Application of 4 birthweight curves and local reference range at a University Hospital of Rio de Janeiro, Brazil.

Background: Numerous fetal growth curves have been developed from various subpopulations and geographic locations worldwide.

Objective: To determine the birthweight standard at the Maternity School and compare it to currently used standards in the clinical practice services.

Study Design: Cross-sectional, observational, and descriptive study.

The prevalence and perinatal repercussions of preeclampsia after the implementation of a prophylaxis protocol with aspirin.

Objectives: To evaluate the prevalence and perinatal repercussions of preeclampsia (PE) after the implementation of a prophylaxis protocol with aspirin in singleton pregnancy at Maternity School of Federal University of Rio de Janeiro, Rio de Janeiro, Brazil (2015-2106).

Methodology: PE prevalence according to gestational age (GA) and the prevalence ratio (PR) between PE and prematurity, small for gestational age (SGA), and fetal death were calculated in patients assisted during 2015 and 2016.

Results: PE occurred in 373(10.

External validation of first trimester combined screening for pre-eclampsia in Brazil: An observational study.

Objective: To validate a combined algorithm for early prediction of pre-eclampsia (PE) in the Brazilian population.

Study Design: This is an unplanned secondary analysis of a cohort study. Consecutive singleton pregnancies undergoing first-trimester screening for PE involving examination of maternal characteristics, medical history, and biophysical markers were considered eligible.
