A cohort study of the perinatal outcome of radiofrequency ablation in complicated monochorionic multiple pregnancies based on a different needle insert angle.

Objective: To compare the pregnancy outcomes of radiofrequency ablation (RFA) for complicated multiple pregnancies between fetal abdominal and dorsal needle insertion angles.

Methods: We performed a historical cohort study of patients who underwent selective reduction using RFA through different needle insertion angles from 2015 to 2018 at a local hospital. Dorsal needle insertion cases were consecutively selected and abdominal needle insertion cases were selectively enrolled.

Prenatal and perinatal outcomes of twin pregnancy discordant for one fetus with nuchal translucency above the 95th percentile.

Objective: To compare prenatal and perinatal outcomes of twin pregnancies in which one twin the nuchal translucency (NT) was above the 95th percentile in dichorionic twins (DCT) and monochorionic twins (MCT).

Method: In this retrospective study, 93 twin pregnancies (186 fetuses) in which one twin the NT was above the 95th percentile and the co-twin had normal NT were analyzed. Results of of G-banding and Chromosomal microarray (CMA), ultrasound findings and pregnancy outcomes were reviewed.

Analysis of amino acids and acylcarnitines profiles in small, appropriate, and large for gestational age neonates.

Objective: To identify the amino acid (AA) and acylcarnitines (ACs) profiles in dry blood spot (DBS) of small, appropriate and large for gestational age neonates, and to investigate the difference AA and AC profiles in groups.

Methods: Eight thousand nine hundred and fourteen healthy singleton newborns were divided into three groups: small for gestational age (SGA) ( = 713), appropriate for gestational age (AGA) ( = 7866), and LGA ( = 335). Electrospray ionization tandem mass spectrometry was taken to evaluate the concentrations of 11 AAs and 31 ACs in DBS specimens obtained from all enrolled neonates.
