Progesterone in Pregnancy: Evidence-Based Strategies to Reduce Miscarriage and Enhance Assisted Reproductive Technology.

The incidence of miscarriage in early pregnancy, between 5-20 weeks, is common, with a prevalence of between 5-22% of all pregnancies. Miscarriage can have physical, social, and mental health impacts on women and their families. In societies such as Taiwan, where the birth rate is falling and life expectancy is increasing, there is concern that factors that reduce birth rates will have detrimental economic and societal effects.

The timing of intravenous oxytocin administration is crucial to minimize perioperative blood loss during first-trimester suction curettage for missed abortion.

Background: Oxytocin is commonly used to reduce blood loss during suction curettage for missed abortion. However, the potential of oxytocin to mitigate blood loss in early pregnancy remains controversial. Based on the hypothesis that the "timing" of oxytocin administration may be a critical factor, we investigated whether the timing of intravenous (IV) administration is associated with reduced perioperative blood loss during first-trimester suction curettage for missed abortion.

The impact of prenatal use of oral Clostridium butyricum on maternal group B Streptococcus colonization: A retrospective study.

Objective: The aim of this study is to examine the effect of taking Clostridium butyricum (Miyarisan BM) orally for 4 weeks since the 32 weeks of gestation on preventing Group B Streptococcus colonization.

Materials And Methods: We retrospectively collected data on the pregnancy outcomes of 1602 women between October 2017 and August 2019. The control group received standard antenatal care, and the intervention group received standard antenatal care with a daily oral dose of probiotics since the 32 weeks of gestation.
