ABSTRACT

El diagnóstico clínico de resistencia insulínica (RI) es difícil, ya que el Clamp no es aplicable a la clínica. El así llamado "síndrome metabólico", un predictor clínico de la RI, no identifica alrededor de la mitad de los sujetos afectados. Previamente, definimos adecuadamente (Análisis ROC) los niveles de corte diagnóstico de los siguientes predictores bioquímicos: HOMA1, HOMA2, QUICKI e ISI-Composite, a través de analizar datos de 90 sujetos (53 no resistentes y 37 resistentes) que tenían una medición directa de su resistencia insulínica (Test de supresión pancreática, TSP, Test de Reaven) y también, una curva de tolerancia a la glucosa oral (CTG). Los puntos de corte obtenidos exhibieron un mucho mejor desempeño diagnóstico comparados con los puntos de corte convencionales. También encontramos un predictor nuevo, simple, económico y eficiente, el I0*G60. Definimos la "normalidad metabólica" de la CTG usando las medianas de los valores de varios parámetros en 312 sujetos con un G120 dentro de los 2 primeros terciles del grupo de normo-tolerantes a la glucosa (NGT, n=468; G120: 51-110 mg/dL, los con mejor función beta insular). A las medianas de la función beta insular y de la sensibilidad insulínica se les asignó un valor de un 100%. Se calculó el % relativo de función beta insular (%RFBI) y el % relativo de sensibilidad insulínica (%RSI) del resto de la cohorte (n=573) contra estos valores de referencia. El "OGTT Squeezer" se escribió en Excel. Las glicemias y las insulinemias de la CTG fueron las entradas del programa. Las salidas fueron: I0*G60, ISI-OL, QUICKI, and HOMA1 (predictores) y el índice insulinogénico, el índice de disposición, %RFBI y %RSI (parámetros). El programa también caracterizó la tolerancia glucídica de acuerdo a los criterios de la ADA 2003. El formato final del programa, HTML 5, facilita su uso. Desarrollamos tres versiones del programa: completa, abreviada y mínima.


Clinically, diagnosing insulin resistance (IR) is difficult since the Clamp is not applicable to clinical work. The so-called "Metabolic Syndrome", a clinical surrogate of IR, fails to identify around 50% of affected subjects. Previously, we properly defined (ROC Analysis) the diagnostic cut-offs of the following biochemical predictors: HOMA1, HOMA2, QUICKI, and ISI-Composite by analyzing data from 90 subjects (53 non-insulin-resistant and 37 insulin-resistant subjects) who had a direct measurement of insulin resistance (Pancreatic Suppression Test, PST, Reaven's Test), and also, an Oral Glucose Tolerance Test (OGTT). The resulting cut-offs exhibited much better performances compared with the conventional cut-offs. We also found a new, simple, inexpensive and efficient predictor, the I0*G60. We chose to define the "metabolic normalcy" of the OGTT by using the median values of several parameters in 312 NGT subjects with a G120 in the first 2 tertiles of the NGT group (n=468; G120: 51-110 mg/dL, those with the best beta-cell function). The median values of both Beta-Cell Function and Insulin Sensitivity of these subjects were assigned a 100% value. Both % Relative Beta-Cell Function (%RBCF) and % Relative Insulin Sensitivity (%RIS) of everyone else in the cohort (n=573) was calculated against these reference values. The "OGTT Squeezer" was written in Excel. The OGTT's glucose and insulin values served as the inputs of the program. The outputs were: I0*G60, ISI-OL, QUICKI, and HOMA1 (predictors), and Insulinogenic Index, Disposition Index, %RBCF, and %RIS (parameters). Moreover, the program characterized the OGTT according to the ADA 2003 criteria. The HTML 5 format of the program facilitates its use. We developed 3 versions of the program: complete, abbreviated, and minimal versions.

ABSTRACT

To investigate the impact of family history of diabetes (FHD) on blood glucose, lipid levels and perinatal outcomes in pregnant women with gestational diabetes mellitus (GDM). A total of 1265 GDM women who gave childbirth in Women's Hospital, Zhejiang University School of Medicine during January to December 2019 were enrolled in the study, including 253 women with FHD and 1012 women without FHD. The -test or test were used to compare the blood lipid, blood glucose levels and perinatal outcomes including large for gestational age infant, small for gestational age infant, macrosomia, cesarean delivery, preeclampsia, preterm labor, postpartum hemorrhage, fetal distress. The correlation between FHD and perinatal outcomes were estimated by Logistic regression analysis. The high density lipoprotein level at third-trimester was significantly lower in GDM women with FHD (<0.05); and the women with FHD also had higher fasting blood glucose oral glucose tolerance test (OGTT)1 h, OGTT 2 h and glycosylated hemoglobin level (all <0.01). In GDM women, FHD was an independent risk factor for preeclampsia (=3.27, 95%: 1.39-7.68). GDM women with FHD have lower high density lipoprotein and higher glucose levels. FHD is an independent risk factor for preeclampsia in GDM women.

