Obesity related risk for chronic kidney disease progression and cardiovascular disease after propensity score matching / Riesgo relacionado con la obesidad para la progresión de insuficiencia renal crónica y enfermedad cardiovascular tras emparejamiento por puntaje de propensión

Introduction: Obesity is a major health problem worldwide. It carries a markedly increased risk for multiple diseases such as type 2 diabetes mellitus, hypertension, cardiovascular disease (CVD) and chronic kidney disease (CKD). To complicate an already difficult topic a new subtype of obesity has been defined lately, the metabolically healthy obese. Our study aimed to clarify the association between obesity, metabolic syndrome and kidney disease progression. Methods: Observational retrospective single centre study including 212 patients with stage 3–4 CKD with no previous history of rapid kidney disease progression. Patients were divided according to BMI status and presence of metabolic syndrome. Anthropometric, clinical and laboratory data were collected to follow-up. Propensity score matching was performed for age, albuminuria and baseline renal function. During follow-up renal and cardiovascular events were recorded. Results: After a mean follow-up of 88.44±36.07 months a total of 18 patients reached the renal outcome in the non-obese group and 21 in the obese group. Differences were not statistically significant (log rank=0.21: p=0.64). Multiple Cox regression analysis showed that obesity was not predictor for worse renal outcomes [HR 1.01, 95% CI 0.45–2.24; p=0.97]. When stratifying the sample according to baseline metabolic syndrome and obesity presence there was no difference in renal survival (log rank=0.852; p=0.35) (AU)

Introducción: La obesidad es un problema mayor de salud a nivel mundial. Comporta un considerable incremento del riesgo de múltiples enfermedades tales como diabetes mellitus tipo 2, hipertensión, enfermedad cardiovascular (ECV) e insuficiencia renal crónica (IRC). Para complicar un tema ya difícil, se ha definido recientemente un nuevo subtipo de obesidad: el obeso metabólicamente sano. El objetivo de nuestro estudio fue aclarar la asociación entre obesidad, síndrome metabólico y progresión de la enfermedad renal. Métodos: Estudio observacional retrospectivo unicéntrico que incluyó a 212 pacientes con IRC estadio 3 a 4, sin antecedentes de progresión rápida de la enfermedad renal. Se dividió a los pacientes conforme a su situación de índice de masa corporal (IMC) y presencia de síndrome metabólico (SM). Durante el seguimiento se recopilaron los datos antropométricos, clínicos y de laboratorio. Se realizó el emparejamiento por puntaje de propensión (Propensity score matching) para edad, albuminuria y función renal nasal. Durante el seguimiento se registraron los episodios renales y cardiovasculares. Resultados: Tras un seguimiento medio de 88,44 ± 36,07 meses, un total de 18 pacientes logró el resultado renal en el grupo de no obesos, y 21 en el grupo de obesos. Las diferencias no fueron estadísticamente significativas (log rank=0,21: p = 0,64). El análisis de regresión múltiple de Cox mostró que la obesidad no era un factor predictivo para peores resultados renales [HR 1,01, IC95% 0,45–2,24; p 0,97]. Al estratificar la muestra con arreglo a síndrome metabólico basal y presencia de obesidad no existió diferencia en cuanto a la supervivencia renal (log rank = 0,852; p = 0,35). (AU)

Asociación entre resistencia a la insulina y proteína C reactiva en una muestra de peruanos no obesos / Association between insulin resistance and C-reactive protein in a sample of non-obese Peruvians

Introducción: El papel que juega la resistencia a la insulina (RI) en las enfermedades crónicas se debe en gran medida a la presencia de inflamación de bajo grado, a través de proteínas como la proteína C reactiva (PCR). Si bien hay datos que evidencian la relación entre la RI y la PCR, ello es escaso en población no obesa. Objetivo: Evaluar la asociación entre la RI y la PCR en una muestra de peruanos no obesos. Materiales y métodos: Estudio transversal analítico de base de datos secundario del estudio PERU MIGRANT. Resultados: Se encontró una prevalencia de RI de 3,72 %; mientras que la prevalencia de PCR alto (≥ 3 mg/L) en los sujetos de estudio fue 19,26 %. Los pacientes con PCR alto tenían 5,65 % mayor frecuencia de tener RI, en comparación con quienes tenían PCR normal (2,63% vs 8,28%; p= 0,003). Las mujeres tenían 1,49 % mayor frecuencia en tener RI, respecto a los varones (4,51 % vs 3,02 %; p= 0,336). Los pacientes con PCR alto tenían 214% mayor frecuencia de tener RI, en comparación a quienes no presentaban PCR alto (RP=3,14, IC95%: 1,52 ­ 6,50) y ajustando con las covariables confusoras (sexo, edad, IMC, grupo, estado de fumador, bebedor de alcohol y actividad física) el PCR alto tenían 198% mayor frecuencia de presentar RI, respecto a quienes no tenían PCR alto (RP=2,98; IC95%: 1,49 ­ 5,96). Conclusiones: En no obesos la presencia de PCR, en ausencia de patología infecciosa, podría suponer la existencia de RI.

