Management of Isolated Fever in Labour Compared with Clinical Chorioamnionitis in a Quaternary Centre.

Objectives: To investigate treatment patterns of women with isolated fever in labour and evaluate if variables in the sepsis in obstetrics score (SOS) or fetal tachycardia are associated with treatment differences. Our secondary objective was to compare women with isolated fever in labour with women with clinical chorioamnionitis to identify any clinicodemographic differences.

Methods: A retrospective cohort study of 473 patients at BC Women's Hospital who presented with isolated fever in labour between January 2011 and April 2016 compared with a dataset of 1135 women with clinical chorioamnionitis from 2011 to 2016 in the same institution.

Complement C3 Drives Autophagy-Dependent Restriction of Cyto-invasive Bacteria.

In physiological settings, the complement protein C3 is deposited on all bacteria, including invasive pathogens. However, because experimental host-bacteria systems typically use decomplemented serum to avoid the lytic action of complement, the impact of C3 coating on epithelial cell responses to invasive bacteria remains unexplored. Here, we demonstrate that following invasion, intracellular C3-positive Listeria monocytogenes is targeted by autophagy through a direct C3/ATG16L1 interaction, resulting in autophagy-dependent bacterial growth restriction.
