Infant car seat use in Japan after the antepartum distribution of an educational leaflet: A prospective, nonrandomized controlled trial with a questionnaire survey.

To determine whether an antepartum educational leaflet distributed to parents before infant delivery affected the rate of infant car-seat (ICS) use 1 month after delivery, because to the best of our knowledge, only few reports have evaluated systematic attempts to improve the rate of always ICS use by mothers driving infants A multicenter questionnaire survey targeting pregnant Japanese women seeking antenatal care at the outpatient clinics of eight hospitals was designed. Women enrolled during the first half of the study period did not receive leaflets describing ICS safety guidelines (control group). Women enrolled during the latter half of the study period received the leaflet between gestational week 35 and 37 (intervention group).

Liver dysfunction in women with pregnancy-induced antithrombin deficiency.

Aim: The aim of this study was to determine whether women with pregnancy-induced antithrombin deficiency (PIATD) had higher risk of liver dysfunction in the absence of thrombocytopenia.

Methods: We carried out a retrospective observational study at five centers in all 129 women with incidentally found PIATD among 5249 maternities and 129 control women without PIATD matched for number of fetuses and gestational week at delivery. PIATD was diagnosed in women with antenatal antithrombin (AT) activities of ≤75% followed by a further decrease to ≤65% peripartum.
