Thromboembolism following cesarean section: a retrospective study.

Objectives: As thromboembolism (TE) continues to be one of the principal causes of death in obstetrical patients and as the postpartum period is associated with the highest risk for TE, we sought to determine the risk factors associated with TE following cesarean section (CS).

Methods: A retrospective analysis of patients who had CS at a large tertiary referral center was conducted. Patients were identified through hospital medical records and were contacted approximately 1 year following their CS.

Total Breast-Feeding Duration and Dental Caries in Healthy Urban Children.

Social attraction mediated by fruit flies' microbiome.

Larval and adult fruit flies are attracted to volatiles emanating from food substrates that have been occupied by larvae. We tested whether such volatiles are emitted by the larval gut bacteria by conducting tests under bacteria-free (axenic) conditions. We also tested attraction to two bacteria species, Lactobacillus brevis, which we cultured from larvae in our lab, and L.
