Exploring Nutritype Signature of Type 2 Diabetes Risks in Women Post-Gestational Diabetes Mellitus...

Type 2 DiabetesGestational Diabetes

Women post-gestational diabetes mellitus (GDM) have more than 7-fold increased risk of having future type 2 diabetes mellitus (T2DM). While a healthful dietary pattern reduces the risk of diabetes in post-GDM, no data support a dietary pattern tailored to the Malaysian diet. To address this issue, the investigators propose to determine the effects of dietary patterns and plasma metabolites in predicting the risk of T2DM known as the Nutritype model. The aim of this study is to identify Nutritype signatures of T2DM risk in women post-GDM using metabolomics approach.

Micronutrients in Pregnancy as a Risk Factor for Diabetes and Effects on Mother and Baby

Gestational Diabetes

There is a rapidly escalating epidemic of obesity and type 2 diabetes across the world, with the fastest rise occurring in low- and middle-income countries. India not only has one of the highest rates in the world, but the disease starts at a younger age and lower levels of body weight than in UK white caucasians. Among city-dwelling Indians, approximately 8% of people aged 30-40 years already have diabetes. This is creating a heavy burden of disease and disability, and an intolerable economic burden through medical costs and lost earnings. Until now, efforts to prevent diabetes have mainly focussed on modifying the diet, lifestyle and activity of at-risk adults (for example those who are overweight, have a family history of diabetes or already have high blood sugar). However, recent research has indicated that factors acting in early life (during development in the womb) place an individual at risk of later diabetes. These include maternal malnutrition and low birthweight, and diabetes in the mother during pregnancy. Our research has shown that Indian mothers often have low vitamin B12 levels, which in turn causes high blood levels of a harmful metabolite (homocysteine). We have shown that these mothers get more diabetes in pregnancy. Their children are more likely to born with a low birth weight, and develop more body fat and higher plasma insulin levels during childhood, which are signs of higher diabetes risk in later life. The risk is increased further if the mother has normal or high status for another B vitamin, folate. Thus, we have shown, for the first time a link between a specific nutritional deficiency in the mother and diabetes risk in the next generation. One possible mechanism for the effect of maternal nutrition on risk of diabetes in her children is through epigenetic effects, whereby the nutritional environment during early development affects the switches that control gene expression. Since these switches are passed on via either parent, we think it is possible that paternal vitamin B12 status could also be important.

Diagnostic Approaches in Gestational Diabetes and Impact of Ethnicity

DiabetesGestational

Gestational diabetes (GDM) means raised blood glucose found for the first time in pregnancy. GDM is common, particularly in women from minority ethnicities. GDM does not cause any symptoms in the mother. GDM is associated with adverse pregnancy outcomes which can be improved with treatment of GDM. The United Kingdom National Institute for Health and Care Excellence (NICE) recommend pregnant women with one or more risk factors should have a 75g oral glucose tolerance test (OGTT). The OGTT is performed in a clinic with venous plasma glucose measured fasting and at 2 hours. This is resource-intensive, and some women with GDM may be missed by this risk-factor based approach. The International Association of Diabetes and Pregnancy Study Groups (IADPSG 2010) recommends screening all pregnant women with 2-hour, 3 sample (fasting, 1 and 2 hour), 75g OGTT, which is even more resource intensive. Developing more cost-effective and convenient approaches to screening for GDM is a priority. The researchers will validate a new home-use OGTT system (hOGTT), which measures whole blood glucose in capillary blood ('finger-stick' sample), against the gold standard venous plasma glucose in pregnancy. The researchers will also investigate the performance of glycated haemoglobin (HbA1c) in screening for GDM. HbA1c is used for diagnosis of diabetes outside of pregnancy, but is currently not recommended for screening for GDM. The researchers will also investigate relationships between glucose measured in different samples (venous versus capillary), different fractions (plasma versus whole blood), and using different methods in pregnancy. In a substudy the researchers will investigate: ethnic differences in HbA1c and other glycaemic markers; the contribution of fasting and postprandial glucose handling, diet and ethnicity on HbA1c; and ethnic differences in insulin responses to 75g OGTT in pregnancy. The researchers will invite pregnant women between 16-34 weeks gestation to participate. The research involves one hospital visit for an OGTT. Participants will have venous blood samples taken fasting and at 1-hour and 2-hours, and at the same times finger-stick blood samples will be tested. The researchers will invite women of Black African, Black Caribbean and White European ethnicity to participate in a substudy in which participants will have extra blood taken and a diet assessment. If the hOGTT provides accurate results in pregnancy, using it to perform OGTTs at home would make screening for GDM less expensive and more convenient and may facilitate universal screening for GDM. Understanding ethnic differences in HbA1c will help determine if HbA1c is a reliable screening tool for GDM in our ethnically diverse local population.

