Neurosurgical Mission to Ukraine.

Ukrainian health care before 2021 was like that in comparable middle-income countries. The conflict with Russia over the last 8 months has added significant burden to the already resource-constrained system. We describe the current neurosurgical situation in Ukraine as well as remote and in-person efforts to provide needed assistance to Ukrainian neurosurgical colleagues.

PHLDA2 gene polymorphisms and risk of HELLP syndrome and severe preeclampsia.

Objective: Pleckstrin homology-like domain, family A, member 2 (PHLDA2) is a maternally expressed imprinted gene. Loss of imprinting in PHLDA2 is associated with abnormal placental development and fetal growth restriction. Our objective was to determine whether genetic variation in PHLDA2 is also associated with risk of HELLP syndrome and preeclampsia (PE) with severe features.

Web-based comparison of historical vs contemporary methods of fetal heart rate interpretation.

Background: Contemporary interpretation of fetal heart rate patterns is based largely on the tenets of Drs Quilligan and Hon. This method differs from an older method that was championed by Dr Caldeyro-Barcia in recording speed and classification of decelerations. The latter uses a paper speed of 1 cm/min and classifies decelerations referent to uterine contractions as type I or II dips, compared with conventional classification as early, late, or variable with paper speed of 3 cm/min.

Interobserver reliability of fetal heart rate pattern interpretation using NICHD definitions.

Objective: To evaluate the interobserver reliability of fetal heart rate (FHR) pattern definition and interpretation assessed by physicians at various levels of training using standard Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) definitions and standard principles of interpretation.

Study Design: We conducted an interrater reliability study of the intrapartum FHR tracings of 32 singleton term pregnancies at Los Angeles County-University of Southern California (LAC + USC) Medical Center. Analysis included the 5 hours immediately preceding delivery, divided into 10- minute segments.