ABSTRACT

To explore the correlation of mid-term oral glucose tolerance test (OGTT) and maternal weight gain with adverse pregnancy outcomes in women with gestational diabetes mellitus (GDM). A total of 2611 pregnant women with GDM who were examined and delivered in Women's Hospital, Zhejiang University School of Medicine from July 1st 2017 to 30th June 2018 were enrolled in this study. According to the number of abnormal items of mid-term OGTT results or maternal gestational weight gain (GWG), patients were classified. The incidence of adverse perinatal outcomes in each group and its relation with OGTT results and GWG were analyzed. The incidence of gestational hypertension, premature delivery, macrosomia and large for gestational age infant (LGA) in three abnormal items GDM patients were significantly higher than those in one or two abnormal items GDM patients (all <0.017). The incidence of gestational hypertension and premature delivery in two abnormal items GDM patients were higher than those in one abnormal item GDM patients (all <0.017). The incidence of gestational hypertension and macrosomia in excessive GWG patients were significantly higher than those in inadequate and appropriate GWG patients (all <0.017), and the incidence of LGA were higher than that in inadequate GWG patients (all <0.017). The incidence of premature delivery and low birth weight infants in appropriate GWG patients were significantly lower than those in inadequate and excessive GWG patients, and the incidence of small for gestational age infant (SGA) were significantly lower than that in inadequate GWG patients (all <0.017). In one abnormal item GDM patients, inadequate GWG was a risk factor for premature delivery and SGA (=1.66, 95%: 1.10-2.52; =2.20, 95%: 1.07-4.53), and protective factor for LGA (=0.40, 95%: 0.27-0.59). And excessive GWG was a risk factor for gestational hypertension, premature delivery and low birth weight infants (=2.15, 95%: 1.35-3.41; =1.80, 95%: 1.20-2.72; =2.18, 95%: 1.10-4.30).In two abnormal items GDM patients, inadequate GWG was a protective factor for macrosomia and LGA (=0.24, 95%: 0.09-0.67; =0.54, 95%: 0.34-0.86), while excessive GWG was risk factor for premature delivery (=1.98, 95%: 1.23-3.18).In three abnormal items GDM patients, there was no significant relationship between GWG and adverse pregnancy outcomes. For GDM women with one or two items of elevated blood glucose in OGTT, reasonable weight management during pregnancy can reduce the occurrence of adverse pregnancy outcomes. For those with three items of elevated blood glucose in OGTT, more strict blood glucose monitoring and active intervention measures should be taken in addition to weight management during pregnancy.

ABSTRACT

To investigate the effect of dietary fiber on blood glucose and pregnancy outcomes in patients with gestational diabetes mellitus (GDM). One hundred and twelve patients with GDM in the second trimester of pregnancy were recruited from Women's Hospital, Zhejiang University School of Medicine. Patients were randomized into two groups with 56 in each group: the control group received basic nutrition support; while the dietary fiber group were given additional dietary fiber ( total dietary fiber per day) before meals in addition to basic nutrition support. Intervention for all cases lasted for 8 weeks. Fasting blood glucose and postprandial blood glucose (2 h BG) were measured every week, and oral glucose tolerance test (OGTT) was performed at 42 d postpartum to evaluate the glycemic outcomes. Perinatal outcomes were recorded. The dietary fiber intervention markedly improved 2 h BG in patients with GDM and significantly elevated the glucose compliance rate from the 3rd to 8th week compared to the control group ( <0.05 or <0.01). OGTT 2 h glucose and the incidence of impaired glucose tolerance in the dietary fiber group were significantly lower than those in the control group, while the glucose compliance rate was significantly higher than that in the control group (all <0.01). Moreover, the rates of adverse perinatal outcomes, such as premature rupture of membranes and neonatal hyperbilirubinemia were declined in the dietary fiber group (<0.05 or <0.01). Dietary fiber intervention can ameliorate hyperglycemia in GDM patients, improve perinatal outcomes and reduce the incidence of postpartum impaired glucose tolerance.

ABSTRACT

Objective@#The relationship between serum uric acid (SUA) levels and glycemic indices, including plasma glucose (FPG), 2-hour postload glucose (2h-PG), and glycated hemoglobin (HbA1c), remains inconclusive. We aimed to explore the associations between glycemic indices and SUA levels in the general Chinese population.@*Methods@#The current study was a cross-sectional analysis using the first follow-up survey data from The China Cardiometabolic Disease and Cancer Cohort Study. A total of 105,922 community-dwelling adults aged ≥ 40 years underwent the oral glucose tolerance test and uric acid assessment. The nonlinear relationships between glycemic indices and SUA levels were explored using generalized additive models.@*Results@#A total of 30,941 men and 62,361 women were eligible for the current analysis. Generalized additive models verified the inverted U-shaped association between glycemic indices and SUA levels, but with different inflection points in men and women. The thresholds for FPG, 2h-PG, and HbA1c for men and women were 6.5/8.0 mmol/L, 11.0/14.0 mmol/L, and 6.1/6.5, respectively (SUA levels increased with increasing glycemic indices before the inflection points and then eventually decreased with further increases in the glycemic indices).@*Conclusion@#An inverted U-shaped association was observed between major glycemic indices and uric acid levels in both sexes, while the inflection points were reached earlier in men than in women.

ABSTRACT

BACKGROUND@#The prevalence of skin diseases and diabetes mellitus (DM) are prominent around the world. The current scope of knowledge regarding the prevalence of skin diseases and comorbidities with type 2 DM (T2DM) is limited, leading to limited recognition of the correlations between skin diseases and T2DM.@*METHODS@#We collected 383 subjects from the Da Qing Diabetes Study during the period from July 9th to September 1st, 2016. The subjects were categorized into three groups: Normal glucose tolerance (NGT), impaired glucose tolerance (IGT), and T2DM. The prevalence and clinical characteristics of skin diseases were recorded and investigated.@*RESULTS@#In this cross-sectional study, 383 individuals with ages ranging from 53 to 89-year-old were recruited. The overall prevalence of skin diseases was 93.5%, and 75.7% of individuals had two or more kinds of skin diseases. Additionally, there were 47 kinds of comorbid skin diseases in patients with T2DM, of which eight kinds of skin diseases had a prevalence >10%. The prevalence of skin diseases in NGT, IGT, and T2DM groups were 93.3%, 91.5%, and 96.6%, respectively; stratified analysis by categories showed a statistically significant difference in "disturbances of pigmentation" and "neurological and psychogenic dermatoses". The duration of T2DM also significantly associated with the prevalence of "disturbances of pigmentation" and "neurological and psychogenic dermatoses". Subsequently, the prevalence of "disturbances of pigmentation" was higher in males than females in NGT (P < 0.01) and T2DM (P < 0.01) groups. In addition, the difference in the prevalence of "disturbances of pigmentation" was also significant in NGT and T2DM groups (P < 0.01).@*CONCLUSIONS@#There was a high prevalence of skin diseases in the Da Qing Diabetes Study. To address the skin diseases in the Da Qing Diabetes Study, increased awareness and intervention measures should be implemented.

