Active clinical trials for "Pregnancy in Diabetics"

Hypothesis: Patients with Gestational Diabetes Mellitus (GDM) have a high risk to develop complications during pregnancy, puerperium and in the newborn. At present there are not scientific evidences about the optimal distribution of meals in the medical nutrition therapy (MNT) and their relationship with glycemic control. Aim: To explore and compare ketonemia and glycemic profile in patients with GDM that follow a MNT distributed in 6 or 3 meals. Besides, we want to explore the differences between both treatments in glucose dynamics. Methods: The study design is a randomized, crossover and multicentric trial. A sample of 10 patients with GDM will be recruited in the Department of Endocrinology and Nutrition from both centres. In a randomized manner patients will follow the conventional treatment (a carbohydrate-controlled diet distributed in 6 meals: 3 main meals and 3 snacks) and the intervention treatment (a carbohydrate-controlled diet distributed in 3 meals: breakfast, lunch and dinner). They will be randomized to begin with one of the two treatments, and after two weeks they will be switched to the other treatment. Patients will wear a blinded continuous glucose monitoring device (iPro2-TM, Medtronic) during the entire study period. Inclusion criteria: Women with GDM diagnosed in 24-28 weeks. Age 18-40 years. Pregnancy age of 28-32 weeks. Caucasian. Body mass index ≤ 35 Kg/m2. Exclusion criteria: Unability to understand the dietary recommendations and/or to perform self-management of glycemia, ketonuria or ketonemia. A low adherence to MNT. Problems with written and/or oral communication. Presence of comorbidities other than obesity, hypertension and dyslipidemia. Insulin-need criteria within 3 first days of the beginning of the study (fasting glucose ≥90mg/dL, postprandial glucose 1-hour ≥140mg/dL). Clinical and sociodemographic variables will be assessed. Dietary records and blood samples will be collected. Daily basal ketonuria and ketonemia before each meal will be assessed. Glycemic profile will be collected with a blind-sensor during the four weeks of the intervention study. Generalized linear model analysis will be performed. Statistical power will be 80% and significance level will be set at 0.05. Written informed consent will be collected from all participants.

Maternal diabetes in pregnancy can negatively impact fetal well-being and contribute to adverse pregnancy outcomes. Much of the morbidity associated with diabetes in pregnancy can be minimized with tight glucose control. A number of studies in non-pregnant populations have highlighted the feasibility, acceptability and efficacy of text messaging interventions for improving diabetic compliance and control. This study will investigate whether a text messaging intervention is feasible and effective in an urban, diabetic, obstetric clinic and whether this intervention can improve compliance with diabetes care, glucose control and pregnancy outcomes. The study will also assess satisfaction with the intervention itself.

The prevalence of gestational diabetes mellitus (GDM) has been progressively increasing. It is important to recognize and treat GDM to minimize the risk of maternal and neonatal complications. Multifaceted professional interventions are effective in the management of GDM and mobile healthcare can be an effective approach. The purpose of the current study was to develop and evaluate a model for prevention and management of GDM using mobile healthcare. Subjects with no previous history of diabetes, who were diagnosed with GDM during 24-28 weeks of gestation, were randomly divided into a conventional management group and a mobile management group. The conventional mangement group received conventional GDM management and could freely use the mobile healthcare application. The mobile management group received mobile healthcare services including tailored mobile coaching. The effectiveness of the management using the application were evaluated through the result values of the laboratory tests, anthropometric measurement performed during the study period and perinatal outcomes.

Our aim was to investigate and compare placental elasticity by using Shear wave elastography (SWE) in patients with gestational diabetes mellitus (GDM) with and without insulin to non-diabetic controls. This prospective study included 319 pregnant patients. Three groups were created as follows: Group 1 (n= 79, GDM with insulin therapy), Group 2 (n=90, GDM with only diet) and Group 3 (n= 150, healthy controls) All patients were above 36 gestational weeks with anterior placenta. Totally six measurements including the central and peripheral parts (right, left) of the placenta both from maternal and fetal sites were obtained with SWE. Demographic, obstetrics, fetal and perinatal features were also compared. Receiver operating characteristic analysis was plotted and cut-off of elastographic velocity values were noted

In this study the effect of the Health-Promoting Lifestyle Education Program (HPLEP) provided to women with GDM on maternal and neonatal health was investigated. The education program and also usual care applied to the intervention group, only usual care applied to the control group.

Diabetes during pregnancy can be a challenging circumstance requiring extensive patient learning and self-care. The purpose of this study is to develop and pilot test a patient-centered diabetes education and self-care tool using text messaging to provide supportive messaging and education to underserved women with a pregnancy complicated by diabetes.

