Filter by:The hypothesis for this study is that women with different physiologic subtypes of gestational diabetes (GDM) (insulin secretion deficit vs. insulin sensitivity deficit) will differ in their glycemic responses to meals with different portions of dietary macronutrients. Investigators will determine GDM subtype based on glucose and insulin levels taken at multiple time points during an oral glucose tolerance test. Participants will consume two meals with different macronutrient content while wearing a continuous glucose monitor which will allow investigators to assess the glycemic response to the meals.
The Environmental Factors and Embryonic Development Project was set up to investigate environmental exposures and behavioral factors responsible for embryonic dysplasia and gestational complications in pregnant women.
The proposed project sought to develop a culturally- and individually-tailored, plain-language Spanish/English mobile phone intervention for Latinas with prior gestational diabetes (GDM). The intervention is based on earlier in-person to online modification of the CDC-funded Diabetes Prevention Program (DPP), for women with prior GDM led by co-investigator Dr. Ellen Seely of Brigham and Women's Hospital.
Gestational diabetes (GDM) impacts 1 in 10 pregnancies; hyperglycemia and hypertriglyceridemia are common features of the condition. Women are recommended to do at least 150 minutes of moderate-intensity aerobic activity a week during pregnancy and the postpartum period. Exercise both during and out of pregnancy has been shown to be an effective non-pharmacologic tool to reduce glucose and lipid profiles. The goals and purpose of this pilot study is to 1) determine the influence of exercise and the timing of exercise surrounding a meal on glucose and lipid metabolism in pregnant women with GDM and 2) determine the feasibility of low-resistance and aerobic activity and measuring exercise metrics during pregnancy. The overarching objective of this study is to determine the effects of low-resistance and aerobic exercise on glucose and lipids following a meal in pregnant women with GDM.
This study aims to obtain preliminary data for utility of alternate biomarkers for monitoring glucose control in diabetic women during pregnancy and/or predicting risk of adverse neonatal events in these women.
To conduct a randomized trial to determine the effect of Targeted Lifestyle Change Group Prenatal Care (TLC) on maternal and neonatal outcomes in women at high risk for developing gestational diabetes mellitus (GDM).
The purpose of this controlled, randomized intervention is to investigate whether a carbohydrate-restricted diet, having a positive effect on blood sugar and weigh maintaining in diabetes, is effective and safe for pregnant woman with GDM and safe for their offspring, when compared to the standard carbohydrate content diet.
Pregnancy is a vulnerable period for both a mother and her developing child. The investigator hypothesizes that diet-induced glucose excursions in the pregnant mother are a key contributor to unfavourable brain development and epigenetic marks in the developing child. It is long known that metabolic conditions are influenced by maternal nutrition and that this can impact the unborn infant. The most prominent example is gestational diabetes (GDM). It is unclear at what point unfavourable changes in brain development occur during pregnancy. Unlike many previous trials, we plan to introduce healthy diet early in the first trimester. Comparative analyses of DNA methylation patterns in the offspring of women with or without GDM revealed preferentially methylated genes, particularly in pathways linked to metabolic diseases. NuPreGDM is a randomized, controlled, open label intervention trail. The investigator aims to assess the effect of individual diet counselling combined with CGM compared to regular diet on glucose levels and postprandial glycemic excursions during an OGTT in pregnancy. The investigator wants to assess the effect of dietary counselling combined with continuous glucose monitoring on GDM risk, glycaemia and pregnancy outcome, starting in the first trimester. The investigator further hypothesizes that improved glucose levels by a healthy diet will affect brain activity of the infant and prevent unfavourable epigenetic modifications. The investigator plans to include 50 pregnant women within gestational week 4 and 14 after the last menstruation, with elevated risk for development of (GDM). Participants will be randomized 1:1 to either "diet modification group" (intervention) or to "standard diet group" (control). In the current trial, the investigator aims to modulate maternal metabolism with periodic personalized diet counselling on the basis of continuous glucose monitoring (CGM) compared to regular diet throughout pregnancy. The investigator propose that a reduction in glucose excursions in the mother will lead to a healthy environment for the developing child and prevent altered brain activity in utero, which will be assessed by fMEG (fetal magnetoencephalography) during a 75g OGTT in gestational week 28. The investigator further planned to examine child's leucocytes from cord blood to assess whether a healthy diet of the mother prevented epigenetic alterations due to improved maternal glycaemia, as exploratory endpoint. The development of blood sugar levels of the mother postpartum will be assessed by an further OGTT 6-12 weeks postpartum.
The National Diabetes Prevention Program (NDPP) is a widely available, evidence-based intervention that promotes weight loss to prevent type 2 diabetes; however, participant attendance is problematic and leads to suboptimal weight loss, especially among Hispanic, non-Hispanic black, and low-income non-Hispanic white participants. An innovative pre-session enhancement to the NDPP (Pre-NDPP) showed successful results upon initial application in a diverse and predominately low-income population, with doubled attendance and weight loss outcomes as compared to previous NDPP participants who did not receive a pre-session. If Pre-NDPP is shown to be successful upon more rigorous study, it can be widely adopted by NDPP providers across the country to help reduce diabetes prevalence and related health disparities.
Gestational diabetes mellitus (GDM), defined as hyperglycemia with blood glucose values above normal but below those diagnostic of DM, and iron deficiency (ID) with or without anemia (IDA) are common during pregnancy. Both disease patterns are associated with an increased risk of complications during pregnancy and at delivery and may have a variety of negative effects on different aspects of child development. Thus, GDM and ID/IDA during pregnancy should be prevented. Whether iron supplementation with high oral doses acutely increases hepcidin during pregnancy, and whether this acute iron-induced increase in hepcidin decreases insulin sensitivity, is uncertain.