The Effect of Different Food Products on Post Prandial Blood Glucose in Pregnant Woman With Diabetes...

Type 1 DiabetesType 2 Diabetes1 more

During pregnancy nutrition demands change and the pregnant woman needs to adjust her food intake and take into consideration the corrected daily recommendations for micro and macro nutrients. Pregnant woman tend to suffer from hyperemesis and this affects their food choice. Amongst pregnant women with Diabetes the glucose balance is extremely important during pregnancy. Glucose balance is a result of correct nutrition and an exact amount of insulin. This delicate balance requires from the pregnant women an ability to perform correct carbohydrate count. Hyperglycemia has already been proven to affect the fetus and the neonatal outcomes. Hypoglycemia may also have a negative effect but the main danger is immediate harm to the mother and therefore to the fetus. For those reasons glucose balance is crucial and demands delicate synchronization of nutrition and insulin therapy.

Study of Betatrophin Levels in Patients With Type 2 Diabetes and Gestational Diabetes and Healthy...

PregnancyGestational Diabetes Mellitus (GDM)1 more

Betatrophin is a newly identified hormone that promotes pancreatic beta cell proliferation, improves glucose tolerance and regulates lipids metabolism. A recent study showed that circulating concentrations of betatrophin doubled in type 1 diabetes. The objective of this study is to investigate the association of serum betatrophin levels with the progression of diabetic retinopathy in patients with type 2 diabetes and the level of betatrophin in gestational diabetes patients and pregnant women.

The Association Between High Risk Pregnancy and Sleep-disordered Breathing

PreeclampsiaGestational Diabetes1 more

The aim of the present study is to establish, using polysomnographic criteria and prospective nature, whether sleep apnea in pregnancy is more prevalent in women with high risk pregnancies including preeclampsia, gestational diabetes, and pre-mature contractions, and to determine the effect of sleep disordered breathing in pregnancy on fetal outcome. The investigators' hypothesis is that sleep-disordered breathing is more prevalent in women with high risk pregnancy compared to those with uncomplicated pregnancy.

Identification of Gestational Diabetes Mellitus Related Urinary Biomarkers Along Pregnancy (From...

Gestational Diabetes Mellitus

Gestational diabetes mellitus (GDM) has many adverse effects on pregnant women and fetuses. At present, no prediction marker for GDM in early pregnancy is accepted. There is still a lack of recognized early predictors. This study was designed to identity valuable biomarkers for GDM.This was a prospective observed cohort study. 140 pregnant women were recruited in early pregnancy, and followed up to 6 weeks postpartum. Glucose challenge test and 75g oral glucose tolerance test were performed after 24 weeks of pregnancy, and GDM was diagnosed according to the latest ADA standard. Urinary samples were collected in the first (<12 weeks), second (24~28 weeks) and third (32~weeks) trimester of pregnancy. Urinary proteomics and metabolomics were analyzed by ultra-performance liquid chromatography tandem mass spectrometry. 15 cases of GDM women and 50 cases of control women were used for longitudinal analysis; 15 cases of GDM women and 15 cases of age matched control women were used for difference analysis.

Role of Adipokines in Glucose Regulation During Pregnancy and in Fetal Development

Gestational DiabetesInsulin Resistance

This study includes 2 phases. During phase 1, pregnant women are followed over the course of pregnancy. The phase 2 is a follow-up of the mother-child dyad at 3 and 5 year after delivery. The purpose of this phase 1 is to : assess the contribution and interactions of adipokines in the development of insulin resistance during pregnancy and gestational diabetes; assess levels of maternal adipokines as determinants of development and fetal growth; determine the genetic variations that influence levels of adipokines and glucose regulation during pregnancy and in newborns. The purpose of this phase 2 is to: identify DNA methylation variations at birth that are predictive of childhood overweight/obesity. identify maternal characteristics associated with DNA methylation variations predictive of childhood overweight/obesity. establish whether the loci predictive of childhood overweight/obesity at birth are still differentially methylated at 5 years of age (samples collected at 5 years of age). identify DNA methylation variations at birth that are predictive of childhood neurodevelopment problems at 3 and 5 years of age.