Diabetes during pregnancy is a challenging clinical situation requiring substantial patient engagement. The investigators have developed a novel early-phase tool, called SweetMama, that incorporates educational, motivational and supportive elements to positively impact maternal health behaviors. This phase of work involves develop an optimized version of SweetMama via a 2-step sequential process of in-depth usability and feasibility testing. First the investigators will conduct focus groups and individual usability testing followed by refinement of SweetMama based on participant input. Next, the investigators will conduct feasibility testing via a pilot randomized trial to determine acceptability, feasibility, and pilot procedures for a fully powered larger trial.

Glucose control during labor is important for both fetus and mother. During labor and delivery, the goal is to maintain the sugars in the normal range as safely as possible as increased blood sugars 4-6 h prior to delivery leads to increased rates of hypoglycemia in the neonate. Neonatal hypoglycemia is a risk for the offspring of pregnant women with diabetes and occurs when fetal pancreatic hyperplasia is acutely stimulated by a high fetal glucose level derived from maternal hyperglycemia during labor. The maternal blood glucose level during delivery is a predictor of the neonatal blood glucose level. Modern continuous glucose monitoring (CGM) systems can capture the direction and magnitude of short-lived changes in interstitial glucose levels and are therefore useful for assessing glucose variability more accurately than self-monitoring blood glucose (SMBG) measurements. Indeed, it has already been demonstrated that intermittent blood glucose monitoring underestimates the number of hyperglycemic events, because blood glucose excursions can peak at different times of day. CGMs can help identify glycemic patterns in pregnancy, obtain and maintain glucose targets, and reduce hypoglycemia. Strict glycemic control during labor and delivery may reduce the risk of neonatal hypoglycemia. Two groups have reported on the use of CGM in type 1 diabetics during labor in small pilot studies. Another study looked at effects of maternal glucose levels in insulin-treated women during labor and delivery (2 to 8 h before birth) and resultant neonatal hypoglycemia. The researchers found that maternal hyperglycemia before delivery was correlated with neonatal hypoglycemia. Although more studies are needed, CGM use has promise as a therapy to improve outcomes in pregnancies associated with diabetes. In this study, the investigators plan to explore whether the use of blinded glucose monitoring during labor, delivery, and early postpartum supplementary to normally monitored plasma glucose measurements in women with gestational diabetes (GDM) would provide useful information to improve glycemia during labor in this diabetic population. All CGM data will be masked and therefore not available to participants, clinicians, or researchers at the time of delivery. Participants otherwise will receive standard clinical care. The blinded glucose monitoring data on glycemia throughout labor and post-delivery will be retrospectively assessed.

When women with diabetes become pregnant it is particularly important to control blood sugar levels to prevent complications. Women are advised to test their blood glucose levels seven times a day and to attend antenatal and diabetes clinics every 1-2 weeks throughout the pregnancy. For those living in rural areas in the North and West of Ireland getting to a hospital specialising in the management of diabetes and pregnancy on such a regular basis can be a challenge. Telemonitoring provides a possible solution to this problem by allowing patients to monitor their vital signs at home and transmit the information via telephone to their healthcare provider. If women could be safely monitored remotely for every other appointment it would mean that they would only need to visit the hospital once a month on a routine basis but with the option of attending the hospital if the remote telemonitoring indicated that this were necessary. The aim of this study is to assess the feasibility and the acceptability of using remote telemonitoring facilities between antenatal women with gestational diabetes and the diabetes team and the possibility of replacing alternate diabetic review clinics with remote telemonitoring. In addition this study will explore the feasibility of running a full randomised control trial of this topic. Women will be asked to monitor their blood sugar levels seven times a day which is part of usual care. However those in the remote telemonitoring group will be asked to measure their blood sugar using a meter that can transmit the results via a telephone line and to transmit them weekly. They will also be asked to measure their blood pressure and weight weekly and to download these results weekly for a health care professional to review. These results will be reviewed on a weekly basis by a health care professional who will contact the patient if necessary to discuss the results. Women will be followed-up from the date of diagnosis through to delivery. Both staff and patients will be asked to give their views on the safety and acceptability of remote telemonitoring through questionnaires, focus groups or interviews. The management decisions made on reviewing the intervention group in clinic and reviewing remote telemonitoring results will also be recorded. In order for remote telemonitoring to be a viable replacement for clinic review it must allow health care professionals to make comparable management decisions. Clinical data will be collected in order to provide descriptive statistics for those who take part and to ensure that this information could be collected in any future Randomised Control Trial (RCT) looking at this topic.

The randomized controlled trial (RCT) recruits pregnant women with de novo diagnosis of gestational diabetes. Women bearing a singleton pregnancy are randomized into four arms: DHA, oat, oat plus DHA, and placebo. The primary outcomes are cord blood leptin concentration in the newborns and maternal fasting glucose levels at 8 weeks post-intervention.
