The topics of the studies include the effect of digital rotation of the baby in occipito-posterior position on position at birth and birth outcomes; temperature disturbances during skin-to-skin contact among babies exposed to epidural analgesia and exogenous oxytocin during labor; the prevalence of and motivations for "maternal request" cesarean surgery; and the benefits of delayed clamping of the umbilical cord after birth.
