Active clinical trials for "Diabetes, Gestational"

Diabetes in pregnancy or gestational diabetes (GDM) is a condition that, if left untreated, may lead to complications for the mother and her baby. It is still not known which is the best method to diagnosis GDM. The goal of this study is to compare three well-accepted methods for diagnosis of GDM (using either 75 g or 100 g in the glucose tolerance test) and determine which method is the easiest and least expensive to use in relation to the reference method used over the last 20 years. The goal is to see if they can equally predict the healthy outcome of the pregnant mother and her newborn.

This study is designed to determine if a postnatal lifestyle intervention will lead to weight reduction over a 12 month period post-delivery in women who have been diagnosed with gestational diabetes mellitus and who have a BMI greater that 25 compared to women who receive routine care.

Gestational diabetes mellitus (GDM) increases the risk of adverse pregnancy outcome and developing type 2 diabetes after delivery. It is well recognized that behavioral intervention is effective in preventing type 2 diabetes in high risk population. Recently, some studies showed that exercise, dietary and weight control reduced the risk of developing GDM in obese/over weight women or in women with GDM history. With the increasing use of smartphones, mobile applications (APPs) can be applied in the education and management of chronic diseases, including diabetes. Therefore, the investigators will conduct a multi-centered, two-armed, open-labeled, randomized controlled trial to evaluate whether early lifestyle intervention with a mobile APP can prevent the occurrence of GDM in pregnant women who are at high risk of this disease. The investigators hypothesis that behavioral intervention from the first trimester of pregnancy with mobile APP that incorporates nutrition, exercise and phycological support will: Reduce the risk of developing GDM in pregnant women with risks of GDM. Improve the pregnant women's adherence of behavioral intervention and their satisfaction of prenatal medical care.

Pelvic girdle pain and gestational diabetes mellitus are experienced in similar trimesters of pregnancy. The aim of this study is to examine the effect of gestational diabetes mellitus on the occurrence of pelvic girdle pain and the severity of symptoms of pelvic girdle pain in pregnant women.

Glucose intolerance and gestational diabetes are common complications of pregnancy. Their prevalence varies worldwide secondary to differences in screening practices (one-step versus two-step approach) and population characteristics (increased maternal age, body mass index, ethnicity). Gestational diabetes mellitus is associated with increased incidence of macrosomia, operative vaginal delivery, shoulder dystocia, cesarean delivery, metabolic complications in the newborn and long-term risk of developing type II diabetes mellitus (HAPO 2008). Early diagnosis and management of gestational diabetes mellitus, including dietary advice and insulin, improves maternal and fetal outcomes (Crowther 2005, Hartling 2013). Various strategies have been tested prenatally to detect those fetuses that might be adversely affected by gestational diabetes mellitus. For instance, the abdominal circumference measurement during routine fetal biometry was used successfully to identify pregnancies with a higher risk of fetal macrosomia (Schaefer-Graf 2003, De Reu 2008, Rosati 2010). In recent years, the fetal interventricular septum thickness, as detected by two-dimensional ultrasound, was shown to be significantly thicker in the presence of gestational diabetes mellitus, independently of maternal glycemic control, when compared to pregnancies with no gestational diabetes mellitus (Ren 2011, Garg 2014). Current guidelines focus on normalisation of maternal blood glucose concentration. Thus far no study has addressed whether measurement of the fetal interventricular septum thickness can predict adverse pregnancy outcome in euglycemic women with gestational diabetes mellitus.

The objective of this study is to determine the most appropriate and effective approach for the diagnosis of gestational diabetes mellitus (GDM) among pregnant women receiving focused antenatal care at Moi Teaching and Referral Hospital (MTRH). This will be done through performing a random blood sugar, fasting blood sugar, 1 hr/2hr glucose tolerance test, and HbA1c on all participants who meet eligibility criteria and provide written, informed consent. The specific research question is: what is the most appropriate screening and diagnostic strategy for patients receiving antenatal care at MTRH?

