Labor induction is when an external agent is employed to stimulate contractions before the onset of spontaneous labor.
Labor augmentation uses the same techniques as labor induction but uterine contractions (frequency, duration and strength) are enhanced once labor has started.
Labor induction is generally indicated when the benefits of delivery outweigh the risks of continuing the pregnancy.
Women at 42 weeks of gestation who chose not to undergo labor induction should be monitored more often with at least twice-weekly assessment of fetal well-being (cardiotocography & estimation of maximum amniotic pool depth by ultrasound).

The substitution of isoleucine to leucine at amino acid 97 (I97L) in the core region of the hepatitis B virus (HBV) seems to reduce its potency, decreasing the efficiency of both infection and the synthesis of the virus’ covalently closed circular (ccc) DNA, reports a new study presented at The Liver Meeting Digital Experience by the American Association for the Study of Liver Diseases (AASLD 2020).
