Implication of gestational diabetes treatment on maternal weight gain and low neonatal weight: a large retrospective cohort study / Implicación del tratamiento de la diabetes gestacional en el aumento de peso materno y bajo peso neonatal: gran estudio de cohorte retrospectivo

Objective: the treatment for gestational diabetes is based on diet, and this may modify maternal weight gain. The limited maternal weight gain is related to newborns with small weight for their gestational age (SGA), and many studies have found an increase of SGA in women with gestational diabetes (GD), but the reason for this is not clear. The objective of this study is to evaluate the effects of gestational diabetes treatment on maternal weight gain and neonatal weight. Methods: a retrospective cohort study of 1,765 patients with GD, according to the National Diabetes Data Group (NDDG) criteria. We assessed: pre-pregnancy BMI, total maternal weight gain (MWG), weight gain during the third trimester, gestational week of starting the treatment, and treatment modality (diet or diet plus insulin). Birth weight was adjusted by gestational age and gender: SGA (= 10th) and large for gestational age (LGA) ( > 90th). Results: the percentage of newborns with weight percentile = 10 was 14.8%. The diet and the time of initiation of the treatment were related to maternal weight gain (MWG) in the third trimester. For every 1 kcal/kg of variation in the diet (increase or decrease), a MWG variation of 0.03 (0.001-0.06) kg occurred (p < 0.01). For each week before the beginning of treatment, the mother did not gain 0.13 ± [(-0.15) - (-0.11)] kg in the third trimester (p < 0.01). The SGA was related to the lowest MWG in total gestation: 7.0 (IQR 3.0-10.4) kg vs. 8.4 (IQR 5.0-11.6) kg (p < 0.01), and in the third trimester: 0.3 (IQR -0.9-1.5) kg vs. 0.9 (IQR -0.3-2.2) kg (p < 0.01). Conclusion: the dietary treatment for gestational diabetes leads to a lower maternal weight gain and induces an impact on neonatal weight

Objetivo: el tratamiento para la diabetes gestacional se basa en la dieta y esto puede modificar el aumento de peso materno. Un aumento de peso materno limitado está relacionado con recién nacidos con bajo peso para su edad gestacional (SGA). Muchos estudios han encontrado un aumento de niños con bajo peso en mujeres con diabetes gestacional, pero la razón de esto no está clara. El objetivo de este estudio es evaluar los efectos del tratamiento de la diabetes gestacional sobre el aumento de peso materno y el peso neonatal. Métodos: estudio de cohortes retrospectivo en 1765 pacientes con diabetes gestacional, según los criterios de los National Diabetes Data Groups (NDDG). Evaluamos: IMC antes del embarazo, aumento de peso materno total (MWG), aumento de peso durante el tercer trimestre, semana gestacional de inicio del tratamiento y modalidad de tratamiento (dieta o dieta más insulina). El peso al nacer se ajustó por edad gestacional y género: SGA (percentil de = 10) y grande para la edad gestacional (LGA) (percentil de > 90). Resultados: el porcentaje de recién nacidos con peso percentil de = 10 fue del 14,8%. La dieta y el momento de inicio del tratamiento se relacionaron con el aumento de peso materno en el tercer trimestre. Por cada 1 kcal/kg de variación en la dieta (aumento o disminución) se produjo una variación de aumento del peso materno de 0,03 (0,001-0.06) kg (p < 0,01). Por cada semana antes de inicio del tratamiento, la madre dejó de ganar 0,13 ± [(- 0,15) - (- 0,11)] kg en el tercer trimestre (p < 0,01). El SGA se relacionó con un aumento de peso materno más bajo en el total de la gestación: 7,0 (IQR 3,0-10,4) kg vs. 8,4 (IQR 5,0-11,6) kg (p < 0,01), y en el tercer trimestre: 0,3 (IQR -0,9-1,5) kg vs. 0,9 (IQR -0,3-2,2) kg (p < 0,01). Conclusión: el tratamiento dietético para la diabetes gestacional puede conducir a un menor aumento de peso materno y a su vez inducir un impacto en el peso neonatal

