The fact that venomous snakebites during pregnancy result in a high fetal wastage and that both venomous snake and spider bites may cause maternal mortality, makes this an important, albeit uncommonly encountered, entity in obstetrics. Perhaps the most difficult aspect of dealing with this clinical situation is that care must ...
Foster S F - - 1996
The aim of this study is to make a preliminary examination of the relationship between body satisfaction, maternal fetal attachment, and breast or bottle feeding plans in pregnancy. Thirty eight women between 32 and 38 weeks pregnant were examined by means of the Maternal Foetal Attachment Scale, the Eating Disorders ...

The demands of fetal growth lead to an adaptation of maternal homeostasis in order to provide the required calcium from enhanced intestinal absorption rather than from mobilization of maternal skeletal reserves. In large part this adaptive process depends on the interrelationship between PTH and 1,25(OH)2D which shows quantitative rather than ...

PURPOSE: To examine the relationships among a woman's attachment to her fetus, the presence of postpartum depressive symptoms, and subsequent perceptions of maternal role attainment three months after birth DESIGN: A longitudinal, panel design SETTING: Hospital-sponsored childbirth education classes PARTICIPANTS: Primiparous women (N = 136) at 24-40 weeks of pregnancy ...
Levy H L - - 1996
Phenylketonuria (PKU) produces white matter changes identifiable by magnetic resonance imaging. These changes occur postnatally. Offspring of untreated mothers with PKU also have a brain effect, expressed as microcephaly and mental retardation. This effect occurs prenatally. To determine whether the white matter changes seen in PKU are also present in ...
Rothenberg S J - - 1996
We constructed models of umbilical cord blood lead (PbB), with and without the addition of maternal PbB at delivery and earlier in pregnancy, to determine which factors explaining cord PbB depended upon maternal PbB and which did not. We prospectively studied women of low-to-middle socioeconomic status who lived in the ...
Levy H L - - 1996
The maternal phenylketonuria (PKU) syndrome refers to the teratogenic effects of PKU during pregnancy. These effects include mental retardation, microcephaly, congenital heart disease, and intrauterine growth retardation. In untreated pregnancies wherein the mother has classic PKU with a blood phenylalanine level > or = 1,200 microM (20 mg/dl), the frequencies ...
Haig D - - 1996
Pregnancy is traditionally viewed as a harmonious collaboration between mother and fetus. From this perspective, viviparity poses a series of problems that maternal and fetal genes work together to solve and the many complications of pregnancy are interpreted as evidence of the malfunctioning of an evolved system or of the ...

Essential fatty acids (EFA) are vitally important structural elements of cell membranes and, therefore, instrumental in the formation of new tissues. The primary EFA cannot be synthesized by man and, consequently, humans depend on dietary sources for an adequate EFA supply. Fetal development is associated with a high EFA requirement, ...

Cardiopulmonary bypass (CPB) does not appear to cause excessive maternal risk, but the potential for fetal complications is of great concern. In general, operative intervention should be delayed until at least the second trimester. When this is not possible, ethical issues arise and a clash of maternal autonomy versus "fetal ...
Montemagno R - - 1995
A cross-sectional study of 64 women and their fetuses undergoing cordocentesis at 18-25 weeks showed no significant correlation between maternal and fetal Hb or MCV and no relationship between these measurements and fetal abdominal circumference. We found no evidence for a nutritional or physiological association between maternal and fetal haematological ...

Most mammals display an immediate onset of maternal care towards their offspring at parturition. In contrast, inexperienced, nulliparous females are often slow responders and show less intensity in their maternal responses. The transition from a slow responder in non-parous females to a rapid response at parturition is facilitated by the ...
Rosenblatt J S - - 1994
Psychobiological studies of maternal behavior among non-primate mammals have arrived at several general conclusions that may aid in our understanding of human maternal behavior and in the clinical treatment of parenting disorders. The hormonal basis of maternal behavior arises during pregnancy and consists of a hormonal priming phase, extending over ...

The relationship of haemolytic disease of the newborn (HDN) to the transplacental passage of the four IgG subclasses was assessed at various gestational ages by comparing the maternal and fetal IgG subclass concentrations in 34 pregnancies at risk of HDN with those in 30 pregnancies not at risk. Higher maternal ...
Haig D - - 1993
Pregnancy has commonly been viewed as a cooperative interaction between a mother and her fetus. The effects of natural selection on genes expressed in fetuses, however, may be opposed by the effects of natural selection on genes expressed in mothers. In this sense, a genetic conflict can be said to ...
Fuller S G - - 1993
Although the development of a positive relationship between the mother and infant most likely begins during pregnancy, the correlates of maternal-fetal attachment are poorly understood. This study examined the influence of family functioning on maternal-fetal attachment in a sample of varied ethnic and socioeconomic backgrounds. The authors surveyed 339 pregnant ...
Koch R - - 1993
Neonatal screening for phenylketonuria (PKU) has created an unexpected problem as females with PKU are reaching childbearing age. Surveys have revealed that maternal phenylalanine blood concentrations above 1200 mumol/L are associated with microcephaly, mental retardation, congenital heart defects, and intrauterine growth retardation among their offspring. It is estimated that as ...
