Medicaid eligibility expansions and improved enrollment procedures for pregnant women during the late 1980s are examined in this article. Results show that the number of births financed by Medicaid has increased dramatically, and that women are enrolling earlier in the course of pregnancy. Nevertheless, problems continue to exist. If substantial numbers of women continue to enroll late in pregn...

Lactation is the most energy-demanding phase of mammalian reproduction, and lactation performance may be affected by events during pregnancy. For example, food intake may be limited in late pregnancy by competition for space in the abdomen between the alimentary tract and fetuses. Hence, females may need to compensate their energy budgets during pregnancy by reducing activity and lowering body ...

BACKGROUND Plasmodium falciparum parasites that cause malaria in pregnancy express unique variant surface antigens (VSAs). Levels of immunoglobulin G (IgG) antibody to pregnancy-associated VSAs measured at delivery are gravidity dependent, and they have been associated with protection from disease. It is not known how these IgG responses develop in pregnant women receiving intermittent preventi...

OBJECTIVES Pregnancy loss in women suffering from hyperthyroidism has been described in case reports, but the risk of pregnancy loss caused by maternal hyperthyroidism in a population is unknown. We aimed to evaluate the association between maternal hyperthyroidism and pregnancy loss in a population-based cohort study. STUDY DESIGN All pregnancies in Denmark from 1997 to 2008 leading to hospi...

Metabolic clearance rates (MCR) of arginine vasopressin (AVP) were measured serially in five women starting before conception, during gestational weeks 7-8 (early), 22-24 (middle), and 36-38 (late pregnancy), and again 10-12 wk postpartum. Hormonal disposal rates were determined after water loading to suppress endogenous AVP release using a constant infusion method designed to achieve three dif...

Regulation of voltage-gated K(+) (K(v)) channel expression may be involved in controlling contractility of uterine smooth muscle cells during pregnancy. Functional expression of these channels is not only controlled by the levels of pore-forming subunits, but requires their association with auxiliary subunits. Specifically, rapidly inactivating K(v) current is prominent in myometrial cells and ...

The influence of maternal macronutrient balance and dietary glycemic index (GI) on neonatal body composition has received little study. We hypothesized that the overall quantity and quality of macronutrients, particularly carbohydrate, in the maternal diet could have trimester-specific effects on neonatal growth and body composition in women at risk of gestational diabetes. Maternal diet was as...

CONTEXT Little is known about the contribution of fetal alcohol exposure to the development of alcohol disorders in early adulthood. OBJECTIVE To examine the independent effect of maternal alcohol use during early vs late periods in pregnancy on the time of onset of alcohol disorders in offspring. DESIGN Follow-up study of the Mater-University of Queensland Study of Pregnancy and Its Outcom...

BACKGROUND Persistent pulmonary hypertension of the newborn (PPHN) is associated with substantial infant mortality and morbidity. A previous cohort study suggested a possible association between maternal use of the selective serotonin-reuptake inhibitor (SSRI) fluoxetine late in the third trimester of pregnancy and the risk of PPHN in the infant. We performed a case-control study to assess whet...