Background:The role of insulin resistance (IR) in chronic disease is largely due to the presence of low-grade inflammation, through proteins such as C-reactive protein (CRP). Although there is evidence of a relationship between IR and CRP, this is scarce in non-obese population. To evaluate the association Objective:between IR and CRPin a sample of non-obese Peruvians.Material and methods:Cross-sectional analytical study of the secondary database of the PERU MIGRANTstudy. We found a prevalence of IR of 3.72 %; while the prevalence of high Results:CRP(≥ 3 mg/L) in the study subjects was 19.26 %. Patients with high CRPhad 5.65 % higher frequency of having RI, compared to those with normal CRP(2.63 % vs 8.28 %; p= 0.003). Females had 1.49 % higher frequency of having IR, compared to males (4.51 % vs. 3.02 %; p= 0.336). Patients with high CRPhad 214% higher frequency of having IR, compared to those without high CRP (PR=3.14, 95%CI: 1.52 - 6.50) and adjusting for confounding covariates (sex, age, BMI, group, smoking status, alcohol drinker and physical activity) high CRPhad 198% higher frequency of having IR, compared to those without high CRP(PR=2.98, 95%CI: 1.49 - 5.96). Conclusions:In non-obese patients, the presence of CRP, in the absence of infectious pathology, could imply the existence of IR.

Obesity related risk for chronic kidney disease progression and cardiovascular disease after propensity score matching.

INTRODUCTION: Obesity is a major health problem worldwide. It carries a markedly increased risk for multiple diseases such as type 2 diabetes mellitus, hypertension, cardiovascular disease (CVD) and chronic kidney disease (CKD).

Our study aimed to clarify the association between obesity, metabolic syndrome and kidney disease progression. METHODS: Observational retrospective single centre study including 212 patients with stage 3-4 CKD with no previous history of rapid kidney disease progression. Patients were divided according to BMI status and presence of metabolic syndrome. Anthropometric, clinical and laboratory data were collected to follow-up. Propensity score matching was performed for age, albuminuria and baseline renal function. During follow-up renal and cardiovascular events were recorded. RESULTS: After a mean follow-up of 88.44±36.07 months a total of 18 patients reached the renal outcome in the non-obese group and 21 in the obese group. Differences were not statistically significant (log rank=0.21: p=0.64). Multiple Cox regression analysis showed that obesity was not predictor for worse renal outcomes [HR 1.01, 95% CI 0.45-2.24; p=0.97]. When stratifying the sample according to baseline metabolic syndrome and obesity presence there was no difference in renal survival (log rank=0.852; p=0.35) A total of 48 cardiovascular events were registered: seventeen in the non-obese group and thirty-one in the obese group. Differences in event-free time between both groups were statistically significant (log rank=4.44;p=0.035), especially after four years of follow-up. After stratifying for MS and obesity presence at baseline the event-free time differences where again statistically significant (log rank=16.86;p=0.001), specially for the obese patients with metabolic syndrome. CONCLUSIONS: Obesity has little impact on chronic kidney disease progression despite the presence or absence of metabolic syndrome in a cohort matched for age, baseline renal function and albuminuria. Obesity conferred greater cardiovascular risk when combined with metabolic syndrome.

Impact of Grade I obesity on respiratory mechanics during video laparoscopic surgery: prospective longitudinal study / Impacto da obesidade Grau I na mecânica respiratória durante cirurgia videolaparoscópica: estudo longitudinal prospectivo

Abstract Introduction and objectives: The association pneumoperitoneum and obesity in video laparoscopy can contribute to pulmonary complications, but has not been well defined in specific groups of obese individuals. We assessed the effects of pneumoperitoneum in respiratory mechanics in Grade I obese compared to non-obese. Methods: Prospective study including 20 patients submitted to video laparoscopic cholecystectomy, normal spirometry, divided into non-obese (BMI ≤ 25 kg.m-2) and obese (BMI > 30 kg.mg-2), excluding Grade II and III obese. We measured pulmonary ventilation mechanics data before pneumoperitoneum (baseline), and five, fifteen and thirty minutes after peritoneal insufflation, and fifteen minutes after disinflation (final). Results: Mean BMI of non-obese was 22.72 ± 1.43 kg.m-2 and of the obese 31.78 ± 1.09 kg.m-2, p < 0.01. Duration of anesthesia and of peritoneal insufflation was similar between groups. Baseline pulmonary compliance (Crs) of the obese (38.3 ± 8.3 mL.cm H2O-1) was lower than of the non-obese (47.4 ± 5.7 mL.cm H2O-1), p = 0.01. After insufflation, Crs decreased in both groups and remained even lower in the obese at all moments assessed (GLM p < 0.01). Respiratory system peak pressure and plateau pressure were higher in the obese, albeit variations were similar at moments analyzed (GLM p > 0.05). The same occurred with elastic pressure, higher in the obese at all times (GLM p = 0.04), and resistive pressure showed differences in variations between groups during pneumoperitoneum (GLM p = 0,05). Conclusions: Grade I obese presented more changes in pulmonary mechanics than the non-obese during video laparoscopies and the fact requires mechanical ventilation-related care.