Hyperuricemia and metabolic syndrome in children with overweight and obesity

Objetivo: Estudiar la prevalencia de hiperuricemia en niños con sobrepeso u obesidad y analizarla relación con el síndrome metabólico y las enfermedades que lo definen. Materiales y métodos: Se realizó un estudio de prevalencia transversal en 148 niños con sobrepeso u obesidad (12 ± 3 años, 48% chicos, IMC 31,8 ± 6,1) reclutados de una consulta de endocrinología pediátrica. Se determinaron el IMC, la cintura-talla, el perímetro de la cintura, la presión arterial con el equipo habitual y la glucosa (en ayunas y tras sobrecarga con 75 g), la resistencia a la insulina, el colesterol HDL, los triglicéridos y el ácido úrico. Resultados: La prevalencia de hiperuricemia era del 53%. Los pacientes con hiperuricemia tenían valores superiores de IMC (33,9 frente a 30,6; p = 0,003), perímetro de cintura (101,4frente a 91,1 cm; p < 0,001) y presión arterial sistólica (123,4 frente a 111,9 mmHg; p < 0,001)y diastólica (78,2 frente a 68,7 mmHg; p < 0,001). Mostraban además una glucemia más alta después de la sobrecarga oral de glucosa (107,5 frente a 100,7 mg/dl; p = 0,03), valores superiores de insulina (29,2 frente a 20,7 mg/dl; p = 0,001) y HOMA IR (6,5 frente a 4,4; p < 0,001) y concentraciones más bajas de HDL (49,5 frente a 54,4 mg/dl; p = 0,02).El valor de ácido úrico correspondiente con mayor probabilidad al diagnóstico de síndrome metabólico en nuestra muestra era de 5,4 mg/dl (sensibilidad del 64% y especificidad del 62%).Conclusión: La prevalencia de hiperuricemia en niños con sobrepeso y obesidad es alta. En el grupo de pacientes con obesidad e hiperuricemia hallamos que los parámetros determinados para diagnosticar el síndrome metabólico eran menos favorables. La concentración de ácido úrico a partir de la cual existe una mayor posibilidad de encontrar síndrome metabólico es de5,4 mg/dl (AU)

Objective: To study the prevalence of hyperuricemia in children with overweight or obesity and analyze the relation with metabolic syndrome and the diseases that define it. Materials and methods This is a cross-sectional prevalence study in 148 children recruited from pediatric endocrinology consultation, with overweight or obesity (12±3 years, 48% boys, BMI 31.8±6.1). We measured BMI, waist-height, waist circumference, blood pressure with standard instrumentation and glucose (fasting and after overload with 75g), insulin resistance, cholesterol HDL, triglycerides and uric acid. Results The prevalence of hyperuricemia was 53%. Patients with hyperuricemia had greater BMI (33.9 vs 30.6, p=0.003), plus waist circumference (101.4 vs 91.1cm, p<0.001), higher blood pressure: systolic (123.4 vs 111.9mm Hg, p<0.001), diastolic (78.2 vs 68.7mm Hg, p<0.001). They presented greater blood glucose after overload oral glucose (107.5 vs 100.7mg/dl, p=0.03), insulin was higher (29.2 vs 20.7mg/dl, p=0.001) as well as HOMA IR (6.5 vs 4.4, p<0.001) and HDL levels were lower (49.5 vs 54.4mg/dl, p=0.02).Uric acid's level which most is the likely diagnosis of metabolic syndrome corresponds to 5.4mg/dl in our sample (sensitivity: 64% and specificity 62%).Conclusion The prevalence of hyperuricemia in children with overweight and obesity is high. In the group of patients with obesity and hyperuricemia, we found out that the parameters measured to diagnose with metabolic syndrome were less favorable. Uric acid's level from where there is a higher possibility to see metabolic syndrome is 5.4mg/dl (AU)

[Prevalence of carbohydrate metabolism disturbances in a population of children and adolescents with severe obesity]. / Prevalencia de alteraciones del metabolismo hidrocarbonado en una población infanto-juvenil con obesidad grave.

