From January 15 through December 27, 2016, a total of 1,297 pregnancies with possible recent Zika virus infection were reported to the USZPR from 44 states (Figure 1), including 972 completed pregnancies with reported outcomes (895 liveborn infants
and 77 pregnancy losses).
Applied to a population with maternal ages similar to the entire US population delivering liveborn infants
, the Down syndrome detection rate and false-positive rate for laboratory 1 were expected to be 82.
The subjects for the current study were identified in a retrospective review of placental pathologic conditions in liveborn infants
with IUGR, which was described in our previous report.
Among liveborn infants
, 59% had Zika laboratory testing results reported to the pregnancy and infant registries.
The researchers reported on a case series of 1,501 liveborn infants
with suspected congenital Zika virus syndrome reported in Brazil.
DS is the most common chromosomal disorder in liveborn infants
, with no predilection for race or socioeconomic group.
6% to 30% of cases of MSAF, and 1% to 3% of liveborn infants
Abruptio placentae is a serious condition with a high mortality rate; liveborn infants
frequently have neonatal complications, including birth asphyxia and the hazards of prematurity, what rises the need for medical intervention.
A prospective cohort study was done among 681 HIV positive pregnant women in the Latin American and Caribbean region receiving one of three different antiretroviral regimens for at least 28 days during pregnancy and who delivered liveborn infants
with known birthweight and gestational age in 2005.
Of these referrals, 8886 were from liveborn infants
Of a total of 23 035 liveborn infants
, 21 086 weighed [greater than or equal to] 2000 g at birth.
Of the 4,555 infants, 433 had craniosynostosis verified by radiographic imaging and 4,122 liveborn infants
without major birth defects served as the control group.
