Glucose Monitoring During Threatening Preterm Birth in Patients With and Without Gestational Diabetes...
DiabetesGestational4 moreThis study aims to show whether the hyperglycaemic phases following a treatment with glucocorticoids, as well as blood measurements correlated to high blood glucose levels and insulin resistance, vary significantly between patients with and without gestational diabetes mellitus.
Chrono Nutrition (CN) Intervention Program in Gestational Diabetes Mellitus
GDMWorking hypothesis and aims: To asses Chrono Biological factors during the third trimester of gestational diabetes melittus (GDM) with birth weight and related complications. The investigators hypothesize that participants with GDM pregnancies with higher Chrono Biologocal status will be ended with higher birth weight compared to participants with GDM pregnancies with lower status. In addition, the investigators hypothesize that the Chrono Nutritional intervention program will contribute to the reduction of the rate of birth weight above percentile 90 compared with the participants with GDM in the control group.
Investigation of Mechanisms for Transmission of Impaired Glucose Metabolism in Infants Exposed to...
PregnancyGestational Diabetes MellitusThis proposed study; Investigation of mechanisms for transmission of impaired glucose metabolism in infants exposed to diabetes in utero, will test the overarching hypothesis that impaired maternal substrate oxidation (metabolic inflexibility) and placental lipotoxicity are characteristics of diabetic pregnancies and in utero development within these conditions programs a metabolically inflexible phenotype in the offspring.
Effect of DCC on Neonatal Jaundice and Blood Gas Analysis in Infants Born to GDM Mothers
Gestational Diabetes MellitusNeonatal Hyperbilirubinemia1 moreEvidence for benefited newborns following delayed cord clamping (DCC), including increasing hemoglobin and hematocrit levels, improving iron stores, and decreasing need for blood transfusion and incidence of intraventricular hemorrhage, in term or preterm infants led the American College of Obstetricians and Gynecologists (ACOG) to recommend a delayed cord clamping at least 30-60 seconds in vigorous term and preterm infants at birth. Although DCC has been found to be beneficial to infants, the additional blood provided by DCC could increase the incidence of jaundice that requires phototherapy and the hyperbilirubinemia, and the time prolonged by DCC might jeopardize timely resuscitation efforts, if needed. The acid-base status in umbilical cord blood at birth reflects the newborn's aerobic and anaerobic intrauterine metabolisms and is an objective measure of the fetal exposure and response to hypoxia during labour. Gestational diabetes mellitus (GDM) is a condition in which glucose intolerance develops during pregnancy. It has been estimated in 2009 that nearly 7% of pregnancies are complicated by diabetes and approximately 86% of these cases represented women with GDM. The Hyperglycemia and Adverse Pregnancy Outcome study (HAPO) revealed that the infants of diabetic mothers (IDMs) are at increased risk of neonatal hypoglycemia, hyperbilirubinemia, shoulder dystocia, and birth trauma. And newborns to diabetic mothers are at increased risk of neonatal respiratory distress syndrome (RDS) and hypoxia, a major cause of admission in neonatal intensive care units. There is little direct evidence on the implementation of delayed umbilical cord clamping in the risk group of IDMs. Therefore, it no clear that the effectiveness and impairment of DCC in IDMs. Therefore, the investigators conducted a prospective study in performing DCC in the infants of diabetic mothers versus the newborns with early cord clamping (ECC) to assess the effect of DCC on neonatal bilirubin levels, hyperbilirubinemia incidence, acid-base status and hypoxia in IDMs.
Risk for Ketonaemia in Type 1 Diabetes Pregnancies With Sensor-augmented Pump Therapy
Pregnant Women With Type 1 DiabetesThe ROKSANA study is an open-label crossover RCT with the aim to evaluate whether sensor-augmented pump therapy (SAP) with predictive low glucose suspend technology is associated with an increased risk for ketonaemia during type 1 diabetes pregnancies.
Hearing Screening Outcomes of Two Screening Tests in Newborns of Gestational Diabetic Mothers
Gestational DiabetesHearing LossIn this study, the investigators have aimed to investigate whether GDM is a risk factor for hearing impairment in newborns. To the investigators knowledge, this study is the first prospective, controlled study on this subject.