ABSTRACT

Los avances en el campo de la fibrosis quística han aumentado la esperanza de vida de estos pacientes, por lo que cada vez es más prevalente la Diabetes Relacionada con la Fibrosis Quística (DRFQ) y sus complicaciones. La DRFQ se asocia a mayor morbimortalidad, deterioro de la función pulmonar y del estado nutricional. Por lo mismo, el manejo óptimo de esta patología depende de un diagnóstico precoz, tratamiento individualizado y vigilancia de las complicaciones diabéticas. El screening de DRFQ debe realizarse anualmente a partir de los 10 años, mediante una Prueba de Tolerancia a la Glucosa Oral (PTGO), lo cual permite el diagnóstico. El manejo de esta patología tiene por objetivo estabilizar y mejorar la función pulmonar y el estado nutricional y metabólico de los pacientes. Actualmente, la insulina es el tratamiento farmacológico de elección para controlar la hiperglicemia y el esquema de uso debe ser individualizado para cada persona. En caso de enfermedades agudas pueden existir mayores requerimientos de insulina. Además, se deben tener consideraciones especiales en cuanto a la dieta y la insuficiencia pancreática exocrina que presentan estos pacientes. Para la vigilancia de complicaciones microvasculares se debe realizar una monitorización anual a partir de los 5 años desde el diagnóstico de DRFQ. Debido a la complejidad de estos pacientes, para alcanzar el mejor cuidado posible se necesita un enfoque multidisciplinario con distintos profesionales de la salud coordinados, incluyendo en la toma de decisiones al paciente y su familia.


Advances made in the field of cystic fibrosis have increased the life expectancy of these patients, which is why Cystic Fibrosis-Related Diabetes (CFRD) and its complications are becoming more and more prevalent. CFRD is associated with increased morbidity and mortality, lower lung function and inadequate weight maintenance. Therefore, the optimal management of this pathology depends on an early diagnosis, individualized treatment and monitoring of diabetic complications. For CFRD, routine screening with an Oral Glucose Tolerance Test (OGTT) should be carried out yearly from the age of 10, which allows to diagnose it. The treatment goals in CFRD are to stabilize and improve lung function and obtain adequate weight gain. Currently, insulin is the pharmacological treatment of choice to control hyperglycemia and the insulin regimen must be personalized for each person. In acute illnesses, there may be higher insulin requirements. In addition, special considerations must be taken regarding diet and exocrine pancreatic insufficiency that these patients present. For the surveillance of microvascular complications, annual monitoring should be carried out 5 years after the diagnosis of CFRD. Due to the complexity of these patients, in order to achieve the best possible care, a multidisciplinary approach is needed with different coordinated health professionals, including the patients and their family in the decision-making process.

ABSTRACT

ABSTRACT OBJECTIVE: Determine the value of the combination of fasting glucose less than the 10th percentile (FG < p10) during 75 gram oral glucose tolerance test (75g OGTT) with maternal characteristics to predict low birth weight (LBW) established by Intergrowth-21st tables. METHODS: Prospective cohort study of pregnant women who was underwent 75g OGTT between 24 and 28.6 weeks. The 10th percentile fasting glucose of the population was determined at 65 mg/dL and women with risk factors that could modify fetal weight, including those related to intrauterine growth restriction, were excluded. Two groups were formed: group FG < p10 and group with normal fasting glucose. The main finding was the diagnosis of LBW. The association between FG < p10, maternal characteristics and LBW was established by multivariate logistic regression. The predictive performance of the models constructed was evaluated by receiver operating characteristic (ROC) curve and area under the curve (AUC) analysis. RESULTS: 349 women were eligible for study, of whom 66 (18.91%) had FG < p10; neonates in this group had lower birth weights (2947.28 g and 3138.26 g, p = 0.001), higher frequencies of LBW (25% and 6.81%, p < 0.001) and of weights < 2500 g in term births (8.6% and 2.3%, p = 0.034). The basal prediction model consisted of nulliparity by achieving an AUC of 60%, while the addition of FG < p10 resulted in the significant improvement of the previous model (AUC 72%, DeLong: p = 0.005). CONCLUSIONS: In pregnant women without factors that could modify fetal weight, the predictive model created by combining FG < p10 during 75g OGTT with nulliparity was significantly associated with increased risk of LBW. REGISTRATION: ClinicalTrials.gov: NCT04144595.


