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.

Using hybrid angle/distance information for distributed topology control in vehicular sensor networks.

In a vehicular sensor network (VSN), the key design issue is how to organize vehicles effectively, such that the local network topology can be stabilized quickly. In this work, each vehicle with on-board sensors can be considered as a local controller associated with a group of communication members. In order to balance the load among the nodes and govern the local topology change, a group formation scheme using localized criteria is implemented.
