Filter by:Through complex hormonal pathways, insulin resistance can lead to the activation of the sympathetic nervous system, and vice versa. Schobel et al. showed that in PE patients, mus-cle sympathetic nerve activity (MSNA) is increased compared with normotensive pregnant and non-pregnant women. Studies assessing heart-rate variability and plasma noradrenalin concentrations also suggest increased sympathetic activity in PE. It has been hypothesized that sympathetic over-activity is a precursor of PE, normally compensated for by vasodilating mechanisms, but resulting in PE when the mechanisms fail. In addition to sympathetic activity, various markers of inflamma-tion are also associated with reduced insulin sensitivity, suggesting that chronic sub-clinical inflamma-tion could be part of the insulin resistance syndrome. The role of sympathetic over-activity and inflammatory markers in gestational diabetes has not been investigated
Ten to 50% of women with gestational diabetes (GDM), or glucose intolerance first recognized during pregnancy, develop diabetes within 5 years after delivery. Although intensive interventions can reduce diabetes incidence in women with impaired glucose tolerance, it is unknown if such strategies would be effective in women with GDM. Women with recent GDM, even though no longer pregnant, face significant barriers to lifestyle modification, including caregiving responsibilities and low perception of risk. Web-based programs can reinforce physical activity through visual feedback of pedometer output, tailored messaging, education, and on-line communities. Such a program is currently available for adults with chronic disease and is led by Dr. Richardson, a co-PI on this application. Using data from focus group and survey work conducted by Dr. Kim, the other co-PI, this program can be modified to women with recent GDM. For Specific Aim 1, we propose to adapt a chronic disease web-based pedometer program to women with recent GDM. For Specific Aim 2, we propose to conduct a pilot and feasibility study of the program. The intervention will last 12 weeks.
No dietary strategies have been designed and proved for Mexican pregnant women with diabetes. This is a randomized clinical trial of pregnant women with pregestational type 2 diabetes and gestational diabetes that were followed every two weeks until labor to assess the impact of the MNT program on metabolic control, maternal and fetal nutritional status and cost effectiveness. Participants were randomly assigned to one of three medical nutrition therapy (MNT) groups: the MNT 1 group (n=38) received usual medical treatment, counseling from a nutritionist and diabetes educator, using carbohydrate counting (40-45% of carbohydrates)with an intensive educational component; MNT2 group (n=50) had the same treatment, but included only low-moderate glycemic index foods; and NO-MNT group (n=45) received the current hospital treatment. All women will receive a glucose meter so they do self glucose monitoring (pre and postprandial) 2 times a weeks 6 times a day. Weight gain, dietary consumption and glucose concentrations will be evaluated every two weeks. Fetal outcomes (weight, length and presence of complications)will be measured at labor.
The purpose of this study is to determine whether unrecognized maternal hyperglycemia and postprandial lipemia early or late in gestation predicts excess neonatal adiposity.
The object of this study is to evaluate patients with a diagnosis of GD who are included in a program of RE carried out with rubber tubes, comparing the frequency of women who will use insulin in the group who will participate in the program with the group that won't do the exercises, and to verify the impact of the program on the adequacy of capillary glycemic control of the pregnant women.
Women diagnosed with gestational diabetes mellitus (GDM) are at substantially increased risk of developing type 2 diabetes and obesity, currently at epidemic rates in the United States. GDM, therefore, identifies a population of women at high risk of developing type 2 diabetes and thus provides an excellent opportunity to intervene years before the development of this disorder. It is well recognized that acute as well as chronic physical activity reduce fasting plasma glucose as well as improve glucose tolerance in type 2 diabetes. Recent studies have suggested that women with higher levels of physical activity have reduced risk of GDM. Therefore, we will test the hypothesis that an exercise intervention is an effective tool for preventing GDM among women with a history of GDM.
The purpose of this pilot study is to determine if, during pregnancy, women with GDM have an exaggerated lipid response compared to non-gestational diabetics. If a difference is noted, further studies will explore the possibility of screening gestational diabetics during their pregnancy for hyperlipidemia to determine if prenatal screening can predict postpartum risk for hyperlipidemia. In addition the relationship, if any between maternal lipid dysfunction and placental disease will be explored. This will be a prospective cohort study. As part of routine prenatal care, women receive a one hour glucose challenge test to screen for gestational diabetes. Those women with elevated values then require a three hour glucose tolerance test, which is a diagnostic test for gestational diabetes. All women that are scheduled to receive a three hour GTT will be identified and ask to enroll in this study. 46 women whose three hour GTT is normal and thus do not have GDM, will be compared to 46 women with an abnormal three hour GTT and thus would have the diagnosis of GDM. Enrolled women will have a lipid panel consisting of; total cholesterol, triglycerides, HDL and LDL cholesterol at the time of their fasting glucose blood sample. In addition, a repeat lipid panel will be sent at the time of the third hour sample, to assess changes, if any due to the glucose challenge. Umbilical cord blood samples will be sent in order to obtain newborn lipid profiles. Women in both the GDM and normal groups will be asked to return 6-8 weeks
Present practice: Measurement of fasting glucose values in 2nd trimester of pregnancy, if above 4.8 mmol/l, a Glucose Tolerance Test is performed. (Two-step procedure: 1. Appointment for the fasting glucose measurement, 2. Appointment for the Glucose Tolerance Test)
The purpose of the study is to see if a low glycemic index diet will reduce blood sugar levels in pregnant women with high blood sugar levels.
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.
