Global burden of maternal mortality The number of maternal deaths is unconscionably high. An estimated 500,000 women die each year in pregnancy and childbirth.1 An estimated 10 million more women suffer serious maternal morbidities,2 including debilitating and socially devastating conditions such as uterine prolapses and obstetric fistulae.3 In addition, substantial proportions of the 3 million newborn deaths and 4 million stillbirths that occur each year are the result of maternal conditions or of acute events in and around the time of delivery.4 The World Health Organisation (WHO) defines maternal mortality as ‘the death of a woman while pregnant or within 42 days of termination of pregnancy or from any cause related to or aggravated by the pregnancy or its management, but not from accidental or incidental causes’, with an additional classification of ‘direct’, ‘indirect’ or ‘incidental’.5 Direct deaths result from obstetric complications, while indirect deaths result from a condition that is not directly related to obstetric causes but is aggravated by the effects of pregnancy. In developing-country settings, studies indicate that 20 per cent or more of all maternal deaths are due to indirect causes. The patterns of maternal mortality reveal large levels of inequity between and within countries – 99 per cent of maternal deaths occur in developing countries, with 86 per cent occurring in South Asia and sub-Saharan Africa alone.6 Fourteen countries have maternal mortality rates (MMRs) of at least 1,000 per 100,000 live births, of which all except Afghanistan are in sub-Saharan Africa: Afghanistan, Angola, Burundi, Cameroon, Chad, the Democratic Republic of Congo, Guinea-Bissau, Liberia, Malawi, Niger, Nigeria, Rwanda, Sierra Leone, and Somalia. Wide disparities also exist within countries. Class, too, plays a defining role in maternal mortality and morbidity statistics, with studies in multiple countries showing that the MMR amongst poor women is four times higher than amongst wealthier groups.7 Three fundamental causes of maternal mortality can be identified:8

I-17: The Mechanism of Gonadal Sex Determination
Background In mammals, a single exon gene SRY on the Y-chromosome is activated in the XY gonadal primordium and initiates a cascade of molecular and morphological events leading to testicular differentiation. SRY-encoded protein (SRY) is a transcription factor harboring a HMG-box DNAbinding motif that upregulates SOX9, which encodes another transcription factor sharing the DNA binding motif wit...
متن کاملImpaired Maternal Behavior in Usp46 Mutant Mice: A Model for Trans-Generational Transmission of Maternal Care
Usp46 mutant mice (congenic strain on a B6 genetic background; MT mice) have a low weaning rate and display poor maternal behavior compared to C57BL/6J mice (B6 mice). Based on these observations, we examined how maternal behavior is shaped by cross-fostering and in-fostering MT and B6 mice. The experiments consisted of six groups: B6 mice fostered by their biological mother (B6-CO); MT mice fo...
متن کاملAdequacy of maternal pyridoxine supplementation during pregnancy in relation to the vitamin B6 status and growth of neonates at birth.
To evaluate the adequacy of maternal pyridoxine supplementation during pregnancy for both maternal and neonatal status at birth, vitamin B6 status, assessed by plasma pyridoxal phosphate (PLP), pyridoxal (PL) and total aldehyde vitamer (PLP + PL) concentrations, and the growth of neonates, including weight, length, head and chest circumferences, were examined for 209 neonates whose mothers were...
متن کاملAn Effective Method for Detecting Y-chromosome Specific Sequences of Circulating Fetal DNA in Maternal Plasma During the First-trimester
Background and Aims: New advances in the use of cell-free fetal DNA (cffDNA) in maternal plasma of pregnant women has provided the possibility of applying cffDNA in prenatal diagnosis as a non-invasive method. One of the applications of prenatal diagnosis is fetal gender determination. Early prenatal determination of fetal sex is required for pregnant women at risk of X-linked and some endocrin...
متن کاملEmbryo transfers between C57BL/6J and DBA/2J mice: Examination of a maternal effect on ethanol teratogenesis
Genetic factors influence fetal alcohol spectrum disorders (FASDs) in both humans and animals. Experiments using inbred and selectively bred mouse stocks that controlled for (1) ethanol dose, (2) maternal and fetal blood ethanol levels, and (3) fetal developmental exposure stage, show genotype can affect teratogenic outcome. Other experiments distinguish the teratogenic effects mediated by mate...