Resumo Justificativa e objetivos: Em videolaparoscopias, a associação de pneumoperitônio e obesidade pode contribuir para complicações pulmonares, mas não está bem definida em grupos específicos de obesos. Avaliamos os efeitos do pneumoperitônio na mecânica respiratória dos obesos Grau I em comparação aos não obesos. Métodos: Estudo prospectivo envolvendo 20 pacientes submetidos à colecistectomia videolaparoscópica, com espirometria normal, separados em não-obesos (IMC ≤ 25 kg.m-2) e obesos (IMC > 30 kg.mg-2), excluídos obesos Grau II e III. Mensuramos dados da mecânica ventilatória pulmonar antes do pneumoperitônio basal, após cinco, quinze e trinta minutos da insuflação peritoneal e quinze minutos após a desinsuflação final. Resultados: O IMC médio dos não obesos foi de 22,72 ± 1,43 kg.m-2 e dos obesos 31,78 ± 1,09 kg.m-2, p < 0,01. A duração da anestesia e da insuflação peritoneal foram semelhantes entre os grupos. A complacência pulmonar (Crs) basal dos obesos (38,3 ± 8,3 mL.cm H2O-1) foi inferior aos não obesos (47,4 ± 5,7 mL.cm H2O-1), p = 0,01. Após a insuflação, a Crs diminuiu nos dois grupos e permaneceu ainda mais baixa nos obesos em todos os momentos avaliados (GLM p < 0,01). A pressão de pico e a pressão de platô do sistema respiratório foram mais elevadas nos obesos, mas apresentaram semelhantes variações nos momentos analisados (GLM p > 0,05). O mesmo ocorreu com a pressão elástica, mais elevada nos obesos em todos tempos (GLM p = 0,04), e a pressão resistiva apresentou diferenças nas variações entre os grupos durante o pneumoperitônio (GLM p = 0,05). Conclusão: Obesos Grau I apresentam maiores alterações na mecânica pulmonar que os não obesos em videolaparoscopias e este fato recomenda cuidados relacionados a ventilação mecânica.

Evaluation of nonalcoholic fatty liver disease using magnetic resonance in obese children and adolescents / Avaliação de doença hepática gordurosa não alcoólica utilizando ressonância em crianças e adolescentes obesos

Abstract Objective: To determine the frequency of nonalcoholic fatty liver disease using nuclear magnetic resonance as a noninvasive method. Methodology: This was a cross-sectional study conducted on 50 children and adolescents followed up at an outpatient obesity clinic. The subjects were submitted to physical examination, laboratory tests (transaminases, liver function tests, lipid profile, glycemia, and basal insulin) and abdominal nuclear magnetic resonance (calculation of hepatic, visceral, and subcutaneous fat). Results: Nonalcoholic fatty liver disease was diagnosed in 14 (28%) participants, as a severe condition in eight (percent fat >18%), and as non-severe in four (percent fat from 9% to 18%). Fatty liver was associated with male gender, triglycerides, AST, ALT, AST/ALT ratio, and acanthosis nigricans. Homeostasis model assessment of insulin resistance and metabolic syndrome did not show an association with fatty liver. Conclusion: The frequency of nonalcoholic fatty liver disease in the present population of children and adolescents was lower than that reported in the international literature. It is suggested that nuclear magnetic resonance is an imaging exam that can be applied to children and adolescents, thus representing an effective noninvasive tool for the diagnosis of nonalcoholic fatty liver disease in this age range. However, further national multicenter studies with longitudinal design are needed for a better analysis of the correlation between nonalcoholic fatty liver disease and its risk factors, as well as its consequences.

