Impact of the "39-week rule" on adverse pregnancy outcomes: a statewide analysis.

Background: The "39-week rule," adopted by the American College of Obstetricians and Gynecologists circa 2009, discouraged routine elective induction of labor in early-term gestations (37 weeks 0 days-38 weeks 6 days) to decrease the risk of adverse neonatal outcomes. However, little research exists regarding any unintended adverse pregnancy outcomes associated with this policy shift.

Objective: This study aimed to quantify the difference in incidence of adverse pregnancy outcomes before and after the implementation of the 39-week rule.

Impact of restricting early-term deliveries on adverse neonatal outcomes: a statewide analysis.

Background: The "39-Week Rule" was adopted by the American College of Obstetricians and Gynecologists in 2009 to eliminate nonmedically indicated (elective) deliveries before 39 weeks in an effort to improve neonatal outcomes.

Objective: Our primary objective was to quantify the effect of this policy change on adverse neonatal outcomes among a cohort of term births in South Carolina.

Study Design: Deidentified data from all births in the state of South Carolina from 2000 to 2008 (before the 39-week rule) and from 2013 to 2017 (after statewide implementation and enforcement of the rule) were obtained from the South Carolina Revenue and Fiscal Affairs Office.

Microbiomes of Site-Specific Dental Plaques from Children with Different Caries Status.

The oral microbiota associated with the initiation and progression of dental caries has yet to be fully characterized. The Human Oral Microbe Identification Using Next-Generation Sequencing (HOMI) approach was used to analyze the microbiomes of site-specific supragingival dental plaques from children with different caries status. Fifty-five children (2 to 7 years of age) were assessed at baseline and at 12 months and grouped as caries free (CF), caries active with enamel lesions (CAE), and caries active with dentin carious lesions (CA).
