These studies investigate glomerular hemodynamic responses to pregnancy in rats with 5/6th reduction of renal mass of four weeks duration. Both preglomerular and efferent arteriolar resistances (RA and RE) fell significantly at midterm although single nephron glomerular filtration rate (SNGFR) and glomerular plasma flow (QA) were unchanged versus virgins. In late pregnant rats with reduction of...

Over the past 25 years the rate of twin and higher - order multifetal birth have increased between 1980 and 2005. The twining rate rose from 18.9 to 32.1 per 1000 live birth. Multifetal gestations are at high risk of fetaland complication such as; growth restricted fetal death, LBW and cerebral palasy. Maternal complication are that also increased such as: preeclampsia, diabetes, maternal death...

We analyze the relationship between prenatal WIC participation and birth outcomes in New York City from 1988-2001. The analysis is unique for several reasons. First, we restrict the analysis to women on Medicaid and or WIC who have no previous live births and who initiate prenatal care within the first four months of pregnancy. Our goal is to lessen heterogeneity between WIC and nonWIC particip...

METHODS We examined trichorionic triplet pregnancies with three live fetuses at 10-14 weeks of gestation that were managed expectantly or by ER. The two groups were compared for the rates of miscarriage, defined as pregnanc...