Resumo Objetivo: Determinar a frequência da doença hepática gordurosa não alcoólica utilizando ressonância magnética nuclear como um método não invasivo. Metodologia: Este foi um estudo transversal realizado em 50 crianças e adolescentes acompanhadas em uma Clínica Ambulatorial de Obesidade. Os indivíduos foram submetidos a exame físico, testes de laboratório (transaminases, testes de função hepática, perfil lipídico, glicemia e insulina basal) e ressonância magnética nuclear abdominal (cálculo da gordura hepática, visceral e subcutânea). Resultados: A doença hepática gordurosa não alcoólica foi diagnosticada em 14 (28%) participantes, como uma condição grave em oito (percentual de gordura > 18%) e não grave em quatro (percentual de gordura de 9 a 18%). Fígado gorduroso foi associado a sexo masculino, triglicerídeos, aspartato aminotransferase (AST), alanina aminotransferase (ALT), proporção de AST/ALT e acanthosis nigricans. O Modelo de Avaliação da Homeostase de Resistência à Insulina e a síndrome metabólica não mostraram associação com fígado gorduroso. Conclusão: A frequência da doença hepática gordurosa não alcoólica na população atual de crianças e adolescentes foi inferior à relatada na literatura internacional. Sugerimos que a ressonância magnética nuclear seja um exame de imagem que pode ser aplicado em crianças e adolescentes, representando, assim, uma ferramenta não invasiva eficaz no diagnóstico de doença hepática gordurosa não alcoólica nessa faixa etária. Contudo, estudos multicêntricos nacionais adicionais de modelo longitudinal são necessários para uma melhor análise da correlação entre a doença hepática gordurosa não alcoólica e seus fatores de risco, bem como suas consequências.

[Body mass index and tri-ponderal mass index of 1,453 healthy non-obese, non-undernourished millennial children. The Barcelona longitudinal growth study]. / Índice de masa corporal e índice de masa triponderal de 1.453 niños no obesos ni malnutridos de la generación del milenio. Estudio longitudinal de Barcelona.

INTRODUCTION: Body mass index-for age (BMI) and tri-ponderal mass index-for-age (TMI) values of healthy non-underweight, non-obese millennial children have not been reported until now. We aimed to obtain these values. SUBJECTS AND METHODS: Longitudinal growth study (1995-2017) of 1,453 healthy non-underweight, non-obese millennial children, from birth (n = 477) or from 4 years of age (n = 976) to 18 years in girls and 19 years in boys (25,851 anthropometric measurements). RESULTS: In each sex, mean BMI-for-age values increased from birth to one year, declined until 5and increased from then onwards. Mean TMI-for-age values decreased abruptly during the first 6years of age and slowly thereafter, in both sexes. Although, at some ages, mean BMI-for age values differed statistically between sexes, differences were scant and of poor clinical significance. The same occurred for TMI-for-age values. BMI-for-age cut-off values to define underweight status (-2 SD) were similar to those proposed by Cole and the WHO for both sexes. However, BMI-for-age cut-off values to define obesity (+2 SD) were lower in both sexes (1.0-5.3) than those proposed by Cole and similar to those proposed by the WHO until 12 in girls and 14 in boys and lower (1.0-4.8) from these ages onwards. CONCLUSIONS: BMI-for-age and TMI-for-age values of healthy non-underweight, non-obese millennial children are provided. No clinically relevant differences were observed between sexes. These values may be used to measure underweight status and obesity in present pediatric populations and to evaluate the relationship between BMI-for-age and TMI-for-age in a clinical setting.

Effects of a psychological intervention on the quality of life of obese adolescents under a multidisciplinary treatment / Efeitos de uma intervenção psicológica sobre a qualidade de vida de adolescentes obesos em tratamento multidisciplinar

Abstract Objective: To investigate the effects of multidisciplinary treatment with and without psychological counseling on obese adolescents' self-reported quality of life. Methods: Seventy-six obese adolescents (15.87 ± 1.53 y) were allocated into psychological counseling group (PCG; n = 36) or control group (CG; n = 40) for 12 weeks. All participants received the same supervised exercise training, nutritional and clinical counseling. Participants in PCG also received psychological counseling. QOL was measured before and after 12 weeks of intervention by Generic Questionnaire for the Evaluation of Quality of Life (SF-36). Results: The dropout rate was higher in GC (22.5%) when compared with PCG (0.0%) (p < 0.001). After 12 weeks, participants from PCG presents lower body weight, relative fat mass and higher free fat mass (p < 0.001 for all) compared to GC. QOL improved among adolescents from both groups (p < 0.05), however, a better QOL was reported from those adolescents enrolled in PCG. Conclusion: The inclusion of a psychological counseling component in multidisciplinary treatment for adolescent obesity appears to provide benefits observed for improved QOL as compared with treatment without psychological counseling.