RESUMEN OBJETIVO: Determinar el valor de la combinación de la glucosa en ayunas menor que el percentil 10 (GA < p10) durante la prueba de tolerancia oral a la glucosa con 75 gramos (PTG-75g) con características maternas para predecir bajo peso al nacer (BPN) establecido mediante tablas de Intergrowth-21st. MÉTODOS: Estudio de cohorte prospectivo de mujeres embarazadas que se realizaron PTG-75g entre las 24 y 28.6 semanas. Se determinó el percentil 10 de glucosa en ayunas de la población en 65 mg/dL y fueron excluidas aquellas mujeres con factores de riesgo que pudieran modificar el peso fetal incluyendo los relacionados con la restricción del crecimiento intrauterino. Se formaron dos grupos: grupo GA < p10 y grupo con glucosa en ayunas normal. El hallazgo principal fue el diagnóstico de BPN. La asociación entre GA < p10, características maternas y BPN se estableció mediante regresión logística multivariante. El desempeño predictivo de los modelos construidos fue evaluado por el análisis de la curva característica operativa del receptor (ROC) y del área bajo la curva (ABC). RESULTADOS: Fueron elegibles para estudio 349 mujeres, de las cuales 66 (18,91%) tuvieron GA < p10; los neonatos de este grupo tuvieron pesos al nacer más bajos (2947.28 g y 3138.26 g, p = 0,001), frecuencias más altas de BPN (25% y 6,81%, p < 0,001) y de pesos < 2500 g en nacimientos de término (8,6% y 2,3%, p = 0,034). El modelo basal de predicción consistió en nuliparidad al lograr un ABC del 60%, mientras que al añadir la GA < p10 se obtuvo la mejora significativa del modelo previo (ABC 72%, DeLong: p = 0,005). CONCLUSIONES: En mujeres embarazadas sin factores que pudieran modificar el peso fetal, el modelo predictivo creado combinando GA < p10 durante la PTG-75g con nuliparidad estuvo asociado significativamente con riesgo incrementado de BPN. REGISTRO: ClinicalTrials.gov: NCT04144595.

ABSTRACT

Background An instrument to help clinicians to evaluate the oral glucose tolerance test (OGTT) at-a-glance is lacking. Aim To generate a program written in HTML squeezing relevant information from the OGTT with glucose and insulin measurements. Material and Methods We reanalyzed a database comprising 90 subjects. All of them had both an OGTT and a pancreatic suppression test (PST) measuring insulin resistance directly. Thirty-seven of the 90 studied participants were insulin resistant (IR). Receiver operating characteristic (ROC) curves and Bayesian analyses delineated the diagnostic performances of four predictors of insulin resistance: HOMA, QUICKI, ISI-OL (Matsuda-DeFronzo) and I0*G60. We validated a new biochemical predictor, the Percentual Relative Insulin Sensitivity (%RIS), and calculated the Percentual Relative Beta Cell Function (%RBCF). Results The best diagnostic performance of the five predictors were those of the I0*G60 and the %RIS. The poorest diagnostic performances were those of the HOMA and QUICKI. The ISI-OL's performance was in between. The %RIS of participants with and without IR was 44.4 ± 7.3 and 101.1 ± 8.8, respectively (p < 0.05). The figures for % RBCF were 55.8 ± 11.8 and 90.8 ± 11.6, respectively (p < 0.05). Mathematical modeling of the relationship between these predictors and the Steady State Plasma Glucose Value from the PST was performed. We developed a program with 10 inputs (glucose and insulin values) and several outputs: I0*G60, HOMA, QUICKI, ISI-OL, Insulinogenic Index, Disposition Index, %RBCF, %RIS, and metabolic categorization of the OGTT (ADA 2003). Conclusions The OGTT data permitted us to write successfully an HTML program allowing the user to fully evaluate at-a-glance its metabolic information.

ABSTRACT

ABSTRACT Objective The insulin tolerance test (ITT) has been accepted as the gold standard test for assessing the integrity of the growth hormone (GH) - insulin-like growth factor (IGF-1) axis and the hypothalamic-pituitary-adrenal (HPA) axis. The goal of the test is to achieve clinical and biochemical hypoglycemia at a blood glucose level ≤ 40 mg/dL to effectively and correctly assess the HPA and GH-IGF-1 axes. In this study, the GH and cortisol responses of patients who achieved and failed to achieve biochemical hypoglycemia during an ITT were compared. Subjects and methods One hundred thirty-five patients with pituitary disorders were included in the study. Samples for blood glucose levels were obtained after clear symptoms of clinical hypoglycemia developed. The patients were enrolled in the hypoglycemic and nonhypoglycemic groups according to whether their plasma glucose level ≤ 40 mg/dL or > 40 mg/dL during an ITT, and the groups were compared in terms of their GH and cortisol responses. Results The mean age, body mass index and waist circumference of the two patient groups were found to be similar. The mean blood glucose level was significantly lower in the hypoglycemic group than in the nonhypoglycemic group (19.3 and 52.0 mg/dL, respectively). When the two groups were compared in terms of peak cortisol and GH responses, no statistically significant differences were found. Conclusion The data presented suggest that clinically symptomatic hypoglycemia is as effective as biochemically confirmed hypoglycemia during an ITT. Arch Endocrinol Metab. 2020;64(1):82-8

ABSTRACT

SUMMARY OBJECTIVE To evaluate two different criteria, one or two cut-off values, of oral glucose tolerance test with 75g of glucose for the diagnosis of gestational diabetes mellitus. METHODS A cross-sectional study involving 120 records of pregnant women who received prenatal care at the service of a Brazilian university was carried out. Bivariate analysis of obstetric and perinatal outcomes was performed using the chi-square test. RESULTS Considering criterion I, 12.5% of patients were diagnosed with gestational diabetes mellitus. Patients were 3.57 times more likely to have a large fetus for the gestational age at birth (p=0.038). Using criterion II, gestational diabetes mellitus was diagnosed in 5.8% of patients, macrosomia was 7.73 times more likely to be found in the presence of gestational diabetes mellitus (p=0.004), and a large fetus for the gestational age at birth was 8.17 times more likely (p=0.004). CONCLUSIONS There was a difference in the prevalence of gestational diabetes mellitus between the two criteria analyzed. The new criterion proposed increased prevalence.


