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.

Novel Quantitative Trait Loci for Grain Cadmium Content Identified in Hard White Spring Wheat.

Cadmium (Cd) is a heavy metal that can cause a variety of adverse effects on human health, including cancer. Wheat comprises approximately 20% of the human diet worldwide; therefore, reducing the concentrations of Cd in wheat grain will have significant impacts on the intake of Cd in food products. The tests for measuring the Cd content in grain are costly, and the content is affected significantly by soil pH.

QTL mapping for grain yield and three yield components in a population derived from two high-yielding spring wheat cultivars.

Four genomic regions on chromosomes 4A, 6A, 7B, and 7D were discovered, each with multiple tightly linked QTL (QTL clusters) associated with two to three yield components. The 7D QTL cluster was associated with grain yield, fertile spikelet number per spike, thousand kernel weight, and heading date. It was located in the flanking region of FT-D1, a homolog gene of Arabidopsis FLOWERING LOCUS T, a major gene that regulates wheat flowering.

Identification and assessment of two major QTLs for dwarf bunt resistance in winter wheat line 'IDO835'.

Two major dwarf bunt resistance QTLs were mapped to a known Bt9 locus and a novel locus. The associated KASP markers were developed and validated in other two populations. Dwarf bunt (DB), caused by Tilletia controversa J.
