Filter by: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.
Insulin is the standard treatment for the management of type 2 diabetes in pregnancy, however despite treatment with insulin, these women continue to face increased rates of adverse maternal and fetal outcomes. The investigators hypothesize that metformin use, in addition to treatment with insulin, will help with blood sugar control, lower the dose of insulin needed, lower weight gain, and improve baby outcomes.
Justification: Intrauterine exposure to type 1 or type 2 diabetes increase the risk of macrosomia (35 % to 50 % versus 10 % in general population) despite a good glycemic control. The consequences are : shoulder's dystocia, lung immaturity, caesarean section, neonatal hypoglycaemia and a high frequency of obesity and metabolic disorders in adults. The mechanisms of macrosomia are unclear; chronic hyperglycemia and subsequent hyperinsulinaemia observed during the diabetic pregnancy might explain only partially the fetal weight. Considerable interest has been generated over the last decade on the lipids and fatty acids alterations in diabetes pregnancies. Change in lipoproteins metabolism have been described associated with macrosomia. Maternal nutrition before and during pregnancy plays an important role in fetal growth and subsequent development of an increased susceptibility to obesity and diabetes in later life. Main objective: Looking for an association between maternal and fetal blood lipid parameters and birth weight and body fat in a context of type 1 or type 2 diabetes. Secondary objectives: - Identify lipid markers associated with fetal macrosomia. - Analyze the placenta by measuring the expression of genes implicated in the storage and the transfer of fatty acids. - Analyze and compare the expression level of placental genes subjected to parental imprinting and validated in animal models.
Thesis Infants of diabetic mothers are at high risk to develop hypoglycemia after birth. After birth, glucose and ketone bodies are the main substrates of brain energy. Under normal condition, the adrenergic response seen immediately after birth suppresses insulin release and stimulates glucagon secretion which enhances gluconeogenesis and ketogenesis. An inversion of the insulin/glucagon ratio is seen soon after birth as a normal, physiologic phenomenon. Consequently, a post delivery glucose nadir is reached between 30 to 90 minutes after birth, followed by a spontaneous recovery before 3-4 hours of age. In infants of diabetic mothers, this inversion of the ratio is postponed and a more profound and sustained hypoglycemia is seen. Early feeding is of great importance to diminish the severity and incidence of hypoglycemia. But, if despite an appropriate calorie intake, low levels of sugar are seen, an intravenous infusion of glucose should be commenced. In case that IV glucose is not effective or can't be supplied immediately, intramuscular glucagon is a therapeutic alternative. We hypothesize that a single intramuscular injection of glucagon together with the appropriate oral intake of nutrients is a safe and an effective alternative to the IV infusion of glucose alone in the treatment of hypoglycemia in term infants of diabetic mothers. Methods Appropriately grown or large for date, term infants of insulin treated diabetic mothers, with no other known medical problems, are potential candidates for our study. Hypoglycemia will be defined as serum glucose level lower than 45 mg%. Infants of diabetic mothers will arrive to the nursery and immediately receive early feeding before 30 minutes of life. At that time, glucose will be checked. If glucose level is lower than 45 mg%, treatment with IV glucose or IM glucagon will be initiated. Glucose will be checked every hour for 4 hours and then every 3 hours (before each meal) for the next 20 hours. In case blood glucose level is lower than 20 mg% or falls below 45 mg% despite glucagon treatment, IV glucose will immediately be instituted. Our aim is to check that IM Glucagon is as good as IV glucose in the treatment of hypoglycemia in infants of diabetic mothers. We will compare glucose levels after treatment with IV glucose and IM glucagon, the time till normalization of glucose and full feeding is achieved and the number of hospitalization days in both groups.
The purpose of this study is to determine whether insulin resistance might affect the pathogenesis of hypertensive disorders in pregnancy since midtrimester. Furthermore, markers of vascular and placental injuries, of oxidative stress and inflammation will be evaluated.