Resumo Objetivo: Investigar os efeitos do tratamento multidisciplinar com e sem aconselhamento psicológico voltado para a qualidade de vida de adolescentes obesos. Métodos: Foram alocados 76 adolescentes obesos (15,87 ± 1,53 ano) em um grupo de aconselhamento psicológico (GAP; n = 36) e um grupo de controle (GC; n = 40) por 12 semanas. Todos receberam o mesmo treinamento físico supervisionado e aconselhamento nutricional e clínico. Os participantes no GAP também receberam aconselhamento psicológico. A qualidade de vida foi avaliada antes e depois das 12 semanas de intervenção por meio do Questionário Genérico de Avaliação da Qualidade de Vida (SF-36). Resultados: O abandono do tratamento foi maior no GC (22,5%) em comparação com o GAP (0,0%) (p < 0,001). Após 12 semanas, os participantes do GAP apresentam menor peso corporal, massa gorda relativa e maior massa livre de gordura (p < 0,001 para todos) em comparação com o GC. A qualidade de vida melhorou entre os adolescentes de ambos os grupos (p < 0,05); contudo, uma melhor qualidade de vida foi relatada pelos adolescentes incluídos no GAP. Conclusão: A inclusão de aconselhamento psicológico no tratamento multidisciplinar dos adolescentes obesos parece proporcionar benefícios observados na melhoria da qualidade de vida, em comparação com o tratamento sem aconselhamento psicológico.

Efeitos da suplementação de fibras solúveis, dieta de cafeteria e exercício físico sobre aorta torácica de ratos / Effects of supplementation by soluble fibers, cafeteria diet and physical exercise on rats´ thoracic aorta

As fibras alimentares vêm despertando interesse de especialistas das áreas de nutrição e saúde. Elas contribuem para a redução do risco de desenvolvimento de doenças cardiovasculares, além de ajudar no processo de perda de peso, principalmente quando seu consumo é associado à atividade física. Entretanto existem poucos trabalhos associando o uso de fibras solúveis à uma dieta hipercalórica e ao exercício físico. Assim, objetivo desse estudo foi investigar os efeitos das fibras solúveis sobre a aorta torácica e perfil lipídico de ratos machos wistar sedentários e treinados submetidos à dieta de cafeteria. Os parâmetros morfométrico e estereológico: espessura íntima-média e densidade de volume do músculo liso e do colágeno e o perfil lipídico foram determinados. Não foram observadas alterações na espessura da parede vascular, densidade de volume do músculo liso e colágeno. No entanto, o perfil lipídico apresentou-se alterado com o uso da dieta de cafeteria. A fibra alimentar associada ao treinamento aeróbio e a uma dieta balanceada apresentou resultado eficaz, não alterando a morfologia do vaso.

Food fibers have recently been in the limelight of nutrition and health experts. They reduce the development of cardiovascular diseases and help in the process of loss weight especially when their intake is associated with physical activity. However, few studies are extant on the use of soluble fibers associated to a hypercalorie diet and physical exercise. Current analysis deals with the effects of soluble fibers on the thoracic aorta and lipid profile of sedentary and trained male Wistar rats subjected to a cafeteria diet. Morphometric and stereological parameters comprised mid thickness and density of the volume of the smooth muscle and collagen, and lipid profile. No changes were reported on the thickness of the vascular wall, density of volume of the smooth muscle and collagen. However, lipid profile was modified due to the cafeteria diet. Food fiber associated with aerobic training and with a balanced diet provided an efficacious result with no alteration in the vase´s morphology.

Análisis de la longitud de los telómeros en obesos metabólicamente sanos / Analysis of telomere length in the metabolically healthy obese

La obesidad es el principal componente del síndrome metabólico (SM) y determina la progresión de la enfermedad a las complicaciones metabólicas. Los individuos obesos metabólicamente sanos (OMS) parecen estar protegidos contra esas complicaciones. La longitud de los telómeros (LT) es un nuevo marcador del envejecimiento celular, que tiene una relación compleja con el SM. El objetivo principal de este estudio fue investigar por primera vez la LT en OMS y estudiar la asociación entre LT y el número de componentes del SM. Se estudió a 398 mujeres con una edad media de 46,76 ± 15,47 años (rango: 18-86 años), que se agruparon en: individuos con normopeso sin ningún componente del SM (NP0), obesos sin SM (OMS) y de acuerdo con el número de componentes de SM en los grupos sin ningún componentes de SM (0), con uno o 2 componentes (1 + 2) y con SM por la presencia de 3 o más componentes (SM). La LT de los OMS no se diferenció de la de los NP0, pero fue significativamente mayor que la de los individuos con SM (p = 0,032). Se observó una disminución de la LT con el aumento progresivo del número de componentes del SM (p = 0,004), en donde el grupo 0 presentó una LT significativamente mayor que los grupos 1 + 2 (p = 0,027) y SM (p = 0,003). Demostramos por primera vez que las mujeres OMS presentan una LT similar a las mujeres NP0 y más larga que aquellas mujeres con SM. Además, confirmamos que la LT se acorta con el aumento en el número de alteraciones del SM.

