Active clinical trials for "Diabetes, Gestational"

For women of reproductive age, the overall postpartum weight retention (weight gain between pregnancies) plays a significant role in long-term obesity. With 20% of women retaining ≥ 5 kg at 12 months postpartum, the risk of developing conditions, such as gestational diabetes mellitus (GDM), metabolic syndrome (MS) and subsequently diabetes and cardiovascular diseases, is substantially increased. In post-GDM mothers (women who had GDM in their recent pregnancy), postpartum weight retention is also an essential predictor of future diabetes. Recent studies have identified the impact of circadian rhythms (influencing sleep/wake cycles) and diurnal rhythm of eating (when and how often calories are consumed over a 24h period) on cardio-metabolic disorders. In women, one remarkable feature of the postpartum period is an 'externally imposed' circadian misalignment of both sleep and eating rhythms, because most babies take several weeks to months to establish their daily pattern of activity and feeding, which is particularly relevant for breastfeeding women, as the responsibility is generally on the mother. The overarching goal of this project is to explore the interplay between the diurnal rhythm of eating, circadian and metabolic parameters in humans. The potential postpartum effects of circadian disruption will be unraveled in women who had GDM during their pregnancy and those with an uneventful pregnancy. These women are subject to a circadian misalignment due to their 'externally imposed' changes in sleep/wake cycles and eating times in the postpartum period. With a comprehensive approach combining molecular characterization of in vivo and in vitro circadian clock parameters along with metabolic, endocrine, transcriptomic, and lipidomic studies, the investigators will assess if eating duration and/or circadian misalignment impact on circadian clock parameters of postpartum women in a prospective cohort of 6 months.

This study will look at blood sugar levels in pregnant women who have been given a glucocorticoid (steroid) medication to enhance fetal lung maturity. The findings will help determine the likelihood, predictive value, adverse effects, response of patients diagnosed with gestational diabetes and time course of blood sugar elevation following steroids.

Hyperemesis gravidarum (HEG) is not only nausea and vomiting of pregnancy, but it is also a clinical syndrome including endocrine and metabolic complications. Recently, some investigators have been begun performing researches related to the development of gestational diabetes mellitus (GDM) in pregnant women with HEG because they think about those metabolic and endocrine complications of HEG.In the literature there are few studies assessing how HEG has effects on GDM or 75 gram oral glucose tolerance test (OGTT). So the investigators aim to evaluate the effects of HEG on 75 gram OGTT.

High pre-pregnancy body mass index (BMI) and excessive gestational weight gain (GWG) are associated with many unfavourable maternal and neonatal outcomes. Adherence to lifestyle recommendations could be a major determinant of the efficacy on preventing unfavorable outcomes, namely among overweight/obese women. Previous studies investigated adherence to specific dietary patterns and their effect on pregnancy outcomes; however, no study has investigated adherence among overweight/obese pregnant women and its effect on the onset of several maternal-neonatal outcomes. This study aimed to determine whether the prescription of a lifestyle program, consisting of a customized low-glycemic index (GI) diet and a physical activity program, in overweight and obese women could affect the occurrence LGA babies. It also aimed to determine whether this kind of prescription influences the adherence to healthier eating habits, and how this, in turn, can influence the occurrence LGA.

The objective of the study is to investigate the effect of stress on glucose tolerance during pregnancy. The main objectives of the study are to investigate if various measures of stress (stressful life events, the perceived level of stress and the cortisol or copeptin concentrations) differ between pregnant women with and without gestational diabetes during the end of the second/beginning of the third trimester when presenting for their routine glucose tolerance testing. Secondary objectives are the link between these different stress measures and the routinely measured fasting and stimulated glucose levels during the oral glucose tolerance test.

The aim of the present study is verify glycated hemoglobin (HbA1c) and HOMA behavior in pregnant women with gestational diabetes or chronic hypertension after an aerobic training in cycle-ergometer. The sample is composed by 64 pregnant and sedentary women, 20 weeks' pregnant. Two experimental groups (gestational diabetes and chronic hypertension, n = 16 each) will perform a low-intensity aerobic training in cycle-ergometer, three times/week, for 45 minutes each session. Two control groups (gestational diabetes and chronic hypertension, n = 16 each) will perform an unique session/week of relaxation and stretching. Outcomes: first ventilatory threshold, HbA1c,HOMA, type of delivery, weight and height of the newborn.

