INTRODUCTION In sub Saharan Africa, childbirth remains a challenge that creates the need for additional screening tools. Maternal pelvis height, which is currently in use by automotive engineers has previously been shown to have significant associations with various childbirth related outcomes and events. This study set out to determine the associations between maternal: Age, height, weight and...

OBJECTIVE to analyze the factors associated to toxoplasmosis-related knowledge among pregnant women attending public health services in the municipality of Niterói, Rio de Janeiro, Brazil. METHODS this is a cross-sectional study conducted with pregnant women assisted in eight health care units; data was collected using a standardized questionnaire, from April 2013 to February 2015. RESULTS ...

The higher costs of sons compared with daughters extends to a negative effect of brothers on the lifetime reproductive success of their siblings in subsistence and preindustrial societies. In societies with fewer resource constraints, one might expect that these effects would be limited or non-existent. This study investigates the costs of brothers and sisters in a contemporary western society ...

Aim: To summarize recent articles on the risk factors of preeclampsia in twin pregnancies from 2002 to 2014. Methods: Recent articles from 2002 to 2014 were searched using PubMed. Results: We found 8 articles analyzing the risk factors of preeclampsia in twin pregnancies and focused on the following three risk factors: i) egg (oocyte) donation, ii) chorionicity (dichorionic (DC) twins vs. monoc...

Multiple pregnancies have increased from 9 per 1000 pregnancies in the 1970s to 14 per 1000 pregnancies. Multiple births account for 10% of perinatal deaths (8% of fetal deaths and 14% of neonatal deaths). Compared to singletons births, the perinatal mortality rate is four times higher in twins, and nine times higher in multiple births of a higher order. The cerebral palsy rate among survivors ...

As the success rates of IVF clinics improve, one of the adverse consequences is the increased incidence of twins, due largely to the number of embryos transferred. Even if the number of embryos transferred is restricted to two, the twinning rate can exceed 40% of the pregnancies. An obvious way to reduce this high twin rate would be to transfer only one embryo. This would require that cryoprese...

OBJECTIVE To estimate the difference between levels of the two biochemical markers pregnancy-associated plasma protein-A (PAPP-A) and maternal serum free β-human chorionic gonadotropin (free β-hCG) in twin pregnancies relative to singleton pregnancies and establish an improved screening procedure for chromosomal abnormalities such as trisomy 21 in twin pregnancies. METHODS 4843 unaffected and...

BACKGROUND Egg donation (ED) makes it possible for subfertile women to conceive. Pregnancies achieved using ED with unrelated donors are unique, since the entire fetal genome is allogeneic to the mother. The aims of this review were to evaluate the consequences of ED pregnancies and to place them in the special context of their atypical immunologic relationships. METHODS This review comprised...
