Review Meta AnalysisVitamin D and risk of preterm birth: Up-to-date meta-analysis of randomized controlled trials and observational studies.
We performed a meta-analysis of randomized controlled trials (RCT) and observational studies to answer the two following questions: (i) whether low maternal circulating 25 hydroxyvitamin D (25-OHD) is associated with an increased risk of preterm birth (PTB) or spontaneous PTB (sPTB); and (ii) whether vitamin D supplementation alone during pregnancy can reduce the risk of PTB. ⋯ Maternal circulating 25-OHD deficiency could increase PTB risk and vitamin D supplementation alone during pregnancy could reduce PTB risk. Extrapolation of the results, however, must be done with caution, and there is urgent need for larger, better-designed RCT to confirm this effect.

Conservative management of post-partum hemorrhage secondary to placenta previa-accreta with hypogastric artery ligation and endo-uterine hemostatic suture.
The aim of this study was to investigate maternal and neonatal outcomes of conservative management of post-partum hemorrhage due to placenta previa-accreta using hypogastric artery ligation and endo-uterine hemostatic suture to lower uterine segment. ⋯ Conservative treatment of post-partum hemorrhage secondary to placenta previa-accreta with hypogastric artery ligation and endo-uterine hemostatic sutures to the lower segment of the uterus is associated with lower hysterectomy rate compared with the other conservative methods reported in the literature.