Immediate postpartum screening for diabetes mellitus in women with gestational diabetes The objective of this study is to determine if screening for type 2 diabetes can be done 24 hours after delivery, versus 6-12 weeks postpartum, in recently delivered women having been diagnosed with gestational diabetes requiring medication therapy in the antecedent pregnancy.

This is an observational, prospective cohort study describing pregnancy outcomes in women with pre-existing (prior to pregnancy) type 2 diabetes who have been exposed to any formulation of exenatide during pregnancy. The pregnancy registry will compare the occurrence of the pregnancy outcomes of interest with those collected from a prospective group of women with pre-existing type 2 diabetes who have been exposed to one or more antidiabetic medications other than exenatide during pregnancy. Insulin exposures are acceptable in both groups but must be in addition to one or more other antidiabetic medications in the non-exenatide group. The primary study objective is to evaluate the percentage of major birth defects (i.e., those that caused significant functional or cosmetic impairment, required surgery, or were life-limiting) following use of exenatide during pregnancy for treatment of type 2 diabetes compared to the percentage of major birth defects following use of one or more antidiabetic medications other than exenatide during pregnancy for treatment of type 2 diabetes. The secondary objectives of the Exenatide Pregnancy Registry are to evaluate the percentage of other adverse pregnancy outcomes (e.g., spontaneous abortion, stillbirth, preterm birth) and any potential impact of exenatide use during breastfeeding among pregnancies or births in women who used exenatide for pre-existing type 2 diabetes: This study is being conducted in the United States (US). Enrollment in the Registry is voluntary. The Exenatide Pregnancy Registry is sponsored by AstraZeneca and is managed by INC Research, LLC. The scientific conduct and analysis of the Registry is overseen by a Registry Review Committee (RRC) consisting of experts in maternal and fetal medicine, teratology/genetics, epidemiology, type 2 diabetes in pregnancy and/or pediatrics.

Background: Remote monitoring (RM) is a new screenings- and or diagnostic tool in healthcare. In 2015, the PREMOM study (Pregnancy Remote Monitoring), in which patients with gestational hypertensive diseases did received a RM prenatal follow up, has started. The first results showed an added value of RM in the prenatal follow-up. Due to these results, a RM program for pregnant women with gestational diabetes mellitus (GDM) will be developed and evaluated. Protocol: Women (at risk of) GDM will be included in this study. They receive a iHealth Align (a glucose monitor) and associated glycemiestrips. The app of iHealth will be downloaded on the pregnant women's Smartphone to collect the data and to send them to the researcher in the hospital. The women is asked to perform four glycemie controls/day (sober and two hours after every mail) with the received glucose monitor. The monitor is connected via Wi-Fi and Bluetooth with the computer of the researches who controls and evaluated these data. Additionally, the pregnant women has to check daily her body weight with a weight scale of her own. They have to upload these data manually in the app on her smartphone. When the pregnant women has an prenatal consultation, an overview with the data will be send to the responsible gynecologist. The gynecologist will also be alarmed when the pregnant women has three abnormal values at the same moment of the day (ex. Every morning after breakfast). When necessary, advice among life-style can be given or a referral to an endocrinologist can be made. The researches will not perform interventions by herself, only the responsible doctor can do this. By analyzing the patients parameters when she's at home, a better vision can be achieved of the health of the mother and the child. This study will be conducted as a first research to get a better insight in the added value of RM in pregnancies complicated with GDM.

A prospective, multicenter, randomized controlled trial including about 60 Gestational Diabetes Mellitus patients (GDM) in Beijing will be included to evaluate the effectiveness and safety of nutrition product (SANZ®KINGWILL) in GDM patients, based on Continuous Glucose Monitoring (San MediTech CGM-303).