Obesity is the principal component in Metabolic Syndrome (MetS) and determines the progression of metabolic complications. Metabolically healthy obese individuals (MHO) seem to be protected against those complications. Telomere length (TL), as a novel marker of cellular aging, has a complex relationship with MetS. The principal aim of this study was to investigate TL in MHO, and to study the association between TL and the number of MetS components. A study was conducted on 398 women (mean age: 46.76 ± 15.47 years; range: 18 - 86 years), grouped according to the number of MetS components (0, 1 + 2, MetS), a group of normal-weight individuals with 0 MetS components (NW0), and a group of obese without MetS (MHO). No differences were found in the TL of the MHO group compared to the NW0, but it was significantly higher than that of individuals with MetS (P = .032). A decrease in TL was observed with a progressive increase in the number of MetS components (P = .004), whereas the group of individuals without MetS components had significantly longer TL than the groups with 1 and 2 components (P = .027), and MetS (P = .003). Shorter TL is not associated with MHO, but is related to MetS and with an increased number of metabolic abnormalities.

Pruebas de función hepática en escolares obesos / Tests of liver function in obese school children

La enfermedad de hígado graso no alcohólico (EHGNA) se manifiesta con daño hepático y se asocia a la obesidad. El objetivo fue detectar en escolares obesos el riesgo para desarrollar EHGNA, a través de un estudio observacional analítico, comparando el funcionalismo hepático con un grupo control y su relación con variables antropométricas, bioquímicas, dietéticas y actividad física. Se evaluaron en 160 escolares (7-11 años) la condición socioeconómica, el estado nutricional por el índice de masa corporal (IMC), área grasa (AG) del brazo (Proyecto Venezuela 1994), porcentaje de grasa corporal por antropometría (% GC), circunferencia de cintura (CC), tolerancia oral a la glucosa, insulinemia basal y postcarga de glucosa, CT, cLDL, cVLDL, cHDL, triglicéridos (TG), TGO, TGP, gammaglutamiltranspeptidasa (GGTP) y albúmina. La dieta se analizó por el recordatorio de 24 horas y la actividad física por una prueba clínica. En 88 escolares obesos se observaron mayores promedios (p<0,05) de TGP, mayor frecuencia (p<0,05) de TGO y TGP elevadas y de albúmina baja (p<0,05), que en los controles. La TGP se correlacionó significativamente con el IMC, AG, % GC, CC, insulina basal y postcarga de glucosa, HOMA, cVLDL, cHDL y TG, mientras que la TGO con el AG y la GGTP con AG, insulina basal, HOMA y cLDL. La albúmina se correlacionó negativamente con el IMC, AG, % GC y CC. La TGP fue la que más reflejó el compromiso hepático de la obesidad. Para evaluar el riesgo de EHGNA, se debe estandarizar los valores de TGO/TGP según edad, género y raza.

The non alcoholic fatty liver disease (NAFLD) manifests with liver damage and it is associated with obesity. The objective of this work was to detect the risk of obese school students of developing NAFLD, through an analytical, observational study, comparing their liver function with that of a control group, and its relationship with physical activity, dietary, biochemical and anthropometric variables. One hundred and sixty school students (ages 7-11) were evaluated according to their socio-economic status; nutritional status by the body mass index (BMI) and mid-upper arm fat area (MUAC) (Project Venezuela 1994); body fat percentage by anthropometry (% BF), waist circumference (WC); and metabolism by oral glucose tolerance, basal insulin and post-load glucose, total cholesterol (TC), cLDL, cVLDL, cHDL, triglycerides (TG), glutamic oxaloacetic transaminase (GOT), glutamic pyruvic transaminase (GPT), gamma glutamil transpeptidasa (GGTP) and albumin. Their diet was analyzed by the 24-hour recall and their physical activity by a clinical trial. Mean levels of GPT (p < 0.05), greater frequencies of elevated GOT and GPT (p < 0.05) and lower albumin levels (p < 0.05) were observed in 88 obese school students when compared to controls. The GPT correlated significantly with the BMI, MUAC, % BF, WC, basal insulin and post-load glucose, HOMA, cVLDL, cHDL and TG, while the GOT correlated with MUAC and the GGTP with MUAC, basal insulin, HOMA and cLDL. Albumin was negatively correlated with BMI, MUAC, % BF and WC. TGP reflected better the hepatic compromise of obesity. To assess the risk of NAFLD, the TGO/TGP values should be standardized according to age, gender and race.