RESUMO OBJETIVO Avaliar dois critérios distintos, um ou dois valores de corte, do teste oral de tolerância à glicose com 75 g de glicose para o diagnóstico de diabetes mellitus gestacional. Métodos Estudo transversal envolvendo 120 prontuários de gestantes que realizaram pré-natal em um ambulatório de uma universidade brasileira. Análise bivariada dos resultados obstétricos e perinatais foi realizada pelo teste do qui-quadrado. Resultados Considerando o critério I, 12,5% das pacientes foram diagnosticadas com diabetes mellitus gestacional. As pacientes apresentaram uma chance 3,57 maior de ter um feto grande para a idade gestacional (p=0,038). Utilizando o critério II, o diabetes mellitus gestacional foi diagnosticado em 5,8% das pacientes. Mediante esse critério diagnóstico, a chance de macrossomia foi 7,73 vezes mais provável na presença de diabetes mellitus gestacional (p=0,004) e a chance de um feto grande para a idade gestacional foi 8,17 vezes maior de ocorrer (p=0,004). Conclusões Observou-se diferença na prevalência de diabetes melittus gestacional entre os dois critérios analisados, sendo que o novo critério proposto aumentou a prevalência.

ABSTRACT

RESUMEN El objetivo de este trabajo fue evaluar el efecto de las diferentes concentraciones de polidextrosa en la prevención de la obesidad y sus comorbilidades, en ratas alimentados con dieta hipercalórica. Se utilizaron ratas machos Wistar, repartidos en 4 grupos: Grupo control (HC) y 3 grupos que recibieron dieta hipercalórica con suplementación del 2%, 4% y 6% de polidextrosa (HC2%P, HC4%P y HC6%P respectivamente). La dieta hipercalórica utilizada fue la del tipo de cafetería para inducir la obesidad. Se midió peso corporal e ingesta de la dieta, se realizaron pruebas de tolerancia a la glucosa y a la insulina. Los animales fueron sometidos a eutanasia para toma de muestra de sangre medidas antropométricas y pesaje de órganos y tejidos. La polidextrosa disminuyó significantemente el peso, la grasa corporal, la glicemia, los triglicéridos, la intolerancia a la glucosa y la resistencia a la insulina, y aumentó los niveles del colesterol HDL. Se concluye que el consumo de poli- dextrosa redujo las complicaciones derivadas de la obesidad en ratas alimentados con dieta hipercalórica, siendo éste un potencial tratamiento para el control de la obesidad, la diabetes tipo II y las enfermedades cardiovasculares.


ABSTRACT The aim of this study was to evaluate the effect of different polydextrose concentrations for the prevention of obesity and its comorbidities in rats fed a high calorie diet. Thirty male Wistar rats were used. Rats were divided into 4 groups: Control group (HC) and 3 groups which received a hypercaloric diet with 2%, 4% and 6% polydextrose supplementation (HC2%P, HC4%P and HC6%P, respectively). The hypercaloric diet used was of the cafeteria type to induce obesity. Body weight and feed intake were verified weekly. Glucose and insulin tolerance tests were performed five days before finalizing the experiment. At the end of the experiment, animals were euthanized for blood collection, anthropometric measurements and tissue weighing. Polydextrose significantly decreased weight, body fat, blood glucose, triglycerides, glucose intolerance and insulin resistance and increased HDL cholesterol levels. The use of polydextrose reduced the complications of obesity in mice fed a hypercaloric diet. In conclusion, polydextrose may be a promising treatment for controlling obesity, diabetes type II and cardiovascular diseases.

Abstract Objective To assess the prevalence of gestational diabetes mellitus and the main associated risk factors in the population served by the Brazilian Unified Health System in the city of Caxias do Sul, state of Rio Grande do Sul. Materials and Methods A descriptive, cross-sectional and retrospective study was conducted. Maternal variables were collected from the medical records of all pregnant women treated at the basic health units in 2016. Hyperglycemia during pregnancy (pregestational diabetes, overt diabetes and gestational diabetes mellitus) was identified by analyzing the results of a 75-g oral glucose tolerance test, as recommended by the Brazilian Ministry of Health. Based on the data, the women were allocated into two groups: the gestational diabetes group and the no gestational diabetes group. Results The estimated prevalence of gestational diabetes among 2,313 pregnant women was of 5.4% (95% confidence interval [95%CI]: 4.56-6.45). Pregnant women with 3 or more pregnancies had twice the odds of having gestational diabetes compared with primiparous women (odds ratio [OR]=2.19; 95%CI: 1.42-3.37; p<0.001). Pregnant women aged 35 years or older had three times the odds of having gestational diabetes when compared with younger women (OR=3.01; 95%CI: 1.97-4.61; p<0.001). Overweight pregnant women were 84% more likely to develop gestational diabetes than those with a body mass index lower than 25 kg/m2 (OR =1.84; 95%CI: 1.25-2.71; p=0.002). A multivariable regression analysis showed that being overweight and being 35 years old or older were independent variables. Conclusion In this population, the prevalence of gestational diabetes mellitus was of 5.4%. Age and being overweight were predictive factors for gestational diabetes.


