/L; p = 0.03) and the homeostasis model assessment for insulin resistance (HOMA-IR) (-1.3 ± 0.1 vs. -0.8 ± 0.2 units; p = 0.02). After Diet LF, subjects with CC genotype showed a significant improvement in total cholesterol levels (CC vs. CG+GG) (-15.3 ± 1.4 vs. -6.4 ± 1.3 mg/dL; p = 0.01), LDL cholesterol (-14.6 ± 1.8 vs. -6.4 ± 1.3 mg/dL; p = 0.01), insulin levels (-4.6 ± 1.0 vs. -1.6 ± 0.5 mU/L; p = 0.01), and HOMA-IR (-1.6 ± 0.1 vs. -1.0 ± 0.2 units; p = 0.02). Only subjects with CC genotype showed a significant increase of adiponectin levels after both diets (CC vs. CG+GG): Diet HF (10.6 ± 2.0 vs. 1.8 ± 1.0 ng/dL; p = 0.01) and Diet LF (16.1 ± 2.8 vs. 1.3 ± 1.0 ng/dL: p = 0.03). CONCLUSION: CC genotype of ADIPOQgene variantrs266729 was associated with a better metabolic response after both diets. Additionally, Diet LF produced a significant improvement in lipid profile in noncarriers of allele G.

RESUMO

BACKGROUND & AIMS: The risk allele (G) of rs10830963 in the melatonin receptor 1 B (MTNR1B) gene presents an association with obesity. We study the effect of this SNP on cardiovascular risk factors and weight loss secondary to 2hypocaloric diets. METHODS: 361 obese subjects were randomly allocated during 3 months (Diet M - high monounsaturated fat hypocaloric diet vs. Diet P - high polyunsaturated fat hypocaloric diet). Anthropometric parameters, fasting blood glucose, C-reactive protein (CRP), insulin concentration, insulin resistance (HOMA-IR), lipid profile and adipocytokines levels were measured. Genotype of MTNR1B gene polymorphism (rs10830963) was evaluated. RESULTS: All anthropometric parameters, systolic blood pressure and leptin levels decreased in all subjects after both diets. This improvement of anthropometric parameters was higher in non G allele carriers than G allele carriers. After dietary intervention with Diet M, (CC vs. CG + GG); total cholesterol (delta: -10.4 ± 2.1mg/dl vs. -6.4 ± 1.2mg/dl: P <.05), LDL-cholesterol (delta:-7.1 ± 0.9mg/dl vs. -2.8 ± 0.8mg/dl: P <.05), insulin (delta:-3.0 ± 0.8 UI/L vs. -2.0 ± 1.0 UI/L: P<.05) and HOMA-IR (delta:-3.4 ± 1.0 units vs. -2.9 ± 0.9 units: P<.05) improved in no G allele carriers. After Diet P, in the group of subjects without G allele CC, insulin levels (delta: -2.9 ± 1.0 UI/L vs. -0.6 ± 0.2 UI/L: P <.05) and HOMA-IR (delta (CC vs. CG + GG): -0.8 ± 0.2 units vs. -0.4 ± 0.3 units: P <.05) decreased, too. CONCLUSIONS: Our study detected a relationship of rs10830963 MTNR1B SNP with body weight loss and insulin resistance modification induced by 2different hypocaloric. Only monounsaturated enriched hypocaloric diet and in no-G allele carriers showed a significant effect on lipoproteins.

RESUMO

BACKGROUND & AIMS: A common G-to-A transition (rs670) in the APOA1 gene has been related with metabolism. We evaluate the association of this SNP with changes in lipid profile and insulin resistance in response to two diets. METHODS: 268 obese patients were randomly allocated to a high protein/low carbohydrate -Diet HP- vs. a standard hypocaloric diet -Diet S- for 9 months. Anthropometric and biochemical status were evaluated at 3 and 9 months. RESULTS: 179 subjects (66.8%) had the genotype GG, 79 patients GA (29.4%) and 10 subjects AA (3,8%). With both diets: the decrease of BMI, weight, waist circumference, fat mass was higher in A allele carriers than non-carriers. Also on both diets A allele carriers showed greater improvements in total cholesterol (-19.0 ± 2.5 mg/dl (non-A allele carriers -12.1 ± 2.0 mg/dl:p = 0.02 after Diet HP) and -13.1 ± 2.1 mg/dl (non-A allele carriers -8.9 ± 1.1 mg/dl:p = 0.02 after Diet S)), LDL-cholesterol (-18.0 ± 2.1 mg/dl (non-A allele carriers -8.3 ± 2.2 mg/dl:p = 0.01 after Diet HP) and -12.0 ± 1.5 mg/dl (non-A allele carriers -6.3 ± 2.3 mg/dl:p = 0.01 after Diet S)), insulin (-2.5 ± 0.2 mUI/L (in non A allele -1.8 ± 0.2 mUI/L:p = 0.01 after Diet HP) and -2.1 ± 0.1 mUI/L (non A allele carriers -1.2 ± 0.3 mUI/L:p = 0.01 after Diet S)), HOMA-IR (-1.3 ± 0.3 units (non A allele group -0.8 ± 0.2:p = 0.03 after Diet HP) and -1.1 ± 0.1 units (non A allele carriers -0.3 ± 0.2 mg/dl:p = 0.01 after Diet S)) than non-A allele carriers. CONCLUSIONS: A allele carriers of rs670 ApoA1 polymorphism showed a higher decrease of insulin resistance, LDL cholesterol and adiposity induced by two different hypocaloric diet than non A allele carriers.
