Performance of fetal middle cerebral artery peak systolic velocity for prediction of anemia in untransfused and transfused fetuses: systematic review and meta-analysis.

Objective: To evaluate the performance of fetal middle cerebral artery peak systolic velocity (MCA-PSV) ≥ 1.5 multiples of the median (MoM) for the prediction of moderate-severe anemia, in untransfused and transfused fetuses.

Methods: A systematic search was performed to identify relevant observational studies reported in the period 2008-2018 that evaluated the performance of MCA-PSV, using a threshold of 1.

Partial trisomy 9: prenatal diagnosis and recurrence within same family.

Trisomy 9 can be suspected and confirmed in the prenatal period since the 11-13.6 weeks of screening. In cases of partial trisomy 9, the diagnosis is important especially to counseling the couple due to the increased likelihood of recurrence in subsequent pregnancies.

Testing the efficacy of a new procedure for reducing faking on personality tests within selection contexts.

The authors propose a new procedure for reducing faking on personality tests within selection contexts. This computer-based procedure attempts to identify and warn potential fakers early on during the testing process and then give them a chance for recourse. Two field studies were conducted to test the efficacy of the proposed procedure.