Resumo Objetivo Avaliar a prevalência de diabetes mellitus gestacional, e dos principais fatores de risco associados, em população usuária do Sistema Único de Saúde em Caxias do Sul-RS. Métodos Um estudo descritivo, transversal e retrospectivo foi feito. As variáveis maternas foramcoletadas de registros de prontuários de todas gestantes atendidas nas Unidades Básicas de Saúde do município em 2016. A identificação de hiperglicemia na gestação (diabetes pré-gestacional, diabetes identificado durante a gestação e diabetes mellitus gestacional) foi feita pela avaliação dos resultados do teste oral de tolerância com 75 g glicose, conforme preconizado pelo Ministério da Saúde. Com base nesses dados, as gestantes foram separadas em dois grupos: o grupo com diabetes gestacional e o grupo sem diabetes gestacional. Resultados A prevalência estimada de diabetes gestacional em 2.313 gestantes foi de 5,4% (intervalo de confiança de 95% [IC95%]: 4,56-6,45). Gestantes com 3 ou mais gestações apresentaram chance 2 vezes maior para a ocorrência de diabetes gestacional, quando comparadas às primigestas (razão de possibilidades [RP]=2,19; IC95%: 1,42- 3,37; p<0,001). Gestantes com idade de 35 anos ou mais apresentaram chance três vezes maior do que as mais jovens (RP=3,01; IC95%: 1,97-4,61; p<0,001). A chance de desenvolver diabetes gestacional em gestantes com sobrepeso foi 84% maior do que a das comíndice demassa corporal inferior a 25 kg/m2 (RP=1,84; IC95%: 1,25-2,71; p=0,002). A análise de regressão multivariada mostrou sobrepeso e idade materna como variáveis com associação independente. Conclusão Nesta população, a prevalência de diabetes mellitus gestacional foi de 5,4%. Idade materna e sobrepeso pré-gestacional foram fatores preditivos para diabetes gestacional.

ABSTRACT

BACKGROUND: To evaluate the association between serum 25-hydroxyvitamin D (25(OH)D) at mid-pregnancy and postpartum glucose intolerance in women with gestational diabetes mellitus (GDM).METHODS: We enrolled 348 pregnant women diagnosed with GDM from August 2012 to October 2016. We measured serum 25(OH)D levels at mid-pregnancy and carried out a 75-g oral glucose tolerance test at 6 to 12 weeks after delivery. Vitamin D deficiency was defined as serum 25(OH)D <20 ng/mL.RESULTS: The prevalence of vitamin D deficiency was 76.7% (n=267). Women with vitamin D deficiency had a higher prevalence of postpartum glucose intolerance than did those without vitamin D deficiency (48.7% vs. 32.1%, P=0.011). Serum 25(OH)D level was negatively correlated with hemoglobin A1c at antepartum and postpartum period (antepartum: r=−0.186, P=0.001; postpartum: r=−0.129, P=0.047). Homeostasis model assessment of β-cell function was positively correlated with serum 25(OH)D level only postpartum (r=0.138, P=0.035). The risk of postpartum glucose intolerance was 2.00 times (95% confidence interval, 1.13 to 3.55) higher in women with vitamin D deficiency than in those without vitamin D deficiency (P=0.018).CONCLUSION: In women with GDM, vitamin D deficiency at mid-pregnancy is associated with an elevated risk of postpartum glucose intolerance.

ABSTRACT

ABSTRACT Objective To investigate the effects of sericin extracted from silkworm Bombyx mori cocoon on morphophysiological parameters in mice with obesity induced by high-fat diet. Methods Male C57Bl6 mice aged 9 weeks were allocated to one of two groups - Control and Obese, and fed a standard or high-fat diet for 10 weeks, respectively. Mice were then further subdivided into four groups with seven mice each, as follows: Control, Control-Sericin, Obese, and Obese-Sericin. The standard or high fat diet was given for 4 more weeks; sericin (1,000mg/kg body weight) was given orally to mice in the Control-Sericin and Obese-Sericin Groups during this period. Weight gain, food intake, fecal weight, fecal lipid content, gut motility and glucose tolerance were monitored. At the end of experimental period, plasma was collected for biochemical analysis. Samples of white adipose tissue, liver and jejunum were collected and processed for light microscopy analysis; liver fragments were used for lipid content determination. Results Obese mice experienced significantly greater weight gain and fat accumulation and had higher total cholesterol and glucose levels compared to controls. Retroperitoneal and periepididymal adipocyte hypertrophy, development of hepatic steatosis, increased cholesterol and triglyceride levels and morphometric changes in the jejunal wall were observed. Conclusion Physiological changes induced by obesity were not fully reverted by sericin; however, sericin treatment restored jejunal morphometry and increased lipid excretion in feces in obese mice, suggesting potential anti-obesity effects.


RESUMO Objetivo Investigar os efeitos da sericina extraída de casulos de Bombyx mori na morfofisiologia de camundongos com obesidade induzida por dieta hiperlipídica. Métodos Camundongos machos C57Bl6, com 9 semanas de idade, foram distribuídos em Grupos Controle e Obeso, que receberam ração padrão para roedores ou dieta hiperlipídica por 10 semanas, respectivamente. Posteriormente, os animais foram redistribuídos em quatro grupos, com sete animais cada: Controle, Controle-Sericina, Obeso e Obeso-Sericina. Os animais permaneceram recebendo ração padrão ou hiperlipídica por 4 semanas, período no qual a sericina foi administrada oralmente na dose de 1.000mg/kg de massa corporal aos Grupos Controle-Sericina e Obeso-Sericina. Parâmetros fisiológicos, como ganho de peso, consumo alimentar, peso das fezes em análise de lipídios fecais, motilidade intestinal e tolerância à glicose foram monitorados. Ao término do experimento, o plasma foi coletado para dosagens bioquímicas e fragmentos de tecido adiposo branco; fígado e jejuno foram processados para análises histológicas, e amostras hepáticas foram usadas para determinação lipídica. Resultados Camundongos obesos apresentaram ganho de peso e acúmulo de gordura significativamente maior que os controles, aumento do colesterol total e glicemia. Houve hipertrofia dos adipócitos retroperitoneais e periepididimais, instalação de esteatose e aumento do colesterol e triglicerídeos hepáticos, bem como alteração morfométrica da parede jejunal. Conclusão O tratamento com sericina não reverteu todas as alterações fisiológicas promovidas pela obesidade, mas restaurou a morfometria jejunal e aumentou a quantidade de lipídios eliminados nas fezes dos camundongos obesos, apresentando-se como potencial tratamento para a obesidade.