The Metabolic Profile in Intrahepatic Cholestasis of Pregnancy and Diabetes Mellitus
Intrahepatic Cholestasis of PregnancyGestational Diabetes MellitusICP is known to cause abnormal bile acid homeostasis and to be associated with an increased risk of diseases of the biliary system in later life. There have been small studies (Dann et al. 2006; Wójcicka-Jagodzińska et al. 1989) suggesting that it causes dyslipidaemia (raised lipids) and impaired glucose tolerance in pregnancy. However the underlying mechanisms of these abnormalities is not known. Similarly the influence of cholestasis on fetal metabolism is not known, and nor is the role of the placenta. It is also not known whether women with ICP have a predisposition to abnormal lipid and glucose homeostasis when they are not pregnant. GDM is characterized by raised plasma glucose levels in pregnant women (in the absence of pre-pregnancy diabetes mellitus). This condition is associated with large-for-gestational age babies and obstructed labour. Women with GDM have increased risk of subsequent type 2 diabetes mellitus, and if they have this condition in a subsequent pregnancy there is an increased risk of stillbirth. This work is important to understand the causes of the metabolic abnormalities associated with ICP and GDM. If we demonstrate abnormal lipid and glucose profiles, these may be of relevance to the fetal complications of both disorders. It will also be of relevance to the future health of affected women and their children.
Postpartum Glucose Tolerance With Levonorgesterel IUD Use in Women With Recent Gestational Diabetes...
Gestational DiabetesGlucose Intolerance2 moreThe study is being done in order to gain information on the most suitable types of birth control in women who recently had gestational diabetes, or diabetes diagnosed during pregnancy. The intrauterine device (IUD) is a highly effective form of birth control. It is inserted into the uterus and prevents pregnancy for either 5 or 10 years, depending on the type of IUD (hormone-releasing or copper). The hormone-releasing IUD works for 5 years and releases a hormone called a progestin into the uterus. The copper IUD contains no hormones and works for 10 years. The IUD is an excellent form of birth control postpartum, but it is unknown if the hormone-releasing IUD will affect blood sugars and increase a woman's risk of becoming diabetic when she's not pregnant. The hypothesis is that the hormone-containing IUD will NOT increase blood sugars, so women who use the hormone-containing IUD will have similar blood sugars to those who use the copper IUD or have had their tubes tied (no hormones).
Afamin in Gestational Diabetes Mellitus
Gestational Diabetes Mellitus in PregnancyThis study includes pregnancies in 11 to 14 th gestational weeks. Investigators will sample maternal plasma in the first trimester and analyze maternal plasma afamin values. All these women will then be screened by two step OGTT. Investigators will compare afamin levels in GDM and control groups.
The Relation Between Vitamin D and Gestational Diabetes Mellitus
DeficiencyVitamin D2 moreGestational diabetes mellitus (GDM) is defined as any degree of glucose intolerance with the onset or first recognition during pregnancy. The prevalence of GDM varies from 1-14% due to its variability worldwide, depending on the ethnicity, race, and the diagnostic criteria being applied by each country. In addition to this, approximately 7% of all pregnancies are affected by GDM, ending up more than 200,000 women with GDM per year. A recent study of literature research indicated that Middle East and North Africa had the highest prevalence (median, 12.9%) while Europe had the lowest prevalence (median, 5.8%) in the world. In Turkey the prevalence of GDM ranges between 4-10%, based on the reports in different studies. As a growing health concern, GDM has been associated with short and long-term detrimental health outcomes for women and their offspring. Maternal adverse effects of GDM are preeclampsia, elevated risk of development of hypertension, type 2 diabetes mellitus (T2DM), urinary tract infection and comorbidities following delivery. Macrosomia, neonatal jaundice, birth trauma, respiratory distress syndrome, hypoglycemia are included in short term consequence for the neonates whereas risk for development of impaired glucose tolerance, T2DM, obesity, vascular disorders are long term adverse effects on infant's health. The known risk factors for GDM include family history of T2DM, maternal overweight and obesity, advanced maternal age, history of GDM, having macrosomic infant previously, prior fetal death, and race/ethnicity. In addition to these risk factors, recent studies have been suggested that maternal vitamin D deficiency may be associated with a higher risk of GDM. Vitamin D deficiency during the pregnancy has been associated with adverse outcomes for the pregnant women, such as gestational diabetes mellitus, urinary tract infection, preeclampsia, caesarean section during labour [25]. Furthermore, infants born to mothers with lower vitamin D levels have been found to be associated with elevated risk of small for gestational age, low birth weight in the neonatal period, increased risk for cardiovascular disease, respiratory illnesses, type 2 diabetes mellitus in childhood and adulthood. The aim of this study was to compare the serum 25(OH)D levels of women with and without gestational diabetes mellitus (GDM) and identify the serum 25(OH)D level associated with GDM during pregnancy.
