Variance components for a sire-maternal grandsire (MGS) threshold model were estimated from subsets of the US calving ease (CE) database, which includes over 10 million calving records with CE scored 1 (no problem) to 5 (extreme difficulty). Selected records included sire and MGS among the 2601 most frequently appearing bulls. The data were further restricted by requiring at least 20 records in...

To assess the relationship between maternal and fetal mineral homeostasis, serum calcium, magnesium, inorganic phosphate, parathyroid hormone, and vitamin D metabolite concentrations in venous cord sera from 15 preterm singletons and 3 twin pairs were compared with the levels found in maternal sera. Cord calcium, magnesium, and phosphorus levels were significantly higher than the respective lev...

Background Pre-eclampsia and the subsequent eclampsia account for a common cause of maternal mortality worldwide and efforts aimed at reducing its menace are vital. Objective To estimate the serum magnesium levels in pre-eclampsia and eclampsia and to study the effect of using different regimens of magnesium sulphate. Methods 70 cases of pre-eclampsia and eclampsia and 35 normal pregnant women ...

Introduction: There is a great deal of controversy regarding the effect of gestational magnesium (Mg) deficiency on fetal growth and the incidence of low birth weight (LBW) in infants. Therefore, this study aimed to delineate the possible relationship between maternal Mg level and infant LBW. Methods: This case-control study was conducted on 180 mothers in Shiraz, Iran. Fasting blood samples we...

s: Background: In fluorosis endemic area, the amount of fluoride transferred to the fetus is significant in determining the early onset of fluorosis. The role played by placenta in transporting fluoride and other ions which are present in high concentrations in the local drinking water is studied. Aims & Objectives: The aim of the present study is to decipher the role of placenta in transport o...

In the US, the routine use of magnesium sulfate for seizure prophylaxis in women with preeclampsia is an ingrained obstetric practice. During the past decade, several observational studies and randomized trials have described the use of various regimens of magnesium sulfate to prevent or reduce the rate of seizures and complications in women with preeclampsia. There are only 2 double-blind, pla...

Maternal mortality in Brazil is a major problem. It is about 10 times that of Canada or England. What do these three countries have in common regarding maternal mortality? Hypertension in pregnancy, a major cause of maternal death in developed and developing countries. Among the hypertensive complications of pregnancy, pre-eclampsia and eclampsia are of utmost importance when considering any st...

OBJECTIVE Magnesium historically has been used for treatment and/or prevention of eclampsia or preterm labor. More recently, antepartum magnesium sulfate has been suggested for prevention of cerebral palsy in preterm infants. Although adverse effects and toxicity of magnesium in pregnant women are well known, the fetal-neonatal effects of magnesium are less clear. The objective of this study wa...

Background: Eclampsia is a hypertensive disorder related to pregnancy, in which there is occurrence of one or more generalized convulsions and or coma, in the absence of other neurologic conditions. It is a common obstetric emergency. Eclampsia is associated with elevated maternal and fetal morbidity and mortality. Objectives: To compare the efficacy of low dose magnesium sulphate (Dhaka) regim...

BACKGROUND Magnesium sulphate has been used in some settings as a tocolytic agent to inhibit uterine activity in women in preterm labour with the aim of preventing preterm birth. OBJECTIVES To assess the effects of magnesium sulphate therapy given to women in threatened preterm labour with the aim of preventing preterm birth and its sequelae. SEARCH METHODS We searched the Cochrane Pregnanc...