ABSTRACT

RESUMEN Introducción: En Cuba no existe consenso acerca del valor del índice de conicidad que debe ser considerado de riesgo para identificar disglucemias. Objetivos: Determinar el punto de corte del índice de conicidad como predictor de disglucemia en ambos sexos. Métodos: Estudio descriptivo transversal con 975 personas (523 mujeres y 452 hombres), que asistieron a consulta externa del Instituto Nacional de Endocrinología por sospecha de diabetes mellitus entre abril de 2008 y abril de 2013. Se les realizó interrogatorio, examen físico y estudios complementarios (prueba de tolerancia oral a la glucosa, insulinemia en ayunas, lípidos y ácido úrico). Se utilizó para el procesamiento estadístico el coeficiente de correlación de Pearson, análisis de regresión logística y el análisis de curvas Receiver Operator Characteristic. Resultados: En el sexo femenino se observó una correlación directamente proporcional y significativa entre el índice de conicidad y las variables glucemia en ayunas y a las 2 h, insulinemia en ayunas, colesterol, triglicéridos, ácido úrico y el índice "homeostasis model assessment of insulin resistance". En el sexo masculino se observó una correlacióndirectamente proporcional y significativa entre el índice de conicidad y las variables estudiadas, excepto con los triglicéridos. El índice de conicidad tuvo su mayor poder predictor de disglucemia con un punto de corte de 1,18 para las mujeres y 1,20 en hombres. Conclusiones: El punto de corte óptimo del índice de conicidad como predictor de disglucemia fue de 1,18 para las mujeres y 1,20 para los hombres; es decir que tuvo un buen poder predictivo de disglucemias en el sexo femenino, no así en el masculino(AU)


ABSTRACT Introduction: In Cuba, there is no consensus about the value of the conicity index that should be considered as risk to identify dysglycemia. Objective: To determine the cut-off point of conicity index as a predictor of dysglycemia in both sexes. Methods: Cross-sectional descriptive study was conducted with 975 people (523 women and 452 men), who attended an outpatient consultation at the National Endocrinology Institute for suspected diabetes mellitus from April 2008 to April 2013. Interrogation, physical examination and complementary studies (oral glucose tolerance test, fasting insulinemia, lipids and uric acid) were performed. Pearson's correlation coefficient, logistic regression analysis and Receiver Operator Characteristic curve analysis were used for statistical processing. Results: In the female subjects, a directly proportional and significant correlation was observed between the conicity index and the fasting blood glucose variables and at 2 h, fasting insulinemia, cholesterol, triglycerides, uric acid and the index homeostasis model assessment of insulin resistance. In the male subjects, a directly proportional and significant correlation was observed between the conicity index and the variables studied, except with triglycerides. The conicity index had its highest predictive power of dysglycemia with a cut-off point of 1.18 in women and 1.20 in men. Conclusions: The optimal cut-off point of conicity index as a predictor of dysglycemia was 1.18 for women and 1.20 for men; that is to say, it was a good predictor of dysglycemias in the female subjects, but not so for male subjects(AU)

ABSTRACT

RESUMEN Introducción: La resistencia a la insulina es frecuente en el síndrome de ovario poliquístico, con diferencias entre fenotipos y discrepancias sobre cómo medirla. Objetivo: Identificar trastornos de la sensibilidad y resistencia a la insulina en mujeres con síndrome de ovario poliquístico, y determinar si es mayor en el fenotipo clásico. Métodos: Incluyó 152 mujeres: 45 sin síndrome de ovario poliquístico (Grupo I); 46 con síndrome de ovario poliquístico clínico (Grupo II); 61 con síndrome de ovario poliquístico clásico (Grupo III). Se realizó prueba de tolerancia a la glucosa oral, se calcularon índices de sensibilidad o resistencia a la insulina en ayunas (HOMA-IR, I0/G0, FIRI, ISI, Belfiore, Bennet, Quicki, Raynaud) y en la prueba de tolerancia a la glucosa oral (Belfiore2, Ribel, Ins2glu2, ATI, IITotal, DATI/DATG, Matsuda, BetaHOMA). Se emplearon las pruebas de Kruskal-Wallis, Mann-Whitney y Chi cuadrado. Resultados: Las mujeres con síndrome de ovario poliquístico tenían más obesidad global y central (p / 0,05), más nivel de glucemia a los 30, 120 y 180 minutos de la prueba de tolerancia a la glucosa oral (p / 0,05) y de insulinemia a los 30, 60 y 120 (p / 0,0001), lo que fue mayor en el grupo III. Se diagnosticó intolerancia en ayunas en una mujer de cada grupo y tolerancia alterada en una del II y III. No hubo diferencias significativas entre grupos para los índices de sensibilidad o resistencia a la insulina en ayunas; ni del HOMA entre mujeres normopeso vs. sobrepeso-obesidad (p / 0,05). La mediana de los índices de la prueba de tolerancia a la glucosa oral fue menor para los de sensibilidad (Belfiore2, Ribel) y mayor para los de resistencia a la insulina (Ins2glu2, ATI, IITotal) en el Grupo III. El DATI/DATG, Matsuda y BetaHOMA no tuvieron diferencias significativas. Conclusiones: Las mujeres con síndrome de ovario poliquístico tienen mayor respuesta glucémica, resistencia a la insulina e hiperinsulinismo postsobrecarga de glucosa que las mujeres con función ovárica normal, más manifiesta en el fenotipo clásico. Los índices de ayuno son menos sensibles, independientemente del peso corporal. Tienen mayor utilidad: insulinemia a los 60 minutos de la prueba de tolerancia a la glucosa oral, Belfiore2, ATI e IITotal(AU)


