Choice of standards for sonographic fetal abdominal circumference percentile.

Background: The diagnosis of abnormal fetal abdominal circumference is based on values >90th or <10th percentile. There are dozens of established norms that can be used to determine the percentile of a given abdominal circumference measurement, but there is no established method to determine which norms should be used.

Objective: This study aimed to evaluate the applicability of 5 established abdominal circumference norms to our measurements and to determine which, if any, should be used for the diagnosis of abnormal fetal abdominal circumference.

Application of a Proposed Algorithm to Cesarean Deliveries for Nonreassuring Fetal Heart Rate Tracing.

Objectives: The aim of the study is to evaluate how current management of Category II fetal heart rate tracings compares with that suggested by a published algorithm and whether these differences lead to disparate neonatal outcomes.

Study Design: This is a retrospective observational study from the resident service at an academic-community tertiary care center from 2013 to 2018. We reviewed archived fetal heart rate tracings from patients with cesarean delivery performed for nonreassuring fetal heart rate tracing and interpreted tracings against the algorithm.

Antepartum vaginal bleeding: characteristics associated with delivery within seven days.

To identify maternal and/or fetal characteristics associated with delivery within seven days for patients who present with vaginal bleeding in the antepartum period. This is a retrospective chart review performed at a community-academic tertiary care center. Three hundred and twenty-two consecutive charts associated with admission for vaginal bleeding during pregnancy between January 2015 and May 2020 were reviewed.

Maternal high-fat-diet programs rat offspring liver fatty acid metabolism.

In offspring exposed in utero to a maternal diet high in fat (HF), we have previously demonstrated that despite similar birth weights, HF adult offspring at 6 months of age had significantly higher body weights, greater adiposity, and increased triacylglycerol (TAG) levels as compared to controls. We hypothesized that a maternal HF diet predisposes to offspring adiposity via a programmed increase in the synthesis of monounsaturated fatty acids in the liver and hence increased substrate availability for liver TAG synthesis. We further hypothesized that programmed changes in offspring liver fatty acid metabolism are associated with increased liver expression of the lipogenic enzyme stearoyl-CoA desaturase-1 (SCD-1).

Placenta accreta: depth of invasion and neonatal outcomes.

Objective: The purpose of this study was to compare the risk of adverse neonatal outcomes between women with placenta accreta and placenta increta or percreta.

Methods: This was a single institution retrospective cohort study of women with abnormal placentation (placenta accreta, increta, and percreta) who delivered from 1982-2002. Cases were divided into superficial invasion (placenta accreta) and deep invasion (placenta increta or percreta), and compared.