This is an observational study at the Obstetrical outpatient clinic at Stavanger University Hospital, Norway. The purpose of the study is to compare glycated albumin and glycated hemoglobin (HbA1c), both markers of "long-term blood sugar" with oral glucose tolerance test (OGTT). The OGTT is a screening test for gestational diabetes, a condition that increases risk of adverse pregnancy outcome for mother and child. The risks are reduced with good glycaemic control throughout pregnancy, therefore, it is important to screen for gestational diabetes.

India is one of the diabetes capitals in the world. Indians are susceptible to develop diabetes at a younger age and at a lower BMI compared to Europeans. Current prevention strategies focus on reducing risk in those with the established disease or risk factors. The Developmental Origins of Health and Disease (DOHaD) hypothesis suggests that chronic non-communicable diseases (NCDs) are programmed by disturbances in maternal and fetal undernutrition. This offers an alternative primordial prevention strategy to reduce NCDs in future generations by improving health and nutrition of young women. Previous work in the Diabetes Unit, KEM Hospital, Pune has described the role of maternal micronutrients affecting 1-Carbon metabolism in the fetal programming of diabesity. In this application, the investigators offer to study other pathways of fetal programming i.e. maternal hyperglycemia and gestational diabetes mellitus (GDM) using an 'OMICs' approach. It is believed that epigenetic changes may be the main driver of programming. The investigators hypothesize that offspring of diabetic mothers will have different epigenetic signatures in cord blood and placenta compared to offspring of non-diabetic mothers. The investigators propose to study the effect of gestational hyperglycemia on newborn epigenetic signatures using the most appropriate technologies available and associate them with the underlying genotype. This will be performed on cord blood of 150 offspring of women with GDM and compared with a similar number of offspring of non-diabetic mothers recruited at Pune. The differentially methylated regions (DMRs) identified will then be validated by pyrosequencing in ~300 stored GDM cord blood samples in Pune. The investigators from Pune will also validate these markers in 200 newly recruited offspring of GDM and 200 controls from a different cohort in Punjab which has a different diet and lifestyle. The DMRs will also be validated in placental samples from both Pune and Punjab. The investigators will further test the stability of these markers and their associations with phenotype in a follow-up study of offspring of GDM mothers in upto 500 individuals. The investigators will compare the findings with the DNBC-GDM cohort in Denmark, allowing for differences in age, genetic make up, nutritional status and lifestyle. This study will help understand contribution of maternal diabetes to the current epidemic of diabesity and its molecular basis.

MySweetHeart Cohort is an observational study to assess the effect of gestational diabetes mellitus (GDM) on early life offspring's cardiovascular health. The primary objective is to assess the effect of GDM on the surrogate markers of cardiovascular disease (CVD) at birth (left ventricular mass index and subclinical atherosclerosis). The secondary objective is to assess the effect of GDM on the cardiovascular structure and function during the fetal period and neonatal adverse cardiovascular risk factors. The main hypothesis is that offspring of women with GDM have a larger LVMI and a larger cIMT at birth (primary outcomes) compared with offspring of women without GDM. Further, other hypotheses are that offspring of women with GDM have more foetal cardiovascular alterations and adverse neonatal cardio-metabolic risk factors (secondary outcomes) compared with offspring of women without GDM. My SweetHeart Cohort is linked to MySweetHeart Trial, a randomized controlled trial assessing the effect of a multidimensional interdisciplinary lifestyle and psychosocial intervention to improve the cardio-metabolic and mental health of women with GDM and their offspring. The principal investigators of this trial are Prof Jardena Puder and Dr Antje Horsch from Lausanne University Hospital.

Multiple studies have demonstrated a very low prevalence of women meeting physical activity and weight gain recommendations during pregnancy. Additionally, previous Blossom Project studies have shown that when pregnant women engage in a 20 minute walk each day, they spend significantly more time sitting in addition to longer bouts of sitting resulting in increased total sedentary time. We are going to test which method works best to decrease sitting time, and how those methods effect metabolic parameters such as insulin resistance and blood glucose. This study will consist of three groups, each utilizing a commercially available fitness tracker, Fitbit. Group 1 (SR): will reduce sedentary time by interrupting prolonged sitting. Group 2 (WALK): will reduce sedentary time via walking. Group 3 (UC): will continue on with their normal daily routine; usual care.