INTRODUCTION: There is currently a disproportionate increase in childhood and adolescent obesity worldwide, together with other disorders involving substantial cardiometabolic risk in adulthood, such as alterations in carbohydrate metabolism. OBJECTIVE: To establish the prevalence of prediabetes, defined as impaired fasting glucose (IFG) and/or impaired glucose tolerance (IGT) after an oral glucose tolerance test, and the prevalence of type 2 diabetes mellitus (DM-2) in a pediatric population with severe obesity. Additionally, we aimed to assess clinical metabolic differences between prediabetic obese patients and obese subjects without prediabetes. MATERIAL AND METHODS: A cross-sectional study was carried out in children and adolescents with severe obesity (>97th percentile). The variables studied were age, sex, height, weight, body mass index, waist circumference, fasting plasma glucose and oral glucose tolerance test, insulinemia, insulin resistance assessed by the homeostasis model assessment (HOMA) index, glycated hemoglobin (HbA(1c)), triglycerides, high-density lipoprotein cholesterol (HDL), and systolic and diastolic blood pressure. RESULTS: A total of 133 patients were included: 67 boys (50.4%) and 66 girls (49.6%), with a mean age of 12.17±3.27 years. Fourteen patients (10.52%) had prediabetes (10 IFG, 3 IGT, 1 IFG+IGT): 7 girls and 8 boys, with a mean age of 13.2±3.3 years. One patient had DM2 (0.75%). Patients with prediabetes had significantly higher concentrations of fasting glucose (98±10.76 vs 88.53±6.3mg/d; p=0.001), insulinemia (35.38±14.22 vs 22.95±14.30µU/ml; p=0.009) and HOMA index (8.10±3.24 vs 4.89±3.27; p=0.004) than patients without impaired carbohydrate metabolism. These patients also had higher values of HbA(1c), triglycerides, blood pressure and HDL concentrations, although differences were not statistically significant. CONCLUSIONS: The prevalence of prediabetes (IFG/IGT) in children with severe obesity was high (10.52%). These patients should therefore be investigated to establish early diagnosis and appropriate treatment. Obese patients with prediabetes have significantly higher levels of insulin and insulin resistance than individuals without impaired carbohydrate metabolism.

Revisión casuística en el hospital universitario de Getafe de pacientes con patología hipofisaria adenomatosa intervenidos quirúrgicamente / Casuistry review of patients undergoing surgery for pituitary adenomas in Getafe University Hospital (Spain)

Objetivo Revisión casuística de pacientes diagnosticados de adenomas hipofisarios (AH) que han sido intervenidos en nuestro centro desde el año 1995 por el mismo neurocirujano. Material y métodos Estudio retrospectivo descriptivo de 98 pacientes intervenidos por AH entre 1995–2008. Se analizó tamaño tumoral, datos de funcionalidad, anatomía patológica y complicaciones posquirúrgicas. La distribución de los datos se hizo atendiendo a la fecha de cirugía en 2 grupos: 1995–2002 (1.er periodo) y 2003–2008 (2.° periodo).Resultados Se realizaron 110 intervenciones quirúrgicas. En el 1.er periodo tuvieron lugar 59 intervenciones y en el 2.° se realizaron 51. De estas, 49 fueron AH no funcionantes y 61 funcionantes. Se hallaron 85 macroadenomas y 25 microadenomas. Resultados Del total de macroadenomas, la curación se obtuvo en 31 pacientes (36%) frente a 21 (84%) en de los microadenomas. P<0,05. El número de complicaciones fue significativamente mayor en el 1.er periodo; 32 pacientes (54%) frente a 16 pacientes en el 2.° periodo (31,3%). P<0,05. En el 1.er periodo se curaron 28 pacientes (47,4%) y en el segundo 31 (52,1%). P=0,1. Tasa de mortalidad: 0,9%.ConclusionesLa tasa de curación de microadenomas es significativamente superior a la de macroadenomas como ya se describe en trabajos previos. Se evidencia de manera significativa una menor incidencia de complicaciones quirúrgicas y una tendencia al aumento del porcentaje de curación global en el 2.° periodo del estudio. Estos resultados probablemente estén en relación con el aumento de la experiencia del neurocirujano debido a la adquisición de destreza quirúrgica (AU)

Objective To perform a casuistry review of patients diagnosed with pituitary adenomas (PA) who underwent surgery performed by the same neurosurgeon after 1995.Material and methods A descriptive and retrospective study was performed in 98 patients with PA undergoing surgery from 1995–2008. Tumor size and data on functionality, pathology and postprocedural complications were analyzed. The study was divided into two periods: 1995–2002 (first period) and 2003–2008 (second period).Results A total of 110 surgical interventions (59 in the first period and 51 in the second) were performed for 49 non-hormone-producing PA and 61 hormone-producing PA. There were 85 macroadenomas and 25 microadenomas. Cure was achieved in 31 patients (36%) with macroadenomas and in 21 patients (84%) with microadenomas (P=0.05).The number of complications was significantly higher in the first period [32 patients (54 %)] than in the second period [16 patients (31.3%)] (P<0.05). Cure was achieved in 28 patients (47.4%) in the first period compared with 31 (52.1%) in the second (P=0.1). The mortality rate was 0.9%.ConclusionsAs described in previous studies, the cure rate was significantly higher for microadenomas than for macroadenomas. There was a significant reduction in the incidence of surgical complications and a trend toward an increase in the percentage of overall healing in the second period of the study. These results are probably related to the neurosurgeon's greater experience and surgical skill (AU)