ABSTRACT Introduction: Insulin resistance is common in polycystic ovary syndrome, with differences between phenotypes and discrepancies on how to measure it. Objective: To identify disorders of insulin sensitivity and resistance in women with polycystic ovarian syndrome and determine if the latter is greater in the classic phenotype. Methods: The study included 152 women. 45 of them had no polycystic ovary syndrome (Group I), 46 had clinical polycystic ovary syndrome (Group II) and 61 had classic polycystic ovary syndrome (Group III). Oral glucose tolerance test was performed, fasting insulin sensitivity or resistance indices (HOMA-IR, I0 / G0, FIRI, ISI, Belfiore, Bennet, Quicki, Raynaud) were calculated and the tolerance test to oral glucose (Belfiore2, Ribel, Ins2glu2, ATI, IITotal, DATI / DATG, Matsuda, BetaHOMA) was also assessed. Kruskal-Wallis, Mann-Whitney and Chi square tests were used. Results: Women with polycystic ovarian syndrome had more global and central obesity (p /0.05), more blood glucose level at 30, 120 and 180 minutes of the oral glucose tolerance test (p /0.05 ) and insulinemia at 30, 60 and 120 (p /0.0001), which was higher in group III. Fasting intolerance was diagnosed in one woman in each group and altered tolerance in one of group II and group III, respectively. There were no significant differences between groups for fasting insulin sensitivity or resistance indices, nor for HOMA among normal weight women vs. overweight-obesity (p / 0.05). The median indexes of the oral glucose tolerance test were lower for those of sensitivity (Belfiore2, Ribel) and higher for those of insulin resistance (Ins2glu2, ATI, IITotal) in Group III. The DATI / DATG, Matsuda and BetaHOMA had no significant differences. Conclusions: Women with polycystic ovarian syndrome have higher glycemic response, insulin resistance and post-overload glucose hyperinsulinism than women with normal ovarian function, which is more evident in the classical phenotype. Fasting rates are less sensitive, regardless of body weight. Tests such as insulinemia 60 minutes after the oral glucose tolerance, Belfiore 2, ATI and IITotal are most useful(AU)

ABSTRACT

La acromegalia, originada por un exceso de producción de Hormona de crecimiento (Gh), se caracteriza por crecimiento somático exagerado, alto riesgo cardio-metabólico, así como reducción de la expectativa de vida. Tiene una incidencia de 3-4 casos por millón de habitantes. El diagnóstico se retrasa hasta 10 años aumentando la morbi-mortalidad. Las alternativas terapéuticas incluyen medicamentos y cirugía, que van encaminados a reducir los efectos de masa tumoral, normalizar los parámetros bioquímicos y resolver las manifestaciones clínicas. En casos muy infrecuentes, el tumor hipofisario que la origina se asocia a silla turca vacía.


Acromegaly, caused by an excess production of growth hormone (Gh), it is characterized by exaggerated somatic growth, high cardio-metabolic risk, as well as reduction of life expectancy. It has an incidence of 3-4 cases per million population. The diagnosis is delayed up to 10 years increasing morbidity and mortality. The therapeutic alternatives include medications and surgery, which are aimed at reduce the effects of tumor mass, normalize biochemical parameters and resolve clinical manifestations. In very infrequent cases, the pituitary tumor that originates it is associated with empty sella syndrome. Key words: Acromegaly, Empty sella syndrome, Pituitary tumor.

ABSTRACT

ABSTRACT Objective: To investigate the relationship of flavonoid intake during pregnancy with maternal excessive body weight and gestational diabetes mellitus (GDM). Subjects and methods: A cross-sectional study was conducted among 785 adult women in singleton pregnancies, and data were collected at the time of the oral glucose tolerance test. For the body mass index (BMI) classification according to the gestational age, the criteria of Atalah was used, and the diagnosis of GDM was based on the World Health Organization of 2014. Two 24-hour dietary recalls were obtained, and the usual intake was determined by the Multiple Source Method. Adjusted multinomial logistic regression was used to investigate the relationship of the flavonoids with overweight and obesity, and adjusted non-conditional logistic regression for the relationship of the flavonoids with GDM. Results: The mean (SD) age of the women was 28 (5) years, 32.1% were overweight, 24.6% were obese and 17.7% were diagnosed with GDM. The median (P25, P75) of total flavonoid intake was 50 (31,75) mg/day. Considering the eutrophic women as the reference, the pregnant women with a higher total flavonoid intake [OR 0.62 (95% CI 0.38; 0.96)] and anthocyanidin intake [OR 0.62 (95% CI 0.40; 0.99)] were less likely to be obese when compared to the women with lower intakes. No association of the flavonoids intake with overweight or GDM was found. Conclusion: A very low intake of flavonoids was observed. The data suggest that the intake of foods naturally rich in total flavonoids and anthocyanidin has a beneficial role regarding obesity among pregnant women.