Marcadores de estrés oxidativo y su relación con el estado nutricional en adultos, Ecuador / Relationships between biomarkers of oxidative stress and nutritional status in adults, Ecuador

Se evaluó la relación entre biomarcadores de estrés oxidativo (ácido úrico, bilirrubina y proteína C-reactiva) con el estado nutricional en 321 adultos de Ecuador, pertenecientes al personal administrativo de la Universidad Técnica del Norte, con edades de 43 ± 10 años, (46,30% femenino y 53,61% masculino). Se obtuvo información sociodemográfica, de estilo de vida y epidemiológica; se calculó el índice de Masa Corporal (IMC), porcentaje de grasa y agua corporal, se midió la circunferencia de la cintura (CC) y la presión arterial y se determinó las concentraciones de ácido úrico, bilirrubina y Proteína C reactiva (PCR). Se encontró que 17,9% de la población presentó obesidad y 51,72% sobrepeso. Los valores más elevados de ácido úrico se encontraron en obesos, hipertensos y en quienes realizan actividad física. La bilirrubina total, directa e indirecta se encontró en límites superiores en los grupos con obesidad abdominal, y con actividad física. Las variables % de grasa y de agua influyen en la PCR en el grupo con baja grasa corporal y en las mujeres. En hombres, la PCR se asocia con IMC y CC. En los grupos sobrepeso, alta grasa corporal y PHT, el ácido úrico mostró relación con el % de grasa y la CC En los obesos con el % de agua e IMC y en los grupos obesidad abdominal e HT se asoció con % de agua y CC Se concluye que el porcentaje de agua corporal es un importante indicador nutricional para el desarrollo de estrés oxidativo en esta población.

In this work it was evaluated the relationship between oxidative stress biomarkers (uric acid, bilirubin and C-reactive protein) with nutritional status in 321 adults of Ecuador, belonging to administrative staff of of the Universidad Tècnica del Norte , aged 43 ± 10 years old (46 30% female and 53.61% male). Socio demographic and epidemiological information and lifestyle were obtained through a survey; The Body Mass Index (BMI) and body fat and body water percentages were calculated; waist circumference (WC) and blood pressure was measured. Determinations of uric acid, bilirubin, and serum C-reactive protein (PCR) were performed. 17.9% of the populations were obese and 51.72% overweight. The highest values of uric acid were found in obese, hypertensive and physical activity groups. The total direct and indirect bilirubin were found in upper limits in abdominal obesity and physical activity groups. The CRP level was influenced by % fat and % water in the low body fat group and in females. In male, BMI and WC were associated with CRP. Uric acid showed relationship with % fat and WC in overweight, high body fat and PHT groups, uric acid was associated with the % water and BMI in obese. Finally, uric acid was associated with % water and the WC in the abdominal obesity, and HT groups’ .The body water percentage is an important indicator to development of oxidative stress in this population.

Marcadores de daño vascular y renal en orina en niños y adolescentes obesos / Vascular and renal damage markers observed in urine from obese children and adolescents

INTRODUCCIÓN: la microalbuminuria es considerada un marcador de disfunción endotelial, daño vascular, daño renal y enfermedad cardiovascular, considerada un factor de riesgo independiente de morbilidad y mortalidad. De igual manera, la proteinuria ha sido identificada como un factor de riesgo independiente de enfermedad renal crónica, y un predictor de todas las causas de mortalidad. Ambas, son relativamente frecuentes en los sujetos obesos. OBJETIVO: determinar la frecuencia de marcadores de daño vascular y renal en orina en niños y adolescentes obesos. MÉTODOS: se presenta un estudio observacional, analítico y prospectivo que incluyó a niños y adolescentes obesos atendidos en consulta de referencia "Obesidad y riñón", en el Hospital Pediátrico Docente de Centro Habana. El estudio fue realizado en el periodo comprendido entre enero de 2009 y diciembre de 2012. Se determinaron marcadores de daño vascular y renal en orina (microalbuminuria y proteinuria). El análisis estadístico fue realizado con el programa SPSS versión 13,0. RESULTADOS: solo a un paciente se le identificó proteinuria (0,5 %); sin embargo, al determinar la microalbuminuria, se encontró que más de la mitad (70,8 %) tenía este marcador de daño vascular y renal positivo. En el análisis histopatológico de la biopsia renal del paciente con proteinuria se encontró glomerulomegalia con lesión segmentaria de esclerosis y adherencia a la cápsula de Bowman. CONCLUSIONES: los niños y adolescentes obesos tienen una elevada frecuencia de positividad de marcadores de daño vascular y renal, fundamentalmente microalbuminuria.

INTRODUCTION: microalbuminuria is considered to be a marker of endothelial dysfunction, vascular damage, renal damage and cardiovascular disease in addition to be an independent risk factor for morbidity and mortality. Similarly, proteinuria has been identified as an independent risk factor for chronic renal disease and a predictor of all causes of mortality. Both are relatively frequent in obese subjects. OBJECTIVE: to determine the frequency of vascular and renal markers in the urine from obese children and adolescents. METHODS: prospective, observational and analytical study of obese children and adolescents seen at the reference service called obesity and kidney in the teaching pediatric hospital of Centro Habana. The study was conducted from January 2009 through December 2012. Vascular and renal markers were determined in the urine (microalbuminuria and proteinuria). The statistical analysis was based on SPSS program version 13.0. RESULTS: there was just one patient detected with proteinuria (0.5 %); however, in the microalbuminuria test, it was found that over half of the patients (70.8 %) were positive to this vascular and renal damage marker. In the histopathological analysis of the renal biopsy taken from the patient with proteinuria, segmental glomerulosclerosis and adhesion to Bowman's capsule was discovered. CONCLUSIONS: obese children and adolescents have very frequent positivity to vascular and renal damage markers, mainly microalbuminuria.