Importancia de la lactancia materna en la prevalencia de síndrome metabólico y en el grado de obesidad infantil / Importance of breastfeeding in the prevalence of metabolic syndrome and degree of childhood obesity

Objetivos: El objetivo de nuestro estudio es evaluar la relación entre lactancia materna (LM) y prevalencia de obesidad y síndrome metabólico, en un grupo de niños y adolescentes obesos. Material y métodos: Se realizó un estudio retrospectivo en niños y adolescentes con obesidad tratados en el Servicio de Endocrinología y Nutrición del Hospital de Getafe (Madrid). Las variables estudiadas fueron edad, sexo, talla, peso, índice de masa corporal (IMC), circunferencia de cintura (CC), índice cintura-talla (ICT), presión arterial (PA), triglicéridos, lipoproteínas de alta densidad y glucemia basal. Asimismo, se recogió información sobre la alimentación recibida en los primeros meses de vida, considerando LM positiva la recibida durante al menos 3 meses. El programa estadístico utilizado fue SPSS v.15. Resultados: Se reclutó a 126 pacientes obesos (71 niños y 55 niñas), con una media de edad de 11,94 ± 3,12 años; 117 (92,86%) de ellos presentaron obesidad mórbida (IMC > P97 para edad y sexo). Todos los pacientes presentaban CC > P90 para edad y sexo. De los 126 pacientes evaluados, el 36,8% recibió LM durante más de 3 meses, y el 63,2%, sólo lactancia artificial (LA). Frente a los pacientes alimentados con LA, aquellos que recibieron LM presentaban menor IMC (31,53 ± 5,77 frente a 32,08 ± 6,78) y menor CC (95,02 ± 3,4 frente a 95,69 ± 3,2 cm), aunque no se alcanzó la significación estadística. La prevalencia de síndrome metabólico en la población estudiada fue del 19,8%. Dentro de este grupo, el 64% no había recibido LM frente a un 36% alimentado con LA. Conclusiones: Haber recibido LM durante al menos 3 meses conllevó un menor grado de obesidad, menor CC y menos complicaciones relacionadas con el síndrome metabólico durante la infancia y la adolescencia. El 64% de los niños con síndrome metabólico completo habían sido alimentados con LA. Son necesarios más estudios para conocer el impacto de la LM en el desarrollo de obesidad y riesgo cardiometabólico (AU)

Objectives: To evaluate the relationship between breastfeeding and the prevalence of obesity and metabolic syndrome in a group of obese children and adolescents. Material and methods: We performed a retrospective study in obese children and adolescents treated at the Endocrinology and Nutrition Service of the Hospital de Getafe (Madrid). The variables studied were age, sex, height, weight, body mass index (BMI), waist circumference, waist-height ratio, blood pressure, triglycerides, high-density lipoprotein and fasting glucose. Information was also collected on food received in the first months of life. Breastfeeding was defined as feeding with maternal milk for at least 3 months. The SPSS v.15 statistical package was used. Results: A total of 126 patients with obesity were recruited (71 boys and 55 girls) with a mean age of 11.94 ± 3.12 years. Of these, 117 (92.86%) were morbidly obese (BMI > 97th percentile for age and sex). All patients had a waist circumference > 90th percentile for age and sex. Of the 126 patients evaluated, 36.8% were breastfed for more than 3 months and 63.2% were fed with artificial milk only. Compared with patients fed with artificial milk, those who were breast fed had a lower BMI (31.53 ± 5.77 vs 32.08 ± 6.78) and lower waist circumference (95.02 ± 3.4 vs. 95.69 ± 3.2 cm), although this difference was not statistically significant. The prevalence of metabolic syndrome in the study population was 19.8%. Within this group, 64% had not been breast fed compared with 36% who had been fed with artificial milk. (..) (AU)
