Performance of a local reference curve for predicting small for gestational age fetuses in pregnant women with HIV/AIDS.

Purpose: To compare the performance of a local estimated fetal weight curve with curves established for other populations to predict small for gestational age (SGA) fetuses.

Methods: A retrospective and cross-sectional study involving 231 fetuses in which the performance of a local curve (proposed model) was compared with the Hadlock and Intergrowth-21st curves in the prediction of SGA fetuses, by applying them to a population of high-risk pregnant woman with HIV/AIDS. For each model, a receiver operating characteristic curve was adjusted, considering the SGA classification by the neonatal Intergrowth method as the gold standard, and the area under the curve (AUC) was calculated.

Performance of local reference curve on the diagnosis of large for gestational age fetuses in diabetic pregnant women.

Objective: To evaluate the performance of a local fetal weight curve based on the prediction for large gestational age (LGA) newborns in diabetic pregnant women and to compare it to reference curves established for other populations.

Method: A reference model for estimated fetal weight was created from a local sample of 2211 singleton low-risk pregnancies. The estimated fetal weight from 194 women with gestational diabetes mellitus was then plotted on this curve, and the results were compared to those obtained by Intergrowth 21st and Hadlock curves.

Local References for Ultrasound-Estimated Fetal Weight Based on 2,211 Singleton Pregnancies in the City of Curitiba, South of Brazil.

Objective:  To develop reference curves of estimated fetal weight for a local population in Curitiba, South of Brazil, and compare them with the curves established for other populations.

Methods:  An observational, cross-sectional, retrospective study was conducted. A reference model for estimated fetal weight was developed using a local sample of 2,211 singleton pregnancies with low risk of growth disorders and well-defined gestational age.

[Prevention of normothermic hepatic ischemia during in situ liver perfusion with three different preservation solutions: experimental analysis by realtime infrared radiation thermography].

Objective: To establish the usefulness of infrared radiation thermography on monitoring in situ liver perfusion with different preservation solutions during liver harvesting.

Methods: Twenty-four adult male Wistar rats, weighing 385.31 g were randomly divided into four groups of six animals each according to the solution used to perfuse the liver (Euro-Collins® solution--EC group; Custodiol® solution--CUST group; Celsior® solution--CEL group and Ringer-Lactate solution--RL group).