Objective: to identify prognostic variables associated with obesity in adolescents belonging to 5 neighboring polyclinics of San Antonio de los Baños, Artemisa province. Methods: a multicenter prospective cohort study was conducted in the period from January 2006 until May 2012 on 5 neighboring clinics and San Antonio de los Baños municipality, Artemisa province to determine prognostic variables associated with obesity as independent variable during adolescence. It was analyzed: clinical and demographic variables found, complementary laboratory exams utility, referred pathological family antecedents. It was calculated a sample for a relative risk of 23,1, 95 por ciento confidence and accuracy of 96 por ciento, randomly selected and matched by age and sex into 2 groups of 150 patients: group A obese and group B not obese.Results: central fat distribution RR 3,3 and prehypertension RR 3,1 were associated with obesity, with predominance of men 1,5 / 1 hypertriglyceridemia global mean 4,8 mmol/L DE ±2,8 and steatohepatitis 23,3 por ciento, positive complementary laboratory exams were more frequent in the obese, although the positive microproteinuria had wide sensitivity 0,83 and specificity 0,79. Obesity 23,3 por ciento and arterial hypertension 22,6 por ciento, personal antecedents had a higher incidence in group A. The morbidity analysis indicated central obesity coefficient 5,432 and microproteinuria as prognostic variables of greater interaction.Conclusions: prehypertension, visceral fat distribution and poor metabolic control constitute bad prognostic factors in obese adolescent whose vascular endothelium is early injured influenced by the genetic load (AU)

Association of insulin resistance and GLP-2 secretion in obesity: a pilot study / Associação entre resistência insulínica e secreção de GLP-2 em obesos: um estudo piloto

OBJECTIVE: The objective of this pilot study was to determine whether glugagon-like peptide 2 (GLP-2) secretion relates to insulin sensitivity (IS) in obese subjects. SUBJECTS AND METHODS: Twenty four obese subjects [body mass index (BMI) 40.0 ± 3.0 kg/m² (mean ± standard deviation)] were included, nine of which were male, age 43 ± 8 years. Twelve subjects had type 2 diabetes, all treated with oral anti-diabetic agents only. The subjects were submitted to standard meal tolerance test (MTT) for dosage of the curves: glucose, insulin, and GLP-2. Insulin sensitivity was measured by HOMA-IR, and OGIS was derived from the MTT. Spearman linear correlations and partial correlations were obtained. RESULTS: There was an inverse relationship between the GLP-2 secretion and IS: HOMA-IR correlated with GLP-2 AUC (R = 0.504; p = 0.012), and OGIS correlated with GLP-2 incremental AUC (R = -0.54; p = 0.054). The correlation persisted after controlling for BMI. CONCLUSION: We found an association of GLP-2 secretion and insulin resistance (IR). The understanding of the underlying mechanisms may provide future directions in the pharmacological manipulation of incretins, and in the treatment of obesity and related metabolic disorders.

OBJETIVO: O objetivo deste estudo piloto foi determinar a relação entre a secreção de glugagon like peptide 2 (GLP-2) e a sensibilidade insulínica (SI) em indivíduos obesos. SUJEITOS E MÉTODOS: Vinte e quatro indivíduos obesos [IMC 40.0 ± 3.0 kg/m² (média ± desvio-padrão)] foram incluídos no estudo, sendo 9 homens, com idade de 43 ± 8 anos. Do total, 12 indivíduos tinham diabetes tipo 2, todos tratados somente com antidiabéticos orais. Os sujeitos foram submetidos ao teste de refeição padrão (MTT) para dosagens das curvas: glicose, insulina e GLP-2. A sensibilidade insulínica foi mensurada pelos HOMA-IR e OGIS, obtidos pelos valores do MTT. As correlações lineares e correlações parciais foram obtidas. RESULTADOS: Observou-se uma relação inversa entre a secreção de GLP-2 e SI: HOMA-IR correlacionou-se com GLP-2 AUC (R = 0,504; p = 0,012) e OGIS correlacionou-se com GLP-2 incremental AUC (R = -0,54; p = 0,054). A correlação persistiu controlando o IMC. CONCLUSÃO: Encontramos uma associação entre a secreção de GLP-2 e a resistência insulínica. A compreensão desses mecanismos poderá direcionar o futuro farmacológico da manipulação de incretinas no tratamento da obesidade e das desordens metabólicas.
