OBJECTIVE We sought to define 24-h glycemia in normal-weight and obese pregnant women using continuous glucose monitoring (CGM) while they consumed a habitual and controlled diet both early and late in pregnancy. RESEARCH DESIGN AND METHODS Glycemia was prospectively measured in early (15.7 ± 2.0 weeks' gestation) and late (27.7 ± 1.7 weeks' gestation) pregnancy in normal-weight (n = 22) and ...

In utero, glucose utilization by fetal muscles (heart and hindlimb) displays important interspecies differences. In the fed state, it is 5-fold higher in rat than in rabbit fetal muscles. Maternal fasting induces a decrease in glucose utilization in fetal muscles of the rat but not of the rabbit.

BACKGROUND Recent studies have reported beneficial effects of probiotics on maternal glycemia in healthy pregnant women. Obesity significantly increases risk of impaired glucose tolerance in pregnancy, but glycemic effects of probiotics in this specific obstetric group require additional investigation. OBJECTIVE The aim of the Probiotics in Pregnancy Study was to investigate the effect of a p...

INTRODUCTION Birthweight is used as an indicator of intrauterine growth, and determinants of birthweight are widely studied. Less is known about determinants of deviating patterns of growth in utero. We aimed to study the effects of maternal characteristics on both birthweight and fetal growth in third trimester and introduce placental weight as a possible determinant of both birthweight and fe...

OBJECTIVE Common genetic variants in GCK and TCF7L2 are associated with higher fasting glucose and type 2 diabetes in nonpregnant populations. However, their associations with glucose levels from oral glucose tolerance tests (OGTTs) in pregnancy have not been assessed in a large sample. We hypothesized that these variants are associated with quantitative measures of glycemia in pregnancy. RES...

During pregnancy, maternal calcium needs increase as a result of increasing calcium requirements for fetal bone development. These needs have to be completely supplied by the mother via placental transfer. Several studies link low serum ionized calcium concentrations with the development of hypertension and pregnancy-induced hypertension. We hypothesized that maternal hypocalcemia would develop...

Many Muslim women worldwide are pregnant during Ramadan and adhere to Ramadan fasting during pregnancy. In the present study, we determined whether maternal adherence to Ramadan fasting during pregnancy has an impact on the birth weight of the newborn, and whether the effects differed according to trimester in which Ramadan fasting took place. A prospective cohort study was conducted in 130 pre...

M aturity-onset diabetes of the young (MODY) encompasses a collection of distinct forms of diabetes, which are inherited in an autosomaldominant mode from the maternal or paternal side of the family or occasionally occur as a de novo mutation. All the genes involved affect either b-cell sensing or insulin secretion (1). The clinical presentations of MODY are heterogeneous, reflecting the differ...

BACKGROUND Islam clearly exempts fasting in Ramadan during sickness, pregnancy, and breastfeeding. Yet, some women prefer to fast despite realizing their increase in nutritional demand during pregnancy. Nurses and other healthcare providers face a difficult task of providing appropriate medical advice to Muslim women regarding the safety and impact of their fasting. The present study was conduc...
